Biochemistry of Bacterial Biofilm: Insights into Antibiotic Resistance Mechanisms and Therapeutic Intervention.

Biofilms, composed of structured communities of bacteria embedded in a self-produced extracellular matrix, pose a significant challenge due to their heightened resistance to antibiotics and immune responses. This review highlights the mechanisms underpinning antibiotic resistance within bacterial biofilms, elucidating the adaptive strategies employed by microorganisms to withstand conventional antimicrobial agents. This encompasses the role of the extracellular matrix, altered gene expression, and the formation of persister cells, contributing to the recalcitrance of biofilms to eradication.

Bidimensional Increment Entropy for Texture Analysis: Theoretical Validation and Application to Colon Cancer Images.

Entropy algorithms are widely applied in signal analysis to quantify the irregularity of data. In the realm of two-dimensional data, their two-dimensional forms play a crucial role in analyzing images. Previous works have demonstrated the effectiveness of one-dimensional increment entropy in detecting abrupt changes in signals.

A New Hope for the Patients of Non-Alcoholic Steatohepatitis: FDA Gives Green Signal for Resmetirom Use.

Background And Aims: Non-Alcoholic Steatohepatitis (NASH), a severe form of Non-Alcoholic Fatty Liver Disease (NAFLD), is characterized by inflammation and fibrosis in the liver, often progressing to cirrhosis and hepatocellular carcinoma. Despite its rising prevalence and significant disease burden, effective pharmacological treatments have been limited to lifestyle modifications and surgical interventions. Recently, resmetirom, a thyroid hormone receptor-β agonist, received FDA approval for treating NASH, offering new hope to patients.

Rapid Microwave Fixation of the Brain Reveals Seasonal Changes in the Phosphoproteome of Hibernating Thirteen-Lined Ground Squirrels.

Hibernating mammals such as the thirteen-lined ground squirrel () experience significant reductions in oxidative metabolism and body temperature when entering a state known as torpor. Animals entering or exiting torpor do not experience permanent loss of brain function or other injuries, and the processes that enable such neuroprotection are not well understood. To gain insight into changes in protein function that occur in the dramatically different physiological states of hibernation, we performed quantitative phosphoproteomics experiments on thirteen-lined ground squirrels that are summer-active, winter-torpid, and spring-active.

Synthesis and antibacterial evaluation of quinoline-sulfonamide hybrid compounds: a promising strategy against bacterial resistance.

Antibiotic-resistant bacteria are a serious global health threat, making infections harder to treat and increasing medical costs and mortality rates. To combat resistant bacterial strains, a series of compounds (QS1-12) were synthesized with an excellent yield of 85-92%. Initial assessments of these analogues as potential antibacterial agents were conducted through a preliminary screening against a panel of diverse bacterial strains.
