BACKGROUND: Patients with multiple injuries or sepsis requiring intensive care treatment invariably develop a catabolic state with resultant loss of lean body mass, for which there are currently no effective treatments. Recovery can take months and mortality is high. We hypothesise that treatment with the orexigenic and anti-inflammatory gastric hormone, ghrelin may attenuate the loss of body mass following critical illness and improve recovery. METHODS: Male Wistar rats received an intraperitoneal injection of the fungal cell wall derivative zymosan to induce a prolonged peritonitis and consequent critical illness...

BACKGROUND: There were many articles about double-barreled fibular flap for mandibular reconstruction. The upper layer bone was suit for implant placement as a new alveolar. The lower layer was necessary for contour. But the accurate relationship between the 2 layers bone was rarely reported. OBJECTIVES: The purpose of this study was twofold: to evaluate the feasibility of the novel design of the double-barreled fibular flap from virtual surgery to actual result; to evaluate the accuracy and results of occlusion-guided double-barreled fibular free flap in mandible reconstruction...

AIMS: Nitroxyl anion (HNO) has recently become an emerging candidate in vascular regulation. NO- is a potent vasodilator of both conduit and small resistance vessels and mediates relaxation in a soluble guanylate cyclase-dependent manner. Interestingly, HNO activates voltage-dependent K+ (K+V) channels, whereas nitric oxide (NO) activates calcium-activated K+ channels. To date, there are few studies investigating the role of HNO in hypertension, and the possible mechanisms, which may be altered during this condition...

BACKGROUND: Hernia meshes exhibit variability in mechanical properties, and their mechanical match to tissue has not been comprehensively studied. We used an innovative imaging model of in vivo strain tracking and ex vivo mechanical analysis to assess effects of mesh properties on repaired abdominal walls in a porcine model. We hypothesized that meshes with dissimilar mechanical properties compared to native tissue would alter abdominal wall mechanics more than better-matched meshes. METHODS: Seven mini-pigs underwent ventral hernia creation and subsequent open repair with one of two heavyweight polypropylene meshes...

Sprague Dawley rats were subjected to acute myocardial infarction (AMI) by permanent ligation of the left anterior descending coronary artery. At the time of AMI, a subcutaneous mini-osmotic pump was implanted and animals were randomized into three groups, according to the intravenous therapy received during the first 72 h: placebo-treated (saline), serelaxin10-treated (SRLX10 = 10 μg/kg/day), or serelaxin30-treated (SRLX30 = 30 μg/kg/day). Treatment with SRLX30 reduced the expression of inflammatory cytokines and chemokines, as well as the infiltration of macrophages, and increased the expression of pro-angiogenic markers and vessel density in the infarcted myocardium after 7 days...

A narrow maxilla with high arched palate characterizes a phenotype of obstructive sleep apnea (OSA) patients that is associated with increased nasal resistance and posterior tongue displacement. Current maxillary expansion techniques for adults are designed to correct dentofacial deformity. We describe distraction osteogenesis maxillary expansion (DOME) tailored to adult patients with OSA with narrow nasal floor and high arched palate without soft tissue redundancy. DOME is performed with placement of maxillary expanders secured by mini-implants along the midpalatal suture...

PURPOSE: The management of chronic ocular hypotony and complicated proliferative vitreoretinopathy-related retinal detachment represents a challenge. Being non-absorbable and non-biodegradable, a silicone oil implant is expected to restore the volume and the intraocular pressure of the globe, as well as to approximate the detached retina. Further advantages could be a long-term tamponade potential, absence of toxicity, and prevention of silicone oil emulsification or anterior chamber oil-prolapse...

INTRODUCTION: Mini implants form a valuable source for absolute anchorage thereby helping in achieving ideal treatment outcome. Stability of the mini implant is one of the important factors affecting the success of mini implants. Thread shape is a critical factor in the engineering design of mini implant, which affects the primary stability. AIM: To evaluate the effects of thread shape on the pull out strength of mini implants. MATERIALS AND METHODS: Mini implants of five different designs in thread shape (reverse buttress, buttress, 75° joint profile with flutes, trapezoidal and trapezoidal fluted) were used with 10 screws in each group...

BACKGROUND: The cumulative amount of iodinated-contrast-medium necessary for EVAR planning, operative procedure and subsequent follow-up is a threat for the onset of end stage renal disease in patients with pre-operative impaired kidney function. Purpose of this study is to describe a mini-invasive approach aimed to minimize the exposure of these patients to iodinated-contrast-medium and the subsequent risk of renal function worsening. METHODS: From 2012 to 2015, all patients with abdominal aortic aneurysm (AAA) at high-surgical risk and fit for standard endovascular repair (simple aortic-iliac anatomy: proximal and distal neck length ≥15mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: pre-operative planning was performed by non-contrast enhanced computed tomography (CT) and duplex-ultrasound (DU); the origin of renal/hypogastric arteries and aortic bifurcation was evaluated and matched with vertebral bone landmarks and the endograft deployed accordingly, using < 20cc of isotonic iodinate-contrast-medium and contrast-enhancement-DU (CEUS)...
