Loss of the anion exchanger DRA (Slc26a3), or PAT1 (Slc26a6), alters sulfate transport by the distal ileum and overall sulfate homeostasis.

The ileum is considered the primary site of inorganic sulfate ([Formula: see text]) absorption. In the present study, we explored the contributions of the apical chloride/bicarbonate (Cl-/[Formula: see text]) exchangers downregulated in adenoma (DRA; Slc26a3), and putative anion transporter 1 (PAT1; Slc26a6), to the underlying transport mechanism. Transepithelial 35[Formula: see text] and 36Cl- fluxes were determined across isolated, short-circuited segments of the distal ileum from wild-type (WT), DRA-knockout (KO), and PAT1-KO mice, together with measurements of urine and plasma sulfate. The WT distal ileum supported net sulfate absorption [197.37 ± 13.61 (SE) nmol·cm-2·h-1], but neither DRA nor PAT1 directly contributed to the unidirectional mucosal-to-serosal flux ([Formula: see text]), which was sensitive to serosal (but not mucosal) DIDS, dependent on Cl-, and regulated by cAMP. However, the absence of DRA significantly enhanced net sulfate absorption by one-third via a simultaneous rise in [Formula: see text] and a 30% reduction to the secretory serosal-to-mucosal flux ([Formula: see text]). We propose that DRA, together with PAT1, contributes to [Formula: see text] by mediating sulfate efflux across the apical membrane. Associated with increased ileal sulfate absorption in vitro, plasma sulfate was 61% greater, and urinary sulfate excretion (USO4) 2.2-fold higher, in DRA-KO mice compared with WT controls, whereas USO4 was increased 1.8-fold in PAT1-KO mice. These alterations to sulfate homeostasis could not be accounted for by any changes to renal sulfate handling suggesting that the source of this additional sulfate was intestinal. In summary, we characterized transepithelial sulfate fluxes across the mouse distal ileum demonstrating that DRA (and to a lesser extent, PAT1) secretes sulfate with significant implications for intestinal sulfate absorption and overall homeostasis.NEW & NOTEWORTHY Sulfate is an essential anion that is actively absorbed from the small intestine involving members of the Slc26 gene family. Here, we show that the main intestinal chloride transporter Slc26a3, known as downregulated in adenoma (DRA), also handles sulfate and contributes to its secretion into the lumen. In the absence of functional DRA (as in the disease congenital chloride diarrhea), net intestinal sulfate absorption was significantly enhanced resulting in substantial alterations to overall sulfate homeostasis.
Gender Differences in the Prevalence and Characteristics of Pain in Spain: Report from a Population-Based Study.

OBJECTIVE To assess the prevalence and characteristics of chronic neck pain, chronic low back pain, and migraine or frequent headaches among Spanish adults in 2014 according to gender, to identify predictors for each of these types of pains, and to compare the prevalence with those found in 2009. DESIGN Cross-sectional study. SETTING Spain. METHODS We used data collected from the 2014 European Health Interview Survey (N = 22,842). Sociodemographic features, self-rated health status, lifestyle habits, comorbid conditions, pain characteristics, and self-reported use of medications were analyzed. RESULTS The prevalence of all types of pain was significantly higher among women than men. For chronic neck pain, the figures were 25.68% vs 12.54%, for chronic low back pain, 27.03% vs 18.83%, and for migraine or frequent headaches, 15.93% vs 6.74%, in women and men, respectively. Predictors of these types of pain included female gender, advanced age, poor self-rated health, psychological distress, comorbidities, and obesity. The prevalence of neck pain and low back pain increased from 2009 to 2014 for both sexes, and the prevalence of migraine or frequent headaches remained stable over time. CONCLUSIONS The prevalence and intensity of all the forms of chronic pain were higher among women. Women experiencing pain used prescribed medications for pain, anxiety, and/or depression and sleeping pills more than men. The prevalence of chronic neck and low back has increased in the last five years in Spain, and the prevalence of migraine or frequent headaches has remained stable.
Simian Immunodeficiency Virus Infects Functionally Polarized Memory CD4 T Cells Equivalently In Vivo

Functional perturbations of memory CD4 T cells have been suggested to underlie important aspects of HIV disease progression. However, the mechanisms underlying these perturbations remain unclear. Using a nonhuman primate model of HIV, we show that SIV infects functionally defined populations of memory CD4 T cells equally in different anatomic sites. Thus, preferential infection by the virus is unlikely to cause functional perturbations. ABSTRACT Among the numerous immunological abnormalities observed in chronically human immunodeficiency virus (HIV)-infected individuals, perturbations in memory CD4 T cells are thought to contribute specifically to disease pathogenesis. Among these, functional imbalances in the frequencies of T regulatory cells (Tregs) and interleukin 17 (IL-17)/IL-22-producing Th cells (Th17/Th22) from mucosal sites and T follicular helper (Tfh) cells in lymph nodes are thought to facilitate specific aspects of disease pathogenesis. However, while preferential infection of Tfh cells is widely thought to create an important viral reservoir in an immunologically privileged site in vivo, whether immunological perturbations among memory CD4 T cell populations are attributable to their relative infectivity by the virus in vivo is unclear. Here we studied peripheral blood and lymphoid tissues from antiretroviral (ARV)-treated and ARV-naive Asian macaques and isolated functionally defined populations of memory CD4 T cells. We then assessed the degree to which these populations were infected by simian immunodeficiency virus (SIV) in vivo, to determine whether particular functionally identified populations of memory CD4 T cells were preferentially infected by the virus. We found that SIV did not preferentially infect Th17 cells, compared to Th1 cells, Th2 cells, or Tregs. Moreover, Th17 cells contributed proportionately to the total pool of infected cells. Taken together, our data suggest that, although Tfh cells are more prone to harbor viral DNA, other functionally polarized cells are equally infected by the virus in vivo and Th17 cells are not preferentially infected. IMPORTANCE Functional perturbations of memory CD4 T cells have been suggested to underlie important aspects of HIV disease progression. However, the mechanisms underlying these perturbations remain unclear. Using a nonhuman primate model of HIV, we show that SIV infects functionally defined populations of memory CD4 T cells equally in different anatomic sites. Thus, preferential infection by the virus is unlikely to cause functional perturbations.
Aqueous extracts of Syzygium brazzavillense can inhibit the infection with coxsackievirus B4 in vitro

Traditional practitioners commonly use plant crude extracts to treat various diseases in patients with symptoms that can be seen during enterovirus infections. In this study, the antienteroviral activity of medicinal plants from the Republic of Congo has been evaluated in vitro. Through an ethnopharmacological approach, seven plants grouped into six families were identified. Aqueous and organic extracts of various organs from these plants were prepared. The organic extracts at subcytotoxic concentrations did not inhibit the cytopathic effect (CPE) induced by coxsackievirus (CV)B1‐5, CVA6, poliovirus type 1, and enterovirus 71. The aqueous extract of Syzygium brazzavillense, but not those of other plants, inhibited the CPE induced by CVB3 and CVB4 at 30 µg/mL (CC50; 2800 µg/mL, IC50; 0.8 µg/mL) and by CVB2 and poliovirus type 1 at higher concentrations. When aqueous extract of this plant was mixed with CVB4, the replication of the virus was inhibited. In conclusion, aqueous extracts of Syzygium brazzavillense can inhibit the infection with CVB4 and other enteroviruses in vitro. The present ethnopharmacological investigation helped to identify a plant with potential properties useful to combat enterovirus infections.
Differential Translocation of the Fatty Acid Transporter, FAT/CD36, and the Glucose Transporter, GLUT4, Coordinates Changes in Cardiac Substrate Metabolism During Ischemia and Reperfusion

Background—Fatty acid and glucose transporters translocate between the sarcolemma and intracellular compartments to regulate substrate metabolism acutely. We hypothesised that during ischemia fatty acid translocase (FAT/CD36) would translocate away from the sarcolemma to limit fatty acid uptake when fatty acid oxidation is inhibited. Methods and Results—Wistar rat hearts were perfused during preischemia, low-flow ischemia, and reperfusion, using 3H-substrates for measurement of metabolic rates, followed by metabolomic analysis and subcellular fractionation. During ischemia, there was a 32% decrease in sarcolemmal FAT/CD36 accompanied by a 95% decrease in fatty acid oxidation rates, with no change in intramyocardial lipids. Concomitantly, the sarcolemmal content of the glucose transporter, GLUT4, increased by 90% during ischemia, associated with an 86% increase in glycolytic rates, 45% decrease in glycogen content, and a 3-fold increase in phosphorylated AMP-activated protein kinase. Following reperfusion, decreased sarcolemmal FAT/CD36 persisted, but fatty acid oxidation rates returned to preischemic levels, resulting in a 35% decrease in myocardial triglyceride content. Elevated sarcolemmal GLUT4 persisted during reperfusion; in contrast, glycolytic rates decreased to 30% of preischemic rates, accompanied by a 5-fold increase in intracellular citrate levels and restoration of glycogen content. Conclusions—During ischemia, FAT/CD36 moved away from the sarcolemma as GLUT4 moved toward the sarcolemma, associated with a shift from fatty acid oxidation to glycolysis, while intramyocardial lipid accumulation was prevented. This relocation was maintained during reperfusion, which was associated with replenishing glycogen stores as a priority, occurring at the expense of glycolysis and mediated by an increase in citrate levels.
Target-Directed Movements at a Comfortable Pace: Movement Duration and Fitts's Law

Although many studies have supported P. M. Fitts's (1954) law as a description of the speed-accuracy trade-off for speeded movements, there has been a lack of research regarding movement duration for target-directed movements made at any other pace. In the present study, the duration of movements made at a naturally selected comfortable pace and a quick pace differed from Fitts's law in a way that was similar to the predictions of participants in previous studies of naive motor decisions and imagined movements (S. J. Young, J. Pratt, & T. Chau, 2008; S. J. Young, J. Pratt, & T. Chau, 2009). These results show that movements of various speeds have predictable patterns of movement duration. The results also suggest that individuals adjust more than the implicit target size when changing their desired movement speed.
Comparison of breast cancer risk factors among molecular subtypes: A case‐only study

Epidemiological studies have a clear definition of the risk factors for breast cancer. However, it is unknown whether the distribution of these factors differs among breast cancer subtypes. We conducted a hospital‐based case‐only study consisting of 8067 breast cancer patients basing on the Tianjin Cohort of Breast Cancer Cases. Major breast cancer subtypes including luminal A, luminal B, human epidermal growth factor receptor 2 (HER2)‐enriched and basal‐like were defined by estrogen receptor, progesterone receptor, HER2, and Ki‐67 status. Variables including demographic characteristics, reproductive factors, lifestyle habits, imaging examination, and clinicopathologic data were collected for patients. Chi‐square test and one‐way analysis of variance were used to compare the distributions of variables among the four breast cancer subtypes. Multivariate logistic regression was used to estimate the odds ratios and associated 95% confidence intervals where luminal A patients served as the reference group. Overall, more commonality rather than heterogeneity on the distributions of factors was found between the four molecular subtypes of breast cancer. The proportion of overweight and obesity were lower in HER2‐enriched subtype. Women with age at menarche ≤13 years were more likely to be found in basal‐like subtype. Postmenopausal women were more frequent in HER2‐enriched and basal‐like subtypes. Women with benign breast disease and higher breast density were more common in HER2‐enriched subtype. Risk factor scoring showed that total risk scores were similar among the four subtypes. HER2‐enriched and basal‐like subtypes were more frequently diagnosed with large tumors. Calcification was more likely to be found in luminal B and HER2‐enriched subtypes, whereas less distributed in basal‐like subtype. Most of the breast cancer risk factors were similarly distributed among the four major breast cancer subtypes; commonality is predominant.
E-cigarettes and the clinical encounter: Physician perspectives on e-cigarette safety, effectiveness, and patient educational needs.

RATIONALE, AIMS, AND OBJECTIVES There is limited research on how health care providers approach the topic of e-cigarettes in clinical encounters, especially in conjunction with other best-practice recommendations for smoking cessation. This qualitative study explored physician perceptions and recommendations involving e-cigarettes in the context of smoking cessation counselling, including their opinions about the implementation and content of patient educational materials that focus on e-cigarettes. METHODS Semistructured interviews were conducted with 15 physicians from family medicine, internal medicine, and obstetrics/gynaecology (OB/GYN). RESULTS Physicians did not routinely assess e-cigarette use among patients and reported that discussions were often initiated by patients. Only a minority of participants discussed e-cigarettes in conjunction with other best-practice recommendations for smoking cessation. Most others were more ambivalent about e-cigarette safety and effectiveness for cessation and did not address the topic, unless patients were already using e-cigarettes. Almost all, however, agreed that more research on e-cigarettes was needed. Physicians expressed an interest in having enhanced discussions about e-cigarettes with their patients and in using patient educational materials to accomplish this. Physicians recommended that these materials not actively promote e-cigarettes and be tailored to patients based on their demographics and motivation to quit. CONCLUSIONS Physicians were open to improving their smoking cessation counselling and to integrating new patient educational materials that addressed e-cigarettes. Patient educational materials that provide tailored information about e-cigarettes could potentially be used initiate e-cigarette discussions and inform smokers about what is known vs unknown about e-cigarettes.

Abstract In this study, the complete mitochondrial genome of the fat-nose goby Pseudogobius javanicus has been amplified. P. javanicus is widely contributed species in Southeast to East Asia. The complete mitochondrial genome is 16,493 base pairs (bp) in total length, had the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 2 rRNAs, 22 tRNAs, 1 control region (CR) and 1 light-strand replication origin (OL). The overall base composition of P. javanicus is 27.1% for A, 27.3% for T, 28.6% for C, 17.0% for G, with higher AT content of 54.4%. This study will contribute for understanding the phylogenetic approach in genus Pseudogobius.
The Anti-Tumor Agent Sodium Selenate Decreases Methylated PP2A, Increases GSK3βY216 Phosphorylation, Including Tau Disease Epitopes and Reduces Neuronal Excitability in SHSY-5Y Neurons

Selenium application as sodium selenate was repeatedly shown to have anti-carcinogenic properties by increasing levels of the serine/ threonine protein phosphatase 2A (PP2A) in cancer cells. PP2A has a prominent role in cell development, homeostasis, and in neurons regulates excitability. PP2A, GSK3β and Tau reside together in a complex, which facilitates their interaction and (dys)-function as has been reported for several neurological disorders. In this study we recorded maximum increase in total PP2A at 3 µM sodium selenate in a neuron cell line. In conjunction with these data, whole-cell electrophysiological studies revealed that this concentration had maximum effect on membrane potentials, conductance and currents. Somewhat surprisingly, the catalytically active form, methylated PP2A (mePP2A) was significantly decreased. In close correlation to these data, the phosphorylation state of two substrate proteins, sensitive to PP2A activity, GSK3β and Tau were found to be increased. In summary, our data reveal that sodium selenate enhances PP2A levels, but reduces catalytic activity of PP2A in a dose dependent manner, which fails to reduce Tau and GSK3β phosphorylation under physiological conditions, indicating an alternative route in the rescue of cell pathology in neurological disorders.
Possible molecular mechanisms of glucose‐lowering activities of Momordica charantia (karela) in diabetes

Diabetes mellitus is a highly prevalent metabolic disorder which is characterized by impaired glucose tolerance, with a relative or absolute insulin deficiency and profound changes in the metabolism of macronutrients. Traditional and complementary medicine is therapeutic strategies that have both been applied to improving glycemic control. Momordica charantia is one of the plant‐based, folk medicines that used for improving glycemic control. We aimed to review, the effects of M. charantia on blood glucose with a clarification of the molecular pathways involved. Of the compounds derived from the plants, the insulin‐like peptide, charantin, and the alkaloid vicine, have been reported to have hypoglycemic effects. Different mechanisms contribute to the antidiabetic activities of M. charantia, these include increasing pancreatic insulin secretion, decreasing insulin resistance and increasing peripheral and skeletal muscle cell glucose utilization, inhibition of intestinal glucose absorption and suppressing of key enzymes in the gluconeogenic pathways.
Production , Manufacturing and Logistics Managing supply chain backorders under vendor managed inventory : An incentive approach and empirical analysis

This paper shows how a manufacturer may use an incentive contract with a distributor under a VMI arrangement to gain market share. The manufacturer promises a distributor lower inventory levels in exchange for efforts by the distributor to convert potential lost sales due to stockouts to backorders. Data gathered from a third party provider of information services are then used to illustrate that this incentive arrangement may, at least implicitly, be employed in industry. Our data estimations show that when a manufacturer and distributor are operating under a VMI arrangement, lower inventory at the distributor is associated with a higher conversion rate of lost sales stockouts to backorders. 2009 Elsevier B.V.

Long-Term Outcomes after Surgical Resection for Synchronous or Metachronous Hepatic and Pulmonary Colorectal Cancer Metastases

Background/Aims: At present, benefits of surgical resection and appropriate selection criteria in patients affected by both hepatic and pulmonary metastases of colorectal cancer (CRC) are under discussion. Our analysis focused on a surgical series of such patients and our final aim consisted in identifying potential prognostic factors. Methods: Eighty-five patients undergoing resection of both hepatic and pulmonary metastases at 2 Healthcare Institutions from January 1993 to June 2015 were retrospectively reviewed as concerned clinical information, surgical notes and pathological features. Patient, treatment, and outcome variables were analyzed by use of log-rank tests, Cox regression, and Kaplan-Meier methods. Results: Liver turned out as the first site of metastasis in 75% patients, lung in 13% patients, and both sites in 12% patients. Multiple hepatic metastases were detected in 67% patients and pulmonary metastases in 31% patients. Two hundred eighteen surgical interventions were performed (mean 2.56 for each patient). Overall survival (OS) rates at 3-, 5-, and 10-year follow-up from colorectal resection were 94, 79, and 38% respectively. Median OS was 8.31 years. Survival turned out significantly longer for patients with disease-free interval (DFI) exceeding 1 year between first metastasectomy and diagnosis of second metastases and in patients affected by metachronous pulmonary metastases. Conclusions: Surgical resection of both hepatic and pulmonary metastases of CRC represents a safe and effective treatment. It might lead to rewarding long-term survival rates in high selected patients. Shorter DFIs between first metastasectomy and diagnosis of second metastases can determine worse prognoses. In addition, poor outcomes could be predicted also for patients affected by synchronously detected pulmonary CRC metastases, although further confirmatory analyses are strongly required.
Relative Expression of OX40, OX40L mRNA, and OX40L Serum Levels in Women with Recurrent Spontaneous Abortion

ABSTRACT This study determined the roles of OX40 and OX40L in women with recurrent spontaneous abortion (RSA). We compared the expression of OX40 and OX40L genes in peripheral blood mRNA levels and serum levels of OX40L in women with a history of RSA to the control group. In this case-control study, 40 women with a history of RSA (case group), and 40 others with no history of abortion (control group) were investigated. The expressions of OX40 mRNA and OX40L mRNA were determined in the two groups using the quantitative polymerase chain reaction. Also, the enzyme-linked immunosorbent assay was used to determine the levels of serum OX40L in the two groups. There were no significant differences in the maternal age of women in the two groups (30.1 ± 4.28 years in the case vs. 30.03 ± 4.23 years in the control group). There was no difference in terms of the levels of OX40 and OX40L mRNA between the groups (p = 0.08 and p = 0.56, respectively). In addition, there was no significant correlation between the expression of OX40 and OX40L mRNA levels with age or the number of abortions. The correlation between OX40 and OX40L mRNA levels was not significant. RSA history group turned to show a higher level of serum OX40L than the control group (p = 0.03). In conclusion, our findings demonstrated that the expression of OX40 mRNA and OX40L mRNA was similar between women with a history of RSA and the control group. The elevation of serum OX40L level may be considered as a risk factor for RSA.
