Lymnaeid snails are vital in transmitting trematode cercariae as an intermediate host that can infect buffalo and other ruminants and humans, causing significant economic losses. The study aimed to conduct morphological and molecular identification of snails and cercariae collected from the selected buffalo farms under palm oil integration in Perak, Malaysia. A cross-sectional study was conducted, and 35 water were investigated for the presence or absence of snails. A total of 836 lymnaeid snails were collected from three marshes wetlands. To identify the snail family and species, morphological identification was performed on each snail’s shell, and to identify trematode cercariae types; the crushing method was used to observe the cercarial stage inside each snail’s body. In addition, the Internal Transcribed Spacer 2 (ITS2) region and Cytochrome c oxidase subunit 1 (cox1) was used as the target gene to identify the snail species and cercarial types up to the species level. The result showed that the collected snails belong to the family Lymnaeidae and Radix rubiginosa species. The infection rate by cercarial emergence in snails was 8.73%. Five morphological cercarial types were observed which include: echinostome, xiphidiocercariae, gymnocephalous, brevifurcate-apharyngeate distome, and vivax. Using molecular methods, the identified cercariae belong to the three families, including Echinostomatidae, Plagiorchiidae, and Fasciolidae. This is the first report on R. rubiginosa and different types of trematodes cercariae in buffalo farms under palm oil integration in Perak. Our finding confirmed that R. rubiginosa could serve as an intermediate host for a range of parasitic trematodes in Perak.

Background To evaluate the safety and efficacy of autologous bone marrow mononuclear cell (BMMNC) infusion in the management of neurological sequelae in children with spina bifida (SB). Methods BMMNCs were harvested from bilateral anterior iliac crests. Two intrathecal BMMNC administrations were performed with an interval of 6 months. The measurements of outcomes included clinical assessments, cystomanometry and rectomanometry. Results Eleven children with SB underwent autologous BMMNC infusions from 2016 to 2020. There were no severe adverse events during the study period. The number of patients requiring assistance to expel stools decreased from 11 before cell infusion to 3 after the second cell infusion. The number of patients who had urine leakage decreased from 9 patients at baseline to 3 patients after the second BMMNC infusion. The mean bladder capacity increased from 127.7 ± 59.2 ml at baseline to 136.3 ± 54.8 ml at six months and to 158.3 ± 56.2 ml at 12 months after BMMNC infusions. Detrusor pressure (pdet) decreased from 32.4 ± 22.0 cm H2O at baseline to 21.9 ± 11.8 cm H2O after 12 months of follow-up. At baseline, six patients could walk independently. After the 2nd infusion, eight patients could walk independently. Conclusion Intrathecal infusions of autologous bone marrow mononuclear cells are safe and may improve bowel, bladder, and motor function in children with SB. Trial registration: NCT, NCT05472428. Registered July 25, 2022- Retrospectively registered, https://www.clinicaltrials.gov/ct2/show/NCT05472428.

Foodborne zoonotic trematode (FZT) infections are common neglected tropical diseases in Southeast Asia. Their complicated life cycles involve freshwater snails as intermediate hosts. A cross-sectional study was conducted in Yen Bai and Thanh Hoa provinces in North and Central Vietnam, to investigate the diversity of cercariae of potential FZT and to construct the phylogenetic relationship of trematode cercariae based on the Internal Transcribed Spacer 2 (ITS2) region. Among 17 snail species collected from various habitats, 13 were infected by 10 cercarial groups among which parapleurolophocercous, pleurolophocercous, and echinostome cercariae were of zoonotic importance. The monophyletic tree separated cercarial sequences into different groups following the description of the cercariae families in which Haplorchidae, Opisthorchiidae, Echinochasmidae, and Echinostomatidae are important families of FZT. The overall prevalence was different among snail species and habitats and showed a seasonal trend. Parapleurolophocercous and echinostome cercariae emerged as the most common cercariae in snails in Yen Bai, while monostome, echinostome, and megalura cercariae were most common in Thanh Hoa. Using a molecular approach, we identified Parafossarulus striatulus as the first intermediate snail host of Clonorchis sinensis in Thac Ba Lake. Melanoides tuberculata and Bithynia fuchsiana were we identified preferred intermediate snail hosts of a diverse range of trematode species including intestinal flukes (i.e., Haplorchis pumilio and Echinochasmus japonicus) in Yen Bai and Thanh Hoa, respectively.

A high prevalence of mental disorders in adolescents has been reported worldwide, but little is known about mental health literacy in this population, particularly in developing countries. The goal of this study was to evaluate mental health literacy level and help-seeking preferences in high school students in Ho Chi Minh City, Vietnam. These two variables were also compared between students who had stress, anxiety and depression with students who did not. A cross-sectional study was conducted with 1094 students across 27 classes at three high schools. Students completed a self-report questionnaire that included validated scales such as the Depression Anxiety Stress Scale (DASS-21), the Mental Health Literacy Scale (MHLS) and the General Help-Seeking Questionnaire. Based on the DASS-21, the prevalence of students reporting symptoms of stress, depression and anxiety was 36.1%, 39.8% and 59.8%, respectively. The mean MHLS score was 104.12 (SD = 10.09) and was significantly lower in students who had symptoms of depression. The most common help-seeking preferences for mental illness were friends, classmates and relatives or family members. Help-seeking preferences were almost identical among students with stress, anxiety or depression. While Vietnamese high school students had high levels of symptoms of stress, depression and anxiety and moderate levels of mental health literacy, non-professionals were preferred as their first help-seeking choice. Our findings revealed the need for routine school-based mental health screening and referral activities as well as mental health education programs for high school students in Vietnam.

Fe2O3 nanoparticles were synthesized from iron nitrate [Fe(NO3)3·9H2O] by hydrothermal method for Fe-air battery anodes. The crystal structure and morphology of the obtained Fe2O3 powder were studied by x-ray diffraction and scanning electron microscopy. Fe2O3/acetylene black (AB) composite electrodes were fabricated by mixing the synthesized Fe2O3 nanoparticles with AB carbon and were then subjected to electrochemical measurements. Results indicated that the duration of hydrothermal treatment significantly influences the morphology and size of synthesized Fe2O3. The morphology and particle size of Fe2O3 also affect the electrochemical properties of Fe2O3/AB composite electrodes, viz., smaller particles provide greater capacity than larger ones. The resistance of electrodes gradually increases during cycling, thereby causing a decrease in the capacity of Fe2O3/AB electrodes.

Horizontal displacement of hydropower dams is a typical nonlinear time-varying behavior that is difficult to forecast with high accuracy. This paper proposes a novel hybrid artificial intelligent approach, namely swarm optimized neural fuzzy inference system (SONFIS), for modeling and forecasting of the horizontal displacement of hydropower dams. In the proposed model, neural fuzzy inference system is used to create a regression model whereas Particle swarm optimization is employed to search the best parameters for the model. In this work, time series monitoring data (horizontal displacement, air temperature, upstream reservoir water level, and dam aging) measured for 11 years (1999–2010) of the Hoa Binh hydropower dam were selected as a case study. The data were then split into a ratio of 70:30 for developing and validating the hybrid model. The performance of the resulting model was assessed using RMSE, MAE, and R 2. Experimental results show that the proposed SONFIS model performed well on both the training and validation datasets. The results were then compared with those derived from current state-of-the-art benchmark methods using the same data, such as support vector regression, multilayer perceptron neural networks, Gaussian processes, and Random forests. In addition, results from a Different evolution-based neural fuzzy model are included. Since the performance of the SONFIS model outperforms these benchmark models with the monitoring data at hand, the proposed model, therefore, is a promising tool for modeling horizontal displacement of hydropower dams.

Satellite remote-sensing products with high spatial and time resolution are expected to provide alternative data sources for data-sparse regions. This study clarifies if the satellite–gauge product outperforms the satellite-only product by comparing remote-sensing precipitation products: one that incorporates rain gauge data (GSMaP-Gauge) and one that uses satellite only (GSMaP-MVK). The appropriateness of those two commonly used high-resolution products as the input to the conceptual hydrological model Hydrologiska Byråns Vattenbalansavdelning for stream flow prediction was also investigated. In addition, we also analyzed the deviations of model parameters due to the bias in remote-sensing precipitation inputs compared to standard ground measurements. The results indicated that GSMaP-Gauge was superior, with satisfactory to good performances in predicting stream flow in both temperate and subtropical basins (Hyeonsan, Fuji, and Da). However, its performance was slightly worse than GSMaP-MVK in the Upper-Cau basin, which was explained by the poor quality of the adjusted data source due to sparse data and the satellite–gauge blending algorithm of GSMaP-Gauge. Better parameter agreements with the observations of GSMaP-Gauge than GSMaP-MVK were found in the Hyeonsan and Da river basins where GSMaP-Gauge showed almost consistent relationship of monthly rainfall compared to ground measurements.

The development of a sensitive and rapid diagnostic test is needed for early detection of avian influenza (AI) H7 subtype. In this study, novel monoclonal antibodies (mAbs) against influenza A H7N9 recombinant hemagglutinin (rHA)1 were developed and applied to a Europium nanoparticle–based rapid fluorescent immunochromatographic strip test (FICT) to improve the sensitivity of the rapid diagnostic system. Two antibodies (2F4 and 6D7) exhibited H7 subtype specificity in a dot-FICT assay by optimization of the conjugate and the pH of the lysis buffer. The subtype specificity was confirmed by an immunofluorescence assay and Western blot analysis. The limit of detection of the FICT employing novel mAbs 31 ng/mL for H7N9 rHA1 and 40 hemagglutination units/mL for H7 subtype virus. Sensitivity was improved 25-fold using Europium as confirmed by comparison of colloidal gold-based rapid diagnostic kit using the 2F4 and 6D7 mAbs.

Background Bruchid beetles are an important storage pest of grain legumes. Callosobruchus sp. infect mungbean (Vigna radiata) at low levels in the field, multiply during grain storage and can destroy seed stocks in a few months. Resistance against bruchid beetles has been found in wild mungbean V. radiata var. sublobata TC1966 and in cultivated mungbean line V2802. Results Bruchid resistance data were obtained from recombinant inbred line populations TC1966 (V. radiata var. sublobata) × NM92 (F12) and V2802 (V. radiata) × NM94 (F7). More than 6,000 single nucleotide polymorphic markers were generated through genotyping by sequencing (GBS) for each of these populations and were used to map bruchid resistance genes. One highly significant quantitative trait locus (QTL) associated with bruchid resistance was mapped to chromosome 5 on genetic maps of both populations, suggesting that TC1966 and V2802 contain the same resistance locus. Co-segregation of all markers associated with resistance indicated the presence of only one major resistance QTL on chromosome 5, while QTL analysis based on physical map positions of the markers suggested the presence of multiple QTLs on different chromosomes. The diagnostic capacity of the identified molecular markers located in the QTL to correctly predict resistance was up to 100 %. Conclusions Molecular markers tightly linked to bruchid resistance loci of two different mungbean resistance sources were developed and validated. These markers are highly useful for developing resistant lines.
