Synthesis of AgNPs has been of considerable interest during the past few decades as they exhibit better antimicrobial activity compared to metallic silver [8, 9].” • “The high surface to volume ratio of AgNP enables the nanoparticles to better fuse with the bacterial cell membranes [11]. The above should be written as “The high surface to volume ratio of AgNP enables the nanoparticles to better fuse with the bacterial cell membranes [11, 12]. Pages 191–192 Afatinib • “Surfactants have been widely used to modify the surface chemistry of colloidal particles [13, 14] and to impart extra

stability to dispersions [15–17]. In addition, they are known for tuning colloidal interactions [18, 19]. The interactions of ionic surfactants, their micellar solutions or mesophases with charge-stabilized colloidal particles are too strong, leaving limited regions of miscibility [20–23] and these problems may be overcome when nonionic surfactants are used. Therefore, in this context, the role of nonionic surfactants is important. The small colloidal particles can be embedded

HCS assay in solutions of nonionic surfactant, even fairly concentrated ones [22, 24–26] and such nonionic surfactants are relatively insensitive to ionic strength and pH which provide sterically stabilizing colloidal particles through adsorption [27–30]. The above should be written as “Surfactants are well known to alter the surface chemistry of colloidal particles [13, 14] and to provide added stability to the dispersions [15–17]. In addition, they are known for tuning colloidal interactions [18, 19]. The interactions of ionic surfactants, their micellar solutions or mesophases with charge-stabilized colloidal particles result in partial miscibility [20–23] and these problems may be overcome when nonionic surfactants are used [15]. Therefore, in this case, the role of nonionic surfactants is essential. The small colloidal particles can be entrapped in concentrated solutions of nonionic surfactants

[22, 24–26], which are insensitive to ionic strength and pH, leading to sterically stabilized colloidal particles via adsorption [15, 27–30]. “
“Practices in the perinatal field change constantly as mothers’ characteristics evolve, scientific knowledge improves, and both clinical practice guidelines very and the organisation of care are modified. In such a setting, it is important to have reliable perinatal data, regularly updated, available at the national level, to monitor health trends, guide prevention policies and assess medical practices. The national perinatal surveys were designed to meet these needs. They are based on the principle of a collection of information about health status and perinatal care from a representative sample of births. Three surveys were previously conducted and reported, in 1995, 1998 and 2003 [1].
