Summary: Bacterial resistance has been a significant threat to the efficiency of modern treatments, and one common mechanism used by microorganisms to develop resistance is the formation of biofilms. In this study, new compounds were developed to prevent and disrupt biofilms, showing promising potential in combating the increase of microbial resistance.

Summary: The performance of bacterial-treated concrete structures under harsh conditions such as carbonation and chloride exposure was investigated in this study. Bacterial-treated specimens showed improved mechanical strength and reduced penetration properties. The results indicated that these specimens resisted from the deterioration effects of chloride and carbonation exposure and improved their durability properties.

Summary: The study found that salt replacement has a significant impact on bacterial community, physicochemical properties, and sensory characteristics of fermented sausages. It alters bacterial composition, reduces diversity, accelerates drying and ripening processes, decreases resilience and lightness, while maintaining similar comprehensive parameters to normal salt products.

Summary: Mitochondrial-associated membranes (MAMs) play a crucial role in modulating cellular response to myocardial ischemia-reperfusion (IR) injury. The chloride intracellular channel protein (CLIC4), found in MAMs of cardiomyocytes, is involved in regulating ER and mitochondrial calcium homeostasis. Loss of CLIC4 increases myocardial infarction and impairs cardiac function after IR injury. CLIC4 deficiency leads to increased apoptosis and mitochondrial dysfunction in cardiomyocytes.

Summary: The application of bacterial urease driven carbonate precipitation has led to the development of a new biomaterial that can automatically fill the cracks and pores of concrete. Sustained service loads have an impact on the self-healing process and corrosion of reinforced concrete beams containing Sporosarcina pasteurii bacteria. The bio-treated concretes show improved compressive and tensile strength and are able to completely fill cracks, but the healing is not complete. The use of calcium nitrate as a bacteria nutrient decreases the corrosion probability of reinforcements, while calcium chloride increases it. CaCO3 crystals mainly precipitate in the form of calcite and vaterite.

Summary: This study assessed the bioethanol efficiency of Scenedesmus acuminatus CCALA 436 and studied the effects of growing the algae in wastewater and at different concentrations of mepiquat chloride. The pre-treatment efficiencies of different concentrations of calcium oxide on the microalgae biomass were also evaluated. The findings suggest that Scenedesmus acuminatus CCALA 436 grown in wastewater and mepiquat chloride can be used for the treatment of wastewater and the production of ethanol and high-value products.

Summary: Inspired by the design criteria of heteroditopic receptors for ion-pair binding, a new strategy is described to construct a rotaxane transporter (RR[2]) for K+/Cl- co-transport. The use of a rigid axle improves the transport activity with an EC50 value of 0.58 mu M, presenting a significant step toward developing rotaxane artificial channels.

Summary: This paper analyzes the possibility of replacing polyethylene packaging in food products with biodegradable packaging made from biopolymers. The results demonstrate that the addition of ascorbic acid improves the material's strength and barrier properties, while the addition of calcium chloride increases hardness and opacity.

Summary: Aging impairs the function of the central circadian clock, resulting in reduced output signal and decline in rhythm strength. The reduced amplitude of the signal is caused by decreased synchrony among the SCN neurons. The study reveals an increased excitation/inhibition balance and altered Ca2+ homeostasis in SCN neurons of old mice, suggesting their contribution to the altered synchrony within the aged SCN network.

Summary: The study investigated the ability of additives to reduce the formation of acrylamide in simulated sugar cane syrups. Certain combinations of organic acids, B vitamins, and inorganic salts effectively reduced acrylamide formation, but led to an increase in the formation of hydroxymethylfurfural(HMF). Calcium chloride, citric acid, and vitamin B3 were the most effective individual additives, with the combination of citric acid and vitamin B3 showing a significant synergistic effect.

Summary: Gram-negative bacteria have a cell wall that includes lipids, proteins, and glycans, forming a protective layer. The outer membrane contains lipopolysaccharides (LPSs), which play a significant role. Incorporating LPS into artificial membranes is challenging due to their water solubility. This study introduces a new emulsification step to incorporate LPS into specific leaflets of giant unilamellar vesicles (GUVs) and quantifies the LPS content and membrane asymmetry. Diffusion coefficient measurements show that increased LPS concentrations in the membranes lead to decreased diffusivity.

Summary: Artificial cation ionophores have been developed for research and biomedical applications, with some showing potential as small molecules with apoptotic activity. These ionophores act as efficient Na+/K+ exchangers in cell models, inducing apoptosis by perturbing cellular cation homeostasis and promoting ER stress, reactive oxygen species generation, and mitochondria-mediated apoptosis.

Summary: Bacterial proliferation causes stem bending, which shortens the vase life of cut gerbera (Gerbera jamesonii Bolus ex Hook. F.). The antimicrobial compound had different effects on different gerbera cultivars. Stem bending occurrence varied significantly between cultivars. The occurrence of stem bending in 'Kentucky' may be caused by a decrease in flower stem diameter and a weakening of stem strength under conditions of suppressing bacterial proliferation.

Summary: A new 1,2,4-triazole-pyrrolo[1,2-a]pyrazine hybrid system, 6-acylpyrrolo[1,2-a][1,2,4]triazolo[5,1-c]pyrazine, was synthesized using a catalyst-free method. This method involved sequential exposure of pyrrole-2-carbonitrile-derived substrates to DMF-DMA and acyl hydrazide, resulting in the formation of acylated pyrazine and 1,2,4-triazole rings, enabling the installation of various substituents at specific positions on the core skeleton.

Summary: Alcohol dehydrogenases are enzymes that use cofactors for oxidation or reduction reactions of alcohols or carbonyl compounds. They are utilized in green chemistry and have applications in the production of pharmaceuticals. Recombinant enzymes have solved the challenge of producing purified enzymes in large quantities. Engineered alcohol dehydrogenases have been used in asymmetric synthesis in industry. Various methods have been established for regenerating expensive cofactors to make the enzymatic process more efficient and economically viable.
