In this paper, starting with an introductory review of the applications of liquid crystals and polymer-dispersed liquid crystal systems in (bio)sensors and microfluidics, the possibilities of visualizing self-organization products of liquid crystalline media or field-induced instabilities of liquid crystalline systems are considered. In particular illustrated cases, it is proposed to use FemtoScan software-containing metrological complexes to visualize instabilities in liquid crystalline systems and products of sel [...]

Lung cancer is a leading cause of death among all the cancer worldwide and it has the highest occurrence and mortality rates. Mycobacterium tuberculosis (MTB) induced tuberculosis has been known as one of the risk factors for lung carcinogenesis. The exact mechanism of MTB is understood to date. Several research and epidemiological studies about the link between tuberculosis and lung cancer exist. It has been proposed that tuberculosis causes chronic inflammation, which increases the risk of lung cancer by creating [...]

Illnesses following the degeneration of the nervous system can occur due to aging or genetic mutations and represent a clinical concern. In neurodegenerative diseases, loss of neuronal structure and functions mainly causes cognitive impairment, representing an increasing social burden. In neurodegenerative diseases, the progressive loss of vulnerable populations of neurons in specific regions of the central nervous system was traced to different pathological events, such as misfolded proteins’ accumulation, abnorma [...]

This research aims to model and compare two strategies for locating new hydrogen refueling stations (HRS) in a context of high uncertainty on H2 demand and on the spatial distribution of demand points. The first strategy S1 represented by an agent-based model integrating a particle swarm optimization metaheuristic consists of finding the best HRS locations by adapting to the real evolution of the demand. A second strategy S2 consists in solving a classical capacitated p-median problem based on H2 consumption foreca [...]

The interpretation of aging as an adaptive and programmed phenomenon implies the existence of specific genetically determined and regulated aging-causing mechanisms. This interpretation is in contrast to the explanation of aging as the gradual accumulation of the effects of harmful factors that are only partially countered by natural selection. The subtelomere–telomere theory of aging offers what is required by the interpretation of aging as a programmed phenomenon. The experimentally documented mechanisms that are [...]

Regular physical activity has been proven to improve metabolism, slow aging, and decrease the likelihood of various health conditions such as obesity, type 2 diabetes, and cardiovascular disorders. Hence, dancing was evaluated for its effects on cardiovascular, liver enzymes, and biochemical markers among healthy adults. Forty (40) healthy adults (20-40 years old) were chosen for the study, with an average age calculated. Those with certain health conditions or habits were not allowed to participate. Twenty (20) me [...]

The aim of newborn screening (NBS) program is to detect and manage treatable conditions in the early stages prior to the occurrence of long-term and irreversible sequalae. Phenylketonuria was the first screened disorder, but panels rapidly expanded after the introduction of tandem mass spectrometry technology into the program. Significant differences in the diseases screened by NBS were noted between programs in United States. Therefore, the recommended uniform screening panel was developed in 2006 to include a lis [...]

Cerebrovascular atherosclerosis, and several other cardiovascular (or "inflamm-aging" type) diseases, are more frequent and advanced in subjects with Alzheimer's disease compared with normal aging. In addition, the observed pathogenic link to dementia (and its associated cerebral microvascular damage) is readily explained by alterations of arterial elasticity. A therapeutic strategy to delay dementia could be based upon localized drug delivery, using lipid nanocarriers (i.e., biobased nanoemulsion technology), targ [...]

Pregnancy and postpartum periods are known as sensitive periods in women’s life and COVID-19 pandemic seems to be worsening their mental health with major impacts on exclusive breastfeeding duration. Therefore, the present study aims to fill the gap in the literature by assessing the links between postpartum anxiety and depression symptoms and breastfeeding duration as well as the associated factors during the COVID-19 pandemic. A longitudinal prospective observational study was conducted between November and [...]

Across the industrial sector, compressed air is utilized as an easy-to-use and readily accessible tool in a variety of applications. This tool is commonly misunderstood as being more efficient than it is in reality. Air compression is energy intensive and thus both economically and environmentally costly. Compressed air typically only achieves around ~15% efficiency if judged by the energy delivered from the air, meaning approximately 5-6 kWh are wasted for every 1 kWh of useful work performed by compressed air. Du [...]
