BACKGROUND Tuberculosis contact investigation identifies individuals who may be recently infected with tuberculosis and are thus at increased risk for disease. Contacts with latent tuberculosis infection (LTBI) are offered chemoprophylaxis to prevent active disease; however, the effectiveness of this intervention is unclear as treatment completion is generally low. METHODS A retrospective coh...
BACKGROUND Consumer-reported patient-provider communication (PPC) assessed by Consumer Assessment of Health Plans Survey in ambulatory settings is incorporated as a complementary value metric for patient-centered care of chronic conditions in pay-for-performance programs. In this study, we examine the relationship of PPC with select indicators of patient-centered care in a nationally representa...
The KlPDA1 gene, encoding the E1alpha subunit of the mitochondrial pyruvate-dehydrogenase (PDH) complex was isolated from a Kluyveromyces lactis genomic library by screening with a 1.1 kb internal fragment of the Saccharomyces cerevisiae PDA1 gene. The predicted amino acid sequence encoded by KlPDA1 showed 87% similarity and 79% identity to its S. cerevisiae counterpart. Disruption of KIPDA1 re...
This study sought to quantitatively evaluate the reduction of radiation dose in coronary angiography and angioplasty with the use of image noise reduction technology in a routine clinical setting. Radiation dose data from consecutive 605 coronary procedures (397 consecutive coronary angiograms and 208 consecutive coronary interventions) performed from October 2014 to April 2015 on a coronary an...
The serum and red blood cell (RBCs) disposition of epirubicin (EPR) after intravenous bolus injection without and with coadministered quinine ( QUI) was investigated in patients undergoing a cyclic chemotherapy with EPR. QUI possesses a statistical significant influence on the EPR serum concentrations and, as a consequence, on the pharmacokinetic parameters for the initial distribution phase of...
Background—Outcome data for patients receiving implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy– defibrillator (CRT-D) devices treated outside of clinical trials are lacking. No clinical trial has evaluated mortality after device implantation or after shock therapy in large numbers of patients with implanted devices that regularly transmit device data over a ne...
عملکرد دانه و روغن، اجزای عملکرد، صفات زراعی و درصد روغن 18 ژنوتیپ بهاره کلزا در یک آزمایش دو ساله با شرایط آب و هوایی متفاوت (83-1381)، در قالب طرح بلوک های کامل تصادفی با چهار تکرار در ایستگاه تحقیقات کشاورزی گنبد بررسی گردید. نتایج تجزیه مرکب دو ساله داده های آزمایش نشان داد که اثر سال بر طول دوره رشد، تعداد دانه در خورجین، وزن هزار دانه و عملکرد دانه و روغن در سطح یک درصد معنی دار بود. اگرچ...
هر روز میزان استفاده از سوخت های فسیلی و بهای آن افزایش و منابع آن کاهش می یابد. به همین علت استفاده از منابع تجدیدپذیر انرژی و تولید سوخت های زیستی(بیواتانول) مورد توجه قرار گرفته است. یکی از مناسب ترین مواد اولیه برای تولید سوخت های زیستی ترکیبات سلولزی می باشد. از مهمترین میکروارگانیسم های تولید کننده ی آنزیم سلولاز قارچ trichoderma reesei می باشد. کمپلکس سلولازی شامل 3 آنزیم اندوگلوکاناز، ا...
. Alex Vitkin niversity of Toronto and Ontario Cancer Institute epartment of Medical Biophysics, Biophysics and Radiation Oncology oronto M5G 2M9, Canada Abstract. Interstitial quantification of the optical properties of tissue is important in biomedicine for both treatment planning of minimally invasive laser therapies and optical spectroscopic characterization of tissues, for example, prostat...
We consider a problem of finding optimal contracts in continuous time, when the agent’s actions are unobservable by the principal, who pays the agent with a one-time payoff at the end of the contract. We fully solve the case of quadratic cost and separable utility, for general utility functions. The optimal contract is, in general, a nonlinear function of the final outcome only, while in the pr...
