AIM： To analyze the characteristics of epidemiological, clinical and survival patterns among patients with carcinoma of the stomach. METHODS： We retrospectively studied the characteristics of 186 gastric adenocarcinoma patients at Ahwaz Jundishapur University Hospitals （AJSUH） from September 1, 1996 to September 1, 2002. All the patients had histopathologically-confirmed malignancy. Demographic variables, family history of gastric cancer （GC）, clinicopathologic characteristics and treatment-related variables were analyzed. Univariate analysis was performed with the log-rank test and multivariate analysis with Cox regression. P 〈 0.05 was considered statistically significant. RESULTS： Male to female ratio was 2.6：1. The mean age was 60.6 years and 14% of the patients were younger than 40 years. Adenocarcinoma, gastric lymphoma, and gastric metastasis were found in 94.5%, 2.3%, and 3% patients, respectively. There was an average of 6-mo delay between the initial symptoms and the diagnosis. Among adenocarcinoma groups, intestinal type was the commonest （55.9%） and the distal third was the most common localization （88.4%）. One hundred and thirty-four patients （72.1%） were males. Thirty-one patients （17%） had a family history of GC. Surgery was performed in 90% of patients （non-curative）. CONCLUSION： The epidemiological features of GC in south Iran mimic those in high-risk areas. There is a higher frequency of GC in young patients at our institution. Patients are detected and treated after a relatively long delay. Most patients present in advanced stages, which favors a poor overall survival, Family history of GC has a significant problem in our area, Studying the etiology of this cancer in south Iran and earlier diagnosis and subsequent better cares are recommended.

High sensitive micro resonators are among the best way for measuring the mass of small entities. The principal of these sensors is based on measuring the resonance frequency shift. Putting the entity on the resonator led to change in the resonance frequency of the resonator, but changing the location of entity on the resonator’s surface or changing the temperature can cause undesirable shifts in resonance frequency. To tackle these issues, this paper first introduces a new design for folded springs, these springs attached to a platform for target *** a micro-thermoelectric cooler used to keep the sensor temperature ***3 and SbeTe3 are selected as the n-type and p-type thermoelectric materials respectively. The ceramic interface in thermoelectric coolers is used as a place to putdirectly mass sensors on it.

A Comparison of the Best Place to Fix Endotracheal Tubes for Men and Women When Men and Women Are in the Same Height

引用

Open Journal of Anesthesiology 2014年第7期4卷 153-158页

作者： Shahram Nafisi Mehdi rajabi mohammad Afshar Morteza Rashidian Mitra mohammadzadeh Department of Anesthesiology Advocate Illinois Masonic Medical CenterChicagoILUSA Department of Anesthesia and Critical Care Kashan University of Medical SciencesKashanIran Faculty of Nursing and Midwifery Kashan University of Medical SciencesKashanIran Clinical Innovation Ins Trials Costa MesaCAUSA Shahid Beheshti University of Medical Sciences TehranIran

Background: Comparison of the tracheal tube depth over the same body height of men and women based upon intubation depth markings. Methods: Kashan University of Medical Sciences ethics committee approved the study and written informed consent was taken for each patient. Patients undergoing surgery requiring general anesthesia with oro-tracheal intubation were included in a prospective observational study. After induction of general anesthesia, the endotracheal tube was secured at the point at which the cuff was just below the vocal cord on laryngoscopy. Results: In a statistical study of 682 intubated patients which consisted of 499 women and 183 men, 28 cases of laryngoscopic view grade III and IV were excluded from the study. The measurement markings on the ETT at the level of right corner of the mouth were 20.65 ± 0.13 and 18.52 ± 0.08 for men and women respectively (CI 95%). Patient’s height has a meaningful correlation with the measurement of the fixation point of the ETT. Pearson correlation coefficient between the securing point of the tube and height was 0.2 and 0.357 for men and women respectively. In most cases of men and women of the same height, Mann-Whitney U test rejected the hypothesis that the tube can be fixed in the particular point. Conclusions: In general, men are taller than women. Comparing the fixation depth of the tube, even when man and woman have the same body height, the endotracheal tube might be placed in a deeper level for men rather than women.

Energy Levels of Spin-1/2 Particles with Yukawa Interaction

Journal of Modern Physics 2014年第9期5卷 773-780页

作者： mohammad Reza Shojaei Ali Akbar rajabi Maryam Farrokh Niloufar Zoghi-Foumani Department of Physics Shahrood University of Technology Shahrood Iran

In this article, Yukawa interaction is used to study the relativistic spin-1/2 particles and obtain their energy levels. The role of Yukawa potential on the spin and pseudospin symmetry solution is investigated systematically by solving the Dirac equation with attractive scalar S(r) and repulsive vector V(r) potentials. Bound state spectrum and wave functions of Yukawa potential are obtained. It is found that the energy eigenvalues strongly depend on the potential parameters.

Leptin Receptor in Ram Epididymal Spermatozoa

引用

Engineering（科研） 2012年第10期4卷 121-123页

作者： mohammad Roostaei-Ali Mehr Reza rajabi-Toustani Rasool Motamedi-Mojdehi Department of Animal Science Faculty of Agricultural Sciences University of Guilan Rasht Iran

This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then they were purified. Specific bands (98 and 308 bp) for Ob-R and Ob-Rb were detected after RT-PCR in both epididymal spermatozoa and placental cotyledon. We may conclude that Ob-R and Ob-Rb mRNA are present in ram epididymal spermatozoa and leptin perhaps exerts physiological effects, as already demonstrated in human.

<i>GJB2</i>Gene Related Nonsyndromic Hearing Loss in Mazandaran Province, North of Iran

引用

Open Journal of Genetics 2020年第3期10卷 51-63页

作者： Elaheh Hosseini Seyed Saeid Mousavi Atefeh Khoshaein Fatemeh Daneshpour Moosa rajabi Vandchali S. mohammad Bagher Hashemi-Soteh Novin Genetic Diagnostic Laboratory Sari Iran Mehregan Genetic Counseling Center Sari Iran Novin Genetic Counseling Center Sari Iran Genetic Counseling Center State Welfare Organization of Mazandaran Province Sari Iran Immunogenetic Research Center Molecular and Cell Biology Research Center Faculty of Medicine Mazandaran University of Medical Sciences Sari Iran

Introduction: Congenital hearing loss is the most common sensory deficit in the world and mutations in GJB2 gene are the most common cause of deafness in many populations. Frequency of GJB2 mutations is estimated about 16% in Iran and varies among different provinces with a decreasing trend from north to south. The aim of this study was to investigate the frequency of GJB2 mutations in Mazandaran province, north of Iran, among non-syndromic hearing loss patients. Methods: 262 patients from 204 families participated in this study. After genomic DNA extraction, GJB2 gene analysis was carried out using DNA sequencing of both coding and non-coding regions by ABI 3130XL genetic analyzer. Results: 30.15% of all subjects showed mutations in GJB2 gene. Four mutations, including c.35delG (Gly12Valfs*), IVSI-1 + 1G > A, c.95G > A (Arg32His) and c.224 G > A (Arg75Gln) comprises 69.89% of all mutations in this study c.35delG and IVSI-1 were the most common mutations among patients respectively. Codon 75 mutation (c.224G > A. p: Arg75Gln) with autosomal dominant inheritance was seen in 7 cases from 3 families. 22 patients showed only one mutation in GJB2 gene and in 126 (48.09%) individuals, parents had a consanguineous marriage. Discussion: Frequency of GJB2 gene related hearing loss among patients was higher than average (16%) in this province. This study also showed a dominant inheritance pattern of GJB2 gene in this area. Consanguineous marriage also showed highly frequent among parents. More investigation needs to clarify cause of hearing loss in those 22 patients with one mutation in GJB2 gene, either two gene inheritance or another gene may be responsible for hearing loss.
