Truffle Cultivation

The role of small mammal mycophagy as vectors of hypogeous fungi is well established. However, little is known about dispersal of gourmet truffle species by mammal vectors, or about the potential role of mycophagy in truffle plantations. We hypothesize that small mammal mycophagy contributes to the productivity of truffle plantations by providing inoculum for truffle mycelium establishment and mating. Spread of non-desired competitors of gourmet truffles is a potential adverse effect of small mammal mycophagy.

Proliferation And Invasion

One hallmark of cancer is the degradation of the extracellular matrix (ECM), which is caused by proteinases. In oral cancers, matrix metalloproteinases (MMPs), especially MMP-9, are associated with this degradation. MMPs break down the ECM allowing cancer to spread; they also release various factors from their cryptic sites, including cytokines. These factors modulate cell behavior and enhance cancer progression by regulating angiogenesis, migration, proliferation, and invasion. The development of early metastases is typical for oral cancer, and increased MMP-9 expression is associated with a poor disease prognosis. However, many studies fail to relate MMP-9 expression with metastasis formation. Contrary to earlier models, recent studies show that MMP-9 plays a protective role in oral cancers. Therefore, the role of MMP-9 is complicated and may fluctuate throughout the different types and stages of oral cancers.

Myelosuppression by doxorubicin is a life-threatening adverse effect in cancer patients undergoing chemotherapy. Methyl gallate is an antioxidant found in a variety of plant species. The study aimed to demonstrate the protective role of methyl gallate on doxorubicin-induced cytopenias in Wistar rats. The animals were prophylactically treated with two different doses of methyl gallate (150mg/kg/day and 300mg/kg/day) orally for seven days. Doxorubicin (25mg/kg; single dose) was administered through intraperitoneal route on the seventh day to induce cytopenias. Blood was collected 24 hours after the administration of doxorubicin and complete blood counts were estimated. There was significant (p≤0.05) development of peripheral cytopenias in doxorubicin treated control rats compared to normal saline treated control rats. Methyl gallate at both the doses significantly (p≤0.05) mitigated doxorubicin induced cytopenias compared to doxorubicin treated control rats. The findings of the present study revealed that methyl gallate has protective role in doxorubicin-induced cytopenias in Wistar rats. Following clinical studies, methyl gallate may serve as a viable alternative to growth factors in patients undergoing chemotherapy.

Nutrition is crucial for the management of patients affected by chronic kidney disease (CKD) to slow down disease progression and to correct symptoms. The mainstay of the nutritional approach to renal patients is protein restriction coupled with adequate energy supply to prevent malnutrition. However, other aspects of renal diets, including fiber content, can be beneficial. This paper summarizes the latest literature on the role of different types of dietary fiber in CKD, with special attention to gut microbiota and the potential protective role of renal diets. Fibers have been identified based on aqueous solubility, but other features, such as viscosity, fermentability, and bulking effect in the colon should be considered. A proper amount of fiber should be recommended not only in the general population but also in CKD patients, to achieve an adequate composition and metabolism of gut microbiota and to reduce the risks connected with obesity, diabetes, and dyslipidemia.

scholarly journals Detection of group B streptococcal antibodies in human sera by radioimmunoassay: concentrations of type-specific antibodies in sera of adults and infants infected with group B streptococci

Current interest in determining the possible protective role of antibodies against group B streptococcal disease prompted this study of the feasibility of using a radioimmunoassay to measure type-specific immunity in humans. The radioimmunoassay was standardized as a quantitative test for antibodies against the carbohydrate (CHO) antigens of all five group B types. The data showed that the CHO antigens extracted by a cold trichloroacetic acid-sonification method measure more antibodies than do the corresponding CHO antigens extracted by hot hydrochloric acid; that the Ia CHOs extracted from two different types, Ia and Ic, measure the same quantity of Ia antibodies; and that human sera contain antibodies reactive with all five type-specific CHOs. No evidence of "protective" antibody was found in the serum samples studied, although there was evidence of and antibody response in adults to prolonged colonization by group B streptococci. The wide ranges of antibody concentration in a serum bank collection, the broad reactivity of all human sera tested, and the mixed populations of antibodies in human sera that react with different determinants on the same type-specific CHO antigen (type III) indicate that further studies must be done to better define normal and susceptible populations and to determine antigenic components important in protection.
