Mesoporous silica exhibits a diverse range of applications owing to its pore structure and inter-pore correlation. Consequently, quantitative characterization of its mesoscopic structure is extremely crucial to reciprocate its potential applications. In this work, we utilized the chemical and aerosol routes to successfully synthesize granular, porous silica with an average pore size in the range of ∼5-10 nm and different degrees of structural correlation among its pores.

Amino-quinolines are potential candidates that may provide some insight into the current chemotherapeutic research due to their demonstrated anti-cancer activity. This led us to synthesize and explore a new amino-azo-quinoline ligand H2L 1 and its square planar nickel(II) complexes [Ni(HL)(OAc)], 2 and [Ni(HL)Cl], 3 and the structures were determined by SCXRD. Theoretical investigation of redox orbitals of the complexes discloses that the reduction process is due to ligand reduction whereas both metal and ligand are contributing towards oxidation.

Methyleugenol (ME) has been classified as a "group 2B carcinogen" by IARC. Its positional isomer methylisoeugenol (MIE) has been considered to be of "generally recognized as safe'' status by FDA. ME was more cytotoxic than MIE in cultured mouse primary hepatocytes.

Breast cancers of the IntClust-2 type, characterized by amplification of a small portion of chromosome 11, have a median survival of only five years. Several cancer-relevant genes occupy this portion of chromosome 11, and it is thought that overexpression of a combination of driver genes in this region is responsible for the poor outcome of women in this group. In this study we used a gene editing method to knock out, one by one, each of 198 genes that are located within the amplified region of chromosome 11 and determined how much each of these genes contributed to the survival of breast cancer cells.

Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.
