Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcoma to treat. Currently, general local control is obtained with surgical treatment with wide negative margins. We describe the case of a 50-year-old man who underwent a chest wall resection involving a wide portion of the pectoralis major and minor muscle, the serratus and part of the second, third and fourth ribs of the left side...

Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma with a propensity for lung metastases and indolent progression. ASPS is not responsive to chemotherapy, but there are case reports and small series describing benefit from drugs targeting the VEGF pathway. These drugs include sunitinib, cediranib and bevacizumab. There is no established second-line treatment for persons with ASPS progressing through first-line targeted therapy. We report two individuals with metastatic ASPS who obtained disease stabilization from sunitinib lasting over a year...

Over the past several decades, the automotive industry has expended significant effort to develop lightweight parts from new easy-to-process polymeric nanocomposites. These materials have been particularly attractive because they can increase fuel efficiency and reduce greenhouse gas emissions. However, attempts to reinforce soft matrices by nanoscale reinforcing agents at commercially deployable scales have been only sporadically successful to date. This situation is due primarily to the lack of fundamental understanding of how multiscale interfacial interactions and the resultant structures affect the properties of polymer nanocomposites...

The CIC-DUX4 sarcoma is a subset of the undifferentiated small round cell sarcoma family, presently recognized as a new clinicopathological entity. It is a rare and highly aggressive tumor usually arising in the soft parts of the limbs and the trunk. Only a very few cases of primitive visceral CIC-DUX4 have been hitherto described. We report the case of a 29 year-old male patient with a primary CIC-DUX4 sarcoma of the kidney with lung metastasis. The outcome of the disease was rapidly unfavorable. Despite radical nephrectomy, the patient experienced an early local retroperitoneal recurrence associated with lung and liver metastases...

Mehrdad Mirbabayi, Massimo Porrati
A recent, intriguing Letter by Hawking, Perry, and Strominger suggests that soft photons and gravitons can be regarded as black hole hair and may be relevant to the black hole information paradox. In this Letter we make use of factorization theorems for infrared divergences of the S matrix to argue that by appropriately dressing in and out hard states, the soft-quanta-dependent part of the S matrix becomes essentially trivial. The information paradox can be fully formulated in terms of dressed hard states, which do not depend on soft quanta...

We have shown previously that PMMA-acrylate photopolymers are biocomopatible and can exhibit improved cell adhesion compared to PMMA, due to an increase in negative surface charge caused by UV radiation PLGA has been used widely in soft tissue regeneration due to its high biocompatibility and cell adhesion. This polymer is also biodegradable and can be utilised in the field of vascular regeneration. In this study, PLGA is blended with a triacrylate monomer (TPETA) to create a degradable photopolymer blend. Surface relief structures are formed on this PLGA-TPETA by photoembossing...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common nosocomial infection, which results in longer hospitalization, increased treatment costs, and higher mortality rates. One major cause of VAP is colonization and microaspiration of oropharyngeal secretions following the formation of dental plaque, which is due to poor oral hygiene and failure to mechanically remove these microorganisms from the teeth. This study was conducted to determine the effect of brushing teeth with distilled water on the incidence of VAP in patients admitted to intensive care unit (ICU)...

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric population. In 35% of cases, RMS develops in the head and neck (H&N) region, and only combined therapy is recognized as a curative treatment. However, recent advances in skull base and reconstructive surgery, along with microsurgery and endoscopic surgery, have strengthened the role of surgery as an important part of RMS treatment. In the present study, 36 pediatric RMS cases (24 males and 12 females) were analyzed after surgical treatment...

Hereditary paroxysmal dyskinesias (PxD) are a heterogeneous group of movement disorders classified by frequency, duration, and triggers of the episodes. A young-adult onset canine PxD has segregated as an autosomal recessive trait in Soft-Coated Wheaten Terriers. The medical records and videos of episodes from 25 affected dogs were reviewed. The episodes of hyperkinesia and dystonia lasted from several minutes to several hours and could occur as often as >10/day. They were not associated with strenuous exercise or fasting but were sometimes triggered by excitement...

Pancreatic ductal adenocarcinoma (PDAC), a poor prognostic cancer, commonly develops following activating mutations in the KRAS oncogene. Activation of WNT signaling is also commonly observed in PDAC. To ascertain the impact of postnatal activation of WNT-stimulated signaling pathways in PDAC development, we combined the Elastase-tva-based RCAS-TVA pancreatic cancer model with the established LSL-Kras(G12D), Ptf1a-cre model. Delivery of RCAS viruses encoding β-catenin(S37A) and WNT1 stimulated the progression of premalignant pancreatic intraepithelial neoplasias (PanIN) and PDAC development...

The patients with secondary bilateral cleft lip and nasal deformity always suffer from a serious part of the horizontal and vertical soft tissue deficiencies in the upper lip and nose, especially the columella. Normally, the Abbe flap is used to increase the soft tissue volume of upper lip. However, how to reconstruct the sever columella deficient, how to make full use of the Abbe flap and the remaining soft tissue of the upper lip, are always the problems that need to be solved by plastic surgeons. Twenty-nine patients with secondary bilateral cleft lip and severe columella deficiency were simultaneously reconstructed with several local flaps like dominos that was called "Domino sliding flaps...
