The mean encapsulation efficiency of ethylcellulose or PLGA microcapsules was 52.4 or 76.9% for Hb and 86.4 or 74.7% for BSA, respectively. This demonstrates the effective use of centrifugation and the importance of an appropriate cosolvent system in the measure of encapsulation efficiency where one solvent dissolves the polymer while the other solvent quantitatively precipitates the liberated protein. It is evident that an alkaline solution of sodium dodecyl sulfate is efficient at quantitatively dissolving precipitated proteins. Remediation of problems observed with current methods and high reproducibility suggest that this modified method is generally applicable to the measure of protein encapsulation efficiency of polymer microcapsules.In December 2019, a new coronavirus infection was identified in China. Although the clinical presentation of COVID-19 is predominantly respiratory, more than 35%% of patients have neurological symptoms. We report an elderly female with asthenia, dry cough, anosmia, ageusia, fever, nausea, and a severe and persistent headache. She had confirmed COVID-19 using the nasal swab RT-PCR technique. Her cranial tomography was normal. The CSF analysis demonstrated a cell count of 21 cells/mm3 (80% lymphocytes and 20% monocytes), 34 mg/dl protein, and 79 mg/dl glucose. She improved after 4 days. Our report draws attention to the meningeal involvement of SARS-Cov-2. This study aimed to evaluate the clinical and radiographic mid-term results of short-stem THA in patients with DDH. We reviewed 32 cases that underwent Metha stem between November 2010 and February 2015. WOMAC scores, Oxford Hip Scores (OHS) and Harris Hip Scores (HHS) were recorded to evaluate the clinical results. The appearance of bone trabeculae development and stress shielding was analyzed. The mean age of patients was 50.3years (33-67) with the mean follow-up of 77months (60-106). According to Crowe cla
