Background And Aim: The treat-to-target strategy has emerged in ulcerative colitis management. Mucosal healing is the best target, albeit not in induction therapy of acute diseases as clinical conditions vary over a short duration. To determine the targets during induction therapy for acute ulcerative colitis, we identified markers to predict mucosal healing at 3 and 12 months of initiating the induction therapy. Read More

Objective: To assess effects of neonatal transport on transient tachypnea of the newborn (TTN) in outborn term neonates.
Study Design: This retrospective cohort study included 66 term neonates diagnosed with TTN and transported to the Osaka Women's and Children's Hospital neonatal intensive care unit between January 2003 and March 2018. A multivariate logistic regression analysis identified perinatal and neonatal transport factors associated with adverse short-term outcomes defined as mechanical ventilation >48 hours, continuous positive airway pressure >72 hours, pulmonary hemorrhage, and requirement for inhaled nitric oxide, thoracentesis, or surfactant replacement therapy.

Purpose: To test the hypothesis that mitochondrial respiration contributes to local changes in hydration involved in phototransduction-driven expansion of outer retina, as measured by structural responses on optical coherence tomography (OCT) and diffusion magnetic resonance imaging (MRI).
Methods: Oxygen consumption rate and mitochondrial reserve capacity of freshly isolated C57BL/6 and 129S6/SvEvTac mouse retina were measured using a Seahorse Extracellular Flux Analyzer. Light-stimulated outer retina layer water content was determined by proton density MRI, structure and thickness by ultrahigh-resolution OCT, and water mobility by diffusion MRI. Read More

During placental development, mononuclear cytotrophoblasts differentiate and fuse to syncytiotrophoblasts (STB) to form syncytia, which secrete human chorionic gonadotropin (hCG). Decreased maternal perfusion of the placenta, which leads to placental dysfunction, induces changes in trophoblast syncytialization. Our previous study showed that calreticulin (CRT), a Ca2+-binding molecular chaperone found in the endoplasmic reticulum, is expressed in the human placenta and is involved in regulating extravillous trophoblast invasion, although its role in villous trophoblasts remains unclear.

Study Question: Is ageing associated with a decline in semen quality and molecular changes to human sperm?
Summary Answer: Semen quality declines with advancing age and characteristic molecular changes take place during the ageing process, including increased sperm DNA damage, altered sperm protamination and altered seminal plasma miRNA profile.
What Is Known Already: During ageing, the reproductive system is exposed to physiological changes and potentially damaging factors that may impair testicular function. Reactive oxygen species (ROS) can induce errors during DNA replication, transcription or post-transcriptional events (fragmentation, chromatin condensation abnormalities and protamine expression defects).

To better understand uterine inflammation in postpartum dairy cows we collected sequential cytobrush samples at 29-35 and at 49-55 d in milk (DIM). Based on the uterine cytology, cows were classified as Non-endometritic (n = 23; <18% neutrophils) or Endometritic (n = 12; ≥18% neutrophils) at 29-35 DIM and Non-endometritic (n = 17; <10% neutrophils) or Endometritic (n = 9; ≥10% neutrophils) at 49-55 DIM. Cows defined as Sham Controls (n = 6) were examined by vaginoscopy at 29-35 DIM and identified as Non-endometritic (<10% neutrophils) at 49-55 DIM. Read More

Background: Constitutive (agonist-independent) activity is a prerogative of many G protein-coupled receptors (GPCRs) including α-adrenoceptors (α-ARs). Inhibition of such an activity at α-AR subtypes by antagonists with negative efficacy is difficult to be adequately tested.
Methods: In the present experimental approach, we compared the activity of three calcium channel blockers (nifedipine, diltiazem and verapamil) and of three potent benzodioxane-based α-AR antagonists, differing for subtype selectivity and inverse agonist properties, in producing smooth muscle relaxation and negative inotropy under the same test conditions.

The aim of this study was to evaluate whether rupture on blood-brain barrier (BBB) can be a pathway for trichlorfon-induced neurotoxic effects, and to investigate its implications on oxidative status, cell viability and brain neurotransmitters in silver catfish (Rhamdia quelen). The BBB permeability was increased in fish exposed for 24 h to 22 mg/L of trichlorfon compared to the control group, as well as in those exposed to 11 and 22 mg/L of trichlorfon for 48 h. Compared to the control group, brain reactive oxygen species and lipid peroxide levels were higher when exposed to 22 mg/L of trichlorfon and 11 and 22 mg/L of trichlorfon after 24 h and 48 h, respectively, while the antioxidant capacity against peroxyl radical levels was lower.

Study Objective: The Androgen Receptor (AR) harbors a variable repeat of a variable number of glutamine residues [(CAG)n] which seems to affect inversely AR transcriptional activity. We assessed whether (CAG)n affect the sequence of the androgen-sensitive pubertal events and body composition in prepubertal girls.
Design: and participants: Nested case-control study within the Growth and Obesity Cohort Study of 1196 low-middle income children (≈50% girls) from Santiago, Chile. Read More

This paper proposes a model of West Nile Virus (WNV) including threshold control policies concerning the culling of mosquitoes and birds under different conditions. Two thresholds are introduced to estimate whether and which control strategy should be implemented. For each mosquito threshold level [Formula: see text] the dynamical behaviour of the proposed non-smooth system is investigated as the bird threshold level [Formula: see text] varies, focusing on the existence of sliding domains, the existence of pseudo-equilibria, real or virtual of the endemic equilibria, global stability of these steady states, and the most interesting case of the occurrence of a novel globally asymptotically stable pseudo-attractor.
