It is necessary to ensure functional diagnosis and auditory rehabilitation as part of a continuous and inseparable follow-up process that begins with Neonatal Hearing Screening to achieve the expected outcome in children with hearing loss. Different software controls the data of this process, adopting different strategies and involving the technology for this. However, there is no specific model available in the literature for analyzing the quality of the software aimed at recording and monitoring data from Neonatal Hearing Screening.

To propose a specific model for the analysis of the quality of softwares used for monitoring Neonatal Hearing Screening data, based on the ISO/IEC 25,010/2011 standards.

This is an applied research, in which a model was proposed, applied and evaluated to analyze the quality of Neonatal Hearing Screening softwares, based on an exploratory documental analysis of softwares related to the Neonatal Hearing Screening record domain. The quality model was proposed based on the ISOsider, in each country, the socioeconomic and health context to validate its applicability.

The quality model presented in this article introduced important general and specific criteria to analyze softwares for Neonatal Hearing Screening. this website This model has been validated by specialists in informatics and audiology. Therefore, this model can be used comprehensively, as a standard assessment tool for Neonatal Hearing Screening softwares, allowing predicting improvements. It is suggested that the audiologists and informatics responsible for softwares of this nature, consider, in each country, the socioeconomic and health context to validate its applicability.It is usually held that good-quality models for the biological activity of peptides must take into account their 3D architecture and descriptors of quantum mechanics. However, the present study shows that it is possible to build up models without these complex calculations. The structure of tripeptides represented by sequences of one-symbol abbreviations of the corresponding amino acids serves to build up quantitative structure-activity relationships for the antioxidant activity of tripeptides from frog skin. The statistical quality of the best model for the validation set is n = 27, r2 = 0.93, RMSE = 0.15.Cell-penetrating peptides (CPPs) have been attracting attention as tools for intracellular delivery of membrane-impermeant functional molecules. Among the variety of CPPs that have been developed, many are composed of both natural and unnatural amino acids. We previously synthesized α,α-disubstituted α-amino acids (dAAs) containing a five-membered carbocyclic ring in its side chain and revealed the utility of dAAs for the development of novel CPPs. In the present study, we designed a six-membered carbocyclic ring dAA with an amino group on the ring and introduced it into arginine (Arg)-rich peptides to further investigate the value of dAAs for developing CPPs. We also assessed the effects of the size of the dAA carbocyclic ring on cellular uptake of dAA-containing peptides. The stability of the peptide's secondary structure and its membrane permeability were both greater in dAA-containing peptides than in an Arg nonapeptide. However, the number of carbon atoms in the dAA side chain ring had little effect. Nevertheless, these results show the utility of cyclic dAAs in the design of novel CPPs containing unnatural amino acids.Xanthine oxidase is the rate-limiting enzyme critical for the synthesis of uric acid, and therefore xanthine oxidase inhibitors are considered as one of the promising therapies for hyperuricemia and gout. In our previous study, series of 2-(4-alkoxy-3-cyano)phenyl-6-oxo-1,6-dihydropyrimidine-5-carboxylic acids and 2-(4-alkoxy-3-cyano)phenyl-6-imino-1,6-dihydropyrimidine-5-carboxylic acids were synthesized that presented excellent in vitro xanthine oxidase inhibitory potency. Interestingly, molecular docking studies revealed that the interaction behavior of these compounds with xanthine oxidase was changed after the conversion from a hydroxy group to amine group. To further investigate the structure-activity relationships of these pyrimidine-containing xanthine oxidase inhibitors and explore the contribution of amino or hydroxy group on xanthine oxidase inhibitory potency, several 2-phenylpyrimidine derivatives with amino or hydroxy functional group were designed and synthesized. Thereafter, the structure-activity research and molecular modeling study proved that hydroxy and amino groups could be used as pharmacophore elements for the design of 2-phenylpyrimidines xanthine oxidase inhibitors. Particularly, the optimized compound, 2-(3-cyano-4-isopentoxy)phenylpyrimidine-4-ol, emerged the strongest xanthine oxidase inhibitor potency, with an IC50 value of 0.046 µM, which was approximately 120-fold more potent than that of allopurinol (IC50 = 5.462 µM). Additionally, Lineweaver-Burk plot analysis revealed that the optimized compound acted as a mixed-type inhibitor. Furthermore, the in vivo hypouricemic effect of the optimized compound was investigated in a hyperuricemia rat model induced by potassium oxonate, and the results showed that the optimized compound could effectively reduce serum uric acid levels at an oral dose of 30 mg/kg.Beetroot is well known for its deep red-purple colouring pigments called betalains. Betalains also found its application in the preparation of functional foods and drinks. Therefore, extraction of pigments with higher recovery and stability is the prime need for the industry. Conventional extraction techniques such as maceration, grinding or pressing have reported low yield of betalains and required large volume of solvent and energy. On the other hand, emerging technologies such as ultrasound, microwave and pulse electric field techniques are highly efficient processes and can achieve higher recovery. In this regard, this review provides an in-depth discussion on the various extraction methods and factors affecting the stability of betalains using conventional and emerging technologies. The recent applications of pigments in various food systems are also presented. Finally, challenges and future prospects of extraction and application of beetroot pigment have been identified and discussed.The effects of NaCl and its partial substitutes (KCl, MgCl2 and CaCl2) on solubility, structural characteristics and aggregation behaviors of myofibrillar protein (MP) from pearl mussel muscle were investigated and compared. MP at 0.6 M NaCl was beneficial to protein unfolding and showed excellent potential functional properties. When NaCl was substituted in low level, MPs also showed good solubility and ordered microstructure as well as NaCl, especially MgCl2 and CaCl2, due to the unfolding of α-helical structures and subsequently exposed tyrosine residues and hydrophobic groups. However, the obviously increased disulfide bonds and hydrophobic interactions in high substitution level indicated the excessive non-sodium salts had negative effects on molecular rearrangement, leading to irregular and overly tight of microstructure. link2 Thus, NaCl partially substituted by KCl, MgCl2 and CaCl2 in low substitution level is promising to improve functional properties of MP in low-sodium meat products.The purpose of this umbrella review was to evaluate the quality of evidence, validity and biases of the associations between red and processed meat consumption and multiple cancer outcomes according to existing systematic reviews and meta-analyses. The umbrella review identified 72 meta-analyses with 20 unique outcomes for red meat and 19 unique outcomes for processed meat. Red meat consumption was associated with increased risk of overall cancer mortality, non-Hodgkin lymphoma (NHL), bladder, breast, colorectal, endometrial, esophageal, gastric, lung and nasopharyngeal cancer. Processed meat consumption might increase the risk of overall cancer mortality, NHL, bladder, breast, colorectal, esophageal, gastric, nasopharyngeal, oral cavity and oropharynx and prostate cancer. Dose-response analyses revealed that 100 g/d increment of red meat and 50 g/d increment of processed meat consumption were associated with 11%-51% and 8%-72% higher risk of multiple cancer outcomes, respectively, and seemed to be not correlated with any benefit.This study aimed to assess the effects of acetylation levels on actomyosin disassociation and phosphorylation of lamb during incubation at 4 °C. Samples of whole proteins from lamb longissimus thoracis muscles were prepared and assigned into three treatments (high, middle and low acetylation groups). The results showed that deacetylation of myosin heavy chain and actin was inhibited by lysine deacetylase inhibitor trichostatin A and nicotinamide in this study. link3 Phosphorylation levels of myosin heavy chain and actin were inhibited by their acetylation during incubation in vitro. Actomyosin disassociation degree in high acetylation group was significantly lower than that in middle and low acetylation groups (P less then 0.05). The ATPase activity in high acetylation group was significantly higher than that in middle and low acetylation groups (P less then 0.05). In conclusion, acetylation of myosin heavy chain and actin inhibited actomyosin dissociation by inhibiting their phosphorylation at 4 °C in vitro.A novel fluorescent probe (RA), based on the rosamine skeleton bearing acrylate group, has been reasonably designed and prepared, which employed an addition-cyclization-elimination sequence reaction mechanism to detect cysteine. RA displayed rapid response to cysteine within 1.5 min, and exhibited satisfactory selectivity for cysteine over H2S, glutathione (Glu), and homocysteine (Hcy), due to the formation of seven-membered lactam favored kinetically. Fluorescence ratio was utilized to detect cysteine from 6.0 to 20.0 μM with a detection limit of 0.29 μM. More, RA was used to monitor cysteine in BSA, water, milk, milk powder, cabbage, radish, apple, and pear.This work aims to describe the purification and characterization of acidic-hydrolyzed corn silk polysaccharides (AH-CSP) and evaluate their protection on the H2O2-injured intestinalepithelial cells (IEC-6). Two fractions named AHP-1 and AHP-2 were obtained from AH-CSP, and physicochemical properties of them were investigated by gel permeation chromatography (GPC), gas chromatography (GC), nuclear magnetic resonance (NMR), fourier transform infrared (FT-IR) spectroscopy, scanning electronic microscopy (SEM), and Congo red test. Results showed that AHP-1 (2.80 × 104 Da) and AHP-2 (1.25 × 104 Da) were consisted of xylose, mannose, galactose, rhamnose, arabinose, and glucose. AHP-1 and AHP-2 had strong scavenging activities on 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-Azobis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), and OH· free radicals. Furthermore, pretreatment with AHP-2 could protect the H2O2-injured IEC-6 cells by effectively scavenging the overproduced reactive oxygen species (ROS) and regulating of Kelch-like ECH-associated protein 1(Keap1)/ nuclear factor erythroid 2-related factor 2 (Nrf2) signal pathway.Multi-agent deep reinforcement learning (MDRL) has been widely applied in multi-intersection traffic signal control. The MDRL algorithms produce the decentralized cooperative traffic-signal policies via specialized multi-agent settings in certain traffic networks. However, the state-of-the-art MDRL algorithms seem to have some drawbacks. (1) It is desirable that the traffic-signal policies can be smoothly transferred to diverse traffic networks, however, the adopted specialized multi-agent settings hinder the traffic-signal policies to transfer and generalize to new traffic networks. (2) Existing MDRL algorithms which are based on deep neural networks cannot flexibly tackle a time-varying number of vehicles traversing the traffic networks. (3) Existing MDRL algorithms which are based on homogeneous graph neural networks fail to capture the heterogeneous features of objects in traffic networks. Motivated by the above observations, in this paper, we propose an algorithm, referred to as Inductive Heterogeneous Graph Multi-agent Actor-critic (IHG-MA) algorithm, for multi-intersection traffic signal control.
