Promotion of the CoO/TiO Interface on Catalytic Decomposition of Ammonium Perchlorate.

Supports can widely affect or even dominate the catalytic activity and selectivity of nanoparticles because atomic geometry and electronic structures of active sites can be regulated, especially at the interface of nanoparticles and supports. However, the underlying mechanisms of most systems are still not fully understood yet. Herein, we construct the interface of CoO/TiO to boost ammonium perchlorate (AP) catalytic decomposition.

Postmenopausal women with hyperandrogenemia: Three case reports.

Background: Diagnosing hyperandrogenemia in postmenopausal women is very difficult. It occasionally manifests as excessive hair growth or with no clinical manifestations, and is therefore often misdiagnosed or missed altogether. Ovarian steroid cell tumors that cause hyperandrogenemia in women account for approximately 0.

Added value of contrast-enhanced ultrasound (CEUS) in the diagnosis of primary retroperitoneal serous adenocarcinoma: a case report.

Background: Primary retroperitoneal serous adenocarcinoma (PRSA) is a rare malignant disease. Given the rarity of the disease, the imaging features of PRSA are unclear. Contrast-enhanced ultrasound (CEUS) also plays an important role in the evaluation of the differential diagnosis of retroperitoneal lesions.

Uterine mass after caesarean section: a report of two cases.

Background: Caesarean scar pregnancy (CSP) is a rare complication of caesarean delivery and a special type of ectopic pregnancy. Gestational trophoblastic neoplasia (GTN) is an uncommon complication of pregnancy. Early diagnosis of the two diseases is crucial because a delay or misdiagnosis can lead to increased maternal morbidity and mortality.

Prognostic significance of DAPK promoter methylation in lymphoma: A meta-analysis.

We aimed to characterize the clinical significance of epigenetic loss of death-associated protein kinase (DAPK) gene function through promoter methylation in the development and prognosis of lymphoma. PubMed, Web of Science and ProQuest databases were searched for relevant studies. Twelve studies involving 709 patients with lymphoma were identified.

Reduced expression of MTUS1 mRNA is correlated with poor prognosis in bladder cancer.

Mitochondrial tumor suppressor 1 (MTUS1) is a newly identified candidate tumor suppressor gene. Previous studies have demonstrated that the expression status of MTUS1 is altered in several types of tumors. However, its clinical significance for bladder cancer patients remains undetermined.

[Clinical characteristics and surgical treatment for localized Castleman's disease].

Objective: To investigate the clinical characteristics and treatment of localized Castleman's disease (CD), and review the literatures to improve the diagnosis and management of this disease.

Methods: The clinical symptoms, histopathology, CT, MRI findings and results of surgery in 20 patients with localized CD were evaluated retrospectively.

Results: The average age of the patients was 37.

Extraperitoneal laparoscopic adenomectomy for benign prostatic hyperplasia.

Objectives: We assessed the feasibility of extraperitoneal laparoscopic prostatectomy in pilots in China.

Materials And Methods: Extraperitoneal laparoscopic retropubic prostatectomy has been performed in 45 patients with prostatic weight more than 60 g between May 2005 and May 2008. The laparoscopic approach was standard in all cases as follows: creation of a preperitoneal workspace, haemostatic control of lateral venous vesicoprostatic pedicles, transversal anterior incision of the prostate capsule, prostatic adenomectomy and retrieval of the specimen.
