In-Person Contact Begets Calling and Texting: Interpersonal Motives for Cell Phone Use, Face-to-Face interaction, and Loneliness [PDF]

open access: yes, 2010
This study examined how cell-phone use is related to interpersonal motives for using cell phones, face-to-face communication, and loneliness. A survey of 232 college students who owned a cell phone revealed that affection and inclusion were relatively ...

Estimating Bacterial and Cellular Load in FCFM Imaging

open access: yesJournal of Imaging, 2018
We address the task of estimating bacterial and cellular load in the human distal lung with fibered confocal fluorescence microscopy (FCFM). In pulmonary FCFM some cells can display autofluorescence, and they appear as disc like objects in the FCFM ...

Cell-cell interactions in synovitis. Endothelial cells and immune cell migration.

open access: yesArthritis research, 2000
Leukocyte ingress into the synovium is a key process in the pathogenesis of rheumatoid arthritis and other inflammatory conditions. In this review, the role of endothelial cells in leukocyte extravasation will be discussed, including the role of the most relevant cellular adhesion molecules. These molecules play an important role in mediating leukocyte-

Establishment and content of sugars and phenols in Physalis callus obtained from different explants and concentrations of bap and naa - doi: 10.4025/actascibiolsci.v36i1.18074

open access: yesActa Scientiarum: Biological Sciences, 2013
Obtaining cells of Physalis pubescens is of interest for studies of primary and secondary metabolic pathways, in the search for new active molecules. Our objectives were to evaluate the regeneration potential of explants from different parts of the plant,

Axitinib induces senescence-associated cell death and necrosis in glioma cell lines: The proteasome inhibitor, bortezomib, potentiates axitinib-induced cytotoxicity in a p21(Waf/Cip1) dependent manner. [PDF]

open access: yes, 2017
Glioblastoma is associated with a poor overall survival despite new treatment advances. Antiangiogenic strategies targeting VEGF based on tyrosine kinase inhibitors (TKIs) are currently undergoing extensive research for the treatment of glioma.

The developmental cell biology of Trypanosoma brucei [PDF]

open access: yes, 2005
Trypanosoma brucei provides an excellent system for studies of many aspects of cell biology, including cell structure and morphology, organelle positioning, cell division and protein trafficking. However, the trypanosome has a complex life cycle in which

Human natural killer cell committed thymocytes and their relation to the T cell lineage. [PDF]

open access: yes, 1993
Recent studies have demonstrated that mature natural killer (NK) cells can be grown from human triple negative (TN; CD3-, CD4-, CD8-) thymocytes, suggesting that a common NK/T cell precursor exists within the thymus that can give rise to both NK cells ...

Bioreactor With Electrically Deformable Curved Membranes for Mechanical Stimulation of Cell Cultures

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Physiologically relevant in vitro models of stretchable biological tissues, such as muscle, lung, cardiac and gastro-intestinal tissues, should mimic the mechanical cues which cells are exposed to in their dynamic microenvironment in vivo. In particular,
