A literature survey shows that the valorization of urban and/or agricultural biowastes into chemicals has caught the attention of experts and is gradually becoming quite an important issue. This review presents the application of the Bio-Based Substances (BBS) isolated from the compost of bio-wastes from urban gardening and park trimming residues. The non-cost BBS has been well studied in the literature. BBS are biological macromolecules with a complex lignin-derived structure containing several functional groups, [...]

Nontuberculous mycobacteria (NTM) infections are relatively rare but carry significant morbidity in solid organ transplant (SOT) recipients. Given the rarity of disease and diagnostic limitations, a high index of suspicion is required for accurate diagnosis and initiation of appropriate treatment. We discuss the challenges in diagnosis and management of NTM infections specific to the SOT population.

Immunoglobin A Nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. Its development is characterized by the deposition of immune complexes that consist of abnormally galactosylated IgA1 molecules and IgG or IgA autoantibodies in the mesangium and the subsequent induction of renal injury. Recent research has shed light to many aspects of the pathogenesis of the disease, including the contribution of epigenetic modifications in its onset and progression. This review aims to present some of the [...]

Background: Qigong, traditional Chinese mind-body practices, is currently receiving increasing attention with exploration of what it is and what it does. Common elements include postures and movement, attention to breathing, and mental instructions. There is a growing literature on the health benefits of qigong in chronic pain and other conditions, and an intervention that provides benefit in multiple domains is particularly important for clinical practice. In this report, we present a case series of six individual [...]

Food insecurity and insufficient access to affordable nutrition have been associated with increased risk for the development of multiple chronic medical conditions, including cardiovascular disease. In this narrative review, we explore the association between food insecurity and the development of chronic medical conditions that confer increased cardiometabolic risk, cardiovascular disease, and mortality. We also identify the various barriers leading to food insecurity and lack of food literacy, with an emphasis on [...]

In this paper, due to the importance of energy recovery from internal combustion engines and the increasing human growing need for power and refrigeration, a two-cycle power and refrigeration system consisting of an organic Rankine cycle and an ejector refrigeration cycle is investigated analytically. The proposed system with the ability to use the ejector as an effective and economical system, can produce simultaneous power and refrigeration by drawing thermal energy from the exhaust gas and engine coolant in the [...]

The current study aimed to examine if sex can significantly predict risk for lifetime major depressive episodes among adults aged 65 and older with and without adjustment for covariate variables of race, education, marital status, health, and poverty. Secondary data was obtained from the National Survey on Drug Use and Health public-use data file to achieve study goals. The study participants were males and females aged 65 years or older. The unweighted sample included 3,969 adults aged 65 years or older, represent [...]

Coronary artery disease is one of the major causes of morbidity and mortality worldwide. Coronary stents, tube-shaped medical implants that are placed in narrowed coronary arteries, have been used successfully in the management of this condition. However, re-narrowing (i.e. restenosis) of the artery can occur which is instigated by an immune response towards the implanted ‘foreign’ material. A new approach to prevent restenosis and reduce the stent-induced immune response has been proposed previously, which involve [...]

As wind turbine blades grow longer, new design parameters gain additional importance such as blade weight, tip deflection and material cost. These parameters require designers to relook at carbon fiber as a potential design solution. However, the composite materials in wind turbine blades are subjected to significant compressive loading, and the compressive strength of carbon fiber reinforced polymer (CFRP) composites is much lower than its tensile strength. This reduction in compression strength is due to a change [...]

This research study addresses certain theoretical issues surrounding the relationship between digital technologies, the aging population, and identity. At the same time, it offers a conceptual proposal of indicators of the social inclusion of older people in the digital culture of society as a potential starting point for further empirical research. The progressive trend of a growing proportion of older people is a demographic reality in many economically and technologically advanced societies. This demographic agi [...]
