Hypertrophic cardiomyopathy (HCM) can involve the right ventricle (RV), although RV hypertrophy usually exists with left ventricular (LV) hypertrophy and the severity of hypertrophy is milder in the RV than in the LV. We report a case of isolated extreme RV hypertrophy with a maximum RV wall thickness of 40 mm. A 72-year-old man presented with an abnormal electrocardiogram and isolated hypertrophy of the RV apex was found on echocardiography. A diagnosis of HCM was made based on myocardial features on multiple imaging modalities such as the similar myocardial characteristics to LV hypertrophy and systolic thickening. The isolated hypertrophy of the RV apex exhibited partial calcification, which was surrounded by hypoperfused areas of the myocardium on multidetector computed tomography. < Patients with hypertrophic cardiomyopathy (HCM) are characterized by left ventricular hypertrophy unexplained by secondary causes, although right ventricular (RV) involvement can develop. We report a case of isolated extreme RV HCM with a maximum wall thickness of 40 mm accompanied by intramyocardial calcification, highlighting the importance of acknowledging the diverse phenotypes in HCM.>.

Extreme environments such as hyperarid, hypersaline, hyperthermal environments, and the deep sea harbor diverse microbial communities, which are specially adapted to extreme conditions and are known as extremophiles. These extremophilic organisms have developed unique survival strategies, making them ideal models for studying microbial diversity, evolution, and adaptation to adversity. They also play critical roles in biogeochemical cycles.

Microbial Volatile Organic Compounds (MVOCs) are diverse molecules produced by microorganisms, ranging from mere waste by-products to important signalling molecules. While the interest in MVOCs has been increasing steadily, there is a significant gap in our knowledge of MVOCs in extreme environments with e.g.

To propagate their genetic material, flowering plants rely on the production of large amounts of pollen grains that are capable of germinating on a compatible stigma. Pollen germination and pollen tube growth are thought to be extremely energy-demanding processes. This raises the question of whether mitochondria from pollen grains are specifically tuned to support this developmental process.

Proteases are hydrolases that act on peptide bonds, releasing amino acids and/or oligopeptides, and are involved in essential functions in all organisms. They represent an important segment of the global enzyme market, with applications in the food, leather, detergent, and pharmaceutical industries. Depending on their industrial use, proteases should exhibit high activity under extreme conditions, such as low temperatures, e.

The growing incidence of infections caused by antibiotic-resistant strains of pathogens is one of the key challenges of the 21 century. The development of novel technological platforms based on single-cell analysis of antibacterial activity at the whole-microbiome level enables the transition to massive screening of antimicrobial agents with various mechanisms of action. The microbiome of wild animals remains largely underinvestigated.
