Rapid developmental switch in the mechanisms driving early cortical columnar networks

2006

The immature cerebral cortex self-organizes into local neuronal clusters long before it is activated by patterned sensory inputs. In the cortical anlage of newborn mammals, neurons coassemble through electrical or chemical synapses either spontaneously or by activation of transmitter-gated receptors. The neuronal network and the cellular mechanisms underlying this cortical self-organization process during early development are not completely understood. Here we show in an intact in vitro preparation of the immature mouse cerebral cortex that neurons are functionally coupled in local clusters by means of propagating network oscillations in the beta frequency range. In the newborn mouse, this…

Chronic Effects of Whole-Body Vibration

1986

The reactions of the body to stress from mechanical vibration, presented in the section “Acute Effects of Mechanical Vibration” (see p. 12), deal with individual organs and functions. It is now time for the following question to be asked: Are these physiological or pathophysiological changes in reality the external symptoms of a vibration-induced illness of the whole organism? Above all, some Soviet scientists are of this opinion. Andreeva-Galanina (1967) has especially called this concept “vibration illness” and has used it in the sense that the totality of vibration-induced changes in the human organism can be characterized (Rublack 1978). In this systemic “vibration illness,” Andreeva-Ga…

A case of intrasellar aneurysm simulating a pituitary adenoma

1959

A case of intrasellar aneurysm simulating a pituitary adenoma has been reported. The literature on the subject has been reviewed. The diagnostic difficulties related to intrasellar aneurysms and the role that arteriography should play in the study of chiasmatic lesions have been discussed.

Control of adenine nucleotide metabolism and glycolysis in vertebrate skeletal muscle during exercise.

1996

The turnover of adenosine triphosphate (ATP) in vertebrate skeletal muscle can increase more than a hundredfold during high-intensity exercise, while the content of ATP in muscle may remain virtually unchanged. This requires that the rates of ATP hydrolysis and ATP synthesis are exactly balanced despite large fluctuations in reaction rates. ATP is regenerated initially at the expense of phosphocreatine (PCr) and then mainly through glycolysis from muscle glycogen. The increased ATP turnover in contracting muscle will cause an increase in the contents of adenosine diphosphate (ADP), adenosine monophosphate (AMP) and inorganic phosphate (P(i)), metabolites that are substrates and activators o…

Analysis of tear proteins by one- and two-dimensional thin-layer iosoelectric focusing, sodium dodecyl sulfate electrophoresis and lectin blotting. D…

1998

· Background: Isoelectric focusing (IEF) of tear proteins has not yet been carried out in a satisfactory way. Two-dimensional (2D) electrophoresis, especially in the combination of IEF with SDS, is able to differentiate between proteins in detail. The purpose of this study was therefore to analyze tear proteins by 1D IEF alone and in combination with a 2D pattern, and by IEF followed by lectin staining. · Methods: Ampholines, covering a broad range from pH 3 to pH 10, were applied. After IEF, semi-dry blotting and incubation with a group II lectin and two group V lectins was performed. · Results: Tear proteins could be separated into 31 single bands. Tear-specific pre-albumin (TSPA), lactof…

Aneurysm clipping following endovascular coil embolization: A report of two cases

2009

Abstract BACKGROUND: Treatment of intracranial aneurysms by Guglielmi detachable coil (GDC) embolization is a useful therapeutic alternative to surgery. This procedure is attractive as a minimally invasive approach to treat cerebral aneurysms; however, is not devoid of complications or failure and retreatment, with either a surgical or endovascular technique, may often be required. CASE REPORTS: Two cases are presented in which surgery was required after coil embolization. In one case, surgical treatment was performed one month later because of regrowth and subsequent bleeding of the aneurysm. In the second case, surgical treatment was carried out six months later because of recanalization …

Canova divulgato tra «Können» e «Wollen» nell’opera di Alfred Gotthold Meyer

2014

This article is a critical introduction to the Italian translation of Meyer's Canova monograph (1898), it focuses on the editorial process and on the use of photography during this early stage of popular art history. Further consideration is given to Meyer's critical point of view in the context of the German fin-de-siècle art discourse (Burckhardt, Springer, Bode, Wölfflin, Hildebrand).
