The routine use of chemotherapy to control bacterial diseases in aquatic populations has resulted in the development and spread of antibiotic resistance. The inclusion of immunostimulants in fish diets (functional diets) is one of the main strategies to solve this threat. This study aimed to analyse the intestinal microbiota of cultured European sea bass (Dicentrarchus labrax) fed two functiona...

Infectious diseases and fish feeds management are probably the major expenses in the aquaculture business. Hence, it is a priority to define sustainable strategies which simultaneously avoid therapeutic procedures and reinforce fish immunity. Currently, one preferred approach is the use of immunostimulants which can be supplemented to the fish diets. Arginine is a versatile amino acid with impo...

Immunotoxicology is a relatively new field in toxicology, and is one of emerging importance, because immunotoxicity appears to contribute to the development of cancer, autoimmune disorders, allergies and other diseases. At present, there is a lack of human cell-based immunotoxicity assays for predicting the toxicity of xenobiotics toward the immune system in a simple, fast, economical and relia...

Arbor vitae (Thuja occidentalis L.) is a native European tree widely used in homeopathy and evidence-based phytotherapy. Many reviews and monographs have been published on the herbal substance's description, mode of action and clinical use. However, no comprehensive evidence-based review is available. Therefore, our aim was to search MEDLINE databases and survey manufacturers for further detail...

The manipulation of the growth characteristics of aquatic organisms constitutes a high priority for the biotechnological industry, given the expected worldwide increase in food demand and the current food shortages, especially in animal protein, for significant segments of the population. The stimulation of growth, aimed at reducing the extension of harvest cycles for aquaculture and at decreas...

The carbon clearance ability of female ddY mice was markedly reduced by feeding with a high fat-low carbohydrate (HFLC) diet for 8 weeks. The reduced clearance ability was restored by a single intraperiotoneal (i.p.) injection with heat-killed Lactobacillus casei (YIT 9018) cells (LC 9018). The i.p. injection of LC 9018 into the HFLC diet-fed mice led to a remarkable enhancement of nonspecific ...

The protein extract of Etroplus suratensis (E. suratensis) collected from Bavanisagar dam was found to be effective against all tested organisms with an inhibition zone ranging from 0.2 to 1.9 mm. When the result was compared with standard antibiotic Streptomycin, a moderate efficiency was observed. In vitro, an antibacterial assay was used to assess the efficacy of fish protein in inhibiting t...

There is considerable interest in the potential of mushrooms in modulating the immune system and/or suppressing tumor growth. Among the studied bioactive compounds in mushrooms, polysaccharides are the most important. Nontoxic fungal polysaccharides have a more important role in immunomodulating and antitumor activities which are related to their effects to act of immune effecter cells such as ...

The efficacy of a various immunotherapeutic immunisation strategies for malignant glioma brain cancer was evaluated in the syngeneic CNS-1 Lewis rat glioma model. A prototype glioma cancer vaccine, which was composed of multivalent antigens derived from allogeneic and syngeneic cells and lysates, formed the prototype preparation of antigens. These antigens reflect the autologous antigens derive...
