Colistin is a last resort antibiotic to treat multidrug-resistant Gram-negative bacteria infections. Colistin is administered intravenously in the form of its inactive prodrug colistin methanesulfonate (CMS). For patients with acute kidney impairment and continuous renal replacement therapy high extracorporeal clearance may cause a substantial removal of active colistin from the bloodstream, eventually decreasing its antibacterial efficacy. Currently recommended doses of CMS may therefore be inadequate for these patients...

The in vivo model of pollinosis has been established using rodents, but the model cannot completely mimic human pollinosis. We used Callithrix jacchus, the common marmoset (CM), to establish a pollinosis animal model using intranasal weekly administration of cedar pollen extract with cholera toxin adjuvant. Some of the treated CMs exhibited the symptoms of snitching, excess nasal mucus and/or sneezing, but the period was very short, and the symptoms disappeared after several weeks. The CD4+CD25+ cell ratio in the peripheral blood increased in CMs quickly after the nasal administration of cedar pollen extract, but the timing was not parallel with the symptoms...

Latest outcomes assign functional role to non-coding (nc) RNA molecules in regulatory networks that confer male sterility to plants. Male sterility in plants offers great opportunity for improving crop performance through application of hybrid technology. In this respect, cytoplasmic male sterility (CMS) and sterility induced by photoperiod (PGMS)/temperature (TGMS) have greatly facilitated development of high-yielding hybrids in crops. Participation of non-coding (nc) RNA molecules in plant reproductive development is increasingly becoming evident...

BACKGROUND: Intracranial (cavernous malformations) CMs are usually located at the cerebral parenchyma, dural-based CMs outside the middle fossa are rarely reported. To our knowledge, dural-based CMs located at the cerebral convexity are even rarer that only two pediatric cases were ever reported. In this report, we present two extremely rare cases of dural-based CMs at the cerebral convexity in pediatric patients. The clinical course, radiological and pathological features, treatment, and follow-up are described...

STUDY DESIGN: Randomized clinical trial. INTRODUCTION: Eccentric exercise (EE) was shown to be an effective treatment in tendinopathies. However, the evidence of its effectiveness in subacromial syndrome (SS) is scarce. Moreover, consensus has not been reached on whether best results for SS are obtained by means of EE with or without pain. PURPOSE OF THE STUDY: The purpose of this is to compare the effect on pain, active range of motion (AROM), and shoulder function of an exercise protocol performed with pain <40 mm Visual Analog Scale (VAS) and without pain, in patients with SS...

INTRODUCTION: Chordoid meningiomas (CMs) are a rare subgroup of tumors, accounting for approximately 0.5% of all meningiomas. These tumors correspond to World Health Organization (WHO) Grade II lesions and behave aggressively, with an increased likelihood of recurrence. There are only two studies that have described the genetic alterations in CMs. While a majority of meningiomas are known to have deletion at many chromosomal loci such as 22q, 18p, 14q, and 1p, which are found to be associated with initiation, progression, and malignancy of these tumors, these have not yet been studied in CMs...

INTRODUCTION AND HYPOTHESIS: We investigated the protective effect and underlying molecular mechanism of nuclear factor-E2-related factor 2 (Nrf2) against mechanical-stretch-induced apoptosis in mouse fibroblasts. METHODS: Normal cells, Nrf2 silencing cells, and Nrf2 overexpressing cells were respectively divided into two groups-nonintervention and cyclic mechanical strain (CMS)-subjected to CMS of 5333 μ (1.0 Hz for 4 h), six groups in total (control, CMS, shNfe212, shNfe212 + CMS, LV-shNfe212, and LV-shNfe212 + CMS)...

Here, we find that human-induced pluripotent stem cell (hiPSC)-derived cardiomyocyte (CM)-fated progenitors (CFPs) that express a tetraspanin family glycoprotein, CD82, almost exclusively differentiate into CMs both in vitro and in vivo. CD82 is transiently expressed in late-stage mesoderm cells during hiPSC differentiation. Purified CD82+ cells gave rise to CMs under nonspecific in vitro culture conditions with serum, as well as in vivo after transplantation to the subrenal space or injured hearts in mice, indicating that CD82 successfully marks CFPs...

BACKGROUND: The Center for Medicare and Medicaid Services (CMS) and the Hospital Quality Alliance began collecting and reporting United States hospital performance in the treatment of pneumonia and heart failure in 2008. Whether the utilization of hospice might affect CMS-reported mortality and readmission rates is not known. METHODS: Hospice utilization (mean days on hospice per decedent) for 2012 from the Dartmouth Atlas (a project of the Dartmouth Institute that reports a variety of public health and policy-related statistics) was merged with hospital-level 30-day mortality and readmission rates for pneumonia and heart failure from CMS...

Congenital myasthenic syndromes (CMS) are a group of rare disorders that cause fatigable muscle weakness due to defective signal transmission at the neuromuscular junction, a specialized synapse between peripheral motor neurons and their target muscle fibers. There are now over 30 causative genes that have been reported for CMS. Of these, there are 10 that are associated with a limb-girdle pattern of muscle weakness and are thus classed as LG-CMS. Next-generation sequencing and advanced methods of data sharing are likely to uncover further genes that are associated with similar clinical phenotypes, contributing to better diagnosis and effective treatment of LG-CMS patients...

High prevalence of extensive-drug resistance (XDR) gram-negative pathogens has forced clinicians to use colistin as the last-line therapy. Our knowledge on the pharmacokinetics (PK) of colistin methanesulfonate (CMS, an inactive prodrug) and colistin has increased substantially; however, the PK in Chinese population is still unknown due to the lack of a CMS product. This study aimed to evaluate the PK of a new CMS product developed in China for optimizing the dosing regimens. Twenty-four healthy subjects (12 female, 12 male) were enrolled in single- and multiple-dose PK studies...

Colorectal cancer (CRC) is a highly heterogeneous disease both from a molecular and clinical perspective. Several distinct molecular entities, such as microsatellite instability (MSI), have been defined that make up biologically distinct subgroups with their own clinical course. Recent data indicated that CRC can be best segregated into four groups called consensus molecular subtypes (CMS1-4), each of which has a unique biology and gene expression pattern. In order to develop improved, subtype-specific therapies and to gain insight into the molecular wiring and origin of these subtypes, reliable models are needed...

Trastuzumab (Herceptin®), a monoclonal antibody against the ErbB2 (HER2) receptor, has significantly improved clinical outcomes for HER2+ breast cancer patients. However, the drug also has known cardiotoxic side effects through mechanisms that are not fully understood. Here we utilized human induced pluripotent stem cell-derived cardiomyocytes (iPS-CMs) to model trastuzumab-related cardiotoxicity in vitro. We demonstrate that cardiotoxic effects of ErbB2 inhibition by trastuzumab can be recapitulated only when the cardioprotective effects of ErbB2/4 signaling is observed...

Cytoplasmic male sterility (CMS) is primarily caused by chimeric genes located in the mitochondrial genomes. In Brassica juncea, orf288 has been identified as a CMS-associated gene in the hau CMS line; however, neither the specific abortive stage nor the molecular function of the gene have been determined. We therefore characterized the hau CMS line, and found that defective mitochondria affect the development of archesporial cells during the L2 stage, leading to male sterility. The expression level of the orf288 transcript was higher in the male-sterility line than in the fertility-restorer line, although no significant differences were apparent at the protein level...

Healthcare systems are receiving increasing pressures from payers, such as the Centers for Medicare and Medicaid (CMS), to reduce the costs associated with procedures, and with the implementation of the Affordable Care Act, high costs are addressed through pay-for-performance programs. Thus, multiple areas of total knee arthroplasty (TKA) surgery are under scrutiny, including surgical times, material costs, and the costs of associated complications and readmissions. Suture type has been determined to be a factor that may influence closure times, as well as direct material costs...

BACKGROUND: The demand for conversion of prior hip surgery to total hip arthroplasty (conversion THA) is likely to increase as a function of increasing US hip fracture burden in addition to its application in managing other conditions. Thus, outcome analysis is warranted to better inform value-based reimbursement schemes in the era of bundled payments. METHODS: Via Current Procedural Terminology codes, the National Surgical Quality Improvement Project data files were queried for all patients who underwent primary THA and conversion of previous hip surgery to THA from 2005 to 2014...

BACKGROUND: Cytoplasmic male sterility (CMS) is a maternally inherited trait failing to produce functional pollen. It plays a pivotal role in the exploitation of crop heterosis. The specific locus amplified fragment sequencing (SLAF-seq) as a high-resolution strategy for the identification of new SNPs on a large-scale is gradually applied for functional gene mining. The current study combined the bulked segregant analysis (BSA) with SLAF-seq to identify the candidate genes associated with fertility restorer gene (Rf) in CMS cotton...
