Slowly quenched, high pressure glassy B2O3 at DFT accuracy.

Modeling inorganic glasses requires an accurate representation of interatomic interactions, large system sizes to allow for intermediate-range structural order, and slow quenching rates to eliminate kinetically trapped structural motifs. Neither first principles-based nor force field-based molecular dynamics (MD) simulations satisfy these three criteria unequivocally. Herein, we report the development of a machine learning potential (MLP) for a classic glass, B2O3, which meets these goals well.

Chromosome number alterations cause apoptosis and cellular hypertrophy in induced pluripotent stem cell models of embryonic epiblast cells.

Chromosomal aneuploidies are a major cause of developmental failure and pregnancy loss. To investigate the possible consequences of aneuploidy on early embryonic development in vitro, we focused on primed pluripotent stem cells that are relatable to the epiblast of post-implantation embryos in vivo. We used human induced pluripotent stem cells (iPSCs) as an epiblast model and altered chromosome numbers by treating with reversine, a small-molecule inhibitor of monopolar spindle 1 kinase (MSP1) that inactivates the spindle assembly checkpoint, which has been strongly implicated in chromosome mis-segregation and aneuploidy generation.

Electrochemical immunosensor for PA toxin using a polypyrrole-gold nanoparticle/multiwall carbon nanotube sensing platform and cadmium sulphide nanocrystal signal tag.

A sandwich electrochemical immunosensor was proposed for the sensitive detection of protective antigen ( PA) toxin based on cadmium sulphide nanocrystals (CdS NCs) and polypyrrole-gold nanoparticle-modified multiwalled carbon nanotubes (PPy-AuNPs/MWCNTs). Herein, PPy-AuNPs/MWCNTs were used as a biocompatible and conducting matrix for immobilization of rabbit anti-PA antibody [RαPA antibody, capturing antibody (Ab1)] and to facilitate excellent electrical conductivity. PPy-AuNPs/MWCNTs were synthesized through a one-step chemical reaction of pyrrole and Au on the surface of MWCNTs.

Fast-Track Extubation in a Patient Undergoing Whole Lung Lavage: A Case Report.

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary pathology characterized by the accumulation of surfactant within type II alveolar epithelial cells. Whole lung lavage is the standard treatment for pulmonary alveolar proteinosis involving a large volume of fluid is infused into one lung and subsequently retrieved while the other lung is remains ventilated. Fast-tracking a patient undergoing whole lung lavage requires vigilant monitoring of arterial blood gases, fluid status, and respiratory mechanics.

Massive Hemothorax due to a Rare Entity: Dilemma of ICD Insertion!! A Case Report.

Intercostal artery aneurysms are a type of vascular abnormality that poses a potential risk of rupture, which could lead to life-threatening hemothorax. This case report presents a young male who experienced a rupture of an intercostal artery aneurysm and subsequently suffered from a massive hemothorax after engaging in strenuous physical activity. The current case study sheds light on the difficulties and lessons learned in managing such cases in peripheral settings, including the dilemma of whether to insert an intercostal chest drain (ICD).

A Case of Life-Threatening Contralateral Tension Pneumothorax during Video-Assisted Thoracic Surgery in a Patient with Retrosternal Goiter.

We report a case of a 74-year-old female with a retrosternal goiter undergoing video-assisted thoracic surgery (VATS) for a left lung lower lobectomy, necessitating one-lung ventilation (OLV). We encountered a highly unusual complication: contralateral tension pneumothorax. Forty-five minutes into the surgical procedure, a sudden cardiovascular collapse occurred.

A Comprehensive Clinical Acumen Enhanced by Point-of-Care Ultrasonography in Managing Acute Life-Threatening Massive Pulmonary Thromboembolism in a Peripheral Setting: A Case Report.

Acute massive pulmonary thromboembolism (PTE) is a potentially life-threatening condition requiring urgent management to decrease mortality. However, in the peripheral setting, managing the emergency can be challenging. We report a case of massive PTE presenting with cardiopulmonary arrest, successfully managed with advanced cardiac life support, early initiation of anticoagulants (heparin), and thrombolytics.

Accuracy of Intraoperative Transesophageal Echocardiographic Doppler Parameters in Assessing the Right Ventricular Diastolic Function After Repair of Tetralogy of Fallot in Pediatric Patients.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.

Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.

Comparative Evaluation of Regain of Consciousness in Dexmedetomidine-Propofol versus Ketamine-Propofol in the Pediatric Cardiac Catheterization Procedure under Sedation using BIS Monitoring: A Randomized Prospective Study.

Background: Congenital heart diseases (CHDs) are not rare and often require an intervention at some point of time. Pediatric cardiac catheterization, a minimally invasive procedure, is performed to diagnose and to correct many cardiac abnormalities. Deep sedation with spontaneously breathing patients is the preferred technique for pediatric catheterization in the pediatric population.

Role of Intraoperative Left Ventricular Global Longitudinal Strain in Hemodynamic and Cognitive Outcomes in On-Pump Coronary Artery Bypass Surgery: A Prospective Observational Study.

Background: The role of left ventricular global longitudinal strain (LVGLS) in coronary artery bypass grafting (CABG) and outcomes such as low cardiac output syndrome (LCOS) is not well established. The authors investigated the relationship between LVGLS before and after induction of anesthesia, their differences, and their relationship with LCOS and other outcomes.

Methodology: A prospective observational study was conducted in a public/private hospital with 50 adult patients scheduled for on-pump CABG with normal left ventricular ejection fraction (LVEF).

Our Experience of Managing Central Airway Tumors: Anesthesia Perspectives.

Adult patients with central airway tumors commonly present with dyspnea on exertion. These patients may remain asymptomatic until more than half of the airway diameter is obliterated. Anesthesia for debulking a central airway tumor is challenging.
