Objectives: To determine whether plaque composition analysis defined by cardiac CT can provide incremental prognostic value above coronary artery disease (CAD) burden markers in symptomatic patients with obstructive CAD.

Materials And Methods: Between 2009 and 2019, a multicentric registry included all consecutive symptomatic patients with obstructive CAD (at least one ≥ 50% stenosis on CCTA) and was followed for major adverse cardiovascular (MACE) defined by cardiovascular death or nonfatal myocardial infarction. Each coronary segment was scored visually for both the degree of stenosis and composition of plaque, which were classified as non-calcified, mixed, or calcified.

  • Sodium chloride (NaCl) is significant across various fields, including geochemistry and food production, and is one of the most prevalent salts in the cosmos.
  • Researchers discovered a new form of NaCl, a metastable dihydrate, created by rapidly freezing a NaCl solution, which transforms into hydrohalite and ice Ih when heated above 190 K.
  • This finding suggests that the presence of this new hydrate on icy celestial bodies, like Jupiter and Saturn's moons, could indicate areas where subsurface brines have recently frozen, highlighting potential targets for future space missions.

is a fungus that causes charcoal rot in strawberry and a wide variety of crop species. Little is known about its potential to asymptomatically colonize crop plants or grow saprophytically on their tissues, both of which would create a potential for alternate, asymptomatic hosts to lead to increases in inoculum. To test the impact of cover cropping on abundance, we conducted randomized-block field experiments in soils infested by .

The eco-epidemiology of tick-borne diseases hinges on the abundance and distribution of hosts that sustain tick populations and the pathogens they carry. Research into the role of bird species in the feeding of Ixodes ricinus ticks, the primary tick species of veterinary and public health importance in Europe, remains scarce. This study endeavors to bridge these knowledge gaps by (i) assessing the density of feeding ticks (DFT) within a bird community to pinpoint species making substantial contributions, and (ii) exploring interannual variations in DFT over an extended timeline.

Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been explored. With increasing regulatory demand for New Approach Methods (NAMs) that use alternatives to animal models and high-content approaches such as transcriptomics, this type of comparative analysis is needed.

Due to their distinct and tailorable internal cavity structures, zeolites serve as promising materials for efficient and specific gas separations such as the separation of /CO from N. A subset of zeolite materials exhibits trapdoor behavior which can be exploited for particularly challenging separations, such as the separation of hydrogen, deuterium, and tritium for the nuclear industry. This study systematically delves into the influence of the chabazite (CHA) and merlinoite (MER) zeolite frameworks combined with different door-keeping cations (K, Rb, and Cs) on the trapdoor separation behavior under a variety of thermal and gas conditions.

Phenological adjustment is the first line of adaptive response of vertebrates when seasonality is disrupted by climate change. The prevailing response is to reproduce earlier in warmer springs, but habitat changes, such as forest degradation, are expected to affect phenological plasticity, for example, due to loss of reliability of environmental cues used by organisms to time reproduction. Relying on a two-decade, country-level capture-based monitoring of common songbirds' reproduction, we investigated how habitat anthropization, here characterized by the rural-urban and forest-farmland gradients, affected the average phenology and plasticity to local temperature in two common species, the great tit Parus major and the blue tit Cyanistes caeruleus.

  • Localized shimming in single-voxel MRS can cause significant B inhomogeneity outside the targeted area, impacting image quality during motion correction.
  • A modified fast motion navigator was developed to address these issues by using multiple shot interleaves, resulting in improved image quality while maintaining a short scanning duration.
  • This approach allows effective motion correction for MRS by reducing the impact of B inhomogeneity, leading to better spectral quality in both stationary and moving subjects.

Synchronous variation in demographic parameters across species increases the risk of simultaneous local extinction, which lowers the probability of subsequent recolonization. Synchrony therefore tends to destabilize meta-populations and meta-communities. Quantifying interspecific synchrony in demographic parameters, like abundance, survival, or reproduction, is thus a way to indirectly assess the stability of meta-populations and meta-communities.

Article Synopsis
  • The study investigated the prognostic value of the TAPSE/sPAP ratio in patients hospitalized for acute coronary syndrome (ACS), focusing on its link to in-hospital major adverse cardiovascular events (MACEs).
  • In a cohort of 481 patients, a TAPSE/sPAP ratio below 0.55 was found to significantly predict the occurrence of MACEs, with odds ratios indicating a very strong association even after accounting for other health factors.
  • The findings highlight that a lower TAPSE/sPAP ratio improves risk assessment beyond conventional factors, suggesting it could serve as a critical marker for patient prognosis during hospitalization for ACS.
