Class activation

Out of experiences like this, we developed continuing relationships with the teachers and students at our pilot schools. We conducted in-class activities to complement major curriculum topics every 3 weeks or so. In addition, we assisted in other ways, such as helping elementary school teachers understand science content and working with science fairs. 

The marine environment clearly holds an enormous amount of potential to provide new leads for the development of treatments for infectious disease and antimalarial compounds in particular. The identification of new structural classes active against the malaria parasite will provide new mechanisms of action and better treatments for resistant strains. Since most malaria-infected regions also possess coastal areas rich in diverse marine invertebrate life, marine natural products provide an opportunity for these areas to utilize endemic resources to combat this devastating disease. 

The identification of new natural product structural classes active against insects will attack the pest-resistance problem and provide environmentally safer insecticides. The marine environment, with its chemical diversity, clearly holds an enormous potential to provide leads for the development of insecticidal agents. Many marine-derived structural classes have not yet been examined for their insecticidal activity. Further SAR studies of these marine natural products could lead to new and more selective insecticidal agents. 

Hands-On Chemistry activities that allow students to experience chemistry outside a formal laboratory setting. These activities can be performed using common household ingredients and equipment. Most chapters have two or three Hands-On features, which lend themselves well to distance learning or to in-class activities. 

The course ended with a mock trial. Students volunteered to be lawyers and expert witnesses. The students were divided into two teams, the defense and the prosecution, with specific roles to present evidence discovered in each class activity. Each student was required to turn in a written document summarizing his or her testimony supported by research. Furthermore, they presented the evidence, developed and defended their ideas, showed an understanding of the limitations of scientific data and its applicability to law and to appreciate the importance of integrating data analysis with communication skills. 

Moxifloxacin is an 8-methoxyquinolone with enhanced potency against important Gram-positive pathogens, notably Streptococcus pneumoniae (penicillin-resistant and penicillin-susceptible strains), and class activity against Gram-negative bacteria. Its activity is not affected by beta-lactamases. Moxifloxacin may therefore represent a promising alternative for treatment of respiratory tract infections (1). 

These include amitraz (110), prepared from 54, a member of the form amidine class, active against mites and ticks, that have replaced organophosphorus compounds. Notably, amitraz is active against newer strains of pyrethroid-resistant ticks. The reaction of diphenylamine (8) with sulfur in the presence of iodine as catalyst yields the anthelmintic (worming agent) phenothiazone (phenothiazine) (111) (Scheme 24). It is too toxic for human use, though it is an intermediate in the production of antipsychotic drugs. 

Prom the Process Ontology (module WorkProcessDocumentation), the following concepts are shown The class Activity represents a single step of a work process. Activities are performed by Actors, often with the help of some (software) Tool. A connection to the Document Model is established via the Information class. Information can be both input or output of an Activity. 

Many functions of protein kinase C in signaling pathways are closely linked with the membrane association of the enzyme. Signal-dependent association of PKC with the cell membrane is therefore another major regulatory aspect of this enzyme class. Activation of protein kinase C, initiated by addition of phorbol esters, for example, is associated with a redistribution of the enzyme from the cytosol to the membrane.

The course makes extensive use of in-class activities that involve computer modeling, visualizations, simulations, and experiments. Activities are done in small groups with questions that focus the activities and gauge student learning. Students also read and discuss Hazen s book in class and conduct research for a paper and in-class presentation. Some of these activities are described below. 

Coenzymes are complex nonprotein organic molecules that participate in catalysis by providing functional groups, much like the amino acid side chains. In the human, they are usually (but not always) synthesized from vitamins. Each coenzyme is involved in catalyzing a specific type of reaction for a class of substrates with certain structural features. Coenzymes can be divided into two general classes activation-transfer coenzymes and oxidation-reduction coenzymes.
