To define better the subcellular mechanism of heat shock (HS)-induced cardioprotection, we examined the effect of HS, as well as selective expression of individual HS proteins (HSPs), on cell injury in neonatal rat ventricular myocytes (NRVM). HS was induced in NRVM by a rapid elevation of temperature to 42 degrees C for 20 min followed by 20-24 h of recovery at 37 degrees C. Other NRVM were in...

Background: The present study was designed to evaluate the secondary microglial activation processes after spinal cord injury (SCI). Methods: A quantitative histological study was performed to determine ED-1 positive cells, glial cell density, and cavitation size in untreated SCI rats at days 1, 2, and 4, and weeks 1, 2, 3, and 4. Results: The results of glial cell quantification along the 4900...

background: spermatozoa cryopreservation is used for the management of infertility and some other medical conditions. the routinely applied cryopreservation technique depends on permeating cryoprotectants, whose toxic effects have raised the attention towards permeating cryoprotectants-free vitrification technique. objective: to compare between the application of slow cryopreservation and vitri...

atopic dermatitis (ad) is a heterogeneous disease with regard to clinical phenotype and natural history. we investigated t cell subtypes and cytokine responses in peripheral blood and skin lesions of ad patients with various sensitivities. immunological studies were performed in 27 subjects: 9 house dust mite (hdm)-sensitized; 6 subjects with sensitizations other than hdm; 7 non-allergic ad pat...

background: some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. therefore, human adipose-derived stem cells (hadscs) may be a suitable source for regenerative medical applications....

Deformation of the alveolar epithelial basement membrane with lung inflation has been implicated in blood-gas barrier breakdown during the development of ventilator-induced lung injury. To determine the vulnerability of alveolar epithelial cells to deformation-induced injury, we developed a cell-stretching device that subjects cells to cyclic, equibiaxial strains. Alveolar epithelial type II ce...
