Uses of Chemical Technologies for Meat Decontamination.

Traditional meat preservation techniques such as smoking, drying, and salting have various shortcomings and limitations in effectively reducing microbial loads and maintaining meat quality. Consequently, chemical compounds have gained attention as promising alternatives for decontamination, offering the potential to extend shelf life and minimize physical, chemical, and sensory changes in meat. Chlorine-based compounds, trisodium phosphate, organic acids, bacteriocins, lactoferrin, and peracetic acid are technologies of recent industrial applications that inhibit spoilage and pathogenic microorganisms in meat.

Echocardiographic predictors of surgical outcomes in pulmonary atresia with intact ventricular septum and development of a discriminatory calculator: an Australian tertiary institution experience.

Introduction: Pulmonary atresia with intact ventricular septum is a rare congenital cardiac lesion with significant anatomical heterogeneity. Surgical planning of borderline cases remains challenging and is primarily based on echocardiography. The aim was to identify echocardiographic parameters that correlate with surgical outcome and to develop a discriminatory calculator.

A national Australian Congenital Heart Disease registry; methods and initial results.

Background: Although several National Data Registries for Congenital Heart Disease (CHD) exist, few are comprehensive and contemporary. A National Australian CHD Registry has been developed that aims to redress this by creating the first comprehensive data collection for CHD children and adults, initially across Australia.

Methods: We defined and collected a minimum dataset of demographics, diagnoses, and procedures from people with CHD presenting at participating quaternary CHD services Australia-wide.

Covalent Attachment of Horseradish Peroxidase to Single-Walled Carbon Nanotubes for Hydrogen Peroxide Detection.

Single-walled carbon nanotubes (SWCNTs) are desirable nanoparticles for sensing biological analytes due to their photostability and intrinsic near-infrared fluorescence. Previous strategies for generating SWCNT nanosensors have leveraged nonspecific adsorption of sensing modalities to the hydrophobic SWCNT surface that often require engineering new molecular recognition elements. An attractive alternate strategy is to leverage pre-existing molecular recognition of proteins for analyte specificity, yet attaching proteins to SWCNT for nanosensor generation remains challenging.

Relationship between clarithromycin MICs and treatment responses in Mycobacterium avium complex pulmonary disease.

Background: Mycobacterium avium complex pulmonary disease (MAC-PD) is a chronic lung condition with rapidly increasing prevalence worldwide. Macrolides like azithromycin and clarithromycin are the backbone of long-term antibiotic therapy for progressive MAC-PD. The impact of minimum inhibitory concentrations (MICs), especially within the susceptible range, for macrolides on treatment responses remains unclear.
