INTRODUCTION: Glans penis augmentation (GPA) using hyaluronic acid (HA) gel has been developed for treating premature ejaculation (PE) with penile hypersensitivity. The injected HA filler creates a barrier that reduces the tactile stimuli to the hypersensitive dorsal nerve. Although the HA filler is biodegradable and is believed to not cause permanent loss of sexual function, the current International Society for Sexual Medicine guideline for PE does not recommend this procedure owing to concerns regarding sexual dysfunction...

BACKGROUND: Cardiovascular magnetic resonance (CMR) fluoroscopy allows for simultaneous measurement of cardiac function, flow and chamber pressure during diagnostic heart catheterization. To date, commercial metallic guidewires were considered contraindicated during CMR fluoroscopy due to concerns over radiofrequency (RF)-induced heating. The inability to use metallic guidewires hampers catheter navigation in patients with challenging anatomy. Here we use low specific absorption rate (SAR) imaging from gradient echo spiral acquisitions and a commercial nitinol guidewire for CMR fluoroscopy right heart catheterization in patients...

INTRODUCTION: In recent years microinvasive glaucoma surgery has risen in popularity. Among microinvasive glaucoma surgery options is the XEN gel stent (Allergan Plc, Dublin, Ireland), a 45 μm wide ab-interno microstent. It has proven effective in lowering intraocular pressure (IOP) with low complication rates. However, XEN gel stents can become obstructed and cause postoperative rise in IOP. The causes and predicting factors for such obstructions still requires further research. CASE REPORT: We describe the case of a 69-year-old male patient, with traumatic glaucoma and chronic intraocular inflammation showed by laser flare photometry, following childhood trauma and anterior segment surgery...

 Only 4 classes of antifungal agents comprising 9 compounds are effective against deep mycosis in Japan, and it has been difficult to develop new antifungal specific agents. Micafungin, which has been used as an antifungal agent since 2002, inhibits β-1,3-glucan synthesis in fungal cell walls, thereby killing yeast and filamentous fungi with no septum. In this study, we constructed a pYES2-BGL2 vector to overexpress β-1,3-glucanase (BGL2) in yeast (Saccharomyces cerevisiae INVSc1) and evaluated the synergy between BGL2 overexpression and conventional antifungal agents...

Back and neck pain are commonly associated with intervertebral disc (IVD) degeneration. Structural augmentation of diseased nucleus pulposus (NP) tissue with biomaterials could restore degeneration-related IVD height loss and degraded biomechanical behaviors; however, effective NP replacement biomaterials are not commercially available. This study developed a novel, crosslinked, dual-polymer network (DPN) hydrogel comprised of methacrylated carboxymethylcellulose (CMC) and methylcellulose (MC), and used in vitro, in situ and in vivo testing to assess its efficacy as an injectable, in situ gelling, biocompatible material that matches native NP properties and restores IVD biomechanical behaviors...

Early stages of inflammation are characterized by extensive oxidative insult by recruited and activated neutrophils. Secretion of peroxidases, including the main enzyme, myeloperoxidase, leads to the generation of reactive oxygen species. We show that this oxidative insult leads to polyunsaturated fatty acid (eg, docosahexaenoate), oxidation, and accumulation of its product 2-(ω-carboxyethyl)pyrrole (CEP), which, in turn, is capable of protein modifications. In vivo CEP is generated predominantly at the inflammatory sites in macrophage-rich areas...

Restoring adequate blood supply is essential to the success of bone repair and augmentation procedures in craniofacial surgery. Nevertheless, the manner by which the incorporation of collagen gels (which can potentially induce angiogenesis), particulated deproteinized bovine bone grafts, or a combination of both can accelerate or delay bone regeneration in a clinical setting remains controversial. The objective of this study was to evaluate radiographically and histologically the capacity and functionality of particulated bone grafts and collagen gels on bone ossification and soft tissue formation in a rabbit calvarial defect...

BACKGROUND AND OBJECTIVE: In a phase II clinical trial, carboplatin (CBDCA) displayed the response rate of 19% equivalent to dacarbazine in the treatment of malignant melanoma. However, besides desirable therapeutic profile, intravenous (i.v) administration of CBDCA delivers a subtherapeutic concentration at the target site. This entails administration of CBDCA through an alternate route by using nanovectors to achieve therapeutic efficacy in the treatment of melanoma. METHODS AND RESULTS: Carboplatin loaded poly(ε-caprolactone) nanoparticles (CBDCA-PCL-NPs) were formulated and amalgamated with chitosan-β-glycerophosphate gel (CBDCA-PCL-NPs-Gel) for intratumoral (i...

The purpose of this study is to offer a novel kind of polyurethane with improved surface blood compatibility for long-term implant biomaterials. In this work, the aliphatic poly(ester-urethane) (PEU) with uniform-size hard segments was prepared and the PEU surface was grafted with hydrophilic poly(ethylene glycol) (PEG). The PEU was obtained by chain-extension of poly(ɛ-caprolactone) (PCL) with isocyanate-terminated urethane triblock. Free amino groups were introduced onto the surface of PEU film via aminolysis with hexamethylenediamine, and then the NH2 -grafted PEU surfaces (PEU-NH2 ) were reacted with isocyanate-terminated monomethoxyl PEG (MPEG-NCO) to obtain the PEG-grafted PEU surfaces (PEU-PEG)...
