"abstract": "Expansive pedicle screws significantly improve fixation strength in osteoporotic spines. However, the previous literature does not adequately address the effects of the number of lengthwise slits and the extent of screw expansion on the strength of the bone/screw interface when expansive screws are used with or without cement augmentation. Herein, four designs for expansive pedicle screws with different numbers of lengthwise slits and different screw expansion levels were evaluated. Synthetic bones simulating severe osteoporosis were used to provide a comparative platform for each screw design. The prepared specimens were then tested for axial pullout failure. Regardless of screw design, screws with cement augmentation demonstrated significantly higher pullout strength than pedicle screws without cement augmentation (p < 0.001). For screws without cement augmentation, solid screws exhibited the lowest pullout strength compared to the four expansive groups (p < 0.01). No significant differences in pullout strength were observed between the expansive screws with different designs (p > 0.05). Taken together, our results show that pedicle screws combined with cement augmentation may greatly increase screw fixation regardless of screws with or without expansion. An increase in both the number of slits and the extent of screw expansion had little impact on the screw-anchoring strength. Cement augmentation is the most influential factor for improving screw pullout strength.",

"abstract": "\nLas democracias contemporáneas afrontan un desafío filosófico de primera magnitud: la colonización algorítmicamente mediada de la deliberación pública, la formación epistémica y la identidad cívica por sistemas cuya lógica opera de manera opaca, asimétrica y orientada a la optimización de comportamientos antes que al fortalecimiento democrático. Este artículo propone la Responsabilidad Prospectiva Ciudadana (RPC) como categoría filosófica original para conceptualizar la ciudadanía ética activa en sociedades algorítmicamente mediadas. A partir de una revisión sistemática de 127 artículos arbitrados identificados en dos bases de datos complementarias — Web of Science (A&HCI + SSCI, n = 77) y Scopus (ARTS / SOCI / COMP, n = 50) — mediante 12 ecuaciones de búsqueda para el período 2015-2026, e integrando seis tradiciones filosóficas (Jonas, Habermas, Rawls, Mouffe, Fricker y Floridi) con los marcos de democracia contestataria y poder constituyente de Mejía Quintana, Lefort, Rosanvallon y Abensour, el artículo demuestra que la literatura especializada ha producido un diagnóstico extraordinariamente sofisticado de las transformaciones algorítmicas (70% del corpus, Ejes 1-4) mientras deja dramáticamente subdesarrollada la respuesta filosófica normativa desde la perspectiva del ciudadano ordinario (30%, Ejes 5-8). El proceso de deduplicación sistemática eliminó 126 registros duplicados (96 entre bases WoS-Scopus, 29 internos de Scopus, 1 interno de WoS) de los 2.483 registros identificados, obteniendo 2.357 registros únicos para cribado. Se derivan seis principios normativos del análisis filosófico integrado: transparencia algorítmica (P1), explicabilidad y derecho de impugnación (P2), equidad epistémica (P3), participación en la gobernanza (P4), solidaridad informacional (P5) y resistencia informada (P6). Estos principios tienen implicaciones directas para el diseño de innovaciones democráticas en contextos digitales polarizados, incluidos el AI Act europeo, las recomendaciones de ética de la IA de la UNESCO y los procesos democráticos participativos de próxima generación.\n",

"abstract": "In earlier work, we have developed and evaluated an alternative approach to the analysis of GWAS data, based on a statistic called the PPLD. More recently, motivated by a GWAS for genetic modifiers of the X-linked Mendelian disorder Duchenne Muscular Dystrophy (DMD), we adapted the PPLD for application to time-to-event (TE) phenotypes. Because DMD itself is relatively rare, this is a setting in which the very large sample sizes generally assembled for GWAS are simply not attainable. For this reason, statistical methods specially adapted for use in small data sets are required. Here we explore the behavior of the TE-PPLD via simulations, comparing the TE-PPLD with Cox Proportional Hazards analysis in the context of small to moderate sample sizes. Our results will help to inform our approach to the DMD study going forward, and they illustrate several respects in which the TE-PPLD, and by extension the original PPLD, offer advantages over regression-based approaches to GWAS in this context.",

"abstract": "In mammals, the biological activity of the stem/progenitor compartment sustains production of mature gametes through spermatogenesis. Spermatogonial stem cells and their progeny belong to the class of undifferentiated spermatogonia, a germ cell population found on the basal membrane of the seminiferous tubules. A large body of evidence has demonstrated that glial cell line-derived neurotrophic factor (GDNF), a Sertoli-derived factor, is essential for in vivo and in vitro stem cell self-renewal. However, the mechanisms underlying this activity are not completely understood. In this study, we show that GDNF induces dose-dependent directional migration of freshly selected undifferentiated spermatogonia, as well as germline stem cells in culture, using a Boyden chamber assay. GDNF-induced migration is dependent on the expression of the GDNF co-receptor GFRA1, as shown by migration assays performed on parental and GFRA1-transduced GC-1 spermatogonial cell lines. We found that the actin regulatory protein vasodilator-stimulated phosphoprotein (VASP) is specifically expressed in undifferentiated spermatogonia. VASP belongs to the ENA/VASP family of proteins implicated in actin-dependent processes, such as fibroblast migration, axon guidance, and cell adhesion. In intact seminiferous tubules and germline stem cell cultures, GDNF treatment up-regulates VASP in a dose-dependent fashion. These data identify a novel role for the niche-derived factor GDNF, and they suggest that GDNF may impinge on the stem/progenitor compartment, affecting the actin cytoskeleton and cell migration.",

Currently little transcriptomic and small RNAomic data are available to reveal the genes involve in the stress resistant in S. matsudana. Here, we report the RNA-seq analysis results of both transcriptome and small RNAome data using Illumina deep sequencing of shoot tips from two willow variants(Salix. matsudana and Salix matsudana Koidz. cultivar 'Tortuosa'). De novo gene assembly was used to generate the consensus transcriptome and small RNAome, which contained 106,403 unique transcripts with an average length of 944 bp and a total length of 100.45 MB, and 166 known miRNAs representing 35 miRNA families. Comparison of transcriptomes and small RNAomes combined with quantitative real-time PCR from the two Salix libraries revealed a total of 292 different expressed genes(DEGs) and 36 different expressed miRNAs (DEMs). Among the DEGs and DEMs, 196 genes and 24 miRNAs were up regulated, 96 genes and 12 miRNA were down regulated in S. matsudana. Functional analysis of DEGs and miRNA targets showed that many genes were involved in stress resistance in S. matsudana. Our global gene expression profiling presents a comprehensive view of the transcriptome and small RNAome which provide valuable information and sequence resources for uncovering the stress response genes in S. matsudana. Moreover the transcriptome and small RNAome data provide a basis for future study of genetic resistance in Salix.",

"description": "Objective The study aims to develop an artificial intelligence (AI) framework for automatic pressure injury (PI) staging directly from raw clinical images, without requiring manual lesion localisation. By integrating a two-stage deep learning approach—combining object detection and image classification—the proposed system seeks to improve diagnostic accuracy, reduce subjectivity and support consistent staging in real-world clinical workflows.Methods We conducted a retrospective study using 1807 PI images from China Medical University Hospital collected between 2020 and 2024. Lesions were annotated by five senior nurses with consensus. YOLOv9 was used for lesion detection, and DenseNet161 for staging. Performance metrics included accuracy, sensitivity, specificity, F1 score, area under the curve (AUC) and mean average precision (mAP)@0.5.Results The object detection model (YOLOv9) achieved an mAP@0.5 of 0.796. On the independent test set (n=365), the staging model demonstrated an overall accuracy of 0.775, sensitivity of 0.775, specificity of 0.955, precision of 0.779 and F1 score of 0.775.Discussion The proposed two-stage AI framework—using YOLOv9 for lesion localisation and DenseNet161 for staging—demonstrated performance comparable to or exceeding previously reported approaches, while offering improved clinical interpretability when applied to real-world clinical images. By separating detection and classification, the framework reduced background noise and improved the ability to distinguish visually similar PI stages. However, challenges remain in handling intra-wound heterogeneity, subtle early-stage boundaries and variability in image quality.Conclusions This two-stage AI system may assist clinical staff by providing standardised, reproducible PI staging from clinical images, with potential for integration into nursing workflows.",

"description": "Introduction Surgery and its resulting hospitalisation are associated with subsequent cognitive and functional decline. Interventions to reduce this decline have exhibited limited success. Prehabilitation is the process of enhancing capacity and reserve before an acute stressor to improve tolerance of the acute physiologic insult. Older adults requiring major surgery are an ideal population for prehabilitation. Prehabilitation exercise studies have mostly focused on physical training to improve physical outcomes after specific surgery types, and data on cognitive outcomes and in broader surgical populations are needed. Computerised cognitive training (CCT) has been shown to enhance memory, processing speed, attention and multitasking. Combining CCT with a physical exercise may be most effective in reducing cognitive and functional decline in older patients undergoing major surgery, but has yet to be evaluated.Methods and analysis The COgnitive and Physical Exercise to improve Outcomes after Surgery (COPE-iOS) study is a randomised, controlled, participant and assessor blinded clinical trial testing the hypothesis that a pragmatic programme combining CCT and physical exercise throughout the perioperative (ie, preoperative and postoperative) period will improve long-term cognitive and disability outcomes in older surgical patients at high risk for decline. The trial aims to randomise 250 patients who undergo major surgery for a treatment period of approximately 1 month prior to surgery and 3 months after surgery, with a follow-up period of 12 months after surgery. The primary outcome is global cognition at 3 months after surgery. Key secondary outcomes include global cognition at 12 months after surgery and disability in activities of daily living and depression at 3 and 12 months after surgery.Ethics and dissemination Trial protocol has been approved by Vanderbilt Human Research Protections Programme (#202496) and an independent Data Safety Monitoring Board. Results will be presented at scientific conferences and submitted for publication.Trial registration number ClinicalTrials.gov Registry NCT04889417.",

"description": "Introduction Adverse neurological complications, including postoperative delirium (POD) and stroke, remain one of the major risks after cardiac surgery. A lack of comprehensive knowledge about their causes and neuroprotective strategies has hindered the development of effective interventions to reduce these events. Personalised cerebral autoregulation (CA)-oriented blood pressure monitoring aims to identify blood pressure targets tailored to each individual patient, thereby reducing brain injury. The PRECISION study aims to assess whether perioperative duration and magnitude of mean arterial pressure (MAP) deviation from an individual’s CA limits are associated with adverse neurological complications.Methods and analysis This international, multicentre, prospective cohort study is conducted at two Swiss and one British hospital. Patients aged 65 years or older undergoing elective primary or re-operative coronary artery bypass graft and/or valvular and/or ascending aorta surgery requiring cardiopulmonary bypass are included. Preoperatively, the patient’s baseline of physical, cognitive and mental status is established. Intraoperatively, near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) are recorded in real-time to generate NIRS-derived and TCD-derived CA indices. The primary endpoint is POD, assessed daily on postoperative days 0 to 7 or up to discharge, whichever occurs earlier with the 3D-Confusion Assessment Method (3D-CAM) or CAM-Intensive Care Unit. Secondary endpoints include a composite neurological outcome of POD and overt stroke, postoperative neurocognitive disorders, major morbidity and mortality. Associations between neurologic outcomes, neurobiomarkers and genetic variation will be explored.A total of 500 participants is required to achieve 90% power to find a statistically significant effect of the area under the curve MAP<lower limit of CA (LLA) on the risk of POD at the 5% level. This includes adjustment for potential confounders and for the inability to determine the LLA.Ethics and dissemination Ethical approval has been obtained from all responsible ethics committees (Swiss lead ethics committee EKNZ 2022-01457 and Health Research Authority and Health and Care Research Wales, UK, REC 23/SW/0076). Results will be disseminated at national and international conferences and published in peer-reviewed journals.Trial registration number NCT05595954.",

"description": "Introduction High costs of screening and diagnostic tests remain a major barrier to timely tuberculosis (TB) identification in resource-limited settings. Evidence on the cost-effectiveness of scalable screening algorithms is limited. Start4All is a research project aimed at developing and evaluating algorithmic approaches to TB screening and diagnosis, with the goal of optimising technical and allocative efficiency when expanding diagnostic coverage to primary healthcare and community settings.Methods and analysis Five screening and diagnostic tests will be evaluated: a capillary blood-based assay (C-reactive protein (CRP)), sputum-based rapid molecular tests (PCR; individual and pooled Xpert MTB/RIF Ultra assay (Xpert Ultra, Cepheid®, California, USA)), a lateral-flow urine-based test for lipoarabinomannan (LF-LAM), and digital chest X-rays with artificial intelligence-based computer-aided detection (CXR-CAD). A microbiological reference standard of positive culture using the mycobacteria growth indicator tube will be used to confirm TB disease.We will compare the cost and effectiveness of concurrent and sequential positive serial combinations (screening algorithms) of CRP, CXR-CAD, LF-LAM, individual and pooled Xpert Ultra. Diagnostic performance will be estimated using sensitivity, specificity, predictive values and proportions of positive results, with Bayesian inference used to derive these estimates. The analysis will include adults (15 years and older) only and will be stratified by HIV status and level of care, including facility and community-based case finding. Effectiveness will be assessed based on the number of people with TB detected. Cost analysis will be conducted from the provider perspective, incorporating commodity and implementation costs. A decision tree model will be developed to assess the cost per number of persons with confirmed TB detected across all countries. Probabilistic sensitivity analysis will be conducted to account for uncertainty in model parameters, incorporating willingness-to-pay and willingness-to-accept thresholds.Ethics and dissemination WHO ethical review committee approval ERC.0003921. Data will be available on reasonable request to the principal investigator of the consortium.Trial registration number NCT05845112.",

"description": "Packaging does not only protect a product but also provides directions for using the product, as well as relevant information about its content and nutritional value. This study was undertaken to assess Granulated Cassava (Gari) sellers’ perception, profitability and determinants of packaging in Ashanti Region. The study area was purposively selected because of the active participation and contribution of marketing activities. A structured questionnaire was administered in the form of interview to obtain primary data from the respondents. Data was generated using binary and multinomial logit regression model and Garret ranking technique. The results showed that there is 0.11% difference in the gross margin of both ventures which is also statistically significant at 1%. Years of education, legal requirement, and durability of the packaging material and cost of packaging material were the significant factors that influence sellers’ choice of packaging. Lack of technical know-how, cost of capital equipment and lack of knowledge on packaging equipment and/or material were the most limiting constraints affecting Gari packaging. The study recommends that investors should invest in the Gari packaging business since it has a relatively higher rate of returns as compared to the unpackaged one.",

"description": "This study examines female youth participation in agricultural livelihood generating activities for self-care in Gwagwalada Area Council, Abuja. The objectives were to: examine the extent of female youth participation in agricultural livelihood generating activities and the income generated, determine the levels of female youth self-care responsibilities and perceived contribution of participation in agricultural livelihood activities on their wellbeing, determine factors influencing female youth participation in agricultural livelihood activities in the study area. A multistage sampling procedure was used to select 133 female youths from 13 registered youth associations. Structured questionnaire was used to collect data while descriptive statistics and Logit regression model were used to analyze the data. The results showed that 30.1% of the respondents were engaged in crop production and generated an average income of ₦420,093.02 while only 3.0% were engaged in crop produce processing and generated ₦29,250.74. Also, almost half (47.4) of them spent money to take care of themselves of between 3-4 self-care responsibilities and about 41.5 spent an average of 130,078.95 on food per day. It also showed The logit regression results indicated that factors influencing female youth participation in agricultural livelihood generating activities include age, educational status, household size, income, occupation, and distance. While the study indicates that a significant portion of female youths is engaged in crop and poultry production, their overall participation in agricultural activities is limited. The study provides critical insights into the potential of agriculture as a viable solution to youth unemployment and is an instrument of female vulnerability reduction in Nigeria. The study recommends implementing policies to improve land access for female youths, including land reform initiatives that prioritize youth ownership and leasing options. Additionally, it suggests exploring strategies to reduce production costs through input subsidies, partnerships with agricultural suppliers, and community-based resource-sharing initiatives.",

"description": "In our survey-based research, assessed the opinions of 39 small and medium-sized enterprise (SME) leaders in Hajdú-Bihar County on digitalization, how they evaluate their employees' digital skills, what digital best practices they apply, and how familiar they are with current trends in digital best practices. In the literature review, we touch on the concepts and significance of digitalization and digital transformation, the characteristics and types of best practices, benchmarking as a tool for identifying them, and the steps involved in their implementation. We introduced five currently popular digital best practices: optical character recognition, homomorphic encryption, robotic process automation, intelligent process automation, and blockchain technology. The advantages and impact of these practices on corporate efficiency are highlighted. Based on the results, we reached the following conclusions:\nThe findings show that most Hungarian companies view digitalization as an opportunity, but there are deficiencies in strategic planning and commitment. Although leaders theoretically support technological progress, 93% of companies do not have a developed digital strategy, and leaders also rate employee engagement as low. The resources allocated for digitalization investments are also low, with most companies spending only between 0-10 million HUF. The application of artificial intelligence (AI) technologies is still in its early stages, though there are positive examples. Dissatisfaction is evident regarding employees' digital competencies, particularly in problem-solving and data security. The lack of knowledge of modern digital technologies also hinders innovation. Companies' digital maturity is low, with most having only taken initial steps in this area. Often, the perceived digital intensity of the industry does not reflect reality, which can hinder development.",

"description": "Women often lack access to productive resources such as land and capital in most developing countries. This forces them to take part in off-farm activities to augment their little farm income. This study investigated factors that affect the involvement of women farmers in different types of off-farm entrepreneurial livelihood activities in rural Bauchi state, Nigeria. A purposive sampling method was used in selecting three local government areas in the western agricultural zone of the state and a random sampling method was used in selecting ten wards. 5% registered women farmers in each selected ward, making 134 respondents. Semi-structured questionnaires were administered to women farmers in 2017. The results revealed that food processing, farm product sales, trading and tailoring are the major off-farm livelihood activities engaged in by rural female farmers. Logit regression results revealed, as expected, that different factors affect their involvement in various types of off-farm activities. Food processing and tailoring required relatively high start-up capital and access to electricity as an investment and the use of machines was needed. Thus, access to credit or remittances and to electricity increases the probability of being involved in these activities. The requirements of trading being lower and access to market increases the probability of being involved. Provision of extension services, rural credit facilitation programmes, rural electrification, road and market structure development are instruments that are appropriate to support women farmers' involvement in off-farm activities.",

### Journals By Publisher
DOAJ journals by publisher name — the bibjson.publisher.name: binding over search/journals. The name is phrase-matched, so it must be spelled as DOAJ has it.
- **Method:** `GET`
- **Endpoint:** `https://api.zpi.web.id/v1/research:doaj/journals-by-publisher`
- **Cache TTL:** 300s
**Parameters:**
| Name | Type | Location | Required | Description |
|------|------|----------|----------|-------------|
| `publisher` | string | query | yes | Publisher name as DOAJ records it, matched as a phrase |
| `page` | number | query | no | Page number. Default 1 |
| `limit` | number | query | no | Items per page. Default 10, max 100 |
**cURL:**
```bash
curl "https://api.zpi.web.id/v1/research:doaj/journals-by-publisher?publisher=Elsevier&page=1&limit=10" \
-H "x-api-key: YOUR_API_KEY"
```
**JavaScript / TypeScript:**
```javascript
const res = await fetch("https://api.zpi.web.id/v1/research:doaj/journals-by-publisher?publisher=Elsevier&page=1&limit=10", {
headers: { "x-api-key": process.env.ZAPI_KEY }
});
const data = await res.json();
```
**Python:**
```python
import requests
r = requests.get("https://api.zpi.web.id/v1/research:doaj/journals-by-publisher?publisher=Elsevier&page=1&limit=10",

A less well-known complication is spontaneous pathologic splenic rupture, which is still under-reported and has never been reported in Israel. In this paper, we report a 23 years old healthy young man presenting in the emergency department, two weeks after coming back from Sierra Leone, with intermittent fever, mild tachycardia and mild left upper quadrant abdominal pain. The patient was diagnosed with Plasmodium falciparum infection and developed rapidly after hospital admission spleen rupture. He was managed conservatively at first but ultimately underwent splenectomy after being hemodynamically unstable. In the recovery period, the patient developed acute respiratory distress syndrome and was reintubated. A high level of suspicion is recommended in every malaria patient presenting with left upper quadrant abdominal pain, even if minimal. Ultrasonography availability in the internal medicine department may be a critical diagnostic tool, especially in non-endemic areas.",

"abstract": "ABSTRACT The malaria parasite, Plasmodium falciparum, was introduced into Hispaniola and other regions of the Americas through the slave trade spanning the 16th through the 19th centuries. During this period, more than 12 million Africans were brought across the Atlantic to the Caribbean and other regions of the Americas. Since malaria is holoendemic in West Africa, a substantial percentage of these individuals carried the parasite. St. Domingue on Hispaniola, now modern-day Haiti, was a major port of disembarkation, and malaria is still actively transmitted there. We undertook a detailed study of the phylogenetics of the Haitian parasites and those from Colombia and Peru utilizing whole-genome sequencing. Principal-component and phylogenetic analyses, based upon single nucleotide polymorphisms (SNPs) in protein coding regions, indicate that, despite the potential for millions of introductions from Africa, the Haitian parasites share an ancestral relationship within a well-supported monophyletic clade with parasites from South America, while belonging to a distinct lineage. This result, in stark contrast to the historical record of parasite introductions, is best explained by a severe population bottleneck experienced by the parasites introduced into the Americas. Here, evidence is presented for targeted selection of rare African alleles in genes which are expressed in the mosquito stages of the parasite’s life cycle. These genetic markers support the hypothesis that the severe population bottleneck was caused by the required adaptation of the parasite to transmission by new definitive hosts among the Anopheles (Nyssorhynchus) spp. found in the Caribbean and South America. IMPORTANCE Historical data suggest that millions of P. falciparum parasite lineages were introduced into the Americas during the trans-Atlantic slave trade, which would suggest a paraphyletic origin of the extant isolates in the Western Hemisphere. Our analyses of whole-genome variants show that the American parasites belong to a well-supported monophyletic clade. We hypothesize that the required adaptation to American vectors created a severe bottleneck, reducing the effective introduction to a few lineages. In support of this hypothesis, we discovered genes expressed in the mosquito stages of the life cycle that have alleles with multiple, high-frequency or fixed, nonsynonymous mutations in the American populations which are rarely found in African isolates. These alleles appear to be in gene products critical for transmission through the anopheline vector. Thus, these results may inform efforts to develop novel transmission-blocking vaccines by identifying parasite proteins functionally interacting with the vector that are important for successful transmission. Further, to the best of our knowledge, these are the first whole-genome data available from Haitian P. falciparum isolates. Defining the genome of these parasites provides genetic markers useful for mapping parasite populations and monitoring parasite movements/introductions.",

"abstract": "Introduction: This study was conducted to compare and evaluate the knowledge as well as the practice of community health volunteers, Accredited social health activists (ASHAs) in low and high malaria-endemic regions of Tripura, Northeast India. Materials and Methods: In this descriptive cross-sectional study, all ASHAs working in the randomly selected two blocks of each low and high malaria-endemic areas were included in the study. While ASHAs with less than 1-year experience were excluded from the study. The ASHAs were interviewed and information was gathered on knowledge and practice against malaria management. Chi-square test was used to identify differences in responses among the ASHAs. Results: Significant differences in knowledge of mixed malarial infection (P < 0.001) and early symptoms of malaria (P = 0.005) were observed when responses of high malaria-endemic ASHAs (HMEA) were compared to low endemic ASHAs (LMEA). With respect to malaria testing skills, 83.16% HMEA affirmed that they could perform Rapid diagnostic (RD) kit tests as opposed to 57.24% LMEA, (P < 0.001). Disturbingly only two HMEA could correctly describe the duration for Pf and Pv treatment. Conclusion: The study identifies major lacunae in the balance of knowledge and practices of ASHAs in both study areas of Tripura. Therefore,for a successful projected malaria elimination program, community-level ASHA volunteers need to have accurate malaria knowledge and management approaches irrespective of the endemicity. This study will help to understand the operational constraints and plan educational training for ASHA volunteers in malaria-endemic regions.",
