Bovine leukemia virus (BLV) is a member of the genus Deltaretrovirus of the family Retroviridae and cause a chronic lymphosarcoma, which is extensive in cattle. In yaks (Bos grunniens), the distribution, strains and genetic characteristics of BLV have rarely been studied. The aim of our study was to investigate BLV infections in domestic yaks and determine the genetic variability of BLV circulating in a region of the Qinghai Tibet Plateau, China. Blood samples were collected from 798 yaks, which were from different farms from Gansu, Qinghai and Sichuan provinces surrounding the Qinghai-Tibet Plateau...

BACKGROUND: Improved imaging methods are critical to assess neurodegeneration and remyelination in multiple sclerosis. Chronic hypointensities observed on T1-weighted brain MRI, "persistent black holes," reflect severe focal tissue damage. Present measures consist of determining persistent black holes numbers and volumes, but do not quantitate severity of individual lesions. OBJECTIVE: Develop a method to differentiate black and gray holes and estimate the severity of individual multiple sclerosis lesions using standard magnetic resonance imaging...

Dissolved black carbon (DBC) is ubiquitous in aquatic systems, being an important subgroup of the dissolved organic matter (DOM) pool. Nevertheless, its aquatic photoactivity remains largely unknown. In this study, a range of spectroscopic indices of DBC and humic substance (HS) samples were determined using UV-Vis spectroscopy, fluorescence spectroscopy, and proton nuclear magnetic resonance. DBC can be readily differentiated from HS using spectroscopic indices. It has lower average molecular weight, but higher aromaticity and lignin content...

BACKGROUND: Despite the availability of a safe and efficacious vaccine against HPV, uptake of the vaccine in the United States is low. Missed clinical opportunities to recommend and to administer HPV vaccine are considered one of the most important reasons for its low uptake in adolescents, however, little is known about the frequency or characteristics of missed opportunities in the young adult (18-26 years of age) population. OBJECTIVES: To assess both the rates of and the factors associated with missed opportunities for HPV immunization among young adult women who attended an urban obstetrics and gynecology clinic...

Cisplatin (CP) is an effective anti-cancer drug which causes remarkable toxicity to the kidney, particularly to proximal tubules, by generating reactive oxygen species. Nigella sativa (NS), commonly known as "black cumin" reduces the progression of various kidney disorders. Thymoquinone (TQ), the major bioactive constituent of NS seeds, has been credited for various pharmacological effects of NS. Since, a typical clinical CP dosing regimen involves CP administration in multiple cycles over a long time duration, hence the present study aimed to evaluate the renoprotective efficacy of NS oil and TQ against multiple dose CP treatment induced deleterious biochemical and histological alterations in rat kidney...

BACKGROUND: Statin therapy is highly efficacious in the prevention of fatal and nonfatal atherosclerotic events in persons at increased cardiovascular risk. However, its long-term effectiveness in practice depends on a high level of medication adherence by patients. METHODS: We identified nondiabetic adults with cardiovascular risk factors between 2008 and 2010 within a large integrated health care delivery system in Northern California. Through 2013, we examined the use and adherence of newly initiated statin therapy based on data from dispensed prescriptions from outpatient pharmacy databases...

Artemether (ATM) cardiotoxicity, its short half-life and low oral bioavailability are the major limiting factors for its use to treat malaria. The purposes of this work were to study free-ATM and ATM-loaded poly-ε-caprolactone nanocapules (ATM-NC) cardiotoxicity and oral efficacy on Plasmodium berghei-infected mice. ATM-NC was obtained by interfacial polymer deposition and ATM was associated with polymeric NC oily core. For cardiotoxicity evaluation, male black C57BL6 uninfected or P. berghei-infected mice received, by oral route twice daily/4 days, vehicle (sorbitol/carboxymethylcellulose), blank-NC, free-ATM or ATM-NC at doses 40, 80 or 120 mg kg-1...

Scarce land resources in dense cities means that small urban parks are important as a leisure and amenity resource for the urban population. However, streets with heavily traffic often surround these fragmented parks and increase the potential user exposure to air pollutants from vehicles. The dispersion profiles of PM2.5 and black carbon from roadside into urban parks at pedestrian level, in Hong Kong, were measured using mobile high time resolution instruments. In the downwind direction, pollutant concentrations decreased rapidly from roadside and by some tens of metres reached relatively constant values...

BACKGROUND: Although inequities in trauma care are reported widely, some groups have theorized that universal health insurance would decrease disparities in care for disadvantaged minorities after a traumatic injury. We sought to examine the presence of racial disparities in outcomes and healthcare utilization at 30- and 90-days after discharge in this universally insured, racially diverse, American population treated for traumatic injuries. METHODS: This work studied adult beneficiaries of TRICARE treated at both military and civilian trauma centers 2006-2014...
