Background: Alzheimer's disease (AD) is characterized- at both early and late stages- by neurovascular impairment. In AD, dysfunctional cerebral microvasculature is accompanied by an inflammatory response, contributing to Aβ and tau accumulation, brain cell stress and death, impaired clearance of metabolic waste, BBB permeability, and ultimately leading to neuronal demise and cognitive impairment. We previously showed that Aβ peptides induce mitochondrial dysregulation and caspase-mediated apoptosis in brain cells, including endothelial, glial, and smooth muscle cells.

Bovine trichomoniasis is a reproductive illness that affects cattle causing pyometra, early to mid-pregnancy miscarriages, and lower birth rates. is a flagellated protozoan which first discovered in France in 1888 and composts three phases during its lifecycle including trophozoite, cyst, and pseudocyst. In addition, several factors contributed to the prevalence of trichomoniasis and fall into three categories are management, cow, and bull-related factors.

The maintenance of intracellular and extracellular adenosine triphosphate (ATP) levels plays a pivotal role in cardiac function. In recent years, burgeoning attention has been directed towards ATP-induced cell death (AICD), revealing it as a distinct cellular demise pathway triggered by heightened extracellular ATP concentrations, distinguishing it from other forms of cell death such as apoptosis and necrosis. AICD is increasingly acknowledged as a critical mechanism mediating the pathogenesis and progression of various cardiovascular maladies, encompassing myocardial ischemia-reperfusion injury, sepsis-induced cardiomyopathy, hypertrophic cardiomyopathy, arrhythmia, and diabetic cardiomyopathy.

Background: In low- and middle-income countries, trauma is the leading cause of death among youth and it is also a major cause of disability. Globally, more than 1,600 children and adolescents below the age of 19-years die every day from preventable injuries. Traffic-related injuries, falls, sports-related injuries, assaults, burns, and drownings are the most commonly reported causes of traumatic mortality among children.

Background: Neuropathic pain (NP) constitutes a significant burden for individuals, manifesting as nociceptive anaphylaxis, hypersensitivity, and spontaneous pain. Previous research has suggested that the analgesic effects of NP are mediated by dopamine (DA) neurons in the ventral tegmental region (VTA) through projections to various brain regions. A decrease in VTA dopamine neurons following NP may contribute to prolonged pain.
