Human serum potently induces hyphal development of the polymorphic fungal pathogen Candida albicans, a phenotype that contributes critically to infections. The fungal adenylyl cyclase Cyr1p is a key component of the cAMP/PKA-signaling pathway that controls diverse infection-related traits, including hyphal morphogenesis. However, identity of the serum(More)
To determine the importance of single-chain Fv (scFv) affinity on binding, uptake, and cytotoxicity of tumor-targeting nanoparticles, the affinity of the epidermal growth factor receptor (EGFR) scFv antibody C10 was increased using molecular evolution and yeast display. A library containing scFv mutants was created by error-prone PCR, displayed on the(More)
The gut hormone glucagon-like peptide-1 (GLP-1) is proposed for treatment of Type II diabetes mellitus. However, the short half life of GLP-1 in vivo is a major limitation for its application due to the frequent invasive administrations. To provide a optimal formulation to overcome this limitation, we developed a GLP-1 entrapped microspheres to achieve(More)
Porcine parvovirus (PPV) can cause reproductive failure in swine, resulting in economic losses to the industry. Antiviral effects of diammonium glycyrrhizinate (DG) have been reported on several animal viruses; however, to date it has yet to be tested on PPV. In this study, the antiviral activity of DG on swine testis (ST) cell infection by PPV was(More)
A key virulence trait of Candida albicans is its ability to undergo the yeast-to-hyphal growth transition in response to environmental signals. This transition critically requires a rapid activation of the adenylyl cyclase Cyr1 to generate a cAMP spike. However, the identity of the signal sensors and mechanisms of signal processing and integration remain(More)
Chaos-based image cipher has been widely investigated over the last decade or so to meet the increasing demand for real-time secure image transmission over public networks. In this paper, an improved diffusion strategy is proposed to promote the efficiency of the most widely investigated permutation-diffusion type image cipher. By using the novel(More)
Breast cancer stem cells (BCSCs), which can fully recapitulate the tumor origin and are often resistant to chemotherapy and radiotherapy, are currently considered as a major obstacle for breast cancer treatment. To achieve the goal of both targeting BCSCs and bulk breast cancer cells, we developed 8-hydroxyquinoline-loaded hyaluronan modified mesoporous(More)
– This paper investigates the benefits of Dynamic Spectrum Management (DSM) in terms of reducing the power consumption and improving the data rates in digital-subscriber-line (DSL) networks. The proposed techniques at the three different DSM levels simultaneously also provide a significant improvement in the stability of DSLs. The proposed DSM methods are(More)
The purpose of this study was to develop poly(lactide-co-glycolide) (PLGA) based in situ forming implants (ISFI) for controlled release of thymosin alpha 1 (Talpha1). The ISFI was prepared by dissolving PLGA in N-methyl-2-pyrrolidone (NMP) or mixtures of NMP and triacetin. Talpha1 microparticles, prepared by spray-freeze drying method with chitosan or(More)
The objective of this work was to develop and evaluate a floating-pulsatile drug delivery system intended for chronopharmacotherapy. Floating-pulsatile concept was applied to increase the gastric residence of the dosage form having lag phase followed by a burst release. To overcome limitations of various approaches for imparting buoyancy, we generated the(More)
