BACKGROUND: Single-nucleotide polymorphisms (SNPs), which are located in the first intron of the FTO gene, are reported to be associated with body weight and the body mass index (BMI). However, their effects on anthropometric measurements in adolescents are poorly understood. OBJECTIVE: This study aimed to investigate the association of three adjacent polymorphisms (rs9930506, rs9930501, & rs9932754) in the FTO gene with anthropometric indices in Iranian adolescent males...

Intrinsic and adaptive resistance hamper the success of anti-angiogenic therapies (AAT), especially in breast cancer where this treatment modality has proven largely ineffective. Therefore, novel strategies to improve the efficacy of AAT are warranted. Solid tumors such as breast cancer are characterized by a high infiltration of myeloid-derived suppressor cells (MDSC) which are key drivers of resistance to AAT. Therefore, we hypothesized that all-trans retinoic acid (ATRA), which induces differentiation of MDSC into mature cells, could improve the therapeutic effect of AAT...

OBJECTIVES: Environmental enteropathy (EE) is likely associated with growth retardation in children, but the association between EE and length velocity z-score (LVZ) has not been investigated. The objective of the study was to assess associations between fecal markers for intestinal inflammation and LVZ and whether these associations were influenced by micronutrient adequacy among 9-24 months old children in Bhaktapur, Nepal. METHODS: Data was divided into 5 time slots (9-12, 12-15, 15-18, 18-21 and 21-24 months)...

Alpha-1 antitrypsin (AAT) is the most abundant serine protease inhibitor circulating in the blood. AAT deficiency (AATD) is an autosomal codominant condition affecting an estimated 3.4 million individuals worldwide. The clinical disease associated with AATD can present in a number of ways including COPD, liver disease, panniculitis and antineutrophil cytoplasmic antibody vasculitis. AATD is the only proven genetic risk factor for the development of COPD, and deficient individuals who smoke are disposed to more aggressive disease...

INTRODUCTION: Alpha 1-antitrypsin deficiency (AATD) is a genetic disorder which reduces serum alpha 1-antitrypsin (AAT or alpha1-proteinase inhibitor, A1PI) and increases the risk of chronic obstructive pulmonary disease (COPD). Management strategies include intravenous A1PI augmentation, and, in some cases, a health management program (Prolastin Direct® ; PD). OBJECTIVES: This study compared clinical and economic outcomes between patients with and without PD program participation...

Eating behavior in obesity resembles addictive disorders in that individuals have difficulties inhibiting problematic eating behavior. They show an approach bias - a tendency to approach rather than avoid problematic stimuli. Here, we investigate the existence of such a bias towards healthy and unhealthy food in individuals with normal-weight and obesity. We further aimed to assess whether it is possible to retrain a bias, and whether training would differentially affect our two weight groups. 60 participants completed a training form of the Approach-Avoidance Task (AAT) on three consecutive days...

Limited availability of donor organs and risk of ischemia-reperfusion injury (IRI) seriously restrict organ transplantation. Therapeutics that can prevent or reduce IRI could potentially increase the number of transplants by increasing use of borderline organs and decreasing discards. Alpha-1 antitrypsin (AAT) is an acute phase reactant and serine protease inhibitor which limits inflammatory tissue damage. Purified plasma-derived AAT has been well-tolerated in more than 30 years of use to prevent emphysema in AAT deficient individuals...

PURPOSE: Gingival crevicular fluid (GCF) is an important diagnostic source of biomarkers for both periodontitis and gingivitis. However, GCF peptide signature may change depending by factors such as handling and storage. Here we propose a standardized methodology for GCF analysis by MALDI-TOF/TOF-MS in order to distinguish a characteristic peptide signature of gingivitis. EXPERIMENTAL DESIGN: We determined the best storage/handling conditions which may ensure the stability of the endogenous peptidome in GCF and then we performed MALDI-TOF MS comparative analysis...

CRISPR genome editing holds promise in the treatment of genetic diseases that currently lack effective long-term therapies. Patients with Alpha-1 Antitrypsin (AAT) deficiency develop progressive lung disease due to the loss of AAT's antiprotease function and liver disease due to a toxic gain of function of the common mutant allele. However, it remains unknown whether CRISPR-mediated AAT correction in the liver, where AAT is primarily expressed, can correct either or both defects. Here we show that AAV delivery of CRISPR can effectively correct Z-AAT mutation in the liver of a transgenic mouse model...

Abnormalities in alpha-1 antitrypsin (AAT) proteins are risk factors for human disease. While the most common is AAT deficiency, a genetic disorder associated with chronic obstructive pulmonary disease, additional disorders associated with AAT abnormalities are increasingly recognised. We describe a middle-aged woman who presented with fulminant hepatic and multiorgan failure. Evaluation revealed the patient to have a rare AAT phenotype PiEE. Her clinical presentation was consistent with antineutrophilic cytoplasmic antibody-associated vasculitis, and her history suggested features of panniculitis...

Across phylogeny, glutamate (Glu) signaling plays a critical role in regulating neural excitability, thus supporting many complex behaviors. Perturbed synaptic and extrasynaptic Glu homeostasis in the human brain has been implicated in multiple neuropsychiatric and neurodegenerative disorders including Parkinson's disease, where theories suggest that excitotoxic insults may accelerate a naturally occurring process of dopamine (DA) neuron degeneration. In C. elegans, mutation of the glial expressed gene, swip-10, results in Glu-dependent DA neuron hyperexcitation that leads to elevated DA release, triggering DA signaling-dependent motor paralysis...

Disturbances in emotion regulation have been identified as a core feature of patients with a borderline personality disorder (BPD). Findings of studies using experimental measures of emotion processing are mixed, which may be partially explained by the heterogeneity of the BPD population. To address this issue, we investigated differences in experimental measures of emotional action tendencies (approach-avoidance behaviour) and attentional bias to emotional stimuli in BPD subtypes. Data of the Approach-Avoidance Task (AAT) and the Emotional Stroop Task (EST) were collected in 140 BPD patients, previously clustered into four BPD subtypes based on temperament dimensions...

BACKGROUND: Candidemia is one of the most common nosocomial bloodstream infections. Early diagnosis and antifungal treatment improve clinical outcomes in some studies but not all, with diverse data reported from different institutions. Similarly, antifungal resistance is more common in the USA than in Europe, but there is little data regarding the microbiology and clinical course of candidemia in adult patients in Asia. AIMS: (1) To capture species distribution and drug resistance rates among Candida bloodstream isolates, (2) to describe clinical features of candidemia, and (3) to identify factors associated with all-cause mortality, with emphasis on early initiation of antifungal treatment, at a large tertiary University Hospital in China...

BACKGROUND & AIMS: Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder causing pulmonary and liver disease. The PiZ mutation results in mis-folded alpha-1 antitrypsin protein (Z-AAT) leading to hepatocyte accumulation, fibrosis and cirrhosis. RNAi-based therapeutics silencing production of hepatic Z-AAT might benefit patients with AATD-associated liver disease. This study evaluated an RNAi therapeutic to silence production of alpha-1 antitrypsin. METHODS: Part A of this double-blind first-in-human study randomized 54 healthy volunteers (HVs) into single dose cohorts (2 placebo: 4 active), receiving escalating doses of the investigational agent ARC-AAT from 0...

Often few alternative anesthetics for exotic species are available, due to the small numbers of these animals used in research. In this study, we evaluated the depth and duration of anesthesia in Xenopus laevis after their immersion in 3 doses of etomidate (15, 22.5, and 30 mg/L) and in 3 doses of benzocaine (0.1%, 0.5%, and 1%) compared with the 'gold standard,' tricaine methanesulfonate (MS222; 2 g/L). We then chose an optimal dose for each alternative anesthetic according to induction time, duration of surgical plane, and time to complete recovery...
