Pharmaceuticals (Basel)

December 2023

Departamento de Farmacobiología, Cinvestav-Coapa, Czda. de los Tenorios 235, Col. Granjas-Coapa, Deleg. Tlalpan, Ciudad de México 14330, Mexico.

Article Synopsis
  • Purine nucleosides and nucleotides like ATP can affect cardiovascular responses, with adenosine-5'-(β-thio)-diphosphate (ADPβS) causing vasodilatation through purinergic P2Y receptors.
  • A study tested the specific P2Y receptor subtypes involved in blood pressure changes induced by ADPβS in male Wistar rats, using various antagonists and different experimental conditions.
  • Findings showed that initial decreases in diastolic blood pressure from ADPβS were linked to peripheral P2Y receptor activation, while later increases in systolic blood pressure also implicated multiple P2Y receptor types.

Article Synopsis
  • Signet ring cell carcinoma (SRCC) and diffuse type adenocarcinoma of the stomach and gastroesophageal junction have poor prognosis, and the impact of neoadjuvant chemotherapy (nCT) and chemoradiotherapy (nCRT) on patient outcomes is uncertain.
  • A study analyzed data from 2046 patients with diffuse type carcinoma, comparing those who received nCT versus those who underwent primary surgery, finding that nCT significantly reduced all-cause mortality both within 90 days and beyond after surgery.
  • The research concluded that nCT is associated with improved survival rates for patients with gastric and gastroesophageal junction cancers, including those with SRCC.

Clinical studies indicate that microvascular disease (MVD) affects bone microstructure and decreases bone strength in type 2 diabetes mellitus (T2D). Osteocytes are housed in small voids within the bone matrix and lacunae and act as sensors of mechanical forces in bone. These cells regulate osteoclastic bone resorption and osteoblastic bone formation as well as osteocytic perilacunar remodeling.

The striking link of Cushing's syndrome with the metabolic syndrome (MetS) and cardiovascular disease (CVD) suggests that long-term exposure to extremely high cortisol levels catalyzes cardiometabolic deterioration. However, it remained unclear whether the findings from the extreme glucocorticoid overabundance observed in Cushing's syndrome could be translated into more subtle variations in long-term glucocorticoid levels among the general population, for example, due to chronic stress. Here, we performed a systematic review (PROSPERO: CRD42023425541) of evidence regarding the role of subtle variations in long-term biological stress, measured as levels of scalp hair cortisol (HairF) and cortisone (HairE), in the context of MetS and CVD in adults.

A Multicenter Study Validates the WHO 2022 Classification for Conjunctival Melanocytic Intraepithelial Lesions With Clinical and Prognostic Relevance.

Lab Invest

January 2024

National Specialist Ophthalmic Pathology Service, Liverpool Clinical Laboratories, Liverpool University Hospitals NHS Foundation Trust, Liverpool, UK; Liverpool Ocular Oncology Research Group, Department of Molecular and Clinical Cancer Medicine, Institute of System Molecular and Integrative Biology, University of Liverpool, Liverpool, UK. Electronic address:

Several nomenclature and grading systems have been proposed for conjunctival melanocytic intraepithelial lesions (C-MIL). The fourth "WHO Classification of Eye Tumors" (WHO-EYE04) proposed a C-MIL classification, capturing the progression of noninvasive neoplastic melanocytes from low- to high-grade lesions, onto melanoma in situ (MIS), and then to invasive melanoma. This proposal was revised to the WHO-EYE05 C-MIL system, which simplified the high-grade C-MIL, whereby MIS was subsumed into high-grade C-MIL.
