Technological development made in the field of biomass application allows synthesizing several high-value products, such as furfuraldehyde. Furfural, produced through sequential hydrolysis and dehydration reactions from biomass, is considered a platform molecule and a precursor of several other chemicals and biofuels that are generated following reactions such as hydrogenation, hydrodeoxygenation, and decarboxylation. This review aims to reveal the environmental-friendly mechanisms followed for producing furfural d [...]

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 [...]

Studies in the field of neuroscience have shown that the neural network responsible for numeracy overlaps with the visual and spatial processing regions. Other studies in psychology also highlighted an association of visual-spatial processing with mathematical competence at the early stages of development. These findings suggest that research on the size of the focal area of attention (consciousness) can contribute to understanding the development of numeracy. In this case study, we verified the hypothesis of devel [...]

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: The 2018 Alzheimer's Disease Facts and Figures special report includes two new guidelines for measuring dementia symptoms. The first requires that a biomarker (biological factor) be added to a doctor's clinical judgment of the cause of symptoms when determining whether dementia is present. The second involves identifying four stages of dementia: normal cognition, preclinical, MCI and dementia. Now only those with defining brain pathologies and significant symptoms will be judged to be persons with stage [...]

This article aims to analyze how Western researchers can be influenced by their epistemic and ethical foundations, which are also expressed through a culturally shared idea of therapy, and how this influence can significantly hinder the understanding of a different cultural reality and its resources in terms of knowledge and practices. While examining a collection of research cases in the field of psychedelic therapy, the present paper focuses on the obstacles created by ethical and epistemic conflicts in the mind [...]

Background: Fluorescence In Situ Hybridization (FISH) has become routine for bio-medical research and medical diagnosis, thereby offering a variety of probes and ready-to-use kits that fulfil requirements for many applications. However, conventional FISH relies on chemical and/or thermal denaturation to improve target accessibility and uses huge amounts of DNA that needs to be bonded to the target site. COMBinatorial Oligo-nucleotide FISH (COMBO-FISH) offers possibilities to circumvent these shortcomings. Methods: [...]

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 [...]

Social support has been shown to have many positive effects on our lives, health, and ability to grow and flourish. Lack, or diminished social support results in loneliness. This thematic review focuses on the elderly, and the loneliness that is part of the life of many of them. The review highlights the social connections and the expectations that the elderly may have of them, and how being connected to others may alleviate, loneliness. Loneliness is known to negatively affect one’s health, social life, familial r [...]

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 [...]
