Preconditioning of MSC in low oxygen concentration has been shown to affect the therapeutic potential of these cells. This study aimed to compare the characteristic and secretion of trophic factors of MSCs cultured under hypoxia and normoxia. Methods : MSCs were isolated from Wharton ' s jelly of human umbilical cord (UC) tissue by explant method and characterized by ﬂ ow cytometry. Following 24 h of CoCl 2 -induced hypoxic culture, the viability and metabolic activity of MSC were analyzed by trypan blue exclusion test and methyl thiazolyl tetrazolium (MTT) assay, respectively. The secretion of hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) was assessed in conditioned medium using enzyme-linked immunosorbent assay (ELISA) method. Results : Flow cytometry analysis showed > 99% of the population of MSCs cells were positive for CD73 and CD90 and > 62% were positive for CD105. While the cell viability of MSC was not affected by hypoxic cultured condition, the metabolic activity rate of these cells was decreased under hypoxic conditioning. In line with reduced metabolic activity, hypoxic human UC-derived MSC produced less HGF than normoxic counterpart. Compared to normoxic MSC, hypoxic preconditioned MSC secreted higher level of VEGF in the conditioned medium (p < 0.05). Conclusions : Hypoxia decreased the metabolic activity of MSCs associated with the modulation of HGF and VEGF secretions. It is suggested that hypoxia may also affect the therapeutic capacity of MSC cells.","PeriodicalId":51650,"journal":{"name":"BioMedicine-Taiwan","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45122123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Her sensorium gradually declined and became comatose. She was on Methotrexate, folic acid and prednisolone for her rheumatoid arthritis. The neurological examination and neuroimaging did not contribute in making the diagnosis. It is challenging to diagnose a metabolic cause of coma. Once diagnosis is established, the management becomes easier. On detailed investigation, she was found to have severe hypercalcemia with corrected serum calcium level being 18.2 mg%. Serum vitamin D level was also high, 150 ng/ml. On probing for detailed history, it was revealed that she had been taking a weekly dose of 60,000 IU of vitamin D for nearly 5 years. In recent times, association of various diseases has been reported with vitamin D deficiency. Vitamin D supplementation seems justified in this patient considering her age and the fact that she had rheumatoid arthritis; she was also taking corticosteroid. The recommended dose of vitamin D has been 400–800 IU/day. However, it is often prescribed at a dose of 60,000 IU/week, and sometimes patients self-medicate. There are no guidelines available for prescribing vitamin D at such a strength. Though safety of vitamin D has been established, vitamin D toxicity can occur sporadically with serious consequences. This was managed with intravenous fluids and diuretics. The patient also required subcutaneous calcitonin and low dose of corticosteroid, in addition to a session of haemodialysis for her hypercalcemia. The patient’s sensorium gradually improved as her calcium level returned to normalcy.","PeriodicalId":51650,"journal":{"name":"BioMedicine-Taiwan","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41320009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are hormone-dependent tumours, and estrogen will promote their development. It has been found that estrogen levels and cholesterol levels are inversely associated. Few studies have shown no relation between lipid profile and leiomyoma, but few studies suggested a positive correlation. The lipid profile of patients with uterine fibroids (the case group) and women without fibroids (the control group) is compared in the current study.\u0000 \u0000Materials and Methods: The case-control study included fifty subjects between 20 to 40 years. Twenty-five serum samples collected from women without evidence of leiomyoma were considered the control group. Twenty-five cases were admitted with various symptoms, diagnosed and confirmed as leiomyoma on histopathology.\u0000 \u0000Results: There was a substantial difference in Total Cholesterol (TC) and Low-Density Lipoprotein cholesterol (LDL-C) levels between patients with leiomyoma and healthy people. With a p-value of 0.04, the TC, LDL-C level in leiomyoma patients was substantially lower than that of healthy individuals in the general population. The levels of triglycerides, High-Density Lipoprotein cholesterol (HDL-C), and Very Low-Density Lipoprotein cholesterol (VLDL-C) were comparable across the case and control groups, though.\u0000 \u0000Conclusion: According to the study's findings, patients with leiomyoma have lower serum TC and LDL-C levels than healthy controls. This could be linked to patients with leiomyomas having higher estrogen levels. As a result, lipid profile variables like TC and LDL-C may be accurate indicators of leiomyoma. These findings point to the possibility of blood plasma lipid profiling for the non-invasive diagnosis of fibroids.","PeriodicalId":51650,"journal":{"name":"BioMedicine-Taiwan","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47560798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is quite challenging for the dentist since the oral hard and soft tissue structures show great variations in every patient. Conventional impression materials such as agar, alginate and elastomeric impression materials are used but these impression materials require patient’s cooperation during impression taking. These impression materials sometimes cause gagging, irritation and unpleasant taste and smell to the patient. To overcome these drawbacks digital impression and digital scanners are encouraging innovations. They increase the patient’s comfort and aids in the accuracy in recording tissue details. The development of new technology in the medical and dental fields is leading to advancements that enable physicians to create treatments and materials that can enhance patients' quality of life. Different IOSs have adopted varied scanning methodologies, which could result in different scanning accuracies. This was done to compare the accuracy of several IOSs and the effects of different variables on the accuracy result. Using 3D scanning technologies, a physical model which is digital three-dimensional computer-aided design (CAD) is transformed. For the design and production of specific parts using additive manufacturing (AM) technologies, this digital output offers several advantages. It is crucial to evaluate the dentistry industry's present level of 3D scanning technology utilization.","PeriodicalId":51650,"journal":{"name":"BioMedicine-Taiwan","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48209505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing ALP levels occurred from day 7 with the highest peak on day 14 post-stabilization. The purpose of this research was to analyze the effect of blue-LED exposure during the stabilization period on ALP levels in the tension side GCF of Wistar rats (Rattus norvegicus) at days 0, 3, 7, and 14 post-stabilizations.\u0000 \u0000Materials and Methods: Ten male Wistar rats aged 2.5-3 months, weighing 200-250 grams were divided into two groups (control and LED group).
