Neural regulation of cancer: from mechanobiology to inflammation. [PDF]

open access: yes, 2016
Despite recent progress in cancer research, the exact nature of malignant transformation and its progression is still not fully understood. Particularly metastasis, which accounts for most cancer death, is a very complex process, and new treatment ...

Radiation Hardness Studies in a CCD with High-Speed Column Parallel Readout

open access: yes, 2007
Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying short-lived particles.

Maternal and infant infections stimulate a rapid leukocyte response in breastmilk [PDF]

open access: yes, 2013
Breastmilk protects infants against infections; however, specific responses of breastmilk immune factors to different infections of either the mother or the infant are not well understood. Here, we examined the baseline range of breastmilk leukocytes and

Inhibitory effect of various recombinant corn trypsin inhibitor variants against trypsin

open access: yesZanco Journal of Medical Sciences
Background and objective: Trypsin is best known for playing a role in enteric digestion, among the most commonly examined serine proteases. Trypsin is expressed extra-pancreatically by a number of cancer types (for instance, Ovarian cancer), and it is ...

Evolution of proton-induced defects in a cryogenically irradiated p-channel CCD [PDF]

open access: yes, 2016
P-channel CCDs have been shown to display improved tolerance to radiation-induced charge transfer inefficiency (CTI) when compared to n-channel CCDs. This is attributed to the properties of the dominant charge-trapping defect species in p-channel silicon

Electrode level Monte Carlo model of radiation damage effects on astronomical CCDs

open access: yes, 2011
Current optical space telescopes rely upon silicon Charge Coupled Devices (CCDs) to detect and image the incoming photons. The performance of a CCD detector depends on its ability to transfer electrons through the silicon efficiently, so that the signal ...

Polyphenol‐Based Biomaterials Against Cancer Radio/Chemotherapy‐Induced Intestinal Toxicity

open access: yesAdvanced NanoBiomed Research, EarlyView.
Radiotherapy/chemotherapy often causes intestinal toxicity, impairing cancer patients’ quality of life and treatment efficacy. Polyphenols protect against this injury via multiple mechanisms, but face oral use limitations. This review outlines their protective mechanisms and delivery challenges, highlighting recent oral delivery advances and future ...

On the instability and constraints of the interaction between number representation and spatial attention in healthy humans. A concise review of the literature and new experimental evidence [PDF]

open access: yes, 2016
.The relationship between number and space representation is still one of the most debated topics in studies of mathematical cognition. Here we offer a concise review of two important behavioral effects that have pointed out the use of a spatially left ...
