This case report shows unique aneurysm at the left ventricular apex associated with a double-chambered left ventricle (DCLV) in asymptomatic 69-year-old female. The aneurysm was located at the apex of an accessory chamber, which was formed by hypertrophied muscle band and the interventricular septum, along with a pronounced jet flow directed towards the apex aneurysm. These finding suggests that the obstruction at the base of the accessory chamber caused a pressure overload at the apex, ultimately leading to the development of the aneurysm. To best of our knowledge, this is the first case to prove the underlying cause of aneurysm formation in DCLV.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) are resistant to nearly all β-lactam antibiotics under standard testing conditions. However, a novel phenotype exists wherein certain MRSA strains exhibit β-lactam susceptibility in the presence of bicarbonate (termed 'NaHCO3-responsive'), an abundant ion in mammalian tissues and blood. This suggests that specific MRSA infections may be treatable by β-lactams.

The study of primate auditory morphology is a significant area of interest for comparative anatomists, given the phylogenetic relationships that link primate hearing and the morphology of these auditory structures. Extensive literature addresses the form-to-function relationship of the auditory system (outer, middle, and inner ear) in primates and, by extension, provides insight into the auditory system of extinct primates and even modern humans. We add to this literature by describing the ontogenetic trajectory of the middle ear cavity and ossicular chain (malleus, incus, and stapes) due to their critical role in relaying auditory stimuli for interpretation.

Automatic and precise fluid manipulation is essential in microfluidic applications. Microfluidic metering, in particular, plays a critical role in achieving the multiplexity of assays, reaction consistency, quantitative analysis, and the scalability of microfluidic operations. However, existing fluid metering techniques often face limitations, such as high complexity, high cost, reliance on external accessories, and lack of precision, which have restricted their use in multiplexed and quantitative analysis, especially in portable applications.
