targeting properties This report describes the synthesis and structural characterization of the indium complex of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid mono(p-aminoanilide) (DOTA-AA), a model compound for 111In-labeled DOTA-biomolecule conjugates. In(DOTA-AA) was prepared by reacting DOTA-AA with 1 equiv of InCl3 in 0.5 M ammonium acetate buffer (pH ∼ 6). It was characterized by spectroscopic methods (IR, ES-MS, and 1H NMR), elemental analysis, and X-ray crystallography. For comparison

University, College Station, Texas, USA Radiation hazards in outer space present an enormous challenge for the biological safety of astronauts. A deleterious effect of radiation is the production of reactive oxygen species, which result in damage to biomolecules (e.g., lipid, protein, amino acids, and DNA). Understanding free radical biology is necessary for designing an optimal nutritional countermeasure against space radiation–induced cytotoxicity. Free radicals (e.g., superoxide, nitric oxide, and hydroxyl

what changes in nitrogen levels as a result of human activity means to local and global ecosystems. Introduction Nitrogen is one of the primary nutrients critical for the survival of all living organisms. It is a necessary component of many biomolecules, including proteins, DNA, and chlorophyll. Although nitrogen is very abundant in the atmosphere as dinitrogen gas (N2), it is largely inaccessible in this form to most organisms, making nitrogen a scarce resource and often limiting primary productivity

Diabetes [Name of Author] [Name of Institution] Question 1 The key area which must be considered for conducting initial assessments for Jazminder is the identification of hyperglycemia. It is recommended that her glucose concentrations for plasma must be measured. A two-hour post load glucose test or an FPG test is recommended by the International Diabetes Federation (IDF) and WHO for patient susceptible of developing diabetes. Assessment of diabetes is also done through HbA1c in which the

CHEMICAL CONVERSIONS Acylation Acylation (rarely, but more formally: alkanoylation) is the process of adding an acyl group to a compound. The compound providing the acyl group is called the acylating agent. These are used to form aryl ketones. Because they form a strong electrophile when treated with some metal catalysts, acyl halides are commonly used as acylating agents. For example, Friedel-Crafts acylation uses acetyl chloride (ethanoyl chloride), CH3COCl, as the agent and aluminum chloride

conversion to chemical energy of living cells. The other pigments also absorb light energy, but it is transferred to the chlorophyll for conversion to chemical energy. Biochemists have developed a variety of methods for the purification and analysis of biomolecules. Several of these techniques will be used in this laboratory exercise in order to isolate and study the photosynthetic pigments, chlorophyll a, chlorophyll b, and carotenoids. These include paper chromatography and spectrophotometry. Paper chromatography

CHEMISTRY CHEMISTRY (CLASSES XI–XII) Rationale Higher Secondary Stage is the most crucial stage of school education because at this stage specialised discipline based, content oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry with a purpose of mostly for pursuing their career in basic sciences or professional courses like medicines, engineering, technology and studying courses in applied areas of science and technology at tertiary
