In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: To test whether oral L-81 treatment could improve the condition of mice with diabetes and to investigate how L-81 regulates microsomal triglyceride transfer protein (MTP) activity in the liver.', 'Genetically diabetic (db/db) mice were fed on chow supplemented with or without L-81 for 4 wk. The body weight, plasma glucose level, plasma lipid profile, and adipocyte volume of the db/db mice were assessed after treatment. Toxicity of L-81 was also evaluated. To understand the molecular mechanism, HepG2 cells were treated with L-81 and the effects on apolipoprotein B (apoB) secretion and mRNA level of the MTP gene were assessed.', 'Treatment of db/db mice with L-81 significantly reduced and nearly normalized their body weight, hyperphagia and polydipsia. L-81 also markedly decreased the fasting plasma glucose level, improved glucose tolerance, and attenuated the elevated levels of plasma cholesterol and triglyceride. At the effective dosage, little toxicity was observed. Treatment of HepG2 cells with L-81 not only inhibited apoB secretion, but also significantly decreased the mRNA level of the MTP gene. Similar to the action of insulin, L-81 exerted its effect on the MTP promoter.\Question: Does pluronic L-81 ameliorate diabetic symptoms in db/db mice through transcriptional regulation of microsomal triglyceride transfer protein?
L-81 represents a promising candidate in the development of a selective insulin-mimetic molecule and an anti-diabetic agent.

Context: Right ventricular rupture, resulting in serious bleeding, is a life-threatening complication associated with negative-pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier between the heart and the sharp sternal edges has been successfully tested on pigs. In the present article, we demonstrate increased safety in NPWT through the use of the HeartShield device.', 'Six patients were treated with a specially designed device in combination with NPWT. The device consists of a horizontally placed disk covered in foam. The back of the T-shaped device sticks up between the sternal edges and up above skin level. This part of the device is also covered in foam. Drainage is performed through two holes at the top of the device. The device and foam are changed every second to third day, and -120 mm Hg of continuous therapy is used. Six patients were treated with traditional NPWT, serving as control group.', 'No signs of calluslike formation were seen on the right ventricle in the group treated with the HeartShield device. In the conventional NPWT control group, all six patients had calluslike formation (>1 × 2 cm2) on the anterior part of the right ventricle. All patients in the HeartShield group had grade 1 epicardial petechial bleeding (<0.5 cm2) on the right ventricle. In the control group, one patient had grade 1 (<0.5 cm2), three patients had grade 2 (0.5-2.0 cm2), and two patients had grade 3 (>2.0 cm2) epicardial petechial bleeding on the right ventricle. No major bleeding or mortality was observed in either group during the course of the study.\Question: Does the HeartShield device reduce the risk for right ventricular damage in patients with deep sternal wound infection?
The use of the HeartShield device significantly minimizes the contact between the right ventricle and the sternal edges, thereby decreasing the risk for life-threatening complications due to bleeding.

Context: Hepatocyte growth factor/scatter factor (HGF/SF) can sufficiently and independently induce pathophysiological angiogenesis. However, the treatment strategies have mostly been unsuccessful. The present study is the first to evaluate the possible targeting of downstream signals for the inhibition of HGF/SF-induced angiogenesis.', 'In a multichannel scratch assay with human endothelial cells (ECs), HGF/SF induced a strong and prolonged activation of MAPK and cell proliferation that was inhibited by PD98059 and LY294002/wortmannin, selective inhibitors of MAPK and PI3K signaling modules, respectively. Western blotting demonstrated a temporal relation between the activation of the two pathways. Chemical inhibition of the PI3K and MAPK signals inhibited HGF/SF-induced chemoinvasion of ECs in vitro and blocked the HGF/SF-induced neovascularization into a polymer scaffold in vivo, as quantified by vessel counts and the clearance of radioactive 133Xe.\Question: Does targeting of mitogen-activated protein kinases and phosphatidylinositol 3 kinase inhibit hepatocyte growth factor/scatter factor-induced angiogenesis?

These data indicate that MEK and PI3K inhibitors represent a promising approach to the clinical management of pathological conditions characterized by overt HGF/SF-induced angiogenesis.
