Murraya paniculata (MP) can be used as a reducing agent to produce silver nanoparticles (AgNPs) using a simple procedure. AgNPs are characterized in morphological and chemical properties, antioxidant activity, and cytotoxicity. The morphology of AgNPs derived from MP shows a face-centered cubic structure, spherical shape with an average particle size of 23 nm. The chemical structure shows characteristic peaks of AgNPs using UV-vis spectrometer at 438 nm. The formation of AgNPs is confirmed by analyzing their vibrational states under infrared radiation; typical peaks of AgNPs are recognized: at 3429 cm−1 (O-H stretch, H-bonded alcohols, phenols groups), 2923 cm−1 (C-H stretch alkanes), 1626 cm−1 (N-H bend 1° amines), 1583 cm−1 (C-C stretch in ring aromatic), 1039 cm−1 (C-N stretch aliphatic amines), 728 cm−1 (C-Cl stretch alkyl halides), and 589 cm−1 (C-Br stretch alkyl halides), respectively. AgNPs produced from MP show antioxidant activity and cytotoxicity. They show the highest sensitivity toward Bacillus cereus. Cytotoxicity of biosynthesized AgNPs, determined by scratch wound assay on in vitro human endothelial vein cell, created from MP showed dose-dependent activity. These AgNPs, at a concentration of 15.625 μg/mL, stimulate the proliferation and migration of endothelial cells (EC) showing an angiogenic activity.
An automatic pesticide mixing and water level control of irrigation system powered by solar, using PLC and nrf24l01 module is focussed. The proposed system consist of pesticide mixer which automatically mixes the pesticide and water in particular ratio and the mixer is automatically sprayed to the field on the programmed date with the help of PLC. This system will also be useful in monitoring the soil moisture condition and level of the water in the field via moisture sensors and ultrasonic sensor which is connected in the transmitter side of the RF module. The system proposes a soil moisture sensor and ultrasonic sensor at each place in the field where the moisture content of the soil and water level in the field has to be monitored which is powered by solar. When moisture content in the soil is low or water level in the field is below certain level, the transmitter RF sends a signal to the receiver RF and accordingly the motor is turned ON/OFF with the help of PLC.
Over the past decade, there has been a progressive evolution of cardiac marker testing in patients with acute coronary syndromes. Myocardial infarction (MI) is the leading cause of death in the developed world. Biomarkers have an vital role in analysis, risk stratification, administrative running and medical assessment making in the setting of patients presenting with signs and symptoms of MI. Cardiac troponin (cTn) rose to prominence during the 1990s and has evolved to be the cornerstone for diagnosis of MI. Cardiac troponins are released from myocytes following myocardial damage and loss of membrane integrity. Troponin T are member of a group of cardiac regulatory proteins which function to regulate the calcium mediated interaction of muscle filaments actin and myosin resulting in contraction and relaxation of striated muscle. New algorithms integrating Brain natriuretic peptide (BNP), NT-proBNP, and more sensitive cTn assays footing potential for more rapid diagnosis of MI, allowing for appropriate management steps to be initiated and more efficient and effective utilization of healthcare resources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
