10-Hydroxy-2-decenoic acid (10-HDA) as the main component of royal jelly has pharmacological characteristics. But the influence of 10-HDA on skin photoaging and photo damage is poorly understood. In the present study, we used 10-HAD immediately after UVA exposure and tested the effects on the attenuation of LMNAÄ150 expression in cultured human dermal fibroblasts Human dermal fibroblasts (cultured cells) were exposed to UVA irradiation. The mRNA level of LMNAÄ150 was determined by Taqman Real-Time PCR Assay. Real-time PCR analysis of LMNAÄ150 transcripts indicated that the level of LMNAÄ150 transcripts was higher in the UVA exposed group than the group treated with 10-HAD after UVA exposure (>8.22-fold). The LMNAÄ150 expression is down-regulated in human dermal fibroblasts after treatment with 10-HDA. It can be concluded that treatment with 10-HDA suppresses the UVA-induced gene expression of LMNAÄ150 and protects skin from UVA-induced photoaging and photo damage.

Surface water chemistry of the River Ganga at Varanasi was analyzed at 10 locations over 3 years (2019-2021) across pre-monsoon, monsoon, and post-monsoon seasons. The study aimed to assess water parameters using principal component analysis (PCA), calculate the water quality index (WQI), determine processes governing water chemistry, evaluate irrigation suitability, and estimate non-carcinogenic health risks. The physical parameters measured included pH (8.

Histone deacetylases (HDACs) play a critical role in chromatin remodelling and modulating the activity of various histone proteins. Aberrant HDAC functions has been related to the progression of breast cancer (BC), making HDAC inhibitors (HDACi) promising small-molecule therapeutics for its treatment. Hydroxamic acid (HA) is a significant pharmacophore due to its strong metal-chelating ability, HDAC inhibition properties, MMP inhibition abilities, and more.

Triggered by the urgent need to tackle the global crisis of multidrug-resistant bacterial infections, in this work, we present a way to overcome chloramphenicol resistance by introducing modifications based on the glycosylation of its hydroxyl groups. The synthesized derivatives demonstrate complete resistance to the action of recombinant chloramphenicol acetyltransferase (CAT) from Escherichia coli and efficacy against methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli ESBL, and Pseudomonas aeruginosa ATCC 27853. Glycosylation gives chloramphenicol an additional advantage - the stable glycosidic form is less toxic to human dermal fibroblasts and has significantly better water solubility than non-glycosylated chloramphenicol.

Human skin is a physical and biochemical barrier that protects the internal body from the external environment. Throughout a person's life, the skin undergoes both intrinsic and extrinsic aging, leading to microscopic and macroscopic changes in its morphology. In addition, the repair processes slow with aging, making the older population more susceptible to skin diseases.

: This study is an attempt to reveal the potential of two types of interpenetrating polymer network (IPN) hydrogels based on poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(N,N-dimethylacrylamide) (PDMAM). These IPNs were evaluated for their potential for dermal delivery of the hydrophobic drug dexamethasone (DEX). : The two types of IPNs were analyzed for their rheological behavior, swelling characteristics, and drug-loading capacity with DEX.
