3D printed PLA has already been demonstrated for several biotechnological applications, including enzymes immobilization. The prerequisites for an efficient screening assay include using small volumes of reagents, low cost, and rapid screening of large numbers of compounds and extracts. Hence, assays based on microtiter plates are predominant. Thus, designing and fabricating scaffolds on a similar scale, which could serve as immobilization carriers, and their recruitment in inhibitors screening studies is of great [...]

Experimental phenomenology is the investigation of phenomenological practices and their effects. To engage in a phenomenological practice means to focus attention on aspects of one’s experiences (e.g., sense impressions or body sensations) while adopting a specific kind of attitude (e.g., an explorative attitude) according to some set of instructions. The basic assumption is that the regulation of attention and attitudes involved in such practices may have effects on people’s health and quality of life. The present [...]

Lignin is the most abundant renewable source of aromatics on earth, and conversion of it to chemicals and fuels is needed to build an economically viable renewable biofuels industry. Biological routes to converting lignin to fuels and chemicals involve depolymerizing lignin using lignin-degrading enzymes that catalyze the breaking of ether and carbon-carbon bonds in the phenolic and non-phenolic subunits of lignin. Laccases are a crucial class of lignin-degrading enzymes and are copper-containing enzymes capable of [...]

In this study, we investigated the oligomerization mechanism of the Fischer-Tropsch synthesis catalyzed by a cobalt-based catalyst supported by SBA-15. The Co/SBA-15 catalyst contained 20% w/w of cobalt. It was prepared by the wet impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption-desorption, temperature-programmed reduction (TPR), and scanning electron microscopy coupled to X-ray energy dispersion spectroscopy (SEM-EDS). The FT synthesis was conducted in a slurry bed reactor operating [...]

Burnout is a chronic state of exhaustion caused by prolonged stress. Medical training has been shown to leave many medical students vulnerable to burnout, which can negatively impact their health and patient care. While resilience has been associated with lower burnout, the mechanisms through which resilience reduces burnout are not well established. Therefore, this study aimed to investigate whether difficulties with emotion regulation mediate the relationship between resilience and burnout among medical students. [...]

Fear has been the most common emotional response to the COVID-19 pandemic, and excessive fear is associated with various indices of psychological distress, particularly loneliness. Although most people have experienced pandemic-related fear and distress, certain groups who are on the front of service provision have experienced the pandemic in distinct ways, owing to its impact on the nature of their work. Schoolteachers represent one such group; therefore, it is imperative to identify resources that can safeguard a [...]

Schools play an integral role in providing opportunities for children of all ages to be exposed to nutrition education. There are a variety of ways children can receive nutrition education in the school setting, such as explicit lessons, modeled dialogue, and exposure to nutrition-based principles. However, there continues to be a disconnect between teacher perceptions of nutrition education and time spent implementing it in the classroom. Nutrition education can come in many forms, including hands-on gardening and [...]

Lyme disease is a spirochetal illness transmitted primarily through the bite of ticks. The disease has a broad spectrum of comorbid conditions including osteoarticular, cardiovascular, and neurological involvement. In addition, clinical variability depends on the age of affected individuals. The Center for Disease Control recognizes the disease as an epidemic and mentions it to be a major morbidity burden in our environment because of the frequent lack of diagnosis and early treatment. Scientific literature mention [...]

Health-related behaviours (HRBs) have been considered one of the most critical public health issues, especially for those with special educational needs (SEN). Previous research suggests that health-related behaviours are highly likely to impact well-being and academic achievement. Diet is a crucial health-related behaviour that needs to be investigated along with factors such as sleep and exercise. The present study used data from the Cornish Academies Project, and secondary analyses were conducted to investigate [...]

Microvascular endothelial dysfunction precedes, often by decades, the cognitive decline associated with Alzheimer's disease. Hence, preservation of a healthy cerebrovascular endothelium can be an important therapeutic target. By incorporating appropriate drug(s) into biomimetic (lipid cubic phase) nanocarriers, one obtains a multitasking combination therapeutic which targets certain cell-surface scavenger receptors, mainly class B type I (i.e., SR-BI), and crosses the blood-brain barrier. Documented similarities in [...]

Managing water resources offers crucial information about the availability of water supplied from catchments into water bodies, which plays a vital role in water resource engineering. However, due to changes in the global climate, hydrological modeling of river catchments is critically crucial for socio-economic development and livelihoods. Numerous models evaluate runoff from precipitation, but the SCS-CN method is fundamental and the most widely recognized for calculating runoff. This research evaluates runoff de [...]

Microbial and viral pathogens have emerged as key contributors to cancer development. Research conducted in the last twenty years has significantly enhanced our comprehension of the cancer-causing capabilities of infectious agents. An illustrative instance is gastric cancer (GC), which is closely associated with Helicobacter pylori (H. pylori) and Epstein-Barr virus (EBV) infections, with approximately 90% of non-cardia GC cases attributed to H. pylori infection and around 10% linked to EBV. Despite significant res [...]

The ever-growing urgency to combat climate change has led the civil construction industry to develop and adopt sustainable construction materials and methods. The so-called recycled concrete aggregate (RCA) emerges as an alternative to decrease the carbon footprint of new concrete construction, the disposal of waste concrete, and the use of non-renewable natural resources such as cement and aggregates. RCA can be produced from crushing waste concrete; yet challenges remain when using RCA in concrete especially its [...]

The human brain has been repeatedly shown to exhibit intercellular/somatic genomic variations at the chromosomal level, which are involved in the neuronal diversity in health and disease. Brain-specific chromosomal mosaicism (aneuploidy) and chromosome instability play a role in the normal and pathological neurodevelopment, neurodegeneration and aging of the central nervous system. Regardless of achievements in somatic cell (single-cell) genomics, there is still no consensus on the amounts of chromosomally abnormal [...]

Visual external costs are significant elements in the cost-benefit analysis of wind farm locations. This has been demonstrated well in the literature. However, in the assessment of the visual costs, a large share of the earlier studies used no or only simplistic visualizations of the visual impacts at stake. The cost estimates thus rely on the respondents’ ability to imagine the visual impacts associated with wind turbines of different sizes and at different locations. This has been argued to potentially reduce the [...]

Oil and gas wellbores that are drilled into the earth’s crust need to be plugged and abandoned, to restore the geological seals once they are no longer producing. The main aim of Plugging and abandonment (P&A) is to ensure that there is no leakage of hydrocarbons into the environment. Since offshore P&A is challenging due to subsurface temperature and pressure conditions, testing zeolite as an additive for improvement of cement properties is an intriguing research topic.

This led to decades of research to ascertain the effect of altered antioxidant defense systems on aging and mortality in an array of species using reverse genetics and dietary manipulation. Within invertebrates, the data generally support the Free Radical Theory in that overexpression of antioxidant enzymes or dietary supplementa [...]
