Dietary butter protects against ultraviolet radiation-induced suppression of contact hypersensitivity in Skh:HR-1 hairless mice.

Dietary fats modulate a wide variety of T cell functions in mice and humans. This study examined the effects of four different dietary fats, predominantly polyunsaturated sunflower oil, margarine, and predominantly saturated butter, clarified butter, on the T cell-mediated, systemic suppression of contact hypersensitivity by ultraviolet radiation in the Skh:HR-1 hairless mouse. Diets containing either 200 g/kg or 50 g/kg butter or clarified butter as the sole fat source protected against systemic photoimmunosuppression, whether the radiation source was unfiltered ultraviolet B (280-320 nm) or

Breeding and maintenance of an Mecp2-deficient mouse model of Rett syndrome.

In this report, we present a retrospective assessment of our experiences in maintaining a colony of Mecp2-deficient mice, and present conditions that we have found to foster breeding success of this mutant mouse strain. Data from our colony of mutant Mecp2 mice show that the Mecp2-null allele is under-represented in the weaned litter population, that litters born to heterozygous Mecp2-null females are consistently smaller in number than wild-type, and that fewer litters from heterozygous Mecp2-null females survive to weaning age than wild-type. Our results also reveal that overall litter viabi

Carthami flos extract against carbon tetrachloride-induced liver fibrosis via alleviating angiogenesis in mice.

BACKGROUND: Angiogenesis is a pathological phenomenon contribute to the development of chronic liver diseases, and anti-angiogenic therapy is an effective strategy to alleviate liver fibrosis. Carthami flos, a medicinal and edible herb, has the effects of improving blood circulation and regulating angiogenesis. However, the anti-angiogenic effect of Carthami flos in liver fibrosis remains unknown. METHODS: We investigated the protective effect and therapeutic mechanism of Carthami flos extract (CFE) on carbon tetrachloride (CCl4)-induced liver fibrosis in mice. The liver injury and collagen d

Physiological role of exogenous nitric oxide in improving performance, yield and some biochemical aspects of sunflower plant under zinc stress.

The present study was undertaken to examine the possible roles of sodium nitroprusside in protection against oxidative damage due to zinc toxicity in sunflower plants. Physiochemical parameters in sunflower plants exposed to Zn2+ (100, 200 and 300 mg/kg soil) alone or combined with SNP were measured. The results showed that excess of Zn decreased plant growth, seed yield components and photosynthetic pigments content. On the other hand, Zn stress increased the level of non-enzymatic antioxidants (ascorbic acid and reduced glutathione) and enzymatic antioxidants (superoxide dismutase, ascrobate

Plant inner membrane anion channel (PIMAC) function in plant mitochondria.

To date, the existence of the plant inner membrane anion channel (PIMAC) has been shown only in potato mitochondria, but its physiological role remains unclear. In this study, by means of swelling experiments in K(+) and ammonium salts, we characterize a PIMAC-like anion-conducting pathway in mitochondria from durum wheat (DWM), a monocotyledonous species phylogenetically far from potato. DWM were investigated since they possess a very active potassium channel (PmitoK(ATP)), so implying a very active matching anion uniport pathway and, possibly, a coordinated function. As in potato mitochondri

Lower pregnancy losses in lactating dairy cows fed a diet enriched in alpha-linolenic acid.

The objectives were to determine if a diet enriched in alpha-linolenic acid (ALA) would influence ovarian function, early embryo survival, conception rates, and pregnancy losses in lactating dairy cows. Beginning 28 d before breeding, Holstein cows (55 +/- 22 d postpartum; mean +/- SD) were assigned to diets supplemented with either rolled flaxseed (FLAX; 56.7% ALA, n = 62) or rolled sunflower seed (SUNF; 0.1% ALA, n = 59) to provide approximately 750 g of oil/d. Diets continued for 32 d after timed artificial insemination (TAI, d 0) following a Presynch/Ovsynch protocol. Barley silage- and ba

[Role of phytotherapy in the prevention and treatment of obesity].

The rapidly increasing prevalence of overweight and diabetes mellitus is a serious global threat to healthcare. Nowadays, medicinal plants and natural treatments are becoming more and more popular. Diabetes has historically been treated with plants or plant derived formulations in different cultures, mainly in China, Asia and India. Different mechanisms for the antidiabetic effect of plants have been proposed: increased release of insulin, reduction of intestinal glucose absorption, enhancement of glycogen synthesis. The scientific evidences for most of these plants are still incomplete. The l

Identification of angiotensin converting enzyme and dipeptidyl peptidase-IV inhibitory peptides derived from oilseed proteins using two integrated bioinformatic approaches.

Angiotensin-converting enzyme (ACE) and dipeptidyl peptidase-IV (DPP-IV) play critical roles in the development of hypertension and type 2 diabetes, respectively. Inhibiting ACE and DPP-IV activity using peptides has become part of new therapeutic strategies for supporting medicinal treatment of both diseases. In this study, oilseed proteins, including soybean, flaxseed, rapeseed, sunflower and sesame are evaluated for the possibility of generating ACE and DPP-IV inhibitory peptides using different integrated bioinformatic approaches (UniProt knowledgebase, ProtParam, BLAST, BIOPEP, PeptideRan

Chronic botulism in a Saxony dairy farm: sources, predisposing factors, development of the disease and treatment possibilities.

The aim of this study is to investigate Clostridium botulinum at a Saxony dairy farm with 159 cows and 18 heifers. The animals exhibited clinical symptoms of chronic botulism. To determine the source of the infection, feces, blood, organs, and gastrointestinal fluids of dead or euthanized cows; as well as soil, water, silage and manure were tested for C. botulinum spores and BoNTs using ELISA. BoNT/C and C. botulinum type C were detected in 53% and 3% of tested animals, respectively, while BoNT/D and C. botulinum type D were detected in 18% of the animals.

Decreased food efficiency ratio, growth retardation and changes in liver fatty acid composition in rats consuming thermally oxidized and polymerized sunflower oil used for frying.

Changes in food intake, body weight, liver weight, hepatosomatic index and hepatic fatty acid composition were studied in growing male Wistar rats fed a diet containing sunflower oil that had been used repeatedly for frying. During a period of 27 days, the animals were fed semi-synthetic diets containing either 15% used oil with 19.1% polar material (group 2) or 15% unused oils with 5.1% polar material (group 1). Although food intake was similar in both experimental groups, final body weight, body weight gain, food efficiency ratio and protein efficiency ratio were significantly lower in group

Adjuvant Properties of Caffeic Acid in Cancer Treatment.

Caffeic acid (CA) is a polyphenol belonging to the phenylpropanoid family, commonly found in plants and vegetables. It was first identified by Hlasiwetz in 1867 as a breakdown product of caffetannic acid. CA is biosynthesized from the amino acids tyrosine or phenylalanine through specific enzyme-catalyzed reactions. Extensive research since its discovery has revealed various health benefits associated with CA, including its antioxidant, anti-inflammatory, and anticancer properties. These effects are attributed to its ability to modulate several pathways, such as inhibiting NFkB, STAT3, and ERK
