Feasibility study of magnetic sensing for detecting single-neuron action potentials
Authors: Denis Tonini , Kai Wu , Renata Saha , Jian-Ping Wang
Published: October 2022

Understanding the magnitude of the local magnetic fields generated by neurons is critical to assessing the feasibility of novel magnetic field sensors to record in vivo neuronal activities at cellular resolution. However, the strength of the magnetic fields induced by individual neurons and neuronal networks has not been systematically studied. This step is critical for evaluating and benchmarking the ability of different magnetic field sensors to record neuronal activities with far better spatial and temporal resolution. Herein, FEM exemplary models and open-source computational libraries are used to calculate the magnetic fields generated by individual neurons and neuronal networks at micrometer distances. Our theoretical results show that the magnetic field generated by a single-neuron action potential can be detected by ultra-high sensitivity sub-pT magnetic field sensors, which opens the door to future in vivo decoding of neuronal activities through custom neural networks. We anticipate that the identification of single-neuron signals with high-sensitivity magnetic devices will allow the interface of nanoscale devices to interpret biological signals supported by machine-learning techniques capable of monitoring and predicting the localized activities underlying brain computations.

Failure Evaluation of Reinforced Concrete Beams Using Damage Mechanics and Classical Laminate Theory
Authors: Lima José Mário Feitosa , Santos Geraldo José Belmonte dos , Lima Paulo R. L.
Published: October 2022

The prediction of the behavior of reinforced concrete beams under bending is essential for the perfect design of these elements. Usually, the classical models do not incorporate the physical nonlinear behavior of concrete under tension and compression, which can underestimate the deformations in the structural element under short and long-term loads. In the present work, a variational formulation based on the Finite Element Method is presented to predict the flexural behavior of reinforced concrete beams. The physical nonlinearity due cracking of concrete is considered by utilization of damage concept in the definition of constitutive models, and the lamination theory it is used in discretization of section cross of beams. In the layered approach, the reinforced concrete element is formulated as a laminated composite that consists of thin layers, of concrete or steel that has been modeled as elasticperfectly plastic material. The comparison of numerical load-displacement results with experimental results found in the literature demonstrates a good approximation of the model and validates the application of the damage model in the Classical Laminate Theory to predict mechanical failure of reinforced concrete beam. The results obtained by the numerical model indicated a variation in the stress–strain behavior of each beam, while for under-reinforced beams, the compressive stresses did not reach the peak stress but the stress–strain behavior was observed in the nonlinear regime at failure, for the other beams, the concrete had reached its ultimate strain, and the beam’s neutral axis was close to the centroid of the cross-section.

Aim: To investigate the in vitro structure-activity relationship (SAR) of a range of tetrahydrocannabinolic (THCA) and cannabidiolic (CBDA) derivatives using the PANC-1 tumor cell line (pancreas, ductal carcinoma). Materials and methods: The in vitro effects of a range of THCA and CBDA derivatives with different carbonyl group substituents were tested on the PANC-1 cells cell line using the CellTiter Glo Viability Assay (72 hours) and the XTT assay (48 hours). Results: A study of a series of THCA and CBDA derivatives containing different functional groups at the carbonyl nitrogen atom demonstrated that THCA amides have better inhibitory activity, on the PANC-1 tumor cell line, than CBDA derivatives. Conclusions: THCA derivatives have better inhibitory activity than CBDA analogs with the same substituents. It is noteworthy that even a slight change in the structure of the substituent of the amide or hydrazone moiety of the molecule has a dramatic effect on the activity of these compounds.

Published: October 2022

At present, the prevention of sudden cardiac death in athletes is of great interest. A large amount of literature data concerning the correlation between the length of the QT interval and the proarrhythmic potential of the myocardium has been accumulated. However, new potential predictors of the fatal arrhythmias occurrence in athletes have emerged in recent years — an increase in the dispersion of the QT interval, as well as short-term variability in repolarization. This review provides detailed data on the diagnosis, prevalence, classifi cation, etiology of long QT as one of the manifestations of QT variance. The variety of causes leading to long QT syndrome (LQTS) causes diffi culties in the diff erential diagnosis of this condition and, and as a result, LQTS often remains outside the attention of practitioners. The data of recent studies of the athlete’s heart remodelling are presented as well.

People's purchasing power for animal protein has decreased and has shifted to processed soy foods as one of the foods containing vegetable protein during the Covid-19 pandemic due to the economic recession. Soybeans are a source of high vegetable protein so they require a lot of Nitrogen (N). To fulfill the demand for soybeans, soybean cultivation can be carried out in acidic mineral soils with a low pH. Acidic mineral soil with a low pH causes it difficult for N nutrients to be available and the bacteria Bradyrhizobium sp. difficult to symbiosis with soybean plants. The aim of this study was to increase the growth and N uptake of soybean plants on acid mineral soils by inoculating Bradyrhizobium sp. and lime. The research was conducted in Jati Kesuma Village, Namorambe, Deli Serdang on a plot size 200 x 200 cm using a factorial randomized block design (RAK) with 2 factors. The first factor was the inoculating of Bradyrhizobium sp inoculants consisting of without inoculant; BGR 3 inoculant; and LP 3 inoculant. The second factor was liming consisting of without liming and liming with a dose of 1.06 kg/plot (pH 4.9 to 5.5). The results showed that Bradyrhizobium sp. BGR 3 inoculant tended to increase soybean plant height on acid mineral soil, but LP 3 inoculant was able to increase shoot root ratio and tended to increase N uptake 62.86% on acid mineral soil. The addition of lime was able to increase the growth of soybean plants on acidic mineral soil and increased N uptake 4.08%. The combination of LP 3 inoculant and without liming was able to increase shoot root ratio of soybean 133,33% on acid mineral soils.

Published: October 2022

By June 1, 2022, there were 38 prophylactic COVID-19 vaccines approved in 197 countries around the world. The ongoing approval of new vaccines and the accumulation of more than a year's worth of data on their use give particular importance to the consolidation and analysis of information on the safety of such vaccines.

The aim of study was to analyse the information on adverse events after immunisation (AEFIs) with coronavirus vaccines in the individual case safety reports entered into the VigiBase database by June 1, 2022.

Materials and methods: the author analysed safety reports retrieved from VigiBase through the VigiLyze interface in the expert access mode. The search was carried out using the generic keyword “Covid-19 vaccine” in combination with the trade names of all 38 coronavirus vaccines.

Results: the article presents consolidated information on the number and content of the safety reports on COVID-19 vaccines. The author noted that the reports were characterised by a high level of information completeness and quality, which could be due to the fact that the main reporters were the countries with developed pharmacovigilance systems. The analysis of patient complaints showed that the reported symptoms of AEFIs coincided with the manifestations of side effects of the vaccines included in the package leaflets. The author carried out a review of the cases of serious AEFIs and the cases of adverse events of special interest requiring additional monitoring after immunisation. It revealed a positive correlation of individual vaccines with the cases of somnolence in post-COVID-19 patients.

Conclusions: the data obtained on the global safety of coronavirus vaccines may be of practical interest to doctors, researchers, developers, and healthcare regulators.

East Java has tremendous potential as a center for an integrated Halal industry based on superior products/products/services. East Java also has halal-certified MSMEs, dominated by the food and beverage sector (mamin). So the purpose of this study is to examine the profile of food MSMEs and describe the level of readiness of food MSMEs related to the halal industry in East Java. Methods This research uses a blended method, namely quantitative descriptive and qualitative methods. The exploration method is through the Rapid Rural Appraisal (RRA). Response selection using a purposive sampling technique. The results of the descriptive analysis of the profile of MSMEs who became respondents in this study were that most MSMEs already had NIB and PIRT. Most MSMEs that have NIB also have PIRT (48.72%). Ownership of NIB and PIRT is a commitment of MSMEs to comply with the government's business administration regulations. This shows the manager's administrative order, which is the key in developing the halal industry and culture. In conclusion, SMEs with PIRT also have a halal policy, have attended halal training, and are orderly in selecting and taking an inventory of a well-organized list of materials, products, and equipment, inventory management, procedures, and traceability. However, in terms of product handling, internal audit, and administrative review, many people still use PIRT, even though they already use it. Therefore, the focus of support is on these issues.
