BACKGROUND AND AIM: One of the unmet needs in subjects with metabolic risks is the prediction of metabolic liver disease by noninvasive tests. The construction of performant tests is dependent on the appropriateness of the histological reference definition. The aim of this study was to analyze the limitations of similar European (Fatty Liver Inhibition of Progression) and USA (Clinical-Research-Network) standard definitions and their impact on the construction of tests. METHODS: We hypothesized that a simpler histological definition of non-alcoholo steato-hepatitis (NASH), which does not require the presence of steatosis and the presence of both lobular inflammation and ballooning, should improve the concordance rates with previously validated blood tests...

BACKGROUND: Treatment of congenital pulmonary airway malformations (CPAMs) is generally surgical resection; however, there is controversy regarding the optimal timing of surgical intervention, especially in asymptomatic patients. STUDY DESIGN: Using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric Participant Use Files from 2012-2015, children who underwent lung resection for CPAM were identified. Outcomes in children who underwent lung resection during the neonatal period were compared with those who underwent resection beyond the neonatal period, but during the first year of life (non-neonates)...

BACKGROUND: Pediatric surgeons frequently offer prenatal consultation for congenital pulmonary airway malformation (CPAM) and congenital diaphragmatic hernia (CDH); however, there is no evidence-based consensus to guide prenatal decision making and counseling for these conditions. Eliciting feedback from experts is integral to defining best practice regarding prenatal counseling and intervention. METHODS: A Delphi consensus process was undertaken using a panel of pediatric surgeons identified as experts in fetal therapy to address current limitations...

Asymptomatic cystic lung lesions-congenital pulmonary airway malformations (CPAMs), sequestrations, and bronchogenic cysts-are commonly diagnosed prenatally. Indications to resect are to eliminate risk of malignancy or infection. CPAMs consist of a spectrum of malformations, with type 1 historically considered the most common. Mucinous cell clusters, seen almost exclusively in type 1, are premalignant lesions at risk for progression to mucinous adenocarcinoma. We reviewed and classified 2.5 years of consecutive, prenatally diagnosed lesions as extralobar sequestration, intralobar sequestration, type 1 CPAM, type 2 CPAM/bronchial atresia, or "other" to determine the distribution of lesion types and risk of malignancy...

Previous investigations showed that cationic polyacrylamide (cPAM), a flocculant widely used in wastewater pretreatment and waste activated sludge dewatering, deteriorated methane production during anaerobic digestion of sludge. However, details of how cPAM affects methane production are poorly understood, hindering deep control of sludge anaerobic digestion systems. In this study, the mechanisms of cPAM affecting sludge anaerobic digestion were investigated in batch and long-term tests using either real sludge or synthetic wastewaters as the digestion substrates...

INTRODUCTION: A congenital pulmonary airway malformation (CPAM) type III may become large enough to cause hydrops fetalis. In such circumstances, the fetus can be treated with open fetal resection, maternal betamethasone administration, or percutaneous sclerotherapy. CASE REPORT: A 24 week gestation fetus with a CPAM type III was treated by percutaneous sclerotherapy using ethanolamine oleate (EO). The EO inadvertently entered the left atrium and ventricle with subsequent fetal bradycardia and demise...

In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated. The results show that the poor water quality with high concentrations of oil, suspended solids (SS) and polymer greatly increases the oily wastewater emulsion stability and the difficulty of the flocculation treatment process...

PURPOSE: Resection of congenital pulmonary airway malformations (CPAMs) is often performed to reduce the risk of recurrent infection and malignant transformation. However, there is substantial variation in the timing of resection. This study was performed to determine the association of age and weight on outcomes following elective resection of CPAMs. METHODS: The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database from 2012 to 2014 was queried for infants undergoing elective resection of a CPAM...

INTRODUCTION: Congenital pulmonary airway malformation (CPAM) is a major indication of lobectomy in children. Early lobectomy had been proposed for the advantage of compensatory lung growth. Despite the increasing use of thoracoscopic lobectomy its effect on postoperative lung function was still not well established in the literature. This study was therefore performed to study the result of postoperative pulmonary function test (PFT) on a medium term basis. MATERIALS AND METHODS: All patients who underwent thoracoscopic lobectomy for CPAM between 2006 and 2010 were recruited into the study...

Chronic hepatitis B virus (HBV) infection is difficult to cure, due to the presence of covalently-closed-circular DNA and virus-mediated blunting of host immune response. Existing therapies with nucleos(t)ide analogue or pegylated-interferon are not sufficient to achieve a high rate of HBV surface antigen seroclearance, a more desirable treatment outcome. Novel therapeutic agents targeting alternative viral replication steps are being developed. In this review, we will discuss the hepatitis B core antigen (HBcAg) as a therapeutic target...

Congenital pulmonary airway malformations or CPAM are rare developmental lung malformations, leading to cystic and/or adenomatous pulmonary areas. Nowadays, CPAM are diagnosed prenatally, improving the prenatal and immediate postnatal care and ultimately the knowledge on CPAM pathophysiology. CPAM natural evolution can lead to infections or malignancies, whose exact prevalence is still difficult to assess. The aim of this "state-of-the-art" review is to cover the recently published literature on CPAM management whether the pulmonary lesion was detected during pregnancy or after birth, the current indications of surgery or surveillance and finally its potential evolution to pleuro-pulmonary blastoma...

The suspended solids in wastewater from Rekabak oilfield, Kazakhstan, were characterized and treated with flocculants to enhance settling. The wastewater contained a high concentration of total dissolved solids and calcium ion. Scanning electron microscopy and energy dispersive X-ray analyses showed that suspended solids were mainly composed of corrosion products (iron oxides) and silicon dioxide particles. Also, much salt deposition from wastewater caused a large increase in the suspended solids value. The settling of solid particles in wastewater was investigated by turbidity decrease within 60 min...

Aim  We report a case of congenital pulmonary airway malformation (CPAM) with hydrops in which the fetus underwent thoracoamniotic shunting. Case Report  A 40-year-old (G1P1) woman was diagnosed with a macrocystic CPAM. Thoracoamniotic shunting was performed at 19 weeks of gestation but not well drained and was successfully performed again at 23 weeks. However, the CPAM volume ratio, abdominal circumference, and amniotic fluid index started increasing from 28 weeks and hydrops worsened. The insufficient shunting and the fetal cardiac failure had to be considered...

Strong water trapping ability of polyelectrolyte flocculated sludge and high compressibility of sludge filter cake greatly hindered the further improvement of sludge dewaterability. Ultrasound (US) was used to strip the water from the sludge flocs through sludge disintegration, traditional cationic polyacrylamide (CPAM) was applied to reconstruct the sludge aggregates through flocculation, and rice husk (RH) was utilized to improve the permeability of sludge filter cake as skeleton builders in this paper. The feasibility of combined US-CPAM-RH sludge conditioning was demonstrated, and single and co-conditioning processes were compared to explore the synergetic effect and mechanisms of US-CPAM-RH sludge conditioning...

Hepatitis B virus (HBV) core protein assembles viral pre-genomic (pg) RNA and DNA polymerase into nucleocapsids for reverse transcriptional DNA replication to take place. Several chemotypes of small molecules, including heteroaryldihydropyrimidines (HAPs) and sulfamoylbenzamides (SBAs), have been discovered to allosterically modulate core protein structure and consequentially alter the kinetics and pathway of core protein assembly, resulting in formation of irregularly-shaped core protein aggregates or "empty" capsids devoid of pre-genomic RNA and viral DNA polymerase...

Controlling nanoparticles (NPs) aggregation in cellulose/NPs composites allows to optimise NPs driven properties and their applications. Polyelectrolytes are used to control NPs aggregation and their retention within the fibrous matrix. Here, we aim at evaluating how a polyelectrolyte (Cationic Polyacrylamide; CPAM, molecular weight: 13MDa, charge: 50%, Radius of gyration: 30-36nm) adsorbs and re-conforms onto the surface of silica(SiO2) NPs differing in diameter (8, 22 and 74nm) and to investigate the respective NPs aggregation in cellulose matrices...
