Essential role of a conserved nitrogen phosphotransferase system in rhizobium-legume symbiosis

The overuse of chemical nitrogen fertilizer in agriculture has caused serious environmental issues around the world. Legume crops play important roles in sustainable agriculture and are characterized by their ability of forming nitrogen-fixing nodules, in which rhizobia

Lyme disease causing Borrelia are genetically distinct from their relapsing fever causing cousins

Lyme disease, a tick-borne infection caused by the bacterium Borrelia burgdorferi and its relatives, is currently the most prevalent vector-borne disease in North America and temperate regions of Eurasia. Increasing temperatures have expanded the habitat range for

Polyfunctional T cells induced potent anti-tumor efficacy

Adoptive T cell therapy is a form of cancer immunotherapy using T cells to target cancer cells.  In adoptive T cell therapy, white blood cells are collected from cancer patients, T cells (CD4+ and CD8+ cells) within

Drugs and drowning

Electrical activity of the heart is commonly monitored by the electrocardiogram (ECG).   Such electrical activity depends on certain proteins called ion channels.  These channels control the timing and the flow of electrically charged particles (ions) in and

Contamination of newly built thermal plants – does water hold the answer?

A domestic central heating system uses a boiler, powered by electric or gas, to heat water. This is then pumped around the system to radiators that heat a room by radiation and convection. The heat transfer fluid

Why blood donors lapse or reduce their donation’s frequency?

Finding effectives ways to retain blood donors is crucial. Four percent of Quebec (Canada) citizens are registered in the province’s blood bank. Only 6% of blood donors are registered as apheresis donors, but they supply 15% of

Relativity: Relatively uninteresting for chemists?

The periodic table of elements is among the corner stones of chemistry. In the given order, in both the periods (rows) and groups (columns), elements show some specific properties. However, when going around the bottom of the

Phthalate exposure and depression in an elderly population

Phthalates are chemicals used to increase the flexibility and softness of plastics or preserve the scent in various personal care products. They are included in a wide range of products such as food packaging, medical devices, children’s

Hepatocellular carcinoma (HCC) is a common form of malignant liver tumor and one of the leading causes of death all over the world. As for other types of cancer, many drugs have been developed and tested with

Promises and challenges in the engineering of nanosized active pharmaceutical ingredients

The advances in the field of nanotechnology have revolutionized the field of delivery of poorly soluble active pharmaceutical ingredients (APIs). Nanoparticles refer to solid colloidal three-dimensional particles in the size range from (1 to 1000) nm. Therapeutically,
