Fish-mint (Houttuynia cordata Thunb.), belongs to family Saururaceae has long been used as food and traditional herbal medicine. The present study was framed to assess the changes occurring in the essential-oil composition of Houttuynia cordata during annual growth and to evaluate allelopathic, antibacterial, antifungal and antiacetylcholinesterase activities. The essential-oil content ranged from 0.06-0.14% and 0.08-0.16% in aerial-parts and underground-stem, respectively. The essential oils were analysed by GC-FID, GC-MS and NMR ((1) H & (13) C)...

Elevated vanadium (V) concentrations in oil sands coke, which is produced and stored on the site of some major Athabasca Oil Sands companies, could pose a risk to aquatic ecosystems in northern Alberta, Canada, depending on its future storage and utilization. In the present study, V toxicity was determined in reconstituted Athabasca River water to various freshwater organisms, including 2 midge species (Chironomus dilutus and Chironomus riparius; 4-d and 30- to 40-d exposures) and 2 freshwater fish species (Oncorhynchus mykiss and Pimephales promelas; 4-d and 28-d exposures) to facilitate estimation of water quality benchmarks...

The two most abundant polycyclic aromatic hydrocarbons (PAHs) measured in the Deepwater Horizon (DWH) crude oil, naphthalene and phenanthrene and their associated homologs, have both been shown to be acutely toxic in fish. Although fish have a relatively high metabolic capacity for PAHs, hydroxylated PAH (OH-PAHs) derivatives formed during the initial metabolic response can negatively impact the health of fish. Species-specific metabolism of naphthalene and phenanthrene was evaluated in three marine teleosts, red drum (Scianops ocellatus), Florida pompano (Trachinotus carolinus) and southern flounder (Paralichthys lethostigma)...

Taking fish oil supplements in the third trimester of pregnancy was associated with significantly less wheezing or asthma in the child at the age of 3-5 years, according to a randomized clinical trial by Bisgaard et al., NEJM 2017. However, the results of this study should be interpreted with caution. The primary end points were modified at a late stage in the study, and two primary end points, eczema in the first 3 years of life and allergic sensitization at 18 months of age, were demoted to secondary end points, and showed no significant effect of treatment...

The development of vaccines for aquaculture has been an important milestone in providing a continuous and sustainable production. Most of the vaccines currently on the market for aquaculture include oil as adjuvant. Nevertheless, several studies reported an occurrence of side effects after their use in farmed fish. As a result, there is a need for new and improved adjuvants that can stimulate the immune system while causing as few side-effects as possible. Hemocyanins are versatile macromolecules with strong immunogenic and immunomodulatory properties...

High insulin levels in obese people are considered as a risk factor to induce breast carcinogenesis. And consumption of fish oils which mainly contain omega-3 fatty acids is associated with a reduced risk of breast cancer. However, whether omega-3 free fatty acids (FFAs) modulate insulin signaling pathway to prevent breast cancer is poorly understood. The current study tested the hypothesis that omega-3 FFAs attenuate insulin-induced breast cancer cell proliferation and regulate insulin signaling pathway. We show here that omega-3 FFAs attenuate MCF-7 cell proliferation and Akt and Erk1/2 phosphorylation levels stimulated by insulin...

The moisture content of β-cyclodextrin/Danube fish oils complexes (common barbel, Pontic shad, European wels catfish, common bleak) was evaluated by thermal methods. Saturated and monounsaturated fatty acids were the most concentrated in fish oils (25.3-30.8% and 36.1-45.0%). ω-3 And ω-6 fatty acids were identified in low concentrations of 2.8-12.1% and 4.1-7.1%. The moisture content was significantly lowered after β-CD complexation, as revealed by thermogravimetric (TG) analysis (13.3% for β-CD, 2.5-6...

Most existing fish vaccines are presented in the form of oil-based emulsions delivered by intraperitoneal injection. Whilst very effective they are frequently associated with inflammatory responses that can result in clinically significant side-effects often involving the adipose tissue that is in direct contact with the vaccine. To explore the potential of immune gene expression changes in the adipose tissue of fish to be markers of vaccination efficacy or development of side-effects we have studied the response to a bacterial (Aeromonas salmonicida) vaccine administered with two different adjuvants...

Thomas Ms Wolever
High yogurt intake is associated with a reduced risk of type 2 diabetes (T2DM). Although several mechanisms could explain this association, this paper addresses the glycemic and insulinemic impact of yogurt. There is evidence that low-glycemic index (GI) and low-glycemic load (GL) diets are associated with a reduced risk of T2DM. The 93 GI values for yogurt in the University of Sydney's GI database have a mean ± SD of 34 ± 13, and 92% of the yogurts are low-GI (≤55). The 43 plain yogurts in the database have a lower GI than the 50 sweetened yogurts, 27 ± 11 compared with 41 ± 11 (P < 0...

Increase in organic waste generation, dwindling nature of global oil reserves coupled with environmental challenges caused by waste oil disposal and burning of fossil fuels necessitated the need for alternative energy resources. Waste cooking oil obtained from the frying fish outlet was analyzed for its physicochemical properties using ASTM D-975 methods. Acid and Iodine values of the oil were 30.43 ± 0.32 mgKOH/g and 57.08 ± 0.43 mgI2/100 g respectively. Thermo-chemical conversion of the oil using NiO/SiO2 at different reaction conditions (pressure, temperature, and catalyst concentration) at a residence time of 3 h yielded 33...

Docosahexaenoic acid (DHA), an ω-3 fatty acid abundant in fish oils, has diverse health beneficial effects, such as anti-oxidative, anti-inflammatory, neuroprotective, and chemopreventive activities. In this study, we found that DHA induced expression of two representative antioxidant/cytoprotective enzymes, heme oxygenase-1 (HO-1) and NAD(P)H:quinone oxidoreductase (NQO1), in human mammary epithealial (MCF-10A) cells. DHA-induced upregulation of these enzymes was accompanied by enhanced translocation of the redox-sensitive transcription factor Nrf2 into the nucleus and its binding to antioxidant response element...

The modulation of milk fat nutritional quality through fish oil supplementation seems to be largely explained by the action of n-3 very long chain polyunsaturated fatty acids (PUFA) on ruminal biohydrogenation (BH) of C18 fatty acids (FA). However, relationships among this action, disappearance of those PUFA in the rumen, and potential detrimental consequences on ruminal fermentation remain uncertain. This study compared the effect of 20:5n-3 (eicosapentaenoic acid; EPA), 22:5n-3 (docosapentaenoic acid; DPA), and 22:6n-3 (docosahexaenoic acid; DHA) on rumen fermentation and BH of C18 FA and was conducted simultaneously in cows and sheep to provide novel insights into interspecies differences...

One of the primary sources of polycyclic aromatic hydrocarbons (PAHs) in marine environments is oil. Photochemical oxidation and microbial transformation of PAH-containing oils can result in the formation of oxygenated products. Among the PAHs in crude oil, chrysene is one of the most persistent within the water column and may be transformed to 2- and 6-hydroxychrysene (OHCHR). Both of these compounds have been shown to activate (2-OHCHR) and antagonize (6-OHCHR) the estrogen receptor (ER). Previous studies in our lab have shown that estrogen can significantly alter zebrafish development...
