Introduction. The aim of this study was to evaluate the influence of the carbomer concentration (used as the gelling agent, in the range 0.5 - 2.0%) on textural and sensory characteristics of gels with 3% panthenol using sensory analysis as subjective and texture analysis as an objective assessment method. An active substance in the gels was panthenol, which also acted as a neutralizing agent of the carbomer. Participants and methods. Twenty female panelists, aged between 20 and 36, participated in the sensory study and had to fulfill a questionnaire regarding product attributes before, during and after application on the skin. Texture analysis was performed on CT3 Texture Analyzer, after each week for a month, and the following parameters were calculated: hardness cycle 1, hardness cycle 2, cohesiveness, adhesiveness, resilience and springiness. Results. The results showed that gels were stable over time and the structure of the gels was preserved regardless of compression. An increase in hardness and resilience was followed by an increase in the concentration of carbomer, while adhesiveness, cohesiveness and springiness did not differ much among different gels. The same trend was noticed when gels were compared during time. Sensory analysis confirmed findings of texture analysis and showed that with the increment of carbomer concentration, stickiness and density also enhanced, while absorption rate and spreadability decreased. Gel with 1% carbomer was chosen by the majority of panelists as favorite and as a gel they would regularly use. Conclusion. The methods of textural and sensory analysis represent valuable approaches in drug/cosmetic product design because they offer insight in the compliance of patients/consumers.

Introduction/purpose: The paper presents interesting research related to the performance analysis of the picture-wise just noticeable difference (JND) prediction model and its application in the quality assessment of images with JPEG compression. Methods: The performance analysis of the JND model was conducted in an indirect way by using the publicly available results of subject-rated image datasets with the separation of images into two classes (above and below the threshold of visible differences). In the performance analysis of the JND prediction model and image quality assessment, five image datasets were used, four of which come from the visible wavelength range, and one dataset is intended for remote sensing and surveillance with images from the infrared part of the electromagnetic spectrum. Results: The pap 86 er shows that using a picture-wise JND model, subjective image quality assessment scores can be estimated with better accuracy, leading to significant performance improvements of the traditional peak signal-to-noise ratio (PSNR). The gain achieved by introducing the picture-wise JND model in the objective assessment depends on the chosen dataset and the results of the initial simple to compute PSNR measure, and it was obtained on all five datasets. The mean linear correlation coefficient (for five datasets) between subjective and PSNR objective quality estimates increased from 74% (traditional PSNR) to 90% (picture-wise JND PSNR). Conclusion: Further improvement of the JND-based objective measure can be obtained by improving the picture-wise model of JND prediction.

Introduction/purpose: The article presents a model of a slow frequency hopping radio in the case of repeater jamming. The aim is to analyze the effectiveness of repeater jamming to a military tactical slow frequency hopping radio. Methods: It is assumed that the repeater jammer will be successful in detecting signals with slow frequency hopping at each hop and that it will perform successful partial jamming of the intercepted communication. Under partial jamming, it is considered that a certain part of the transmission time of each hop will be jammed. A theoretical analysis of the impact of a repeater jammer on a frequency hopping radio was performed based on the definition of the total probability of error. Various parameters that affect the segment of hop duration under jamming were considered. Results: The obtained results show that high effective jamming is achieved even when a short segment of hop duration is jammed. We discuss the conditions for the repeater jammer to detect the signal during each hop and emit the jamming signal with the required strength. It has been shown that increasing the frequency hopping rate can significantly reduce the effectiveness of the repeater jammer. Conclusion: Repeater jammers are highly effective against slow frequency hopping radio communication systems.

Tissue ischemia means insufficient blood flow to a certain area of the body. Interruption of the arterial blood supply leads to an imbalance between metabolic supply and demand and the development of tissue hypoxia. Tissue hypoxia induces metabolic changes that result in inflammation, increased production of reactive oxygen species, and cell death. If adequate blood flow is established in the ischemic tissue, there will be an increase in cellular damage, which is referred to as ischemic-reperfusion injury. Ischemia and ischemia-reperfusion injury are at the root of numerous diseases widely present in modern society, such as myocardial infarction, cerebral insult, acute kidney injury. For now, there is no way to directly affect cellular hypoxia, but the clinical treatment of hypoxic conditions is aimed at modulating global hypoxemia and increasing the amount of oxygen dissolved in the blood. Hyperbaric oxygenation (HBO) is a treatment during which the patient breathes 100% oxygen under a pressure of at least 1.4 atmospheres. Although the use of hyperbaric therapy was recorded as early as the 17th century, today this treatment is approved for a few indications.

Cadmium (Cd) is an extremely toxic metal that is widespread in nature. Due to its favorable properties, it was widely used in the industry for the production of alkaline batteries, accumulators, pigments, and colored alloys. However, it has been shown that exposure to low concentrations of cadmium leads to damage to many organs and organ systems, and the use of this metal in industry is reduced, and it is replaced by other, less harmful materials. Today, fossil fuel combustion and cigarette consumption are important sources of cadmium exposure. Numerous studies have examined the toxic effects of cadmium and they highlight the kidneys, liver, gonads as the organs that suffer the most damage. The kidneys, as the main place of cadmium storage in the body, are mostly exposed to its toxic effects. In the proximal tubular cells of the kidney, exposure to cadmium disrupts transport processes. Although ionized cadmium (Cd 2+) is thought to be largely responsible for the damage that occurs, the role of the cadmium and metallothionein complex (Cd-MT) cannot be ignored. Peritubular exposure to ionized cadmium indirectly leads to a decrease in the activity of the Na + /L-alanine cotransporter and a decrease in the rate of slow repolarization of the luminal membrane, while the Cd-MT complex leads to both direct and indirect inhibition of this transporter. Also, the Cd-MT complex inhibits Na + /Glucosa cotransporter activity. Exposure to cadmium also leads to a decrease in the endocytic uptake of low molecular weight proteins, which is accompanied by microalbuminuria.

Information and communication technologies (ICT) such as smart devices, the Internet of Things and wireless sensor networks are gradually being introduced into the health system for early diagnosis and management of certain diseases. The state of the art of the use of these technologies in mental health identified 37 articles published in indexed high impact journals in the period 2003-2021. The snowball sampling method was used to select these papers. From this literature review, it appears that several of these technologies are used to support the early detection of mental disorders. Various systems based on wearable sensor networks, the Internet of Things and pervasive and ubiquitous computing have been designed and implemented in this sense. However, most of the applications are designed for academic purposes. 29% of the papers deal with the use of mobile technology in the detection of mental illness, while 67% have studied other technologies such as wearable sensor networks. 4% of the papers concern the use of web platforms in the detection and assessment of mental health disorders.
