BACKGROUND: Individual patient data (IPD) meta-analysis allows for the exploration of heterogeneity and can identify subgroups that most benefit from an intervention (or exposure), much more successfully than meta-analysis of aggregate data. One-stage or two-stage IPD meta-analysis is possible, with the former using mixed-effects regression models and the latter obtaining study-estimates through simpler regression models before aggregating using standard meta-analysis methodology. However, a comprehensive comparison of the two methods, in practice, is lacking...

Environmental contaminants have the potential to act as developmental stressors and impair development of song and the brain of songbirds, but they have been largely unstudied in this context. 2,2',4,4',5-Pentabromodiphenyl ether (BDE-99) is a brominated flame retardant congener that has demonstrated endocrine disrupting effects, and has pervaded the global environment. We assessed the effects of in ovo exposure to environmentally relevant levels of BDE-99 on the neuroanatomy of the song-control system in a model songbird species, the zebra finch (Taeniopygia guttata)...

OBJECTIVE: In utero fetal surgery to correct incomplete closure of the spinal cord lessens the extent of permanent damage but is associated with preterm premature rupture of membranes (pPROM). We determined if compounds in amniotic fluid (AF) collected at the time of surgery predicted subsequent development of pPROM. DESIGN: Prospective study. SETTING: Hospitals in Sao Paulo, Brazil. POPULATION: Twenty four consecutive pregnant women at 24-26 weeks gestation seen between February and October 2017 with a singleton pregnancy underwent in utero surgery to correct an open spinal defect in their fetus...

BACKGROUND: The widespread use of wireless devices during the last decades is raising concerns about adverse health effects of the radiofrequency electromagnetic radiation (RF-EMR) emitted from these devices. Recent research is focusing on unraveling the underlying mechanisms of RF-EMR and potential cellular targets. The "omics" high-throughput approaches are powerful tools to investigate the global effects of RF-EMR on cellular physiology. METHODS: In this work, C57BL/6 adult male mice were whole-body exposed (nE xp  = 8) for 2 hr to GSM 1800 MHz mobile phone radiation at an average electric field intensity range of 4...

AIMS/INTRODUCTION: Previous studies have shown that the organism's nutritional status changes the protein levels of insulin receptor substrate 1 (IRS-1) in a tissue-specific manner. Although the mechanisms underlying the regulation of IRS-1 in the nutrient-rich conditions associated with diabetes and insulin resistance have been well studied, those under nutrient-poor conditions remain unknown. The aim of this study was to investigate how IRS-1 protein levels change depending on the nutritional status of 3T3-L1 preadipocytes...

Axon regeneration in the central nervous system is prevented in part by a developmental decline in the intrinsic regenerative ability of maturing neurons. This loss of axon growth ability likely reflects widespread changes in gene expression, but the mechanisms that drive this shift remain unclear. Chromatin accessibility has emerged as a key regulatory mechanism in other cellular contexts, raising the possibility that chromatin structure may contribute to the age-dependent loss of regenerative potential. Here we establish an integrated bioinformatic pipeline that combines analysis of developmentally dynamic gene networks with transcription factor regulation and genome-wide maps of chromatin accessibility...

Ethylphenidate is a psychostimulant and analogue of the commonly prescribed compound, methylphenidate (Ritalin®). There are a limited number of studies describing the disposition and pharmacologic/toxicological effects of ethylphenidate in any species. The abuse potential in equine athletes along with the limited data available regarding administration in horses necessitates further study. The objectives of the current study were to describe drug concentrations, develop an analytical method that could be used to regulate its use and describe the pharmacodynamic effects of ethylphenidate in horses...

β-lactamases (BLs) are important antibiotic resistance determinants that significantly compromise the efficacy of valuable β-lactam antibacterial drugs. For that reason, combinations with β-lactamase inhibitor were developed. Avibactam is the first non-β-lactam BL inhibitor introduced in clinical practice. Ceftazidime-avibactam represents one of the few last-resort antibiotics available for the treatment of infections caused by near pandrug-resistant bacteria. TRU-1 is a chromosomally-encoded AmpC-type BL of Aeromonas enteropelogenes, related to the FOX-type BLs and constitutes a good model for class C BLs...

INTRODUCTION: Data regarding the association between depression and dietary factors in Korean adults are limited. We hypothesized that Korean men and women with depression would have poorer nutritional intakes and different dietary habits than those without depression. METHODS: This study was based on data from the Korea National Health and Nutrition Examination Survey conducted during 2012 to 2014. Overall, 10 591 subjects (4308 men, 6529 women) aged 19 to 64 years were selected and categorized according to current depression status...

Rapid and accurate identification of endangered species is a critical component of bio-surveillance and conservation management, and potentially policing illegal trades. However, this is often not possible using traditional taxonomy, especially where only small or pre-processed parts of plants are available. Reliable identification can be achieved via a comprehensive DNA barcode reference library, accompanied by precise distribution data. However, these require extensive sampling at spatial and taxonomic scales, which has rarely been achieved for cosmopolitan taxa...

The biosynthesis of thebaine is based on the regioselective, intramolecular, oxidative coupling of (R)-reticuline. For decades, chemists have sought to mimic this coupling using stoichiometric oxidants. However, all approaches suffered from low yields or the formation of undesired regioisomers. Electrochemistry would represent a sustainable alternative in this respect but all attempts to accomplish an electrochemical synthesis of thebaine have failed so far. Herein, a regioselective and diastereoselective anodic coupling of 3',4',5'-trioxygenated laudanosine derivatives is presented, which finally enabled an electrochemical access to (-)-thebaine...

BACKGROUND: Exercise-induced bronchoconstriction (EIB) is diagnosed via exercise challenge on a treadmill. However, such testing requires complex equipment and sufficient healthcare resources. The fraction of exhaled nitric oxide (FeNO) test and mannitol bronchial provocation test (BPT) may serve as a surrogate of exercise testing. METHODS: We compared the diagnostic utilities of the FeNO test and mannitol BPT in predicting EIB in asthmatic children. We retrospectively analysed data from 60 asthmatic children aged 6-16 years...

Tracheobronchomalacia has been diagnosed using radiography or bronchoscopy to confirm bronchial changes in luminal diameter during the respiratory cycle. However, studies in healthy humans suggest that some degree of bronchial collapse may be observed during the normal respiratory cycle. In this analytical study, the luminal diameter of the bronchus to each of the six pulmonary lobes and the mean percentage of expiratory collapse from end inspiratory, end expiratory, and two forced expiratory phases (10 and 15 ml/kg) were determined via computed tomography (CT) and radiography in 22 healthy Beagle dogs...
