چکیده مقدمه: امروزه جراحی محافظهکارانه که در آن تنها قسمتی از نسج پستان خارج میشود(Breast conserving surgery= BCS) روشی مقبول و استاندارد برای درمان سرطان پستان در شرایط خاص است ولی به نظر میرسد که در ایران از این روش بهطور محدود استفاده میشود. هدف: بررسی عملکرد جراحان عمومی در مورد BCS و عوامل مرتبط با آن. مواد و روشها: در این مطالعه مقطعی پرسشنامههای طراحی شده برای 300 جراح عمومی ...
This study aimed to establish whether sheep flock production losses due to nematode (worm) infections are typically greater in mature sheep selected for anthelmintic treatment at random compared to sheep selected for treatment based on low (poorer) body condition score (BCS). The study also examined the proportion of sheep in flocks that could be left untreated before production losses became e...
An experiment was conducted to determine the effects of high vs low body condition scores (BCS) produced by restricted feeding on reproductive characteristics, hormonal secretion, and leptin concentrations in mares during the autumnal transition and winter anovulatory period. Mares with BCS of 6.5 to 8.0 were maintained on pasture and/or grass hay, and starting in September, were full fed or re...
When the Automated Guided Vehicles (AGVs) are transferring the parts from one machine to another in a job shop environment, it is possible that AGVsstopon their guidepaths since their batteries are discharged.Consequently, it is essential to establish at least one Battery Charging Storage (BCS) to replace full batteries with empty batteries for the stopped AGVs. Due to non-predictable routes fo...
پژوهش حاضر به روش طولی آینده نگر بر روی 538زن باردار 35-18ساله با سن حاملگی زیر20هفته در فاصله اردیبهشت89تا90صورت گرفت. اطلاعات فردی با استفاده از پرسشنامه جمع آوری شده و شاخص توده بدنی (bmi) افرادبر اساس وزن قبل از بارداری محاسبه گردید. اطلاعات تغذیه ای با استفاده از پرسشنامه استاندارد بسامد مصرف مواد غذایی(ffq) محاسبه گردید. واحد های پژوهشی با توجه به شاخص توده بدنی قبل از بارداری بر اساس گرو...
هدف از این تحقیق بررسی شیوع چاقی و اضافه وزن و رابطه آن با سطح فعالیت بدنی در دانش آموزان پسر مقطع راهنمایی بود. نمونه های این تحقیق. 433 نفر از دانش آموزان پسر 11 تا 15 سال شهرستان زنجان بودند که از مدارس راهنمایی تحصیلی انتخاب شدند. نمونه گیری در دو مرحله انجام گرفت.
BACKGROUND Obtaining blood cultures (BCs) for patients hospitalized with community-acquired-pneumonia (CAP) has been recommended by experts and used as a measure of quality of care. However, BCs are infrequently positive in these patients and their effect on clinical management has been questioned. PURPOSE We performed a systematic review of the literature to determine the impact of BCs on cl...
Under tropical condition the BCS may influence the feed intake and metabolism leading to variation in economic parameters. This study investigated the BCS as a regulator of milk yield (MY) and composition (MC) in dairy animals. A total of 154 animals, comprising Azakheli (AZ) and Nili-Ravi (NR) buffaloes, Holstein Friesian (HF), Jersey (JC), Sahiwal (SW), Achai (AC) and crossbreds (XB) cattle a...
BACKGROUND Previous studies have shown a high incidence of complications with a bi-cruciate stabilized (BCS) guided-motion total knee arthroplasty (TKA) design, which led to recent modifications of the design by the manufacturer. OBJECTIVE The current study was undertaken to assess whether the use of this TKA system with an extension-first surgical technique is associated with a similar rate ...
Bipolar cells (BCs) are critical relay neurons in the retina that are organized into parallel signaling pathways. The three main signaling pathways in the mammalian retina are the rod, ON cone, and OFF cone BCs. Rod BCs mediate incrementing dim light signals from rods, and ON cone and OFF cone BCs mediate incrementing and decrementing brighter light signals from cones, respectively. The outputs...
