Age-dependent structural changes in brainstem reticular formation were studied. The significant decrease of mean number of neurons in reticular formation was revealed with age increase. The loss of neurons at maximal level was revealed in patients aged 70 years or over. The loss of neurons may result in constant significant damage to functions of reticular formation and may underlie the dysregu...

We present a case of reticular pattern dystrophy of the retinal pigment epithelium (RPE) in a 64-year-old woman. Fundus examination revealed discoloration at the macula in both eyes. Fundus autofluorescence (FAF) imaging showed clearly defined reticular hyperfluorescent lesions. Optical coherence tomography (OCT) demonstrated focal thickening of the RPE, called bumps, and the inner segment/oute...

Acetylcholine (ACh) regulates arousal and the present study was designed to provide insight into the neurochemical mechanisms modulating ACh release in the pontine reticular formation. Nitric oxide-releasing beads microinjected into the pontine reticular formation of C57BL/6J (B6) mouse caused a significant (p<0.0001) increase in ACh release. Microdialysis delivery of the nitric oxide donor NOC...

ACh regulates arousal, and the present study was designed to provide insight into the neurochemical mechanisms modulating ACh release in the pontine reticular formation. Nitric oxide (NO)-releasing beads microinjected into the pontine reticular formation of C57BL/6J (B6) mice significantly (P < 0.0001) increased ACh release. Microdialysis delivery of the NO donor N-ethyl-2-(1-ethyl-2-hydroxy-2-...

Background The present study aimed at discussing the role of ultrasonography for differential diagnosis of some reticular affections in 18 buffaloes suffered from traumatic reticuloperitonitis, diaphragmatic hernia and perireticular abscess. Material and Methods A 3.5 MHz convex transducer was used for examination of the reticular area from left and right side. B and M mode display were used fo...

Transmission electron microscope observation of mouse lymph nodes demonstrated that reticular fibers in the paracortex were invested not only by reticular cells, but occasionally also by migratory cells such as interdigitating cells, macrophages, and lymphocytes. Quantitative analysis of electron micrographs covering wide areas revealed that about 90% of the surface area of the reticular fiber ...
