Bridging the Gap: Examining the level, trends and determinants of Adequacy of Quality Antenatal Care in India
Authors: Nihal Saif 
Published: July 2023

Abstract

Background
Antenatal care (ANC) is an important component of the continuum of care for a mother’s health as it is a complete package of not only timely diagnosis of obstetric conditions but it also awares women about the sign of complications due to pregnancy and the importance of family planning and breastfeeding. It has been estimated that by increasing coverage as well as the quality of ANC nearly all maternal deaths are preventable in low- and middle-income countries. However, there have been very few studies with regard to quality antenatal care in India. Therefore, this study attempts to assess the adequacy of quality ANC in India.
Objectives
Firstly, it attempts to understand the trends and patterns in components of quality ANC and secondly it analyses the determinants of quality ANC in India.
Data & Methods:
This study is based on data from National Family Health Survey. The dependent variable is the quality of antenatal care composed of skilled health care, timeliness, sufficiency, and appropriateness in content. Both bivariate and multivariate generalised ordered logit regression analysis has been employed.
Results
The findings indicate that in 2015-16, there were 16% of births without antenatal care, which decreased to just 6% in 2019-21. Despite significant improvement, the components of antenatal care are far from the requirement of Sustainable Development Goals (SDG). The overall quality of antenatal care is just 33% in NFHS-5, rising 10 percentage points from NFHS-4. Southern state has highest utilisation of adequate quality of ANC. The utilisation of adequate quality of ANC increases with women’s education, wealth quintile and decreases with birth order. It is higher in urban areas; those covered by health insurance and have mass media exposure.
Conclusion
Despite some improvements in coverage of antenatal care, the quality of antenatal care is very low in the country and requires urgent attention by policy and program makers.

Published: July 2023

Abstract

Introduction. Developing breast cancer affects the functioning of the patient at all stages of treatment. The sense of control over one’s health contributes to coping with stress, the sense of empowerment, and the doctor-patient relationship.
Objective. The aim of the study was to determine the sociopsychological and demographic factors that protect patients with breast cancer from losing the sense of control and those that foster such loss.
Materials and methods. The research was conducted on 132 female patients of the oncology clinic in Poland at various stages of treatment. Three stages were distinguished: Women during chemotherapy (n = 41), patients of the physical therapy ward after the completion of oncological treatment (n = 40), and the group of “Amazons” (n = 50) who have experienced at least five years of remission after the end of treatment. The research was conducted with the use of demographic data, the Fatalist Loss of Control Scale, the Religious Problem Solving scale, and the scale of perceiving God.
Results and conclusions. There was a negative correlation between the loss of control and the number of planned tasks (life projects) and the faith in the realisation of such projects. The results demonstrated that the sense of losing control increased along with the duration of the illness and decreased with faith in an active, powerful God. The results have been interpreted according to the compensation control theory. They demonstrate that the sense of control over one’s health is closely linked to the dynamics of the treatment process and the quality of life. The presented results may constitute a basis for developing support programmes based on a model of the sense of control over health, which may translate into an ability to better cope with the disease and into patients’ involvement in the treatment process.

Published: July 2023

Abstract

This study maps the shifts in subnational climate change issue priority and risk perceptions in China, based on datasets from two large-scale surveys conducted over 13 years. Our findings reveal significant increases in climate change issue priority and perceived impact (19% and 13%, respectively) at the national scale but wider regional disparities. We highlight the needs for tailored and targeted communication strategies to mitigate the spatial mismatch between climate change perception and risk exposure.
An Implementation Technology for Intelligent Sensor Network Security Communication Based on the Elliptic Curve Encryption Algorithm
Authors: Liu Deliang , Lu Biao , Zhou Wei 
Published: July 2023

Abstract
In this paper, the ECC main algorithms are introduced in detail, the mathematical principles of elliptic curve theory are studied, and the realization of point addition, point doubling and point multiplication in the rapid implementation of elliptic curve cryptographic algorithms on prime field Fp-specific plans are proposed. We discuss the security of elliptic curve cryptosystems and analyze the theoretical basis and algorithmic principle of elliptic curve encryption. This paper also analyzes the mathematical theoretical foundation of elliptic curve cryptography, especially elliptic curve theory in finite fields, and proposes a high-performance elliptic curve cryptography scheme on the basis of the corresponding elliptic curve theoretical background. The feasibility of the system is verified by a software model. Furthermore, the performance of the two protocols is compared in the simulation experiment because the new protocol employs special measures in path design, so it is much better than DD in terms of the unit event transmission energy consumption, average delay time, and event transmission success rate protocol. The key management scheme, which is based on the elliptic curve, is suitable for distributed UWSNs and can authenticate node identity before the shared key is established. Before the node is deployed, the base station preallocates system parameters to the node, and before the two nodes communicate with each other, the identity of the node is authenticated; after the authentication is successful, the two nodes exchange their respective passwords. The round key is iteratively generated through the logistic chaotic map, and the round function is constructed from a discrete double chaotic system. Through analysis, the algorithm meets the security requirements and can resist attacks. The simulation results show that, compared with the DES and AES encryption algorithms, this algorithm consumes fewer resources and is suitable for underwater sensor networks.

Abstract

The deep sea harbours microorganisms with unique life characteristics and life activities due to its special environmental conditions, but the limited sample collection and pure culture techniques available constrain the study of deep-sea microorganisms. In this study, strain Ant34-E75 was isolated from Antarctic deep-sea sediment samples and showed the highest 16S rDNA gene sequence similarity of 97.18%. Polyphasic taxonomy results suggested that strain Ant34-E75 is a new member of the genusAequorivita. Strain Ant34-E75 belongs to the psychrotrophs and can effectively increase the cold tolerance ofChlamydomonas reininatus. Subsequent transcriptome analysis revealed multiple mechanisms involved in the Ant34-E75 response to temperature stress, and weighted gene co-expression network analysis (WGCNA) showed that the peptidoglycan synthesis pathway was the key component. Overall, this study provides insights into the characteristics of deep-sea microorganisms, elucidates the mechanism of temperature adaptation at the molecular level. Furthermore, it enriches our understanding of the species and genetic diversity of deep-sea microorganisms.

Published: July 2023

Abstract

Morphometric analysis plays a key role in understanding the geological and hydrological behavior of watersheds and their prioritization for soil conservation. The conventional methods of determining the morphological characteristics of a basin are expensive and time-consuming. Therefore, in this study, a remote and satellite sensing tools were used to delineate and analyze the linear, areal, and relief aspects of the morphometric indices of the six largest river basins of Dinajpur district which is agro-ecologically an important but drought-prone area in Bangladesh. The river basins are Dinajpur Sadar-Birganj (DS-B), Dinajpur Sadar-Khansama (DS-K), Chirirbandar-Khansama (C-K), Nawabganj-Chirirbandar (N-C), Birampur-Parbatipur (B-P), and Hakimpur-Parbatipur (H-P). The Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model with 30m resolution was used for delineating the river basins. The identified catchments were prioritized based on the morphometric indices and ranked according to their hydrological response to soil erosion. The results of the bifurcation ratio, length of overland flow, drainage density, drainage texture, and constant channel maintenance indicated that the catchments were well-dissected and had less flood and erosion risk. The values of form factor, elongation ratio, circularity ratio, and compactness coefficient dictated an elongated shape of all the basins with a mature geological adjustment. The prioritization of these basins signified that DS-B is the most susceptible catchment and requires a sustainable development decision making framework for its management. This research emphasizes the need for extending this study on the investigated as well as the uninvestigated basins at the micro-level to further prioritize the most vulnerable segment within the basins.
The nature and distribution of non-functional alleles suggest only two independent events at the origins of Astyanax mexicanus cavefish populations

Published: July 2023

Abstract
Background
Several studies suggested that cavefish populations of Astyanax mexicanus settled during the Late Pleistocene. This implies that the cavefish’s most conspicuous phenotypic changes, blindness and depigmentation, and more cryptic characters important for cave life, evolved rapidly.
Results
Using the published genomes of 47 Astyanax cavefish from la Cueva de El Pachón, El Sótano de la Tinaja, La Cueva Chica and El Sótano de Molino, we searched for loss-of-function mutations in previously defined sets of genes, i.e., vision, circadian clock and pigmentation genes — non-functional alleles for four vision genes were identified. Then, we searched genome-wide for non-functional alleles in these four cave populations. Among 512 genes with segregating non-functional alleles, we found an enrichment in visual perception genes. Among cavefish populations, different levels of shared non-functional alleles were found. Using a subset of 12 genes for which loss-of-function mutations were found, we extend the analysis of shared pseudogenes to 11 cave populations. Using a subset of six genes for which loss-of-function mutations were found in the El Sótano del Toro population, where extensive hybridization with surface fish occurs, we found a correlation between the level of eye regression and the amount of non-functional alleles.
Conclusions
We can confirm that very few non-functional alleles are present in a large set of vision genes, in accordance with the recent origin of Astyanax mexicanus cavefish. Nevertheless, the genome-wide analysis indicates an enrichment of loss-of-function alleles in genes with vision-related GO-terms, suggesting that visual perception may be the function chiefly impacted by gene losses related to the shift from a surface to a cave environment. The geographic distribution of the loss-of-function alleles supports the hypothesis that cave populations from Sierra de Guatemala and Sierra de El Abra share a common origin, albeit followed by independent evolution for a long period of time. It also supports that populations from the Micos area have an independent origin. In El Sótano del Toro, the troglomorphic phenotype is maintained despite massive introgression of the surface genome.

Abstract

This study aimed to assess the efficacy of an anticoccidial vaccine and the anticoccidial activity of Aloe vera in broiler chickens infected with Eimeria tenella. A total of 225 healthy one-day-old, unsexed broiler chicks (avian48) from a commercial broiler company were randomly divided into nine experimental groups, with 25 chicks in each group. The groups included: Group 1 (control, vaccinated, non-infected), Group 2 (vaccinated and infected with 5×104 sporulated oocysts), Group 3 (vaccinated, infected with 5×104 sporulated oocysts, and treated with Aloe vera), Group 4 (infected with 5×104 sporulated oocysts and treated with Aloe vera), Group 5 (positive control, infected with 5×104 sporulated oocysts), Group 6 (challenged with 5×104 sporulated oocysts and then treated with amprolium), Group 7 (treated with amprolium), Group 8 (blank control negative group), and Group 9 (treated with Aloe vera gel). Various parameters including clinical signs, growth performance, oocyst shedding, hematological and immunological parameters, and pathological lesion scoring were evaluated. The results showed that Aloe vera improved growth performance, reduced oocyst shedding, and decreased caecal lesion scores in broiler chicks infected with Eimeria tenella. The use of Aloe vera in combination with either amprolium or anticoccidial vaccines provided a potential solution to the issues of drug resistance and drug residues. In conclusion, this study provides valuable insights into the control of coccidiosis in broilers. Supplementing the chicken diet with Aloe vera had beneficial effects on the pathogenicity and infectivity of Eimeria tenella, making it a cost-effective alternative as an herbal extract with no adverse side effects for coccidiosis control. These findings suggest that Aloe vera can be considered as a potential candidate for inclusion in broiler diets to effectively control coccidiosis.
Novel islands of GGC and GCC repeats coincide with human evolution

Published: July 2023

Abstract
Background
Because of high mutation rate, overrepresentation in genic regions, and link with various neurological, neurodegenerative, and movement disorders, GGC and GCC short tandem repeats (STRs) are prone to natural selection. Among a number of lacking data on those STRs, the 3-repeats of these STRs remain widely unexplored.
Results
In a genome-wide search in human, here we mapped GGC and GCC STRs of ≥ 3-repeats, and report islands of up to 45 of those STRs, populating spans of 1 to 2 kb of genomic DNA. RGPD4 and NOC4L harbored the densest (GGC)3 (probability 3.09061E-71) and (GCC)3 (probability 1.72376E-61) islands, respectively, and were human-specific. We also found prime instances of directional incremented density of STRs at a specific locus in human versus other species, including the FOXK2 and SKI GGC islands. The genes containing those islands significantly diverged in expression in human versus other species, and the proteins encoded by those genes interact closely in a physical interaction network, consequence of which may be human-specific characteristics such as higher order brain functions.
Conclusion
We report novel islands of GG C and GCC STRs of evolutionary relevance in human. The density, and in some instances, periodicity of these islands support them as a novel genomic entity, which need to be further explored in evolutionary, mechanistic, and functional platforms.

Abstract
To effectively solve the problem of wastewater pollution. In this paper, a starch (St) based natural polymer cationic flocculant (DMSt-g-DMC) was prepared via a tetherification, esterification and grafting co-polymerization triple modification using corn starch as raw material, 3-chloro-2-hydroxypropyl triethylammonium chloride (CTA), vinyl acetate (VAC) and methylacryloxyethyltrimethyl ammonium chloride (DMC) were used as etherifying agents, esterifying agents and grafting monomers. The results by FT-IR, 13C NMR and XPS showed that acetyl, quaternary ammonium and DMC grafted chain segments were introduced into the starch macromolecular backbone. XRD, SEM analysis and polarized light observation showed that the structure of DMSt-g-DMC was disrupted water solubility was increased. Zeta potential test showed DMSt-g-DMC has increased positive charge quantity and isoelectric point PI. GPC analysis showed that DMSt-g-DMC maintained a high molecular weight and increased the degree of branching to improve flocculation performance. 94.1% removal of acid light yellow G by DMSt-g-DMC, 83.7% and 97.1% removal by reactive brilliant blue X-BR and direct lake blue 5B, respectively. St-g-DMC had a wide flocculation window from 5 g/L to 12 g/L. It also maintained good flocculation performance over a wide pH range. This is advantageous for treating wastewater with high alkalinity and complex composition.
MiR-130a-3p inhibits endothelial inflammation by regulating the expression of MAPK8 in endothelial cells
Authors: Gu Mingming , Liu Kun , Xiong Hui , You Qingsheng 
Published: July 2023

Abstract
MicroRNA-130a-3p (miR-130a-3p) has been reported closely related to atherosclerosis(AS). This study is to survey the effects of miR-130a-3p in endothelial cells (ECs) treated with oxidized low-density lipoprotein (ox-LDL) and explore underlying mechanisms. The proliferation and apoptosis of ox-LDL-treated HUVEC cells were determined by CCK-8, EdU and flow cytometry assays. ELISA and western blot analysis measured the expressions of cytokines and protein levels. Bioinformatics and dual-luciferase reporter assay were performed to predict and confirm that Mitogen-activated protein kinase 8 (MAPK8) was a direct target of miR-130a-3p, and MAPK8 was negatively associated with miR-130a-3p. As expected, miR-130a-3p was down-regulated in ox-LDL-treated HUVEC cells, and up-regulation of miR-130a-3p promoted proliferation and inhibited apoptosis of ox-LDL-treated HUVEC cells. Furthermore, miR-130a-3p mimics suppressed the expressions of TNF-α and IL-6 and decreased the protein levels of VCAM-1, ICAM-1 and E-selectin. MAPK8 was highly expressed in ox-LDL-treated HUVEC cells, and silence of MAPK8 promoted proliferation, inhibited apoptosis, suppressed inflammatory responses, and decreased the levels of VCAM-1, ICAM-1 and E-selectin, over-expression of MAPK8 partially restored the functional effects of miR-130a-3p on proliferation, inflammatory responses, and the expressions of VCAM-1, ICAM-1 and E-selectin. This study indicates that miR-130a-3p may emerge as an effective target for treating AS.

Abstract
The problem with sleep disorders is that they are frequent, often severe, and obstruct the patient's recovery and quality of life. Therefore, it is extremely important to identify new anti-Sleep Disorders agents. The objective of this research was to identify potent anti-sleep disorders agents using screening that combined molecular docking, dynamics. As part of this study, we have screened 20 compounds of Cannabis sativa L plants against orexin. Drug-like filters and ADMET analysis were used to refine the selected molecules. Based on the results of drug like and ADMET, we use the docking tools aids to visualizing and analysing protein-ligand complexes at the atomic level. In the end, two hits were chosen for molecular dynamics simulation. Results showed that two hits had potent inhibitory activity and excellent ADMET characteristics, and they might be used as new leads for the development of potent anti-sleep drugs. MD simulation study is applied for these two hits during 50 ns. As a result of these in-silico experiments, there is a strong basis for further investigation into their anti-Sleep properties.
Estimation of possible isothermal supersaturation of solutions in porous media
Authors: Tikhonov Nikolay 
Published: July 2023

Abstract

The phenomenon of isothermal supersaturation of solutions in a porous medium at ion exchange is studied on the basis of mathematical modeling. The phenomenon consists in the fact that the solution with concentration significantly higher than the maximal solubility of the substance is formed in the pores of sorbent and no precipitation occurs. The question of why sediment does not appear in the pores between the grains is investigated in the article. It is shown that the phenomenon under consideration can be explained by the effect of dynamic equilibrium between the association of condensed phase particles in the inner part of the pores, their diffusion, and decomposition near the surface of the sorbent grains caused by a change in potential. The degree of possible supersaturation of the solution is estimated depending on the process parameters. The proposed hypothesis is confirmed by quantitative studies using the available experimental data.
