Objective: Conduct a needs assessment to explore the experiences, barriers, and needs of genetic counselors (GCs), who counsel and refer young and metastatic breast cancer (BC) patients to support services, in order to develop resources to address any noticeable gaps.
Methods: GCs providing care to BC patients were eligible to complete the survey. Support services were defined as resources to address patient-centered healthcare, emotional, and quality-of-life needs.
Purpose: To evaluate timing and outcomes of BRCA testing and definitive surgical treatment among patients with newly diagnosed breast cancer.
Methods: Patient-reported (n = 1,381) and deidentified health-plan (n = 2,369) data were analyzed from a consecutive national series of 3,750 women whose healthcare providers ordered BRCA testing between March 2014 and June 2015, within 1 year following breast cancer diagnosis.
Results: Among 1,209 respondents, 54.
Genome-wide studies of gene expression and transcription factor-binding sites using DNA microarrays are leading to new systems level insights. The massively parallel nature of microarrays presents technical challenges: fabricating high-quality microarrays at the front end and data analysis and interpretation downstream. A principal challenge in fabricating microarrays is preparation of the DNA samples.

These ribozymes are usually designed with four basepairs in helix II, and with equal numbers of nucleotides in the 5' and 3' hybridizing arms that bind the RNA substrate on either side of the cleavage site. Here guidelines are given for redesigning the ribozyme so that it is small, but retains efficient cleavage activity.
View Article and Find Full Text PDFA general study has been carried out to determine how well hammerhead ribozymes might reduce levels of specific protein synthesis in living cells, compared with RNA hairpin loops as stable but noncleaving controls. Four different experiments are described. First, a wide variety of hammerhead ribozymes, as well as hairpin loops, was cloned into a gene-expression cassette for beta-galactosidase, upstream of the coding sequences for that reporter gene, and expressed from plasmids in several strains of Escherichia coli.

The starting population (g0) was directed in trans against an RNA oligonucleotide substrate immobilised to an avidin-magnetic phase. Four rounds of selection were conducted using 20 mM Mg2+to fractionate the population on the basis of divalent metal ion-dependent phosphodiesterase activity.

Fourteen total wrist arthroplasties performed in 13 patients with rheumatoid arthritis between 1978 and 1982 were reviewed to evaluate long term outcome. Most patients had Stages III or IV rheumatoid arthritis at the time of surgery. Pain was the primary presenting complaint in 87%.

Using the techniques of reverse transcriptase-polymerase chain reaction (RT-PCR) and protein isoelectric focusing (IEF) we have shown this processed gene to be fully functional, but liver specific. In contrast, the unprocessed X-linked parent gene HPRT-1 was expressed in all somatic tissues.

Approaches used on the Medical Ward of the Clinical Institute of the Addiction Research Foundation (ARF) are presented. The attitude of the physiotherapist toward addictions is important, both in the rehabilitation of the patient's physical problem and in the treatment of his/her alcohol or drug problem.

Six patients had solid femoral head allografts and the others, morselized allografts. Radiographs at 2-year follow up showed an average of 8 mm of superior migration and 4 mm of medial migration.

Experimental conditions and inhibitor profils studies suggest neutral metalloproteinases induce the autolysis. In these preliminary studies we compared the degradation of Na2 35SO4 labeled bovine nasal cartilage (BNC) plugs placed in dialysis tubing in vitro and in vivo.

Chondrocytes obtained from rat articular cartilage and Swarm rat chondrosarcoma were maintained in culture. Human interleukin-1 (IL-1) was added at confluency, and three days later the spent media was evaluated for proteoglycan- and collagen-degrading enzymes. Unlike chondrocytes from articular cartilage from several species, chondrocytes from Swarm rat chondrosarcoma did not respond to IL-1 stimulation.

The bronchodilatory effect of histamine was evaluated in a conscious guinea-pig model of cholinergically mediated bronchoconstriction. The H1, bronchoconstrictor, property of histamine was masked using high doses of the H1-antagonist chlorpheniramine (30 mg/kg), and the bronchodilatory activity evaluated by observing the increase in latency to collapse induced by aerosol methacholine. Under these conditions, histamine (1.

We studied the cases of eighty-one patients (108 total hip arthroplasties), ranging in age from fourteen to forty-five years, at an average of 4.5 years after the index operation and evaluated them with regard to six major factors: age, disease, Charnley category, prior operations, length of time since arthroplasty, and quality of the arthroplasty with regard to cementing technique and component position. After two to five years 78 per cent were satisfactory, but after five years or more only 72 per cent were satisfactory.
