Regular red blood cell transfusions reduce the rate of recurrent cerebral infarction in sickle cell disease but lead to accumulation of excessive iron. We studied the effect on the prevention of recurrent stroke and the volume of blood transfused of a modified transfusion program in which the pretransfusion percentage of hemoglobin S (HbS) was maintained at 50%, rather than the conventional 30%...

Commercial exploitation of marine natural gas hydrate (NGH) is crucial for energy decarbonization. However, production would weaken reservoir mechanical properties and trigger geohazards. Experimental instruments are the basis to obtain responses hydrate-bearing sediments (HBS). Considering deformation processes from elastic residual during exploitation, this study comprehensively reviewed feas...

Submitted for the MAR08 Meeting of The American Physical Society How Large are Cooperative Effects in Hydrogen Bonded Molecular Chains? MARTIN FUCHS, MATTHIAS SCHEFFLER, Fritz-Haber-Institut der MPG, Berlin, Germany, JOEL IRETA, Univ. Autonoma Metropolitana Iztapalpa, Mexico — Intermolecular hydrogen bonds play an eminent role in a wide range of materials. In particular, they are critical for t...

Entecavir requires long-term administration. Pegylated interferon (PEG-IFN) therapy leads to significant reduction of hepatitis B surface antigen (HBs Ag) levels. This study aimed to assess the safety and efficacy of adding PEG-IFN-α-2a to entecavir toward cessation of entecavir. A total of 23 patients treated with entecavir underwent add-on PEG-IFN-α-2a therapy (90 μg per week) for 48 weeks. V...

BACKGROUND Hungry bone syndrome (HBS) is an important postoperative complication after parathyroidectomy for severe secondary hyperparathyroidism (SHPT). There is, however, little data in the literature on its detailed clinical course, and the associated risk factors remain controversial. METHODS We did a single-center retrospective study on 62 consecutive dialysis patients who underwent tota...

OBJECTIVE Patients with end-stage renal failure are at high risk of hepatitis B virus (HB V) infection. They have impaired immune response to HBV intramuscular (i.m.) vaccine. Non-response (anti HBs titer < 100mIU/ml) hemodialysis patients (HD) with the previous three-dose i.m. vaccination were examined with booster dose vaccine by i.m. , intradermal (i.d) and subcutaneous (s.c.) routes. MATE...

Materyal ve Metod: Çalışma tanımlayıcı- kesitsel bir çalışmadır. Çalışmaya Aile Sağlığı Merkezine periyodik muayene okul sağlık taramaları 84 çocuk dahil edilmiştir. edilen çocukların ailesinden çocuğun durumu, kronik ...

Hepatitis B adalah infeksi yang disebabkan oleh virus dan menyerang jaringan hati. Virus dapat menular melalui darah cairan tubuh penderita. Infeksi dicegah dengan melakukan vaksinasi. Kekebalan terhadap ditandai adanya kandungan Anti-HBs. Anti-HBs merupakan antibodi protektif B. Kadar sebesar ≥10 mIU/mL. Penelitian ini bertujuan untuk mengetahui profil anti-HBs pada mahasiswa Teknologi Laborat...

BACKGROUND Healthcare workers (HCWs) are at high risk for hepatitis B virus (HBV) infection. The aim of the study was to evaluate HBV immunization status and anti-HBs titer among HCWs. METHODS AntiHBs titer was prospectively examined in all vaccinated of the 464 HCWs enrolled. A comparison was done between two groups who had received vaccination within or beyond 5 years (Group A >5 years, Gro...

Objectives: Hepatitis B virus infection and associated diseases are a major public health problem. This study was planned to find out the persistence of antibody against hepatitis B surface antigen in Iranian vaccinated children after five years. Methodology: Anti-HBs titers in a group of healthy good – responder children who were vaccinated with Cuban hepatitis B vaccine in infancy were measur...
