During plant growth, dividing cells in meristems must coordinate transitions from division to expansion and differentiation. Three distinct developmental zones are generated: the meristem, where the cell division takes place, and elongation and differentiation zones. At the same time, plants can rapidly adjust their direction...

Si los progenitores consumen alcohol, es más probable que sus hijos conduzcan bajo sus efectos. Esta es una de las conclusiones extraídas de un nuevo estudio que analiza los datos de más de 30.000 estudiantes y su relación con la bebida y la conducción. Los resultados se publican en la revista Adicciones. Fuente :...

Androstenone can stop dogs from barking, jumping, researchers report. Androstenone is produced by pigs in their saliva or fat, but Boar Mate androstenone is synthesized in a laboratory. One spray of Boar Mate on Toto was all it took to set the wheels of experimentation in motion. Fuente :...

A recent literature review found no scientific evidence that care provided by a nurse anesthetist is as safe and effective as patient-centered, physician-led anesthesia care, prompting experts to call for further examination to measure patient safety and anesthesia care delivery. Fuente :...

Scientists can now monitor and record the activity of hundreds of neurons concurrently in the brain, and ongoing technology developments promise to increase this number. However, simply recording the neural activity does not automatically lead to a clearer understanding of how the brain works. In a new article, researchers...

Der Süßwasserpolyp Hydra, der zu den mehr als 600 Millionen Jahre alten Nesseltieren gehört, ist berühmt für seine nahezu unbegrenzte Regenerationsfähigkeit und daher ein Modell der molekularen Stammzell- und Regenerationsforschung. Dieser einfache und radiär symmetrisch gebaute Polyp kann auch helfen zu verstehen, wie unsere...

The fresh-water polyp Hydra, a member of the over 600-million-year-old phylum Cnidaria, is famous for its virtually unlimited regenerative capability and hence a perfect model for molecular stem cell and regeneration research. This polyp, with its simple structure and radial symmetry, can help us understand how our body axes...

Tres avances inéditos en seis días en la negociación que el gobierno colombiano y la guerrilla comunista FARC adelantan hace casi dos años en La Habana, mientras continúa la guerra surgida en 1946.

Epidermal growth factor receptor mutations found in the circulating free tumor DNA from the plasma of advanced non-small cell lung cancer patients correlates well with the epidermal growth factor receptor mutations from patient-matched tumor tissue DNA, researchers report. Fuente :...

For the first time, an oncogenic somatic mutation at amino acid 918 in the rearranged during transfection protein has been identified in small cell lung cancer tumors and enforced expression of this mutation within small cell lung cancer tumor cell lines produced increased intracellular signaling and cell growth.

Bcl-2-like protein 11 deletion in advanced non-small cell lung cancer is associated with shorter progression free survival in epidermal growth factor receptor tyrosine kinase inhibitor or chemotherapy treated Asian patients. Also, Bcl-2-like protein 11 deletion independently predicts overall survival of advanced non-small cell...

Persons with MS may be able to improve their self-awareness through task-oriented cognitive rehabilitation, a study shows. Self-awareness is one's ability to recognize cognitive problems caused by brain injury. This is the first study of self-awareness in MS that includes assessment of online awareness, as well as metacognitive...

The application of antibiotics can be reduced in pig breeding by using antimicrobial peptides, researchers have found. Researchers investigated the application of antimicrobial peptides (AMP) as substitutes for antibiotics in liquid sperm preservation. They were able to show that AMPs fight bacteria effectively in test tubes,...

Compounds that target brain cancer have been recently developed by researchers. The team synthesized a first-of-its-kind inhibitor that prevents the activity of an enzyme called neuraminidase. Although flu viruses use enzymes with the same mechanism as part of the process of infection, human cells use their own forms of the...

Anyone who has suffered an injury can probably remember the after-effects, including pain, swelling or redness. These are signs that the body is fighting back against the injury. When tissue in the body is damaged, biological programs are activated to aid in tissue regeneration. Now, researchers...
