A rare case of fat embolism syndrome secondary to abdominal liposuction and gluteal fat infiltration.

Fat embolism syndrome (FES) is a rare, life-threatening condition habitually associated with traumatic events such as fractures and, less commonly, burns, liposuction and bone marrow harvesting and transplant [ 1]. The biochemical theory for this condition suggests that fat droplets embolize and convert into fatty acids, eventually leading to toxic injury and inflammation, which results in increased vascular permeability, edema and hemorrhage [ 2]. FES may have an asymptomatic interval lasting 12-72 hours after the insult; however, in some cases, signs have also been seen intraoperatively.

Ultrashort-segment Hirschsprung disease in a 4-year-old female.

Hirschsprung disease (HSCR) is characterized by the absence of neuronal ganglion cells in a distal portion of the intestinal tract [1]. In 1691, Frederick Ruysch described the disease as congenital megacolon. HSCR-associated congenital anomalies have been reported in 5-32% of affected patients [2].

Nontraumatic chylothorax secondary to lymphoma and filariasis.

Chylothorax is characterized by extravasation of chyle into the pleural space resulting from thoracic duct damage. The effusion is most commonly unilateral, with the right and left side being affected in 50% and 33.3% of the patients, respectively.

Effects of Starting Stance on Base Running Sprint Speed in Softball Players.

Speed is a crucial aspect in softball, and can be the difference between winning and losing. Base stealing is a method used to produce runs. There has been debate over which starting position is the most advantageous to maximize acceleration and speed to reach the next base the fastest.

Repeated Plyometric Exercise Attenuates Blood Glucose in Healthy Adults.

Plyometric exercise is popular in commercial exercise programs aiming to maximize energy expenditure for weight loss. However, the effect of plyometric exercise on blood glucose is unknown. The purpose of this study was to investigate the effect of relatively high intensity plyometric exercise on blood glucose.

Sled Towing Acutely Decreases Acceleration Sprint Time.

Wong, MA, Dobbs, IJ, Watkins, C, Barillas, SR, Lin, A, Archer, DC, Lockie, RG, Coburn, JW, and Brown, LE. Sled towing acutely decreases acceleration sprint time. J Strength Cond Res 31(11): 3046-3051, 2017-Sled towing is a common form of overload training in sports to develop muscular strength for sprinting.

Bench Press Upper-Body Muscle Activation Between Stable and Unstable Loads.

The bench press is one of the most commonly used upper-body exercises in training and is performed with many different variations, including unstable loads (ULs). Although there is much research on use of an unstable surface, there is little to none on the use of an UL. The purpose of this study was to investigate muscle activation during the bench press while using a stable load (SL) vs.

Uncultured adipose-derived regenerative cells (ADRCs) seeded in collagen scaffold improves dermal regeneration, enhancing early vascularization and structural organization following thermal burns.

Objective: Advances in tissue engineering have yielded a range of both natural and synthetic skin substitutes for burn wound healing application. Long-term viability of tissue-engineered skin substitutes requires the formation and maturation of neo-vessels to optimize survival and biointegration after implantation. A number of studies have demonstrated the capacity of Adipose Derived Regenerative Cells (ADRCs) to promote angiogenesis and modulate inflammation.

Human leucocytes response to viable, extended freeze-drying or heat-killed Mycobacterium bovis bacillus Calmette-Guérin.

We investigated the effects of viable, extended freeze-drying (EFD) or heat-killed (HK) Mycobacterium bovis bacillus Calmette-Guérin (BCG) in respiratory burst activity, gene expression of CYBB and NCF1 encoding components of the human phagocyte nicotinamide adenine dinucleotide (NADPH) oxidase, TLR2 expression, and in IL-10 and TNF-α cytokine production by human peripheral blood mononuclear cells (PBMCs). Viable BCG significantly inhibited TLR2 and CYBB gene expression, as well as superoxide release by human PBMC. All BCG stimuli augmented IL-10 release, but only HK BCG or viable BCG increased TNF-α release by PBMCs.

Role of a novel tetrodotoxin-resistant sodium channel in the nitrergic relaxation of corpus cavernosum from the South American rattlesnake Crotalus durissus terrificus.

Introduction: Coitus in snakes may last up to 28 hours; however, the mechanisms involved are unknown.

Aim: To evaluate the relevance of the nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-phosphodiesterase type 5 (PDE5) system in snake corpus cavernosum reactivity.

Methods: Hemipenes were removed from anesthetized South American rattlesnakes (Crotalus durissus terrificus) and studied by light and scanning electronic microscopy.

Chapter 7. Mouse models of ischemic angiogenesis and ischemia-reperfusion injury.

Ischemia and ischemia-reperfusion (I/R) events are distinct but interrelated processes etiologic to the most prevalent human diseases. A delicate balance exists whereby ischemic injury can result in beneficial angiogenesis or in detrimental reperfusion injury overwhelming the organism. Here, we describe in vivo models of ischemia and ischemia-reperfusion injury with emphasis on murine hindlimb ischemia models.

A role for VEGF as a negative regulator of pericyte function and vessel maturation.

Angiogenesis does not only depend on endothelial cell invasion and proliferation: it also requires pericyte coverage of vascular sprouts for vessel stabilization. These processes are coordinated by vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) through their cognate receptors on endothelial cells and vascular smooth muscle cells (VSMCs), respectively. PDGF induces neovascularization by priming VSMCs/pericytes to release pro-angiogenic mediators.

Carotid endarterectomy as the criterion standard in high-risk elderly patients.

Background: Carotid angioplasty and stenting (CAS) is now a viable alternative to carotid endarterectomy (CEA) in patients considered to be high-risk candidates for surgery, despite recent reports of increased adverse periprocedural outcomes in elderly patients. We sought to evaluate our single-institution experience and the 30-day perioperative outcomes of CEA in patients 75 years or older, who are traditionally considered high-risk surgical candidates and are recommended for CAS.

Design: Retrospective medical record review.

Semaphorin 3A suppresses VEGF-mediated angiogenesis yet acts as a vascular permeability factor.

Semaphorin 3A (Sema3A), a known inhibitor of axonal sprouting, also alters vascular patterning. Here we show that Sema3A selectively interferes with VEGF- but not bFGF-induced angiogenesis in vivo. Consistent with this, Sema3A disrupted VEGF- but not bFGF-mediated endothelial cell signaling to FAK and Src, key mediators of integrin and growth factor signaling; however, signaling to ERK by either growth factor was unperturbed.

A novel fluorescence-based cellular permeability assay.

Vascular permeability is a pathologic process in many disease states ranging from metastatic progression of malignancies to ischemia-reperfusion injury. In order to more precisely study tissue, and more specifically cell layer permeability, our goal was to create a fluorescence-based assay which could quantify permeability without radioactivity or electrical impedance measurements. Human aortic endothelial cells were grown in monolayer culture on Costar-Transwell clear polyester membrane 6-well cell culture inserts.
