The peripheral light-harvesting bacteriochlorophyll-carotenoid-protein complex B800-850 (LHII) has been isolated from membranes of semi-aerobic dark-grown cells of Rhodobacter sulfidophilus strain W4. A reversed-phase HPLC system resolved one beta- and one alpha-polypeptide in the ratio 1:1. The material obtained was of high purity and suitable for direct microsequence analysis. The primary str...

Six strains of Haemophilus influenzae were distributed to 417 United Kingdom laboratories who were asked to test susceptibility of the strains to ampicillin, augmentin, tetracycline, chloramphenicol, and trimethoprim and to test for beta lactamase production. Laboratories were also asked to provide details of their methods by completing a questionnaire. The incidence of reports recording sensit...

Introduction: Limited data are available on the effectiveness of antidepressants in the treatment of functional gastrointestinal disorders in children. We evaluated the effectiveness of citalopram in the treatment of childhood functional abdominal pain (FAP).   Material and Methods: Children with FAP (n=115, aged 6-18 years) received either citalopram 20 mg/day or placebo for 4 weeks. Tre...

Evaluation of the secondary structure of caldesmon from c.d. spectra revealed that it contains 51% helix, 9% beta-strand and 40% of remainder structures. These values agree well with the predicted ones from amino acid sequence, assuming an extended chain structure for caldesmon. The estimates of the secondary-structure elements in C-terminal 34 kDa and 19 kDa fragments are: 11 and 12% helix, 22...

Melanocytic skin tumors are caused by nevus cells, epidermal melanocytes and dermal melanocytes. The aim of the study was to detect the positivity of Demodex spp. in biopsy specimens of skin diagnosed as nevus. In this retrospective study, the specimens obtained from 110 patients diagnosed with nevus and stained by hematoxylin & eosin (H&E) method were assessed for Demodex. Statistical analysis...

Cardiac hypertrophy produced in vivo by pressure overload is characterized by selective up-regulation of the fetal/neonatal beta-cardiac myosin heavy chain (MHC) isogene. However, a molecular signal for beta-MHC isogene induction has not been identified. We examined cardiac MHC isogene expression in a cell culture model for hypertrophy. alpha-MHC and beta-MHC iso-protein and iso-mRNA levels in ...

Clusterin from bull rete testis fluid (RTF), cauda epididymal fluid (CEF), and octyl-beta-D-glucopyranoside extract of cauda epididymal sperm (CES) was identified and characterized using monoclonal and polyclonal antibodies (Abs) developed against ram clusterin and a beta-subunit-specific oligopeptide of porcine clusterin. One-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophores...

BACKGROUND Autoantibodies against synthetic peptides of beta-adrenergic receptors have been observed in human cardiomyopathy. However, it has never been shown that such antibodies really interact with native human beta-adrenergic receptors, nor has the clinical impact of such an interaction been investigated in larger groups of patients. METHODS AND RESULTS We screened 104 patients with dilat...
