  To be effective, leaders need flexible access to their whole brain. Understanding how the human brain works and knowing how to best use the logical and social brain can provide a critical course for effective leadership. The present research by investigating 30 people from government and non-government sector managers and simultaneously recording the brain waves and heart wave rhythm of these people while performing the cognitive task of evaluating the response control and risk-taking of decision-making CGT (CANTAB software) with the Procomp 2 coherence evaluation device EEG describes heart wave rhythm (HRV) based on neuroscience and neurocardiology. The findings showed that the correlation coefficient test of brain waves and heart waves in both resting and performing cognitive tasks had significant differences from each other, so that there is no similarity between the coherence of EEG and ECG in the resting state with the time of performing the cognitive task of CGT among government and non-government sector workers. was not observed. These results show that the changes in brain and heart waves of people during rest and decision time are different from each other, so that the changes in brain waves and heart waves and the cooperation of these waves with each other depend on the environmental, mental and emotional conditions of people.

  Theileriosis is an important protozoal disease of domestic ruminants especially cattle, sheep and goats which is transmitted by various species of Theileria infected ticks. Anemia, electrolytic disorders and vasculitis are amongst the cardiovascular complications of theileriosis. In this study, 90 cows with theileriosis were evaluated by clinical examination, parasitologic tests and electrocardiography. In Theileria infected cattle, after 30 minutes of rest and any treatment, a 30 second ECG was recorded in lead I to determine the types of arrhythmias present. Based on electrocardiographic findings frequently observed arrhythmias included 62 cases of sinus tachycardia, 15 cases of sinus arrhythmia, 6 cases of first degree atrio-ventricular block, 1 case of ventricular extra systole and 1 case of atrial fibrillation. According to the type of arrhythmias, it can be concluded that arrhythmias in cows with theileriosis are functional and nonpathologic.   Manuscript profile

     Hypokalemia in sheep causes cardiac arrhythmia and electrocardiographic changes such as changing the shape of QRS,complex and T wave and the distance between waves. In this study, 20 rams with the age of 12-15 months were divided into two groups. Electrocardiography was used to check the heart rhythm. After recording ECG and sampling, in order to create hypokalemia Isoflupredon acetat at a dose of 4mg was used intramuscularly in oll 10 treatment. All P waves in the control and the experimental group was recorded as positive and their monophasic or diphasic state was also studied. Between days 0 to 4, 30 cases of monophasic and 20 cases of diphasic P wave was recorded is the control group. In the treatment group, these figures were 21 and 29 cases respectively. Different shapes of QRS waves were seen  in both treatment groups .In the control group they were recorded as QRS in 10 cases, qrs in 15 cases and qRs in 25 cases with in the treatment  group it was QRS in 31 cases, Qrs in 1 case, qrs in 4 cases and qRs in 14 cases. By examining the ECG in the control group on days zero to 4th day, sinus arrhythmia and atrioventricular block was observed in 7 and 2 cases respectively and in the treatment group sinus arrhythmia, atrioventricular block, atrial premature contraction and sinus tachycardia was recorded in 14, 12, 3 and 5 cases respectively. The results indicated that various arrhythmias can be observed due to hypokalemia. As physiologic arrhythmias can lead to pathologic arrhythmias, the animals should be treated with anti-arrhythmia drugs. Manuscript profile

  Progestins are useful for hormonal prevention of pregnancy in humans and animals. Progestrone and medroxy progestrone acetate are used for treatment of premenopausal syndrome and decreasing complications of estrogen therapy after menopause. Prescription of progesterone in dogs is usually done to control or delay estrus. If this drug is used at anestrous it will inhibit the gonadotropin excretion beyond the basic level and it will prevent cycle from happening again in proestrus or at the beginning of estrus progesterone will prevent ovulation. Use of progesterone is not totally safe in bitches. It can cause several problems such as cystic endometrial hyperplasia and pyrometera. In this study the effects of medroxy progestrone acetat (MPA) on electrocardiographic changes are evaluated. After nutritional and environmental uniformity and other evaluations, the animals were divided into two groups with six bitches in each group. MPA was used at 10 mg/kg for the first group and 20 mg/kg for the second group. An ECG was recorded from the first group in time zero. MPA was injected intramuscularly and immediately after ECG recording and the time of injection was noted. Another ECG was recorded 0.5 and 2 hours after injection. The same process was repeated for the second group. It was observed that MPA at 20 mg/kg increased the heart rate and consequently PR interval and RR interval were decreased significantly in normal range. Also administration of drug at 10 mg/kg decreased the heart rate and increased PR interval, QT interval and RR interval significantly in normal range. It is probable that these observations are the result of MPAs dose dependent vasodilatory nature that induces the heart to exhibit compensative reactions such as increasing heart rate.

  گوسفند قزل یکی از نژادهای اصلی در شمال غرب ایران است که به منظور تولید گوشت، شیر و پشم پرورش داده می‌شود. بهبود تولید‪مثل این نژاد تأثیر معنی‌داری بر روی رشد اقتصادی کشاورزان منطقه خواهد گذاشت. بنابراین در پژوهش حاضر تأثیر استفاده همزمان از همزمان‌سازی فحلی (سیدر و eCG) و جیره فلاشینگ بر تولید‪مثل خارج از فصل در میش­های قزل تعیین شد. تعداد 114 رأس میش قزل 3 ساله به طور مساوی به سه گروه آزمایشی تقسیم شدند. گروه 1 به وسیله سیدر و eCG همزمان‌سازی شدند و 40 روز جیره فلاشینگ دریافت کردند. گروه 2 برای 40 روز جیره فلاشینگ دریافت کردند و گروه 3 (شاهد) هیچ تیماری را دریافت نکردند. قوچ‌ها نیز به صورت همزمان با میش‌ها جیره فلاشینگ دریافت کردند. سیدرگذاری به مدت 12 روز انجام شد، به دنبال برداشتن سیدرها هر یک از میش‌های گروه 1 مقدار 400 واحد eCG به صورت تزریق درون ماهیچه‌ای دریافت کردند. سپس، قوچ‌ها وارد گله میش‌ها شدند. پنجاه روز بعد از قوچ ‌اندازی از اولتراسوند برای تعیین آبستنی استفاده شد. نسبت بره‌زایی در گروه 1 مقدار 32/276 درصد و نسبت آبستنی 100 درصد بود. این نتیجه به طور معنی‌داری متفاوت با گروه 2 و 3 بود. اگر چه بهبود اندکی در درصد آبستنی در گروه 2 نسبت به گروه کنترل مشاهده شد، نتایج کلی پیشنهاد می‌کنند که فلاشینگ به تنهایی در فعال‌کردن سیستم تولید‪مثلی در خارج از فصل تولید‪مثلی مؤثر نیست. این پژوهش نشان داد که همزمان‌سازی با استفاده از سیدر و eCG به همراه جیره فلاشینگ یک روش مناسب برای بهبود تولید بره در خارج از فصل تولید‪مثلی در میش‪های قزل است.

  موفقیت در برنامه تلقیح مصنوعی در زمان ثابت بستگی به میزان بالای تخمک­گذاری در فاصله زمانی کوتاه مدت درمان دارد. استفاده از هورومون eCG در انتهای برنامه همزمان­سازی فحلی با افزایش میزان رشد فولیکولی منجر به تولید فولیکول بزرگ و حساس به تخمک­گذاری و افزایش میزان آبستنی در دام می­گردد. هدف از این تحقیق تأثیر تزریق eCG در انتهای برنامه همزمان­سازی فحلی و تلقیح در زمان ثابت با استفاده از سیدر (CO-Synch+CIDR) بر روی میزان آبستنی گاو­های شیری بود. تعداد 144 رأس گاو شیری با فاصله زمانی 55≥  انتخاب و در زمان شروع آزمایش سیدر داخل واژنی به همراه 100 میکروگرم GnRH دریافت نمودند. در روز هفتم آزمایش، تمامی دام­ها 500 میکروگرم PGF2α دریافت داشته و به دو گروه کنترل و درمان تقسیم گردید. دام­های گروه درمان 500 واحد بین المللی هورمون eCG نیز دریافت نمودند. سیدر در روز هفتم آزمایش خارج گردید. تلقیح مصنوعی تمامی دام­ها حدود 66 ساعت پس از خروج سیدر انجام گردید. سونوگرافی تخمدان­ها همزمان با تلقیح تمامی دام­ها به منظور بررسی اندازه فولیکول غالب صورت گرفت. افزودن eCG در انتهای برنامه (co-synch) باعث افزایش میزان فراوانی میزان بروز فحلی (گروه درمان: 8/87 درصد، گروه کنترل: 4/51 درصد) گردید (01/0P<). فاصله خاتمه درمان تا آغاز علائم فحلی در گروه کنترل (52/5±7/56 ساعت) طولانی­تر از درمان (87/5±7/45 ساعت) بود (001/0P<). اندازه فولیکول غالب (41/2±1/15 میلی­متر) در گروه کنترل بیشتر از درمان (84/1±4/19 میلی­متر) بود. از سوی دیگر تزریق eCG تأثیری بر میزان آبستنی (گروه درمان: 4/54 درصد، گروه کنترل: 3/49 درصد) نداشت (131/0P=). به طور کلیاستقاده از هوزمون eCG، در انتهای برنامه 7 روزه در در برنامۀ (co-synch+CIDR) می­تواند سبب جلو انداختن زمان بروز فحلی گردد که باید در برنامه تلقیح در زمان ثابت گاو­های شیری مورد توجه قرار گیرد.

  The Myocardial infarction (MI) is the fail in reaching blood flow and sufficient oxygen to part of the heart. Te outbreak of MI symptoms might be various and the electrocardiography is not diagnostic in about 50% of the cases that is a potential danger for wrong diagnosis, therefore we need to test the cardiac biomarkers. In this survey the level of Troponin I serum in the diagnosis of the cardiac infarction with CK-MB serum, in 40 MI patients and 40 cardiac patients without MI of Seyyed Al Shohada Heart Hospital in Urmia has been evaluated and compared. the Troponin I through Immunoenzymometric method using AccuBind Kit and CK-MB through DGKC (German Society of Clinical Chemistry) method and IFCC (International Federation of Clinical Chemistry) using Pars Azmun Company kit through photometric method, measurement. and then Conducted  the results' statistical analysis using SPSS 21 software and an independent T-test The results achieved from the comparison between the cTnI and CK-MB of MI patients and patients without MI showed that there was a significant difference between the cTnI of patients without MI and MI patients and also the CK-MB of patients without MI and MI patients at the level of (P) and the cTnI and CK-MB of MI patients is more than patients without MI. therefore their use is necessary for on time diagnosis and treatment of Myocardial infarction. In this survey the cTnI and CK-MB was compared from the viewpoint of sensitivity and specification that regarding the results the cTnI sensitivity and specification with 100% and 97.5% respectively was more than the CK-MB sensitivity and specification with 91% and 75% respectively.
