Authors: Li Bo , He Ying , Zhou Xielin 
Published: June 2024

Abstract

Objective: To explore the interaction mechanism between interpersonal trust, family capital, and physical activity behavior among college students using a cross-lagged study design, providing a theoretical basis for the healthy development of their physical and mental well-being.
Methods: A longitudinal follow-up survey was conducted among 412 college students in Sichuan Province, using the Interpersonal Trust Scale, Physical Activity Rating Scale, and Family Capital Scale, in two phases over eight weeks from early March (T1) to early May (T2) 2024.
Results: (1) The autoregressive path coefficients for interpersonal trust, family capital, and physical activity behavior were 0.51, 0.41, and 0.66, respectively, indicating good stability (p<0.001). (2) Interpersonal trust at T1 positively predicted family capital at T2 (β=0.28, p<0.001), and family capital at T1 also positively predicted interpersonal trust at T2 (β=0.23, p<0.001), indicating a mutual influence between family capital and interpersonal trust. (3) Family capital at T1 did not predict physical activity behavior at T2 (p>0.05), but physical activity behavior at T1 positively predicted family capital at T2 (β=0.20, p<0.001), indicating that physical activity behavior is a causal variable for family capital. (4) Interpersonal trust at T1 positively predicted physical activity behavior at T2 (β=0.16, p<0.001), while physical activity behavior at T1 did not predict interpersonal trust at T2 (p>0.05), suggesting that interpersonal trust is a causal variable for physical activity behavior. (5) Family capital mediated the relationship between interpersonal trust and physical activity behavior (α=0.046), with a confidence interval of [0.014,0.097].
Conclusion: There were no gender differences in the relationship between interpersonal trust, family capital, and physical activity behavior among college students. There was a longitudinal relationship between interpersonal trust, family capital, and physical activity behavior, where family capital and interpersonal trust mutually influence each other. Physical activity behavior was a positive causal variable for family capital, while interpersonal trust was a positive causal variable for physical activity behavior. Additionally, family capital mediated the relationship between interpersonal trust and physical activity behavior.

Abstract

The red alga Betaphycus gelatinus showed a monthly little variation in carrageenan yields, 3,6 anhydro galactose and sulfate contents for the native carrageenans (68.2 – 73.1%, 23.1-24.8% and 19.5 – 20.3%, respectively) and for alkali modified carrageenans (23.7 – 31.5%, 41.6 – 43.9% and 8.6 – 8.7%, respectively). The gelling, melting temperatures and gel strength of alkali modified carrageenans from April to June showed no change, with the recorded values of 40.8 o C, 74.5 o C and 310 g cm-2 , respectively. The molecular weight of the native carrageenan was primarily distributed at 876 kDa, with a small fraction at 1.2 kDa. 1 H and 13 C NMR spectra proved that the carrageenan is composed of a hybrid of beta carrageenan and kappa carrageenan. Calculated from the peak areas of the α-anomeric proton signals in 1 H NMR and the signal intensities of the anomeric carbons in 13 C NMR spectra indicated that the native carrageenan showed no much difference in components of beta carrageenan (51.8%) and kappa carrageenan (48.2%), but after alkali modified carrageenan, the beta carrageenan component increased significantly (68.6%) compared to the kappa carrageenan component (31.4%). These results will contribute more information of hybrid carrageenan from the red alga B. gelatinus in Vietnam.
Spectroscopic Insights into BSA-Mediated Deaggregation of m-THPC

Published: June 2024

Abstract

Meta-tetra(hydroxyphenyl)chlorin (m-THPC) is among the most potent photosensitizers, known for its high singlet oxygen generation efficiency. However, its clinical effectiveness in photodynamic therapy (PDT) is compromised by its propensity to aggregate in aqueous solutions, adversely affecting its photophysical properties and therapeutic potential. A series of spectroscopic techniques, including UV-Vis absorption, fluorescence spectroscopy, and laser flash photolysis, revealed that m-THPC exhibits significant aggregation, particularly in MeOH-PBS mixtures with MeOH content below 30%. This aggregation adversely affects its photophysical properties leading to reduced fluorescence quantum yield and most importantly reducing its singlet oxygen quantum yield. This study introduces the use of bovine serum albumin (BSA) to counteract the aggregation of m-THPC, aiming to enhance its solubility, stability, and efficacy in physiological settings. Through advanced spectroscopic analyses we demonstrated that the m-THPC@BSA complex exhibits improved photophysical characteristics, essential for effective PDT. Notably, the complex showed a significant restoration of the singlet oxygen quantum yield (ΦΔ = 0.21) compared to aggregated m-THPC. These results underscore the potential of BSA to preserve the monomeric form of m-THPC, mitigating aggregation-induced losses in singlet oxygen production. Our findings suggest that BSA-mediated delivery systems could play a crucial role in optimizing the clinical utility of hydrophobic photosensitizers like m-THPC.

Abstract

Background: Persons living with HIV (PLWH) have a higher risk of persistent infection with human papillomavirus (HPV) and anal cancer. We evaluated knowledge and awareness of HPV infection and risk factors for anal cancer among PLWH in Puerto Rico (PR).
Methods: Data from a cross-sectional study (2020-2021) were analyzed (n=212). Inclusion criteria included PLWH, aged ≥ 26 years, and living in PR. Telephone interviews collected information on sociodemographic, lifestyle and clinical characteristics. Two 13-item scales were used to assess knowledge of HPV and anal cancer risk factors; adequate knowledge for both scales were defined as scoring >70%. Logistic regression models using generalized linear models were used to determine the association between 1) HPV infection awareness, 2) HPV infection knowledge, and 3) Anal cancer risk factors knowledge.
Results: The median age was 54 years (IQR: 46,58), 67.5% were male, 71.7% reported having an income <$20,000, and 54.3% had an education level of more than high school. HPV awareness was high (82.1%), but only 40.2% and 3.8% had adequate knowledge of HPV and anal cancer risk factors, respectively. In adjusted logistic regression models, men who have sex with men (OR: 1.26, 95%CI: 1.07-1.47) and women (OR: 1.35, 95%CI: 1.15-1.59) aged ≥50 years had higher odds of HPV awareness than heterosexual men in that age group. Moreover, those with history of anal Pap test aged <50 years had more HPV awareness (OR 1.34, 95%CI: 1.08-1.66) than their counterparts. Adequate HPV knowledge was higher among participants with an education level of more than high-school (OR:1.28, 95%CI: 1.10-1.50) and with a history of HPV diagnosis (OR:1.33, 95%CI: 1.08-1.65) than their counterparts. In addition, people with good/very good/excellent health perception had higher odds of HPV knowledge (OR:1.23, 95%CI: 1.03-1.47) than those who reported poor/regular health perception. For anal cancer risk factors, PLWH for ≥15 years had increased odds of having adequate knowledge (OR:1.07, 95%CI: 1.02-1.14) than their counterparts.
Conclusions: Despite high awareness of HPV, limited knowledge about HPV and anal cancer risk factors was observed among PLWH. Results from our study highlight the need for educational efforts within this population as an anal cancer prevention strategy.

Abstract

The increasing use of pesticides worldwide has raised concerns about their impacts on biodiversity, ecosystems, and human health, particularly for populations residing near agricultural regions. This study presents a novel spatially explicit risk indicator to assess residential pesticide exposure using detailed plant protection product data from France. By integrating spatial datasets and exposure assessment methodologies, we generated a high-resolution map that illustrates potential pesticide loads at the parcel level. Coupling this map with population distribution data enabled the monitoring of non-dietary pesticide exposure patterns. Findings indicate that approximately 13% of the French population may be exposed to pesticides due to their proximity to treated crops, with exposure levels varying from low to high (74% and 26% of the population respectively). This risk indicator highlights the effectiveness of detailed pesticide data in tracking and mitigating risks and can help identify regions where sustainable farming practices should be intensified. In addition, this method is scalable and can be adapted for use in other countries to improve pesticide risk monitoring and management in Europe and globally.

Abstract

Background and objective
: People with Chronic Kidney Disease (CKD) generally has malnutrition and decrease immune system due to lower food intake and inflammation. To address the progression of CKD, the Neutrophil-to-Lymphocyte Ratio (NLR) has been identified as an independent risk factor. The decrease in short-chain fatty acids (SCFAs) in the feces and serum of CKD patients during disease progression suggests a link between gut microbiota and CKD. We proposed administering Extra Virgin Olive Oil (EVOO) to explore the impact of the intervention CKD patients and effects on inflammation and gut microbiota.
Methods
This study was randomized clinical trial design by the administration of EVOO. Thirty participants were taken from CKD patients undergoing hemodialysis (HD). The intervention group (15 participants) was administered with EVOO 40ml for 2 weeks, and 15 participants as a control group without EVOO. Body mass index was measured using anthropometric (body weigth dan heigth), NLR were taken from red blood cell and SCFA using prohealthy gut examination,
Results
the study showed there were no differences between two group on nutritional status (both had normal status). Level of NRL significantly differents pre-and-post in intervention group, (5.07 ± 7.35 vs 2.74 ± 2.18 p = 0.007), not for control group ( 3.86 ± 2.21vs 4.26 ± 2.56 p = 0.196). There are not significant result for SCFA for intervention group (8.31 ± 3.77 vs 8.92 ± 3.88 p = 0.670). and control group (11.50 ± 4.80 vs 11.50 ± 3.86 p = 0.550). in addition, this study shown significant increased of energy intake, and carbohydrate on intervention group not in control group (p < 0,005).
Conclusion
This study reported the differences of NLR and SCFA levels and food intake in both groups, NLR as inflammatory markers significantly decreased in intervention group after 2 weeks of EVOO administration, while increased in control group. Moreover, EVOO affected Short SCFA levels in the gastrointestinal tract.

Published: June 2024

Abstract

Background
Primary dysmenorrhea (PD) is one of the most common gynecological complaints in women of childbearing age, which severely impacts their quality of life.
Objective
The study aims to investigate the prevalence of dysmenorrhea among women of different ranges of Body Mass Index (BMI) and its associated risk factors.
Methodology:
250 students (aged 18–24) from three medical colleges; Army Medical College, Foundation University Medical College, and Rawalpindi Medical University, participated in this cross-sectional survey. They were subjected to a pretested and structured questionnaire comprising 30 questions regarding their menstrual characteristics, risk factors of dysmenorrhea, and their weights and heights. BMI was calculated. Descriptive and analytical statistics were conducted using chi-square and ANOVA. A p-value of < 0.05 was considered statistically significant.
Results
Based on this study, 88.4% of the students had PD, with 19% having mild, 45.2% having moderate, and 35.7% having severe dysmenorrhea. 78% of the students stated that dysmenorrhea makes it difficult for them to go about their everyday lives. Among the risk factors, family history, and intensity of bleeding were statistically significant. Any relation between age at menarche and duration of menstruation was not established. Among the modifiable factors i.e. diet, sleep, stress, and exercise, only sleep was considered statistically significant. Chiefly, no association was found between BMI and intensity of dysmenorrhea.
Conclusion
A high prevalence of PD was detected among young women between 18–24 years of age. Family history, intensity of bleeding, and an inactive lifestyle were found to be the important risk factors for PD. However, no correlation was observed between BMI and PD.

Abstract

Artificial fruit ripening agents have become increasingly popular in recent years. During the off-season, various ripening agents are used for the ripening of banana fruits. This experiment was carried out under the study entitled “Effect of different post-harvest practices on quality of banana (G9) in Chitwan” for controlling the ripening of the banana, for improvement of quality attributes and post-harvest life of banana. The experiment was conducted at the laboratory of Horticulture, Agriculture and Forestry University, from 14th June to 16th August 2022. These experiments were laid out in a Completely Randomized Design in which the experiment comprised of five treatments dipping in distilled water, hot water treatment at 55℃ then covered with a jute sack, perforated plastic, ethephon 600 ppm, and, ripening chamber with four replications. Different post-harvest parameters were recorded at the interval of three days. In this experiment, the maximum physiological loss in weight, TSS, the highest color score, pH, TSS/TA, and Pulp peel ratio were observed in bananas sprayed with distilled water. In contrast, the minimum values for TSS, pulp peel ratio, Peel color rating, and TSS/TA were observed in Jute sack-covered fruits. Maximum and minimum shelf life were observed in jute sack-covered fruits and bananas sprayed with ethephon @600 ppm respectively. In summary, the present study showed some innovative post-harvest practices that enhance food security, promote responsible consumption, reduce environmental impact, and align with multiple SDGs, ultimately fostering a more sustainable and food-secure future.
First-principles study of electronic band structures in three magnetic orders and optical properties of YOX (F, Cl, Br) two-dimensional system employing density functional theory
Authors: Barhoumi Mohamed 
Published: June 2024

Abstract

The study of 2D materials is an active field. Here we investigate the electronic band structures of 2D YOX (F, Cl, Br) in three magnetic orders, including ferromagnetic and antiferromagnetic. Their optical properties are calculated employing first-principles calculations. The cohesive energies of 2D YOX obtained are comparable to those of two-dimensional graphene. Our two-dimensional single-layer structures demonstrate no unstable phonon modes, indicating they are dynamically stable. Our HSE calculations show that these materials are wide-band-gap semiconductors. The charge and spin densities are localized on the Y atoms. The spin-up and spin-down contributions are symmetrical in NM, FM, and AFM magnetic orders, and there are forbidden states between valence and conduction bands. This shows that YOX exhibits a non-magnetic behaviour. The Eg energies obtained with the magnetic order FM and AFM on all atoms are similar to those obtained in the case of the magnetic order FM and AFM only on the Y atoms. Besides, these systems become transparent when the incident light’s frequency exceeds the plasma frequency (30.00 eV), and a strong absorption appears in their spectrum. Our findings demonstrate that the tunable bandgaps and atomic-level thickness of the two-dimensional compound materials make them attractive candidates for numerous applications, such as electronics, optoelectronics, sensors, and flexible devices.
Dialéctica del estallido social en Colombia 2021: ecosistema de la contienda política-económica inherente al capitalismo-imperialismo. Contribución al análisis de la coyuntura generada por la movilización popular entre abril y julio de 2021 en Colombia
Authors: Lince Bohórquez Wilmar 
Published: June 2024

El texto que se presenta a continuación es la segunda entrega del análisis de la coyuntura estallido social 2021. Recuérdese que el primero se centró en los detonantes del estallido. El segundo artículo abordará algunos de los actores-sujetos más destacados de las movilizaciones: Comité Nacional de Paro, estudiantado universitario, profesorado universitario, campesinado, comunidades indígenas, organizaciones afrodescendientes, primeras líneas y gobierno. Se trata de diseccionar este conjunto de actores desplegando el método dialéctico materialista en perspectiva del análisis de coyuntura político-económico. Previo a la disección, se elabora una breve disertación acerca de la noción actor en perspectiva sociológica, con el ánimo de mostrar que, desde esta disciplina científica, la acción del sujeto está imbricada a la estructura. Este principio aplica para los actores del estallido social y, por tanto, se entiende que aun cuando diseccionados, lo estructural les atraviesa y subsume. En la reconstrucción analítica de cada actor predomina una lectura crítica que reconoce las proezas y fuerzas de sus luchas y, al tiempo, pondera sus limitantes y delimitaciones políticas y teóricas.

Published: June 2024

Introduction
A clear communication between healthcare providers and patients is crucial. However, challenges arise due to medical jargon, particularly for non-native English speakers, potentially affecting patient outcomes. This study assessed patients' understanding of oral medicine terms to improve clarity in patient-dentist interactions, decision-making, and overall patient well-being.

Methods
A self-administered cross-sectional survey was conducted between November 2022 and June 2023, targeting adult patients visiting dental clinics at King Abdulaziz University. Participants completed an 11-term questionnaire to evaluate their understanding of commonly used medical terminology in oral medicine.

Results
A total of 286 participants were included, 66.4% men, with a mean age of 43.4 years and 82.9% having a university education. In understanding oral medicine terminologies, for terms such as “tumor,” 70.3% understood it as a mass that could be cancerous, while 88.1% correctly defined “cancer.” Diagnostic terms such as “biopsy” were correctly identified by 56.3% of participants. Men demonstrated a higher average score (7.88±2.27) than men (6.16±3.00, P < 0.001). Age groups showed varied understanding, but there was no statistically significant difference in the overall knowledge score. Participants with a scientific background had a notably higher overall knowledge score (8.01±2.75) compared to those without (6.23±2.79, P < 0.001) it.

Conclusion
This study revealed inadequacies in dental clinic patients' grasp of translated oral medicine terms, particularly among non-native English speakers. Higher knowledge ratings among women and those with a scientific background highlight the value of face-to-face questionnaires that enable the interviewer to clarify and follow up on specific topics as needed. Thus, it enhances patient-dentist interactions in dental treatment.
