Rapid spontaneous alloying between Pd nanocubes and spherical or triangular Ag nanoparticles was studied in an aqueous solution at ambient temperature using transmission electron microscopy (TEM), TEM-energy-dispersed X-ray spectroscopy (EDS), XRD, and UV-Vis spectroscopy of product particles. The results show that alloying occurs between Ag particles and Pd cubes and finishes within a few seconds, preserving the cubic shape with maximum Ag content of approximately 22%.

The purpose of this work is to evaluate the feasibility of lung imaging using 3D electrical impedance tomography (EIT) during spontaneous breathing trials (SBTs) in patients with acute hypoxic respiratory failure. EIT is a noninvasive, nonionizing, real-time functional imaging technique, suitable for bedside monitoring in critically ill patients. EIT data were collected in 24 mechanically ventilated patients immediately preceding and during a SBT on two rows of 16 electrodes using a simultaneous multicurrent source EIT system for 3D imaging.

Acute generalized exanthematous pustulosis (AGEP) is a rare drug eruption characterized by the rapid occurrence of many sterile, non-follicular pustules, neutrophilic leukocytosis, high fever and spontaneous resolution usually within two weeks. The distribution of rash predilection in the trunk and intertriginous regions. In treatment, the causative drug must be initially discontinued.

Background: Numerous noncontrast computed tomography (NCCT) markers have been reported and validated as effective predictors of hematoma expansion (HE). Our objective was to develop and validate a score based on NCCT markers and clinical characteristics to predict risk of HE in acute intracerebral hemorrhage (ICH) patients.
Methods: We prospectively collected spontaneous ICH patients at the First Affiliated Hospital of Chongqing Medical University to form the development cohort (n = 395) and at the Third Affiliated Hospital of Chongqing Medical University to establish the validation cohort (n = 139).

Developing Countries Vaccine Manufacturers Network (DCVMN) is an alliance of vaccine developers, manufacturers, and marketing authorization holders (MAHs) from low- and middle-income countries (LMICs) that plays a vital role in ensuring equitable, inclusive, accountable, and timely access to affordable, high-quality vaccines in these countries. Besides research and development, this network promotes manufacturing and global supply chains for effective strengthening of regulatory and pharmacovigilance activities. Traditionally, vaccine safety surveillance systems in LMICs rely on spontaneous reporting.

Necrotizing fasciitis is a potentially life-threatening infection that can lead to rapid muscular and fascial necrosis, often resulting in sepsis. In addition to the rapid disease progression, diagnosing this disease in children can be challenging as they cannot accurately communicate their symptoms. Spontaneous necrotizing fasciitis secondary to Clostridial infection has rarely been described in the literature but occurs in neutropenic patients with significant morbidity and mortality from myonecrosis and gas gangrene.
