PURPOSE: Vascular inflammation and leakage in sepsis is mediated by Angiopoietin-1 (Ang-1) and -2 (Ang-2) and their phosphorylation of the endothelial Tie-2 receptor. Levels of Ang-2 change in adults and children during sepsis, which is associated with severity of sepsis. This study investigates levels of Ang-1 and Ang-2 in newborns to gain insight in the vascular pathophysiology of early onset sepsis (EOS) within 72 hours after birth. METHODS: A prospective cohort study was performed amongst 71 Surinamese newborns treated with antibiotics for suspected EOS and 20 control newborns...

Ocotea species present economic importance and biological activities attributed to their essential oils (EOs) and extracts. For this reason, various strategies have been developed for their conservation. The chemical compositions of the essential oils and matK DNA sequences of O. caudata, O. cujumary, and O. caniculata were subjected to comparison with data from O. floribunda, O. veraguensis, and O. whitei, previously reported. The multivariate analysis of chemical composition classified the EOs into two main clusters...

Plant essential oils (EOs) and a wide range of their individual components are involved in a variety of biological interactions with insect pests including stimulatory, deterrent, toxic and even hormetic effects. Both the beneficial and toxic properties of citrus EOs on the Mediterranean fruit fly (medfly) have been experimentally evidenced over the last years. However, no information is available regarding the toxic or beneficial effects of the major components of citrus EOs via contact with the adults of the Mediterranean fruit fly...

OBJECTIVES: Sequelae of eosinophilic esophagitis (EoE) include food impaction and esophageal stricture. Duration of inflammation is a predicted risk factor; however, complications remain unpredictable. Studies using the functional lumen imaging probe (FLIP) have demonstrated decreased distensibility of the esophagus in adult patients with EoE. As the impact of inflammation on the developing esophagus is unknown, we investigated esophageal distensibility in a pediatric cohort to determine the effect of age, ongoing inflammation, and fibrotic features on distensibility...

We perform first-principles path integral Monte Carlo (PIMC) and density functional theory molecular dynamics (DFT-MD) calculations to explore warm dense matter states of LiF. Our simulations cover a wide density-temperature range of 2.08-15.70gcm^{-3} and 10^{4}-10^{9} K. Since PIMC and DFT-MD accurately treat effects of atomic shell structure, we find a pronounced compression maximum and a shoulder on the principal Hugoniot curve attributed to K-shell and L-shell ionization. The results provide a benchmark for widely used EOS tables, such as SESAME, LEOS, and models...

Using density-functional theory-based molecular-dynamics simulations, we have investigated the equation of state for silicon in a wide range of plasma density and temperature conditions of ρ=0.001-500g/cm^{3} and T=2000-10^{8}K. With these calculations, we have established a first-principles equation-of-state (FPEOS) table of silicon for high-energy-density (HED) plasma simulations. When compared with the widely used SESAME-EOS model (Table 3810), we find that the FPEOS-predicted Hugoniot is ∼20% softer; for off-Hugoniot plasma conditions, the pressure and internal energy in FPEOS are lower than those of SESAME EOS for temperatures above T ≈ 1-10 eV (depending on density), while the former becomes higher in the low-T regime...

V Shobi Anandi, Bhattacharyya Shaila
BACKGROUND: Measurement of 17-hydroxyprogesterone (17-OHP) in dried blood spots has been widely used as a newborn screening tool for congenital adrenal hyperplasia (CAH). Various maternal and neonatal factors can result in falsely high values of 17-OHP. There is a paucity of Indian studies in this regard because routine evaluation of newborn 17-OHP levels as a screening program is not widely practiced in India. Hence, this study was undertaken to evaluate the influence of various maternal and neonatal factors on newborn 17-OHP levels...

Essential oils (EOs) are plant-derived aroma compounds with a wide range of biological activity, but their actions are slow, and they are typically unstable to light or heat, difficult to extract and so on. To find highly potential fungicides derived from natural EOs, a series of essential oil-based β-methoxyacrylate derivatives have been designed and synthesized. The target compounds have been screened for their potential fungicidal activity against eleven species of plant pathogen fungi, including Alternaria alternata, Phomopsis adianticola, Pestalotiopsis theae, Sclerotinia sclerotiorum, etc...

Four essential oils (EOs) from Salvia officinalis L. cultivated in Spain (Murcia province) were analyzed by gas chromatography coupled with mass spectrometry (GC/MS) to determine their relative and absolute composition. The main components were α-thujone (22.8-41.7%), camphor (10.7-19.8%), 1,8-cineole (4.7-15.6%) and β-thujone (6.1-15.6%). Enantioselective gas chromatography identified (-)-α-thujone and (+)-camphor as the main enantiomers in all the analyzed EOs. Furthermore, when the EOs were tested to determine their antioxidant activity against free radicals and as ferric reducing and ferrous chelating agents, all were seen to have moderate activity due to the compounds they contained, such as linalool or terpinene...

The essential oils (EOs) of the aerial parts of Lippia origanoides (LiOr), collected in different localities of the Amazon region, were obtained by hydrodistillation and analyzed by GC and CG-MS. Principle component analysis (PCA) based on chemical composition grouped the oils in four chemotypes rich in mono- and sesquiterpenoids. Group I was characterized by 1,8-cineole and α-terpineol (LiOr-1 and LiOr-4) and group II by thymol (LiOr-2). The oil LiOr-3 showed β-caryophyllene, α-phellandrene and β-phellandrene as predominant and LiOr-5 was rich in (E)-nerolidol and β-caryophyllene...

3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) is being investigated in MDMA-assisted psychotherapy. The present study characterized the safety pharmacology of single-dose administrations of MDMA (75 or 125 mg) using data from nine double-blind, placebo-controlled, crossover studies performed in the same laboratory in a total of 166 healthy subjects. The duration of the subjective effects was 4.2 ± 1.3 h (range: 1.4-8.2 h). The 125 mg dose of MDMA produced greater 'good drug effect' ratings than 75 mg. MDMA produced moderate and transient 'bad drug effect' ratings, which were greater in women than in men...
