Comparative Analysis of Blood MMP-9 Concentration in Alcohol- and Opioid-Addicted Patients.

Background/objectives: In brain physiology and disease, MMP-9 is a significant and apparently peculiar factor. Numerous studies have implicated neuroinflammatory processes involving MMP-9 in the pathophysiology of addiction. This study aims to evaluate plasma MMP-9 level as a biomarker for the stages of alcohol and opioid addiction.

Assessment of Arthrobacter oxydans Subcellular Structural Stability in Response to Metal Action using Differential Scanning Calorimetry.

Despite significant efforts in recent years to clean up the environment, pollution remains a major issue. Bioremediation is the most effective and ecologically friendly way to clean and regenerate chemically polluted environments. Microorganisms' biostabilization of soluble and insoluble forms of hazardous contaminants can be employed to remediate areas contaminated with heavy metals.

Thermal analysis of whole bacterial cells exposed to potassium permanganate using differential scanning calorimetry: a biphasic dose-dependent response to stress.

The DSC technique applied to the study of the toxic impact of permanganate on bacterial cell culture detected the lack of linearity in the dose-response effect. The results were confirmed by the traditional assay of colony forming ability. The changed pattern of thermal spectra of A.

A calorimetric characterization of Cr(VI)-reducing Arthrobacter oxydans at different phases of the cell growth cycle.

This is the first of a series of calorimetric studies designed to characterize and understand survival mechanisms of metal-reducing bacteria isolated from metal-polluted environments. In this paper we introduce a new concept of thermal spectrum of the endothermic melting of complex biological systems (e.g.
