Blocking Tyr265 nitration of protein phosphatase 2A attenuates nitrosative stress-induced endothelial dysfunction in renal microvessels.

FASEB J 2018 Dec 6:fj201800885RR. Epub 2018 Dec 6.

Division of Nephrology, Department of Internal Medicine, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Protein tyrosine (Tyr) nitration, the covalent addition of a nitro group (NO) to Tyr residues, is emerging as a candidate mechanism of endothelial dysfunction. Previous studies have shown that Tyr nitration is primarily induced by nitrosative stress, a process characterized by the production of reactive nitrogen species, especially peroxynitrite anion (ONOO), which is considered a secondary product of NO in the presence of superoxide radicals (O). However, the impact of nitrosative stress-induced Tyr nitration on endothelial dysfunction has not been thoroughly elucidated to date. Read More

Sci Rep 2018 Dec 5;8(1):17641. Epub 2018 Dec 5.

Laboratory of Drug Delivery Systems, Faculty of Pharmaceutical Sciences, Kobe Gakuin University, 1-1-3 Minatojima, Chuo-ku, Kobe, Hyogo, 650-8586, Japan.

In a recent study, we demonstrated the potential of a cell-penetrating peptide (CPP) penetratin to deliver the peptide drug insulin to the brain via nasal administration, and its pharmacological effect on the mild cognitive dysfunction in senescence-accelerated mouse (SAMP8). However, the therapeutic potential of intranasal insulin administration was attenuated when applied to the aged SAMP8 with severe cognitive dysfunction. The present study, therefore, aimed to overcome the difficulty in treating severe cognitive dysfunction using insulin by investigating potential alternatives, glucagon-like peptide-1 (GLP-1) receptor agonists such as exendin-4.

Benign outcome of penetrating and posterior keratoplasty depends on viability of the corneal tissue and presence of the proper endothelial layer, which retaining is one of the main objectives of preservation of donor material. Methods designed to reach this goal may be classified according to storage duration as short-term (storage in a moist chamber), medium-term (hypothermia), long-term (organ cultivation) and unlimited (cryopreservation).

Antibiotics-Peptide Conjugates Against Multidrug-Resistant Bacterial Pathogens.

Curr Top Med Chem 2018 Nov 29. Epub 2018 Nov 29.

Center for Targeted Drug Delivery, Department of Biomedical and Pharmaceutical Sciences, Chapman University School of Pharmacy, Harry and Diane Rinker Health Science Campus, 9401 Jeronimo Road, Irvine, California 92618-1908. United States.

The menace of multi-drug resistance by bacterial pathogens that are responsible for infectious diseases in humans and animals cannot be over-emphasized. Many bacteria develop resistance to antibiotics by one or more combination of resistance mechanisms namely, efflux pump activation thereby reducing bacteria intracellular antibiotic concentration, synthesizing a protein that protects target site causing poor antibiotic affinity to the binding site, or mutations in DNA and topoisomerase gene coding that alters residues in the binding sites. The ability to use a combination of these resistance mechanisms among others create a phenomenon known as antimicrobial drug resistance. Read More

Therapeutic nanoplatforms and delivery strategies for neurological disorders.

Nano Converg 2018 Nov 30;5(1):35. Epub 2018 Nov 30.

The major neurological disorders found in a central nervous system (CNS), such as brain tumors, Alzheimer's diseases, Parkinson's diseases, and Huntington's disease, have led to devastating outcomes on the human public health. Of these disorders, early diagnostics remains poor, and no treatment has been successfully discovered; therefore, they become the most life-threatening medical burdens worldwide compared to other major diseases. The major obstacles for the drug discovery are the presence of a restrictive blood-brain barrier (BBB), limiting drug entry into brains and undesired neuroimmune activities caused by untargeted drugs, leading to irreversible neuronal damages.

Targeted drug delivery using iRGD peptide for solid cancer treatment.

Mol Syst Des Eng 2017 Oct 16;2(4):370-379. Epub 2017 Aug 16.

Department of Medicine, Division of NanoMedicine, University of California, Los Angeles, CA, USA.

Many solid tumor types, such as pancreatic cancer, have a generally poor prognosis, in part because the delivery of therapeutic regimen is prohibited by pathological abnormalities that block access to tumor vasculature, leading to poor bioavailability. Recent development of tumor penetrating iRGD peptide that is covalently conjugated on nanocarriers' surface or co-administered with nanocarriers becomes a popular approach for tumor targeting. More importantly, scientists have unlocked an important tumor transcytosis mechanism by which drug carrying nanoparticles directly access solid tumors (without the need of leaky vasculature), thereby allowing systemically injected nanocarriers more abundantly distribute at tumor site with improved efficacy.

In this case, a 22-year-old man sustained multiple gunshot wounds to the abdomen, which required in extremis surgical exploration with damage control laparotomy and hemostatic resuscitation in the surgical intensive care unit. Diagnostic angiography was negative and an inferior vena cava (IVC) injury was suspected. He was returned to the operating room, where the infrarenal IVC was accessed by direct puncture and venography demonstrated active extravasation of the suprarenal vena cava. Read More
