Novel biodegradable films were prepared by blending guar gum, chitosan and poly (vinyl alcohol) having mint (ME) and grapefruit peel (GE) extracts and crosslinked with nontoxic tetraethoxysilane (TEOS). The co-concentration effect of TEOS with natural extracts on the films was studied. FTIR analysis confirmed the presence of incorporated components and the developed interactions among the polymer chains. The surface morphology of the films by SEM showed the hydrophilic character due to porous network structure...

BACKGROUND: Platelet donors receive 40 mmol or more of IV citrate anion during donation. When plasma ionized calcium ([Ca(2+) ]) falls by ∼20%, half of the donors report symptoms of hypocalcemic toxicity. Citrus juices contain clinically relevant amounts of citrate anion. We asked whether citrus juice can lower [Ca(2+) ] thus potentially contributing to hypocalcemic toxicity. METHOD: Six volunteers were given 20.4 mmol of citrate anion as grapefruit juice or orange juice...

As our industry is continually developing more technologically advanced and expensive virtual training equipment, the grapefruit may represent an economic and accessible approach to arthroscopic simulation. This won't replace simulators, but it could become an important tool in the armamentarium of arthroscopic educators as it provides inexpensive haptic feedback necessary to create the muscle memory pathways for the improvement of arthroscopic skills.

WHAT IS KNOWN AND OBJECTIVE: Furanocoumarins, such as bergamottin (BG) and 6',7'-dihydroxybergamottin (DHB), isolated from grapefruit juice are clinically active constituents capable of inhibiting cytochrome P450 3A4. Furanocoumarins are also found in hassaku, pummelo and daidai. Several types of hybrid citrus fruits have recently been developed, and these may also contain furanocoumarins because they were produced by cross-breeding pummelo, daidai and other citrus fruits. In this study, we quantified BG and DHB levels in the flesh and peel of hybrid citrus fruits...

BACKGROUND AND AIMS: Maclura (ca. 12 spp., Moraceae) is a widespread genus of trees and woody climbers found on five continents. Maclura pomifera, the Osage orange, is considered a classic example of an anachronistic fruit. Native to the central USA, the grapefruit-sized Osage oranges are unpalatable and have no known extant native dispersers, leading to speculation that the fruits were adapted to extinct megafauna. Our aim was to reconstruct the phylogeny, estimate divergence dates, and infer ancestral ranges of Maclura in order to test the monophyly of subgeneric classifications and to understand evolution and dispersal patterns in this globally distributed group...

Sorafenib has been used as a standard therapy for advanced hepatocellular carcinoma (HCC). In Asia, patients with HCC are potentially treated with the combination of sorafenib and Chinese herbal medicines to improve the efficiency and reduce the side effects of sorafenib. However, limited information about the herb-drug interactions is available. We hypothesize that the Chinese herbal medicine may exert hepatoprotective effects on the sorafenib-treated group. The aim of this study is to investigate the pharmacokinetic mechanism of drug-drug interactions of sorafenib including interacting with hepatoprotective formulation, Long-Dan-Xie-Gan-Tang formulation (LDXGT) and with two cytochrome P450 3A4 (CYP3A4) inhibitors, grapefruit juice and ketoconazole...

During the last decade, there has been a continuous rise in consumption and global marketing of fresh, easy-to-peel mandarins, with current annual production of nearly 29 million tons. Nevertheless, most of the existing knowledge on quality traits of citrus fruit comes from research conducted on oranges and grapefruit, which are the main products for the citrus juice manufacturing industry; relatively little is yet known regarding the unique fruit quality traits of mandarins, nor about the great diversity in these traits among the various natural sub-groups and varieties of mandarins...

Flavonoids are bioactive compounds found in foods such as tea, red wine, fruits and vegetables. Higher intakes of specific flavonoids, and flavonoid-rich foods, have been linked to reduced mortality from specific vascular diseases and cancers. However, the importance of flavonoid-rich foods, and flavonoids, in preventing all-cause mortality remains uncertain. As such, we examined the association of intake of flavonoid-rich foods and flavonoids with subsequent mortality among 93 145 young and middle-aged women in the Nurses' Health Study II...

A novel stereoisomer of rotundone, 3-epi-rotundone, was identified in the aroma of grapefruit, orange, apple, and mango. 3-epi-Rotundone was prepared by the isomerization of rotundone, and its structural elucidation was confirmed by comparing the 1D and 2D nuclear magnetic resonance and nuclear Overhauser effect spectroscopy spectra with those of rotundone. The odor thresholds of rotundone and 3-epi-rotundone in water were determined by a triangle test as 5 and 19100 ng/kg, respectively. The odor of 3-epi-rotundone was evaluated as woody, spicy, peppery, citrus, grapefruit-like, powdery, and celery-like, which was a greater range of odor characteristics than that for rotundone...

Alcoholic liver disease (ALD) is a series of abnormalities of liver function, including alcoholic steatosis, steatohepatitis, and cirrhosis. Hesperidin, the major constituent of flavanone in grapefruit, is proved to play a role in antioxidation, anti-inflammation, and reducing multiple organs damage in various animal experiments. However, the underlying mechanism of resistance to alcoholic liver injury is still unclear. Thus, we aimed to investigate the protective effects of hesperidin against ALD and its molecular mechanism in this study...

Furocoumarins are a class of photoactive compounds found in several plant species and may be responsible for the observed association between consumption of citrus products and the risk of skin cancer. Furocoumarin contents of several foods have been reported previously, but no comprehensive database of furocoumarin content of foods is currently available. Therefore, this study aimed to determine the distribution of furocoumarins in popularly consumed foods in the U.S. Samples of three varieties of each of 29 foods known or suspected to contain furocoumarins were purchased, prepared for analysis using a solid phase extraction method, and analyzed using UPLC-MS/MS for the presence of seven major furocoumarins...

 Nowadays, a lot of food ingredients are marketed as dietary supplements for health. Because the effectiveness and mechanisms of these compounds have not been fully characterized, they might have unknown functions. Therefore, we investigated the effect of several food ingredients (Bergamottin, Chrysin, L-Citrulline and β-Carotene) known as health foods on adipocyte differentiation by using 3T3-L1 preadipocytes. In this study, we found that Bergamottin, a furanocoumarin isolated from grapefruit juice, promotes adipocyte differentiation...

The conservation of plant biosecurity relies on the rapid identification of pathogenic organisms, including viruses. With next-generation sequencing (NGS), it is possible to identify multiple viruses within a metagenomic sample. In this study, we explored the use of electronic probes (e-probes) for the simultaneous detection of 11 recognized citrus viruses. E-probes were designed and screened against raw sequencing data to minimize the bioinformatic processing time required. The e-probes were able to accurately detect their cognate viruses in simulated datasets, without any false negatives or positives...
