Published: January 2024

Purpose of the study. To assess the quality of life of children with hereditary disorders of connective tissue development and their parents during dynamic monitoring in a polyclinic. Material and methods. In the period from 2020 to 2023, the patients were under dispensary observation. The main group of patients (n=30) and the comparison group (n=30) are presented. At the beginning of treatment, the average age was 4.7±0.5 years. For patients of the two groups, therapeutic measures were proposed, which included back massage (ten sessions once in 4 months), electrical stimulation of the back muscles (ten sessions once in 6 months), and a physical therapy complex. Additionally, patients from the main group were prescribed sessions at the school "Posture Correction", swimming, bracing, additional physiotherapy complexes (electrical stimulation of the back – 3 courses of 10 sessions per year), back massage (10 sessions every month), diet and vitamin therapy for 3 years. The quality of life was assessed using the PedsQL questionnaire. Results. It was statistically significantly proved that during the period of dispensary observation, the patients of the main group and their parents improved physical parameters in 65.0% of cases (in the comparison group in 20.3% of cases), p=0.016; emotional parameters improved in 59.8% of cases (in the comparison group in 21.0% of cases), p=0.014. At the same time, a satisfactory muscular corset was visualized, which was confirmed by additional examination methods (electroneuromyography, stabilometry); complications from the osteoarticular system were reduced. In patients from the comparison group and their parents, the quality of life did not change statistically significantly. The patients noted hypotonia of the back muscles in 53% of cases and pain on palpation along the spine in the thoracic region in 37.3% of cases (p<0.001). Conclusions. Over time, in the main group, the number of complications from the osteoarticular system was minimized and the quality of life in patients of the main group and their parents significantly improved.

Background. The problem of acute pain control after orthopedic and traumatological operations in children has not been completely solved. This article presents data from our own research on the effectiveness of postoperative anesthesia in orthopedic and traumatological surgical interventions on the lower extremities in children. Objective. To determine the effectiveness of postoperative anesthesia in orthopedic and traumatological operations on the lower extremities in children performed using multicomponent balanced general and combined anesthesia. Material and methods. A single-center prospective simple blind randomized study was conducted. The study included 52 patients aged 6 to 17 years who underwent planned orthopedic and traumatological surgical interventions on the lower extremities. Depending on the method of anesthesia the patients were divided into two groups: in group 1 (n=22), children underwent multicomponent balanced general anesthesia, in group 2 (n=30) – combined anesthesia (multicomponent balanced general anesthesia in combination with regional blockades of the sciatic and femoral nerve). After the surgical interventions the duration of postoperative anesthesia, the need for analgesics were estimated, and a quantitative assessment of the severity of acute pain on the Wong-Baker scale 2,6,24 hours after the end of the operation was performed. Results. In all cases, surgical interventions were successful. As a result of the study, it was found that the duration of postoperative anesthesia in the group of children where combined anesthesia was used was 305 [215; 385] minutes. In the group of patients who underwent multicomponent general anesthesia, the duration of anesthesia was 8.7 times less and amounted to 35 [10; 65] minutes. In patients of group 1, the pain score on the Wong-Baker scale 2 hours after surgery was 3 [2; 4] points, after 6 hours 3.5 [2; 5] points, after 24 hours 2 [1; 3] points; in patients of the 2nd group 0 [0; 1], 3,5 [0; 5], 2 [1; 3] points, respectively. Narcotic analgesics were used in 14 (64%) of 22 children of group 1 and 15 (50%) of 30 children of group 2. Paracetamol was used in 19 (86%) of 22 patients of group 1 and 28 (93%) of 30 patients of group 2; ketorolac in 2 children (9%) from the 1st group and 3 children (10%) from the 2nd group. Conclusion. Combined anesthesia provides longer postoperative anesthesia and reduces the need for narcotic analgesics in the postoperative period during orthopedic and traumatological operations on the lower extremities in children.

Singlet Oxygen (SO) generation is the core chemical process of many medical and industrial applications. Designing efficient SO-Generating (SOG) agents is a major research focus for its utility in photodynamic therapy, wastewater treatment, material science, and organic synthesis. Photosensitization of ambient oxygen using organic dyes is an efficient approach to generating SO, though their efficiency is often severely hampered due to aggregation-induced deactivation. In this manuscript, we present the utility of bile salt micelle as supramolecular host for promoting SOG in aqueous media for a BODIPY dye, which was otherwise highly inactive. The SOG efficiency in test media was probed by monitoring the oxidation of 1,5-Dihydroxy Naphthalene (DHN) to corresponding quinone (juglone) through spectroscopic and chromatographic methods. In this study, we investigated the use of bile salt micelles as a supramolecular platform for enhancing the SOG efficiency of a BODIPY dye in aqueous media through complexation. Our results show that sodium cholate micelles can solubilize the hydrophobic dye and enhance its ability to generate singlet oxygen, while traditionally used macrocyclic hosts such as Β- and γ-cyclodextrin complexation was found to be far less efficient. Computational modeling revealed that the bile salt micelles form an aggregated complex structure with the dye, leading to improved supramolecular interactions and photophysical properties. This work demonstrates the potential of bile salt micelles as a natural and safe platform for enhancing the activity of nonpolar dyes for PDT applications.

Published: January 2024

Landfilling has long been the most common method of disposal for municipal solid waste (MSW). However, many countries seek to implement different methods of MSW treatment due to the high global warming potential associated with landfilling. Other methods such as recycling and incineration are either limited to only a fraction of generated MSW or still produce large greenhouse gas emissions, thereby providing an unsustainable disposal method. Here, we report the production of graphene from treated MSW, which includes treated wood waste, using flash Joule heating. Results indicate an 81-89% reduction in global warming potential compared to traditional disposal methods at a net cost of -$304 per tonne of MSW, presuming the graphene is sold at just 5% of its current market value to offset the cost of the flash Joule heating process.
Modular Synthesis of alpha-Branched Secondary Alkylamines via Visible-light-mediated Carbonyl Alkylative Amination

Published: January 2024

The development of methods for the assembly of alpha-branched secondary alkylamines remains a central challenge to chemical synthesis because of their critical importance in modulating the physical properties of biologically active molecules. Despite decades of intensive research, chemists still rely on selective N-alkylation and carbonyl reductive amination to make most amine products. Here we report the further evolution of a carbonyl alkylative amination process that, for the first time, brings together primary amines, aldehydes and alkyl iodides in a visible-light-mediated multicomponent coupling reaction for the synthesis of a wide range of -branched secondary alkylamines. In addition to exploring the structural tolerance and limitations in each reaction component, we also report preliminary applications to the telescoped synthesis of -branched N-heterocycles and a primary-selective N-alkylation protocol based on carbonyl alkylative amination. We believe that this method will enable practitioners of synthetic chemistry in academic and industrial settings to approach the synthesis of these important molecules in a manner that is distinct from established approaches.

Published: January 2024

The development of next-generation in-memory and neuromorphic computing can be realized with memory transistors based on two-dimensional (2D) ferroelectric semiconductors. Among these, In2Se3 is the most interesting since it possesses ferroelectricity in 2D quintuple layers. However, synthesis of large amounts of In2Se3 crystals with the desired phase has not been previously achieved. We demonstrate here the gram-scale synthesis of α-In2Se3 crystals using a flash-within-flash Joule heating method. This approach allows the synthesis of single-phase α-In2Se3 crystals regardless of the conductance of precursors in the inner tube and enables the synthesis of gram-scale quantities of α-In2Se3 crystals. We then fabricate and use α-In2Se3 flakes as a 2D ferroelectric semiconductor FET artificial synaptic device platform. By modulating the degree of polarization in α-In2Se3 flakes according to the gate electrical pulses, these devices exhibit distinct essential synaptic behaviors. Their synaptic performances show excellent and robust reliability under repeated electrical pulses. Finally, we demonstrate that the synaptic devices achieve an estimated learning accuracy of up to ~87% for Modified National Institute of Standards and Technology patterns in a single-layer neural network system.
Drug Repurposing for Rabies Treatment: A Computational Analysis of 14 Agents
Authors: Hameed Arslan
Published: January 2024

This study explores the repurposing potential of 14 drugs (Emtricitabine, Famciclovir, Acyclovir, Stavudine, Cidofovir, Tinidazole, Ribavirin, Valaciclovir, Nevirapine, Atazanavir, Rilpivirine, Dasabuvir, Raltegravir, Elvitegravir) against the rabies virus glycoprotein pre-fusion trimer complexed with neutralizing antibody RVA122. Using docking and NAMD simulations, a drug ranking system considers key properties (docking score, hepatotoxicity, micro nuclear testing, human intestinal absorption, bioavailability, and blood-brain barrier (BBB) permeability). Excluding drugs with negative BBB (Atazanavir, Rilpivirine, Raltegravir, Elvitegravir), the top five candidates are Emtricitabine, Famciclovir, Acyclovir, Stavudine, and Cidofovir, showing promise for rabies treatment. In vitro and in vivo analyses are imperative for comprehensive validation, including drugs with negative BBB, as alternative mechanisms may contribute to therapeutic efficacy. This approach offers a cost-effective strategy for potential rabies treatment.

Published: January 2024

Sucrose provide sweetness and energy when it binds to both the Venus fly trap domains (VFD) of heterodimeric sweet taste receptor (T1R2/T1R3),1 while non-caloric sweeteners (Sucralose, Aspartame, Neotame, Saccharin, Acesulfame-K (Ace-K), Suosan, SC-45647, Fructose, and D-Tryptophan) bind only at the VFD of T1R2 (VFD2) to provide high-intensity sweetness.2 Here, we address the binding mechanism of various steviol glycosides (Rebaudioside B (RebB), RebM, RebD, Rubusoside (Rubu), RebC), artificial sweeteners (Neohesperidin dihydrochalcone (NHDC), acesulfame K, S-819, Amiloride, and Perillartine), and negative allosteric modulator (Lactisole) at four distinct binding sites, VFD2, VFD3, transmembrane domain 2 (TMD2) and TMD3 by performing binding experiments and computational docking studies. Our docking results find multiple binding sites for the tested ligands including the radio labelled ligands, which provides an explanation of the mixed data of the radio-ligand binding experiments. We predict different preferred binding sites depending on ligand modifications of steviol glycosides. Thus, Rubu binds best at VFD3, while RebB binds best at TMD3, while the others prefer VFD2. We also observed G protein-coupled receptor (GPCR) allostery using the label free Frequency Locking Optical Whispering Evanescent Resonator (FLOWER) method. We show experimentally that the C20 carboxy terminus of the Gα protein can bind to the intracellular region of either TMD2 or TMD3, which can alter GPCR affinity to the high-affinity state for steviol glycosides. These studies provide a mechanistic understanding of the structure and function of this heterodimeric sweet taste receptor that can guide rational structure-based design of novel non-caloric sweeteners aimed at enabling lower sugar usage levels while retaining the sweet taste. This may provide the basis for novel therapeutic applications for treatment of obesity and related metabolic dysfunctions such as diabetes.

Published: January 2024

Spring rice as an alternative to the main season rice has been under major priority of Nepal Government for its huge potential in self-reliance in grain food production and food security in Nepal. Though having higher production and productivity, it was found that its production area had not been scaled up as anticipated. Sowing time is adjusted considering cold stress and pre-monsoon rainfall. Seedlings are generally raised in wet bed and dry bed nurseries based on availability of spring water and 30-40 days seedlings are transplanted in the Nepali month of Chaitra (Mar/Apr). Water being crucial during the growth stages of rice plant, water level of 2-5 cm is found to have better yield and performance. Whereas mainly 16 elements including both micro and macro elements have been required for proper growth and development of rice which were mainly supplied through FYM, compost, urea and DAP. Various cultural, mechanical and chemical methods are found for management of weeds. Similarly, IPM approach as well as modern approaches like gene manipulation, resistant varietal development have been evolving instead of solely pesticides application for better protection of spring rice crop in the present context.
A REVIEW ON INTEGRATED MANAGEMENT OF COTTON AND SUGARCANE PEST
Authors: Ghimire Anup
Published: January 2024

Various insect pests can damage crops to different extents, reducing both their quality and quantity. Cotton and sugarcane are particularly vulnerable to sucking complex pests and borer complex pests, which cause damage in different ways. Complex pest sucking sap from delicate plant components, while borer complex pests bore into the crop. These pests have the potential to cause significant damage to the agricultural sector, leading to a considerable loss in yield and quality. The haphazard use of insecticides and pesticides to manage these pests has become a global problem, resulting in harmful effects on human health, plant systems, and the environment. To regulate pest populations, different integrated pest management techniques are followed, including physical, mechanical, cultural, and biological methods. These strategies, which are both sustainable and environmentally sound, attempt to keep pest populations below the economic threshold level. This paper gives an introduction to the invasive pest, biology, lifecycle, and integrated management of cotton and sugarcane pests.
EFFECTS AND MANAGEMENT PRACTICES OF HEAT STRESS IN MAIZE (ZEA MAYS L.): A REVIEW
Authors: Poudel Mithun , Poudel Mukti Ram , Dhungana Binu
Published: January 2024

A vital crop in various agro-ecological regions, Maize (Zea mays L.) ranks second only to rice in terms of cultivation in Nepal. Although Maize is considered heat resistant, exposing it to the temperature exceeding 37-degree Celsius results in the heat stress reducing its productivity. Threat of global warming is real with the changing climate, studies indicate future heat waves will likely be more severe and persistent, negatively impacting the productivity. Reduced plant height, decreased leaf area, and delayed flowering are some of the consequences of heat stress in maize plants. It disrupts photosynthetic efficiency, damaging photosynthetic machinery, reducing enzyme activity, and impairing chloroplast functioning. Furthermore, heat stress induces ROS causing cell membrane damage, disruption of enzymatic activities, ultimately resulting in stunted plant growth and productivity. During the flowering stage, heat stress reduces the number of florets, impairs silk and grain development, and promotes premature senescence, leading to a shorter plant lifespan and decreased grain yield. Early sowing of maize, effective irrigation and nutrient management can help reduce soil temperature, enhance water use efficiency and minimize heat stress. The adoption of heat-resistant maize varieties and improved breeding techniques is also essential for mitigating the adverse effects of heat stress in maize cultivation. This paper addresses the consequences of heat stress on maize, including effects on growth, photosynthetic characteristics, reactive oxygen species (ROS), reproductive development, premature senescence, and overall grain yield while also exploring strategies for mitigating the impacts of heat stress on maize through agronomic practices and breeding.

Published: January 2024

This study aims to economically evaluate the water use efficiency at three rates of irrigation (1, 2, and 3) with the comparison between using 11.9 ton ha-1 application rate of the biochar and/or compost along with the mineral fertilization on the yield and quality of the faba bean crop. Two field experiments were conducted at El-Qantara Sharq farm Ismailia Governorate, Egypt, (winter seasons of 2020/2021 and 2021/2022) in a split-plot design with three replicates. The main factor F1 was the irrigation rates: rate 1 (3571.43 m3 ha-1), rate 2 (4761.90 m3 ha-1), and rate 3 (5952.38 m3 ha-1) while the sub-factor F2 was the type of the soil additive (biochar, compost or mineral). The soil-available N (mg kg-1) has increased relative to that before cultivation in the range 11.3 – 55.5% that was non-significant due to the irrigation rates (main factor F1) but a significant due to the soil additives (sub-factor F2). The studied irrigation rates as well as the soil additives have increased the soil-available concentration (mg kg-1) of K, Mn, and Zn significantly and the available P, and Fe but non-significantly at p < .05. The most significant relative increase compared to the soil-available content (mg kg-1) before cultivation was found for the compost at the irrigation rate 3 by 6.9% for K, 78.3% for Mn, and by 44.1% for Zn. The increase in the available nutrients followed the order irrigation rate 1 (3571.43 m3 ha-1) < rate 2 (4761.90 m3 ha-1) < rate 3 (5952.38 m3 ha-1) and the order mineral < biochar < compost. The increased yield (ton ha-1) of pods and seeds at the rate 3 relative to rate 1 was by 6.1% and 28.4% for the mineral fertilization, by 11.6% and 13.4% for the biochar, and by 15.0% and 26.1% for the compost, respectively. This increase was dependent on both factors F1 and F2 since their interaction was highly significant. At the irrigation rate 3, the total costs increased in the direction biochar (13095 LE) < compost (13333 LE) < mineral (14404 LE). The maximum net return was at the irrigation rate 2 for the compost (36837 LE) followed by the biochar (34010 LE) then at the rate 3 for the mineral fertilization (28326 LE). The return and net return with respect to the costs were also increased in the same order: rate 2 (compost) > rate 2 (biochar) > rate 3 (mineral). The application of the compost and/or the biochar is more efficient at the rate 2 than the single use of the mineral fertilization that need greater level of the irrigation water otherwise the yield decreases. The maximum water unit return has increased by 32.3% and 21.9% for the compost and biochar at rate 2, respectively, relative to the mineral at rate 1.

This paper investigates a suitable model capable of planning a better global system for mobile communication (GSM) network (MTN) with a view to address numerous complain of poor quality service by the subscribers, within Sokoto city using measuring tape, Basic Transreceiver System (BTS) app on mobile phone and mobile device distance. Received Signal Strength (RSS) were obtained from MTN base stations (network) located in State and path loss was analyzed. The experimental measurement of path loss was compared to theoretical models of COST231 and Hata models. The results showed that the COST231 was found most suitable path loss prediction model for Sub-urban region of Sokoto based on the validation test; however, the Hata model also produces reasonable estimates and can be use for path loss prediction model in the location.

Published: January 2024

This study establishes mathematically a comprehensive approach for evaluating the solutions of Bessel’s function of the first kind for different values of the order n. The study revealed that the knowledge of gamma function, Maclaurin’s series and basic laws of indices plays a significant role in evaluating the Bessel’s function of order n. The results showed that the solutions, J-1(x) = J-2(x) = J-3(x) = 0 for x = 0, 1, 2, 3, 4…….12; the pattern of variation for the various graphs of J0(x), J1/2(x), J-1/2(x), J1(x), J3/2(x), J-3/2(x), J2(x), J5/2(x), J-5/2(x) and J3(x) were investigated and the results showed that there is a slight decrease in the values of J0(x) from x = 0 to 3 which then increase steadily from x = 4 to 12, for J1/2(x), J3/2(x), J2(x) and J3(x), the values increases from x = 0 to 12. The values of J-1/2(x) increases steadily from x = 0 to 12 in the form of a parabola. For J1(x), the graph increase from x = 0 to 2 then decreases at x = 3 and increases continuously from x = 4 to 12. The figure depicting J-3/2(x) showed that when x = 0, J-3/2(0) = ∞ , negative values were obtained at x = 1 and 2, the values then increases steadily from x = 4 to 12. The figure for J5/2(x) shows that the values increases from x = 0 to 2 and decreases negatively from x = 3 to 8 and increases steadily from x = 9 to 12. The figure for J-5/2(x) depicts that when x = 0, J-5/2(0) = ∞, the values decrease from x = 1 to 2 and decreases further but negatively from x = 3 to 12.

Published: January 2024

The study presents how to obtain the solutions of the n^th-order ordinary differential equations with varying delay proportional to the independent variable, where n belongs to the set of natural number, ℕ. These are equations that are often used in Mathematics to characterize real life problems such as optimizing profits, minimizing costs, and improving individuals’ health. Economic models can help to understand and predict the economic behaviours of different countries. The results of this study are applied to certain economic models. Under the assumption that the market is in equilibrium, the study considers price adjustment models and proposes an adjustment model by introducing a proportional delay into the formulation, which improves the suitability of the models. The study displays the solutions of the models by using Matlab to present their graphs and compare them.

This survey assessed the direct effects of teaching quality, teaching competence and mathematics connection on mathematics achievement motivation in Senior high School students in Ghana. A descriptive survey was used in the study, which included 329 senior high school students from Barekese Senior High School. Prior to the main model estimation, preliminary studies such as Confirmatory Factor Analysis, convergent validity, discriminant validity, and internal consistency (Cronbach’s Alpha) were computed. Amos (v.23) was used to do structural equation modeling (SEM) in order to assess the various assumptions. The results of path estimations revealed that mathematics connection positively and significantly influenced mathematics achievement motivation. However, teaching quality and teaching competence has no significant impact on mathematics achievement motivation.
Aspergillus Sensitisation and Severe Asthma Clinical Outcomes

Published: January 2024

Fungal lung diseases represent a heterogenous group of conditions and the differing definitions are used to describe these relationships. Historically there has been the nomenclature evolution on the spectrum of lung diseases linked to sensitisation to A. Fumigatus including SAFS (severe asthma with fungal sensitisation) and ABPA/M (allergic bronchopulmonary aspergillosis/mycosis). It seems that AFAD (airway fungal airway disease) therefore represents an open definition of IgE sensitisation to thermotolerant fungi. It covers not only the most severe forms of the disease as SAFS and ABPA, but also milder forms of airway disease. It might represent a treatable trait which has to be seen, longitudinally observed, and treated and consequently preventing lung damage.

Induced sputum is a method which, by inhaling hypertonic saline, provoke a person to expectorate certain amount of bronchial secretion. Sputum sample obtained consists of liquid and celullar phase. It is used over the years to investigate airway inflammation in patients with asthma and chronic obstructive pulmonary disease (COPD). Results of cell counts in induced sputum is essential in differentiation of airway eosinophilia or neutrophilia or both, or a determination of paucigranulocytic phenotype. Obtained severe asthma phenotype due to airway inflammation help us to select biological therapy and predict responders. The correlation between “noninvasive” measures such as blood eosinophilia, or fraction of exhaled nitric oxide (FeNO) with sputum eosinophils is suboptimal. Induced sputum is a good and reproducible discriminator for eosinophilic asthma. There asre some safety concerns as induced sputum procedure can provoke adverse effects such as bronchoconstriction and dyspnea, which is reversible to standardized therapy. Sputum induction is safe and well tolerated by patients with severe asthma, which supports its use in clinical and research practice.

Published: January 2024

Background: BK polyomavirus that is acquired in early childhood as BKPyV is near ubiquitous in adults with a seroprevalence of >80%, it has been found as the main cause of hemorrhagic cystitis in hematopoietic stem cell transplantation patients, due to immunosuppression regimen that lead to the activation of the virus from the latency status and lead to increased viral shedding in urine (viuria). Objective: To investigate the frequency of BK Polyomavirus antigen excretion in urine of children with acute lymphoblastic leukemia with and without chemotherapy and compare it with normal controls. Patients and Methods: A case-control study conducted from December 2021 to May 2022 in Baghdad, Iraq on leukemia patients of Central Pediatrics Hospital (Al-Eskan ). Urine samples and urine sediment smears were collected from 60 acute lymphoblastic leukemia patients. And compared with 60 apparently healthy age and sex-matched children, BK polyomavirus antigen in urine was detected using Enzyme-linked Immunosorbent Assay and urine cytology were Pap stained for the detection of decoy cells (DCs). Results: Positive BKPyV antigen in urine was seen in 55 (91.7%) of Acute lymphoblastic leukemia patients and 39 (65.0%) in controls (p=<0.001) and all the patients were decoy negative. There was no significant effect of the positivity of antigenuria on neither leukocytes level nor on the occurance of relapse in leukemia patients. Conclusion: The very high frequency of BKPyV in the urine signifies the importance of reactivation of this virus in ALL patients with and without chemotherapy.
