However, little was previously known about what specific compounds and biochemical interactions in the fruit contribute to its medical and nutritional benefits such as weight loss and prevention of type 2 diabetes. A Virginia Tech research team discovered that the olive-derived compound oleuropein helps the body secrete more insulin, a central signaling molecule in the body that controls metabolism. The same compound also detoxifies another signaling molecule called amylin that over-produces and forms harmful aggregates in type 2 diabetes. In these two distinct ways, oleuropein helps prevent the onset of disease. The findings were recently published in the journal   Biochemistry  a s a Rapid Report, which is reserved for timely topics of unusual interest, according to the journal. "Our work provides new mechanistic insights into the long-standing question of why olive products can be anti- diabetic," said Bin Xu, lead author, assistant professor of biochemistry in th...

Asthma is a common and long-term condition affecting around one in ten people in the western world. The majority of patients rely on daily medicine to control symptoms and many are wary of exercise, fearing that it could induce symptoms. However, the new research suggests that taking exercise, combined with a healthy diet, could help patients gain better control of symptoms such as wheezing, chest pain and shortness of breath. The research was presented by Dr Louise Lindhardt Toennesen (MD, PhD) from Bispebjerg University Hospital, Copenhagen, Denmark. She told the congress: "There is increasing evidence that asthma patients who are obese can benefit from a better die t and increased exercise. We wanted to see if non-obese patients with asthma could also benefit." Dr Toennesen and her colleagues worked with a group of 149 patients who were randomly assigned to one of four groups. One group were asked to follow a diet that was high in protein and with a low glycaemic...

The research group of Professor Masaharu Noda, Associate Professor Takafumi Shintani, and a graduate student Satoru Higashi of the National Institute for Basic Biology (NIBB) demonstrated that protein tyrosine phosphatase receptor type J (PTPRJ) inhibits leptin signaling and that induction of PTPRJ in the hypothalamus is a cause of leptin resistance. They showed that Ptprj is expressed in hypothalamic neurons together with leptin receptors, and that PTPRJ inhibits activation of the leptin receptor through dephosphorylation of JAK2, a protein tyrosine kinase associated with the leptin receptor. Ptprj-deficient (Ptprj-KO) mice showed no growth retardation, but exhibited lower weight gain, because of a lower food intake and a lower adiposity, than wild-type (WT) mice. Importantly, PTPRJ expression in the hypothalamus was up-regulated by diet-induced obesity , and, thus, diet-induced leptin resistance did not occur in Ptprj-KO mice. Furthermore, the overexpression of PTPRJ in th...

That is an overlay of great constructive correlation of rCGM with WHtR in prodromal/early AD (n = 34) and CN (n = 55) adjusted for age, intercourse, and schooling. Coloration overlays present comparability of correlation of rCGM with WHtR between prodromal/early AD (pink coloration overlay) and CN (inexperienced coloration overlay). rCGM, regional cerebral glucose metabolism; WHtR, waist to top ratio; AD, Alzheimer's illness; CN, cognitively regular.

Clinics that treat STIs and community-based clinics serving men who have sex with men (MSM) are promising sites to deliver preexposure prophylaxis (PrEP) for HIV. Men who have sex with men account for more than two-thirds of new HIV infections in the United States. Previous randomized clinical trials have demonstrated the efficacy of PrEP in preventing HIV infection. However, little is known about adherence to the PrEP regimen, sexual practices and overall effectiveness when PrEP is implemented at STI and community-based clinics serving MSM. Albert Y. Liu, M.D., M.P.H., of the San Francisco Department of Public Health, and coauthors report on the results of a demonstration project that assessed PrEP adherence, sexual practices and incidence of STIs and HIV infection among MSM and transgender women in San Francisco, Miami and Washington, D.C. The project enrolled participants from two municipal STI clinics in San Francisco and Miami and at a community health center in Washington...

At the least 10 % of youngsters in international locations of southern Africa reside in HIV-affected households, with the determine rising to 36 % in some areas. These youngsters stay some of the susceptible, but understudied populations within the area. Credit score: Susan Quick/Brown College Sub-Saharan Africa has lengthy been recognized to have the very best charges of HIV/AIDS on this planet. However a brand new research printed on this month's difficulty of  PLOS One  reveals that regardless of the concentrate on the area, few estimates exist of one in all its most susceptible populations: youngsters residing in households with HIV-infected adults. Whereas researching a separate venture in Lesotho, Susan Quick, professor of sociology, college affiliate of the Inhabitants Research and Coaching Heart at Brown College, and the lead writer on the pape...

The duvet picture of the present challenge of the journal Lab on a Chip reveals an artist's conception of a reusable acoustic tweezers machine (backside) with a disposable microfluidic laboratory for cell manipulation and illness analysis. Credit score: Huang Lab/Penn State The event of a reusable microfluidic machine for sorting and manipulating cells and different micro/nano meter scale objects will make biomedical analysis of ailments cheaper and extra handy in areas the place medical amenities are sparse or price is prohibitive. Researchers at Penn State have just lately filed a patent to develop such a tool. Primarily based on mild acoustic vibrations, the machine, known as acoustic tweezers, is the work of Penn State professor of engineering science and mechanics, Tony Huang and his college students. Their work is the quilt article for the present chal...

HIV sufferers could profit from combining antiviral and immunotherapy. Credit score: Cristina Peligero et al, CC-BY Persistent HIV an infection ends in exhaustion of the immune system, a phenomenon characterised by dysfunctional HIV-specific killer T cells. The exhausted T cells show inhibitory proteins on their floor, and scientists hope to have the ability to restore immune perform by interfering with the damaging alerts transmitted by such proteins. A examine revealed on December third in  PLOS Pathogens means that one such technique blocking the PD-1/PD-L1 pathway works, however solely when the general HIV load is low and regulatory T cells cooperate. Interplay between the PD-1 protein discovered on killer T cells and its binding associate PD-1L is one hallmark of immune exhaustion, and interfering with this interplay a possible technique to beat it. Primari...

An lively cytomegalovirus an infection within the lung of an individual with AIDS. Credit score: CDC/Edwin P. Ewing Jr. Not each virus desires to go viral -- at the least, not instantly. Some need to slip in quietly. Cover. Await the proper alternative to assault. So as to take action, the virus has to discover a technique to enter the cells of the human physique with out tripping the alarm, and keep there with out discover. It is how HIV works, and in addition how viruses within the herpesvirus household, like human cytomegalovirus (HCMV), do their enterprise. In a brand new examine printed in  Science Advances , a bunch of College of Wisconsin-Madison researchers present that particular person cells within the human physique have an armament designed to forestall HCMV from reaching and sustaining this latency, to shine a highlight on the virus so the immune s...

HIV disproportionately affects men who have sex with men (MSM). Young MSM (YMSM, ages 13 to 29) are particularly vulnerable to HIV infection and more than one-quarter of new infections in the U.S. occur in YMSM. The success of treatment as prevention in reducing the number of new HIV infections among YMSM relies on HIV testing, antiretroviral treatment, adherence and viral suppression among YMSM with HIV. Behavioral approaches to improve engagement in care and medication adherence may need to occur in concert with interventions to reduce risky sexual behaviors, including condomless anal intercourse (CAI). Patrick A. Wilson, Ph.D., of the Columbia University Mailman School of Public Health, New York, and coauthors examined differences in demographic and psychosocial factors between virologically suppressed YMSM and those with detectable HIV. The authors also sought to identify psychosocial factors associated with CAI and serodiscordant (between partners of differing HIV status) CA...
