Brown SJ, White S, Power N. Tracking undergraduate student achievement in a first-year physiology course using a cluster analysis approach. Adv Physiol Educ 39: 278–282, 2015; doi:10.1152/advan.00076.2015.—A cluster analysis data classification technique was used on assessment scores from 157 undergraduate nursing students who passed 2 successive compulsory courses in human anatomy and physiolo...
The aim of this study was to develop an optimal sustainable forest plantation based on goal programming and Analytic Hierarchy Process (AHP) methods. This study was carried out in Guilan province, north of Iran. First of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological Makhdoum Model by ...
کلون کردن و بیان ژن ha ویروس آنفلوانزای پرندگان تحت تیپ h9n2 در حامل های باکتریایی لاکتوکوکوس لاکتیس
ویروس آنفلوانزای پرندگان تحت تیپ h9n2، یکی از معضلات مهمی است که صنعت طیور ایران با آن روبرو است. یکی از راه کارهای مهم مقابله با آن استفاده از واکسن است ولی خصوصیاتی مانند پر زحمت بودن و تزریقی بودن استفاده از آن را در مزارع طیور مشکل ساخته است. بنابراین جایگزینی آن یا واکسن کارا و مناسب لازم به نظر می رسد. در این مطالعه قسمتی از ha1 و ha2 ژن ha ویروس h9n2، که محل-های آنتی ژنیک ویروس را کد می ...
Wood quality attributes were examined in six stands of slash pine (Pinus elliottii Engelm. var. elliottii) and loblolly pine (P. taeda L.) in the lower Coastal Plain of Georgia and Florida. Several plots comprised each stand, and each plot was divided so that it received three fertilizer treatments: a control treatment with herbaceous weed control at planting and brush control at mid-rotation o...
This study examined in vivo and in vitro colonization by Aggregatibacter actinomycetemcomitans, an organism highly associated with aggressive periodontitis. Thirteen volunteers (5 were A. actinomycetemcomitans positive for buccal epithelial cells [BECs] and teeth, 5 were A. actinomycetemcomitans positive for teeth only, and 3 were A. actinomycetemcomitans-negative controls) had two mandibular s...
Objective: This study aims at evaluating the clinical effects of Platelet Rich Plasma (PRP) and Hyaluronic Acid (HA) as individual treatments for mild to moderate Osteoarthritis (OA) and it also examines the potential synergistic effects of PRP in combination with HA. Research continues to emerge examining the potential therapeutic efficacy of HA and PRP as autologous injectable treatments for ...
در این پژوهش پوششهای نانوکامپوزیتی هیدروکسیآپاتیت-اکسید تیتانیم (HA-TiO2) و هیدروکسیآپاتیت-اکسید تیتانیم- نانولولههای کربنی (HA-TiO2-CNT) توسط فرآیند الکتروفورتیک در ولتاژ 20 ولت و زمان 4 دقیقه بر روی زیرلایهای از جنس فولاد زنگ نزن316L ایجاد شد. به منظور ساخت سوسپانسیون پایدار از ایزوپروپانل به عنوان حلال و از تری اتانول آمین به عنوان پراکندهساز استفاده شد. ریزساختار و توزیع نانوذرات تقو...
OBJECTIVE To determine deformity correction by postural correction and subsequent balloon inflation in acute vertebral compression fractures (OVCFs) and to examine the effect of bone mineral density on deformity correction. METHODS A totol of 50 acute OVCFs received balloon kyphoplasty. Lateral radiographs were taken and analyzed at five different time points : 1) preoperative, 2) after placi...
Tick-borne encephalitis virus (TBEV) causes human epidemics across Eurasia. Clinical manifestations range from inapparent infections and fevers to fatal encephalitis but the factors that determine disease severity are currently undefined. TBEV is characteristically a hemagglutinating (HA) virus; the ability to agglutinate erythrocytes tentatively reflects virion receptor/fusion activity. Howeve...
