Fibrotic diseases cause high rates of morbidity and mortality, and their incidence increases with age. Despite intense research and development efforts, effective and well-tolerated antifibrotic treatments are scarce. Transforming growth factor-β signaling, which is widely considered the most important profibrotic factor, causes a pro-oxidant shift in redox homeostasis and a concomitant decrease in nitric oxide (NO) signaling. The NO/cyclic guanosine monophosphate (cGMP) signaling cascade plays a pivotal role in the regulation of cell and organ function in whole-body hemostasis...

Over 11 million voluntary medical male circumcisions (VMMC) have been performed of the projected 20.3 million needed to reach 80% adult male circumcision prevalence in priority sub-Saharan African countries. Striking numbers of adolescent males, outside the 15-49-year-old age target, have been accessing VMMC services. What are the implications of overall progress in scale-up to date? Can mathematical modeling provide further insights on how to efficiently reach the male circumcision coverage levels needed to create and sustain further reductions in HIV incidence to make AIDS no longer a public health threat by 2030? Considering ease of implementation and cultural acceptability, decision makers may also value the estimates that mathematical models can generate of immediacy of impact, cost-effectiveness, and magnitude of impact resulting from different policy choices...

OBJECTIVES: A considerable volume of experimental evidence demonstrates that exposure to aging stereotypes can strongly influence cognitive performance among older individuals. However, whether such effects extend to stereotypes regarding older adults' generative (i.e. contributory) worth is not yet known. The present investigation sought to evaluate the effect of exposure to positive versus negative generative value primes on an important aspect of later life functioning, memory. METHOD: Participants of age 55 and older (n = 51) were randomly assigned to read a mock news article portraying older individuals as either an asset (positive prime) or a burden (negative prime) to society...

Evidence from literature illustrates that from a pathophysiological perspective, sulfonylureas (SU) may impact the heart three ways: directly by intrinsic properties from a pharmacological receptor perspective, indirectly by adverse effects related to hypoglycemia, and obesity. From a pharmacologlogical receptor perspective, SU can bind to ATP-sensitive potassium channels in cardiomyocytes. Channel binding by SU in cardiac tissue may prevent ischemia myocardial protective mechanisms. From a pathophysiological perspective, obesity is associated with cardiac issues such as pulmonary hypertension, left ventricular hypertrophy, arrhythmia, and atrial fibrillation...

There is growing concern that although the more severe forms of HIV-associated neurologic deficits are reduced following highly active anti-retroviral therapy (HAART), mild to moderate cognitive disorders may persist for years after HAART initiation and this may occur despite complete plasma viral suppression. According to the UNAIDS 2014 report, there were 3.2 million children living with HIV around the world at the end of 2013 and 91 % of these resided in sub-Saharan Africa. In the same year, only 24 % of children who needed antiretroviral treatment (ART) received it and 190,000 children died of AIDS-related illnesses...

INTRODUCTION: Patients with type 2 diabetes mellitus (T2DM) have usually been found cognitive impairment associated with brain white matter (WM) abnormalities. However, findings have varied across studies, and any potential relationship with Alzheimer's disease (AD) remains unclear. The aim of this study was to assess the whole-brain WM integrity of T2DM patients and to compare our findings with those of published AD cases. METHODS: In this study, we used diffusion tensor imaging (DTI) combined with tract-based spatial statistics (TBSS) to investigate whole-brain WM abnormalities in 48 T2DM patients and 48 healthy controls...

Considering the increased speed at which the world population is aging, sarcopenia could become an epidemic in this century. This condition currently has no means of prevention or treatment. Melatonin is a highly effective and ubiquitously acting antioxidant and free radical scavenger that is normally produced in all organisms. This molecule has been implicated in a huge number of biological processes, from anticonvulsant properties in children to protective effects on the lung in chronic obstructive pulmonary disease...

In vitro cell culture system for adult rod and cone photoreceptor (PR) is an effective and economical model for screening drug candidates against all kinds of age related retinal blindness. Interestingly, adult PR cells have a limited survival in the culture system, thus preventing full exploitation of this in vitro approach for drug screening applications. The limited survival of the adult PR cells in culture is due to their inherently high oxidative stress and photic injury. Mixed valence-state ceria nanoparticles have the ability to scavenge free radicals and reduce oxidative stress...

Despite considerable research on secondary traumatization, the ramifications of veterans' and their wives' posttraumatic stress symptoms (PTSS) for the family system remain largely uninvestigated. Beginning to fill this gap, the current study aims to investigate the reciprocal relations between both spouses' PTSS and marital adjustment, and the implications these bear for their parental functioning. Two hundred and twenty-five Israeli veterans (mean age = 58.62, SD = 7.6) from the 1973 Yom Kippur War and their wives (mean age = 58...

Domestication is thought to increase stress tolerance. The connection between stressor exposure, glucocorticoids and behavioural responses has been studied in adults, where domestication effects are evident. Early stress exposure may induce detrimental effects both in short-and long term. Previous research has reported a lack of glucocorticoid response in newly hatched chickens (Gallus gallus), whereas others have found opposite results. Hence it remains unclear whether the HPA-axis is functional from hatch, and if domestication has affected the early post-hatch ontogeny of the stress response...

BACKGROUND: Major depressive disorder (MDD) creates debilitating effects on a wide range of cognitive functions, including reinforcement learning (RL). In this study, we sought to assess whether reward processing as such, or alternatively the complex interplay between motivation and reward might potentially account for the abnormal reward-based learning in MDD. METHODS: A total of 35 treatment resistant MDD patients and 44 age matched healthy controls (HCs) performed a standard probabilistic learning task...
