Ruprecht 147, the oldest nearby open cluster association, which was photometrically monitored by K2 during its Campaign 7. We combine the K2 time-series data with ground-based adaptive optics imaging and high-resolution spectroscopy to rule out false positive scenarios and determine the main parameters of the system. EPIC 219388192b has a radius of Rb= 0.937 ± 0.032 RJup and mass of Mb = 36.84 ± 0
We report the discovery from K2 of a transiting planet in an 18.25-d, eccentric (0.19 ± 0.04) orbit around K2-99, an 11th magnitude subgiant in Virgo. We con- firm the planetary nature of the companion with radial velocities, and determine that the star is a metal-rich ([Fe/H] = 0.20 ± 0.05) subgiant, with mass 1.60+0.14 -0.10 M⊙ and radius 3.1 ± 0.1 R⊙. The planet has a mass of 0.97 ± 0.09 MJup a
We report the discovery of K2-98b (EPIC 211391664b), a transiting Neptune-size planet monitored by the K2 mission during its Campaign 5. We combine the K2 time-series data with ground-based photometric and spectroscopic follow-up observations to confirm the planetary nature of the object and derive its mass, radius, and orbital parameters. K2-98b is a warm Neptune-like planet in a 10 day orbit aro
We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HARPS high-resolution spectroscopy to confirm the planetary nature of the transiting object and derived the system parameters. K2-31b is a 1.8-Jupiter-mass planet on 1.26-day orbit around a G7 V star (M∗ = 0.91 M⊙, R∗ = 0.
We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measurements from FIES@NOT, HARPS-N@TNG, and the coudé spectrograph on the McDonald Observatory 2.7 m telescope. K2-29 b (EPIC 211089792b) transits a K1V star with a period of 3.2589263 ± 0.0000015 days; its orbit is slightly ecce
Context. We present the discovery of two transiting extrasolar planets by the satellite CoRoT. Aims. We aim at a characterization of the planetary bulk parameters, which allow us to further investigate the formation and evolution of the planetary systems and the main properties of the host stars. Methods. We used the transit light curve to characterize the planetary parameters relative to the stel
Aims. We report the discovery of a massive and dense transiting planet CoRoT-27b on a 3.58-day orbit around a 4.2 Gyr-old G2 star. The planet candidate was identified from the CoRoT photometry, and was confirmed as a planet with ground-based spectroscopy. Methods. The confirmation of the planet candidate is based on radial velocity observations combined with imaging to rule out blends. The charact
AimEndometriosis is one of the most common gynecologic diseases in women of reproductive age. The pathophysiology of endometriosis is still not fully understood. Phoenixin (PNX-14) is a newly discovered neuropeptide that regulates the hypothalamo–pituitary–gonadal (HPG) axis and reproductive functions. Recently, we reported that PNX-14, its precursor protein and receptor were expressed in human en
Recent developments in neuroscience and artificial intelligence have allowed machines to decode mental processes with growing accuracy. Neuroethicists have speculated that perfecting these technologies may result in reactions ranging from an invasion of privacy to an increase in self-understanding. Yet, evaluating these predictions is difficult given that people are poor at forecasting their react
Lunds Botaniska Förening och Eslövs kommun har genomfört ett LONA-projekt 2020–2022 inom vilket kommunens ansvarsarter humlesuga, Betonica offi- cinalis L., och kärrnäva, Geranium palustre L., har odlats och planterats på reservlokaler. Även ängs- skära, Serratula tinctoria L., och gullstånds, Jaco- baea paludosa (L.) P. Gaertn., har ingått i projektet. Antalet spontana exemplar i kommunen uppgickA LONA (local nature conservation support) project administrated by Eslöv town in cooperation with Lund Botanical Society was undertaken in 2020– 2022 to determine the status of the protected plant species Betony (Betonica officinalis L.) and Marsh Crane’s-bill (Geranium palustre L.) in natural popu- lations. The second main goal of the project was to establish the species in planted back-up local
Stagnelius och Rydstedts dikter delar en starkt dualistisk syn på tillvaron. Den kan i båda fallen knytas till Johannesevangeliets också starkt dualistiska värld. Rydstedt använder i sina dikter både Stagnelius och Johannesevangeliet; här utreds hennes bruk av stagnelianska formuleringar. I alla tre fallen övervinns den starka dualismen på delvis olika sätt.
Bone morphogenetic proteins (BMP) are powerful regulators of cellular processes such as proliferation, differentiation, and apoptosis. However, the specific molecular requirements controlling the bioavailability of BMPs in the extracellular matrix (ECM) are not yet fully understood. Our previous work showed that BMPs are targeted to the ECM as growth factor-prodomain (GF-PD) complexes (CPLXs) via
To stay within planetary boundaries, we need to move into sustainable levels of resource consumption, or sufficiency. Businesses can play a key role in driving sufficiency as they satisfy and also create demand. This article investigates how a bicycle subscription company can promote sufficiency among its users, with a focus on modal shift and product care. It aims to fill the research gap on how
Background: Failed management of unanticipated difficult airway situations contributes to significant anesthesia-related morbidity and mortality. Optimization of design and layout of difficult airway trolleys (DATs) may influence outcomes during airway emergencies. The main objective of the current study was to evaluate whether a difficult airway algorithm-based DAT with integrated cognitive aids
We report on the development of a method based on recombinant yeast Saccharomyces cerevisiae to produce nonivamide, a capsaicinoid and potent agonist of the pain receptor TRPV1. Nonivamide was produced in a two-step batch process where yeast was i) grown aerobically on glucose and ii) used to produce nonivamide from vanillin and non-anoic acid by bioconversion. The yeast was engineered to express
In transplants of embryonic striatal cells placed into the excitotoxically lesioned rat striatum (a model of Huntington's disease), as many as 60 to 90% of the grafted cells are believed to die. Caspase activation is part of a cascade of events that can lead to apoptosis. We investigated the effect of the caspase inhibitor acetyl-tyrosinyl-valyl-alanyl-aspartyl-chloromethylketone (Ac-YVAD-cmk) on In transplants of embryonic striatal cells placed into the excitotoxically lesioned rat striatum (a model of Huntington's disease), as many as 60 to 90% of the grafted cells are believed to die.

As structural components of the glycocalyx, heparan sulfate proteoglycans (HSPGs) are involved in multiple pathophysiological processes at the apex of cell signaling cascades, and as endocytosis receptors for particle structures, such as lipoproteins, extracellular vesicles, and enveloped viruses, including SARS-CoV-2. Given their diversity and complex biogenesis regulation, HSPGs remain understud
A large proportion of grafted striatal neurons die, and mechanisms by which they succumb may involve excitotoxicity and oxidative stress. We investigated the effects of pretreatment of the graft tissue with the N-methyl-D-aspartate (NMDA) receptor antagonist (+)dizocilpine hydrogen maleate (MK-801) and lipid peroxidation inhibitor lazaroid U-83836E on the survival of transplanted striatal neurons.
