Risk models for familial ovarian and breast cancer.

We investigated risk models for the inherited susceptibility of breast and ovarian cancer, using data from both high-risk families and a population based series of ovarian cancer. The first data set consisted of 112 families containing two or more relatives with epithelial ovarian cancer. BRCA1 and BRCA2 germline mutations were detected in 50% of these families.

Transthoracic contrast echocardiographic detection of ascending aortic dissection.

Background: Ascending aortic dissection is highly lethal if left untreated. Therefore rapid accurate diagnosis is necessary. Diagnosis can be made with imaging modalities that use contrast agents to delineate anatomy reliably.

Semirational design of a potent, artificial agonist of fibroblast growth factor receptors.

Fibroblast growth factors (FGFs) are being investigated in human clinical trials as treatments for angina, claudication, and stroke. We designed a molecule structurally unrelated to all FGFs, which potently mimicked basic FGF activity, by combining domains that (1) bind FGF receptors (2) bind heparin, and (3) mediate dimerization. A 26-residue peptide identified by phage display specifically bound FGF receptor (FGFR) 1c extracellular domain but had no homology with FGFs.

The genetic epidemiology of early-onset epithelial ovarian cancer: a population-based study.

We conducted a population-based study to determine the contribution of germline mutations in known candidate genes to ovarian cancer diagnosed at age <30 years. Women with epithelial ovarian cancer were identified through cancer registries. DNA samples were analyzed for mutations in BRCA1, the "ovarian cancer-cluster region" (nucleotides 3139-7069) of BRCA2, and the mismatch-repair genes hMSH2 and hMLH1.

The time course of haemodynamic, autonomic and skeletal muscle metabolic abnormalities following first extensive myocardial infarction in man.

We investigated the time course of genesis of skeletal muscle dysfunction and sympatho-vagal imbalance after myocardial infarction. We studied 22 normal controls, 22 patients with >6 months stable chronic heart failure and 10 patients after a first massive myocardial infarction at 1-3 weeks (the "early" period), 6-8 weeks ("mid") and 6-9 months ("late") following their infarct. Four patients developed overt heart failure.

Screening for breast and ovarian cancer: the relevance of family history.

The recent identification of two breast and ovarian cancer susceptibility genes--BRCA1 and BRCA2--has received a lot of publicity. Public and professional expectations of the availability and utility of genetic testing have been raised and the importance of a family history of breast cancer overemphasized. In this chapter, we examine the significance of a family history of breast or ovarian cancer in determining individual risk.

Self-reported sexual activity and condom use among symptomatic clients attending STD clinics.

Background And Objectives: A cross-sectional survey of sexually transmitted disease (STD) patients assessed sexual activity and condom use during the time between STD symptom onset and clinic attendance.

Study Design: Patients were asked to report sexual activity and condom use while STD symptoms were present. Medical records were abstracted for diagnoses.

Comparison of prophylactic oophorectomy specimens from carriers and noncarriers of a BRCA1 or BRCA2 gene mutation. United Kingdom Coordinating Committee on Cancer Research (UKCCCR) Familial Ovarian Cancer Study Group.

Background: The natural history of ovarian cancer is not well understood and, to date, there is conflicting evidence as to whether or not there is a demonstrable precursor lesion. Some women at high risk of developing ovarian cancer because of their family history elect to have a prophylactic oophorectomy. To determine whether or not a recognizable premalignant lesion could be defined in familial ovarian carcinogenesis, we reviewed ovarian tissue specimens from women whose ovaries were removed prophylactically before gene testing became available and who were tested subsequently for BRCA1 or BRCA2 gene mutations.

Urokinase receptor antagonists: discovery and application to in vivo models of tumor growth.

Urokinase receptor antagonists based on the growth factor domains of both human and murine urokinase which show sub-nanomolar affinities for their homologous receptors have been expressed as recombinant proteins. Further modification of these molecules by preparing fusions with the constant region of human IgG has led to molecules with high affinities and long in vivo half-lives. Smaller peptidic inhibitors have been obtained by a combination of bacteriophage display and peptide analog synthesis.

Effect of endurance exercise training on heart rate variability at rest in healthy young and older men.

Heart rate variability (HRV) (SD of the RR interval), an index of parasympathetic tone, was measured at rest and during exercise in 13 healthy older men (age 60 to 82 years) and 11 healthy young men (age 24 to 32 years) before and after 6 months of aerobic exercise training. Before exercise training, the older subjects had a 47% lower HRV at rest compared with the young subjects (31 +/- 5 ms vs 58 +/- 4 ms, p = 0.0002).

EAA receptors in the dorsomedial hypothalamic area mediate the cardiovascular response to activation of the amygdala.

The role of excitatory amino acid (EAA) receptors in the dorsomedial hypothalamus (DMH) in mediating the cardiovascular response to activation of the basolateral amygdala (BLA) was examined using conscious rats. Microinjection of the nonselective EAA receptor antagonist kynurenic acid (0.1-10 nmol) into the DMH blocked or reversed the increases in heart rate and arterial pressure resulting from injection of the GABAA receptor antagonists bicuculline methiodide (BMI; 100 pmol) and picrotoxin (100 pmol) into the BLA.

High cell-density fermentation.

The purpose of this chapter is to educate the reader about the basic equipment and strategies used in fermentations of P. pastoris in both bench-top and pilot-scale operations. A key element in expression of foreign proteins in this yeast is the need for sufficient aeration, which is achieved by proper mixing of the media and by blending gases to control dissolved oxygen content.

A systematic review and meta-analysis of family history and risk of ovarian cancer.

Objective: To estimate the relative risk and lifetime risk of ovarian cancer in women with various categories of family history.

Design: A meta-analysis of all published case-control and cohort studies.

Methods: Pooled relative risk estimates were calculated for the case control studies, using the Mantel-Haenzel method.

A new approach to substance abuse treatment. Adolescents and adults with ADHD.

Adolescents and young adults with Attention Deficit Hyperactivity Disorder (ADHD) are not only at risk for drug and alcohol dependence, but are also difficult to maintain in a chemical dependency facility due to disruptive behaviors. Such patients may be "hyperaroused," a term coined by the field of occupational therapy, but oppositional behaviors hide their physical and emotional overreactivity. Thirty years ago, occupational therapist Dr.

Rectal prolapse associated with bulimia nervosa: report of seven cases.

Purpose: Rectal prolapse is a condition in which, when complete, the full thickness of the rectal wall protrudes through the anus. Bulimia nervosa is an eating disorder characterized by periodic food binges, which are followed by purging. Purging usually takes the form of self-induced vomiting, laxative abuse, and/or diuretic abuse.

Fate of gelatin-resorcinol-formaldehyde/glutaraldeyde adhesive on femoral vessel morphology.

Several clinical reports have demonstrated that gelatin-resorcinol-formaldehyde/glutaraldehyde (GRFG) glue can be useful in the repair of acute aortic dissection; however, the cellular and extracellular events that follow GRFG application, as well as the mechanisms responsible for the long-term strength and adhesive properties of GRFG, remain unclear. Accordingly, the present study examined the long-term effects of GRFG adhesive application on femoral vessel extracellular structure and composition. The left and right femoral artery and vein were sterilely exposed in adult rats, and GRFG (2 mL) was applied between and around one pair of vessels.

Self-treatment patterns among clients attending sexually transmitted disease clinics and the effects of self-treatment on STD symptom duration. The Study Group.

Objective: To assess patterns of self-treatment and its effects on the duration of sexually transmitted disease (STD) symptoms before medical care.

Methods: A cross-sectional interview survey in public STD clinics (7 U.S.

Contribution of BRCA1 mutations to ovarian cancer.

Background: Inherited mutations in the BRCA1 gene confer a high risk of breast and ovarian cancer in some families. To determine the contribution of BRCA1 mutations to ovarian cancer in the general population, we analyzed DNA samples from a consecutive series of women with ovarian cancer seen at one center.

Methods: We studied 374 women who received a diagnosis of epithelial ovarian cancer before the age of 70 years and were treated at the Royal Marsden Hospital between July 1993 and September 1995.
