Effect on the biological function of allyl isothiocyanate against COX core subunit of Sitophilus zeamais

Hua Wu

Allyl isothiocyanate (AITC) is registered in China as a biological fumigant to control root knot nematodes, which also have a potent insecticidal activity to all the stored-grain pests, especially  for controlling Sitophilus zeamais Motschulsky. Our previous study showed that mitochondrial complex IV (COX) was the primary target of AITC in adult S. zeamais and the order of AITC inhibitory activity on the core subunit was COXÔ?á> COXÔ?ó> COXÔ?í. To further study the effect on the biological function of AITC against COX core subunit of S. zeamais, we employed RNA interference (RNAi) by using double-stranded RNA (dsRNA) to knockdown three core subunits of cytochrome c oxidase (COX)-I, -II and -III in 18-day-old larvae prior to their exposure to AITC to detect susceptibility changes. The sensitivities of dsRNACOX I and II injection  treatments significantly increased at 72 h after absorption while the mortality reached up to 85.56% and 67.78%, respectively. DsRNACOX-I and dsRNACOX-II injection showed the same subcellular structural characteristics showing vacuolization and vague mitochondrial cristae and decrease of COX activity during AITC fumigation treatment, suggesting the potential of COX-I and COX-II as the targets of AITC.The silencing was efficient and specific, the mortality reached 75.55%, 71.88% and 82.22% after injection of dsRNACOX I, II and III, respectively, leading to S. zeamais larvae turning from milky white to dark brown in the thorax and whole body and eventually death. Overall, COX I and II might be potential targets of AITC and dsRNACOX I, II and III have the potential to be developed into nucleic acid pesticides and are worth pursuing for improving AITC fumigation activity in pest control.

Danial Khayatan

In recent years, the application of nanotechnology in cosmetics and pharmaceutical industry has occurred as an auspicious field to promote among its capability in increasing aqueous solubility of lipophilic functional components, encapsulating unstable bioactive compounds, and elevating skin penetration and absorption of bioactive amalgamations. Among the various nano techniques, the development of microemulsion or nanoemulsion is quite popular because of its ease in preparation. Coffee oil and algae oil can be utilized as a raw material in cosmetics. Marine algae oil is the best source for docosahexaenoic acid (DHA) and coffee oil is rich in triacylglycerol (75%) and the rest of that its components are free fatty acid, wax, and some antioxidants such as sterols, tocopherols. The polyunsaturated fatty acids like docosahexaenoic acid (DHA) which mainly exists in algae oil, is a vital fatty acid reported to possess many biological activities such as anticancer, anti-inflammation, antibacterial properties. The mixture of these two oils is evaluated thas effects on melanoma cells as well as the protective effect on UVA-induced skin damage in mice.

Methods and materials: The objectives of this study were to develop a nanoemulsion with both coffee oil and algae oil as raw materials and study its protective effect against UVA-induced skin damage in mice as well as anti-proliferative effect and mechanism on melanoma cells. Also, both coffee oil and algae oil was analyzed by gas chromatography-mass spectrometry (GC-MS).

Toxicogenomics-TGx; An emerging potential in Risk Assessment Predictive screening

Joshua Ochola

Xenobiotics, including pharmaceuticals produce toxicant specific changes at the molecular level. The completion of the human genome sequencing now allows for the detection of direct relationships between induced toxicities and gene, protein, and metabolite expression. Data gathered from Toxicogenomic approaches are proving to have higher confidence value, more discriminatory, and sensitive than currently used techniques in predictive screening of toxicants in regulatory applications and decision making. TGx analysis can complement current testing regimes in risk assessment in many areas including cross specie extrapolations, by stander and low dose exposure assessments, Dose-response relationships; to build a wealth of evidence for a successful regulatory application.

Toxicogenomics (TGx) has contributed significantly to toxicology and now has great potential to support moves towards animal-free approaches in regulatory decision making. Here, we discuss in vitro TGx systems and their potential impact on risk assessment. We raise awareness of the rapid advancement of genomics technologies, which generates novel genomics features essential for enhanced risk assessment. We specifically emphasize the importance of reproducibility in utilizing TGx in the regulatory setting.

Impact of Exogenous Melatonin on Fruit Quality and Storability of Tomato (Solanum lycopersicum L.)

Subhra Saikat Roy

our study revealed the beneficial effect of melatonin, an indole amine hormone, on food value and storability of tomato. We have taken four doses of melatonin viz. 50, 100, 250 and 500 µmol/L. Two sprays were done at fruit setting and color break stage. Application of melatonin @ 250 µmol/L was found to be advantageous in improving the carbohydrate, protein, fat, total sugar and total soluble solids content in tomato fruits as compared to control (without melatonin). Melatonin application @ 250 µmol/L showed reduced activity of polygalacturonase-I (37.16%), polygalacturonase-II (39.40%) and ascorbic acid oxidase (35.14%) as compared to control; whereas maximum reduction of polyphenol oxidase activity (28.03%) was associated with melatonin (500 µmol/L). Melatonin application on phenolics, flavonoids, ascorbic acid and antiradical activity in tomato also shown interesting results. Overall, exogenous application of melatonin @ 50 to 100 µmol/L was found to be beneficial for higher bioactivity in tomato in terms of lycopene content (15.56 ± 0.99 mg/kg of tissue), total phenolics (27.8 mg GAE/100 g), L-ascorbic acid (28.45±2.51 mg/100 g) and DPPH radical scavenging activity (12.80 mg AAE/100 g). Total flavonoids content was found to be highest (3.30 mg QE/100 g) with melatonin @ 250 µmol/L.

 Moreover, application of Melatonin (250 µmol/L) increased the shelf life up to 25 days as compared to 15 days under control at room temperature. The findings clearly suggest that application of exogenous melatonin is a potential option for enhancing food value and storability of tomato.

Uzma Ayaz

Drought stress directly affects growth along with productivity of plants by altering plant water status. Sunflower (Helianthus annuus L.) an oilseed crop, is adversely affected by biotic stresses. The present study was carried out to study the genetic variability and diversity among the sunflower genotypes at seedling stage based on different morph-physiological parameters under Polyethylene Glycol (PEG) induced stress. A total of twenty seven genotypes including two hybrids, eight advanced lines and seventeen accessions of sunflower (Helianthus annuus L.) were tested at germination and seedling stages in Polyethylene Glycol. Correlation and principle component analysis confirmed that germination percentage, root length, proline content, shoot length, chlorophyll content, Stomatal frequency and survival percentage are positively correlated with each other hence; these traits were responsible for most of variation among genotypes. The cluster analysis results showed that genotypes Ausun, line-2, line-8, 17559, 17578, Hysun-33, 17555, and 17587 as more diverse among all the genotypes. These most divergent genotypes could be utilized in the development of inbreed which could be subsequently used in the heterosis breeding.

Antioxidants against Oxidative Stress in Neurodegenerative Diseases

Zeliha Selamoglu

Chemical toxic pollutants (especially heavy metals) are important sources of reactive oxygen species (ROS) in biological systems. Membrane phospholipids of aerobic organisms are continually subjected to oxidant challenges from endogenous and exogenous sources, while peroxidized membranes and lipid peroxidation products represent constant threats to aerobic cells. The primary antioxidant protection against free radical and ROS is provided by the enzymes glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT), respectively. The trace element selenium has been implicated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals.

Flavones and flavonoids are known to have potent antioxidant activity due to intracellular free radical scavenging capacities. Flavonoids are found ubiquitously in plants as a member of polyphenolic compounds which share diverse chemical structure and properties. Quercetin is among the most efficient antioxidants of the flavonoids. The antioxidant property of quercetin has been highlighted in this review. These compounds have pivotal role in treatment of diabetes, cancers and some cardiovascular and Neurodegenerative diseases.
