Dermal papilla (DP) plays important roles in hair follicle regeneration. Long-term culture of mouse DP cells can provide enough cells for research and application of DP cells. We optimized the culture strategy for DP cells from three dimensions: stepwise dissection, collagen I coating, and optimized culture medium. Based on the optimized culture strategy, we immortalized primary DP cells with S...

introduction: penile agenesis (pa) and diphallus (dp) are extremely rare genital anomaly in children. numerous associated anomalies have been described with these malformations. these patients need several investigations and finally surgical intervention.   material & methods: in a retrospective study, 14 patients who were treated for phallus malformation in mofid children’s hospital from janua...

The non-Abelian nature of QCD suggests that particles that have a gluon constituent, such as glueballs or hybrids, should exist. Experiments WA76, WA91 and WA102 have performed a dedicated search for these states in central production using the CERN Omega Spectrometer. Several non-qq candidates have been observed. This paper presents a study of central meson production as a function of the diff...

Tests of grating acuity often underestimate amblyopia and underrefer esotropic infants with a fixation preference. To evaluate the effect of the large grating field used in preferential looking (PL) procedures, an eight-alternative, small field (about 1 degrees) grating acuity test was devised. Gratings contained at least eight cycles. Thirty-seven strabismic and/or anisometropic amblyopes, age...

It has been reported that breastfeeding can expose newborns to dechlorane plus (DP), but transplacental transfer of DP has not been documented. We measured DP and its dechlorinated analogs in matched maternal blood-placenta-cord blood samples from 72 residents of the e-waste recycling area of Wenling, China. DP was detected in cord sera, indicating the occurrence of prenatal DP exposure and the...

Dissolved phosphorus (DP) can be released from wetlands as a result of flooding or shifts in water column concentrations. Our objectives were to determine the long-term (1460 d) DP retention and release characteristics of an in-stream wetland, and to evaluate how these characteristics respond to flooding, draining, and changes in DP concentrations. The studied in-stream wetland drains an agricu...
