The rise and fall of the Synthetic: The mediatization of Canada's oil sands.

The concept of the Synthetic is developed to trace and trouble the prevailing popular mythology of Alberta's oil sands and place the omnipresence of petro-hegemony into focus in a time of crisis and transition. The Synthetic is theorized as a period of petroculture beginning in the late 1960s with the rise of Alberta's oil sands industry together with a rise in oil sands narratives, docudrama, and the emergence of mediated or synthetic politics reliant upon processed images. Attention focuses on three mediated moments within the Synthetic beginning with the banned 1977 CBC docudrama and the reaction of Premier Peter Lougheed.

Storm sampling to assess inclement weather impacts on water quality in a karst watershed: Sinking Creek, Watauga watershed, East Tennessee.

Sinking Creek (HUC 06010103046), in the Watauga watershed of northeast Tennessee, is impaired due to Escherichia coli. To assess how E. coli and other water quality parameters fluctuated during storm events, water samples were collected with automated samplers during eight storms at two locations: Sinking Creek and a feeder spring.

No Surrender. No Challenge. No Protest Paradigm: A Content Analysis of the Canadian News Media Coverage of the "Yellow Vest Movement" and the "United We Roll Convoy".

This study's exhaustive content analysis (N = 538) examines how Canada's mainstream news media covered the nascent yellow vest movement from the first Canadian protests in December 2018 culminating in the February 2019 cross-country United We Roll convoy. We demonstrate that Protest Paradigm scholarship does not offer a useful analytic for understanding the coverage of this right-wing social movement whose tactics were banal and law abiding. Furthermore, we argue that Canadian news media coverage of the protest movement was largely uncritical and decidedly hegemonic, raising questions about normative watchdog conceptions of the news media in Canadian democracy.

Metal Adsorption Controls Stability of Layered Manganese Oxides.

Hexagonal birnessite, a typical layered Mn oxide (LMO), can adsorb and oxidize Mn(II) and thereby transform to Mn(III)-rich hexagonal birnessite, triclinic birnessite, or tunneled Mn oxides (TMOs), remarkably changing the environmental behavior of Mn oxides. We have determined the effects of coexisting cations on the transformation by incubating Mn(II)-bearing δ-MnO at pH 8 under anoxic conditions for 25 d (dissolved Mn < 11 μM). In the Li, Na, and K chloride solutions, the Mn(II)-bearing δ-MnO first transforms to Mn(III)-rich δ-MnO or triclinic birnessite (T-bir) due to the Mn(II)-Mn(IV) comproportionation, most of which eventually transform to a 4 × 4 TMO.

Acute lymphoblastic leukemia in a pygmy hippopotamus (Hexaprotodon liberiensis).

A captive, 31-yr-old, intact male pygmy hippopotamus presented with nonspecific signs of weight loss, inappetence, diarrhea, and lethargy. After 5 wk of diagnostic investigation and symptomatic treatment, an acute leukemic process with concurrent polycystic kidney disease was suspected. The animal's condition continued to deteriorate prompting euthanasia.

Use of sentinel sites for daily monitoring of the US blood supply.

Background: This report describes the first year of a government-sponsored program that uses daily reports from 29 sentinel sites to monitor the capacity of the US blood supply to meet demand.

Study Design And Methods: From August 15, 2001, to August 14, 2002, 29 sentinel sites provided daily reports of the number of units of RBCs in inventory, transfused, exported, and outdated by ABO and Rh, and platelets by random or apheresis donor. Days supply of each component category was calculated as the number of units in inventory reported on a day divided by the sum of units transfused, exported, and outdated on that day.

Prevalence, donation practices, and risk assessment of blood donors with hemochromatosis.

Context: Despite changes in eligibility policies, practical barriers limit blood donations from individuals with hemochromatosis. Increased knowledge of hemochromatosis donor characteristics may help foster further changes that will promote more donations.

Objectives: To estimate the prevalence of donors diagnosed as having hemochromatosis and to compare rates of unreported deferrable risks for transfusion-transmissible viral infections (TTVIs), positive screening test results for TTVIs, and donation patterns between hemochromatosis patient donors and donors reporting no medical conditions necessitating phlebotomy (non-health-related donors).

Absence of human T-lymphotropic virus type I tax sequences in a population of normal blood donors in the Baltimore, MD/Washington, DC, area: results from a multicenter study.

Background: It was reported recently that sequences corresponding to the human T-lymphotropic virus type I (HTLV-I) tax gene were detected in peripheral blood mononuclear cells from 8 to 11 percent of healthy blood donors without detectable antibodies to HTLV-I. A multicenter blind study was conducted to determine if these results could be independently confirmed.

Study Design And Methods: Specimens were collected from 100 anti-HTLV-I-negative healthy blood donors and from 11 anti-HTLV-I- or anti-HTLV-II-positive individuals.

Cord Blood Transplantation Study (COBLT): cord blood bank standard operating procedures.

In 1995, the National Heart Lung and Blood Institute (NHLBI) solicited requests for a proposal (RFP) entitled "Transplant Centers for Clinical Research on Transplantation of Umbilical Cord Stem and Progenitor Cells." Three banks, six transplant centers, and one medical coordinating center (MCC) (Table 1) were funded with the overall goal of banking cord blood units (CBU) using a single manual of operations. Furthermore, the clinical protocols to evaluate the transplant outcome for adult and pediatric recipients of these well-characterized CBU would be analyzed in a uniform fashion.

Hemolysis in sickle cell disease as measured by endogenous carbon monoxide production. A preliminary report.

To detect and quantitate temporal variations of the hemolytic rate in sickle cell disease, the authors measured endogenous carbon monoxide (CO) production in five normal subjects, nine patients with sickle cell anemia (SS) in steady clinical state, and two patients with sickle cell-hemoglobin C (SC) disease in and out of pain crises. The red blood cell life span calculated from these data (RCLSco) ranged from 81.2 to 102.

Complications related to equipment and technique.

Automated cytapheresis, when performed by experienced operators using modern equipment, is remarkably free of adverse effects. A declining pattern of equipment failure and related problems has been recorded in the 220,000 procedures performed by the American Red Cross in the past 5 years. Other cytapheresis centers report similar findings.

Chronic lymphocytic leukemia: a monoclonal disease.

A black woman with chronic lymphocytic leukemia (CLL) was found to have monoclonal B lymphocytes with one type of surface immunoglobulin and one variant of G6PD (glucose-6-phosphate dehydrogenase) (G6PD A). Erythrocytes and T cells contained both G6PD A and G6PD B and hence were of polyclonal origin. The CLL cells in this patient likely arose from a developmental stage later than the step of differentiation into T and B lymphocytes.

Oat cell carcinoma mimicking leukemia.

A patient with oat cell carcinoma had circulating carcinoma cells, which initially suggested a diagnosis of acute leukemia. The correct diagnosis was made only by histopathologic examination of the bone marrow. A case of a similar bone marrow disorder, which developed after diagnosis of oat cell carcinoma, is also presented.

Screening for abnormal hemoglobins: who, when, and how.

Sickle cell and abnormal hemoglobin screening programs should not be undertaken lightly but rather should have a specific purpose or purposes. If the aim is to detect only sickle hemoglobin, a certain strategy is necessary. If the goal is to detect all abnormal hemoglobins and genetic counseling is planned, another approach should be used.

Cholelithiasis in sickle cell anemia: a case for elective cholecystectomy.

Ten patients with sickle cell anemia over the age of 10 who had cholecystectomy are reported. All had symptomatic cholecystitis; three had biliary tract obstruction. Transfusions were given preoperatively and with attention to oxygenation and fluid and electrolyte balance.

Proton nuclear magnetic resonance studies of hemoglobin Providence (beta82EF6 Lys replaced by Asn or Asp): a residue involved in anion binding.

High-resolution proton nuclear magnetic resonance studies of hemoglobins Providence-Asn (beta82EF6 Lys replaced by Asn) and Providence-Asp (beta82EF6 Lys replaced by Asp) show that different amino acid substitutions at the same position in the hemoglobin molecule have different effects on the structure of the protein molecule. Hemoglobin Providence-Asp appears to be in a low-affinity tertiary structure in both the deoxy and carbonmonoxy forms. Deoxyhemoglobin Providence-Asn has its beta heme resonance shifted downfield slightly from its position in normal adult hemoglobin; however, the tertiary structures of the heme pocket of hemoglobins A and Providence-Asn are very similar when both proteins are in the carbonmonoxy form.

Delayed hemolytic transfusion reactions. An often-missed entity.

Delayed hemolytic transfusion reactions in eight persons were manifested solely or primarily by an apparently unexplained posttransfusion decrease in the hematocrit value. Alloantibodies were eventually found in all eight patients, but were sometimes undetectable for as long as 72 hours after the reaction. This did not preclude the occurrence of a new, acute hemolytic reaction.

Irreversibly sickled cells and red cell survival in sickle cell anemia: a study with both DF32P and 51CR.

For 25 subjects with sickle cell anemia the mean red cell life span measured with Di-isopropylfluorophosphite-32P (DF32P) was 17.32 +/- 4.51 days.
