Dermoscopy is a non-invasive tool which helps in the visualization of skin structures and patterns not visible to the naked eye. This study evaluates the effectiveness of dermoscopy in diagnosing primary syphilis, which typically presents as a painless ulcer at the site of inoculation. In this study, dermoscopic patterns such as vascular structures and background colour changes were analyzed in patients with confirmed primary syphilis.

Article Synopsis
  • The study aimed to genetically diagnose methicillin-resistant staphylococcus aureus (MRSA) from diabetic foot infections and test the effectiveness of reuterin in inhibiting its growth.
  • Conducted in Iraq, the research involved analyzing 62 samples from diabetic patients, confirming MRSA presence through genetic methods, and determining the inhibition levels of reuterin.
  • Results showed that reuterin effectively inhibited MRSA without harming human red blood cells, suggesting it as a viable natural antimicrobial option for treating diabetic foot wounds.

State Key Laboratory of Food Nutrition and Safety, Key Laboratory of Food Nutrition and Safety, Ministry of Education, College of Food Science and Engineering, Tianjin University of Science and Technology, No. 29, 13th Avenue, Tianjin Economy Technological Development Area, Tianjin 300457, China.

The study aimed to investigate the alleviation of an ethanol-induced gastric ulcer in mice by apolysaccharide (PSP) from purple sweet potato ( (L.) Lam) and explore the mechanism. The anti-ulcer activity was determined by histopathological evaluation, total gastric acidity, pepsin activity, gastric ulcer index and gastric ulcer inhibition rate.
