Chiral Self-Assembly of a Pyrene-Appended Glutamylalanine Dipeptide and Its Charge Transfer Complex: Fabrication of Magneto-Responsive Hydrogels and Human Cell Imaging.

The formation of a robust, self-healing hydrogel of a novel pyrene-appended dipeptide, Py-E-A (L-Glutamic acid short as E; L-Alanine short as A) is demonstrated. Detailed studies suggest that nanoscopic fibers with a length of several micrometers have formed by chiral self-organization of Py-E-A gelators. Additionally, live human PBMCs imaging is shown using the Py-E-A fluorophore.

Theoretical study of a new molecular ion species BeN: molecular states and cross sections for electronic excitation and dissociation.

We present here a theoretical study of a new molecular ion species BeN, which has not been reported before. Using a good quality configuration interaction model, we first undertake a configuration interaction calculation of the molecular states to obtain the potential energy curves of several low lying states of BeN and the dipole and transition dipole moments of some of its states as a function of the internuclear distance. We find the ground state to be bound and of X Σ character having a shallow minimum at = 2.

Potential of carboxymethyl cellulose solution to increase the shale stability.

Slope failures in Bangladesh's Chittagong division are a growing concern, with fatalities increasing from 19 in 2000 to 162 in 2017 and projected to rise further. This study aims to identify the most vulnerable rock formation and assess Carboxymethyl Cellulose (CMC) as a solution for enhancing shale strength and mitigating slope failures. The research began by evaluating weathering susceptibility and stability of different rock layers, revealing the high instability of shale in the Bhuban Formation.

First Three Years' Experience of Mucopolysaccharidosis Type-I Newborn Screening in California.

Objective: To report on the first 3 years of mucopolysaccharidosis type I (MPS I) newborn screening (NBS) in the large and diverse state of California.

Study Design: The California Genetic Disease Screening Program began universal NBS for MPS I on August 29, 2018. The screening uses a 2-tiered approach: an α-L-iduronidase (IDUA) enzyme activity assay followed by DNA sequencing for variants in the IDUA gene.
