Ultrastructural localization of InsP3 receptor in mouse cerebellar Purkinje cells was investigated by immunogold technique using three monoclonal antibodies (mab 10A6, 4C11 and 18A10). The epitopes of the three antibodies were numerously detected on the smooth endoplasmic reticulum (ER) (especially, on the stacks of flattened smooth ER, subsurface cisterns and spine apparatus), scantily on the ...

The clinical significance of traumatic subarachnoid hemorrhage (TSAH) was studied in 20 head-injured patients. They were classified into mild (9) and severe (11) groups by their initial Glasgow Coma Scale (GCS) scores. TSAH detected by computed tomography was localized in the Sylvian fissure in four of the nine mild group patients, but was also found in other basal subarachnoid cisterns in the ...

The semi-arid region of Brazil, marked by low human development indicators, has historically suffered from water scarcity, being the focus public policies to reduce socioeconomic, water, and climatic vulnerabilities for more than a century. Among recent initiatives, Cisterns Program stands out as an attempt guarantee food security family farmers through construction social technologies storage,...

The ultrastructural effects of dark, light, and low temperature were investigated in the cone cell endings of the red-eared turtle (Pseudemys scripta elegans). Thin sections revealed that in dark-adapted retinas maintained at 22 degrees C, the neural processes which contact the cone cells at the invaginating synapses penetrated deeply into the photoreceptor endings. When dark-adapted retinas we...

A 60-year-old woman was admitted to the hospital due to a sudden loss of consciousness. Computed tomography (CT) revealed a thick subarachnoid hemorrhage in almost all of the parachiasmatic cisterns, including the sylvian cisterns, with mild hydrocephalus. Three dimensional (3D)-CT angiography showed an irregularly shaped aneurysm at the bifurcation of the left A2 and the frontopolar artery. Th...

The frontotemporosphenoidal craniotomy, usually denominated pterional craniotomy, was first described by Yasargil in 1975 and is one of the earliest landmarks of the advents of microneurosurgery1-3. This approach enables, specifically, the exposure of the entire frontoparietal operculum4,5, the opening of the entire sylvian fissure6,7 and all anterior cisterns of the encephalon base2,5, which m...

We used electron tomography of frog saccular hair cells to reconstruct presynaptic ultrastructure at synapses specialized for sustained transmitter release. Synaptic vesicles at inhibited synapses were abundant in the cytoplasm and covered the synaptic body at high density. Continuous maximal stimulation depleted 73% of the vesicles within 800 nm of the synapse, with a concomitant increase in s...

Ultrastructural techniques and electron probe microanalysis were used to determine whether or not the smooth endoplasmic reticulum (SER) within presynaptic nerve terminals is a Ca-sequestering site. The three-dimensional structure of the SER was determined from serial sections of synaptosomes. The SER consists of flattened cisterns that may branch and are frequently juxtaposed to mitochondria. ...

No extensive work has been published to date concerning the cisterns of southern Anatolia. Nor does recent research present a comprehensive approach especially association with buildings and open spaces as well their stylistic features. From this point view, paper aims fill part lacuna by examining potential role located in Late Antique-Byzantine countryside Anatolia, namely areas Lycia, Pamphy...

BACKGROUND AND PURPOSE We sought to determine the contribution of the amount, distribution, and clearance rate of extravasated blood in relation to occurrence of infarction and outcome in patients with aneurysmal subarachnoid hemorrhage. METHODS We prospectively studied 59 consecutive patients with aneurysmal subarachnoid hemorrhage admitted within 72 hours by means of serial computed tomogra...
