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 ... -
PZT and PVDF piezoelectric transducers' design implications on their efficiency and energy harvesting potential
(2022)Despite the intensive research carried out in the last two decades, the actual performance of piezoelectric energy harvesters needs significant improvement for widespread applicability. Custom designed experimental set-ups ... -
Q fever and prevalence of Coxiella burnetii in milk
(2018)Background Q fever is a zoonosis caused by Coxiella burnetii. In humans, although it has been predominantly considered an occupational hazard, in the last decades, Q fever outbreaks have also been reported in various ... -
Q fever and seroprevalence of Coxiella burnetii in domestic ruminants
(2018)Q fever is a zoonosis caused by Coxiella burnetii, an obligate intracellular gram‑negative bacterium. Infection by C. burnetii has been demonstrated in many animal species, but ruminants are the major reservoirs and the ... -
QAM and PSK OFDM RoFSO Over M-Turbulence Induced Fading Channels
(2015)Free-Space Optical (FSO) technology can effectively transfer multiple radio-frequency signals, and this new technique is commonly referred in the technical literature as radio on FSO (RoFSO). In the present study, we ... -
QoE-Aware Edge Computing Through Service Function Chaining
(2022)Mobile multimedia Internet services, such as mobile virtual reality (VR), request for advanced quality of experience (QoE) provision. In the future Internet, such a QoE provision will be leveraged through edge computing, ... -
QoS and MPLS design issues in NoCs
(2018)Nowadays real application traffic, and especially streaming applications running in multi core environments require more and more bandwidth. Networks on Chips (NoC) should be able not only to provide adequate bandwidth ... -
QoS of Web Services in SOA Systems
(2014)Web services are a major part of today’s networks and internet based applications. There is a wide variety of web services and development of new ones takes place constantly. End users are called to select from a multitude ... -
A QoS-Aware, Proactive Tasks Offloading Model for Pervasive Applications
(2022)Edge Computing (EC) is a promising paradigm that provides multiple computation and analytics capabilities close to data sources while alleviating the drawbacks of centralized systems. Nonetheless, due to the limited ... -
