EFFECT OF CHRONIC ADMINISTRATION OF LOW DOSES OF POLYPEPTIDES OF CATTLE CEREBRAL CORTEX AND METHIONYL-GLUTAMYL-HISTIDYL-PHENYLALANYL-PROLYL-GLYCYL-PROLINE ON BEHAVIORAL RESPONSES OF RAT OFFSPRING.

In the modern world, anyone is susceptible to the effects of stress, regardless of age, gender, culture, and social status. Stress at an early age accelerates long-term changes in the functional properties underlying emotional perception and therefore may alter the stress response later in life. Unfortunately, the interdisciplinary approach in stress research emphasised the study of stress phenomenon in the development of this or that pathology or manifestation of appropriate reactions under the influence of this or that factor, i.

Catastrophic growth of totally molten magma chambers in months to years.

The vertical growth rate of basaltic magma chambers remains largely unknown with available estimates being highly uncertain. Here, we propose a novel approach to address this issue using the classical Skaergaard intrusion that started crystallizing from all margins inward only after it had been completely filled with magma. Our numerical simulations indicate that to keep the growing Skaergaard magma chamber completely molten, the vertical growth rate must have been on the order of several hundreds to a few thousands of meters per year, corresponding to volumetric flow rates of tens to hundreds of cubic kilometers per year.

A 5-km-thick reservoir with > 380,000 km of magma within the ancient Earth's crust.

Several recent studies have argued that large, long-lived and molten magma chambers may not occur in the shallow Earth's crust. Here we present, however, field-based observations from the Bushveld Complex that provide evidence to the contrary. In the eastern part of the complex, the magmatic layering continuously drapes across a ~ 4-km-high sloping step in the chamber floor.

Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers.

The classical paradigm of the 'big magma tank' chambers in which the melt differentiates, is replenished, and occasionally feeds the overlying volcanos has recently been challenged on various grounds. An alternative school of thought is that such large, long-lived and largely molten magma chambers are transient to non-existent in Earth's history. Our study of stratiform chromitites in the Bushveld Complex-the largest magmatic body in the Earth's continental crust-tells, however, a different story.

[Subclinical left ventricular dysfunction in patients with type 2 diabetes mellitus].

Background: Recent studies have shown a high prevalence of asymptomatic forms of heart failure in patients with type 2 diabetes mellitus. The presence of even subclinical forms of heart failure in type 2 DM is associated with a negative prognosis of the disease, leading to a significant increase in the frequency of hospitalizations and mortality.

Aims: Identification of left ventricle subclinical dysfunction in terms of its diastolic function, deformation parameters and rotational properties of the myocardium in patients with type 2 diabetes.
