introduction: the aim of this study was to evaluate the effects of aerobic exercise on brain natriuretic peptide (bnp) and c-reactive protein (crp) levels in women with cardiovascular diseases. materials and methods: in this semi experimental study, thirty female patients with at least one coronary artery stenosis (more than70%) were chosen and divided into two groups of aerobic training (n=15)...

melanocortin- 4 receptor (mc4r) and agouti- related peptide (agrp) are involved in energy homeostasis in rats. according to mc4r and agrp effects on luteinizing hormone (lh) secretion, they may influence the estrous cycle of rats. therefore, the aim of this study was to investigate the expression of mc4r and agrp mrnas at different stages of estrous cycle in the rat’s hypothalamus. the estrous ...

introduction: ubiquicidin (ubi) 29-41 is a synthetic antimicrobial peptide that binds with the microbial cell membrane at the location of infection. this study was conducted to evaluate its probable efficacy as an infection-imaging agent with potential to differentiate bacterial infection from sterile inflammation in humans. methods: fifteen diabetic foot patients (10 males and 5 females) with...

background: ubi 29-41 (a derivative of antimicrobial peptide ubiquicidin) labelled with 99mtc is reported to discriminate between bacterial infections and sterile inflammatory processes. in this study, three lyophilized kit were performed, one of them based on the direct labelling with only sncl2 as reducing agent , and other two based on 6- hydrazinopyridine-3-carboxylic acid (hynic) and trici...

Background: Defensin peptide isolated from plants are often heterogeneous in length, sequence and structure, but they are mostly small, cationic and amphipathic. Plant defensins exhibit broad-spectrum antibacterial and antifungal activities against Gram-positive and Gram-negative bacteria, fungi and etc. Plant defensins also play an important role in innate immunity, such as he...

Despite the great advances in solid-phase peptide synthesis (SPPS), incorporation of certain functional groups into sequences is restricted by compatibility building blocks with conditions used during SPPS. In particular, introduction highly reactive modern bioorthogonal reactions peptides remains elusive. Here, we present an optimized synthetic protocol enabling installation two strained dieno...

Polyetheretherketone (PEEK) has favorable biomechanical properties to be used as an implant material. Unfortunately, it is hydrophobic and does not promote cellular adhesion, which could result in poor integration with bone tissue. Bio-functionalization of PEEK surface osteogenic peptides derived from extracellular matrix proteins excit-ing approach encourage formation around the implant. In cu...

introduction: it has been shown that some primary human tumors and their metastases, including prostate and breast tumors, over-express gastrin-releasing peptide (grp) receptors. bombesin is a neuropeptide with a high affinity for these grp receptors. the purpose of this study was to prepare and evaluate the characteristics of a new freeze-dried kit, [6-hydrazinopyridine-3-carboxylic acid (hyni...

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...

we have employed a peptide-based antibody generation protocol for producing antibody against human nestin. using a 12-mer synthetic peptide from repetitive region of human nestin protein devoid of any n- or o-glyco-sylation sequences, we generated a mouse monoclonal antibody capable of recognizing human, mouse, bovine, and rat nestin. a wide variety of nestin proteins ranging from 140-250 kda w...
