Over the past decade, we have seen an alarming number of high-profile outbreaks of newly emerging and re-emerging *** outbreaks of avian influenza viruses, Middle East respiratory syndrome coronaviruses, Zika virus and Ebola virus present great threats to global health. Considering the pivotal role of host t-cell immunity in the alleviation of symptoms and the clearance of viruses in patients, there are three issues to be primarily concerned about t-cell immunity when a new virus emerges: first, does the population possess pre-existing t-cells against the new virus through previous infections of genetically relevant viruses; second, does a proper immune response arise in the patients to provide protection through an immunopathogenic effect; lastly, how long can the virus-specific immune memory persist. Herein, we summarize the current updates on the characteristics of human t-cell immunological responses against recently emerged or re-emerged viruses, and emphasize the necessity for timely investigation on the t-cell features of these viral diseases, which may provide beneficial recommendations for clinical diagnosis and vaccine development.

PURPOSE: Bowel function after low anterior resection for rectal cancer with co lonic j-pouch reconstruction is more normal than after conventional straight an astomosis. However, few reports have examined the function of colonic j-pouch r econstruction in the elderly. Good function would obviate the need for colostomy , which is sometimes performed because of concern about fecal incontinence, whic h increases with age. this study evaluated the function of colonic j-pouch reco nstruction in elderly patients aged 75 years or older. MEtHODS: Functional outco me was compared in 20 patients aged 75 years or older (older group) and 27 patie nts aged 60 to 74 years (old group) and 60 patients aged 59 years or younger (yo ung group), 3 years after colonic j-pouch reconstruction, using a functional sc oring system with a 17-item questionnaire (score range, 0 (overall good) to 26 (overall poor)). RESULtS: the functional scores in the three age groups were sat isfactory and similar. Among patients with anastomoses 1 cm to 4 cm from the ana l verge, all 17 categories on the questionnaire in the three age groups were sim ilar. Among patients with anastomoses 5 cm to 8 cm from the anal verge, only the use of laxatives or glycerine enemas was more common in the older group than in the old and young group (90 vs. 38.5 percent and 43.3 percent; P = 0.01). CONCL USIONS: Low anterior resection with colonic j-pouch reconstruction provides exc ellent functional outcome, including continence, for elderly patients. Colonic j -pouch reconstruction is a highly preferable alternative to permanent colostomy in elderly patients undergoing low anterior resection.

We report new petrological data and geochronological measurements of granulites from Vesleknausen in the highest-grade section of the L＆#252;tzow-Holm Complex, part of the Gondwana-assembling collisional orogen in East Antarctica. the locality is dominated by felsic to intermediate orthogneiss （charnockite and minor biotite gneiss）, mafic orthogneiss, and hornblende-pyroxene granulite, with deformed and undeformed dykes of metagranite and felsic pegmatite. Pseudosection analysis of charnockite in the system NCKFMASHtO, supported by geothermometry of mafic orthogneiss, was used to infer peak metamorphic temperatures of 750e850 ？C, approximately 150 ？C lower than those estimated for met-asedimentary gneisses from Rundv？gshetta, 6 km to the northeast. SHRIMP U-Pb analysis of zircons from feldspar-pyroxene gneiss, which corresponds to a partially molten patch around mafic orthogneiss, yielded a Concordia upper intercept ages of 2507.9 ？ 7.4 Ma, corresponding to the time of formation of the magmatic protolith to the orthogneiss. Partial melting during peak metamorphism probably took place between 591 and 548 Ma, as recorded in rims overgrew around magmatic zircon. Our results suggest that Rundv？gshetta-Vesleknausen-Strandnibba region in southwestern L＆#252;tzow-Holm Bay, where orthogneisses are dominant, consists of a single crustal block, possibly formed by ca. 2.5 Ga arc mag-matism. the Neoarchean magmatic terrane was tectonically mingled with other fragments （such as metasedimentary units in northern L＆#252;tzow-Holm Bay） by subduction/collision events during the as-sembly of Gondwana supercontinent, and subsequently underwent w850 ？C granulite-facies meta-morphosed during Neoproterozoic to Cambrian final collisional event.

Nuclear β-decay half-lives are predicted based on an empirical formula and the mass predictions from various nuclear *** is found that the empirical formula can reproduce the nuclearβ-decay half-lives well,especially for short-lived nuclei with t_(1/2)theoretical half-life uncertainties fromβ-decay energies and the parameters of the empirical formula are further *** is found that the uncertainties of the half-lives are relatively large for heavy nuclei and nuclei near the neutron-drip *** nuclei on the r-process path,the uncertainties for those with N=126 are about one order of magnitude,which are much larger than the uncertainties for those with N=50 and ***,theoretical uncertainties from the parameters of the empirical formula are relatively small for the nuclei on the r-process path,which indicates that the empirical formula is very suitable for predicting theβ-decay half-lives in r-process simulations.
