BACKGROUND AND OBJECTIVE Accelerated bone loss is a well recognized complication after cardiac transplantation (HTx). The role of an immunosuppressive-induced hypogonadism, a well-known cause of osteoporosis in men and its prevention are less defined

The recombination of methyl radicals is the major loss process for methyl in the atmospheres of Saturn and Neptune. The serious disagreement between observed and calculated levels of CH3 has led to suggestions that the atmospheric models greatly unde

The potential importance of OBrO in atmospheric chemistry has been suggested recently. Although there appear to be no experimental measurements of deltaH(OBrO), estimated values range from 70 to 152 kJ/mol. In the present investigation, the appearanc
