Canada’s boreal forest represents an important contributor of the world’s wood supply industry. However,maintaining or increasing productivity of the boreal forest may be challenging in areas dominated by forested peatlands. Moreover, sustainable management of these forests must also consider other important aspects of the forest ecosystem such as biodiversity and carbon sequestration. To address these concerns, ecosystem-based management has been implemented in some Canadian jurisdictions, such as in regions where a large portion of the boreal forest is dominated by forested peatlands. The objectives of this paper are(1) to summarize our current understanding of how natural disturbances influence stand dynamics and biodiversity in forested peatlands, and(2) to review the main differences between natural and managed forest stands with respect to soil properties, stand productivity, understory plant communities. We also discuss how even-age management regime succeeds or fails to preserve old forests and how this loss affects both forest structure and habitat diversity at the landscape *** conclude by showing how, in boreal forested peatlands, forest management could contribute to carbon sequestration and mitigate projected climate change.

The elastic thickness parameter was estimated using the mobile correlation technique between the observed isostatic disturbance and the gravity disturbance calculated through direct gravimetric modeling. We computed the vertical flexure value of the crust for a specific elastic thickness using a given topographic dataset. The gravity disturbance due to the topography was determined after the calculation. A grid of values for the elastic thickness parameter was generated. Then, a moving correlation was performed between the observed gravity data(representing actual surface data) and the calculated data from the forward modeling. The optimum elastic thickness of the particular point corresponded to the highest correlation coefficient. The methodology was tested on synthetic data and showed that the synthetic depth closely matched the original depth, including the elastic thickness value. To validate the results, the described procedure was applied to a real dataset from the Barreirinhas Basin, situated in the northeastern region of Brazil. The results show that the obtained crustal depth is highly correlated with the depth from known models. Additionally, we noted that the elastic thickness behaves as expected, decreasing from the continent towards the ocean. Based on the results, this method has the potential to be employed as a direct estimate of crustal depth and elastic thickness for any region.

To assess the prevalence of a panel of serologic markers that reflect gut barrier dysfunction in a mixed cohort of pediatric and adult primary sclerosing cholangitis (pSC) patients. METHODSSera of 67 pSC patients [median age (range): 32 (5-79) years, concomitant IBD: 67% and cirrhosis: 20%] were assayed for the presence of antibodies against to F-actin (AAA IgA/IgG) and gliadin (AGA IgA/IgG)] and for serum level of intestinal fatty acid-binding protein (I-FABp) by ELISA. Markers of lipopolysaccharide (LpS) exposure [LpS binding protein (LBp)] and various anti-microbial antibodies [anti-OMp plus IgA and endotoxin core IgA antibody (EndoCAb)] were also determined. poor disease outcome was defined as orthotopic liver transplantation and/or liver-related death during the follow-up [median: 99 (14-106) mo]. One hundred and fifty-three healthy subjects (HCONT) and 172 ulcerative colitis (UC) patients were the controls. rESULTSA total of 28.4%, 28.0%, 9% and 20.9% of pSC patients were positive for AAA IgA, AAA IgG, AGA IgA and AGA IgG, respectively. Frequencies of AAA IgA and AAA IgG (p r both) and AGA IgG (p = 0.01, for both) but not AGA IgA were significantly higher compared to both of the HCONT and the UC groups. In survival analysis, AAA IgA-positivity was revealed as an independent predictor of poor disease outcome after adjusting either for the presence of cirrhosis [Hr = 5.15 (1.27-20.86), p = 0.022 or for the Mayo risk score (Hr = 4.24 (0.99-18.21), p = 0.052]. AAA IgA-positivity was significantly associated with higher frequency of anti-microbial antibodies (p r EndoCab IgA and p = 0.012 for anti-OMp plus IgA) and higher level of the enterocyte damage marker (median I-FABpAAA IgA posvsneg: 365 vs 166 pg/mL, p = 0.011), but not with serum LBp level. CONCLUSIONpresence of IgA type AAA identified pSC patients with progressive disease. Moreover, it is associated with enhanced mucosal immune response to various micr

Background Following on from an earlier study published in 2008 about left pulmonary artery(LpA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LpA to right pulmonary artery(rpA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LpA:rpA diameters(pA ratio orpar)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LpA/rpA diameters,and par were compared between survivors and *** value of par for optimizing the prognostic value of pA diameter data in CDH were analyzed with receiver operating characteristic(rOC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** par for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean par for non-survivors was not affected by surgical *** of survivors were:LpA≥2 mm(n=52 of 54;mean par=0.866±0.146)and rpA≥3mm(n=46 of 54;mean par=0.857±0.152).Non-survivors with similar LpA and rpA diameters to survivors had significantly lower mean *** curve cut-off for par was *** with high par(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low par(p=0.0244 and p=0.0485,respectively)and subjects with high par stabilized significantly earlier than subjects with low par(1.71±0.68 days vs 3.20±0.87 days)(ppar would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.
