New Hydrogel Lab Technique Allows for Creating Precise Environments for 3D Tumor Growth
Glioma (brain cancer) cells growing in a 3-D hydrogel. The green fluorescent dye reflects the cytoskeletons of the cells. Scale bar is 50 mm. | Photo courtesy Brendan Harley Tumor growth is very much affected by its biochemical environment, but studying how all that happens requires creating special biomaterials that can sustain the growth of the tumor in three dimensions and allow for experiments to be conducted. Hydrogels have been used to grow volumes of glioma tumors in the lab, but now researchers at University of Illinois, Urbana-Champaign are reporting the development of a new technique that allows them to grow tumo...

What about this cell with red granular cytoplasm?
I'm working on a high-grade glioma and am coming across scattered presumably neoplastic cells that have course red granular cytoplasm. How does one interpret such cells? Does it raise the possibility of a granular cell astrocytoma? Or are these often present and I've just ignored them until now? Thanks for any help you might be able to provide in the comments section! (Source: neuropathology blog)

Eight Toxic Foods: A Little Chemical Education
Many people who read this blog are chemists. Those who aren't often come from other branch of the sciences, and if they don't, it's safe to say that they're at least interested in science (or they probably don't hang around very long!) It's difficult, if you live and work in this sort of environment, to keep in mind what people are willing to believe about chemistry. But that's what we have the internet for. Many science-oriented bloggers have taken on what's been called "chemophobia", and they've done some great work tearing into some some really uninformed stuff out there. But nonsense does not obey any conservation law...

Is this a nodular subcortical heterotopia- neonatal brain ultrasound
This neonate shows a large (3.5 cms.) sized lesion in the Rt. cerebral hemisphere. What do these neonatal brain ultrasound images portray? Is it a case of neonatal nodular subcortical heterotopia or is it an ICSOL due to intracerebral bleed or some form of glioma?the answer: this is a large intracerebral haematoma occupying the right parietal and occipital regions of the neonate ' s brain. This was the diagnosis based on the MRI scan.See:http://www.ultrasound-images.com/Pediatric.htm#Intracranial%20hemorrhageSee this link:Radiology (AJNR) article on disorders of cortical formation (Source: cochinblogs)

Does Having Allergies Reduce the Risk of Brain Cancer?
As anyone with seasonal allergies to tree pollen knows, allergy season has begun. Aside from the sneezing, itchy eyes, nasal congestion, and general sense of being ill, is there anything good about this springtime immune system dysfunction? I came across some evidence that might slightly relieve that annual sense of “suffering” – having allergies of any kind seems to reduce the risk of glioma, including malignant brain tumors, by up to 40%. Asthma, eczema, and hay fever seem to all have this “protective” effect. Multiple observational, case-control studies have shown that allergic conditions a...
