Oral plus vaginal alpha-lipoic acid in women at risk for preterm delivery

Objective: The etiology of preterm labor is multifactorial. An inflammatory response is always involved with the activation of NF-kB that determines synthesis and release of inflammatory molecules, implicated in fetal membrane activation, cervical modifications, abdominal pain and spontaneous uterine contractions. There is a close relationship between preterm birth and cervical shortening in the second quarter of pregnancy. We evaluated the benefits of alpha-lipoic acid administration on women considered at risk of preterm delivery due to the presence of symptoms (pelvic pain and uterine contractions) or reduced cervical length. Patients and Methods: This prospective observational study was carried out at the Gynecology and Obstetrics Unit of Palermo University Hospital (Palermo, Italy), from October 2015 to April 2016. The inclusion criteria were: women aged 18-35, with gestational age between 24 and 33 weeks of amenorrhea, pregnancy at risk of preterm delivery due to cervical length between 35-25 mm (in presence of symptoms) or < 30 and > 15 mm (if asymptomatic), intact membranes and negative for vaginosis. Patients were treated daily with alpha lipoic acid orally (300 mg, twice a day for 30 days) and vaginally (10 mg, once a day for 10 days), or untreated (controls). Patients were evaluated at the baseline (T 0), after 7 days, after 30 days, and at 34 weeks of gestation considering: maternal characteristics, symptomology and cervical length. Results: Among 60 analyzed women, 50 were treated orally and vaginally with alpha-lipoic acid, whereas 10 did not undergo any therapy. In the treated group, 10 patients were asymptomatic and 40 symptomatic. The symptoms disappeared in 37 patients. In the untreated group, 4 women were symptomatic and 6 asymptomatic. At the end all women were symptomatic. Mean cervical length showed a reduction in the untreated group compared to the treated group. Conclusions: The vaginal/oral-combined administration with alpha-lipoic acid showed effectiveness in reducing symptoms and preventing cervical shortening in our set of patients. No adverse effects were detected during the treatment

The performance of the EU-Rotate_N model in predicting the growth and nitrogen uptake of rotations of field vegetable crops in a Mediterranean environment

The EU-Rotate_N model was developed as a tool to estimate the growth and nitrogen (N) uptake of vegetable crop rotations across a wide range of European climatic conditions and to assess the economic and environmental consequences of alternative management strategies. The model has been evaluated under field conditions in Germany and Norway and under greenhouse conditions in China. The present work evaluated the model using Italian data to evaluate its performance in a warm and dry environment. Data were collected from four 2-year field rotations, which included lettuce (Lactuca sativa L.), fennel (Foeniculum vulgare Mill.), spinach (Spinacia oleracea L.), broccoli (Brassica oleracea L. var. italica Plenck) and white cabbage (B. oleracea convar. capitata var. alba L.); each rotation used three different rates of N fertilizer (average recommended N1, assumed farmer's practice N2=N1+0·3×N1 and a zero control N0). Although the model was not calibrated prior to running the simulations, results for above-ground dry matter biomass, crop residue biomass, crop N concentration and crop N uptake were promising. However, soil mineral N predictions to 0·6 m depth were poor. The main problem with the prediction of the test variables was the poor ability to capture N mineralization in some autumn periods and an inappropriate parameterization of fennel. In conclusion, the model performed well, giving results comparable with other bio-physical process simulation models, but for more complex crop rotations. The model has the potential for application in Mediterranean environments for field vegetable production

Impact of combination chemotherapy on toxicity in ovarian cancer: Systematic revision of literature and meta-analysis

The purpose of this statistical analysis is to demonstrate the real advantages in terms of cost-benefit of combination chemotherapy compared with single-agent chemotherapy. The trials, which are used in this meta-analysis, have been searched on PubMed database and they are phase II or randomized phase III studies with only chemotherapy regimens. In this meta-analysis were evaluated adverse effects with odds ratio (OR), which is expressed in 95% confidence intervals (95% CI). Only 4 studies contained all the set selection criteria and they were selected. The data, which were obtained, were analyzed using MedCalc Application. The combination therapy was more strongly linked to certain adverse events than to chemotherapy with a single agent: thrombocytopenia, anemia, neutropenia and nausea. The data obtained for leukopenia, for vomiting and for stomatitis are not statistically significant, as well as those of antitumor activity. Obtained data allow us to state that the overall combination therapy is more closely related to adverse effects such as thrombocytopenia, anemia, neutropenia and nausea compared tosingle-agent chemotherapy

The Relationship Between Maternal and Obese Children’s Daily Physical Activity.

International Journal of Exercise Science 12(5): 1302-1314, 2019. This study examined the effects of maternal influence on child’s daily physical activity. Participants consisted of eight families; parents (n = 9) and obese children (n = 10). Families were asked to attend exercise sessions at a university laboratory for 10 weeks. Daily physical activity was measured with a MovBand 3 which is a wrist worn accelerometer that records physical activity as moves. Linear mixed-effects models were used to predict daily physical activity over time and child physical activity as a function of parent physical activity on a day-to-day basis. Physical activity for all participants did not change significantly (p \u3e .05) over the course of the intervention, however, there was a significant (p = .001) relationship between maternal and child physical activity showing for every step a mother took their child took 1.2 steps. On average, mothers achieved 2825.18 ± 1282.77 fewer moves than their children on a daily basis. Encouraging parents to engage in physical activity with their children may have a positive impact on their obese child’s daily physical activity involvement

Developmental exposures to perfluorooctanesulfonic acid (PFOS) impact embryonic nutrition, pancreatic morphology, and adiposity in the zebrafish, \u3cem\u3eDanio rerio\u3c/em\u3e

Perfluorooctanesulfonic acid (PFOS) is a persistent environmental contaminant previously found in consumer surfactants and industrial fire-fighting foams. PFOS has been widely implicated in metabolic dysfunction across the lifespan, including diabetes and obesity. However, the contributions of the embryonic environment to metabolic disease remain uncharacterized. This study seeks to identify perturbations in embryonic metabolism, pancreas development, and adiposity due to developmental and subchronic PFOS exposures and their persistence into later larval and juvenile periods. Zebrafish embryos were exposed to 16 or 32 μM PFOS developmentally (1–5 days post fertilization; dpf) or subchronically (1–15 dpf). Embryonic fatty acid and macronutrient concentrations and expression of peroxisome proliferator-activated receptor (PPAR) isoforms were quantified in embryos. Pancreatic islet morphometry was assessed at 15 and 30 dpf, and adiposity and fish behavior were assessed at 15 dpf. Concentrations of lauric (C12:0) and myristic (C14:0) saturated fatty acids were increased by PFOS at 4 dpf, and PPAR gene expression was reduced. Incidence of aberrant islet morphologies, principal islet areas, and adiposity were increased in 15 dpf larvae and 30 dpf juvenile fish. Together, these data suggest that the embryonic period is a susceptible window of metabolic programming in response to PFOS exposures, and that these early exposures alone can have persisting effects later in the lifecourse

3D printed catalytic reactors for aerobic selective oxidation of benzyl alcohol into benzaldehyde in continuous multiphase flow

In this work, novel, patterned monolithic reactors were devised to explore more efficient routes for reactant conversion in order to investigate their potential to replace the packed bed and batch reactors conventionally employed in chemical industries. Well-defined bimetallic formulations were developed to substitute platinum group metals and critical raw materials such as palladium and cobalt, at least in part, by less active, but more sustainable and cost-effective metals such as earth-abundant iron. FePd and FeCo based monoliths were 3D printed and stacked in a continuous flow tubular reactor for testing the selective oxidation of benzyl alcohol (BA) into benzaldehyde (BZ) under mild conditions (80–100 °C and atmospheric pressure). The novel monolithic reactors were evaluated against current state-of-the-art reactor technologies, conventional packed bed and batch reactors. The FeCo- and FePd-Al2O3-supported monolithic catalyst beds showed higher conversion and TOF than their packed bed counterparts under the same operating conditions, revealing the impact of the novel design on both regular geometry and composition. What is of particular interest in the catalytic measurements shown is that the combined stacking of two monoliths in a flow reactor, Al2O3-supported Fe and GO-supported FePd catalysts, can significantly improve the performance with an increase in TOF of up to 90% in comparison to their FePd analogues. Mathematical modelling was used to obtain additional insights into the physical and chemical processes governing the rate of BA conversion. It was found that due to the flow regime inside the microchannels, an axial dispersion model was appropriate, which allowed for mapping the concentration profiles of the reactants and products within the respective monolith geometries
