During the process of bloodfeeding by Anopheles stephensi, mammalian latent transforming growth factor beta1 (TGF-beta1) is ingested and activated rapidly in the mosquito midgut. Activation may involve heme and nitric oxide (NO), agents released in the midgut during blood digestion and catalysis of L-arginine oxidation by A. stephensi NO synthase (AsNOS). Active TGF-beta1 persists in the mosquito midgut to extended times postingestion and is recognized by mosquito cells as a cytokine. In a manner analogous to the regulation of vertebrate inducible NO synthase and malaria parasite (Plasmodium) infection in mammals by TGF-beta1, TGF-beta1 regulates AsNOS expression and Plasmodium development in A. stephensi. Together, these observations indicate that, through conserved immunological cross talk, mammalian and mosquito immune systems interface with each other to influence the cycle of Plasmodium development. 相似文献

Background
Several studies have reported the clinical outcomes of medial ulnar collateral ligament (MUCL) reconstruction of the elbow joint in throwing athletes, including the rate of return to sports. However, little has been known about the imaging outcomes after MUCL reconstruction. The aim of this study is to report the clinical and imaging outcomes after MUCL reconstruction using figure of eight fashion in the elite and professional baseball players.Methods
This study included 17 baseball players, who underwent MUCL reconstruction between July 2007 and May 2010. The average follow-up period was 48.6 months. Imaging assessment consisted of preoperative plain and stress radiographs, magnetic resonance imaging, and postoperative serial ultrasonography. The clinical assessments were composed of visual analogue scale (VAS) for pain, range of motion, and the Conway scale.Results
The mean VAS score was 6.4 (range, 3 to 8) preoperatively and 2.2 (range, 0 to 4) postoperatively (p < 0.05). There were nine players (53%) classified as excellent who returned to sports at the same or higher level compared to preinjury. Serial ultrasonography revealed well-maintained grafts at 3 and 12 months in all of the players. Five out of 17 players showed decreased echogenecity in the common flexor tendon at 3 months, which was considered as remaining tissue swelling and resolved completely at 12 months.Conclusions
All grafts are well-maintained until 12-months based on the ultrasonographic findings, although only 53% of the players returned to preinjury level. 相似文献5.
Between October 1991 and December 1998, 19 patients (12 males and 7 females) with refractory (six patients) or recurrent (13 patients) AML were treated with a combination chemotherapy of cytarabine given by continuous infusion over 24-h at a rate of 1 upward arrow g/m2 per day for 5 days along with idarubicin (12 upward arrow mg/m2 per day x 3) and etoposide (150 mg /m(2) per day x 3). Median age of the patients was 28 years (range, 15--61). Seven (37%) of 19 patients achieved complete remission (CR) with median CR duration of 6.7 months (range, 2.5--61.4+). Two patients are surviving for long term (50.1 and 62.6 months). Myelosuppression associated with chemotherapy was severe. Median recovery time to ANC over 500/microl was 28 days (range, 25--59). A significant proportion of patients experienced grade III-VI non-hematologic toxicities including nausea/vomiting (32%), liver function abnormality (32%), and diarrhea (16%). No central nervous system (CNS) toxicity was observed. Our study showed that the administration of cytarabine at a dose of 1 g/m(2) per day by continuous intravenous infusion for 5 days along with idarubicin and etoposide was feasible. Further studies are necessary to elucidate optimum dose and schedule of cytarabine in a setting of refractory or relapsed acute myeloid leukemia (AML). 相似文献

A patient had a trisomy for the distal portion of the third chromosome. The major clinical features were failure to thrive, profound mental retardation, dysmorphic head shape, a short nose, anteverted nares, long eyelashes, synophrys, characteristic mouth, and short stature. The similarities between the clinical picture and the Cornelia de Lange syndrome are very striking. 相似文献

This pilot study tested the effect of cognitive behavioral therapy (CBT) on parent-reported autism symptoms. Nineteen children
with autism spectrum disorders and an anxiety disorder (7–11 years old) were randomly assigned to 16 sessions of CBT or a
waitlist condition. The CBT program emphasized in vivo exposure supported by parent training and school consultation to promote
social communication and emotion regulation skills. Parents completed a standardized autism symptom checklist at baseline
and posttreatment/postwaitlist and 3-month follow-up assessments. CBT outperformed the waitlist condition at posttreatment/postwaitlist
on total parent-reported autism symptoms (Cohen’s d effect size = .77). Treatment gains were maintained at 3-month follow-up. Further investigation of this intervention modality
with larger samples and broader outcome measures appears to be indicated. 相似文献

ObjectiveWhile balanced crystalloid (BC) could be a relevant fluid regimen with buffer system compared with normal saline (NS), there have been no studies on the optimal fluid for surgery of an unruptured intracranial aneurysm (UIA). This study aimed to compare the effects of fluid regimens between NS and BC on the metabolic and clinical outcomes of patients who underwent surgery for UIA. MethodsThis study was designed as a propensity score matched retrospective comparative study and included adult patients who underwent UIA clipping. Patient groups were categorized as NS and BC groups based on the types of pre-operative fluid and the amount of fluid administered during surgery. The primary outcomes were defined as electrolyte imbalance and acidosis immediately after surgery. The secondary outcomes were the length of stay in the intensive care unit (ICU) and duration from the end of the operation to extubation. ResultsA total of 586 patients were enrolled in this study, with each of 293 patients assigned to the NS and BC groups, respectively. Immediately after surgery, serum chloride levels were significantly higher in the NS group. Compared to the NS group, the BC group had lower incidence rates of acidemia (6.5% vs. 11.6%, p=0.043) and metabolic acidosis (0.7% vs. 4.4%, p=0.007). As compared to NS group, BC group had significantly shorter duration from the end of the operation to extubation (250±824 vs. 122±372 minutes, p=0.016) and length of stay in ICU (1.37±1.11 vs. 1.12±0.61 days, p=0.001). Throughout multivariable analysis, use of BC was found to be significant factor for favorable post-operative results. ConclusionThis study showed that the patients who received BC during UIA clipping had lower incidence of metabolic acidosis, earlier extubation and shorter ICU stay compared to those who received NS. Therefore, using BC as a peri-operative fluid can be recommended for patients who undergo surgery for UIA. 相似文献

An improved technique for exposing a lymph vessel prior to cannulation is introduced. This involves one clean incision and minimal dissection. Utilizing this technique, a vessel can be exposed within a minute. Damage to the skin and subcutaneous tissue is minimal. Leaking and procedure failures are rare. Fast healing occurs due to minimal incision length and trauma. 相似文献

The 1D wire TaS3 exhibits metallic behavior at room temperature but changes into a semiconductor below the Peierls transition temperature (Tp), near 210 K. Using the 3ω method, we measured the thermal conductivity of TaS3 as a function of temperature. Electrons dominate the heat conduction of a metal. The Wiedemann–Franz law states that the thermal conductivity of a metal is proportional to the electrical conductivity σ with a proportional coefficient of L0, known as the Lorenz number—that is, . Our characterization of the thermal conductivity of metallic TaS3 reveals that, at a given temperature T, the thermal conductivity κ is much higher than the value estimated in the Wiedemann–Franz (W-F) law. The thermal conductivity of metallic TaS3 was approximately 12 times larger than predicted by W-F law, implying . This result implies the possibility of an existing heat conduction path that the Sommerfeld theory cannot account for. 相似文献
