Assessment of tuberculosis drug efficacy using preclinical animal models and in vitro predictive techniques.

Tuberculosis (TB) killed approximately 1.3 million people in 2022 and remains a leading cause of death from the bacteria Mycobacterium tuberculosis (M.tb); this number of deaths was surpassed only by COVID-19, caused by the SARS-CoV-2 virus.

Disparities in Triple Negative Breast Cancer Among Hispanic Population Living in Latin America Versus the United States.

Introduction: Triple-negative breast cancer (TNBC) has a prevalence of 12%-24% in the Hispanic population. Previous research has demonstrated that disparities in healthcare access significantly influence patient outcomes. We aimed to compare the clinicopathological characteristics and outcomes of Hispanic females with TNBC living in Latin America (HPLA) to the Hispanic population in the United States (HPUS).

Biopolymeric Inhalable Dry Powders for Pulmonary Drug Delivery.

Natural and synthetic biopolymers are gaining popularity in the development of inhaled drug formulations. Their highly tunable properties and ability to sustain drug release allow for the incorporation of attributes not achieved in dry powder inhaler formulations composed only of micronized drugs, standard excipients, and/or carriers. There are multiple physiological barriers to the penetration of inhaled drugs to the epithelial surface, such as the periciliary layer mucus mesh, pulmonary macrophages, and inflammation and mucus compositional changes resulting from respiratory diseases.

Effects of cladribine on intrathecal and peripheral B and plasma cells.

Introduction: Cladribine is a deoxyadenosine analogue that can penetrate the blood-brain barrier. It is used to treat multiple sclerosis (MS). However, the mechanistic understanding of the effect of this highly effective therapy on B cells and plasma cells in the central nervous system compartment is limited.

Specificity of 2 peripartum blood markers for early-lactation acute uterine inflammation in pasture-fed, seasonal-calving dairy cows.

A delayed recovery of the reproductive tract from natural inflammatory processes associated with postpartum involution will compromise further reproductive function. Following a literature review, we selected serum amyloid A (SAA) and α1-acid glycoprotein (α1-AGP) to assess as potential circulating markers of acute uterine inflammation, as concentrations of these 2 acute phase proteins were reported to be elevated early postpartum in dairy cows with active uterine infection. Convenience serum samples from an induced model of uterine infection were used to measure concentrations of these markers.
