Abstract
Orexin-A (hypocretin-1) is a neuropeptide that is produced in the lateral hypothalamic area (LHA) and promotes widespread cortical activation. We investigated the effect of SB-334867, a selective orexin receptor 1 (OXR1) antagonist, on phospholipase C-β3 (PLCβ3) level using slices of rat hippocampus preparations and immunohistochemistry. We used three Wistar rats in each of three groups. The control group was untreated rats and SB vehicle and SB groups received SB vehicle and 10 mg/kg SB-334867 daily from postnatal day (PND) 12 to PND30, respectively. We found that the orexin receptor antagonist decreased the PLCβ3 level in the inner and outer blades of dentate gyrus (DG) compared to SB vehicle treated rats. Orexin may increase the PLCβ3 level in most regions of the rat hippocampus.

Abstract
Abstract
Introduction
Social relationships impact health through different mechanisms. Sleep problems are prevalent among adults in the USA, negatively impacting all-cause mortality, and increasing the risk for chronic diseases such as depression, cardiovascular disease, and cancer. This study aimed to assess whether the quality of an individual’s relationship with their significant other including support and strain, subjective relationship quality, joint decision making, marital risk, and conflict are associated with clinical, subjective, and objective measures of sleep.
Methods
Participants were selected from the Midlife in the United States (MIDUS) study if they had complete data on subjective sleep quality from the MIDUS II biomarker project and shared a bed with their partner (n=751, 49.5% female, Mage=53.4, SDage=11.2, range= 34–83). Subjective sleep quality was measured using the PSQI. A subset of these participants (n=246, 50.8% female) also completed 7-days of daily diary and actigraphy.
Results
Sleep disturbances were pervasive; 44.1% (n=331) of participants reported clinically meaningful sleep disturbances (PSQI>=5). Among the smaller sample of participants with 7-day sleep data, sleep disturbances were even more prevalent (60.9%). There were significant bivariate associations between higher support and lower strain with better subjectively and objectively sleep outcomes. Better subjective relationship quality was also associated with better subjectively measured sleep outcomes. Higher marital risk and more disagreement with partner were associated with poorer sleep. When accounting for all marital relationship factors, participants with higher support and lower strain given to partner had a better long-term sleep quality, b= 1.93, SE= .54, p<.001. Relationship quality was also associated with better daily sleep quality and daily reports of feeling rested, b = -.12, SE= .05, p=.023, and b= .11, SE = .048, p=.023, respectively. These relationships remained significant after accounting for age, current employment status, recent major health events, average daily caffeine, alcohol, exercise, and napping.
Conclusion
These findings support the importance of considering social determinants of sleep, suggesting that relationships with significant others may impact health through sleep quality. This highlights the importance of sleep as a transdiagnostic physiological mechanism that could be enhanced through improvements to relationships with significant others.

Abstract
BACKGROUND AND AIM The β-thalassemia major (β-TM) is defined as a hereditary red blood cell-related disease. Thrombotic events are associated with thalassemia in adult patients. Thus, the present investigation was aimed to examine some hemostatic parameters, including anti thrombin-III (AT-III), protein-C (PRC) and protein-S (PRS) in β-TM patients. METHODS Thirty B-TM patients who referred for routine follow-up admission to the thalassemia clinic of Kerman Special Disease Center alongside with 30 healthy subjects were selected and enrolled in the present study. Further registration, the peripheral blood specimens were collected after 3 weeks of last transfusion and then the plasma concentrations of AT-III, PRC and PRS were measured in them. RESULTS We have observed that the concentrations of natural coagulation inhibitors (PRC and PRS) were significantly attenuated in β-TM patients (P<0.05), while the plasma level of AT-III was not remarkably differed in β-TM patients in compare to healthy subjects. CONCLUSION According to the findings of present work, significant changes in the PRC, PRS and AT-III which could be observed in multi transfused β-TM patients may attribute as critical risk factors for the development of upcoming thromboembolic events in their future life.

Abstract
In this study, the effect of acidic extraction conditions (time of 30-90 min, temperature of 75-95 °C and pH of 1.5-3) on the yield and degree of esterification (DE) of citron peel pectin was investigated applying Box-Behnken design. The highest production yield of pectin (28.31 ± 0.11%) was achieved at extraction time of 90 min, temperature of 95 °C and pH of 1.5, as optimal extraction conditions, which was close to the predicted value (29.87%). Under optimum extraction conditions, the DE and the emulsifying activity were 51.33 and 46.2%, respectively. In addition, the emulsions were 93.9 and 93.5 stable at 4 °C, 93.7 and 93.1 at 23 °C after 1 and 30 days, respectively. The determination of flow behavior showed that the pectin solutions had a Newtonian behavior at low concentrations (< 1.0% w/v), while this behavior was changed to pseudoplastic with increasing concentration.

Abstract
1. The aim of this study was to establish how different moulting methods and body weight losses influenced post-moult performance and USDA egg weight distribution. 2. Data on 5 laying flocks (#34-38) of the North Carolina Layer Performance and Management Test were used in this meta-analysis. 3. The moulting methods were non-fasted moulted (NF), short feed restricted (SF), 13-d feed restricted (FR), non-anorexic moult programme (NA), non-anorexic moult programme with low sodium (NALS) as well as non-moulting programme as control treatment. The percentages of targeted body weight loss during the moulting period were 20, 24, 25 and 30% of body weight at the end of the first egg production cycle. 4. Post-moult egg production and egg mass were influenced by all moulting methods. Maximum increase in post-moult egg production rate and egg mass occurred with FR and NF programmes, respectively, at 30% of body weight loss, compared to non-moulted hens. Non-fasting methods reduced mortality rate more effectively than fasting methods. 5. Moulting resulted in increases in percentage of grade A and decreases in percentage of grade B eggs. Non-fasting methods increased percentage of grade A eggs more effectively than fasting methods. Percentage of cracked eggs decreased in moulted rather than non-moulted hens and the lowest rate was associated with the NA programme. 6. Post-moult egg weight was not significantly influenced by moulting methods. However, percentage of body weight reduction affected egg weight. The optimum increment in egg weight was achieved by 24% body weight reduction. 7. Overall, non-fasting methods resulted in similar egg production compared with fasting methods. Considering post-moult mortality and USDA egg weight distribution, non-fasting methods, especially NF and NA programmes, performed much better than fasting methods, indicating that non-fasting moulting methods, which are better for animal welfare, are effective alternatives to fasting methods.

Abstract
AIM Suppressive therapy with levothyroxine is the main step in treatment of differentiated thyroid cancer (DTC). However, subclinical hyperthyroidism is associated with deleterious effects on cardiovascular and skeletal systems. Metformin may have a suppressive effect on TSH level. METHODS We performed a single blind randomized controlled trial on the effect of short term Metformin therapy on 50 non-diabetic patients with DTC (mean age of 39.68 ±8.7 years) under suppressive therapy with levothyroxine. Metformin (500 mg) or placebo was added to the drug regimen of the patients and levothyroxine dose decreased by 33%. TSH and thyroid hormone values were measured at the beginning of the study and 3 months after treatment. RESULTS Forty-six patients had papillary and 4 had follicular carcinoma. The mean dose of levothyroxine was 2.2±0.48 µg/kg. The mean TSH level at the beginning of the study was 0.05±.04 mIU/L. The mean age, weight and baseline TSH level was not significantly different between metformin and placebo groups (P>0.2). In the metformin group, the mean (±SD) TSH level was significantly increased from 0.03±0.04 to 3.1±5.7 mIU/L after 3 months of intervention (P=0.01) and the mean thyroid hormone levels were significantly decreased (P<0.001). In the placebo group, the mean TSH level increased from 0.04±0.04 to 3.1±4.7 mIU/L after 3 months (P=0.003). Delta TSH was 3.0±5.6 mIU/L and 3.1±4.7 mIU/L in metformin and placebo groups, respectively (P=0.9). CONCLUSION Adding 500 mg of metformin to drug regimen was not useful to compensate for 33% of levothyroxine dose reduction in patients with DTC.

Abstract
The area of self-reinforced polymer composites is one of the fastest growing areas in engineering polymers, but until now these materials have been mainly developed on the basis of thermoplastic fibers of moderate performance. In this work, we report on a new type of self-reinforced composites based on high-performance aramid fibers to produce an "all-aramid" composite by applying a surface-dissolution method to fuse poly(p-phenylene terephthalamide) (PPTA) fibers together. After immersion in concentrated (95%) sulphuric acid (H(2)SO(4)) for a selected period of time, partially dissolved fiber surfaces were converted into a PPTA interphase or matrix phase. Following extraction of H(2)SO(4) and drying, a consolidated all-aramid composite was formed. The structure, mechanical- and thermal properties of these single-polymer composites were investigated. Optimum processing conditions resulted in unidirectional composites of high reinforcement content (approximately 75 vol %) and good interfacial bonding. The all-aramid composites featured a Young's modulus of approximately 65 GPa at room temperature, and a tensile strength of 1.4 GPa, which are comparable with or exceed the corresponding values of conventional aramid/epoxy composites. However, since fiber, matrix and interphase in all-aramid composites are based on the same high-temperature resistant PPTA polymer, a high modulus of approximately 50 GPa was maintained up to 250 degrees C, demonstrating the potential of these materials for high-temperature applications.

Abstract
This study was undertaken to describe clinical, mycological and histopathological findings in black neck ostriches affected with severe aspergillosis in a flock including 80 birds, near Tehran, Iran. The signs included anorexia, depression, notable weight loss, diarrhoea, severe respiratory distress and death. Grossly, the lungs showed numerous white to yellow caseous nodules and the walls of the thoracic and abdominal air sacs were thickened with inflammatory exudates containing cellular debris, necrotic masses and green mold colonies. Multiple nodules were observed in the liver, spleen and gastrointestinal tract as well. Histopathologically, there were conidial heads and fungal hyphae in the air sacs and multifocal necrotic and granulomatous lesions with septated and dichotomously branched hyphae in various tissues, which were stained with haematoxylin and eosin and Grocott's methenamine silver nitrate. Aspergillus fumigatus was isolated in various tissues taken from affected ostriches.

Abstract
Radionuclide thyroid scanning of patients with Hashimoto's thyroiditis (HT) may mimic other thyroid disorders including cold nodules, multinodular goiter and rarely hot nodules. The association of single hot nodules in such patients in the face of primary hypothyroidism has not been previously reported. We describe 6 female patients with HT who presented either with symptoms of overt thyroid failure or a sensation of lump in the neck (and later found to have mild thyroid failure) who had single firm thyroid nodules. These nodules were hot by both 99mTc pertechnetate and radioiodine thyroid scans. In three of 4 patients followed up for longer than 6 months on adequate thyroid replacement therapy the nodules regressed by up to 60%. Given "Best practice" recommendations patients with thyroid failure and single thyroid nodules would not be submitted to radionuclide scanning and this presentation of HT would have gone undetected.
