BACKGROUND To provide an estimate for the burden of neural tube defects (NTD) in low- and middle-income countries (LMIC) and explore potential public health policies that may be implemented. Although effective interventions are available to prevent NTD, there is still considerable childhood morbidity and mortality present in LMIC. METHODS A search of Medline, EMBASE, Global Health Library and...
A rapid on-site air sampling technique was developed with a miniaturized needle-type sample preparation device for a systematic evaluation of the indoor air environments in school facilities. With the in-needle extraction device packed with a polymer particle of divinylbenzene and activated carbon particles, various types of volatile organic compounds (VOCs) were successfully extracted. For eva...
Needle biopsy of small or nonpalpable breast lesions has a high nondiagnostic sampling rate even when needle position is guided by stereotaxis or ultrasound. We assess the feasibility of using a near-infrared fiber optic probe and computer-aided detection for the microscopic guidance of needle breast biopsy procedures. Specimens from nine consented patients undergoing breast-conserving surgery ...
The aim of this study was to compare the therapeutic effects of rhGH administered either by subcutaneous needle-injection (pens) or subcutaneous needle-free jet-injection (VISION(®)). Furthermore, a survey was carried out after using VISION(®) for 12 mo. A needle-free injection group consisting of 18 subjects (11 males and 7 females, mean age 5.87 ± 2.05 yr at the start of hGH therapy) who have...
Several mvestlgators hétve suggested that "upper" neural tube defects (NTD's) anencephaly, encephalocele, and thoracic spina blfida. are etiologica!ly dlfferent from "Iower" NTD's (Iumbo-sacral spina bifida) This hypothesis was primarily based on the observations that the two types have different sex ratios and recurrence rates and that the NTD cases within one sibship are concordant for NTD ty...
Proper analytical physically based model to predict fluctuations in the threshold voltage due to a single interface trap at a random location along the channel in a typical sub-50 nm MOSFET is of utmost significance. This research summary compares the efficacy of the existing analytical model based on dopant number fluctuation estimation in the channel of a MOSFET when compared to 3D Ensemble M...
The clinical safety, use and pharmacokinetics of a new needle-free device for delivery of growth hormone (GH) were compared with those of conventional needle injection devices. In an open-label, randomized, 4-period crossover study, 18 healthy adults received single subcutaneous injections of Genotropin administered by the Genotropin ZipTip needle-free device and by conventional injection. Bioe...
زمینه و هدف: ارزیابی صحیح مواجهه با ترکیبات آلی فرار، مهمترین گام اجرای اقدامات کنترلی برای این دسته از ترکیبات می باشد. روش نوین نمونه برداری تله سوزنی که دارای مزیت های روش های ریز استخراج در نمونه برداری از آلاینده های منتشره در هوا را می باشد، روشی ارزان و سریع است. در این مطالعه سعی شده عملکرد این روش در نمونه برداری از ترکیبات ارگانوهالوژن مورد بررسی قرار گیرد. روش بررسی: در این مطالعه، ع...
