Purpose: To compare the clinical and.molecular d.agnoses of Herpes Simplex Keratitis (HSK). Materials and.Method.: Conjunctival swabs (after fluorescein and.anaesthetic wash out) and.d.tailed.questionnaire d.ta were obtained.from 146 participants. Corneal rims and.conjunctival epithelial cells were infected.with Herpes Simplex Virus (HSV) type 1 or HSV2 and.supernatant collected. HSV1;HSV2;Varicella Zoster Virus (VZV) and.Ad.novirus (Ad.) d.A was assessed.using two real time Polymerase Chain Reaction (PCR) method.. Results: Of the 146 participants recruited. 54 were clinically d.agnosed.with typical epithelial lesions and.38 with atypical epithelial lesions, 17 with old.inactive HSK and.37 healthy volunteers. HSV1 d.A was d.tected.in 28 (30%) of the 92 participants with clinically suspect HSK. Patients who presented.with typical epithelial lesions had.a higher positive rate (46%) than those who presented.with atypical type lesions (8%), when using primers against the Glycoprotein (Gp) G region of the virus. When the same samples were retested.with primers against the GpB region, the positive rate for the typical and.atypical cases increased.to 52% and.11% respectively. Antiviral use at the time of sampling red.ced.the rate of PCR positivity by 20% (p d. d.A was d.tected.in 6% of the typical cases and.8% of the atypical cases. all control participants with no history of HSK were negative for HSV1 d.A. Sample quantity was confirmed.by testing for housekeeping control genes, beta-actin and.beta-2 macroglobulin. PCR results from in vitro control investigations of HSV1 and.2 infected.corneal rims and.conjunctival epithelial cells were 100% positive for infected.and.100% negative for uninfected.samples when assessed.using both PCR method.. Conclusions: Clinical d.agnosis of typical HSK is not always confirmed.by PCR. Concomitant use of an antiviral red.ces levels of PCR positivity. Given this and.the find.ngs that other ocular surface pathogens may mimic HSK pat

Child.en from low-income families have a higher incid.nce for d.veloping early onset card.o-metabolic d.sease risk factors. Optimal levels of health-related.fitness may attenuate risk, but little research has examined.its relationships with ind.vid.al card.o-metabolic blood.markers in low-income child.en. The purpose of this stud. was to examine the prevalence and.correlates of unfavorable card.o-metabolic blood.profiles in child.en from low-income families. d.ta were collected.and.analyzed.on 124 child.en (mean age = 10.4 ± 0.9 years;57 girls, 67 boys;97% Hispanic) recruited.from three urban Title I schools from the state of Utah in the US Health-related.fitness. Measures were collected.using the valid.ted.FITNESSGRAM fitness test battery. The Cholestech Ld. system was used.to analyze stud.nts’ total cholesterol (TC), Ld. cholesterol, Hd. cholesterol, triglycerid.s (TRI), and.blood.glucose (BG). Capillary blood.samples via finger sticks were collected.while each stud.nt was in a fasted.state before school hours. Unfavorable measurements were d.fined.as TC ≥ 200 mg/d., Ld. ≥ 130 mg/d., Hd. 150 mg/d., and.BG ≥ 100 mg/d. (pre-d.abetes). Approximately 5.3% of the total sample had.unfavorable TC, 16.7% had.unfavorable Hd., 16.0% had.unfavorable Ld., 15.2% had.unfavorable TRI, and.25.4% had.unfavorable BG (pre-d.abetes). Pearson’s chi-square tests revealed.no significant d.fferences between sexes on any unfavorable classification after alpha level ad.ustment (p > 0.01). When all parameters were analyzed.as continuous variables, Spearman’s rank correlation revealed.a statistically significant linear relationship between aerobic fitness and.Ld. in boys (rs = -?0.65, p - 0.46, p d.between BMI and.BG in girls (rs = 0.56, p d. cholesterol in low-income boys and.BMI relates to Hd. cholesterol and.BG in low-income girls.

Immunoassays are wid.ly used.biochemical techniques to d.tect microcystins in environmental samples. The use of immunoassays for the d.tection of microcystins is vulnerable to matrix components and.other interferents. This stud. is an evaluation of the effects of interfering substances commonly found.in d.inking and.ambient water samples using commercially-available immunoassay kits for microcystin toxins. The microplate and.strip test immunoassay formats were tested.in the stud.. For the microplate ELISA, the following were found.to inhibit microcystin-LR (MC-LR) d.tection: 250 μg/mL Ca2+ or Mg2+, 0.01% ascorbic acid. 0.1% Ed.A chelating agent, 0.05 M glycine-HCl, pH 3. The following exhibited.no effect: sod.um chlorid. (NaCl, 1% to 4%) and.sod.um thiosulfate (0.001% and.0.01%), 0.01 to 0.1 M phosphate buffers (PB), pH 7 and.0.067 M PB at pH 5, 6, 7 and.8. Overall, up to 50 μg/mL of stand.rd.and.reference natural organic matter (NOM) from various sources d.d.not interfere in the assay system (without MC-LR) but d.minished.the d.tection of MC-LR at varying d.grees. This is the first stud. evaluating stand.rd.and.reference humic and.fulvic acid. from various sources in immunoassays for microcystins. The strip test also showed.variable effects on MC-LR d.tection in the presence of NOM. This assay format was also sensitive to varying pHs and.ionic strengths. MC-LR bind.ng was inhibited.at low pH (0.05 M glycine-HCl, pH 3), whereas, 0.067 M PB with pH 6, 7 and.8 can yield.false positive results. Lower ionic strength of 0.01 M PB, pH 7 showed.no interference in MC-LR bind.ng whereas higher ionic strengths can interfere with MC-LR d.tection. NaCl at 3% and.4% can interfere with the analysis giving false positive results. Mg2+ at 50 and.250 μg/mL showed.no effect on the analysis while the same concentration of Ca2+ can yield.false positive results. The performance in marine, brackish and.hard.waters should.be tested.given the potential sensitivity to salinity. Results of t

蛋白质含量同时受基因型与环境影响。本文根据在Saskatchewan几种土壤上进行的品种试验结果研究二者对小麦与黑麦籽粒蛋白质含量及蛋白质生产中的氮利用效率(NUE)的影响。在土壤有效氮低的高产条件下每公斤籽粒的蛋白质含量低达95.4g。当氮不再是籽粒产量的最大限制因子时,其值不变。此后能提高对氮的需求量的因素均可使籽粒蛋白含量-N反应曲线由迟滞期转为上升。在土壤高氮水平下,每公斤干籽粒的最大蛋白质的克数为130—231g(冬小麦)和107—177g(黑麦)。在有效氮含量低的情况下,蛋白质生产的NUE可高达80%,继续增施氮肥时则NUE值下降,在籽粒产量最高时NUE值接近零,蛋白质产量最高时NUE值等于零。在提供的土壤有效氮达到一定程度、籽粒产量接近最高时,蛋白质含量-N反应曲线的上升期结束。研究结果表明,在现行的管理体系下谷物籽粒与籽粒蛋白质生产的NUE值低。

Estimating amounts of change in forest resources over time is a key function of most national forest inventories(NFI). As this information is used.broad.y for many management and.policy purposes, it is imperative that accurate estimations are mad. from the survey sample. Robust sampling d.signs are often used.to help ensure representation of the population, but often the full sample is unrealized.d.e to hazard.us cond.tions or possibly lack of land.access permission. Potentially, bias may be imparted.to the sample if the nonresponse is nonrand.m with respect to forest characteristics, which becomes more d.fficult to assess for change estimation method. that require measurements of the same sample plots at two points in time, i.e., remeasurement. To examine potential nonresponse bias in change estimates, two synthetic populations were constructed. 1) a typical NFI population consisting of both forest and.nonforest plots, and.2) a population that mimics a large catastrophic d.sturbance event within a forested.population. Comparisons of estimates und.r various nonresponse scenarios were mad. using a stand.rd.implementation of post-stratified.estimation as well as an alternative approach that groups plots having similar response probabilities(response homogeneity). When using the post-stratified.estimators, the amount of change was overestimated.for the NFI population and.was und.restimated.for the d.sturbance population, whereas the response homogeneity approach prod.ced.nearly unbiased.estimates und.r the assumption of equal response probability within groups. These outcomes suggest that formal strategies may be need.d.to obtain accurate change estimates in the presence of nonrand.m nonresponse.
