throughout the world, millions of muslims fast daily during the month of ramadan from sunrise (sahar) until sunset (iftar). considering the impacts of environment on physiological functions, we performed this study in order to examine the effects of ramadan fasting on some blood parameters of healthy volunteers and hypertensive patients. according to the results, there were no significant chang...

Retinal ganglion cell (RGC) transplantation is a promising strategy to restore visual function resulting from irreversible RGC degeneration occurring in glaucoma or inherited optic neuropathies. We previously demonstrated FGF2 induced differentiation of mouse embryonic stem cells (ESC) to RGC lineage, capable of retinal ganglion cell layer (GCL) integration upon transplantation. Here, we evalua...

Raman spectroscopy has been linked to a high-pressure optical cell for the in situ study of supercritical carbon dioxide (SC-CO2)-solute interactions. The body of the cell is made of a stainless steel cylinder enclosing a volumetric capacity of 24 mL, allowing optical access through sapphire windows on both ends. An argon ion laser was used for the excitation and Raman spectra were collected in...

purpose: to report a case of unilateral severe visual loss and bilateral optic disc cupping secondary to brain metastasis of bronchogenic carcinoma patient and findings: a 48 year-old woman presented with severe visual loss of left eye without redness or pain or any systemic findings .clinical findings included decreased visual acuity of left eye to 4 m cf and (+3) positive marcus-gunn reflex ....

There has been a tendency to discount thin-layer chromatography (TLC) in recent years because of the availability of high-performance liquid chromatography (HPLC) methods that appeared to offer greater versatility and ease of quantification, amongst other reasons. However, TLC has made a comeback, largely because of the high reproducibility and lower costs of commercial pre-coated plates. It is...

abstract meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal melanocytes. the locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. the manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that causes ...
