Targeted Ganglionated Plexi Ablation With Nanoformulated Calcium Suppresses Postoperative AF Via Vagosympatholytic and Anti-Inflammatory Effects.

Background: The mechanisms underlying postoperative atrial fibrillation (POAF) remain unclear.

Objectives: The aim of this study was to test the hypothesis that targeted chemical ganglionated plexi (GP) modulation of all major left atrial-pulmonary vein GP using novel nanoformulated calcium chloride (nCaCl) can reverse postoperative neuroelectrical remodeling by suppressing vagosympathetic nerve activity and the localized inflammatory process, both critical substrates of POAF.

Methods: In a novel canine model of POAF with serial thoracopericardiotomies, sympathetic nerve activity (SNA), vagal nerve activity (VNA) and GP nerve activity (GPNA) were recorded; spontaneous and in vivo AF vulnerability were assessed; and atrial and circulating inflammatory markers and norepinephrine (NE) were measured to determine the neuroelectrical remodeling that promotes POAF and its subsequent modulation with nCaCl GP treatment (n = 6) vs saline sham controls (n = 6).

Enterococcus avium Infection After Liver Transplantation in Vietnam: A Case Report.

Background: The infectious complications are the most common and can be life-threatening to liver transplant recipients, in particular, within the first month after transplantation. Early diagnosis of these severe complications and accurate detection of causative etiologies are crucial for the choice of therapeutic strategies and management of liver transplants.

Case Report: We present a case report of a patient with a history of primary sclerosing cholangitis who underwent a liver transplantation (LT) from a living donor.

Pharmacogenomic variation and sedation outcomes during early intensive care unit admission: A pragmatic study.

Unpredicted responses to sedatives and analgesics are common in critically ill patients on mechanical ventilation (MV) and may be attributed to genetic variation. Our primary aim was to investigate the association between the pharmacogenomic (PGx) variation and sedation outcomes. The secondary aim was to capture intensive care unit (ICU) participants' perceptions of PGx.

Inhibitors of acetohydroxyacid synthase as promising agents against non-tuberculous mycobacterial diseases.

Acetohydroxyacid synthase (AHAS), exclusively present in microorganisms and plants, is a promising target for several herbicides due to its catalytic role in the branched-chain amino acid biosynthetic pathway. Previous studies have shown that K13787, a pyrazolopyrimidine sulfonamide AHAS inhibitor, was moderately effective against pulmonary infection caused by M. tuberculosis and nontuberculous mycobacteria (NTM).

Discovery and engineering of the antibody response to a prominent skin commensal.

The ubiquitous skin colonist Staphylococcus epidermidis elicits a CD8 T cell response pre-emptively, in the absence of an infection. However, the scope and purpose of this anti-commensal immune program are not well defined, limiting our ability to harness it therapeutically. Here, we show that this colonist also induces a potent, durable, and specific antibody response that is conserved in humans and non-human primates.

Interleukin-12 decorated nanosized semiflexible Immunofilaments enable directed targeting and augmented IFNγ responses of natural killer cells.

Immunotherapies are a powerful strategy to treat cancer by modulating the immune system to raise an anti-tumor immune response. A prime example of immunotherapies are cytokines - small immunomodulatory molecules that are widely used to stimulate immune cells. Undirected administration of cytokines, however, can cause severe side effects, preventing the use of potent cytokines, such as Interleukin (IL)-12, which induces IFNγ responses by cytotoxic effector lymphocytes, including NK cells.

Efficacy and Tolerance of First-Line Afatinib in Elderly NSCLC Patients with EGFR Mutations in Vietnam: A Multicenter Real-World Study.

Background: Afatinib, a second-generation epidermal growth factor receptor(EGFR) tyrosine kinase, has proven effective for non-small-cell lung cancer (NSCLC) patients with EGFR mutations through randomized controlled trials and real-world studies. Elderly patients exhibit unique characteristics in terms of physical condition and comorbidities, leading to differences in clinical practice for selecting the initial dosage and making dose adjustments compared to younger patients. This study aims to evaluate the effectiveness and adverse effects of first-line Afatinib treatment in elderly patients with NSCLC harboring EGFR mutations in Vietnam in a real-world context.

Facile synthesis of a 3D magnetic graphene oxide/FeO/banana peel-derived cellulose composite aerogel for the efficient removal of tetracycline.

Many initiatives have incorporated graphene oxide (GO) and biomass into aerogels for wastewater treatment. We report on the facile fabrication of a magnetic GO/FeO/banana peel-derived cellulose (bio-cellulose) aerogel using an ultrasound-assisted mechanical mixing method and freeze-drying technique for the removal of tetracycline (TC). The component materials and composite aerogel were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), nitrogen adsorption-desorption analysis, and vibrating sample magnetometry (VSM).

Triple-chain boron clusters: lengthening phosphorus doping and enhancing stability through {P} by {CH} substitution.

This theoretical study presents novel insights into the doping of boron clusters with an increasing number of dopant atoms, ranging from 1 to 4, that preserve the integrity of the original boron framework. The triple-chain forms of clusters B and B remain unchanged upon sequential addition of P atoms, showcasing a perfect isolobal substitution of {P} with {CH}. Similarities in the number of delocalized electrons are observed between pure and doped boron clusters, alongside the subsequent substitution of {P} with {CH}.

An Analytical View on the Use of Flucloxacillin for Outpatient Parenteral Antimicrobial Therapy.

Although the addition of buffers provides improved stability to flucloxacillin (FLU) solutions, unbuffered solutions are often preferred in clinical practice. The first purpose of this study was to investigate whether a 50 mg/mL solution of FLU in normal saline is stable for 24 h at 33 °C so that it can be applied for outpatient parenteral antimicrobial therapy (OPAT) using portable elastomeric infusion pumps (PEIPs). When the PEIPs were stored in an oven at 33 °C and deflated over 24 h, the volume of the collected solution, pH, and FLU concentration were checked every 4 h.

Enhanced Care for Pediatric Patients With Generalized Lichen Planus: Diagnosis and Treatment Tips.

The rarity of generalized lichen planus (LP) in children often leads to misdiagnosis or delayed treatment, impacting the patient's quality of life. We describe the utility of a punch biopsy to confirm the diagnosis of LP in a 7-year-old girl. The inclusion of an intramuscular corticosteroid injection in the treatment plan offered prompt symptom relief.

d-[5-C]-Glutamine Positron Emission Tomography Imaging for Diagnosis and Therapeutic Monitoring of Orthopedic Implant Infections.

Orthopedic implant infections (OIIs) present diagnostic and therapeutic challenges, owing to the lack of methods to distinguish between active infection and sterile inflammation. To address this unmet need, d-amino-acid-based radiotracers with unique metabolic profiles in microorganisms have emerged as a novel class of infection-specific imaging agents. Given the pivotal role of d-glutamine in bacterial biofilm formation and virulence, herein, we explored the potential of positron emission tomography (PET) imaging with d-[5-C]-Glutamine (d-[5-C]-Gln) for early detection and treatment monitoring of OIIs.

Current Overview of the Biology and Pharmacology in Sugen/Hypoxia-Induced Pulmonary Hypertension in Rats.

The Sugen 5416/hypoxia (Su/Hx) rat model of pulmonary arterial hypertension (PAH) demonstrates most of the distinguishing features of PAH in humans, including increased wall thickness and obstruction of the small pulmonary arteries along with plexiform lesion formation. Recently, significant advancement has been made describing the epidemiology, genomics, biochemistry, physiology, and pharmacology in Su/Hx challenge in rats. For example, there are differences in the overall reactivity to Su/Hx challenge in different rat strains and only female rats respond to estrogen treatments.

Discovery of a nasal spray steroid, tixocortol, as an inhibitor of SARS-CoV-2 main protease and viral replication.

Coronaviruses rely on the viral-encoded chymotrypsin-like main protease (M or 3CL) for replication and assembly. Our previous research on M of SARS-CoV-2 identified cysteine 300 (Cys300) as a potential allosteric site of M inhibition. Here, we identified tixocortol (TX) as a covalent modifier of Cys300 which inhibits M activity as well as in a cell-based M expression assay.

Mast Cells Mediate Acute Inflammatory Responses After Glenoid Labral Tears and Can Be Inhibited With Cromolyn in a Rat Model.

Background: Injuries to the glenoid labrum have been recognized as a source of joint pain and discomfort, which may be associated with the inflammatory responses that lead to the deterioration of labral tissue. However, it is unclear whether the torn labrum prompts mast cell (MC) activation, resulting in synovial inflammatory responses that lead to labral tissue degeneration.

Purpose: To determine the potential influence of activated MC on synovial inflammatory responses and subsequent labral tissue degeneration and shoulder function deterioration in a rat model by monitoring MC behavior and sequential inflammatory responses within the synovial tissue and labral tissue after injury, suture repair, and MC stabilizer administration.
