UnknownIdentification of a unique endoplasmic retention motif in the Xenopus GIRK5 channel and its contribution to oocyte maturation.
G protein-activated inward-rectifying potassium (K+ ) channels (Kir3/GIRK) participate in cell excitability. The GIRK5 channel is present in Xenopus laevis oocytes. In an attempt to investigate the physiological role of GIRK5, we identified a noncanonical di-arginine endoplasmic reticulum...

UnknownHeating Efficiency of Different Magnetotactic Bacterial Species: Influence of Magnetosome Morphology and Chain Arrangement.
Magnetotactic bacteria have been proposed as ideal biological nanorobots due to the presence of an intracellular chain of magnetic nanoparticles (MNPs), which allows them to be guided and controlled by external magnetic fields and provides them with theragnostic capabilities intrinsic to magnetic na...

UnknownMortality of metallo-β-lactamase-producing Enterobacterales bacteremias with combined ceftazidime-avibactam plus aztreonam vs. other active antibiotics: a multicenter target trial emulation.

Background

Bacteremias caused by metallo-β-lactamase (MBL)-producing Enterobacterales are a critical challenge due to their limited treatment options. Although ceftazidime-avibactam (CAZAVI) combined with aztreonam (ATM) has shown in vitro efficacy, no prior studies have rigorously compared ...

UnknownComplete Chloroplast Genome of an Endophytic Ostreobium sp. (Ostreobiaceae) from the U.S. Virgin Islands.
We present the complete chloroplast genome sequence of an endophytic Ostreobium sp. isolated from a 19th-century coralline red algal specimen from St. Croix, U.S. Virgin Islands. The chloroplast genome is 84,848 bp in length, contains 114 genes, and has a high level of gene synteny to other O...

UnknownEffect of High-Flow Oxygen Therapy vs Conventional Oxygen Therapy on Invasive Mechanical Ventilation and Clinical Recovery in Patients With Severe COVID-19: A Randomized Clinical Trial.

Importance

The effect of high-flow oxygen therapy vs conventional oxygen therapy has not been established in the setting of severe COVID-19.

Objective

To determine the effect of high-flow oxygen therapy through a nasal cannula compared with conventional oxygen therapy on need for endo...

UnknownThe evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients.

Background

Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at...

UnknownRisk factors for developing ventilator-associated lower respiratory tract infection in patients with severe COVID-19: a multinational, multicentre study, prospective, observational study.
Around one-third of patients diagnosed with COVID-19 develop a severe illness that requires admission to the Intensive Care Unit (ICU). In clinical practice, clinicians have learned that patients admitted to the ICU due to severe COVID-19 frequently develop ventilator-associated lower respiratory tr...

UnknownCancer therapy shapes the fitness landscape of clonal hematopoiesis.
Acquired mutations are pervasive across normal tissues. However, understanding of the processes that drive transformation of certain clones to cancer is limited. Here we study this phenomenon in the context of clonal hematopoiesis (CH) and the development of therapy-related myeloid neoplasms (tMNs)....

UnknownImpact of neuromuscular block monitoring and reversal on postoperative pulmonary complications in thoracic surgery: a Bayesian analysis of the iPROVE-OLV trial.

Background

Postoperative pulmonary complications (PPCs) are a significant concern in thoracic surgery. A modifiable factor influencing PPCs is postoperative residual neuromuscular block (NMB), which impairs respiratory muscle function.

Methods

We performed a post hoc Bayesian analysis...

UnknownSpatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions.
Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41-6.57%) across Spain. Our aim was to estimate the levels of regional clustering for ...
