This study evaluates low protein diets with amino acid supplement on growth, biochemical markers and muscle acids profile in broilers under high ambient temperature. A total of 480 one-day-old chicks were allocated into three treatments four replicates (n = 40). Control fed optimal which contains 23% 21% crude (CP) 65% methionine + cysteine/ lysine (Met Cys/Lys) 55% threonine/lysine (Thr/Lys), ...

In addition to dose-response studies, modeling of N utilization, depending on intake of the first limiting amino acid in the diet, is one of the tools for assessing amino acid requirements in growing animals. Based on a verified nonlinear N-utilization model and following the principles of the diet dilution technique, N-balance experiments were conducted to estimate the Thr requirement of fast-...

This experiment was carried out to evaluate the effects of four levels of dietary threonine (Thr) supplementations on growth performance, gut size and histomorphometric alterations of small intestines in broiler chicks in 1-14 days. Two hundred eighty-eight Ross 308 one-day-old male broiler chicks were randomly assigned to four treatments with six replicates (12 birds per replication) received ...

The logistic sigmoid function curve provides an accurate description of the baroreflex input-output relationship and is the most commonly used equation for this purpose. The threshold (Thr) and saturation (Sat) values for the baroreflex are commonly defined as the values of mean arterial pressure (MAP) at which the reflexly controlled variable (e.g., heart rate or sympathetic nerve activity) is...

We previously demonstrated that ERK/PKC signaling pathways play a key role in regulation of Ca(2+) sensitivity and contractility of the uterine artery. The present study tested the hypothesis that ERK and PKC differentially regulated myosin light chain phosphatase activity by phosphorylation of myosin phosphatase target protein-1 (MYPT-1) and CPI-17. Agonist-induced contractions and phosphoryla...

Background and purpose - There have been few studies on the effect of THR on pregnancy or delivery, and they have mainly been based on small and regional data. We evaluated the birth rate nationwide in patients of fertile age with THR. Patients and methods - This nationwide population-based cohort study was based on registry data on 5,863 Finnish THR patients who had undergone a THR between 198...

First published March 4, 2009; doi:10.1152/ajpcell.00343.2008.—Peroxisome proliferator-activated receptor (PPAR)ligands, thiazolidinediones, have been demonstrated to regulate vascular reactivity. We examined the effect of p...

Replication of tobacco mosaic virus (TMV) is connected with endoplasmic reticulum (ER)-associated membranes at early stages of infection. This study reports that TMV movement protein (MP)-specific protein kinases (PKs) associated with the ER of tobacco were capable of phosphorylating Thr(104) in TMV MP. The MP-specific PKs with apparent molecular masses of about 45-50 kDa and 38 kDa were reveal...

Implant surface topography is a key factor in achieving osseointegration. l-Threonine can be chemically and stably bonded to titanium surfaces by phosphorylation. This study investigated the degree of in vivo osseointegration of an implant with a novel o-phospho-l-threonine (p-Thr)-binding surface. MC3T3-E1 cells were seeded on the p-Thr binding surface and machined surface disks, and initial c...
