Pedophilia emerging in a 64 years old pediatrician

Everyone knows what pedophilia is, but probably only few people are aware that pedophilia might also emerge anytime in life as a consequence of brain damage. Indeed, sometimes pedophilic behavior could be observed in old people with

Microfluidic tumor models help pre-clinical screening of T cell cancer immunotherapies

Cancer immunotherapy draws upon the patient’s own immune system to recognize and fight the disease. One form of cancer immunotherapy is known as adoptive T cell therapy (ACT) consisting of isolation, genetic manipulation and reinfusion into the

Is the best cancer offense a good defense?

Although the unique DiRas (Distinct subgroup of the Ras family) family of small GTPases shares homology with the pro-oncogenic Ras GTPases, it has tumor-suppressive actions. DiRas1 (also known as Di-Ras1 or Rig) has been reported to be

Lessons learned from the study of non-cancerous meningioma tumors

Meningiomas are the most common among tumors inside the skull (35.6%). The cellular origin of these tumors is the membrane that surrounds the brain, the meninges (Fig. 1) Most meningiomas are grades I & II according to

A new test to select more effective treatments for lung cancer

Sadly, the majority of patients with Lung Cancers who cannot be treated by surgery to remove their tumour, die within a few years. Small numbers are beginning to benefit from chemotherapies which target very specific types of

Less is more for staging vaginal cancer

Criteria for predicting the survival of women with vaginal cancer has been established by physician specialists trained in treating gynecologic cancers in the United States and around the world. The current 5-year overall survival is approximately 74%

Tumor risk from low-dose radiation exposures with the example of dental diagnostic X-ray

It was reported that exposure to dental diagnostic X-rays in oral, dental and maxillofacial care increases the risk of benign tumors (meningioma), but not of malignant brain tumors (glioma). Malignant gliomas grow more rapidly. Meningioma, a benign

Atomic classification of cancer cells

Cancer cells have molecules, known as receptors, on their surface that distinguish them from healthy cells. Knowing receptors that are present on malignant cells can help to detect and/or classify the disease.  Here, we developed a method

A “TORgeted” way to heal the gut

Our intestine is critical for absorbing the dietary nutrients that we need to survive. It performs this function by producing, from pools of intestinal stem cells (ISCs), a constant stream of new cells (differentiated cells) that have

Fluorescent carbon dots integrated hydrogels for lung cancer therapy

Cancer is considered as one of the leading cause of death worldwide. Due to the ever changing lifestyle of the modern society, the incidence of cancer is on the rise. Lung cancer is the most frequently diagnosed

Nanoscintillators: magic internal light sources to assist radiotherapy

Photosensitizers are molecules that are able to produce cytotoxic species that include singlet oxygen, a particular form of oxygen that is strongly oxidizing, when they are illuminated by visible or NIR light. Because of this property, they

Is our immune system mistaking tumours for foetuses?

Tumours are abnormal growths of tissue where cells produced by the body get out of control and divide at a rapid and unregulated pace. And – when you think about it – embryos too are masses of

Improving nature’s own communication system to fight cancer

Our bodies are composed of trillions of different cells, which communicate with each other in order to keep us healthy. There are several ways in which messages can be sent back and forth between cells. One of

Heat shock protein as a novel druggable target in angiogenesis?

Angiogenesis is a physiological process that involves formation of new blood vessels from pre-existing vessels for efficiently providing oxygen and nutrients during growth and development, as well as during wound healing. Under pathological conditions, angiogenesis is regulated

Treatment holidays for patients with metastatic kidney cancer

Targeted therapy is the standard treatment of patients with metastatic cancer of the kidney. The best current therapies target the tumour vasculature thereby blocking the access of the tumour to nutrients and limiting possibility of spreading to

Emergency department presentation predicts poor outcomes after meningioma removal

A meningioma is one of the most common forms of a brain tumor. Unlike many other types of brain tumors, meningiomas are typically associated with relatively favorable outcomes even when they require surgical treatment. In the past
