Authors: Gyedu Samuel , Tang Heng
Published: February 2024

In order to reach the carbon neutrality (CAN) target, this current study examined the roles of research and development (R&D), patent (PAT), economic growth (ECG), renewable energy consumption (REC), renewable internal freshwater (RIF) and carbon taxes (CAT) in achieving CAN from BRICS perspective. We employed panel data of BRICS countries from 2000 to 2020 with second-generational econometric estimators (AMG and CCEMG). We discovered that R&D, RIF and CAT promote CAN by mitigating carbon emissions (CO2) and methane emissions (CH4). Our findings indicated REC contributes massively in achieving CAN. ECG was found to initially delays CAN objective. We detected Environmental Kuznets Curve (EKC) in BRICS. URB and IND also had controlling influence by prolonging CAN agenda. The authors found a feedback mechanism from ECG, REC, RIF, CAT to CO2, and from R&D, REC, RIF, CAT and URB to CH4 in BRICS, indicating that R&D, ECG, REC, RIF, and CAT granger cause to CAN and vice versa. Finally, based on the country-wise details analysis of the variables, China recorded the highest CO2, CH4, ECG and PAT, India had the highest R&D, Brazil the highest REC, and Russia the highest RIF and CAT.

Background
Physical examination involves clinical skills where therapists or trainees use their hands to assess tissues or joints for the presence or absences of abnormalities. The traditional “See one, do one, teach one” approach to teach these techniques has been shown to be inadequate. Therefore, digital applications such as virtual reality (VR) have been recommended to assist in teaching physical examination skills of health care students. The aims of this systematic review are to 1) Summarise the level of evidence for the current usage of VR with haptic feedback in health education for improving physical assessment skills among students; and (2) To synthesise the literature on facilitators and barriers for implementing VR with haptic feedback as a health education tool in improving physical assessment skills of students.
Methods
The following electronic databases were searched: PubMed, AMED, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database (PEDro), and SCOPUS. Two independent reviewers reviewed the articles retrieved from the databases to assess for eligibility. Studies of any methodology (quantitative, qualitative and mixed methods) that investigated the use of VR were included in the review. Primary outcomes included any quantifiable outcome and/or qualitative outcome/feedback. Narrative synthesis was used to synthesise data from the included studies.
Results
A total of 9 studies were included in the final review. Overall, our review found ‘very low’ evidence that VR with haptic feedback may improve palpation of stiffness, palpation speed and palpation accuracy. A ‘conditional recommendation of the intervention’ depending on the context, access and resources required to set-up the required technology.
Discussion
Our review indicates that VR with haptic feedback may enhance palpatory skills of health care students. However, the applicability of evidence may be confined to palpatory skills of health students rather than physical examination skills of health students. Hence, more research is required to identify whether VR with haptic feedback does improve physical examination skill of students.

Relapse is a major cause of death after allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia (AML). Treatment options for patients who relapse are very limited. Programmed death (PD)-1 blockade has shown therapeutic activity in selected hematologic malignancies, but would trigger severe graft-versus-host disease (GvHD), which is a major obstacle to its success. Herein, we reported the results of sequential PD-1 blockade therapy in patients with relapsed AML after umbilical cord blood transplantation (UCBT). We undertook positron emission tomography–computed tomography to assess the efficacy of sequential PD-1 blockade in patients with AML who relapsed after UCBT. Adequate biopsy analyses revealed an increased number of pro-inflammatory macrophages and increased interleukin-1β (IL-1β) expression in the colon and skin of a patient with severe acute (a)GvHD post-anti-PD-1 therapy. Importantly, we demonstrated low expression of NKG2A in the skin and blood of a patient with aGvHD after anti-PD-1 therapy. Our findings imply that dynamic detection of NKG2A expression in blood or IL-1β expression in tissue could indicate GvHD, and contribute to guiding treatment decisions for sequential PD-1 blockade therapy.

Published: February 2024

Background The relative age effect (RAE) has been a hot topic in the field of sport research, and although the phenomenon has been found in most sports in China, there is currently no literature on the RAE phenomenon in Chinese basketball, which has implications for explaining some of the phenomena in that sport. A large body of research suggests that RAE contributes significantly to the phenomena of brain drain and inequality in sport participation. The purpose of this study was to analyses whether RAE exists in Chinese youth men's basketball and whether RAE has an impact on the performance of athletes and teams, thus supporting the subsequent proposal of measures to balance the age effect.Methods This study analyzed the date of birth and performance rankings of all male athletes (n = 3926) who participated in the Chinese Youth Basketball Championships (U14, U15, and U17) from 2021–2023. The study divided the month of birth into quarters and semesters. Differences between actual observed and theoretical birth date distributions were statistically analyzed using the chi-square test, and subsequent calculations were made using the dominance ratio test.Results It was found that RAE was present in all three groups of Chinese youth male basketball players (p < 001). The percentages of athletes born in the first half of the year were 61.2% (U14), 59.9% (U15), and 59.0% (U17), and the percentages of athletes born in the first quarter were 38.6% (U14), 35.8% (U15), and 34.8% (U17).Conclusions As a result of RAE, U15 athletes born closer to the beginning of the year are likely to achieve better results, whereas athletes born closer to the end of the year are less likely to achieve athletic excellence.

Published: February 2024

Rheumatoid arthritis-interstitial lung disease (RA-ILD), associated with Rheumatoid Arthritis (RA), typically manifests as usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP). However, the pathogenic mechanisms underlying RA and its related ILD are not fully understood. The progression of single-cell sequencing technology has enhanced our comprehension of the inflammatory environment, offering potential insights into inflammation-related cells. In this study, we conducted single-cell sequencing and cell communication analysis on peripheral blood mononuclear cells (PBMCs) from patients with RA, RA + UIP, and RA + NSIP. Our results revealed that blood cells from patients were annotated as T cells, NK cells, neutrophils, red blood cells, B cells, monocytes, macrophages, dendritic cells, platelets, and hematopoietic stem cells, indicating the accumulation of T cells in the inflammatory environment. Temporal analysis suggested a differentiation trend in T cells: CD4 + T cells, regulatory T cells, CD69 + T cells, and CD8 + T cells. Subgroup enrichment analysis of T cells identified significantly differentially expressed genes (DEGs) enriched in pathways such as rheumatoid arthritis, IL-17 signaling, Th1 and Th2 cell differentiation, Th17 cell differentiation, and TNF signaling. Further investigation revealed the pro-inflammatory characteristics of this subgroup, and cell communication results indicated a pivotal role of T cells. In summary, our comprehensive analysis identified T cells as crucial mediators in RA-ILD and unveiled potential pathways, including interactions among HLA, MIF, CLEC2C ligands, and CD8A, CD8B, CD74 receptors. These findings provided potential biomarkers for effective treatment targets and intervention strategies, deepening our understanding of T cell participation in the immune pathogenesis of RA-ILD.

Published: February 2024

Background
Colorectal ESD, an advanced minimally invasive treatment, presents technical challenges, with globally varying training methods. We analyzed the learning curve of ESD training, emphasizing preoperative strategies, notably gravity traction, to guide ESD instructors and trainee programs.
Method
This retrospective study included 881 cases guided by an experienced supervisor. Six trainees received “strategy-focused” instruction. To evaluate the number of ESD experiences in steps, the following phases were classified based on ESD experiences of each trainees: Phase 0 (0–50 ESD), Phase 1 (51–100 ESD), Phase 2 (101–150 ESD), and Phase 3 (151–200 ESD). Lesion background, outcomes, and safety were compared across phases. Factors contributing to technical difficulty in early (Phase 0 and 1) and late phases (Phase 2 and 3) were identified, along with the utility of traction ESD with device assistance.
Result
Treatment outcomes were favorable, with 99.8% and 94.7% en bloc resection and curative resection rates, respectively. Approximately 90% self-completion rate could be achieved after experiencing about 50 cases (92.7% in Phase 1), signifying proficiency growth despite increased case difficulty. In early phases, factors such as right-sided colon, LST-NG morphology, and mild and severe fibrosis pose challenges. In late phases, mild and severe fibrosis remained significant. Traction-assisted ESD, utilized in 3% of cases, comprised planned (1.1%) and rescue (1.9%) methods. Planned traction aided specific lesions, while rescue traction was common in the right colon.
Conclusion
"Strategy-focused" ESD training consistently yields successful outcomes, effectively adapting to varying difficulty factors in different proficient stages.
A novel strategy to facilitate uniform epithelial cell maturation using liquid–liquid interfaces
Authors: Sonoi Rie , Kamihira Masamichi
Published: February 2024

Epithelial tissue forms and maintains a critical barrier function in the body. A novel culture design aimed at promoting uniform maturation of epithelial cells using liquid materials is described. Culturing Madin–Darby canine kidney (MDCK) cells at the liquid–liquid interface yielded reduced migration and stimulated active cell growth. Similar to solid–liquid interfaces, cells cultured on a fibronectin-coated liquid–liquid interface exhibited active migration and growth, ultimately reaching a confluent state. These cells exhibited reduced stress fiber formation and adopted a cobblestone-like shape, which led to their even distribution in the culture vessel. To inhibit stress fiber formation and apoptosis, the exposure of cells on liquid–liquid interfaces to Y27632, a specific inhibitor of the Rho-associated protein kinase (ROCK), facilitated tight junction formation (frequency of ZO-2-positive cells, FZ = 0.73). In Y27632-exposed cells on the liquid–liquid interface, the value obtained by subtracting the standard deviation of the ratio of nucleus densities in each region that compartmentalized a culture vessel from 1, denoted as HLN, was 0.93 ± 0.01, indicated even cell distribution in the culture vessel at t = 72 h. The behavior of epithelial cells on liquid–liquid interfaces contributes to the promotion of their uniform maturation.

Authors: Andrade Luís Jesuino de Oliveira , de Oliveira Gabriela Correia Matos , França Caroline Santos , Bittencourt Alcina Maria Vinhaes , Nascimento Guilherme Peixoto , Silva Catharina Peixoto , de Oliveira Luís Matos
Published: February 2024

Background: Ocular surface disorders (OSD) are highly prevalent, affecting millions globally. While conventional treatments offer some level of success, they often fall short in addressing challenging refractory cases. This unmet need has spurred the investigation of novel therapeutic approaches, including the exploration of topical insulin as a potential alternative.
Objective: This systematic review and meta-analysis evaluated the safety and efficacy of topical insulin for OSD management.
Methods: We conducted a comprehensive search across major databases (PubMed, Scopus, Embase, and Cochrane Library) for studies investigating the use of topical insulin for ocular conditions. Studies were rigorously selected based on pre-defined inclusion/exclusion criteria and assessed for methodological quality using established tools. We extracted and analyzed data pertaining to safety, efficacy, and relevant outcomes for meta-analysis, including healing time.
Results: Ten studies (diverse designs: 1 case-control, 3 randomized prospective, 3 retrospective, and 3 double-blind) met the inclusion criteria. These studies explored a range of OSD, including neurotrophic corneal ulcers, persistent epithelial defects, recurrent epithelial erosions, dry eye disease, and postoperative corneal wound healing in diabetic patients. The findings suggest encouraging outcomes for topical insulin across these indications, demonstrating its potential to OSD. A meta-analysis comparing healing times between topical insulin and placebo revealed a statistically significant advantage for the insulin group (Q = 26.81, df = 3, P = 0.000, I² = 96%).
Conclusion: This comprehensive review and meta-analysis provide promising evidence for the therapeutic potential of topical insulin in diverse OSD. While methodological limitations exist, particularly in non-randomized studies, the current body of evidence suggests that topical insulin may offer a safe and effective treatment option for patients with refractory OSD.

Published: February 2024

An ethnobotanical survey of medicinal and other economically important flora used by native people in Bahawalnagar was carried out from April 2020 to December 2020. To compile and document medicinally and economically important plants in accordance with traditional practices in the area, the aim of this study was to conduct ethnobotanical investigations in the area. A total of 54 informants, including 9 hakims (herbal doctors) and 3 pansars (medicinal plant traders), were randomly selected from the study sites. Ethnobotanical data were collected using semistructured questionnaires, field observations, interviews and group discussions. During the course of the study, 58 plant species belonging to 32 families were collected in the study area. Cucurbitaceae has 6 plant species, and Fabaceae and Poaceae have 4 plant species. The most frequently used plant parts were the leaves (39%), followed by fruits (43%). The most widely treated diseases were abdominal problems followed by general body pain. In the study area, agricultural expansion, firewood collection, timber production, and construction pose major threats to plants in general and medicinal plants in particular. The cultivation of medicinal plants is not common in the region. The management and conservation of medicinal plants has been made possible in part by indigenous practices, diverse cultural customs, and seasonally restricted plant collection. As a result, people should be given the opportunity to grow medicinal plants at home in their gardens. The local people should be encouraged to be involved in the sustainable utilization and management of plant resources, as well as creating awareness by educating them on how to do so.
Glass scenographies : notes on spaces of one's own
Authors: Gellai Szilvia
Published: February 2024

In the first half of the 20th century, when architecture and literature dreamed of transparency, glass was the material these dreams were made of. However, the historiography of both fields usually focuses on a few canonical works by male authors to tell the story of this shared fascination. Departing from this imbalance, this essay takes the opportunity to explore the glass culture of modernity through the lens of female projects whose stories often take place simultaneously on different continents. While the former silent film actor Evelyn Word Leigh builds a glass house for herself in Nyack, New York, artists and writers based in Europe – like Claude Cahun, Anaïs Nin, and Hilda 'H.D.' Doolittle – flesh out imaginary glass domes as construction sites of artistic subjectivities. Whether homes or domes, these creative women used glass environments to question and renegotiate their assigned places in Western societies, challenging the boundaries of female agency.

Assessment of the Impact of Financial Intermediation on Gross Domestic Product in Nigeria from 1996 to 2022
Authors: Isaac AGBOLA Abolade , KELIKUME Ikechukwu , AGUNBIADE Olabode
Published: February 2024

This paper assesses financial intermediation in Nigeria and how it has impacted economic growth. The study sourced time series data between 1996 and 2022 from the Central Bank of Nigeria and utilized econometric techniques using Ordinary least square regression, Error correction model, and Pairwise Causality to assess the impact of the financial intermediation institutions on the growth of the nation's Gross Domestic Product. The paper focused on banks, capital markets, and the insurance industry being significant institutions in the financial system. The GDP is the dependent variable, while Credit to the Private Sector as a percentage of GDP (CPS/GDP) and Total Savings as a percentage of GDP (TS/GDP) were used as proxies for assessing banks' contributions to economic growth. Stock market capitalization was used as a proxy for the contribution of the capital market to economic growth, and Insurance industry assets were used as a proxy for the insurance industry's contribution to economic growth. The study revealed no co-integration and long-term relationship between economic growth and the financial intermediation variables. There was, however, a unidirectional causal relationship between economic growth and the banks and the capital markets. There was no causality between economic growth and insurance. We recommend that policymakers undertake periodic reforms to deepen the capacity of the institutions to support de-risking and funding small and medium enterprises and the agricultural value chain, which are vital channels for diversifying the economy. The regulatory authorities are pivotal in upscaling the institutions' contribution to economic development.

Analysis of scaling relationships for flood parameters and peak discharge estimation in a tropical region
Authors: Mazivanhanga Charles , Grabowski Robert C. , Pérez-Sánchez Eunice , Carballo-Cruz Victor R.
Published: February 2024

Relationships between peak discharges and catchment size (e.g., flood scaling) in a catchment have the potential to support new river flood forecasting approaches but have not been tested in tropical regions. This study determined flood scaling relationships between peak discharge and nested drainage areas in the La Sierra catchment (Mexico). A statistical power law equation was applied to selected rainfall–runoff events that occurred between 2012 and 2015. Variations in flood scaling parameters were determined in relation to catchment descriptors and processes for peak downstream discharge estimation. Similar to studies in humid temperate regions, the results reveal the existence of log-linear relationships between the intercept (α) and exponent (θ) parameter values and the log–log power–law relationships between (α) and the peak discharge observed from the smallest headwater catchments. The flood parameter values obtained were then factored into the scaling equation (QP = αAθ) and successfully predicted downstream flood peaks, especially highly recurrent flood events. The findings contribute to a better understanding of the nature of flood wave generation and support the development of new flood forecasting approaches in unregulated catchments suitable for non-stationarity in hydrological processes with climate change.
Recent Developments in Nanotechnology and Immunotherapy for the Diagnosis and Treatment of Pancreatic Cancer
Authors: Sindhi Komal , Kanugo Abhishek
Published: February 2024

Pancreatic cancer kills millions of people worldwide each year and is one of the most
prevalent causes of mortality that requires prompt therapy. A large number of people suffering
from pancreatic cancer are detected at an advanced stage, with incurable and drug-resistant tumor,
hence the overall survival rate of pancreatic cancer is less. The advance phase of this cancer
is generated because of expression of the cancer-causing gene, inactivation of the tumorsuppressing
gene, and deregulation of molecules in different cellular signalling pathways. The
prompt diagnosis through the biomarkers significantly evades the progress and accelerates the
survival rates. The overexpression of Mesothelin, Urokinase plasminogen activator, IGFR, Epidermal
growth factor receptor, Plectin-1, Mucin-1 and Zinc transporter 4 were recognized in the
diagnosis of pancreatic cancer. Nanotechnology has led to the development of nanocarriersbased
formulations (lipid, polymer, inorganic, carbon based and advanced nanocarriers) which
overcome the hurdles of conventional therapy, chemotherapy and radiotherapy which causes
toxicity to adjacent healthy tissues. The biocompatibility, toxicity and large-scale manufacturing
are the hurdles associated with the nanocarriers-based approaches. Currently, Immunotherapybased
techniques emerged as an efficient therapeutic alternative for the prevention of cancer.
Immunological checkpoint targeting techniques have demonstrated significant efficacy in human
cancers. Recent advancements in checkpoint inhibitors, adoptive T cell therapies, and cancer
vaccines have shown potential in overcoming the immune evasion mechanisms of pancreatic
cancer cells. Combining these immunotherapeutic approaches with nanocarriers holds great
promise in enhancing the antitumor response and improving patient survival.

A Systematic Review about Building Characteristics as Dampness-Related Indicators
Authors: Sousa Joana
Published: February 2024

The consistent associations between dampness and health-related problems, such as allergies and asthma symptoms, explain the growing scientific interest in assessing housing characteristics. Due to a growing interest in the built environment, the present study performed a systematic review to investigate the prevalence of dampness related to specific building characteristics. The built environment is gaining significance in population well-being due to the substantial time spent indoors. This aspect is especially notable for specific demographics such as children and the elderly. This research is based on the PRISMA methodology and was conducted through scientific papers research published in independent peer-reviewed journals. This study’s key conclusions indicate a strong link between home characteristics and dampness-related risk predictors, such as the age of the building, the building materials, the type of ventilation systems, and other building characteristics. Maintenance and occupants’ behaviors through good ventilation practices, such as opening windows, were found to be the main remediation strategies. This research novelty involves the identification of home characteristics and dampness-related risk predictors common to a broad spectrum of studies, which makes it possible to identify measures to overcome these bottlenecks. From the constructive perspective, some characteristics, such as the age of the building, are not possible to modify; however, nowadays, technology and knowledge expertise can be used to minor building characteristics associated with health-related problems.

Từ kết quả thu được, bao bì PA được đề xuất dùng để bảo quản cây Xáo tam phân tươi cho quá trình sử dụng và thực hiện các nghiên cứu tiếp theo.
The Combination of Chinese and Western Sculpture Art and the Future Direction
Authors: Fuxin Wang
Published: February 2024

Sculpture art is the physical form of human emotion overflow. Sculpture is an important part of Chinese and Western culture. Whether ancient or modern, the creation of sculpture reflects the cultural spirit of the times. Due to the different cultural backgrounds, the themes of Chinese and Western sculpture art show great differences. The different cultures of China and the West determine that there are great differences between Chinese and Western sculpture art. With the development of economic globalisation, the collision and fusion of Chinese and Western cultures have prompted Chinese contemporary sculpture to present a combination of traditional and Western cultures. The performance of traditional and western culture in modern sculpture is analysed, and an effective way of combining Chinese and western culture is proposed from three aspects: theory and practice, connotation and function, and realism and realism. Sculpture art, as one of the important forms of artistic expression, is able to show the great differences between Chinese and Western cultures. The development of contemporary sculpture art, to recognize the significance of cultural integration and development, and to seek ways to effectively combine traditional Chinese culture with Western culture, so as to better promote the development of modern sculpture art.

El cultivo de la palma datilera en México se ha incrementado durante los últimos años, convirtiéndose en el tercer mayor productor de la variedad Medjool a nivel mundial. Sin embargo, los pequeños productores se enfrentan a varios retos en la recolección, clasificación y el empaque de este fruto, debido a que son procesos que se realizan principalmente de manera manual. El principal problema se presenta en la clasificación, donde se busca una correcta selección de la fruta a través de la identificación de diversos parámetros de calidad, como el estado de madurez. Una inapropiada selección del fruto, puede ocasionar muchas desventajas para el agricultor en su comercialización, siendo un sistema de visión artificial una posible alternativa de solución. Para poder procesar un alto volumen de información, fue necesario apoyarse en la infraestructura Huawei, en este caso se utilizó la arquitectura DaVinci la cual es diseñada exclusivamente para cómputo de inteligencia artificial (AI). Las principales contribuciones del proyecto fueron el desarrollo de aplicaciones de AI para apoyar a los pequeños productores de dátil en sus actividades de selección y clasificación. Así como, la generación de recurso humano especializado en el área de inteligencia artificial.

Su misión es contribuir a generar empleo y recursos para los invidentes y discapacitados. Para ello explota en exclusiva una modalidad de lotería, “el cupón”, y un elemento clave es el agente vendedor. En el presente trabajo se analizan pormenorizadamente sus caracteres y su organización. Se trata de un colectivo de trabajadores por cuenta ajena que configuran un entramado (red de ventas), con determinadas condiciones laborales que, sin duda, favorecen una integración real y efectiva de los invidentes en la sociedad.
La inspección del trabajo en Nicaragua: sus próximos retos
Authors: Ortega Castillo Bertha Xiomara
Published: February 2024

Si bien Nicaragua cuenta con un Reglamento de Inspectores desde 1945, la inspección del trabajo no ha cumplido con el papel que le corresponde por varias razones. Una de ellas es la falta de recursos, pero la de más peso es la política, por privilegiar al sector empresarial so pretexto de aumentar los empleos y atraer la inversión extranjera. El momento actual no puede ser más oportuno para imprimirle a la inspección del trabajo la dinámica para la que fue creada. El país cuenta con nuevas autoridades que tienen la intención de impulsar el trabajo decente con una Ley de Higiene y Seguridad del Trabajo, y con un proyecto de Ley General de Inspección del Trabajo. El reto está planteado, corresponde a las autoridades del nuevo gobierno hacerlo realidad.
