Salt-sensitive hypertension: modern pathogenetic mechanisms and prospects
Authors: Antropova O. N. , Obraztsova L. A.
Published: April 2023

The article presents the recent data on the pathogenic links and potential targets for the treatment of salt-sensitive hypertension (HTN). Distinguishing salt-sensitive and salt-resistant phenotypes is one approach to personalized medicine. In the review, special attention is paid to the intestinal microbiota as an etiological factor in salt-sensitive HTN, which, along with the imbalance of neurohumoral systems and the subsequent dysregulatory hemodynamic response to salt load, plays a leading role in the development of salt sensitivity. The advantages and limitations of methods for quantitative assessment of sodium intake are discussed, ways of their optimization are indicated, which is necessary for a more accurate determination of the optimal threshold for salt intake.

Published: April 2023

Background: India has very rich diversity of medicinal plants. Medicinal plants are thought to be a rich source of ingredients that can be used in the development of pharmaceutical or synthetic drugs. Aside from that, these plants play an important role in the development of human drug all over the world. Whether in modern or traditional medicine, medicinal plants are used to maintain health, to treat a specific condition, or both. Nardostachys is one of the most important medicinal plant having several therapeutic properties. It is threatened in its natural habitat due to over exploitation for therapeutic purposes and high demand in the traditional medicine system. Keeping these points in mind, we attempted to investigate alternative uses of in vitro grown plants in place of wild plants without disrupting plant-based therapeutics and market demand. And then compare the root extract of the Nardostachys jatamansi plant’s antioxidant and flavonoid levels under in vitro and natural growth conditions. Methods: Nardostachys jatamansi is a plant that is widely used in traditional medicine systems. Because of its wide spread use in traditional medicine, this plant is considered endemic. In our study, we compare of antioxidant quality and Flavonoid amount of Natural and in vitro propagated Nardostachys jatamansi. Firstly we cultivated in vitro plants from Nardostachys jatamansi nodal explants for comparative analysis. The methanol extract of in vitro grown and wild-type plant root extract was then prepared using the maceration method. The extract was subjected to a comparative DPPH method to determine the presence of antioxidant potential in natural and in vitro grown plants. Furthermore, the HPLC analysis was used to detect and quantify the amount of Quercetin in both natural and in vitro propagated plants. Result: When grown in vitro at a higher concentration, the roots of Nardostachys jatamansi have greater antioxidant potential than when they are grown naturally. They demonstrated antioxidant DPPH radical scavenging activity, with an IC50 value of 29.55 µg/ml for in vitro generated plants and 24.18 µg/ml for naturally grown plants. The concentration of Quercetin (mg/ml) for natural plant species is 1.95 and for in vitro propagate plant is 1.83. The HPLC analysis presents distinct peaks, with the main peaks having retention time for standard Quercetin (10.38) in the natural plant (10.34) and in vitro grown plants (10.32). In the end, natural-type species that had been produced in vitro were used to obtain the potential of micro propagated plants. The DPPH test and flavonoid were tested on the root extract of natural and in vitro plants. Both plants displayed promising antioxidant activity and an HPLC study identified the Quercetin component.

Authors: Winly  , Supit Fabiola , Andayani Ari , Suryathi Ni Made Ari
Published: April 2023

Introduction: The primary treatment in proliferative diabetic retinopathy (PDR) is vitrectomy; however, direct intervention to the dense proliferative fibrovascular membrane may lead to massive hemorrhage obscuring the surgery process. Purpose: to review the use of anti-vascular endothelial growth factor (VEGF) as an adjuvant therapy before pars plana vitrectomy in PDR cases. Review: Anti-VEGF has been proposed as an adjuvant preceding the vitrectomy to lower intraoperative and post-operative complications. On the other hand, it could increase fibrosis which triggers tractional retinal detachment (TRD) in PDR cases. Conclusion: Intervals of five to ten days are considered the most ideal between anti-VEGF injection and pars plana vitrectomy (PPV) surgery in which the adjuvant therapy has made neovascularization regression and before the occurrence of fibrovascular contractions.
Reconstruction of a Traumatic Large Upper Eyelid Avulsion with Tarsoconjunctival Graft and Rotational Flap: A Surgeon’s Preference
Authors: Fariz Muhammad , Sutjipto
Published: April 2023

Introduction: Large, full-thickness upper eyelid defects management presents a thorough and challenging approach due to the multilaminar character of the eyelid and its dynamic function. The Cutler-Beard flap method has been the mainstay management, but posterior lamellar graft usage with recent modifications may reduce complications. Case Presentation: A 43-year-old man presented to the emergency ward after a traffic accident left him with a full-thickness laceration on his left upper eyelid and an approximately 60% avulsion on the one-third medial of the eyelid. Traumatic ptosis was also found. After considering the large size of the affected area and the probability of faster wound healing, a free graft from the tarsus and conjunctival eyelid of his fellow eye was harvested to replace the posterior lamellar of the affected eye and closed the defect with a rotational skin flap from the remaining of the left upper eyelid. Conclusions: This technique could be one of the alternatives to the more common cutler-beard flap with mild complications. However, temporary visual obstruction cannot be avoided due to the traumatic ptosis complication of this patient.

Published: April 2023

Introduction: Intraocular foreign bodies (IOFBs) are defined as intraocularly retained, unintentional projectiles that require urgent diagnosis and treatment to prevent blindness or globe loss. Case Presentation: We report a case of IOFB due to occupational accidents. In this case, there were delays in extraction considering the health facilities and conditions related to COVID-19 infection. Initially, the patient underwent closure of the entrance wound, which was performed within the first 24 hours post-trauma. However, although there was no endophthalmitis, visual acuity at the end of the observation still showed an unexpected outcome. The patient was followed up for three months after IOFBs extraction. The timing of IOFBs removal depends on several factors, including the patient’s overall health status, the nature of the injury, and the composition of the IOFBs. The postoperative examinations focus on complications such as endophthalmitis, postoperative retinal detachment, proliferative vitreoretinopathy (PVR), and sympathetic ophthalmia. The numerical values can then be used to predict the expected visual acuity using the ocular trauma score system. Conclusions: Many factors could affect the outcome quality of visual acuity. Primary wound closure, foreign body extraction, and anatomic reconstruction of the holistic ocular should be performed as soon as possible. Delay in definitive treatment was thought to affect worsening prognosis due to tissue proliferation and the tendency for severe complications, including endophthalmitis.

Published: April 2023

Microalgae can be part of the solution to the global food crisis, as they have high nutritional values. Recently, 3D printing of microalgae-enriched snacks has been reported with the capability to customize nutritional profiles, shapes, and textures of the snacks. Because the process parameters of extrusion-based 3D printing affect the printability of cookie dough, it is important to know the levels of process parameters leading to continuous extrusion. This study investigated feasible regions of printing process parameters for continuous extrusion of microalgae (Arthrospira Platensis) enriched cookie dough. The process parameters studied were nozzle diameter, printing speed, and air pressure. The feasible regions were determined by visual inspections of printed strands. The results show that, for smaller nozzle diameters and higher printing speeds, higher air pressures are required to ensure continuous extrusion. The identified feasible regions from this study would be helpful when deciding the appropriate nozzle diameter, printing speed, and air pressure to print microalgae-enriched cookie dough and other materials with similar rheological properties in extrusion-based 3D printing.

The Conservation Laws in Quantum Mechanics
Authors: Oldani Richard Joseph
Published: April 2023

It is often claimed that Einstein is wrong about quantum mechanics. However, when comparisons are made with respect to theoretical foundations rather than experimental results Einstein’s theories are found to be superior. Although quantum mechanics correctly predicts what it is possible to observe (the emissions) it ignores the other half of natural phenomena, what cannot be observed (the absorptions), thereby violating the conservation laws. By describing only one-half of radiation processes conceptual difficulties such as wave function collapse, infinite paths, and inscrutable mathematics seem to be insoluble mysteries. The deficiencies are corrected by introducing Hamilton’s principle S = ∫ Ldt and applying the methods of quantum field theory to derive relativistic equations of motion. The calculus of variations is used to show that the wave function represents an incomplete equation of motion because it equals twice the allowable action minimum.

Machine learning (ML) techniques have been applied to various aspects of biofilm research, such as predicting biofilm formation, identifying key genes, and designing new therapeutic strategies. In this study, we conducted a bibliometric analysis of machine learning in biofilm research to provide a comprehensive overview of the current state of the field. We searched the Web of Science database for articles published included "machine learning biofilm". A total of 126 articles were identified and analysed. Our results showed that the number of publications on machine learning in biofilm has been increasing rapidly over the past decade, indicating a growing interest in the application of ML techniques to biofilm research. The analysis also revealed that the most common research topics in this area were related to biofilm formation, prediction, and control. Furthermore, the most frequently used ML techniques in biofilm research were artificial neural networks and support vector machines. Overall, our study provides valuable insights into the current trends and future directions of machine learning in biofilm research. It also highlights the importance of interdisciplinary collaboration between biofilm researchers and ML experts to drive innovation in this field.
Exploring the Interplay of New Energy Vehicle Enterprises, Consumers, and Government in the Context of the 'Dual Carbon' Target: An Evolutionary Game and Simulation Analysis
Authors: Song Rui , Xue Xingjian , Qin Wanyi , Shi Wen
Published: April 2023

To promote low-carbon and green travel, this study proposes a tripartite evolutionary game model among new energy vehicle manufacturers, consumers, and government agencies. The game strategy combinations of each party and the stability conditions of the equilibrium point in the evolutionary game system are analyzed, and the validity of the conclusions is verified through simulation results. The study shows a strong correlation between the three parties in the evolutionary game system. From the perspective of car manufacturers, the probability of producing new energy vehicles is positively proportional to the subsidy received from new energy policy, the additional revenue gained from the management of the carbon trading scheme, and the fine received for producing conventional fuel vehicles. However, from the consumer perspective, the likelihood that consumers purchase new energy vehicles is positively related to the utility value to consumers and the coverage of public charging points in the city, and inversely related to the sales price of new energy vehicles. From the government perspective, a combination of direct subsidy policies and indirect support strategies should be considered to stimulate the rapid development of the new energy vehicle industry.

The Asian weaver ant Oecophylla smaragdina is a natural enemy (predator) used as a biological control agent in Australia and several Southeast Asian nations against the most destructive and economically important oriental fruit fly Bactrocera dorsalis. For biological control of the invasive bagworm species Metisa plana in oil palm plantations, the composition of the colony's social structure was investigated to ensure its efficacy. On two colonies, all castes were examined stereo microscopically after nest collection and dissection. The head's width, head, thorax, abdomen, and body lengths of workers were evaluated during the morphology analysis. All colonies with more than a thousand eggs comprise of a founding egg-laying queen, reproductive winged green and newly emerged yellow queens, as well as adult drone males and workers. Future queens, males, and workers' pupae and larvae comprised immature individuals. It is the first study to characterise one caste of minor workers, two previously unidentified castes of intermediate workers, and two castes of major workers. The lengths of the body and abdomen are proposed as differentiating factors for workers. The discovery of a polymorphic size frequency distribution model contrasts with the consistently reported existence of archetypical bimodal systems in ants. Intermediate workers foraging outside the nest revealed reconnaissance and aggressive behaviours that aided major workers in their daily tasks. Due to their short lifespan and segregated nests, it is difficult to successfully sample adult males in wide plantations. An entire year's worth of reproductive individuals are produced by stable, three-year-old colonies, with a decrease in population size correlated with a significant decline in rainfall interception.

In current study we have obtained Co2FeSi-glass coated microwires with different geometrical aspect ratio, ρ = d/Dtot (diameter of metallic nucleus, d and total diameter, Dtot). The structure and magnetic properties are investigated at a wide range of temperature. XRD analysis illustrates a notable changing in the microstructure by increasing the aspect ratio of Co2FeSi glass coated microwires. Amorphous structure is detected for the sample with the lowest aspect ratio (ρ = 0.23), whereas a growth of crystalline structure is observed in the other samples (aspect ratio ρ = 0.30 and 0.43). This change at the microstructure properties correlates with dramatic changing in magnetic properties. For the sample with the lowest ρ -ratio, non-perfect square loops are obtained with low normalized remanent magnetization. A notable enhancement in the squareness and coercivity are obtained by increasing ρ -ratio. Changing the internal stresses strongly affects the microstructure, resulting in a complex magnetic reversal process. The thermomagnetic curves show large irreversibility for the Co2FeSi with low ρ -ratio. Meanwhile, if we increase the ρ -ratio, the sample shows perfect ferromagnetic behavior without irreversibility. The current result illustrates the ability to control the microstructure and magnetic properties of Co2FeSi-glass-coated microwires by changing only their geometric properties without performing any addition heat treatment. The modification of geometric parameters of Co2FeSi glass-coated microwires allows to obtain microwires which exhibit an unusual magnetization behavior that offers opportunities to understand the phenomena of various types of magnetic domain structures, which is essentially helpful for designing sensing devices based on thermal magnetization switching.
Path Planning Method for Underwater Gravity-Aided Inertial Navigation Based on PCRB
Authors: Wang Bo , Cai Tijing
Published: April 2023

Gravity-aided inertial navigation system (GAINS) is an important development in autonomous underwater vehicle (AUV) navigation. An effective path planning algorithm plays an important role in the performance of navigation in long-term underwater missions. By combining the gravity information obtained at each position with the error information from the INS, the posterior Cram\'er-Rao bound (PCRB) of GAINS is derived in this paper. The PCRB is the estimated lower bound of position variance for navigation along the planned trajectory. And the sum of PCRB is used as the minimum cost from the initial state to the current state in the state space, and the position error prediction variance of inertial navigation system (INS) is used as the minimum estimated cost of the path from the current state to the goal state in the A* algorithm. Thus, a path planning method with optimal navigation accuracy is proposed. According to simulation results, traveling along the path planed by the proposed method can rapidly improve the positioning accuracy while consuming just slightly more distance. Even when measuring noise changes, the planned path can still maintain optimal positioning accuracy, and high positioning accuracy is possible for any trajectory located within a certain range of the planned path.
LPGAN: A LBP-based Proportional Input Generative Adversarial Network for Image Fusion

Published: April 2023

Image fusion is the process of combining multiple input images from single or multiple imaging modalities into a fused image, which is expected to be more informative for human or machine perception as compared to any of the input images. In this paper, we propose a novel method based on deep learning for fusing infrared images and visible images, named the LBP-based proportional input generative adversarial network (LPGAN). In the image fusion task, the preservation of structural similarity and image gradient information is contradictory, and it is difficult for both to achieve good performance at the same time. To solve this problem, we innovatively introduce Local Binary Patterns (LBP) into Generative Adversarial Networks (GANs), which effectively utilize the texture features of the source images, so that the network has stronger feature extraction ability and anti-interference ability. In the feature extraction stage, we introduce a pseudo-siamese network for the generator to extract the detailed features and the contrast features. At the same time, considering the characteristic distribution of different modal images, we propose a 1:4 scale input mode. Extensive experiments on the publicly available TNO dataset and CVC14 dataset show that the proposed method achieves the state-of-the-art performance. We also test the universality of LPGAN through the fusion of RGB and infrared images on the RoadScene dataset. In addition, LPGAN is applied to multi-spectral remote sensing image fusion. Both qualitative and quantitative experiments demonstrate that our LPGAN can not only achieve good structural similarity, but also retain rich detailed information.

Published: April 2023

Historical city textures are living history embodying public open spaces of former civilizations, their landscapes and traditional life cultures, carrying them to the present and giving them life. The squares, which form the public open spaces, have been important meeting centers in the social lives of people. City furniture are the important elements in these public open spaces, reflecting the identity of the city and improving quality of life. City furniture improve the reflection of cultural value in historical city textures and their usability. The walled city center, where the historical city texture of Nicosia lies, has a very rich historical texture with the cultural heritage of various civilizations in the history of Cyprus. Public open spaces within the texture, which have acquired the quality of squares with their functions throughout the social history of Nicosia, are still important social spaces for the people of the city. This study analyzed Asmaaltı and Selimiye Squares, two important spaces of the walled city, through examining the city furniture in terms of their material, shape, and functionality, and their conformity with the historical texture. Their deficiencies and nonconformities with the historical texture were identified accordingly. In consideration with such examples, city furniture in historical city textures were assessed for their conformity with the texture characteristics, architectural styles, social, cultural, and economical characteristics, and relevant recommendations are presented respectively.

The utilization of Fiber Bragg Grating (FBG) sensors in innovative optical sensor networks has displayed remarkable potential in providing precise and dependable thermal measurements in hostile environments on Earth. Multi-Layer Insulation (MLI) blankets serve as critical components of spacecraft and are employed to regulate the temperature of sensitive components by reflecting or absorbing thermal radiation. To enable accurate and continuous monitoring of temperature along the length of the insulative barrier without compromising its flexibility and lightweight, FBG sensors can be embedded within the thermal blanket, thereby enabling distributed temperature sensing. This capability can aid in optimizing the thermal regulation of the spacecraft and ensuring the reliable and safe operation of vital components. Furthermore, FBG sensors offer several advantages over traditional temperature sensors, including high sensitivity, immunity to electromagnetic interference, and the ability to operate in harsh environments. These properties make FBG sensors an excellent option for thermal blankets in space applications, where precise temperature regulation is crucial for mission success. Nevertheless, the calibration of temperature sensors in vacuum conditions poses a significant challenge due to the lack of an appropriate calibration reference. Therefore, this paper aims to investigate innovative solutions for calibrating temperature sensors in vacuum conditions. The proposed solutions have the potential to enhance the accuracy and reliability of temperature measurements in space applications, which can enable engineers to develop more resilient and dependable spacecraft systems.
