We commemorate the centenary of Constantin von Economo's description of encephalitis lethargica, a mysterious disease that had a significant effect on 20th-century neuroscience. In the acute phase, encephalitis lethargica was marked by intractable somnolence, which von Economo attributed to lesions in the diencephalon, thereby paving the way for future efforts to localize the regulation of sleep in the subcortical brain. At the same time, neuropathologic findings in postencephalitic parkinsonism affirmed the role of the substantia nigra in the pathophysiology of parkinsonism...

Transgender people experience a disproportionate burden of human immunodeficiency virus (HIV) and incarceration. Discrimination, victimization, poverty, and poor mental health drive vulnerability to HIV and related infections, as well as risk of arrest, detention, and incarceration. In this paper, we systematically review published data on HIV, sexually transmitted infections, viral hepatitis, and tuberculosis among incarcerated transgender people; describe potential structural determinants of HIV risk and transmission; identify gaps in the literature; and make recommendations for research and interventions to address this neglected population...

Despite ongoing tensions in various parts of the world, the year 2017 ended on a positive note. The Treaty Prohibiting Nuclear Weapons (TPNW) was passed by the UN General Assembly on July 7, 2017, which will always be a red-letter day in history. It has raised many hopes for a future world without nuclear weapons and staved off the impending humanitarian catastrophe. Good health is a basic need of every individual. Therefore, each person yearns for a life free of violence and free of man-made catastrophes like the ones at Hiroshima and Nagasaki in 1945, which killed over two hundred thousand people and resulted in genetic mutations affecting generations thereafter...

The use of pesticides in agriculture can make their way into the earth and wash into the amphibian system causing ecological stress. This study aims to understand the changes occurring in gill tissues as a result of fenvalerate exposure using Fourier-transform infrared spectroscopy. The intensity ratio of the selected bands I1545 /I1657, I2924 /I2853 , and I1045 /I1545 measures changes in proteins, lipids, and carbohydrates. Curve-fitting analysis was performed in the selected band region to analyze the quantitative changes of proteins, lipids, and carbohydrates...

T lymphocytes, from their first encounter with their specific antigen as naïve cell until the last stages of their differentiation, in a replicative state of senescence, go through a series of phases. In several of these stages, T lymphocytes are subjected to exponential growth in successive encounters with the same antigen. This entire process occurs throughout the life of a human individual and, earlier, in patients with chronic infections/pathologies through inflammatory mediators, first acutely and later in a chronic form...

Recombinant methods have been used to engineer artificial protein triblock polymers comprised of two different self-assembling domains (SADs) bearing one elastin (E) flanked by two cartilage oligomeric matrix protein coiled-coil (C) domains to generate CEC. To understand how the two C domains improve small molecule recognition and the mechanical integrity of CEC, we have constructed CL44AECL44A, which bears an impaired CL44A domain that is unstructured as a negative control. The CEC triblock polymer demonstrates increased small molecule binding and ideal elastic behavior for hydrogel formation...

Suicide rates among military veterans exceed those found in the general population. While the exact reasons for these high rates are unknown, contributing factors may include the military's perceived rejection of patient identities, creating barriers to mental health care within the clinical sector and a mandate for prevention programs. Spiritual fitness has emerged over the last decade as an important concept in human performance optimization and is included among holistic approaches to developing and maintaining mentally fit fighting forces...

Extracurricular activity participation is linked to positive development, but it is also a setting for inequality. Using a quarter century of data from Monitoring the Future (N = 593,979; 51% female; 65% non-Hispanic white; 13% non-Hispanic black; 12% Hispanic; 4% non-Hispanic Asian/Pacific Islander; 7% other race), this article documents patterns and trends in school-based extracurricular participation by race, social class, gender, and age, and their links to academic and substance use outcomes. Findings reveal differences by race and confirm a division by social class that has worsened over time...

Topical application of honey for tissue regeneration, has recently regained attention in clinical practice with controlled studies affirming its efficacy and indicating its role in regeneration over repair. Parallely, to overcome difficulties of applying raw honey, several product development studies like nanofibrous matrices have been reported. However, one approach concentrated on achieving highest possible honey loading in the nanofiber membranes while other studies have found that only specific honey dilutions result in differential cellular responses on wound healing and re-epithelization...

Most microbial species, including model eukaryote Saccharomyces cerevisiae, possess genetic capability to utilize many alternative nutrient sources. Yet, it remains an open question whether these manifest into assimilatory phenotypes. Despite possessing all necessary pathways, S. cerevisiae grows poorly or not at all when glycerol is the sole carbon source. Here we discover, through multiple evolved lineages, genetic determinants underlying glycerol catabolism and the associated fitness trade-offs. Most evolved lineages adapted through mutations in the HOG pathway, but showed hampered osmotolerance...

Background and Objectives: Inflammatory markers that influence bone pain crisis (BPC) and other complications of sickle cell anaemia (SCA) are numerous and play various roles. This study determined the plasma levels of tumour necrosis factor (TNF) - α, interleukin - 8 (IL-8), and endothelin - 1 (ET-1) in adult SCA patients during BPC and in steady state. In addition, the plasma levels of these cytokines were correlated with the severity of BPC of the patients. Methods and Materials: Sixty adult SCA patients (30 during BPC and 30 during steady state) and 30 haemoglobin A controls were enrolled for this cross-sectional study...

BACKGROUND: Crosslinked polyethylene (XLPE) liners used for primary THA have demonstrated lower wear rates than noncrosslinked, conventional polyethylene (CPE) liners through the first decade of clinical service. However, little high-quality evidence is currently available regarding the second decade performance of these implants and it remains uncertain whether the onset of osteolysis has simply been delayed or if the wear associated with XLPE liners will remain low enough that osteolysis will not occur...
