ATAK (Adrenaline, Takotsubo, anaphylaxis, and Kounis hypersensitivity-associated syndrome) following common cobra (Naja naja) bite: A case report from Sri Lanka.

A 68-year-old woman, after an Indian cobra (Naja naja) bite, developed anaphylaxis, Takotsubo cardiomyopathy, and Kounis syndrome. She was initially diagnosed with acute coronary syndrome after anaphylaxis due to exposure to cobra venom, indicating Kounis syndrome. The echocardiogram, electrocardiogram, and almost complete reversal of dyskinetic myocardium established Takotsubo cardiomyopathy.

Oxidative photocatalysis on membranes triggers non-canonical pyroptosis.

Intracellular membranes composing organelles of eukaryotes include membrane proteins playing crucial roles in physiological functions. However, a comprehensive understanding of the cellular responses triggered by intracellular membrane-focused oxidative stress remains elusive. Herein, we report an amphiphilic photocatalyst localised in intracellular membranes to damage membrane proteins oxidatively, resulting in non-canonical pyroptosis.

A peculiar presentation of tamponade: pericardial mesothelioma.

Pericardial mesothelioma (PM) is rare with only 200 cases recorded, and a post-mortem prevalence of <0.0022%. It is the third most common cardiac/pericardial tumour, behind angiosarcoma and rhabdomyosarcoma.

Stoichiometrically optimized e orbital occupancy of Ni-Co oxide catalysts for Li-air batteries.

Li-air battery (LAB) technology is making continuous progress toward its theoretical capacity, which is comparable to gasoline. However, the sluggish reaction at the cathode is still a challenge. We propose a simple strategy to optimize the surface e occupancy by adjusting the stoichiometric ratios of transition metal-based spinel structures through a controlled hydrothermal synthesis.

Single-Molecule Force Spectroscopy of Membrane Protein Folding.

Single-molecule force spectroscopy is a unique method that can probe the structural changes of single proteins at a high spatiotemporal resolution while mechanically manipulating them over a wide force range. Here, we review the current understanding of membrane protein folding learned by using the force spectroscopy approach. Membrane protein folding in lipid bilayers is one of the most complex biological processes in which diverse lipid molecules and chaperone proteins are intricately involved.
