Distribution and muscle-sparing effects of clenbuterol in hindlimb-suspended rats.

Based on their anabolic properties in skeletal muscles, beta-adrenergic agonists are of interest as potential countermeasures to microgravity-induced skeletal muscle atrophy. The levels of clenbuterol (Cb), a beta(2)-adrenergic agonist, in both plasma and skeletal muscle were higher in hindlimb-suspended rats than in their nonsuspended Cb-treated controls. Cb treatment was shown to help maintain the body weight in suspended rats, while reducing the amount of mesenteric fat. However, hindlimb suspension attenuated Cb's lipolytic effects. In skeletal muscle, the magnitude of response to unloading and Cb treatment followed a general regional pattern and was muscle and type specific. The highest magnitude of response to unloading was in predominantly slow-twitch muscles, and the least responsive were the predominately fast-twitch muscles.

Restrictive covenants in professional employment contracts.

For a court to sustain a restrictive covenant with anticompetition as its major thrust does violence to our individual rights. There is no duty for a former employee not to compete as an incident of employment. Employers who seek to enforce restrictive covenants to protect their practice areas are asking the court to place on one side of the scales of justice the birthright of a newcomer to engage in the competitive marketplace and to place on the other side the right of the established group to have a public market area reserved exclusively for their benefit by prior claim. The court is being asked to take valuable legal rights to pursue competitive opportunities from one person or business and give them to the other person or business. In a legal sense, this is not easy to justify. Without something specific and private to protect other than public competitive opportunities, a restrictive covenant may violate public policy by casting a chilling effect on competition, may be abusive to constitutional equal protection, does violence to the concept of free enterprise, and tends to deny communities the services of highly trained professionals that may otherwise be hard to replace. The law of restrictive covenants varies from one state to another. Some jurisdictions have strayed from the traditional position detailed here and often are inclined to protect the employer's right to a service area for a specified term. The services of a local attorney should be obtained when it is necessary to deal with a contractual restrictive covenant.

How to lose informed consent.

It is possible to begin a medical procedure with informed consent and to complete the procedure without the patient's consent. The question is, how do you lose informed consent between the beginning and the end of a procedure?
