At the intersection of the newly emerging fields of optoacoustic imaging and theranostic nanomedicine, promising clinical progress can be made in dismal prognosis of ovarian cancer. An acidic pH targeted wormhole mesoporous silica nanoparticle (V7-RUBY) was developed to serve as a novel tumor specific theranostic nanoparticle detectable using multispectral optoacoustic tomographic (MSOT) imaging. We report the synthesis of a small, < 40 nm, biocompatible asymmetric wormhole pore mesoporous silica core particle that has both large loading capacity and favorable release kinetics combined with tumor-specific targeting and gatekeeping...

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by the presence of a complex of signals resulting from the loss of REM sleep atony and manifested by vigorous and sometimes violent motor jerks and nocturnal vocalizations associated with dream enactment. RBD might be a clinical predictor of severity for Parkinson's disease (PD) and one of its most important non-motor manifestations, preceding the emergence of synucleinopathy by several years or even decades. The detection of RBD may represent a therapeutic window for research regarding the development of new neuroprotective therapies with the potential to modify the natural course of synucleinopathies, such as PD...

Among the various causative factors involved in the pathogenesis of Alzheimer's disease (AD), oxidative stress has emerged as an important factor. Phloroglucinol is a polyphenol component of phlorotannin, which is found at sufficient levels in Ecklonia cava (E. cava). Phloroglucinol has been reported to exert antioxidant activities in various tissues. Previously, we reported that the stereotaxic injection of phloroglucinol regulated synaptic plasticity in an AD mouse model. In this study, we aimed to investigate the effects of oral administration of phloroglucinol in AD...

Lateral habenula (LHb) hyperactivity plays a pivotal role in the emergence of negative emotional states, including those occurring during withdrawal from addictive drugs. We have previously implicated cocaine-driven adaptations at synapses from the entopeduncular nucleus (EPN) to the LHb in this process. Specifically, ionotropic GABAA receptor (R)-mediated neurotransmission at EPN-to-LHb synapses is reduced during cocaine withdrawal, due to impaired vesicle filling. Recent studies have shown that metabotropic GABAB R signaling also controls LHb activity, although its role at EPN-to-LHb synapses during drug withdrawal is unknown...

INTRODUCTION: Entero-neovesical fistula is a rare complication after radical cystectomy and orthotopic ileal bladder substitution. Typical presenting symptoms are faecaluria, pneumaturia, recurrent urinary tract infections and abdominal pain. Risk factors include history of pelvic radiation, chemotherapy and abdominal surgery, as well as diverticular colonic disease, inflammatory bowel disease and traumatic pelvic injury. The paucity of cases reported in the literature makes the management of this threatening complication very challenging...

BACKGROUND: Use of prehospital stroke scales may enhance stroke detection and improve treatment rates and delays. Current scales, however, may lack detection accuracy. As such, we examined if coordination and diplopia (Balance and Eyes) assessments increase the accuracy of the Face-Arms-Speech-Time (FAST) scale in a multi-site prospective study of emergency response activations for presumed stroke. METHODS: This was a prospective study of emergency response activations for presumed stroke in Santa Clara County, California...

BACKGROUND: Hemorrhage remains a leading cause of death in both civilian and military settings. Of preventable deaths from hemorrhage, a significant portion occurs from junctional wounds that are not amenable to traditional extremity tourniquets. Junctional tourniquets (JTQs) can potentially provide hemorrhage control by compressing the arteries at the junction of the trunk and extremities. The FDA has cleared 3 JTQ products: The Combat Ready Clamp (CRoC®), the Junctional Emergency Treatment Tool (JETT™), and the SAM® Junctional Tourniquet (SJT)...

Cutaneous lupus erythematosus (CLE) encompasses a spectrum of dermatologic manifestations which can occur with or without systemic lupus erythematosus (SLE). Treatment of CLE is challenging as the traditional treatments are off label and often fail and there is no drug specifically approved for CLE. The knowledge gained from the emerging trials on biologic therapy in SLE has provided insight into the utility of biologic therapy for CLE. Areas covered: An overview is provided on the biological agents studied for CLE discussing their immunological target, their efficacy in treating the various CLE manifestations and the outcome measures used...

Aspergillus fungal infections continue to be a significant cause of morbidity and mortality in birds that can, in part, be attributed to the lack of a diagnostic "gold standard" for Aspergillus infection, and which delays the diagnosis, treatment, and outcome of avian patients. At present, none of the available methods in veterinary care can detect aspergillosis early enough and with the accuracy, precision, and specificity required of an ideal diagnostic tool. Therefore, researching methods of Aspergillus detection is still an active area of inquiry, and novel techniques continue to emerge...

INTRODUCTION: Suicide is still a major event of human mortality worldwide. Yet human suicide prediction, prevention and therapeutic systems at this moment are generally ineffective in the clinic. No diagnostic system is reliable for significantly suicidal prevention and mortality reduction. As a result, human suicide etiopathologic investigation (especially at genetic/molecular levels in the clinical settings) is quite necessary. In order to boost human suicide researches, emerging human suicide diagnostic/treatment study will be transformed from clinical symptom observations into new generations of candidate drug targets and therapeutics...

Enhanced drug releases in a timely manner during urgent medical treatments would significantly enhance the prognosis of patients. Inspired by the facilitated molecular transports by the potentials, an enhanced drug release strategy driven by mechanical disturbances that widely exist in medical treatment processes is proposed. This strategy is enabled by a functional material comprised of multilayers of dendrimers as the drug reservoir, which are built on a piezoelectric-dielectric flexible film with reduced graphene oxide fillers...

The effects of ibrutinib on the natural history of autoimmune cytopenias (AIC) among chronic lymphocytic leukaemia (CLL) patients treated in routine clinical practice require further investigation. Using the Mayo Clinical CLL Database, 193 CLL patients treated with ibrutinib between November 2013 and January 2017 outside the context of a clinical trial were identified; complete review of their medical records was performed for details of past history of AIC and treatment-emergent AIC. We identified 29/193 (15%) patients with history of AIC prior to ibrutinib start...
