Objective: Starvation have pro-oxidative effect as a consequence of both elevated ROS generation and defeat in neutralization of ROS. Aloe vera juice induced oxidative stress and significantly decreased antioxidant enzymes levels. The main aim of this experiment was to evaluate the effect of Aloe vera gel extract on oxidative stress status during long period starvationMethod: Twenty-four mature male albino Wistar rats were housed in standard cages. In this study starvation cycle (rats were starved for two days and then were fed for one day) was used. This study was performed during intermediate period (60 days).Animals were divided into four experimental groups (six rats in each group): 1) normal control; 2) starved rats + water/ethanol; 3) starved rats + hydro-alcoholic Aloe vera gel extract (100 mg/kg); 4) starved rats + hydro-alcoholic Aloe vera gel extract (200 mg/kg); 5) Without starvation with hydro-alcoholic Aloe Vera gel extract (100 mg/kg); 6) Without starvation with hydro-alcoholic Aloe Vera gel extract (200 mg/kg). Blood samples were obtained using cardiac puncture. In blood samples, antioxidant enzymes including SOD, GPx and catalase, antioxidant trace elements including copper, zinc and magnesium and antioxidant vitamins including vitamin A, vitamin E and vitamin C were measured Results: Plasma levels of antioxidant enzymes (SOD,GPX and catalase) significantly decreased in starved rats + water/ethanol group (P< 0.05). Plasma levels of antioxidant enzymes after treatment with hydro-alcoholic Aloe vera gel extract at doses 100 and 200 mg/kg were significantly increased (P < 0.05). Also, plasma levels of antioxidant enzymes in normal rats (without starvation) after treatment with hydro-alcoholic Aloe vera gel extract at doses 100 and 200 mg/kg were significantly increased (P < 0.05). Plasma levels of Cu, Zn and Mn in normal control group had no significant difference with starved rats + water/ethanol and starved rats + hydro-alcoholic Aloe vera gel extract in 100 and 200 mg/kg dose groups (P > 0.05). Plasma levels of vitamin A and E in normal control group had no significant difference with starved rats + water/ethanol and starved rats + hydro-alcoholic Aloe vera gel extract in the 100 and 200 mg/kg dose groups (P > 0.05). Plasma level of vitamin C significantly decreased in starved rats + water/ethanol group (P < 0.05). Plasma level of vitamin C after treatment with hydro-alcoholic Aloe vera gel extract at doses 100 and 200 mg/kg was significantly increased (P < 0.05). Also, plasma level of vitamin C in normal rats (without starvation)  after treatment with hydro-alcoholic Aloe vera gel extract at doses 100 and 200 mg/kg was significantly increased (P < 0.05)Conclusion:In concluding our results it is shown that intermediate period starvation caused  an increase in oxidative stress via impairing of antioxidant defense and Aloe vera treatment is able  to improve antioxidative defense induced by starvation

Background: The putative functions of the cellular prion protein (PrPc) are believed to be associated with cell signaling, differentiation, survival, and cancer progression. With respect to cancer development and progression, elevations and mutations of PrPc expression have been shown to increase the risk for malignancy and metastasis in breast and colorectal cancer. Since both natural supplements and direct regulation of PrPc expression contribute to inhibition of cancer progression and growth, we hypothesized that knockdown of PrPc could lead to an enhanced synergic effect on the inhibition of cancer growth by fucoidan. Materials and Methods: PrPc expression was suppressed in HT29 human colon cancer cells by utilizing small-interfering RNA (si-PRNP), and cells were subsequently used to study the antiproliferative and anticancer effects of fucoidan treatment of HT29 human colon cancer cells. Results: Fucoidan treatment significantly inhibited growth and reduced cyclin and cyclin-dependent kinase (CDK) expression in HT29 colon cancer cells. Furthermore, silencing PrPc expression with si-PRNP amplified the fucoidan-induced changes in cell proliferation, apoptosis, and migration. Intraperitoneal injection of si-PRNP with fucoidan reduced proliferation and tumor volume in Balb/c nude mice. This enhanced antitumor efficacy was associated with decreased angiogenesis. Conclusion: Combination of fucoidan with silencing of PrPc has a synergic effect on the inhibition of HT29 colon cancer cell growth. Furthermore, we provide evidence for the therapeutic application of PrPc silencing with other anticancer drugs for cancer.

PURPOSE: To compare the therapeutic effect of sodium hyaluronate (SH)–trehalose (Trehalube, Microlabs, Bangalore, India, SH 0.1% and trehalose 3%) or SH (0.1% Hylotears, Raymed, Chandigarh, India) alone in patients with dry eye disease (DED).MATERIALS AND METHODS: Patients were randomized into two groups: SH-trehalose (SH 0.1% and trehalose 3%) or SH (0.1% Hylotears) alone. The Ocular Surface Disease Index (OSDI) questionnaire was used to assess patient's symptoms. Patients were followed up at 4 and 8 weeks, and OSDI score, tear film break-up time (TBUT), tear film height (TFH), Schirmer's test, and conjunctival staining were evaluated at each visit.RESULTS: A total of 384 patients were included in the study, 192 patients in each arm. The mean age of participants was 37.62 + 14.4 years and 225 were women (56%). The improvement in Schirmer's test was significantly better in the SH-trehalose group at 8 weeks (5.26 + 4.3 mm, 95% confidence interval = 4.6–5.9 mm) compared to the SH group (3.71 + 3.9, 95% confidence interval = 3.15–4.28 mm). The TBUT and TFH showed slight improvement at 4 weeks in both groups, but not at 8 weeks. There were no group differences at all-time points in terms of conjunctival staining and OSDI-based grades of DED.CONCLUSION: It was found that treating dry eye with SH-trehalose leads to greater improvement in the Schirmer's values and TBUT after 8 weeks of sustained use in patients with DED, and this was more pronounced in those with severe DED.

Background For scavenging reactive oxygen species, plant possess effective system that protect them from destructive oxidative reaction. Parts of this system as osmoprotectants and antioxidative enzymes are key elements in the defense mechanisms. A field experiment was conducted to evaluate the potential of foliar treatment of trehalose (Tre) with different concentrations (0, 0.1 mM, or 0.5 mM) in improving antioxidant defense system of quinoa plant under normal irrigation and drought stress conditions. Results Drought stress caused significant increases in some osmoprotectants as glucose, trehalose, TSS, free amino acids, and proline. Meanwhile, trehalose foliar treatment with different concentrations significantly decreases in free amino acids and proline contents. More accumulation of the tested organic solutes of leaves (glucose, sucrose, trehalose, TSS) of the trehalose-treated plant in both normal irrigated and drought-stressed quinoa plants as compared with the corresponding controls. Treating quinoa plants with trehalose resulted in significant decrease in lipid peroxidation, hydrogen peroxide contents, and LOX activity in normal irrigated and drought-stressed plants. These decreases correlated with significant increases in total phenolic contents as compared with untreated control. Different concentrations of trehalose resulted in significant increases in antioxidant enzymes. Maximum increase antioxidant enzymes were observed by treating plants Tre at 0.5 mM either under normal irrigation or drought conditions. Conclusion It could be concluded that foliar spray of trehalose was effective in improving quinoa performance by reducing hydrogen peroxide free radical and by enhancing antioxidant compounds (phenolics), compatible osmolytes, membrane stability, and antioxidant enzymes.

Introduction Aloe Vera is a plant that belongs to the Aasphodelacea (Liliaceae) family has been used as an herbal medicine for centuries. It is native to Africa and many Mediterranean countries and is used for several healing purposes, like treating various skin disorders such as abcesses, burns and eczema. Its juice

The antiviral activity in vitro and in vivo and the effect of the immune system of two fucoidan fractions with low molecular weight and different sulfate content from Laminaria japonica (LMW fucoidans) were investigated in order to examine the possible mechanism. In vitro, I-type influenza virus, adenovirus and Parainfluenza virus I were used to infect Hep-2, Hela and MDCK cells, respectively. And 50% tissue culture infective dose was calculated to detect the antiviral activity of two LMW fucoidans. The results indicated that compared with the control group, 2 kinds of LMW fucoidans had remarkable antiviral activity in vitro in middle and high doses, while at low doses, the antiviral activity of 2 kinds of LMW fucoidans was not statistically different from that in the blank control group. And there was no statistically difference between two LMW fucoidans in antiviral activity. In vivo, LMW fucoidans could prolong the survival time of virus-infected mice, and could improve the lung index of virus-infected mice significantly, which have statistical differences with the control group significantly (p < 0.01). However, the survival time of the two LMW fucoidans was not statistically significant (p > 0.05). In this study, it was shown that both of two LMW fucoidans (LF1, LF2) could increase the thymus index, spleen index, phagocytic index, phagocytosis coefficient and half hemolysin value in middle and high doses, which suggested that LMW fucoidans could play an antiviral role by improving the quality of immune organs, improving immune cell phagocytosis and humoral immunity.

ABSTRACT Objective: Micropropagation and elicitation studies of Aloe vera Methods: Standardisation of the regeneration protocol was done by using Murashige and Skoog (MS) media in combination with various plant growth regulators and elicitation studies were carried out by means of abiotic elicitors (salicylic acid, fructose and sodium chloride). Results: Direct regeneration through shoot tip gave the best response (0.2 mg/l Indole Butyric Acid (IBA) + 0.2mg/l 6-Benzylaminopurine (BAP)). Salicylic acid proved to be an effective abiotic elicitor, for suspension cultures of in vitro grown callus and also in vivo. It increased the content of polysaccharides, up to 7 times and phenolic compounds to almost 10 folds compared to untreated control kept under similar conditions. Conclusion: This study will make a path for the genetic transformation and metabolite enhancement along with their regulation, which can prove to be an asset towards pharmaceutical industry. Keywords: Aloe vera, Succulent plant, Micropropagation, Elicitation, Callus, Explant.

Fucoidan is a kind of the polysaccharide, which comes from brown algae and comprises of sulfated fucose residues. It has shown a large range of biological activities in basic researches, including many elements like anti-inflammatory, anti-cancer, anti-viral, anti-oxidation, anticoagulant, antithrombotic, anti-angiogenic and anti-Helicobacter pylori, etc. Cancer is a multifactorial disease of multiple causes. Most of the current chemotherapy drugs for cancer therapy are projected to eliminate the ordinary deregulation mechanisms in cancer cells. Plenty of wholesome tissues, however, are also influenced by these chemical cytotoxic effects. Existing researches have demonstrated that fucoidan can directly exert the anti-cancer actions through cell cycle arrest, induction of apoptosis, etc., and can also indirectly kill cancer cells by activating natural killer cells, macrophages, etc. Fucoidan is used as a new anti-tumor drug or as an adjuvant in combination with an anti-tumor drug because of its high biological activity, wide source, low resistance to drug resistance and low side effects. This paper reviews the mechanism by which fucoidan can eliminate tumor cells, delay tumor growth and synergize with anticancer chemotherapy drugs in vitro, in vivo and in clinical trials.
