BACKGROUND: Nonsevere haemophilia A (HA) patients can be treated with desmopressin. Response of factor VIII activity (FVIII:C) differs between patients and is difficult to predict. OBJECTIVES: Our aims were to describe FVIII:C response after desmopressin and its reproducibility by population pharmacokinetic (PK) modelling. PATIENTS AND METHODS: Retrospective data of 128 nonsevere HA patients (age 7-75 years) receiving an intravenous or intranasal dose of desmopressin were used...

Glucocorticoids are widely used for immunosuppression in autoimmune diseases. After the resolution of hypercortisolemia, the immune system recovers allowing for autoimmune diseases to manifest. Here we investigated the presence of autoimmune and related diseases that developed after cure of endogenous Cushing syndrome (CS) in children. We identified 129 children who were diagnosed and successfully treated for endogenous CS at the National Institutes of Health from 1997 until 2017, and who were followed for at least 6 months after treatment...

Hot-melt extrusion (HME) has gained increasing attention in the pharmaceutical industry; however, its potential in the preparation of solid self-emulsifying drug delivery systems (S-SMEDDS) is still unexplored. This study sought to prepare enteric S-SMEDDS by HME and evaluate the effects of the process and formulation variables on S-SMEDDS properties via Box-Behnken design. Liquid SMEDDS were developed, and carvedilol was used as a class II model drug. Mean size, polydispersity index (PdI) and zeta potential of the resulting microemulsions were determined...

The purpose of this study was to use statistical design of experiments to develop a stable aqueous enteric coating formulation containing stabilizing excipients, such as polyethylene glycol that can minimize hydroxypropyl methylcellulose acetate succinate aggregation and minimize spray-nozzle clogging at elevated processing temperatures. The mechanisms of stabilization (i.e. charge stabilization and molecular interactions) were studied by performing zeta potential and FTIR studies. Electrostatic stabilization by sodium lauryl sulfate and hydrogen bonding by polyethylene glycol provided dispersion stability and yielded a stable aqueous coating formulation that prevented spray-nozzle clogging...

INTRODUCTION: The incidence of periprosthetic femoral fracture is constantly increasing, with high associated morbidity and mortality. Surgical treatment is guided by the Vancouver classification, but the influence of type of treatment on morbidity and mortality has been little analyzed. The theoretic advantage of implant revision over internal fixation is that it should allow earlier weight-bearing, although the impact of this on morbidity and mortality and autonomy has not been demonstrated...

BACKGROUND: Inflammation plays a role in mood and behavior that may be relevant to identifying risk factors and treatment for depression and other stress-related illnesses. The purpose of this study was to examine whether fluctuations in inflammation following a mild immune stimulus were associated with changes in daily reported features of depression for up to a week in a healthy sample of young adults. METHODS: Forty one undergraduate students completed daily diaries of mood, feelings of social disconnection, sleep, and physical symptoms for one week before and after receiving the seasonal influenza vaccine...

Advances in cognitive and affective neuroscience come largely from within-subjects comparisons, in which the functional significance of neural activity is determined by contrasting two or more experimental conditions. Clinical and social neuroscience studies have attempted to leverage between-subject variability in such condition differences to better understand psychopathology and other individual differences. Shifting from within-to between-subjects comparisons requires that measures have adequate internal consistency to function as individual difference variables...

AIM: Furosine is one of the Maillard reaction products (MRPs) and is found in a variety of heat-processed food. Yet its toxicity is still unclear. The present study was designed to assess furosine toxicity in cell models and in CD-1 mice, respectively. METHODS: In vitro, the effects of furosine on the cell viability, cell cycle and apoptosis (Hek293, HepG2, SK-N-SH and Caco2) were detected and evaluated, sensitive cell lines and proper dosage of furosine for further animal experiment were determined, and the mechanisms of toxicity were explored...

Clinical epidemiological studies have shown that there is a link between Parkinson's disease (PD) and cancer, but how PD regulates cancer development remains unknown. In our study, the effect of metabotropic glutamate receptor 5 (mGlu5 ) on hepatoma was explored in a rotenone-induced PD model both in vitro and in vivo. We found that conditioned media derived from MN9D dopaminergic neuronal cells by rotenone-induced toxicity inhibited the growth, migration, invasion and promoted apoptosis of Hepa1-6 cells, which corresponded with decreased expression of mGlu5 ...

Selection of informative genes from high dimensional gene expression data has emerged as an important research area in genomics. Many gene selection techniques have been proposed so far are either based on relevancy or redundancy measure. Further, the performance of these techniques has been adjudged through post selection classification accuracy computed through a classifier using the selected genes. This performance metric may be statistically sound but may not be biologically relevant. A statistical approach, i...

The consumption of red meat has been linked to an increased colorectal cancer (CRC) risk. One of the major hypotheses states that heme iron (present in red meat) stimulates the formation of genotoxic N-nitroso compounds (NOCs) and lipid peroxidation products (LPOs). By means of DNA adductomics, chemically induced DNA adduct formation can be mapped in relation to e.g. dietary exposures. In this study, this state-of-the-art methodology was used to investigate alkylation and (lipid per)oxidation induced DNA adduct formation in in vitro red vs...

OBJECTIVES: Toll-like receptor (TLR) -9 could have importance in human S. aureus immunity, but population level evidence for this hypothesis is missing. METHODS: We phenotyped 603 volunteers for S. aureus nasal carriage using four consecutive swabs, genotyped TLR9 promotor variants in 106 persistent carriers and 219 non-carriers, measured TLR9-mRNA expression in whole blood after stimulation with viable S. aureus, and studied mutual associations of carriage, transcriptional activity, and single nucleotide polymorphisms while accounting for sex and hormonal contraceptive use (HCU+/- )...

Phosphatase and tensin homologue (PTEN)-induced putative kinase 1 (PINK1) gene encodes a serine/threonine kinase, which acts as a molecular sensor of mitochondrial health necessary for mitochondrial quality control. The present study was designed to examine whether PINK1 expressed in C57BL/6 murine cochlea and HEI-OC1 cells and, if so, to investigate the possible mechanisms underlying the action of PINK1 in cisplatin-induced death of sensory hair cells (HCs) and spiral ganglion neurons (SGNs) in vitro. The expression pattern of PINK1, formation of parkin particles, and autophagy were determined by immunofluorescent staining...

Hyaluronic acid (HA, also known as hyaluronan), is a non-sulfated linear glycosaminoglycan polymer consisting of repeating disaccharide units of d-glucuronic acid and N-acetyl-d-glucosamine abundantly present in the extracellular matrix. The sizes of hyaluronic acid polymers range from 5000 to 20,000,000 Da in vivo, and the functions of HA are largely dictated by its size. Due to its high biocompatibility, HA has been commonly used as soft tissue filler as well as a major component of biomaterial scaffolds in tissue engineering...

5-Methoxy-2-aminoindane (MEAI) is a novel psychoactive aminoindane derivative, exerting euphoric, alcohol-like tipsy experience and reduced desire to consume alcoholic beverages. Our previous toxicological evaluation of MEAI in rats, clearly indicated MEAI's potential to be further evaluated as a promising binge mitigating agent due to its favorable safety profile. In the light of these observations, we have determined MEAI's pharmacokinetic (PK) profile in rats and evaluated in-vitro its pharmacodynamics (PD) profile...

Human cytomegalovirus (HCMV) infections cause congenital birth defects and disease in immunosuppressed individuals. Antiviral compounds can control infection yet their use is restricted due to concerns of toxicity and the emergence of drug resistant strains. We have evaluated the impact of an RNA Polymerase I (Pol I) inhibitor, CX-5461 on HCMV replication. CX-5461 inhibits Pol I-mediated ribosomal DNA transcription by binding G-quadruplex DNA structures and also activates cellular stress response pathways. The addition of CX-5461 at both early and late stages of the HCMV infection inhibited viral DNA synthesis and virus production...

The Type VI secretion system (T6SS) is a multiprotein complex used by bacteria to deliver effectors into target cells. The T6SS comprises a bacteriophage-like contractile tail structure anchored to the cell envelope by a membrane complex constituted of the TssJ outer membrane lipoprotein and the TssL and TssM inner membrane proteins. TssJ establishes contact with the periplasmic domain of TssM whereas the transmembrane segments of TssM and its cytoplasmic domain interact with TssL. TssL protrudes in the cytoplasm but is anchored by a C-terminal transmembrane helix (TMH)...

Accumulating evidence indicates an interaction between inflammation and depression since increased levels of pro-inflammatory cytokines are associated with depression-related symptoms. Melatonin is a hormone synthesized and secreted by the pineal gland with antioxidant, anti-inflammatory and antidepressant-like effects. In this way, it would be interesting to evaluate the putative antidepressant-like effect of melatonin treatment in an acute inflammation mice model of depression. The present study aimed to investigate the effect of melatonin treatment on lipopolysaccharide (LPS) induced depressive-like behavior, neuroinflammation, oxidative stress and alteration on brain-derived neurotrophic fator (BDNF) levels...

With exposure to acute normobaric hypoxia, global cerebral oxygen delivery is maintained via increases in cerebral blood flow (CBF); therefore, regional and localized changes in oxygen tension may explain neurocognitive impairment. Neurovascular coupling (NVC) is the close temporal and regional relationship of CBF to changes in neural activity and may aid in explaining the localized CBF response with cognitive activation. High-altitude related cognitive impairment is likely affected by hypocapnic cerebral vasoconstriction that may influence regional CBF regulation independent of hypoxia...
