Abstract Arterial characterization of healthy descending thoracic aorta (DTA) is indispensable in determining stress distributions across wall thickness and different regions that may be responsible for aorta inhomogeneous dilation, rupture, and dissection when aneurysm occurs. Few studies have shown the inhomogeneity of DTA along the aorta tree considering changes in circumferential direction. The present study aims to clarify the circumferential regional characterization of DTA. Porcine DTA tissues were tested according to region and orientation using uniaxial tension. For axial test, results show that the difference in circumferential direction was mainly in collagen fiber modulus, where the… More >

Abstract Mechanical microenvironment can strongly affect the metastatic efficiency of circulating tumor cells. However, the effect of suspension state on their extravasation and the mechanisms involved are still unclear. To explore the influence of suspension state on extravasation (including adhesion, spreading and transendothelial migration) of breast tumor cells and its relevant molecular mechanism, MDA-MB-231 cells were cultured on poly (2-hydroxyethyl methacrylate) coated 6-well plates to minic the suspension state. Suspension state promoted adhesion, spreading and transendothelial migration of MDA-MB-231 cells to EAhy926 endothelial cells (ECs) monolayer under both the static condition and 0.5 dyne/cm² flow shear stress More >

Abstract Autophagy is an essential cellular homeostatic mechanism by which intracellular components are delivered into the lysosomes for degradation and recycling. Autophagy has been related with a diversity of pathological or physiological dentary processes such as bone remodeling, skeletal aging, osteoclastogenesis, osteoblastogenesis and different types of oral cancer. Platelet-rich plasma (PRP), isolated from autologous blood, is a plasma preparation containing a higher concentration of platelets which contains numerous different growth factors and cytokines that activate several cellular signaling cascades. The purpose of this study is to investigate the effect of PRP on autophagy stimulation in both More >

Abstract Many recent studies are concerned with low cost, easy to handle and alternative renewable energy as a feasible solution for the upcoming crisis of energy shortage. Microalgae are unicellular entities the can only depend on CO2, water and solar power to cover their nutritional needs. The current study is concerned with using algal cells in a polymeric hydrogel, as a cheap source of energy for electricity generation. Chlorella vulgaris has been proved to be a promising algal species for electricity generation, as compared with Micractinium reisseri. PVA hydrogel has been used for the immobilization of both algal… More >

Abstract Genomic instability and mutations caused by increases in oxidative stress during pregnancy can damage the fetoplacental unit and can upshot preterm birth. Oxidative damage to DNA may possibly be involved in etiology of preterm birth (PTB) which can be repaired by DNA repair gene. In the present study, we assessed the association of base excision repair gene family by analyzing the association of single nucleotide polymorphisms and genes expression in 8-oxoguanine glycosylase-1 (OGG1) and apurinic-apyrimidinic endonuclease 1 (APE1) genes with risk of preterm birth in Saudi women. We analyzed genotypes of four single nucleotide polymorphisms (SNPs) (rs1052133,… More >

Abstract ITS (Internal Transcription Spacer of nuclear ribosomal DNA) regions method was applied to identify and study the phylogenetic relationships existing between 41 individuals of Crocus, including 8 species collected in Iran (4 crop and 8 wild individuals) and 16 species (2 crop and 27 wild individuals) already registered in GenBank (NCBI). PCR amplifications were performed using the primer designed on the nucleotide sequence of nuclear region (ITS). A total of 12 sequences were obtained and registered in NCBI database. In particular, 4 of these sequences were not already present in the scientific library. Nucleotide… More >

Abstract Abiotic stresses, such as drought and salinity, adversely affect plant growth and productivity. Comparison between non transgenic and transgenic rice harboring CaMsrB2 gene, which induces tolerance to abiotic stress, is important to observe response of gene under abiotic stress. Phytohormone showed a tendency to increase under the drought stress or salinity stress in the transgenic plant. RT-PCR analysis showed that gene expression and phytohormone levels under abiotic stress, to be closely related. The CaMsrB2 gene is related to the expression of JA and ABA hormones. Therefore, the level of expression of these genes and hormones was More >

Abstract Sperm-associated antigen 9 (SPAG9) expression is increased in prostate tissues of prostate cancer patients. This experimental study aimed to investigate the role of SPAG9 in bone metastasis of prostate cancer. Immunohistochemical analysis showed that SPAG9 staining was positive in 81.67% of 240 cases of prostatic carcinoma but only in 6.67% of 120 cases of benign prostate hyperplasia. Strong PAG9 staining was positively correlated with Gleason score and bone metastasis in 240 prostate cancer patients (p < 0.05), but not with the age or serum prostatespecific antigen level (p > 0.05). PC-3 cells were transfected with shRNA… More >

Abstract This study aimed to investigate the role of high mobility group box-1 (HMGB1) expression in oral squamous cell carcinoma; HMGB1 promoted the proliferation and invasion of oral squamous cell carcinoma via activating epithelial-mesenchymal transformation (EMT). In this study, RNA transfection was used to silence the expression of HMGB1 in oral squamous cell carcinoma cells. CCK-8, cell clone formation and trans-well assays were used to detect the proliferation and invasion of cells before and after HMGB1 silencing. qRT-PCR and Western blot were used to detect changes in EMT marker protein expression before and after transfection.… More >

Abstract Cervical cancer (CC), has been identified as one of the most frequent malignant tumors all over the world, with high mortality in females. A growing number of investigations have confirmed that long noncoding RNAs (lncRNAs) play a crucial role in the progression of multiple cancers. Nonetheless, the biological function and regulatory mechanism of LINC01772 in CC haven’t been explored so far. In this study, LINC01772 expression was found to be upregulated in tissues and cells of CC. Knocking down LINC01772 suppressed CC cell proliferation, migration and epithelial-mesenchymal transition (EMT) process. Through molecular mechanism assays,… More >
