Usporedba učinaka Presynch-Ovsynch, Presynch-Ovsynch+CIDR i G6G protokola na reproduktivne pokazatelje Holstein krava u laktaciji u razdoblju nakon teljenja
This study was performed on an industrial dairy farm near Tehran province, Iran, on 666 lactating Holstein cows from September 2019 to June 2020 in order to eliminate the harmful effects of heat stress on the reproductive performance of the cows. The hypothesis of the recent study was that by increasing the serum concentration of progesterone (P4) in the luteal phase before insemination in the form of Presynch-Ovsynch+CIDR (POC) and G6G protocols, the pregnancy rate of cows would be increased compared to the Presynch-Ovsynch (PO) protocol. The aim of the present study was to evaluate the effects of Presynch-Ovsynch (PGF2α-14d- PGF2α-12d-Ovsynch (OVS: GnRH(GnRH1)- 7d-PGF2α(PG)-2d-GnRH)-18h-Fixed-time artificial insemination (FTAI), n=212), Presynch-Ovsynch+CIDR (similar to the PO protocol, plus the use of a CIDR for 7 days, from the start of the OVS+FTAI protocol to the time of PG injection, n=230), and G6G (PGF2α- 2d-GnRH-6d-OVS+FTAI, n=224) protocols on the reproductive performance and pregnancy rate of lactating Holstein cows. The average body condition score (BCS) for the cows was about 2.5 at the time of the onset of the OVS+FTAI program. The average daily milk production for cows at the time of the start of the OVS+FTAI program was 38.3 kg/day. On average, the studied cows were inseminated 86 days postpartum. Implementation of the G6G protocol in comparison to the PO and POC protocols increased the serum concentration of P4 at GnRH1 (P=0.04). The cows that received the G6G protocol had a greater number of corpuses luteum (CL) on their ovaries at PG in comparison to the cows in the PO and POC protocols (P=0.03 and P=0.05, respectively). For all treatment protocols, the pregnancy rate of cows with >2 CLs on their ovaries at PG was significantly higher than for cows with ≤2 CLs on their ovaries at this time. The overall pregnancy rate for all cows studied was 42%. Separately, pregnancy rates for cows in PO, POC, and G6G protocols were calculated at 36.7%, 41.7%, and 47.3% respectively. The highest and the lowest pregnancy rates were obtained in the G6G and PO protocols, respectively (P=0.03). It can be concluded that the G6G protocol increased the pregnancy rate of cows in comparison to the PO but not to the POC protocol. This result can be attributed to the increase in serum concentration of P4 at GnRH1 and the greater number of CLs at PG following implementation of the G6G compared to the PO protocol. Although CIDR administration in the POC protocol led to an increase in the pregnancy rate of cows compared to the PO protocol, possibly by increasing the synchrony rate and the quality of the ovulatory follicle, this increase was not statistically significant (P=0.09).Novija studija provedena je na industrijskoj mliječnoj farmi blizu Teheran provincije u Iranu, na 666 Holstein krava u laktaciji od rujna 2019. do lipnja 2020. godine u svrhu eliminacije štetnih učinaka toplinskog stresa na reproduktivne pokazatelje krava. Pretpostavka studije koja je prethodila ovom radu bila je da će se postotak gravidnosti krava, povećanjem koncentracije progesterona (P4) u serumu u lutealnoj fazi prije oplodnje putem Presynch-Ovsynch+CIDR (POC) i G6G protokola, povećati u usporedbi s Presynch- Ovsynch (PO) protokolom. Cilj ove studije bio je procijeniti učinke Presynch-Ovsynch (PGF2α-14d-PGF2α-12d-Ovsynch (OVS: GnRH(GnRH1)-7d-PGF2α(PG)-2d-GnRH)- 18h-fiksno vrijeme umjetnog osjemenjivanja (FTAI), n=212), Presynch-Ovsynch+CIDR (slično kao PO protokol, plus uporaba CIDR tijekom 7 dana, od početka OVS+FTAI protokola do vremena ubrizgavanja PG, n=230) te G6G (PGF2α-2d-GnRH-6d- OVS+FTAI, n=224) protokola na reproduktivne pokazatelje i postotak gravidnosti Holstein krava u laktaciji. Prosječno bodovanje stanja tijela (BSC) za krave bilo je oko 2,5 u vrijeme početka OVS+FTAI programa. Prosječna dnevna proizvodnja mlijeka za krave na početku OVS+FTAI programa bila je 38,3 kg/dan. U prosjeku, istraživane krave bile su osjemenjene 86 dana nakon teljenja. Implementacija G6G protokola u usporedbi s PO i POC protokolima povećala je koncentraciju P4 u serumu pri GnRH1 (P=0,04). Krave koje su primale G6G protokol imale su veći broj žutih tijela (CL) na svojim jajnicima kod PG u usporedbi s kravama u PO i POC protokolima (P=0,03, odnosno P=0,05). Za sve protokole liječenja, postotak gravidnosti krava koje su imale >2 žuta tijela na jajnicima kod PG bio je značajno veći od krava koje su u to vrijeme imale ≤2 žuta tijela na svojim jajnicima. Sveukupni postotak gravidnosti svih proučavanih krava bio je 42 %. Zasebno, postotci gravidnosti za krave u PO, POC i G6G protokolima izračunati su kako slijedi: 36,7 %, 41,7 %, odnosno 47,3 %. Najveći i najniži postotak gravidnosti postignuti su G6G, odnosno PO protokolom (P=0,03). Može se zaključiti da je G6G protokol povećao postotak gravidnosti krava u usporedbi s PO protokolom, ali ne i POC protokolom. Ovaj rezultat moguće je pripisati povećanju P4 koncentracije u serumu pri GnRH1 i većem broju žutih tijela kod PG nakon implementacije G6G protokola u usporedbi s PO protokolom. Premda je primjena CIDR u POC protokolu dovela do povećanja postotka gravidnosti krava u usporedbi s PO protokolom, moguće povećanjem sinkronizacijske stope i kvalitete ovulacijskog folikula, to povećanje nije statistički značajno (P=0,09)
Investigating the Relationship between Will Power and Spiritual Well-Being among Students: A Structural Equation Model
Backgrounds: Spiritual health is one of the important health dimensions, which helps stabilizing the person's internal characteristics and improves the individuals' quality of life. The aim of the study was to investigate the relationship between will-power and spiritual well-being of students in Shahroud University of Medical Sciences.
Methods: 431 students were evaluated by distributing the Paloutzian and Ellison Spiritual well-being Questionnaire and Iranian Will-Power Inventory. Spiritual health as a dependent variable, and power of will and the variables of gender, age, marital status, field of study, place of residence, and being native or non-native were measured.
Results: Regression results of structural equations showed that the demographic factors such as gender, marital status, educational level, and will-power variables predict the spiritual health score belonged to the students. The results also indicated that the will-power is associated with an increase in the spiritual health score of the students (beta=0.61, Pvalue=0.001).
Conclusions: Based on the findings, it seems that through the educational interventions and presentation of educational packages, strengthening of will-power is necessary for promoting the spiritual health of the students.

Chitosan/PEO nanofibers electrospun on metallized track-etched membranes: fabrication and characterization
The development of next-generation adsorption, separation, and filtration materials is growing with an increased research focus on polymer composites. In this study, a novel blend of chitosan (CS) and polyethylene oxide (PEO) nanofiber mats was electrospun on titanium (Ti)-coated polyethylene terephthalate (PET) track-etched membranes (TMs) with after-treatment by glutaraldehyde in the vapor phase for enhancing the nanofiber stability by crosslinking. The prepared composite, titanium-coated track-etched nanofiber membrane (TTM-CPnf) was characterized by Fourier transform infra-red (FTIR), water contact angle, and scanning electron microscopy (SEM) analyses. Smooth and uniform CS nanofibers with an average fiber diameter of 156.55 nm were produced from a 70/30 CS/PEO blend solution prepared from 92 wt. % acetic acid and electrospun at 15 cm needle to collector distance with 0.5 mL/h flow rate and an applied voltage of 30 kV on the TTM-CPnf. Short (15 min) and long (72 h)-term solubility tests showed that after 3 h, crosslinked nanofibers were stable in acidic (pH = 3), basic (pH = 13), and neutral (pH = 7) solutions. The crosslinked TTM-CPnf material was biocompatible based on the low mortality of freshwater crustaceans Daphnia magna. The composite membranes comprised of electrospun nanofiber and TMs proved to be biocompatible and may thus be suitable for diverse applications such as dual adsorption–filtration systems in water treatment

DATA
The current study was conducted on 663 cyclic lactating Holstein cows in one of the industrial farms near Qazvin province, Iran, from June 2119 to September 2020. We investigated the effects of equine chorionic gonadotropin (eCG) hormone administration 80 h before the implementation of the Ovsynch and fixed-time artificial insemination (OVS+FTAI) program in the form of the G6G protocol on pregnancy rate and reproductive parameters of dairy cows in the first postpartum insemination under heat stress conditions. The cows under study were randomly assigned to one of the following protocols and received the following treatments: G6G (PGF2α-2d-GnRH-6d-OVS+FTAI(GnRH(GnRH1)-7d-PGF2α(PG)-56h-GnRH-18h-FTAI, n = 213), 300e+G6G (PGF2α-2d-GnRH-64h-300IU,eCG-80h-OVS+FTAI, n = 231), and 500e+G6G (PGF2α-2d-GnRH-64h-500IU,eCG-80h-OVS+FTAI, n = 219). The overall pregnancy rates of cows in the G6G, 300e+G6G, and 500e+G6G protocols were 29.5 ± 0.03%, 33.7 ± 0.03%, and 35.6 ± 0.03%, respectively. The 500e+G6G protocol increased the pregnancy rate of cows with a BCS ≤ 2.5 compared to the G6G protocol (p = 0.04). The 500e+G6G protocol significantly increased the pregnancy rate of cows that produced > 34 kg milk per day compared to the G6G protocol (p = 0.03). In conclusion, using 500 IU, eCG 80 h before the implementation of the OVS+FTAI program in the form of G6G protocol had beneficial effects on increasing the pregnancy rate of cows that had a BCS ≤ 2.5 or produced > 34 kg milk per day compared to the G6G protocol under heat stress conditions.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Outcome of pancreaticoduodenectomy: Comparing the classic whipple with pyloric preservation
<b>Background: </b> The majority of patients presenting with periampullary neoplasms are operative candidates and are treated surgically. <b> Aim of the study: </b> To assess the complications, morbidity, mortality and 2-year survival rates, and safety of pancreaticoduodenectomy for periampullary carcinomas in a non-oncology surgical set-up. <b> Patients and methods: </b> Records of 23 patients underwent pancreaticoduodenectomy for periampullary cancers between July 1995 and April 2001 in Guilan, Iran, were reviewed. <b> Results: </b> Among 23 consecutive patients who underwent pancreaticoduodenectomy, 16 were men and 7 were women, and the mean age was 58 +/-10.2years. All the patients had a malignant neoplasm. Mean operative time was 7.3 hours. The surgical procedure was pylorus-preserving pancreaticoduodenectomy (PPPD) in 65%. The median intraoperative blood loss was 625 ml and no transfusion was required. There was no intraoperative mortality, and the overall 30-day postoperative mortality rate was 4.5%. Delayed gastric emptying was the most common postoperative complication. The 2-year survival rates for periampullary cancers were 93% in PPPD and 62.5% in classic Whipple procedure. <b> Conclusion: </b> Pancreaticoduodenectomy for periampullary tumors remains a formidable procedure in our set-up. It can be performed safely with low mortality and morbidity rate
بررسی تطبیقی رویههای شاخص برونگرایی شخصیت از منظر روانشناسی و متون اسلامی
خلفية البحث وأهدافه: إن الصفات الشخصية تعتبر من جملة المتغيرات المهمة في شرح السلوك. وقد دفع هذا الموضوع الكثير من الباحثين في علم النفس الى طرح نظريات مختلفة حول الشخصية. وقد كانت هذه الآراء دائماً موضع تكامل وعمل على رفع نواقصها. ومن جهة أخرى فإن دين الإسلام المبين قد طرح وصنف مجموعة واسعة من الصفات ودور كل واحدة منها في سلوك الأشخاص. والدراسة المقارنة بين هاتين الرؤيتين يمكنها فتح الأفق أمام رؤية دقيقة ومفيدة. وبناءً على هذا، فإن الهدف من هذا التحقيق الفعلي هو القيام بدراسة مقارنة لرؤى مؤشرات انفتاح الشخصية بمنظار علم النفس والنصوص الإسلامية.
منهجية البحث: يعتبر هذا التحقيق من نوع المطالعة المرورية بهدف استخراج وتحليل الرؤى المرتبطة بمؤشرات الانفتاح من النصوص التخصصية لعلم النفس والنصوص الإسلامية. أي أنه قد تمت الاستفادة من القرآن والحديث من خلال الدراسة المضمونية للآيات والروايات، ثم تم القيام بالدراسة المقارنة لرؤى انفتاح الشخصية بين نظرة علم النفس ونظرة النصوص الإسلامية. ولم يلحظ مؤلفو المقالة أي تقرير عن تعارض للمنافع فيما يرتبط بهذا التحقيق.
الكشوفات: إن جميع الرؤى الست لمؤشرات الانفتاح في علم النفس موجودة في النصوص الإسلامية أيضاً. ولكن هذه الرؤى مطروحة في النصوص الإسلامية بنحو أوسع من جهة سعة المفهوم والضوابط والمعايير. فرؤى مؤشرات الانفتاح قد تم تنظيمها في علم النفس من خلال الأخذ بعين الاعتبار للعوامل الخارجية والسلوكية فقط. بينما نجدها قد أخذت شكلاً من العلاقة الثلاثية في الإسلام بين الشخص والآخرين والله مع الأخذ بعين الاعتبار للعوامل النفسية والسلوكية. وبينما نجد أن الهدف لعلم النفس من شرح الرؤى هو تحسين الحياة الفردية والاجتماعية فإننا نجد أن الإسلام مضافاً إلى هذا الهدف فإنه يعتبر كل واحدة من هذه الرؤى تشكل أرضية للسعادة الأخروية.
الاستنتاج: بدون الاهتمام بالبُعد النظري والمعنوي فإنه لا يمكن الوصول إلى مفهوم واضح عن رؤى مؤشرات الانفتاح. فالميل نحو الله يمثل أرضية الارتباط الإنساني المطلوب مع الآخرين، كما أن الإسلام يهيئ أرضية الانفتاح الأكثر للأشخاص من خلال التدابير العملية والأحكام التشويقية والتكليفية.

Journal of Pizhūhish dar dīn va salāmat. 2020;6(3):139-156. https://doi.org/10.22037/jrrh.v6i3.23733Background and Objective: Personality traits are one of the important variables in explaining behavior. Many behavioral psychologists have been motivated to produce a variety of theories about personality. On the other hand, a wide range of characteristics and their roles in humans, performance have been classified and introduced. Matching these two view points can provide a more precise and useful viewpoint in this regard. The purpose of this study is compare the indicators of extroversion from the perspective of psychology and Islam.
Methods: This is a review study. For extracting and analyzing the indexes of extroversion, psychological books and sources and Islamic texts i.e. the Quran and the hadiths (statements from the Prophet and Imams) were used. Then, the indexes of extroversion were compared from the perspective of Islam and Islamic texts. The authors reported no conflict of interests.
Results: All the six indicators of extroversion in psychology can be found in Islamic texts as well, but in the latter, the concept and the criteria are more accurate and extensive than those in psychological texts. The indicators of extroversion in psychology have been merely based on behavioral and psychological factors while in Islam, there is a relational triangle between human, others and God, The purpose of psychology in explaining the indicators is individual and social well-being. But in Islam, in addition to this purpose, attention to each of the indicators provides the ground for eternal salvation.
Conclusion: Without taking the theoretical and virtual dimension into account, it is impossible to achieve an explicit meaning of the indicators of extroversion. Godliness paves the way for a desirable human relationship with others and Islam provides people with the opportunity to become more extroverted through practical measures and incentives.

روش کار: این پژوهش از نوع مروری است. برای استخراج و تحلیل رویههای مرتبط با شاخص برونگرایی از متون تخصصی روانشناسی و متون اسلامی یعنی قرآن و حدیث با بررسی محتوایی آیهها و روایات استفاده و سپس رویههای برونگرایی شخصیت از دیدگاه روانشناسی و متون اسلامی بررسی تطبیقی شده است. مؤلفان مقاله هیچگونه تضاد منافعی دربارۀ این پژوهش گزارش نکردهاند.
یافتهها: هر شش رویۀ شاخص برونگرایی در روانشناسی در متون اسلامی نیز وجود دارد اما در متون اسلامی رویهها از نظر وسعت مفهوم و ضوابط و معیارها گستردگی بیشتری دارد. رویههای شاخص برونگرایی در روانشناسی صرفاً با در نظر گرفتن عوامل روانی و رفتاری تنظیم شده، درحالیکه در اسلام مثلثی ارتباطی بین فرد، دیگران و خداوند با توجه به عوامل روانی، رفتاری و نگرشی شکل گرفته است. هدف روانشناسی از تبیین رویهها بهزیستی فردی و اجتماعی است؛ اما در اسلام علاوه بر این هدف، پرداختن به هرکدام از رویهها زمینهای برای سعادت اخروی محسوب میشود.
نتیجهگیری: بدون توجه به بُعد نگرشی و معنوی نمیتوان به مفهوم روشنی از رویههای شاخص برونگرایی دست یافت. خداگرایی زمینهساز ارتباط انسانی مطلوب با دیگران است و اسلام با تدابیر عملی و احکام تشویقی و تکلیفی، زمینۀ برونگراتر شدن افراد را فراهم میکند.
