Background: Dementia is a progressive and debilitating condition that affects millions of patients in the United States with an enormous impact on healthcare costs, caregivers, and society. Patients with dementia often experience dementia-related neuropsychiatric disturbances, commonly known as Behavioral and Psychological Symptoms of Dementia (BPSD) and more recently Neuropsychiatric symptoms (NPS) in dementia. These symptoms include verbal and physical agitation, aggression, disinhibition, affect lability, apathy [...]

Background: Studies conducted on the effectiveness of psychosocial interventions have indicated that sensory stimulation represents a promising approach to reduce the psychological and behavioral disturbances in people with dementia. Multi-sensory stimulation involves the simultaneous stimulation of multiple senses, through the use of various methods, for example, by using a variety of lights, gentle stimulating music, aromas, and tactile objects, among others. A relatively novel approach is the enriched thematic m [...]

Edible wild plants are a largely available food at no cost and an emblem of sustainability. Among the numerous varieties of edible wild plants, purslane (Portulaca oleracea L.) and common mallow (Malva sylvestris L.) are good sources of healthful bioactive compounds. Therefore, there is a growing interest in their consumption for health-related nutritional and sustainable perspectives. Fresh durum wheat tagliatelle fortified with dried and pulverized leaves of mallow or purslane at two distinct percentages of integ [...]

Background: The ketogenic diet (KD) was developed in the 1920s as a treatment for pediatric epilepsy and is emerging as a possible treatment option for certain mental health disorders. There is a link between certain mental health disorders and epilepsy, suggesting some commonality among underlying mechanisms. Methods: The literature relating to mental disorders and the KD is sparse. The authors attempt to a narrative review of the existing literature to show that there may be validity to studying the KD as a treat [...]

Silver nanoparticles have been utilized in an easy, sensitive, and effective approach through spectrophotometry and spectrofluorimetry to quantify urea in water samples. Here, 1,3-di-(1H-imidazole-1-yl) -2-propanol (DIPO) was employed to stabilize Ag NPs produced from the reduction of aqueous silver nitrate by sodium borohydride (NaBH4). Beer-Lambert's law was applied for determination using the complexation of Ag NPs with urea molecules. The results show urea can be assessed concurrently with good results and perc [...]

Exercise-induced moderation of postprandial glycaemia in adolescents is unclear and has not been examined under free-living conditions. We assessed the effect of moderate-intensity exercise (MIE) and high-intensity intermittent exercise (HIIE) bouts on subsequent postprandial glycaemic responses across three standard school days. Fourteen healthy adolescents (13 ± 1 years) completed three conditions in the following order across consecutive days: MIE, 30-min continuous brisk walking; CON, no-exercise control; HIIE, [...]

In a mammal, at the beginning of its development, the gonad is bipotential. The shift into a male or female pathway is coordinated by the sex chromosomal complement, which triggers a series of genetic pathways signaling the developmental pattern of the gonadal anlage. Being mutually exclusive, the differentiated gonad should be either a testis or an ovary. In females, the absence of SRY, a testis-determining gene, drives the signaling cascades controlling the ovarian differentiation. Albeit rare, disorders of the g [...]

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvantages of carbon deposition and sintering, so a highly efficient and robust catalyst with superior anti-deactivation properties is required. One way to meet this need is to incorporate active metals into crystalline oxides, such as perovskite. In this paper [...]

This review explores the potential of compounds derived from red algae (Rhodophyta) as promising neuroprotective agents for treating neurodegenerative disorders. Red algae, abundant in marine environments, contain bioactive compounds with diverse chemical structures and functionalities. Sulfated polysaccharides, primarily agar and carrageenans, stand out as the predominant and widely utilized compounds derived from red algae. Additionally, red algae harbor a spectrum of potential molecules such as essential fatty a [...]

Clowning has a varied tradition and a long history. Recently, clowns have been adopted in the medical setting with the aim of decreasing the negative emotions that can be experienced during hospitalization and medical procedures, as well as inducing positive feelings in patients, their relatives, and the hospital staff. Due to an increase in the number of clowns working in hospitals and the large amount of interest shown in utilizing this approach, an increasing number of studies have focused on testing the efficac [...]
