Optimized whole-genome CRISPR interference screens identify ARID1A-dependent growth regulators in human induced pluripotent stem cells.

Perturbing expression is a powerful way to understand the role of individual genes, but can be challenging in important models. CRISPR-Cas screens in human induced pluripotent stem cells (iPSCs) are of limited efficiency due to DNA break-induced stress, while the less stressful silencing with an inactive Cas9 has been considered less effective so far. Here, we developed the dCas9-KRAB-MeCP2 fusion protein for screening in iPSCs from multiple donors.

Chemical Composition, Antioxidant, Anticholinesterase and Anti-Tyrosinase Activities of Essential Oils of Two Species from Turkey.

species have been known as medicinal plants since ancient times, and used as tea in Mediterranean countries such as Turkey, Greece, and Spain. They are also used for the treatment of several ailments such as a cough, common cold, and gastrointestinal disorders. The aim of the present study was to perform the chemical composition, antioxidant, anticholinesterase, and anti-tyrosinase activities of the essential oils of and .

The effect of early recombinant erythropoietin and enteral iron supplementation on blood transfusion in preterm infants.

Premature infants<1500 g were randomly assigned to study and control groups. In the study group, 42 premature infants received recombinant human erythropoietin (r-Hu EPO) 750 U/kg per week subcutaneously from day 5 to 40 and enteral iron supplementation of 2 to 6 mg/kg/d beginning on day 14 provided that they were receiving at least 50% energy intake orally. In the control group, 51 infants received the same dose of enteral iron supplementation beginning at the end of the fourth week.
