Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

The Role of Oxidative Stress in Periodontitis
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

A Narrative Review of Candidate Biomarkers of Total Fruit and Vegetable Intake
ABSTRACT While an abundance of cohort studies has suggested that greater consumption of fruits and vegetables (FVs) is associated with reduced risk of chronic diseases, current self‐report based dietary assessment tools are susceptible to biases that can reduce their accuracy in estimating dietary intakes, and consequently, the risk estimates obtained ...

Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Management of Surgical Margins in the Excision of Oral Leukoplakia: A Scoping Review
ABSTRACT Objective To map the literature on management of surgical margins for oral leukoplakia (OL) and proliferative verrucous leukoplakia (PVL). Methods Searches were performed in five electronic databases and gray literature. Studies involving patients undergoing any type of surgical excision of OL or PVL were included.

ABSTRACT Ethylene plays a crucial role in fruit ripening and is perceived by specialised receptor proteins embedded in the endoplasmic reticulum (ER) membrane. As an ethylene antagonist, 1‐methylcyclopropene (1‐MCP) binds to these receptors and delays papaya ripening, but improper use can cause ripening disorders.

Sweet Potato Gene Clusters Control Anthocyanin Biosynthesis and Leaf Morphology
ABSTRACT Sweet potato (Ipomoea batatas) exhibits diversity in pigmentation and leaf morphology, yet the genetic architecture and regulatory organisation underlying these traits remain poorly resolved, particularly with respect to organ‐specific control.
