A subset of benign (WHO grade I) skull base meningiomas show early progression/recurrence (P/R) in the first years after surgical resection. Besides, complete surgical resection may be difficult to achieve safely in skull base meningiomas due to complex neurovascular structures. The one main challenge in the treatment of skull base meningiomas is to determine factors that correlate with P/R. We retrospectively investigated the preoperative CT and MR imaging features for the prediction of P/R in skull base meningiomas, with emphasis on quantitative ADC values...

Nephrolithiasis is a common urological disease with high prevalence and recurrence rates. Characterizing gut microbiome profiles of nephrolithiasis patients may provide valuable insights and potential biomarkers for the disease. Therefore, we explored the relation between gut microbiome and nephrolithiasis using 16S ribosomal RNA (rRNA) gene sequencing. 13 patients with multiple kidney stones and 13 matched healthy controls were recruited. A decreasing trend in number of observed species in nephrolithiasis patients was detected, although statistical significance was not reached (p = 0...

PURPOSE: To review the empirical evidence to support the conventional (sequential) model of breast cancer progression, which is based on the paradigm that cancer passes through several stages, including an in situ stage prior to an invasive stage, and thereafter (in some cases) disseminates to the lymph nodes and distant organs. METHODS: We review the cancer literature of the last 50 years which relates to the prevention of invasive breast cancer (through radiotherapy or surgery) and reductions in the mortality for breast cancer...

BACKGROUND CXC chemokine ligand 16 (CXCL16) is a soluble chemokine with a transmembrane domain, playing an important role in inflammatory regulation. NF-κB has a critical role in tumor progression. Recent studies focused on the effect of CXCL16 on tumor progression. However, few reports showed the influence of CXCL16 on lung cancer, especially in regulating NF-κB activity. Here we investigated CXCL16 expression and its clinical significance in lung cancer, as well as the effect on lung cancer cell biological characteristics by regulating NF-κB...

Variable selection plays a key role in classification and multivariate calibration. Variable selection methods are aimed at choosing a set of variables, from a large pool of available predictors, relevant to the analyte concentrations estimation, or to achieve better classification results. Many variable selection techniques have now been introduced among which, those which are based on the methodologies of swarm intelligence optimization have been more respected during a few last decades since they are mainly inspired by nature...

Although prostate cancer can be surgical excised and effectively treated by androgen-deprivation therapy, radiotherapy, or chemotherapy, management of patients with advanced or drug-resistance prostate cancer stills remains a big trouble. Accumulated evidence indicated that miR-182 and Wnt/β-catenin function as tumor oncogene in the progression of a variety of tumors. However, little is known about how miR-182 regulates β-catenin signal molecular and impacts on the tumorigenesis of human prostate cancer. In this study, employing the analyses of qRT-PCR, we found that prostate cancer tissues expressed much more miR-182 than non-cancer tissues did...

Liver is the heaviest internal organ of the human body and performs many vital functions. Prolonged cirrhosis and fatty liver disease may lead to the formation of benign or malignant lesions in this organ, and an early and reliable evaluation of these conditions can improve treatment outcomes. Ultrasound imaging is a safe, non-invasive, and cost-effective way of diagnosing liver lesions. However, this technique has limited performance in determining the nature of the lesions. This study initiates a computer-aided diagnosis (CAD) system to aid radiologists in an objective and more reliable interpretation of ultrasound images of liver lesions...

The tumor microenvironment (TME) governs all aspects of cancer progression and in vitro 3D cell culture platforms are increasingly developed to emulate the interactions between components of the stromal tissues and cancer cells. However, conventional cell culture platforms are inadequate in recapitulating the TME, which has complex compositions and dynamically changing matrix mechanics. In this study, we developed a dynamic gelatin-hyaluronic acid hybrid hydrogel system through integrating modular thiol-norbornene photopolymerization and enzyme-triggered on-demand matrix stiffening...

Presently, developing effective anti-colon cancer drugs still remains to be important. Ginkgolic acids (GA), as a botanical drug extracted from the seed coat of Ginkgo biloba L., possess various bioactive properties. Our findings, for the first time, indicated that GA suppressed colon cancer cell proliferation, migration and invasion. GA led to cell death through G0/G1 phase arrest. In addition, apoptosis was significantly induced by GA treatment. The intrinsic apoptosis pathway was included, proved by the release of cytochrome c (Cyto-c) from the mitochondria into the cytosol...

INTRODUCTION: The diaphragmatic response to increased mechanical load following withdrawal of mechanical ventilation (MV) is critical in determining the outcome of extubation. Using ultrasonography, we aimed to evaluate the performance of excursion-time (E-T) index- a product of diaphragm excursion and inspiratory time, to predict the outcome of extubation. METHODS: Right hemidiaphragm excursion, inspiratory time (Ti) and E-T index were measured using ultrasonography during MV: (1) On assist control mode (A/C) during consistent patient triggered ventilation (2) Following 30 minutes during a spontaneous breathing trial (SBT) (3) Between 4-24 hours following extubation...

Endometrial cancer (EC) is one of the most common malignancies in women worldwide. EC is linked to chronic exposure to estrogens that is unopposed by protective effects of progesterone. Progesterone modulates gene expression via classical nuclear receptors, and has rapid effects via the less characterized membrane-bound progesterone receptors (mPRs) of the progestin and adipoQ receptor (PAQR) family. The presence of mPRs in EC has not been investigated to date. The aims of this study were to examine PAQR7, PAQR8 and PAQR5, which encode for mPRα, mPRβ and mPRγ, respectively, for their expression and localization in EC tissue and adjacent control endometrium...

Type I crustins are crucial effectors of crustacean immune system. Various type I crustins with high sequence diversity possess different antimicrobial activities. To date, the mechanism on how the sequence diversity of type I crustins affects their antimicrobial activities is largely unclear, and how different crustins function together against bacterial invasion still remains unknown. In this study, we identified two novel type I crustins, namely, SpCrus3 and SpCrus4, from an economically important crab, Scylla paramamosain...
