Photodynamic therapy (PDT) is a promising tumor treatment modality that can convert oxygen into cytotoxic singlet oxygen (SO) via photosensitizer to ablate tumor growth. However, the uncontrolled cancer cell proliferation during tumor development and the oxygen consumption during PDT always result in an insufficient oxygen level in tumors, which can adversely affect the PDT efficiency in turn. We designed an oxygen-generating PDT nanocomplex by encapsulating a manganese dioxide nanoparticle (MnO2 NP) in an indocyanine green (ICG) modified hyaluronic acid nanoparticle (HANP) to overcome this limitation...

BACKGROUND: Allergic contact dermatitis after exposure to p-phenylenediamine (PPD)-containing hair dye products is a common and important clinical problem. Because there is a high rate of cross-elicitation of allergic contact dermatitis to other important hair dye products (such as p-toluene diamine and other aminophenol hair dyes) in PPD-allergic patients, safer alternative dyes with excellent hair coloring options are needed. OBJECTIVE: This study aimed to study tolerance to Me-PPD in a PPD-allergic cohort...

INTRODUCTION: The Rubinstein-Taybi syndrome and pancreas divisum are uncommon diseases in children. The Rubinstein-Taybi syndrome diagnosis is only clinical, and mental retardation and dysmorphic features mainly characterize it. The PD relates to idiopathic pancreatitis in 7.5% of patients suffering from this disorder. It has not been found any cases reported where these diseases are associated and the management of patients with pancreatitis associated with PD is still a challenge. CLINICAL CASE: A patient diagnosed with Rubinstein-Taybi syndrome has recurrent abdominal pain of six months and elevated pancreatic enzymes, he underwent a magnetic resonance imaging where pancreas divisum is suspected...

The Glasgow Coma Scale (GCS) has limited utility in intubated patients due to the inability to assign verbal sub-scores. The verbal sub-score can be derived from the eye and motor sub-scores using a mathematical model, but the advantage of this method and its use in outcome prognostication in traumatic brain injury (TBI) patients remains unknown. We compared the validated "Core+CT"-IMPACT-model performance in 251 intubated TBI patients prospectively enrolled in the longitudinal OPTIMISM-study between November 2009 and May 2015 when substituting the original motor GCS with the total estimated GCS (teGCS; with estimated verbal sub-score)...

BACKGROUND: Stroke is one of the leading causes of death and disability worldwide. As a consequence, several excellent rodent models have been developed to gain insight into the pathophysiology of stroke and testing the efficacy of neuroprotective interventions. However, one potential problem is that albeit roughly 80% of strokes occur in awake patients, all existing murine stroke models employ anesthesia. Moreover, epidemiological studies have shown that stroke injury is more severe in the minority of patients that suffer stroke while asleep...

Bio-functionalization means to endow biomaterials with bio-functions so as to make the materials or devices more suitable for biomedical applications. Traditionally, because of the excellent mechanical properties, the biomedical metals have been widely used in clinic. However, the utilized functions are basically supporting or fixation especially for the implantable devices. Nowadays, some new functions, including bioactivity, anti-tumor, anti-microbial, and so on, are introduced to biomedical metals. To realize those bio-functions on the metallic biomedical materials, surface modification is the most commonly used method...

Relaxin is a small heterodimeric peptide hormone of the insulin/relaxin superfamily produced mainly in female and male reproductive organs. It has potent antifibrotic, vasodilatory, and angiogenic effects and regulates the normal function of various physiological systems. Preclinical studies and recent clinical trials have shown the promise of recombinant relaxin as a therapeutic agent in the treatment of cardiovascular and fibrotic diseases. However, there are universal drawbacks of peptide-based pharmacology which apply to relaxin: a short half-life in vivo requires its continuous delivery, there are high costs of production, storage and treatment, as well as the possibility of immune response...

The (68)Ge/(68)Ga generator system is an excellent source for producing ready-to-use Ga-68 in clinical Positron Emission Tomography (PET) applications. The column adsorbent is the key component for the (68)Ge/(68)Ga generator system. Therefore, several studies have been conducted to identify column materials with a stable and superior elution yield in an acidic eluent (0.1 N HCl solution). In this study, four different zirconium phosphates were synthesized with a particle size of 200-800nm, pore-size of 55∼190Å and surface area of 0...

In recent years, magnesium alloys are attracting more and more attention as a kind of biodegradable metallic biomaterials, however, their uncontrollable biodegradation speed in vivo and the limited surface biocompatibility hinder their clinical applications. In the present study, with the aim of improving the corrosion resistance and biocompatibility, the magnesium alloy (AZ31B) surface was modified by alkali heating treatment followed by the self-assembly of 3-aminopropyltrimethoxysilane (APTMS). Subsequently, poly (ethylene glycol) (PEG) and fibronectin or fibronectin/heparin complex were sequentially immobilized on the modified surface...

With its proven biocompatibility and excellent mechanical properties, iron is an excellent source material for clinical cardiac and vascular applications. However, its relatively low degradation rate limits its use for the healing and remodeling of diseased blood vessels. To address these issues, a multi-purpose fabrication process to develop a bilayer alloy composed of electroformed iron (E-Fe) and iron-phosphorus (Fe-P) was employed. Bilayers of Fe/Fe-P were produced in an electrolytic bath. The effects of electrolyte chemical composition and deposition current density (idep) on layer structure and chemical composition were assessed by scanning electron microscopy, electron probe microanalysis, X-ray diffraction and X-ray photoelectron spectroscopy...
