The influence was investigated of yoghurt and cream cultures on salmonella survival in milk. Salmonella-contaminated milk was blended with yoghurt culture and kept for three hours at the temperature of 43 degrees C; the mixture with cream culture was kept for 20 hours at the temperature of 22 degrees C. The samples were then stored at a room temperature and at the temperature of 4 degrees C. The two milk cultures exerted inhibitory effects on salmonellae within the range of 92.5 to 99.8%. The inhibitory effects depended on the activity of the culture (expressed by titration acidity), storage time and temperature and on the starting concentration of salmonellae.

Lipid membranes form the primary structure of cell membranes and serve as configurable interfaces across numerous applications including biosensing technologies, antifungal treatments, and therapeutic platforms. Therefore, the modification of lipid membranes by additives has important consequences in both biological processes and practical applications. In this study, we investigated a nicotinic-acid-based gemini surfactant (NAGS) as a chemically tunable molecular additive for modulating the structure and phase behavior of liposomal membranes.

An innovative modeling approach for the simulative description of the part quality of rubber materials, including the processing history, is presented in this paper. This modeling approach, the so-called average curing speed (ACS) model, is based on the degree of cure and the average curing speed instead of the conventionally considered temperature approach. Such approach neglects the processing history by calculating only the degree of cure.

The behavior of low-carbon steels (LCSs), a high-strength steel and a nickel-chromium alloy in HCl solutions in the presence of N-containing organic substances has been studied. N-containing organic substances that comprise 1,2,4-triazole in their structure (substance I and substance II) provide comprehensive protection of various steel grades from corrosion and hydrogen absorption by the metal bulk in HCl solutions under both isobaric and isochoric conditions. All the compounds studied reduce, to varying degrees, the concentration of hydrogen adsorbed and absorbed by steel in HCl solutions.

The surface of titanium foil can be modified by heating in the air, in a N flow, and in an NH flow. Upon heating in the air, the elemental Ti gradually transforms to TiO at 550 °C and to rutile TiO at above 700 °C. Treatment in a N flow leads similarly to TiO at 600 °C and TiO at 700 °C, although the overall reaction is slower.

Aim: This study aimed to protect brain functions in patients who experienced in-hospital cardiac arrest through the application of local cerebral hypothermia. By utilizing a specialized thermal hypothermia device, this approach sought to mitigate ischemic brain injury associated with post-cardiac arrest syndrome, enhance survival rates, and improve neurological outcomes as measured by standardized scales.
Methods: A prospective, single-center cohort study was conducted involving patients aged ≥18 years who experienced in-hospital cardiac arrest and achieved return of spontaneous circulation (ROSC).
