Application of Hybridization Chain Reaction/CRISPR-Cas12a for the Detection of SARS-CoV-2 Infection.

Globally, the emergence of the coronavirus disease (COVID-19) has had a significant impact on life. The need for ongoing SARS-CoV-2 screening employing inexpensive and quick diagnostic approaches is undeniable, given the ongoing pandemic and variations in vaccine administration in resource-constrained regions. This study presents results as proof of concept to use hybridization chain reaction (HCR) and clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a complex for detecting SARS-CoV-2.

Expression of the Fab enzymes (Fab I and Fab Z) from after exposure to plant extracts and drugs screening.

The emergence and spread of drug resistance of the malaria parasite to the main treatment emphasize the need to develop new antimalarial drugs. In this context, the fatty acid biosynthesis (FAS_II) pathway of the malaria parasite is one of the ideal targets due to its crucial role in parasite survival. In this study, we report the expression and the affinity binding of Fab_I and Fab_Z after exposure to the parasite with different extracts of the .

Evaluation of lethality and cytotoxic effects induced by (large brown spitting cobra) venom and the envenomation-neutralizing efficacy of selected commercial antivenoms in Kenya.

Neutralization of lethality in mice model at the preclinical level has been established by the World Health Organization as the gold standard for the evaluation of antivenom efficacy. The assessment of the neutralization profiles of antivenoms helps to discern the efficacy or otherwise of these antivenoms at neutralizing the toxic effects induced by medically significant snake venoms. However, for many antivenoms, information on their preclinical efficacy remains limited.

Development and Characterization of Anti- Three-Finger Toxins (3FTxs)-Specific Monoclonal Antibodies and Evaluation of Their In Vitro Inhibition Activity.

Antivenom immunotherapy is the mainstay of treatment for snakebite envenoming. Most parts of the world affected by snakebite envenoming depend on broad-spectrum polyspecific antivenoms that are known to contain a low content of case-specific efficacious immunoglobulins. Thus, advances in toxin-specific antibodies production hold much promise in future therapeutic strategies of snakebite envenoming.

The prevalence of endometriosis among African-American and African-indigenous women.

Endometriosis is gynaecological disorder, characterized by the growth of endometrial tissue outside the uterine cavity. It is the most common cause of pelvic pain and occurs in 20-25% of women with infertility. Although Sampson first described endometriosis in 1927, studies on the prevalence of endometriosis among African women are still lacking.
