An important aspect of orthopedic implant integration is the enhancement of functional activity of osteoblasts at the tissue-implant interface without any fibrous tissue intervention. Nanostructured implant surfaces are known to enhance osteoblast activity. Previously, we have reported a simple hydrothermal method for the fabrication of non-periodic nanostructures (nanoscaffold, nanoleaves and ...

We have visualized the relationship between the endoplasmic reticulum (ER) and Golgi in leaf cells of Nicotiana clevelandii by expression of two Golgi proteins fused to green fluorescent protein (GFP). A fusion of the transmembrane domain (signal anchor sequence) of a rat sialyl transferase to GFP was targeted to the Golgi stacks. A second construct that expressed the Arabidopsis H/KDEL recepto...

Silybum marianum (L.) Gaertn. is an important medicinal plant of family Compositae, commonly known as Milk-thistle, or St. Mary’s thistle. The plant and its extracts are reported to possess hepatoprotective, antioxidant, [1] anticancer, [2] antiinflammatory and antidiabetic properties. It contains flavonolignan Silymarin, which is an important bioactive principle having anticancer, antiinflamma...

The young leaves of Vernonia amygdalina are often utilized as vegetable and for medicinal purpose compared to the old leaves. This study was designed to evaluate and compare the antidiabetic effects between ethanolic leaf extracts of old and young V. amygdalina on streptozotocin (STZ) induced diabetic rat for four weeks. Preliminary screening of both young and old ethanolic extracts revealed th...

The aim of the present study is to investigate the possible protective effect of dry olive leaf extract (OLE) against acetic acid-induced ulcerative colitis in rats, as well as the probable modulatory effect of nitrergic and opioidergic systems on this protective impact. Olive leaf extract was administered (250, 500 and 750 mg/kg) orally for two successive days, starting from the colitis induct...

Cancers are the uncontrolled growth of cells or tumors, and it is one leading causes death all over world. Currently, available synthetic drugs such as cisplatin, doxorubicin fluorouracil reported to have notable side effects in living tissues (skin irritations, dry cracked skin, mouth sores). So researchers scrutinizing for alternative medications overcome these effects. Plants vital sources m...

OBJECTIVE The aim of this study was to investigate the antioxidant activity of extracts of various parts of Acanthopanax trifoliatus obtained by different extraction methods. The total phenolic and flavonoid contents of the extracts were also determined. MATERIALS AND METHODS The leaves, stems, stem bark, roots and root bark of A. trifoliatus were extracted separately using decoction, macerat...

Objective: The present study was undertaken to evaluate the aqueous extract of K. pinnata for its protective effects on gentamicin-induced nephrotoxicity in rats. Materials and Methods: Nephrotoxicity was induced in Wistar rats by intraperitoneal administration of gentamicin 100 mg/kg/day for eight days. Effect of concurrent administration of K. pinnata leaf extract at a dose of 125 mg/kg/day g...

In a search for an analogue of AAL-toxin with high phytotoxicity and low mammalian toxicity, aminopentols [(AP1), hexacetyl AP1 and N-acetyl AP1], and nine analogues (1-9), were tested for toxicity to duckweed (Lemna pausicostata), susceptible tomato (asc/asc) leaf discs, black nightshade leaf discs and mammalian cell lines, including dog kidney (MDCK), rat liver hepatoma (H4TG) and mouse fibro...
