New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2884-2894, August 2026.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Antigonococcal Activity and Cytotoxicity Screening of Three Ziziphus Species Indigenous to South Africa

Chemistry &Biodiversity, Volume 23, Issue 7, July 2026.
Ziziphus species in South Africa are widely used to treat gonorrhea; however, to this day, there has been no scientific validation of their ethnomedicinal use. This study tentatively identified phytol, betulin, and hexadecanoic acid to be linked to the observed antigonococcal activity.

Integrative Transcriptomic and Functional Analysis of PKMYT1 Reveals a Potential Therapeutic Target in Chronic Lymphocytic Leukemia

Hematological Oncology, Volume 44, Issue 4, July 2026.
ABSTRACT Chronic lymphocytic leukemia (CLL) is a clinically and molecularly heterogeneous disease. PKMYT1, a G2/M cell cycle kinase, has been implicated in tumor progression in several cancers, but its role in CLL remains unclear. We evaluated PKMYT1 expression in primary CLL samples and analyzed associations with cytogenetic features and clinical ...
