With the development of -omics approaches, the scientific community is now submerged by a wealth of information that can be used to analyze various parameters the degree of protein sequence conservation, protein 3D structures as well as RNA and protein expression levels in various benign and tumor tissues, during organism development or upon exposure to chemicals such as endocrine disrupters. However, if such information can be used to identify genes with potentially important biological function, additional studies are needed to deeply characterize their cellular function in model organisms. Here, we discuss the case of such a gene ERH, encoding a highly conserved homodimeric protein found in unicellular eukaryotes, plants and metazoan, of yet unknown biological function, which might be linked to mRNA metabolism and that is emerging as important for cell migration and metastasis.Approximately 20% of patients have persistent unexplained pain after total knee arthroplasty (TKA). Currently available treatments are unsatisfactory. The present report describes four patients in whom transcatheter arterial embolization had a remarkable effect on pain after TKA. Abnormal neovessels were identified in all patients. For 48 h, one patient experienced remarkable postprocedural pain at the inner side of the knee that was subsided by level 1 analgesics and another patient development of a spontaneous skin ulceration resolving within 8 days. The mean Knee injury and Osteoarthritis Outcome Score pain subtotal had increased from 39 to 82 one month after treatment. Endovascular occlusion of neovascularization, decreasing chronic inflammation and the growth of unmyelinated sensory nerves may be treatment options for persistent unexplained pain following TKA.Level of Evidence IV, Case report.PURPOSE Acute lymphoblastic leukemia (ALL) is curable with standardized chemotherapy. However, the development of novel therapies is still required, especially for patients with relapsed or refractory disease. By utilizing an in vitro drug screening system, active molecular targeting agents against ALL were explored in this study. METHODS By the in vitro drug sensitivity test, 81 agents with various actions were screened for their cytotoxicity in a panel of 22 ALL cell lines and ALL clinical samples. The drug effect score (DES) was calculated from the dose-response of each drug for comparison among drugs or samples. Normal peripheral blood mononuclear cells were also applied onto the drug screening to provide the reference control values. The drug combination effect was screened based on the Bliss independent model, and validated by the improved isobologram method. selleck kinase inhibitor RESULTS On sensitivity screening in a cell line panel, barasertib-HQPA which is an active metabolite of barasertib, an aurora B kinase inhibitor, alisertib, an aurora A kinase inhibitor, and YM155, a survivin inhibitor, were effective against the broadest range of ALL cells. The DES of barasertib-HQPA was significantly higher in ALL clinical samples compared to the reference value. There were significant correlations in DES between barasertib-HQPA and vincristine or docetaxel. In the drug combination assay, barasertib-HQPA and eribulin showed additive to synergistic effects. CONCLUSION Aurora B kinase was identified to be an active therapeutic target in a broad range of ALL cells. Combination therapy of barasertib and a microtubule-targeting drug is of clinical interest.CONTEXT Cold exposure (CE) has been shown to enhance energy expenditure by activating brown adipose tissue thermogenesis and metabolism in humans. However, it remains to be elucidated if there are gender-specific differences in cold-induced thermogenesis and metabolism. OBJECTIVE To study the impact of mild CE on resting energy expenditure (REE) and metabolism in males compared to females. SETTING A cross-sectional study. PARTICIPANTS 117 healthy young Caucasians participated in this study (58 males). Mean age was 25.1 ± 3.6 years and mean BMI 22.3 ± 1.7 kg/m². INTERVENTION Participants underwent a short-term CE using water perfused mattresses to activate non-shivering thermogenesis. MAIN OUTCOME MEASURES REE was assessed before and 2 hours after CE followed by blood sampling. Selected metabolites and hormones were measured. Skin temperatures were monitored at various sites throughout the experiment. RESULTS Participants showed a significant increase in REE after CE (6.5%, p less then 0.001). This increase did not differ between genders (p=0.908). However, there were differences between males and females in changes of plasma glucose (-5.1% vs. -7.4%, p=0.024), leptin (-14.3% vs. -30.1%, p less then 0.001) and adiponectin (5.4% vs. 12.8%, p=0.018) after CE. We observed a significant decrease of the supraclavicular skin temperature in men (-0.3%, p=0.034), but not in women (0.3%, p=0.326)(p=0.019 between genders). CONCLUSIONS We did not observe a difference in the thermogenic response, measured as change of REE, to CE in women compared to men. However, we found that some metabolic and hormonal changes were more pronounced in women compared to men suggesting a gender-specific response to cold. © Endocrine Society 2020. All rights reserved.

Better understanding these phenomena will improve the effectiveness of our treatments. The objective of this work is to validate a model of three-dimensional (3D) culture of osteoblasts to study mechanobiology. MATERIALS AND METHODS The hFOB 1.19 cell line was cultured either traditionally on a flat surface or in aggregates called spheroids. They were embedded in 0.8% low-melting agarose type VII and placed in a polyethylene terephthalate transwell insert. Compressive forces of 1 and 4 g/cm2 were applied with an adjustable weight. Proliferation was evaluated by measuring diameters, monitoring glucose levels, and conducting Hoechst/propidium iodide staining. Enzyme-linked immunosorbent assays focusing on the pro-inflammatory mediators interleukin (IL)-6 and IL-8 and bone remodelling factor osteoprotegerin were performed to evaluate soluble factor synthesis. quantitative reverse transcription-polymerase chain reaction was performed to evaluate bone marker transcription. RESULTS The 3D model shows good cell viability and permits IL dosing. Additionally, three gene expression profiles are analysable. LIMITATIONS The model allows analysis of conventional markers; larger exploration is needed for better understanding osteoblast mechanobiology. However, it only allows an analysis over 3 days. CONCLUSION The results obtained by applying constant compressive forces to 3D osteoblastic cultures validate this model system for exploring biomolecule release and analysing gene transcription. In particular, it highlights a disturbance in the expression of markers of osteogenesis. © The Author(s) 2020. Published by Oxford University Press on behalf of the European Orthodontic Society.

Retention is defined as the proportion of staff continuously employed in the same facility for a defined period of time. RESEARCH DESIGN AND METHODS Data used in this investigation came from survey responses from 3,550 nursing facilities, Certification and Survey Provider Enhanced Reporting data, and the Area Resource File. Staffing characteristics, quality indicators, facility, and market information from these data sources were all measured in 2016. Nurse aide retention was measured at 1, 2, and 3 years of employment. The quality indicators examined were a count of all deficiency citations, quality of care deficiency citations, and J, K, L deficiency citations. Negative binomial regression analyses were used to study the associations between the three different retention measures and these three quality indicators. RESULTS The 1-, 2-, and 3-year nurse aide retention measures were 53.2%, 41.4%, and 36.1%, respectively. The regression analyses show low levels of retention to be generally associated with poor performance on the three deficiency citation quality indicators examined. DISCUSSION AND IMPLICATIONS The research presented starts to provide information on nurse aide retention as an important workforce challenge and its potential impact on quality. Retention may be an additional staffing characteristic of nursing facilities with substantial policy and practice relevance. © The Author(s) 2020.

There is a proprietary product (OmniGen-AF OG; Phibro Animal Health, Quincy, IL) reported to have performance enhancing benefits by altering animal response to stress and immune challenges. The objective of this 2-year research project was to study the effect of supplementing OG to beef cows and their calves on breeding and growth performance. One hundred and twelve multiparous beef cows and forty-eight primiparous cows were randomly assigned to treatment in yr 1; control (CON, no OmniGen-AF; n = 56 multiparous and 24 primiparous) or treatment (OG, OmniGen-AF fed at 8.8 g/100 kg BW; n = 56 multiparous and 24 primiparous). Multiparous cows (mean ± SD = 6.4 ± 0.4 yr; BW = 589 ± 9.2 kg; BCS 6.2 ± 0.07) were used in both years of the experiment and primiparous cows (mean ± SD = 2.1 ± 0.04 yr of age, weighed 400 ± 7.5 kg and BSC of 5.6 ± 0.06) were only used in the first y≤ 0.10) to be less at 1400 and 1700 hr and were less (P = 0.05) at 1800 hr than CON heifers. Feeding OG did not result in changes (P = 0.25) in serum titer response to BVD virus of calves during year 2. The results of the current experiment indicate feeding OG to beef cows and calves can result in improvement in BCS of cows, enhance weight gain of calves preweaning, and reduce heat loads in heifer calves during the late summer. © The Author(s) 2020.

This study contributes to existing knowledge by employing a content analysis to examine visual and textual information on prescription medication websites. A stratified random sample was selected from a list of the 100 most-prescribed medications in the United States. Findings point to under-utilization of audiovisual components on the homepage of prescription medication websites as well as a lack of racial diversity in people pictured. Medications for chronic conditions were more likely to have homepages with a positive emotional tone than those for acute conditions. Further, more depictions of women on homepages predicted a greater number of prescriptions filled. This study includes implications for health education and healthcare professionals, patients and the Food and Drug Administration. � The Author(s) 2020. link3 Published by Oxford University Press.
