AI Article Synopsis
- The speckle imaging technique effectively monitors the growth of bacteria in real-time, making it a reliable method for studying bacterial kinetics.
- A simulation using Bacillus thuringiensis and calibrated microspheres of varying concentrations showed how light interacts with bacterial density.
- Results indicate that as the medium's scattering coefficient increases, speckle grain size decreases, highlighting two key growth phases: exponential growth and stationary phase involving sporulation and cell lysis.
Article Abstract
The speckle imaging technique has been proven to be a reliable and effective method for real-time monitoring of the growth kinetics of any bacterium in suspension. To understand the interaction between the light and the bacterial density, a simulation of the bacterial growth of Bacillus thuringiensis was performed using calibrated microspheres of different concentrations and sizes. Results show that the decrease of speckle grain size with the increase of the medium scattering coefficient reveals the two essential phases of the bacterial growth: the exponential phase where the number of the bacteria increases and the stationary phase where sporulation and cell lysis occur.

Effect of packaging materials and storage temperature on the shelf stability of paste.
Front Nutr
January 2025
Ethiopian Institute of Agricultural Research, Head Quarter, Food Science and Nutrition Research, Addis Ababa, Ethiopia.
Background: It is well known that deterioration is a big concern in the food supply chain. The problem is more serious in handling of traditional foods in developing country such as Ethiopia, due to the limited knowledge about the optimum processing, packaging and storage conditions.
Objective: This study aimed to investigate the effect of packaging material and storage condition on the shelf life of Ethiopian traditional paste.
Multi-target gene therapy AUP1602-C to improve healing and quality of life for diabetic foot ulcer patients: a phase I, open-label, dose-finding study.
Ther Adv Endocrinol Metab
November 2024
Aurealis Therapeutics, Microkatu 1, Kuopio 70210, Finland.
Background: Diabetic foot ulcer (DFU) is a common and highly morbid complication of diabetes with high unmet medical needs. AUP1602-C, a topical four-in-one gene therapy medicinal product (GTMP), consisting of a strain that produces fibroblast growth factor-2, interleukin-4, and colony-stimulating factor-1, is a promising novel treatment for DFU.
Objectives: The aim of this first-in-human study was to investigate whether AUP1602-C is safe and effective in improving wound healing and quality of life (QoL) in patients with non-healing DFU (nhDFU), and to determine the recommended phase II dose.

Lixiahe Institute of Agricultural Sciences in Jiangsu Province; National Experimental Station of Yangzhou for Agricultural Microbiology, Yangzhou, Jiangsu 225007, China.
Objective: To investigate the physiological characteristics of subspecies (Bti) with double mutations of and genes and to assess the activity of Bti against larvae of under different external factors, so as to provide the theoretical evidence for the use of engineered bacteria of Bti for effective mosquito control.
Methods: wild-type strain Bt-59 and Bt-59 strain with mutation [Bt-59 (Δ)] were cultured in nutrient broth media for 24 hours, and Bt-59 strains with mutation [Bt-59 (Δ)] and double mutations of and [Bt-59 (Δ)] were cultured in nutrient broth media for 48 hours. Then, 5 μL of culture media were transferred to glass sides, and cell morphology and mother cell lysis were observed under an optical microscope.
Rational Design of Quinoidal Conjugated Polymers for Photothermal Antibacterial Therapy.
Macromol Rapid Commun
January 2025
School of Materials Science and Engineering, Hebei University of Technology, Tianjin, 300401, P. R. China.
The increasing prevalence of antibiotic resistance, driven by the overuse and misuse of conventional antibiotics, has become a critical public health concern. Photothermal antibacterial therapy (PTAT) utilizes heat generated by photothermal agents under light exposure to inhibit bacterial growth without inducing resistance, attracting more and more attention. Quinoid conjugated polymers, especially para-azaquinodimethane (AQM) polymer, are a class of organic semiconductors known for efficient π-electron delocalization, near-infrared absorption, and narrow bandgap, showing great potential in the application of photothermal reagents.

Institute of Grassland Research, Chinese Academy of Agricultural Sciences, Hohhot, 010010, China.
Background: While Gangba sheep being well known for their unique flavour and nutritional value, harsh environmental factors negatively affect their growth and development, leading to poor productivity. The gastrointestinal tract microbiota plays an important role in host nutrient absorption and metabolism. The identification of dynamic changes in the gastrointestinal microbial communities and their functions is an important step towards improving animal production performance and health.
