Here, we investigated and compared the sensitivity of TRPA1 and TRPV1 from various animals to astringent polyphenols. We selected three polyphenols, oxiEGCG, tannic acid and myricetin. HEK293T cells expressing TRPA1 or TRPV1 from mammal, bird, reptile, amphibian, and fish, were analyzed for their activation by the Ca²⁺-imaging. We found the apparent diversity in the polyphenol-sensitivity among various animals. Mammalian TRPs showed relatively higher sensitivity to polyphenols, and especially, human TRPA1 and TRPV1 could be activated by all of three polyphenols at 20 μM. Reptile TRP channels, however, were insensitive to any polyphenols examined. Moreover, the polyphenol-sensitivity of zebrafish TRPA1 and TRPV1 was quite different from that of medaka TRP channels. Since many polyphenols are present in plants and the sensing of polyphenols using TRP channels in the oral cavity might cause astringent taste, the observed diversity of the polyphenol-sensitivity of TRP channels might be involved in the divergence in the food habit of various animals.</p>","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25596522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanism underlying this undesired effect remains to be investigated. The homeostatic control of bone tissue depends on the interaction between osteoblasts and osteoclasts. Osteoprotegerin produced by osteoblasts is known to play an essential role in suppressing osteoclast induction. We have previously reported that prostaglandin (PG) E₂ and PGF_2α induce osteoprotegerin synthesis through p38 mitogen-activated protein kinase (MAPK), p44/p42 MAPK and stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) in osteoblast-like MC3T3-E1 cells. In the present study, we investigated the effects of acetaminophen on the osteoprotegerin synthesis induced by PGE₂ and PGF_2α in MC3T3-E1 cells. Acetaminophen significantly suppressed the osteoprotegerin release stimulated by PGE₂ and PGF_2α. The PGE₂-induced expression of osteoprotegerin mRNA was also reduced by acetaminophen. Acetaminophen markedly downregulated the phosphorylation of SAPK/JNK stimulated by PGE₂ and PGF_2α, but not those of p38 MAPK or p44/p42 MAPK. SP600125, an inhibitor of SAPK/JNK, suppressed the levels of PGE₂- and PGF_2α-upregulated osteoprotegerin mRNA expression. Taken together, these results strongly suggest that acetaminophen reduces the PGE₂- and PGF_2α-stimulated synthesis of osteoprotegerin in osteoblasts, and that the suppressive effect is exerted via attenuation of SAPK/JNK.

The expressions of TUG1 and osteogenic markers following the osteogenic induction of BMSCs were detected. The functional relevance of TUG1 was evaluated by performing gain- and loss-of-function tests. Inhibitors of AMP-activated protein kinase (AMPK) autophagy were applied to ascertain the effects of TUG1 on the osteogenic differentiation of BMSCs. TUG1 expression increased during the osteogenic differentiation of BMSCs. The overexpression of TUG1 was promoted, whereas the knockdown of TUG1 was suppressed, by BMSC osteogenic differentiation.

Blocking AMPK and autophagy could abrogate the osteogenic role of TUG1 in BMSCs.

As indispensable material for dental implant fixture, dental patients are exposed to its toxicological reactions. Objectives: The primary aim of this research is to prevent making nanoparticle titanium dioxide from the corrosion of dental implant fixture. Methods: The authors introduce double layer coating system for controlling corrosional toxicity of TiO2 from the surface of two dental implant fixtures by medronic acid and teriparatide acetate. Results: The first layer coated with medronic acid will generate phosphate bridges, functioning as a corrosionresistant sheath layer, and will be the only connector to Forteo (Teriparatide Acetate). The second layer encloses the essential elements of teriparatide like C, N, O and H with saving the functional radicals like CNO-, C2H3O-, CHO2-, C3H3O-, C2H3O2-,for and it will stimulate the coated implant fixture with PTH receptors, osteoblasts, and osteogenesis. The first layer covers Ti-O-P, acting as a titanium grade 4 antioxidant. Conclusion: The top surface ions in the second layer of the fixture have pharmaceutically functioning parts of the chemical structure of Teriparatide (C181H291N55O51S2) activating osteoblasts more than osteoclast, which leads to an overall increase in bone. Though the recommended duration of use for grade 4 implant fixtures is 3 years, but these new coated fixtures are expected to use the coated fixtures longer than 3 years by containing the stimulating effect of new alveolar bone formation by increasing the mineral density of the alveolar bone around the fixture besides preventing corrosional toxicity of the surface of pre-existing titanium fixtures.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81715198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vast majority of the powers applied in-vivo are dynamic and cyclic which implies frequently the tissue is under stacking and resting cycles. For instance femur and tibia go through cyclic pressure and elastic powers during motion. In this manner, it is conceivable that cells react more to cyclic stacking rather than consistent stacking. Consistent stacking may expand the danger of the cells being over-burden and getting inert to the applied burden. A vital zone of exploration in tissue designing is worried about finding the responses to how mechanical stacking moves to the cells, how cells sense mechanical powers and how and when cells react to the applied outer boosts. Both 2D and 3D societies have been utilized to apply mechanical stacking onto cells, albeit 2D examinations, for example, gelatine covered plastic and glass are to some degree restricted since they don't precisely copy the intricate 3D in-vivo engineering. Hence, these surfaces don't satisfy the vital necessities for culture and recovery of utilitarian tissues.

And medical students suffer more because during their training period they undergo a lot of stress in the form of little physical activity, altered food habits and social habits like smoking and alcohol. For this reason we decided to conduct this study amongst the medical students. Objective: Our objective of this study is to determine the prevalence of prehypertension among Medical college students and study the association between prehypertension and other cardiovascular risk factors like lipid profile and Body Mass Index (BMI). Methods: A total of 300 medical students of first to final year MBBS (18-23 years) were selected randomly for this study. Each participant’s data was collected, BMI calculated. BP was measured by a mercury sphygmomanometer. Subjects were classified as 3 groups Normotensive, Hypertensive and Prehyperensive. Blood samples were collected and Fasting plasma glucose, serum cholesterol, triglyceride and HDLc, were estimated by using commercially available kits in automated analyzer. Serum LDLc, and VLDLc (Very Low Density Lipoprotein-cholesterol) were calculated by Friedwald's equation. All the data were analysed by using SPSS software. Results: The overall prevalence of PHT was 38%. Prevalence of prehypertension is more in females. Among the students 75% had normal BMI, 20% were overweight, 3% were obese and 2% were underweight. BMI of Prehypertensive was significantly more than the normotensive students. BMI of female students are more than the male students. Among the lipid parameters, prehypertensives showed significant increase in TC, TG, LDLc than normotensive students. TC, TG, LDLc were high for female students than male students. Total prevalence of dyslipidaemia was 17.4% out of which 14.9% was hypercholesterolemia, 8.15% was hypertriglyceridaemia, 5.6% had high LDLc level and 10.4% had low HDLc level. There was a significant positive correlation between SBP with BMI, TG, TCh and VLDLc and significant positive correlation between DBP with TG and LDLc. There is negative correlation of SBP and DBP with HDLc. This might point out the contributory role of dyslipidemia and obesity towards prehypertention. Conclusion: Prevalence of prehypertension was high and associated with a higher BMI and dyslipidemia .Prevalence of dyslipidemia is 17.4%. Hypercholesterolemia is more prevalent. Students should change their life style. They should do yoga, meditation regularly to cope with stress. They should avoid oily foods to decrease cholesterol level.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83160690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
