Introduction: Juxtarenal abdominal aortic aneurysms (JRAAAs) are challenging to cure by traditional endovascular aortic repair (EVAR). Due to the inherent disadvantages of the customized fenestrated and/or branched aortic endografts (such as delayed cycles with a risk of aneurysm rupture, unavailable in emergency or confine operations), several off-the-shelf devices have been developed for the treatment of JRAAA. However, these devices being used in clinical trials have been proven to have a non-negligible risk of reintervention and inadequate anatomic applicability.

In this experiment, a total of 264 AA commercial male broilers (21 d old) were assigned to 4 treatment groups with 6 replicates of 11 chickens for a 21-day trial period, the frequency of head-scratching and head-shaking behavior at the initial stage (2, 24, and 72 h) of ammonia exposure were recorded, and the production performance indices and the lung pathological changes after 21 d of ammonia exposure were observed. The correlation analysis was established between head behavior and production performance indices.

Ammonia is one of the harmful pollutants in the atmosphere environment, which has a great threat to human and animal respiratory tract health, but the mechanism of causing diseases is not clear. In this study, broiler lung tissue was used as a model to study the effect of high ammonia on respiratory tract diseases through the relationship between respiratory microflora, NLRP3 inflammasome, and inflammatory factors.

Atherosclerotic diseases may include femoropopliteal artery stenosis or occlusion. Percutaneous transluminal angioplasty (PTA) is an effective and minimally invasive treatment strategy for atherosclerotic femoropopliteal artery stenosis/occlusion disease. Balloon angioplasty is a widely used technique in the management of occlusive disease in almost all arterial segments.

We conducted this study to investigate whether miRNA-26a (miR-26a) has effect on the IRI-induced VEC injury via the AMPK pathway by targeting 6-phosphofructo-2-kinase-fructose-2,6-biphosphatase 3 (PFKFB3). IRI rat models were successfully constructed by an abdominal incision.

Recently, microRNAs (miR) have emerged as regulators of IRI as well as ischemic preconditioning and ischemic postconditioning. Therefore, using rat models, this study aims to explore all of the possible mechanisms that miR-19 exhibits with its relation to the transforming growth factor beta (TGF-β1)/Smad signaling pathway in the lower limb IRI.

Thoracic endovascular aortic repair (TEVAR) in the current era has been chosen as a dominant and minimally invasive treatment for complicated aorta dissection. This study aimed to assess safety and feasibility of TEVAR in acute and chronic type B aortic dissection.Between January 2011 and December 2013, 85 patients with complicated type B aortic dissection undergoing TEVAR were divided into acute aortic dissection (AAD) (n = 60) group and chronic aortic dissection (CAD) group (n = 25).

Methods: From July 1997 to July 2011, 120 consecutive high-surgical-risk patients with AAA who were treated electively using a bifurcated aortic endograft were entered in a registry. There were 96 male and 24 female patients, aged from 52 to 95 years with a mean of 74 years.
Objective: Foam sclerotherapy of ovarian varicocele is a relatively new and promising treatment option for patients with axial reflux. But its usefulness may be limited by low primary occlusion rates. Here a standard technique for catheter-directed foam sclerotherapy was presented to facilitate a precise delivery of foam to its intended site of action so as to potentially improve the occlusion rates.

In order to investigate the effects of acute heat stress and subsequent stress removal on function of hepatic mitochondrial respiration, production of reactive oxygen species (ROS) and lipid peroxidation in broiler chickens, 128 six-week-old broiler chickens were kept in a controlled-environment chamber. The broiler chickens were initially kept at 25 degrees C (relative humidity, RH, 70+/-5%) for 6d and subsequently exposed to 35 degrees C (RH, 70+/-5%) for 3h, then the heat stress was removed and the temperature returned to 25 degrees C (RH, 70+/-5%). Blood and liver samples were obtained before heat exposure and at 0 (at the end of the three-hour heating episode, this group is also abbreviated as the HT group), 1, 2, 4, 8, 12h after the stress was removed.

Chromium picolinate is a popular nutritional supplement whose safety has been questioned because of the potential risk of oxidative DNA damage. To investigate this possibility, a dose-dependent study was performed in piglet hepatocyte cultures in which low (8 microM), medium (200 microM), and high (400 microM) doses of chromium picolinate were tested and compared to untreated controls. After 48 h incubation, there were no significant differences in the levels of intracellular reactive oxygen species, medium lactate dehydrogenase activity, and comet indicators between the three experimental groups and controls (p > 0.
