Factors influencing tourists’ intention to adopt classified garbage cans in tourism destination
Tourists who dispose of their trash properly can reduce the environmental problems caused by careless disposal and improve the effectiveness of recycling reusable things, both of which are essential for the pro-environmental growth of tourist attractions. Therefore, it is critical to classify waste in tourist areas so that travelers can practice pro-environmental activity. Few studies, however, have looked on how tourists feel about adopting classified trash cans in tourist destinations. This study examines the relationship between four types of value (altruistic value, biospheric value, collectivistic value, hedonic value), ecological worldview, three types of images (cognitive image, affective image, overall image) and intention to use classified garbage cans. A total of 407 respondents were collected in Taiyuan Ancient County Town via an online survey. Tests of the proposed hypotheses were conducted using SPSS and AMOS, and results showed that altruistic value, biospheric value and collectivistic value positively influenced ecological worldview, and subsequently, influenced cognitive image and affective image respectively. Affective image influenced overall image, while cognitive image has a significant influence on affective image and on overall image. In addition, hedonic value positively influenced cognitive image, and overall image positively influenced intention to use classified garbage cans. Finally, the theoretical, practical implications and limitations were discussed accordingly
Lifestyle management of hypertension: International Society of Hypertension position paper endorsed by the World Hypertension League and European Society of Hypertension
Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools
Synthesis, spectral characterisation, biocidal investigation, in-silico and molecular docking studies of 4-[(2-chloro-4-methylphenyl)carbamoyl]butanoic acid derived triorganotin(IV) compounds
Three triorganotin(IV) compounds, R3Sn(L), with R = CH3 (1), n-C4H9 (2) and C6H5 (3), and LH = 4-[(2-chloro-4-methylphenyl)carbamoyl]butanoic acid, were prepared and confirmed by various techniques. A five-coordinate, distorted trigonal-bipyramidal geometry was elucidated for tin(IV) centres both in solution and solid states. An intercalation mode was confirmed for the compound SS-DNA interaction by UV-visible, viscometric techniques and molecular docking. MD simulation revealed stable binding of LH with SS-DNA. Anti-bacterial investigation revealed 2 to be generally the most potent, especially against Sa and Ab, i.e. having the lowest MIC values (≤0.25 μg/mL) compared to the standard anti-biotics vancomycin-HCl (MIC = 1 μg/mL) and colistin-sulphate (MIC = 0.25 μg/mL). Similarly, the anti-fungal profile shows 2 exhibits 100% inhibition against Ca and Cn fungal strains and has MIC values (≤0.25 μg/mL) comparatively lower than standard drug fluconazole (0.125 and 8 μg/mL for Ca and Cn, respectively). Compound 2 has the greatest activity with CC50 ≤ 25 μg/mL and HC50 > 32 μg/mL performed against HEC239 and RBC cell lines. The anti-cancer potential was assessed against the MG-U87 cell line, using cisplatin as the standard (133 µM), indicates 2 displays the greatest activity (IC50: 5.521 µM) at a 5 µM dose. The greatest anti-leishmanial potential was observed for 2 (87.75 at 1000 μg/mL) in comparison to amphotericin B (90.67). The biological assay correlates with the observed maximum of 89% scavenging activity exhibited by 2. The Swiss-ADME data publicised the screened compounds generally follow the rule of 5 of drug-likeness and have good bioavailability potential
Association of microRNA-21 expression with breast cancer subtypes and its potential as an early biomarker
Breast cancer has become the most diagnosed cancer worldwide in 2020 with high morbidity and mortality rates. The alarming increase in breast cancer incidence has sprung many researchers to focus on developing novel screening tests to identify early breast cancer which will allow clinicians to provide timely and effective treatments. With much evidence supporting the notion that the deregulation of miRNAs (a class of non-coding RNA) greatly contributes to cancer initiation and progression, the promising role of miRNAs as cancer biomarkers is gaining traction in the research world. Among the upregulated miRNAs identified in breast carcinogenesis, miR-21 was shown to be significantly expressed in breast cancer tissues and bodily fluids of breast cancer patients. Therein, this review paper aims to provide an overview of breast cancer, the role and significance of miR-21 in breast cancer pathogenesis, and its potential as a breast cancer biomarker. The paper also discusses the current types of tumor biomarkers and their limitations, the presence of miR-21 in extracellular vesicles and plasma, screening methods available for miRNA detection along with some challenges faced in developing diagnostic miR-21 testing for breast cancer to provide readers with a comprehensive outlook based on using miR-21 in clinical settings
2D nanostructures: Potential in diagnosis and treatment of Alzheimer's disease
Two-dimensional (2D) nanomaterials have garnered enormous attention seemingly due to their unusual architecture and properties. Graphene and graphene oxide based 2D nanomaterials remained the most sought after for several years but the quest to design superior 2D nanomaterials which can find wider application gave rise to development of non-graphene 2D materials as well. Consequently, in addition to graphene based 2D nanomaterials, 2D nanostructures designed using macromolecules (such as DNAs, proteins, peptides and peptoids), transition metal dichalcogenides, transition-metal carbides and/or nitrides (MXene), black phosphorous, chitosan, hexagonal boron nitrides, and graphitic carbon nitride, and covalent organic frameworks have been developed. Interestingly, these 2D nanomaterials have found applications in diagnosis and treatment of various diseases including Alzheimer’s disease (AD). Although AD is one of the most debilitating neurodegenerative conditions across the globe; unfortunately, there remains a paucity of effective diagnostic and/or therapeutic intervention for it till date. In this scenario, nanomaterial-based biosensors, or therapeutics especially 2D nanostructures are emerging to be promising in this regard. This review summarizes the diagnostic and therapeutic platforms developed for AD using 2D nanostructures. Collectively, it is worth mentioning that these 2D nanomaterials would seemingly provide an alternative and intriguing platform for biomedical interventions
Tourism in Times of Crisis and Post-Crisis: A Model to Understand Tourists' Post-Pandemic Travel Intentions
The COVID-19 pandemic has had a profound effect on tourists' travel plans. Whilst the relationship between perceived risk and tourists' decisions and behaviours concerning COVID-19 is already an established research area in tourism studies, the dynamics of post-pandemic travel intentions and how they are influenced by travel motivation, destination safety and the notion of revenge tourism received very little attention. Therefore, this study proposes a model linking revenge tourism, destination safety, and travel motivations, leading to post-pandemic travel intentions. Furthermore, this research note lays a foundation for future research that can guide towards understanding tourists' travel intentions in times of crisis, similar to the COVID-19 pandemic
On the prediction of systemic risk tolerance of cryptocurrencies
The role of big data in finance is pivotal, especially in forecasting stock prices, mitigating risk, and assessing market anomalies. With the financial system becoming more interconnected, analytical models using large data are gaining prominence in developing risk spillover models. This study estimates the systemic risk tolerance of twenty-five high-valued cryptocurrencies and finds that Fantom has the highest tolerance, while Bitcoin and Ethereum have a lower tolerance due to their large market share. It also shows that the common trend of cryptocurrencies enhances each other's tolerance and develops a predictive model for systemic risk tolerance. The study can help investors and market participants devise strategies for safe haven investment, hedging, and speculation during a market downturn
Grooming: The threat is real
In today's digital age, child grooming has emerged as a chilling concern, magnified by the pervasive use of social media and online platforms among children.
Child grooming involves a predator establishing a relationship with a child over time, with the sinister intent of exploiting them for sexual purposes. Traditionally, one might imagine grooming occurring in physical spaces. However, the reality is that approximately 98% of grooming incidents now happen online

The present review suggests that the pharmacological properties of D. viscosa align well with its ethnomedicinal uses. These findings support the traditional use of D. viscosa in treating various illnesses. Additionally, toxicological examinations of D. viscosa extracts and essential oil have demonstrated the plant's safety, which supports the need for comprehensive pharmacological studies, in vivo studies, and clinical trials to evaluate the best doses for optimal medicinal effects. This work underscores the medicinal value of D. viscosa and its potential in developing new pharmacological agents to address major health challenges like antibiotic resistance and cancers
A structured laughter yoga therapy program on patients with chemotherapy-induced nausea and vomiting: A randomized clinical trial
Objetive
Chemotherapy is a prevalent cancer treatment, often accompanied by debilitating side effects such as nausea and vomiting. This study explores the potential effectiveness of laughter yoga, a combination of exercise and voluntary laughter, in alleviating chemotherapy-induced nausea and vomiting.
Methods
This two-group randomized clinical trial was conducted on 69 cancer patients undergoing chemotherapy at the Reza Chemotherapy and Oncology Center, Mashhad, Iran, in 2018. Patients were randomly divided into intervention and control groups. Both groups received routine self-care training, with the addition of four 20-min to 30-min laughter yoga sessions held immediately before one of their chemotherapy appointments for the intervention group only. Nausea and vomiting were assessed using the Morrow Assessment of Nausea and Emesis questionnaire at two stages, before and after the intervention. Data were analyzed with Chi-square, Independent-t, Mann–Whitney, Wilcoxon, and McNemar tests using Statistical Package for the Social Sciences (SPSS).
Results
The mean age of patients in the intervention group was 49.0 ± 9.6 years, while in the control group, it was 45.2 ± 12.6 years. The intragroup comparison showed a statistically significant decrease in the severity and duration of nausea in the intervention group and a statistically significant increase in the severity and duration of nausea in the control group from pre-test to post-test (P < 0.05). The intergroup comparison showed no statistically significant difference between the two groups in terms of vomiting conditions.
Conclusions
Laughter yoga demonstrates promise in improving chemotherapy-induced nausea, suggesting its potential recommendation for managing this distressing side effect. Further research is warranted to explore its broader application in cancer care.
