This study examined a serial mediation mechanism to test the effect of chatbots' human representation on the intention to comply with health recommendations through psychological distance and trust towards the chatbot counselor. The sample of the study comprised 385 adults from the USA. Two artificial intelligence chatbots either with human or machine-like representation were developed.

The growing demand for mental health services and artificial intelligence chatbots to replace human agents have led to increased attention to chatbot anthropomorphizing. This study explored the effect of anthropomorphism on counseling satisfaction and reuse intention for chatbot-led mental health counseling and the mediating role of social rapport in the relationship. This study also examined the interaction effect of anthropomorphism and social anxiety on counseling satisfaction and reuse intention.

This study explored the effect of chatbot emotional disclosure on user satisfaction and reuse intention for a chatbot counseling service. It also examined the independent and sequential mediation roles of user emotional disclosure intention and perceived intimacy with a chatbot on the relationship between chatbot emotional disclosure, user satisfaction, and reuse intention for chatbot counseling. In total, 348 American adults were recruited to participate in a mental health counseling session with either of the two types of artificial intelligence-powered mental health counseling chatbots.

Article Synopsis
  • Amyloid-β peptides from β-amyloid precursor protein (APP) are important in Alzheimer's disease, and cellular cholesterol levels affect their production and clearance, leading to conflicting outcomes.
  • Researchers created bigenic ANPC mice to study how cholesterol impacts APP/Aβ metabolism, finding increased levels of APP C-terminal fragments and Aβ peptides in the brains of these mice.
  • The study indicated that cholesterol sequestration disrupts the clearance of these peptides, heightens oxidative stress in certain brain regions, and may make neurons more vulnerable to toxicity, highlighting the crucial role of cholesterol in Alzheimer's disease pathology.

Renal cell carcinomas (RCCs) are frequently occurring genitourinary malignancies in the aged population. A morphological characteristic of RCCs is an irregular nuclear shape, which is used to index cancer grades. Other features of RCCs include the genetic inactivation of the von Hippel-Lindau gene, VHL, and p53 genetic-independent inactivation.

Parkinson's disease (PD) is the second leading neurodegenerative disease, and is known to be induced by environmental factors or genetic mutations. Among the verified genetic mutations of PD, Parkin, isolated from the PARK2 locus, shows an autosomal recessive inheritance pattern and is known to be an E3 ligase. However, the physiological target of Parkin and the molecular mechanism of Parkin-deficiency-induced PD have not been clearly demonstrated until now.

Genetic mutation of α-synuclein (α-SYN) is clearly verified as the causal factor of human and mouse Parkinson's disease. However, biological function of α-SYN has not been clearly demonstrated until now. In this investigation, we reveal that α-SYN is a co-regulator of growth factor-induced AKT activation.

At the neuron developmental stage, neuron-precursor cells can be differentiated into neuron or glia cells. However, precise molecular mechanism to determine the cell fate has not been clearly demonstrated. In this study, we reveal that Drosophila esgarcot and its mammalian homologue genes, Snail and Slug, play a key role in neuronal differentiation.
