SE-HPLC separation of myosin complex with tannins from bearberries (Arctostaphylos uva-ursi L. Sprengel) leaves - a short report.

open access: yesCzech Journal of Food Sciences, 2009
Phenolic compounds were extracted from bearberry (Arctostaphylos uva-ursi L. Sprengel) leaves into 95% (v/v) ethanol. The tannin constituents were separated from the crude extract using Sephadex LH-20 column chromatography with 95% (v/v) ethanol and 50% (

Molecular Model of the Contractile Ring

open access: yes, 2005
We present a model for the actin contractile ring of adherent animal cells. The model suggests that the actin concentration within the ring and consequently the power that the ring exerts both increase during contraction.

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

open access: yesAdvanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Chromosome movement in lysed mitotic cells is inhibited by vanadate. [PDF]

open access: yes, 1978
Mitotic PtK1 cells, lysed at anaphase into a carbowax 20 M Brij 58 solution, continue to move chromosomes toward the spindle poles and to move the spindle poles apart at 50% in vivo rates for 10 min.

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

open access: yesAdvanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

VE‐Cadherin–Actin Regulation Promotes Mechanotransduction and Monolayer Maturation Involving a Tension‐Sensitive Intermediate State

open access: yesAdvanced Science, EarlyView.
This study investigates how endothelial monolayers balance cohesion and plasticity during mechanical stimulation. In HUVECs, shear stress induces a tension‐sensitive intermediate state in which junctional VE‐cadherin and actomyosin relaxation levels coordinate actin/integrin remodeling. This rapid, reversible state strengthens cell junctions, preserves

Mechanical Overloading‐Induced Nanomineral Crystal Perturbation from the Osteochondral Interface: A Potential Initiator of Osteoarthritis

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Effect of the Partial Substitution of NaCl with L-Arg on the Gel Properties and Aggregation Behavior of Beef Myosin

open access: yesFoods
With 0.3 M KCl replacing NaCl, the effect of L-Arg on beef myosin’s gel, structure, and aggregation was investigated. L-Arg could enhance hydrogen and ionic bonds, increasing myosin solubility and reducing turbidity.

The effect of Arginine, Lysine and Histidine in the myosin secondary structure by circular dichroism and Raman spectroscopy

open access: yesCyTA - Journal of Food, 2019
Amino acids containing L-Arginine (Arg), L-Lysine (Lys) and L-Histidine (His) are recognized to increase the solubility of myosin at low ionic strength, but there is a difference in the researchers’ views on their effects on the secondary structure of ...

Genetic Diagnosis and Discovery Enabled by Large Language Models

open access: yesAdvanced Science, EarlyView.
We demonstrate that large language models (LLMs) can facilitate genetic diagnosis and discovery. LLMs were used to solve four types of genetic problems of sequentially increased complexity. An LLM‐based pipeline could analyze genetic variants in the genomic sequences of human hearing loss or rare genetic disease patients and assist in identifying ...
