Current teaching is that fatty infiltration into the myocardium (lipomatosis or cor adiposum) rarely aVects cardiac function. This may not be entirely true. Rupture during acute myocardial infarction has certainly been shown to be more common in the fatty heart. Fat infiltrating in the region of the conduction system is responsible for causing sudden death. Furthermore, it is possible for lipom...

The term "hyaline degeneration ", first employed by von Recklinghausen (1883), denotes a physical state rather than a chemical composition. " Hyalin" includes a heterogenous group of substances which share the properties of being translucent, refractile, and structureless (Gk, hyalos-glass). They stain readily with acid dyes, are resistant to strong acids and alkalis, and are all of a protein n...

Four case histories are reported in which the initial signs and symptoms were those of pulmonary infiltration and in which subsequently a diagnosis of myelodysplasia was made. The analysis of bronchoalveolar lavage fluid--demonstrating predominantly neutrophils and lymphocytes, and, occasionally blast cells as well as plasma cells--indicated that the pulmonary infiltration was related to the my...

Infiltration into the soil is restricted if the movement of displaced air is hampered. In this study, separate infiltration experiments were performed where the air could escape only through capillary glass tubes (three different diameters were used). Control experiments, where the air movement was not restricted, were performed also. During the experiments both air pressure and the cumulative ...

Thinning is a crucial practice in the forest ecosystem management. The soil infiltration rate and water storage capacity of pine-oak mixed forest under three different thinning intensity treatments (15%, 30%, and 60%) were studied in Qinling Mountains of China. The thinning operations had a significant influence on soil infiltration rate and water storage capacity. The soil infiltration rate an...

IInfiltration rate and hydraulic conductivity are immensely important parameters for evaluating the hydrology of subsurface environments. Specifically, in disposal wells schemes and in artificial recharge plans both properties must be correctly assessed to better analyze the performance of these installations. In a new research, tanker water and rainfall runoff were injected into a 22.5 m deep ...

Cellular immune responses can be initiated via peptide presentation by specialized antigen presenting cells, dendritic cells (DCs), which stimulate naïve T cells. The trafficking of DCs and T cells is regulated by chemokines such as CCL21. CCL21 is normally expressed in the lymphoid organs and coordinates the interactions between DCs and T cells, thereby contributing to the initiation of T cell...

Developing correlations between various soil parameters are considered the major challenge to diminish time and cost associated with field measurements. Soil hydraulic and physical properties were extensively characterized using tension disc infiltrometer and soil sampling in a silty clay agricultural field in Kalaat El-Andalous, Tunisia. Tension disc infiltrometer experiments were conducted at...
