Enhanced Detection of Leishmania Parasites in Microscopic Images Using Machine Learning Models.

Cutaneous leishmaniasis is a parasitic disease that poses significant diagnostic challenges due to the variability of results and reliance on operator expertise. This study addresses the development of a system based on machine learning algorithms to detect spp. parasite in direct smear microscopy images, contributing to the diagnosis of cutaneous leishmaniasis.

Nasal Valve Considerations in Mohs Reconstruction.

Airway obstruction is a possible sequela following reconstruction of the nose after Mohs excision of skin cancers. While the principles and goals of tissue replacement after Mohs micrographic surgery are well-established, less attention has been paid to the evaluation of the nasal airway after reconstruction. Reconstructive planning begins with understanding the risk factors associated with the development of nasal valve compromise.

Assessing the Interactions between Snake Venom Metalloproteinases and Hydroxamate Inhibitors Using Kinetic and ITC Assays, Molecular Dynamics Simulations and MM/PBSA-Based Scoring Functions.

species are the main cause of snake bites in rural communities of tropical developing countries of Central and South America. Envenomation by snakes is characterized by prominent local inflammation, hemorrhage and necrosis as well as systemic hemostatic disturbances. These pathological effects are mainly caused by the major toxins of the viperidae venoms, the snake venom metalloproteinases (SVMPs).

Improved influenza A whole-genome sequencing protocol.

Influenza A virus poses significant public health challenges due to its high mutation rate and zoonotic potential. Whole-genome sequencing (WGS) is crucial for monitoring and characterizing these viruses. Oxford Nanopore Technologies (ONT) and Illumina next-generation sequencing platforms are commonly used, with ONT being advantageous for its long-read capabilities, portability, and unique ability to access raw data in real-time during sequencing, making it suitable for rapid outbreak responses.

Testing of Retail Cheese, Butter, Ice Cream, and Other Dairy Products for Highly Pathogenic Avian Influenza in the US.

The recent outbreak of highly pathogenic avian influenza (HPAI) in dairy cows has created public health concerns about the potential of consumers being exposed to live virus from commercial dairy products. Previous studies support that pasteurization effectively inactivates avian influenza in milk and an earlier retail milk survey showed viral RNA, but no live virus could be detected in the dairy products tested. Because of the variety of products and processing methods in which milk is used, additional product testing was conducted to determine if HPAI viral RNA could be detected in retail dairy samples, and for positive samples by quantitative real-time RT-PCR (qRT-PCR) further testing for the presence of live virus.
