Phytoassisted synthesis of CuO and Ag-CuO nanocomposite, characterization, chemical sensing of ammonia, degradation of methylene blue.

The elimination of hazardous industrial pollutants from aqueous solutions is an emerging area of scientific research and a worldwide problem. An efficient catalyst, Ag-CuO was synthesized for the degradation of methylene blue, the chemical sensing of ammonia. A simple novel synthetic method was reported in which new plant material Capparis decidua was used for the reduction and stabilization of the synthesized nanocatalyst.

Synthesis, crystal and electronic structures, linear and nonlinear optical properties, and photocurrent response of oxyhalides CeHaVIO (Ha = Cl, Br; VI = Mo, W).

Four heteroanionic oxyhalides, CeClMoO, CeBrMoO, CeClWO, and CeBrWO, have been studied as multifunctional materials, which show a combination of good second harmonic generation (SHG) response and photocurrent signals. Millimeter-sized CeHaVIO (Ha = Cl, Br; VI = Mo, W) crystals were grown by halide salt flux. The crystal structure of CeHaVIO crystals was accurately determined by single-crystal X-ray diffraction.

CT-Guided vs. Navigational Bronchoscopic Biopsies for Solitary Pulmonary Nodules: A Single-Institution Retrospective Comparison.

Objective: Lung cancer is the second most common cause of death by cancer. Multiple modalities can be used to obtain a tissue sample from a pulmonary nodule. We aimed to compare the yield and adverse events related to transthoracic needle aspiration (TTNA) and Electromagnetic Navigation Biopsy (ENB) at our institution.

Pig-to-human heart xenotransplantation in two recently deceased human recipients.

Genetically modified xenografts are one of the most promising solutions to the discrepancy between the numbers of available human organs for transplantation and potential recipients. To date, a porcine heart has been implanted into only one human recipient. Here, using 10-gene-edited pigs, we transplanted porcine hearts into two brain-dead human recipients and monitored xenograft function, hemodynamics and systemic responses over the course of 66 hours.

Thoracoabdominal normothermic regional perfusion in donation after circulatory death does not restore brain blood flow.

Use of thoracoabdominal normothermic regional perfusion (TA-NRP) during donation after circulatory death (DCD) is an important advance in organ donation. Prior to establishing TA-NRP, the brachiocephalic, left carotid, and left subclavian arteries are ligated, thereby eliminating anterograde brain blood flow via the carotid and vertebral arteries. While theoretical concerns have been voiced that TA-NRP after DCD may restore brain blood flow via collaterals, there have been no studies to confirm or refute this possibility.

Acute Respiratory Distress Syndrome; A Review of Recent Updates and a Glance into the Future.

Acute respiratory distress syndrome (ARDS) is a rapidly progressive form of respiratory failure that accounts for 10% of admissions to the ICU and is associated with approximately 40% mortality in severe cases. Despite significant mortality and healthcare burden, the mainstay of management remains supportive care. The recent pandemic of SARS-CoV-2 has re-ignited a worldwide interest in exploring the pathophysiology of ARDS, looking for innovative ideas to treat this disease.

Donation after circulatory death heart transplantation using normothermic regional perfusion:The NYU Protocol.

Objective: This study aimed to evaluate the impact of cardiopulmonary bypass for thoraco-abdominal normothermic regional perfusion on the metabolic milieu of donation after cardiac death organ donors before transplantation.

Methods: Local donation after cardiac death donor offers are assessed for suitability and willingness to participate. Withdrawal of life-sustaining therapy is performed in the operating room.

Right heart thrombus in transit: Raising bar in the management of cardiac arrest.

Right heart thrombus represents medical emergency as it is associated with acute pulmonary embolism. Right heart thrombus can manifest acutely in a dramatic fashion as cardiac arrest. Bedside echocardiography is a key to rapid diagnosis and allow early intervention.

Endobronchial mucormycosis: A rare clinical entity diagnosed by endobronchial cryobiopsy.

Mucormycosis is a rare fungal infection caused by fungi of the order Mucorales. The rhino-cerebral form of mucormycosis is most commonly seen in patients with diabetes mellitus, whereas pulmonary mucormycosis is a rare manifestation in patients with hematological malignancy and transplant recipients. We report a case of a 40-year-old male, with history of poorly controlled diabetes, who presented to the emergency room with a one-week history of hemoptysis.

Revisiting thiophosphate PbPS: a multifunctional material combining a nonlinear optical response and photocurrent response.

PbPS was structurally characterized three decades ago with a second harmonic generation response. In this work, PbPS was revisited to investigate its electronic structure DFT calculations and optical properties by UV-vis measurements, second harmonic generation tests, laser damage threshold tests, and photocurrent measurements. PbPS is constructed by [PbS] polyhedra and [PS] tetrahedra, which was supported by crystal orbital Hamilton population (COHP) calculations.

A case of drug-induced parkinsonism and tardive akathisia with e1143g polymerase γ mutation-innocent bystander or a culprit?

Background And Aim: Polymerase γ (POLG) is a protein that plays a pivotal role in the replication of the mitochondrial genome. POLG-related disorders constitute a sequence of overlying phenotypes that can present from early infancy to late adulthood. Parkinsonism is the most common movement disorder associated with POLG mutation.

Invasive Aortic Valve Endocarditis: Clinical and Tissue Findings From a Prospective Investigation.

Background: Advanced aortic valve infective endocarditis (IE) with progression and destruction beyond the valve cusps-invasive IE-is incompletely characterized. This study aimed to characterize further the invasive disease extent, location, and stage and correlate macroscopic operative findings with microscopic disease patterns and progression.

Methods: A total of 43 patients with invasive aortic valve IE were prospectively enrolled from August 2017 to July 2018.

Minimally Invasive Off-Pump Technique for Temporary Left Ventricular Support.

Use of short-term mechanical circulatory support (MCS) for cardiogenic shock has rapidly increased. Most common initial MCS strategies entail institution of peripheral extracorporeal membrane oxygenation (ECMO) or temporary ventricular assist devices. For patients with anatomically small peripheral arteries or insufficient circulatory support, sternotomy and central cannulation techniques may be necessary.

Development of a hybrid framework for inventory leanness in Technical Services Organizations.

Inherent uncertainties in demand and supply make it problematic for supply chains to accomplish optimum inventory replenishment, resulting in loss of sales or keeping excessive inventories. To cope with erratic demands, organizations have to maintain excessive inventory levels, sometimes taking up to one-third of an organization's annual budget. The two most pressing concerns to handle in inventory management are: how much to order and when to order.

Patterns of Hepatocellular Carcinoma After Direct Antiviral Agents and Pegylated-Interferon Therapy.

Introduction:  The impact of direct-acting antiviral agents (DAAs) on the development of hepatocellular carcinoma (HCC) is controversial and a part of the scientific community believes it as a biased interpretation of data. Many studies have reported an aggressive pattern of HCC after DAA use. In this study, we attempted to assess the changes in the pattern of HCC after treatment with DAAs or PI (PEG, pegylated-interferon).

COVID-19 in recent heart transplant recipients: Clinicopathologic features and early outcomes.

Background: The impact of COVID-19 on heart transplant (HTx) recipients remains unclear, particularly in the early post-transplant period.

Methods: We share novel insights from our experience in five HTx patients with COVID-19 (three within 2 months post-transplant) from our institution at the epicenter of the pandemic.

Results: All five exhibited moderate (requiring hospitalization, n = 3) or severe (requiring ICU and/or mechanical ventilation, n = 2) illness.

Cardiac hypertrophic risk markers of left ventricle and left atrium in chronic heart failure due to aortic and mitral valve disease.

Background: Chronic valvular heart disease leads to systolic dysfunction and left atrial enlargement that ultimately results in heart failure.

Purpose: To investigate prognostic importance of Echocardiography and plasma natriuretic peptide levels that increase as a compensatory response and can be used as predictive markers for cardiac hypertrophy.

Material And Methods: The patients were divided into three groups: 51 with left ventricle hypertrophy due to aortic valve disease; 126 with left atrial enlargement due to mitral valve dysfunction; and 76 with both conditions.

Do they really coexist? An empirical analysis of a conjoint implementation of Quality Management System and High Performance Work System on organizational effectiveness.

Over the past few decades, Quality Management System (QMS) and High Performance Work System (HPWS) have emerged as key concepts to enhance organizational effectiveness. All over the globe, majority of contemporary manufacturing and services organizations have applied at least one of these development strategies or even both. This study proposes an integrated framework of QMS and HPWS and empirically investigates the relationship between QMS and HPWS practices and their direct and indirect effects on organizational effectiveness using structural equation modelling (SEM).
