Bacteria supply their allies with munitions

Posted by in category: nanotechnology

Many bacteria possess molecular spear guns, which they fire at enemies and rivals, thus putting them out of action. The tips of these nano-spear guns, known as Type VI secretion system (T6SS), are loaded with toxic molecules that lead to death of their adversaries. However, sometimes close related bacteria come under fire. The team of Prof. Marek Basler, infection biologist at the Biozentrum of the University of Basel, has shown for the first time, that in contrast to their enemies the harpooned sister cells actually profit from the attack: After a T6SS injection, they are able to reuse specific proteins to produce their own spear guns. Thus the related bacterial strains help each other to enlarge their arsenal of weapons and to fight their competitors.

Bacteria harpoon their opponents — and their allies.

The T6SS is firmly attached to the bacterial cell envelop. The tiny spear with a sharp tip is surrounded by a flexible sheath. “When bacteria fire their spear guns, the sheath rapidly contracts in just a few milliseconds and ejects the spear out of the cell into by-standing bacteria,” says Basler describing the mechanism. “The attackers then recycle the harpoon proteins remaining in the cell.” In this maneuver, the bacteria also hit related bacterial strains that do the same as the attackers: They disassemble the harpoon into their protein components and reuse these for new T6SS assembly.

Device Detects Malignant Melanoma Type to Prescribe Proper Medication

Posted by in categories: biotech/medical, genetics, nanotechnology

NICE.


Scientists at the Swiss Nanoscience Institute, the University of Basel, and the University Hospital Basel have developed and have been testing a device that can screen people with malignant melanoma for a spcific genetic mutation. About half of malignant melanoma cases involve the BRAF gene that results in rapid cell division and drugs targeting this type of cancer are available. The problem is that without knowing if a patient exhibits the mutation, it is dangerous to prescribe the medications since they will not work and will only cause additional problems.

The new device was used to analyze malignant melanoma tissue samples and to find whether the relevant genetic sequence is present. It relies on microscopic cantilevers, some of which have a coating to which the particular genetic sequence sticks to. Other cantilevers have a coating without the sequence. RNA isolated from the biopsy samples was then introduced into the device and the molecules that stuck to the cantilevers made them bend. This bending can be detected, pointing to the presence of the searched for mutation.

We Might Be Getting Closer To “Immortality” Through Medical Nanotechnology

Posted by in categories: biotech/medical, computing, health, life extension, nanotechnology, neuroscience, Peter Diamandis

No shock to me.


Diamandis claimed that we are gearing towards a future possible of “interface mind-machine, where in human brain’s consciousness could be uploaded to computer and then transferred to a new body—probably a cultured in the lab. He estimates that it will just take 20–30 years to be realized.

The reality of extended life longevity to almost immortality is actually not too hard to believe these days. After all science and technology never failed to amuse us to make the once impossible possible.

Nano-lipid Particles From Edible Ginger Could Improve Drug Delivery for Colon Cancer, Study Finds

Posted by in categories: biotech/medical, food, nanotechnology, particle physics

A new tool to battle colon cancer.


Edible ginger-derived nano-lipids created from a specific population of ginger nanoparticles show promise for effectively targeting and delivering chemotherapeutic drugs used to treat colon cancer, according to a study by researchers at the Institute for Biomedical Sciences at Georgia State University, the Atlanta Veterans Affairs Medical Center and Wenzhou Medical University and Southwest University in China.

Colorectal cancer is the third most common cancer among men and women in the United States, and the second-leading cause of cancer-related deaths among men and women worldwide. The incidence of colorectal cancer has increased over the last few years, with about one million new cases diagnosed annually. Non-targeted chemotherapy is the most common therapeutic strategy available for colon cancer patients, but this treatment method is unable to distinguish between cancerous and healthy cells, leading to poor therapeutic effects on tumor cells and severe toxic side effects on healthy cells. Enabling chemotherapeutic drugs to target cancer cells would be a major development in the treatment of colon cancer.

Nano-based masks for a more comfortable radiation treatment

Posted by in categories: biotech/medical, nanotechnology

Very hopeful — Nano-based masks for a more comfortable radiation treatment.


BOSTON, Sept. 7, 2016 /PRNewswire/ — September 25–28, 2016 – Like every year, Orfit Industries will be present at the ASTRO Annual Meeting in the Boston Convention & Exhibition Center known to be the world’s most important meeting for the radiation oncology community, with more than 11,000 people attending each year. Orfit Industries invites customers, medical specialists and professionals to come to the Orfit booth (no. 2033) and try on the new generation of nano-based masks.

Compared to Efficast® masks used for head and neck immobilization, immobilization masks made from nano-enhanced thermoplastic sheets provide the patient with more comfort through a lower degree of shrinkage and therefore reduced pressure on the face during radiation therapy. The issue of mask tightness is a very common one as medication received during the radiation treatment phase may result in an increase in the volume of the patient.

In its efforts to provide a higher degree of patient comfort, Orfit Industries developed a nano-based thermoplastic material that results in thinner masks with less shrinkage. Orfit engineers have interwoven a natural material (nano clay) in the inner layers of the thermoplastic material, which resulted in a substantial improvement of its mechanical properties. Thermoplastics will shrink when they cool on the patient during the mask making process and therefore have an impact on comfort, in particular when the volume of the patient tends to increase in the course of treatment. In this context, the reduction of shrinkage by means of NANOR® is an important step forward as it provides the degree of comfort required to minimize patient movement during the delivery of the dose.
