Design of Transverse Brachiation Robot and Motion Control System for Locomotion between Ledges at Different Elevations.

Bio-inspired transverse brachiation robots mimic the movement of human climbers as they traverse along ledges on a vertical wall. The constraints on the locomotion of these robots differ considerably from those of conventional brachiation robots due primarily to the need for robust hand-eye coordination. This paper describes the development of a motion control strategy for a brachiation robot navigating between wall ledges positioned on a level plane or at different elevations.

Enhanced anti-tumor efficacy of aspirin combined with triptolide in cervical cancer cells.

Background: The non-steroidal anti-inflammatory drug (NSAID) aspirin (acetylsalicylic acid) is an inhibitor of cyclooxygenase enzymes. Recent studies have shown that aspirin could be used as an anti-tumor drug. Triptolide, the major compound extracted from the Chinese herb Tripteryglum wilfordii Hook.

Metformin versus metformin plus rosiglitazone in women with polycystic ovary syndrome.

Background: Hyperinsulinemia and insulin resistance are present in the majority of women with polycystic ovary syndrome (PCOS). Both metformin and rosiglitazone can improve the ovulation and endocrine disorders of the patients. How about the combination of the two? It is rarely reported.

Effects of benazepril on cardiac fibrosis in STZ-induced diabetic rats.

Objective: The present study was designed to explore the roles of MMP-2/TIMP-2 in cardiac fibrosis and to study the effects of benazepril, an angiotensin-converting enzyme inhibitor (ACEI) on cardiac remodelling in streptozotocin(STZ)-induced diabetic rats.

Methods And Results: Male Wistar rats were randomly divided into three groups: a normal control group (NC), a diabetes mellitus-untreated group (DM) and a diabetes mellitus benazepril-treated group (DB). Diabetes mellitus was induced in the DM and DB groups by intraperitoneal injection of streptozotocin (60 mg/kg).

A pure nongestational ovarian choriocarcinoma in a 10-year-old girl: case report and literature review.

Nongestational ovarian choriocarcinoma (NGCO) is a rare form of malignancy, which is difficult to diagnose. We present a case of a 10-year-old girl diagnosed with pure nongestational ovarian choriocarcinoma. This patient responded well to conservative surgery and cisplatin-based regimen chemotherapy.

The roles of MMP-2/TIMP-2 in extracellular matrix remodelling in the hearts of STZ-induced diabetic rats.

Objective: The present study was designed to examine the changes of MMP-2/TIMP-2 in the hearts of streptozotocin-induced diabetic rats and gain insight into their roles in extracellular matrix (ECM) remodelling on an experimental animal model of diabetic cardiomyopathy.

Methods And Results: Sixteen male Wistar rats were randomly divided into two groups: normal control and diabetic rats. Diabetes mellitus was induced in rats by streptozotocin injection.

Effects of benazepril on renal function and kidney expression of matrix metalloproteinase-2 and tissue inhibitor of metalloproteinase-2 in diabetic rats.

Background: Excessive deposition of extracellular matrix (ECM) in the kidney is the hallmark of diabetic nephropathy. Increased matrix synthesis has been well documented but the effects of diabetes on degradative pathways, particularly in the in vivo setting. The renal protective effect of these pathways on matrix accumulation has not been fully elucidated.
