Periodontal regeneration is the anticipated result of periodontal tissue therapy. Of the many scaffold materials utilized, collagen has been shown to possess characteristics that strongly promote the periodontal regeneration process. Gourami (Osphronemusgoramy) scales can be utilized as an alternative source of collagen due to their abundant availability, the absence of risk of zoonosis, and lack of religious strictures against their use. ⋯ The pore sizes ofcollagen extracted from gouramy scalesare suitable for use as scaffold. FTIR analysis indicated that this collagen possessed a triple helix structure. Collagen extracted from gourami scales was completely degraded within seven days when treated with 0.6 g/mL collagenase solution.

Coronary artery bypass surgery without blood transfusion; is it possible?
Coronary artery bypass surgery is the most commonly performed cardiac operation and approximately 40-70% of patients require a blood transfusion despite improvements in cardiac surgical techniques. Some preventive perfusion methods to avoid transfusions are described, such as acute normovolemic hemodilution, retrograde autologous priming, and usage of integrated arterial filter oxygenator. ⋯ Triple combination technique is safe and cost-effective in coronary artery bypass surgery. We think that most of the patients could be operated without blood transfusion with this technique.

Odontogenic cysts develop from the epithelium of dental structures and generally grow slowly. In children and adolescents, cysts usually grow faster than adults and require much knowledge for diagnoses and treatments. ⋯ When odontogenic cysts seen in children and adolescents are examined with cone-beam computed tomography, the radicular cyst was the most common form and was predominated in the 13-18 years age group and in boys. Differences in terms of scalloped borders, lesion shape, tooth displacement, root resorption, and association with unerupted teeth were noticed. The knowledge of the distribution and properties of odontogenic cysts in pediatric patients will help diagnose the lesions during clinical and radiological examinations and make appropriate treatment planning.

Pregnancy is a period of heightened calcium demand necessary for the optimum growth and development of the fetus and placenta. Women with low calcium intake may manifest with hypocalcemia in pregnancy. ⋯ Hypocalcemia in pregnancy is common in our environment and it is associated with anemia in pregnancy, anorexia, and primigravidity while attainment of at least basic education is protective. We recommend routine calcium supplementation in pregnancy and preconception period.

Nigeria ranks third among the countries with the highest HIV/AIDS burden in the world, next only to India and South Africa. The North-Central zone which Kwara State belongs to has the highest concentration of HIV prevalence rate of 7.5%, while the North-Western zone recorded the lowest prevalence of 2.1%; Kwara state has a prevalence rate of 2.2%. ⋯ HIV is a chronic disease with heavy burden on both patients and health facility rendering services for the care of these patients. A good proportion of respondents interviewed adopted varying coping strategies. Sustained social and psychological support will improve further the coping strategies of living with HIV.
