{"title":"Age estimation using tooth cementum annulations: bias and sources of inaccuracy.","authors":"E. Gualdi-Russo, I. Saguto, P. Frisoni, M. Neri, J. Mongillo, N. Rinaldo","doi":"10.31083/j.fbl2705141","DOIUrl":"https://doi.org/10.31083/j.fbl2705141","url":null,"abstract":"BACKGROUND\u0000Counting the tooth cementum annulations (TCA) is a method for estimating the age at death of adults by sections of their tooth root. The objective of this study was to assess the precision of counting the cementum incremental lines and the congruence between known age and age estimates. Possible factors affecting the accuracy of the estimate were also analyzed.\u0000\u0000\u0000METHODS\u0000A sample of 67 permanent teeth extracted from individuals with known age (18-84 years) and sex was analyzed to calculate the dental age.\u0000\u0000\u0000RESULTS\u0000Results demonstrate an excellent inter- and intra-observer reliability of annuli counting, with dissimilarities within the limits of agreement. A moderate positive correlation was found between chronological age and TCA. Our results showed that age congruence rates differed across age groups (85% congruence in individuals ≤30 years; 75% in individuals aged 31-60 years; 60% in the over 60s). Considering the bias, this method showed a clear tendency to underestimate age in specimens from old people. After age 43, the TCA estimate is highly inaccurate exceeding the underestimation of 10 years, on average, in comparison to the chronological age. Both chronological age and dental arch seem to influence the accuracy of estimates, unlike sex and the tooth root number.\u0000\u0000\u0000CONCLUSIONS\u0000TCA analysis is characterized by high precision and low accuracy, decreasing with age. Therefore, its applicability is limited in elderly subjects. The choice of methods for age estimation in adult skeletal remains should take into account the particular age range of individuals. We recommend using different age estimation methods to verify the reliability of the performed assessments.","PeriodicalId":50430,"journal":{"name":"Frontiers in Bioscience-Landmark","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75191543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, BRS Xiquexique increased the crypt goblet diameter and the crypt depth compared to all treatments and controls.

All patients complied with at least three consecutive monthly intravitreal treatments and final follow-up visit at 12 months after the initial anti-VEGF treatment of aflibercept or ranibizumab. Using optical coherence tomography angiography (OCTA), the central macular thickness (CMT), microvascular density in the superficial capillary plexus (SCP), deep capillary plexus (DCP), choroidal neovascularization (CNV) lesions, as well as subretinal fibrotic lesions were compared between baseline and final visit.\u0000\u0000\u0000RESULTS\u0000The mean number for anti-VEGF injections was 4.40 ± 0.88 during the 12 months of follow-up. There was no significant difference in best-corrected visual acuity (BCVA) and vascular density in SCP and DCP (p > 0.05) between baseline and final follow-up. The CMT decreased from 434.95 ± 87.62 μm at baseline to 365.15 ± 78.92 μm at final visit (p = 0.02). Compared with the baseline, the fine vessels, such as capillary tufts, regressed and the relative density of CNV lesion decreased by 19.12% (p = 0.01), while the relative density of the subretinal fibrosis increased approximately 1.21-fold (p = 0.03) at the final follow-up.\u0000\u0000\u0000CONCLUSIONS\u0000The progression of neovascular remodeling and subretinal fibrosis may serve as biomarkers to predict incomplete response to anti-VEGF therapy in patients with NVAMD.

Therefore, there is an urgent need to develop new and effective treatment strategies. Recent evidence has shown that metabolic processes and cell behaviors in ovarian cancer are regulated by intracellular factors as well as metabolites in the tumor microenvironment (TME), which determine occurrence, proliferation, and metastasis. In this review, we describe the comprehensive landscape of metabolic cross-talk between ovarian cancer and its TME with a focus on the following four aspects: (1) intracellular metabolism based on the Warburg effect, (2) metabolism in non-tumor cells in the ovarian TME, (3) metabolic communication between tumor cells and non-tumor cells in the TME, and (4) metabolism-related therapeutic targets and agents for ovarian cancer. The metabolic cross-talk between ovarian cancer and its microenvironment involves a complex network of interactions, and interrupting these interactions by metabolic interventions is a promising therapeutic strategy.","PeriodicalId":50430,"journal":{"name":"Frontiers in Bioscience-Landmark","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87533450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Senescent cells that surround cancer tissues reduce the effects of various cancer treatments and induce cancer recurrence through senescence-associated secretory phenotype (SASP) secretion. Thus, for good therapeutic effect, candidate drugs should be selective for both cancer and senescent cells. In this study, we investigated the selective effect of piperine as a potential senostatic agent as well as an anticancer drug.\u0000\u0000\u0000METHODS\u0000The effect of piperine on cytotoxicity and cell proliferation was tested by lactate dehydrogenase (LDH) or water-soluble tetrazolium salt (WST) assay. The levels of p16INK4a and p21, mitogen-activated protein kinases (MAPKs), and mammalian target of rapamycin (mTOR) were analyzed by Western blot analysis. The rejuvenation effects of piperine on the senescent cells were investigated by senescence-associated beta-galactosidase (SA-β-Gal) stain, mitochondria membrane potential (MMP) and reactive oxygen species (ROS) levels, and senescence-associated secretory phenotype (SASP) secretion after treatment with piperine in senescent cells.\u0000\u0000\u0000RESULTS\u0000While piperine induced high cytotoxicity in various cancer cell lines, it led to proliferating of premature senescent cells similar with nicotinamide (NA), which is known as a rejuvenating drug of senescent cells.
