چکیده هدف: مقایسه نتایج روش‌های جراحی اصلاح اکتروپیون سیکاتریسی در بیماران مراجعه‌کننده به بیمارستان لبافی‌نژاد بین سال‌های 82-1372. روش پژوهش: مطالعه به روش بررسی داده‌های موجود در پرونده بیمارستانی بیمارانی انجام شد که با تشخیص اکتروپیون سیکاتریسی به تنهایی یا همراه با سایر انواع اکتروپیون بین سال‌های 1382-1372 تحت عمل جراحی قرار گرفته بودند. یافته‌ها: از 84 بیماری که مورد بررسی قرار گرفت...
Administration of exogenous sulfidopeptide leukotrienes (LTs) is associated with enhanced microvascular permeability. In addition, endogenous LTs have been implicated as participants in permeability (nonhydrostatic) edema formation. The source of LTs for interaction with the microvasculature is, however, unknown. We hypothesized that pericytes contribute to vascular LT synthesis. Under basal co...
BACKGROUND The i-gel™, LMA-Supreme (LMA-S) and Laryngeal Tube Suction-D (LTS-D) are single-use supraglottic airway devices with an inbuilt drainage channel. We compared them with regard to their position in situ as well as to clinical performance data during elective surgery. METHODS Prospective, randomized, comparative study of three groups of 40 elective surgical patients each. Speed of ins...
Late talkers (LTs) — children who show a marked delay in vocabulary learning — have also been shown to differ from normally-developing (ND) children with respect to the semantic organization of their learned vocabulary. We use a computational model of word learning to study how individual differences between LTs and NDs give rise to differences in abstract knowledge of categories emerging from ...
Background: The Esophageal Tracheal CombitubeTM (ETC), Disposable Laryngeal Tube SuctionTM (LTS-D), and ProSeal Laryngeal Mask AirwayTM (PLMA) are devices that can secure the airway and maintain access to the stomach in at-risk patients, such as trauma or non fastened patients, when endotracheal intubation is difficult or impossible. Methods: We conducted a randomized controlled trial with the ...
BACKGROUND The NRG Oncology RTOG 9402 trial showed significant survival benefit in patients with 1p/19q co-deleted anaplastic oligodendrogliomas (AO) who received both radiation (RT) and chemotherapy (PCV regimen) versus RT alone. Substantial separation of the survival curves was only seen after 7.3 years. We aimed to determine whether there are specific genetic alterations that distinguish co-...
Many conditions can lead to laryngotracheal stenosis (LTS), most frequent endotracheal intubation, followed by external trauma, or prior airway surgery. Clinical management of these stenosis requires exact information about the number, grade, and the length of the stenosis. We have developed a method for assessment of LTS. The cross-sectional profiles (based on the central path) of the upper re...
Letter-to-sound (LTS) rules play a vital role in building a speech synthesis system. In this paper, we apply various Machine Learning approaches like Classification and Regression Trees (CART), Decision Forest, forest of Artificial Neural Network (ANN) and Auto Associative Neural Networks (AANN) for LTS rules. We used these techniques mainly for Schwa deletion in Hindi. We empirically show that...
BACKGROUND AND PURPOSE The lateral tentorial sinus (LTS) has not been well described in the imaging literature. The aim of this study was to investigate the value of MR imaging in assessing the LTS, which may provide guidance for preoperative planning. METHODS Fifty-five adult patients underwent MR imaging of the brain. Four neuroradiologists evaluated the studies for delineation of the LTS a...
The striatum is the largest nucleus of the basal ganglia and is crucially involved in action selection and reward processing. Cortical and thalamic inputs to the striatum are processed by local networks in which several classes of interneurons play an important, but still poorly understood role. Here we investigated the interactions between cholinergic and low-threshold spike (LTS) interneurons...
