Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.

The composition of the faecal microbial flora of milking cows on feeds containing urea as the sole or partial source of nitrogen

Agricultural and Food Science, 1980
Using a variety of culture media, counts of live bacteria in the faeces of milking cows on purified, protein-free feed in which urea was the only source of nitrogen (0-cows) and on urea-rich, low-protein feed (ULP-cows) were made. Samples were taken from

Evaluation of Laboratory‐Scale Composting Reactors to Simulate Compost Barn Bedding Dynamics

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT Efficient management of compost bedding is essential for sustainability and animal welfare in Compost Barns (CBs). This study evaluated laboratory‐scale bioreactors as tools to simulate CB composting dynamics, focusing on temperature control, aeration, and wood shaving supplementation. Three sequential experiments were conducted. Test 1 used a

Hidden Partners in Diversity: Acidobacteriota and Their Distribution in the Cape Floristic Region

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Acidobacteriota diversity and abundance investigated in nutrient‐poor fynbos soils of the Cape Floristic Region. Nanopore 16S rRNA sequencing of 26 soil samples from Jonkershoek and Kogelberg identified dominant and rare subdivisions, revealed distinct community compositions, and demonstrated correlations between subdivisions and soil properties ...

[A combination of ampicillin and sulbactam: effect on aerobic and anaerobic gram-negative bacteria].

Revista medica de Chile, 1991
The antibacterial activity of the association of ampicillin and sulbactam (2:1) upon strains of aerobic and anaerobic Gram negative agents was assayed. Inhibition of B-lactamases from intact and disrupted cells of some selected strains by sulbactam was also determined.

Integration of MALDI‐TOF MS and 16S rRNA Analysis for Identification of Plant‐Based Fermentation‐Associated Microbiota

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Plant‐based fermentation matrices significantly influence microbial diversity and species‐specific proteomic adaptations. The integration of MALDI‐TOF MS and 16S rRNA sequencing with physicochemical analyses allowed for a better understanding of the impact of specific fermentation products on differences in microbial diversity and spectral protein ...
