Effects of different carbohydrate sources on activity of rumen microbial enzymes and nitrogen retention in sheep fed diet containing recycled poultry bedding

In a completely randomized design, 15 male Moghani sheep were fed to determine the influence of supplementing recycled poultry bedding (RPB) with different carbohydrate sources on the activities of rumen hydrolytic enzymes and nitrogen retention. In the first diet, corn and barley were used as the carbohydrate sources (M0). In the second and third diets, corn and barley were replaced by 50 (M50 diet) and 100 (M100 diet) g/kg of sugar beet molasses, respectively. The extracellular activity of carboxymethyl-cellulase (CMCase) was increased linearly by dietary inclusion of molasses [linear (L), P  .05) by dietary inclusion of molasses. Dietary inclusion of molasses in RPB-containing diets linearly increased filter paper degrading (FPD) activity in all fractions of ruminal content (L, P < .05). Addition of molasses to the diets linearly decreased (L, P = .04) total activity of α-amylase, and cellular and total activity of proteases. Increasing dietary levels of molasses linearly increased retained N (L, P < .05). In conclusion, dietary supplementation of RPB-containing diet with molasses improved activities of fibrolytic enzymes and nitrogen retention in sheep

Performance and ruminal parameters of fattening Moghani lambs fed recycled poultry bedding

This study investigated the effects of recycled poultry bedding (RPB) on performance and protozoa population, microbial enzyme activity and microbial protein synthesis (MPS) in rumen contents of fattening lambs. Thirty-six male Moghani lambs (31.4 ± 3.2 kg body weight) were fed iso-energetic and iso-nitrogenous diets containing 0, 70, 140 or 210 g/kg dry matter (DM) RPB in a balanced randomized design (9 lambs per treatment). Results showed that final body weight, DM intake, average daily gain and feed conversion ratio were unchanged (P > 0.05) by RPB inclusion. Total protozoa population and sub-family of Entoniniinae and Diplodiniiae were linearly decreased by RPB (L, P  0.05) by feeding the experimental diets. Inclusion of RPB in the diet linearly decreased extra cellular and total α-amylase activity (L, P  0.05). The extra cellular activity of proteases tended to increase (L, P = 0.07) and their total and cellular activity increased (P > 0.05) in lambs fed RPB. Incorporation of RPB into the diet had no effect (L, P > 0.05) on urinary purine derivative excretion and MPS. In conclusion, inclusion of RPB up to 210 g/kg DM had no negative impact on performance, ruminal fibrolytic enzyme activity and MPS, while it increased rumen protease activity and decreased protozoa population in fattening Moghani lambs

Effect of Psychological Intervention on Marital Satisfaction of Mothers with Slow Pace Under 5 Years Children

Objectives: Objective of this study was investigating impact of early psychological interventions on marital satisfaction of mothers with slow pace under 5 years children. Considering variables of the research, that is, early psychological interventions and marital satisfaction, research hypotheses was as follows: &quot;early psychological interventions affect marital satisfaction of mothers with slow pace under 5 years children&quot; and it was examined.

They were assigned randomly into two groups of 20 (20 test group and 20 control group), and finally psychological interventions were conducted on one of groups randomly. In order to evaluate marital satisfaction, Enrich marital satisfaction questionnaire with 47 items was used. Data were analyzed by univariate analysis of covariance. Results: findings showed that there is significant difference between two groups in posttest in overall score of marital satisfaction as well as in some elements such as conventional responses, marital satisfaction, personality issues, marital relationships, conflict resolution, leisure, parenting, family and friends, and ideological orientation and sexual relations (P<0.005), and no significant difference was observed in financial supervision and roles related to gender equality. Discusion: Psychological interventions were effective in promoting marital satisfaction in mothers with slow pace under 5 years children

نقش پیش‏‌بینی‌کنندگی محبوبیت والدین و نشاط معنوی از احساس خودارزشمندی در نوجوانان دارای والد با آسیب بینایی در خانواده‌های تحت پوشش سازمان بهزیستی

سابقه و هدف: نشاط معنوی مقوله‏ای است که با وجود اهمیت فراوان آن به‏عنوان موضوعی مجزا کمتر به آن توجه شده است. نشاط لازمۀ زندگی و عامل محرکی برای نیل انسان به سلامت روانی و قُرب الی‏الله است. در عین ‏حال، عامل خانواده به‏ویژه محبوبیت والدین با بهزیستی روانی و کاهش آسیب‏های اجتماعی-روانی ارتباط معناداری دارد. ازاین‌رو، این پژوهش با هدف بررسی نقش پیش‏بینی‏کنندگی محبوبیت والدین و نشاط معنوی با احساس خودارزشمندی نوجوانان انجام شد. روش کار: پژوهش حاضر توصیفی از نوع همبستگی است. جامعۀ آماری همۀ نوجوانان دارای والد نابینای تحت پوشش سازمان بهزیستی در 31 استان ایران در سال 1400 بود که 240 نفر از آنان به‌روش نمونه‏گیری هدفمند و برحسب مراجعات متوالی به مراکز بهزیستی انتخاب شدند و پرسش‏نامه‌های احساس خودارزشمندی روزنبرگ، نشاط معنوی افروز و محبوبیت والدین افروز و اسدی را تکمیل کردند. برای تحلیل داده‏ها از ضریب همبستگی پیرسون و رگرسیون چندگانۀ سلسله‌مراتبی استفاده شد. در این پژوهش همۀ موارد اخلاقی رعایت شده است و مؤلفان مقاله تضاد منافعی گزارش نکرده‌اند. یافته‌ها: نتایج پژوهش نشان داد بین نشاط معنوی با احساس خودارزشمندی (63/0=r و 011/0>P) و همچنین بین محبوبیت والدین (52/0=r و 017/0>P) با احساس خودارزشمندی همبستگی مثبت و معنادار برقرار بود. تحلیل رگرسیون نشان داد به‏ترتیب نشاط معنوی توان تبیین 20% از واریانس احساس خودارزشمندی، نشاط معنوی و محبوبیت والدین با هم توان تبیین 28% از واریانس احساس خودارزشمندی؛ و محبوبیت والدین مستقل از نشاط معنوی توان تبیین 7% از این واریانس را داشتند. دو عامل محبوبیت مادر و پدر نیز توانستند 8% از واریانس احساس خودارزشمندی را پیش‏بینی کنند. در میان متغیّرهای مربوط به محبوبیت مادر و پدر، محبوبیت مادر با ضریب بتای 26/0=β قوی‏ترین پیش‏بینی‌کننده بود. نتیجه‌گیری: ازآنجایی‌که محبوبیت والدین و نشاط معنوی میزان بالایی از تغییرپذیری احساس خودارزشمندی را تبیین می‏کنند، می‏توان توجه به این عوامل را در بهبود احساس خودارزشمندی نوجوانان مهم دانست و در برنامه‏های ارتقای سلامت در جامعه مدنظر قرار داد

Electrochemical aptasensor based on the engineered core-shell MOF nanostructures for the detection of tumor antigens

Abstract It is essential to develop ultrasensitive biosensors for cancer detection and treatment monitoring. In the development of sensing platforms, metal-organic frameworks (MOFs) have received considerable attention as potential porous crystalline nanostructures. Core-shell MOF nanoparticles (NPs) have shown different diversities, complexities, and biological functionalities, as well as significant electrochemical (EC) properties and potential bio-affinity to aptamers. As a result, the developed core-shell MOF-based aptasensors serve as highly sensitive platforms for sensing cancer biomarkers with an extremely low limit of detection (LOD). This paper aimed to provide an overview of different strategies for improving selectivity, sensitivity, and signal strength of MOF nanostructures. Then, aptamers and aptamers-modified core-shell MOFs were reviewed to address their functionalization and application in biosensing platforms. Additionally, the application of core-shell MOF-assisted EC aptasensors for detection of several tumor antigens such as prostate-specific antigen (PSA), carbohydrate antigen 15-3 (CA15-3), carcinoembryonic antigen (CEA), human epidermal growth factor receptor-2 (HER2), cancer antigen 125 (CA-125), cytokeratin 19 fragment (CYFRA21-1), and other tumor markers were discussed. In conclusion, the present article reviews the advancement of potential biosensing platforms toward the detection of specific cancer biomarkers through the development of core-shell MOFs-based EC aptasensors
