Diethylene Glycol‐Linked Ring‐Fused Bis‐Azoles: Target‐Oriented Synthesis, In Silico Screening, and Antitumor Activity

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
A series of diethylene glycol‐linked cyclic derivatives with diversity in the heterocyclic motif have been synthesized and screened for antitumor activity. Two bis‐thiazolo[3,2‐a]pyrimidinone derivatives displayed moderate cytotoxicity, high selectivity against hepatocellular carcinoma cells, promising VEGFR2, and remarkable FGFR2 inhibitory activities

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, Volume 14, Issue 7, Page 2252-2261, October 2026.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Co‐Culture of Mammalian Cells and Photosynthetic Microorganisms for Oxygen Supply in Engineered Tissues

Cell Proliferation, Volume 59, Issue 10, October 2026.
Continuous 28‐day light exposure alters behaviours of articular cartilage progenitor cells (ACPCs) and mesenchymal stromal cells (MSCs). Co‐culture with Leptolyngbya and Synechococcus does not adversely affect the chondrogenic capacity of ACPCs over a 28‐day period, in contrast to co‐culture with Chlorella.

Complications and outcomes of standing flank versus ventral midline laparotomy for equine nephrosplenic entrapment

Equine Veterinary Education, Volume 38, Issue 10, Page e736-e743, October 2026.
Summary Background Nephrosplenic entrapment (NSE) is a common surgical colic in horses. Ventral midline laparotomy (VML) under general anaesthesia (GA) is the standard approach, whereas standing flank laparotomy (SFL) is an alternative approach for surgical correction. However, direct comparisons between these approaches are lacking.
