Methods: We retrospectively enrolled 420 consecutive patients that underwent BAE for hemoptysis control in our hospital from September 2011 to May 2019. The clinical characteristics, preprocedural CTA findings, BAE procedural findings, and follow-up outcomes were collected.

Long-Term Exercise on Response Inhibition and Cortical Connectivity in Parkinson's Disease: Design and Implementation of a Randomized Controlled Clinical Trial.

Motor symptom disorders in patients with Parkinson disease (PD) are closely related to reduced inhibitory ability. Although exercise has been shown to improve this ability in patients with PD, its effects on proactive and reactive inhibition have not been determined. Most previous studies of inhibitory control disorder in people with PD have been behavioral, and little attention has been paid to functional cortical connectivity.

Efficacy and safety of docetaxel and prednisolone chemotherapy in very elderly men with metastatic castration-resistant prostate cancer (mCRPC) in real world: a single institute experience.

Background: Prostate cancer is the most common type of malignancy in elderly men. Although elderly patients are commonly encountered in clinical practice, few studies have focused on the value of chemotherapy in elderly patients. In this study, we reviewed the use of docetaxel with prednisolone in elderly men (aged ≥80 years) with metastatic castration-resistant prostate cancer (mCRPC) at Ningbo First Hospital with a focus on efficacy and toxicity.

Modulation of hand motor skill performance induced by motor practice combined with matched or mismatched hand posture motor imagery.

Motor imagery (MI), the mental rehearsal of a movement without muscle activation, combined with motor practice (MP) improves the performance of athletes and promotes rehabilitation of motor function among patients with brain injury. The actual hand posture influences the mental simulation of hand movements such that the ability of MI to affect corticospinal excitability is enhanced when the actual hand posture is consistent with the imagined movement of the hand. However, how MP combined with matched or mismatched hand posture MI modulates hand motor skill performance and the underlying neural mechanisms remain unclear.

Twining Poly(polyoxometalate) Chains into Nanoropes.

Organic polymers and inorganic clusters belong to two different disciplines and have completely different properties and structures. When a cluster is attached to the backbone of a polymer as a pendant, the resultant hybrid polymers (polyclusters) exhibit unique behaviours totally different from those of conventional polymers owing to the nanoscale size of the cluster and its particular interactions. Herein, the aggregation of a poly(polyoxometalate)-a polynorbornene backbone with inorganic polyoxometalate cluster pendants-upon addition of a non-solvent to its dilute solution is reported.

[Synthesis and identification of artificial antigen of spinosin].

Immunogenic antigen (spinosin-BSA) and coating antigen (spinosin-OVA) of spinosin were synthesized by sodium periodate oxidation method. UV scanning analysis method showed that these two spinosins were successfully conjugated with carrier protein and the coupling ratio was 17 and 13.7, respectively.

Expertise-Level-Dependent Functionally Plastic Changes During Motor Imagery in Basketball Players.

The aim of the present study is to examine plastic changes in relevant brain areas during motor imagery with increasing expertise level. Subjects (novices, intermediate and elite players) performed motor imagery of basketball throws under two experimental conditions (with-ball and without-ball).

Identification of significant biomarkers and pathways associated with gastric carcinogenesis by whole genome-wide expression profiling analysis.

The incidence of gastric cancer (GC) is extremely high in East Asia. GC is also one of the most common and lethal forms of cancer from a global perspective. However, to date, we have not been able to determine one or several genes as biomarkers in the diagnosis of GC and have also been unable to identify the genes which are important in the therapy of GC.

Identification of Genes Involved in the Responses of Tangor × to Drought Stress.

Drought is the major abiotic stress with adverse effects on citrus, decreasing the agronomical yield and influencing the fruit quality. In this study, cDNA-amplified fragment length polymorphism (cDNA-AFLP) technique was used to investigate the transcriptional profile changes and identify drought-responsive genes in "Amakusa" tangor × , a hybrid citrus sensitive to water stress. The 255 out of 6,245 transcript-derived fragments (TDFs) displayed altered expression patterns including (A) induction, (B) repression, (C) upregulation, and (D) downregulation.

Human T-cell lymphotropic virus type 1 and its oncogenesis.

Human T-cell lymphotropic virus type 1 (HTLV-1) is the etiologic agent of adult T-cell leukemia/lymphoma (ATL), a rapidly progressing clonal malignancy of CD4+ T lymphocytes. Exploring the host-HTLV-1 interactions and the molecular mechanisms underlying HTLV-1-mediated tumorigenesis is critical for developing efficient therapies against the viral infection and associated leukemia/lymphoma. It has been demonstrated to date that several HTLV-1 proteins play key roles in the cellular transformation and immortalization of infected T lymphocytes.

Targeted sequencing identifies a novel SH2D1A pathogenic variant in a Chinese family: Carrier screening and prenatal genetic testing.

X-linked lymphoproliferative disease type 1 (XLP1) is a rare primary immunodeficiency characterized by a clinical triad consisting of severe EBV-induced hemophagocytic lymphohistiocytosis, B-cell lymphoma, and dysgammaglobulinemia. Mutations in SH2D1A gene have been revealed as the cause of XLP1. In this study, a pregnant woman with recurrence history of birthing immunodeficiency was screened for pathogenic variant because the proband sample was unavailable.
