OBJECTIVE Many forms of contraception are available on prescription only for example, the oral contraceptive pill (OCP) and long-acting reversible contraceptives (LARCs). In this analysis we aim to identify key determinants of prescription contraceptive use. DESIGN Cross-sectional population survey. Data on sociodemographic indices, concerns about the OCP and perceived barriers to access were...

This article formulates and solves a multiobjective fast charging-minimum degradation optimal control problem (OCP) for lithium-ion battery module made of series-connected cells equipped with an active balancing circuitry. The in the are subject to heterogeneity induced by manufacturing defects nonuniform operating conditions. Each cell is expressed via coupled nonlinear electrochemical, therma...

PURPOSE Increased stromal accumulation of macrophages and submucosal fibrosis due to excessive accumulation of collagens are central histologic features in ocular cicatricial pemphigoid (OCP). Interleukin (IL)-4 plays an important role in both the inflammatory and fibrotic events in several human and experimental diseases. In the present study, the possible role of IL-4 in the pathogenesis of O...

Herein, we show that the enhanced osteogenecity of octacalcium phosphate (OCP) biomaterial, recently identified as an important element in hybrid organic–inorganic nanocomposites involved initial hydroxyapatite crystal expansion mammal bones, results from chemical property, stemming presence lattice strain and dislocations. Two types OCPs were synthesized by wet-chemical processing (c-OCP) abse...

BACKGROUND It is noted that oral contraceptive pills increase the risk of abnormal Pap smear but results have been inconsistent across the populations. OBJECTIVE This study aimed to evaluate the association between oral contraceptive pill (OCP) consumption and abnormal Pap smear in women who referred to Shahid Sadoughi and Madar hospitals in Yazd. MATERIALS AND METHODS A cross sectional des...

Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

Online convex programming has recently emerged as a powerful primitive for designing machine learning algorithms. For example, OCP can be used for learning a linear classifier, dynamically rebalancing a binary search tree, finding the shortest path in a graph with unknown edge lengths, solving a structured classification problem, or finding a good strategy in an extensive-form game. Several res...

BACKGROUND Previous studies showed that octacalcium (OCP) collagen composite (OCP/Col) can be used to repair human jaw bone defects without any associated abnormalities. The present study investigated whether OCP/Col could be applied to dental implant treatment using a dog tooth extraction socket model. METHODS The premolars of dogs were extracted; each extraction socket was extended, and tit...

Statement of problem: It is not known whether endochondral and intramembranous bones have distinct biological characteristics. Octacalcium Phosphate (OCP), a hydroxyapatite precursor, has been reported to stimulate bone formation after being implanted in parietal bone defects of rats. Purpose: The present study was designed to investigate the response of endochondral and intramembranous bones t...
