PURPOSE: We evaluated the safety and efficacy of intranasal bremelanotide in men with erectile dysfunction who did not respond to sildenafil. MATERIALS AND METHODS: A total of 342 married men (28 to 59 years old) with erectile dysfunction who did not…

Gateways to clinical trials is a guide to the most recent trials in current literature and congresses. The data in the following tables has been retrieved from the Clinical Trials Knowledge Area of Prous Science Integrity(R), the drug discovery and d…
We focused on the therapeutic effect of the stable gastric pentadecapeptide BPC 157 and how its action is related to nitric oxide (NO) in persistent colocutaneous fistula in rats (at 5 cm from anus, colon defect of 5 mm, skin defect of 5 mm); this pe…
PURPOSE: Stable gastric pentadecapeptide BPC 157 accelerates the healing of a transected Achilles tendon and a transected quadriceps muscle. It may also be of clinical relevance as a systemic and local peptide treatment for crush injury of a major mu…
Tissue remodeling follows the initial phase of wound healing and stops inflammatory and scar-forming processes, then restores the normal tissue morphology. The human peptide Gly-(L-His)-(L-Lys) or GHK, has a copper 2+ (Cu(2+)) affinity similar to the…
This study concerning the permeability through skin barriers of copper complexes with peptides is an important part of the research on their biological activity. The transport of copper complexes through the skin is essential in treatment of dermatol…
LL-37 is an alpha-helical antimicrobial peptide of human origin. It is a 37 residue cathelicidin peptide. This paper explores the use of electrochemical methods to investigate the interaction of LL-37 with phospholipid and lipid A monolayers on a mer…
The constitutive expression of human cathelicidin LL-37 antimicrobial peptide was achieved using the methylotrophic yeast, Pichia pastoris. An LL-37 cDNA clone was amplified by PCR using human fetal cDNA library as template. The 111 bp fragment encod…
BACKGROUND AND AIMS: The human cathelicidin (LL-37) is one of the major antimicrobial peptides of the non-specific innate immune system in the intestinal tract. Altered expression has been associated with gastrointestinal disease. Recent studies demo…
Besides their microbicidal functions, human beta-defensins (hBD) and LL-37 activate different immune and inflammatory cells, and their expression is enhanced in inflamed skin and cutaneous wound sites. To protect against pathogens, the skin produces…
Cationic antimicrobial peptides (AMPs), a component of the innate immune system, play a major role in defense of mucosal surfaces against a wide spectrum of microorganisms such as viral and bacterial co-pathogens of the polymicrobial disease otitis m…
PURPOSE OF REVIEW: To review recently published studies presenting novel and relevant information on antimicrobial peptides in gastrointestinal infections. RECENT FINDINGS: Defensins and cathelicidins are important antimicrobial peptides expressed by…
PROBLEM: Our recent studies proved that menstrual discharge is exceptionally rich in bactericidal hemoglobin peptides (hemocidins). Of special interest is the behavior of hemocidins in low pH of the vagina, in different ionic strengths, and in the pr…
The action of antibacterial cathelicidin peptide CAP11 on the anandamide production from mononuclear phagocytes was examined. Lipopolysaccharide (LPS)-stimulation induced the anandamide production from macrophage-like RAW264.7, accompanied with the e…
Preterm labour is a major problem in obstetrics. Timely intervention with available treatments is hampered by the lack of a reliable test of imminent preterm delivery. Current methods of diagnosis are based on the detection of breakdown products of f…
Cationic antibacterial peptides (ABPs) are secreted in the airways and function in the first line of defence against infectious agents. They attack multiple molecular targets to cooperatively penetrate and disrupt microbial surfaces and membrane barr…
Antibiotics are designed to support host defense in controlling infection. Here we describe a paradoxical inhibitory effect of bacteriostatic antibiotics on key mediators of mammalian innate immunity. When growth of species including Escherichia coli…
Gingival innate immunity has been studied by using biopsies and normal or transformed epithelial cell monolayers. To overcome individual biological variabilities and as a physiological alternative, we have proposed using a reconstructed tissue equiva…
