Background: To describe the baseline characteristics of patients with heart failure and preserved left ventricular ejection fraction enrolled in PARAGON-HF trial (Prospective Comparison Angiotensin Receptor Neprilysin Inhibitor With Blocker Global Outcomes HFpEF) comparing sacubitril/valsartan to valsartan reducing morbidity mortality. Methods Results: We report key demographic, clinical, laboratory findings, therapies, 4822 randomized PARAGON-HF, grouped by factors that influence criteria...
An expansion of fat mass is an integral feature patients with heart failure and preserved ejection fraction (HFpEF). While body index (BMI) the most common anthropometric measure, a measure central adiposity-the waist-to-height ratio (WHtR)-focuses on content distribution; not distorted by bone or muscle mass, sex, ethnicity; may be particularly relevant in HFpEF. The PARAGON-HF trial randomized 4796 ≥45% to valsartan sacubitril/valsartan. current work characterizes association BMI WHtR...
We have applied a statistical protocol based on principal component analysis, clustering methods, and discriminant analysis for the identification of sperm subpopulations in computer-assisted (CASA) data. Samples were obtained from cauda epididymis 11 Iberian red deer cryopreserved following standard protocol. Motility by CASA was analyzed just after recovery, before freezing, thawing, eight motility descriptors each individual spermatozoon recorded. Sperm viability acrosomal status also...
Antioxidants could improve sperm media, extending the viability of spermatozoa and protecting their DNA. The protective ability lipoic acid, melatonin, Trolox crocin was tested on red deer incubated at 37°C. Cryopreserved were thawed with 1 mM or 0.1 each antioxidant, without oxidative stress (100 μM Fe2+). Motility (CASA), viability, mitochondrial membrane potential acrosomal status assessed. Lipoperoxidation (malondialdehyde production), intracellular reactive oxygen species (ROS) DNA...
ABSTRACT: The main goal of this study was to investigate the potential protective effects enzymatic and nonenzymatic antioxidants on cryopreservation injuries red deer epididymal spermatozoa. In Experiment 1, sperm freezability catalase, superoxide dismutase, a combination thereof were studied. 2, cryoresistance evaluated when different antioxidants, such as vitamin E, C, butylated hydroxytoluene (BHT), added freezing extender. Sperm quality judged in vitro by microscopic assessments...
Fe 2 + /ascorbate, hydrogen peroxide (H O ), and hypoxanthine/xanthine oxidase (XOD) are commonly used for inducing oxidative stress on spermatozoa. A comparative study of these agents was carried out thawed spermatozoa from red deer. First, we tested a high, medium, low concentration each agent: 100, 10, 1 μM (hydroxyl radical generator); mM, 10 H ; mU/ml XOD (superoxide generator), incubated at 37 °C 180 min. Intracellular reactive oxygen species (ROS; DCFDA) increased with dose time...
In the present study, we have related mitochondrial membrane potential (DeltaPsim) and forward scatter (FSC) to apoptotic-related changes in spermatozoa. Thawed red deer spermatozoa were incubated synthetic oviductal fluid medium (37 degrees C, 5% CO2), with or without antioxidant (100 microm Trolox). At 0, 3, 6 9 h, aliquots assessed for motility stained a combination of Hoechst 33342, propidium ioide (PI), YO-PRO-1 Mitotracker Deep Red flow cytometry. The proportion YO-PRO-1+ PI+...
This study was conducted to compare the effects of thermal stress on growth performance and some immunity variables broiler chickens. Birds were randomly assigned one three treatments as follows: cold (CS, 12±1°C), (b) heat (HS, 33±3 °C) (c) thermoneutral (TN, 24±2 °C). Body weight gain (BWG), feed intake (FI), water (WI) conversion ratio (FCR) recorded. In order evaluate primary secondary humoral immune responses, two birds per replicate intravenously administrated with a suspension 7%...
The seminal work of Mills et al. (1993) lists 137 established aquatic species as nonindigenous to the Great Lakes (two plants are further subdivided into two subspecies groups). We have removed seven these species: three been redefined probably native, and four (including both Sonchus arvensis) reclassified terrestrial. Thirty-five that arrived prior 1993 (some due reclassification, some a time lag in discovery reporting) added list. Twenty-four new become post-1993, bringing total 188 (with...
