Cyanobacteria: Can a Toxic Foe Become a Therapeutic Friend?
ثبت نشده
چکیده
In the last five year our research group have been starting to explore the unique and extremely different cyanobacteria world, a group of Gram-negative photosynthetic bacteria, able to inhabit any kind of water environment, such as coastal and inland waters. Their name derives from the capacity to produce, during their photosynthetic processes, a blue-green coloured pigment, called c-phycocyanin (CPC). Cyanobacteria are interesting from two different points of view: they have a broad ecological impact that reflects on human and animal health. In fact, in some conditions some species of cyanobacteria extensively blooms and produce secondary metabolites toxic for humans called cyanotoxins that can affect health in humans and animals. It is now well demonstrated that these blooms are increasing during recent decades due to eutrophication of the waters, related to human activities.

Apocrine Metaplasia in Intraductal Papilloma with Foci of DCIS: A Friend or Foe?
Malignant papillary neoplasms of the breast comprise a number of microscopically distinct lesions, where apocrine metaplasia is commonly found in papillomas compared to other papillary lesions including papillary carcinomas. However, association of apocrine metaplasia in papilloma with Ductal Carcinoma in Situ (DCIS) is not very well defined. The lesions with apocrine metaplasia are not only di...

From Friend to Foe: Toxicity Trade-Offs Govern Staphylococcus aureus Infection Severity
The life-threatening human pathogen Staphylococcus aureus experiences an evolutionary tug-of-war between highly toxic strains, which are better able to transmit between hosts and less toxic strains which are better at infecting a single host. Read the Research Article.

EAAT2 to mop up excess glutamate from extracellular space. Accumulation of the neurotransmitter can be toxic to myelin-making oligodendrocytes. After spelling out the pathway in astrocyte in vitro assays, the team examined human tissue. Sure enough, NMO lesions along cadaver spines lacked both aquaporin-4 and EAAT2. Lesions from MS patients show no such deficiencies, highlighting another way in...
