AbstractPolymerase chain reaction (PCR) diagnosis of thalassemia usually relies on using genomic DNA. Preparing the genomic DNA can lead to sample-to-sample contamination. This report was aimed to establish the PCR protocol using whole-blood for detecting mutations of α- and β-globin genes causing the thalassemia syndrome. First, the PCR facilitators, betaine and bovine serum albumin (BSA), were tested, simultaneously with an adjustment of PCR thermal cycler and of whole-blood volume. Thereafter, the established whole-blood PCR was applied for detecting, in both known and unknown samples, the HBA1 Southeast Asian (–?–SEA) (NG_000006.1: g.26264_45564del19301) deletion, Hb Constant Spring (Hb CS, HBA2: c.427T>C, αCSα), codon 17 (A>T) (HBB: c.52A>T), codons 41/42 (–TTCT) (HBB: c.126_129delCTTT) deletion, –28 (A>G) (HBB: c.-78A>G) and codon 26 (G>A) (Hb E or HBB: c.79G>A). It was shown that the whole-blood PCR worked successfully in 9.0% (w/v) betaine, with 1?μL of EDTA whole blood and with addition of 10 heat-cool steps (3?min. at 94?°C, followed by 3?min. at 55?°C) prior to the typical thermal cycles for the mutations. The capability of the new whole-blood PCR was similar to that of the typical DNA-based PCR. Therefore, the newly established whole-blood PCR could be performed for PCR diagnosis of thalassemia. Using this platform, sample-to-sample contamination should be eliminated. 相似文献

The adenomatoid odontogenic tumor (AOT) is a benign (hamartomatous), noninvasive lesion with slow but progressive growth. A rare subvariant of the extrafollicular type of AOT may mimic periapical disease radiographically. We report on a 15-year-old girl with a periapical radiolucent lesion affecting teeth 7 and 8 initially suspicious of periapical disease, although clinical findings seemed to indicate a nonendodontic lesion. An exploratory surgical approach was chosen, and the final diagnosis of the removed noncystic tissue mass was microscopically confirmed to be an AOT. 相似文献

The objective of this study was to determine the spectrum of radiographic findings, frequency, and type of injuries in tsunami
victims. From December 2004 to May 2005, all tsunami victims admitted to our hospital were retrospectively identified by a
search of medical records. Patients who received radiologic examinations were reviewed for their radiographic findings. The
authors identified 225 tsunami victims. One hundred eight victims received radiologic evaluations on admission that included
350 plain radiographs, 19 ultrasound exams, 18 computed tomography (CT) scans and 3 magnetic resonance imaging (MRI) scans.
Overall positivity rate was 48% (187/390). Most common trauma involved musculoskeleton (102/187, 54.5%). Retained foreign
bodies in soft tissues, pneumonia/aspiration, and tsunami sinusitis were found in 22, 28, and 31 patients (9.8, 12.4, and
13.8%), respectively. These were unique findings in tsunami trauma. Imaging played an important role in detection of these
abnormalities. 相似文献

The chromosome organization among 15 wild diploid Coffea species and cultivated tetraploid C. arabica was determined by fluorochrome banding (CMA, DAPI) and double fluorescence in-situ hybridization (FISH) of 5S and 18S rDNA
achieved on the same chromosome plates. Two to five chromosome pairs (plus one putative chromosome B) are marked. Overall,
there are two SAT-chromosome pairs for East African species and one for the Malagasy and the West and Central African species.
18S rDNA loci are telomeric and strongly marked the SAT-chromosome pairs. Generally, only one pericentromeric 5S rDNA locus
characterized East African species, while an additional minor locus co-localized with the 18S rDNA-SAT locus for the Malagasy
species and West and Central African species. A combination of rDNA FISH plus CMA and DAPI banding patterns enables identification
of almost all the species, even those for which the genetic or botanical status is still being discussed. C. arabica clearly appears to be an allotetraploid species, including one genome from East Africa and one from West and Central Africa.
However, since the minor 5S rDNA-SAT locus present in West/Central African genomes is not detected, two evolutionary hypotheses
could be put forward for C. arabica. Considering only the diploid species, global trends are obvious in rDNA signal patterns, genome size variations, and geographic
distribution of the species, but there are no clear evolutionary trends. However, complex interactions between these factors
and environmental growing conditions exist, which have resulted in loss and gain of rDNA loci and probably also in copy repeat
number variations in each rDNA family. 相似文献

Introduction
The use of dentin preconditioning techniques in regenerative endodontic procedures is currently promising. Several growth factors have been detected on dentin after ultrasonic irrigation with EDTA. This study aimed to evaluate the effects of dynamic irrigation with different solution regimens on apical papilla cell (APC) attachment in an ex vivo immature tooth model.Methods
Various dynamic irrigation techniques, needle irrigation (NI), NI with EndoActivator, and NI with passive ultrasonic irrigation, were used with different solution regimens, normal saline solution (NSS), EDTA, and chlorhexidine digluconate followed by EDTA, in enlarged root canal models where calcium hydroxide–medicated dentin slices were inserted. The initial number of attached fibronectin-positive APCs was counted. Dentin surface morphology was also inspected by using scanning electron microscopy.Results
The number of APCs was significantly greater in the dynamic irrigation groups than in the control group (P < .001). Greater APC numbers were observed in the groups in which NSS was used than in those in which EDTA or chlorhexidine digluconate/EDTA was used, when using the same techniques (P < .001). Cell numbers were similar at all levels of the root canals; however, in the ultrasonically supplemented group irrigated with NSS, the number of attached cells was significantly increased at the middle and apical levels (P < .05).Conclusions
The use of dynamic irrigation techniques in an immature tooth model definitely promoted APC attachment to calcium hydroxide–medicated dentin. Furthermore, when NSS was used as a final irrigant, the number of attached cells was significantly increased. 相似文献8.
High-flow priapism is a very rare condition in children. The most common cause is perineal trauma, which is a major cause of arterio-cavernosal fistula. A few pediatric patients have high-flow priapism without an obvious cause. There are many therapeutic modalities for this condition, depending on the etiology. We report a case of idiopathic high-flow priapism in a 6-year-old boy who underwent repeated superselective embolization. 相似文献
