Microbial communities in placentas from term normal pregnancy exhibit spatially variable profiles

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Ecological restoration alters microbial communities in mine tailings profiles.

Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings. In this study, microbial communities along a 60-cm profile were ...

Developing SSU rDNA metagenomic profiles of aquatic microbial communities

Five water samples from three sources, two municipal reservoirs in central North Carolina and Toolik Lake in Alaska, were processed to conduct a comparative survey of microbial small subunit rDNA sequences. Genomic DNA was extracted and amplified by PCR using universal SSU rDNA primers to generate 16S and 18S rDNA clone libraries and 50 clones from each library were sequenced and placed in oper...

Altered expression of mTOR and autophagy in term normal human placentas.

Mammalian target of rapamycin (mTOR) and autophagy have been implied in trophoblast cells proliferation and invasion. This study investigated whether mTOR and autophagy were involved in placental development and fetal programming. A total of 90 term normal placentas (37-42 gestational weeks) were collected from women who underwent elective cesarean section, with large for gestational age (LGA),...

dna flow cytometric analysis in variable types of hydropic placentas

background: differential diagnosis between complete hydatidiform mole, partial hydatidiform mole and hydropic abortion, known as hydropic placentas is still a challenge for pathologists but it is very important for patient management. objective: we analyzed the nuclear dna content of various types of hydropic placentas by flowcytometry. materials and methods: dna ploidy analysis was performed i...
