The resulting solid material possessed a surface area of 145 m g and a total pore volume of 34 cm g.

The impact of ketogenic diet on some metabolic and non-metabolic diseases: Evidence from human and animal model experiments.

The ketogenic diet (KD) is recognized as minimum carbohydrate and maximum fat intakes, which leads to ketosis stimulation, a state that is thought to metabolize fat more than carbohydrates for energy supply. KD has gained more interest in recent years and is for many purposes, including weight loss and managing serious diseases like type 2 diabetes. On the other hand, many believe that KD has safety issues and are uncertain about the health drawbacks.

Sensorial, textural, and rheological analysis of novel pistachio-based chocolate formulations by quantitative descriptive analysis.

Principal component analysis (PCA) was used to investigate the effects of pistachio oil (7.5 and 15%), xanthan gum (0 and 0.3%), distillated monoglyceride (0.

The garlic extract-loaded nanoemulsion: Study of physicochemical, rheological, and antimicrobial properties and its application in mayonnaise.

In this research, garlic extract (GE)-loaded water-in-oil nanoemulsion was used as a novel preservative and antioxidant in mayonnaise. GE (5%, 10%, 15%, and 25%) as a dispersed phase, olive oil as a continuous phase, and polyglycerol polyricinoleate (PGPR) as a low HLB surfactant, with a constant surfactant/garlic extract ratio (1:1), were used in the formulations of water-in-oil nanoemulsions. The properties of the active nanoemulsion, including droplet size, free radical scavenging capacity, antimicrobial activity against gram-positive ( []), and gram-negative ( []) were evaluated.

The physicochemical properties of the spirulina-wheat germ-enriched high-protein functional beverage based on pear-cantaloupe juice.

The formulation of a novel functional juice, enriched with wheat germ powder and spirulina algae and based on cantaloupe and pear juice, was optimized by D-optimal combined design.

Various chemical experiments including PH, acidity, formalin index, total phenol, flavonoids, antioxidant capacity, mineral contents (Fe, Zn, Ca, P, K, Mg, and Cu), and fatty acids profile were evaluated.

Bioactive content and phenolic compounds of common medlar ( L.) and Stern's medlar ( Phipps).

Medlar () is an important fruit and is rich in nutritional and medical properties. Bioactive content and phenolic compounds of leaf, fruit, and seed samples of common medlar () and Stern's medlar () were studied. The coefficient of variation showed high values among all the characters and was more than 50.

Garlic essential oil-based nanoemulsion carrier: Release and stability kinetics of volatile components.

An O/W nanoemulsion of garlic essential oil (GEO) at different oil-to-emulsion (O/E) ratios (5%, 10%, 15%, and 25%) was formulated to protect the volatile components of GEO. The effects of O/E ratios on the encapsulation efficiency (EE%) of volatile compounds and droplet size of nanoemulsions were studied. The results showed that with increasing in E/O ratio, droplet size increased while EE% decreased so that the droplet size was below 100 nm for all samples and the EE% was almost above 80% for most samples.

The role of NK and NKT cells in the pathogenesis and improvement of multiple sclerosis following disease-modifying therapies.

Background: Multiple sclerosis (MS) is an autoimmune inflammatory disease of the central nervous system (CNS) that T cells become autoreactive by recognizing CNS antigens. Both innate and adaptive immune systems are involved in the pathogenesis of MS. In recent years, the impact of innate immune cells on MS pathogenesis has received more attention.
