BACKGROUND Osteochondral allograft transplantation (OCA) is often performed with concomitant meniscus allograft transplantation (MAT) as a strategy for knee joint preservation, although to date, the effect of concomitant MAT on outcomes and failure rates after OCA has not been assessed. PURPOSE To determine clinical outcomes for patients undergoing OCA with MAT as compared with a matched coho...

To the Editor : Oculocutaneous albinism (OCA) is a genetically heterogeneous disorder manifested as a loss of pigmentation in the eyes, skin and hair (1). On the basis of its clinical presentation, OCA can manifest in either isolated or syndromic fashion under a variety of inheritance models (1). To date, four loci have been mapped for recessively inherited isolated OCA, and genes for all of th...

OBJECTIVE To assess the outcome of osteochondral allograft (OCA) transplantation as the primary treatment for cartilage injury in patients with no previous surgical treatment. STUDY DESIGN Case series. Patients were identified in our outcomes database. Patients undergoing primary OCA transplantation with no prior surgical treatment and a minimum of 2 years follow-up were selected. Pain and fu...

BACKGROUND Oculocutaneous albinism (OCA) is a heterogeneous and autosomal recessive disorder in all populations worldwide. The mutational spectra of OCA are population-specific. Some OCA patients carry mutations from different OCA genes. In this study, we investigated the frequency of digenic mutations in Chinese OCA patients. METHODS Genomic DNAs were extracted from the blood samples of 184 ...

In view of the limited information on the pharmacokinetics of oseltamivir (OSE) during pregnancy, this study aims to evaluate the placental transportation of OSE and its active metabolite oseltamivir carboxylic acid (OCA) in rats. A validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) system coupled to an in vivo transplacental model has been developed to determine OSE and OCA in...

the present study intended to propose a causal model of factors that would predict oral communication apprehension (oca) of iranian learners of english as a foreign language. to conduct the study, 135 male and female university students majoring in english were selected. five variables including: learners’self-esteem and introversion/extroversion(as independent variables), their gender and prof...

PURPOSE To report on the optic canal cross-sectional area (OCA) in Caucasian patients with normal-tension glaucoma (NTG) compared with Caucasian control subjects without known optic nerve (ON) diseases. METHODS Retrospective analysis of computed tomographic images of the cranium and orbits in 56 NTG patients (30 females and 26 males; 99 of 112 eyes; mean age 67.7 ± 11.1 years). Fifty-six age-...

Cole crops (Brassica vegetables) can pose a significant risk for N losses during the post-harvest period due to substantial amounts of readily mineralizable N in crop residues. Amending the soil with organic C has the potential to immobilize N and thereby reduce the risk for N losses. Four field trials were conducted to determine the effects of organic C amendments (OCA) on N dynamics and sprin...
