Screening for mutations in exon 4: Of the LDL receptor gene: Identification of a new deletion mutation
DNA from 14 unrelated New Zealand familial hypercholesterolaemia (FH) heterozygotes, originating from the United Kingdom, was screened for mutations in exon 4 of the low density lipoprotein receptor (LDLR) gene. One patient ...
Evidence that the stimulatory effect of neurotensin on dopamine release in rat nucleus accumbens slices is independent of dopamine D2-receptor activation
Neurotensin (NT, 10-9 M and 10-7 M) increased the electrically stimulated release of [3H]dopamine (DA) in rat nucleus accumbens slices. This effect was not altered by activation of DA D2-receptors with high or low ...

Combined use of pleural adenosine deaminase with lymphocyte/neutrophil ratio: Increased specificity for the diagnosis of tuberculous pleuritis
Increased pleural fluid adenosine deaminase (ADA) activity is classically associated with tuberculous pleuritis. However, increased activity can also occur in a number of other diseases and this may negatively affect the ...
Treatment of multiple rib fractures. Randomized controlled trial comparing ventilatory with nonventilatory management
We studied the treatment of multiple rib fractures in NIC, comparing ventilatory with nonventilatory methods in 69 patients who were randomly allocated to one of the following two treatments: (1) a CPAP mask combined with ...
Tracheostomy and peristomal recurrence
Emergency tracheostomy prior to laryngectomy for laryngeal carcinoma has been associated with peristomal recurrence. Is the peristomal recurrence caused by the tracheostomy per se, or is it due to the association of ...
Human papillomavirus DNA in oral squamous cell carcinomas from an African population sample
Background. The incidence of oral squamous cell carcinoma (OSCC) is on the increase in developing countries. Materials and Methods. Formalin fixed paraffin embedded blocks of OSCCs from a Black South African population ...
Correlation between p53 gene mutation, p53 protein labeling and PCNA expression in oral squamous cell carcinomas
Background: The prevalence of oral squamous cell carcinoma (OSCC) among the Black community in South Africa is unacceptably high. The association between p53 protein, and PCNA overexpression and the presence of p53 gene ...
Warthin's tumour is not an Epstein-Barr virus related disease
Background: The histogenesis of Warthin's tumour (WT) is controversial. A possible role for Epstein-Barr virus (EBV) has been suggested. Materials and Methods: Twenty formaldehyde-fixed, paraffin-embedded blocks of WT from ...
Papulonecrotic tuberculid in children: A report of eight patients
Papulonecrotic tuberculid (PNT), a form of cutaneous tuberculosis (TB), is uncommon in children. We identified eight children (six girls and two boys) with PNT. Their ages ranged from 19 to 139 months (median: 47.5 months, ...
