BACKGROUND AND OBJECTIVE A recent FDA safety communication has discouraged the use of a power morcellator for myoma extraction and has called for a change in surgical techniques for myomectomy. The objective of this study was to compare surgical outcomes of laparoscopic single-, two-, and conventional three-port myomectomy and to evaluate the feasibility of contained manual morcellation for ute...
IDH1 SNP rs11554137 was recently reported in association with poor prognosis in normal karyotype adult acute myeloid leukemia (AML). We aimed to determine the prevalence, clinical associations, and prognostic significance of SNP rs11554137 in unselected pediatric and adult AML patients. Diagnostic marrow specimens from 527 AML patients treated on the pediatric trial Children's Oncology Group-AA...
Background. Esophagectomy for esophageal cancer is being practiced routinely with favorable results at many centers. We sought to determine if tumor histology is a powerful surrogate marker for perioperative morbidity. Methods. Seventy three consecutive patients managed operatively were reviewed from our prospectively maintained database. Results. Adenocarcinoma (AC) was present in 52 (71%) and...

The proceedings of this conference, “Amplification for Children ...
Lake deposystems are commonly associated with retroarc mountain belts in the geological record. These deposystems are poorly characterized in modern retroarcs, placing limits on our ability to interpret environmental signals from ancient deposits. To address this problem, we have synthesized our existing knowledge about the distribution, morphometrics, and sedimentary geochemical characteristic...

روش ساده، حساس، سریع و دقیق اسپکتروفتومتری برای اندازه گیری همزمان تتراسایکلین (TC)، اکسی تتراسایکلین (OTC) و داکسی سایکلین (DXC) در نمونه های عسل به کارگرفته شد. روش های کمومتریکس برای اندازه گیری ترکیباتی است که با یکدیگر هم پوشانی طیفی دارند. در این تحقیق، دو روش کالیبراسیون کمترین مربعات جزیی (PLS) و آنالیز فاکتورهای موازی ((PARAFAC برای اندازه گیری تتراسایکلین ها استفاده شد. محدوده...
A Mycoplasma hyopneumoniae vaccine (ResPiSure@,SmithKline Beecham Animal Health, Exton Pennsylvania) was tested for its effect on pig growth rate in a ISO-sow farrowto-ffnish unit in North Carolina using all-in-all-out flow in the farrowing and nursery. From October 1991 to December 1991, 625 nursery pigs from ffve weaned groups were sorted into pens by gender and similar weight, eartagged, and...
BACKGROUND To enhance the understanding of biological mechanisms connecting early adversity and negative health, we examine the association between family interpersonal violence and disruption and telomere length in youth. These specific exposures were selected because of their established links with negative health consequences across the life-course. METHODS Children, age 5 to 15, were recr...
OBJECTIVE To evaluate the urethroplasty learning curve. Published success rates of urethral reconstruction for urethral stricture disease are high even though these procedures can be technically demanding. It is likely that success rates improve with time although a learning curve for urethral reconstruction has never been established. MATERIALS AND METHODS We retrospectively reviewed anterio...
