Inferring ecosystem functioning and ecosystem services through inspections of the species inventory is a major aspect of ecological field studies. Ecosystem functions are often stable despite considerable species turnover. Using metatranscriptome analyses, we analyse a thus-far unparalleled freshwater dataset which comprises 21 mainland European freshwater lakes from the Sierra Nevada (Spain) to the Carpathian Mountains (Romania) and from northern Germany to the Apennines (Italy) and covers an altitudinal range from 38 m above sea level (a...

OBJECTIVE: The majority of pediatric asthma is atopic, but whether pediatric obese asthma is atopic is indeterminate in the literature. In Nevada, children become sensitized to aeroallergens, a risk factor for asthma, at young ages. Additionally, Nevada children have high rates of obesity. Our objective is to determine whether elevated body mass index (BMI) is associated with asthma severity, allergen sensitization, and polysensitization. METHODS: Medical records from a pediatric allergy clinic provided BMI percentile, physician-diagnosed asthma severity, skin prick test data, and sociodemographics such as age, race, sex, and insurance status from asthmatic patients...

OBJECTIVES: Patients treated with oral chemotherapy appear to have less contact with the treating providers. As a result, safety, adherence, medication therapy monitoring, and timely follow-up may be compromised. The trend of treating cancer with oral chemotherapy agents is on the rise. However, standard clinical guidance is still lacking for prescribing, monitoring, patient education, and follow-up of patients on oral chemotherapy across the healthcare settings. The purpose of this project is to establish an oral chemotherapy monitoring clinic, to create drug and lab specific provider order sets for prescribing and lab monitoring, and ultimately to ensure safe and effective treatment of the veterans we serve...

This study explored how unique environmental conditions in Alaska influenced occupational health and safety for Filipino fish processing workers, many of whom migrated from warm locations (e.g., the Philippines, California, and Nevada). In-depth interviews were conducted with 26 Filipino workers in one commercial fish processing company in Dutch Harbor. Results indicated that cold weather interferes with workers' job performance, increasing their risk for injury and illness, whereas the community's isolation and rural nature causes loneliness and boredom, resulting in more high-risk behaviors...

INTRODUCTION: Patient-specific implants and instruments (PSI) have been used in both knee and shoulder replacements due to the perceived benefits of improved surgical accuracy and efficiency. The proposed benefits of using a PSI in total hip arthroplasty (THA) are numerous and include reduction of operative time and improved mechanical and anatomical alignment leading to increased implant longevity, increased stability, and clinical outcomes. We describe a novel patient-specific instrumentation and a surgical method that may improve directed resection of acetabular bone and accurate cup placement during THA...

There has been an ongoing debate regarding the forced use of antipsychotic medications and both the psychiatric and legal professions have reacted strongly to the growing debate. Within the penological context, cases such as Washington v. Harper, Riggins v. Nevada, and Sell v. United States established the framework for determining when antipsychotic medication may be forcibly administered. Medication decisions under the Sell and Riggins cases are to be approved at judicial hearings; whereas, administrative hearings are sufficient for Harper cases...

Similar to asbestos fibers, nonregulated mineral fibers can cause malignant mesothelioma (MM). Recently, increased proportions of women and young individuals with MM were identified in southern Nevada, suggesting that environmental exposure to carcinogenic fibers was causing the development of MM. Palygorskite, a fibrous silicate mineral with a history of possible carcinogenicity, is abundant in southern Nevada. In this study, our aim was to determine whether palygorskite was contributing to the development of MM in southern Nevada...

We investigated the prevalence of Bartonella washoensis in California ground squirrels (Otospermophilus beecheyi) and their fleas from parks and campgrounds located in seven counties of California. Ninety-seven of 140 (69.3%) ground squirrels were culture positive and the infection prevalence by location ranged from 25% to 100%. In fleas, 60 of 194 (30.9%) Oropsylla montana were found to harbor Bartonella spp. when screened using citrate synthase (gltA) specific primers, whereas Bartonella DNA was not found in two other flea species, Hoplopsyllus anomalus (n = 86) and Echidnophaga gallinacea (n = 6)...

To better understand the potential avian diseases in Greater Sage-grouse ( Centrocercus urophasianus ) in the Great Basin in Nevada, we collected 31 blood samples March-April 2014 and tested for antibodies to eight viruses and two bacteria. Specifically, sera were tested for antibodies to avian leukosis virus type A, B, and J (ALV-A, ALV-B, and ALV-J, respectively), infectious bursal disease virus, infectious bronchitis virus, reticuloendothelial virus, avian influenza virus (AIV), West Nile virus, Pasteurella multocida (PM), and Salmonella enterica serovar Pullorum...

The incidence of coccidioidomycosis (CM) infection has increased over the last 20 years. We investigated recent trends of CM-associated hospitalization in the United States. patients with CM-associated hospitalization were identified from the Nationwide Inpatient Sample, 2005-2012. The outcomes of interest were the trend of annual hospitalization, in-hospital mortality, and independent risk factors for mortality. A total of 30,870 hospitalizations with CM (29,584 of adults; 1,286 of children) were identified...

Amphibians are one of the most threatened animal groups, with 32% of species at risk for extinction. Given this imperiled status, is the disappearance of a large fraction of the Earth's amphibians inevitable, or are some declining species more resilient than is generally assumed? We address this question in a species that is emblematic of many declining amphibians, the endangered Sierra Nevada yellow-legged frog (Rana sierrae). Based on >7,000 frog surveys conducted across Yosemite National Park over a 20-y period, we show that, after decades of decline and despite ongoing exposure to multiple stressors, including introduced fish, the recently emerged disease chytridiomycosis, and pesticides, R...

: Safe and effective nuclear waste disposal, as well as accidental radionuclide releases, necessitates our understanding of the fate of radionuclides in the environment, including their interaction with microorganisms. We examined the sorption of Pu(IV) and Pu(V) to Pseudomonas sp. strain EPS-1W, an aerobic bacterium isolated from plutonium (Pu) contaminated groundwater collected in the United States at the Nevada National Security Site (NNSS), Nevada. We compared Pu sorption to cells with and without bound extracellular polymeric substances (EPS)...

Soils are an important source of NO, particularly in dry lands because of tradeoffs that develop between biotic and abiotic NO-producing processes when soils dry out. Understanding how drier climates may offset the balance of these tradeoffs as soils transition toward more arid states is, therefore, critical to estimating global NO budgets, especially because drylands are expected to increase in size. We measured NO emission pulses after wetting soils from similar lithologies along an altitudinal gradient in the Sierra Nevada, CA, where mean annual precipitation varied from 670 to 1,500 mm...

California has experienced a dry 21(st) century capped by severe drought from 2012 through 2015 prompting questions about hydroclimatic sensitivity to anthropogenic climate change and implications for the future. We address these questions using a Holocene lake sediment record of hydrologic change from the Sierra Nevada Mountains coupled with marine sediment records from the Pacific. These data provide evidence of a persistent relationship between past climate warming, Pacific sea surface temperature (SST) shifts and centennial to millennial episodes of California aridity...

Relevant mineral fibres of social and economic importance (chrysotile UICC, crocidolite UICC and a fibrous erionite from Jersey, Nevada, USA) were put in contact with cultured diploid human non-tumorigenic bronchial epithelial (Beas2B) and pleural transformed mesothelial (MeT5A) cells to test their cytotoxicity. Slides of each sample at different contact times up to 96 h were studied in situ using synchrotron XRF, μ-XRD and μ-XAS (I18 beamline, Diamond Light Source, UK) and TEM investigations. XRF maps of samples treated for 96 h evidenced that iron is still present within the chrysotile and crocidolite fibres and retained at the surface of the erionite fibres, indicating its null to minor mobilization in contact with cell media; this picture was confirmed by the results of XANES pre-edge analyses...

The origins of the Behavior Analysis program at the University of Nevada, Reno by way of a self-capitalized model through its transition to a more typical graduate program is described. Details of the original proposal to establish the program and the funding model are described. Some of the unusual features of the program executed in this way are discussed, along with problems engendered by the model. Also included is the diversification of faculty interests over time. The status of the program, now, after 25 years of operation, is presented...

Higher global temperatures and increased levels of disturbance are contributing to greater tree mortality in many forest ecosystems. These same drivers can also limit forest regeneration, leading to vegetation type conversion. For the Sierra Nevada of California, little is known about how type conversion may affect streamflow, a critical source of water supply for urban, agriculture and environmental purposes. In this paper, we examined the effects of tree-to-shrub type conversion, in combination with climate change, on streamflow in two lower montane forest watersheds in the Sierra Nevada...

Schools are important settings for not only providing and promoting children's physical activity (PA) but also for reducing PA disparities. We investigated associations between school-level demographic characteristics (racial/ethnic and socioeconomic composition, urban-rural status, and student-to-teacher ratio) and 16 PA-promoting practices in 347 Nevada public elementary, middle, and high schools in 2014. We found that low-cost and easy-to-implement practices are most prevalent. There is relative demographic equity in ten of 16 PA practices and significant differences in six PA practices in Nevada schools...

BACKGROUND: Despite today's heightened concern over opioid overdose, the lack of population-based data examining clinical and contextual factors associated with opioid use represents a knowledge gap with relevance to prevention and treatment interventions. We sought to quantify rates of emergency department (ED) visits and inpatient hospitalizations for harmful opioid effects and their sociodemographic differentials as well as clinical correlates in Southern Nevada, using ED visit and hospital inpatient discharge records from 2011 to 2013...
