Inflammatory bowel disease (IBD) includes ulcerative colitis (UC), Crohn's disease (CD) and indeterminate colitis. As these subtypes of IBD display important differences in the behavior of the natural course of the disease, the identification of non-invasive markers for IBD is important. The aim of the present study was to evaluate the serum levels of 10 adipokines and their association with endoscopic activity in IBD. The 10-protein profile (C-peptide, ghrelin, gastric inhibitory polypeptide, glucagon-like peptide-1, glucagon, insulin, leptin, plasminogen activator inhibitor-1, resistin and visfatin) was evaluated using serum from 53 participants (23 UC and 11 CD patients, as well as 19 controls) from Zacatecas (Mexico) by using the Bio-Plex Pro Human Diabetes 10-Plex Panel (Bio-Rad Laboratories, Inc...

Methyl parathion (Me-Pa) is an oxidizing organophosphate (OP) pesticide that generates reactive oxygen species (ROS) through its biotransformation. Some studies have also suggested that OP pesticides have the capacity to alkylate biomolecules, including DNA. In general, DNA methylation in gene promoters represses transcription. NRF2 is a key transcription factor that regulates the expression of antioxidant, metabolic and detoxifying genes through the antioxidant response element (ARE) situated in promoters of regulated genes...

A novel actinobacterium, designated strain NEAU-LZC 7T , was isolated from soil collected from Mount Song and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain NEAU-LZC 7T belonged to the genus Lentzea, with highest sequence similarity to Lentzea violacea JCM 10975T (98.1 %). Morphological and chemotaxonomic characteristics of the strain also supported its assignment to the genus Lentzea. However, DNA-DNA relatedness, physiological and biochemical data showed that strain NEAU-LZC 7T could be distinguished from its closest relative...

In Mexico, due to the high rates of diabetes, overweight, and obesity, there has also been noted an increased newborn weight, which may be contributing to the elevated incidence rate of childhood acute leukemia (AL). We conducted a case-control study in public hospitals of Mexico City aimed to know whether a greater weight at birth is associated with a higher risk of developing leukemia. We included incident cases with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) diagnosed between 2010 and 2015...

Amyloid fibrils, which are closely associated with various neurodegenerative diseases, are the final products in many protein aggregation pathways. The identification of fibrils at low concentration is, therefore, pivotal in disease diagnosis and development of therapeutic strategies. We report a methodology for the specific identification of amyloid fibrils using chiroptical effects in plasmonic nanoparticles. The formation of amyloid fibrils based on α-synuclein was probed using gold nanorods, which showed no apparent interaction with monomeric proteins but effective adsorption onto fibril structures via noncovalent interactions...

The majority of students receiving special education services for emotional disturbance (ED) receive a significant amount of instruction in general education classrooms, which emphasizes curriculums based on college and career readiness standards. In turn, those teachers who provide instruction to students with ED in inclusive settings are responsible for using evidence-based practices (EBPs) for those teaching situations in which they exist to meet free appropriate public education (FAPE) mandates. However, the identification of EBPs is a necessary pre-condition to eventual school adoption and teacher use of such practices...

Mood disorders are a spectrum of neuropsychiatric disorders characterized by changes in the emotional state. In particular, major depressive disorder is expected to have a worldwide prevalence of 20% in 2020, representing a huge socioeconomic burden. Currently used antidepressant drugs have poor efficacy with only 30% of the patients getting in remission after the first-line of treatment. Importantly, mood disorder patients present uncoupling of circadian rhythms. In this regard, melatonin (5-methoxy-N-acetyltryptamine) an indolamine synthesized by the pineal gland during the night, contributes to synchronize body rhythms with the environmental light/dark cycle...

Mitochondrial dysfunction has been described in insulin resistant (IR) states including type 2 diabetes mellitus (T2DM). Previous studies using31 P-MRS in T2DM reported results as relative concentrations of metabolite ratios, which could obscure changes in phosphocreatine [PCr] and [ATP] and attenuate differences between T2DM and NGT individuals. We used a novel image-guided31 P-MRS method to quantitate phosphorus metabolites in vastus lateralis (VL) muscle in 11 T2DM and 14 NGT subjects. Subjects received OGTT, euglycemic insulin clamp,31 P-MRS study to measure absolute concentrations (mM) of [PCr], inorganic phosphate [Pi], and [ATP], and VL muscle biopsy to evaluate mitochondrial density...

BACKGROUND: Rhinitis and conjunctivitis are often linked to asthma development through an allergic pathway. However, runny nose and watery eyes can result from nonallergic mechanisms. These mechanisms can also underlie exercise-induced wheeze (EIW), which has been associated with urgent medical visits for asthma, independent of other indicators of asthma severity or control. OBJECTIVE: To test the hypothesis that rhinitis or watery eyes without cold symptoms (RWWC) in infancy predict development of EIW and urgent respiratory-related medical visits at school age, independent of seroatopy...

Alaria spp. mesocercariae are commonly found in wild boar and other omnivorous mammals. In Europe, the number of cases presenting Alaria mesocercariae infections has been on the rise in the last years. From October to December 2016, samples of muscle from tongue, neck, and mandibular regions were collected from 1 Eurasian badger (Meles meles) and 14 wild boars (Sus scrofa) hunted in the Białowieża Forest, north-eastern Poland. Using the Alaria migration technique (AMT), Alaria mesocercariae were isolated and morphologically identified in one badger and one wild boar...

INTRODUCTION AND AIMS: Malignant dysphagia is difficulty swallowing resulting from esophageal obstruction due to cancer. The goal of palliative treatment is to reduce the dysphagia and improve oral dietary intake. Self-expandable metallic stents are the current treatment of choice, given that they enable the immediate restoration of oral intake. The aim of the present study was to describe the results of using totally covered and partially covered esophageal stents for palliating esophageal cancer...

Oral cancer has become one of the most aggressive types of cancer, killing 140,000 people worldwide every year. Current treatments for oral cancer include surgery and radiation therapies. These procedures can be very effective; however, they can also drastically decrease the quality of life for survivors. New chemotherapeutic treatments are needed to more effectively combat oral cancer. The transmembrane receptor podoplanin (PDPN) has emerged as a functionally relevant oral cancer biomarker and chemotherapeutic target...

G protein-coupled receptors (GPCRs) constitute a large family of receptors that activate intracellular signaling pathways upon detecting specific extracellular ligands. While many aspects of GPCR signaling have been uncovered through decades of studies, some fundamental properties, like its channel capacity-a measure of how much information a given transmission system can reliably transduce-are still debated. Previous studies concluded that GPCRs in individual cells could transmit around one bit of information about the concentration of the ligands, allowing only for a reliable on or off response...

BACKGROUND: The primary components of a diagnostic accuracy study are an index test, the target condition (or disorder), and a reference standard. According to the Standards for Reporting Diagnostic Accuracy statement, the reference standard should be the best method available to independently determine if the results of an index test are correct. Pure-tone thresholds have been used as the "gold standard" for the validation of some tests used in audiology. Many studies, however, have shown a lack of agreement between the audiogram and the patient's perception of hearing ability...
