Abstract

Health monitoring systems becomes a hot topic and important research field. Electrocardiogram (ECG) signal is a diagnoses tool that measures and records the electrical activity of the heart, taking care of patient’s health. Therefore, monitoring this signal becomes a necessary need to take care of human health. In this paper, two procedures are proposed; first, monitoring the ECG signal, second for sending the signal of monitoring patients and ECG data through Serial communication port to the other pc or nurse. AT89C51 microcontroller uses to perform these procedures including all the necessary connections of the microcontroller with other components and programming the microcontroller using assembly language to send the signal serially. At both transmitting and receiving sides, the signal was gives the same setting of baud rate, stop bits, number of data bits, parity to ensure secure arrival of data without any lossless.

أصبحت أنظمة مراقبة الصحة موضوعا بارزا ومجال بحث مهم في الحاضر. حيث تفسر أشارة تخطيط القلب بأنها أداة تشخيص التي تقوم بقياس وتسجيل النشاط الكهربائي للقلب والعناية بصحة المريض . لذلك أصبحت مراقبة هذه الأشارة ضرورية للأهتمام بصحة الأنسان. تم في هذا العمل دراسة مراقبة هذه الاشارة و كيفية أرسالها باستخدام الأرسال المتوالي . تم أستخدام المسيطر الدقيق لتنفيذ مراقبة الاشارة متضمنة برمجة المسيطر الدقيق بلغة الماكنة وأرسال الأشارة عن طريق الـ ((TXD PIN الى حاسبة اخرى ليتم تحليل الاشارة ورسمها باستخدام حزمة الماثلاب. في كلا جانبي الارسال والاستلام تم اعطاء نفس (Baud Rate), (Stop Bits), (Number of Data Bits) لضمان وصول الاشارة بدون اي خسارة. تم أختيار عدد محدود من ال((Samples لمحدودية حجم الـ (Buffers) في كلا الجانبين.

Abstract

ABSTRACT:BACKGROUND: Acute myocardial infarction is a major cause of death throughout the world. Many important advances have become available to Coronary Care Units enabling them to reduce mortality and improve the prognosis, Reperfusion therapy is one of these important advances. OBJECTIVE: This study sought to identify the Electro-cardiographic (ECG ) changes which occur after receiving Alteplase therapy and its relation to response to thrombolytic therapy. METHODS : Seventy-three patients with ST- elevation Acute Myocardial Infarction (AM I) who received Alteplase within 12 hours from the start of symptoms in coronary care unit were included in this study. Electro-cardiographic (ECG) was done to all patients at time of arrival to the coronary care unit(CCU), Alteplase therapy was given to all patients plus heparin intravenously, followed by electro-cardiographic (ECG ) every 30 minutes for 2 hours.RESULTS:Fifty-seven and half percent of our patients showed 50% reduction in the ST segment elevation in the worst lead after 2 hours from starting Alteplase therapy and regarded as responders. Other ECG changes like rapid appearance of Q wave, T inversion, accelerated idioventricular rhythm (AIVR) are found to be specific for reperfusion with a high predictive value when the gold standard criteria was reduction 50 % in the ST segment elevation Resolution of reciprocal changes is sensitive and specific with high predictive value. CONCLUSION :Some ECG changes after thrombolytic therapy can predict the response in addition to the already known changes. .

Abstract

Acute myocardial infarction is one of the commonest disease with serious complications and increasing morbidity and mortality. Coronary atherosclerosis plays a crucial role in the underlying pathophysiology. Fetuin-A is a protein which is closely linked with increased risk of cardiovascular disease, and secreted mainly by the liver, produces subclinical inflammation and insulin resistance. This study was aimed to evaluate the association of serum fetuin A level with ECG types of acute myocardial infarction.This is a case–control study included 88 subjects divided into two groups; 44 patients with acute myocardial infarction,36 of them with STEMI and 7 with NSTEMI. The other 44 were apparently healthy individuals taken as a control. Serum fetuin-A levels were measured by using ELISA technique. There was significant differences in serum fetuin-A levels between patients and control, (p value ≤ 0.05).The mean differences between serum fetuin-A levels and both type of AMI (STEMI and NSTEMI),were also significant(p value ≤ 0.05) where higher values observed in STEMI.This study concluded thatfetuin-A level was significantly correlated with type of AMI and higher values of fetuin-A were observed in STEMI .

Abstract

The objective of this study was to carry out an on-farm experiment in sheep owner farms in Kanaan district for the period from 7th Feb. 2015 to 27th Mar. 2015 and to identify the unconventional methods in controlling the reproduction in sheep and increase their productivity using 45 local Awassi ewes, randomly selected from three sheep owners (15 ewes / owner). Treatment group (10 ewes/ owner) were treated with a vaginal sponges containing 20 mg fluorogestone acetate (FGA) inserted for 10 days, followed by I.M. injection of 500 IU equine chorionic gonadotropin (eCG), while 5 ewes / owner were regarded as control group without any treatment. Estrus was observed for all ewes for 5 days post withdrawal of sponges. Ewes that showed estrus were mated by rams in their flocks, thereafter, pregnancy detection was conducted at days 35-37 post- mating using transabdominal ultrasonography. A questionnaire involved 20 sheep owners and a demonstrative field day was conducted for owners contributed in the experiment, and others from the region of study to explain the importance and results of the experiment. The results showed the appearance of estrus in all ewes 100% within three days after the withdrawal of sponges. Pregnancy rate of 85.71% at days 35-37 of mating. The questionnaire showed there is an urgent need of knowledge for owners to find out the importance of controlling the reproductive cycle in sheep using vaginal sponges. Also, there were a correlation between the need of knowledge for sheep owners with (educational level for most of them, herd sizes, income from breeding, training courses and other activities in the fields of breeding and reproduction of sheep). In conclusion, the technology of estrus synchronization has an important role to improve reproductive performance of sheep and pregnancy could be detected through transabdominal ultrasonography at 35-37 days with high accuracy as well as there is great desire for the most owner to conduct estrus synchronization technique and to take care their birth of herds simultaneously.

هدفت الدراسة اجراء تطبيق ميداني في حقول المربين في ناحية كنعان للمدة 7 شباط 2015 الى 27 آذار2015 للتعريف بالطرائق المتعلقة بالسيطرة على التناسل في الاغنام وزيادة انتاجيتها , تم اختيار 45 نعجة عواسية محلية عشوائيا من ثلاثة مربين بواقع 15 نعجة / مربي, مجموعة المعاملة (10 نعاج / مربي ) تمت السيطرة على الدورة التناسلية لها من خلال دفع الاسفنجات المهبلية المشبعة بـ 20 ملغم من البروجستيرون الصناعي fluorogestone acetate (FGA) لمدة 10 ايام ثم سحبها وحقن النعاج بهرمون equine chorionic gonadotropin eCG)) بجرعة مقدارها 500 وحدة دولية / نعجة, 5 نعجة / مربي عدت كمجموعة سيطرة دون اي معاملة, تمت مراقبة الشياع لخمسة ايام تلت سحب الاسفنجات, تم تلقيح النعاج التي اظهرت الشياع باستخدام كباش من نفس القطيع بعدها اجري فحص الحمل لعد 35- 37 يوم من التسفيد باستخدام جهاز الامواج فوق الصوتية , بعد ذلك اجريت استبانة لـ 20 مربياً وتنظيم مشاهدة حقلية ارشادية للمربين في المنطقة لايضاح نتائج واهمية التجربة, بينت النتائج ظهور الشياع في كافة النعاج المعاملة بالاسفنجات بنسبة 100 % خلال ثلاثة ايام بعد سحبها, و بلغت نسبة تشخيص الحمل في اليوم 35-37 بعد التلقيح 85.71%. اظهرت الاستبانة وجود حاجة معرفية ملحة للمربين للتعريف باهمية السيطرة على الدورة التناسلية في الاغنام, وجود علاقة بين الحاجة المعرفية للمربين والتحصيل العلمي لاغلبهم واحجام قطعانهم والدخل المتحقق من تربية الاغنام والدورات التدريبية والنشاطات التعريفية في مجال تربية واكثار الاغنام. يمكن الاستنتاج ان تقانة توقيت الشياع تؤدي دوراً مهماً في تحسين الاداء التناسلي في الاغنام وامكانية فحص الحمل بجهاز الامواج فوق الصوتية بعمر 35-37 يوماً بدقة عالية عن طريق جدار البطن فضلاً عن وجود رغبة كبيرة لدى اغلب المربين لتطبيق تقانة توقيت الشياع ورغبتهم برعاية المواليد بوقت واحد في قطعانهم.
