Abstract
Alfalfa (Medicago sativa) is a plant with phytoestrogenic properties, which has been used as a major part of diets in husbandry. Since there are controversial reports related to the effects of alfalfa consumption on animal fertility, its effects on rat testicular tissue were assessed in the present study. Control (n=15) and alfalfa (n=15) groups were fed with ordinary rat chow and ordinary rat chow plus alfalfa, respectively. Testicles were removed after 30, 45, and 60 days of consumption, and tissue sections were prepared to assess histomorphometric changes related to alfalfa consumption.
Based on the results, there was no significant difference in length, width, and volume of testes of treated rats to control in all groups. But the number of testicular spermatogonia cells, primary spermatocyte cells, primary spermatid cells, testicular spermatozoid cells and Leydig cells significantly or insignificantly increased in rats that received alfalfa for 30 days but all of these parameters insignificantly decreased in rats that received alfalfa for 60 days. The cause of these changes may be due to estrogenic or anti-estrogenic, antioxidant and endocrine effects of alfalfa.
Conclusion: Consumption of alfalfa for short time had only a transient positive effects on testicular tissues but use of alfalfa for 60 days had little destructive effects on testicular tissue in rats. So longer durations of time could be suggested for further research on the effects of alfalfa on rat’s reproduction index.

Abstract
BACKGROUND It is important to examine scale and scope of the reproductive health among socially-vulnerable women. The study was aimed at testing the hypothesis that as compared to general population, reproductive health is poorer among socially-vulnerable women. METHODS We enrolled 100 cases and 203 controls conducted from January 2010 to January 2011. Cases were socially-vulnerable women seeking care from Tehran's Center for Improving Social Health of Socially-Damaged Women (Specific Center for Socially-Vulnerable Women). Controls were women referring to health centers of Tehran. RESULTS Mean age of cases and controls were 34.1 years and 33.8 years, respectively. Unwanted pregnancy was reported by 62.9% of cases and 33% of controls. Among socially-vulnerable women, 50.6% of abortions were reported to happen during the period in which they were using drugs. Among cases, 45.7% reported to give birth to low birth weight newborns and for controls was 11.7%. Among cases with low birth weight child, 64.9% used drug during pregnancy. Birth control was reported by 81.5% of cases and 92.8% controls. The most common method of contraception was condom among both cases (66%) and controls (31.2%). At least one screening test for cervical cancer was reported by 82.8% of controls and for 47% of cases. Mean age at first sexual intercourse was 15.7 years among cases and 20.9 years among controls. Mean Sexual Performance Scale score was lower among cases (22.3) than controls (25.9) and sexual dysfunction was more prevalent among cases (80.6%) than controls (59.1%). CONCLUSION A high prevalence of reproductive health disorders was documented among socially-damaged women as compared to the women from general population.

Abstract
BACKGROUND Epidemiologic and molecular evidences have established a strong link between high risk types of Human Papilloma Virus and a subgroup of Head and Neck Squamous Cell Carcinomas (HNSCC). We evaluated the frequency of HPV positivity in HNSCC and its relationship to demographic and some risk factor variables in an open case- control study. METHODS Fourteen recently diagnosed patients with squamous cell cancer of oropharynx, hypopharynx and larynx aged 18-50 years were examined from 2008-2010 in Tabriz, Iran. HPV DNA was extracted from paraffin-embedded blocks of each patient's sample for PCR evaluation. Saliva samples of 94 control cancer-free subjects were collected for DNA analysis. Multivariable logistic regression method was used to calculate odds ratio for case-control comparisons. RESULTS High risk HPV was detected in 6(42.8%) patients, and 6(5.3%) control subjects which was statistically significant (p<0.0001). HPV-18 was the most frequent type both in the cases and controls. HPV-16 DNA was detected in two patients of the case group, but it was not detected in any of the controls. The relation between demographic and risk factor variables was not statistically significant. CONCLUSION HPV infection has a significant impact on HNSCC. Despite HPV-16 stronger impact, HPV-18 is more likely to cause malignant degeneration in such cancers amongst some communities. It is vital to introduce and conduct immunization schedules in health care systems to protect communities to some extent.

Abstract
Novel drug delivery systems such as nanoparticles (NPs) have been proved to enhance the effectiveness of many drugs. Clarithromycin is a broad spectrum macrolide antibiotic, used in many infectious conditions like upper and lower respiratory tract infections, and skin and other soft tissue infections. This paper describes the preparation and enhanced in vitro antibacterial activities of clarithromycin loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles. A modified quasi-emulsion solvent diffusion (MQESD) method was used to prepare clarithromycin (CLR) NPs. The antibacterial activity of the NPs was evaluated using the agar well diffusion method against Escherichia coli (PTCC 1330), Haemophilus influenzae (PTCC 1623), Salmonella typhi (PTCC 1609), Staphylococcus aureus (PTCC 1112) and Streptococcus pneumoniae (PTCC 1240). The inhibition zone diameters related to each nano formulation were compared with those for untreated CLR at the same concentrations. The results indicated that the mean inhibition zone diameters of NPs against all the bacteria tested were significantly higher than those of untreated CLR, particularly in the case of S. aureus. The increased potency of CLR NPs may be related to some physicochemical properties of NPs like modified surface characteristics, lower drug degradation, and increased drug adsorption and uptake.

Abstract
The aim of this study was to investigate the expression of membranous epidermal growth factor receptor in colorectal adenocarcinoma and it's correlation with clinicopathological features. Fifty formalin-fixed, paraffin embedded archival specimens of colorectal cancer were included randomly as cases. Immunohistochemical staining was performed to assess EGFR expression. The results were correlated with the clinicopathological features of colorectal tumor tissues. More than 1% of membranous EGFR expression was found in 24 (48%) of cancer specimens. The immunoreactions intensity was classified as weak, moderate and strong representing 2, 22 and 24%, respectively. According to multivariate analysis, EGFR expression was not significantly associated with age, sex, tumor site, stage, grade and type of tumor in cases. These results suggest that the assessment of EGFR expression in colorectal cancer by conventional immunohistochemistry has not proven its predictive value and can not be useful to predict about outcome of patients.

Abstract
This study was done to consider relationships of luteal phase variables (prior to AI) with follicular waves. The estrous cycles of 15 buffaloes were synchronized with 2 i.m. injections of prostaglandin F2α given 11 days apart. The buffaloes were randomly assigned to 1 of 3 treatments. Buffaloes in the control treatment received no treatment, whereas G6 buffalos received a GnRH injection between Day 5 and 7 and G16 buffalos received a GnRH injection between Day 15 and 17 of the estrous cycle (estrus = Day 0). Daily, from estrus Day 0 to the next estrus Day 23, buffaloes had their ovaries scanned by ultrasound. Blood samples were collected by tail following each ultrasound examination from estrus until next estrus (estrus = 0). Concentrations of plasma progesterone were determined by radioimmunoassay kit. The limit of detection of the assay was 0.1 45 ng mL-1 and the intra- and interassay coeffients of variation were 7.4% and 9.2%, respectively. Data were analyzed by using PROC GLM of SAS (SAS Institute, Cary, NC, USA). For comparisons between groups, the 2-sample t-test was used for continuous traits, such as size of CL or hormone concentrations. Prospective comparisons of indices of progesterone indicated that the length of luteal lifespan was longer in 3-wave than in 2-wave buffaloes (P < 0.01). Plasma progesterone concentrations were similar at peak and measured as area under the curve on Day 5 through 17 preceding insemination in 2-wave (5.30 ± 0.40 ng mL-1) and 3-wave buffaloes (5.10 ± 0.20 ng mL-1). Length of the luteal phase (defined as from the day of estrus until the last day on which plasma progesterone remained >2 ng mL-1) was <2 days shorter in 2-wave buffaloes than in 3-wave buffaloes (15.20 ± 0.40 v. 17.10 ± 0.50 d; P < 0.05). In addition, the day of peak progesterone occurred earlier in 2-wave buffaloes (13.50 ± 0.30 v. 15.30 ± 0.70 d; P < 0.05).

Abstract
Historically, the recommended treatment for paranasal sinus mucoceles is the complete excision of through an open approach to achieve a cure. Though with the advent of Endoscopic sinus surgery, transnasal Endoscopic sinus surgery has gained more attention in order to manage the sinus mucocele. The aim of this study is to present the efficacy of the Endoscopic marsupialization of sinus mucoceles. From 2001 to 2005, 18 patients with paranasal sinus mucoceles were treated endoscopically. This series includes 6 fronto-ethmoidal, 2 maxillary, 4 ethmoid, 2 sphenoid, and 4 middle turbinate. The presenting signs, symptoms, and radiological findings were reviewed. All patients underwent endoscopic-wide marsupialization of the mucocele; the mean follow up was 13 months. There are 10 male and 8 female subjects who were of an age range of 29-72 years. Patients were treated with endoscopic marsupialization of the mucocele. There were no recurrences in the mean 13-month follow-ups in 17(94%) of patients. Only one patient needed revision endoscopic surgery. Mucocele happens to be the most commonly benign lesion, which causes the paranasal sinus to expand. There is increasing evidence that endoscopic marsupialization of sinus mucocele results in long-term control with very low recurrence rate at or close to 0%. Thus this technique is safe and less invasive than external approaches.

Abstract
Sheep (OAR), goat (CHI) and cattle (BTA) R-banded chromosome preparations, obtained from synchronized cell cultures, were used to FISH-map leptin (LEP) and solute carrier family 26 member 2 (SLC26A2) genes on single chromosome bands. LEP maps on OAR4q32 and CHI4q32, being the first assignment of this gene to these two species. SLC26A2 maps on BTA7q24, OAR5q24 and CHI7q24. This gene, too, was assigned for the fist time to both sheep and goat chromosomes, while it was more precisely localized on a single chromosome band in cattle. Improved cytogenetic maps of BTA4/OAR4/CHI4 were constructed and compared with HSA7 revealing five main conserved segments and complex chromosome rearrangements, including a centromere repositioning, differentiating HSA7 and BTA4/OAR4/CHI4.
