PURPOSE PD 0313052 is a potent, direct factor Xa (FXa) inhibitor (Ki = 0.33 nM) and its antithrombotic effect has been previously demonstrated in several animal models, via intravenous (IV) administration. In the present study, we evaluated four different subcutaneous (SC) formulations to test the feasibility of developing PD 0313052 as a subcutaneous agent. METHODS PD 0313052 was formulated ...

Despite extensive investigation over the past three decades, cancer immunotherapy has produced limited success, with few agents achieving approval by the Food and Drug Administration and even the most effective helping only a minority of patients, primarily with melanoma or renal cancer. In recent years, immune checkpoints that maintain physiologic self-tolerance have been implicated in the dow...

Background: The incidence of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in Iran is estimated at 10-14.9%.  The donor blood in blood banks is not screened routinely for this enzyme deficiency and such blood may be used for neonatal exchange transfusion.Objective: To study the effect of G-6-PD deficient blood in neonatal exchange blood transfusion.Methods: In a prospective study, serum...

Both positive and negative regulatory roles have been suggested for the B7 family member PD-L1(B7-H1). PD-L1 is expressed on antigen-presenting cells (APCs), activated T cells, and a variety of tissues, but the functional significance of PD-L1 on each cell type is not yet clear. To dissect the functions of PD-L1 in vivo, we generated PD-L1-deficient (PD-L1(-/-)) mice. CD4(+) and CD8(+) T cell r...

A facile one-pot approach for preparing hierarchical nanowire-networks of hollow polymer@Pd nanospheres is reported. First, polymer@Pd hollow nanospheres were produced through metal-complexation-induced phase separation with functionalized graft copolymers and subsequent self-assembly of PdNPs. The nanospheres hierarchically assembled into the nanowire-network upon drying. The Pd nanowire-netwo...

Plasmodione (PD) is a potent antimalarial redox-active 3-benzyl-menadione acting at low nanomolar range concentrations on different malaria parasite stages. The specific bioactivation of PD was proposed to occur via cascade redox reactions starting from one-electron reduction and then benzylic oxidation, leading the generation several key metabolites including corresponding alcohol (PD-bzol, fo...

Introduction: The aim of present study was to investigate the effects of royal jelly (RJ) on the number of Nissl-stained neurons in caudate putamen unit (CPU) and substantia nigra pars compacta (SNC) and the thickness of gray (TGm) and white matter (TWm) of cerebral and cerebellar cortex in male rats with Parkinson’s disease (PD). Methods: Seventy five Sprague-Dawley adults’ male ra...

Scientific evaluation of partial discharge (PD) severity in gas-insulation switchgear (GIS) can assist in mastering the insulation condition of in-service GIS. Limited theoretical research on the laws of PD deterioration leads to a finite number of evaluation features extracted and subjective features selected for PD severity assessment. Therefore, this study proposes a minimum-redundancy maxim...

abstract background and objective: parkinson's disease (pd) is an age-related neurodegenerative disorder with massive loss of dopaminergic neurons in the substantia nigra pars compacta. l-dihydroxyphenylalanine (l-dopa) substitution is still the gold standard therapy for pd. however, there has been little information available on neuroprotective and regenerative therapies for pd. due to the neu...

Positive ion mode matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) was used to explore nonspecific interactions between proteins and oligonucleotides. The formation of noncovalent complexes showed correlation with the type of oligonucleotide bases and with the amino acid composition of the proteins. Among the four DNA homooligomers, abundant protein-nucleic acid complexe...
