BACKGROUND Differences in tea drinking habits and/or citrus peel use are likely to vary by populations and could contribute to the inconsistencies found between studies comparing their consumption and cancer risk. METHODS A population-based case-control study was used to evaluate the relationships between citrus peel use and black tea intake and squamous cell carcinoma (SCC) of the skin. More...

Regular exercise can increase the sensitivity of endogenous antioxidants so that it immune system against viral infections. Antioxidants like bioflavonoids, which are found in lemon peel essential oil, help shield body from damaging effects free radicals and immunomodulators. The goal this research was to find out whether or not frequent moderate-intensity oil boost immunity during Covid-19 Pan...

In this era, most technology requires electronic equipment. The performance of equipment may be affected by energy storage components like a supercapacitor, so the development supercapacitor electrode materials using green chemical methods needs to pursued. Material with good specific capacitance is MnO2. Most MnO2 synthesis are not based on chemistry, there an alternative method. One them util...

Temperature and pressure effects of supercritical carbon dioxide (SCCO2) on the extraction of carotenoids and seed oil from rosehip fruits have been studied. Supercritical fluid extraction (SFE) has shown much potential skills for the isolation of organic compounds from various samples. SFE minimizes sample handling, provides fairly clean extracts, expedites sample preparation and reduces the u...

The failure of an adhesive layer in a 180° peel test is analyzed by the modeling of the peel as an elastica. The adhesive is assumed to fail by a process of cavitation and fibrillation. The resistance of the fibrillated material to deformation gives rise to a rate-dependent peel force F. Governing equations, which take into account the large deformation of the fibrillated materials, are derived...

This study was designed to investigate the effects of dietary onion flesh or onion peel on lipid peroxides and DNA damage in aged rats. Sprague Dawley male rats (n=40, 16 mo old) were blocked into five groups and raised for 3 mo with either an onion-free control diet or onion diets (Allium cepa L., intermediate-day variety) containing either 5% (w/w) powdered dried onion flesh, 5% (w/w) powdere...

Chemical peels have been time-tested and are here to stay. Alpha-hydroxy peels are highly popular in the dermatologist's arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. This review talks about various studies of glycolic acid peels for various indications, such as acne, acne scars, me...

To establish the most convenient and effective method to dry tangerine peels, different methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) were exploited. Our results indicated that medium- and short-wave infrared drying was the best method to preserve nutraceutical components; for example, vitamin C was raised to 6.77 mg/g (D.W.) from...

The computer graphic simulation of a common spray painting artifact, called orange peel, is discussed. Orange peel distorts surface reflections and is commonplace in product design applications. The orange peel measurements from a standard industrial instrument are used to construct a height field, and this surface is rendered using traditional normal mapping techniques. Comparisons are made be...

in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...
