The primo vascular system (PVS) in a lymph system was observed mostly in large caliber ducts around the caudal vena cava of rabbits, rats, and mice. This required a severe surgery with laparectomy and massive removal of fat tissues in the abdomen to expose the lymph vessel. In the current brief report, we presented a new method to evade these shortcomings by observing the PVS in a less large ca...

La conjetura sobre la infinitud de los primos Germain, es decir, aquellos que “si p primo, 2p + 1 también primo“, se trata en este trabajo siguiendo un enfoque novedoso. Primero observa hay número infinito números no son Germain. Por lo tanto, si cantidad Germain infinita, una biyección con todos primos.
 Sin embargo, muestra haciendo extensión a definición obtiene esa biyección. Para logr...

Even though the primo vascular system (PVS) has been observed in large caliber lymph vessels by several independent teams, the presence of the PVS in the thoracic duct has been reported by only one team, probably because reproducing the experiment is technically difficult. This brief report presents a new, relatively straightforward method, which is a simple modification of the previous method ...

Fluorescent nanoparticles (FNPs) which were injected into a tumor tissue flowed out through the blood and lymph vessels. The FNPs in blood vessels remained only in the order for few minutes while those in lymph vessels remained for a long time disappearing completely in 25 hours. We found a primo vessel inside a lymph vessel near a blood vessel, and FNPs remained in the primo vessel for longer ...

Although it was believed that the brain was incapable of regeneration after embryonic development, neurogenesis is now known to occur into adulthood. Adult neurogenesis has been demonstrated in the subventricular zone of the lateral ventricles and the subgranular zone of the dentate gyrus of the hippocampus. Acupuncture has long been used to treat neurologic conditions, and recent reports sugge...

The aim of this study is to determine inter-laboratory variability on embryo assessment using time-lapse platform and conventional morphological assessment. This study compares the data obtained from a pilot study of external quality control (EQC) of time lapse, performed in 2014, with the classical EQC of the Spanish Society for the Study of Reproductive Biology (ASEBIR) performed in 2013 and ...
