[Q]: The first year after birth is called infancy. Infancy is a period when the baby grows very fast. During infancy, the baby doubles in length and triples in weight. Other important changes also happen during infancy: The babys teeth start to come in, usually at about six months of age ( Figure 1.1). The baby starts smiling, paying attention to other people, and grabbing toys. The baby begins making babbling sounds. By the end of the first year, the baby is starting to say a few words, such as mama and dada. The baby learns to sit, crawl, and stand. By the end of the first year, the baby may be starting to walk. Childhood begins after the babys first birthday and continues until the teen years. Between one and three years of age, a child is called a toddler. During the toddler stage, growth is still fast, but not as fast as it was during infancy. A toddler learns many new words. The child even starts putting together words in simple sentences. Motor skills also develop quickly during this stage. By age three, most children can run and climb steps. They can hold crayons and scribble with them. They can also feed themselves and use the toilet. From age three until the teens, growth is slower. The body also changes shape. The arms and legs get longer compared to the trunk. Children continue to develop new motor skills. For example, many young children learn how to ride a tricycle and then a bicycle. Most also learn how to play games and sports ( Figure 1.2). By age six, children start losing their baby teeth. Their permanent teeth begin coming in to replace them. They also start school and learn how to read and write. They develop friendships and become less dependent on their parents. There are numerous milestones that occur during the first few years of childhood. These include the use of language, walking and running, understanding simple concepts, pretend play, the development of fine motor skills, the development of independence, Children develop better motor skills as they get older. having temper tantrums, demonstrating separation anxiety, becoming fully potty-trained, showing natural curiosity.

[Q]: The War of the Spanish Succession was a European conflict of the early 18th century, triggered by the death of the childless Charles II of Spain in November 1700. His closest heirs were members of the Austrian Habsburg and French Bourbon families; acquisition of an undivided Spanish Empire or Monarchy by either threatened the European balance of power. Charles left his throne to Louis XIV's grandson Philip who was proclaimed King of Spain on 16 November 1700. Disputes over the separation of the Spanish and French crowns, division of territories and commercial rights led to war in 1701 between the Bourbons of France and Spain and the Grand Alliance, whose candidate was Archduke Charles, younger son of Habsburg Emperor Leopold. By 1710, fighting was deadlocked; Allied victories in Italy and the Low Countries had driven the French back to their borders but they could not achieve a decisive breakthrough while Philip was secure in Spain. When Archduke Charles succeeded his brother Joseph I as Emperor in 1711, Britain effectively withdrew, forcing its Allies to make peace and leading to the 1713 Treaty of Utrecht, followed in 1714 with Rastatt and Baden. Philip was confirmed as King of Spain and renounced the French throne; Spain retained the bulk of its pre-war territories outside Europe with their European territories divided between Austria, Britain and Savoy. Longer term impacts included Britain's emergence as the leading maritime and commercial power, the beginning of the decline of the Dutch Republic, the creation of a centralised Spanish state and the acceleration of the break-up of the Holy Roman Empire.
[A]: Who was Emperor first, Archduke Charles or his brother Joseph I?


[Q]: Nox activator 1 (NoxA1) is a homologue of p67(phox) that acts in conjunction with Nox organizer 1 (NoxO1) to regulate reactive oxygen species (ROS) production by the NADPH oxidase Nox1. The phosphorylation of cytosolic regulatory components by multiple kinases plays important roles in assembly and activity of the phagocyte NADPH oxidase (Nox2) system, but little is known about regulation by phosphorylation in the Nox1 system. Here we identify Ser(172) and Ser(461) of NoxA1 as phosphorylation sites for protein kinase A (PKA). A consequence of this phosphorylation was the enhancement of NoxA1 complex formation with 14-3-3 proteins. Using both a transfected human embryonic kidney 293 cell Nox1 model system and endogenous Nox1 in colon cell lines, we showed that the elevation of cAMP inhibits, whereas the inhibition of PKA enhances, Nox1-dependent ROS production through effects on NoxA1. Inhibition of Nox1 activity was intensified by the availability of 14-3-3zeta protein, and this regulatory interaction was dependent on PKA-phosphorylatable sites at Ser(172) and Ser(461) in NoxA1. We showed that phosphorylation and 14-3-3 binding induce the dissociation of NoxA1 from the Nox1 complex at the plasma membrane, suggesting a mechanism for the inhibitory effect on Nox1 activity. Our data establish that PKA-phosphorylated NoxA1 is a new binding partner of 14-3-3 protein(s) and that this forms the basis of a novel mechanism regulating the formation of ROS by Nox1 and, potentially, other NoxA1-regulated Nox family members.
