We investigated the location, physiology, and modulation of an identified synapse from the central nervous system (CNS) of the mollusk Lymnaea stagnalis. Specifically, the excitatory synapse from interneuron right pedal dorsal one (RPeD1) to neurons visceral dorsal two and three (VD2/3) was examined. The gross and fine morphology of these neurons was determined by staining with Lucifer yellow o...

Morin (2',3,4',5,7‑pentahydroxyflavone), a flavonoid isolated from members of the Moraceae family and leaves Cudranaia tricuspidata Buread, is well‑known natural substance with anti‑inflammatory, antioxidative, antimetastasis, anticancer effects. However, its activity has not been comprehensively investigated in human epidermal growth factor receptor 2 (HER2)‑overexpressing breast canc...

Abstract: Aim: Finding out the biological sources is essential for pharmaceutical field. Materials and Methods: Endophytic fungus was isolated from Catharanthus roseus originated in Vietnam then identified by comparing, phylogeny analyzing its 18S sRNA sequence using Blast search GenomeNet. The supernatant sonicated mycelia were fractionated with methanol, ethyl acetate, hexane. All fractions u...

The aim of the study was to characterize the chemical composition and biological properties of the essential oil from the plant Lippia citriodora grown in Greece. The essential oil volatiles were analyzed by gas chromatography-mass spectrometry GC-MS indicating citral as the major component. Τhe antimicrobial properties were assayed using the disk diffusion method and the minimum inhibitory and...

In the search for novel chemotherapeutic agents for cancer treatment, capsaicin has been shown to inhibit proliferation and induce apoptosis in various types of cancer cell line, including leukaemia cell lines. The capsaicin analogues, rinvanil and phenylacetylrinvanil (PhAR), share a binding affinity for vanilloid receptors and may have biological activities similar to capsaicin; however, thei...

Curcumin, a natural compound and ingredient in curry, has antiinflammatory, antioxidant, and anticarcinogenic properties. Previously, we reported that curcumin abrogated influenza virus infectivity by inhibiting hemagglutination (HA) activity. This study demonstrates a novel mechanism by which curcumin inhibits the infectivity of enveloped viruses. In all analyzed enveloped viruses, including t...

Resilon is a new material that is a candidate to replace gutta-percha as a root filling material. This study evaluated the antiproliferative effect of Resilon and two commercially available gutta-percha points (Roeko, Dentsply). Two established cell lines (L929 and RPC-C2A) were used for the experiment. Cell survival fraction was estimated by the sulforhodamine-B assay, in reference to controls...

Multi-photon fluorescence microscopy (MPFM) is a powerful technique for imaging scattering, biological specimens in depth. In addition to the sectioning effect generated by the point-like excitation volume, the near-infrared wavelengths used for multi-photon excitation allow deeper penetration into optically turbid specimens. In physiological specimens, the optical properties such as the scatte...

BACKGROUND A decoction composed of Adenanthera pavonina L. and Thespesia populnea L. is currently being used in the treatment of cancer patients. METHODS Lactate Dehydrogenase (LDH) release, (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) MTT, and Sulforhodamine B (SRB) assays were carried out to study cytotoxicity and anti-proliferative activity against the HEp-2 cells, 24 h...

Aptamers are short, single-stranded nucleic acids that fold into well-defined three dimensional (3D) structures that allow for binding to a target molecule with affinities and specificities that can rival or in some cases exceed those of antibodies. The compatibility of aptamers with nanostructures such as thin films, in combination with their affinity, selectivity, and conformational changes u...
