The aim of this study is the synoptic analysis of the atmospheric conditions concurrent with the heavy precipitations of Lorestan, Fars and Hormozgan provinces and determination of the temporal and spatial distribution of them. Requested atmospheric data for this research was taken from databases related to the National Organization of Atmosphere and Oceanology of United States. More maps of the site were taken. Then the earth surface, 500,700 and 850 Hecto Pascal maps, orbital and meridional winds, earth temperature of earth surface and top of the atmosphere were prepared in Grads software and some of maps were drawn in GIS software. The following results were obtained: On the earth surface map, the main controller role is with the Siberian high-pressure, the Azores’s dynamic high-pressure and integrated mode of the Sudan and the Mediterranean low-pressure systems. The main controller role in high levels is with the high altitude center of Azores in the back of the system, the high altitude center of Arabia in the front of the system and deep traffic of North Africa. Another important factor is the moisture mixture of Mediterranean Sea, Red Sea, Persian Gulf, Oman Sea and Indian Ocean. Air rise factor with enhancing meridional winds that causes subsidence of cold air, rising warm air and strengthening the polar front is one of the heavy rainfall conditions too. Eastern winds cause entering of moisture from the Indian Ocean and western winds cause strengthening of cyclones and heavy rainfall in the region.

Gonadotropin and Testosterone hormone’s serum levels and partial deletions in the AZFc region in Iranian oligozoospermia infertile males

Health 2011年第9期3卷 566-570页

作者： Nasser Salsabili Reza Mirfakhraei Maryam Montazeri Mitra ataei Paricheher Yaghmaei Gholamreza Pourmand 不详

To investigate the relation of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and Testosterone serum levels with partial deletions in the AZFc region in Iranian oligozoospermia males. Material and methods: thirty infertile oligozoospermia and 52 Iranian fertile men included. The hormonal assays were measured by the Radioimmunoassay (RIA). Multiplex polymerase chain reaction (M-PCR) using eight sequence-tagged site (STS) markers were measured on the Yq11 chromosome. Results: The mean of FSH and LH levels in all oligozoospermia males were higher than fertile men (p < 0.001) and testosterone was lower significantly (p < 0.001). Five patients showed partial deletions in AZFc region (four had gr/gr and one had b2/b3 deletions). Six fertile men showed partial deletions (five gr/gr and one b2/b3) with higher level of FSH, LH in their group (p < 0.05). Conclusion: According to high incidence of partial deletions in the AZFc region among Iranian oligozoospermia males, hormonal assay and molecular screening should be advised before considering for ART treatments.

Hantavirus is a zoonosis transmitted from rodents to humans. Asymptomatic infected rodents can secrete hantaviruses in the urine, feces, and saliva. The main route of infection transmission to human is aerosols contaminated with the virus. This study was designed to evaluate the serological and molecular prevalence of hantavirus as an emerging zoonoses disease among street sweepers in Isfahan province, central Iran. Serum samples from 200 street sweepers in healthy condition and those with recent renal failure were tested by ELISA (IgM and IgG). Molecular analysis was subsequently applied for IgM positive cases. From these samples, 9 (4.5%) were positive, of which 2 (22.22%) were positive for both IgM and RT-PCR, while 7 (77.77%) were positive for IgG. The mean age and work experience of the positive cases were 39.7 and 11.5 respectively. According to our observations, all positive cases reported prevalence of rodents in their work place. The logistic regression test showed that the age and work experience were not risk factors for being positive, but prevalence of rodents in work place was a risk factor for being positive, when compared with negative cases. This is the first comprehensive study on the prevalence of hantavirus with positive results coming from Iranian population, which can raise the public awareness for the hantavirus infections as a public health threat.

文章对金刚石绳锯的生产效率进行了预测研究,测量了伊朗13个采石场中金刚石绳锯切割碳酸盐石材的性能。从这些采石场的石材荒料中分别选取石材样品用于实验室测试,测定其中石英含量及单轴抗压强度(UCS),发现生产率与对应的石英含量和单轴抗压强度相关。运用多元与单元回归分析评价锯切效率与石材性能的相互关系,通过统计测试验证开发的模型,研究认为运用该模型可有效预测金刚石绳锯切割碳酸盐石材的锯切效率。
