An agar diffusion assay for chloramphenicol and tetracyclines is described, using inhibition of hemolysis by Clostridium perfringens as a biological indicator of antimicrobial activity. Well-defined zones formed after a 1.5- to 2-h incubation in an anaerobic chamber or after 3 h using a GasPak system. Serum levels of chloramphenicol as low as 2.0 mug/ml could be reproducibly determined with thi...

Recent years have seen an increase in the acceptance of green chemistry as a viable method for producing nanoparticles. The aim this work was to investigate cytotoxicity, antioxidant effect, and hemocompatibility zinc oxide nanoparticles (ZnO NPs) produced utilizing Capparis spinosa L. (C. L.) fruit extract powerful reducing agent. reaction rate ZnO NPs’ shape concerning concentration, contact ...

The study of bioactive compounds from marine animals has provided, over time, an endless source of interesting molecules. Jellyfish are commonly targets of study due to their toxic proteins. However, there is a gap in reviewing successful wet-lab methods employed in these animals, which compromises the fast progress in the detection of related biomolecules. Here, we provide a compilation of the...

Monocyte recognition of immunoprotein-coated erythrocytes in vitro was studied in 21 patients with immune hemolytic anemia. Simultaneous assessment of immunoglobulin and complement components on the patients' erythrocytes was performed. The patients were heterogeneous in relation to associated diseases, therapy, and duration of disease state; 15 were studied within 1 mo of diagnosis and 4 addi...

Sitosterolemia is an autosomal recessive disorder characterized by increased plant sterol levels, xanthomas, and accelerated atherosclerosis. Although it was originally reported in patients with normolipemic xanthomas, severe hypercholesterolemia have been reported in patients with sitosterolemia, especially in children. Sitosterolemia is caused by increased intestinal absorption and decreased ...

A 71-year-old woman came to the hospital because of generalized weakness, fatigue, and exertional dyspnea. She had a history of anemia, recurrent urinary tract infections, and hyperactive bladder. She had been taking nitrofurantoin for a urinary tract infection and phenazopyridine for dysuria, and she noticed that her urine was dark-colored. She was of northern European descent. She was unaware...

Pseudomonas aeruginosa, an opportunistic, but serious multidrug-resistant pathogen, secretes a ceramidase capable of cleaving the N-acyl linkage of ceramide to generate fatty acids and sphingosine. We previously reported that the secretion of P. aeruginosa ceramidase was induced by host-derived sphingolipids, through which phospholipase C-induced hemolysis was significantly enhanced. We herein ...

background: sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood ph in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (g6pd) deficiency. the aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and hematolog...

introduction autoimmune haemolytic anemia (aiha) is a complex process characterized by an immune reaction against red blood cell self-antigens. the analysis of specimens, drawn from patients with cold auto-immune hemolytic anemia is a difficult problem for automated hematology analyzer. this paper was written to alert technologists and pathologists to the presence of cold agglutinins and its ef...
