BACKGROUND: White adipose tissue (WAT) is a complex, diffuse, multifunctional organ which contains adipocytes, and a large proportion of fat, but also other cell types, active in defense, regeneration and signalling functions. Studies with adipocytes often require their isolation from WAT by breaking up the matrix of collagen fibres; however, it is unclear to what extent adipocyte number in primary cultures correlates with their number in intact WAT, since recovery and viability are often unknown...

Two hundred and ninety-four pigs were used to assess the effect of two ingredients (Lupinus albus (albus lupins) or a combination of calcium chloride and sodium tri-polyphosphate (mineral salts)) on growth performance, body composition and objective meat quality of pigs immunized against gonadotrophin releasing factor (immunocastrates) and entire male pigs in the late finishing phase. Pigs fed mineral salts ate less feed than those fed the control diet with no effect on growth rate (p > 0.05), backfat (p > 0...

REVIEW
Lena M Napolitano
Exsanguinating torso hemorrhage is a leading killer of trauma patients. The most appropriate means of hemorrhage control must be used. Trauma surgeons should have expertise with all approaches for prompt hemorrhage control [laparotomy, thoracotomy, resuscitative endovascular balloon occlusion of the aorta (REBOA), and resuscitative thoracotomy]. REBOA is an exciting adjunct for hemorrhage control as it can be deployed quickly and placed percutaneously. Balloon inflation can vary dependent on patient physiology...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

BACKGROUND: N-acetylcysteine (NAC) is an antioxidant with direct and indirect antioxidant actions used in the clinical setting. Oxidative stress is known to play a pivotal role in the intestinal ischemia reperfusion (IIR). Therefore, we studied the effect of different pretreatment regimens with NAC on the IIR injury in rats. MATERIALS AND METHODS: Thirty-five male Wistar rats were randomly assigned to five groups. In group sham, only laparotomy was performed. Group control underwent IIR without NAC...

The G protein-coupled receptor 30 (GPR30) is a transmembrane estrogen receptor that binds to estrogen, and has been confirmed to have an important role in testicular cell proliferation and development. The main objective of this study was to examine GPR30 gene expression and localization in the testis and epididymis of sheep at different developmental stages. Testes, including the epididymis, were collected from Polled Dorset x Mongolian cross rams at one (n=4; wt), three (n=4; wt), six (n=4; wt), nine (n=4; wt) and 12 (n=4; wt) months of age...

BACKGROUND: Applying manual pressure after hemorrhage is intuitive, cost-free, and logistically-simple. When direct abdominal-pelvic compression fails, clinicians can attempt indirect proximal-external-aortic-compression (PEAC), while expediting transfer and definitive rescue. This study quantifies the sustainability of simulated bi-manual PEAC both immediately on scene and during subsequent ambulance transfer. The goal is to understand when bi-manual PEAC might be clinically-useful, and when to prioritize compression-devices or endovascular-occlusion...

Synthetic cannabinoids (SCs) have become an increasing issue in forensic toxicology. Controlled human studies evaluating pharmacokinetic data of SCs are lacking and only few animal studies have been published. Thus, an interpretation of analytical results found in intoxicated or poisoned individuals is difficult. Therefore, the distribution of two selected SCs, namely 4-ethylnaphthalen-1-yl-(1-pentylindol-3-yl)methanone (JWH-210) and 2-(4-methoxyphenyl)-1-(1-pentyl-indol-3-yl)methanone (RCS-4) as well as ∆9-tetrahydrocannabinol (THC) as reference were examined in pigs...

Fresh turkey meat color is determined by many factors that include muscle fiber type composition and heme protein concentrations. These factors either are affected by or influence biochemical events occurring postmortem. Deviations in the processing environment also can result in aberrant fresh meat quality and may ultimately change the quality characteristics of further processed products. Our objective was to describe the underlying cause and significance of the two-toning color defect in fresh turkey breast...

BACKGROUND Non-compressible torso hemorrhage continues to be the leading cause of preventable death in trauma patients. Recent case series report that resuscitative endovascular balloon occlusion of the aorta (REBOA) in the trauma population is a technically feasible method to manage the patients with exsanguinating hemorrhage. On the other hand, it seems that REBOA is being widely promoted prematurely. Complications due to REBOA haven't been reported much in the literature, and they could have been underestimated...

Primary aortoduodenal fistula (ADF) is a rare but morbid diagnosis. Here, we present the case of a patient with a primary ADF that resulted in mortality. Despite multiple attempts at radiographic and endoscopic diagnosis, the fistula did not declare itself until the patient exsanguinated. Given the morbidity associated with ADF and the imperfection of associated diagnostic studies, a high index of suspicion is required to make a timely diagnosis.

BACKGROUND: The purpose of massive transfusion protocols (MTPs) is to provide large quantities of blood products rapidly to exsanguinating patients. The expected rates of blood product transfusion and wastage in this setting have not been defined. This study was undertaken to assess the transfusion and wastage rates for bleeding patients requiring emergency issue of blood components at three American Level I trauma centers. STUDY DESIGN AND METHODS: Three hospitals participated, all of which are Level I trauma centers that have MTPs in place where uncrossmatched red blood cells (RBCs) can be ordered with or without platelets (PLTs), plasma, and cryoprecipitate...

INTRODUCTION: Exsanguinating pelvic fractures are still associated with a significant mortality rate of 28-60%. Extraperitoneal pelvic packing (EPP) has been proposed as an optimal method of early haemorrhage control. The aim of this study was to determine the effect of EPP compared with angioembolization as a primary intervention for patients with exsanguinating pelvic fracture. METHOD: A prospective observational trial was performed at Westmead Hospital between September 2011 and May 2014...

The adipocyte-type fatty acid-binding protein (A-FABP) is considered a candidate gene for fat metabolism; thus, it affects fat deposition in chickens. The present study was designed to examine the polymorphism and mRNA abundance of the A-FABP gene with intramuscular fat (IMF) in the pectoralis muscles (PM) and leg muscles (LM) of Three-yellow Chicken (TYC) and Hetian-black Chicken (HTBC). In total, 60 TYCs and 60 HTBCs were sacrificed using exsanguination at market age. The IMF contents of the PM and LM in the HTBC were significantly higher than those in the TYC...

Although there have been reports of carotid artery pseudoaneurysm formation after adenoidectomy and/or tonsillectomy secondary to iatrogenic injury, there are no case reports of successful endovascular reconstruction of the injured artery in the pediatric population. In most pediatric cases, the internal carotid artery (ICA) is sacrificed. The authors report on a 6-year-old girl who presented with odynophagia, left-sided Horner's syndrome, hematemesis, and severe anemia 6 months after a tonsillectomy. On examination she was found to have a pulsatile mass along the left posterior lateral oropharynx, and imaging demonstrated a dissection of the extracranial left ICA and an associated pseudoaneurysm...
