Tetrandrine, a bisbenzylisoquinoline alkaloid constituent of the root of Stephania tetrandra S. Moore, was previously shown to suppress the differentiation of T helper 17 (Th17) cells and consequently ameliorate the collagen-induced arthritis (CIA) in mice by activating the aryl hydrocarbon receptor (AhR), but its underlying mechanism is incompletely understood. Here, we investigated how tetrandrine suppressed Th17 cell differentiation through the AhR pathway. The naïve CD4(+) T cells were stimulated with anti-CD3/CD28 for 72 hrs in the presence or absence of tetrandrine under the Th17-polarizing condition...

BACKGROUND: β-catenin is a key component of the canonical Wnt pathway, which plays pivotal roles in malignant transformation and cancer progression. Several studies have reported the clinical significance of the expression level of β-catenin in different subcellular locations. This meta-analysis aimed to assess the prognostic value of β-catenin expression patterns in patients with non-small cell lung cancer (NSCLC). METHODS: PubMed and Embase databases were searched to identify all articles referring to the association between β-catenin expression level and outcomes of patients of NSCLC up to November 2016...

Background. Acute diarrhea is one of the leading causes of childhood mortality, with rotavirus being an important pathogen. Nitazoxanide, an antiparasitic agent, has been shown to inhibit rotavirus. Objective. This double-blind, randomized trial was designed to study the role of nitazoxanide in acute rotavirus diarrhea. Methods. Of 174 children (12 months to 5 years) with acute diarrhea, 50 rotavirus positive cases were randomized. The intervention group received syrup nitazoxanide twice daily (100 mg in 12-47 months, 200 mg in ≥4 yr) for 3 days along with standard treatment of diarrhea...

Despite the effects of insulinopenia in type 1 diabetes and evidence that insulin stimulates multiple renal sodium transporters, it is not known whether normal variation in plasma insulin regulates sodium homeostasis physiologically. This study tested whether the normal postprandial increase in plasma insulin significantly attenuates renal sodium and volume losses. Rats were instrumented with chronic artery and vein catheters, housed in metabolic cages, and connected to hydraulic swivels. Measurements of urine volume and sodium excretion (UNaV) over 24 hrs and the 4-hr postprandial period were made in Control (C) rats and Insulin-Clamped (IC) rats in which the postprandial increase in insulin was prevented...

BACKGROUND: Despite extensive study on hemoglobins and hemocyanins, little is known about hemerythrin (Hr) evolutionary history. Four subgroups of Hrs have been documented, including: circulating Hr (cHr), myohemerythrin (myoHr), ovohemerythrin (ovoHr), and neurohemerythrin (nHr). Annelids have the greatest diversity of oxygen carrying proteins among animals and are the only phylum in which all Hr subgroups have been documented. To examine Hr diversity in annelids and to further understand evolution of Hrs, we employed approaches to survey annelid transcriptomes in silico...

Objectives: Growth mixture modeling (GMM) combines latent growth curve and mixture modeling approaches and is typically used to identify discrete trajectories following major life stressors (MLS). However, GMM is often applied to data that does not meet the statistical assumptions of the model (e.g., within-class normality) and researchers often do not test additional model constraints (e.g., homogeneity of variance across classes), which can lead to incorrect conclusions regarding the number and nature of the trajectories...

Several previously published studies revealed a hazardous role of pretreatment lactate dehydrogenase (LDH) in survival of advanced or metastatic pancreatic cancer (PC) patients. Nevertheless, in early stage PC patients who are eligible for curative resection, the prognostic role of postresection LDH has never been discussed. In this study, we aimed to explore the prognostic significance of varying postresection LDH among early stage PC patients. In total, 80 PC patients who received curative resection were retrospectively selected from a population-based electronic inpatients database which originated from Shanghai, China...

Vascular endothelial growth factor (VEGF) plays an important role in angiogenesis and progression of cancer and its expression was associated with gene polymorphisms. Since the impact of polymorphisms of the VEGF on non-Hodgkin lymphoma prognosis has not been fully elucidated, we investigated 149 diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) at the National Cancer Center, Korea. Five polymorphisms were analyzed with clinical characteristics as well as international prognostic index (IPI)...

Insulin-like growth factor-I (IGF-I) is involved in the maturation and maintenance of neurons, and impaired IGF-I signaling has been shown to play a role in various neurological diseases including stroke. The aim of the present study was to investigate the efficacy of an optimized IGF-I variant by adding a 40 kDa polyethylene glycol (PEG) chain to IGF-I to form PEG-IGF-I. We show that PEG-IGF-I has a slower clearance which allows for twice-weekly dosing to maintain steady-state serum levels in mice. Using a photothrombotic model of focal stroke, dosing from 3 hrs post-stroke dose-dependently (0...

Disturbed sleep has become more common in recent years. To improve the quality of sleep, undergoing sleep observation has gained interest as a means to resolve possible problems. In this paper, we evaluate a non-restrictive and non-contact method for classifying real-time sleep stages and report on its potential applications. The proposed system measures heart rate (HR), heart rate variability (HRV), body movements, and respiratory signals of a sleeping person using two 24-GHz microwave radars placed beneath the mattress...

Context and Objective: Compared to the general population, hemodialysis patients have a substantially higher risk of hypothyroidism, as defined by an elevated serum thyrotropin (TSH) level, and cardiovascular mortality. Whereas an elevated serum TSH is associated with cardiovascular disease and death in the general population, these associations among dialysis patients have been inconsistent. Design, Setting, Participants, and Main Outcome: We examined 541 hemodialysis patients from 17 Southern California dialysis centers in the prospective Hypothyroidism, Cardiovascular Health, and Survival (HyCARDS) study who underwent protocolized measurement of repeated serum TSH levels every six months from May 2013 to August 2015...

The acute effects of PTH on FGF23 in vivo are not well understood. After a single s.c. PTH(1-34) injection (50nmol/kg) in mice, FGF23 levels were assessed in plasma using assays that measure either intact alone (iFGF23) or intact/C-terminal FGF23 (cFGF23). Furthermore, FGF23 mRNA and protein levels were assessed in bone. In addition, we examined the effects of PTH treatment on FGF23 production in vitro using differentiated calvarial osteocyte-like cells. cFGF23 levels increased by 3-5-fold within two hours following PTH injection, which returned to baseline by 4 hours...

The glymphatic pathway is a system which facilitates continuous cerebrospinal fluid (CSF) and interstitial fluid (ISF) exchange and plays a key role in removing waste products from the rodent brain. Dysfunction of the glymphatic pathway may be implicated in the pathophysiology of Alzheimer's disease. Intriguingly, the glymphatic system is most active during deep wave sleep general anesthesia. By using paramagnetic tracers administered into CSF of rodents, we previously showed the utility of MRI in characterizing a macroscopic whole brain view of glymphatic transport but we have yet to define and visualize the specific flow patterns...

Background/Aims. The miRNA-200 (miR-200) family may act as key inhibitors of epithelial-to-mesenchymal transition. However, the potential prognostic value of miR-200s in various human malignancies remains controversial. This meta-analysis analyzed the associations between miR-200 levels and survival outcomes in a variety of tumors. Methods. Eligible published studies were identified by searching the Embase, PubMed, CINAHL, and Google scholar databases. Patient clinical data were pooled, and pooled hazard ratios (HRs) with 95% confidence intervals (95% CI) were used to calculate the strength of this association...

OBJECTIVE: Among adults with type 2 diabetes (T2D), several (but not all) studies show that being overweight (body mass index (BMI): 25.0-29.9 kg/m(2)) or obese I (BMI: 30.0-34.9 kg/m(2)) near the time of diagnosis, is unexpectedly associated with reduced all-cause mortality compared with normal weight-the obesity paradox. We addressed whether this observation is causal (eg, a true protective effect); due to confounding (including effect modification); or due to selection ('collider') bias...

OBJECTIVE: A high body mass index (BMI) is associated with an increased risk for severe liver disease. It is unclear if this risk differs across BMI categories, and if the association is partially attributed to development of type 2 diabetes mellitus (T2DM). DESIGN: We used register data from more than 1.2 million Swedish men enlisted for conscription between 1969 and 1996. Data regarding new events of severe liver disease and T2DM during follow-up were obtained by record-linkage of population-based registers...
