Nonalcoholic fatty liver disease(NAFLD) is one of the most common liver diseases and its prevalence is likely to reach epidemic *** to the"two-stage hypothesis"proposed for the pathophysiology of NAFLD,insulin resistance,oxidative stress and pro-inflammatory cytokines are among the key promoters of the disease. Here,ginger has been hypothesized to prevent NAFLD or blunt its progression via several mechanisms,such as sensitizing insulin effects,activating peroxisome proliferator-activated receptorγwhich induces adiponectin and down-regulates pro-inflammatory cytokines,changing the balance between adiponectin and tumor necrosis factor-αin favor of adiponectin,promoting considerable antioxidant effects and antidyslipidemic properties,and reducing hepatic triglyceride content which can prevent *** aforementioned mechanisms imply that ginger possesses interesting potentials for serving as a natural supplement for the prevention and treatment of ***,conducting trials to explore its benefits in clinical practice is greatly recommended.

Objective: To estimate the prevalence of antibiotic resistance of Neisseria species in Iran. Methods: A systematic and electronic search using relevant keywords in major national and international databases was performed until 6th July, 2018 in order to find studies reporting the prevalence of antibiotic resistance of Neisseria species in Iran. Results: A total of nine studies were found to be eligible based on predefined inclusion and exclusion criteria. Our analysis indicated that the prevalence of Neisseria gonorrhoeae resistance to different antibiotics was as follows: 66.9% to penicillin, 59.1% to ciprofloxacin, 11.1% to ceftriaxone, 21.6% to spectinomycin, 13.8% to cefixime, 82.4% to co-trimoxazole, 52.7% to tetracycline, 29.9% to gentamicin, 87.5% to ampicillin, 11.1% to azithromycin, 2.2% to chloramphenicol, 50.1% to cefepime and 50.0% to vancomycin. Antimicrobial resistance rates of Neisseria meningitidis was as follows: 30.0% to penicillin, 33.3% to amoxicillin, 33.3% to cephalexin, 55.6% to ampicillin and 0.0% to ciprofloxacin, ceftriaxone, cefotaxime, amikacin, co-trimoxazole, gentamicin, kanamycin, chloramphenicol and ceftizoxime. Conclusion: Neisseria gonorrhoeae and Neisseria meningitidis isolates of Iran show resistance to different types of antibiotics. Therefore, care should be exercised for the use of penicillin, ciprofloxacin, co-trimoxazole, tetracycline, gentamicin, ampicillin, cefepime and vancomycin for gonococcal infections, and also with respect to the use of penicillin, amoxicillin, ampicillin and cephalexin for meningococcal infections in Iran.

Neurodegenerative diseases(NDs)are a growing health problem associated with a high burden due to destructive and longterm clinical *** aggregations of misfolded proteins are the most common pathological hallmark of many late-onset NDs called proteinopathies including Parkinson’s disease(PD),Alzheimer’s disease(AD),tauopathies,amyotrophic lateral sclerosis(ALS),and polyglutamine(polyQ)expansion diseases such as Huntington’s disease(HD)and various spinocerebellar ataxias(SCA)such as SCA3(Renna et al.,2010).Misfolded proteins can be generated by posttranslational conjugation(e.g.,hyperphosphorylated tau in AD),or endoproteolytic cleavage(e.g.,amyloidβpeptides)or genetic mutations in specific proteins(such as HTT in HD,α-synuclein in PD,PrPC in prion disease and SOD1 and TDP-43 in ALS)leading to the formation of oligomers.

Epicuticular waxes have vital roles in the growth and development of plants and in defense. Conifers have a considerable amount of waxes on their cones and *** we characterized the n-alkane composition of Iranian conifers, including Juniperus oblonga, J. foetidissima, ***, J. communis subsp. hemisphaerica, J. excelsa,Cupressus sempervirens, Platycladus orientalis from Cupressaceae and Taxus baccata from Taxaceae for the first time using GC-FID analyses. In the waxes, 25 n-alkane homologs with chain lengths ranging from C7 to C32 were identified. Short-chain n-alkanes were dominant in almost all samples with some exceptions. Complementary studies to elucidate complete wax constituents of Iranian conifers and n-alkane distribution pattern as a function of geographical and bioclimatic variables are recommended.

Objective： To investigate the effectiveness of curcumin, a natural polyphenolic compound with antioxidant and anti-inflammatory activities, on the frequency of symptoms of anxiety and depression in obese individuals. Methods： In this double blind, cross-over trial, 30 obese subjects were randomized to receive either curcumin （1 g/day） or placebo for a period of 30 days. Following a wash-out interval of 2 weeks, each subject was crossed over to the alternative regimen for a further 30 days. Severity of anxiety and depression was assessed at baseline and at weeks 4, 6 and 10 of the trial using the Beck Anxiety Inventory （BAI） and Beck Depression Inventory （BDI） scales, respectively. Results： Mean BAI score was found to be significantly reduced following curcumin therapy （P=0.03）. However, curcumin supplementation did not exert any significant impact on BDI scores （P=0.7）. Conclusion： Curcumin has a potential anti-anxiety effect in individuals with obesity.
