Reference hematologic and biochemical parameters must be established to evaluate healthy cynomolgus monkeys and investigate drug safety in non-clinical research. In the present study, data from 4,834 healthy cynomolgus monkeys were used to establish a reference for various age groups.Methods: A total of 4834 healthy cynomolgus monkeys (649 males and 4185 females) were selected and divided into six groups according to age and sex. Twenty hematological parameters and 17 serum biochemical parameters were detected, and the effects of age and sex were analyzed.Results: A reference database of hematological and biochemical parameters was established according to age (six groups) and sex (male and female). Significant differences were observed in White blood cell, Red blood cell, Hemoglobin, Hematocrit, Total protein, Albumin, Total bilirubin, Direct bilirubin, Alkaline phosphatase, Glucose, Blood urea nitrogen, Creatinine, Calcium, Total cholesterol, Triglyceride, and Lactate dehydrogenase values according to age in the juvenile and young groups (P<0.05).

Growing evidence supports a key role of the tumor microenvironment in the growth, progression, and metastasis of OV. However, the prognostic effects of gene expression signatures associated with the OV microenvironment have not been well established. This study was aimed at applying the Estimation of STromal and Immune cells in MAlignant Tumor tissues using Expression data (ESTIMATE) algorithm to identify tumor-microenvironment-associated genes that predict outcomes in patients with OV.Methods: The gene expression profiles of OV samples were downloaded from The Cancer Genome Atlas database. The immune and stromal scores of 469 OV samples on the basis of the ESTIMATE algorithm were available. To better understand the effects of gene expression signatures associated with the OV microenvironment on prognosis, we categorized these samples into groups with high and low ESTIMATE scores. A different OV cohort from the Gene Expression Omnibus (GEO) database and immunohistochemistry from The Human Protein Atlas database were used for external validation.Results: The molecular subtypes of patients with OV correlated with the stromal scores, and the mesenchymal subtype had the highest stromal scores. Patients with higher stromal scores had lower 5-year overall survival; 449 differentially expressed genes in the stromal score group were identified, 26 of which were significantly associated with poor prognosis in patients with OV (p < 0.05). In another OV cohort from the Gene Expression Omnibus database, six genes were further validated to be significantly associated with poor prognosis. Immunohistochemistry data from The Human Protein Atlas database confirmed the overexpression of CX3CR1, GFPT2, NBL1, TFPI2, and ZFP36 in OV tissues compared with normal tissues.Conclusion: Our findings suggest that CX3CR1, GFPT2, NBL1, TFPI2, and ZFP36 may be promising biomarkers for OV prognosis, with clinical implications for therapeutic strategies.\u0000","PeriodicalId":431549,"journal":{"name":"BIO Integration","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116068141","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 contrast-enhanced ultrasound showed a “fast-in and fast-out” mode; after subsidence, a “fence-like” change was observed, and the enhancement range was significantly greater than the range of two-dimensional ultrasound. In MRI, T1WI showed a low signal or isosignal; T2WI showed a high signal; DWI showed a high signal and low ADC value; and most of the enhanced MRI showed inhomogeneous hyperenhancement.Conclusion: Conventional ultrasound, contrast-enhanced ultrasound and MRI are complementary methods that provide additional imaging information for the diagnosis of cervical large-cell neuroendocrine carcinoma.\u0000","PeriodicalId":431549,"journal":{"name":"BIO Integration","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131171816","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}

Sixty new patients with papillary thyroid carcinoma (PTC) were evaluated with the MLP neural network model. The metastasis status of these patients was then compared with the pathological results. The prediction of metastasis by the MLP and by multiple regression was compared.Results: Calcification, age, sex, and maximum diameter were important predictive factors of CLNM by the MLP, and the area under the receiver operating characteristic curve was 0.715. No significant differences were found between the MLP and multiple regression in predicting CLNM.

Tumor-associated macrophages (TAMs) in the tumor microenvironment are associated with distant metastasis as well as poorer outcomes in breast cancer. Therefore, monitoring TAMs may guide prognostic assessment. This study explores an imaging modality based on a two-step click chemistry procedure for detecting TAMs in breast cancer. Mannose-targeted liposomes (MAN-lipo-AAG) and non-targeted liposomes (lipo-AAG) encapsulating Ac4GalNAz were prepared and comprehensively characterized. The sizes of the prepared MAN-lipo-AAG and lipo-AAG were 126 ± 0.22 and 93 ± 0.23 nm, respectively. In vitro studies demonstrated higher uptake of MAN-lipo-AAG than lipo-AAG by RAW264.7 cells. Moreover, flow cytometry and confocal microscopy confirmed that bright, homogeneous fluorescence labeling was present on RAW264.7 cell membranes in the MAN-lipo-AAG group. Furthermore, in vivo analysis indicated that MAN-lipo-AAG, compared with lipo-AAG, had higher accumulation in a 4T1 xenograft model and higher uptake by mannose-overexpressing TAMs. This study describes a promising approach for specific and non-invasive TAM-targeted imaging via metabolic glycoengineering.\u0000","PeriodicalId":431549,"journal":{"name":"BIO Integration","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133488461","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}
