Pseudohypoparathyroidism (PHP) type 1b is a rare childhood disorder characterized by renal resistance to parathyroid hormone (PTH) resulting in biochemical hypoparathyroidism but with skeletal sensitivity to PTH. We describe a patient with PHP type 1b who we believe is one of the youngest reported patients with bilateral slipped capital femoral epiphyses (SCFE).
The population health perspective (PHP) is commonly used in addressing a wide range of health issues. In this article, the determinants of health that are an integral part of the PHP are used as a framework in considering the range of outcomes associated with exposure to child maltreatment. The article examines the strengths and limitations of the perspective and outlines directions for further...
هدف از انجام این مطالعه تعیین شاخص‌های داپلر سرخرگ‌های آئورت شکمی و اینترارنال در گربه‌های سالم و بالغ از نژاد مو کوتاه اهلی بود. اندازه‌گیری‌ها توسط اولتراسونوگرافی داپلکس داپلر صورت پذیرفت. در این بررسی 20 گربه مو کوتاه اهلی (10 عدد نر و 10 عدد ماده) مورد مطالعه قرار گرفتند. با استفاده از روش بیوپسی سوزن هسته‌ای، تحت گاید سونوگرافی نمونه‌های بافتی از کلیه راست و چپ حیوانات، جهت تعیین سلامت کل...
شبکه های عصبی ضربانی به منظور شبیه تر کردن شبکه های عصبی واقعی به شبکه های عصبی مصنوعی ایجاد شدند . درااین شبکه ها نقش عامل زمان از اهمیت ویژه ای بر خوردار است. یکی از شبکه های عصبی کلاسیک که تاکنون به شیوه ضربانی مدل نشده است شبکه learning vector quantization یا lvq است. در این پروژه ما بر آن شدیم تا علاوه بر طراحی و پیاده سازی ضربانی این شبکه تمهیداتی را به کار بگیریم که نسبت به بعضی از شبکه ...
The problem of minimizing a quadratic function of boolean variables, which we call PHP (positive half-product), is formulated. A fully polynomial time approximation scheme (FPTAS) for PHP is derived. Several NP-hard scheduling problems can be formulated in terms of PHP. In this presentation, we concentrate on a single machine scheduling problem with controllable job processing times to minimize...
PURPOSE To estimate the usefulness of preferential hyperacuity perimetry (PHP) in detecting conversion of early to late age-related macular degeneration in the Carotenoids and co-antioxidants in patients with Age-Related Maculopathy, a multicenter randomized controlled clinical trial. METHODS This was a nested case control study within the Carotenoids and co-antioxidants in patients with Age-...
BACKGROUND PCSK9 inhibitors (evolocumab and alirocumab) pose a challenge of sustainability because the potential patients are extremely numerous and the budget impact at the drugs' full price would be prohibitive. We have studied the reimbursability of these agents by constructing a series of price-volume simulations that used a model previously employed for sofosbuvir. METHODS Our price-volu...
Phosphopantetheine adenylyltransferase (PPAT) from Escherichia coli is an essential hexameric enzyme that catalyzes the penultimate step in coenzyme A (CoA) biosynthesis and is a target for antibacterial drug discovery. The enzyme utilizes Mg-ATP and phosphopantetheine (PhP) to generate dephospho-CoA (dPCoA) and pyrophosphate. When overexpressed in E. coli, PPAT copurifies with tightly bound Co...
Pseudohypoparathyroidism (PHP) type Ia is characterized by hypocalcemia due to PTH resistance and by features of Albright's hereditary osteodystrophy, including short stature, obesity, subcutaneous calcification and brachydactyly. A wide variety of clinical and biochemical manifestations have been reported. We report two cases of PHP type Ia in duozygotic twins with different phenotypes. The pr...
OBJECTIVES Patients with primary hyperparathyroidism (PHP), even asymptomatic, have an increased cardiovascular risk. However, data on reversibility or improvement of cardiovascular disorders with surgery are controversial. Our aims were to assess the prevalence of classic cardiovascular risk factors in patients with asymptomatic PHP, to explore their relationship with calcium and PTH levels, a...
