Heligmosomoides polygyrus is a widely used gastrointestinal helminth model of long-term chronic infection in mice, which has not been well-characterized at the antigenic level. We now identify the major targets of the murine primary Ab response as a subset of the secreted products in H. polygyrus excretory-secretory (HES) Ag. An immunodominant epitope is an O-linked glycan (named glycan A) carr...

Abstract Sacubitril/valsartan (SAC/VAL), an angiotensin receptor blocker-neprilysin inhibitor, has been widely used to treat several types of heart failure. Nevertheless, the effects drugs in mitral regurgitation patients, from molecular level therapeutic effects, remain unclear. This study investigates roles SAC/VAL on cardiac function, mitochondrial quality, autophagy, mitophagy, and natriure...

traumatic brain injury (tbi) is one of the serious neurodisorders commonly caused by car accidents and sports. preventive measures are highly recommended to reduce the risk and number of tbi cases. after tbi, the primary injury to the brain initiates a secondary injury process that spreads via multiple molecular mechanisms in the pathogenesis of tbi. many studies in animals using cdna microarra...

Introduction: The coagulation factor 13 has a fundamental role in homeostasis, protective effects on thrombosis, and some other associated diseases. Due to increasing the chronic coagulability of major thalassemic patients, this study was conducted with aim determining the prevalence of Val34LeuFXIII polymorphism in the thalassemic patients. Materials and methods: The present case-control stud...

OBJECTIVE To examine the analgesic and opioid-sparing effects of parecoxib following major gynecologic surgery. METHODS This is a large subset analysis of patients from a multicenter, randomized, double-blind, placebo-controlled study of parecoxib/valdecoxib (PAR/VAL) for postoperative pain. Pain severity, pain interference with function, opioid use, occurrence of opioid-related symptoms, and...

The design of the synthetic 19-residue peptide Boc-Leu-Aib-Val-Ala-Leu5-Aib-Val-D-Ala-d-Leu-Leu10-Val-Phe-Val-Aib-D-Val15-Leu-Phe-Val-Val-OMe (Aib, alpha-aminoisobutyric acid; OMe, methyl ester) was intended to produce a crystalline peptide with independent helical and hairpin domains. The design was partially based on an octapeptide with the same sequence as residues 11-18 above, which was sho...

Amino acid sequences of three canine bombesin-like peptides were determined after sequential purification of an extract obtained from 820 g of intestinal muscle. These three peptides contained 27, 23, and 10 amino acid residues. The sequences of the two shorter forms were identical to the corresponding carboxyl-terminal sequence of the heptacosapeptide. The sequence of the largest peptide is H2...

Escherichia coli tRNA(Val) with pyrimidine substitutions for the universally conserved 3'-terminal adenine can be readily aminoacylated. It cannot, however, transfer valine into polypeptides. Conversely, despite being a poor substrate for valyl-tRNA synthetase, tRNA(Val) with a 3'-terminal guanine is active in in vitro polypeptide synthesis. To better understand the function of the 3'-CCA seque...

Since Phe-tRNA synthetase of Neurospora crassa reacts with tRNAV”’ of Escherichia coli to produce Phe-tRNAV&‘, the parameters that effect the reverse reaction were examined. Similarly, the interaction of Val-tRNA synthetase (E. coti) with Phe-tRNAVal and Val-tRNAVal (E. coli) was studied. Phe-tRNA synthetase (N. crassa) can catalyze the deacylation of both Phe-tRNAVa 1 (E. coli) and Val-tRNAV”’...

The peptide Boc-Val-Val-Aib-Pro-Val-Val-Val-OMe has been synthesized to investigate the effect of introduction of a strong beta-turn promoting guest segment into an oligopeptide with a tendency to form extended structures. 1H-nmr studies in solution using analysis of NH group solvent accessibility and nuclear Overhauser effects suggest an appreciable solvent dependence of conformations. In chlo...
