Early-onset puberty in females explained Posted: 29 Jan 2013 10:09 AM PST This research provides significant insight into the reasons why early-onset puberty occurs in females. The researchers located key genes that trigger puberty and highlighted how external forces (epigenetics) appear to be a possible cause of early-onset puberty in some cases. |
Posted: 29 Jan 2013 10:09 AM PST The risk of future cardiovascular disease and death increased with severity of erectile dysfunction in men both with and without a history of cardiovascular disease. While previous studies have shown an association between ED and CVD risk, this study finds that the severity of ED corresponds to the increased risk of CVD hospitalization and all-cause mortality. |
Beer's bitter compounds could help brew new medicines Posted: 29 Jan 2013 10:08 AM PST Researchers using a century-old technique have determined the precise configuration of substances from hops that give beer its distinctive flavor. That could lead to formulation of new pharmaceuticals to treat diabetes, some cancers and other ailments. |
Hydrogen sulfide: The next anti-aging agent? Posted: 29 Jan 2013 09:19 AM PST Hydrogen sulfide may play a wide-ranging role in staving off aging, according to a new article. In this review article, a team from China explores the compound's plethora of potential anti-aging pathways. |
Gene found that turns up effect of chemotherapy Posted: 29 Jan 2013 09:19 AM PST Chemotherapy is one of the most common treatments for cancer patients. However, many patients suffer from serious side-effects and a large proportion does not respond to the treatment. Researchers now show that the gene FBH1 helps turn up the effect of chemotherapy. |
'Master' proto-oncogene regulates stress-induced ovarian cancer metastasis Posted: 29 Jan 2013 09:18 AM PST Scientists have discovered the signaling pathway whereby a master regulator of cancer cell proteins -- known as Src -- leads to ovarian cancer progression when exposed to stress hormones. The researchers report that beta blocker drugs mitigate this effect and reduce cancer deaths by an average of 17 percent. |
Attitudes toward HPV vaccination for boys Posted: 29 Jan 2013 08:17 AM PST A new study has found that low-income and minority parents/guardians were receptive toward vaccinating boys against Human Papilloma Virus. However, racial/ethnic differences emerged in attitudes regarding school-entry mandates. |
Better way to culture central nervous cells Posted: 29 Jan 2013 08:17 AM PST A protein associated with neuron damage in Alzheimer's patients provides a superior scaffold for growing central nervous system cells in the lab. The findings could have clinical implications for producing neural implants and offers new insights on the complex link between the apoE4 apolipoprotein and Alzheimer's disease. |
Indoor air puts Chinese women nonsmokers at risk Posted: 29 Jan 2013 08:17 AM PST The hazards of breathing outdoor air in some Chinese cities have been well-documented. Now a study confirms that breathing indoor air also carries significant cancer risks, especially for Chinese women. |
Posted: 29 Jan 2013 07:02 AM PST Mice with decreased activity of a protein complex involved in mitochondrial function exhibit reduced body weight and decreased fat mass, and their media life span is 20 percent longer. This intrigues scientists. |
Epigenetic control of cardiogenesis Posted: 29 Jan 2013 07:02 AM PST Scientists have now been able to demonstrate that non-coding RNA is essential for normal embryonic cardiogenesis. |
New insights into conquering influenza Posted: 29 Jan 2013 07:02 AM PST Researchers have discovered a new protein that protects against viral infections such as influenza. |
Taking the stairs, raking leaves may have same health benefits as a trip to the gym Posted: 29 Jan 2013 07:01 AM PST New research suggests the health benefits of small amounts of activity – even as small as one- and two-minute increments that add up to 30 minutes per day – can be just as beneficial as longer bouts of physical exercise achieved by a trip to the gym. |
Diabetes drug could hold promise for lung cancer patients Posted: 29 Jan 2013 07:01 AM PST Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, one medical researcher has wondered if drugs originally designed to treat metabolic diseases could also work against cancer. |

A step towards repairing the central nervous system Posted: 29 Jan 2013 05:02 AM PST Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation. |
Early menopause may occur in women with BRCA gene Posted: 29 Jan 2013 04:44 AM PST Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a new study. |
Health benefits of coming out of the closet demonstrated Posted: 29 Jan 2013 04:44 AM PST Lesbians, gays and bisexuals (LGBs) who are out to others have lower stress hormone levels and fewer symptoms of anxiety, depression, and burnout, according to researchers. Cortisol is a stress hormone in our body. When chronically strained, cortisol contributes to the 'wear and tear' exerted on multiple biological systems. |
Debunking the ‘July Effect’: Surgery date has little impact on outcome Posted: 29 Jan 2013 04:44 AM PST The "July Effect" -- the notion that the influx of new residents and fellows at teaching hospitals each July makes that the worse time of year to be a patient -- seems to be a myth, according to new research that examined nearly 1 million hospitalizations for patients undergoing spine surgery from 2001 to 2008. Among those going under the knife, researchers discovered that the month surgery occurred had an insignificant impact on patient outcomes. |
