The gene encoding the precursor to stinging nettle (Urtica dioica L. ) isolectin I was introduced into tobacco (Nicotiana tabacum). In transgenic plants this precursor was processed to mature-sized lectin. The mature isolectin is deposited intracellularly, most likely in the vacuoles. A gene construct lacking the C-terminal 25 amino acids was also introduced in tobacco to study the role of the ...

Objective . The aim of the study was to evaluate effect medicinal plant extracts on insulin sensitivity in model diabetes mellitus. Material and Methods Experiments were carried out using 110 outbred white male rats. Diabetes mellitus induced by administration streptozotocin animals receiving food with a high fat content for formation resistance. injected metformin, rosiglitazone, aqueous nettl...

Research on the effects of declining abundances of the Eastern oyster (Crassostrea virginica) in Chesapeake Bay and other estuaries has primarily focused on the role of oysters in filtration and nutrient dynamics, and as habitat for fish or fish prey. Oysters also play a key role in providing substrate for the overwintering polyp stage of the scyphomedusa sea nettle, Chrysaora quinquecirrha, wh...

BACKGROUND Increase in the emergence of drug -resistant pathogens led to the development of natural antimicrobials. In this study the antimicrobial effect of methanolic extracts of Sambucus ebulus and Urtica dioica on 16 skin and wound infections isolates of methicillin resistant S. aureus have been studied. MATERIAL AND METHODS Solvent extraction procedure was done using soxhlet apparatus fo...

Growing environmental concerns are becoming significant challenges for large-scale applications in the automotive industry. Replacing and hybridizing glass fibers with natural non-structural is one effective way to address this challenge, while retaining useful properties of both. This paper investigates mechanical damping performance four types compression-molded materials: polyester matrix (r...

Allelopathy is a biological phenomenon of synthesizing and excreting compounds that can affect the growth various organisms, i.e., plant species. The aim this work was to investigate possible allelopathic influence aqueous extracts, obtained from species chia (Salvia hispanica L.), black cumin (Nigella sativa wormwood (Artemisia absinthium nettle (Urtica dioica on seed germination morphometric ...

Bipod nettle Utrica dioica L has therapeutic properties in treatment of human chronic diseases such as anemia, joints pain and skin diseases. In this research the major components of extracts in different parts of plant (root, stem and leaf) were identified by gas chromatography (GC) apparatus. Twenty compounds were identified, the most important of which were Neophytadiene (25.21%), Phtaleic a...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Benign Prostatic Hyperplasia (BPH) is a common disease observed in 90 percent of men over 60 (1). Benign prostat-ic hyperplasia is the most common benign tumor in men (2). The exact cause of this disease is still unknown, and environmental and genetic causes are thought to...
