In recent decades, several scientists focused their process towards nanoparticles synthesis by using various sustainable approaches. Cocos nucifera (C. nucifera) was one of the versatile trees in tropical regions which also can act as a thrust quencher in all over the world. Cocos nucifera coir was one of the waste by-products in all coconut-refining industries and with the help C. nucifera coir, Palladium nanoparticles (Pd NPs) were synthesized. Green-synthesized spherical-shape Pd NPs were over layered by secondary metabolites from C...

Heat shock proteins (HSPs) are immunogenic, ubiquitous class of molecular chaperones, which are induced in response to various environmental and microbial stressful conditions. It plays a vital role in maintaining cellular protein homeostasis in eukaryotic cells. In this study, we described a comprehensive comparative data by bioinformatics approach on three different full length cDNA sequences of HSP family at molecular level. The cDNA sequences of three HSPs were identified from constructed cDNA library of Channa striatus and named as CsCPN60, CsHSP60 and CsHSP70...

This study deals with a new and efficient metal-free regioselective synthesis of pyrimido-fused indazoles with nitrogen ring junction motifs. We have developed a metal-free domino type reaction between 3-aminoindazole, aryl aldehydes and aceotophenones in the presence of KOH/DMF that leads to pyrimido[1,2-b]indazole analogues. Response Surface Methodology (RSM) coupled with a Box-Behnken design (BBD) were utilized for exploring the effect of base used (A), temperature of reaction (B) and (C), reaction time...

Antimicrobial peptides (AMPs) are innate molecules that are found in a wide variety of species ranging from bacteria to humans. In recent years, excessive usage of antibiotics resulted in development of multi-drug resistant pathogens which made researchers to focus on AMPs as potential substitute for antibiotics. Lily type mannose-binding lectin is an extended super-family of structurally and evolutionarily related sugar binding proteins. These lectins are well-known AMPs which play important roles in fish defense mechanism...

The present work focused on the synthesis of β-chitosan submicron particles (CSPs) from Todarodes pacificus using mechanochemical techniques. The gladius was submitted to a sequence of mechanical and chemical treatments to synthesize β-chitin (CT), which was further deacetylated to form spherical chitosan submicron particles with an average diameter of ⩽100 nm. The surface morphology of β-chitin and CSPs was observed using electron microscopy. The degree of deacetylation (DD%), evaluated from the absorbance peak of a Fourier Transform Infrared (FTIR) spectrum, was 80 ± 2...

The antimicrobial peptides (AMPs) are multifunctional molecules which represent significant roles in the innate immune system. These molecules have been well known for decades because of their role as natural antibiotics in both invertebrates and vertebrates. The development of multiple drug resistance against conventional antibiotics brought a greater focus on AMPs in recent years. The cationic peptides, in particular, proven as host defense peptides and are considered as effectors of innate immunity. Among the various innate immune molecules, functions of pellino-1 (Peli-1) have been recently studied for its remarkable role in specific immune functions...

Carbohydrate sources play important roles in energy and growth of plants. Therefore, in this study, we investigated the optimal carbohydrate source in hairy root cultures (HRCs) of Scutellaria baicalensis infected with Agrobacterium rhizogenes strain R1000. The hairy roots were cultured in half-strength B5 liquid medium supplemented with seven different carbohydrates sources (sucrose, fructose, glucose, galactose, sorbitol, mannitol and maltose), each at a concentration of 100 mM, in order to identify the best carbon sources for the production of major flavones, such as wogonin, baicalin and baicalein...

Coumaric acid (CA) is a phenolic acid of the hydroxycinnamic acid family, and it has many biological functions such as anti-oxidant, anti-inflammatory, antidiabetic, anti-ulcer, anti-platelet, anti-cancer activities, etc. In the present study, we planned to analyse the potential molecular function of CA on skeletal muscle and preadipocytes differentiation using PCR and Western blot techniques. First, we analysed the impact of CA on C2C12 skeletal muscle differentiation. It revealed that CA treatment inhibited horse serum-induced skeletal muscle differentiation as evidenced by the decreased expression of early myogenic differentiation markers such as Myogenin and myoD via the AMP activated protein kinase- alpha AMPK-α mediated pathway...
