Tuberculosis, one of the most frequent infectious diseases, is caused by a mycobacterium tuberculosis bacteria and it infects several hundred million people each year, results in several million deaths annually. Because there is development of antibiotic resistance, the disease becomes incurable. So, in the absence of effective and potent drug with minimal resistance problems, the mortality rate increases annually. In this computational investigation, we performed In-silico ADME, bioactivity and toxicity parameters calculation of some selected anti-tuberculosis agents. To design a new molecule having good pharmacological profile, this study will provide the lead information.Key Words: Tuberculosis (TB), Bacillus Calmette-Guerin vaccine, TPSA, In Silico toxicity

Background: Wound healing is a complex process necessary for repairing damaged tissues and preventing infection. Selenium nanoparticles (Se NPs) were known due to their antioxidant and antimicrobial effects, also niacin has angiogenesis and antioxidant effects that are important in wound healing. Objective: The present study was conducted to investigate the effect of Se NPs and niacin in reducing and accelerating the wound healing time in mice. Methods: A simple wet chemical method has been modified to synthesize Se NPs in order to investigate their effect and niacin on reducing the wound healing in 80 adult female albino mice (250 mm2 full thickness open excision wound) that were divided into eight groups (10 mice/each). After 30-days, the mice were sacrificed, blood and tissue samples were taken for analysis. Results: The results showed that the percentage of wound area had been significantly reduced in Se NPs and niacin treated groups compared to the positive control. The level of Vascular Endothelial cell Growth Factor and Collagenase I in Se NPs and niacin groups significantly exceed those of other groups while Nitric Oxide (NO) was significantly decreased in treated groups. Liver and kidney functions showed the lower toxicity effect of Se NPs and niacin. Skin tissue showed the wound healing effect of Se NPs and niacin by regenerating skin layer compared to the positive group. Conclusion: Se NPs and niacin play an important role in accelerating and reducing the time of wound healing while they were antagonistic to each other.

Multibacillary Leprosy

BACKGROUND Leprosy contacts are sensitive indicator of the magnitude of severity, and a high risk for infection and disease, especially if the individuals are exposed to the bacillus with multibacillary cases, which reinforces the need for chemoprophylactic measures, such as the use single-dose rifampicin (SDR) combined with BCG vaccine. OBJECTIVE Our study will analyze the serological response of anti-NDO-LID, HO-1/HMOX and serum IFN-γ concentration as a prophylactic measure after the use of single-dose rifampicin (SDR) combined with the Bacillus Calmette-Guérin vaccine (BCG) among multibacillary leprosy household contacts. METHODS Intervention study based on a prospective cohort of household contacts of new cases of multibacillary leprosy diagnosed and registered in the Information System on Diseases of Compulsory Declaration (SINAN – Sistema de Informação de Agravos de Notificação) and residents in the municipalities of Cuiabá and Cáceres, Mato Grosso, in the years 2019 and 2020. Contacts with no signs and symptoms compatible with the disease of the intervention group will receive single-dose rifampicin (SDR) combined with BCG vaccine and will be compared to the control group. The follow-up of the cohort will last 12 months. The analyses of the anti-NDO-LID, HO-1/HMOX and serum concentration of IFN-γ tests as immunological markers before, 6 and 12 months after the intervention will be conducted in a reference laboratory (FIOCRUZ). RESULTS The study is still recruiting participants and is expected to be completed in September 2020. CONCLUSIONS Our study seeks to analyze the response of anti-NDO-LID, HO-1/HMOX tests and serum IFN-γ concentration as a prophylactic measure after the use of single-dose rifampicin (SDR) combined with the Bacillus Calmette-Guérin vaccine (BCG) in home contacts of multibacillary leprosy cases.
