    Heterotrigona itama stingless bee propolis extract is known for its diverse bioactive compounds, making it a potential natural shield against UV radiation. This research assesses the photoprotective potential of crude ethanol extract from H. itama propolis collected from four structures (involucrum, pillar, pot, and entrance) of five bee hives (H1-H5), totalling 20 samples. Initially, the samples underwent testing for SPF value and UV absorption spectra. The crude ethanol extract (E) from the involucrum (H4) with the highest SPF value and broadest spectrum was selected for fractionation using hexane and water. Subsequently, the extract (E) and its hexane (H) and water (W) fractions were subjected to SPF analysis, UVA/UVB absorption assessment, determination of total phenolic and flavonoid content, free radical scavenging capacity, anti-collagenase effects, and cytotoxicity assessment. Additionally, LC-MS/MS analysis was performed to identify chemical constituents in the active fraction (W). The extract E demonstrated an SPF of 8.23 ± 0.09 and UV absorption. Notably, its fraction W exhibited the highest SPF (16.55 ± 0.24) at 100 μg/mL, surpassing the H fraction (SPF 5.7 ± 0.45). Phenolic content was highest in the H fraction (388.95 ± 4.54 mg/g GAE DW), followed by the W fraction (286.76 ± 6.48 mg/g GAE DW) and crude E (91.83 ± 4.12 mg/g GAE DW) from the involucrum. Regarding flavonoids, the fraction W led with 79.82 ± 6.21 mg/g QE DW, followed by the H fraction (45.56 ± 0.05 mg/g QE DW) and E (34.57 ± 1.11 mg/g QE DW). The extract E also exhibited modest DPPH scavenging (EC50 = 120 μg/mL), while the H fraction demonstrated stronger activity (EC50 = 4.37 μg/mL), and the W fraction displayed moderate effects (EC50 = 17.55 μg/mL). Notably, the W fraction showed remarkable anti-collagenase activity, outperforming the positive control, EG. HaCaT cell cytotoxicity revealed that the extract E was cytotoxic, whereas the H and W fractions showed no toxicity. LC-MS/MS analysis identified bioactive flavonoids (e.g., pratensein, quercetin) in the W fraction. These findings highlight the superior photoprotective properties of the water fraction from the involucrum of H. itama stingless bee propolis extract, suggesting its potential as a natural and effective ingredient for sunscreen and skincare formulations.

    BACKGROUND: Clinical depression is a serious public health issue that affects 4.7 % of the world's population and can lead to suicide tendencies. Although drug medications are available, only 60 % of the depressed patients respond positively to the treatments, while the rest experience side effects that resulted in the discontinuation of their medication. Thus, there is an urgent need for developing a new anti-depressant with a distinct mode of action and manageable side effects. One of the options is using medicinal plants or plant-based traditional medicine as alternative therapies for psychiatric disorders.

    OBJECTIVES: Therefore, the objective of this review was twofold; to identify and critically evaluate anti-depressant properties of medicinal plants or those incorporated in traditional medicine; and to discuss their possible mechanism of action as well as challenges and way forward for this alternative treatment approach.

    METHODS: Relevant research articles were retrieved from various databases, including Scopus, PubMed, and Web of Science, for the period from 2018 to 2020, and the search was updated in September 2024. The inclusion criterion was relevance to antidepressants, while the exclusion criteria included duplicates, lack of full-text availability, and non-English publications.

    RESULTS: Through an extensive literature review, more than 40 medicinal plant species with antidepressant effects were identified, some of which are part of traditional medicine. The list of the said plant species included Albizia zygia (DC.) J.F.Macbr., Calculus bovis Sativus, Celastrus paniculatus Willd., Cinnamomum sp., Erythrina velutina Willd., Ficus platyphylla Delile, Garcinia mangostana Linn., Hyptis martiusii Benth, and Polygonum multiflorum Thunb. Anti-depressant mechanisms associated with those plants were further characterised based on their modes of action such as anti-oxidation system, anti-inflammation action, modulation of various neurotransmitters, neuroprotective effect, the regulation of hypothalamic-pituitary-adrenal (HPA) axis and anti-depressant mechanism. The challenges and future outlook of this alternative and complementary medicine are also explored and discussed.

    CONCLUSION: This pool of identified plant species is hoped to offer health care professionals the best possible alternatives of anti-depressants from natural phytocompounds that are efficacious, safe and affordable for applications in future clinical settings.

    Human milk Oligosaccharides (HMOs) are a major component in human milk and recognized to play an important role in modulating gut microbiota, intestinal cell response, and the development of the brain and immune system. While HMOs levels from Chinese mothers across different regions of China have been reported, data from Hebei are lacking. Twelve HMOs were measured from a cross-section of Hebei Han mothers over a 15-month lactation period. The average total of the 12 measured HMOs was 4872 ± 1902 mg/L, similar to that reported for Han mothers from other Chinese regions. Hebei Han mothers had much lower LNnT (59.0 ± 53.1 mg/L), LNFP II (257.5 ± 211.0 mg/L) and LNFP III (149.9 ± 121.7 mg/L) levels and higher 3FL levels (1875.2 ± 1065.3 mg/L) compared to other regional Chinese mother cohorts. The distribution of secretor and Lewis status for this Hebei mother cohort was measured at 68.5 %, 21.9 %, 8.2 % and 1.4 % respectively for Se+Le+, Se-Le+, Se+Le- and Se-Le- respectively. The results from this study suggest that location has influence over the HMOs concentration.

    Mies is a delicious honey wine traditionally processed in Ethiopia and Eritrea. This study aimed to investigate the standardization and characterization of high-quality Mies. The ingredients for Mies preparation were collected, and three formulations were created by varying the amounts of Gesho and honey. First, Birzi was made by dissolving honey in a 1:5 ratio (honey to water) and fermenting it at 22 °C for five days. Next, coarsely ground Gesho was added to the Birzi in plastic tanks, where it fermented for 14 days. The fermented mixture was then filtered through a clean white cotton cloth into a new plastic tank. The filtrate (Mies) was seasoned and fermented for an additional two days, after which its physicochemical, nutritional, sensory, and microbial properties were analyzed using standard methods. As fermentation time increased, the pH values of the three Mies formulations decreased from the first to the twenty-first day. The study revealed that as fermentation time increased, so did the temperature and alcohol levels in all three formulations. Formulation three (F3) was selected by the panelists as the highest quality Mies, with a temperature of 22.50 °C after 21 days. The alcohol content of F3 rose from 2.93 % on the first day to 5.72 % by the twenty-first day. The titratable acidity and total soluble solids of F3 were measured at 3.50 g/L and 26.24 °Brix, respectively. The nutritional contents of F3 included lipid (0.13 %), protein (0.10 %), and carbohydrates (3.02 %). The total energy of F3 was found to be 73.91 %. The study revealed that potassium (K) was the most abundant element in F3 and its ingredients, followed by phosphorus (P), while manganese (Mn) and zinc (Zn) were detected in the lowest amounts. Lactic acid bacteria (LAB) were identified as the predominant microbes in F3. Standardizing production procedures for Ethiopian honey wine can enhance commercialization and scalability, while its distinct flavors and fragrances can boost demand, profitability, and potential market entry. To improve the consistency and quality of honey wine production, further research is required to identify species-specific microbial profiles using molecular tools, optimize production parameters, and address concerns related to preparation.

    This paper investigates the procedure for determining the new Hijri Month between Brunei, Indonesia, Malaysia, and Singapore. It endeavours to understand the reason for dissimilarity in terms of practice between these four nations in commencing Hijri Month of Ramadan, Shawal, and Zulhijjah despite sharing the same lunar crescent visibility criterion. This study is conducted through the examination of literature with regards to regulations of the lunar crescent visibility criterion between these countries. The study finds out that the determination of the Hijri months, particularly Ramadan, Shawal, and Zulhijjah, varies among Malaysia, Indonesia, Brunei, and Singapore despite their shared criteria for the rest of the lunar calendar. Brunei relies on moon sightings coordinated by the Chief Syar'ie Judge and various governmental departments, culminating in approval by the Sultan. Indonesia conducts a comprehensive Sidang Isbat conference involving numerous religious and scientific bodies, with the final decision made by the Ministry of Religious Affairs. Malaysia's process involves Department of Islamic Development Malaysia (JAKIM) and multiple expert panels, with the final announcement made by the Keeper of the Ruler's Seal after royal consent. Singapore employs purely astronomical calculations using Unofficial Meeting of Religious Affairs Ministers of Brunei, Indonesia, Malaysia and Singapore (MABIMS) criteria without moon sightings due to environmental constraints. These countries' methods reflect their unique institutional, cultural, and religious contexts. Factors influencing these differences include reference points for lunar calculations, the principles of Islamic jurisprudence, and public comprehension. Indonesia's diverse demographic and significant influence from Muhammadiyah and Nahdlatul Ulama groups lead to varied practices. Malaysia experiences minimal impact from smaller groups but historically had a notable discrepancy in Ramadan 1983. Brunei's unified adherence to the Shafi'i School of Thought ensures consistency in moon sighting practices. Singapore's reliance on calculations is driven by its inability to perform moon sightings due to light and industrial pollution. The study concludes that while MABIMS countries aim for a unified lunar crescent visibility criterion, practical implementations remain distinct, leading to potential differences in the start of important Hijri months. The need for a unified reference point and further discussions among MABIMS officials is highlighted to achieve consistent Hijri month determinations.

    OBJECTIVE: and rationale: Odontogenic myxoma is an uncommon odontogenic tumor with locally aggressive behavior. The clinicopathological studies of odontogenic myxoma in Asian countries are very limited and only few studies have investigated the immunohistochemical profiles of the tumor. This study aims to investigate the clinicopathological and immunohistochemical features of odontogenic myxoma at the Faculty of Dentistry, Mahidol University over a 15-year period.

    METHODS: Archives of our institute were reviewed. Cases diagnosed as odontogenic myxoma were retrieved. Demographic, clinical, radiographic, and histopathological features of these cases were analyzed. In addition, immunohistochemical markers including vimentin, Ki-67, Bcl-2, and CD117 were performed. The correlation between immunohistochemical profiles and clinicopathological characteristics was evaluated.

    RESULTS: Sixteen cases of odontogenic myxoma were discovered. Fourteen cases were central type while two cases were peripheral type. The mean age of patients was 34.6 years with male-to-female ratio of 1:2.2. Mandible (68.8 %) was more affected than the maxilla (31.2 %). Bony expansion or jaw swelling (43.8 %) was the most common clinical feature. Most cases (71.4 %) presented with multilocular radiolucency. Histopathologically, tumors show stellate and spindle-shaped cells in a myxoid stroma with varying amounts of collagen fiber. All cases were positive for vimentin and Bcl-2. Half of the cases showed positive for Ki-67. Mast cells were presented in most cases (75.0 %). A significant correlation was found between the immunoexpression level of Bcl-2 and border of lesion in radiograph (p = 0.024).

    CONCLUSIONS: This study contributes to better understanding of the characteristics of odontogenic myxoma. Clinicians and pathologists should be aware of odontogenic myxoma, as its clinical and histopathological features may overlap with other tumors. The expression of Bcl-2 and presence of mast cell in this tumor may relate to its growth and aggressiveness. Despite its benign nature, odontogenic myxoma exhibits high recurrence, especially in lesion managed conservatively.

    This study investigates the use of various industrial waste materials-silica fume (SF), cement kiln dust (CKD), calcium carbide residue (CCR), rice husk ash (RHA), and ground granulated blast furnace slag (GGBS)-as eco-friendly stabilizers for expansive clay soil (ECS). Laboratory tests were conducted to assess the impact of different proportions (3 %, 6 %, and 9 %) of these additives on the soil's physical, mechanical, and microstructural properties. Results indicated that the inclusion of industrial waste significantly improved the soil's behavior, with notable reductions in liquid limit (up to 37.66 %), plasticity index (up to 74.76 %), and swell potential. Additionally, unconfined compressive strength (UCS) and shear strength increased substantially, with UCS values rising from 114.64 kPa to 1582.91 kPa at 30 days of curing for 9 % GGBS. Microstructural analyses confirmed the formation of cementitious compounds, which enhanced soil particle bonding and durability. These findings suggest that industrial waste materials can serve as effective and sustainable alternatives to traditional soil stabilizers, offering both performance improvements and environmental benefits.

    This paper examines the influence of the new 15 % Value Added Tax (VAT) enforcement on non-financial listed companies in Saudi Arabia. By comparing financial data from 2019, before the VAT implementation and the COVID-19 pandemic, with data from 2020, during both the VAT increase and the pandemic, the research aims to uncover the consequences of this tax policy change. Utilizing charts, tables, and an event study analysis approach with the Autoregressive Moving Average (ARMA) model, we investigated key financial indicators such as Shareholders' Equity (SE), Total Income (TI), Total Revenues (TR), Net Income (NI), Total Expenses (TE), Other Changes in Operating Activity (COA), and Cash at the End of the Period (CEP). The findings reveal significant financial impacts, highlighting companies' challenges due to the increased tax burden. Shareholders' Equity dropped from an average of 11.55 million to 4.57 million, and Total Income and Total Revenues decreased from approximately 1.73 million to 316,234 and from 1.95 million to 331,605, respectively. Net Income sharply declined from 406,109 to 74,624, and Total Expenses decreased from about 1.18 million to 223,495. Other Changes in Operating Activity shifted from a negative mean of -168,936 to a positive 523,520, and Cash at the End of the Period fell from 1.99 million to 666,663. These results suggest that the VAT increase has significantly strained companies' financial performance, emphasizing the need to consider such tax reforms carefully, particularly in developing countries. The study concludes that while the VAT increase aims to enhance government revenues, it imposes substantial financial strain on companies, potentially leading to long-term economic repercussions. Policymakers should consider these implications and implement practical measures to optimize the VAT system and support business resilience in the face of such reforms.

    AIM: This systematic review of clinical trial evidence aims to determine whether homeopathy can effectively relieve symptoms and reduce antibiotic use in patients diagnosed with otitis media (OM).

    METHODS: Seven databases and four trial registries were searched. Eligible studies included randomised- and non-randomised-controlled-trials in patients diagnosed with OM. Studies on Individualised- and non-Individualised-Homeopathy (IH, non-IH) were included, and controls were inactive and/or active treatment. Primary outcomes were clinical-improvement and antibiotic-use. Data extraction, Risk of Bias and certainty of evidence (GRADE) were performed using established methodology.

    RESULTS: Nine studies (IH = 4, non-IH = 5) comprising seven Randomised Clinical Trials (RCTs) and two non-RCTs (nRCTS) compared homeopathy with placebo (n = 2) or standard care (n = 7). 4/7 included RCTs reported statistically significant individual outcomes at relevant time points (symptom score, MEE, and antibiotic use) favouring homeopathy. However, heterogeneity of study designs, homeopathic interventions and outcome measures hindered the pooling of data for most outcomes, except for antibiotic use (non-IH). Add-on non-IH reduced filled antibiotic prescriptions by 46 % (RR = 0.54 [95%CI: 0.28, 1.06], P = 0.07, I2 = 12 %), but this did not reach statistical significance. Most studies demonstrated that the homeopathy group had less adverse events than the control group.

    CONCLUSIONS: The evidence base for the effectiveness of homeopathy and OM treatment is modest in study number, size, and risk of bias assessment. Individual RCTs report positive effects on clinical improvement and/or antibiotic use at relevant time points with homeopathy with no safety issues. Due to heterogeneity, the current evidence is insufficient to satisfactorily answer whether homeopathy is effective for clinical improvement and reducing antibiotic use in patients with OM. A Core Outcome Set for OM for future research is warranted to improve the potential for meta-analyses and strengthen the evidence base.

    Stem cell therapy and low-intensity extracorporeal shockwave (LI-ECSW) are recognized as potential restorative therapies and have been used in the treatment of erectile dysfunction (ED). Stem cell therapy is well-known due to its attributed regenerative ability and thus can help to improve erectile function in patients with vasculogenic ED. Besides, current evidence also shows that LI-ECSW therapy can help stimulate cell recruitment and proliferation and promote angiogenesis and vascularization in the damaged tissue. Hence, due to the therapeutic and restorative effects of both therapies, the success of ED treatment can be elevated through a combination therapy between stem cell therapy and LI-ECSW. In this review, a detailed description and efficacy discussion of combination therapies between different types of stem cells and LI-ECSW therapy are described. Besides, other potential cell types to use together with LI-ECSW are also listed in this review. Thus, this review provides better insight on the efficacy of combination therapy for ED treatment.

    This paper provides an in-depth review of the advancements and challenges associated with Titanium Matrix Composites (TMCs) in Selective Laser Melting (SLM). Material selection, SLM processing parameters, and their influence on the microstructure and properties of TMCs are discussed. The relationship between processing parameters, material characteristics, and the development of defects such as balling, porosity, and cracking is examined. Critical factors influencing the evolution of microstructure and defect formation in TMCs processed by SLM are highlighted. Strengthening mechanisms such as dislocation movements, grain refinement, the Orowan process, and load-bearing capacity are analyzed, and their roles in enhancing hardness, tensile strength, corrosion resistance, and wear resistance are explored. It is indicated by key findings that less than 5 % reinforcement content by volume can significantly enhance mechanical properties, achieving maximum hardness values of approximately 1000 HV and tensile strength close to 1500 MPa. However, this improvement is accompanied by a notable decrease in elongation. The importance of optimizing SLM parameters such as laser power, scan speed, hatch distance, layer thickness, and particle contents to minimize defects and enhance material performance is underscored. Existing research gaps in defect management and material distribution are identified. Future research directions on improving TMCs performance through advanced SLM techniques are suggested.

    The transition to electric vehicles (EVs) calls for sustainable advancements in automotive lubricants, as traditional fossil-fuel-based products pose environmental challenges. Palm oil-based biolubricants enriched with nanoparticles present a promising eco-friendly alternative that meets the thermal and tribological demands of EVs. This paper aims to analyze the development of nanoparticle-enriched palm oil-based biolubricants, aimed at improving the sustainability and performance of electric vehicle (EV) lubrication systems. The critical findings highlight that integrating nanoparticles such as graphene, titanium dioxide, and aluminum oxide into palm oil-based lubricants significantly enhances their tribological properties. These enhancements include a 26.21%-34% reduction in coefficient of friction (COF), a 12.99%-30% reduction in wear, and improved thermal stability. The study found that nanoparticle-enriched biolubricants outperformed traditional options in terms of friction and wear under high-temperature and pressure conditions, as supported by regression analysis. The study demonstrates that nanoparticle-enriched biolubricants offer a viable eco-friendly alternative to conventional lubricants, lowering the environmental impact by reducing greenhouse gas emissions and energy consumption. This innovation has significant implications for both the environment and industry, offering a sustainable solution that reduces dependency on fossil fuels, enhances EV efficiency, and aligns with global sustainability goals. Besides, this paper discusses biolubricants drawbacks and future studies direction.

    Deep eutectic solvents are a novel class of solvents that have gained much attention with time due to their biodegradability, non-volatility, non-toxicity and low-cost. In this work, a novel ternary deep eutectic solvent (TDES) was synthesized using ethaline (ChCl:EG) and glycine, with the addition of carboxylic acids. The synthesized material was characterized through Fourier-transform infrared spectroscopy (FTIR). While the thermal stability and physical properties such as density, viscosity, surface tension and refractive index were also determined). To estimate the critical properties, modified version of Lyderson-Joback-Reid (LJR) and Lee-Kesler mixing (Alkhatib et al., 2020) [1] methods were used. The density of the DES was calculated using the Spencer and Danner correlation and the obtained values were compared with experimental data. FTIR analysis confirmed that hydrogen bonding is the main driving force responsible for the formation of the deep eutectic solvents. The physical properties of the binary DES system, such as viscosity, density,and thermal stability of the system were enhanced after the incorporation of a third component (carboxylic acid) to the system. However, the surface tension of the TDES system decrease with the increasing amounts of the third component, likely due to increase in the void radius of the TDES. Thus investigation is considering as novel work to check the influence of carboxylic acids on the physical properties of binary deep eutectic solvent systems.

    BACKGROUND: Obstructive Sleep Apnea (OSA) is a temporary airflow obstruction during periods of sleep. Patients with OSA often suffer from poor work performance, compromised sleep quality, and low quality of life which may lead to a life-threatening event. Adequate knowledge and a positive attitude toward OSA among medical and dental practitioners are crucial to the initial diagnosis and treatment.

    OBJECTIVE: This study aimed to identify the differences in knowledge and attitude toward OSA between medical and dental practitioners working in North-Eastern Peninsular Malaysia.

    METHODS: A comparative cross-sectional study was performed from February 2020 to February 2021. A total of fifty-two medical practitioners and fifty-two dental practitioners working at university-based outpatient clinics, government health clinics, and oral health clinics located in Kelantan State of Malaysia participated in the study, and data were collected by the structured questionnaire including sociodemographic inquiry and OSAKA questionnaire by non-probability stratified random sampling. The Mann-Whitney U test was used to compare knowledge and attitude scores between the two groups.

    RESULTS: The mean age of the respondents was 34.6 years. The current study shows that 92.3% of medical doctors and 96.1% of dental doctors were able to correctly answer the question "Most of the patients with OSA snore" a significant finding in our study. Only 1% of medical professionals could answer seventeen questions correctly with a median score of 11, and only 1% of dental professionals could answer sixteen questions correctly with a median score of 9. None of them could provide an accurate answer to all the knowledge questions. Medical and dental practitioners exhibited different knowledge levels on OSA (z- statistics=-4.39, U = 827.00 with p <  0.05, and effect size, r = 0.61). However, no significant differences were found in total knowledge score by gender (p-value>0.05), ethnicity (p-value>0.05), total service years (p-value>0.05), and training attended. In addition, significant differences in attitude levels between medical and dental practitioners have been observed (z-statistics=-3.42, U = 725.00 with p <  0.05, and effect size, r = 0.47). Nevertheless, no significant differences have been seen in total attitude score by ethnicity (p-value >  0.05), total service years (p-value >  0.05), attending training on OSA (p-value >  0.05), and professional status (p-value >  0.05) except gender (p-value <  0.05).

    CONCLUSION: A Significant difference is evident concerning knowledge and attitude toward OSA diagnosis and management between medical and dental practitioners working in North-Eastern Peninsular Malaysia. Medical practitioners in this study recorded a higher knowledge and attitude score compared to dental practitioners.

    BACKGROUND: The global implementation of full-time telework became widespread during the new normal conditions following the pandemic, resulting in reduced physical activity (PA) among teleworkers and young adults. It is vital to comprehend how telehealth interventions favorably impact PA levels and overall well-being of young adults who face increasingly blurred boundaries between work and home life.

    OBJECTIVES: The aim of this study is to examine the effect of telerehabilitation (TR) on PA levels and quality of life (QoL) in young adult teleworkers.

    METHODS: A quasi-experimental study was conducted on 82 teleworkers (54 females and 28 males). Levels of PA and QoL were assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the Health-Related Quality of Life (HRQOL-14) questionnaire. TR was provided to all participants for four weeks, three times a week, for 40 minutes per session. Levels of PA and QoL were evaluated at baseline and after four weeks of the intervention. Data were analyzed using descriptive and inferential statistics.

    RESULTS: After four weeks of TR, there has been a significant improvement in the scores of IPAQ and HRQOL-14 (p

    Interpersonal distance (IPD) refers to the distance naturally maintained during social interactions, while peripersonal space (PPS) refers to the immediate space surrounding the body, or the space within reaching distance. Previous research has preliminarily indicated that IPD is associated with body image disturbances. We sought to expand extant literature by exploring associations between aspects of positive and negative body image, IPD, and PPS. Seventy-five women from the United Kingdom aged 18-40 years completed measures of body appreciation, body image flexibility, body shame, body surveillance, and body dissatisfaction. IPD boundaries were estimated using a lab-based comfort-distance task, whereas PPS boundaries were estimated using an audio-tactile reaction-time task. Measures of body acceptance by others and fear of negative evaluation were completed as potential mediators. Overall, we identified positive associations between IPD, body surveillance, and fear of negative evaluation, with no statistically significant associations identified between the other indices. The association between active IPD and body surveillance was mediated by fear of negative evaluation, even after controlling for demographic factors. These findings suggest a nuanced relationship between IPD and body image-related factors, highlighting the role of social evaluation anxiety. Future investigations should use experimental designs to further understand these relationships and their implications.
