It's not the most serious physical problem in our lives, but it is common and it is very annoying. Now, researchers at the Hebrew University of Jerusalem and in Boston have come up with new findings that can stop the itching through silencing the neurons that transmit itch-generating stimuli. http://medicalxpress.com/news/2013-06-scientists.html Neuroscience Wed, 05 Jun 2013 10:53:51 EST news289648422 A known difficulty in fighting influenza (flu) is the ability of the flu viruses to mutate and thus evade various medications that were previously found to be effective. Researchers at the Hebrew University of Jerusalem have shown recently that another, more promising, approach is to focus on improving drugs that boost the body's natural flu killer system. http://medicalxpress.com/news/2013-05-boosting-body-natural-flu-killers.html Diseases, Conditions, Syndromes Thu, 23 May 2013 11:06:47 EST news288525999 A new study conducted using extensive medical records of over one million Israeli adolescents before military service shows clearly how exposure to the Israeli sun of young, light-skinned children increases substantially the risk of cutaneous melanoma (a serious form of skin cancer). http://medicalxpress.com/news/2013-05-young-israelis-emphasizes-sun-exposure.html Cancer Mon, 20 May 2013 07:10:42 EST news288252635 A mechanism that permits essential substances to enter our cells while at the same time removing from them harmful components also has a "down side." This negative aspect prevents vital drugs, such as anti-cancer drugs, from achieving their designed functions, while also enabling bacterial cells to develop resistance to penetration of antibiotics. http://medicalxpress.com/news/2013-05-traffic-cells.html Medical research Wed, 01 May 2013 10:21:02 EST news286622453 The same factor in our immune system that is instrumental in enabling us to fight off severe and dangerous inflammatory ailments is also a player in doing the opposite at a later stage, causing the suppression of our immune response. http://medicalxpress.com/news/2013-04-probe-enigma-element-enemy.html Immunology Wed, 03 Apr 2013 10:01:53 EST news284202106 Researchers at the Hebrew University of Jerusalem, in collaboration with researchers at the Salk Institute in California, have found for the first time that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular and nervous systems, as well as in various cancers. http://medicalxpress.com/news/2013-01-specific-protein-essential-healthy-eyes.html Neuroscience Mon, 07 Jan 2013 07:53:08 EST news276767582 All living cells keep their cellular calcium concentration at a very low level. Since a small increase in calcium can affect many critical cellular functions (an elevated calcium concentration over an extended period can induce cell death), powerful cellular mechanisms ensure that calcium concentration quickly returns to its low level. http://medicalxpress.com/news/2013-01-key-mechanism-calcium.html Neuroscience Thu, 03 Jan 2013 10:16:08 EST news276430561 A new understanding of what takes place on the cellular level during the development of neurodegenerative diseases, such as Parkinson's, Alzheimer's, ALS and Huntington's diseases, offers promise towards possible new strategies for combating such diseases, say Hebrew University of Jerusalem researchers. http://medicalxpress.com/news/2012-12-srategies-neurodegenerative-diseases.html Medical research Thu, 06 Dec 2012 10:44:36 EST news274013065 (Medical Xpress)—More than a million people die each year of malaria caused by different strains of the Plasmodium parasite transmitted by the Anopheles mosquito. The medical world has yet to find an effective vaccine against the deadly parasite, which mainly affects pregnant women and children under the age of five. By figuring out how the most dangerous strain evades the watchful eye of the immune system, researchers from the Hebrew University of Jerusalem have now paved the way for the development of new approaches to cure this acute infection. http://medicalxpress.com/news/2012-12-deadly-malaria-parasite-evades-immune.html Medical research Mon, 03 Dec 2012 08:58:30 EST news273747380 If you think that you can judge by examining someone's facial expressions if he has just hit the jackpot in the lottery or lost everything in the stock market—think again. Researchers at the Hebrew University of Jerusalem and at New York University and Princeton University have discovered that—despite what leading theoretical models and conventional wisdom might indicate—it just doesn't work that way. http://medicalxpress.com/news/2012-11-body-language-facial.html Psychology & Psychiatry Thu, 29 Nov 2012 14:58:38 EST news273423511 (Medical Xpress)—A newly-engineered strain of mice whose dividing cells express a fluorescent protein could open the door to new methods of regulating cell proliferation in humans. Cell proliferation plays a key role in degenerative diseases, in which specific cells do not replicate enough, and in cancers, in which cells replicate too much. http://medicalxpress.com/news/2012-11-cell-proliferation-key-factor-degenerative.html Medical research Wed, 28 Nov 2012 07:51:58 EST news273311505 (Medical Xpress)—An experimental diet with carbohydrates eaten mostly at dinner could benefit people suffering from severe and morbid obesity, according to new research at the Hebrew University of Jerusalem. http://medicalxpress.com/news/2012-11-limiting-carbs-dinner-time-satiety-diabetes.html Health Thu, 08 Nov 2012 08:17:05 EST news271584986 Common wisdom has it that if the visual cortex in the brain is deprived of visual information in early infanthood, it may never develop properly its functional specialization, making sight restoration later in life almost impossible. http://medicalxpress.com/news/2012-11-mind-eye-scientists.html Neuroscience Wed, 07 Nov 2012 12:00:07 EST news271506734 (Medical Xpress)—New research from the Hebrew University of Jerusalem shows that a carefully scheduled high-fat diet can lead to a reduction in body weight and a unique metabolism in which ingested fats are not stored, but rather used for energy at times when no food is available. http://medicalxpress.com/news/2012-09-carefully-high-fat-diet-resets-metabolism.html Overweight and Obesity Wed, 12 Sep 2012 07:20:06 EST news266653153 A synthetic, anti-inflammatory and anti-allergic family of drugs to combat a variety of illnesses while avoiding detrimental side effects has been developed by a Hebrew University of Jerusalem researcher. http://medicalxpress.com/news/2012-09-multi-functional-anti-inflammatoryanti-allergic.html Inflammatory disorders Thu, 06 Sep 2012 11:20:33 EST news266149213
