Ozone treatment of stored potato tubers
During storage, potato tubers are susceptible to different pathogen, which can attack
the skin and flesh of the tubers. The most serious damage can be caused by rot inducing bacteria
and fungi. A possible way to prevent microbial damage may be the use of ozone in the air
ventilated through the stored tubers. However, the tubers can undergo qualitative changes, e.g.
dehydration and loss of starch content. This article presents the results of a five-month experiment
in which ozone concentration of 5 mg m-3 was periodically introduced in some of the stored potato
tubers of the cultivar ‘Dali’. All potato tubers were stored in closed storage boxes with a metal
frame and wood panels in the floor and walls (ground area 1.6×1.2 m, height 0.95 m) which were
continuously aerated using the ambient air in a potato warehouse. There was 900 kg of tubers
stored in the box. At the end of the experiment, the ozonated variant was compared with the
control (not treated). The ozone-treated tubers had 2.95 times lower incidence of infection by
rot and the number of microorganisms on healthy tubers was lower than the control. The
ozone-treated tubers were less frequently dehydrated. The water loss was higher in control by
0.86 %. There was no significant difference in silver scurf manifestation or in the starch content
between the two variants
Real-Life Report on Chemoembolization Using DEBIRI for Liver Metastases from Colorectal Cancer
Background. Transarterial chemoembolization (TACE) has been investigated in patients with liver metastases from colorectal cancer (LMCRC). Limited experience and available data suggest that TACE can achieve disease stabilization or improvement, even in heavily pretreated patients. Methods. Patients with LMCRC, ECOG 0–2, who failed at least 1 line of systemic chemotherapy, received embolizations with 2 mL of microspheres preloaded with 100 mg of irinotecan. Beads were delivered selectively into hepatic arteries. Primary endpoint was overall survival (OS), analyzed using the Kaplan-Meier method. Secondary endpoint was safety, assessed using CTCAE version 4.0. Results. 27 patients were treated using DEBIRI. Patient median age was 57 years (range was 45–82 years). The median number of total embolizations was 1.3 (range 1–3). The median OS was 5.4 months (95% CI; 1.1–22.7 months). The most reported postembolization events were nausea (8/27), vomiting (6/27), right upper quadrant pain (16/27), fatigue (9/27), and the development of ascites (6/27). 5/26 patients required hospitalization after TACE for severe pain. Hospitalization was also required for 1 case of allergic reaction and 1 case of infection. Conclusion. Our data suggest that TACE with DEBIRI could be efficacious in a palliative setting for patients with LMCRC, but they do not necessarily support routine use in clinical practice
Longitudinal study to assess changes in arterial stiffness and cardiac output parameters among low-risk pregnant women.
AIM: A single-centre, prospective longitudinal study to assess changes in maternal arterial stiffness and cardiac output parameters among low-risk healthy pregnant women. METHODOLOGY: Thirty low-risk, healthy, pregnant women attending their routine antenatal dating ultrasound scan were recruited. Non-invasive assessment of arterial stiffness and cardiac output was undertaken at five gestational windows from 11 to 40 weeks of pregnancy. Data were analysed using a linear mixed model incorporating time and other relevant predictors as fixed effects, and patient as a random effect. RESULTS: Gestational age had a significant effect on all arterial stiffness parameters, including brachial augmentation index (AIx) (p = .001), aortic AIx (p = .002) and aortic pulse wave velocity (p = .002). The aortic AIx (%) reduced during pregnancy: the lowest mean (standard error, SE) was 4.07 (1.01) at 28 weeks before it increased to 7.04 (SE 1.64) at 40 weeks. Similarly, non-invasive assessments of cardiac output (p < .001), stroke volume (p = .014), heart rate (p < .001) and total peripheral resistance (p < .001) demonstrated significant changes with gestational age. Mean cardiac output (l/m) increased during pregnancy reaching a peak at 28 weeks gestation 6.66 (SE 0.28), but dropped thereafter to reach 5.71 (SE 0.25) around term. CONCLUSION: The current study provides pregnancy normograms for gestational changes in arterial stiffness and cardiac output parameters among low-risk, healthy pregnant women. Further work will be required to assess the risk of placental mediated diseases and pregnancy outcome among pregnant women with parameters outside the normal range
Assessment of arterial function in pregnancy: recommendations of the International Working Group on Maternal Haemodynamics.
There is strong evidence supporting a role of maternal arterial dysfunction in pregnancy-specific disorders such as pre-eclampsia and intra-uterine growth restriction. As more work is focused towards this field, it is important that methods and interpretation of arterial function assessment are utilised appropriately. Here, we summarise techniques and devices commonly used in maternal health studies, with considerations of technical application within pregnant cohorts

Syncytiotrophoblast derived extracellular vesicles transfer functional placental miRNAs to primary human endothelial cells
During the pregnancy associated syndrome preeclampsia (PE), there is increased release of placental syncytiotrophoblast extracellular vesicles (STBEVs) and free foetal haemoglobin (HbF) into the maternal circulation. In the present study we investigated the uptake of normal and PE STBEVs by primary human coronary artery endothelial cells (HCAEC) and the effects of free HbF on this uptake. Our results show internalization of STBEVs into primary HCAEC, and transfer of placenta specific miRNAs from STBEVs into the endoplasmic reticulum and mitochondria of these recipient cells. Further, the transferred miRNAs were functional, causing a down regulation of specific target genes, including the PE associated gene fms related tyrosine kinase 1 (FLT1). When co-treating normal STBEVs with HbF, the miRNA deposition is altered from the mitochondria to the ER and the cell membrane becomes ruffled, as was also seen with PE STBEVs. These findings suggest that STBEVs may cause endothelial damage and contribute to the endothelial dysfunction typical for PE. The miRNA mediated effects on gene expression may contribute to the oxidative and endoplasmic reticulum stress described in PE, as well as endothelial reprogramming that may underlay the increased risk of cardiovascular disease reported for women with PE later in life
