| 1 | Gut bless you:The microbiota-gut-brain axis in irritable bowel syndrome显示文摘Irritable bowel syndrome(IBS)is a common clinical label for medically unexplained gastrointestinal symptoms,recently described as a disturbance of the microbiota-gut-brain axis.Despite decades of research,the pathophysiology of this highly heterogeneous disorder remains elusive.However,a dramatic change in the understanding of the underlying pathophysiological mechanisms surfaced when the importance of gut microbiota protruded the scientific picture.Are we getting any closer to understanding IBS’etiology,or are we drowning in unspecific,conflicting data because we possess limited tools to unravel the cluster of secrets our gut microbiota is concealing?In this comprehensive review we are discussing some of the major important features of IBS and their interaction with gut microbiota,clinical microbiota-altering treatment such as the low FODMAP diet and fecal microbiota transplantation,neuroimaging and methods in microbiota analyses,and current and future challenges with big data analysis in IBS. | Eline Margrete Randulff Hillestad Aina van der Meeren Bharat Halandur Nagaraja Ben RenéBjørsvik Noman Haleem Alfonso Benitez-Paez Yolanda Sanz Trygve Hausken Gülen Arslan Lied Arvid Lundervold Birgitte Berentsen | 2022 | World Journal of Gastroenterology2022,28,4: | 15 |
| 2 | Species diversity, regeneration and dominance as influenced by canopy gaps and their characteristics in tropical evergreen forests of Western Ghats, India显示文摘Canopy gaps play a significant role in maintaining structure and composition of tropical forests. This study was carried out in tropical evergreen forests of central Western Ghats in India to understand the influence of canopy gap size and the relationship of gap regime attributes to diversity measures and regeneration. The average gap size in the study area was found to be 396 m2 and around half of gaps were 4–8 years old. Gaps created by natural single tree fall were smaller in size but significantly higher in number. Diversity and regeneration of woody species were compared with canopy gaps and intact vegetation. Species richness and diversity was higher in gaps than in intact vegetation. Macaranga peltata, a shade intolerant species dominated gaps while intact vegetation was dominated by shade tolerant Kingiodendron pinnatum.Gap size significantly influenced species diversity and regeneration. Gap area and age were significantly and negatively correlated with diversity measures but positively correlated with regeneration. Among all the attributes of gaps, regeneration was significantly positively correlated with light intensity. Gaps maintained species diversity and favored regeneration of woody species. In addition to gap size and age, other gap ecological attributes also affected species diversity and regeneration. | Guddappa Mahalingappa Devagiri Anil Kumar Khaple Siddagangaiah Mohan Puttanaik Venkateshamurthy Sanjay Tomar Arkalgud Nagaraja Arunkumar Geeta Joshi | 2016 | Journal of Forestry Research2016,27,4: | 9 |
| 3 | Autologous mobilized peripheral blood CD34^+ cell infusion in non-viral decompensated liver cirrhosis显示文摘AIM: To study the effect of mobilized peripheral blood autologous CD34 positive(CD34+) cell infusion in patients with non-viral decompensated cirrhosis.METHODS: Cirrhotic patients of non-viral etiology were divided into 2 groups based on their willingness to be listed for deceased donor liver transplant(DDLT)(control, n = 23) or to receive autologous CD34+ cell infusion through the hepatic artery(study group, n= 22). Patients in the study group were admitted to hospital and received granulocyte colony stimulating factor injections 520 μg/d for 3 consecutive days to mobilize CD34+ cells from the bone marrow. On day 4,leukapheresis was done and CD34+ cells were isolated using CliniMAC magnetic cell sorter. The isolated CD34+ cells were infused into the hepatic artery under radiological guidance. The patients were discharged within 48 h. The control group received standard of care treatment for liver cirrhosis and were worked up for DDLT as per protocol of the institute. Both groups were followed up every week for 4 wk and then every month for 3 mo.RESULTS: In the control and the study group, the cause of cirrhosis was cryptogenic in 18(78.2%) and16(72.72%) and alcohol related in 5(21.7%) and6(27.27%), respectively. The mean day 3 cell count(cells/μL) was 27.00 ± 20.43 with a viability of 81.84± 11.99%. and purity of 80%-90%. Primary end point analysis revealed that at 4 wk, the mean serum albumin in the study group increased significantly(2.83± 0.36 vs 2.43 ± 0.42, P = 0.001) when compared with controls. This improvement in albumin was,however, not sustained at 3 mo. However, at the end of3 mo there was a statistically significant improvement in serum creatinine in the study group(0.96 ± 0.33 vs 1.42 ± 0.70, P = 0.01) which translated into a significant improvement in the Model for End-Stage Liver Disease score(15.75 ± 5.13 vs 19.94 ± 6.68,P = 0.04). On statistical analysis of secondary end points, the transplant free survival at the end of 1 mo and 3 mo did not show any significant difference(P =0.60) when compared to the control group. There was no improvement in aspartate transaminase, alanine transaminase, and bilirubin at any point in the study population. There was no mortality benefit in the study group. The procedure was safe with no procedural or treatment related complications.CONCLUSION: Autologous CD 34+ cell infusion is safe and effectively improves liver function in the short term and may serve as a bridge to liver transplantation. | Mithun Sharma Padaki Nagaraja Rao Mitnala Sasikala Mamata Reddy Kuncharam Chimpa Reddy Vardaraj Gokak BPSS Raju Jagdeesh R Singh Piyal Nag D Nageshwar Reddy | 2015 | World Journal of Gastroenterology2015,21,23: | 9 |
| 4 | Pooled genetic analysis in ultrasound measured non-alcoholic fatty liver disease in Indian subjects:A pilot study显示文摘AIM: To investigate genetic susceptibility in Indian subjects with non-alcoholic fatty liver disease(NAFLD) by performing a pooled genetic study.METHODS: Study subjects(n = 306) were recruited and categorized into NAFLD and control groups based on ultrasound findings of fatty infiltration. Of the 306 individuals, 156 individuals had fatty infiltration and thus comprised the NAFLD group. One hundred and fifty(n = 150) individuals were normal, without fatty infiltration of the liver, comprising the control group. Blood samples, demographic and anthropometric data from the individuals were collected after obtaining informed consent. Anthropometric data, blood glucose, lipids and liver function tests were estimated using standard methods. Genome wide association stud-ies done to date on NAFLD were identified, 19 single nucleotide polymorphisms(SNPs) were selected from these studies that were reported to be significantly associated with NAFLD and genotyping was performed on the Sequenom platform. Student's t test for continuous variables and χ2 test was applied to variant carriers from both groups. Required corrections were applied as multiple testing was done.RESULTS The mean age of the control group was 39.78 ± 10.83 and the NAFLD group was 36.63 ± 8.20 years. The waist circumference of males and females in the control and NAFLD groups were 80.13 ± 10.35; 81.77 ± 13.65 and 94.09 ± 10.53; 92.53 ± 8.27 respectively. The mean triglyceride and alanine transaminase(ALT) levels in the control and NAFLD groups were 135.18 ± 7.77; 25.39 ± 14.73 and 184.40 ± 84.31; 110.20 ± 67.05 respectively. When χ2 test was applied to the number of individuals carrying the variant risk alleles between the control and NAFLD group, a significant association was seen between rs738409 of the patatin-like phospholipase domain containing 3(PNPLA3) gene(P = 0.001), rs2073080 of the PARVB gene(P = 0.02), rs2143571 of SAMM50 gene(P = 0.05) and rs6487679 of the pregnancy zone protein(PZP) gene(P = 0.01) with the disease. Variant single nucleotide polymorphisms(SNPs) in NCAN and PNPLA3 gene were associated with higher levels of ALT, whereas variant SNPs in APOC3, PNPLA3, EFCAB4 B and COL13A1 were associated with high triglyceride levels. Apart from the above associations, rs2073080, rs343062 and rs6591182 were significantly associated with high BMI; rs2854117 and rs738409 with high triglyceride levels; and rs2073080, rs2143571, rs2228603, rs6487679 and rs738409 with high ALT levels.CONCLUSION: Pooled genetic analysis revealed an association of SNPs in PNPLA3, PARVB, SAMM50 and PZP genes with NAFLD. SNPs in NCAN and PNPLA3gene were associated with higher levels of ALT,whereas variant SNPs in APOC3, PNPLA3, EFCAB4 B and COL13A1 were associated with high triglyceride levels. | Vishnubhotla Venkata Ravi Kanth Mitnala Sasikala Padaki Nagaraja Rao Urmila Steffie Avanthi Kalashikam Rajender Rao Duvvuru Nageshwar Reddy | 2014 | World Journal of Hepatology2014,6,6: | 6 |
| 5 | Evidence-based assessment of proton-pump inhibitors in Helicobacter pylori eradication: A systematic review显示文摘Peptic ulcer disease continues to be issue especially due to its high prevalence in the developing world.Helicobacter pylori(H.pylori)infection associated duodenal ulcers should undergo eradication therapy.There are many regimens offered for H.pylori eradication which include triple,quadruple,or sequential therapy regimens.The central aim of this systematic review is to evaluate the evidence for H.pylori therapy from a meta-analytical outlook.The consequence of the dose,type of proton-pump inhibitor,and the length of the treatment will be debated.The most important risk factor for eradication failure is resistance to clarithromycin and metronidazole. | Vinayak Nagaraja Guy D Eslick | 2014 | World Journal of Gastroenterology2014,20,40: | 3 |
| 6 | Genetics of non-alcoholic fatty liver disease: From susceptibility and nutrient interactions to management显示文摘Genetics plays an important role in determining the susceptibility of an individual to develop a disease. Complex, multi factorial diseases of modern day(diabetes, cardiovascular disease, hypertension and obesity) are a result of disparity between the type of food consumed and genes, suggesting that food which does not match the host genes is probably one of the major reasons for developing life style diseases. Non-alcoholic fatty liver is becoming a global epidemic leading to substantial morbidity. While various genotyping approaches such as whole exome sequencing using next generation sequencers and genome wide association studies have identified susceptibility loci for non-alcoholic fatty liver disease(NAFLD) including variants in patatin-like phospholipase domain containing 3 and transmembrane 6 superfamily member 2 genes apart from others; nutrient based studies emphasized on a combination of vitamin D, E and omega-3 fatty acids to manage fatty liver disease. However majority of the studies were conducted independent of each other and very few studies explored the interactions between the genetic susceptibility and nutrient interactions. Identifying such interactions will aid in optimizing the nutrition tailor made to an individual's genetic makeup, thereby aiding in delaying the onset of the disease and its progression. The present topic focuses on studies that identified the genetic susceptibility for NAFLD, nutritional recommendations, and their interactions for better management of NAFLD. | Vishnubhotla Venkata Ravi Kanth Mitnala Sasikala Mithun Sharma Padaki Nagaraja Rao Duvvuru Nageshwar Reddy | 2016 | World Journal of Hepatology2016,8,20: | 3 |
