Bee stings of the cornea are rarely reported, but have the potential for causing serious ophthalmological injuries. We present a case of corneal bee sting with retained stinger apparatus. A 35-year-old patient presented with an acute, corneal bee sting of the right eye 12 hours after he was stung. The patient suffered from pain, blurred vision, and epiphora. The right eye showed edema of the upper and lower eyelid, conjunctival hyperemia, chemosis, and striate keratitis of the paracentral cornea by biomicroscopic examination. The stinger was identified in the depth of the corneal infiltration. Visual acuity was 5/10. It was removed surgically. After 2 months, the eye only showed a minimal residual corneal opacification. Visual acuity was 10/10. We present a case of bee sting to the cornea with retained stinger apparatus and treatment of this unusual presentation.

Ocular injury resulting from rooster attacks is rarely reported in the literature. Sadly, the target of these attacks is most often children younger than 3 years old, whose naivete of the aggressive, territorial behavior of birds can place them at risk. Acute sequelae of these attacks can result in a lifetime of visual impairment. The possibility of a subacute or occult infection is an unusual occurrence that must always be considered. In an effort to prevent future attacks and ocular casualties, we present a case of a 12-month-old boy who suffered an open globe following a rooster attack. The open globe was emergently repaired. One week later, a white cataract was noticed on examination in the absence of systemic or ocular signs of inflammation. Traumatic endophthalmitis and lenticular abscess were suspected during examination under anesthesia. Vitrectomy, lensectomy, and injection of intravitreal antibiotics were performed. Culture of lenticular and vitreous aspirates grew alpha-streptococcus. Alpha-streptococcal endophthalmitis can result from ocular injuries caused by rooster pecking. The infection may present insidiously and without typical ocular or systemic symptoms or signs. Management is challenging and may require surgery.

Although semen quality has been discussed extensively with regard to age and season in the andrology literature, the results vary and firm conclusions are still outstanding. To investigate seasonal and age-related variations in human semen parameters, we analyzed data that were collected from an andrology clinic population. We performed a retrospective review of 551 semen analysis records collected from 1989 to 2000 from the Vincent Memorial Andrology Laboratory at Massachusetts General Hospital. Semen volume, sperm concentration, total sperm count, motility, total motile sperm, and morphology significantly decreased as age increased. In addition, as age increased, the percentage of sperm with tail defects increased. Sperm concentration was significantly higher in winter (mean 157.9 million/mL) than in fall (mean 119.1 million/mL) (P <.05). The mean percentage of sperm with normal morphology was significantly higher in winter (9.2%) than in summer and spring (7.0% and 7.5%, respectively; P <.05). The mean percentage of sperm with head defects was significantly higher in fall and summer (74.0% and 72.3%, respectively) than in winter (68.6%; P <.05). Seasonal variations were found in sperm concentration and morphology, with higher sperm concentrations in winter than in fall, and a greater percentage of sperm with normal morphology in winter than in spring and summer. Sperm concentration was lowest in the fall, whereas the percentage of sperm with normal morphology was lowest in summer. Semen volume, sperm concentration, total sperm count, motility, total motile sperm, and morphology decreased as age increased.

Males of the bedbug, Cimex lectularius, traumatically inseminate females by inserting a needle-like intromittent organ (penis) through the female's abdominal wall after she has fed. We demonstrate that: (i) mating duration determines ejaculate size; (ii) a female's first copulation in a bout of copulations always lasts longer than subsequent copulations; (iii) the intromittent organ bears sensillae; (iv) males use their intromittent organ to 'taste' whether their current mate has recently copulated; and (v) the consequence of detecting female mating status is the reduction of copulation duration and ejaculate size. We discuss why male bedbugs might show this pattern of ejaculate-size adjustment.

Summation of it from a different site:
Men who view pornographic images of two men and a woman produce better-quality sperm than men viewing pornographic images of just women, an Australian study reveals.
The finding suggests that humans may be capable of subconsciously increasing semen quality when faced with the possibility that their sperm will have to outrun those of other men in a woman’s reproductive tract.
In the study, zoologists Leigh Simmons and Sarah Kilgallon of the University of Western Australia in Perth asked 52 heterosexual men aged between 18 and 35 years to ejaculate into a container after viewing the two types of image.
The volunteers had previously abstained from sexual activity for two to six days. In samples from men who viewed the images containing the two men and a woman - the “sperm-competition” images - 52% of the sperm were motile. This compared with 49% sperm motility in the men who viewed the images of women only – a difference that was statistically significant after taking into account lifestyle factors such as cigarette smoking and alcohol consumption.
But there was also a seemingly contradictory finding. Men who viewed the sperm-competition images had fewer sperm in their ejaculate: 61 million per millilitre compared to 77 million per millilitre for the men who viewed the female-only images. More studies are needed to explain this finding.
“It’s a fascinating study. The effect is obviously immediate. This suggests that something [in the body] can be adjusted very, very quickly,” says Jon Evans of the University of New South Wales in Sydney, who studies sperm competition in guppy fish.
The findings might suggest ways to improve the quality of sperm during fertility treatment.
The postcoital struggle between sperm is well known in species in which females may mate with more than one partner. For example, male chickens allocate more sperm to an attractive hen with a large comb than an unattractive one, upping the chances that one of their sperm will get to the egg before those of other contenders. Bulls and boars used for artificial insemination by the farming industry produce better-quality semen if they are allowed to view other animals mating.
However, Simmons is not suggesting that humans regularly indulge in multiple matings. “We need to step away from that in 2005. The risk of sperm competition is very low nowadays, but in the lineage of primates that resulted in humans there was probably sperm competition,” he says
Previous studies have found that men who look at pornographic images depicting groups prefer the sorts of sperm-competition images used in the current study. Men may simply have evolved to find them more erotic so that they can respond appropriately to sperm competition, says Simmons.
The study, which examined the role of lifestyle factors, also suggested that carrying cellphones might be associated with lower sperm counts and a lower percentage of motile sperm. But previous studies in this area have been equivocal.

No, RoboDebbie, NO!
The news that Carnegie Mellon University now has a robotic receptionist is less impressive than the sad, dull pain behind the eyes one gets when considering the dreary inevitability of its name: "Roboceptionist." There's also some fairly horrifying information in the wire story about the backstory given the creature by four writers (and man, look how well that worked on "Viva Rock Vegas"): "Valerie... a drum-shaped contraption with a digitally animated face that appears on a computer display," wastes your time nattering on about "her boss, her psychiatrist and her dream of being a lounge star." The air of humanoid authenticity the designers were presumably going for actually breaks down right about there, because when was the last time you met a receptionist who was interested enough in you to do anything but stare vacantly at a point just off your left shoulder? I have met a few who are drum-shaped, but that's another story. Valerie seems to be intended for permanent installation at the university's computer science hall, but given the unpredictable nature of office staffing, I'd look for her to be replaced by an even more disengaged robotemp sometime this fall.

Vascular changes during penile erection in the dog.
C J Carati, K E Creed, and E J Keogh
Department of Clinical Biochemistry, Queen Elizabeth II Medical Centre, University of Western Australia.
Abstract1. The vascular effects of pelvic nerve stimulation on the penis were studied in dogs anaesthetized with sodium pentobarbitone and halothane. Changes in pressure and blood flow were measured through scalp vein needles inserted into the erectile bodies. 2. The penis contains two types of erectile body, which responded independently during erection induced by pelvic nerve stimulation. Pressure in the corpus spongiosum increased immediately upon stimulation, but only reached one-third of the more delayed pressure response of the corpora cavernosa. 3. At rest, arterial inflow resistance into the corpora cavernosa was high, whereas venous outflow resistance was low. Pelvic nerve stimulation (10-50 V, 10-16 Hz, 1 ms) caused an immediate increase in arterial flow, an increase in corpus cavernosal pressure (CCP), and a decrease in venous outflow. Saline infusion experiments showed there was active venous occlusion. Upon cessation of stimulation, these parameters returned to pre-stimulation levels. 4. The time taken to reach 50% of maximum change in arterial inflow was significantly less than for CCP, which was significantly less than for venous outflow. Occlusion of the aorta 1 min after cessation of stimulation decreased the pressure in the arterial tree supplying the corpora cavernosa, but CCP remained elevated, indicating that both inflow and outflow resistances were high. Thus, inflow resistance had returned to its pre-stimulation state before outflow resistance. 5. Direct measurements of blood flow through the corpus cavernosum were made with a hydrogen probe. There was a transient increase in blood inflow as CCP increased during pelvic nerve stimulation. There was some blood flow while CCP was elevated, indicating that the venous occlusion was not complete. 6. Sympathetic chain stimulation caused an increase in arterial resistance, and a decrease in CCP and venous resistance. 7. Infusions of acetylcholine (330 micrograms min-1) and vasoactive intestinal polypeptide (1-3.3 micrograms min-1) decreased arterial resistance and increased CCP and venous resistance. 8. This study suggests that during pelvic nerve-induced erection, arterial flow into the corpus cavernosum increases, followed by an increase in CCP and an actively controlled decrease in venous outflow.(ABSTRACT TRUNCATED AT 400 WORDS)

Chinese men swapping tiger penis for Viagra
Men's Health News
Published: Monday, 10-Oct-2005
Printer Friendly Email to a Friend
Chinese men are selectively switching from traditional Chinese medicine (TCM) to Viagra to treat erectile dysfunction, but sticking with tradition for ailments such as arthritis, indigestion and gout, according to new research published in Environmental Conservation.
The finding supports a prediction made by Australian and Alaskan researchers at the advent of Viagra's commercial release in 1998 that the new impotence drug might reduce demand for several animal species that are over-harvested to treat impotence with TCMs.
Animals such as seals, sea horses and tigers have long been hunted because practitioners of TCM use their body parts for their presumed healing and virility qualities.
The researchers surveyed 256 Chinese men, aged 50 to 76, who sought treatment at a large TCM clinic in Hong Kong. The men were questioned about their previous and current use of TCM and Western treatments for arthritis, indigestion, gout and impotence.
The study's lead authors are Dr Bill von Hippel, a psychologist from the University of New South Wales (Sydney, Australia), and his brother, Dr Frank von Hippel, a biologist from the University of Alaska, Anchorage. The von Hippels cite three key findings from the research.
"First, significantly more men had formerly used a TCM treatment for impotence than were current users," says Bill von Hippel.
"Second, they were significantly more likely to be using a Western treatment for impotence than a TCM treatment.
"Finally, among men who formerly used either Western or TCM treatments for impotence, they were more likely to switch from a TCM treatment to a Western drug than vice versa. In fact, nobody had switched from a Western drug to a TCM treatment for impotence.
"This was in contrast to their behaviour with the other three ailments - arthritis, indigestion and gout, where the men were more likely to be current users of a TCM treatment than a Western treatment.".
These findings stand in contrast to prior research suggesting a mistrust of Western medicine in Asian markets.
"When we proposed that Viagra might make inroads into TCM treatments for impotence, conservationists told us we were na? and that TCM consumers were unwilling to use a product outside their own medical tradition," says Bill von Hippel. "For example, there is still strong demand for tiger bone among TCM apothecaries who use it in the treatment of pain relief, despite the widespread availability of aspirin.
"But the failure to achieve an erection isn't comparable to having a headache or the many other ailments for which consumers still prefer TCM treatments. Furthermore, Viagra differs from many other Western drugs, in that the effects are rapid and visible to the naked eye.
"The fact is that prior to the commercial availability of Viagra in 1998, no product in any medical tradition had been proven to be an effective and non-intrusive treatment of erectile dysfunction. So despite their history of using traditional medicines and their alleged suspicions of Western medicine, the men we interviewed chose the product that works best."
These findings are consistent with previous research by the von Hippels showing evidence of a post-Viagra decline during the 1990s in the harvesting of three species used in TCM impotence treatments.
The pair attributed some of this decline to Viagra, despite scepticism among many academics and wildlife experts.
In 2002, the global market for TCM products and treatments was valued at more than $20 billion, according to the Chinese firm Shenzhen Matrix Information Consulting.

Leaving a little something extra behind after sex
Female wasp spiders are a promiscuous lot. They'll have sex with several males over the course of a breeding season.
So some of the guys sacrifice their very maleness to ensure any offspring the female has is their's. The use the tip of their own genitals as a sort of chastity belt - breaking off the member during intercourse in such a way that it plugs up the female's sexual orifice.
Giving up their genitals may help save the male's life as well. The females usually attack and kill their male partners a few seconds after sex. The detaching genitals allow for a quick get-away. Read more about this study from the Universities of Bonn and Hamburg at ScienceDaily.com.

Not At All Unusual
Lest you are tempted to believe that all of this is highly unusual and well out of the ordinary, you're in for quite a surprise. Homosexual behavior is not only common, but even more common in other species than in humans. While numbers are hard to come by, there are a few that present some interesting patterns. In ostriches, male homosexuality is much more common than bisexuality, but among mule deer, bisexuality is more common than homosexuality. Among our closest living relatives, the bonobo chimpanzees, few if any are either exclusively heterosexual or homosexual. Indeed, all that have been observed are exclusively permanently bisexual.
As for numbers, here are a few:
species percent homosexual percent bisexual percent heterosexual
silver gulls (females) 10 11 79
black headed gulls (both sexes) 22 15 63
Japanese macaques (both sexes) 9 56 35
bonobo chimpanzees (both sexes) 0 100 0
galahs (both sexes) 44 11 44
source: Bruce Bahemihl, Ph.D., Biological Exhuberance: Animal Homosexuality and Natural Diversity, St. Martin's Press, 2000, page 35
The occurence of homosexuality doesn't seem to be correlated with the predominance of a sex within a species. Some species show skewed sex ratios, but among them, homosexuality is not more common than in other species. For example, giant cowbirds and redwing blackbirds show male to female ratios as high as four to one, and in boat-tailed grackles and sparrow hawks, females predominate, but homosexuality has not been demonstrated in either species. Why is a mystery.
Homosexuality in the animal kingdom is an undeniable fact. It is as natural as can be. Since it is so common, it is therefore logical for the opponents of gay rights to try to explain it away.
Trying To Explain Away Animal Homosexuality
"Pseudo-heterosexuality." This is the favorite explanation of gay rights opponents. They claim that homosexuality in animals is the result of a shortage of, or unavailability of, heterosexual mates. There are a number of problems with this hypothesis.
First, in many species with skewed sex ratios, homosexuality is often seen more frequently in the sex which is in shorter supply rather than in the sex with a surplus of individuals.
Second, in some species where homosexual bonds form in a surplus sex, the other sex does not form homosexual bonds when it is in surplus. Humboldt penguins are an example. Males form homosexual bonds when there is a surplus of males, but females do not do so when they are in surplus.
Third, in other species, homosexual mountings occur with the same frequency regardless of whether there is a surplus, and sometimes even more frequently among balanced populations than skewed ones. Indeed, among yellow baboons, between 17% and 24% of younger individuals engage in same-sex mountings, when their sexes are roughly equal in their population, but among older yellow baboons, the males eventually outnumber the females by two-to-one, but homosexual mountings occur in only about 10% of such older individuals.
The "deprived of heterosexuality" argument. A variation on the pseudo-heterosexuality argument, this argument postulates that lower ranked males are deprived of the opportunity to mate and therefore turn to other males for sexual satisfaction.
The problem with this argument is that in many species in which harem-guarding occurs, there is no difference between higher ranking males and lower ranking ones as to the frequency of their homosexual mountings. This has been demonstrated in musk oxen, American bison, and New Zealand sea lions among others.
Among female homosexual pairs of Japanese macaques and Hanuman langurs engaging in homosexual behaviors, males approaching the pair may be threatened or even attacked.
When homosexual bonding does occur in the absence of opposite sex pairs, members of such a pair often resist attempts to 'convert' them back into heterosexual relationships. Even when deprived of their bonded partner, white-fronted Amazon parrots will not revert, and long-eared hedgehogs have refused heterosexual partners for as long as two and a half years, much of their natural lifetime. In the case of Stellar's sea eagles and female barn owls, both housed without opposite sexed members of their species, homosexual pair bonds among females were strong enough that when inseminated, they coparented the chicks that resulted.
Homosexual bonds can be tight. Among male rhesus macaques, crab-eating macaques, bottlenosed dolphins, cheetahs and black-headed gulls with homosexual bonded partners, the members of the pair exhibited considerable distress at being separated from their partners. In all cases, the individuals ignored opposite sex partners offered them, and showed considerable joy and exhuberance at the reintroduction of their partners.
The "Mistaken Identity" hypothesis. This one seeks to explain animal homosexuality by claiming that the same sex partner is 'confused' and unable to identify a member of the opposite sex.
The problem here is that in some animals, the difference between sexes are obvious. Vastly different body color, shape or size are an obvious clue, yet in these species, homosexual bonds still form, even when body shape precludes easy homosexual mounting.
Another problem with this hypothesis is the fact that homosexual couples often engage in very different courtship rituals than do heterosexual couples. If it were a case of mistaken identity, how would this happen? In the case of bisexual animals, it has been seen that one set of courtship rituals are used by the same individual when courting homosexual versus heterosexual partners. This would not happen if the problem were a case of mistaken identity.
The "Gross Abnormalities of Behavior" hypothesis. The assumption here is that the behavior is a manifestation of a disease process.
Scientists looking into this hypothesis often examine animals for genital abnormalities, on the assumption that there is some kind of hormonal imbalance. The fact is that they rarely ever find abnormalities, never with enough frequency for it to be statistically meaningful. That's because of the mistaken assumption by some scientists that homosexuality is some sort of hermaphroditic condition. It's not, and that's why they never find what they're looking for.
If homosexuality were a manifestation of a disease process, why is homosexuality observed in roughly the same degree in captive populations versus wild populations, or in diverse wild populations? Whatever would be causing the disease cannot be equally present in all cases, both in the field and in the wild, so differences in occurrence should show up. But they rarely do. Why?
The "population control" hypothesis. The problem with this one is that field observations directly counter it. It has been observed in ochre-bellied flycatchers and ruffed grouse populations among others, that even when opposite sex partners, territories and breeding grounds are all available, some individuals still form homosexual bonds, and the ratio by which they do rarely differs even when the population is under stress.
Something's Not Quite Right At The Zoo
Critics of this research like to point out that if homosexuality actually existed in animals, it would have been observed in zoos. Well, it has been, and for as long as zoos have been kept.
Zoo keepers who have observed this behavior historically ascribed it to the presence of stressors that exist in zoos that are not present in the wild. That was always the assumption. Such factors as same-sex isolation. Lack of stimulating activities. Unnatural living quarters. Unnatural diet. Then when field reports of similar behaviors started coming in, the existence of homosexuality in animals became to great to ignore. Today, animal behaviorists are unanimous in accepting the fact of animal homosexuality.
There's clearly a wide range of homosexual behaviors in the animal kingdom. It's widespread, common and impossible to deny or explain away any longer. Homosexuality is natural as green grass in summer, and it's high time we accepted that fact.
The birds do it. It's been described in 130 species of birds. The southeastern blueberry bees do it. Same sex pairs of animals kiss and caress each other with obvious affection and tenderness. Male pairs and female pairs form long-lasting pair-bonds and reject, threaten, even fight off potential opposite sex partners when they are presented with them. Same sex partners engage in almost every conceivable means of sexual expression throughout the animal kingdom.
It's high time we quit criminalizing something that is so normal, so natural, so harmless and so common among animals and recognize that what we call "sodomy" is really quite natural after all.

Introduction. Penile augmentation surgery has become increasingly common though there is no consensus about the management strategy for men with a complaint of small penis. Aim. To introduce and evaluate the outcome of a structured management and counseling protocol for patients with a complaint of a small-sized penis. Methods. A structured protocol for consultation and management of (physically normal) patients with a complaint of a small penis through a descriptive study comprised of a series of 250 patients. Main Outcome Measures. Percentage of patients who elect to undergo penile augmentation surgery. Results. Only nine patients (3.6%) chose to seek further surgical intervention. Two had a buried penis, two had true micropenis and five had normal penile size. Conclusions. Using a structured management and counseling protocol, most men chose not to undergo penile augmentation surgery, even when offered for free.

Shared parentage and incest avoidance in the cooperatively breeding acorn woodpecker.Haydock J, Koenig WD, Stanback MT.
Department of Biology, Gonzaga University, 502 E. Boone Ave., Spokane, WA 99258, USA. [email protected]
Social groups of acorn woodpeckers (Melanerpes formicivorus) range in size from unaided pairs to 15 adults. Behavioural indicators of mate guarding, assumed incest avoidance and observations of egg-laying indicate that social organization ranges from monogamous pairs to groups with up to seven male and three female putative cobreeders plus up to 10 nonbreeding helpers. In addition, groups occasionally lack a putative breeder throughout the breeding season. Here we report results from multilocus DNA fingerprinting of 372 nestlings from 123 nests in groups with putative cobreeders of one or both sexes. No extra-group fertilizations were found. Putative cobreeding males within social groups shared paternity. However, the most reproductively successful male was, on average, almost three times as successful as the next most successful and additional males only occasionally sired offspring. In contrast, cobreeding females shared parentage equally. Helpers never bred incestuously when their opposite-sex parent (or another relative, such as their uncle) held breeding status in the group. However, during breeding male vacancies, 14 nestlings were produced when helper males bred incestuously with their mother. Both male and female helpers usually became successful cobreeders with their same-sex parent following replacement of the opposite-sex breeder(s) by unrelated individuals.

Behavioral treatment of zoophilic exhibitionism.McNally RJ, Lukach BM.
Department of Psychology, Harvard University, Cambridge, MA 02138.
We describe here a case of zoophilic exhibitionism involving a mildly mentally retarded man who masturbated in front of large dogs of either sex. Unlike most exhibitionists, he did not expose himself to women, and unlike most zoophiles, he never desired direct sexual contact with animals. His paraphilia, however, was responsive to a behavioral program comprising masturbatory satiation, covert sensitization, and stimulus control procedures.

Imipramine-induced erection, masturbation, and ejaculation in male horses.McDonnell SM, Garcia MC, Kenney RM, Van Arsdalen KN.
Imipramine hydrochloride was administered to five male horses (400-500 kg b.wt.): one experienced young stallion, two mature normal breeding stallions, one 5-year-old stallion with erection and ejaculatory dysfunction, and one long-term castrated male horse. Oral imipramine treatment (100 to 600 mg, twice daily) led to frequent erection and masturbation while at rest in the stall in a nonsexual context. Intravenous imipramine treatment over a range of doses (50 to 1000 mg) similarly induced erection and masturbation in all animals. Erection typically occurred within 10 minutes after injection, and the erection and masturbation continued intermittently for 1 to 2 hours. These erections proceeded as during sexual excitement to a normal firmness and eventual engorgement of the glans penis. Two stallions ejaculated while masturbating. Mild ataxia and drowsiness appeared at the higher doses, but the animals remained responsive to auditory, visual, and tactile stimuli. Erection and masturbation were often interrupted by activities about the barn or the approach of the handler, suggesting cortical inhibitory control of the erection. When tested in a sexual context immediately following IV treatment (500 mg), the two mature breeding stallions bred normally. The 5-year-old stallion, which had not ejaculated over several months of breeding attempts, spontaneously ejaculated following IV imipramine treatment. Subsequently, this stallion has ejaculated during copulation while on low dose oral (100 mg. twice daily) imipramine treatment. Plasma total androgens increased during treatment in these stallions. The long-term castrate showed erection and masturbation following IV imipramine treatment, suggesting that the effect of imipramine is not testosterone dependent.

Materials and Methods
References AbstractExperimental allergic encephalomyelitis (EAE) and multiple sclerosis (MS) are characterized by strong sexual dimorphisms, many of which may be due to genetically controlled sex hormone effects on the immune system, the central nervous system (CNS), or both. In the present study we used 487 gonadectomized and 376 intact age-matched F2 mice generated through crosses of B10.S/SgMcdJ and SJL/J mice to assess the role of adult gonadal hormones in regulating clinical and histopathological quantitative traits (QT) associated with EAE in the context of genetic heterogeneity. We found that gonadectomy resulted in different effects, depending on the QT and the sex of the mouse. Ovariectomized mice on average had lower cumulative clinical disease scores, shorter duration of clinical signs, and increased peak disease scores. This trend was accompanied by a significant increase in the incidence of acute, progressive EAE which is more frequently seen in intact and orchiectomized males. Although spinal cord (SC) inflammation was the better predictor of clinical signs of EAE in both sexes, ovariectomized females had considerable reductions in nearly all histopathological QT in both the brain and SC. Orchiectomy resulted in modestly significant increases in disease severity and peak score and earlier onset of clinical signs. With the exception of SC demyelination and lesion scores, orchiectomy had no effect on histopathological QT. Importantly, gonadectomy reduced but did not completely abolish any of the sexually dimorphic clinical QT seen in intact mice. It did however, lead to a significant sexual dimorphism in incidence and severity not seen in intact mice. For histopathological QT, no sexual dimorphism was detected for brain lesions in either intact or gonadectomized mice. In contrast, SC histopathological QT exhibited significant sexual dimorphisms, which were impacted by gonadectomy. The results from this study indicate that within the context of genetic heterogeneity, circulating gonadal hormones influence both clinical and histopathological QT in this model of MS, but they do not solely account for the sexual dimorphisms seen in these traits. Thus, additional mechanisms must play a role in regulating gender differences in autoimmune disease of the CNS.

Prestigious Medical Journal Discovers New Use for Duct Tape
Under the category of "strange but true", according to the October 2002 issue of the Archives of Pediatric and Adolescent Medicine, research has shown that duct tape is more effective at removing warts than standard medical treatment. The study was conducted at the Madigan Army Medical Center near Tacoma, Washington. In the research 51 patients with warts between the ages of 3 and 22 were studied. One group received standard medical treatment for warts (cryotherapy) which consisted of liquid nitrogen applied to each wart for 10 seconds every 2-3 weeks for a maximum of 6 treatments. The other group had duct tape applied directly to the wart for a maximum of 2 months.
The results showed that of the 51 patients completing the study, 26 (51%) were treated with duct tape, and 25 (49%) were treated with cryotherapy. Twenty-two patients (85%) in the duct tape group vs 15 patients (60%) enrolled in the cryotherapy group had complete resolution of their warts. The researchers stated the obvious in their conclusion, "Duct tape occlusion therapy was significantly more effective than cryotherapy for treatment of the common wart."
According to lead researcher Dr. Dean "Rick" Focht III of Cincinnati Children's Hospital Medical Center, the duct tape irritated the warts, which apparently caused an immune system reaction that attacked the growths. He said researchers did not test other kinds of tape, and so they cannot say whether there is anything special about the gray, heavy-duty, fabric-backed tape.
The report in the journal did mention that there had been some reports of occlusion therapy (tape) for warts in the past. But there was no mention of why duct tape specifically was chosen for the study. Several comedians including Tim Nyberg, one-half of the comedy duo, "Duct Tape Guys" are having a field day with this latest research. "It's the universal panacea," Nyberg said.

I nominate myself for the win because "penguin semen" is really near and dear to my heart. That was a study that had to be done for the greater good of mankind. Basically, by me posting it, I have changed the world as we know it.
(Actually, Im freaking addicted to RPM and Im saying its the best supplement Ive ever used and thats after DAY 6, so whether it's free or night, ugab will have a massive stockpile of RPM)

I still havent got my sample but based on the sample of igf I got I am excited to get me some RPM.....or anything from AN

A serological and fecal parasitologic survey of the critically endangered pygmy raccoon (Procyon pygmaeus).McFadden KW, Wade SE, Dubovi EJ, Gompper ME.

The pygmy raccoon (Procyon pygmaeus) of Cozumel Island, Mexico, is among the most endangered carnivores in the world, and causes of its decline are unclear. During 2002 and 2003, we sampled approximately 10% of the remaining population to survey exposure to viral and parasitic pathogens that may have contributed to population decline. We found evidence of exposure to infectious canine hepatitis, canine distemper, feline panleukopenia virus, and Toxoplasma gondii. The latter is suggestive of spillover from domestic cats, which have only recently been introduced to the island. Additional parasites identified include Eimeria nutalli, Placoconus lotoris, Capillaria procyonis, Physaloptera sp., a mite in the family Listrophoridae, and a trematode in the family Heterophyidae. Several of these are typical of the parasite community of the common raccoon (Procyon lotor).
