BACKGROUND: The placenta is a most interesting but unfortunately often ignored and misunderstood organ. Placental abnormalities, therefore, can be an "early warning system" for fetal problems. A complete prenatal sonographic examination of the placenta is an essential component as its abnormalities can have a direct effect on fetal or maternal outcomes, obstetrical management and future fertility. OBJECTIVE: To determine whether any association exists between the finding of an increased thickness of placenta, abnormal placenta shape, placental calcification, placental lake and abnormal cord insertion site at 20-22 and 30-32 weeks gestation with an increased risk of uteroplacental complications or a poor pregnancy outcome...

OBJECTIVE: We aimed to evaluate the outcomes of growth-restricted fetuses with absent end-diastolic velocity in the umbilical arteries (UA-AEDV), and investigate the relationship between Doppler flow velocity waveforms in the ductus venosus (DV) and the clinical features. MATERIALS AND METHODS: This was a retrospective study of growth-restricted fetuses diagnosed with UA-AEDV delivered at our institution between 2013 and 2015. The time from diagnosis of UA-AEDV to delivery, postnatal survival, and developmental prognoses were the primary outcomes...

OBJECTIVES: Diagnosing fetal heart failure remains challenging because it is difficult to know how well the fetal myocardium will perform as loading conditions change. In adult cardiology, natriuretic peptides (NPs) are established marker of heart failure. However, the number of studies investigating NP levels in fetuses is quite limited. The aim of this study was to evaluate the significance of plasma NP levels in the assessment of heart failure in fetuses with congenital heart defect (CHD) and arrhythmia...

The present study aimed to evaluate the impact of total extracorporeal circulation on hemodynamics and placental function in an ovine fetal model. Mid-term ovine fetuses (n=6) underwent extracorporeal circulation (30 min), cardioplegic arrest (20 min) and monitoring (120 min). The ascending aorta and umbilical cords of the fetuses were occluded during the bypass and an extracorporeal membrane oxygenator was used as the oxygen source. Biventricular intracardiac pressures, echocardiographic data, blood gas levels and placental function variables were recorded, and statistical analysis was performed using the repeated-measure analysis of variance test...

OBJECTIVE: Screening criteria for neonatal encephalopathy remain a complex combination of subjective and objective criteria. We examine the utility of universal cord blood gas testing and mandatory encephalopathy evaluation for infants with pH ≤7.10 on umbilical cord arterial blood gas (cABG) as a single screening measure for timely identification of moderate/severe encephalopathy. DESIGN, SETTING, PATIENTS: Infants born at a single centre between 2008 and 2015, who were ≥36 weeks, had no congenital anomalies and had a cABG pH ≤7...

WHAT IS KNOWN AND OBJECTIVE: Phenobarbital is the first-line treatment of seizures in asphyxiated neonates; however, due to the high pharmacokinetic variability in this population, there is no consensus on the optimal dosage regimen. This study was conducted to identify variables that affect phenobarbital fate during routine clinical care and then to evaluate the dosage schedule that could be applied in term asphyxiated neonates with respect to achieving the target therapeutic range. METHODS: Phenobarbital pharmacokinetics was calculated based on serum concentrations measurements using one-compartmental model...

Interscalene regional anesthesia is an established and highly effective procedure; however, it represents an increased level of risk due to the close proximity of anatomical structures, such as the cervical spinal cord and many vessels. Furthermore, due to inadvertent placement of a catheter close to the cervical spinal cord or into a vessel, as opposed to a single shot injection technique, it remains a latent danger until it is removed. This article describes seven  cases of misplaced catheters. The etiology and symptoms are discussed as well as recommendations regarding the prevention of catastrophic complications...

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease affecting the upper and lower motor neurons in the motor cortex and spinal cord. Abnormal accumulation of mutant superoxide dismutase I (SOD1) in motor neurons is a pathological hallmark of some forms of the disease. We have shown that the orderly progression of the disease may be explained by misfolded SOD1 cell-to-cell propagation, which is reliant upon its active endogenous synthesis. Reducing the levels of SOD1 is therefore a promising therapeutic approach...

BACKGROUND: The Na(+)/K(+)-ATPases are transmembrane ion pumps important for maintenance of ion gradients across the plasma membrane that serve to support multiple cellular functions, such as membrane potentials, regulation of cellular volume and pH, and co-transport of signaling transmitters in all animal cells. The α2Na(+)/K(+)-ATPase subunit isoform is predominantly expressed in astrocytes, which us the sharp Na(+)-gradient maintained by the sodium pump necessary for astroglial metabolism...

Clostridial neurotoxins, botulinum neurotoxins (BoNT) and tetanus neurotoxin (TeNT), are potent toxins, which are responsible for severe neurological diseases in man and animals. BoNTs induce a flaccid paralysis (botulism) by inhibiting acetylcholine release at the neuromuscular junctions, whereas TeNT causes a spastic paralysis (tetanus) by blocking the neurotransmitter release (glycine, GABA) in inhibitory interneurons within the central nervous system. Clostridial neurotoxins recognize specific receptor(s) on the target neuronal cells and enter via a receptor-mediated endocytosis...

Albumin-conjugated multilayered nanoemulsion (albumin-MNE) of methyl prednisolone (MP) was developed to ensure the specificity of the drug at the spinal cord injury (SCI) site. MNE was prepared by emulsification followed by ionic deposition of oppositely charged polymer followed by albumin conjugation using N-hydroxysuccinimide. Prepared nanoemulsion was characterized for particle size, polydispersity index (PDI), zeta potential (Zp), pH, viscosity, and entrapment efficiency. It was further evaluated for shape and morphological analysis, in vitro release, cell viability, and in vivo efficacy against post SCI-like conditions in terms of behavioral assessment, histopathological evaluation, and immunoflorescence assay of the histological sections showing Bax-driven apoptosis...

BACKGROUND: Preterm breech delivery is associated with a higher perinatal mortality rate compared with preterm vertex delivery, and some studies suggest caesarean section leads to lower mortality rates. Few studies include infants delivered less than 26 weeks gestation, and where included, results are often not stratified by gestational age. There is also a lack of consistent reporting on neonatal and maternal morbidity outcome measures. AIMS: To determine if mode of delivery for singleton extreme preterm breech fetuses is associated with a difference in perinatal mortality, neonatal and maternal morbidity...

The cerebrospinal fluid (CSF) is circulating around the entire central nervous system (CNS). The main function of the CSF has been thought to insure the global homeostasis of the CNS. Recent evidence indicates that the CSF also dynamically conveys signals modulating the development and the activity of the nervous system. The later observation implies that cues from the CSF could act on neurons in the brain and the spinal cord via bordering receptor cells. Candidate neurons to enable such modulation are the cerebrospinal fluid-contacting neurons (CSF-cNs) that are located precisely at the interface between the CSF and neuronal circuits...

A self-assembled nine-element optoelectronic tongue consisting of a positively charged water-soluble poly(para-phenyleneethynylene) and three metal ions (Fe(2+) , Co(2+) , and Cu(2+) ) at three different pH values (7, 10, and 13) discriminates all of the 20 natural amino acids in water. Unknown identification was not ideal. Addition of a highly positively charged green fluorescent protein in the presence of Fe(2+) , Co(2+) , and Cu(2+) increased the unknown identification to above 86 %. Linear discriminant analysis (LDA) orders the responses according to the amino acid type, that is, hydrophobic, polar, anionic, or cationic...
