Abstract

Background: Spatial Repellents (SRs) have been widely used for the prevention of mosquito bites, and preliminary findings suggest efficacy against both malaria (1) and Aedes-borne viruses (2)but their effectiveness in reducing mosquito borne diseases under operational use has never been evaluated. SRs have the potential of being critical tools in the prevention of mosquito borne diseases in contexts where typical vectors control strategies, such as Insecticide-Treated Nets (ITNs) and indoor residual spraying, are inaccessible or underutilized such as among displaced persons or in emergency relief settings.
Methods: Children will be enrolled in 3 separate cohorts to establish effectiveness of SRs in reducing malaria infection in different distribution channels. One cohort will estimate the direct effect of the SR distributed through a reference channel (study personnel distribution). The two remaining cohorts will estimate the protection of the SR distributed through a voucher channel and Village Health Team channel. Cohorts will be followed twice a month (approximately every 15 days): during the first scheduled household visit in the month, a blood sample will be taken for malaria rapid diagnostic test (Monthly Visit #1); and, during the second scheduled household visit, a blood sample will only be taken if the participant has a recent history of fever (Monthly Visit #2). The incidence of malaria in each cohort will be estimated and compared to the reference cohort to determine the benefit of using a SR in an area with high, year-round transmission of malaria.
Discussion: This study will address the knowledge gap of whether or not SRs are effective in reducing human malaria disease in humanitarian assistance and emergency response settings in sub-Saharan Africa where underlying transmission rates are historically high and ITNs may or may not be widely deployed. This research will inform policy makers on whether to recommend SRs as a means to further reduce malaria transmission for such operational programs.

Abstract

Background: Botulinum toxin type A (BoNT) is a well-established therapeutic modality for the treatment of lower limb spasticity in children with cerebral palsy.
Objective: To assess the functional outcomes and tolerability of BoNT injection for the treatment of lower limb spasticity in children with neurometabolic/genetic disorders.
Methods: We conducted a retrospective chart review for history, demographic data, comorbidities, neurological examination, and neuroimaging findings for all patients diagnosed with neurometabolic/genetic disorders from December 2020 to December 2022. The outcomes were assessed by recording the Gross Motor Function Classification system (GMFCS) for Cerebral Palsy "Initially and after 6 months' post-treatment", the Modified Ashworth scale (MAS) "initially and at 1,3,6 month post-treatment" and the achieved preset functional goals using the Goal Attainment Scaling (GAS) at 4-6 months post-treatment.
Results:
A total of 90% of the patients showed improvement in their GAS scores, with 20% achieving the preset goal, 55% achieving a better outcome than anticipated and 15% achieving the best possible outcome. Furthermore, the GMFCS and MAS scores showed a significant statistical improvement after six months post-injection (p=0.02, p=0.03), respectively. None of the patients developed serious adverse effects except one who had mitochondrial cytopathy.
Conclusion:
BoNT injections were effective and showed a high safety profile in children with neurometabolic/genetic disorders. To our knowledge, this is the first study that specifically targets this patient population, filling a gap in the literature and providing valuable insights into the potential benefits of BoNT injections for this group. However, further large-scale studies are recommended to confirm these findings.
Comprehensive assessment of heavy metal leaching behavior and environmental risk from antimony mine tailings

Published: July 2024

Abstract

A large amount of abandoned antimony tailing slag piled up in the open air has been released and migrated to the surrounding environment under the weathering and leaching effects, causing heavy metal pollution. The evaluation of heavy metal contamination of antimony tailings slag is essential. In this study, the indices Igeo, Cf, and Er were used to evaluate the risk of heavy metal contamination of slag from an open antimony mine tailings pile in southwest China. These indices were weighted to produce a composite evaluation reflecting the level of risk of heavy metal contamination as:PERs(Sb)>PERs(As)>PERs(Zn)=PERs(Cd)>PERs(Ni)>PERs(Pb)>PERs(Cr)>PERs(Cu). To verify the accuracy of the comprehensive evaluation results, an experimental study was carried out on slag samples using static leaching experiments. The results indicate that the exact amount of release is related to its release mechanism and that it was found to be more accurate for the combined evaluation of Sb, Zn, and Ni. Additionally, water samples were evaluated using principal component analysis to refine the comprehensive evaluation. Ni and Zn contamination was also found to be of concern. Furthermore, this study highlights an optimization methodology for heavy metal pollution risk evaluation.

Abstract

Background With increasing labor challenges, achieving complete mechanization in cotton cultivation has become an urgent necessity in India. For mechanized cotton cultivation, it is necessary to have appropriate variety with designed canopy architecture. The required canopy architecture with higher seed cotton yield may be attained through optimizing crop geometry and spraying of plant growth regulators like mepiquat chloride. Also, application of mepiquat chloride alters canopy architecture in cotton by creating a more compact canopy suited for mechanization. In this study, we have optimized the different crop geometries and also studied the growth and yield potential of different desi varieties viz., CO 17, VPT 2 and Suraksha with respect to plant growth regulators. This study mainly deals with growth, physiology, dry matter production and yield of each compact cultivars by application of plant growth regulators grown under diverse spatial patterns.Results Among the three varieties tested, Suraksha variety significantly recorded optimum plant height, accumulated more dry matter in fruiting bodies, produced more sympodial branches and boll numbers per plant, and higher seed cotton yield compared to CO 17 and VPT 2 varieties. Increased plant densities significantly increased the dry matter production because of higher plant population per unit area. However, wider spacing of 90 cm significantly recorded greater plant height, more sympodial branches and boll numbers per plant, and seed cotton yield compared to narrow spacing of 70 cm. The combined application of mepiquat chloride with cyclanilide @ 400 ppm at square initiation and boll development stages had significantly increased the sympodial branches and number of bolls per plant, accumulated more biomass content in fruiting bodies and increased seed cotton yield, whereas application of mepiquat chloride alone accumulated more biomass content in vegetative parts and recorded greater plant height, and internodal distance.Conclusion Suraksha variety sown under spacing 90 x 15 cm and treated with mepiquat chloride with cyclanilide @ 400 ppm at square initiation and boll development stages resulted in higher number of bolls per plant, boll weight and seed cotton yield under mechanized cultivation. This combination also produced a desired plant architecture suitable for mechanical harvesting.

Published: July 2024

Abstract

Objective: Kangduo (KD) surgical robot is a novel robotic system in China, and some animal experiments and single-arm clinical trials have indicated its effectiveness, feasibility, and safety for urologic surgeries. This study intended to compare the performance and safety of the KD surgical robot with the da Vinci (DV) robotic system in patients who received urologic surgeries.
Methods: A total of 201 patients who received urologic surgeries were divided into the KD group (N=60) and the DV group (N=141) according to the actual surgical methods.
Results: The median (range) operation time [180.0 (30.0-540.0) minutes vs. 130.0 (70.0-360.0) minutes] (P<0.001) and indwelling time of abdominal drainage tube [5.0 (2.0-14.0) days vs. 3.0 (2.0-18.0) days] (P<0.001) were longer, but the intraoperative blood loss [50.0 (10.0-200.0) mL vs. 50.0 (10.0-400.0) mL] (P<0.001) was less in the KD group than the DV group. The median values of white blood cells at the 1st (P=0.032) and 3rd (P=0.022) day after surgery were decreased in the KD group compared to the DV group. The incidence of infection (11.7% vs. 29.1%) (P=0.008) and fever (15.0% vs. 30.5%) (P=0.023) was lower in the KD group compared to the DV group. Postoperative and follow-up parameters, including time of uracratia improvement, administration of hemostatic, pain numeric rating scale score, Barthel’s index score, and patient satisfaction, were not different between the two groups (all P>0.05).
Conclusion: The KD surgical robot unveils satisfactory surgical performance compared to the DV robotic system in patients receiving urologic surgeries.

Abstract

Sweetpotato, Ipomoea batatas (L.) Lam. (2n = 6x = 90), is among the world’s most important food crops and is North Carolina’s most important vegetable crop. The recent introduction of Meloidogyne enterolobii poses a significant economic threat to North Carolina’s sweetpotato industry and breeding resistance into new varieties has become a high priority for the US sweetpotato industry. Previous studies have shown that ‘Tanzania’, a released African landrace, is resistant to M. enterolobii. We screened the biparental sweetpotato mapping population, ‘Tanzania’ x ‘Beauregard’, for resistance to M. enterolobii by inoculating 246 full-sibs with 10,000 eggs each under greenhouse conditions. ‘Tanzania’, the female parent, was highly resistant, while ‘Beauregard’ was highly susceptible. Our bioassays exhibited strong skewing toward resistance for three measures of resistance: reproductive factor, eggs per gram of root tissue, and root gall severity ratings. A 1:1 segregation for resistance suggested a major gene conferred M. enterolobii resistance. Using a random-effect multiple interval mapping model, we identified a single major QTL, herein designated as qIbMe-4.1, on linkage group 4 that explained 70% of variation in resistance to M. enterolobii. This study provides a new understanding of the genetic basis of M. enterolobii resistance in sweetpotato and represents a major step towards the identification of selectable markers for nematode resistance breeding.
Evaluating the Impact of Water-Cement Ratios on the Compressive Strength and Water Absorption of Coal Bottom Ash Concrete
Authors: Meh Ku Muhammad Firdaus Ku , Omar Zaim 
Published: July 2024

Abstract

Coal Bottom Ash (CBA) is an industrial byproduct generated in significant quantities due to increased power consumption. Utilizing CBA as a sand replacement in concrete is considered a promising innovation for producing environmentally friendly concrete. However, determining the precise water-cement (WC) ratio is challenging due to the highly porous nature of CBA. This study examines the impact of WC ratio on the compressive strength and water absorption of CBA concrete. Concrete samples with WC ratios of 0.40, 0.45, and 0.50, incorporating 0%, 10%, and 20% CBA replacement, were evaluated. Results indicated that an increase in both CBA percentage and WC ratio led to a decrease in compressive strength and an increase in water absorption. However, with extended curing periods, compressive strength improved, and water absorption decreased. The target strength of CBA concrete was achievable with up to 20% CBA and a WC ratio between 0.40 and 0.45. A significant correlation between compressive strength and water absorption was identified for WC ratios of 0.40 and 0.45, as evidenced by the correlation coefficient (R2). Conversely, the R2 value for a WC ratio of 0.50 showed no clear relationship between these factors.
The Role of Digital Finance on FDI inflow: Facilitator or Inhibitor?
Authors: Jiang Min , Zhou Wei , Zong Jiani 
Published: July 2024

Abstract

Digital finance, as an innovative form of financing, has a distinct impact on FDI inflow compared to traditional finance. This paper provides a theoretical analysis of the impact of digital finance on FDI inflow from both supply-side and demand-side perspectives. Based on data from prefecture-level cities in China, this study reveals the significant role of digital finance in facilitating FDI inflow. The advancement of digital finance not only enhances financial market efficiency and attracts foreign investments through its financial effects but also stimulates regional innovation, entrepreneurship, and consumer spending, resulting in increased FDI inflow due to its economic effects. The comparative analysis suggests that traditional financial development impedes FDI inflow. Traditional finance can alleviate its inhibitory effect on FDI inflow by promoting innovation and entrepreneurship, but it lacks financial effects and cannot attract FDI by expanding the consumer market. The divergent roles of these two financial forms may be attributed to China's traditional finance focusing on scale expansion, while digital finance enhances financial efficiency for qualitative development.

Published: July 2024

Abstract

Multidrug resistance in Escherichia coli has become a concerning issue for humans worldwide. Currently, scientists are considering the use of bacteriophages in medicine as a promising alternative to antibiotics. The aim of this study was to screen for, isolate, and characterize a novel bacteriophage with confirmed lytic activity against multidrug-resistant (MDR) E. coli. A clinical MDR E. coli strain was selected among 65 isolates and identified by the VITEK2 system, and the disc diffusion method was utilized to evaluate the antibiotic sensitivity profile. A bacteriophage, designated ɸEcM-vB1, was isolated from sewage water via the enrichment method and double agar overlay technique. The lysis profile of the isolated phage against MDR E. coli was evaluated by a spot test. Transmission electron microscope was used to determine phage morphology. The growth kinetics (latent period and burst size), genomic analysis and total protein content were determined. ɸEcM-vB1 bacteriophage exhibited high lytic activity against different MDR E. coli isolates and maintained relatively high activity under broad environmental conditions of temperature (40–60°C) and in a wide pH range (3–11). It belongs to the Myoviridae family of the caudovirales order. Single-step growth curve analysis revealed that the latent period of our phage was 10 minutes, and its average burst size was 271.72 pfu/cell. Genomic analysis revealed that ɸEcM-vB1 contains dsDNA, which is susceptible to digestion by EcoRI. Ten structural proteins were detected by SDS‒PAGE. ɸEcM-vB1 is considered a promising candidate for phage therapy applications.
