How structures in bovine hoof epidermis are influenced by nutritional factors.

The structure of the hoof epidermis is the link between nutrition and horn quality. The aim of this study was to demonstrate the relationship of single structures in the process of keratinization and cornification of bovine hoof epidermis to certain nutritional factors such as lipids, minerals and vitamins. Furthermore, we wanted to show the structural changes in the dyskeratotic epidermis caused by an insufficient supply of keratinizing epidermal cells.

History of atmospheric lead deposition since 12,370 (14)C yr BP from a peat bog, jura mountains, switzerland.

A continuous record of atmospheric lead since 12,370 carbon-14 years before the present (14C yr BP) is preserved in a Swiss peat bog. Enhanced fluxes caused by climate changes reached their maxima 10, 590 (14)C yr BP (Younger Dryas) and 8230 (14)C yr BP. Soil erosion caused by forest clearing and agricultural tillage increased lead deposition after 5320 (14)C yr BP.

Emergency department productivity improvement through a management-staff partnership.

How can the drastically varied emergency department patient volumes be balanced with optimum staff scheduling? The author uses a case study to illustrate a successful management-staff partnership model and provides recommendations to help managers and administrators initiate and guide productivity improvement.

Pneumocystis carinii induces interleukin 6 production by an alveolar epithelial cell line.

Background: Pneumocystis carinii (PC) infection often results in severe pneumonia in immunocompromised patients. Attachment of PC organisms to alveolar epithelial cells is a hallmark of PC pneumonia; however, few studies have investigated the response of alveolar epithelial cells to PC infection.

Methods: Interleukin 6 (IL-6) is a multifunctional cytokine that is produced by alveolar epithelial cells in response to a variety of stimuli.

What's behind those satisfaction surveys?

Health plans eagerly collect and disseminate evidence of contented enrollees, but what do member satisfaction surveys really reveal? Unless methodology is reported along with results, the answer is, Not Much.

[Discovery of a human hand?].

We report on an unusual bone finding in the northeast of Germany. The "human hand of a child" was identified as the left foot of a baboon.

Management of sports-induced skin wounds.

Skin wounds are common in sports but are rarely documented by the certified athletic trainer. The literature is unclear about wound types, and none of the articles reviewed reported frequencies. The purpose of this paper is to discuss the frequency of common athletic skin wounds and their specific management.

[Structural factors influencing the horn quality and predilection sites for diseases at the bottom surface of the bovine hoof].

The quality of the horn of the cattle hoof varies in the different segments of the ground surface adapted to weight bearing. Horn quality is influenced by the following main factors: the keratin proteins as the most important intracellular factor, the intercellular cementing substance as the intercellular factor, and the architecture of the cluster of horn cells, i.e.

[A lectin histochemical study of the epidermis off the skin and the hoof of horses].

Carbohydrate moieties of cell membranes in the epidermis of equine skin and hoof were investigated using lectin-histochemistry. The loss of desmosomes during keratinization leads to a reduced lectin affinity. Lectin binding capacity of the intercellular matrix in the stratum corneum of the epidermis is weak compared to that of the intercellular kitt of the hoof.

Changes in cardiovascular function during inversion.

Although inversion therapy is used increasingly as a therapy for musculoskeletal back disorders, its effects on cardiovascular function have not been systematically determined. Heart rate, blood pressure and echocardiographic measurements were performed in 20 normal male volunteers before, during and after bent-knee inversion. Compared to control measurements in the supine position, inversion significantly increased heart rate, systolic and diastolic blood pressure, rate-pressure product, systemic vascular resistance and left ventricular (LV) wall stress.
