Critical elements of pediatric neuroblastoma surgery.

Neuroblastoma (NB) is the most common solid extracranial malignancy of childhood with an incidence of 1 per 100,000 in the United States compromising approximately 10 % of childhood cancer. Unfortunately, patients with high-risk NG continue to have long-term survival less than 50 %. Both Children's Oncology Group and the International Society of Paediatric Oncology have demonstrated the important role of surgery in the treatment of high-risk NB.

Outcomes and cost of medical and surgical treatments of pilonidal disease: A single institution's 10-year review.

Background: Pilonidal disease is a chronic inflammatory skin disorder typically located in the gluteal cleft. Treatment varies from antibiotic therapy to extensive surgical resection and reconstruction; however, complications and recurrence are common. To understand risk factors, outcomes, and costs associated with various treatments, we performed a retrospective chart review of all patients treated for pilonidal disease at a single health care system from 2008 to 2018.

Interhospital variability in localization techniques for small pulmonary nodules in children: A pediatric surgical oncology research collaborative study.

Background: Pulmonary nodules that are deep within lung parenchyma and/or small in size can be challenging to localize for biopsy. This study describes current trends in performance of image-guided localization techniques for pulmonary nodules in pediatric patients.

Methods: A retrospective review was performed on patients < 21 years of age undergoing localization of pulmonary nodules at 15 institutions.

A cytosolic disulfide bridge-supported dimerization is crucial for stability and cellular distribution of Coxsackievirus B3 protein 3A.

RNA viruses in the Picornaviridae family express a large 250 kDa viral polyprotein that is processed by virus-encoded proteinases into mature functional proteins with specific functions for virus replication. One of these proteins is the highly conserved enteroviral transmembrane protein 3A that assists in reorganizing cellular membranes associated with the Golgi apparatus. Here, we studied the molecular properties of the Coxsackievirus B3 (CVB3) protein 3A with regard to its dimerization and its functional stability.

A Helminth-Derived Chitinase Structurally Similar to Mammalian Chitinase Displays Immunomodulatory Properties in Inflammatory Lung Disease.

Immunomodulation of airway hyperreactivity by excretory-secretory (ES) products of the first larval stage (L1) of the gastrointestinal nematode is reported by us and others. Here, we aimed to identify the proteins accounting for the modulatory effects of the L1 ES proteins and studied six selected L1 proteins for their immunomodulatory efficacy in a murine OVA-induced allergic airway disease model. In particular, an enzymatically active chitinase mediated amelioration of clinical signs of airway hyperreactivity, primarily associated with suppression of eosinophil recruitment into the lung, the associated chemokines, and increased numbers of RELM interstitial lung macrophages.
