Optogenetics in oral and craniofacial research.

Optogenetics combines optics and genetic engineering to control specific gene expression and biological functions and has the advantages of precise spatiotemporal control, noninvasiveness, and high efficiency. Genetically modified photosensory sensors are engineered into proteins to modulate conformational changes with light stimulation. Therefore, optogenetic techniques can provide new insights into oral biological processes at different levels, ranging from the subcellular and cellular levels to neural circuits and behavioral models. Here, we introduce the origins of optogenetics and highlight the recent progress of optogenetic approaches in oral and craniofacial research, focusing on the ability to apply optogenetics to the study of basic scientific neural mechanisms and to establish different oral behavioral test models in vivo (orofacial movement, licking, eating, and drinking), such as channelrhodopsin (ChR), archaerhodopsin (Arch), and halorhodopsin from Natronomonas pharaonis (NpHR). We also review the synergic and antagonistic effects of optogenetics in preclinical studies of trigeminal neuralgia and maxillofacial cellulitis. In addition, optogenetic tools have been used to control the neurogenic differentiation of dental pulp stem cells in translational studies. Although the scope of optogenetic tools is increasing, there are limited large animal experiments and clinical studies in dental research. Potential future directions include exploring therapeutic strategies for addressing loss of taste in patients with coronavirus disease 2019 (COVID-19), studying oral bacterial biofilms, enhancing craniomaxillofacial and periodontal tissue regeneration, and elucidating the possible pathogenesis of dry sockets, xerostomia, and burning mouth syndrome.

Health Risk Assessment of Road-Dust-Bound Heavy Metals via Ingestion Exposure from One Typical Inland City of Northern China: Incorporation of Sources and Bioaccessibility

Heavy metals in road dust pose potential health risks to humans, while oral bioaccessibility and sources are all important factors influencing this health risk. However, few prior studies have combined them for health risk analysis. In this study, road dust samples were collected from different geographical locations of Jinan (west area, WA; central area, CA; and east area, EA) to analyze the source-specific and bioaccessibility-based health risks of heavy metals. The mean concentrations of heavy metals in the three areas were CA > EA > WA, with Cd, Cu, Mn, Pb, and Zn exceeding their corresponding background values. A source analysis using a Positive Matrix Factorization (PMF) model showed that traffic emissions were the main source of heavy metals in the WA and CA, while industrial activities were the main source in the EA. The mean bioaccessibility of heavy metals extracted using the Solubility Bioaccessibility Research Consortium (SBRC) method followed the order of Cd (75.5%) > Zn (42.2%) > Mn (42.1%) > Pb (42.0%) > Cu (32.9%) > As (23.6%) > Ni (20.1%) > V (16.8%) > Cr (13.3%). According to the combined source analysis, traffic was the primary risk factor in the WA (54.5 and 58.3% of NCR and CR, respectively) and CA (61.8 and 51.2%), with solid waste being the main risk factor in the EA (41.9 and 51.3%). In oral bioaccessibility testing, lower non-carcinogenic (<1.0) and carcinogenic risks (<1 × 10−6) of heavy metals were observed than those based on the total metal content. More importantly, As (43.4%) was replaced by V (29.7%) as the main contributor to NCR. Source-specific and bioaccessibility-based health risk assessments can accurately identify priority pollutants and heavy metals in urban road dust that need to be controlled. This provides more effective and accurate urban environmental risk management recommendations for sustainable urban development and population health.

Pannexin1 deletion in lymphatic endothelium affects lymphatic function in a sex-dependent manner.

The lymphatic network of capillaries and collecting vessels ensures tissue fluid homeostasis, absorption of dietary fats and trafficking of immune cells. Pannexin1 (Panx1) channels allow for the passage of ions and small metabolites between the cytosol and extracellular environment. Panx1 channels regulate the pathophysiological function of several tissues in a sex-dependent manner. Here, we studied the role of Panx1 in lymphatic function, and potential sex-dependent differences therein, in Prox1-CreERT2Panx1fl/fl and Panx1fl/fl control mice. Panx1 expression was higher in lymphatic endothelial cells (LECs) of male mice. Lymphatic vessel morphology was not affected in Prox1-CreERT2Panx1fl/fl male and female mice. Lymphatic drainage was decreased by 25% in male Prox1-CreERT2Panx1fl/fl mice, but was similar in females of both genotypes. Accordingly, only male Prox1-CreERT2Panx1fl/fl mice exhibited tail swelling, pointing to interstitial fluid accumulation in males upon Panx1 deletion in LECs. Moreover, serum triglyceride and free fatty acid levels raised less in Prox1-CreERT2Panx1fl/fl mice of both sexes in an oral lipid tolerance test. Finally, the percentage of migratory dendritic cells arriving in draining lymph nodes was increased in Prox1-CreERT2Panx1fl/fl female mice, but was comparable between male mice of both genotypes. Our results point to a LEC-specific role for Panx1 in the functions of the lymphatic system.

Whole-Genome Sequencing of Three Lactiplantibacillus plantarum Strains Reveals Potential Metabolites for Boosting Host Immunity Safely.

In response to the growing demand for immune-related products, this study evaluated the safety and immune-modulating potential of three newly discovered Lactiplantibacillus plantarum strains (GKM3, GKK1, and GKD7) through toxicity tests and whole-genome sequencing. Safety evaluations, including the analysis of antimicrobial resistance genes, virulence factors, plasmids, and prophages, classified these strains as safe for human consumption. Acute oral toxicity tests further supported their safety. To evaluate their immune-modulating potential, dendritic cells were exposed to these strains, and the secretion of key cytokines (IFN-β and IL-12) was measured. Among the strains, GKK1 exhibited the highest enhancement of IFN-β and IL-12 production, suggesting its potential as an immune-stimulating probiotic. Bioinformatics analysis revealed potential metabolic pathways and secondary metabolites, including predicted bacteriocins, associated with immune modulation. The presence of a nitrate reductase region in the GKK1 strain indicated its ability to produce nitric oxide, a critical molecule involved in immune regulation and host defense. The presence of glucorhamnanrelated gene clusters in GKK1 also suggested immune-enhancing effects. Nitrate reductase expression was confirmed using qPCR, with the highest levels detected in GKK1. Moreover, this study is the first to show an anti-inflammatory effect of plantaricin A, linked to its presence in strain GKM3 and its potential therapeutic applications due to sequence similarity to known antiinflammatory peptides. Overall, these three L. plantarum strains demonstrated a safe profile and GKK1 showed potential as an immunity-enhancing probiotic. However, additional investigation is required to confirm the involvement of specific metabolic pathways, secondary metabolites, and bacteriocins in immune responses.

Competency and recognition of the halal supervisor in Brunei Darussalam

Inefficient and inadequate qualification assessment for the requirements of halal supervisors has attracted more attention in the halal industry field, which led to the withdrawal of the halal certificate following the discovery that the restaurant violated halal certification requirements. Furthermore, there is a lack of research discussing the halal supervisor's credibility procedure in Brunei Darussalam. This research aims to identify the efficiency and adequacy of the current qualification assessment for the requirements for halal supervisors by Syariah principles and laws in Brunei. This research adopted a qualitative method, using a semi-structured interview and library research method. The finding reveals that a halal supervisor is qualified by passing a written and oral test prepared by the Halal Food Control Division (HFCD), with supplementary talks or briefings given. However, no specific halal training is offered to halal supervisors. This finding indicated the need to improve the qualification system. It can aid in suggesting the necessary ecosystem for the credibility of the competency and recognition of the qualification of a halal food supervisor. This study can benefit future research and industrial players and improve the qualification procedure for halal supervisor.

Exploring the relationships between ASS indices and CAF and the impact on Chinese college students’ oral English performance

Automatic Speech Scoring (ASS) has increasingly become a useful tool in oral proficiency testing for Second Language (L2) learners. However, limited studies investigate the alignment of ASS indices with the Complexity, Accuracy, and Fluency (CAF)—the three dimensions in evaluating L2 speakers’ oral proficiency, and the subsequent impact indices on the oral performance of Chinese college students. To bridge this gap, this study used comparative analysis, Pearson analysis, and linear regression analysis to delve into the relationship and correlations between paired ASS indicators of “pronunciation”, “fluency”, “integrity”, “speed”, “duration”, and “overall”, while also analyzing the relationships between “overall” and other variables. These analyses were conducted using 956 audio clips of freshmen who took the College English Test-Spoken English Test Band 4 (CET-SET-4) in May 2022 in China. The findings reveal that (1) the ASS indicators and evaluation methods are similar but not identical to those employed in prior studies; (2) “pronunciation” encapsulates both the accuracy and fluency dimensions of CAF; (3) “pronunciation” and “integrity” have significant impacts on Chinese college students’ oral English performance in read-aloud tasks. The study suggests that future research should further investigate the specific pronunciation challenges faced by Chinese college students, such as phonetics, stress, and intonation. Additionally, it highlights the need to comprehend teachers’ attitudes and preferences towards ASS to enhance its effectiveness in assessing second language (L2) learners’ oral proficiency. The study would provide some references to teachers for oral English teaching design and students for their self-assessment of oral English proficiencies.

Patterns of interaction in a paired speaking test: comparing L1 and L2 interactions

The shift of focus from a cognitive to social view has drawn the attention of second language assessment researchers to delve into interactional competence as an intriguing topic in paired oral tests. To fill the gap on how interactional patterns compare across L1 and L2 interactions this study was specifically set to explore and compare 45 paired interactions of L1 English speakers, L1 Persian speakers, and L2 English learners. While the findings indicated that the collaborative pattern was the most common pattern in the three groups less than half of the interactions in total were collaborative. Furthermore, not all the interactional patterns were found in all the groups. The frequency and prominence of the common patterns also varied. The findings could be explained by cultural norms of speech (e.g., in taking turns) and interlocutor effects (e.g., dominating the conversation or adopting a passive role). The findings imply challenges for fair assessment when using paired tasks as assessment tools. Furthermore, the findings call for rubric development and rater training programs to include description and discussion of interactional patterns to help raters improve their understanding and rating of paired interactions.

Pilot study on the relationship between oral function or subjective symptoms and appetite.

This pilot study evaluated the relationships between appetite and oral function, and between appetite and the subjective symptoms of decreased oral function. Seventy-one adult dental clinic patients (22 males, 66.0 ± 14.0 years) participated in this study. A Council on Nutrition Appetite Questionnaire score of ≤28 indicated anorexia, and the Mini Nutritional Assessment Short-form, body mass index and skeletal muscle mass index were used to define subject characteristics. Seven oral function tests and seven subjective symptoms related to oral function were evaluated. The relationship between subject characteristics, oral function tests, subjective symptoms and anorexia was analysed using the chi-square test and univariate and multivariate logistic regression. There were significant differences between the normal appetite group and the anorexia group for the 10-item Eating Assessment Tool (EAT-10) survey and the question 'Food remains in the oral cavity after eating' (p < .05). Univariate logistic regression found significant differences in the items of masticatory function, the EAT-10 survey and the question 'Food remains in the oral cavity after eating'. Multivariate logistic regression revealed significant differences in masticatory function (AOR 4.35; 95% CI: 1.03-18.35; p = .045) and EAT-10 (AOR 6.27; 95% CI: 1.40-24.02; p = .016). This pilot study investigated the influence of factors related to oral function on appetite. Relationships were found among poor masticatory function, poor swallowing function and anorexia.

Prevalence of insulin dysregulation in the non-obese stock-type horse and relationship with morphometric neck measurements

Insulin dysregulation (ID), core to equine metabolic syndrome, may present without obesity. Testing for ID risk is commonly based on breed and obese phenotype but might be valuable for non-obese stock-type horses. This study aimed to determine the prevalence of ID in non-obese stock-type horses and evaluate if morphometric neck measurements (MNM) correlate with ID. Sixty-two, non-obese (BCS 5, range 2.5-6/9) stock-type horses were assessed for MNM: neck circumference at 25%, 50% (NC50), and 75% (NC75) length, and crest height. An oral sugar test (OST; 0.15 mL/kg BW corn syrup) was performed with blood taken pre- and 60 min post-OST for insulin (PREI, POSTI) and glucose (PREG, POSTG). Insulin dysregulation was defined as insulin concentration > 45 µIU/mL POSTI. Three of 62 horses were ID (4.8%; 95% CI 1.0%-13.5%). Horses with ID had greater PREG (121.0 ± 7.56 vs. 105.3 ± 1.72 mg/dL; LS means ± SEM; P = 0.04) and PREI (15.7 ± 2.63 vs. 10.5 ± 0.59 µIU/mL; P = 0.05) than normal responders. Mares had greater PREI than geldings (11.7 ± 0.76 vs. 9.4 ± 0.89 µIU/mL; P = 0.04). Stepwise regression indicated a weak relationship with crest height and POSTG (y = 51.27 + (0.88 x NC50); R2 = 0.09; P = 0.02). Post-glucose correlated with NC50 (r = 0.30; P = 0.04) and NC75 (r = 0.29; P = 0.03). This study showed 4.8% of non-obese horses had ID, warranting testing irrespective of phenotype, but only a weak association between MNM and POSTG was found.

Antidyslipidaemic evaluation of coagulin C and withacoagulin isolated from Withania coagulans (Stocks) dunal berries in hypertension induced secondary dyslipidemia in albino mice

Vascular diseases like hypertension has often been associated with dyslipidemia. Sustained elevated blood pressure for not less than four weeks develops gross irregularities inside arteriolar lumen. The pathological changes might be due to intimal arteriosclerotic thickening causing tapering of the structural narrowing along the arterioles. It might also be due to occurrence of irregular damage in the vascular structure from focal arteriolar constriction and lead to secondary dyslipidemia. The pharmacological intervention may lead to rectification and therapeutic benefit against dyslipidemia.The withanolides coagulin C and withacoagulin were isolated by flash chromatography from the extracts of Withania coagulans (Stocks) Dunal berries. The withanolides were characterized using 1H NMR and 13C NMR, UV and mass spectrometry and confirmed as coagulin C and withacoagulin. The oral toxicity of coagulin C and withacoagulin were investigated in albino mice followed by their antidyslipidemic activity with two dose levels i.e. 25 mg/kg and 50 mg/Kg p.o. This dyslipidemia was secondary to hypertension which was developed by DOCA salt model (25 mg/kg; s.c.+ 2% NaCl). Mice were administered dose of 10, 50 and 500 mg/kg coagulin C and withacoagulin orally for 28 days daily for sub-acute toxicity effect.Coagulin C and withacoagulin were found to be tolerated upto 2000 mg/kg p.o. during acute toxicity study in mice. Coagulin C and withacoagulin were claimed to possess No-Observed Adverse Effect Level (NOEL) at the dose of 500 mg/kg orally. The high dose (50 mg/Kg) withacoagulin has highly significant difference in total cholesterol, triglyceride, HDL, LDL and VLDL levels in comparison to disease control group along with highly significant difference in triglyceride and VLDL level compared to animals of vehicle control group. Coagulin C at both the low (25 mg/Kg) and high dose (50 mg/Kg) have highly significant difference in comparison to vehicle control, disease control and positive control in controlling total cholesterol, triglyceride, LDL and VLDL levels in the experimental animals indicating that coagulin C is not much as effective as withacoagulin in the normalization of altered lipid profile of the experimental animals.On the basis of spectroscopic analysis the isolated compounds from Withania coagulans (Stocks) Dunal berries were confirmed to be coagulin C and withacoagulin. Acute oral toxicity test in mice was found to have safe profile even at high dose for both the compounds. On development of secondary dyslipidemia due to DOCA salt induced hypertension in albino mice, both the isolated compounds showed different degree of correction in the altered lipid profile of the animals. Whereas withacoagulin has been found to have more significant and successful in controlling the altered lipid profile, coagulin C has only marginal effect. The docking studies also confirm the result and hence it can be suggested that withacoagulin is better than coagulin C in managing the alteration of lipid profile of the experimental mice.

Low secondary risks for turkey vultures from a sodium nitrite toxic bait for wild pigs

AbstractAn acute and orally‐delivered toxic bait for wild pigs (Sus scrofa) containing sodium nitrite (SN) is being developed and tested for potential registration in the U.S. We evaluated oral toxicity of SN and risk of secondary consumption in a common avian scavenger, the turkey vulture (Carthartes aura), by 1) conducting an acute oral toxicity test (LD50) for turkey vultures by oral gavage, and 2) allowing turkey vultures to feed on whole carcasses and digestive tracts of wild pigs that died from consuming SN‐laden bait. Captive tests were conducted during fall 2016 and spring 2017 in the Wild Pig Research Facility at Kerr Wildlife Management Area, Hunt, Texas, USA. We estimated the LD50 of SN for turkey vultures at 659 mg/kg. None of the turkey vultures died or exhibited any symptoms of SN‐toxicity from consuming whole carcasses, or digestive tracts of wild pigs that were poisoned with SN. We concluded that the risks of secondary poisoning to turkey vultures are low, which agrees with previous work on another scavenger, the coyote (Canis latrans). Overall, we found no evidence to suggest that 2 common scavengers would be at risk of acute mortality from consuming wild pigs that were poisoned with SN.

TEACHING SPEAKING ABILITY OF VOCATIONAL HIGH SCHOOL STUDENTS THROUGH DIRECT NSTRUCTION MODEL

Through the use of oral tests to describe places described in descriptive texts, this study sought to investigate the efficacy of an instruction model combined with a learning model in enhancing the speaking abilities of Vocational High School (SMK) students. The goal of this study was to teach English speaking skills in a classroom setting. An experimental strategy with a pre- and post-test one group design was employed in the research methodology. Tenth grade TKJ students from Vocational High School PGRI Pangkalan Balai academic years 2023/2024 made up the research sample. Speaking exams were used to gather data both before and after the course of treatment. The speaking exam was divided into multiple parts, including fluency, grammar, vocabulary, and pronunciation. With an average pre-test score of 47.23% and an average post-test score of 64.3, the data analysis results demonstrated a considerable improvement in the speaking ability of students who received instruction through a direct instruction paradigm. This result demonstrates how well the learning model with direct instruction worked to enhance the speaking skills of students enrolled in vocational programs.

Soluble CD44 in oral rinses for the early detection of cancer: a prospective cohort study in high-risk individuals

BackgroundThere are 54,000 new cases of oral cavity and oropharyngeal cancer in the United States and more than 476,000 worldwide each year. Oral cavity and oropharyngeal squamous cell carcinoma make up most tumors with five-year survival rates of 50% due to prevalence of late-stage diagnoses. Improved methods of early detection in high-risk individuals are urgently needed. We aimed to assess the tumorigenic biomarkers soluble CD44 (solCD44) and total protein (TP) measured using oral rinses as affordable convenient screening tools for cancer detection.MethodsIn this prospective cohort study, we recruited 150 healthy current or former smokers through a community screening program. Baseline and four annual visits were conducted from March 2011-January 2016 with records followed until August 2020. Participants provided oral rinses, received head and neck exams, and completed questionnaires. SolCD44 and TP levels were measured and compared across groups and time. Participants were placed in the cancer group if malignancy developed in the study period, the suspicious group if physical exams were concerning for premalignant disease or cancer in the head and neck, and the healthy group if there were no suspicious findings. This analysis used two-sample t-test for comparison of means and two-sample Wilcoxon Test for comparison of medians. For subjects with follow-ups, estimated means of biomarkers were obtained from a fitted Repeated Measures Analysis of Variance (RANOVA) model including group, visit, and their interaction. Pairwise comparisons of mean solCD44 were made, including intergroup and intragroup comparison of values at different years.ResultsMost participants were males (58.7%), < 60 years of age. (90.7%), and Black (100%). Baseline mean solCD44 was elevated (2.781 ng/ml) in the cancer group compared to the suspicious group (1.849 ng/ml) and healthy group (1.779 ng/ml).ConclusionThis study supports the feasibility of a CD44-based oral rinse test as an affordable and convenient adjunctive tool for early detection of aerodigestive tract and other cancers in high-risk populations.

Impact of Air Bubbles on the Saltiness Perception of NaCl-Loaded Oleogel-Stabilized Water-in-Oil Emulsions.

Reducing salt intake without affecting the saltiness perception remains a great challenge for the food industry. Herein, the demulsification of water droplets and air bubbles was controlled to modulate the release of sodium from oleogel-stabilized water-in-oil emulsions (OGEs) stabilized by monoglyceride crystals. The effect of monoglycerides with carbon chain length (glycerol monolaurate-GML, glyceryl monostearate-GMS, and glycerol monopalmitate-GMP) and homogenization methods (hand-shaking or high-speed blender) on sodium release and saltiness was investigated by in vitro and in vivo oral processing tests. Milky-white stable emulsions were formed with both water droplets and air bubbles dispersing in the oil phase, regardless of the selected homogenization methods. Air bubbles were more unstable than water droplets during oral digestion. GML OGEs with more and larger air bubbles and the lowest hardness exhibited the highest sodium release rate and the strongest saltiness, independent of homogenization methods. The balance between air bubbles and water droplets in the GMS and GMP OGEs caused slower sodium release and lower saltiness. Overall, the presence of air bubbles in NaCl-loaded W/O oleogel-based emulsions was shown to have important implications for tailoring their sodium release and saltiness.

Effects of Chlorich®EnergyBoost on Enhancing Physical Performance and Anti-Fatigue Properties in Mice.

Chlorich®EnergyBoost, a water extract obtained from Chlorella sorokiniana, has been proposed to enhance physical performance and provide anti-fatigue effects. This study assessed the impact of Chlorich®EnergyBoost supplementation on physical performance and its anti-fatigue properties. Twenty-four mice were allocated into four groups: (1) the control group receiving only water,;(2) the 1X group (49.2 mg/kg/day); (3) the 2X group (98.4 g/kg/day); and (4) the 5X group (246 g/kg/day). All groups were orally administered the supplements for four consecutive weeks. The evaluation included grip strength, swimming endurance, an exhaustion test, and serum biochemistry analysis. Additionally, the study examined the bioactive peptides through matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS) and conducted bacterial reverse mutation and acute oral toxicity tests for safety assessment. The findings indicated that Chlorich®EnergyBoost supplementation led to a significant reduction in serum lactate levels by 14.08% to 22.54% and blood urea nitrogen levels by 12.23% to 16.76%, an increase in the lactate clearance rate by 0.28 to 0.35, an enhancement of muscle glycogen storage by 1.10 to 1.44-fold, and hepatic glycogen storage by 1.41 to 1.47-fold. These results demonstrated dose-dependent effects. MALDI-TOF analysis revealed the expression of dihydrolipoamide dehydrogenase and superoxide dismutase. Both the bacterial reverse mutation and acute oral toxicity tests showed no adverse effects.

Comparison of four confirmatory tests for the diagnosis of primary aldosteronism: Bayesian analysis in the absence of a gold standard.

Captopril challenge test (CCT), seated saline infusion test (SSIT), oral sodium loading test (OSLT) and fludrocortisone suppression test (FST) are widely used diagnostic tests for primary aldosteronism (PA). These tests differ in terms of safety and complexity. Whether the simpler tests (CCT and SSIT) are comparable in diagnostic performance to the more complex ones (FST and OSLT) is unclear. To compare the diagnostic accuracy of the four tests. This is a retrospective study of hypertensive patients who were screened for PA and completed at least one confirmatory test. The patients were divided into two cohorts: one including those who completed one to three tests was used for the estimation of sensitivity and specificity. The other including those who completed four tests was used for the comparison of accuracy. Bayesian method was used to obtain the sensitivity, specificity, and Youden index of each test. The study included 1011 hypertensive patients. Among them, 895 patients completed one to three tests (including 889 CCT, 605 FST, 611 SSIT and 69 OSLT), and 116 patients completed four tests. SSIT had the highest sensitivity of 0.82(95% CI 0.78-0.86) but the lowest specificity of 0.76(0.70-0.80). OSLT had the lowest sensitivity of 0.65(0.56-0.75) but the highest specificity of 0.91(0.82-0.96). The sensitivity and specificity were 0.78 (95% CI, 0.75-0.82), 0.82 (95% CI, 0.78-0.85), for CCT, and 0.77 (95% CI, 0.73-0.81), 0.87 (95% CI, 0.82-0.91) for FST, respectively. The Youden index was not significantly different among the four tests[0.60(0.55-0.65) for CCT; 0.58(0.51-0.64) for SSIT; (0.64(0.57-0.69) for FST; 0.56(0.43-0.67) for OSLT]. The accuracy of simpler tests is comparable to the more complex ones. Considering the safety and simplicity of CCT, it may be a reasonable first choice when confirming the diagnosis of PA.
