Human hepatocellular carcinoma tumor xenografts

Castrated or sham-operated male athymic mice were inoculated with cells from the human hepatocellular carcinoma cell line PLC/PRF/5. There were no significant differences between the two groups with respect to the number of animals developing tumors, the time to tumor development, or the subsequent rate of increase in either tumor base area or mouse serum alpha-fetoprotein concentration. Androgen receptors were assayed in nuclei obtained from three separate liver cancer cell lines and from normal adult human liver. Similar concentrations, ranging from 235 to 550 fmol/mg DNA, of nuclear androgen receptors were detected in all tissues. Low percentages of androgen receptors were retained on DNA-cellulose. Although the presence of receptors implies the potential for metabolic effects of androgens in normal and malignant liver, our in vivostudies suggest that castration does not alter significantly the growth of liver cancer xenografts in athymic mice.     

Office versus Home-Based Family Therapy for Runaway, Alcohol Abusing Adolescents: Examination of Factors Associated with Treatment Attendance

There is a dearth of research examining treatment engagement and attendance among runaway youth and their families. Such research is needed in order to inform treatment providers on factors associated with engagement and maintenance of these difficult to engage families into counseling. This study examined differential treatment attendance for alcohol abusing runaway youth residing at a local shelter. A traditional office-based family systems approach, Functional Family Therapy (FFT), was compared to a non-traditional, home-based, multi-systemic family therapy approach, Ecologically Based Family Therapy (EBFT). As expected, treatment engagement and attendance was significantly higher for those assigned to EBFT (N = 37) compared to FFT (N = 40). Predictors of treatment attendance (income, family chaos, externalization problems and level of youth substance use) were examined within each treatment modality. Findings suggest that home-based (compared to office-based) treatment modalities may significantly increase treatment attendance and engagement of runaway youth and their families. Non-traditional forms of treatment may need to be considered in order to best meet the needs of highly chaotic and disorganized family systems.     

No Worries, No Cares: An Investigation into Self-Reported "Nondistress" in College Students

An important methodological issue in depressionanalog research is whether individuals who scoreextremely low on self-report measures like the BeckDepression Inventory (BDI) should be included innondepressed control groups. Joiner, Schmidt, and Metalsky(1994) found that college students with BDI scores of 0or 1 evidenced a fake-good test taking style as measuredby the MMPI validity scales. The present study investigated whether very low BDI scores (BDI= 0 or 1; n = 21) might be associated with an elevatedpositive mood state, extreme optimism, positiveattributional style or social desirability. Resultsindicated that the very low scoring BDI subjects scoredhigher on social desirability than the low scoring group(BDI = 2 9, n = 63). Significant differences on mood,symptom and cognitive measures disappeared when social desirability was entered as a covariate.Findings support Kendall, Hollon, Beck, Hammen, andIngram's (1987) recommendation that subjects who score0 or 1 on the BDI should be excluded from a nondepressed control group.     

Fatal trio-aplastic anaemia,agranulocytosis and epistaxis

Aplastic anaemia, Agranulocytosis & Epistaxis—when combines in one patient together becomes fatal. Here three case reports are given, all of them suffered from these three diseases simultaneously. All died in spite of best treatment except bone marrow transplantation. It was not done because of non-availability of HLA typing & marrow donor.     

Olfactomotor activity during imagery mimics that during perception

Neural representations created in the absence of external sensory stimuli are referred to as imagery, and such representations may be augmented by reenactment of sensorimotor processes. We measured nasal airflow in human subjects while they imagined sights, sounds and smells, and only during olfactory imagery did subjects spontaneously enact the motor component of olfaction--that is, they sniffed. Moreover, as in perception, imagery of pleasant odors involved larger sniffs than imagery of unpleasant odors, suggesting that the act of sniffing has a functional role in creating of olfactory percepts.     

Craniosynostosis and congenital heart anomalies associated with a maternal deletion of 15q15-22.1

We report an infant with multiple congenital anomalies, including craniosynostosis, tetralogy of Fallot variant, and limb anomalies associated with a maternal deletion of 15q15-22.1. Only two other patients have been reported with a similar deletion, but the deletion was paternal in both cases. We review our patient's findings and compare them to previously reported individuals with similar 15q abnormalities. Our patient allows an expansion of phenotype associated with mid-15q deletions to include severe craniosynostosis, congenital heart disease, and limb anomalies. This will assist in prenatal counseling and predicting postnatal outcome for other affected individuals. The specific breakpoints in our patient and the other patients with similar deletions may also assist in determining a critical region for suture formation.
