The impact of national savings on economic development: a focused study on the ten poorest countries in Sub-Saharan Africa
Authors: Ibe Ndukwe
Published: July 2024

The purpose of this study is to examine the impact of national savings on economic development, as measured by the Human Development Index (HDI), Inequality-adjusted HDI (iHDI), and Multidimensional Poverty Index (MPI), in ten of the poorest countries in Sub-Saharan Africa. The study employs a sequential Generalized Method of Moments (GMM) analysis to address potential endogeneity issues and account for the dynamic nature of the relationships, covering the period from 2009 to 2019. The findings reveal a complex relationship between national savings and the selected development indicators. While national savings exhibit positive impacts on HDI and iHDI, the results are not consistently statistically significant across all the sequential models. However, the analysis suggests that national savings have a positive influence on reducing multidimensional poverty, as measured by MPI, particularly when effectively channeled into productive investments. The study also highlights the significant positive impact of government expenditure and foreign direct investment (FDI) on human development, underscoring the importance of strategic public investments and foreign capital. The results suggest that while national savings are crucial, their effective utilization is essential for enhancing human development indices. Strategic investments in public goods and foreign capital are also important. The mixed effects of inflation and official development assistance (ODA) emphasize the need for stable economic policies and effective utilization of foreign aid. The modest positive impact of institutional quality suggests that improvements in governance and institutional frameworks can contribute to human development. The findings underscore the need for policies promoting financial inclusion, efficient public expenditure, foreign direct investment, and stable macroeconomic conditions to leverage national savings for economic development. The study’s findings provide valuable insights for policymakers in Sub-Saharan Africa, highlighting the need for comprehensive strategies that leverage national savings, public expenditure, and foreign investment to drive sustainable economic development and poverty reduction.
Deubiquitinating enzyme mutagenesis screens identify a USP43-dependent HIF-1 transcriptional response

Published: July 2024

The ubiquitination and proteasome-mediated degradation of Hypoxia Inducible Factors (HIFs) is central to metazoan oxygen-sensing, but the involvement of deubiquitinating enzymes (DUBs) in HIF signalling is less clear. Here, using a bespoke DUBs sgRNA library we conduct CRISPR/Cas9 mutagenesis screens to determine how DUBs are involved in HIF signalling. Alongside defining DUBs involved in HIF activation or suppression, we identify USP43 as a DUB required for efficient activation of a HIF response. USP43 is hypoxia regulated and selectively associates with the HIF-1α isoform, and while USP43 does not alter HIF-1α stability, it facilitates HIF-1 nuclear accumulation and binding to its target genes. Mechanistically, USP43 associates with 14-3-3 proteins in a hypoxia and phosphorylation dependent manner to increase the nuclear pool of HIF-1. Together, our results highlight the multifunctionality of DUBs, illustrating that they can provide important signalling functions alongside their catalytic roles.

Published: July 2024

Cytokinetic abscission marks the final stage of cell division, during which the daughter cells physically separate through the generation of new barriers, such as the plasma membrane or cell wall. While the contractile ring plays a central role during cytokinesis in bacteria, fungi and animal cells, the process diverges in Apicomplexa. In Toxoplasma gondii, two daughter cells are formed within the mother cell by endodyogeny. The mechanism by which the progeny cells acquire their plasma membrane during the disassembly of the mother cell, allowing daughter cells to emerge, remains unknown. Here we identify and characterize five T. gondii proteins, including three protein phosphatase 2A subunits, which exhibit a distinct and dynamic localization pattern during parasite division. Individual downregulation of these proteins prevents the accumulation of plasma membrane at the division plane, preventing the completion of cellular abscission. Remarkably, the absence of cytokinetic abscission does not hinder the completion of subsequent division cycles. The resulting progeny are able to egress from the infected cells but fail to glide and invade, except in cases of conjoined twin parasites.

We have recently identified the uncharacterized ZNF555 protein as a component of a productive complex involved in the morbid function of the 4qA locus in facioscapulohumeral dystrophy. Subsequently named DiPRO1 (Death, Differentiation, and PROliferation related PROtein 1), our study provides substantial evidence of its role in the differentiation and proliferation of human myoblasts. DiPRO1 operates through the regulatory binding regions of SIX1, a master regulator of myogenesis. Its relevance extends to mesenchymal tumors, such as rhabdomyosarcoma (RMS) and Ewing sarcoma, where DiPRO1 acts as a repressor via the epigenetic regulators TIF1B and UHRF1, maintaining methylation of cis-regulatory elements and gene promoters. Loss of DiPRO1 mimics the host defense response to virus, awakening retrotransposable repeats and the ZNF/KZFP gene family. This enables the eradication of cancer cells, reprogramming the cellular decision balance towards inflammation and/or apoptosis by controlling TNF-α via NF-kappaB signaling. Finally, our results highlight the vulnerability of mesenchymal cancer tumors to si/shDiPRO1-based nanomedicines, positioning DiPRO1 as a potential therapeutic target.

2D human skeleton action recognition with spatial constraints
Authors: Wang Lei , Zhang Jianwei , Yang Wenbing , Gu Song , Yang Shanmin
Published: July 2024

Human actions are predominantly presented in 2D format in video surveillance scenarios, which hinders the accurate determination of action details not apparent in 2D data. Depth estimation can aid human action recognition tasks, enhancing accuracy with neural networks. However, reliance on images for depth estimation requires extensive computational resources and cannot utilise the connectivity between human body structures. Besides, the depth information may not accurately reflect actual depth ranges, necessitating improved reliability. Therefore, a 2D human skeleton action recognition method with spatial constraints (2D‐SCHAR) is introduced. 2D‐SCHAR employs graph convolution networks to process graph‐structured human action skeleton data comprising three parts: depth estimation, spatial transformation, and action recognition. The initial two components, which infer 3D information from 2D human skeleton actions and generate spatial transformation parameters to correct abnormal deviations in action data, support the latter in the model to enhance the accuracy of action recognition. The model is designed in an end‐to‐end, multitasking manner, allowing parameter sharing among these three components to boost performance. The experimental results validate the model's effectiveness and superiority in human skeleton action recognition.

Published: July 2024

Disorders of calcium and phosphorus metabolism in rabbits are caused by a violation of the ratio of calcium and phosphorus in their ration, and it was found that the supply rate of rabbits with nutritious substances in the diet is 85.46% calcium, 63.25% phosphorus, 64.0% carotene, 86.15% raw kletchatka, 91.17% dry matter, 91.2% digestible protein. Calcium-phosphorus metabolism disorders in rabbits are accompanied by sympto ms such as altered appetite (coprophagia), pale mucous membranes, hoarseness of the skin coating, loss of glare, the appearance of bulges in the ribs, as well as hypogemoglobinemia, hypocalcemia, hypophosphoremia. As a result of this pathology, abortions can be observed in mother rabbits, or their children born from them will be hypotrophic. Methods have been developed to prevent calcium and phosphorus exchange disorders in rabbits by giving granular lobster baits enriched with Nova Marks (vitamin-mineral premix) premix, mixing the Innoprovet probiotic in water. Granule feed (enriched with 1 kg of Nova Marx premix per 1tonna feed) + innoprovet 1 ml with 1 liter of water (for 7 days) in the period from the 10th day of calving to the 10th day after childbirth is more effective, ensuring an increase in hemoglobin in the blood by an average of 12.7 g/l, total protein in the blood serum-14.06 g/l, total calcium - 1.04 mmol/L and inorganic phosphorus. Vitamin-mineral premix, given in combination with probiotics, improves food digestion in the body of rabbits. This method of prophylaxis prevents calcium- phosphorus exchange disorders in rabbits, in which the increase in body weight is on average 0.51 kg higher than the control.

Authors: Rastriga Nikolay V. , Gasanova Dariya A. , Smirnov Sergey A. , Levashov Pavel A.
Published: July 2024

It was found that glycine, glutamate, lysine, histidine, and arginine increase the rate of Escherichia coli cell lysis by chicken egg lysozyme. The highest cell lysis rates (lysis acceleration by 7.0-8.5 times) are provided by combinations of the following amino acids: 1) arginine, histidine, and lysine, 2) glutamate, histidine, and arginine, 3) glycine, lysine, and arginine (all charged amino acids are applied in concentrations of 5 mM, the concentration of glycine is 1.5 mM). These amino acids added into food products with lysozyme as a preservative can significantly increase antibacterial properties of the latter. This could help increase the shelf life of human food and also serve as a preventive measure against the spread of bacterial infections among farm animals.

Published: July 2024

The paper studied 35 Holstein cows on a dairy farm in Volgograd region in 2023. The cows received a balanced diet with corn silage, hay, concentrated forages, supplements and mineral components to ensure health and productivity as they produced 40 kg of milk with a fat content of 3.7% daily. Cows diagnosed with postpartum metritis were injected subcutaneously with ceftiofur hydrochloride at a dose of 1 mg/kg body weight. Vaginal discharge was evaluated on day 10 after diagnosis. If discharge persisted, it indicated lack of recovery. Recovery was confirmed if there was no change in the structure and vaginal discharge by day 21. The study showed that the use of ceftiofur for the treatment of cows with metritis was not negatively associated with reproductive performance and productivity of the study cows, but was strongly associated with uterine inflammation. There was no direct reduction in the association between reproductive performance and key production parameters in the study, while there was a high correlation with cow disease such as metritis. The standard deviation for cows diagnosed with metritis was 59.40, metritis + retained placenta - 7.42, metritis + uterine atony - 14.85, metritis + retained placenta + uterine atony - 3.71.

Authors: Rondhi M. , Nanda Arrizka I.P.
Published: July 2024

Subsidised fertiliser is a government’s effort to increase the purchasing power of farmers in meeting their agricultural input needs by setting the highest retail price (HET). It is intended to be the highest price that can be charged for subsidised fertilisers. Based on the regulations that have been in place since 2017, the distribution of subsidised fertilisers is carried out through the Farmer Card. However, in its implementation thus far, the Farmer Card has not been optimally used for both fertiliser purchase transactions and agricultural credit collection. The purpose of this study is to determine farmers’ perceptions and factors influencing farmers’ adoption of the card in Jember District. The data analysis method used was descriptive analysis using weighted average index analysis and binary logistic regression. The results showed that access to information and the certainty of benefits in obtaining subsidised fertilisers were included in the strong category influencing farmers’ perceptions of the card. This means that farmers have high enthusiasm for using the Farmer Card but are not supported by available information and facilities. Therefore, the role of extension workers and supporting facilities is needed to implement this program immediately.
Strategy to accelerate the implementation of sustainable food agricultural land protection regulations
Authors: Ar-Rozi Ahmad M. , Suryani Erma , Adawiyah Cut R. , Dabukke Frans B.M. , Sarwani Muhrizal
Published: July 2024

Sustainable food agricultural land (especially paddy fields) is an important issue because it affects national food self-sufficiency, security, and sovereignty. The government has issued Law No. 41/2009 on sustainable food agricultural land (LP2B) to protect agricultural land and control the rate of land conversion. The main problem is its ineffective implementation. This paper aims to analyse the problem of ineffective implementation of Law No. 41/2009. The study was conducted in January-July 2023 in West Java and Lampung Provinces using primary and secondary data. The methods of analysis used were qualitative and descriptive. The results showed that local governments are not entirely concerned about protecting agricultural land (especially paddy fields). Regional leaders’ weak commitment to protecting food agricultural land has made the program a much lesser priority. Coordination across sectors has not been effective. Based on these empirical facts, the strategy to accelerate the implementation of Law No. 41/2009 is to encourage regional leaders’ commitment to prioritise LP2B protection programs. Furthermore, the Ministry of Agriculture can intervene by providing stimulus funds of assistance to accelerate the issuance of Regional Regulations on LP2B, especially in areas that have not yet issued LP2B regional regulations.
Rice fortification and biofortification as a potential strategy to alleviate stunting and bolster food security in Indonesia
Authors: Luna Prima , Suryana Esty A.
Published: July 2024

Indonesia has regained its status as an upper-middle income country in the latest category released by the World Bank in July 2023, owing to a robust post-pandemic recovery. The present economic recovery is anticipated to result in a GDP growth rate of 5.1% by 2022. Furthermore, Indonesia has significantly reduced its stunting prevalence, declining from 37% in 2013 to less than 21.6% in 2022. Nevertheless, further tasks need to be accomplished to guarantee the robust and effective development of human capital. Biofortification and rice fortification with micromineral zinc to increase nutritional value are potential strategies to combat stunting and enhance food security. The methodology employed a literature review and both qualitative and quantitative data analyses. This article discusses the implementation of this policy in Indonesia. Key issues arising from the implementation of this policy are: 1) rice is widely consumed and suitable for adoption as a food vehicle for fortification; 2) the rice seedling system must be robust to produce targeted varieties; 3) ensuring premix vitamins and micronutrients are halal certified; and 4) ensuring rice fortification and biofortification meet the standards and guidelines for food safety and quality before donation to the targeted community.

The content of soil humus when using organic and mineral fertilizers
Authors: Kloster Natalia , Azarov Vladimir , Lotkova Viktoria
Published: July 2024

This article suggests that the content of humus is the ability of the soil to adapt to human economic activity. The scientific team conducted a three-year field experience, taking into account the humus state of the soil in two terms. Conclusions are made based on the data obtained. The use of organic fertilizers contributes to a positive balance of humus. The amount of the increase varies from 0.06% to 0.14%. The increase in humus content is directly proportional to saturation with mineral nutrition (from 0 to 1 full dose). Mineral fertilizers reduce the loss of soil humus. The dependence is reversed: with a full dose of fertilizers, the decrease in humus content over 3 years is -0.11%, with a half dose -0.12%, and with zero -0.14%. To effectively preserve and increase the humus content in the soil, 14 tons/ha of compost based on bird droppings and a full dose of mineral fertilizers calculated based on the needs of different crops should be applied.

This paper discusses methods of obtaining fuel briquettes from hydrocarbon-containing waste of oil refineries as a binder, as well as conducts a comparative analysis of the operational characteristics of the obtained products and previously known fuel briquettes. To improve the operational properties of oil sludge briquettes, research is conducted and an optimal composition of the fuel briquette based on licorice root waste in combination with a binder mixture based on oil and fat residues is proposed. The paper provides a technology for obtaining a binder mixture based on oil and fat residues. Six types of alternative road bitumen samples based on the developed composition have been obtained, and research has been conducted on the following indicators: water absorption of the fuel briquette, total moisture in the fuel briquette, degree of ash content, and the amount of total sulfur in the fuel briquette. The article also presents a recommended technological scheme for the production of fuel briquettes using licorice root waste as a binder mixture.

Published: July 2024

Areas of active farming undergo significant soil erosion atcatchments and pollution of surface waters and bottom sediments. Whenthese issues in mining regions are coupled with the effects of drainage waterand dust emissions from open-pit mining, it becomes critical to evaluate andmonitor contamination of water bodies and bottom sediments. The aim ofthis work was to compare the ecological and geochemical characteristics ofsediments in water bodies within the Kursk Magnetic Anomaly (KMA),which has open-pit mining, with rivers and ponds affected by agro-industrialeffluents, excluding the impact of drainage water. The concentrations ofseveral heavy metals (Pb, Zn, Cu) and organic matter content in bottomsediments were greater in the Belgorod Oblast than the iron ore district.When using indicators of regional background for KMA water bodies, theman-made impact on sediment pollution was determined, which is reflectedin excess concentrations of Mn, Zn, Cu (from 1.5 to 2.8 times). Research ofsurface and groundwater transformations, their interactions, and thepeculiarities of pollutant migration provide the foundation for developing amonitoring system for water bodies affected by mining operations to supportmanagement decision-making.
