BACKGROUND & AIM: Activated leukocyte cell adhesion molecule (ALCAM/CD166) functions analogue to the receptor of advanced glycation end products, which has been implicated in the development of diabetic nephropathy (DN). We investigated the expression of ALCAM and its ligand S100B in patients with DN. METHODS: A total of 34 non-diabetic patients, 29 patients with type 2 diabetes and normal albuminuria and 107 patients with type 2 diabetes complicated with DN were assessed for serum concentration of soluble ALCAM (sALCAM) by ELISA...

BACKGROUND: S100B is a well-established biomarker of central nervous system (CNS) development and damage in the perinatal period. Because the fetal CNS induces an overproduction of S100B measurable in the maternal bloodstream we evaluated S100B protein in healthy pregnancies in order to provide a reference curve of the protein in the second and third trimesters and to provide information on CNS development when standard monitoring procedures could be silent or unavailable. METHODS: Between July 2012 and December 2014 we conducted a prospective study in 1213 healthy pregnancies delivering healthy newborns...

PURPOSE OF REVIEW: The purpose of this review is to revise current evidence on trigemino-vascular system (TVS) neuropeptides as potential biomarkers for chronic primary headaches, mainly for chronic migraine (CM). RECENT FINDINGS: Within sensory neuropeptides, released by an activated trigeminal nerve, calcitonin gene-related peptide (CGRP) levels seem to be a good biomarker of acute migraine and somewhat sensitive and specific for CM. CGRP, however, is not increased in 20-30% of CM patients, which suggests that CGRP is not the only neuropeptide involved in migraine pain generation and maintenance...

S100B is expressed in various types of glial cells and is involved in regulating many aspects of their function. However, little is known about its role during nervous system development. In this study, we investigated the effect of inhibiting the onset of S100B synthesis in the development of the enteric nervous system, a network of neurons and glia located in the wall of the gut that is vital for control of gastrointestinal function. Intact gut explants were taken from embryonic day (E)13.5 mice, the day before the first immunohistochemical detection of S100B, and cultured in the presence of arundic acid, an inhibitor of S100B synthesis, for 48 h...

Several studies have shown that a high consumption of vegetables and fruits is consistently associated with a low risk of oxidative stress-induced diseases, which includes some degenerative diseases such as amyotrophic lateral sclerosis, Alzheimer and Parkinson. Therefore, the objective of this study is to verify the effects of conventional and organic grape juice in the modulation of the neurotrophic factor (BDNF) and astrocytic markers protein (S100B) in hippocampus and frontal cortex of Wistar rats. In this study, 24 male Wistar rats were divided into three groups...

Invasive aspergillosis (IA) is a significant cause of morbidity and mortality following allogeneic hematopoietic cell transplantation (HCT). Previous studies have reported an association between IA development and single nucleotide polymorphisms (SNPs), but many have not been replicated in a separate cohort. The presence of a positive serum galactomannan assay (SGM+) has also been associated with a worse prognosis in patients with IA, and genetic determinants in this subset of patients have not been systematically studied...

REVIEW
Song Guo
Migraine has a strong genetic component and is characterized by multiphasic events including an initial premonitory phase with premonitory symptoms (PS). Calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating peptide-38 (PACAP38) are endogenous neuropeptides that can trigger migraine attacks and have in recent years gained considerable interest in the migraine field. Yet, the exact pathophysiological mechanisms underlying CGRP- and PACAP38-induced attacks are not fully clarified. Human provocation models have shown that these peptides induce attacks in only two- thirds of migraine patients...

AJCC stage IIIB and IIIC melanoma patients are at risk for disease relapse or progression. The advent of effective systemic therapies has made curative treatment of progressive disease a possibility. As resection of oligometastatic disease can confer a survival benefit and as immunotherapy is possibly most effective in a low tumor load setting, there is a likely benefit to early detection of progression. The aim of this pilot study was to evaluate a PET/computed tomography (CT) surveillance schedule for resected stage IIIB and IIIC melanoma...

Vitiligo is a chronic skin condition characterized by progressive depigmentation of the skin. S100B is a damage-associated molecular pattern (DAMP) protein expressed in melanocytes, which has been proposed as a marker of melanocyte cytotoxicity. While the use of S100B as a biomarker in melanoma is well established, its association with vitiligo activity has not yet been investigated. Here, we show that S100B serum levels were significantly increased in patients with active non-segmental vitiligo and strongly correlated with the affected body surface area...

Pain is associated with several conditions, such as inflammation, that result from altered peripheral nerve properties. Electroacupuncture (EA) is a common Chinese clinical medical technology used for pain management. Using an inflammatory pain mouse model, we investigated the effects of EA on the regulation of neurons, microglia, and related molecules. Complete Freund's adjuvant (CFA) injections produced a significant mechanical and thermal hyperalgesia that was reversed by EA or a transient receptor potential V1 (TRPV1) gene deletion...

OBJECTIVE: This study aimed to clarify whether therapeutic hypothermia protects against cerebral edema following cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in a porcine model via regulating the angiopoietin-Tie-2 ligand-receptor system. METHODS: Male pigs were randomized into the therapeutic hypothermia group, the normothermia group or the sham control group. CA was induced in pigs by untreated ventricular fibrillation for 8min. Brain edema was determined by measuring the cerebral cortical water content at 24h after the return of spontaneous circulation (ROSC)...

OBJECTIVE: To study the value of serum S100B protein and neuron-specific enolase (NSE) levels in predicting the severity of hand, foot and mouth disease (HFMD). METHODS: Ninety children with HFMD were classified into three groups: common type, severe type, and critical type (n=30 each). Thirty healthy children were randomly selected as the control group. ELISA was used to measure serum levels of S100B protein and NSE before and at 7 days after treatment. The receiver operating characteristic (ROC) curve was used to evaluate the prediction efficiency of S100B protein and NSE for the severity of HFMD...

S100 calcium-binding protein B (S100B), a multifunctional macromolecule mainly expressed in nerve tissues and adipocytes, has been suggested to contribute to the pathogenesis of obesity. To clarify the role of S100B in insulin action and glucose metabolism in peripheral tissues, we investigated the effect of S100B on glycolysis in myoblast and myotube cells. Rat myoblast L6 cells were treated with recombinant mouse S100B to examine glucose consumption, lactate production, glycogen accumulation, glycolytic metabolites and enzyme activity, insulin signaling, and poly(ADP-ribosyl)ation of glyceraldehyde-3-phosphate dehydrogenase (GAPDH)...

OBJECTIVES: Surviving long lasting cardiac arrest following accidental hypothermia has been reported after treatment with extra corporeal life support (ECLS), but there is a risk of neurologic injury. Most surviving hypothermia patients have a prolonged stay in the intensive care unit, where most patients experience polyneuropathy. Theoretically, accidental hypothermic cardiac arrest may in itself contribute to polyneuropathy. This study was designed to examine the impact of three hours of cardiac arrest at a core temperature of 20°C followed by reanimation of peripheral nerve function...

Impaired corneal healing is still a major cause of blindness. As RAGE (receptor for advanced glycation endproducts) is involved in inflammation and wound healing in other tissues, we here investigated its relevance for corneal wound healing. Corneal re-epithelialization after alkaline injury was analysed in an ex-vivo approach with cultured, enucleated eyes from mice either of the C57Bl/6 NChR genotype (RAGE+/+) and mice of the same strain lacking the RAGE gene (RAGE-/-). The wound area was determined time dependently by fluorescence imaging using fluorescein staining...
