Bioanalytical methods evolve throughout clinical development timelines, resulting in the need for establishing equivalency or correlation between different methods to enable comparison of data across different studies. This is accomplished by the conduct of cross validations and correlative studies to compare and describe the relationship. The incurred sample reanalysis acceptance criterion seems to be adopted universally for cross validations and correlative studies; however, this does not identify any trends or biases between the two methods (datasets) being compared. Presented here are graphing approaches suitable for comparing two methods and describing equivalence or correlation. This article aims to generate awareness on graphing techniques that can be adopted during cross validations and correlative studies.

Motivation: Representation learning has revolutionized sequence-based prediction of protein function and subcellular localization. Protein networks are an important source of information complementary to sequences, but the use of protein networks has proven to be challenging in the context of machine learning, especially in a cross-species setting.
Results: We leveraged the STRING database of protein networks and orthology relations for 1,322 eukaryotes to generate network-based cross-species protein embeddings.

Background: Statin therapy lowers the risk of major adverse cardiovascular events (MACE) among people with HIV (PWH). Residual risk pathways contributing to excess MACE beyond low-density lipoprotein cholesterol (LDL-C) are not well understood. Our objective was to evaluate the association of statin responsive and other inflammatory and metabolic pathways to MACE in the Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE).

Importance: Long COVID (ie, post-COVID-19 condition) is a substantial public health concern, and its association with health-related social needs, such as food insecurity, remains poorly understood. Identifying modifiable risk factors like food insecurity and interventions like food assistance programs is critical for reducing the health burden of long COVID.
Objective: To investigate the association of food insecurity with long COVID and to assess the modifying factors of Supplemental Nutrition Assistance Program (SNAP) participation and employment status.

In vitro assessment of the inhibitory effect of antiplatelet drugs on platelet aggregation is frequently employed to guide personalized antiplatelet therapy in clinical practice. However, existing methods for detecting platelet aggregation rely heavily on high concentrations of exogenous agonists, which may obscure part of the inhibitory effect of antiplatelet drugs and lead to an underestimation of their effects. This study validates a novel analytical strategy for evaluating the effects of antiplatelet drugs by quantifying the microscopic three-dimensional morphological parameters of platelet aggregates formed through spontaneous aggregation on a glass surface.

Introduction And Hypothesis: To translate and perform cultural adaptation of the Pelvic Floor Dysfunction-SENTINEL (PFD-SENTINEL) screening tool into Turkish and to establish its reliability and validity for female athletes.
Methods: The study included 200 female athletes (mean age 22 ± 4 years). The translation of the PFD-SENTINEL, which comprised the symptoms related to PFD and item sections related to general risk factors and sports-related risk factors, was performed in accordance with international recommendations.
