The US National Library of Medicine and National Institutes of Health manage PubMed.gov which comprises of more than 21 million records, papers, reports for biomedical literature, including MEDLINE, life science and medical journals, articles, reviews, reports and books. BioPortfolio aims to publish relevant information on published papers, clinical trials and news associated with users selected topics.
For example view all recent relevant publications on Epigenetics and associated publications and clincial trials.
Few transgender youth eligible for gender-affirming treatments actually receive them. Multidisciplinary gender clinics improve access and care coordination but are rare. Although experts support use of pubertal blockers and cross-sex hormones for youth who meet criteria, these are uncommonly offered. This study's aim was to understand barriers that transgender youth and their caregivers face in accessing gender-affirming health care.
The sedimentation of a single particle in materials that exhibit simultaneously elastic, viscous and plastic behavior is examined in an effort to explain phenomena that contradict the nature of purely yield-stress materials. Such phenomena include the loss of the fore-and-aft symmetry with respect to an isolated settling particle under creeping flow conditions and the appearance of the "negative wake" behind it. Despite the fact that similar observations have been reported in studies involving viscoelastic ...
There is evidence that yoga could improve the symptoms of asthma and boost quality of life, but the effects on lung function and medication use are uncertain, new research has found.
The distribution of Yucca brevifolia, a keystone species of the Mojave Desert, may contract with climate change, yet reproduction and dispersal are poorly understood. We tracked reproduction, seed predation, and fruit dispersal for two years and discuss whether Y. brevifolia is a masting species.
Yellow fever (YF) vaccine adverse effects are not well known in dialysis patients. There is concern about risks and benefits of the vaccine in immunocompromised patients living in endemic areas, particularly given the risk of resurgence of urban yellow fever with the Aedes aegypti mosquito spread.

To determine whether state medical marijuana laws "send the wrong message," that is, have a local influence on the views of young people about the risks of using marijuana.
A two-stage master-oscillator power-amplifier (MOPA) system based on Yb:YAG single-crystal-fiber (SCF) technology and designed for high peak power is studied to significantly increase the pulse energy of a low-power picosecond laser. The first SCF amplifier has been designed for high gain. Using a gain medium optimized in terms of doping concentration and length, an optical gain of 32 dB has been demonstrated. The second amplifier stage designed for high energy using the divided pulse technique allows us to...
The results of an experimental study of the chirped pulse amplification regime are reported for the Yb:CaYAlO4 crystal with different polarization states in the gain media for the first time, to the best of our knowledge. A maximum output power of 4.2 W with 310 fs pulse duration was obtained for σ-polarization at 200 kHz repetition rate seeded by a 85 fs Yb:KYW oscillator. 215 fs pulses with an output power of 3 W and 190 fs with 2.3 W output power were demonstrated for π-polarized light in the crystal. ...
Traditionally, the regulation of apoptosis has been thought of as an autonomous process in which the dying cell dictates its own demise. However, emerging studies in genetically tractable multicellular organisms, such as Caenorhabditis elegans and Drosophila, have revealed that death is often a communal event. Here, we review the current literature on non-autonomous mechanisms governing apoptosis in multiple cellular contexts. The importance of the cellular community in dictating the funeral arrangements of...
Over 50% of young people have dated by age 15. While romantic relationship concerns are a major reason for adolescent help-seeking from counselling services, we have a limited understanding of what types of relationship issues are most strongly related to mental health issues and suicide risk. This paper used records of 4019 counselling sessions with adolescents (10-18 years) seeking help from a national youth counselling service for a romantic relationship concern to: (i) explore what types and stage (pre,...
The Hippo-YAP signaling pathway has been established as a crucial regulator of tissue growth and tumorigenesis but the mechanism for transcriptional control remains unclear. In their study, Galli et al. show that YAP/TAZ binding is restricted to a small number of gene enhancers and that YAP/TAZ regulates transcriptional elongation by recruiting the Mediator complex.
In this article, we review the advantages of language sample analysis (LSA) and explain how clinicians can make the process of LSA faster, easier, more accurate, and more insightful than LSA done "by hand" by using free, available software programs such as Computerized Language Analysis (CLAN). We demonstrate the utility of CLAN analysis in studying the expressive language of a very large cohort of 24-month-old toddlers tracked in a recent longitudinal study; toddlers in particular are the most likely group...
The CSN complex plays a key role in various cellular pathways: through a metalloprotease activity of its Csn5 deneddylating enzyme, it regulates the activity of Cullin-RING ligases (CRLs). Indeed, Csn5 has been found amplified in many tumors, but, due to its pleiotropic effects, it is difficult to dissect its function and the involvement in cancer progression. Moreover, while growing evidences point to the neddylation function as a good target for drug development; specific inhibitors have not yet been deve...
Rheumatoid arthritis (RA) is the most common type of chronic inflammatory disease which is triggered by dysfunction in the immune system which in turn affects synovial joints. Current treatment of RA with NSAIDs and DMRDs is limited by their side effect. As a result, the interest in alternative, well tolerated anti-inflammatory remedies has re-emerged. Our aim was to evaluate the antioxidant and anti-inflammatory activities underlying the anti-RA effect of Yohimbine hydrochloride (YCL) in collagen induced a...
Prior research suggests that young children selectively inform others depending on others' knowledge states. Yet, little is known whether children selectively inform others depending on their own knowledge states. To explore this issue, we manipulated 3- to 4-year-old children's knowledge about the content of a box and assessed the impact on their decisions to inform another person. Moreover, we assessed the presence of uncertainty gestures while they inform another person in light of the suggestions that c...
