Restructuring of Femoral Cortical Bone During Growth and Locomotor Development of Wild Chimpanzees (Pan troglodytes verus).

Objective: Chimpanzees are altricial in terms of their locomotor development and transition from being carried to engaging in suspensory and arboreal locomotor behaviors to eventually relying on terrestrial quadrupedalism as their main form of locomotion. Here, we consider the mechanical implications of femoral cortical bone restructuring during growth and locomotor development in wild chimpanzees.

Materials And Methods: Cortical bone structure was examined in an ontogenetic sample of wild chimpanzees from a single subspecies (P.

Gammaherpesvirus Infection Stimulates Lung Tumor-Promoting Inflammation.

Lung tumor-promoting environmental exposures and γherpesvirus infections are associated with Type 17 inflammation. To test the effect of γherpesvirus infection in promoting lung tumorigenesis, we infected mutant K-Ras-expressing (K-Ras) mice with the murine γherpesvirus MHV68 via oropharyngeal aspiration. After 7 weeks, the infected mice displayed a more than 2-fold increase in lung tumors relative to their K-Ras uninfected littermates.

Multi-organ Thromboembolic Crisis: A Case Report of Concomitant Stroke, Myocardial Infarction, and Pulmonary Embolism.

Management of acute coronary syndrome (ACS), cerebrovascular accident (CVA), and pulmonary embolism (PE) necessitates prompt intervention, as delayed treatment may lead to severe consequences. Each of these conditions presents significant challenges and carries a high risk of morbidity and mortality. We present the case of an 86-year-old female with a history of stage 4 urothelial carcinoma metastasized to the lungs, who presented to the emergency department (ED) with acute ischemic stroke (AIS), ST-segment elevation myocardial infarction (STEMI), and bilateral PE.

Metabolic theory of preeclampsia: implications for maternal cardiovascular health.

Preeclampsia (PE) is a multisystemic disorder of pregnancy that not only causes perinatal mortality and morbidity but also has a long-term toll on the maternal and fetal cardiovascular system. Women diagnosed with PE are at greater risk for the subsequent development of hypertension, ischemic heart disease, cardiomyopathy, cerebral edema, seizures, and end-stage renal disease. Although PE is considered heterogeneous, inefficient extravillous trophoblast (EVT) migration leading to deficient spiral artery remodeling and increased uteroplacental vascular resistance is the likely initiation of the disease.
