Somatostatin is a peptide hormone that exerts antisecretory and antiproliferative activities on some human tumors. The Ku70/86 heterodimer acts as regulatory subunit of the DNA dependent protein kinase and its DNA binding activity mediates DNA double stra... see more

Over the last decades, there has been an explosion of interest in plasmid DNA for gene therapy with reports of their efficacy in the fight against cancer, vascular diseases, and inherited diseases caused by specific gene defects (Srivastava, 2003). DNA pl... see more

Blood flow to the hindbrain, via the paired vertebral arteries, must be uncompromised for adequate neurological functioning of its vital centres. Therefore, it would seem unlikely that the intracranial vertebral artery would need to vasoconstrict, thus re... see more

The expression of several neuronal intermediate filament (NIF) proteins was investigated in the tongue of metamorphosing tadpoles (stage 38-45 of Gosner) and in adult individuals of the frog, Rana esculenta by means of immunohistochemistry. Results showed... see more

Sequences resembling those of human enterovirus type B sequences have been associated with motor neurone disease/ amyotrophic lateral sclerosis. In a previous study we detected enteroviral sequences in spinal cord/brain stem from cases of motor neurone di... see more

The use of a polyclonal antiserum specific to C-terminal tetrapeptide amide of (D-Ala2)deltorphin-I, a naturally occurring amphibian skin opioid peptide, has already demonstrated the presence of immunoreactive neurons in rat midbrain. Double immunostainin... see more

Nitric oxide (NO) is acknowledged as a messenger molecule in the nervous system with a pivotal role in the modulation of the chemosensory information. It has been shown to be present in the optic lobes of several insect species. In the present study, we u... see more

The aim of this study was to introduce a combined fluorescent staining that clearly demonstrates capillaries and distinguishes them from the basal lamina of muscle fibres in skeletal muscle tissue. The triple staining with CD31, Griffonia (Bandeira) simpl... see more

Our previous electron microscope study showed that chondrocytes from cephalopod cartilage possess a highly developed cytoskeleton and numerous cytoplasmic processes that ramify extensively through the tissue. We have now carried out a light microscope imm... see more

Respiratory failure resulting frequently in death is one of the complications in the course of post-hemorrhagic changes. A systemic inflammatory reaction plays a significant role in the pathogenesis of this syndrome. Mast cells also contribute to this eff... see more

Elastofibroma dorsi is a pseudotumoral fibroproliferative lesion characterized by polymorphic fiber-like deposits of elastinophilic material. Several theories have been reported explaining the pathogenesis of elastofibroma. Recent cytogenetic studies have... see more

This study was carried out on the sea bass (Dicentrarchus labrax) to follow, during development, the appearance and distribution of substance P (SP) and vasoactive intestinal peptide (VIP), which act on gut motility. The results suggest that SP and VIP pl... see more

We localized HCV C-100 protein in liver biopsies of 15 patients with chronic hepatitis C using immunohistochemistry. The results were compared to serum, tissue extract analysis of HCV RNA and in situ RT-PCR described in a previous study. HCV was detected ... see more

In this study we have investigated, by combining microbial and microscopical techniques, the adhesion ability of bacteria present in Tuber borchii ectomycorrhizosphere. Our data demonstrate that a common pool of bacteria — Pseudomonas, Bacillus, Micrococc... see more

Defensins are a family of host defence peptides that play an important role in the innate immunity of mammalian and avian species. In humans, four b-defensins have been isolated so far, corresponding to the products of the genes DEFB1 (h-BD1, GenBank acce... see more
