The current investigation was undertaken to take a review of the performed studies regarding the concentration and prevalence of aflatoxin M1 (AFM1 ) of the consumed cow milk in the Middle East. In this context, all available studies published in databases include Science Direct, PubMed, Scopus, and Web of Science among 1995 to December 2017; were screened accordingly. Also, the carcinogenic risk was estimated by calculating hazard index (HI) using the Monte Carlo simulation (MCS). The result of conducted meta-analysis for 49 articles containing 7484 data indicated that the rank order of type of milk based on the concentration of aflatoxin M1 was Ultra-high temperature processing (UHT) milk (82...

BACKGROUND: Patients with chronic kidney disease (CKD) are exposed to both traditional 'Framingham' and uremia related cardiovascular risk factors that drive atherosclerotic and arteriosclerotic disease, but these cannot be differentiated using conventional ultrasound. We used ultra-high-frequency ultrasound (UHFUS) to differentiate medial thickness (MT) from intimal thickness (IT) in CKD patients, identify their determinants and monitor their progression. METHODS: Fifty-four children and adolescents with CKD and 12 healthy controls underwent UHFUS measurements using 55-70MHz transducers in common carotid and dorsal pedal arteries...

In this study, we developed a new immunosensor that can achieve an ultra-low detection limit and high sensitivity. This new device has an electrokinetic trapping (EKT)-based nanofluidic preconcentrator, which was integrated with oscillating bubble valves, to trap concentrated antigen and immunobeads. During the immunoassay process, oscillating bubbles rapidly grew and acted as control valves and to block the microchannel. Thereafter, the trapped preconcentrated antigen plug and antibody-coated nanobeads were preserved in the region between these two valves...

The onset of psychosis is typically preceded by a prodromal phase that is characterised by the emergence of "attenuated" psychotic symptoms. This phase is described as ultra-high risk (UHR) or at-risk mental state (ARMS) of psychosis. Criteria have been established for identifying these young people who are at clinical high risk. People at ultra-high risk (UHR) of psychosis have about 30% chance of developing the illness within two years. This category was introduced with the goal of developing treatments for prevention of psychotic disorders...

Little is known about valid predictive markers for functional outcomes in an at-risk for psychosis population. In a cohort of 185 individuals (age: 13-35 years) at high risk (HR) and ultra-high risk (UHR), we assessed pan-NRG1 mRNA levels across good functional status (GFS) and poor functional status (PFS) at baseline, and good functional outcome (GFO) and poor functional outcome (PFO) at 12-month follow-up. NRG1 mRNA levels were significantly higher in individuals with PFO than individuals with GFO at 12-month follow-up...

Identifying young people at risk of developing serious mental illness and identifying predictors of onset of illness has been a focus of psychiatric prediction research, particularly in the field of psychosis. Work in this area has facilitated the adoption of the clinical staging model of early clinical phenotypes, ranging from at-risk mental states to chronic and severe mental illness. It has been a topic of debate if these staging models should be conceptualised as disorder-specific or transdiagnostic. In order to inform this debate and facilitate cross-diagnostic discourse, the present scoping review provides a broad overview of the body of literature of (a) longitudinal at-risk approaches and (b) identified antecedents of (homotypic) illness progression across three major mental disorders [psychosis, bipolar disorder (BD) and depression], and places these in the context of clinical staging...

A high rate of patients with schizophrenia (SZ) does not sufficiently respond to antipsychotic medication, which is associated with relapses and poor outcomes. Chronic peripheral inflammation has been repeatedly associated with schizophrenia risk and particularly to poor responders to treatment as usual with cognitive impairment in SZ subjects. The objective of present study was to confirm if ultra resistance to treatment in schizophrenia (UTRS) was associated to chronic peripheral inflammation in a non-selected sample of community-dwelling outpatients with schizophrenia...

Trait-like anomalies of subjective experience (aka, Basic Self-disturbance or Self-disorder, SD) have been empirically identified as schizophrenia-specific markers of vulnerability in several clinical and genetic high-risk populations. However, such specificity is still to be tested in developmental years, where emerging psychopathology is less crystallized and diagnostic boundaries more blurred. Thus, the current study explores the distribution of SD in adolescent help-seekers (age range 14 to 18) and tests the specificity of SD with respect to the severity of their diagnostic staging (Early Onset schizophrenia-spectrum psychosis [EOP], ultra high-risk [UHR] and clinical help-seeking controls [CHSC])...

INTRODUCTION: The Positive and Negative Syndrome Scale (PANSS), a comprehensive psychopathology assessment scale used in the evaluation of psychopathology in schizophrenia, is also often used in the Ultra-High-Risk (UHR) population. This paper examined the dimensional structure of the PANSS in a UHR sample. METHODS: A total of 168 individuals assessed to be at UHR for psychosis on the Comprehensive Assessment of At-Risk Mental States (CAARMS) were evaluated on the PANSS, Calgary Depression Scale for Schizophrenia (CDSS), Beck Anxiety Inventory (BAI), Brief Assessment of Cognition in Schizophrenia (BACS), and Global Assessment of Functioning (GAF)...

Plant growth retardants may play an important role in regulation of yield and quality of crops, fruits, and vegetables. Such compounds have begun to be used in the cultivation of traditional Chinese medicines (TCMs), especially for root medicines. Although the potential risks to human health of these compounds has attracted increasing attention, analytical methods for detection of plant growth retardants in TCMs remain poorly investigated. In this study, an effective and reliable method for simultaneous determination of 11 plant growth retardants in Ophiopogon japonicus and soil samples was developed by ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS)...
