3-Dimension printing (3-DPT) or additive manufacturing (AM) technology has been utilized for a while in the construction of customized 3-D objects utilizing computer software such as computer-aided design (CAD). However, the emergence of an innovative and new four-dimensional printing (4-DPT) has enabled the synergy of AM technology with programmable materials in transforming digital processes virtually into physical entities, thereby providing innovation and advanced functionalities. 4-DPT is a procedure facilitat [...]

Recurrent acute pancreatitis (RAP) is a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion. Recurrence of pancreatitis generally occurs in a setting of a normal anatomical and functional gland, however, a chronic disease at early stage may be found either on the occasion of the first episode of pancreatitis or during the follow-up. The etiology of RAP can be identified in up to 70% of cases; for the remaining cases the term “idiopathic” is used. Most common caus [...]

Various grades of cognitive impairment generally occur in older adults over the age of 55, where cardiovascular risk factors such as diabetes and/or hypertension, coronary artery disease, or cerebrovascular accidents are also common. Cognitive impairment occurs in various forms, from mild or amnesia such as forgetting today's date to more ominous and progressive forms, such as frank dementia. Over 5 million people worldwide suffer from dementia, most of whom live in low- and middle-income countries. It has been env [...]

More and more studies revealed links amongst neurological disorders, heart diseases and cancers. For example, people with subclinical cardiovascular diseases are at higher risk for Alzheimer's disease, Parkinson’s disease is associated with varied risk of cancer, Autism Spectrum Disorders and cancer have overlapping genes and molecular pathways, heart disease and cancer share common risk factors, etc. It is intriguing how are these conditions that appear to be completely different linked together.

Keratinocytes are particularly vulnerable to oxidative stress due to their function as the primary natural protective barrier exposed to chemicals, rays, and pollution to stimulate the formation of free radicals in the body. Two factors of interest correlate with cellular senescence under oxidative stress. These include regulating antioxidant synthesis, which maintains free-radical homeostasis through the Nrf2 gene, and the prevention of telomere shortening, which involves the collaboration of human telomerase gene [...]

The Coronavirus Disease (COVID-19) pandemic has contributed to a co-occurring psychiatric epidemic. Children and adolescents have been particularly impacted, with disruptions in continuity of learning and healthcare. Psychological stressors such as fear of infection, boredom, decreased socialization, supply shortages, and incomplete information have contributed to low mood, irritability, insomnia, and emotional exhaustion. Our study contributes to this research by quantifying the devastating psychiatric toll that t [...]

The increasing incidence of adult-onset dementia disorders and primarily Alzheimer’s disease (AD) among the aging population around the world is increasing the social and economic burden on society and healthcare systems. This paper presents three neural networking algorithms: MobileNet, Artificial Neural Networks (ANN), and DenseNet for AD classification based on MRI imaging data. The results of each model were compared in terms of performance metrics such as accuracy, true positive rate, and receiver operating cu [...]

The influence of cerebral amyloid angiopathy (CAA) in Alzheimer’s disease (AD) remains unexplored. The present post-mortem study investigated possible differences in the degree of hippocampal atrophy (HA) between AD patients with and without CAA using 7.0-tesla magnetic resonance imaging (MRI). Also, the incidence of the hippocampal cortical micro-infarcts (HCoMIs) and hippocampal cortical micro-bleeds (HCoMBs) is compared to those in the neocortex. The examined post-mortem brains included 30 AD-CAA cases and 20 AD [...]

Zebrafish (Danio rerio) is a vertebrate with unique characteristics, making it an excellent biomedical research animal model. One research area involves investigating changes in gene expression during neurodegenerative processes, aging-related changes, and behavioral studies in zebrafish. To achieve this, high-quality and quantity RNA must be extracted from zebrafish. This study aims to develop an optimized RNA extraction method from zebrafish larvae brains. After rearing and maintaining the zebrafish in suitable c [...]

Platelet-rich plasma (PRP) is a promising tool in regenerative medicine because it stimulates tissue repair and regeneration. PRP contains a high concentration of platelets, growth factors, and cytokines involved in the healing process. This editorial paper aims to give an overview of PRP in regenerative medicine and its potential applications in various medical fields such as orthopedics, dentistry, dermatology, and wound healing. PRP can be integrated with other regenerative therapies, such as stem cell and gene [...]
