Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Efeitos de indicadores e dias de coleta na digestibilidade dos nutrientes e nas estimativas do valor energético de alimentos para vacas alimentadas com diferentes fontes de proteína Comparison of internal markers and extent of total fecal collection to estimate nutrient digestibility and energy value of feeds on dairy cows fed different protein sources

Revista Brasileira de Zootecnia, 2006
Foram utilizadas 12 vacas da raça Holandesa, entre puras e mestiças, distribuídas em três quadrados latinos 4 x 4, organizados de acordo com os dias em lactação, com o objetivo de avaliar o efeito de dois períodos de coleta de fezes (dois ou seis dias ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Casein Supplementation Does Not Affect the Estimates of True Total Tract Digestibility of Phosphorus in Soybean Meal for Growing Pigs Determined by the Regression Method [PDF]

Asian-Australasian Journal of Animal Sciences, 2016
Forty-eight barrows with an average initial body weight of 25.5±0.3 kg were assigned to 6 dietary treatments arranged in a 3×2 factorial of 3 graded levels of P at 1.42, 2.07, or 2.72 g/kg, and 2 levels of casein at 0 or 50 g/kg to compare the estimates ...

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota-Associated Kynurenine Accumulation and Macrophage Remodeling. [PDF]

Adv Sci (Weinh)
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

Rapid regrowth and detection of microbial contaminants in equine fecal microbiome samples. [PDF]

PLoS ONE, 2017
Advances have been made to standardize 16S rRNA gene amplicon based studies for inter-study comparisons, yet there are many opportunities for systematic error that may render these comparisons improper and misleading.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Total fecal IgA levels increase and natural IgM antibodies decrease after gastric bypass surgery [PDF]

, 2022
Obesity is associated with low-grade inflammation and increased systemic oxidative stress. Roux-en-Y gastric bypass (RYGB) surgery is known to ameliorate the obesity-induced metabolic dysfunctions.
