Epilepsy is a disorder of episodic brain dysfunction characterized by recurrent unprovoked spontaneous seizures. Epilepsy is the second most common neurological disorder after stroke. Antiepileptic drug discovery in animal models starts with the assumption that the experimental seizure model mimics human seizure. The identification of potential therapeutic agents for the treatment of epilepsy requires the use of seizure models. Animal models for seizures and epilepsy have played a fundamental role in advancing our understanding of basic mechanisms underlying ictogenesis and epileptogenesis and have been instrumental in the discovery and preclinical development of novel antiepileptic drugs (AEDs). Most animal models cannot mimic all the pathophysiological, behavioural, electrophysiological, and neurochemical alterations of the spontaneous human epileptic syndrome. Therefore, while a selected few are used for routine screening of anticonvulsant compounds, some help in understanding mechanisms underlying epileptogenesis. In the case of antiepileptic drug development, once a compound appears promising, a battery of tests is carried out to characterize the clinical profile and possible mechanisms of action. A model for epilepsy is...

This paper focused on research on seaweed contains good nutritional source of protein, carbohydrate, pigments, vitamins, and antioxidants and has low lipid content. The source of natural substances has considered more efficient bio-molecules in building immunity and improving resistance to cancer development, prevent infections were analyzed. Classical biochemical methods were applied for extraction of pigments and other related components from red algae; subsequently, quantities of each substance were determined and discussed its potential properties. Considerable attention has been focused on pigments-based biomaterials attributes antioxidant, antitumor, and immune-modulating properties due to their multi-functional qualities. The fresh solvent extracts of K. alvarezii was found to be rich in total anthocyanin 17 mg/g.f.wt content and vitamin C 21 mg/g.f.wt. Furthermore, the efficient combination treatment with anthocyanin plus vitamin C resulted in better therapeutic efficacy than carboplatin drug against Dalton’s lymphoma tumor. The tumor cell growth was arrested due to the administration of anthocyanin plus vitamin C (500µg/kg body wt. i.p) to tumor-bearing mice; thereby the efficiency of biomolecules was confirmed. The western...

Cubosomes are very stable nanoparticles, which consist of cavernous or honeycombed structures. Cubosomes are formed from some amphiphilic lipids and stabilized by a polymer. They are known as bicontinuous cubic phase liquid crystals. The bicontinuous word refers to the two continuous but non-intersecting aqueous regions by a lipid bilayer. Cubosomes are self-assembled liquid crystalline particles of a specific ratio of water and surfactant. Self-assembled cubosomes act like an active drug delivery system. They are having rheology like a solid. Cubosomes are thermodynamically stable, and their dispersions are biocompatible as well as bio-adhesive. Cubosomes are administrable in various ways, like parenteral, oral, mucosal, transdermal, etc., for the treatment of skin, hair, or any other body tissues. Cubosomes could encapsulate the amphiphilic, hydrophilic, and also hydrophobic substances. Nevertheless, some researchers have been identifying the scope of cubosomes as delivery systems. They have different drug loading modalities and having high internal surface areas. Controlled release and targeting of bioactive agents are other abilities of cubosomes. They are also applicable as membrane bioreactors,...

Green synthesis of copper oxide nanocrystals was carried out via hydroxide precipitation using rambutan peel wastes. The successful formation of copper oxide nanocrystals was confirmed by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) analysis. XRD analysis confirms the calculated average crystallite size of higher intense plane peak (111) was 35.74 nm. SEM and TEM show the surface morphology and look flake-shaped. The AFM analysis shows needle formation of CuO nanoparticles. A possible mechanism for the formation of CuO nanocrystals with rambutan peel extract was also proposed. The prepared nanocrystals were coated on the cotton fabric, and their antibacterial activity was analyzed. Both CuO and CuO nanocrystals coated cotton fabric showed good antibacterial activity towards Escherichia coli E. coli and Staphylococcus aureus S. aureus. Wash durability test was carried out on the test fabrics showed that the significant antimicrobial activity was actively retained in the fabrics treated with CuO...

Antioxidants are renowned protective molecules that are significant in the management of many chronic diseases. They can support the free radical mechanism to quench the cellular stress to prevent oxidative damage and improve existing therapy by playing a vital role in protection through antioxidant activities. The family Amaranthaceae is a well-known family for various health benefits. The selected plants Achyranthes aspera Linn and Chenopodium album Linn are also cited in the modern and traditional literature for their diversified health applications and pharmacological properties. So, the current work aims to screen the total phenolic, flavonoid, and saponin content of fractions made with solvents with various polarities and to screen their detailed antioxidant potential through DPPH assay, NO reducing assay, reducing power assay, and total antioxidant activity. It is inferred from the results that the methanol, chloroform, and aqueous fractions were rich in antioxidant components that are statistically significant with the reference...
