AIM OF THE STUDY: Recommendation of early pulmonary resection in asymptomatic congenital pulmonary airway malformations (CPAMs) is based on the presumed compensatory lung growth during the first months of life. Our aim is to analyze the long-term pulmonary function after lobectomy before and after one year of age using spirometry. METHODS: We performed a retrospective review of children who underwent pulmonary lobectomy for CPAM between 2001 and 2016. Patients who were old enough (>5 years) to carry out a spirometry were included in the study and were divided into 2 groups (surgery before or after 12 months of age)...

Saturated fatty acids are the most abundant fatty acids in the brain, however, there has been some debate regarding the ability of intact dietary saturated fatty acids to be incorporated into the brain. In the present study, we use compound specific isotope analysis to measure the natural abundance carbon isotopic signature of brain, liver, and blood palmitic acid (PAM) and compare it to the dietary PAM and sugar isotopic signatures to calculate the relative contribution of both the incorporation of intact and endogenously synthesized PAM to these pools...

FeCl3 , quick lime, and cationic polyacrylamide (CPAM) were used for excess sludge conditioning from wastewater treatment plant (WWTP) and the dewatering performance by different chemical conditioners was investigated. Experimental results showed that FeCl3 could make small and concentrated sludge particles. Furthermore, new mineral phase structures for building a dewatering framework were obtained by the addition of quick lime, and the coagulation capacity was enhanced by the formation of colloid hydroxyl polymer, which was induced due to the alkaline environment...

Congenital pulmonary airway malformation (CPAM) is a developmental malformation of the lower respiratory tract. We report the case of a male newborn diagnosed with cystic lung disease during prenatal ultrasound. A cesarean section was performed at the 32nd gestational week because of premature rupture of the membranes, and soon after the delivery the newborn developed respiratory failure and died. The aim of this study is to report an autopsy case because of its rarity, and to briefly discuss the CPAM subtypes and differential diagnosis of cystic lung diseases of childhood...

BACKGROUND AND OBJECTIVE:  Congenital pulmonary airway malformation (CPAM) is a group of rare congenital malformations of the lung and airways. Lung ultrasound (LU) is increasingly used to diagnose neonatal respiratory diseases since it is quick, easy to learn, and radiation-free, but no formal data exist for congenital lung malformations. We aimed to describe LU findings in CPAM neonates needing neonatal intensive care unit (NICU) admission and to compare them with a control population...

In this study, the ultrasonic (US)-initiated template copolymerization was employed to synthesize a novel cationic polyacrylamide (CPAM) characterized by a microblock structure using dimethyldiallylammonium chloride (DMDAAC) and acrylamide (AM) as monomers, and sodium polyacrylate (NaPAA) as template. The polymers structure property was analyzed by Fourier transform infrared spectroscopy (FT-IR), 1 H nuclear magnetic resonance spectroscopy (1 H NMR) and thermogravimetric analysis (TGA). The results showed that a novel cationic microblock structure was successfully synthesized in the template copolymer of DMDAAC and AM (TPADM)...

Hepatitis B virus (HBV) core protein consists of N-terminal assembly domain and C-terminal domain (CTD) with seven conserved serines or threonine that are dynamically phosphorylated/dephosphorylated during the viral replication cycle. Sulfamoylbenzaminde derivatives are small molecular core protein allosteric modulators (CpAMs) that bind to the HAP pocket between the core protein dimer-dimer interfaces. CpAM binding alters the kinetics and pathway of capsid assembly and can result in the formation of morphologically "normal" capsids devoid of viral pregenomic (pg) RNA and DNA polymerase...

Prior to mechanical dewatering, sludge conditioning is indispensable to reduce the difficulty of sludge treatment and disposal. The effect of bioacidification conditioning driven by Acidithiobacillus ferrooxidans LX5 on the dewatering rate and extent of sewage sludge during compression dewatering process was investigated in this study. The results showed that the bioacidification of sludge driven by A. ferrooxidans LX5 simultaneously improved both the sludge dewatering rate and extent, which was not attained by physical/chemical conditioning approaches, including ultrasonication, microwave, freezing/thawing, or by adding the chemical conditioner cationic polyacrylamide (CPAM)...

PURPOSE: Cervical cancer screening reduces the incidence and specific mortality rate of cervical neoplasms. In most cases screening by means of Pap smears is performed in France by gynecologists. The primary objective of this study was to confirm whether the participation rate is increased when general practitioners (GPs) carry out the smears themselves. The secondary objective was to evaluate other independent characteristics of GPs predicting participation rates in women. METHODS: The population of 347 GPs, including their relevant characteristics and their 90,094 female patients eligible for screening over 2 years (2013-2014), was derived from the SIAM claim database of the Flanders Healthcare Insurance Fund (CPAM)...

Cationic acrylamide-based polyelectrolytes (cPAM) are widely used in industry. They can be designed for optimal performance in a specific application, but this opportunity means the environmental safety of all different alternatives needs to be addressed. Both the inclusion of environmental toxicity as a design variable and the establishment of relationships between structure and ecotoxicity are thus current challenges. The aim of this study was to assess whether structural variables such as molecular weight, charge density and the integrative intrinsic viscosity parameter can be used to predict the environmental safety of cPAMs, as well as if these relationships are stable when the biological models change...

Evidence-based parenting support programs (EBPS) based on social learning and cognitive behavioral principles are effective in reducing conduct-related problems in a diverse range of cultural contexts. However, much less is known about their effects with indigenous families. A Collaborative Participation Adaptation Model (CPAM) was used to culturally adapt a low-intensity, two-session group variant of the Triple P-Positive Parenting Program for Māori parents of young children in New Zealand. CPAM involved collaborating closely with Māori tribal elders, practitioners as end-users, and parents as consumers through a participatory process to identify content and delivery process used in Triple P that would ensure that traditional Māori cultural values were incorporated...

Dissolved organic nitrogen (DON) is an important component of aquatic environment of which amount impacts water quality. Thus, removal of DON has attracted wide attention. At present, it is difficult for common coagulation to remove DON from the aquatic environment. The cationic polymers can help to improve the removal efficiency of DON to some extent, but the underlying mechanism of the ascension is not clear. In order to grasp its removal behavior and further improve the removal efficiency of DON in the future, we evaluated the effect of a hybridized coagulant of polyacrylamide with iron-based coagulant on removal of aquatic DON...
