Differentiating M1- and M2-Macrophages

According to the World Health Organization (WHO), toddlers and children at pre-school age have the highest prevalence of anaemia, constituting 47.4% of their population group. This prevalence is largely because of poor nutritional choices.

			Cilia and Flagella in Eukaryotes Across all species, directed movement is essential for nutrient acquisition, energy harvesting, and the avoidance of danger or sources of stress. Organisms have evolved specific means of locomotion that are complementary to the environmental conditions that they live in. For example, air, land, and water have enabled the evolution of distinct locomotive methods: namely flying, running, and swimming, respectively.

			New tool provides standards for describing characteristics and use of cell therapies Cell therapies including so-called "stem cells" are increasingly being marketed and used for the treatment of musculoskeletal disorders - despite questions about these treatments and their effectiveness. A new tool for standardizing communication about cell therapies is presented in the May 15 issue of The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.

	Mammalian Mitochondrial DNA (mtDNA) Transcription There are a total of 5 multi-subunit complexes in the inner membrane of the mitochondria, all of which are involved in the process of oxidative phosphorylation that precedes ATP production. Of these, 13 subunits are encoded by mitochondrial genes (mtDNA). The mitochondrial genome is therefore vital for the production of cellular energy. Defects in this mechanism may result in a litany of mitochondrial diseases.

	Novel lung map reveals new cells responsible for asthma For the first time, researchers have mapped the different types of cells in the lungs and identified key differences between healthy airways and airways affected by asthma in a study published in Nature Medicine. The findings could help advance the discovery of new drug targets for the condition.

	Regulatory Mechanisms Involved in Gene Expression Gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. This article aims to describe the regulatory mechanisms that control gene expression in both eukaryotes and prokaryotes.

	Scientists unmask stem cell identity using gene-sequencing technology cientists from The University of Queensland's Diamantina Institute have revealed the difference between a stem cell and other blood vessel cells using gene-sequencing technology.
