Article Synopsis
  • This study examines the connection between frailty and mortality in elderly individuals, particularly focusing on those aged 90 and older.
  • It found that frail adults generally have a significantly lower overall survival rate compared to non-frail individuals, especially in those under 90 years old.
  • However, results were less conclusive for participants over 90, indicating that frailty's impact on mortality may vary by age and sex, with notable differences among older males.

Background: Published studies have suggested a link between chronic kidney disease (CKD) and sleep disorders, although the exact nature of this association has not been uniformly described. Clarifying this relationship may facilitate evidence-based interventions that address the interplay between these disease entities. Such interventions could prevent obstructive sleep apnea (OSA) from worsening CKD and improve the quality of life for CKD patients by reducing the risk of developing OSA.

  • The study looked at how atopic dermatitis (AD), a skin condition, can affect children's growth in height.
  • Researchers checked a lot of articles to see if kids with AD were shorter than those without, and found mixed results: some studies linked AD to being shorter, while others did not.
  • They found that kids with more severe AD, those who had it from a young age, had trouble sleeping, or had certain diet restrictions were more likely to have growth problems.

Background And Purpose: Tenecteplase is a thrombolytic agent with pharmacological advantages over alteplase and has been shown to be noninferior to alteplase for acute ischemic stroke in randomized trials. However, evidence pertaining to the safety and efficacy of tenecteplase in patients from different ethnic groups is lacking. The aim of this systematic review and metaanalysis was to investigate ethnicity-specific differences in the safety and efficacy of tenecteplase versus alteplase in patients with acute ischemic stroke.

Article Synopsis
  • The OCCUPI trial aimed to determine if optical coherence tomography (OCT) guidance during percutaneous coronary intervention (PCI) provides better clinical outcomes compared to traditional angiography guidance for complex heart lesions over a year.
  • Conducted across 20 hospitals in South Korea, the trial included 1,604 patients aged 19-85 and utilized randomization to assign participants to either OCT or angiography guidance during their PCI procedure.
  • The main outcome measured was the rate of major adverse cardiac events, but the effectiveness of OCT guidance in reducing these events compared to angiography guidance remains uncertain, as the study was designed to assess potential clinical benefits.

Programmable quantum simulators may one day outperform classical computers at certain tasks. But at present, the range of viable applications with noisy intermediate-scale quantum (NISQ) devices remains limited by gate errors and the number of high-quality qubits. Here, we develop an approach that places digital NISQ hardware as a versatile platform for simulating multi-dimensional condensed matter systems.

Passiflora edulis, commonly known as passion fruit, is a crop with a fragrant aroma and refreshingly tropical flavor that is a valuable source of antioxidants. It offers a unique opportunity for growers because of its adaptability to tropical and subtropical climates. Passion fruit can be sold in the fresh market or used in value-added products, but its postharvest shelf life has not been well-researched, nor have superior cultivars been well-developed.

Polyploidy is an important evolutionary process throughout eukaryotes, particularly in flowering plants. Duplicated gene pairs (homoeologs) in allopolyploids provide additional genetic resources for changes in molecular, biochemical, and physiological mechanisms that result in evolutionary novelty. Therefore, understanding how divergent genomes and their regulatory networks reconcile is vital for unraveling the role of polyploidy in plant evolution.

Nucleases are strictly regulated and often localized in the cell to avoid the uncontrolled degradation of DNA and RNA. Here, a new type of nuclease complex, composed of RecJ3, RecJ4, and aRNase J, was identified through its ATP-dependent association with the ubiquitin-like SAMP1 and AAA-ATPase Cdc48a. The complex was discovered in , an archaeon lacking an RNA exosome.

Non-hermiticity presents a vast newly opened territory that harbors new physics and applications such as lasing and sensing. However, only non-Hermitian systems with real eigenenergies are stable, and great efforts have been devoted in designing them through enforcing parity-time (PT) symmetry. In this work, we exploit a lesser-known dynamical mechanism for enforcing real-spectra, and develop a comprehensive and versatile approach for designing new classes of parent Hamiltonians with real spectra.
