#1
Juan C Mayo, Rosa M Sainz, Pedro González Menéndez, Vanesa Cepas, Dun-Xian Tan, Russel J Reiter
Epigenetic modifications, including methylation or acetylation as well as posttranscriptional modifications are mechanisms used by eukaryotic cells to increase the genome diversity in terms of differential gene expression and protein diversity. Among these modifying enzymes, sirtuins, a class III histone deacetylase (HDAC) enzymes are of particular importance. Sirtuins regulate the cell cycle, DNA repair, cell survival and apoptosis, thus having important roles in normal and cancer cells. Sirtuins can also regulate metabolic pathways by changing preference for glycolysis under aerobic conditions as well as glutaminolysis...

Dating violence is a serious and prevalent problem on college campuses. Although there is a robust literature documenting that alcohol use is consistently associated with increased risk for perpetrating dating violence, little research has examined the role of cannabis in dating violence perpetration. With increasing legalisation of cannabis throughout the world, it is imperative to understand what role, if any, cannabis may play in the important public health problem of dating violence. In this commentary, we discuss the current state of the research on cannabis and dating violence and suggest avenues for additional research in this area...

REVIEW
Asbjørn Jokstad
The objective of this systematic review is to identify current computer-assisted technologies used for managing patients with a need to re-establish craniofacial appearance, subjective discomfort and stomatognathic function, and the extent of their clinical documentation. Electronic search strategies were used for locating clinical studies in MEDLINE through PubMed and in the Cochrane library, and in the grey literature through searches on Google Scholar. The searches for commercial digital products for use in oral rehabilitation resulted in identifying 225 products per November 2016, used for patient diagnostics, communication and therapy purposes, and for other computer-assisted applications in context with oral rehabilitation...

The Holy Qur'ān and medieval Islamic writings have many references to "hope" (rajā) and "fear" (khawf) as both single and paired concepts. However, a comprehensive analytical study on these two notions from an Islamic point of view still seems lacking. Both paper and electronic documents related to Islamic and Qur'ānic literature are being used in this study. Also Web resources are searched for keywords of fear, hope and Islam in three languages of Arabic, English and Persian, including Tanzil.net, Almaany...

Mining activities are responsible for high concentrations of metals in river networks in many parts of the world. Mining activities and the resulting high loads of heavy metals interact with intensive acid rain, and often have great consequences for biodiversity. However, considering the frequently episodic nature of these heavy acid rains, there is little detailed evidence of direct impacts. In 2011 we observed a massive mortality of noble crayfish and stone crayfish in Padrťsko Special Area of Conservation (SAC) in the Brdy Mountain region of the Czech Republic...

Indiana recently passed legislation allowing local governments to establish syringe exchanges. While the effectiveness of syringe exchange programming is established, there is a dearth of studies about associated policy adoption and implementation. This study documents the experiences of 24 Indiana counties engaged in the process of establishing syringe exchange programming under new state law. A mixed method, qualitative, exploratory case study was conducted from May 2015 to April 2016. We observed rapid and widespread policy adoption interest, and yet counties reported significant policy ambiguity, epidemiologic and resource capacity issues...

PURPOSE: The Statistical Parametric Mapping (SPM) software is frequently used for the quantitative analysis of patients' brain images obtained from 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography ([(18)F]FDG PET). However, its adaptation to small animals is difficult, particularly for the initial step of spatial normalization which requires a specific brain anatomical template. This study was aimed at determining whether SPM analysis can be applied to rat, and more specifically to the lithium-pilocarpine model of epilepsy, by using an adaptive template...

OBJECTIVE: Transient urinary retention has been recognized as a complication of bilateral ureteroneocystostomy (UNC), when performed extravesically. The objective of this study was to review a collective surgeons' experiences of unilateral extra- and unilateral and/or bilateral intra-vesical ureteral reimplanation, where urinary retention greater than 6 weeks, or what we have termed, "prolonged urinary retention" (PUR), occurred. MATERIALS AND METHODS: We retrospectively reviewed charts to identify PUR after any open or robotic reimplant, other than bilateral extravesical, between 1998 and 2015 as reported by five surgeons...

This study provides evidence for those working in the maternal health metrics and health system performance fields, as well as those interested in achieving universal and effective health care coverage. Based on the perspective of continuity of health care and applying quasi-experimental methods to analyse the cross-sectional 2009 National Demographic Dynamics Survey (n = 14 414 women), we estimated the middle-term effects of Mexico's new public health insurance scheme, Seguro Popular de Salud (SPS) (vs women without health insurance) on seven indicators related to maternal health care (according to official guidelines): (a) access to skilled antenatal care (ANC); (b) timely ANC; (c) frequent ANC; (d) adequate content of ANC; (e) institutional delivery; (f) postnatal consultation and (g) access to standardized comprehensive antenatal and postnatal care (or the intersection of the seven process indicators)...

OBJECTIVE: It is still not clear whether Gamma knife Radiosurgery (GKRS) for non-functional pituitary adenomas (NFPA) should be used as a standard adjuvant postoperative therapy or applied when there is documented progression of the remnant on the follow-up (FU) MRI. METHODS: We performed a retrospective study of patients with non-functional pituitary adenomas who underwent primary surgery and GKRS between 2002 and 2015. Patients were divided into two groups based on the GKRS indication: adjuvant treatment (GKRS ≤6 months postoperatively) or delayed treatment (GKRS if documented progression occurred on the FU MRI)...

Karyotyping is a basic method to investigate chromosomal evolution and genomic rearrangements. Sixteen genera within the basal teleost order Osteoglossiformes are currently described cytogenetically. Our study adds information to this chromosomal dataset by determining the karyotype of Campylomormyrus compressirostris, a genus of African weakly electric fish that has not been previously examined. Our results indicate a diploid chromosome number of 2n=48 (4sm + 26m + 18a) with a fundamental number of FN=72. This chromosome number is identical to the number documented for the sister taxon of the genus Campylomormyrus, i...

Methionine restriction (MR) extends lifespan across different species. The main responses of rodent models to MR are well-documented in adipose tissue (AT) and liver, which have reduced mass and improved insulin sensitivity, respectively. Recently, molecular mechanisms that improve healthspan have been identified in both organs during MR. In fat, MR induced a futile lipid cycle concomitant with beige AT accumulation, producing elevated energy expenditure. In liver, MR upregulated fibroblast growth factor 21 and improved glucose metabolism in aged mice and in response to a high-fat diet...

In Parkinson's disease (PD), several efforts have been spent in order to find biochemical parameters able to identify the progression of the pathological processes at the basis of the disease. It is already known that advanced PD patients manifesting dyskinesia are featured by the high homovanillic acid (HVA)/dopamine (DA) ratio, suggesting the increased turnover of DA in these patients. Less clear is whether similar changes affect mild and moderate stages of the disease (between 1 and 2.5 of Hoehn & Yahr -H&Y- stage)...
