It is not known whether children who are struggling with reading in a non‐dominant language will respond better to a phonological intervention or to one that addresses oral proficiency. Multilingual seven‐to nine‐year‐olds showing reading difficulty in a non‐dominant language, English, were given a three‐week intervention in phonological skills or in language proficiency and were compared with two control groups (one with reading difficulties and one with no reading difficulties) who received a non‐language based intervention. The group receiving the explicit phonological instructions showed significantly better gain in reading and spelling measures than the language proficiency and reading difficulties control group, but did not reach the levels of the noreading‐difficulty group. The phonological intervention was particularly effective for children with the lowest single‐word reading scores. We suggest that the intervention helped to catalyse the fine‐tuning of the phonological domain, making phonological representations optimally available for decoding, phonological manipulations and literacy development. 相似文献

For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on‐going. We hypothesize that three‐dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi‐colored and multi‐material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ~1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi‐colored, multi‐material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.

A comparative analysis was made on the utility of SEVAFILACHEK-stick based immunoassays and commercially available ICT-filariasis
test to detect active infection in different groups of bancroftian filariasis. The SEVAFILACHEK immunoassays were found to
be useful to detect filarial infection in microfilaraemia and in a significant number of clinical filarial cases with acute,
chronic and occult clinical manifestations. In the clinical cases, microfilariae are not usually detected in peripheral circulation.
Employing SEVAFILACHEK assays 6 and 5 of the 7 samples of patients with chronic filarial disease, and 6 and 5 of 6 microfilaraemic
cases gave positivity for filarial IgG antibodies and antigen respectively. Four of the 6 occult filarial samples were positive
for antibodies and antigen. Filarial antigen was detected by ICT-filariasis test in blood samples of all the 6 microfilariaemic
cases, 1 chronic filarial and 2 occult filarial samples. The main advantage of ICT assay is its rapid format and convenience
for field use. 相似文献

Tuberculosis is emerging as a major public health problem in developing and developed world. Early and precise diagnosis is
of prime importance in successful control of infection. Indirect ELISA with penicillinase as marker was developed using purifiedM. tuberculosis excretory-secretory (EST-DE1) antigen for detecting IgG antibodies in pulmonary tuberculosis. The assay System gave a overall sensitivity of 82% for both
smear positive and smear negative pulmonary tuberculosis cases with a specificity of 84%. The positive and negative predictive
values were 75% and 88% respectivaly. Further studies with EST-DE1 antigen revealed that, it contains two of the active antigen fractions of Mtb EST antigen i.e. Mtb EST-4 (56–68 KDa) and
Mtb EST-6 (37–45 KDa), as demonstrated by inhibition ELISA. Reactivity with monoclonal antibodies HGT 3a showed the presence
of 38 KDa molecule in EST-DE1 antigen. 相似文献

Lymphatic filariasis is a mosquito borne parasitic infection and can severely affect the normal working ability of an individual. Currently there is no vaccine available to prevent this infection and the development of a potential vaccine could effectively support the on-going mass drug administration program by World Health Organization (WHO). Filarial parasites have complex mechanisms to modulate the host immune responses against them. The glutathione-S-transferases (GST) are the important enzymes effectively involved to counteract the oxidative free radicals produced by the host. In the present study, we have shown that the mastomys which are fully permissible rodents for Brugia malayi when immunized with Wuchereria bancrofti recombinant GST (rWbGST) could induce 65.5 % in situ cytotoxicity against B. malayi infective (L3) larvae. There was a balanced Th1/Th2 immune response in the vaccinated animals, characterized by higher levels of WbGST-specific IgG1 and IgG2a antibodies and pronounced IFN-γ, IL-10 and IL-4 cytokines production by the spleen cells. 相似文献

Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to indirect informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes direct neuropsychological or academic assessment data to determine treatment efficacy. Documenting "cool" executive-working memory (EWM) and "hot" self-regulation (SR) neuropsychological impairments could aid in differential diagnosis of ADHD subtypes and determining cognitive and academic MPH response. In this study, children aged 6 to 16 with ADHD inattentive type (IT; n = 19) and combined type (n = 33)/hyperactive-impulsive type (n = 4) (CT) participated in double-blind placebo-controlled MPH trials with baseline and randomized placebo, low MPH dose, and high MPH dose conditions. EWM/ SR measures and behavior ratings/classroom observations were rank ordered separately across conditions, with nonparametric randomization tests conducted to determine individual MPH response. Participants were subsequently grouped according to their level of cool EWM and hot SR circuit dysfunction. Robust cognitive and behavioral MPH response was achieved for children with significant baseline EWM/SR impairment, yet response was poor for those with adequate EWM/ SR baseline performance. Even for strong MPH responders, the best dose for neuropsychological functioning was typically lower than the best dose for behavior. Findings offer one possible explanation for why long-term academic MPH treatment gains in ADHD have not been realized. Implications for academic achievement and medication titration practices for children with behaviorally diagnosed ADHD will be discussed. 相似文献

Cyclosporine has been reported to function as an inhibitor of the chymotrypsin like activity of proteasome. We hypothesized
that the administration of an exogenous proteinase inhibitor may affect the activities of the naturally occurring serum anti
proteinases. The aim of this study was to observe the pattern of alteration of serum alpha 2 macroglobulin (AMG), alpha 1-
antitrypsin (AT) and alpha 1-antichymotrypsin (ACT) activities in renal transplant patients receiving the immunosuppressive
drug, cyclosporine. Patients (97) who had received a single renal allograft were inducted into the study. Subjects were on
a twice-daily dosage of cyclosporine capsules. Trough (Co) and two-hour post dose (C 2) cyclosporine levels were regularly
estimated and all patients had stable creatinine levels. In 5 newly transplanted patients, antiproteinase activities were
estimated weekly over a 4-week period as their cyclosporine doses were gradually tapered. Average serum activities of ACT
and AMG in the transplant group were significantly less than in the control group (p<0.002 and p<0.003 respectively). AT and
ACT activities fell gradually over 4 weeks. AMG activities showed a biphasic pattern, initially falling by almost 50% in the
second week, increasing marginally in the third week and decreasing to less than 50% of the activities observed in the first
week. Serum antiproteinase activities of serum alpha 2 macroglobulin (AMG), alpha 1-antitrypsin (AT) and alpha 1-antichymotrypsin
(ACT) were found to be altered in renal transplant patients receiving cyclosporine. 相似文献

Serum cardiac troponin T (cTnT) and CKMB (mass) were analysed in three groups of patients. The first group (n=32) were patients
with acute coronary syndromes including myocardial infarction. The second group (n=35)were patients with hypertension. The
third group (n=24) were patients who had succumbed to non cardiac diseases. In all 3 groups, cardiac troponin T was elevated
when compared with controls (p<0.001). However, CKMB elevation was not significant in all groups. CKMB levels correlated well
with troponin T levels only when CKMB was greater than 50 ng/ml (r=1.00). Small elevations of troponin T identifies minimal
cardiac necrosis and patients can benefit from early invasive therapy. 相似文献

Oligonucleotide primers were synthesised based on the gene sequence of an 18 kDa allergen/antigen ofA. fumigatus isolated from a pathogenic strain. Polymerase chain reaction (PCR) was carried out using the forward and reverse primers
and genomic DNA ofA. fumigatus, A. flavus andA. niger as template. This resulted in a PCR product of 480 bp with onlyA. fumigatus. The absence of PCR product inA. flavus andA. niger with the primers of Asp fl facilitated use of these primers for detection ofA. fumigatus in clinical specimens of patients. The results were compared with microscopy, culture and serology. Application of PCR test
to clinical samples of aspergillosis patients is discussed. 相似文献
