Notes on a Sapphirina and a Salpa caught off the Cape of Good Hope

When I captured these animals I was a passenger on board the ship Invercargill, Captain John Muir, then on a voyage from London to Port Chalmers, N.Z. Nothing unusual was noticed in the appearance of the sea, which was calm, until the afternoon, when the water was filled with brilliant blue stars, floating past the ship in great numbers. With a small canvas bag I succeeded in fishing up several of the blue stars, which were a species of Sapphirina, and two or three other animals, non-luminous, one of which was a Salpa democratica. I kept them in a glass of sea water till the 29th, when an unfortunate accident killed them, and having only a small magnifying glass, I was prevented from making a full examination of all. I preserved the sketches I was able to make, and through the kindness of Mr. Morton, of the Royal Society's Museum, I lately received from Mr. Haswell, of Sydney, information as to the species and construction of the animals depicted. The two small crustaceans correspond so closely with the descriptions and drawings of the male and female of Sapphirina gemma, as given by J. D. Dana ("Crustacea," Part II., pp. 1252-3; Atlas, Plate 88, figs. 1 and 2), that I am very confident that they are individuals of that species. I have not been able to find any detailed account of the Salpae in the Society's Library, but in the Proceedings of the Boston Society of Natural History, Vol. XI., p. 17, is a detailed description, with woodcuts, of Salpa Cabotti, by Alexr. Agassiz. This is found south of Cape Cod, and very closely resembles the one I caught, and the description and investigation into the connection of the chain forms are highly interesting.

dissertationThis investigation sought to determine if a nursing intervention with first degree relatives (children, siblings, parents, and spouses) of victims of sudden cardiac death would promote change in high risk behaviors for coronary heart disease. The Nursing; intervention strategy was designed to assess, inform/educate and provide emotional support regarding familial/genetic risk factors, cardiovascular behavioral risk factors, and health beliefs. The study design was a two group experimental design using repeated measures of health beliefs and health behaviors with random assignment of subjects into groups. The sample consisted of 58 first degree relatives of sudden death victims referred for autopsy by the County Coroner. The outcome measures included changes in health beliefs, health behaviors and whether or not subjects elected screening for blood pressure and serum cholesterol. Approximately 65%, or 12 of 16 families demonstrated familial aggregation of cardiac diseases. Analysis of covariance was used to determine health behavior, health beliefs, and knowledge differences between groups on health beliefs. There were significant differences between sibling groups on how susceptible they reported their children to be to cardiac disease and how serious they perceived cardiac disease to be. Health habit differences included significant reductions in the experimental group on alcohol and meat consumption. There were no statistically significant group differences on knowledge, although the experimental group increased in knowledge while the control remained the same. Seventy-six percent of the experimental group did have blood pressure screening compared to 57% in the control. In the experimental group, 27% had serum cholesterol screening compared to 14% of the control group. Qualitative data were collected on the events leading to death for the sudden death victim, risk factors associated with sudden death, and the family member's perceptions of sudden cardiac death. Nursing intervention made a difference for experimental siblings (the highest risk group) on health beliefs (increased perceived susceptibility and severity) health behaviors (alcohol and meat consumption) and screening for blood pressure and serum cholesterol. Primary preventive intervention holds promise for reduction of cardiovascular mortality

thesisAn attempt was made to isolate secretory component from the molecule secretory Immunoglobulin A. Two methods were used, each with colostrum as the source of secretory component. In the first method, colostrum was centrifuged, and the supernatant was chromatographed on a Sephadex G-200 column. Half of the eluates were concentrated by negative pressure dialysis, and half of the eluates were chromatographed on a carboxymethyl-50 cation exchange column. All eluates collected were subjected to Immunoelectrophoresis. In the second method the colostrum was clarified, and the proteins were precipitated by the addition of ammonium sulfate. The eluates were chromatographed on a DEAE cellulose column using a stepwise elution of three sodium phosphate buffers. Further chromatography included a GM-50 cation exchange column and identification of the proteins by the method of Ouchterlony using rabbit antiserum against secretory IgA. Free or unattached secretory component was found in the second elution peaks from the Sephadex G-200 gel filtration column and from the first fraction of colostral whey eluted using O.OIM sodium phosphate buffer, at pH 7.6. Secretory component was highly contaminated with lactoferrln and was not obtained In a pure state. Failure to obtain spurring between second peak eluates and antl S-IgA could be the result of differences in quarternary structure between the tetramerlc free form and the IgA bound form

A three dimensional analysis of soft tissue and bone changes following orthognathic surgery

Introduction: This report investigates the ability of surgeons to achieve predicted surgical movements in five different groups of patients, and analyses both the predictions and the changes in two dimensions using scale space analyses (Campos 1991). The report then progresses to the three dimensional analysis of the bone, the soft tissues and the ratio of soft tissue to bone following surgery, using a colour coded techniques (Fright and Linney, 1991) to illustrate the changes. The average soft tissue scans from each group of patients were averaged and compared to a control group at the preoperative, three months and 1 year postoperative stages (Fright, 1991) Data Acquisition: Bone measurements were recorded from lateral skull radiographs preoperatively and 48 hrs postoperatively, and CT scans preoperatively and 1 year postoperatively. Soft tissue measurements from an optical scanner, preoperatively, three months and 1 year postoperatively. Patients 1) Control group: 30 females and 30 males 2) Skeletal class 2 patients: 15 Females and 2 Males 3) Skeletal class 3 patients: 9 Females and 7 Males 4) Cleft Palate Patients a) Unilateral cleft lip and palate: I 6 Females: 2 left and 4 right sided clefts 7 Males: 3 left and 4 right sided clefts b) Bilateral cleft lip and palate: 5 Males and 1 Female c) Clefts of the Hard and Soft palate: 5 Females. Results: Prediction: There was a surprisingly poor match between the predicted and achieved movements in both the horizontal and vertical direction in all patient groups. The scale space analysis provided an efficient method of illustrating profile changes. Soft tissue movements There were definite patterns of change and relapse in the patient groups. The relapse being most marked in the cleft palate patients. Bone movements and soft tissue to bone ratios Definite patterns of movement for the maxilla and the mandible became apparent for both the bone and soft tissue to bone ratio of movement in each group. For maxillary impactions in the skeletal 2 group there was a 1:1 ratio of movement of the soft tissue to bone in the midline increasing to 1.25:1 in the canine region and 1.5:1 in the paranasal region. Conclusions: There is a need to develop a technique to aid the the surgeons in carrying out planned surgical movements. The colour coded method was shown to be a simple, efficient and easily understandable way of analysing surgical change. Diagnosis of surgical requirements was aided by the ability to objectively compare the individual to a control group. The prediction of surgical change should be greatly aided by adapting the current database to include the distinct patterns of movement in the bone and ratio of movements of the soft tissues to the bone

Emotional labor in intercultural service encounters: An experience sampling study

The body of literature surrounding emotional labor, defined as service employees??? effort to manage their emotions to meet organizational goals (Hochschild, 1983; Morris & Feldman, 1996), exhibits a severe lack of studies examining intercultural service encounters (i.e., service episodes in which a provider from culture A delivers a service to a customer from culture B; Stauss & Mang, 1999). This dissertation posits an intrapersonal model of emotional labor in intercultural service encounters. Central to this model is the construct of cultural competence (Earley & Ang, 2003), which is defined as the ability to adapt effectively and flexibly in culturally diverse settings. Using experience sampling methodology with a hospitality industry sample, I found that cultural competence was associated with deep acting and performance. Openness to experience predicted cultural competence through active seeking of multicultural experience (i.e., multicultural personality). Implications for the selection (based on openness) and training (for deep acting and cultural competence) of service providers in an increasingly globalized service industry are discussed

Methadone, Buprenorphine, and Street Drug Interactions with Antiretroviral Medications

While street drugs appear unlikely to alter the metabolism of antiretroviral (ARV) medications, several ARVs may induce or inhibit metabolism of various street drugs. However, research on these interactions is limited. Case reports have documented life-threatening overdoses of ecstasy and gamma-hydroxybutyrate after starting ritonavir, an ARV that inhibits several metabolic enzymes. For opioid addiction, methadone or buprenorphine are the treatments of choice. Because a number of ARVs decrease or increase methadone levels, patients should be monitored for methadone withdrawal or toxicity when they start or stop ARVs. Most ARVs do not cause buprenorphine withdrawal or toxicity, even if they alter buprenorphine levels, with rare exceptions to date including atazanavir/ritonavir associated with significant increases in buprenorphine and adverse events related to sedation and mental status changes in some cases. There are newer medications yet to be studied with methadone or buprenorphine. Further, there are many frequently used medications in treatment of complications of HIV disease that have not been studied. There is need for continuing research to define these drug interactions and their clinical significance
