25. Amnesia following the rupture and repair of an anterior communicating artery aneurysm.
Clinical analysis and neuropsychological criteria derived from experimental studies of human amnesic syndromes, particularly the alcoholic Korsakoff's syndrome, have been used to characterise an unusual form of amnesia that occurred in two patients after rupture of an anterior communication cerebral artery aneurysm. Intraoperative observation and multiple CT

26. Neuropsychological pattern of striatonigral degeneration: comparison with Parkinson's disease and progressive supranuclear palsy.
To study the neuropsychological pattern of striatonigral degeneration (SND), 14 consecutive patients with probable SND were submitted to an extensive battery of neuropsychological tests. Compared with controls the performance of patients with SND was impaired on category and phonemic fluency, frontal behaviours, trail making test A and B, and free recall of

27. Induction of mucosal immunity by intranasal application of a streptococcal surface protein antigen with the cholera toxin B subunit.
The level and distribution of isotype-specific antibodies in various secretions and of antibody-secreting cells in corresponding lymphoid organs and tissues were compared in mice immunized with Streptococcus mutans surface protein antigen I/II (AgI/II) conjugated to the cholera toxin B subunit (CTB), given intranasally (i.n.) or intragastrically (i.g.), with

28. Online access to MEDLINE in clinical settings: impact of user fees.
The effect of introducing user fees on the frequency and quality of MEDLINE searching with GRATEFUL MED by physicians in clinical settings was tested. After training and free use (prior study), consenting participants were randomly allocated to pay searching costs (pay group) or continue without fees (no pay group). Fifty-nine physicians participated. Among

29. Association of serum lipids with coffee, tea, and egg consumption in free-living subjects.
The associations of serum lipids with coffee, tea, and egg consumption were examined in a survey of 658 men in Israel. A significant, positive association was found between coffee consumption and serum total cholesterol (TC), mainly reflecting a difference in the low density lipoprotein cholesterol (LDL-C). Among the subjects aged 20-39, the difference in TC

30. Verbal and Nonverbal Emotional Memory Following Unilateral Amygdala Damage
The amygdala is involved in the normal facilitation of memory by emotion, but the separate contributions of the left and right amygdala to memory for verbal or nonverbal emotional material have not been investigated. Fourteen patients with damage to the medial temporal lobe including the amygdala (seven left, seven right), 18 brain-damaged, and 36 normal con

31. Using POSTDOC to recognize biomedical concepts in medical school curricular documents.
Recognition of the biomedical concepts in a document is prerequisite to further processing of the document: medical educators examine curricular documents to discover the coverage of certain topics, detect unwanted redundancies, integrate new content, and delete old content; and clinicians are concerned with terms in patient medical records for purposes rang

32. A role for surface lymphotoxin in experimental autoimmune encephalomyelitis independent of LIGHT
In studies using genetically deficient mice, a role for the lymphotoxin (LT) system in the pathogenesis of experimental autoimmune encephalomyelitis (EAE) has remained controversial. Here, we have reassessed this conclusion by using a fusion protein decoy that blocks the LT pathway in vivo without evoking the developmental defects inherent in LT-deficient mi

33. Immunotherapy of a human papillomavirus type 16 E7-expressing tumor by administration of fusion protein comprised of Mycobacterium bovis BCG Hsp65 and HPV16 E7
Human papillomavirus type 16 (HPV16) infection has been linked to the development of cervical and anal dysplasia and cancer. One hallmark of persistent infection is the synthesis of the viral E7 protein in cervical epithelial cells. The expression of E7 in dysplastic and transformed cells and its recognition by the immune system as a foreign antigen make it

34. Mammographic screening: measurement of the cost in a population based programme in Victoria, Australia.
STUDY OBJECTIVES--To estimate the cost per woman participating in a mammographic screening programme, and to describe methods for measuring costs. DESIGN--Expenditure, resource usage, and throughput were monitored over a 12 month period. Unit costs for each phase of the screening process were estimated and linked with the probabilities of each screening outc

35. Prevalence and correlates of neuropsychological deficits in amyotrophic lateral sclerosis.
OBJECTIVE: To determine the prevalence and correlates of neuropsychological impairment in a large cohort (n = 146) of patients with typical, sporadic (non-familial) amyotrophic lateral sclerosis. METHODS: A battery of neuropsychological tests was administered to patients with amyotrophic lateral sclerosis who were attending a monthly outpatient clinic or who

36. Reversible inactivation of the nucleus basalis magnocellularis induces disruption of cortical acetylcholine release and acquisition, but not retrieval, of aversive memories
The basal forebrain complex, which includes the nucleus basalis magnocellularis (NBM), provides widespread cholinergic and γ-aminobutyric acid-containing projections throughout the brain, including the insular and pyriform cortices. A number of studies have implicated the cholinergic neurons in the mediation of learning and memory processes. However, the ro
