Abstract Title: 

Role of Mediterranean diet in preventing platinum based gastrointestinal toxicity in gynecolocological malignancies: A single Institution experience.

Abstract: 

BACKGROUND: Gynecological malignancies represent a major cause of death in women and are often treated with platinum-based regimens. Patients undergoing chemotherapy suffer from alterations in nutritional status which may worsen gastrointestinal (GI) toxicities, quality of life and affect the overall prognosis. Indeed, assuring a good nutritional status and limiting toxicities during treatment are still major goals for clinicians.AIM: To assess the role of Mediterranean Diet (MD) in reducing GI toxicities in patients with gynecological cancers treated with platinum-based regimens.METHODS: We conducted an observational study on 22 patients with gynecological tumors treated with a platinum-based chemotherapy at Candiolo Cancer Institute FPO/IRCCS between January 2018 and June 2018. The food and frequency (FFQ) and the Patient-Reported Outcomes Common Terminology Criteria For Adverse Events (PRO-CTCAE) questionnaires were administered at baseline and at every Day 1 of each cycle. To evaluate the differences in GI toxicities the study population was divided in two groups according to the currently validated Mediterranean Diet Serving Score (MDSS) at baseline.RESULTS: Patients with high MDSS reported a trend toward lower GI toxicities according to PRO-CTCAE at each timepoint (first evaluation:= 0.7; second:= 0.52; third:= 0.01). In particular, difference in nausea frequency and gravity (

Abstract Title: 

Impulsiveness in children with attention-deficit/hyperactivity disorder after an 8-week intervention with the Mediterranean diet and/or omega-3 fatty acids: A randomised clinical trial.

Abstract: 

INTRODUCTION: The Barratt Impulsiveness Scale (BIS) is a self-administered instrument designed to assess the personality/behavioural construct of impulsiveness. Impulsiveness has been associated with several psychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD). This study assesses the progression of impulsive behaviour in children with ADHD after an 8-week dietary intervention with the Mediterranean diet and/or omega-3 fatty acid supplementation, by using a version of the 11-item BIS adapted for children (BIS-11c).METHODS: This cross-sectional study includes 60 children with ADHD from the region of Madrid, Spain. Participants were divided into 4 groups, with one control group (G1) and 3 intervention groups (Mediterranean diet [G2]; omega-3 supplementation [G3]; and Mediterranean diet plus omega-3 supplementation [G4]). A personalised Mediterranean diet was designed for members of groups 2 and 4. The BIS-11c was administered to determine the level of impulsiveness, and the KIDMED test was used to assess adherence to the Mediterranean diet.RESULTS: The supplementation group showed a fairly significant decrease in the total BIS-11c (P=.049). Total cognitive score slightly decreased in the diet and supplementation groups. Only the control group showed a considerable decrease in the total motor score. Total nonplanning scores were lower in all groups after the intervention. Baseline and final BIS-11c scores were positively correlated with treatments (r>0.9).CONCLUSION: An intake of 550mg EPA fatty acid and 225mg DHA fatty acid per day for 8 weeks is associated with less marked impulsive behaviour in children with ADHD. A Mediterranean diet may improve BIS scores, although our results are not conclusive in this population.

Abstract Title: 

Higher Omega-3 Index Is Associated with Better Asthma Control and Lower Medication Dose: A Cross-Sectional Study.

Abstract: 

Asthma is a chronic inflammatory airway disease, associated with systemic inflammation. Omega-3 polyunsaturated fatty acids (n-3 PUFA) have established anti-inflammatory effects, thus having potential as an adjunct therapy in asthma. This study aimed to compare erythrocyte n-3 PUFA in adults with (= 255) and without (= 137) asthma and determine the relationship between erythrocyte n-3 PUFA and clinical asthma outcomes. Subjects had blood collected, lung function measured and Juniper Asthma Control Questionnaire (ACQ) score calculated. Fatty acids were measured in erythrocyte membranes by gas chromatography, and the omega-3 index (O3I) was calculated (% eicosapentaenoic acid + % docosahexaenoic acid). O3I was similar in subjects with and without asthma (= 0.089). A higher O3I was observed in subjects with controlled or partially controlled asthma (ACQ

Abstract Title: 

Antidepressant activity ofω-3 polyunsaturated fatty acids in ovariectomized rats: role of neuroinflammation and microglial polarization.

Abstract: 

BACKGROUND: Menopause predisposes individuals to affective disorders, such as depression, which is tightly related to neuroinflammation. While the neuroinflammatory condition has been demonstrated in ovariectomized (OVX) rodents, there is limited evidence concerning microglial polarization, a key process in brain immune activation, in menopause-related brain.METHODS: Therefore, the present study aims to evaluate the polarized microglia in long-term OVX rats and we further explored whether supplementation ofω-3 polyunsaturated fatty acids (PUFA), the pleiotropic bioactive nutrient, is effective in the neurobehavioral changes caused by OVX.RESULTS: Our data showed that OVX-induced anxiety and depression-like behaviors in rats, accompanied with increased neural apoptosis and microglial activation in the hippocampus. Additionally, OVX enhanced proinflammatory cytokines expression and suppressed the expression of anti-inflammatory cytokine, IL-10. Correspondingly, OVX reinforced NFκB signaling and shifted the microglia from immunoregulatory M2 phenotype to proinflammatory M1 phenotype. Meanwhile, daily supplementation with PUFA suppressed microglial M1 polarization and potentiated M2 polarization in OVX rats. In parallel, PUFA also exerted antidepressant and neuroprotectiveactivities, accompanied with neuroimmune-modulating actions.CONCLUSION: Collectively, the present study firstly demonstrated the disturbed microglial polarization in the OVX brain and provide novel evidence showing the association between the antidepressant actions of PUFA and the restraint neuroinflammatory progression.

Abstract Title: 

Protective Effect of Royal Jelly against Cyclophosphamide-Induced Thrombocytopenia and Spleen and Bone Marrow Damages in Rats.

Abstract: 

Objective: Despite the effective role of chemotherapy in cancer treatment, several side effects have been reported to date. For instance, Cyclophosphamide (CP) induces deleterious effects on both cancer and normal cells. Royal jelly (RJ) has a lot of beneficial properties, such as anti-oxidant and anti-inflammatory activities. The aim of the present study was to examine the protective effect of RJ against CP-induced thrombocytopenia, as well as bone marrow, spleen, and testicular damages in rats.Materials and Methods: In this experimental study, 48 male Wistar rats were divided into six groups (n=8/group); control, CP, RJ (100 mg/kg), RJ (200 mg/kg), RJ (100 mg/kg)+CP, and RJ (200 mg/kg)+CP groups. RJ was administered orally for 14 days. Then, CP at concentrations of 100, 50, and 50 mg/kg was intraperitoneally injected at day 15, 16, 17, respectively. The animals were sacrificed three days after the last injection of CP. Hematological parameters, serum levels of platelet factor 4 (PF4), nitric oxide (NO), and ferric reducing antioxidant power (FRAP) were measured. Also, the pathological analysis of bone marrow, spleen, and testicles was assessed.Results: CP caused a significant decrease in the number of platelets, white and red blood cells (P

Abstract Title: 

Royal Jelly (Bee Product) Decreases Inflammatory Response in Wistar Rats Induced with Ultraviolet Radiation.

Abstract: 

BACKGROUND: Ultraviolet (UV) radiation damages human skin by triggering various types of cellular damage, several main factors involved are nuclear-related factor 2 (Nrf2), nuclear factor kappa-light-chain-enhancer of activated B cells (nF-kB) and pro-inflammatory cytokine, TNF alpha. Royal jelly (RJ) possesses the effect of protecting DNA and tissue against oxidative damage.AIM: This study aimed to assess the efficacy of RJ as a protector of ultraviolet radiation, by assessing endogenous anti-oxidant expression (Nrf2), transcription factors (Nf-kB) and proinflammatory cytokines (TNF alpha).METHODS: This study was an experimental study with post-test control group design. Thirty Wistar rats were induced by exposing 40 Watt UV-B lamps for 2 hours/day in 14 days. The rats were grouped into groups with RJ cream application with doses of 2.5%, 5%, and 10%, negative control with vaseline, and normal control. Examination of Nrf2 and NF-kB levels was carried out by ELISA. Quantitative analysis to obtain the percentage of TNF alpha expression on the tissue was entered into the ImageJ® program. Bivariate analysis was carried out by the T-test.RESULTS: Nrf2 levels elevated following the increase of RJ dose, with the highest level was at RJ 10%. Nf-kB levels decreased following the increase of RJ dose, with the lowest level was at RJ 10%. TNF alpha expression was reduced in groups of RJ in various doses. Increased dose resulted in a more diminished level of TNF alpha.CONCLUSION: Royal jelly cream application protected the skin from UV radiation by increasing cellular antioxidants and suppressing inflammatory cascade.

Abstract Title: 

Royal jelly attenuates nonalcoholic fatty liver disease by inhibiting oxidative stress and regulating the expression of circadian genes in ovariectomized rats.

Abstract: 

Nonalcoholic fatty liver disease (NAFLD) has a high incidence in postmenopausal women and is accompanied by insulin resistance, obesity, and dyslipidemia. Royal jelly (RJ), a natural substance derived from hive, possesses numerous health-beneficial properties. Here, we evaluated the effects of RJ (150, 300, and 450 mg kg day, 8 weeks) on NAFLD in ovariectomized (OVX) rats. Based on the results, RJ ameliorated the degree of anxiety, improved serum lipid profile, and attenuated the hepatic steatosis and liver injury in OVX rats. Furthermore, the protective effects of RJ could be attributed to its antioxidant properties, which enhance the levels of hepatic antioxidant enzymes. The qRT-PCR results also suggest that RJ improves the disturbances of circadian genes by downregulating their expression, including that of Per1 and Per 2, in the liver of OVX rats. Altogether, our findings suggest that RJ may be a promising agent for the treatment of NAFLD. PRACTICAL APPLICATIONS: Postmenopausal women are at an increased risk of NAFLD. Currently, there are no licensed therapies for NAFLD. Although hormone replacement therapy (HRT) is reported to inhibit the development of NAFLD, it causes unexpected adverse effects. As HRT is controversial, the use of natural supplements to counteract the detrimental effects of menopause has recently attracted more attention. RJ is a natural product secreted from the hypopharyngeal and mandibular glands of worker bees. The present study illustrates the protective effect of the natural product, RJ, and its underlying mechanisms on NAFLD. This is the first study to assess the effect of RJ on NAFLD under estrogen deficiency. Such findings contribute to the further utilization of RJ, which might serve as a promising therapeutic option and natural food for the treatment of NAFLD.

Abstract Title: 

Useful impacts of royal jelly on reproductive sides, fertility rate and sperm traits of animals.

Abstract: 

Royal jelly (RJ) is one of the furthermost valuable curative products mentioned by natural medicine scientists due to its promising medical and nutritional purposes. It possesses many impacts, including antioxidants, antimicrobial, antitumor, anti-inflammatory and immunomodulatory functions in human and animal that benefit their health and welfare, resulting in its widespread use in medical and commercial products and healthy food. Recently, favourable functions of RJ on male fertility have been reported in different animals. According to earlier literatures, the level of RJ supplementation in animal diet ranged from 100 to 200 mg/kg. Oral exposure to RJ has been reported to have oestrogenic influences in the adult female rats. Also, RJ may be influential in improvement of pregnancy and lambing rates of ewes. Oral administration of RJ at 100 mg/kg diet before sexual maturity enhanced sexual behaviour and semen quality of male rabbits. Moreover, RJ administration (up to 400 mg/kg diet once weekly) for male rabbits exposed to heat stress can counteract"summer infertility"and improve physiological responses. Furthermore, supplementation of freezing extender media with 0.1 or 3% RJ had a protective influence on cryopreserved and chilled spermatozoa of buffalo and ram respectively. However, the high dose of RJ oral administration (800 mg/kg) by pubescent male rats for 1 month had an undesirable effect on the reproductive system; however, the somewhat unfavourable influences were mitigated by the discontinuation of the administration. This review shows the chemical composition, favourable applications and health benefits of RJand its effects on reproductive aspects, semen quality and in vitro fertilization outcomes which are advantageous for scientists, researchers, nutritionists, physiologists, embryologists, pharmacists, veterinarians, pharmaceutical industries and animal's breeders.

Abstract: 

The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) in addition to quadruple-therapy on Helicobacter pylori eradication, dyspepsia, biochemical-markers, and quality of life in infected patients. In this double-blind placebo-controlled clinical-trial, 51 H. pylori infected patients with functional dyspepsia were randomly assigned to treatment (quadruple-therapy with 2 g/day N. sativa) or placebo groups (quadruple-therapy with 2 g/day placebo) for 8 weeks. Serum levels of interleukin-8 (IL-8), high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde, quality of life, dyspepsia, food-intake, body-weight, and body mass index (BMI) were evaluated at the baseline and at the end of the study. H. pylori eradication was evaluated at the end of the intervention. At the end of the study, H. pylori eradication was more in the N. sativa group compared with the placebo (p = .01).

Abstract Title: 

Acute low-dose bisphenol S exposure affects mouse oocyte quality.

Abstract: 

Bisphenol S (BPS) is widely used to replace the known endocrine disruptor BPA in various products. We evaluated the effect of acute in vivo BPS exposure on oocyte quality, simulating the oral route of exposure via oral gavage. Eight-week-old ICR female mice (N = 15 per experimental group) were exposed to vehicle or BPS1-BPS4 (0.001, 0.1, 10, and 100 ng BPS x g bwday, respectively) for seven days. Oocytes were isolated and matured in vitro. We observed that BPS exposure increased aberrant spindle formation in mature oocytes and induced DNA damage. Moreover, BPS3 significantly increased the chromatin repressive marks 5-methyl cytosine (5meC) and H3K27me2 in immature oocytes. In the BPS2 group, the increase in 5meC occurred during oocyte maturation. Transcriptome analysis revealed differential expression of early embryonic development transcripts in BPS2-exposed oocytes. These findings indicate that the biological effect of BPS is non-monotonic, affecting oocyte quality even at concentrations that are orders of magnitude below those measured in humans.
