Strain-induced instabilities of graphene under biaxial stress.

The mechanical properties of graphene are investigated using classical molecular dynamics simulations as a function of temperature T and external stress τ. The elastic response is characterized by calculating elastic constants via three complementary methods: (i) numerical derivatives of stress-strain curves, (ii) analysis of cell fluctuation correlations, and (iii) phonon dispersion analysis. Simulations were performed with two interatomic models: an empirical potential and a tight-binding electronic Hamiltonian.

Synchronous giant bilateral renal tumors as initial presentation of Von Hippel-Lindau disease: Sequential surgical management and transition to renal replacement therapy.

Synchronous bilateral renal cell carcinoma (RCC) is rare and often linked to hereditary syndromes such as Von Hippel-Lindau (VHL) disease. We present a 27-year-old male with acute appendicitis, whose CT incidentally revealed bilateral renal tumors and pancreatic cysts. Further evaluation identified cerebellar and retinal hemangioblastomas, confirming VHL.

High Prevalence, Genetic Diversity and Temporal Differentiation of Plasmodium vivax in a Remote Hard-to-Reach Community from the Peruvian Amazon Region.

Assessing parasite population genetic diversity and structure in remote areas is essential for understanding malaria transmission and guiding interventions toward elimination. This study monitored the genetic diversity and population structure of Plasmodium vivax as part of a longitudinal surveillance in Santa Emilia, a hard-to-reach community in Loreto, Peru. A total of 221 of 3,434 P.

A convective polymerase chain reaction (CPCR) coupled with NALF immunoassays as a rapid detection strategy for Listeria monocytogenes in pork meat.

Listeria monocytogenes is a foodborne pathogen that causes economic losses in the food industry and leads to illness. Developing more precise and expedited methodologies for pathogen detection is imperative for improving treatment efficacy and limiting the spread of diseases. This study developed a method leveraging a fast and effective polymerase chain reaction (CPCR) alongside nucleic acid lateral flow immunoassay cassettes (NALF1) to detect Listeria monocytogenes.
