BACKGROUND: It has been reported that miR-203 expression was aberrant in various types of cancers, and it could be used as a prognostic biomarker. Therefore, in this study, we aimed to evaluate the prognostic value of miR-203 expression in solid tumors by using meta-analysis and The Cancer Genome Atlas (TCGA) datasets. METHODS: By doing a literature research in PubMed, Embase and the Cochrane Library (last update by December 2016), we were able to identify the studies assessing the prognostic role of miR-203 in various tumors...

Microbial fuel cell-coupled constructed wetlands (CW-MFCs) use electrochemical, biological, and ecological functions to treat wastewater. However, few studies have investigated the risks of antibiotic resistance genes (ARGs) when using such systems to remove antibiotics. Therefore, three CW-MFCs were designed to assess the dynamics of ARGs in filler biofilm and effluent over 5000 h of operation. The experimental results indicated that relatively high steady voltages of 605.8 mV, 613.7 mV, and 541.4 mV were obtained at total influent antibiotic concentrations of 400, 1,000, and 1600 μg L(-1), respectively...

BACKGROUND: In recent years, labiaplasty has jumped in popularity, despite opposition to the procedure. In 2007, the American College of Obstetricians and Gynecologists declared the recommendation of cosmetic vaginal procedures to be "untenable," although in 2016 they allowed consideration of labiaplasty in adolescents if symptoms persist. The reasons for labiaplasty requests are not yet fully understood, and physician opposition limits patient access to surgical relief. METHODS: In this prospective study, 50 consecutive patients consulting about labiaplasty were given a questionnaire assessing 11 physical and appearance-related symptoms associated with elongated labia...

Higher expression of growth differentiation factor-9 (GDF-9) in keloids compared with hypertrophic scars and normal skin tissues has been reported recently. The present study was performed to investigate the role of GDF-9 in keloid pathogenesis, and to elucidate its implication for asiaticoside in the keloid management. The data showed that GDF-9 could enhance the proliferation, migration, and invasion of keloid fibroblasts (KFs), while it only slightly elevated collagen expression, indicating that the effect of GDF-9 was opposite to that of TGF-β1...

NUBPL is an assembly factor for human mitochondrial complex I, which is the biggest member of mitochondrial respiratory chain. However, the relationship between NUBPL and carcinoma progression remains unknown. In this study, NUBPL was characterized for its role in colorectal cancer (CRC) and the underlying molecular mechanisms. Data (n=197) from Oncomine database revealed that mRNA levels of NUBPL were remarkably overexpressed in CRC tissues compared with normal tissues. In addition, immunohistochemical analysis of 75 pairs of CRC and nontumorous tissues demonstrated that expression level of NUBPL was significantly higher in CRC tissues, and its expression level was positively associated with lymph node metastasis (P=0...

Undernutrition during pregnancy has been associated to increased vulnerability to develop metabolic and behavior alterations later in life. The endocannabinoid system might play an important role in these processes. Therefore, we investigated the effects of a moderate maternal calorie-restricted diet on the levels of the endocannabinoid 2-arachidonoyl glycerol (2-AG), arachidonic acid (AA) and the N-acylethanolamines (NAEs) anandamide (AEA), oleoylethanolamide (OEA) and palmitoylethanolamide (PEA) in the brain of newborn rat offspring...

The 22q11.2 deletion syndrome (22q11.2DS; velo-cardio-facial syndrome; DiGeorge syndrome) is a congenital anomaly disorder in which haploinsufficiency of TBX1, encoding a T-box transcription factor, is the major candidate for cardiac outflow tract (OFT) malformations. Inactivation of Tbx1 in the anterior heart field (AHF) mesoderm in the mouse results in premature expression of pro-differentiation genes and a persistent truncus arteriosus (PTA) in which septation does not form between the aorta and pulmonary trunk...

During embryonic development, mechanical forces are essential for cellular rearrangements driving tissue morphogenesis. Here, we show that in the early zebrafish embryo, friction forces are generated at the interface between anterior axial mesoderm (prechordal plate, ppl) progenitors migrating towards the animal pole and neurectoderm progenitors moving in the opposite direction towards the vegetal pole of the embryo. These friction forces lead to global rearrangement of cells within the neurectoderm and determine the position of the neural anlage...

#11
Harriet Dempsey-Jones, Ada Kritikos
Previous research suggests integration of visual and somatosensory inputs is enhanced within reaching (peripersonal) space. In such experiments, somatosensory inputs are presented on the body while visual inputs are moved relatively closer to, or further from the body. It is unclear, therefore, whether enhanced integration in "peripersonal space" is truly due to proximity of visual inputs to the body space, or, simply the distance between the inputs (which also affects integration). Using a modified induction of the rubber hand illusion, here we measured proprioceptive drift as an index of visuosomatosensory integration when distance between the two inputs was constrained, and absolute distance from the body was varied...

Predictability may be an important component of cooperative action, or it may arise as a by-product of involuntary entrainment with another's behavior. Further, differences previously observed in cooperative versus competitive actions may represent a fundamental distinction between behaviors with opposite goals, or they may simply reflect the output of different physical actions. The role of predictability in cooperative versus competitive behavior was directly tested using a joint sequential button-pressing task in which Participant 1 (P1) pressed a key followed by P2 pressing a key...

Heterolytic cleavage of homoatomic bonds is a challenge, as it requires separation of opposite charges. Even highly strained homoatomic rings (e.g., cyclopropane and cyclobutane) are kinetically stable and do not react with nucleophiles or electrophiles. In contrast, cycloalkanes bearing electron-donating/withdrawing substituents on adjacent carbons have polarized C-C bonds and undergo numerous heterolytic ring-opening and expansion reactions. Here we show that upon electrophile activation phosphorus homocycles exhibit analogous reactivity, which is modulated by the amount of ring strain and extent of bond polarization...

Tooth development is initiated by epithelial-mesenchymal interactions via basement membrane (BM) and growth factors. In the present study, we found that nephronectin (Npnt), a component of the BM, is highly expressed in the developing tooth. Npnt localizes in the BM on the buccal side of the tooth germ and shows an expression pattern opposite that of the dental epithelial stem cell marker Sox2. To identify the roles of Npnt during tooth development, we performed knockdown and overexpression experiments using ex vivo organ and dental epithelial cell cultures...

Curcumin is a natural agent that has ability to dampen tumor cells' growth. However, the natural form of curcumin is prone to degrade and unstable in vitro. Here, we demonstrated that demethoxycurcumin (a curcumin-related demethoxy compound) could inhibit cell proliferation and induce apoptosis of ovarian cancer cells. Moreover, IRS2/PI3K/Akt axis was inactivated in cells treated with demethoxycurcumin. Quantitative real-time reverse transcription polymerase chain reaction demonstrated that miR-551a was down-regulated in ovarian cancer tissues and ovarian cancer cell lines...

Bulimia nervosa (BN) and binge eating disorder (BED) have been associated with poorer reward-related inhibitory control, reflected by a reduced tendency to delay gratification. The opposite has been reported in anorexia nervosa (AN), but differences have not been directly compared across eating disorders (EDs). This study investigated self-reported (Delaying Gratification Inventory) and task-based (temporal discounting) inhibitory control in 66 women with an ED and 28 healthy controls (HCs). Poorer task-based inhibitory control was observed in the BN compared with the AN group and poorer self-reported inhibitory control in the BN and in the BED groups compared with the AN and the HC groups, suggesting that reward-related inhibitory control varies across EDs...

Surface nanodroplets are important units for lab-on-a-chip devices, compartmentalised catalytic reactions, high-resolution near-field imaging, and many others. Solvent exchange is a simple solution-based bottom-up approach for producing surface nanodroplets by displacing a good solvent of the droplet liquid by a poor one in a narrow channel in the laminar regime. The droplet size is controlled by the solution composition and the flow conditions during the solvent exchange. In this paper, we investigated the effects of local microfluidic structures on the formation of surface nanodroplets...

An unusual temperature-dependent autoinductive reversal of enantioselectivity (TARE) was discovered in an asymmetric palladium-mediated [3+3]-annulation of 4-hydroxycoumarin with Morita-Baylis-Hillman acetate. The absolute stereochemistry of the reaction product can be readily inversed by solely modifying the reaction temperature (from 10 °C to 60 °C), affording multicyclic adducts with the opposite configurations respectively in moderate to excellent enantiopurities. Furthermore, the first reported example of palladium-mediated bidirectional asymmetric autoinduction was identified to mainly contribute to the reversal of enantioselectivity, in which the corresponding adduct actively participated in the stereocontrol during the reaction...
