Nutraceuticals are the products derive from food sources with extra health benefits. They can prevent malignant processes. The term ‘nutraceuticals’ combines two words ‘nutrients ( a nourishing food component ) and ‘pharmaceuticals’(a medical drug ) The philosophy behind nutraceuticals is according to Hippocrates “ Let food be your medicine”. Categories of nutraceuticals are dietary supplements, functional food, medicinal food, pharmaceuticals. Advance age is often characterized by a declined in large spectrum of cognitive abilities including reasoning, memory, perceptual speed and language. Alzheimer’s disease (AD) is the most common and feared from dementia representing circa 70% of all dementia cases and displaying a dramatic epidemics due to the enormous growth of the aged population worldwide. It is still unclear which factors lead to molecular cascade of neurode generation in AD, but along with genetic environmental factors vascular pathology and risk factor have been recently shown to play crucial role in AD pathogenesis .AD impacts dramatically on everyday life of older adults, being one of the main cause of disability in old age. There is clear evidence that a diet rich in specific nutritional food group (fruit, fish, vegetables) can reduce the incidence and prevalence of some of the main clinical outcomes, such as neurodegenerative disorders, cardiovascular diseases, diabetes, cancer. This specific nutritional food group are rich in micronutrients and vitamins are beneficial for health. The Mediterranean diet is characterized by a high consumption of plant food, fish olive oil as primary source of monounsaturated fat and moderate intake of wine. In this article, we focus our attention on group of substance proposed to prevent or treat Alzheimer’s disease.

The current research work focuses on the conventional bio-catalysed synthesis of amyl levulinate with immobilized Candida antarctica lipase B in the absence of a toxic solvent. The green catalyst and solvent free system offered considerable benefits like mild and gentle condition requirement, lesser-energy demand, easy down-streaming and reusability of the biocatalyst. The process parameters were examined, and the maximum conversion (73.2%) was obtained under the optimum condition of 50℃ temperature, 1:3 molar ratio of levulinic acid to amyl alcohol using 0.8% (w/v) biocatalyst at 250 rpm speed. The immobilized lipase was characterized by SEM, BET, XRD, FTIR and amyl levulinate was characterized by FTIR and GC-MS analysis. The enzyme lipase was effectively reused till 5 cycles for the formation of ester. The thermodynamic parameters (ΔH, ΔG, and ΔS) and energy of activation (Ea) were determined for the assessment of energy requirement. The activation energy was determined to be 48.42 kJ/mol. The research protocol strikes the development of biocatalytic synthetic route of amyl levulinate without using any toxic solvent, which may contribute to green chemistry approach.

The present study evaluates the potential use of ultrasound irradiation to synthesize decyl oleate using Fermase CALBTM10000 under the solvent-free system (SFS). The optimal condition to achieve a maximum yield of 97.14% was found to be 1:2 oleic acid:decanol ratio, 1.8% (w/w) enzyme loading, 45°C temperature, 200 rpm agitation speed, 50 W power input, 50% duty cycle, 22 kHz frequency and reaction time of 25 minutes. The thermodynamic study was done to determine the change in entropy, Gibb's free energy, and change in enthalpy at various temperatures. The experimental results and kinetic study showed that the reaction followed ordered bi-bi model with kinetic parameters as rate of reaction (V max ) = 35.02 M/min/g catalyst, Michaelis constant for acid (K A ) = 34.47 M, Michaelis constant for alcohol (K B ) = 3.31 M, Inhibition constant (Ki) = 4542.4 M and sum of square error (SSE) = 0.000334. The application of ultrasound irradiation combined with biocatalyst and the absence of solvent intensified the process compared to the traditional stirring method using hexane as solvent.

Objectives. To adapt and extend an existing typology of vaccine misinformation to classify the major topics of discussion across the total vaccine discourse on Twitter. Methods. Using 1.8 million vaccine-relevant tweets compiled from 2014 to 2017, we adapted an existing typology to Twitter data, first in a manual content analysis and then using latent Dirichlet allocation (LDA) topic modeling to extract 100 topics from the data set. Results. Manual annotation identified 22% of the data set as antivaccine, of which safety concerns and conspiracies were the most common themes. Seventeen percent of content was identified as provaccine, with roughly equal proportions of vaccine promotion, criticizing antivaccine beliefs, and vaccine safety and effectiveness. Of the 100 LDA topics, 48 contained provaccine sentiment and 28 contained antivaccine sentiment, with 9 containing both. Conclusions. Our updated typology successfully combines manual annotation with machine-learning methods to estimate the distribution of vaccine arguments, with greater detail on the most distinctive topics of discussion. With this information, communication efforts can be developed to better promote vaccines and avoid amplifying antivaccine rhetoric on Twitter.

Background: Studies concerning pediatric lichen sclerosus are limited, and, to date, there have been no studies comparing the course of lichen sclerosus in boys and girls. We sought to examine all publications on boys and girls with lichen sclerosus and assess and compare epidemiology, symptoms and signs, genetic background, risk factors, treatment, and prognosis. Methods: A systematic search was performed in the Embase, Medline, Cochrane, and Web of Science databases. Inclusion criteria were information on children ages 0–18 years and a clinical or histologic diagnosis of lichen sclerosus. Literature from 1985 to 2021 was reviewed. Results: A total of 1780 articles were retrieved from the search, of which 90 articles were eligible for inclusion. Boys and girls present similarly on many aspects; nonetheless, treatment and follow-up are approached differently. Conclusions: Though the clinical approach is often different, lichen sclerosus in boys and girls demonstrates many similarities. More research is needed, especially on follow-up, to gain a better understanding of the course of lichen sclerosus and establish an advanced management plan for children.

Nano-sized materials have been an important tool in basic and applied sciences. A novel, low cost, green and reproducible bacteria, Staphylococcus aureus mediated biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) was reported in the present study. Initial conformational studies were done using UV-visible spectroscopy and confirmed the synthesis of TiO2 NPs in the broth. The detailed characterization of the TiO2NPs was carried out using SEM, XRD, FTIR and Raman spectroscopy. From the SEM, it was confirmed that the sample showed the NPs were smooth and spherical with an average diameter of about 20nm. From FTIR analysis, it was confirmed that the TiO2 nanoparticles are crystalline in nature, which was confirmed by the FTIR peak at 518cm-1 corresponds to the TiO2 vibration present in a crystalline structure. Additionally, the synthesized NPs were also characterized by Transmission Electron Microscopy (TEM) and Particle size analyzer. This study was aimed to determine the antibacterial and antibiofilm activity of Titanium oxide nanoparticles against both Gram-positive and Gram-negative bacterial species and significant positive results against Bacillus subtilis and Escherichia coli were observed.

The conventional flavor synthesis method suffers from low yields, time inefficiency, and extreme reaction conditions. Therefore, there is a necessity for the green and novel synthesis approach to overcome these limitations. The current review presents a holistic insight into different aspects associated with the synthesis of flavor esters using the immobilized enzyme. The application of process intensification tools such as ultrasound and microwave irradiation can enhance the reaction efficiency because of higher product recovery, less formation of by-products, and decreased energy consumption. This review presents the process intensification of value-added flavor esters synthesis and the mechanism of ultrasound and microwave action on the enzyme to enhance the enzyme activity and increase the reaction rate. It also summarizes the role of process intensification in enzymatic flavor ester synthesis, followed by specific examples as reported in the literature.
