Singapore's COVID-19 Genomic Surveillance Programme: Strategies and Insights From a Pandemic Year.

Background: During the COVID-19 pandemic, genomic surveillance was crucial for monitoring virus spread and identifying variants. Effective surveillance helped understand transmission dynamics. Singapore had success in combating COVID-19 through its surveillance programmes.

Electrochemical Investigation of the Oxidation of Phenolic Compounds Using Hypervalent Iodine Oxidants.

The chemical oxidation of simple phenolic compounds by the hypervalent iodine reagent [hydroxy(tosyloxy)iodo]benzene (HTIB) was investigated using electrochemical and spectroscopic methods. HTIB oxidized phenol and benzenediol isomers hydroquinone (HQ), catechol, and resorcinol to form various quinone structures. HQ and catechol, two compounds that show reversible electrochemical behavior, exhibited simple oxidative chemistry to their respective quinone structures that could be electrochemically reduced at a glassy carbon electrode.

Trend of soil salinization in Africa and implications for agro-chemical use in semi-arid croplands.

Soil salinization is a gradual degradation process that begins as a minor problem and grows to become a significant economic loss if no control action is taken. It progressively alters the soil environment which eventually negatively affects plants and organism that were not originally adapted for saline conditions. Soil salinization arises from diverse sources such as side-effects of long-term use of agro-chemicals, saline parent rocks, periodic inundation of soil with saline water, etc.

Enhancing point-of-care ultrasound (POCUS) utilization in primary care: A thyroid POCUS training course for internal medicine residents.

Background: POCUS is valuable in primary care, yet outpatient-specific point-of-care ultrasound (POCUS) curriculum integration into internal medicine (IM) residency is limited. We addressed this gap by developing a thyroid POCUS workshop for IM residents.

Aim: Develop and implement an educational curriculum to integrate thyroid POCUS into an IM residency program and evaluate the impact on resident knowledge, perceived skills, and attitudes.

A drug repurposing approach of Atorvastatin calcium for its antiproliferative activity for effective treatment of breast cancer: and assessment.

Breast cancer, the most common cancer among women, caused over 500,000 deaths in 2020. Conventional treatments are expensive and have severe side effects. Drug repurposing is a novel approach aiming to reposition clinically approved non-cancer drugs into newer cancer treatments.
