A common presenting feature is a painless enlargement of superficial lymph nodes, but also systemic symptoms (fever, weight loss, night sweats) or signs due to tumor masses expanding in the mediastinum or the abdomen or infiltrating extrahematopoietic sites (e.g., gastrointestinal tract, skin, central nervous system) may occur.
During their helium-burning phase, very high-mass stars with more than nine solar masses expand to form red supergiants.
Typical imaging findings include polypoid intraluminal fungating mass expanding the rectum without obstruction.
Prior to cell division, mitochondrial mass expands largely for two reasons.
Moreover, it revealed lytic destructions of the posterior margins of both adjacent vertebral bodies and showed an intraspinal soft tissue mass expanding between Th2 and Th5.
In early mammalian embryos following implantation of the blastocysts, the inner cell mass expands, and induction of GATA6 determines differentiation into primitive endoderm (Cai et al., 2008), which subsequently forms visceral and parietal endoderm.
After completing radiation and concurrent temozolomide, the patient's MRI demonstrated only slight linear enhancement and continued to show a stable T2 signal mass expanding into the splenium of the corpus callosum.
This approach is different from that used in the study by Rieck et al., which focused on the last third of gestation when the effective functional beta cell mass expands most dramatically [ 22].
Although information on growth control in the human pancreas remains scarce, autopsy-based studies suggest that β-cell and exocrine mass expand with distinct kinetics during childhood (Meier et al., 2008), supporting the hypothesis that proliferation in these compartments is controlled by different mechanisms.
Open image in new window Fig. 1 Mass spectra of Shengli-CGO from positive- and negative-ion ESI FT-ICR MS. Insets show the mass scale expanded mass spectra.
