Review | 2016 | Journal of Hygienic Engineering and Design17 , pp.28 - 33

It is believed that almond is rich in terms of vitamin E, copper, phosphor, manganese, magnesium, potassium, fiber, riboflavin, monounsaturated fatty acids and protein. Because of its special composites of antioxidants such as: isorhamnetin, quercitrin, kaempferol, quercetin, catechin, epicatechin, naringenin, cyanidin, delphinidin, 3-O-rutinoside, isorhamnetin 3-O-glucoside, morin, caffeic acid, ferulic acid, p-coumaric acid, protocatechuic acid and vanillic acid, it is stated that almond is in special position in terms of human nutrition. Antioxidants have a significant impact on DNA’s damage inhibition as preventing LDL cholester . . .ol oxidation. In numerous researches which have been studied about almond’s effects on human health, the fat and fatty acids composition of almond’s varieties have been determined and it has been expressed that almond: is rich in respect to monounsaturated fatty acids, it has oleic acid which is one of fatty acid that has the role of reducing cholesterol level in blood, and it has linoleic acid which prevents intravenous restriction. Almond is the best source among other nuts in terms of vitamin E which is known as the soluble lipid phenolic antioxidant. It has been indicated that vitamin E has an important role in order to prevent diabetes, atherosclerotic vascular diseases and some of cancer diseases. Further, almonds have a low glycemic index and do not adversely impact insulin sensitivity. While benefits of almonds for cardiovascular health and obesity-related diseases appear promising, the potential allergenic reaction among susceptible individuals can present a risk. L-Arginine in almond has been shown to be a powerful mediator of multiple biological processes, including the release of several hormones, collagen synthesis during wound healing, antitumour activity and immune cell responses. Almond oil is used today by massage therapists for its many natural emollient and skin-rejuvenating properties. Moreover, it may have a beneficial effect in the management of irritable bowel syndrome. Besides, almond is a good source of mineral compounds particularly: calcium, magnesium, phosphorus and potassium. These compounds have important contributions to human health in terms of balancing the hypertension, comprising the bone and teeth, blood forming, nerve stimulation, growth and gender development and muscular tissue activity. Researches which have been studied on almond’s nutritional aspects, support the approach that almond is a functional nutrient which has a medical benefit on treatment of some diseases. © 2016, Consulting and Training Center – KEY.

The effect of anthelmintic triclabendazole on survival and development of Galleria mellonella (Lepidoptera: Pyralidae) L. reared on artificial diet.

Kılıç, Ali | Büyükgüzel, Kemal | Büyükgüzel, Ender


The effect of triclabendazole, which is a benzimidazole anthelmintic, on the survival rate and developmental time in different stages of greater wax moth Galleria mellonella (L.) was investigated by rearing the larvae on the artificial diets. Triclabendazole was incorporated into diets at concentrations of 0.001, 0.01 or 0.1%. G. mellonella larvae was reared from first instar larvae to adult emergence on the artificial diets with different concentrations of triclabendazole. The survival rate in seventh instar (7th-instar) and adult stage were significantly lower at low concentrations of this anthelmintic agent (0.001 and 0.01 g per . . .100 g of diet) than the control, while there were no differences on pupation in comparison to control diet. However, the pupation and adult emergence were significantly lower at the highest dietary concentration of triclabendazole than control group but there were no differences on survival of 7th-instar larvae. The highest concentration of the anthelmintic agent (0.1 g/100 g diet) decreased pupation from 81.6 +/- 4.32% to 43.3 +/- 7.45%, adult emergence rate from 73.3 +/- 2.36 to 13.3 +/- 2.36. Triclabendazole at the highest concentration prolonged developmental time to 7th larval stage by 3.8 days reaching total 22.8 +/- 1.54 days. This diet containing 0.1% of triclabendazole significantly prolonged pupal developmental time from 24.6 +/- 1.24 days to 28.4 +/- 1.24 days, adult developmental time from 35.3 +/- 1.27 days to 42.0 +/- 1.62 days. This study is of importance in appreciation for usage of antihelmintic with different structure and mode of actions in the management of pest insects to reduce damage to environment and nontarget organisms Daha fazlası Daha az

Plant allelochemicals are nonnutritional chemicals that interfere with the biology of herbivores. We posed the hypothesis that ingestion of a glycoalkaloid allelochemical, ?-solanine, impairs biological parameters of greater wax moths Galleria mellonella. To test this idea, we reared wax moths on artificial diets with 0.015, 0.15, or 1.5 mg/100 g diet of ?-solanine. Addition of ?-solanine to the diet affected survival of seventh-instar larvae, pupae, and adults; and female fecundity and fertility. The diet containing the highest ?-solanine concentration led to decreased survivorship, fecundity, and fertility. The diets supplemented . . .with ?-solanine led to increased malondialdehyde and protein carbonyl contents in midgut and fat body and the effect was dose-dependent. Dietary ?-solanine led to increased midgut glutathione S-transferase activity and to decreased fat body glutathione S-transferase activitiy. We infer from these findings that ?-solanine influences life history parameters and antioxidative enzyme activities in the midgut and fat body of G. mellonella. © 2013 Wiley Periodicals, Inc Daha fazlası Daha az

Effects of gyrase inhibitors on the total protein content of Pimpla turionellae L. reared on an artificial diet

Büyükgüzel, Kemal | İçen, Ender

Article | 2004 | Journal of Entomological Science39 ( 1 ) , pp.108 - 116

The effects of antibiotics, novobiocin, nalidixic acid and oxolinic acid, singly and in combinations, on the wet weight and total protein content of the hymenopterous endoparasitoid, Pimpla turionellae L., were investigated by rearing the larvae aseptically on chemically defined synthetic diets. Oxolinic acid, at all levels tested, caused a greater increase in the total protein content of the young pupae than other antibiotics; whereas, 2.25 mg of this agent decreased both the wet weight and total protein of adults. However, this antibiotic did not affect the pupal wet weight. High levels of novobiocin increased the protein content . . .of the pupae but had no effect on that of the adults. The lowest level of this antibiotic significantly increased pupal and adult wet weight. While this level of antibiotic had no effect on pupal protein content, it significantly increased the protein content of adults. The highest tested level of nalidixic acid caused a significant decrease in the pupal and adult wet weight of the insect. This level increased total protein content of the pupae. None of the tested levels of this antibiotic had an effect on the protein content of the adults. The combinations with two antibiotics had no significant effects on the total protein content, while some increased the wet weight of the insect. Some ternary combinations of novobiocin, nalidixic acid and oxolinic acid (6.0:2.0:0.75, 6.0:2.0:3,0, and 1.5: 4.0:0.75 mg) significantly increased the total protein content in adults of the insect, and the combination of 6.0:2.0:0.75 increased the protein content and wet weight of pupae. It is suggested that these three antibiotics singly and in combination can be used in artificial rearing of this parasitoid Daha fazlası Daha az

Although acetylcholinesterase (AChE) is the primary target of organophosphorus insecticides (OPs), increasing evidence regarding their secondary effects suggests that OPs disturb homeostasis of insects by generating free radical intermediates that trigger lipid peroxidation. We therefore investigated alterations in lipid peroxidation product, malondialdehyde (MDA) content, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, in conjunction with AChE activity as biochemical stress indicators in greater wax moth, Galleria mellonella (L.) larvae for OPs methyl parathion (MP) and ethyl parathion (EP). The . . .effects of MP and EP were first investigated by rearing the young larvae on an artificial diet containing 0.01, 0.1, 1, 10, and 100 ppm of each insecticide. Second, the mature larvae were injected with 0.05, 0.5, 5, 50, and 500 ng of insecticides for determining the changes in biochemical stress responses. The diet with lowest level of MP significantly decreased the activities of all measured enzymes, whereas it increased MDA content. However ALT and AST were significantly higher in the larvae reared with the diet with high levels of MP than in control larvae. All tested levels of MP resulted in a decrease in AChE activity. The lowest level of EP in diet (0.01 ppm) significantly increased ALT activity, whereas it reduced that of AChE. This insecticide at 0.1 ppm resulted in reduced AST activity, but 1 ppm in diet elevated AST activity and MDA content. EP at 0.1 ppm and higher levels in the diet reduced ALT activity. All dietary EP levels significantly decreased AChE activity. ALT, AST, and AChE were lower in larvae fed with the diet containing 100 ppm ethyl parathion compared with larvae on control diet. MP at 50 ng per larva increased ALT and AST activities from 35.42 ± 0.74 and 26.34 ± 0.83 to 203.57 ± 1.09, and 122.90 ± 1.21 U/g, respectively, when the mature larvae were injected. All injected doses of EP dramatically reduced both ALT and AST activities, but only the lowest and highest levels of this insecticide decreased AChE activity. The lowest level of this insecticide also significantly increased MDA content in larvae. High levels of both insecticides increased MDA content. We observed a significant higher increase in MDA content in the larvae reared with 10 ppm EP (102.16 ± 1.57 nmol/g protein) than the control group (30.28 ± 1.42 nmol/g protein). These results suggest that OPs caused the metabolic and synaptic dysfunctions in greater wax moth and alter its biochemical physiology in response to oxidative stress. © 2005 Entomological Society of America Daha fazlası Daha az
