Processed meat intake is carcinogenic to humans. We have shown that intake of a workshop-made cured meat with erythorbate promotes colon carcinogenesis in rats. We speculated that polyphenols could inhibit this effect by limitation of endogenous lipid peroxidation and nitrosation. Polyphenol-rich plant extracts were added to the workshop-made cured meat and given for 14 days to rats and 100 days to azoxymethane-induced rats to evaluate the inhibition of preneoplastic lesions. Colons of 100-d study were scored for precancerous lesions (mucin-depleted foci, MDF), and biochemical end points of peroxidation and nitrosation were measured in urinary and fecal samples...

Menopause is for many females associated with an occurrence of a variety of health complaints and a decrease in quality in life. Hot flashes, sleep disturbances and a variety of other symptoms result in a strong psychological strain. Hormone replacement therapy for treatment of climacteric complaints is discussed controversially regarding associated side effects. This is a major reason to propose treatment with plant derived extracts and compounds as an alternative. Such compounds are available either as drugs but mostly as nutritional supplements...

Enhanced levels of punicic acid were produced in the seed oil of Arabidopsis over-expressing pomegranate FATTY ACID CONJUGASE driven by heterologous promoters, among which the linin promoter was the most efficient. Fatty acids with conjugated double bonds play a special role in determining both the nutritional and industrial uses of plant oils. Punicic acid (18:3Δ(9cis,11trans,13cis) ), a conjugated fatty acid naturally enriched in the pomegranate (Punica granatum) seeds, has gained increasing attention from the biotechnology community toward its production in metabolically engineered oilseed crops because of its significant health benefits...

Phenolics from free and hydrolyzed fractions of pomegranate juice (PJ) and seeds (PS) were evaluated. In general, total phenolic contents and scavenging of ABTS(+), DPPH and hydroxyl radicals, as well as metal chelation of the soluble fraction from PS, were higher than those for PJ. Insoluble-bound phenolics from PS accounted for up to 27% of total scavenging capacity (free+esterified+insoluble-bound). Phenolic acids (13), monomeric flavonoids (8), hydrolysable tannins (12), proanthocyanidin (1) and anthocyanins (12) were tentatively characterized using HPLC-DAD-ESI-MS(n)...

AIM: The occurrence of acute renal failure (ARF) cases continues to increase every year. Some of the cases are due to nephrotoxic effect caused by overdose of antibiotic consumption or abuse of the drug, gentamicin. An antibiotic therapy that can be used to overcome in such a case is the pomegranate extracts. However, until now, studies using pomegranate for cases of ARF have not been done. This study aims to determine changes in body weight, the levels of total protein (TP), and the levels of serum uric acid (UA) as a result of the pomegranate extract consumption...

Results from our previous human pomegranate extract (POM extract) intervention study demonstrated that about seventy percent of participants were able to form urolithin A from ellagitannins in the intestine (urolithin A producers). Urolithin A formation was associated with a high proportion of Akkermansia muciniphila in fecal bacterial samples as determined by 16S rRNA sequencing. Here we investigated whether A. muciniphila counts increased in stool samples collected after the POM extract intervention compared to baseline stool samples using real-time PCR...

Since natural pigments are lost during the processing of beverages such as pomegranate juice, carmoisine, as an adulterant, is often added into the pure juice to improve color characteristics. In this study, molecularly imprinted polymers, as an adsorbent of carmoisine, were synthesized using acrylamide, methacrylic acid, and 4-vinylpyridine as functional monomers and then they were evaluated in terms of the separation and detection of carmoisine. Experiments on the batch adsorption of carmoisine 10 ppm stock solution revealed a better binding capacity for the 4-vinylpyridine-based polymer in comparison to methacrylic acid and acrylamide polymers...

Majid Akrami, Mohammad Reza Sasani
Nutritional status is very important especially in older adults because of its effects on quality of life. Phytobezoar, for instance, that can lead to small bowel obstruction has risk factors such as excessive consumption of foods with high fiber content and inadequate chewing. These factors are related to dietary habits. Furthermore, aging process and some of related physiologic changes can predispose one to phytobezoar formation. We describe a 61-yr-old man presented to the Emergency Department of Nemazee Hospital, Shiraz University of Medical Sciences, Shiraz, Iran, in 2015 with small bowel obstruction due to phytobezoar following large amount of pomegranate seeds intake a few days before admission as an example of increased morbidity relating to unusual dietary habit...
