    Description: Sequence stratigraphy and coal cycles based on accommodation trends were investigated in the coal-bearing Lower Cretaceous Mannville Group in the Lloydminster heavy oil field, eastern Alberta. The study area is in a low accommodation setting on the cratonic margin of the Western Canada sedimentary basin. Geophysical log correlation of coal seams, shoreface facies, and the identification of incised valleys has produced a sequence-stratigraphic framework for petrographic data from 3 cored and 115 geophysical-logged wells. Maceral analysis, telovitrinite reflectance, and fluorescence measurements were taken from a total of 206 samples. Three terrestrial depositional environments were interpreted from the petrographic data: ombrotrophic mire coal, limnotelmatic mire coal, and carbonaceous shale horizons. Accommodation-based coal (wetting- and drying-upward) cycles represent trends in depositional environment shifts, and these cycles were used to investigate the development and preservation of the coal seams across the study area. The low-accommodation strata are characterized by a high-frequency occurrence of significant surfaces, coal seam splitting, paleosol, and incised-valley development. Three sequence boundary unconformities are identified in only 20 m (66 ft) of strata. Coal cycle correlations illustrate that each coal seam in this study area was not produced by a single peat-accumulation episode but as an amalgamation of a series of depositional events. Complex relations between the Cummings and Lloydminster coal seams are caused by the lateral fragmentation of strata resulting from the removal of sediment by subaerial erosion or periods of nondeposition. Syndepositional faulting of the underlying basement rock changed local accommodation space and increased the complexity of the coal cycle development. This study represents a low-accommodation example from a spectrum of stratigraphic studies that have been used to establish a terrestrial sequence-stratigraphic model. The frequency of changes in coal seam quality is an important control on methane distribution within coalbed methane reservoirs and resource calculations in coal mining. A depositional model based on the coal cycle correlations, as shown by this study, can provide coal quality prediction for coalbed methane exploration, reservoir completions, and coal mining.

    Description: There is much interest in using embryonic stem cells to regenerate tissues and organs. For this approach to succeed, these stem cells or their derivatives must engraft in patients over the long term. Unless a cell transplant is derived from the patient's own cells, however, the cells will be targeted for rejection by the immune system. Although standard methods for suppressing the immune system achieve some success, rejection of the transplant is inevitable. Emerging approaches to address this issue include 're-educating' the immune system to induce tolerance to foreign cells and reducing the immune targeting of the transplant by administering 'self stem cells' instead of foreign cells, but each of these approaches has associated challenges.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chidgey, Ann P -- Layton, Daniel -- Trounson, Alan -- Boyd, Richard L -- England -- Nature. 2008 May 15;453(7193):330-7. doi: 10.1038/nature07041.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monash Immunology and Stem Cell Laboratories, Building 75, STRIP, Monash University, Wellington Road, Clayton 3800, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18480814" target="_blank"〉PubMed〈/a〉

    Description: Endogenous thymic regeneration is a crucial function that allows for renewal of immune competence after stress, infection, or immunodepletion. However, the mechanisms governing this regeneration remain poorly understood. We detail such a mechanism, centered on interleukin-22 (IL-22) and triggered by the depletion of CD4(+)CD8(+) double-positive thymocytes. Intrathymic levels of IL-22 were increased after thymic insult, and thymic recovery was impaired in IL-22-deficient mice. IL-22, which signaled through thymic epithelial cells and promoted their proliferation and survival, was up-regulated by radio-resistant RORgamma(t)(+)CCR6(+)NKp46(-) lymphoid tissue inducer cells after thymic injury in an IL-23-dependent manner. Administration of IL-22 enhanced thymic recovery after total body irradiation. These studies reveal mechanisms of endogenous thymic repair and offer innovative regenerative strategies for improving immune competence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3616391/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3616391/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dudakov, Jarrod A -- Hanash, Alan M -- Jenq, Robert R -- Young, Lauren F -- Ghosh, Arnab -- Singer, Natalie V -- West, Mallory L -- Smith, Odette M -- Holland, Amanda M -- Tsai, Jennifer J -- Boyd, Richard L -- van den Brink, Marcel R M -- AI080455/AI/NIAID NIH HHS/ -- CA107096/CA/NCI NIH HHS/ -- HL069929/HL/NHLBI NIH HHS/ -- HL095075/HL/NHLBI NIH HHS/ -- R01 AI080455/AI/NIAID NIH HHS/ -- R01 CA107096/CA/NCI NIH HHS/ -- R01 HL069929/HL/NHLBI NIH HHS/ -- R01 HL095075/HL/NHLBI NIH HHS/ -- T32 CA009207/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 6;336(6077):91-5. doi: 10.1126/science.1218004.

    Notes: Summary A net reabsorption of fluid was observed in isolated ferret trachea under control conditions. Cholinergic stimulation resulted in net secretion of fluid while atropine blocked this response without any effect on the basal process of fluid reabsorption.

    Notes: [Auszug] THE Chinese chronicle T-Hung-Lian-Kang-Mu records the siege of the city Kai-Fung-Fu by the Monguls in the year A.D. 1232. The defenders, it would appear, had two new weapons at their disposal, both of them depending on the use of gunpowder. The picturesque names of these devices are translated ...
