Cardiovascular effects of tirzepatide.

Tirzepatide is a first-in-class dual agonist at receptors for glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) for the treatment of T2D and obesity with unprecedented efficacy for glycaemic control and reductions in body weight as well as improvements in blood pressure and lipid profile compared with placebo and GLP-1 receptor agonists. To date, clinical trials of tirzepatide have fulfilled the requirement by regulatory authorities of demonstrated cardiovascular safety in high-risk patients. Whether cardiovascular benefits will be found with dual GLP-1/GIP receptor agonists remains uncertain, and the contribution of GIP receptor activation to cardiovascular risk has not been established.

Clinical Manifestations.

Background: Chronic depression impacts the ability to successfully manage one's health, yet mechanisms underlying this relationship are not fully understood. Cognitive dysfunction, or impairment, may result from persistent depression. We aimed to determine whether chronic depressive symptoms, leading to poor cognition, impacted self-management capacity among older adults with chronic conditions.

Clinical Manifestations.

Background: Most cognitive screening tests used in primary care to identify adults with cognitive impairment, including Alzheimer's disease and related dementias, have been limited in their diagnostic accuracy, especially in mild cases. Resultant false positives or false negatives (e.g.

Cardio-metabolic and cytoskeletal proteomic signatures differentiate stress hypersensitivity in dystrophin-deficient mdx mice.

Extreme heterogeneity exists in the hypersensitive stress response exhibited by the dystrophin-deficient mdx mouse model of Duchenne muscular dystrophy. Because stress hypersensitivity can impact dystrophic phenotypes, this research aimed to understand the peripheral pathways driving this inter-individual variability. Male and female mdx mice were phenotypically stratified into "stress-resistant" or "stress-sensitive" groups based on their response to two laboratory stressors.

Surface-enhanced Raman spectroscopy: a half-century historical perspective.

Surface-enhanced Raman spectroscopy (SERS) has evolved significantly over fifty years into a powerful analytical technique. This review aims to achieve five main goals. (1) Providing a comprehensive history of SERS's discovery, its experimental and theoretical foundations, its connections to advances in nanoscience and plasmonics, and highlighting collective contributions of key pioneers.
