One group of N. annamensis was studied, and focal animal sampling was used to observe their feeding behavior. The study was conducted for 4 months (January-April 2015) in the dry season and 69 foods were collected for nutritional analyses. N. annamensis fed on 37 plant species, but only seven species made up more than 80% of feeding time. N. annamensis spent the majority of their time feeding on fruit (60...

In this work, a novel aptamer-based electrochemical biosensor was developed for the determination of Ochratoxin A (OTA) by using carbon aerogels (CAs) and methylene blue (MB) as signal amplification strategy. CAs was used as carrier to load the abundant of complementary DNA (cDNA), which could enhance the hybridization between CAs-cDNA and aptamer immobilized on the electrode surface, thus provide more double-stranded DNA for MB intercalation. The current of MB on the CAs-cDNA/apt/AuE sensor was twice that on the cDNA/apt/AuE sensor, which indicated that the CAs with high surface area enabled a higher loading of the cDNA and absorbed more MB, thus realized the signal amplification strategy...

BACKGROUND: Numerous epidemiological studies among health care staff have documented associations of adverse psychosocial working conditions with poorer health-related outcomes, a reduced quality of patient care and intentions to leave the profession. The evidence for physician assistants in Germany remains limited though. METHODS: We surveyed a total of 994 physician assistants between September 2016 and April 2017. Psychosocial working conditions were measured by the established effort-reward imbalance (ERI) questionnaire and by a questionnaire specifically developed to capture psychosocial working conditions among physicians...

BACKGROUND: Solid renal masses are increasingly treated with nephron-sparing surgery. As in other uro-oncological surgical techniques, minimally invasive and robotic-assisted techniques are becoming increasingly popular. OBJECTIVES: The perioperative results from minimally invasive nephron-sparing surgery versus open surgery were retrospectively compared. MATERIALS AND METHODS: In our single center retrospective study, all patients who underwent nephron-sparing tumor excision between 2006 and 2016 were divided into two groups (group O = open approach and group M = minimally invasive approach)...

Nature can efficiently recognize specific ions by exerting second-sphere interactions onto well-folded protein scaffolds. However, a considerable challenge remains to artificially manipulate such affinity, while being cost-effective in managing immense amounts of water samples. Here, we propose an effective approach to regulate uranyl capture performance by creating bio-inspired nano-traps, illustrated by constructing chelating moieties into porous frameworks, where the binding motif's coordinative interaction towards uranyl is enhanced by introducing an assistant group, reminiscent of biological systems...

PURPOSE: To evaluate mammographers' acceptance of the breast cancer risk assessment software tool MammoRisk (Statlife) in the clinical setting. METHODS: During a 6-month period, 1200 women undergoing routine mammography examinations at a regional, outpatient, comprehensive breast imaging center were assessed for breast cancer risk by mammographers who used the MammoRisk software. At the end of the 6-month period, the mammographers (N = 11) completed an 8-question survey on their willingness to the use of the software in the clinical setting...

Cholesterol is an important regulator of cell signaling, both through direct impacts on cell membranes and through oxy-metabolites that activate specific receptors (steroids, hydroxy-cholesterols, bile acids). Cholesterol moves slowly through and between cell membranes with the assistance of specific binding proteins and transfer processes. The prototype cholesterol regulator is the Steroidogenesis Acute Regulatory (STAR), which moves cholesterol into mitochondria, where steroid synthesis is initiated by cytochrome P450 11A1 in multiple endocrine cell types...

PURPOSE: Results of an evaluation of a one-dose package medication support system (ODP-MSS) for medication support and telecare home monitoring of elderly persons are reported. METHODS: ODP-MSS units were provided to 10 elderly patients living at home, with adherence assistance provided by family members or other medication supporters in response to telephone alerts. In addition, ODP-MSS units were installed in 2 group homes.

Matrix Assisted Laser Desorption/Ionization and Time of Flight mass spectrometry (MALDI-TOF MS) is a powerful tool for the identification of bacteria through the detection and analysis of their proteins or fragments derived from ribosomes. Slight sequence variations in conserved ribosomal proteins distinguish microorganisms at the subspecies and strain levels. Characterization of Leptospira spp. by 16S RNA sequencing is costly and time-consuming, and recent studies have shown that closely related species (e...

BACKGROUND: Total knee arthroplasty volume is increasing significantly in the United States. Reducing hospital length of stay may represent the best method for accommodating expanding volume and reducing costs. We hypothesized that tailoring a clinical pathway to facilitate early ambulation would decrease costs and resource utilization. METHODS: We conducted a sequential before-and-after study of total knee arthroplasty patients after a phased implementation of a clinical pathway that includes multimodal oral analgesic protocols, adductor canal nerve block, and standardized day of surgery ambulation protocols...

BACKGROUND: Total knee arthroplasty (TKA) systems provide a set of incrementally sized tibial and femoral components intended to accommodate most knee parameters. However, the most commonly used systems in the United States were developed using data from Caucasian patients which might not lead to the best fit in non-Caucasians. Therefore, we wanted to evaluate whether these TKA systems proportionally match femoral and tibial measurements in Hispanics. METHODS: All lower extremity magnetic resonance imaging performed at our institution between January 2007 and October 2015 were screened...

Patients often feel lost when navigating the health care system, and poor care coordination leads to negative patient outcomes, consumes resources and makes diseases more difficult to treat. Patients and citizens have become eager to take health care decision making into their own hands. To this end, solutions have been proposed which assist patients by providing them with more information and enabling them to take a more active role in their care. These include enlisting a patient navigator, consumer engagement, process mapping, decision aids, and clinical pathways...

Gellan gels were produced using different approaches forming structures with varied potential applications. Gels were characterized from appearance, mechanical properties, water holding capacity (WHC) and microstructure. In addition, in vitro digestibility of these gels was evaluated to understand the effect of gastrointestinal environment on their structure stability. All gels presented high WHC (>80% w/w) but gels were stronger with salt or acid addition, which was associated to the reduction of double helices repulsion of the negatively charged carboxyl groups of gellan...
