Polycystic ovarian syndrome is a heterogeneous endocrine disorder characterized by ovarian cysts, anovulation, endocrine variations, which includes oligo-amenorrhea along with associated subfertility and hyperandrogenism manifested as acne, hirsutism, and male-pattern alopecia. Coumarins are fused benzene and pyrone ring systems that exhibit a wide spectrum of bioactivities. This study aimed to investigate the effects of 3-acetyl coumarin (3-AC) on polycystic ovarian syndrome in female rats.

The effects of cosmic-ray bombardment of chiral molecules in the interstellar medium are simulated in the laboratory by performing radiolysis experiments of pure α-pinene ices at four different temperatures. The identification and significance of α-pinene have not been fully understood because of the insufficient amount of spectral information of these compounds at low temperatures. A comparison of the temperature dependence of the mid-infrared spectra of pure α-pinene ices before and after irradiation its irradiation by 61.

The application of visible light as an energy source provides a new avenue in organic transformation due to its mildness, efficiency and selectivity. In fact, recent years have witnessed remarkable advances in photoinduced decarboxylative coupling reactions involving carboxylic acids and their derivatives. Under appropriate photoredox conditions they undergo single electron transfer (SET), resulting in reactive radicals which can assemble with suitable reaction partners.

Enhancement of neuronal plasticity by small-molecule therapeutics protects cognitive skills and also ameliorates progressive neurodegenerative pathologies like Alzheimer's disease (AD) and dementia. One such compound, a novel histone deacetylase 2 (HDAC2) inhibitor named JRM-28, was shown here to enhance dendritic strength, augment spine density, and upregulate post-synaptic neurotransmission in hippocampal neurons. The molecular basis for this effect correlates with JRM-28-induced upregulation of the transcription of cAMP response element-binding protein(CREB), induction of its transcriptional activity, and subsequent stimulation of expressions of CREB-dependent plasticity-associated genes, such as those encoding N-methyl-D-aspartate (NMDA) receptor subunit NR2A and the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit GluR1.
