Qualitative features of the secondary xylem of Licaria present a rather uniform structural profile. Constant differences in primarily quantitative characters lead to the formation of speeies groups wh ich loosely correspond to infrageneric sections based on floral and vegetative morphology. This subdivision is strongly corroborated by the highly variable secondary phloem structurc revealing considerable diversity in type and distribution of sc1erenchymatic tissues. Inorganic inclusions in the secondary xylem, crystals and silica, constitute an important diagnostic tool for differentiating certain species and species groups, but are hardly of importance in the bark.

Peripheral blood mononuclear cells were isolated from noninfected control cows and from cows with either subclinical or clinical paratuberculosis (Johne s disease). Cells were incubated for 6, 12, 24, and 48 hours in complete medium with the following mitogens: concanavalin A (ConA), phytohemagglutinin-P (PHAP), pokeweed mitogen (PWM), and Escherichia coli lipopolysaccharide. In addition, cells were incubated for the same time periods with a Mycobacterium paratuberculosis sonicate (MpS) and live and heat-killed M. paratuberculosis at 10:1 bacteria: cell ratio. After incubation, cell-free supernatants were analyzed for y-interferon (γ-IFN) production. Cells from subclinical cows produced significantly higher levels of γ-IFN than did cells from clinical animals after stimulation with mitogens ConA, PHAP, and PWM. Levels of γ-IFN produced by noninfected control animals generally followed the pattern of those of subclinical animals. After incubation with MpS, significantly greater quantities of γ-IFN were produced by cells isolated from subclinical animals than by cells from clinical cows and noninfected controls. Stimulation of cells with heat-killed or live M. paratuberculosis evoked a similar response. This study indicates that γ-IFN production by peripheral blood mononuclear cells in response to M. paratuberculosis antigen may be an important diagnostic tool for the detection of paratuberculosis in subclinically affected animals.

Set Up

Semen analysis remains the most important diagnostic tool for the study of male infertility to date. For this reason, and because of the ease of carrying out this analysis, examination of seminal fluid should be among the first diagnostic steps in cases of suspected infertility, prior to subjecting the man’s partner to long and complex diagnostic tests. The efficacy of an examination of seminal fluid depends on the experience and ability of the seminologist, who must first undertake a subjective analysis of fundamental parameters such as motility and morphology. Moreover, laboratories specialized in such analyses may apply different criteria to the evaluation of sperm parameters, making it extremely difficult to compare tests carried out in different laboratories (1). In an attempt to resolve these problems of inconsistency, and in order to standardize laboratory techniques, a committee of experts from the WHO established guidelines for semen analysis in 1980 (an updated version was published in 1999) (2). In recent years, numerous other methods of semen analysis capable of providing in-depth diagnostic information on the fertilising capacity of spermatozoa have become available. The computer-aided sperm analysis (CASA) system is a technique for sperm analysis designed to provide objective data on sperm motility (3). Because of persisting difficulties in software set-up (4), it should not be used for routine analysis, but rather as a research tool. At the same time, significant advances have been made in the study of sperm morphology through the use of scanning and transmission electron microscopes (5). Finally, within the past decade several tests capable of evaluating the integrity of sperm components, such as the membrane, acrosome, DNA, and nuclear protein, have been developed and put into use. These more complex and costly analytical tools should be considered of secondary or tertiary importance, and are to be carried out in specific cases only after standard semen analysis. Standard semen analysis remains the first and fundamental diagnostic tool.

And Function

There is an increase in the number of dentists using orthodontic treatment for anterior tooth alignment. This is either combined with additive bonding or interproximal reduction; knowing “when to” and “how much” requires an understanding of the anterior ratio. This case report explains how to use the anterior ratio to help provide optimal aesthetics and function for the ortho-restorative patient. The anterior ratio is an important diagnostic tool required for both disciplines of orthodontics and restorative dentistry which is often overlooked. The case report demonstrates the use of the Invisalign orthodontic appliance and the corresponding ClinCheck software to help achieve the proposed treatment goals.
