The Distribution of Carcinogen Metabolizing Enzymes in the Mouse Liver: Comparison of Parenchymal and Non-Parenchymal Cell Populations
1987
The distribution of aminopyrine N-demethylase (APND), ethoxy- resorufin O-deethylase (ERRD), epoxide hydrolase (EH) and glutathione transferase (GST) activities in parenchymal (PC) and non-parenchymal (NPC) cell populations of control and Aroclor 1254-treated C57BL/6N and DBA/2N mice was determined. Furthermore, the metabolism of benzo(a)- pyrene (BP) in PC and NPC of both Aroclor 1254-treated mice strains was examined. Measurable activities of all enzymes investigated were detected in control PC as well as NPC of both mice strains; in all instances the PC possessed greater enzyme activities than did the NPC. The PC and NPC of DBA/ 2N mice had significantly lower ERRD and EH activities than…
Role of Parenchymal Versus Non-Parenchymal Cells on the Control of Biologically Reactive Intermediates
1986
The non-parenchymal cells (NPC) of the liver have the potential to significantly influence the formation of reactive intermediates in the liver because of their critical location along the sinusoids where they are the first cells to encounter blood borne xenobiotics. To study the possible role of the NPC in the metabolism of xenobiotics, populations of NPC and parenchymal cells (PC) were prepared from rats and various xenobiotic metabolizing enzyme activities investigated. The specific activity of every enzyme studied was 12 to 1000% higher in the PC than in the NPC populations and the pattern of activities between the 2 populations was remarkably different. The NPC also displayed a more dr…
Contribution to the Knowledge of Dermatophytic Invasion of Hair
1970
We have used the scanning electron microscope to investigate the changes that occur in scalp hair during infection with Trichophyton violaceum . We provide information on the morphology of these dermatophytes and present evidence that their hyphae dig tunnel-like burrows into the hair shaft, dissociating hair into keratin fibrils.
Detection of the lunasin peptide in oats (Avena sativa L)
2013
We report the first discovery of lunasin in oats (Avena sativa L). Lunasin is a novel cancer preventive, anti-inflammatory and cholesterol-reducing peptide originally isolated from soy and later found in cereals (barley, rye, wheat, triticale). Lunasin was detected in oats using LC–MS/MS analysis. The chromatograms and mass spectra of lunasin isolated from five oat genotypes were compared with those of the synthetic lunasin peptide. We measured the lunasin content in harvests of two years and found that all tested oat genotypes contained the lunasin peptide. However, we observed genotype-related fluctuations in the lunasin content. Notably, the middle early oat variety ‘Ivory’ contained the…
Langer-Giedion syndrome with interstitial 8q-deletion.
1982
We describe a 12-year-old girl with Langer-Giedion syndrome (tricho-rhino-phalangeal syndrome type II) who also had vertebral malformations. Chromosome analysis identified an interstitial del(8q): 46,XX,del(8)(pter leads to q22::q234 leads to qter) as a cause of this syndrome.
Oromandibular dystonia: A dental approach
2010
Oromandibular dystonia consists of prolonged spasms of contraction of the muscles of the mouth and jaw. Primary idiopathic forms and secondary forms exist. Secondary dystonia develops due to environmental factors; some cases of cranial dystonia after dental procedure have been reported, but the causal relationship between these procedures and dystonia remains unclear. Traumatic situations in the mouth, such as poor aligned dentures or multiple teeth extractions may cause an impairment of proprioception of the oral cavity, leading to subsequent development of dystonia. The clinical characteristics of oromandibular dystonia are classified according to the affected muscles. The muscles involve…
An Ethnographic Study of Deaf Refugees Seeking Asylum in Finland
2019
Deaf asylum seekers are a marginalized group of people in refugee and forced migration studies. The aim of this paper is to explore and highlight the experiences of deaf asylum seekers in the asylum procedure in Finland. The data come from linguistic ethnographic methods, interviews, and ethnographic observation with 10 deaf asylum seekers. While living in the reception centers, the study participants have faced a range of linguistic and social challenges. The findings show that language barriers appeared from day one after the participants&rsquo
Socio-emotional Problems Experienced by Deaf and Hard of Hearing Students in Ethiopia
2015
This study compares the socio-emotional problems experienced by deaf and hard of hearing (DHH) students with those of hearing students in Ethiopia. The research involved a sample of 103 grade 4 students attending a special school for the deaf, a special class for the deaf and a regular school. Socio-emotional problems were measured using Goodman's self-report measure, the Strengths and Difficulties Questionnaire for children and adolescents. Participants were selected from seven towns in Ethiopia. The results show that, compared to the hearing sample, the DHH students experienced more severe socio-emotional problems across all dimensions, regardless of whether they were in special classes o…
Time reproduction of structured auditory events by deaf and hearing subjects
2009
Congenital deafness affects different aspects of information processing and time perception. In deafness the accuracy of duration judgments seems to be linked to differences in the use of conventional time units, applied strategy as well as cognitive processes such as attention or working memory (Kowalska & Szelag, 2006). The present experiment investigated the effect of different event structures on duration reproduction in deaf and normal hearing subjects. The accuracy and variability of performances were calculated respectively by means of the absolute error score and coefficient of variation of time reproductions. Results showed a global underestimation of durations for all subjects; mo…
How to improve communication with deaf children in the dental clinic
2007
It may be difficult for hearing-impaired people to communicate with people who hear. In the health care area, there is often little awareness of the communication barriers faced by the deaf and, in dentistry, the attitude adopted towards the deaf is not always correct. A review is given of the basic rules and advice given for communicating with the hearing-impaired. The latter are classified in three groups ? lip-readers, sign language users and those with hearing aids. The advice given varies for the different groups although the different methods of communication are often combined (e.g. sign language plus lip-reading, hearing-aids plus lip-reading). Treatment of hearing-impaired children…
