Sarcopenia is characterized by the loss of muscle mass and function, increases in mortality rate, and risk of comorbidities in the elderly. This study evaluated the effects of hot water extract (AJHW) and its active compound, oregonin, on muscle atrophy and apoptosis in vitro. AJHW underwent phytochemical analysis.

Manipulation of growth and development of cannabis ( L.) has received considerable interest by the scientific community due to its high value in medicinal and recreational use worldwide. This study was conducted to investigate the effects of LED spectral changes on reactive oxygen species (ROS) and cannabinoid accumulation by provoking growth, pigmentation, photosynthesis, and secondary metabolites production of cannabis grown in an indoor environment.

Triterpenoids exist in a free state and/or in conjugated states, such as triterpene glycosides (saponins) or triterpene esters. There is no information on the enzyme participating in the production of triterpene esters from free triterpenes. Lettuce () contains various pentacyclic triterpene acetates (taraxasterol acetates, ψ-taraxasterol acetates, taraxerol acetates, lupeol acetates, α-amyrin acetates, β-amyrin acetates, and germanicol acetate).

Pinosylvin stilbenes are phenolic compounds mainly occurring in the Pinaceae family. We previously reported that the accumulation of two pinosylvin stilbene compounds, dihydropinosylvin methyl ether (DPME) and pinosylvin monomethyl ether (PME), in Pinus strobus trees was highly enhanced by infection with pine wood nematodes (PWNs: Bursaphelenchus xylophilus), and these two compounds showed strong nematicidal activity against PWNs. In this work, we established a system of pinosylvin stilbene (DPME and PME) production via the in vitro culture of P.

Drought tolerance is a complex trait controlled by many metabolic pathways and genes and identifying a solution to increase the resilience of plants to drought stress is one of the grand challenges in plant biology. This study provided compelling evidence of increased drought stress tolerance in two sugar beet genotypes when treated with exogenous putrescine (Put) at the seedling stage. Morpho-physiological and biochemical traits and gene expression were assessed in thirty-day-old sugar beet seedlings subjected to drought stress with or without Put (0.

Hemp adaptability through physiological and biochemical changes was studied under 10 LED light spectra and natural light in a controlled aeroponic system. Light treatments were imposed on 25 days aged seedlings for 16 h daily (300 µmol m s) for 20 days. Plant accumulated highest Cannabidiol (CBD) in R:B:G light treatment, with relatively higher photosynthetic rate and lower reactive oxygen species, total phenol content, total flavonoid content, DPPH radical scavenging capacity, and antioxidant enzymatic activities.

Stocking density stress is one of the most common management stressors in the poultry industry. The present study was designed to investigate the effect of dietary (SK; 0 and 20 mg/kg diet) and stocking density (SD; 14 and 16 chickens/m) on the antioxidant status, meat quality, and growth performance of native Korean chickens. There was a lower concentration of malondialdehyde (MDA) and a higher concentration of catalase, superoxide dismutase (SOD), and total antioxidant capacity in the serum and leg muscle with the supplementation of SK.

In this study, we report the complete chloroplast (cp) genome of and its relation with other species within the Fabaceae family. The cp genome was 154,870 bp long, with a typical quadripartite structure including a pair of inverted repeat regions (25,866 bp) separated by a large (85,037 bp) and small (18,101 bp) single-copy (SC) region. The genome encodes a total of 84 protein-coding genes, 35 tRNA genes, and 8 rRNA genes.

In this study, we report the complete chloroplast (cp) genome of , a fern member, and comparative analysis with its related family members. The cp genome was 155,983 bp long, with a typical quadripartite structure including a pair of inverted repeat regions (25,614 bp) separated by a large (82,769 bp) and small (21,986 bp) single-copy (SC) region. The genome encodes a total of 88 protein-coding genes, 35 tRNA genes, and 8 rRNA genes.
