Single-balloon enteroscopy (SBE) is designed for identifying possible small bowel lesions with balloon-assisted enteroscopy that allows deep intubation of the intestine. However, data regarding the outcome and safety of SBE remain limited. We conducted this study to evaluate the outcome and safety of anterograde and retrograde SBE approaches. This retrospective review from a tertiary medical ce...
TO THE EDITOR: Schizophrenic patients treated with antipsychotic drugs may suffer from a variety of sexually disabling side effects that can affect all domains of sexual activity. The most common such adverse effects in men are erectile dysfunction and retrograde ejaculation (1). Retrograde ejaculation has been mostly reported in association with typical antipsychotics, especially thioridazine ...
INTRODUCTION Endoscopic retrograde cholangiopancreaticography has been the treatment of choice for stones in the common bile duct. Although the procedure is usually safe, procedure-related complications do occur. CASE PRESENTATION A case of pancreatitis following endoscopic retrograde cholangiopancreaticography is described in a 55-year-old woman. After an uneventful recovery the patient's co...
conclusions retrograde laparoscopic appendicectomy using single polymer clip makes easy access to operating in complicated and non-complicated appendicitis. results four patients (15.4%) were converted to open surgery; three patients in group i and one in group ii. four patients developed postoperative complications; three patients in group i and one in group ii. operative time was less in grou...
We used a free-recall paradigm to establish a behavioral index of the retrograde and anterograde interference of emotion with episodic memory encoding. In two experiments involving 78 subjects, we show that negatively valenced items elicit retrograde amnesia, whereas positively valenced items elicit retrograde hypermnesia. These data indicate item valence is critical in determining retrograde a...
This study was designed to determine the efficiency and rate of testosterone (T) retrograde transfer during the follicular and luteal phase of the estrous cycle in gilts (n=27). The efficiency and the rate of the retrograde transfer of T from the ovarian effluent into blood supplying the ovary were determined for the first time under in vivo conditions. Ovarian arterial blood concentration of T...
Efficient retrograde access to projection neurons for the delivery of sensors and effectors constitutes an important and enabling capability for neural circuit dissection. Such an approach would also be useful for gene therapy, including the treatment of neurodegenerative disorders characterized by pathological spread through functionally connected and highly distributed networks. Viral vectors...
The role of the hippocampus in retrograde amnesia remains controversial and poorly understood. Two cases are reported of discrete bilateral hippocampal damage, one of which was a rare case of limbic encephalitis secondary to the human herpes virus 6. Detailed memory testing showed marked anterograde memory impairment, but only mild, temporally-limited retrograde amnesia that covered a period of...
Intracellular signaling from plastids to the nucleus, called retrograde signaling, coordinates the expression of nuclear and plastid genes and is essential for plastid biogenesis and for maintaining plastid function at optimal levels. Recent identification of several components involved in plastid retrograde generation, transmission, and control of nuclear gene expression has provided significa...
این پایان نامه به بررسی تجربی اثرات گرمایی تولید شده در ماده فعال لیزرهای حالت جامد که بصورت میله و از جنس بلورnd:yag است، بوسیله دیودهای لیزری که جهت دمش محیط فعال مورد استفاده قرار گرفته است، می پردازد. اثرات حرارتی موجب کاهش توان و کیفیت پرتو خروجی لیزر می گردد. دمش ماده فعال به دو صورت دمش جانبی و دمش انتهایی انجام می شود که در اینجا دمش انتهایی ماده فعال مد نظر است. ایجاد حرارت در محیط ف...
