Investigators even suspected that the difficulties experienced by teams in mammal-cloning experiments were due to the absence of RNAs in the sperm. In cloning, scientists would take the DNA from a non-germ cell, add it to an egg denuded of its DNA and trick it into developing as though it were fertilized by a sperm. The procedure would work only a few times. Most of the time, it would develop gross defects, which often delayed further development. John Eppig, a reproductive biologist at Jackson Laboratory in Bar Harbor, Maine, suggested that the success of cloning was a strong argument against the supposed key biological role of apparently large numbers of RNAs being delivered by the sperm (Travis).
It has been estimated that infertility occurs in 2 million couples in the United States (American Family Physician 1993). About a third of these are attributed to male factors, including primary testicular failure, secondary testicular failure and post-testicular obstruction.
Greendale and his colleagues conducted a study on the possibility of Chlamydia trachomatis as another cause of unexplained infertility. In the study, the team utilized 52 men who were diagnosed with explicitly defined idiopathic infertility and were enrolled in two infertility practices as one group. The other group consisted of 79 men who were enrolled in prenatal classes their partners. Those couples who had unprotected intercourse were placed in a group, which was subjected to two semen analyses. These respondents were not hypogonadal or azoospermic and their partners had idiopathic primary or secondary infertility. When their serum IgG anti-Chlamydia antibodies were measured, infertile men were found to be 3.4 times more likely than fertile men to have a higher titer. About 50% of patients in both groups with anti-Chlamydia antibody titers of 1:64 or higher had no symptoms of infection. Among asymptomatic patients, 20% exhibited abnormal penile discharge, 205 with non-traumatic testicular swelling or pain, and 40% with dysuria. However, these findings by Greenpeace and his team were later found to be inconclusive (American Family Physician).
Pain Syndrome
Researchers at Mayo Clinic announced that those who suffer from fibromyalgia could be helped by acupuncture (Health News 2006). Their study on 50 patients who suffered from symptoms like fatigue and anxiety found that they obtained relief from the method. The added advantage was that acupuncture has few side effects. The results of its experiments led Mayo Clinic to speculate that this ancient therapy might possess benefits. Previous researches suggested that acupuncture possibly stimulates pain-killing substances in the body or alters brain chemistry. This, in turn, affects areas of the central nervous system involved in pain sensation and other involuntary functions (Health News).
Data from a large German research effort offered support for the use of acupuncture in treating chronic pain conditions (Walsh 2005). The study was sponsored by the country's insurance companies. The data derived from two reports from the Acupuncture in Routine Care study, which were presented during a symposium on alternative and complementary therapies, and sponsored by the Universities of Exeter and Plymouth. The reports presented and demonstrated statistically significant and clinically relevant benefits of acupuncture when used in addition to routine care for headache and neck pain. It utilized 15,056 patients with migraine or tension-type of headaches. They were allocated up to 15 acupuncture treatments at random during a three-month period in combination with conventional treatment by analgesics. A control group was also used, which received conventional treatment only. A third group consisted of patients who did not agree to random acupuncture treatment was also used and monitored. About 75% of them were female with 44 years as the mean age. In the group, 3,182 agreed to randomization, 1,613 were in the acupuncture group, and 1,569 in the control group. After the three months of treatment, the volunteers reported that the frequency of their headache days per month had decreased. The incidence went down significantly from 8.4 days to 4.7 days in the acupuncture groups, greater than the reduced level in the control group. Headache types were also recorded. Those with migraine had an average of 7 days per month of the episodes before treatment and four days per month after treatment, which included acupuncture. Those with tension headaches also decreased from an average of 10 days per month to only 5 days per month (Health News).
The tabulated improvements persisted in the succeeding three months (Health News 2006). In the control group, 70% of the patients needed complementary treatment with analgesics, as compared with 50% of those in acupuncture groups. This was the finding of the first report. The second report on the study of the effect of acupuncture on neck...
break out of war in Afghanistan and Iraq propelled alarming forecasts about its most likely psychiatric effects. The chief of recuperation or readjustment therapy services at the Department of Veterans Affairs (VA) asserted that as high as 30% of soldiers deployed to Iraq may establish posttraumatic tension ailment (PTSD) (Dentzer, 2003), a disorder that can arise following experience of gruesome, dangerous occasions, such as battle, natural catastrophes, and rape.
Veterans & Retirees; Is Government Keeping its Promise This study aimed at exploring the experiences and perceptions of Veterans belonging to Lousiana and Mississippi about three variables; the accessibility of organization; the accessibility of benefits and availability and adequacy of the facilities being provided by government through VA. The respondents were also asked to suggest whether there is a need for improvement and what should VA do to provide benefits and

Recovery Plan: Biological Attack in the U.S. Congress The havoc and deaths caused by the weaponized anthrax spores that were mailed to members of the U.S. Congress following the attacks of September 11, 2001 and the repeated attempted uses of botulinum toxin on U.S. Naval bases make it abundantly clear that governmental offices are vulnerable to biological pathogens. These agents have been and likely will be used by terrorists again
Air traffic has continued to increase and it now constitutes a considerable proportion of the travelling public. The amount of long-hour flights has increased significantly. Based on the International Civil Aviation authority, air traffic can be anticipated to double amid till 2020. Airline travel, especially over longer distances, makes air travelers vulnerable to numerous facets that will impact their health and well-being. Particularly, the speed with which influenza spreads and
Adolescent Substance Use Screening Instruments: 10-Year Critical Review of the Research Literature Over ten million teenagers in the United States admit in a national survey that they drink alcohol, although it is illegal under the age of 21 in all states. In some studies, nearly one-quarter of school-age children both smoked cigarettes and drank alcohol. Over four thousand adolescents every day try marijuana for the first time. The dangers of use,
