Kojic acid applications in cosmetic and pharmaceutical preparations.

Biomed Pharmacother 2018 Dec 8;110:582-593. Epub 2018 Dec 8.

Student Research Committee, Department of Pharmaceutics, Faculty of Pharmacy, Mazandaran University of Medical Sciences, Sari, Iran. Electronic address:

Skin color disorders can be caused by various factors, such as excessive exposure to sunlight, aging and hormonal imbalance during pregnancy, or taking some medications. Kojic acid (KA) is a natural metabolite produced by fungi that has the ability to inhibit tyrosinase activity in synthesis of melanin. The major applications of KA and its derivatives in medicine are based on their biocompatibility, antimicrobial and antiviral, antitumor, antidiabetic, anticancer, anti-speck, anti-parasitic, and pesticidal and insecticidal properties.

The influence of intrinsic folding mechanism of an unfolded protein on the coupled folding-binding process during target recognition.

Proteins 2018 Dec 6. Epub 2018 Dec 6.

National "111" Center for Cellular Regulation and Molecular Pharmaceutics, Hubei University of Technology, Wuhan, China.

Intrinsically disordered proteins (IDPs) are extensively involved in dynamic signaling processes which require a high association rate and a high dissociation rate for rapid binding/unbinding events and at the same time a sufficient high affinity for specific recognition. Although the coupled folding-binding processes of IDPs have been extensively studied, it is still impossible to predict whether an unfolded protein is suitable for molecular signaling via coupled folding-binding. In this work, we studied the interplay between intrinsic folding mechanism and coupled folding-binding process for unfolded proteins through molecular dynamics simulations. Read More

The Applications of 3d Printing in Pulmonary Drug Delivery and Treatment of Respiratory Disorders.

Curr Pharm Des 2018 Dec 6. Epub 2018 Dec 6.

Drug Delivery Disposition and Dynamics, Monash Institute of Pharmaceutical Sciences, Monash University, 381 Royal Pde, Parkville VIC. Australia.

Background: Pulmonary diseases are the third leading cause of morbidity worldwide, however treatment and diagnosis of these diseases continues to be challenging due to the complex anatomical structure as well as physiological processes in the lungs.

Methods: 3D printing is progressively finding new avenues in the medical field and this technology is constantly being used for diseases where diagnosis and treatment heavily rely on the thorough understanding of complex structural-physiology relationships. The structural and functional complexity of the pulmonary system makes it well suited to 3D printing technology. Read More

A critical review on 3D-printed dosage forms.

Curr Pharm Des 2018 Dec 6. Epub 2018 Dec 6.

Institute of Pharmaceutics and Biopharmaceutics, Heinrich Heine University Duesseldorf, Universitaetsstr. 1, 40225 Duesseldorf. Germany.

Background: In the last decades, 3D-printing has been investigated and used intensively in the field of tissue engineering, automotive and aerospace. With the first FDA approved printed medicinal product in 2015, the research on 3D-printing for pharmaceutical application has attracted attention of pharmaceutical scientists. Due to its potential of fabricating complex structures and geometrics, it is a highly promising technology for manufacturing individualized dosage forms. Read More

3D Printing Methods for Pharmaceutical Manufacturing: Opportunity and Challenges.

Curr Pharm Des 2018 Dec 6. Epub 2018 Dec 6.

Department of Pharmaceutics, School of Pharmaceutical Education & Research, Jamia Hamdard, New Delhi-110062. India.

Background: A recently FDA approved 3D printed drug is paving a path for new pharmaceutical manufacturing era. The 3D printing is a novel approach of producing 3D pharmaceuticals from digital designs, in a layer-by-layer fashion. However, traditional manufacturing of drug products are being carried out from decades with well-established manufacturing processes and with well approved regulatory guidelines but these processes are too obsolete in concern of process aptitude and manufacturing flexibility.

Use of Generally Recognized as Safe or Dietary Compounds to Inhibit Buprenorphine Metabolism: Potential to Improve Buprenorphine Oral Bioavailability.

Biopharm Drug Dispos 2018 Dec 5. Epub 2018 Dec 5.

Dept. of Pharmaceutics, VCU School of Pharmacy, 410 N. 12th Street, Richmond, VA, 23298.

The present study evaluated the potential of five generally recognized as safe (GRAS) or dietary compounds (α-mangostin, chrysin, ginger extract, pterostilbene and silybin) to inhibit oxidative (CYP) and conjugative (UGT) metabolism using pooled human intestinal and liver microsomes. Buprenorphine was chosen as the model substrate as it is extensively metabolized by CYPs to norbuprenorphine and by UGTs to buprenorphine glucuronide. Chrysin, ginger extract, α-mangostin, pterostilbene and silybin were tested for their inhibition of formation of norbuprenorphine or buprenorphine glucuronide in both intestinal and liver microsomes.

The mouse-canine chimeric anti-dog podoplanin antibody P38B exerts antitumor activity in mouse xenograft models.

Biochem Biophys Rep 2019 Mar 24;17:23-26. Epub 2018 Nov 24.

Department of Antibody Drug Development, Tohoku University Graduate School of Medicine, 2-1 Seiryo-machi, Aoba-ku, Sendai, Miyagi 980-8575, Japan.

Podoplanin (PDPN) is a type I transmembrane heavily glycosylated sialoglycoprotein that is expressed in normal tissues such as pulmonary type I alveolar cells, renal podocytes, and lymphatic endothelial cells. PDPN overexpression in cancerous tissue is associated with hematogenous metastasis through interactions with the C-type lectin-like receptor 2 (CLEC-2). Previously, we have reported the development of a mouse monoclonal antibody (mAb), PMab-38 (IgG, kappa) against dog PDPN (dPDPN). Read More

Investigation of tolerability and quality of life for carboplatin-based chemotherapy in an elderly urothelial carcinoma patient undergoing hemodialysis: a case report.

J Pharm Health Care Sci 2018 29;4:29. Epub 2018 Nov 29.

1Department of Pharmacy, Nagoya City University Hospital, 1-Kawasumi, Mizuho-cho, Mizuho-ku, Nagoya, Aichi 467-8602 Japan.

Background: To our knowledge, no studies have evaluated the safety of carboplatin (CBDCA)-based chemotherapy in hemodialysis patients > 80 years-old. In addition, the impact of CBDCA-based chemotherapy on such elderly patients' quality of life (QOL) is unknown. We report a case of gemcitabine plus CBDCA chemotherapy treatment in an 81-year-old man with metastatic urothelial carcinoma undergoing hemodialysis. Read More

Mitochondrial functioning abnormalities observed in blood platelets of chronic smoke-exposed guinea pigs - a pilot study.

Int J Chron Obstruct Pulmon Dis 2018 9;13:3707-3717. Epub 2018 Nov 9.

Department of Pneumology and Allergy, Medical University of Lodz, Lodz, Poland,

Background: COPD represents a major global health issue, which is often accompanied by cardiovascular diseases. A considerable body of evidence suggests that cardiovascular risk is elevated by the activation of blood platelets, which in turn is exacerbated by inflammation. As reactive oxygen species are believed to be an important factor in platelet metabolism and functioning, the aim of our study was to perform a complex assessment of mitochondrial function in platelets in chronic smoke exposed animals with COPD-like lung lesions.
