2Blood micronutrient, oxidative stress, and viral load in patients with chronic hepatitis C显示文摘AIM: To assess the extent of micronutrient and oxidative stress in blood and to examine their linkages with viral loads in chronic hepatitis C patients.METHODS: Hepatitis C virus (HCV)-RNA levels were quantified in the serum from 37 previously untreated patients with chronic hepatitis C. The plasma and erythrocyte micronutrients (zinc, selenium, copper, and iron) were estimated, and malondialdehyde (MDA)contents were determined as a marker to detect oxidative stress. Antioxidant enzymes, superoxide dismutase (SOD),glutathione peroxidase (GPX) and glutathione reductase (GR) activities in blood were also measured. The control group contained 31 healthy volunteers.RESULTS: The contents of zinc (Zn), and selenium (Se)in plasma and erythrocytes were significantly lower in hepatitis C patients than in the controls. On the contrary,copper (Cu) levels were significantly higher. Furthermore,plasma and erythrocyte MDA levels, and the SOD and GR activities in erythrocytes significantly increased in hepatitis C patients compared to the controls. However, the plasma GPX activity in patients was markedly lower. Plasma Se (r= -0.730, P<0.05), Cu (r = 0.635), and GPX (r = -0.675)demonstrated correlations with HCV-RNA loads. Significant correlation coefficients were also observed between HCV-RNA levels and erythrocyte Zn (r = -0.403), Se (r = -0.544), Cu (r = 0.701) and MDA (r = 0.629) and GR (r = 0.441).CONCLUSION: The levels of Zn, Se, Cu, and oxidative stress (MDA), as well as related anti-oxidative enzymes (GR and GPX) in blood have important impact on the viral factors in chronic hepatitis C. The distribution of these parameters might be significant biomarkers for HCV.Wang-Sheng Ko Chih-Hung Guo Maw-Sheng Yeh Li-Yun Lin Guoo-Shyng W.

3Mitogenomic phylogeny of the Asian colobine genus Trachypithecus with special focus on Trachypithecus phayrei(Blyth, 1847) and description of a new species显示文摘Trachypithecus,which currently contains 20 species divided into four groups,is the most speciose and geographically dispersed genus among Asian colobines.Despite several morphological and molecular studies,however,its evolutionary history and phylogeography remain poorly understood.Phayre’s langur(Trachypithecus phayrei) is one of the most widespread members of the genus,but details on its actual distribution and intraspecific taxonomy are limited and controversial.Thus,to elucidate the evolutionary history of Trachypithecus and to clarify the intraspecific taxonomy and distribution of T.phayrei,we sequenced 41 mitochondrial genomes from georeferenced fecal samples and museum specimens,including two holotypes.Phylogenetic analyses revealed a robustly supported phylogeny of Trachypithecus,suggesting that the T.pileatus group branched first,followed by the T.francoisi group,and the T.cristatus and T.obscurus groups most recently.The four species groups diverged from each other 4.5-3.1 million years ago(Ma),while speciation events within these groups occurred much more recently(1.6-0.3 Ma).Within T.phayrei,we found three clades that diverged 1.0-0.9 Ma,indicating the existence of three rather than two taxa.Following the phylogenetic species concept and based on genetic,morphological,and ecological differences,we elevate the T.phayrei subspecies to species level,describe a new species from central Myanmar,and refine the distribution of the three taxa.Overall,our study highlights the importance of museum specimens and provides new insights not only into the evolutionary history of T.phayrei but the entire Trachypithecus genus as well.Christian Roos Kristofer MHelgen Roberto Portela Miguez Naw May Lay Thant Ngwe Lwin Aung Ko Lin Aung Lin Khin Mar Yi Paing Soe Zin Mar Hein Margaret Nyein Nyein Myint Tanvir Ahmed Dilip Chetry Melina Urh EGrace Veatch Neil Duncan Pepijn Kamminga Marcus AHChua Lu Yao Christian Matauschek Dirk Meyer Zhi-Jin Liu Ming Li Tilo Nadler Peng-Fei Fan Le Khac Quyet Michael Hofreiter Dietmar Zinner Frank Momberg 2020Zoological Research2020,41,6:5
4Lewis blood genotypes of peptic ulcer and gastric cancer patients in Taiwan显示文摘AIM: The Lewis b (Leb) antigen has been implicated as a possible binding site for attachment of Helicobacter pylori (H pylori)to gastric mucosa. However, studies both supporting and denying this association have been reported in the literature. Differences in secretor (Se)genotype have been suggested as a possible reason for previous discrepancies. Therefore, we investigated the relationship between Le and Se genotypes and H pylori infection rates in people with peptic ulcer or gastric cancer.METHODS: Peripheral blood samples were obtained from 347 patients with endoscopic evidence of peptic ulcer disease (235 cases of duodenal ulcer, 62 of gastric ulcer,and 50 of combined duodenal ulcer/gastric ulcer) and 51patients with gastric cancer on endoscopy. Peripheral blood specimens from 101 unrelated normal volunteers were used as controls. Lewis phenotype was determined using an antibody method, whereas Le and Se genotypes were determined by DNA amplification and restriction enzyme analysis. Gastric or duodenal biopsies taken from patients with endoscopic evidence of peptic ulcer or gastric cancer were cultured for H pylori. Isolates were identified as H pylori by morphology and production of urease and catalase. The H pylori infection status was also evaluated by rapid urease test (CLO test), and urea breath test (13C-UBT). Results of studies were analyzed by chi-square test (taken as significant).RESULTS: H pyloriwas isolated from 83.7% (303/347)of patients with peptic ulcer disease. Statistical analysis did not show any significant difference in Lewis phenotype or genotype between patients with and without H pylori infection. No significant association was found between Lewis genotype and peptic ulcer or gastric cancer.CONCLUSION: Lewis blood genotype or phenotype may not play a role in the pathogenesis of H pyloriinfection.However, bacterial strain differences and the presence of more than one attachment mechanism may limit the value of epidemiological studies in elucidating this matter.Chi-Jung Yei Jan-Gowth Chang Mu-Chin Shih Sheng-Fung Lin Chao-Sung Chang Fu-Tsong Ko Kuang-Yang Lin Ta-Chih Liu 2005World Journal of Gastroenterology2005,11,31:5

9Current status and trends in forest genomics显示文摘Forests are not only the most predominant of the Earth's terrestrial ecosystems,but are also the core supply for essential products for human use.However,global climate change and ongoing population explosion severely threatens the health of the forest ecosystem and aggravtes the deforestation and forest degradation.Forest genomics has great potential of increasing forest productivity and adaptation to the changing climate.In the last two decades,the field of forest genomics has advanced quickly owing to the advent of multiple high-throughput sequencing technologies,single cell RNA-seq,clustered regularly interspaced short palindromic repeats(CRISPR)-mediated genome editing,and spatial transcriptomes,as well as bioinformatics analysis technologies,which have led to the generation of multidimensional,multilayered,and spatiotemporal gene expression data.These technologies,together with basic technologies routinely used in plant biotechnology,enable us to tackle many important or unique issues in forest biology,and provide a panoramic view and an integrative elucidation of molecular regulatory mechanisms underlying phenotypic changes and variations.In this review,we recapitulated the advancement and current status of 12 research branches of forest genomics,and then provided future research directions and focuses for each area.Evidently,a shift from simple biotechnology-based research to advanced and integrative genomics research,and a setup for investigation and interpretation of many spatiotemporal development and differentiation issues in forest genomics have just begun to emerge.Dulal Borthakur Victor Busov Xuan Hieu Cao Qingzhang Du Oliver Gailing Fikret Isik Jae-Heung Ko Chenghao Li Quanzi Li Shihui Niu Guanzheng Qu Thi Ha Giang Vu Xiao-Ru Wang Zhigang Wei Lin Zhang Hairong Wei 2022Forestry Research2022,2,1:2
