Urinary bladder cancer is the fifth most common cancer in the Western world. Increasing evidence has shown that DNA methylation in bladder cancer is expansive and is implicated in pathogenesis. Furthermore, distinct methylation patterns have been identified between non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), as well as ...

Constitutional mismatch repair deficiency (CMMR-D) due to biallelic germline mutations in one of four mismatch repair genes causes a childhood cancer syndrome characterized by a broad tumor spectrum including hematological malignancies, and brain and Lynch syndrome-associated tumors. Herein, we report three children who had in addition to CMMR-D-associated malignancies multiple ...

Fire blight, incited by the enterobacterium Erwinia amylovora, is a destructive disease of Rosaceae, particularly of apples and pears. There are reports on the molecular mechanisms underlying E. amylovora pathogenesis and how the host activates its resistance mechanism. The host's resistance mechanism is quantitatively controlled, although some major genes might ...

BACKGROUND: Basal cell carcinoma (BCC) is the most common malignancy in Caucasians. It is an important driver of health care costs and causes significant morbidity. Topical imiquimod is a good non-invasive treatment alternative for surgical excision in superficial BCC (sBCC). However, there are currently no uniform histological definitions of sBCC. ...

Arbuscular mycorrhiza (AM) fungi form nutrient-acquiring symbioses with the majority of higher plants. Nutrient exchange occurs via arbuscules, highly branched hyphal structures that are formed within root cortical cells. With a view to identify host genes involved in AM development, we isolated Lotus japonicus AM-defective mutants via a microscopic screen ...

It was found for the first time that single tail ionic liquid (IL) surfactants, 1-alkyl-3-methylimidazolium bromides [Cnmim]Br (n = 10, 12, 14), form unilamellar vesicles in aqueous solutions without any additives. With the increase in IL concentrations, the self-assembly of these ILs can transfer from spherical micelles to rodlike micelles ...

The scope of the asymmetric silyl transfer to unsaturated lactones utilising a C2-symmetric NHC-Cu(i) catalyst has been established and kinetic resolutions mediated by silyl transfer have been used to prepare enantiomerically enriched anti-4,5-disubstituted 5-membered lactones. The method has been exploited in an expedient synthesis of (+)-blastmycinone.

A simple and novel microRNA (miRNA) biosensor was developed using DNA-Au bio bar code (DNA-Au) and G-quadruplex-based DNAenzyme. DNA-Au increased the amount of miRNA-21 participating in hybridization. Hemin/G-quadruplex DNAenzyme significantly improved the catalysis of H2O2 by oxidation of hydroquinone, resulting in an obvious reduction current of benzoquinone for miRNA-21 indirect ...

Emerging data indicate that growth hormone (GH) therapy could have a role in improving cognitive function. GH replacement therapy in experimental animals and human patients counteracts the dysfunction of many behaviours related to the central nervous system (CNS). Various behaviours, such as cognitive behaviours related to learning and memory, are ...

The benefits of adjuvant whole-breast irradiation (WBI) after breast-conserving surgery are well established and WBI is a standard of care. In selected patients with early stage breast cancer, accelerated partial breast irradiation (APBI) has emerged as an alternative treatment option to WBI. Early trials of APBI have demonstrated an excellent ...

Ecologically mediated selection has increasingly become recognised as an important driver of speciation. The correlation between neutral genetic differentiation and environmental or phenotypic divergence among populations, to which we collectively refer to as isolation-by-ecology (IBE), is an indicator of ecological speciation. In a meta-analysis framework, we determined the strength and ...

ABSTRACT Injection of carbon dioxide in deep saline aquifers is considered as a method of carbon sequestration. The efficiency of this process is dependent on the fluid-fluid and rock-fluid interactions inside the porous media. For instance, the final storage capacity and total amount of capillary-trapped CO2 inside an aquifer are ...

Chloroethenes like trichloroethene (TCE) are prevalent environmental contaminants, which may be degraded through reductive dechlorination. Chemical models such as cobalamine (vitamin B12) and its simplified analogue cobaloxime have served to mimic microbial reductive dechlorination. To test whether in vitro and in vivo mechanisms agree, we combined carbon and chlorine isotope ...

Cytokines and chemokines represent two important groups of proteins that control the immune system. Dysregulation of the network in which these immunomodulators function can result in uncontrolled inflammation leading to various diseases, including rheumatoid arthritis, characterized by chronic inflammation and bone erosion. Chemokine activity is regulated at multiple levels, such ...

(-)-Kaitocephalin has been synthesized. With the C9 stereocenter from Garner's aldehyde, the C4 quaternary carbon was installed by the desymmetrization of the Cbz-protected serinol. The remaining stereogenic centers were generated through mercuriocyclization, epoxidation and regioselective epoxide opening, in which the quaternary carbon most likely played crucial roles in the stereoinduction.
