The Mercury (II) ion (Hg²⁺) is a toxic heavy metal that threatens biological systems by inducing oxidative stress and disrupting the redox balance. Biothiols such as cysteine (Cys), homocysteine (Hcy), and glutathione (GSH) are critical in maintaining redox homeostasis and are implicated in numerous physiological and pathological processes. Understanding the complex interactions between Hg²⁺ and biothiols requires molecular tools capable of simultaneous detection.

Although DNA methyltransferase 1 (DNMT1) and RNA editor ADAR triplications exist in Down syndrome (DS), their specific roles remain unclear. DNMT methylates DNA, yielding S-adenosine homocysteine (SAH), subsequently converted to homocysteine (Hcy) and adenosine by S-adenosine homocysteine (Hcy) hydrolase (SAHH). ADAR converts adenosine to inosine and uric acid.

An 86-year-old male patient developed paresthesia in both hands, and six months later, pancytopenia was noted. He was diagnosed with myelodysplastic syndrome following bone marrow aspiration. Despite high serum vitamin B12 level, elevated level of serum homocysteine, positive anti-intrinsic factor antibody, and T-weighted hyperintense lesions on spinal cord MRI led to a diagnosis of subacute combined degeneration of the spinal cord.

This review aims to summarize current knowledge and highlight recent findings on the association between cryptogenic stroke (CS) and patent foramen ovale (PFO). By presenting sometimes conflicting data, the review underscores the necessity for further research to clarify the complex mechanisms behind PFO-related CS and optimize its management. Results from research identifies specific conditions and scores, such as the risk of paradoxical embolism (RoPE) score, that help assess the likelihood of PFO-related cryptogenic stroke and guide treatment decisions.

Background: Tai Chi is a low-impact form of exercise that involves a series of slow movements that flow together. Increased plasma homocysteine(Hcy) levels are associated with an increased risk of cardiovascular diseases and may be reduced by exercise. This study aimed to compare plasma Hcy levels and the risk of hyperhomocysteinemia in 1,176 adults with and without Tai Chi exercises.
