Bilateral infusions of N-methyl-D-aspartate (NMDA) into the lateral hypothalamus (LH) produce gastric erosions in rats. The present study attempted to determine the neural pathways that mediate this effect. In order to interrupt axonal transmission, knife cuts (KC) were made in different planes adjacent to the LH. In separate groups of rats, KC were made anterior, posterior or lateral to the LH...

PURPOSE Assess the lamellar organisation of the peripheral and central stroma of the keratoconus (KC) and normal cornea. METHODS Five normal and three KC corneas were fixed in 2.5% glutaraldehyde and processed for electron microscopy. The ultrathin sections were observed under JEOL 1400 TEM, and digital images were taken with a bottom-mounted 11-megapixel Quamisa camera, using the iTEM softwa...

The K-complex (KC) is one of the hallmarks of Non-Rapid Eye Movement (NREM) sleep. Recent observations point to a drastic decrease of spontaneous KCs in Alzheimer's disease (AD). However, no study has investigated when, in the development of AD, this phenomenon starts. The assessment of KC density in mild cognitive impairment (MCI), a clinical condition considered a possible transitional stage ...

A study of keracyanin chloride (KC) electrochemical behavior in an aqueous buffer solution using screen-printed carbon electrodes (SPCEs) and glassy (GCEs) was performed. Cyclic voltammetry (CV) square-wave (SWV) were used to analyze the response KC under studied conditions. clear redox wave observed for KC, primarily due oxidation catechol 3′,4′-dihydroxyl group its ring B, with a minor from h...

K eratoconus (KC; MIM 148300) is a non-inflammatory corneal thinning disorder. Progressive thinning and protrusion of the cornea lead to loss of visual acuity for which the only effective treatment is corneal transplantation. The estimated prevalence of KC is 1–4 per 2000 in the general population. The age of onset is often at puberty, and the disorder is progressive until the third or fourth d...

OBJECTIVE To assess the effects of total sleep deprivation on sleep spindle and K-complex (KC) density. METHODS Eight healthy male subjects (mean age=23.4 years) participated in the experiment: they slept in the laboratory for 3 nights (one adaptation, one baseline, one recovery); baseline and recovery night were separated by a period of 40 h of continuous wake. RESULTS One night of total s...

Little is known about the micronutrient status of women and children in the Democratic Republic of the Congo, which is critical for the design of effective nutrition interventions. We recruited 744 mother-child pairs from South Kivu (SK) and Kongo Central (KC). We determined hemoglobin (Hb), serum zinc, vitamin B12, folate, ferritin, soluble transferrin receptor (sTfR), retinol binding protein ...

Pulmonary bacterial infections are a leading cause of death. Since the introduction of antibiotics, multidrug-resistant Klebsiella pneumoniae became an escalating threat. Therefore, development of methods to augment antibacterial defense is warranted. Neutrophil recruitment is critical to clear bacteria, and neutrophil migration in the lung requires the production of ELR(+) CXC chemokines. Alth...

AIM To examine the occurrence of commonly known clinical signs of keratoconus (KC), i.e. Fleischer ring, prominent corneal nerves and thinning, among unaffected family members of KC patients and healthy control individuals. METHODS Data of both eyes of 117 relatives of KC patients having no manifest disease based on videokeratography indices (KC relatives), and 142 controls were used for Pear...

Purpose To test candidate genes TSC1 and TSC2 in a family affected by tuberous sclerosis complex (TSC) where proband was also diagnosed with bilateral keratoconus (KC) and to test the hypothesis that defects in the same gene may lead to a nonsyndromic KC. Methods Next-generation sequencing of TSC1 and TSC2 genes was performed in a proband affected by TSC and KC. Identified mutation was confir...
