The aim of this study was to evaluate the impact of in situ cross-linkers on the gelling and mucoadhesive properties of thiomers. Polycarbophil-cysteine conjugate (PCP-cys) was synthesized by covalent attachment of l-cysteine to polycarbophil via amide bond formation mediated by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDAC) and N-hydroxysuccinimide (NHS) whereas in situ cross-linkers (PAA-cys-MNA) were synthesized by the same bond formation between poly(acrylic acid) (PAA) of 2.1-, 6-, and 15kDa and 2-((2-amino-2-carboxyethyl)disulfanyl)nicotinic acid (cys-MNA) used as ligand...

Phencyclidine (PCP) is a potent drug of abuse that induces sustained schizophrenia-like symptoms in humans by blocking neurotransmission at N-methyl-D-aspartate (NMDA)-type glutamate receptors. Alterations in NMDA receptor function have been linked to numerous behavioral deficits and cognitive dysfunction. Classical eye-blink conditioning (EBC), including delay (dEBC) and trace (tEBC) pafadigms, provides an effective means to study the neurobiology of associative motor learning in rodents, mammals and primates...

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease, and its control rate has remained low worldwide. Studies have found that telemonitoring blood pressure (BP) helped control hypertension in randomized controlled trials. However, little is known about its effect in a structured primary care model in which primary care physicians (PCPs) are partnering with cardiology specialists in electronic healthcare data sharing and medical interventions. This study aims to identify the effects of a coordinated PCP-cardiologist model that applies telemedicine tools to facilitate community hypertension control in China...

Many in vitro or in vivo studies highlighted the potential deleterious effects of phenolic organohalogenated compounds (POHs) on the health, particularly on the thyroid system homeostasis, however few large scale human epidemiological studies have been carried out, especially in Europe. Further studies monitoring the human contamination by POHs, the sources of exposure and the influence of these compounds on thyroid health are still needed. Therefore we determined the concentrations of 16 POHs (pentachlorophenol (PCP), tetrabromobisphenol A (TBBPA), 4 bromophenols (BPs), 3 hydroxy-polybromodiphenylethers (OH-PBDEs) and 7 hydroxy-polychlorobiphenyls (OH-PCBs)) in serum from 274 people aged from 18 to 76years old living in Liege (Belgium) and the surrounding area...

Symptoms of schizophrenia have been linked to insults during neurodevelopment such as NMDA receptor antagonist exposure. In animal models, this leads to schizophrenia-like behavioral symptoms as well as molecular and functional changes within hippocampal and prefrontal regions. The aim of this study was to determine how administration with the NMDA receptor antagonist, phencyclidine (PCP), during neurodevelopment affects functional network changes within the hippocampus and medial prefrontal cortex (mPFC). We recorded field potentials in vivo following electrical brainstem stimulation and observed a suppression of evoked theta power in ventral hippocampus, while evoked gamma power in mPFC was enhanced in rats administered neonatally with PCP...

BACKGROUND: The current literature speculates ideal postdischarge follow-up focusing on transitions from hospital to home can range anywhere between 48 hours and 2 weeks. However, there is a lack of evidence regarding the optimal timing of follow-up visit to prevent readmissions. OBJECTIVE: The purpose of this study is to evaluate the impact of early (<48 hours) versus late (48 hours-14 days) postdischarge medication reconciliation on readmissions and emergency department (ED) use...

Conditions that cause cognitive impairment and behavioural and personality changes, such as Alzheimer's disease (AD) and related dementia, have global impact across cultures. However, the experience of dementia care can vary between individuals, families, formal caregivers, and social groups from various cultures. Self-reported measures, caregiving stress models, and conceptual theories have been developed to address the physical, financial, psychological, and social factors associated with the experience of dementia care...

Mammalian limb development is driven by the integrative input from several signaling pathways; a failure to receive or a misinterpretation of these signals results in skeletal defects. The brachydactylies, a group of overlapping inherited human hand malformation syndromes, are mainly caused by mutations in BMP signaling pathway components. Two closely related forms, Brachydactyly type B2 (BDB2) and BDB1 are caused by mutations in the BMP antagonist Noggin (NOG) and the atypical receptor tyrosine kinase ROR2 that acts as a receptor in the non-canonical Wnt pathway...

New psychoactive substances (NPS) are commonly referred to as "research chemicals", "designer drugs" or "legal highs." One NPS class is represented by dissociative anesthetics, which include analogues of the arylcyclohexylamine phencyclidine (PCP), ketamine, and diphenidine. A recent addition to the NPS market was 4-[1-(3-methoxyphenyl)cyclohexyl]morpholine (3-MeO-PCMo), a morpholine analogue of 3-MeO-PCP. Although suspected to have dissociative effects in users, information about its pharmacological profile is not available...

Despite the importance of the RAS-RAF-MAPK pathway in normal physiology and disease of numerous organs, its role during pituitary development and tumourigenesis remains largely unknown. Here we show that the over-activation of the MAPK pathway, through conditional expression of the gain-of-function alleles BrafV600E and KrasG12D in the developing mouse pituitary, results in severe hyperplasia and abnormal morphogenesis of the gland by the end of gestation. Cell-lineage commitment and terminal differentiation are disrupted, leading to a significant reduction in numbers of most of the hormone-producing cells before birth, with the exception of corticotrophs...
