The razor clam, Sinonovacula constricta, is an important economic marine shellfish, and its larval development involves obvious morphological and physiological changes. MicroRNA plays a key role in the physiological changes of the organism through regulating targeted mRNA. This study performed miRNA-mRNA sequencing for eight different developmental stages of S. constricta using Illumina sequencing. A total of 2156 miRNAs were obtained, including 2069 known miRNAs and 87 novel miRNAs. In addition, target genes were predicted for key miRNAs differentially expressed between adjacent development samples by integrating the mRNA transcriptome. Further analysis revealed that the differentially expressed genes were enriched in complement activation, alternative pathways, translation, and negative regulation of monocyte molecular protein-1 production. KEGG pathway annotation showed significant enrichment in the regulation of the ribosome, phagosome, tuberculosis and fluid shear stress, and atherosclerosis. Ten mRNAs and ten miRNAs that are related to larval metamorphosis were identified using real-time PCR. Furthermore, the double luciferase experiment validated the negative regulatory relationship between miR-133 and peroxisome proliferator-activated receptor-γ (PPAR-γ). These results indicated that the target genes regulated by these differentially expressed miRNAs may play an important regulatory role in the metamorphosis development of S. constricta.Busulfan (Bu) has been used in combination with fludarabine (Flu; BuFlu) or cyclophosphamide (Cy; BuCy) as conditioning for allogeneic hematopoietic stem cell transplantation (HSCT). This multi-institutional prospective study compared pharmacokinetic (PK) parameters of Bu between BuFlu and BuCy. Plasma Bu concentrations were measured by high-performance liquid chromatography at the first dose of the first and fourth days of intravenous Bu administrations (total of 16 doses of 0.8 mg/kg). Thirty-seven patients were evaluable (BuFlu, N = 18; BuCy, N = 19). The median age was significantly higher in BuFlu. In BuFlu, the median area under the blood concentration-time curve of Bu on the fourth day was 1183 μmol min/L (range 808-1509), which was significantly higher than that on the first day [1095 μmol min/L (range 822-1453), P  less then  0.01]. In contrast, such differences were not observed in BuCy. Consistently, there was a significant decrease in the clearance of Bu on the fourth day as compared with the first day in BuFlu. These results suggest that the PK of Bu was altered during the co-administration of Flu, which was not the case with Cy. A large-scale study is required to evaluate the significance of the differences in the PK of Bu between the conditionings on HSCT outcomes.Recently, progression of disease within 24 months (POD24) has been demonstrated as a strong prognostic indicator in various types of malignant lymphoma. Peripheral T-cell lymphoma (PTCL) has an aggressive course and poor clinical outcomes. In this multicenter retrospective study, 111 consecutively registered patients with newly diagnosed PTCL were analyzed. Of these patients, 72 (64.9%) experienced POD24 (POD24 group), and the other 39 patients (35.1%) were analyzed as the no POD24 group. In the POD24 group, overall survival (OS) was significantly inferior to all patients, and in the no POD24 group, subsequent OS was significantly superior to the POD24 group, although the clinical characteristics between the POD24 group and no POD24 group were not significantly different. Twenty-three patients (20.7%) showed primary refractory disease to first-line therapy, and the prognosis was poor. The International Prognostic Index score and POD24 were identified as independent predictors in multivariate analysis for OS in all patients, and only performance status was an independent prognostic factor for OS in the POD24 group in multivariate analysis. In conclusion, the clinical significance of assessing POD24 in PTCL and the poor prognosis in patients with early disease progression were demonstrated.Thymic lipofibroadenomas are extremely rare; their radiological features have never been reported. We report the first case of a lipofibroadenoma with some largish calcifications mimicking a teratoma. A 28-year-old man had an anterior mediastinal tumor with some calcifications on preoperative computed tomography, which was suspected to be a mature teratoma and resected through robot-assisted thoracic surgery. This tumor had strands of epithelial cells separated by abundant fibrous stroma containing fat cells and was thus diagnosed as a lipofibroadenoma. He was well without any recurrence 6 months postoperatively. Largish calcifications on preoperative computed tomography make distinguishing between teratomas and lipfibroadenomas difficult.
A few studies have described the outcomes of systemic-to-pulmonary artery shunt (SPS) for functional single ventricular heart with extracardiac total anomalous pulmonary venous connection (TAPVC). This study aimed to examine the outcomes of SPS with extracardiac TAPVC and identify the predictors of mortality before bidirectional Glenn operation (BDG).

Medical records of 41 children with single ventricular heart and extracardiac TAPVC who underwent SPS between 1998 and 2019 were reviewed retrospectively. The median age and body weight at SPS were 36days and 3.4kg, respectively. Surgical outcomes and predictors of mortality were investigated.

Four operative deaths (10%) and 10 late deaths (27%) occurred before BDG. Of all the children, 19 underwent BDG at a median of 10months since SPS and eight are waiting for BDG. In the multivariate analysis, preoperative pulmonary venous obstruction (p = 0.01) at initial surgery was most predictive of death before BDG. Selleckchem Ridaforolimus Patients who underwent simultaneous SPS and TAPVC repair were younger, had high preoperative rate of pulmonary venous obstruction, and more deaths before BDG.

Survival outcomes of SPS for SVH with extracardiac TAPVC were improved as a whole due to the increase in knowledge and technique of management SPS. However, the patients who have preoperative pulmonary venous obstruction (PVO) and need SPS and TAPVC repair concomitantly in the early postnatal period have poor outcomes and still challenging. In such a case, staged TAPVC repair and SPS may be beneficial.
