UNLABELLED Aging is characterized by progressive loss of metabolic and biochemical functions and accumulation of metabolic by-products, including advanced glycation end products (AGEs), which are observed in several pathological conditions. A number of waste macromolecules, including AGEs are taken up from the circulation by endocytosis mainly into liver sinusoidal endothelial cells (LSECs) and...

The insect mushroom bodies (MBs) are multimodal signal processing centers and are essential for olfactory learning. Electrophysiological recordings from the MBs' principal component neurons, the Kenyon cells (KCs), showed a sparse representation of olfactory signals. It has been proposed that the intrinsic and synaptic properties of the KC circuitry combine to reduce the firing of action potent...

The effect of lipopolysaccharide (LPS) on the expression of CD95 (APO-1/Fas) receptor and ligand (CD95L) was studied in primary cultures of rat liver Kupffer cells (KCs), sinusoidal endothelial cells (SECs), and parenchymal cells (PCs) at the messenger RNA (mRNA) level and by means of immunocytochemistry. LPS treatment of KCs and SECs led to a three- to five-fold increase in CD95L mRNA levels w...

A hypertrophic scar is characterized by fibroblast proliferation and excessive extracellular matrix deposition. Emerging evidence has revealed that fetal keratinocytes (KCs) contribute to scarless wound healing. However, the association between fetal keratinocytesand hypertrophic scarring remains unclear. In the present study, human KCs of different gestational ages were isolated and co‑culture...

BACKGROUND Hypoparathyroidism in children is a heterogeneous group with diverse genetic etiologies. To aid clinicians in the investigation and management of children with hypoparathyroidism, we describe the phenotype of a 6-year-old child with hypoparathyroidism and short stature diagnosed with Kenny-Caffey syndrome (KCS) Type 2 and the subsequent response to growth hormone (GH) treatment. CA...

The honeybee olfactory pathway comprises an intriguing pattern of convergence and divergence: ~60.000 olfactory sensory neurons (OSN) convey olfactory information on ~900 projection neurons (PN) in the antennal lobe (AL). To transmit this information reliably, PNs employ relatively high spiking frequencies with complex patterns. PNs project via a dual olfactory pathway to the mushroom bodies (M...

Kenny-Caffey syndrome (KCS) is characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular bones, delayed closure of anterior fontanelle, eye abnormalities, and hypoparathyroidism. The autosomal dominant form (KCS Type 2) caused by mutations in FAM111A is distinguished from the autosomal recessive form (KCS Type1), caused by mutations in TBCE gene, by the...

PURPOSE To establish a rabbit model for keratoconjunctivitis sicca (KCS) to study autologous submandibular gland transfer for treating severe KCS. METHODS In 2 groups of 10 rabbits, left eyes were operated and right eyes were controls. In the trichloroacetic acid-treated group, the lacrimal and harderian glands and nictitating membrane were removed surgically; the palpebral and bulbar conjunc...

Dry eye syndrome, or keratoconjunctivitis sicca (KCS), affects tens of millions of people worldwide, representing one of the most common ocular diseases. The National Eye Institute Industry Workshop on Clinical Trials in Dry Eyes produced a classification that essentially separates dry eye syndrome into two major types: tear-deficient forms (including Sjögren’s syndrome and non-Sjögren’s tear-d...
