Anatomy of cochlea and round window

2010

One of the most important functions of the ear is sound recepction, particularly the detection of amplitude and frequency of the sound waves by Corti's organ. The latter is a sensory structure located in the cochlear duct (middle scale), consisting of hair cells lying above the basilar membrane. The cochlear duct is surrounded by two cavities containing perilymph: the scala vestibularis and the scala tympani. The sound reception mechanism involves several other components of the ear such as malleus, incus and stapes, in the tympanic cavity, and the oval and round windows. The movement of the stapes on the oval window, that is adjacent to the scala vestibularis, generates pressure waves in t…

Responsive versus Treatment-Resistant Perpetrators in Batterer Intervention Programs: Personal Characteristics and Stages of Change.

2020

This article aims to identify different personal characteristics in treatment-responsive and treatment-resistant perpetrators of intimate partner violence who completed a batterer intervention program (BIP). The sample consists of 105 perpetrators of intimate partner violence who were court-mandated to a community-based cognitive behavioral program. Perpetrators were classified by professionals as resistant or responsive to treatment based on the stage of change they reached upon completion of the program. The results show that before starting the intervention program, treatment-resistant perpetrators scored higher than treatment-responsive perpetrators in external responsibility attributio…

CD1a immunopositivity could help to address prognosis of intestinal-type Barrett's metaplasia

Pesticide occurrence in the waters of Júcar River, Spain from different farming landscapes.

2017

A combined methodology to identify and quantify farming chemicals in the entire Júcar River basin has been developed. The procedure consisted of the application of environmental forensic criteria associating laboratory analytical samples, cartographic analysis using Geographical Information Systems (GIS) and synthetic statistical analysis. Sampling involved the collection of 15 samples in surface waters distributed alongside the Júcar River and its two main tributaries (Cabriel and Magro Rivers). The analytical procedure involves generic sample extraction and selective determination of up to 50 target pesticides by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Geogra…

Mitochondria-related encephalomyopathies.

1989

Owing to advances in morphological and biochemical techniques, the mitochondria-related myopathies and encephalomyopathies have emerged as a still rapidly growing group of primary and secondary metabolic disorders, which may extend from infancy to late adulthood. Impairment of the biochemically diversified mitochondria is reflected in an enormous number of deficiencies, often affecting several mitochondrial enzymes in the same patient; morphologically abnormal mitochondria are common and are thus not specific to individual mitochondrial enzyme deficiencies. Skeletal muscle biopsies have provided a wealth of data through histological and histochemical studies and from isolated mitochondria. …

Uranium from German Nuclear Power Projects of the 1940s— A Nuclear Forensic Investigation

2015

Here we present a nuclear forensic study of uranium from German nuclear projects which used different geometries of metallic uranium fuel. Through measurement of the (230)Th/(234)U ratio, we could determine that the material had been produced in the period from 1940 to 1943. To determine the geographical origin of the uranium, the rare-earth-element content and the (87)Sr/(86)Sr ratio were measured. The results provide evidence that the uranium was mined in the Czech Republic. Trace amounts of (236)U and (239)Pu were detected at the level of their natural abundance, which indicates that the uranium fuel was not exposed to any major neutron fluence.

Child behaviour and adult personality: comparisons between criminality groups in Finland and Sweden

2000

Background; Lately there has been an increasing interest in whether personality traits are associated with criminal behaviour in male and female subjects. Criminality and alcohol abuse are often associated. Delinquent adolescents are impulsive and danger seeking. Childhood aggression may be a precursor of adult criminality. Method Using longitudinal data, adult personality and childhood behaviours were examined for groups of non-criminals and criminals of Finnish (n = 268) and Swedish (n + 169) samples, and crime groups were compared in the two cultures. Karolinska Scales of Personality (KSP) were given at adult age and the participants had been observed and rated by their teachers in respe…

Skeletal muscle oedema and muscle fibre necrosis during septic shock. Observations with a porcine septic shock model

1994

In domestic pigs, intermitted application of Escherichia coli-endotoxin was used to create an animal model for a prolonged hypo- and hyperdynamic septic shock-like state and to investigate mechanisms of multiple organ failure. Here, we describe the changes in skeletal muscle after 18 h (2 animals) and 48 h (6 animals) of septic shock. Two pigs for each observation period that received physiologic saline solutions instead of endotoxin served as controls. The earliest lesions were endothelial cell damage with endomysial oedema and swelling of mitochondria in muscle fibres. With increasing degree of endothelial cell damage, pericytes showed degenerative changes with cytoplasmic fragmentation a…

Preliminary approach to elucidate the role of pigment as a binding site for drugs and chemicals in anagen hair: differential uptake of 3 H-haloperido…

2002

A striking difference was observed for cellular-bound drug in HaCaT and Sk-Mel-1 cells for a fixed drug exposure time of 72 h and varying 3H-haloperidol concentrations in the culture media. Drug uptake was dependent on drug concentration and linearly correlated for both the non-pigment- and the pigment-producing cells which however was different in magnitude. In an additional investigation the time course of drug uptake during 3H-haloperidol exposure (400 pmol/ml; 28 days) revealed increasing drug concentrations in the Sk-Mel-1 population, whereas drug concentrations in the keratinocytes reached a plateau within a short time period. In contrast to the HaCaT cells no tendency to saturation w…
