Dose‐Dependent Effects of Catecholaminergic Modulation on Interference Control: Role of Baseline GABA and Glx in Cortico‐Subcortical Networks

open access: yesHuman Brain Mapping, Volume 46, Issue 15, October 15, 2025.
We found medium methylphenidate doses (0.5 mg/kg) to be more effective than low doses (0.25 mg/kg) at reducing subliminal interference effects, with higher striatal GABA+ levels leading to better interference control at low doses, while lower ACC GABA+ and GABA+/Glx levels led to better interference control at medium doses.

Analysis of lactase processing in rabbit

open access: yesFEBS Letters, 1993
The proteolytic processing of rabbit intestinal lactase‐phlorizin‐hydrolase (LPH) was studied by pulse‐chase and continuous labeling experiments in organ culture from 15‐day‐old rabbits in the presence of glycosylation and processing inhibitors. Monensin and brefeldin A inhibited the two proteolytic cleavages of the precursor indicating that they are ...

Monolithic Biohybrid Flexure Mechanism Actuated by Bioengineered Skeletal Muscle Tissue

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 10, October 2025.
A scalable, monolithic biohybrid flexure mechanism is presented, integrating engineered skeletal muscle tissue with a soft, biocompatible, hollow silicone cylinder featuring dual pillars. Muscle contraction induces bending motion upon electrical stimulation, with performance governed by the structure's flexural rigidity.

Lactase persistence and milk consumption in Europe: an interdisciplinary approach involving genetics and archaeology

open access: yesDocumenta Praehistorica, 2013
The ability to digest milk during adulthood (lactase persistence) is a genetically determined trait present only in humans. Its origin and diffusion are correlated with the development of pastoralism and the consumption of fresh milk.

Investigating the Antioxidative and Antihypertensive Properties of Milk‐Derived Bioactive Peptides Fermented by Lactic Acid Bacteria

open access: yesFood Safety and Health, Volume 3, Issue 4, Page 598-612, October 2025.
This study investigated various properties of milk‐derived bioactive peptides fermented using different strains of Lactobacillus and Pediococcus species. Results revealed that microbial fermentation of cow milk enhanced peptide production, leading to improved ACE‐inhibition and antioxidant properties, thereby making fermented milk a valuable source of ...

Excellent agreement between genetic and hydrogen breath tests for lactase deficiency and the role of extended symptom assessment [PDF]

open access: yes, 2010
Clinical manifestations of lactase (LCT) deficiency include intestinal and extra-intestinal symptoms. Lactose hydrogen breath test (H2-BT) is considered the gold standard to evaluate LCT deficiency (LD).

In Vitro Characterization of Biodegradable Polyurethane Foams With Facile Gelatin Modification for Traumatic Wound Hemostasis and Regeneration

open access: yesJournal of Biomedical Materials Research Part A, Volume 113, Issue 10, October 2025.
ABSTRACT Polyurethane (PUr) foams are widely explored for embolic, hemostatic, and tissue engineering applications. Their tunable pore structure, mechanical properties, and degradation rates make PUr foams ideal scaffolds for thrombus formation and cell infiltration.

The Effects of Exogenous Lactase on Improving Gastrointestinal Symp-toms in Patients with Lactose Intolerance

open access: yesمجله دانشکده پزشکی اصفهان, 2011
Background: Lactose intolerance is common in Asian population. Enzyme replacement therapy facilitates consumption of milk and dairy products for patients with lactose intolerance. Clinical evidence in our clinics indicates a nonhomogeneity in improvement

Polymorphism in the oxytocin promoter region in patients with lactase non-persistence is not related to symptoms

open access: yesBMC Gastroenterology, 2009
Background Oxytocin and the oxytocin receptor have been demonstrated in the gastrointestinal (GI) tract and have been shown to exert physiological effects on gut motility. The role for oxytocin in the pathophysiology of GI complaints is unknown.
