Carotid artery atherosclerosis is a risk factor to develop cerebrovascular disease. Atheroma plaque can become instable and provoke a cerebrovascular event or else remain stable as asymptomatic type. The exact mechanism involved in plaque destabilization is not known but includes among other events smooth muscle cell (SMC) differentiation. The goal of this study was to perform thorough analysis of gene expression differences in SMCs isolated from carotid symptomatic versus asymptomatic plaques. Comparative transcriptomics analysis of SMCs based on RNAseq technology identified 67 significant differentially expressed genes and 143 significant differentially expressed isoforms in symptomatic SMCs compared with asymptomatic...

Anterior cruciate ligament (ACL) injuries are one of the most well-known orthopaedic injuries and are treated with one of the most common orthopaedic procedures performed in the United States. This surgical procedure, ACL reconstruction, is successful at restoring the gross stability of the knee. However, the outcomes of ACL reconstruction can be limited by short and long term complications, including muscle weakness, graft rupture and premature osteoarthritis. Thus, new methods of treating this injury are being explored...

This study investigated the mode of action of wilforine, an alkaloid with insecticidal properties, extracted from Tripterygium wilfordii Hook f., on the microstructure and ultrastructure of the muscle cells of larvae and adults of the oriental armyworm Mythimna separata Walker. The bioassay results showed that wilforine had oral toxicity against both M. separata larvae (LC50=63μg/mL) and adults (LC50=36μg/mL). The typical toxicity sign was paralysis leading to death. Both light and electron microscope observations revealed that damage to the muscle cells increased with poisoning time in larvae and adults treated with the LC80 dose of wilforine...

A 30-year-old man presented with recurrent hematomas and tingling in his left leg, caused by a large femoral neck osteochondroma that induced multiple muscle ruptures and compressed the ischiadic nerve. There were no radiological signs of malignant transformation and symptoms disappeared without intervention. Hence, we chose a 'wait and see' approach instead of surgical removal of the osteochondroma.

Fatal injuries caused by attacks by large wild cats are extremely rare in forensic medical practice in Europe. There are very few cases described in the forensic medical literature concerning incidents in zoos similar to the tiger attack on a 58-year-old male zoo employee that we present here. While preparing a runway for tigers, the man was attacked by a male Sumatran tiger. Another zoo employee was an eyewitness to the accident; in his testimony he described the sequence of events in detail. The autopsy showed the injuries typical of a tiger attack: traces of claws and canine teeth indicating that the victim of the attack was knocked down from behind, along with deep and extensive fatal wounds to the neck...

Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures...

BACKGROUND: The vast majority of biceps tendon ruptures occurs at the proximal insertion and almost always involves the long head. There are several options for long head of biceps (LHB) tenodesis with advantage and disadvantages of each technique. We believe that the suprapectoral LHB tenodesis described in this article enables the restoration of the anatomic length-tension relation in a technically reproducible manner, when following the guidelines set forth in this article, and restores biceps contour and function adequately with a low risk of complications...

BACKGROUND: Atherosclerosis is a chronic process that progresses to unstable plaques. Plaque rupture leads to deleterious consequences such as acute coronary syndrome, thrombosis and stroke. AG1296 is a potent tyrosine kinase inhibitor which is able to block PDGF-PDGFR signaling pathway. This study aims to assess the effect of AG1296 on plaque stability and explore the potential mechanisms. METHODS: Atherosclerotic plaques were induced in carotid arteries in ApoE-/- mice by perivascular collar placement...

AIMS: Atherosclerotic plaques vulnerable to rupture are almost always inflamed, and carry a large lipid core covered by a thin fibrous cap. The other components may include neovascularisation, intraplaque haemorrhage and spotty calcification. In contrast, stable plaques are characterised by a predominance of smooth muscle cells and collagen, and lipid core is usually deep seated or absent. This study is a proof of principle experiment to evaluate the feasibility of multiphoton microscopy (MPM) to identify aforementioned plaque components...

RATIONALE: Death following orthopedic surgery has become rare, but does occur. Acute myocardial infarction (AMI) can be a cause of such death, but diagnosis of AMI is often challenging, even by autopsy. PATIENT CONCERNS: We have recently experienced 2 cases of sudden death after bone fracture surgery, in which AMI and pulmonary thromboembolism were clinically suspected as causes of death. Case 1 was a 60-year-old male with a history of diabetes mellitus who died 7 days after surgery for Lisfranc dislocation fracture...

Orbital fractures are injuries frequently related to traumas of the midface. These fractures can be associated with ocular lesions, ranging from small abrasions on the cornea to serious complications such as hyphema and ocular globe rupture. Diplopia and ophthalmoplegia are common findings in orbital fractures. They can be caused by mechanical factors as bone fragments or muscle imprisonment. The aim of this study was to report a case of a 40-year patient, male showing diplopia and ophthalmoplegia due to the orbital fracture...

Ischaemic papillary muscle rupture causing acute severe mitral regurgitation (MR) has a dramatic presentation and a very high mortality. Emergent surgical repair improves outcomes, which necessitates robust preoperative stabilisation. Here we discuss a patient with cardiogenic shock with an acute severe MR that was deemed very high risk for emergent valve replacement due to haemodynamic instability and respiratory failure. A percutaneous left ventricular assist device Impella 2.5 (Abiomed, Danvers, MA) drastically improved clinical status, and the patient underwent a successful surgical mitral valve replacement soon after placement of the temporary assist device...
