In this paper, we’ve intend to carry out a deep spectral study on a series of red dyes such as: beet red; congo red; methyl red; neutral red; phenol red and carminic acid, to find out which are able to damage far ultraviolet rays by absorption. The experimental results have been carried out in our laboratory; it has shown that certain red pigments have an ability to absorb light in the far ultraviolet range due to their chemical structures. Therefore, they are able to dodging far ultraviolet rays. Moreover, the spectral analyzes by the emission of the series of red dyes studied, have showed that these red dyes emit beyond 600 nm.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134950035","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}

In the United States, the lifetime risk of developing an invasive form of breast cancer is 12.5% among women. BC arises in the lining cells (epithelium) of the ducts or lobules in the glandular tissue of the breast. The goal of the present study was to use machine learning (ML) as a novel technology to assess and compare the invasive forms of BC including, infiltrating ductal carcinoma, infiltrating lobular carcinoma, and mucinous carcinoma. To achieve this goal, we used ML algorithms and collected a dataset of 334 BC patients available at https://www.kaggle.com/amandam1/breastcancerdataset and interpreted this dataset based on the form of BC, age, sex, tumor stages, surgery type, and survival rate. Among the 334 patients, 70% were diagnosed with infiltrating ductal carcinoma, 27% with infiltrating lobular carcinoma, and 3% with mucinous carcinoma. Overall, out of 334 BC patients: 64 (19.16%) were in stage I, 189 (56.59%) in stage II, and 81 (24.25%) in stage III. Sixty-six, 67, 96, and 105 patients underwent lumpectomy, simple mastectomy, modified radical mastectomy, and other types of surgery, respectively. The survival rates were 83.4% for stage I, 79.1% for stage II, and 77% for stage III. Findings from the present study demonstrated that ML provides an important tool to curate large amount of BC data, as well as a scientific means to improve BC outcomes.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"11 1","pages":"980-984"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73600574","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}

Preeclampsia affects about 5-8% of pregnant women and it is a prevalent cause of maternal mortality. The level and composition of exosomes in the maternal circulation are altered in preeclampsia, and studies have shown that the major source of this greater level of exosomes is the placenta. We propose that exosomal contents from the placenta trigger maternal inflammation and vascular dysfunction, thereby exacerbating the disease progression. This mini-review will focus on the content of placental exosomes and how they could contribute to the development of preeclampsia.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86049972","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}

The explained variance of the models is 100% for the maximum temperature and 99.8 for the minimum with errors of 0.58 and 1.4ºC. You can estimate the graphs for the maximum temperature as for the minimum with the predicted values ​​and the errors that the model commits. The trend for the date of the maximum trend is negative while for the minimum it is positive. The records depend on the temperature returned in 1 month (LAG1T) and the temperature returned in 12 months (LAG12T), both for the maximum TX and for the minimum TN, as well as the station value.

Considering this we evaluated the employment of HeberFERON in patients with more than 14 days of viral shedding. Methods: This is a case series study of mild or moderate ill patients with laboratory-confirmed SARS-CoV-2 from one hospital in Havana, Cuba. We evaluated the effect and safety of HeberFERON in patients previously treated with Heberon Apha R that resulted with prolonged viral shedding. All patients received lopinavir-ritonavir 200/50 mg every 12 h and chloroquine 250 mg every 12 h. The primary endpoint was the time to negativization of viral RNA in patients with persistent viral shedding. The protocol was approved by the Ethics Committee of the Luis Diaz Soto Hospital. Results: The characteristics of the individuals included the age ranged from 19-87 years with a mean of 40 years, (Study and Control I groups), while in the Control group II the mean age was 43.8 years. Leukocytes, platelets, neutrophils, and eosinophils, show a significantly lower counts in the groups with viral persistence. Under IFN treatment the median viral shedding duration from diagnosis were 21 days and 19 days in Study group and Control group II, respectively. The Control group I showed a median viral shedding of 11 days (log-rank p = 0.000). Significant longer median viral negativization time (19 days) of symptomatic than asymptomatic patients (11 days, Long-rank p = 0.004), was observed. In patients under Heberon Alpha R treatment that resulted persistent for viral presence, the median time to viral negativization was 7 days for the period of administration of HeberFERON. Being symptomatic at diagnosis was significantly associated with viral persistence. The HeberFERON showed an adequate safety profile. Conclusion: HeberFERON showed a safe and rapid negativization of patients with viral persistence, achieving negativization in more than 50% of patients in 7 days.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84979893","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}

The dependency/independency of the f12 on Charge Balance (f0 = ChB) and other elemental and/or core balances fk = f(Yk) (k = 3,…,K) is the general criterion distinguishing between non-redox and redox systems. The f12 related to a redox system is the primary form of a Generalized Electron Balance (GEB), formulated for redox systems within the Generalized Approach to Electrolytic System (GATES) as GATES/GEB ⊂ GATES. The set of K balances f0,f12,f3,…,fK is necessary/ sufficient/needed to solve an electrolytic redox system, while the K-1 balances f0,f3,…,fK are the set applied to solve an electrolytic non-redox system. The identity (0 = 0) procedure of checking the linear independency/ dependency property of f12 within the set f0,f12,f3,…,fK (i) provides the criterion distinguishing between the redox and non-redox systems and (ii) specifies Oxidation Numbers (ONs) of elements in particular components of the system, and in the species formed in the system. Some chemical concepts, such as oxidant, reductant, oxidation number, equivalent mass, stoichiometry, perceived as derivative within GATES, are indicated. All the information is gained on the basis of the titration Ce(SO4)2 (C) + H2SO4 (C1) + CO2 (C2) ⇨ FeSO4 (C0) + H2SO4 (C01) + CO2 (C02), simulated with use of the iterative computer program MATLAB.","PeriodicalId":94067,"journal":{"name":"Journal of biomedical research & environmental sciences","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81920028","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}
