Mycobacteriosis is a common disease of laboratory zebrafish (Danio rerio). Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more wide spread and not associated with high mortality. Identification of mycobacterial infections to...

This paper discussed the human electrocardiogram, the instrumentation
used to graphically record it, and the design and performance
of a specialized system for vector cardiography: the Vector Electrocardioscope
(VECS) System. The introduction reviews in considerable
detail the pertinent known physiology of the heart, especially the
electrophysiology responsible for the genesis...
Mycobacterium avium subsp hominissuis (MAH) is an opportunistic environmental pathogen that causes respiratory and gastrointestinal illness in immunocompromised persons such as those with chronic respiratory diseases or AIDs, respectively. In recent years, there has been a significant increase in the incidence of nontuberculous mycobacterial (NTM) lung infections, including in cystic...
Mycobacterium avium is a ubiquitous environmental organism found in both water and soil. It can cause disease in patients with previous pulmonary conditions, as well as immunosupressed patients, with the most prevalent being AIDS patients. Studies have indicated that passage through amoeba, a common environmental protozoa, increases virulence of M....

Observations of annual growth and size and color of leaves and fruit are helpful in determining fertilizer needs. In addition, leaf analysis
indicates which elements are present in adequate, deficient, or excessive amounts. Soil analysis is useful in predicting the need for lime applications. Suspect a nutrient deficiency if poor...

Many factors can cause distorted growth in grapevines. One cause of distorted growth is a disorder known as Short Shoot Syndrome (SSS), which is associated with mite feeding damage. However, similar abnormal growth symptoms can be caused by spring frost damage, herbicide damage, vine imbalance (overcropping of vines), nutrient deficiency...
