OBJECTIVES: We aimed to investigate prognostic effects of plasma levels of ghrelin before and after gastrectomy in gastric cancer (GC). METHODS: We followed 81 GC patients up to 3 years in this study. They were candidates for curative gastrectomy with or without neoadjuvant chemotherapy. Plasma levels of total and active ghrelins before and after the operation were assessed. Association of plasma levels of ghrelin with survival were assessed and adjusted for other potential prognostic factors using Cox regression analyses...

Acinetobacter baumannii is a major opportunistic pathogen in healthcare settings worldwide. In Iran, there are only few reports on the prevalence of aminoglycoside resistance genes among A. baumannii isolates. The aim of this study was to investigate the existence of aminoglycoside-modifying enzyme (AME) genes from A. baumannii strains collected at a university teaching hospital in Iran. One hundred A. baumannii strains were collected between 2014 and 2015 from hospitalized patients at Loghman Hakim Hospital, Tehran, Iran...

BACKGROUND: Salmonella enterica serovar Typhimurium (S. Typhimurium) causes gastroenteritis in humans and paratyphoid disease in some animals. Given the emergence of antibiotic resistance, vaccines are more effective than chemotherapy in disease control. OBJECTIVES: The aim of this experimental study was to evaluate the immunogenicity of diphtheria toxoid (DT) conjugated with S. Typhimurium -derived OPS (O side chain isolation) in mice to determine its potential as a vaccine candidate against salmonellosis...

BACKGROUND: Endometriosis is a commonly-encountered gynecological disease characterized by the presence of endometrial glandular and stromal cells outside of the uterus. Several studies have been conducted on endometriosis, however its molecular mechanism and pathogenesis are still not completely clear. The role of ELAM-1 gene in mediating the adhesion of tumor cells to endothelial cells by binding to ELAM-1 ligands expressed by eosinophils, neutrophils, monocytes, natural killer cell effectors, T lymphocyte cells, and cancer (progenitor/stem) cells is well studied...

BACKGROUND: Hormone therapy is currently the mainstay in the management of locally advanced and metastatic prostate cancer. We performed a systematic review to compare safety, efficacy and effectiveness of degarelix, a new gonadotropin-releasing hormone (GnRH) antagonist (blocker), versus gonadotropin-releasing hormone (GnRH) agonists. METHODS: MEDLINE, Web of Science and the Cochrane library were searched to identify all of the published Randomized Controlled Trials (RCTs) that used degarelix versus gonadotropin-releasing hormone agonists with or without anti-androgen therapy for the treatment of prostate cancer...

Physical inactivity is a major health problem in developing countries. Regular Physical Activity (RPA) can reduce the risk of many diseases such as cardiovascular disease, diabetes, and obesity that are prevalent in middle and old ages specifically in women. The (RPA) status among middle-aged Iranian women is not well known. The purpose of this study was to investigate the physical activity status and related factors among middle-aged women in Hamadan, a city in western Iran. The participants of this cross-sectional study were comprised of 866 middle-aged women in Hamadan who were selected using a proportional stratified random sampling method in 2015...

BACKGROUND: Kindler syndrome (KS) is an autosomal recessive skin disease characterized by actual blistering, photosensitivity and a progressive poikiloderma. The disorder results from rare mutations in the KIND1 gene. This gene contains 15 exons and expresses two kindlin-1 isoforms. OBJECTIVE: The aim of this investigation was to analyze mutations in the exons 1 to 15 of KIND1 gene in an Iranian family clinically affected with Kindler syndrome. METHODS: The mutations analysis of 15 coding exons of KIND1 gene was performed with PCR-SSCP and direct sequencing in 14 subjects from one Iranian family clinically affected with Kindler syndrome...

BACKGROUND: Cholecystectomy is considered as the most important and relatively common postoperative pain control often begins in recovery room by using systemic narcotics that may have some side effects. The aim of this study is to evaluate the effect of premedication with oral tizanidine on pain relief after elective laparoscopic cholecystectomy. MATERIALS AND METHODS: In this double-blinded clinical trial, 70 adults of American Society of Anesthesiologist physiologic state 1 and 2 scheduled for elective laparoscopic cholecystectomy under general anesthesia were studied and randomly divided in two study and control groups...

INTRODUCTION: Plasma adiponectin level is markedly in-creased among patients on hemodialysis. This investigation aimed to evaluate the relationship between renin-angiotensin system blockade and serum adiponectin concentration in nondiabetic patients on hemodialysis. MATERIALS AND METHODS: This randomized double-blind controlled trial was conducted on a group of nondiabetic patients on regular hemodialysis. The first group received losartan, 12.5 mg twice per day for the 1st week, 25 mg twice per day during the 2nd week, and 75 mg/d from the 3rd week to the end of the 16th week...

The aim of this study was to develop nanofibrous gelatin substrates for eyelid fat stem cell (EFSC) expansion that can serve as a potential alternative substrate to replace human amniotic membrane. Biocompatibility results indicated that all substrates were highly biocompatible, as EFSCs could favorably attach and proliferate on the nanofibrous surfaces. Microscopic figures showed that the EFSC were firmly anchored to the substrates and were able to retain a normal stem cell phenotype. Immunocytochemistry (ICC) and real time-PCR results revealed change in the expression profile of EFSCs grown on nanofibrous substrates when compared to those grown on control in epithelial induction condition...

The effective treatments of endotoxemia are necessary to prevent high mortality rates. Hence, the present study was performed to clarify the antiendotoxic effects of tyloxapol and pentoxifylline in experimentally induced endotoxemia in sheep. Thirty clinically healthy 1-year-old Iranian fat-tailed ewes were randomly divided into six equal experimental (n = 5) groups, comprising Negative and Positive control, Tyloxapol 1, Tyloxapol 2, Pentoxifylline 1 and Pentoxifylline 2. Phenol extracted lipopolysaccharide from Escherichia coli serotype O55:B5 was infused at 2 µg/kg intravenously...

The aim of this study was to develop nanofibrous silk substrates for limbal stem cell expansion that can serve as a potential alternative substrate to replace human amniotic membrane. The human limbal stem cell was used to evaluate the biocompatibility of substrates (random and oriented nanofibrous mats, and human amniotic membrane) based on their phenotypic profile, viability, proliferation, and attachment ability. Biocompatibility results indicated that all substrates were highly biocompatible, as limbal stem cells could favorably attach and proliferate on the nanofibrous surfaces...

Unrestricted somatic stem cells (USSCs) loaded in nanofibrous polycaprolactone (PCL) scaffolds can be used for skin regeneration when grafted onto full-thickness skin defects of rats. Nanofibrous PCL scaffolds were designed by the electrospinning method and crosslinked with laminin protein. Afterwards, the scaffolds were evaluated by scanning electron microscopy, and physical and mechanical assays. In this study, nanofibrous PCL scaffolds loaded with USSCs were grafted onto the skin defects. The wounds were subsequently investigated 21 days after grafting...

Many bacterial pathogens use quorum-sensing (QS) signaling to regulate the expression of factors contributing to virulence and persistence. Bacteria produce signals of different chemical classes. The signal molecule, known as diffusible signal factor (DSF), is a cis-unsaturated fatty acid that was first described in the plant pathogen Xanthomonas campestris. Previous works have shown that human pathogen, Pseudomonas aeruginosa, also synthesizes a structurally related molecule, characterized as cis-2-decenoic acid (C10: Δ(2), CDA) that induces biofilm dispersal by multiple types of bacteria...
