Microstructural mapping of neural pathways in Alzheimer's disease using macrostructure-informed normative tractometry.

Introduction: Diffusion-weighted magnetic resonance imaging (dMRI) is sensitive to the microstructural properties of brain tissues and shows great promise in detecting the effects of degenerative diseases. However, many approaches analyze single measures averaged over regions of interest without considering the underlying fiber geometry.

Methods: We propose a novel macrostructure-informed normative tractometry (MINT) framework to investigate how white matter (WM) microstructure and macrostructure are jointly altered in mild cognitive impairment (MCI) and dementia.

Dynamic analysis of fractal-fractional cancer model under chemotherapy drug with generalized Mittag-Leffler kernel.

Background And Objective: Cancer's complex and multifaceted nature makes it challenging to identify unique molecular and pathophysiological signatures, thereby hindering the development of effective therapies. This paper presents a novel fractal-fractional cancer model to study the complex interplay among stem cells, effectors cells, and tumor cells in the presence and absence of chemotherapy. The cancer model with effective treatment through chemotherapy drugs is considered and discussed in detail.

A Catalytic, Enantioselective Sulfamate Tethered -Michael Cyclization.

We show the first examples of enantioselective cyclization reactions of tethered sulfamates onto pendant α,β-unsaturated esters, ketones, and thioesters. This reaction is promoted by a new chiral bifunctional guanidine catalyst and is operationally very simple. A variety of primary sulfamates and sulfamides were examined, and in many cases, products were delivered in excellent yields and enantiomeric ratios.

Plant growth-promoting Bacillus amyloliquefaciens orchestrate homeostasis under nutrient deficiency exacerbated drought and salinity stress in Oryza sativa L. seedlings.

Nutrient deficiency intensifies drought and salinity stress on rice growth. Bacillus amyloliquefaciens inoculation provides resilience through modulation in metabolic and gene regulation to enhance growth, nutrient uptake, and stress tolerance. Soil nutrient deficiencies amplify the detrimental effects of abiotic stresses, such as drought and salinity, creating substantial challenges for overall plant health and crop productivity.

Combating chlorine-resistant marine Klebsiella pneumoniae biofilms with chlorine-tolerant bacteriophages.

Biofilm formation presents a significant challenge in health care, food industries, water distribution systems, etc. In addition to their inherent resistance to various stresses and biocides, emerging resistance against widely used biocides like chlorine is a growing concern. The strong link between chlorine resistance and the development of antibiotic resistance among microbes further exacerbates this issue.
