For several years, cancer has increased in the population, being one of the main causes of death worldwide. This clinical pathology is associated with the activation/release of various biomolecules, including the Janus kinase family (JAKs). It is important to mention that some studies indicate that some JAK inhibitors (ruxolitinib and tofacitinib) may have a significant effect on some autoimmune diseases and cancer; however, some of these drugs can produce secondary effects such as herpes zoster, infectious, acute respiratory distress and others. The aim of this study was to evaluate the interaction of coumarin and its derivatives (compounds 2 to 24) with the JAK-3 surface. In this way, the Interaction of coumarin and their derivatives with JAK-3 was determined using the 3pjc protein and either decernotinib or tofacitinib drugs as theoretical tools on DockinServer program. The results showed differences in the aminoacid residues involved in the interaction of coumarin and their derivatives with 3pjc protein surface compared with decernotinib and tofacitinib. Besides, the inhibition constant (Ki) for coumarin derivatives 7, 9 and 10 was lower compared with tofacitinib. However, Ki was lower for 2, 5, 7, 8, 9, 10, and 24 compared with decernotinib. In conclusion, the coumarin derivatives 2, 5, 7, 8, 9, 10, and 24 could be good alternatives as JAK-3 inhibitors to decrease cancer cells growth.

With the development of current technology and influences that have been made by the Industry 4.0 utilizing ICTs, IoT, smart systems and products and many others, Assistive Technology (AT) is an important and integral part of the daily life of many people who experience disabilities. Autism Spectrum Disorder (ASD) is a special category of disorder that can greatly benefit from its use. The purpose of this research is to collect data of Assistive Technology aimed at the detection, prevention and improvement of anxiety and stress (a characteristic of which has been proven to exist and is expressed in various ways in people with ASD). In the introduction, basic definitions regarding the neurobiology of stress and ASD are analyzed. In the main part AT, stress and anxiety correlations are made with ASD and AT devices are described and documented regarding their use for anxiety and stress in children and adolescents with ASD. The Assistive equipment and devices are divided into 2 main categories, 1) Low-tech and 2) Mid-High tech. The results of the research reveal a significant research gap in the use of AT to combat stress and anxiety and the difficulty of many promising options (especially in the domain of Mid-High tech) to be an easy and economical solution in integrating them into the daily life of people with ASD.

Sensory Integration Therapy (SIT) is a widely known and used intervention by a lot of professionals and practitioners in the field of special education as being an enabler of functionality of the child. Through intervention, the sensory processing components that have been affected are targeted. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is highly affected by sensory modulation disorder (SMD), a special subcategory of sensory processing disorder (SPD) that is expressed in various ways causing activation of Autonomic Nervous System (ANS) leading to biological and physiological stress. Emotional Intelligence (EI) is a complex set of skills that drive us to higher mental states. According to theorists the basis of these skills is the ability to manage and regulate stimulus. The purpose of this literature review is to investigate the connections between SIT and EI in children with ASD. In the introduction basic definitions and concepts of ASD and SIT are analyzed and in the main part correlations between EI and SMD are made, discussing the effectiveness of SIT in ASD children.

The last century has seen an evolution in technology that has improved communication systems and, in general, made life easier for people. Our communication systems have become faster and more dependable as a result of the explosion of gadgets and services. But, these upgrades come at a price. The power consumption is one of the most worrying costs. In recent years, the solution involved installing larger, more powerful batteries—so long as doing so did not limit mobility. Today's economic and environmental problems compel us to consider alternative solutions, like methods for lowering the power consumption of digital devices. This study focuses on using digital circuits, which promise to deliver good energy efficiency and desirable performance at very low voltage savings. Certain digital switches are allegedly redundant and not required for the circuit to function properly, yet they continue to use energy. So, one of the primary issues for low power design is reducing such redundant switches. Subthreshold conduction in digital circuits is typically seen as a “parasitic” leakage in a condition where there should ideally be no conduction. Sub-threshold activities thereby reduce the problem of lowering power consumption, but do so at the expense of system throughput deterioration, fluctuations in system stability and functionality, temperature variations, and most critically, design space utilization. In order to minimize some of these redundant switches and to make circuits more energy-efficient while maintaining functionality, this study suggests two novel techniques. It uses an optimization method based on threshold voltage change to reduce glitch power. A glitch-free circuit netlist is created using an algorithm, while still maintaining the requisite delay performance. Using this approach results in a 6.14% overall reduction in energy consumption.

The installation of dental implants brings significant improvements in patient's quality of life, causing the demand for these procedures to increase. This growth results from the increasing use of innovative technologies in oral care. Since the 1970s, dental implants have continuously evolved, both in terms of shape and surface treatments. This evolution aims to improve osseointegration, an essential process for implant success, and prevent complications such as peri-implantitis. A necessary part of this evolutionary process is surface treatment on dental implants. This treatment improves implant surfaces' physical and chemical properties, promoting a more efficient interaction between the implant and surrounding tissues. To achieve this goal, modifications are made to the texture, composition, and characteristics of the implant surface. In this context, this study aims to identify the research gaps related to surface treatment on dental implants. To this end, a literature review was performed in the Scopus database using specific search terms related to this topic. The 20 most cited articles from 2017 to 2023, which address the main research trends in this area, were selected for analysis. The theoretical contribution of this study is to systematize the current research trends on the surface treatment of dental implants. This provides a better understanding of existing treatments and their limitations and presents ongoing studies that aim to overcome them. Furthermore, the research highlights studies under development, both in vitro and in vivo, that seek to apply scientific advances in clinical practice to improve implant outcomes. This applied contribution is relevant, as it can positively impact clinical practice and benefit patients.

This work aimed to evaluate the interaction between P-solubilizing microorganisms and organomineral fertilizers in order to increase the cowpea nutrition and yield under field conditions. One field trial was carried out in a randomized complete block design arranged in subdivided plots (7 x 3) with four replicates. The organominerals (poultry litter, swine manure, filter cake and soot from chimneys) as well as triple superphosphate (TSP) with and without sulfur and the control treatment (no fertilizer addition), were considered the primary factor. The secondary factor was constituted by inoculation of Bradyrhizobium sp. SEMIA 6462 (Simbiose Nod Caupi®), one P-solubilizing bacteria (MBSF2) as well as no inoculation treatment. The MBSF2 inoculation combined to the soot organomineral increased the shoot length at 50 DAE. The stem diameter, shoot and root dry matter at 50 DAE were increased by Bradyrhizobium spp. inoculation and poultry litter. Also, the stem diameter was increased using filter cake organomineral and both inoculants. The nodules number was also increased by use of that organomineral combined to Bradyrhizobium spp.

Pollen is a product originating from the anthers of flowers. Members of the Apidae group feed on this floristic product, which is metabolized and stored in the hives. It is known that the pollen metabolized by stingless and stingless bees has medicinal and nutritional characteristics. This study aimed to evaluate the physicochemical and microbiological quality of pollen collected by Tetragonisca angustula, Melipona quadrifasciata and Apis mellifera. Pollen was collected between January 2021 and January 2023 in a conservation area in Goiás, Brazil. The pollen was characterized by physicalchemical analysis for moisture, ash, proteins, lipids, total sugars and pH, and microbiological analysis on Escherichia coli and Salmonella spp. The obtained results characterize the pollens of indigenous bees as suitable for consumption, since they presented good physicochemical characteristics for most of the analyzed parameters and free of pathogens.

This study aimed to evaluate the propolis of Tetragonisca angustula regarding its classification group, ultraviolet and visible spectroscopy (UV-Vis) and its antifungal biological activity against Sclerotinia sclerotiorum, Colletotrichum gloeosporioides and Colletotrichum acutatum phytopathogens of grains and fruits of interest commercial. Propolis was collected from T. angustula hives in a permanent preservation area. The ethanolic extract was produced by static maceration. The classification group according to the dermal color, the determination of the bands were obtained in a UV-Vis spectrophotometer between 450-800 nm, the antifungal activity carried out in in vitro PDA medium at different concentrations on S. sclerotiorum, C. gloeosporioides and C. acutatum and expressed as a percentage (%).
