The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

The Diverse Structure and Organization of U.S. Beef Cow-Calf Farms [PDF]

open access: yes
Beef cow-calf production in the United States is widespread, occurring in every State. Nearly 765,000 farms, about 35 percent of the 2.2 million farms in the United States, had a beef cow inventory in 2007. Most of these were small, part-time operations.

μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]

open access: yes, 2006
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

SALT OVERLY SENSITIVE 1 Na+/H+ Exchanger Operates in Mature Root Zone and Is a Major Contributor to Root Na+ Exclusion During Shoot‐to‐Root Na+ Recirculation

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1650-1660, March 2026.
ABSTRACT The Na+/H+ antiporter SALT OVERLY SENSITIVE 1 (SOS1) is a key component of Na+ exclusion and plant salt tolerance. Although previous studies have suggested that SOS1 functions in both the root apex and mature root zone, their contributions remain unclear due to limited methodological resolution and originated mostly from transcriptional ...

At‐Home Early Diagnosis of Mastitis: Calibration‐Free Analysis of Sodium to Potassium Ratio in Breast Milk

open access: yesAdvanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
MAMAWEL is introduced as the first calibration‐free potentiometric sensor for at‐home mastitis diagnosis. By measuring the sodium‐to‐potassium ratio in breast milk, the device reliably differentiates between healthy and mastitis‐affected samples with less than 10% error.

Clinical significance and immune microenvironment association of cuproptosis‐related genes in pan‐cancer

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 539-555, 1 February 2026.
Abstract Recent studies highlight the important roles of cuproptosis in cancer cells. However, the roles of the cuproptosis‐related genes (CRGs) in different cancers are still not fully understood. Comprehensive analysis was performed using open‐source bioinformatic platforms to disclose the expression profiles, prognostic significance, genomic and ...
