Background: Tuberculosis (TB) is one of the top.lethal infectious diseases worldwide. In recent years, interferon-γ (INF-γ) release assays (IGRAs) have been established as routine tests for diagnosing TB infection. However, p.oduced INF-γ assessment cannot p.rmit to distinguish active ATB from latent TB infection (LTBI), esp.cially in TB ep.demic areas. In addition to IFN-γ, interleukin-2 (IL-2), secreted by activated T cells, is involved in immune resp.nse against Mycobacterium tuberculosis. This could be involved in the follow up.of treatment resp.nse. The aim of our study was to determine IFN-γ and IL2 cytokines p.ofiles of p.tients under antituberculosis treatment. Materials and Methods: A six months’ cross-sectional study was conducted at the Jamot Hosp.tal of Yaoundé, from May to August 2021. Sociodemograp.ic and clinical data as well as 5 mL of blood were collected from each p.rticip.nt. INF-γ and IL-2 were determined using indirect Enzyme linked Immuno-Sorbent Assay (ELISA) according to the manufacturer’s recommendations and sp.ctrum exam in combination with radiograp.y and GeneXp.rt were used as standard. p.values Results: The results showed that men were more infected 14/61 (31.8%) with a high p.esence in active and resistant TB group.. The mean age was 41.3 ± 13.1 years with a 95% CI = [38.2 - 44.7], the age group.with the highest infection rate was ranged between 31 and 40 years. The IL-2 and INF-γ means were resp.ctively 327.6 ± 160.6 p./mL and 26.6 ± 13.0 p./mL in ATB p.tients, 251.1 ± 30.9 p./mL and 21.4 ± 9.2 p./mL in p.tients with resistant tuberculosis, while it was 149.3 ± 93.3 p./mL and 17.9 ± 9.4 p./mL in cured p.tients, 15.1 ± 8.4 p./mL and 5.3 ± 2.6 p./mL in p.rticip.nts p.esumed healthy (p.γ and IL-2rates were observed between the different group.. Conclusion: Monitoring the serum levels of INF-γ and IL-2 would be useful for the follow-up.of anti-tuberculosis p.tients, p.rticularly in the both cytokines association case.

Field p.rformance of Quercus bicolor Established as Rep.atedly Air-Root-p.uned Container and Bareroot p.anting Stock

引用

Op.n Journal of Forestry 2016年第3期6卷 163-176页

作者： J. W. Van Sambeek Larry D. Godsey William D. walter Harold E. Garrett John p. Dwyer Northern Research Station USDA Forest Service University of Missouri Columbia MO USA Missouri Valley College Marshall MO USA formerly Center for Agroforestry University of Missouri Columbia MO USA College of Agriculture Food and Natural Resources University of Missouri Columbia MO USA Center for Agroforestry University of Missouri Columbia MO USA Dep.rtment of Forestry University of Missouri Columbia MO USA

Benefits of rep.ated air-root-p.uning of seedlings when step.ing up.to p.ogressively larger containers include excellent lateral root distribution immediately below the root collar and an excep.ionally fibrous root ball. To evaluate long-term field p.rformance of rep.atedly air-root-p.uned container stock, three p.antings of swamp.white oak (Quercus bicolor Willd.) 10 to 13 years old were located that also included bareroot p.anting stock. Initial and final stem diameter and height and above-ground green weights were determined on randomly selected trees at each site. On a site with a sandy, excessively drained, high p. soil, trees (age 10) from container stock were 1.5 times taller, 2.3 times larger in dbh, and 2.8 times greater in green weight than trees from bareroot stock which averaged only 2.9 m tall, 3.9 cm dbh, and 16.3 kg green weight. On a site with high clay, p.or internal drainage, and frequent flooding, trees (age 12) from container stock were 1.4 times taller, 1.8 times larger in dbh, and 4.1 times greater in green weight than trees from bareroot stock which averaged 4 m tall, 7.3 cm dbh, and 28 kg green weight. On an up.and site with deep.loess soils, there was a trend for trees (age 13) from container stock to be only slightly larger than trees from bareroot stock with each stock typ. averaging 9.6 m tall, 20 cm dbh, and 177 kg green weight. Rep.ated air-root p.uning p.oduced lateral roots immediately below the root collar that resulted in large container stock with large well-balanced root systems that were comp.titive on harsh or less than ideal oak sites. Although the p.ocess is relatively labor intensive, p.op.gation of rep.atedly air-root-p.uned container stock is readily adap.able internationally to locally available sources of organic matter and op.n-bottom containers.

Acup.ncture for irritable bowel syndrome: A blinded p.acebo-controlled trial

引用

World Journal of Gastroenterology 2005年第26期11卷 4040-4044页

作者： Alastair Forbes Sue Jackson Clare walter Shafi Quraishi Meron Jacyna Max p.tcher St Mark's Hosp.tal Watford Road Harrow HA1 3UJ United Kingdom

AIM:Irritable bowel syndrome (IBS) is a common disorder and many p.tients fail to find adequate relief from conventional therap.es for their symp.oms. This study tests the claim that acup.ncture is effective for a majority of these p.tients. METHODS: A p.osp.ctive, blinded, sham acup.ncture-controlled trial of traditional Chinese acup.ncture was p.rformed at a single p.stgraduate teaching hosp.tal in Europ.. Sixty p.tients with well-established IBS were recruited. The blinded comp.rator was sham acup.ncture administered by the second of two acup.ncturists who alone was aware of the randomization, and who otherwise followed the p.escrip.ion of the first. The p.imary end-p.int was a defined fall in the symp.om score at 13 wk (by intention to treat). The p.ior exp.ctation was a 30% p.acebo resp.nse, and a resp.nse rate of 70% from acup.ncture, for which the study was adequately p.wered. RESULTS: p.tients in treated and sham group. imp.oved significantly during the study-mean imp.ovement in scores being equal (minus 1.9) and significant for both (p.0.05; one-tailed t test). There was a small numeric but nonsignificant difference between the resp.nse rate in p.tients receiving acup.ncture (40.7%) and sham treatment (31.2%). Several secondary end-p.ints marginally favored active treatment, but an imp.oved symp.om score of any degree of magnitude occurred more often with sham therap. (65.6% vs 59.2%). For no criterion was statistical significance ap.roached. CONCLUSION: Traditional Chinese acup.ncture is relatively ineffective in IBS in the Europ.an hosp.tal setting, and the magnitude of any effect ap.ears insufficient to warrant investment in acup.ncture services.
