BACKGROUND: For T1D patients, adding metformin to insulin therapies is thought to improve blood glucose levels, but current evidence does not support this clinical benefit. Additional data from large clinical trials are now available; therefore, we conducted a meta-analysis of studies on assessing the efficacy and adverse effects of metformin. METHODS: We searched the MEDLINE, EMBASE and Cochrane Library databases for data from randomized controlled trials (RCTs)...

Background: Leptin is a nutritional hormone whose production is generally higher in females. We investigated how leptin is associated with sex dimorphism during urinary schistosomiasis in relation with wasting. Methods: A cross-sectional study was carried out in three villages in northern Senegal. Ninety-eight school-aged children belonging to the Fulani or Wolof villages were enrolled. We performed parasitic diagnosis and anthropometric measurement to evaluate nutritional status...

Background and Aims: Roots facilitate acquisition of macro- and micronutrients, which are crucial for plant productivity and anchorage in the soil. Phosphorus (P) is rapidly immobilized in the soil and hardly available for plants. Adaptation to P scarcity relies on changes in root morphology towards rooting systems well suited for topsoil foraging. Root-system architecture (RSA) defines the spatial organization of the network comprising primary, lateral and stem-derived roots and is important for adaptation to stress conditions...

Hypertensive disease of pregnancy (HDP) with placental insufficiency is the most common cause of fetal growth restriction (FGR) in the developed world. Despite the known negative consequences of HDP both to the mother and fetus, little is known about the longitudinal placental changes that occur as HDP progresses in pregnancy. This is because longitudinal sampling of human placentae during each gestation is impossible. Therefore, using a mouse model of thromboxane A2-analog infusion to mimic human HDP in the last trimester, we calculated placental efficiencies based on fetal and placental weights, quantified spongiotrophoblast and labyrinth thicknesses and vascular density within these layers, examined whether hypoxia signaling pathway involving vascular endothelial growth factor A (VEGFA) and its receptors (VEGFR1, VEGFR2) and matrix metalloproteinases (MMPs) contributed to vascular change, and examined nutrient transporter abundance including glucose transporters 1 and 3 (GLUT1, GLUT3), neutral amino acid transporters 1, 2, and 4 (SNAT1, SNAT2, and SNAT4), fatty acid transporters 2 and 4 (FATP2, FATP4) and fatty acid translocase (CD36) from embryonic day 15...

BACKGROUND: Globally, steatosis is the commonest type of liver pathology and is closely associated with obesity and the metabolic syndrome. Obesity is common in urban African females but no data is available on hepatic fat content in this population group when compared to other ethnic groups. The aim of this study was therefore to compare hepatic fat content in woman from different ethnic groups in South Africa and to characterise the principle determinants of liver fat. MATERIALS AND METHODS: A convenience sample of 106 (48 Indian, 29 African and 29 Caucasian) female volunteers aged 20-60 years and having no history of cardiometabolic disorders were recruited...

PURPOSE: Higher background parenchymal enhancement (BPE) could be used for stratification of MRI screening programs since it might be related to a higher breast cancer risk. Therefore, the purpose of this study is to correlate BPE to patient and tumor characteristics in women with unilateral MRI-screen detected breast cancer who participated in an intermediate and high risk screening program. As BPE in the affected breast may be difficult to discern from enhancing cancer, we assumed that BPE in the contralateral breast is a representative measure for BPE in women with unilateral breast cancer...

RATIONALE AND OBJECTIVES: The oral cavity is united with the airways, and thus poor oral health may affect respiratory health. However, data on the interaction of periodontal and respiratory health is limited. We aimed to evaluate whether periodontal health status, assessed by the Community Periodontal Index (CPI), was related to lung function among young and middle-aged adults in two Norwegian cohorts. METHODS: Periodontal health status and lung function were measured among 656 participants in the Norwegian part of the European Community Respiratory Health Survey (ECHRS III) and the RHINESSA offspring study...

The purpose of this study was to describe the experiences of fathers with scleroderma. Ten fathers with scleroderma were interviewed by telephone. Interviews were tape-recorded and transcribed verbatim. Two key themes emerged related to the emotional impact of the illness and the day to day realities of the illness with the unpredictability and rareness of the illness leading to ongoing feelings of isolation and fear of mortality. The negative influences of being a father with scleroderma included the inability of the fathers to participate in physical activities with their children such as outdoor sports and throwing balls...

The aim of this study was to investigate of psychometric properties of the Caregiver Difficulties Scale (CDS) for Iranian caregivers of children with cerebral palsy (CP). After a forward-backward translation, the Persian version of CDS (P-CDS) was administered to 151 Iranian mothers of CP children. The confirmatory factor analysis (CFA) was applied to measure the factor structure of P-CDS. The reliability was evaluated by examining internal consistency and test-retest method over a 2-week period using Cronbach's alpha and the intraclass correlation coefficient (ICC), respectively...

Interprofessional collaborative practice is critical for quality service delivery. Given the limited research on speech-language pathology (SLP) students' interprofessional knowledge and skills, this investigation assessed graduate SLP students' self-perceived interprofessional competence and their perceptions of roles of other professionals. Fifty-eight SLP students completed two validated surveys at the beginning of the first or second semester of graduate school. Collectively, the students rated themselves positively on communication, teamwork, attitudes toward interprofessional learning, and professional relationships...

An increased contribution of de novo lipogenesis (DNL) may play a role in cases of dyslipidemia and adipose accretion, this suggests that inhibition of fatty acid synthesis may affect clinical phenotypes. Since it is not clear whether modulation of one step in the lipogenic pathway is more important than another, the use of tracer methods can provide a deeper level of insight regarding the control of metabolic activity. Although [2H]water is generally considered a reliable tracer for quantifying DNL in vivo (it yields a homogenous and quantifiable precursor labeling), the relatively long half-life of body water is thought to limit the ability of performing repeat studies in the same subjects; this can create a bottleneck in the development and evaluation of novel therapeutics for inhibiting DNL...

DOCA-salt and obesity-related hypertension are associated with inflammation and sympathetic nervous system hyperactivity. Prejunctional α2-adrenergic receptors (α2ARs) provide negative feedback to norepinephrine release from sympathetic nerves through inhibition of N-type Ca2+ channels. Increased neuronal norepinephrine release in DOCA-salt and obesity-related hypertension occurs through impaired α2AR signaling, however, the mechanisms involved are unclear. Mesenteric arteries are resistance arteries that receive sympathetic innervation from the superior mesenteric and celiac ganglia (SMCG)...

It has become clear that the vasoactive peptide angiotensin II, like other so-called intracrines, can act in the intracellular space. Evidence has accumulated indicating that such angiotensin II activity can be upregulated in disease states and cause pathology. Indeed, other intracrines appear to be involved in disease pathogenesis as well. At the same time nitric oxide, potentially a cell protective factor, has been shown to be upregulated by intracellular angiotensin II. Recently data has been developed indicating that other potentially protective factors are directly upregulated at neuronal nuclei by angiotensin II...

Fibroblasts are thought to be the prime cell type for producing and secreting extracellular matrix (ECM) proteins in the connective tissue. The profibrotic cytokine, transforming growth factor-beta 1 (TGFβ1) activates and transdifferentiates fibroblasts into αSMA-expressing myofibroblasts, which exhibit increased ECM secretion, in particular collagens. Little information, however, exists about cell-surface molecules on fibroblasts that mediate this transdifferentiation process. We recently identified, using unbiased cell-surface proteome analysis, Cub domain containing protein 1 (CDCP1) to be strongly downregulated by TGFβ1...

Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator of leptin receptor signalling and may contribute to leptin resistance in diet-induced obesity. Although PTP1B inhibition has been suggested as a potential weight loss therapy, the role of specific neuronal PTP1B signalling in cardiovascular and metabolic regulation and the importance of sex differences in this regulation are still unclear. In this study, we investigated the impact of pro-opiomelanocortin (POMC) neuronal PTP1B deficiency in cardiometabolic regulation in male and female mice fed a high fat diet (HFD)...

We determined the impact of moderate maternal nutrient restriction (MNR) in guinea pigs with fetal growth restriction (FGR) on offspring body and organ weights, hypothesizing that FGR-MNR animals will show catch-up growth, but with organ-specific differences. Guinea pig sows were fed ad libitum (Control) or 70% of the control diet from 4 week`s pre-conception, switching to 90% at mid-pregnancy (MNR). Control newborns >95g (appropriate for gestational age or AGA, N=37) and MNR newborns <85g (FGR, N=37) were monitored until neonatal (~25 days) or adult (~110 days) necropsy...

MiR-199a is a novel gene regulator with an important role in inflammation and lung injury. However, its role in the pathogenesis of sepsis-induced acute respiratory distress syndrome (ARDS) is currently unknown. Our study explored the role of miR-199a in sepsis-induced ARDS and its mechanism of action. First, we found that LPS could up-regulate miR-199a in alveolar macrophages. Down-regulation of miR-199a inhibited the up-regulation of inflammatory cytokines in alveolar macrophages and induced the remission of histopathologic changes, the reduction of pro-inflammatory cytokines, and the up-regulation of apoptosis protein expression in an ARDS lung, showing a protective role for miR-199a...
