BACKGROUND AND IMPORTANCE: Dissection of cerebellopontine angle (CPA) tumors that abut or adhere to the brainstem or cranial nerves can be a challenging surgical endeavor. We describe the use of semitranslucent latex rubber pledgets in the tumor-brain interface as a method to improve visualization and protection of vital tissue during microsurgical dissection of CPA masses. The rubber pledgets are fashioned by cutting circular discs out of the cuff portion of talc-free, partially opaque latex gloves...

BACKGROUND: A patency capsule (PC) can help predict capsule endoscope (CE) retention; however, PC tolerability is unknown in children. We retrospectively evaluated PC tolerability in school-aged children. METHODS: Sixty-one patients (median age, 12.9 years; range 7.4-17.3 years) who underwent PC examination were analyzed for occurrence and determinants of ingestion difficulty and relationships between ingestion of the 2 capsules. We defined ingestion difficulty as taking 30 min or more, or failure, to ingest the PC...

DNA vaccination is one method to protect farmed fish from viral and bacterial diseases. Chimeric antigens encoded by DNA vaccines have been shown to increase the resistance to viral diseases. Here, we sequenced the gene encoding lysosome-associated membrane protein-1 from Japanese flounder, Paralichthys olivaceus, (JfLAMP-1) and assessed its use in a chimeric DNA vaccine fused with the major capsule protein (MCP) from red seabream iridovirus (RSIV). JfLAMP-1 cDNA has a length of 1248 bp encoding 415 aa, which contains transmembrane and cytoplasmic domains...

A time-adjustable pulsatile release system (TAPS) containing ketoprofen (KF) as an active pharmaceutical agent was developed having been designed for bedtime dosing and releasing drug in the early morning to control the symptoms of rheumatoid arthritis (RA). The formulation involved a tablet core (KF) and a control-release layer, and the coating membrane was composed of EC and Eudragit L100. A single-factor study, a central composite design and a response surface method were selected to optimize the formula and the optimum prescription was as follows: tablet core (KF 50mg, MCC 70mg, lactose 40mg, L-HPC 38mg), and film (EC 7...

Although ankle arthrodesis is the reference standard for end-stage ankle arthritis, loss of mobility and adjacent joint arthritis are consequences that alternatives to arthrodesis attempt to avoid. The purpose of the present study was to report the clinical results of interpositional arthroplasty using acellular dermal matrix in 4 patients (age 32 to 42 years) for the treatment of advanced ankle osteoarthritis. The primary findings included relief of pain, with improvement in tibiotalar joint range of motion from a mean of 16...

Irreducible ankle fractures are a relatively rare phenomenon. We present a case of a pronation abduction-type ankle fracture that was irreducible in the emergency room despite sedation. The patient was taken to the operating room, where the posterior tibialis tendon and retinaculum, deltoid ligament, and anteromedial capsule were found to be trapped within the joint. After removal of the tissue, alignment was restored. The patient did well clinically and was advanced to full weightbearing at 6 weeks. This is, to the best of our knowledge, the first report of entrapment of all 4 anatomic structures, preventing closed reduction...

Glycomics is a rapidly growing field that focuses on the structure and function of carbohydrates (glycans) in biological systems. Glycan interactions play a major role in infectious disease, at all stages of colonisation and disease progression. Neisseria meningitidis, the cause of meningococcal sepsis and meningitis, and Neisseria gonorrhoeae, which causes the sexually transmitted infection gonorrhoea, are responsible for significant morbidity and mortality worldwide. N. meningitidis displays a range of surface glycosylations including capsule polysaccharide, lipooligosaccharide and O-linked glycoproteins...

Transplantation of pancreatic islets encapsulated within immuno-protective microcapsules is a strategy that has the potential to overcome graft rejection without the need for toxic immunosuppressive medication. However, despite promising preclinical studies, clinical trials using encapsulated islets have lacked long-term efficacy, and although generally considered clinically safe, have not been encouraging overall. One of the major factors limiting the long-term function of encapsulated islets is the host's immunological reaction to the transplanted graft which is often manifested as pericapsular fibrotic overgrowth (PFO)...

Massive irreparable rotator cuff tears are difficult to treat. Although several treatment options exist, none provides superior long-term results. There is no consensus on optimal surgical technique. Superior capsular reconstruction is an operative treatment option aimed at restoring native biomechanics of the glenohumeral joint by providing a restraint to superior subluxation. Partial rotator cuff repair for massive tears has also been shown to improve shoulder kinematics and can be performed in conjunction with superior capsule reconstruction...

OBJECTIVES: Mesoporous silicas (SLC) have demonstrated considerable potential to improve bioavailability of poorly soluble drugs by facilitating rapid dissolution and generating supersaturation. The addition of certain polymers can further enhance the dissolution of these formulations by preventing drug precipitation. This study uses fenofibrate as a model drug to investigate the performance of an SLC-based formulation, delivered with hydroxypropyl methylcellulose acetate succinate (HPMCAS) as a precipitation inhibitor, in pigs...

Chondroprotectors (CP) are biological agents that contribute to the regeneration of the cartilage surfaces and articular capsule, participating in the metabolic processes of the articular cartilage. Progressive loss of hyaline cartilage and lower levels of chondroitin sulfate were observed in osteoarthritis (OA) at different sites, including dorsopathy. OA therapy is aimed at slowing disease progression, relieving pain symptoms, and reducing functional disorders. For this purpose, oral or injectable CPs (Chondroguard, Sustaguard) are prescribed...

By merging well-established concepts of supramolecular chemistry, protecting group strategy, and photochemistry, we have solubilized in water hydrophobic organic molecules consisting of a photoactive protecting group and masked carboxylic acids, released the desired acid, and confined a reactive carbocation intermediate within a capsule. Confinement of the photogenerated carbocation brought out the latent radical-like behavior. This observation is consistent with the recent theoretical prediction of the 7-(diethylamino)coumarinyl-4-methyl carbocation having a triplet diradical ground-state electronic contribution...

Recently, it has been shown that constructs of poly(vinyl alcohol) (PVA) hydrogel fibers reproduce closely the tensile behavior of ligaments. However, the biological response to these systems has not been explored yet. Here, we report the first in vivo evaluation of these implants and focus on the integration in bone, using a rabbit model of bone tunnel healing. Implants consisted in bundles of PVA hydrogel fibers embedded in a PVA hydrogel matrix. Half of the samples were coated with a composite coating of hydroxyapatite (HA) particles embedded in PVA hydrogel...

INTRODUCTION: Heterotopic ossification (HO) after hip surgery is the formation of bone in non-skeletal tissue, usually between the muscle and the joint capsule. HO after hip surgery may be associated with clinical sequelae such as pain, impingement and decreased range of motion, compromising surgical outcomes. CASE REPORT: A 20-year-old basketball player presented with a 2-year duration of the left groin pain after a basketball-related injury. Due to continued disability and failure of conservative management the patient underwent hip arthroscopy...
