Emergence of drug resistance in tumors causes therapeutic failure or tumor relapse. Combination of chemotherapy and photodynamic therapy holds significant promise to treat drug-resistant tumors. However, stubborn hydrophobicity of photosensitizer (PS), low encapsulation efficiency and leaking problem of PS in organic carrier, and disparate physicochemical properties of PS and chemotherapeutics make the combination unachievable. Thus how to efficiently co-deliver the two functional agents to enable photo-chemotherapy seems to be one of the key challenges...

BACKGROUND: Visceral leishmaniasis is a neglected parasitic disease with no vaccine available and its pharmacological treatment is reduced to a limited number of unsafe drugs. The scarce readiness of new antileishmanial drugs is even more alarming when relapses appear or the occurrence of hard-to-treat resistant strains is detected. In addition, there is a gap between the initial and late stages of drug development, which greatly delays the selection of leads for subsequent studies. METHODOLOGY/PRINCIPAL FINDINGS: In order to address these issues, we have generated a red-shifted luminescent Leishmania infantum strain that enables long-term monitoring of parasite burden in individual animals with an in vivo limit of detection of 106 intracellular amastigotes 48 h postinfection...

Compartment syndrome is an orthopedic emergency in which the neurovasculature of the extremity is compromised. Typically, it presents unilaterally and is the consequence of major trauma to the extremity in the form of fracture. However, more uncommon etiologies of compartment syndrome have been reported, which includes reperfusion injury, burns, and congenital or acquired bleeding disorders. We present an extremely rare case of bilateral posterior thigh compartment syndrome thought to be due to intravenous drug abuse (IVDA) causing prolonged ischemia with subsequent reperfusion...

Baicalin is a natural compound isolated from Chinese herb, which has been reported as an anti-inflammatory drug. Here, we demonstrated that Baicalin treatment could reduce urine protein, inhibit anti-ds-DNA antibody titers, and ameliorate lupus nephritis in MRL/lpr lupus-prone mice. Baicalin inhibited Tfh cell differentiation and IL-21 production, but promoted Foxp3+ regulatory T cell differentiation including part of follicular regulatory T (Tfr) cells. Intravenous injection of Baicalin-induced Foxp3+ regulatory T cells could relieve nephritis, inhibit Tfh cell differentiation and IL-21 production...

The therapeutic effect of a drug is governed by its pharmacokinetics which determine the downstream pharmacodynamic response within the cellular network. A complete understanding of the drug-effect relationship therefore requires multi-scale models which integrate the properties of the different physiological scales. Computational modelling of these individual scales has been successfully established in the past. However, coupling of the scales remains challenging, although it will provide a unique possibility of mechanistic and holistic analyses of therapeutic outcomes for varied treatment scenarios...

BACKGROUND: Randomized placebo-controlled trials in the development of disease-modifying treatments for Alzheimer's disease are typically of short duration (12-18 months), and health economic modeling requires extrapolation of treatment effects beyond the trial period. OBJECTIVES: To investigate whether observational data can be used to extrapolate data from open-label trials, we compared outcomes (cognition, function, behavior) over 36 months for patients with mild Alzheimer's disease dementia in the GERAS observational study (proxy for placebo control) with those of the mild Alzheimer's disease population on active treatment (solanezumab) in two 18-month randomized placebo-controlled trials (EXPEDITION and EXPEDITION2) and the additional 18-month open-label extension study (EXPEDITION-EXT)...

Over the past five decades, the incidence of intravenous drug use- (IVDU-) associated infective endocarditis (IE) has been on the rise in North America. Classically, IVDU has been thought to affect right-sided valves. However, in recent times a more variable presentation of IVDU-associated IE has been reported. Here, we report a case of a patient with a known history of IVDU who presented with clinical symptoms concerning for right- as well as left-sided endocarditis. In addition, we also discuss what should be considered adequate evaluation for patients with suspected endocarditis, and more specifically, what should be the role of transesophageal echocardiography in patients with IE noted on transthoracic echocardiography...

BACKGROUND: CT-P10 is the first biosimilar of the anti-CD20 monoclonal antibody, rituximab. CT-P10 is currently available in over 51 countries worldwide, where it is approved in the same indications as its reference product rituximab. In-use stability studies are conducted for biologics to determine how conditions (e.g., temperature, light, humidity, length of time stored) affect drug quality following dilution and storage in infusion bags. OBJECTIVE: We evaluated the in-use stability of CT-P10 for intravenous infusion stored diluted in infusion bags over longer periods than currently recommended by manufacturer guidelines...

1. The prediction of human pharmacokinetic (PK) parameters is an important theme to select drug candidates from preclinical studies. It is essential to improve the prediction accuracy of compound half-life (t1/2 ) in humans. In this study, the predictability of t1/2 in humans using PXB mice®, chimeric mice with humanised liver, was assessed using 14 compounds showing long t1/2 in humans. 2. After intravenous administration of the compounds to PXB mice, the plasma concentration-time profiles were fitted using one- or two-compartment models and the human clearance (CLt ) and distribution volume (Vdss ) were predicted from single-species scaling...

Inherited retinopathies typically lead to photoreceptor loss and severe visual impairments in the subjects. Intranasal administration is an efficient approach to deliver therapeutic agents to the targeted tissue. The present study is designed to deliver the erythropoietin (EPO) into the N-methyl-N-nitrosourea (MNU) induced mice, a pharmacological retinopathy model via intranasal or intravenous route. The mice were then subjected to bioavailability assay and therapeutic effects evaluation. Our results showed that the intranasal delivery of EPO is effective to alleviate the morphological disruptions in the MNU induced mice...

ENHANZE® drug delivery technology is based on the proprietary recombinant human hyaluronidase PH20 enzyme (rHuPH20; Halozyme Therapeutics, Inc.) that facilitates the subcutaneous (SC) delivery of co-administered therapeutics. rHuPH20 works by degrading the glycosaminoglycan hyaluronan (HA), which plays a role in resistance to bulk fluid flow in the SC space, limiting large volume SC drug delivery, dispersion, and absorption. Co-administration of rHuPH20 with partner therapies can overcome administration time and volume barriers associated with existing SC therapeutic formulations, and has been shown to reduce the burden on patients and healthcare providers compared with intravenous formulations...
