Additive Manufacturing Techniques for Fabrication of Bone Scaffolds for Tissue Engineering ApplicationsAbstract
Bone tissue engineering (BTE) as a modern and more effective treatment for bone defects has recently received lots of attention. One of the pivotal parts of BTE is the “scaffold”, which functions as an indwelling carrier of cells and additives, as well as, providing a foundation for cell growth and eventually forming new, native-like bone. Up to now, many methods and materials have been employed to manufacture bone scaffolds. This review focuses on providing both basic knowledge of BTE as well as possible methods o [...] 4148 30678 |
A Narrative Review of the TP53 and Its Product the p53 ProteinAbstract
The main purpose of this paper was to generate a narrative review related to the current knowledge of the TP53 gene and its product, the p53 protein. It was also attempted to elucidate the different p53 reactivation strategies of great interest, as various small molecules are being studied to reactivate mutant p53. PubMed and ScienceDirect were searched for p53, mutant p53, and wild-type p53 limited by the title filter through the end of 2022. The collected articles were studied, evaluated and summarized. In the sh [...] 4139 30663 |
Cerebral Palsy: An Overview of Etiology, Types and ComorbiditiesAbstract
Cerebral Palsy (CP) is the most frequent cause of childhood disability. CP occurs in 1 out of every 345 children in the United States. CP is primarily a motor disease that is the result of an insult to the brain that occurs during the prenatal or early postnatal period when the brain is still developing. CP is not a single disease but a physical description of motor impairments that originate from multiple etiologies. This article briefly discusses the etiologies, classification and management of the neurologic med [...] 3678 30523 |

Open Access Short Communication Impact of Covid-19 Pandemic on Air Transport: Overview and Implicationsby
Abstract
The current situation of the COVID-19 pandemic has led to multiple changes in the international market as well as in the lifestyle of people worldwide. The transport sector has undoubtedly been one of the most affected sectors due to restrictions imposed by the governments across the world to protect the health of their citizens, particularly the restrictions imposed on the operation of airlines. On the other hand, the reduction in travel by means of transport has contributed in part to the improvement in the envir [...] 4852 30492 |
Exercise and Nutritional Strategies to Promote Weight Loss: A Narrative Review1Abstract
Obesity has historically been thought to simply be related to an imbalance between energy intake and expenditure. Weight loss recommendations have traditionally focused on reducing energy intake, maintaining either a high-carbohydrate low-fat diet or vice versa, and increasing physical activity typically through low to moderate intensity exercise. More recently, genetic, physiological, and behavioral factors have also been found to play a significant role in the etiology of obesity. For this reason, the prevention [...] 2021 29849 |
Online Delivery of Emotional Freedom Techniques in the Treatment of Food Cravings and Weight Management: A Randomised Controlled TrialAbstract
Background: The combination of dietary restraint and physical exercise as a recommended treatment for weight loss has had limited long-term success. One factor proposed as limiting weight management techniques efficacy is the failure to target psychological processes linked with overeating. Consistent with prior research that has identified the efficacy of emotional freedom techniques (EFT) in reducing food cravings and aiding weight loss, this pilot randomised controlled trial (RCT) examined the impact of online d [...] 2219 29819 |
Electricity without FuelAbstract
Most power plants produce electricity by converting a mechanical motion into alternating current (AC). Photovoltaic solar panels convert an electromagnetic flux of light into direct current (DC). In general, electric energy can be harvested from a flux in the environment or from a change of the environment itself. One can produce electricity from mechanical, chemical, thermal, electromagnetic (light), or another physical flux, or from a change of temperature, chemical composition, or a physical field: gravitationa [...] 2314 29729 |
Evaluation of the Prevalence of Screening for Dysphagia among Older People Admitted to Medical Services – An International SurveyAbstract
Background: With the increasing age of the world population, the number of old and frail people is increasing. Respiratory disease is a common reason for hospital admission for older people. Aspiration of saliva, which is probably infected, is the likely etiological agent. The incidence of an abnormal swallow is high in frail older people. Despite the high incidence of swallow problems among older people, many hospital services do not routinely screen older people for dysphagia.
Methods: A survey, using Research El [...] 2341 29579 |
Solar Thermal Energy Stills for Desalination: A Review of Designs, Operational Parameters and Material AdvancesAbstract
The demand for high-quality freshwater is increasing due to global population growth, intensifying agricultural practices and expanding industrial development. Additionally, many global regions have low levels of rainfall which makes them arid and incapable of supporting large human populations or agriculture. Currently, large quantities of fossil fuels are used to generate the power needed to drive energy intensive desalination processes that deliver high-quality freshwater to many of these regions. However, the u [...] 2459 29502 |
Environmental and Human Health Impact of Antibiotics Waste Mismanagement: A Reviewby
Abstract
The discovery of antibiotics and their use in the last century substantially shifted the management of an array of infections. However, its unprecedented irrational usage and inept disposal of their waste exposed the ecosystems to unquantifiable antibiotic deposits, triggering the emergence of antimicrobial resistance (AMR) with its immeasurable critical risk to public health. By adopting a narrative review method and accessing the available literature, the authors described what constitutes antibiotic waste, their [...] 2866 29218 |
