Cells have the capability of defending themselves from various stressors by activating a genetic program with the production of substances known as heat shock proteins and their regulatory partners, the heat shock transcription factors. In this article, heat shock proteins are discussed, including their roles in pathophysiology and as possible pharmacologic targets to treat disease. Multiple investigations have demonstrated an elevation in heat shock proteins in patients with systemic hypertension, coronary artery disease, carotid atherosclerosis, and myocardial infarction and ischemia. As we further understand how to manipulate their expression, we can explore pharmacologic interventions and gene transfection techniques that can safely be used in humans.

With freshwater resources becoming scarce worldwide, mariculture is a promising avenue to sustain aquaculture development, especially by incorporating brackish and saline groundwater (GW) use into fish farming. A 75-day rearing trial was conducted to evaluate fish growth, immune response, overall health, and water quality of Chelon ramada cultured in brackish GW and fed on a basal diet (BD) augmented with rosemary oil (RO) or RO + zymogen forte™ (ZF) as an anti-flatulent. Five treatments were administrated in triplicate: T1: fish-fed BD without additives (control group); T2: fish-fed BD + 0.

Biostimulants are an emerging and innovative class of products that may mitigate the adverse effects of extreme heat, but research on their efficacy in fruit crops is limited. This study addressed this knowledge gap by evaluating the performance of three biostimulants, FRUIT ARMOR™, Optysil®, and KelpXpress™ [active ingredients glycine betaine, silicon, and kelp (Ascophyllum nodosum) extract, respectively] applied to three raspberry genotypes exposed to high temperatures (T ≥ 35 °C/day) inside a glasshouse. 'Meeker' consistently maintained high chlorophyll fluorescence (F/F) and photosynthesis under control and biostimulant treatments.

Lipid nanoparticle (LNP)-mediated RNA delivery holds significant potential for the treatment of various liver diseases. Ionizable lipids play a crucial role in the formulation of LNPs and directly influence their delivery efficiency. In this study, we introduced an innovative concept by incorporating an ether bond into the hydrophobic tail of ionizable lipids for the first time.
