Their study is published online in ACS' monthly journal Chemical Research in Toxicology. http://www.physorg.com/news179052113.html Chemistry Thu, 03 Dec 2009 09:30:03 EST news179052113 High-frequency ultrasound with elastography can help differentiate between cancerous and benign skin conditions, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://www.physorg.com/news178867687.html Medicine & Health Tue, 01 Dec 2009 05:50:02 EST news178867687 Elastography is an effective, convenient technique that, when added to breast ultrasound, helps distinguish cancerous breast lesions from benign results, according to an ongoing study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://www.physorg.com/news178786052.html Medicine & Health Mon, 30 Nov 2009 08:50:02 EST news178786052 Researchers at Ben-Gurion University of the Negev are developing a new device that detects cancerous skin tumors, including melanomas that aren't visible to the naked eye. http://www.physorg.com/news178279858.html Medicine & Health Tue, 24 Nov 2009 10:40:02 EST news178279858 Over 300 million patients use non-steroidal anti-inflammatory drugs (NSAIDs) in the world to treat pain, arthritis, fever and other diseases. Nearly 30% of the users suffer from gastric lesions and bleeding. To mitigate NSAIDs' adverse effects on the stomach, misoprostol, a non-selective prostaglandin E1 (PGE1) analogue, has been prescribed as the first choice for prevention of NSAID-induced injuries, but often induces severe adverse effects. There remain unmet medical needs for drugs with improved therapeutic profiles. http://www.physorg.com/news177764423.html Medicine & Health Wed, 18 Nov 2009 17:00:03 EST news177764423 The saying "more pain, more gain" may be true for those already in terrible pain due to a chronic and debilitating condition, contrary to received wisdom. For those with Type I Complex Regional Pain Syndrome (CRPS), working through the pain of an aggressive physiotherapy program often leads to far better results than a more cautious pain-free approach. That was the result of a new study in Clinical Rehabilitation, published this week by SAGE. In fact, nearly half those who were given the painful treatment recovered normal physical function, whereas those who avoided painful physiotherapy usually had further loss of physical function. http://www.physorg.com/news177257195.html Medicine & Health Thu, 12 Nov 2009 14:50:05 EST news177257195 Human papillomavirus (HPV) DNA testing with cytology triage is more sensitive than conventional cytology screening for detecting cervical lesions, according to a new study published online November 9 in the Journal of the National Cancer Institute.

In one step, a physician can find precancerous lesions in the colon and then cut them out, an on-the-spot intervention that prevents cancer from developing. Now, researchers at the Winthrop Rockefeller Cancer Institute and the University of Arkansas for Medical Sciences have developed another fiber optic technique that can detect lymph node metastases and destroy them on the spot, an action that could prevent the further spread of breast cancer, melanoma, or gastrointestinal cancer, all of which spread through the lymphatic system. http://www.physorg.com/news176116481.html Nanotechnology Fri, 30 Oct 2009 10:15:06 EST news176116481 A Swiss research team has found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions and restoring function. http://www.physorg.com/news176014548.html Medicine & Health Thu, 29 Oct 2009 05:56:51 EST news176014548 Heparin, a commonly used anticoagulant, can cause skin lesions, reports a study in CMAJ (Canadian Medical Association Journal). Skin lesions caused by heparin may indicate the presence of a life-threatening decrease in the number of platelets, a condition called "heparin-induced thrombocytopenia" or a, in most cases self-limiting, allergic skin reaction. http://www.physorg.com/news173363046.html Medicine & Health Mon, 28 Sep 2009 13:40:01 EST news173363046 Yes-associated protein (YAP) is a type of cellular adaptor protein and transcriptional co-activator. In recent years, some investigators have found YAP to be overexpressed and highly activated in hepatic cancers and mammary cancers, suggesting its tumorigenicity. Survivin is a new member of the inhibitor of apoptotic protein (IAP) family, which was initially cloned by the cDNA of the effector cell protease receptor-1 in the human genomic library in 1997. http://www.physorg.com/news172329086.html Medicine & Health Thu, 17 Sep 2009 02:20:01 EST news172329086 The intraductal papillary mucinous neoplasms (IPMN) can evolve through all biological stages, from slight dysplasia to carcinoma. As one of the few surgically curable pancreatic tumors, accurate preoperative prediction of malignancy remains one of the major issues in the optimal treatment of IPMNs, and it also influences the outcome of the resection. http://www.physorg.com/news172311550.html Medicine & Health Wed, 16 Sep 2009 09:30:01 EST news172311550 In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology have pinpointed the brain structure responsible for our sense of personal space. http://www.physorg.com/news170862623.html Medicine & Health Sun, 30 Aug 2009 14:51:08 EST news170862623 (PhysOrg.com) -- People with psoriasis - an often distressing dermatological condition that causes lesions and red scaly patches on the skin - are less likely to react to looks of disgust by others than people without the condition, new research has found. http://www.physorg.com/news170597428.html Medicine & Health Thu, 27 Aug 2009 13:19:23 EST news170597428 Serrated colorectal polyps include the subgroups hyperplastic polyps, sessile serrated polyps (also called sessile serrated adenomas), and serrated adenomas. Recent studies have found that serrated polyps share molecular features with a subgroup of colon cancers, leading to the hypothesis that serrated polyps can be precursors of cancer through a hyperplastic polyp to serrated adenoma to cancer sequence. These cancers tend to arise in the proximal colon. Sessile serrated polyps may be an intermediate step between hyperplastic polyp and serrated adenomas. http://www.physorg.com/news170420666.html Medicine & Health Tue, 25 Aug 2009 12:30:02 EST news170420666 Breast MRI allows physicians to evaluate suspicious lesions using a variety of variables.

About 60 percent of untreated individuals develop arthritis, which affects the knees in particular. Lyme disease usually responds well to antibiotic therapy, but in rare cases arthritis can persist for months or years after treatment, a rare condition known as antibiotic-refractory Lyme arthritis. Joint fluid usually tests negative for B burgdorferi after treatment, indicating that joint inflammation may persist even after the bacteria has been eradicated. http://www.physorg.com/news165597953.html Medicine & Health Tue, 30 Jun 2009 16:26:18 EST news165597953 A University of Wisconsin-Madison biomedical engineer and colleagues have developed a method that, applied in MRI scans of the breast, could spare some women with increased breast cancer risk the pain and stress of having to endure a biopsy of a questionable lump or lesion. http://www.physorg.com/news165498403.html Medicine & Health Mon, 29 Jun 2009 13:00:02 EST news165498403
