To test the hypothesis that thrombus-specific tissue plasminogen activator (tPA)-loaded nanocarriers enhance thrombolytic efficacy and attenuate hemorrhagic complications. A series of pegylated and non-pegylated tPA-loaded liposomes were prepared and their surfaces were decorated with the peptide sequence (CQQHHLGGAKQAGDV) of fibrinogen gamma-chain that… (More)
Nanoerythrosomes (NERs), an engineered derivative of erythrocytes, have long been used as drug delivery carriers. These cell based carriers are biocompatible and biodegradable, and they exhibit efficient drug loading, targeting specificity and prolonged biological half-life. In this study, we have evaluated the feasibility of NERs as inhalable carriers for… (More)
This study sought to develop a liposomal delivery system of fasudil--an investigational drug for the treatment of pulmonary arterial hypertension (PAH)--that will preferentially accumulate in the PAH lungs. Liposomal fasudil was prepared by film-hydration method, and the drug was encapsulated by active loading. The liposome surface was coated with a… (More)
Ahsan F. Computational and bioengineered lungs as alternatives to whole animal, isolated organ, and cell-based lung models. of lung models for testing a drug substance or delivery system has been an intensive area of research. However, a model that mimics physiological and anatomical features of human lungs is yet to be established. Although in vitro lung… (More)
This study seeks to develop a liposomal formulation of diethylenetriamine NONOate (DN), a long acting nitric oxide (NO) donor, with a goal to replace inhaled NO (iNO) in the treatment of pulmonary arterial hypertension (PAH). Liposomal formulations were prepared by a lipid film hydration method and modified with a cell penetrating peptide, CAR. The… (More)
Cysteinyl leukotrienes (CysLTs) propagate inflammatory reactions that result from allergen exposure in asthma. Montelukast, a CysLT type-1 receptor antagonist, disrupts mediator–receptor interactions and minimizes inflammatory response. In this study, we have evaluated anti-asthmatic efficacy of inhalable montelukast-loaded large porous particulate… (More)
Regulation of BBB Na,K,2Cl-Cotransporter through phosphorylation during in vitro stroke conditions.
uptake kinetics of nicotine and cotinine after chronic nicotine exposure. lipophilic polycyclic cage amine, is neuroprotective in focal ischemia. Chronic nicotine exposure alters blood brain barrier permeability and diminishes brain uptake of methyllycaconitine. Tobacco smoke chemicals attenuate brain-to-blood potassium transport mediated by… (More)
