Hypocretins : Integrators of Physiological Signals

The first report that rapid eye movements occur in sleep in humans was published in 1953. The research journey from this point to the realization that sleep consists of two entirely independent states of being (eventually labeled REM sleep and non-REM sleep) was convoluted, but by 1960 the fundamental duality of sleep was well established including the description of REM sleep in cats associated with “wide awake” EEG patterns and EMG suppression.

Hypertension in the Elderly

Topics range from basic concepts, epidemiology and trials, and evaluation and management, to pharmacological treatment, special populations, and adherence, all presented with an emphasis on the optimal management of patients. The authors examine in detail the mechanisms of hypertension in the elderly, particularly age-related changes in vascular stiffness, and methodically review the lifestyle and outcomes trials that were conducted in older persons. The problems of clinical evaluation, secondary hypertension, and target organ damage are also fully addressed, and a practical approach is provided for correctly determining blood pressure, one of the most important tasks in evaluating an older patient. Extensive discussions of pharmacological therapy detail the role of individual drug classes, including diuretics and b-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium antagonists, a-1 blockers, and combination drug therapies. Additional chapters focus on special populations, such as African Americans, patients with diabetes, and patients with arthritis, as well as on the clinician's role in improving therapeutic adherence in older patients. Offers family practitioners and general internists an up-to-date, user-friendly reference on the diagnosis, treatment, and complications of hypertension in the elderly.

Hydroboration and Organic Synthesis : 9-Borabicyclo [3.3.1] nonane (9-BBN)

Borabicyclo [3.3.1]nonane, a commercially available reagent, is the most versatile hydroborating reagent to synthesize organoboranes (B-R-9-BBN). The reagent exhibits remarkable regio-, chemo-, and stereoselectivity during hydroboration reactions. The organoboranes can be converted to C-H, C-O, C-N, C-S, C-halogen, C-metal and above all C-C bonds. In addition, the suitable substituted / unsaturated R of B-R-9-BBN can be utilized to produce dienes, enynes, allenes etc. with defined stereochemistry. 9-BBN’s derivatives have been elegantly used for the asymmetric reduction of ketone moiety. Diels-Alder and Suzuki reactions have expanded the utility of 9-BBN for the synthesis of a variety of organic compounds required for industry. Consequently, this vast field in the form of a book will be helpful to synthetic organic chemists for easy access to literature, required for chemical transformations.
