Microbial Etiology and Antimicrobial Resistance in Pneumonia Among Hospitalized Patients in Kazakhstan: A Systematic Review and Single‐Arm Meta‐Analysis of Prevalence Data

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Pneumonia is an inflammatory condition of the lower respiratory tract, commonly caused by infection and associated with substantial morbidity and healthcare utilization. The burden of pneumonia on healthcare is exacerbated by limited data on pathogenic causes and associated antimicrobial resistance (AMR). Here, we conducted

Method Development for the Analysis of Carbonaceous Chondrites by Laser Desorption/Ionization and Secondary Ion Time‐of‐Flight Mass Spectrometry

Journal of Mass Spectrometry, Volume 61, Issue 4, April 2026.
ABSTRACT This study focuses on the development of a laser desorption/ionization mass spectrometric method for analyzing carbonaceous chondrites, meteorites that may hold clues to the origin of life. Since carbonaceous chondrites are only available in small quantities, we initially designed an artificial meteorite material (the mineral forsterite) doped

Tailoring Electronic Properties of Precision Graphene Nanoribbons via Nanopore Engineering

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Novel porous graphene nanoribbons incorporating [18]annulene nanopores, together with a nonporous GNR of identical width, have been synthesized. Spectroscopic and theoretical analyses reveal that nanopore incorporation effectively tunes their electronic properties by enlarging the bandgap, reducing charge‐carrier mobility, and modulating exciton ...

Nanobody‐Mediated c‐MYC Degradation Inhibits Tumor Cell Progression

MedComm, Volume 7, Issue 4, April 2026.
A cell‐permeable nanobody strategy was developed to target the intrinsically disordered oncoprotein c‐MYC. A synthetic nanobody, M4, binds the central PEST region of c‐MYC (241–263) and promotes c‐MYC degradation by enhancing Thr58 phosphorylation. Conjugation of M4 to a cell‐penetrating peptide (CPP) generates CPM4, which efficiently accumulates in ...

First Detection of Lactococcus formosensis subsp. formosensis in Rainbow Trout (Oncorhynchus mykiss) in Europe

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis are etiological agents of piscine lactococcosis, a disease reported in Italy since the early 1990s and linked to significant aquaculture losses. To the best of our knowledge, this study reports the first detection of L. formosensis subsp. formosensis in farmed rainbow trout (
