Resultat av försök som utfördes under oktober-november 1996 med elektroporering av senapsfrön i olika förbehandlingsmedier. Fröernas groning försämras med ökad koncentration av kalciumjoner i förbehandlingsmediet. Ju högre nivå av CaCI2, desto högre känslighet för elektroporering.
Differences in public health approaches to control the coronavirus disease 2019 (COVID-19) pandemic could largely explain substantial variations in epidemiological indicators (such as incidence and mortality) between the West and the East. COVID-19 revealed vulnerabilities of most western countries' healthcare systems in their response to the ongoing public health crisis. Hence, western countries
A growing number of connected IoT devices makesit more and more difficult for the network to provide the desiredreliability in any deployment scenario. The advent of NB-IoTtechnology opens new possibilities for low-power long-range IoTapplications. However, the design of the standard introduces highbattery drainage in the situations when the radio conditionsbetween the UE and the eNB are poor. Dev
Discontinuous Reception (DRX) has been included in 4G-LTE as the main power saving mechanism for User Equipment (UE). However, the existing 3-state DRX model is not sufficient for new use cases introduced by 4G and 5G. For example, the device discovery process in Device to Device (D2D) communication has a significant impact on delay and power consumption, but the existing conventional 3-state DRX
Context. Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show a strong correlation between their orbital periods and mass ratios. The origins of this correlation have, so far, been lacking a conclusive explanation. Aims. We aim to find a binary evolution model which can explain the observed
Biochar produced in cookstoves has the potential to contribute to negative carbon emissions through sequestration of biomass carbon while also providing other benefits for sustainable development, including provision of clean renewable energy and increased yields in tropical agriculture. The aim of the reported research was to estimate effects on food production, household energy access and life c
Although progress has been made to improve access to sexual and reproductive health services globally in the past two decades, in many low-income countries, improvements have been slow. Discrimination against vulnerable groups and failure to address health inequities openly and comprehensively play a role in this stagnation. Healthcare practitioners are important actors who, often alone, decide wh
Abdominal aortic aneurysm (AAA) is a life-threatening condition with a mortality rate of over 80%. Persistent smoking, which is a risk factor for AAA, has lasting effects on DNA methylation. Moreover, a plasma-amino acid, homocysteine, previously implicated in vascular diseases, including aneurysms, has well-established biological association with methylation. In the present study, we aimed to det
BACKGROUND: Biofilm formation on endotracheal tubes (ETTs) is an early and frequent event in mechanically ventilated patients. The biofilm is believed to act as a reservoir for infecting microorganisms and thereby contribute to development and relapses of ventilator-associated pneumonia (VAP). Once a biofilm has formed on an ETT surface, it is difficult to eradicate. This clinical study aimed to c
Axially heterostructured nanowires are a promising platform for next generation electronic and optoelectronic devices. Reports based on theoretical modeling have predicted more complex strain distributions and increased critical layer thicknesses than in thin films, due to lateral strain relaxation at the surface, but the understanding of the growth and strain distributions in these complex struct
Using light to interact with cells is a promising way to steer cell behavior with minimal perturbation. Besides optogenetics, photovoltaic nanostructures such as nanowires can be used to interact with cells using light as a switch. Photovoltaic nanowires have, for instance, been used to stimulate neurons. However, the effects of the photovoltaic activity on cells are still poorly understood and ch
Promoting young children's health through health promotion activities is an investment for the future. In the Child Health Services in the south of Sweden a structured Child-Centred Health Dialogue (CCHD) directed to all 4-year-old children was developed using illustrations based on the most important health messages associated with the promotion of healthy lifestyle in preschool children. The aim
This work provides new insights into the presence of 239Pu, 240Pu, 241Pu, and 236U in the Southern Hemisphere through the study of peat bog cores from marshlands in Madagascar (19°S). 210Pb, 238Pu and 239+240Pu activities were characterized by alpha spectrometry in previous studies. Here, Pu from alpha-spectrometry discs corresponding to 10 peat-bog cores (85 samples) was reassessed for the aim of
ObjectiveThe quality of cardiopulmonary resuscitation (CPR) affects outcomes from cardiac arrest, yet manual CPR is difficult to administer. Although mechanical CPR (mCPR) devices offer high quality CPR, only limited data describe their deployment, their interaction with standard manual CPR (sCPR), and the consequent effects on chest compression continuity and patient outcomes. We sought to descri
Background: The LUCAS™ device delivers mechanical chest compressions that have been shown in experimental studies to improve perfusion pressures to the brain and heart as well as augmenting cerebral blood flow and end tidal CO2, compared with results from standard manual cardiopulmonary resuscitation (CPR). Two randomised pilot studies in out-of-hospital cardiac arrest patients have not shown impr
Background: Accumulating data support the role of flow cytometry (FCM) in diagnostic work-up of myelodysplastic syndromes (MDS). Changes in erythropoiesis are less documented than in granulopoiesis. However, most studies were performed on bone marrow samples (BMSs) after red blood cell lysis. We have established a FCM protocol for erythropoiesis, following a no-lysis approach and live gate acquisi
Pregnancy leads to adaptations for maternal and fetal energy needs. The cardiovascular system bears the brunt of the adaptations as the heart and vessels enable nutrient supply to maternal organs facilitated by the placenta to the fetus. The components of the cardiovascular system are critical in the balance between maternal homeostatic and fetus driven homeorhetic regulation. Since lipids interse
