Since 1907, when Bakelite was invented, there has been a dramatic rise in the daily usage of plastic-like materials. Today, its negative impacts are a part of scientific studies and public debates. Art and artists play a significant role in these discussions. They mediate between the specialist content and public awareness. This study is dedicated to the artworks of artists using plastic waste collected from the seashore. I organized their works into three lines, within which artists have different threads of plast [...]

Background: Research has shown that positive psychology interventions can enhance subjective well-being and reduce depression. However, the efficacy of these programs with older adult populations has been minimally studied. The present study studied the short and long term impact of an intervention enhancing happiness and overall mental well-being in older adults. Methods: The Art of Happiness is an 8-week program conducted at 2 senior centers in the state of Delaware. Each 90-minute class examined a different topi [...]

Photobiomodulation (PBM), as well as plant extracts of Calendula officinalis (Calen), Hypericum perforatum (Hyper), and Echinacea purpurea (Echi-p), have been used to accelerate wound healing. However, the use of homeopathic preparations of these medicinal plants, in combination with PBM, is unknown. The objective of this study was to investigate the combined wound healing potential of these therapies in vitro. Various cell models were created in vitro in commercially available human skin fibroblasts (WS1). PBM was [...]

Gait speed has been correlated to quality of life and has been called the sixth vital sign. The purpose of this study was to understand the factors that comprise fast and comfortable gait speed. 90 older adults provided demographic, cognitive, and functional performance data. Hierarchical linear regression models revealed predictors for comfortable gait speed to be lower-extremity strength ( B = 1.13, β = 0.233, P< .05), comorbid health ( B = −2.95, β = −0.22, P < 0.05), and gender( B = [...]

In AC microgrid systems, technical issues resulting from the power control effect are the power control method efficiency and the filter resonance since voltage-frequency interference and filtering resonance may cause significant control input reduction and oscillation. A simple and robust solution is to regulate active power flow by adding an optimal passive damping resistor. The optimal LCL filter parameterization process in this paper provides an innovative approach to obtain the optimal quality factor and the o [...]

One-pot synthesis of mesoporous hybrid material consisting of Mn-Co/CoO nanoparticles encapsulated in an N-doped graphene shell decorated with Mo2C nanoparticles (Mo2C-NC@Mn-Co/CoO) was reported. The Mn and Mo components synergistically refined the graphitized carbons due to the interactions with N and C atoms while promoting the stability of the Co/CoO nanoparticles. These components exhibited a beneficial effect on the dispersion of the active metal/metal oxide nanoparticles and the formation of a mesoporous stru [...]

Insulin-like growth factor 2 (IGF2) is a strong mitogenic peptide with an imprinted gene that is primarily involved in fetal development. It is highly expressed in the fetus where it is involved in fetal growth and tissue differentiation. However, postnatally, the expression of IGF2 decreases despite higher expression levels in the blood as compared with that of IGF1. In adults, the physiological function of IGF2 is poorly understood; however, the possibility of a metabolic function exists. Although the expression [...]

Phytotherapy, which is defined as the use of titrated herbal extracts in clinical practice, has been receiving increasing interest in the scientific community recently. In the present report, information regarding the most important mechanisms underlying the drug-drug interactions (DDI) and herb-drug interactions (HDI) has been discussed briefly. Furthermore, the best known and relevant interactions of Ginkgo biloba, Citrus paradisi (Grapefruit Juice), Silybum marianum (Milk Thistle), Hypericum perforatum (St. John [...]

The consistent associations between dampness and health-related problems, such as allergies and asthma symptoms, explain the growing scientific interest in assessing housing characteristics. Due to a growing interest in the built environment, the present study performed a systematic review to investigate the prevalence of dampness related to specific building characteristics. The built environment is gaining significance in population well-being due to the substantial time spent indoors. This aspect is especially n [...]

In recent years, research on converting biomass platform compounds into high-value chemicals and pharmaceutical intermediates has garnered huge interest. Nitrile and amide groups are key structures in natural products and biologically active molecules. The direct conversion of biomass platform compounds into nitriles and amides will undoubtedly be an important guide for biomass utilization. In this paper, a facile and efficient triphosgene-assisted one-pot conversion for aldehydes and ketones into nitrile and amide [...]
