Out of thin air – how marine bacteria beat nitrogen limitation
Nitrogen (N), one of life’s most important building blocks, is often in short supply; both on land and in the ocean (Fig. 1). This shortage means that N is often the factor limiting the growth and abundance
Genetics and dietary stress explain low calcium absorption
It is well understood that osteoporosis is influenced by a variety of environmental factors such as age, nutrition, and race. Calcium absorption is one of these important factors and low levels of calcium absorption have been associated
Going my way? A tale of enzyme recruitment and activation
蛋白质合成是一个大力cellu付出高昂的代价lar process, in part due to the metabolic requirements of ribosome assembly and gene-specific messenger RNA (mRNA) production. Consequently, biosynthetic flux through the protein translation pathway is tightly regulated while translational
Specific danger signals associate with non-infection-related COPD exacerbations
慢性阻塞性肺疾病(COPD) is a progressive and chronic lung disease, leading to difficulties with breathing for the patients. This is caused by the destruction of the lung sacs (alveoli), called emphysema and by inflammation of
Catalytic carbon-carbon bond formation
A chemical reaction is the transformation of one or more reagents into one or more products that takes place at a characteristic rate depending on the energy needed to activate the process. A catalyst is a substance
ATF3-dependent cross-talk between cardiomyocytes and macrophages promotes cardiac maladaptive remodeling
Cardiovascular diseases are disorders of the heart and blood vessels which are leading to heart failure. Cardiovascular diseases correspond to 30% of all deaths in the world. The molecular processes that undergone from a healthy heart to
Reversibility of FXTAS
Fragile X-associated tremor/ataxia syndrome or FXTAS is a relatively unknown neurodegenerative disorder characterized by progressive development of tremor, ataxia, parkinsonism, and psychiatric problems. The cause of the disease is a so-called premutation in the FMR1 gene, located
Lutetium-177 radioisotope targeted therapy for treatment of cancer and other diseases
By their nature, radioactive isotopes are unstable and can change to more stable forms by radioactive decay and emission of different types of radiation. This emitted radiation is useful for cancer treatment which includes placement of “sealed”
G protein signaling: a major culprit of essential hypertension
Blood pressure (BP) is the driving force that distributes the blood to the organs of the body according to their instantanous needs. It may be increased by pressor agents acting on the heart, vessels, and blood volume,
Cerium fluoride nanoparticles protect cells against oxidative stress
Nano-biomaterials engineering is one of today’s most promising areas of materials science. In very recent years, nanocrystalline cerium oxide (nanoceria) has been shown to possess enormous biological activity, which originates from its ability to scavenge the reactive
