This study investigates the nature and interplay of noncovalent interactions (NCIs)─tetrel bonds (TB), hydrogen bonds (HB), and halogen bonds (XB)─in molecular assemblies formed between trifluorogermyl hypochlorite (FGeOCl) and hydrogen cyanide (HCN). Using a combination of high-level computational methods, we explored the geometric, energetic, and electronic properties of dimers, trimers, and tetramers formed in different molar ratios of interacting reagents. Various analyses reveal a significant cooperativity between TB and HB, which mutually reinforce each other, while XB interactions are diminished in the presence of TB and HB.

Cancer is one of the leading causes of mortality around the world and most of our conventional treatments are not efficient enough to combat this deadly disease. Harnessing the power of the immune system to target cancer cells is one of the most appealing methods for cancer therapy. Nucleotide-based cancer vaccines, especially deoxyribonucleic acid (DNA) cancer vaccines are viable novel cancer treatments that have recently garnered significant attention.

Theranostics is a way of treating illness that blends medicine with testing. Specific characteristics should be present in the best theranostic agents for cancer: (1) the drugs should be safe and non-toxic; (2) they should be able to treat cancer selectively; and (3) they should be able to build up only in the cancerous tissue. Liposomes (LPs) are one of the most efficient drug delivery methods based on nanotechnology.

This study aimed to develop bead-free nanofibers for effective omega-3 encapsulation using optimal mixing ratios of whey protein isolate (WPI)/polyvinyl alcohol (PVA) blends via electrospinning method. Various WPI-PVA ratios (100:0, 90:10, 80:20, 70:30, 60:40, 50:50 v/v) were examined for surface tension, viscosity, and conductivity. SEM images revealed uneven nanofibers with bead at 90:10 and 80:20 ratios, while the 70:30 ratio produced uniform and bead-free nanofibers with an average diameter of 262.

Reprod Fertil

January 2025

M Bazrgar, Department of Genetics, Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR, Tehran, Iran., Tehran, Iran (the Islamic Republic of).

It is believed that aneuploid embryos release cell-free DNA (cfDNA) into the blastocyst cavity during the self-correction process through the apoptotic mechanism. This study aimed to develop less invasive methods for predicting ploidy status by investigating how ploidy status affects blastocoel fluid DNA (BF-DNA) levels and apoptotic gene expression as indicators of embryo viability. Human blastocysts were classified into three groups; Survivable Embryo (SE), Fatal Single and double Aneuploidy (FSDA), and Multiple Aneuploidy (MA) using array comparative genomic hybridization (array-CGH) by trophectoderm (TE) biopsy.
