High-resolution Manometry Findings in Patients After Sclerotherapy for Esophageal Varices [PDF]

, 2016
Background/Aims Endoscopic therapy for esophageal varices may lead to esophageal dysmotility. High-resolution manometry is probably the more adequate tool to measure esophageal motility in these patients.

Effects of visual blur on microsaccades during visual exploration

Journal of Eye Movement Research, 2019
Microsaccades shift the image on the fovea and counteract visual fading. They also serve as an optimal sampling strategy while viewing complex visual scenes. Microsaccade production relies on the amount of retinal error or acuity demand of a visual task.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Reduced glutathione and cysteine hydrochloride on crossbred bull semen [PDF]

, 2012
Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Differential Gastric Motility, Gut Hormone, and Appetite Changes Following A Mixed Meal in People With Obesity and Healthy Controls

Introduction Understanding meal-induced changes of gut hormones, gastric motility, and appetite is crucial for developing therapies for obesity. We investigated glucose-dependent insulinotropic peptide (GIP), glucagon-like peptide-1 (GLP-1), ghrelin, and

Effects of dexmedetomidine on pharyngeal swallowing and esophageal motility—A double‐blind randomized cross‐over study in healthy volunteers

, 2023
BACKGROUND: Sedative agents increase the risk of pulmonary aspiration, where an intact swallowing function is an important defense mechanism. Dexmedetomidine is an α2 -adrenoceptor agonist widely used during procedural sedation due to beneficial ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Dynamics of the β-cardiac myosin auto-inhibited state explain cardiomyopathy pathogenesis

Nature Communications
Cardiac contractility requires precise regulation. A recently discovered form of regulation of cardiac contractility involves a β-cardiac myosin off-state, the Interacting-Heads Motif (CarIHM).

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...
