Cell-penetrating peptides (CPPs) are routinely used for intracellular delivery of a variety of cargo, including drugs, genes, and short interfering RNA (siRNA). Most CPPs are active only upon exposure to acidic environments inside of late endosomes, thereby facilitating the endosomal escape of internalized vectors. Here, we describe the generation of a(More)
Intervention of the inflammation cascade with tumor necrosis factor-a (TNF-a) monoclonal antibodies or receptors represents a major approach in clinical immunotherapy against inflammatory diseases, which however, often suffers from high cost, autoimmunity to antibodies, and various side effects. [1] siRNA-mediated RNA interference (RNAi) has recently(More)
Poly(γ-4-((2-(piperidin-1-yl)ethyl)aminomethyl)benzyl-l-glutamate) (PPABLG), a cationic helical polypeptide, has been recently developed by us as an effective non-viral gene delivery vector. In attempts to elucidate the effect of molecular architecture on the gene delivery efficiencies and thereby identify a potential addition to PPABLG with improved(More)
Nefopam (NFP) is a non-opioid, non-steroidal, centrally acting analgesic drug that is derivative of the non-sedative benzoxazocine, developed and known in 1960s as fenazocine. Although the mechanisms of analgesic action of NFP are not well understood, they are similar to those of triple neurotransmitter (serotonin, norepinephrine, and dopamine) reuptake(More)
Poly(arginine) mimics bearing long hydrophobic side chains adopt a stable helical conformation and exhibit helix-related cell-penetrating properties. Elongating the polypeptide backbone length and increasing side chain hydrophobicity further increase the helicities of poly(arginine) mimics. These helical poly(arginine) mimics show superior cell membrane(More)
Nonviral gene delivery with synthetic cationic polymeric vectors is widely recognized as an attractive alternative to viral gene delivery, which suffers from inherent immunoge-nicity and various side effects. [1] The transfection efficiency and chemotoxicity of these polymeric vectors are often closely related to the density of their cationic charge. [2](More)
BACKGROUND Lidocaine patch (L5P) has demonstrated short-term efficacy in treating both acute surgical pain and chronic neuropathic pain with tolerable side effects. Percutaneous endoscopic lumbar discectomy (PELD) is the mainstay of minimally invasive spine surgery (MISS). Sufficient analgesia during PELD surgery makes the patient consider it real MISS.(More)
BACKGROUND The recently known analgesic action mechanisms of nefopam (NFP) are similar to those of anticonvulsants and antidepressants in neuropathic pain treatment. It is difficult to prescribe high doses of oral neuropathic drugs without titration due to adverse effects. Unfortunately, there are few available intravenous analgesics for the immediate(More)
Varicella (chickenpox) is a highly contagious airborne disease caused by primary infection with the varicella zoster virus (VZV). Following the resolution of chickenpox, the virus can remain dormant in the dorsal sensory and cranial ganglion for decades. Shingles (herpes zoster [HZ]) is a neurocutaneous disease caused by reactivation of latent VZV and may(More)
BACKGROUND/AIMS Pegylated interferon (peginterferon) and ribavirin combination therapy is less effective and associated with a higher frequency of serious complications in chronic hepatitis C patients with cirrhosis than in noncirrhotic patients. This study evaluated the efficacy and tolerability of peginterferon and ribavirin treatment in patients with(More)
