Spatial‐Scale Evolutionary Bias Sheds Light on the Latitudinal Diversity Gradient

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using Escherichia coli as a model species, our experimental findings reveal that populations in high‐fitness‐gain geographic regions undergo rapid expansion, competitively excluding populations from low‐fitness‐gain regions. This results in adaptive evolution that is biased toward areas with higher fitness potential.

The gut microbiome organ

iMeta, Volume 5, Issue 4, August 2026.
The gut microbiome can be conceptualized as a distributed organ‐like functional system with spatially structured organization, broad biochemical capacity, and continuous bidirectional communication with the host. By transforming dietary, host‐derived, and environmental substrates into bioactive metabolites with endocrine‐like, immunomodulatory, and ...

The Use of Purple Eggplant Fruit Calyx Stem (Solanum melongena L.) as an Alternative Source of Lactase-Producing Lactic Acid Bacteria

Biotropika: Journal of Tropical Biology
Lactose intolerance is a condition where the body cannot digest lactose due to a deficiency of the lactase enzyme in the digestive system, leading to various health issues and indirectly increasing the risk of stunting.

Genetics of lactase deficiency in Russia

Problems of Nutrition
The ability to digest lactose in adulthood is caused by a genetic mutation that emerged following the domestication of cattle approximately 10 000 years ago. However, many adults retain primary lactase deficiency - the ancestral phenotype characterized by a decline in lactase enzyme activity after weaning.

Long‐term outcomes of gastric bypass surgery in two Lusitano foals: Contemporary evidence for surgical decision‐making

Equine Veterinary Education, Volume 38, Issue 8, Page e509-e515, August 2026.
Summary Gastric outflow obstruction (GOO) occasionally requires surgical intervention in foals when medical management fails. Current literature lacks consensus on several surgical decisions, with most comprehensive reports dating back over a decade. Critical aspects—including jejunal loop orientation and necessity of jejunojejunostomy—remain debated ...

Lactase deficiency, omitted clinical problem [PDF]

, 1996
Prikazana je ukratko etiologija primarnog i osobito sekundarnog deficita laktaze kao uzroka intolerancije laktoze. Mogući uzroci sekundarne hipolaktacije i eventualno moguće rijetke alaktazije u našim su uvjetima češći: kronični alkoholizam, akutni i ...

Features of endocrine status in obese children and polymorphisms of the lactase gene

Zdorovʹe Rebenka, 2017
Background. Obesity is an imbalance of immunocytokine and neuroendocrine regulation of energy metabolism with excessive accumulation of adipose tissue in the body accompanied by the formation of a chronic proinflammatory immune response associated with ...

Chronic, but not acute, treatment with GLP‐2 and GIP in combination increases glucose absorption in the isolated vascularly perfused rat intestine

Physiological Reports, Volume 14, Issue 16, August 2026.
Chronic GLP‐2 + GIP treatment increases glucose absorption. Abstract The gut hormones, glucagon‐like peptide‐2 (GLP‐2) and glucose‐dependent insulinotropic polypeptide (GIP), may be important regulators of intestinal nutrient absorption. Using the isolated vascularly perfused rat intestine of male rats, we investigated the chronic and subacute ...

Relation of the disaccharidases in the small intestine of the rat to the degree of experimentally induced iron-deficiency anemia

Brazilian Journal of Medical and Biological Research, 2000
Hypolactasia associated with severe iron-deficiency anemia has been reported in several studies. The objective of the present study was to determine whether hypolactasia is associated with the degree and duration of iron-deficiency anemia.

Genetic Evidence From Linkage Disequilibrium Score Regression and Mendelian Randomization Links Cheese Intake to Cognitive Function

Food Frontiers, Volume 7, Issue 4, July 2026.
Cheese intake emerged as the strongest beneficial dietary factor for cognitive and mental health traits, supported by LDSC and two‐sample MR analyses. eQTL‐mapped genes linked to cheese‐associated variants converged on PPI and enrichment pathways involving cognition, synaptic function, and brain‐relevant biological processes.
