Biogenic synthesis of gold nanoparticles using dual extract of tulsi- for breast cancer tumor regression in mice.

This work aims to synthesize the gold nanoparticles (GNPs) using a dual extract of tulsi and (T+V-Gold) for breast cancer tumor regression. The GNPs were synthesized and characterized for their microscopic, spectroscopic and crystalline properties. Further, the GNPs were investigated for and studies for the treatment of the 4T1-induced triple-negative breast cancer murine model.

Bioengineered dual fluorescent carbon nano dots from Indian long pepper leaves for multifaceted environmental and health utilities.

In this article, we present the synthesis of Piper longum leaves-derived ethanolic carbon dots (PLECDs) using the most simplistic environmentally friendly solvothermal carbonization method. The PLECDs fluoresced pink color with maximum emission at 670 nm at 397 nm excitation. Additionally, the dried PLECDs dissolved in water showed green fluorescence with higher emission at 452 nm at 370 nm excitation.

Fabrication of white light emitting diodes via high yield surface passivated carbon quantum dots doped with terbium.

Exploiting the unique characteristics of various materials to create novel hybrid materials opens up innovative possibilities for cutting-edge applications across numerous fields. Here, we have synthesized novel surface functionalized photoluminescent carbon quantum dots (CQDs) doped with a rare-earth element (Tb) for white light emitting diodes. High quantum yield CQDs were produced utilizing leaves as a precursor using a one-step hydrothermal approach, and further, its optical characterization was thoroughly investigated.

Tinospora cordifolia Leaves Derived Carbon dots for Cancer Cell Bioimaging, Free radical Scavenging, and Fe Sensing Applications.

Herein, we report the fabrication of Tinospora cordifolia leaves-derived carbon dots (TCLCDs) from aqueous extract of leaves as carbon source via simple, environmentally friendly, hydrothermal carbonization (HTC) technique. The synthesized TCLCDs were characterized for their physicochemical properties and further explored for in-vitro cancer cell bioimaging, radical scavenging, and metal ion sensing. The synthesized TCLCDs showed excitation-dependent emission property with maximum emission at 435 nm under the excitation of 350 nm.

Carbon dots from an immunomodulatory plant for cancer cell imaging, free radical scavenging and metal sensing applications.

This work aimed to develop stem-derived carbon dots (TCSCD) for cancer cell imaging, free radical scavenging and metal sensing applications. The TCSCDs were synthesized by a simple, one-step, and ecofriendly hydrothermal carbonization method and characterized for their optical properties, morphology, hydrodynamic size, surface functionality, crystallinity, stability, bacterial biocompatibility, cellular imaging, free radical scavenging and metal sensing ability. The TCSCDs exhibited excellent biocompatibility with dose-dependent bioimaging results in melanoma (B16F10) and cervical cancer (SiHa) cell lines.

Antibiotics: their use and misuse in paediatric dentistry. A systematic review.

Aim: The use of antibiotics by health care professionals has benefitted humankind to a great extent. Recent reports show an increasing trend of antibiotic prescription by paediatric dentists. This systematic review aims to address the current pattern of antibiotics prescription among the paediatric dental population according to the evidence-based literature.

Protective effect of irbesartan, an angiotensin II receptor antagonist, alone and in combination with aspirin on middle cerebral artery occlusion model of focal cerebral ischemia in rats.

The present study was designed to test pretreatment multiple doses of irbesartan (IRB) 50 mg, aspirin (ASP) 100 mg and the combination of both drugs for 7 days on middle cerebral artery-occluded (MCAO) rats. Focal cerebral ischemia was induced by MCA occlusion for 2 hours followed by reperfusion for 22 hours. After 24 hours of ischemia, grip strength and locomotor activity tests were performed.
