Pulsed electric field and salvia officinalis l. Leaves: A successful combination for the extraction of high value added compounds
(2021)The present study aimed to evaluate the pulsed electric field (PEF)-assisted extraction of phytochemicals from Salvia officinalis L. leaves. The study parameters included a PEF pulse duration of 10 or 100 µs for 30 min, ... -
Pulsed Electric Field Extraction of α and β-Acids From Pellets of Humulus lupulus (Hop)
(2020)This paper investigates the process of extracting hop pellets (hops) utilizing the pulsed electric field (PEF) technique and the contrasting effects of the technique between two distinct hop varieties (one bitter and one ... -
Pulsed electric field: A “green” extraction technology for biomolecular products from glycerol with fermentation of non-Saccharomyces yeasts
(2022)Glycerol is the main organic by-product of the biodiesel industry and it can be a source of carbon for fermentations or a substrate for biotransformations. This work investigates a process that uses pulsed electric field ... -
Pulsed electromagnetic field: an organic compatible method to promote plant growth and yield in two corn types
(2012)Pre-sowing treatment of pulsed electromagnetic fields was used in corn seeds, in both indoor and outdoor conditions, in order to investigate the effect on plant growth and yield. The results of this research showed that ... -
Pulsed electromagnetic fields effect in oregano rooting and vegetative propagation: A potential new organic method
(2012)Many types of magnetic fields have already been investigated in order to find new methods to enhance plant growth. This study reports the positive effect of pulsed electromagnetic field on the main root characteristics ... -
Punitive Limb Amputation
(2014)Limb amputation has been carried out through the ages as a punitive method in various parts of the world. This article highlights the historical and societal background associated with the use of punitive limb amputation. ... -
Pupils' understanding of air pollution
(2007)This paper reports on a study of pupils' knowledge and understanding of atmospheric pollution. Specifically, the study is aimed at identifying: 1) the extent to which pupils conceptualise the term 'air pollution' in a ... -
Purification of a candidate gonadotrophin surge attenuating factor from human follicular fluid
(1999)Gonadotrophin surge attenuating factor (GnSAF) is a new non-steroidal ovarian substance, different from inhibin, which attenuates the pre-ovulatory luteinizing hormone (LH) surge in superovulated women. Human follicular ... -
Pursuing a software defined information-centric network
(2012)The areas of Software-Defined Networking (SDN) and Information-Centric Networking (ICN) have gained increasing attention in the wider research community, while gaining credibility through corporate interest and investment. ... -
Purulent flexor tenosynovitis: Factors influencing the functional outcome
(2008)This retrospective study aimed to evaluate the factors that influence the final outcome of treatment of purulent flexor tenosynovitis, viz. delay in treatment, severity of the condition, the infecting pathogen and the ... -
Pus1p-dependent tRNA Pseudouridinylation Becomes Essential When tRNA Biogenesis Is Compromised in Yeast
(2001)Yeast Pus1p catalyzes the formation of pseudouridine (ψ) at specific sites of several tRNAs, but its function is not essential for cell viability. We show here that Pus1p becomes essential when another tRNA: pseudouridine ... -
A putative endophytic Bacillus cereus str. S42 from Nicotiana glauca for biocontrol of Fusarium wilt disease in tomato and gas chromatography-mass spectrometry analysis of its chloroform extract
(2016)A putative endophytic Bacillus cereus str. S42 (KP993206), recovered from surface-sterilised stems of Nicotiana glauca was assessed in vitro and in vivo for its antifungal potential towards Fusarium oxysporum f. sp. ... -
The putative interplay between DJ-1/NRF2 and Dimethyl Fumarate: A potentially important pharmacological target
(2018)Recent research has outlined that Dimethyl Fumarate (DMF) functions as a gene regulator via multiple pathways, critical among which is the NRF2 cytoprotective cascade. PARK7/DJ-1 is a multifunctional protein that acts as ... -
PyPUT: Python-based Placement Utilities Toolset
(2018)In the placement stage of a standard-cell design flow, a set of cells must be placed within a specified rectangular region, that may contain obstacles, in such a way that overlaps and overflows are non-existent and a target ... -
Pyricularia leaf spot: A new disease of ornamental plants of the family Marantaceae
(1998)A severe leaf spot disease incited by the fungus Pyricularia oryzae was identified on Ctenanthe oppenheimiana and C. setosa "Greystar." Primary symptoms on young leaves consisted of individual circular to slightly irregular ... -
Pyridoxine, folate and cobalamin for migraine: A systematic review
(2020)There is a possible relationship between migraine and hypercoagulability inducing factors, such as hyperhomocysteinemia. In this context, homocysteine (Hcy)-lowering vitamins (B6-folate-B12) may prove beneficial in the ... -
Pyrolytic laser-based chemical vapour deposition of TiC coatings
(1995)TiC layers have been successfully deposited locally on D2 tool steel specimens and miniature industrial tools with the aim to improve their mechanical and chemical surface properties. The deposition process was based on a ... -
Pyruvate dehydrogenase phosphatase 1 (PDP1) stimulates HIF activity by supporting histone acetylation under hypoxia
(2022)Cancer cells, when exposed to the hypoxic tumour microenvironment, respond by activating hypoxia-inducible factors (HIFs). HIF-1 mediates extensive metabolic re-programming, and expression of HIF-1α, its oxygen-regulated ... -
