Cardioprotective effect of S-adenosyl L-methionine due to antioxidant and anti-inflammatory properties on isoproterenol-induced chronic heart failure in Wistar rats.

Objectives: The development and progression of chronic heart failure (CHF), hypertrophy, and remodeling strongly correlate with myocardial inflammation and oxidative stress. S-adenosylmethionine (SAMe), available as a dietary supplement, exerts anti-inflammatory and antioxidant effects. Previous reports show that by regulating angiogenesis and fibrosis, S-adenosyl-L-methionine improves ventricular remodeling.

ARID2 suppression promotes tumor progression and upregulates cytokeratin 8, 18 and β-4 integrin expression in TP53-mutated tobacco-related oral cancer and has prognostic implications.

Mutations in ARID2 and TP53 genes are found to be implicated in the tobacco related tumorigeneses. However, the effect of loss of ARID2 in the TP53 mutated background in tobacco related cancer including oral cancer has not been investigated yet. Hence, in this study we knockdown ARID2 using shRNA mediated knockdown strategy in TP53 mutated oral squamous cell carcinoma (OSCC) cell line and studied its tumorigenic role.

Synthesis, biological evaluation, and molecular docking analysis of phenstatin based indole linked chalcones as anticancer agents and tubulin polymerization inhibitors.

A library of new phenstatin based indole linked chalcone compounds (9a-z and 9aa-ad) were designed and synthesized. Of these, compound 9a with 1-methyl, 2- and 3-methoxy substituents in the aromatic ring was efficacious against the human oral cancer cell line SCC-29B, spheroids, and in a mouse xenograft model of oral cancer AW13516. Compound 9a exhibited anti-cancer activity through disrupting cellular integrity and affecting glucose metabolism-which is a hallmark of cancer.

Shape mediated splenotropic delivery of buparvaquone loaded solid lipid nanoparticles.

Buparvaquone (BPQ)-loaded asymmetric solid lipid nanoparticles (SLN) prepared by a modified nanoprecipitation method were evaluated for splenotropic drug delivery. BPQ SLN exhibited an average particle size of 650.28 ± 6.

Osteogenic Nanofibrous Coated Titanium Implant Results in Enhanced Osseointegration: Preliminary Study in a Rabbit Model.

A titanium implant surface when coated with biodegradable, highly porous, osteogenic nanofibrous coating has shown enhanced intrinsic osteoinductive and osteoconductive properties. This coating mimics extracellular matrix resulting in differentiation of stem cells present in the peri-implant niche to osteoblast and hence results in enhanced osseointegration of the implant. The osteogenic nanofibrous coating (ONFC) consists of poly-caprolactone, gelatin, nano-sized hydroxyapatite, dexamethasone, ascorbic acid and beta-glycerophosphate.

A coupled bimodal SPECT-CT imaging and brain kinetics studies of zolmitriptan-encapsulated nanostructured polymeric carriers.

The present investigation deals with preparation and characterization of anti-migraine zolmitriptan (ZMT) nanostructured polymeric carriers for nose to brain drug targeting. The drug-loaded colloidal nanocarriers of ZMT were prepared by modified ionic gelation of cationic chitosan with anionic sodium tripolyphosphate and characterized for particle size, zeta potential, and entrapment efficiency. Further, in order to investigate nose to brain drug targeting, biodistribution, and brain kinetics studies were performed using technetium radiolabeled nanocarriers (Tc-ZMTNP) in Swiss albino mice.

A polymeric temozolomide nanocomposite against orthotopic glioblastoma xenograft: tumor-specific homing directed by nestin.

The development of effective therapeutic strategies for glioblastoma faces challenges such as modulating the blood brain barrier (BBB) for drug influx and selectively targeting tumor cells. Nanocarrier drug delivery strategies are functionalized to enhance vascular permeability. We engineered superparamagnetic iron oxide nanoparticle (SPION) based polymeric nanocomposites (84.
