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 [...]

Transplantation is a widely accepted and successful life-saving treatment for hundreds of thousands of patients. However, transplant medicine still faces a number of obstacles. One of the most significant is the large disparity between the number of donors and recipients and the growing need for re-transplantation. In the last two decades, the improvement and organization of the national transplantation program in Croatia have resulted in a steadily increasing donor rate and therefore the transplantation numbers. A [...]

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 [...]

1-Decylbenzimidazole (dbim) copper(II) complexes formed during solvent extraction were thoroughly studied, and their structures were predicted. Density functional theory (DFT) calculations of their structures and Time-dependent DFT (TD-DFT) calculations of their spectra indicated that 1-decylbenzimidazole forms both mono- and binuclear complexes with copper(II), with coordination numbers of 4 or 5. At the molar ratio of [Cu(II)]aq/[dbim]org ≥ 1 and at [Cl-]aq ≥ 0.9 mol dm-3 in the extraction media, a binuclear 1:1 [...]

We present a case of a 74-year-old woman with deep intracerebral hemorrhage (ICH), probable cerebral amyloid angiopathy (CAA), and probable antiphospholipid syndrome (APS). Due to the high hemorrhagic risk, it was decided not to use anticoagulants. In a period of three months, she had two separate cerebral ischemic events and died of stroke-related complications. The use of oral anticoagulation (OAC) in this patient is neither supported nor contra-indicated by current literature, even though past medical history su [...]

Acupuncture, an ancient practice in traditional Chinese medicine, is founded on understanding of human physiology and the dynamics of energy flow (Qi). The emergence of artificial intelligence (AI) in modern medicine presents opportunities to integrate advanced technologies into acupuncture, enhancing diagnostic precision and empirical validation. AI tools can analyze complex datasets, model energy flow dynamics, and provide evidence-based insights, potentially bridging traditional methodologies with scientific par [...]

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 [...]

This work aimed at evaluating all products from the low-temperature pyrolysis (350°C) of some industrial wastes, cotton stems and seeds (CSS), grape husks and curls (GRH), undigested sewage sludge (USS) and their blends in a fixed bed system and suggesting their possible applications. Solid and liquid products, biochars, and bio-oils were analyzed using various techniques by physicochemical, mineralogical, and chemical analyses. Gases were qualitatively and quantitatively analyzed using a thermogravimetric-mass [...]

Wheelchair basketball (WB) is a health and inclusion opportunity for people with disabilities. In the scientific literature, no evidence defines WB as a symmetrical or asymmetrical sport; however, it would be helpful to deepen this aspect because it could improve the quality of training programs and consequently speed up WB performance. In WB, the biomechanical role of the shoulders is crucial. Therefore, the symmetry index and the activation of the bilateral supraspinatus and biceps brachii muscles were investigat [...]

Worldwide, human population growth has led to a higher demand for urbanization. While this development is in accordance with our gregarious lifestyles, our availability and contact with nature has consequentially been minimized. The goal of this study was to evaluate whether sounds from nature versus urban environments affect vital signs (i.e., heart rate and respiration rate) and mood states of female college students. Emotional states were assessed using the Positive and Negative Affect Schedule (PANAS) questionn [...]
