Cricket combined mechanoreceptors and kicking response

1977

1. Only those filiform hairs on the cerci ofGryllus, which are coupled with campaniform sensilla, show a) a thickening of the hair shaft at the height of the upper ring lamella of their sockets and b) a thin cuticular membrane, which surrounds their sockets. While thefiliform hairs themselves are deflected either parallel to the long axis of the cerci or perpendicular to it, thesockets of the filiform hairs may be deflected preferentially in the proximal and distal direction. 2. Spike potentials can be recorded from the sensory cells of the filiform hairs as long as these are deflected in a weak air current, but not during permanent deflection in strong air streams when they touch the inner…

Bronchiektasen und Infekthäufigkeit bei Alpha-1-Antitrypsin-Mangel

1995

UNLABELLED PURPOSE of this study was to determine the prevalence of bronchiectasis in patients suffering from alpha-1-antitrypsin deficiency and to compare its extent with the frequency of infections. MATERIAL AND METHODS High-resolution CT examinations (HRCT) of 23 patients with alpha-1-antitrypsin deficiency were retrospectively assessed for extent, severity and localisation of bronchiectasis, bronchial wall thickening and extent of emphysema. Chest radiographs and clinical records were available for correlation. RESULTS HRCT scans showed bronchiectasis in 14 of 23 patients, bronchial wall thickening in 3/14, and panlobular emphysema in 23/23. Chest radiographs showed bronchiectasis in 4/…

Cardiovascular effects of occupational exposure to urban airborne pollution on a group of newsagents in the city of Palermo

2014

Aims: To verify the possible correlation between exposure to airborne particulate matter the average size less than 10 μm (PM 10) of a group of newsagents working in kiosks in Palermo and evidence of carotid intimal thickening. Materials and methods: data were collected relating to environmental monitoring of airborne pollutants. We have selected a sample of newsagents, who were submitted to some clinical investigations, including the carotid echo-color doppler examination. Results: The results show no correlation between the location of the kiosks, and the presence of intimal thickening. Conclusion: Exposition to urban pollutants in Palermo is likely homogenous in the different areas and c…

Circumferential spicule growth by pericellular silica deposition in the hexactinellid sponge Monorhaphis chuni.

2011

SUMMARY The giant basal spicule of the hexactinellid sponge Monorhaphis chuni represents the longest natural siliceous structure on Earth. This spicule is composed of concentrically arranged lamellae that are approximately 10 μm thick. In the present study, we investigated the formation of outer lamellae on a cellular level using microscopic and spectroscopic techniques. It is shown that the formation of an outermost lamella begins with the association of cell clusters with the surface of the thickening and/or growing spicule. The cells release silica for controlled formation of a lamella. The pericellular (silica) material fuses to a delimited and textured layer of silica with depressions …

Application of seaweeds to develop new food products with enhanced shelf-life, quality and health-related beneficial properties

2017

International audience; Edible seaweeds are a good source of antioxidants, dietary fibers, essential amino acids, vitamins, phytochemicals, polyunsaturated fatty acids, and minerals. Many studies have evaluated the gelling, thickening and therapeutic properties of seaweeds when they are used individually. This review gives an overview on the nutritional, textural, sensorial, and health-related properties of food products enriched with seaweeds and seaweed extracts. The effect of seaweed incorporation on properties of meat, fish, bakery, and other food products were highlighted in depth. Moreover, the positive effects of foods enriched with seaweeds and seaweed extracts on different lifestyl…

Die sonographische Gallenblasenwandverdickung und ihre diagnostische Bedeutung bei intensivpflichtigen Patienten

2008

In a prospective study including 398 intensive-care patients, we analysed the ultrasonographic relevance of a gallbladder wall thickening. In 24 of 398 (6%) cases a wall thickening was found that could be differentiated into two types of walls. In 20.8% (5/24) the gallbladder wall thickening was an expression of an acute cholecystitis. In further differential diagnosis of a gallbladder wall thickening pathological states with hypoalbuminaemia occupy the prime position. The pathological mechanism has not yet been completely clarified. Hypoalbuminaemia without inflammatory alterations of the organ was found in 37.5% of the cases with gallbladder wall thickening. In 41.6% of the patients the w…
