This study employs electroencephalography (EEG) to assess the efficacy of a person-centered communication intervention in the context of dementia care. Seventy-seven individuals in the early stage of dementia, attending day care centers, were divided into experimental and control groups following a non-equivalence control design. The communication intervention consisted of 30 minutes of semi-structured, topic-specific in-person interactions, incorporating elements of self-introduction, rapport-building, emotional exploration, reminiscence, and cognitive stimulation.

In the treatment of Alzheimer's disease (AD), traditional 40Hz gamma wave stimulation, while effective in improving cognitive function, has been limited by the lengthy duration of treatment. To address this, our study sought to enhance the time efficiency of 40Hz stimulation by utilizing intermittent theta-burst stimulation (iTBS) as a pretreatment. Experiments were conducted on AD mouse models, divided into four groups: no stimulation, 40Hz stimulation only, iTBS stimulation only, and combined iTBS and 40Hz stimulation.

Background: Electroencephalography (EEG) is a non-intrusive technique that provides comprehensive insights into the electrical activities of the brain's cerebral cortex. The brain signals obtained from EEGs can be used as a neuropsychological biomarker to detect different stages of Alzheimer's disease (AD) through quantitative EEG (qEEG) analysis. This paper investigates the difference in the abnormalities of resting state EEG (rEEG) signals between eyes-open (EOR) and eyes-closed (ECR) in AD by analyzing 19- scalp electrode EEG signals and making a comparison with healthy controls (HC).

Renal cell carcinoma (RCC) is considered as a "metabolic disease" due to various perturbations in metabolic pathways that could drive cancer development. Glycine decarboxylase (GLDC) is a mitochondrial enzyme that takes part in the oxidation of glycine to support nucleotide biosynthesis via transfer of one-carbon units. Herein, we aimed to investigate the potential role of GLDC in RCC development.

Background: While early intervention in psychosis (EIP) programs have been increasingly implemented across the globe, many initiatives from Africa, Asia and Latin America are not widely known. The aims of the current review are (a) to describe population-based and small-scale, single-site EIP programs in Africa, Asia and Latin America, (b) to examine the variability between programs located in low-and-middle income (LMIC) and high-income countries in similar regions and (c) to outline some of the challenges and provide recommendations to overcome existing obstacles.
Methods: EIP programs in Africa, Asia and Latin America were identified through experts from the different target regions.

Soil contamination with toxic heavy metals [such as aluminum (Al)] is becoming a serious global problem due to the rapid development of the social economy. Although plant growth-promoting rhizo-bacteria (PGPR) are the major protectants to alleviate metal toxicity, the study of these bacteria to ameliorate the toxic effects of Al is limited. Therefore, the present study was conducted to investigate the combined effects of different levels of (5 ppm and 10 ppm) of accession number of MT123456 on plant growth and biomass, photosynthetic pigments, gas exchange attributes, oxidative stress and response of antioxidant compounds (enzymatic and nonenzymatic), and their specific gene expression, sugars, nutritional status of the plant, organic acid exudation pattern and Al accumulation from the different parts of the plants, which was spiked with different levels of Al [0 µM (i.

Robotic systems rely on spatio-temporal information to solve control tasks. With advancements in deep neural networks, reinforcement learning has significantly enhanced the performance of control tasks by leveraging deep learning techniques. However, as deep neural networks grow in complexity, they consume more energy and introduce greater latency.

The rise in individuals living alone in ageing societies raises concerns about social isolation and associated health risks, notably lonely deaths among the elderly. Traditional electrocardiogram (ECG) monitoring systems, reliant on intrusive and potentially irritating electrodes, pose practical challenges. This study examines the efficacy of conductive textile electrodes (CTEs) vis-á-vis conventional electrodes (CEs) in ECG monitoring, along with the effect of electrode positioning.

Unlabelled: With the advent of robot-assisted surgery, user-friendly technologies have been applied to the da Vinci surgical system (dVSS), and their efficacy has been validated in worldwide surgical fields. However, further improvements are required to the traditional manipulation methods, which cannot control an endoscope and surgical instruments simultaneously. This study proposes a speech recognition control interface (SRCI) for controlling the endoscope via speech commands while manipulating surgical instruments to replace the traditional method.

Demand for user authentication in virtual reality (VR) applications is increasing such as in-app payments, password manager, and access to private data. Traditionally, hand controllers have been widely used for the user authentication in VR environment, with which the users can typewrite a password or draw a pre-registered pattern; however, the conventional approaches are generally inconvenient and time-consuming. In this study, we proposed a new user authentication method based on eye-writing patterns identified using electrooculogram (EOG) recorded from four locations around the eyes in contact with the face-pad of a VR headset.

Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.

Atopic dermatitis (AD) is a prevalent, persistent inflammatory skin disorder distinguished by pruritic and irritated skin. Toll-like receptors (TLRs) are specialized receptors that recognize specific patterns associated with pathogens and tissue damage, triggering an innate immune response that protects the host from invading pathogens. Previously, it was demonstrated that intradermal injection of the humanized anti-TLR2 monoclonal antibody (Ab) Tomaralimab effectively relieved AD-like skin inflammation in BALB/c mouse models exposed to house dust mite extracts.

Angiogenesis is mediated by vascular endothelial growth factor (VEGF), a protein that plays a key role in wound healing, inflammatory diseases, cardiovascular processes, ocular diseases, and tumor growth. Indeed, modulation of angiogenesis represents a potential approach to treating cancer and, as such, therapeutic approaches targeting VEGF and its receptors have been widely investigated as part of the broader search for curative interventions. Equally, RNA interference is a powerful tool for treating diseases, but its application as a disease treatment has been limited in part because of a lack of efficient small interfering RNA (siRNA) delivery systems.
