Plants deploy cellular Ca2+ elevation as a signal for environmental stress signaling. Extracellular ATP (eATP) is released into the extracellular matrix when cells are wounded. DOES NOT RESPOND TO NUCLEOTIDES 1 (DORN1), a key legume-type lectin receptor, senses and binds eATP and activates Ca2+ signaling.

Background/objectives: This study aimed to investigate the lifestyle and the behavioral factors that influence the nutritional status of adolescents from Transylvania, Romania.

Methods: The Global School-Based Student Health Survey (GSHS) was used to collect data from 900 adolescents between 11 and 18 years old from the Transylvania region, Romania. This study assessed nutritional status by calculating BMI indicators adjusted to Z-Score, cut-off points according to the World Health Organization (WHO), using self-reported weight and height; perceived health status; food vulnerability; physical activity; addictive behaviors (cigarette, alcohol and drug consumption); number of hours spent in front of the computer/phone; hand and oral hygiene; sitting time/day; and sleep.

Breastfeeding supplies nutrition, immunity, and hormonal cues to infants. Feeding expressed breast milk may result in de-phased milk production and feeding times, which distort the real-time circadian cues carried by breast milk. We hypothesized that providing expressed breast milk alters the microbiotas of both breast milk and the infant's gut.

Ticks are the second most important hematophagous ectoparasites after mosquitoes and serve as vectors for various pathogens, transmitting them to wild and domestic animals, as well as humans. Argas persicus are the soft ticks that are known to parasitize domestic poultry. Hard ticks are known to be the reservoir of Toxoplasma (T.

The Spodoptera genus is defined as the pest-rich genus because it contains some of the most destructive lepidopteran crop pests, characterized by a wide host range. During feeding, the caterpillars release small amounts of oral secretion (OS) onto the wounded leaves. This secretion contains herbivore-induced molecular patterns (HAMPs) that activate the plant defense response, as well as effectors that may inhibit or diminish the plant's anti-herbivory response.
