In vivo Evaluation of Cenderitide-Eluting Stent (CES) II.

The use of drug-eluting coronary stents has led to significant reduction in in-stent restenosis (ISR), but led to delayed endothelialization, necessitating the prolonged use of expensive anti-thrombotic drugs with their side-effects. Cenderitide (CD-NP) is a novel anti-proliferative chimeric peptide of semi-endothelial origin. Our previous work in vitro has demonstrated; that the smooth muscle cells were inhibited significantly more than endothelial cells which is the desirable feature of an anti-restenosis drug.

Role of epithelial-mesenchymal transition markers in triple-negative breast cancer.

Triple-negative breast cancers (TNBCs) are a heterogeneous group of breast tumours that are often associated with adverse pathological characteristics, poorer clinical outcomes and lack of targeted therapeutic options. Epithelial-mesenchymal transition, which plays a crucial role in tumour development and progression, is characterised by a transition from epithelial to mesenchymal phenotype and loss of proteins involved in maintaining cell junctions. We aimed to correlate protein expression of E-cadherin, Snail2 and transforming growth factor beta (TGF-β) with clinicopathological parameters and survivals of a series of patients with TNBC.

Pushing the envelope in tissue engineering: ex vivo production of thick vascularized cardiac extracellular matrix constructs.

Functional vascularization is a prerequisite for cardiac tissue engineering of constructs with physiological thicknesses. We previously reported the successful preservation of main vascular conduits in isolated thick acellular porcine cardiac ventricular ECM (pcECM). We now unveil this scaffold's potential in supporting human cardiomyocytes and promoting new blood vessel development ex vivo, providing long-term cell support in the construct bulk.

n-Type carbon nanotubes/silver telluride nanohybrid buckypaper with a high-thermoelectric figure of merit.

n-Type thermoelectric (TE) materials was made from carbon nanotube (CNT) buckypapers. We used silver telluride (Ag2Te) to achieve electron injection to the CNTs. The TE characterizations on more than 50 samples show that the CNTs/Ag2Te hybrids exhibit negative Seebeck coefficients (e.

A carbon monoxide gas sensor using oxygen plasma modified carbon nanotubes.

Carbon monoxide (CO) is a highly toxic gas that can be commonly found in many places. However, it is not easily detected by human olfaction due to its colorless and odorless nature. Therefore, highly sensitive sensors need to be developed for this purpose.
