Muscle stem cells (MuSCs) persist in a quiescent state and activate in response to specific stimuli. The quiescent state is both actively maintained and dynamically regulated. However, analyses of quiescence have come primarily from cells removed from their niche. Although these cells are still quiescent, biochemical changes certainly occur during the isolation process. Here, we analyze the transcriptome of MuSCs in vivo utilizing MuSC-specific labeling of RNA. Notably, labeling transcripts during the isolation procedure revealed very active transcription of specific subsets of genes...

The volatile organic compounds (VOCs) are increasingly been recognized as the chemical mediators of mold interactions shaping their community dynamic, growth, and metabolism. Herein, we selectively examined the time-correlated (0 D - 11 D) effects of intra-species VOCs mediated interactions (VMI) on Aspergillus oryzae KCCM 60345 (S1), following co-cultivation with partner strain A. oryzae KACC 44967 (S2), in specially designed twin plate assembly. The comparative evaluation of S1VMI (S1 subjected to VMI with S2) and its control (S1con) showed a notable disparity in their radial growth (S1VMI<S1con) at 5 D, protease activity (S1VMI>S1con) at 3-5 D, amylase activity (S1VMI<S1con) at 3-5 D, and antioxidant levels (S1VMI>S1con) at 3 D...

A high-fat diet has been recognized as an important risk factor of obesity, with variable impacts of different fatty acid compositions on the physiological process. To understand the effects of a high-margarine/lard diet, which is a major source of trans fatty acids (TFAs)/ saturated fatty acids (SFAs), elaidic acid as a biomarker of margarine intake was used to screen affected adipokines on mature human adipocytes in vitro. Weaned male Wistar rats were fed a high-fat diet enriched with margarine/lard to generate obesity-prone (OP) and obesity-resistant (OR) models, which were then used to explore the inflammatory responses of depot-specific white adipose tissue...

Previous outbreaks suggest that pregnant women with Ebola virus disease (EVD) are at increased risk for severe disease and death. Healthcare workers who treat pregnant women with EVD are at increased risk of body fluid exposure. Despite the absence of pregnant women with EVD in the United States, CDC activated the Maternal Health Team (MHT), a functional unit dedicated to emergency preparedness and response issues, on October 18, 2014. We describe major activities of the MHT. A high-priority MHT activity was to publish guiding principles early in the response...

Human pluripotent stem cells (hPSCs) hold tremendous promise for regenerative medicine, disease modeling, toxicology screening, and developmental biology. These applications are hindered due to inherent differences in differentiation potential observed among different hPSC lines. This is particularly true for the differentiation of hPSCs toward the endodermal lineage. Several groups have developed methods to screen hPSCs for their endodermal differentiation potential (EP). Particularly notable studies include (i) the use of WNT3A expression as a predictive biomarker, (ii) an embryoid body-based screen, and (iii) a transcriptomics-based approach...

A practical and sustainable method for the synthesis of levocabastine hydrochloride (1), a H₁ receptor antagonist for the treatment of allergic conjunctivitis, that can be applied to the industrial production of the compound has been developed. Substantial improvements over the previously reported procedure are achieved via efficient preparation of an optically active key intermediate (5) without chiral resolution and with a more effective detosylation, which complements the previous procedure. Notably, our process requires no chromatographic purification and provides levocabastine hydrochloride in greater than 99...

Inflammation is a reaction of the host to infectious or sterile stimuli and has the physiological purpose of restoring tissue homeostasis. However, uncontrolled or unresolved inflammation can lead to tissue damage, giving rise to a plethora of chronic inflammatory diseases, including metabolic syndrome and autoimmunity pathologies with eventual loss of organ function. Beta-nitrostyrene and its derivatives are known to have several biological activities, including anti-edema, vasorelaxant, antiplatelet, anti-inflammatory, and anticancer...

Titin-related diseases of the skeletal and cardiac muscles open a new, fruitful chapter of myology. Confined for a long time to a limited number of clinical entities, the phenotypic spectrum of titinopthies is nowadays expanding rapidly together with the discovery of many pathogenic mutations of the TTN gene. Like for many genes of large size, the fine tuning and use of high-throughput sequencing (NGS) constitutes a little revolution in the field. This powerful tool allows, although with real technical hurdles, the establishment of the definite diagnosis of titinopathy...

Melanosuchus niger (Crocodylia, Alligatoroidea) is one of the six living caimanine species widely distributed throughout the Amazon River basin today. Although there is only one extant species of Melanosuchus, fossil material assigned to this genus, represented by M. fisheri, has been reported from the late Miocene in South America. However, the validity of this taxon has been questioned and a recent investigation indicates that the referred specimen of M. fisheri (MCZ 4336) actually belongs to Globidentosuchus brachyrostris, while those diagnostic characters present in the holotype (MCNC 243) fall into the spectrum of intraspecific variation of M...

Liver kinase B1 (LKB1) regulates a variety of cellular functions, including cell polarity, energy metabolism and cell growth, by targeting multiple signaling pathways such as AMPK/mTOR and p53. LKB1 functions as a tumor suppressor in sporadic cancers including lung cancer. Extracellular vesicles such as exosomes secreted by cancer cells modulate the tumor microenvironment and progression by targeting both tumor cells (autocrine actions) and other types of cells associated with tumors (paracrine actions). While the roles of LKB1 in cellular signaling in general is well-studied, its specific role in exosome-mediated signaling remains to be explored...

Tumor-initiating cells possess the capacity for self-renewal and to create heterogeneous cell lineages within a tumor. Therefore, the identification and isolation of cancer stem cells is an essential step in the analysis of their biology. The aim of the present study was to determine whether the cell surface protein neuropilin 1 (NRP1) can be used as a biomarker of stem-like cells in lung cancer tumors. For this purpose, NRP1-negative (NRP1-) and NRP1-positive (NRP1+) cell subpopulations from two lung cancer cell lines were sorted by flow cytometry...

The aim of the present study was to investigate the role of triglyceride metabolism in the effect of obstructive cholestasis on liver regeneration following 50% partial hepatectomy (PH). Obstructive cholestatic rat models were achieved via ligation of the common bile duct (BDL). Following comparisons between hepatic pathological alterations with patients with perihilar cholangiocarcinoma, rats in the 7 day post‑BDL group were selected as the BDL model for subsequent experiments. Liver weight restoration, proliferating cell nuclear antigen labeling index, cytokine and growth factor expression levels, and hepatic triglyceride content were evaluated to analyze liver regeneration post‑PH within BDL and control group rats...
