Serum biochemical parameters are important aspects in the management of endangered species, such as Acipenser persicus. The values of these parameters can be used for confirming the maturity and for monitoring any changes in the quality of waters and related soils. Serum samples of 44 A. persicus fishes were analyzed and their serum parameter values were determined as Mean+/-SD in four groups: mature males and females and immature males and females, respectively. We compared the levels of calcium (Ca; 1.97 +/- 0.31-2.38 +/- 0.28 mmol/l), blood urea nitrogen (BUN; 4.4 +/- 0.54-6.16 +/- 0.63 mmol/l), cholesterol (CHO; 2.55 +/- 0.42-13.51 +/- 0.65 mmol/l), creatinine (CREA; 27.23 +/- 3.5-83.98 +/- 7.5 mmol/l), magnesium (Mg; 2.74 +/- 0.18-3.05 +/- 0.46 mmol/l), bilirubin (Bilirubin; 2.05 +/- 0.42-13.93 +/- 4.39 mumol/l), aspatate transaminase (AST; 18.25 +/- 1.5-167 +/- 38 Iu/l), alanine transaminase (ALT; 11 +/- 1-25.33 +/- 9.24 Iu/l), alkaline phosphatase (ALP; 183.5 +/- 17.68-523 +/- 66.23 Iu/l) and creatine kinase (CK; 157.5 +/- 27.58-2132.2 +/- 250.92 Iu/l). We have shown that there were no differences in the Ca and Mg levels among the different groups. However, mature females have higher CREA, AST, CHO and lower BUN, ALP and ALT than the immature females. In the mature males, the values of ALP and bilirubin were higher yet the values of CREA and ALT were lower than in the immature males.

Background: Cesarean section is one of the most common surgeries around the world. There are several different techniques for cesarean section. The most common techniques are Pfannenstiel-Kerr (PK) and the newer technique Misgav-Ladach (ML). The objective of this trial was to compare intraoperative and short-term postoperative outcomes between the Pfannenstiel-Kerr and the modified Misgav-Ladach techniques in primary cesarean deliveries. Methods: In a prospective controlled trial, 100 females were randomly assigned to the PK (n = 50) and ML (n = 50) groups. The two groups were compared in terms of duration of surgery and fetus delivery, blood transfusion, febrile morbidity, analgesic use, changes of hematocrit level, bowel transition time, wound infection /dehiscence and neonate five-minute Apgar score. Results: The duration of surgery and fetus delivery was significantly lower in ML than PK technique (P = 0.000). Analgesic use during the post-operative period was significantly lower in ML than PK (P < 0.001). There were no significant statistical differences between the groups in regards to drop of the hematocrit (P = 0.32), fever (P = 0.056) and bowel transit time (P = 1.000). The mean Apgar score of fifth minute was 8.80 ± 0.57 and 9.89 ± 0.42 in PK and ML groups, respectively (P < 0.001). Conclusions: Misgav-Ladach appears to be faster, requires shorter incision and less analgesic drugs than PK, which might lead to better postoperative outcomes.

BackgroundThere is a considerable rate of fertility failure and this causes a great burden of untoward effects for patients. Usually a considerable number of these patients undergo anesthesia for their treatment.ObjectivesThis study was designed to compare the effects of general and spinal anesthesia on these patients.Patients and MethodsIn a randomized clinical trial, after taking informed written consent from the patients, 200 patients entered the study; 100 in each. During a 2 year period, women aged 20 to 40 years entered the study (one group receiving spinal anesthesia and the other, receiving general anesthesia). Ovum retrieval protocols were the same. Nonparametric and parametric analyses were used for data analysis. P value less than 0.05 was considered significant.ResultsThere was no difference between the two groups regarding demographic variables. 15 of 100 patients (15%) in the general anesthesia group and 27 of 100 patients (27%) in the spinal anesthesia group had successful pregnancy after IVF; so, spinal anesthesia increased significantly the chance of IVF success (P value < 0.001; Chi Square).ConclusionsThe results of this study demonstrated that spinal anesthesia increased the chance of fertilization success.

Background: There is no doubt that problems during wakefulness can affect the quality and length of sleep. Sleep disturbances can have a serious negative effect on a person's ability, function, and overall well-being. One of the most important issues that can result in sleep disturbances is professional causes, and the most important of which is shift work. The present study aimed at investigating the association between shift work and various sleep disorders and quality of life. Methods: This was a cross-sectional study. The data were collected using the Persian version of Epworth sleepiness scale andSF-36 questionnaires to assess the participants' sleep disorder and quality of life. The questionnaires were filled in by 207 shift workers. Age, gender, shift works experience, and working experience were recorded for all participants.

A 480-g flowerhorn cichlid (an ornamental hybrid) with severe bilateral abdominal swelling, bulla-like structures on the skin, bilateral exophthalmia, and a prolapsed intestine was presented. Radiographs showed compression of the posterior part of the swim bladder and abdominal distention. Ultrasonography of visceral organs revealed a heterogeneous mass with hypoechoic to anechoic polycystic parenchyma and free fluid in the abdominal cavity. At necropsy, free fluid in the abdominal cavity and a large polycystic mass originating from the posterior kidney were observed. Histologically, the mass was composed of more cystic growth of tubules. The renal architecture was replaced by tubules, often irregular in shape, lined by simple to lightly stratified layers of neoplastic and pleomorphic cuboidal to columnar epithelial cells and the absence of glomeruli. Birefringent crystals were observed with polarized light within the lumen of some tubules. The apical border of the neoplastic cells was periodic acid-Schiff positive. Immunohistochemically, the neoplastic cells were positive for cytokeratin AE1/AE3 and proliferating cell nuclear antigen and were negative for p53 (tumor suppressor protein). Microscopic metastasis was seen in the spleen. The metastatic tumor was classified as a cystic adenocarcinoma of the kidney, originating from the proximal tubules.
