Expression Of G-Protein Inwardly Rectifying Potassium Channels (Girks) In Lung Cancer Cell Lines, Howard Plummer 3rd, Madhu Dhar, Maria Cekanova Ms, Rndr, Phd, Hildegard Schuller

Maria Cekanova MS, RNDr, PhD

BACKGROUND: Previous data from our laboratory has indicated that there is a functional link between the beta-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in human breast cancer cell lines. We wanted to determine if GIRK channels were expressed in lung cancers and if a similar link exists in lung cancer. METHODS: GIRK1-4 expression and levels were determined by reverse transcription polymerase chain reaction (RT-PCR) and real-time PCR. GIRK protein levels were determined by western blots and cell proliferation was determined by a 5-bromo-2'-deoxyuridine (BrdU) assay. RESULTS: GIRK1 mRNA was expressed in three of six small …

How Well Can Signs And Symptoms Predict Ami In The Malaysian Population?, Awang Bulgiba

Awang Bulgiba Awang Mahmud

The aim of the study was to use data from an electronic medical record system (EMR) to look for factors that would help us diagnose acute myocardial infarction (AMT) with the ultimate aim of using these factors in a decision support system for chest pain. We extracted 887 records from the electronic medical record system (EMR) in Selayang Hospital, Malaysia. We cleaned the data, extracted 69 possible variables and performed univariate and multivariate analysis. From the univariate analysis we find that 22 variables are significantly associated with a diagnosis of AMT. However, multiple logistic regression reveals that only 9 of …

Higher Burden Of Hemorrhagic Stroke Among Women An Autopsy-Based Study In São Paulo, Brazil, Paulo A. Lotufo

Paulo A Lotufo

The aim of this study was to verify the gender difference in sudden cardiovascular death, mainly comparing brain infarction and hemorrhagic stroke. We analyzed 970 autopsy cases from a total of 3,802 nonviolent deaths (448 considered as sudden deaths, 296 undetermined, and 226 non-sudden deaths) including patients aged 30–69 years. All cardiovascular diseases were responsible for 69% of sudden deaths, and all types of stroke for only 14%. The proportions of sudden death for all cardiovascular diseases, coronary heart disease and ischemic stroke deaths were similar for both sexes. However, sudden deaths due to all types of stroke (women 20.0%; …

Stroke In Brazil: A Neglected Disease, Paulo A. Lotufo

Paulo A Lotufo

The turning point in the transition from infectious diseases to non-transmittable diseases in Brazil occurred in the 1960s, taking the country as a whole. However, considering the main cities, such as São Paulo and Rio de Janeiro, cerebrovascular disease mortality rates have surpassed the “old cardiovascular diseases” like rheumatic heart disease and syphilitic aortic disease since the end of World War II. Until the end of the 1980s, the burden of stroke mortality observed in the main Brazilian cities was higher than in the United States, Canada and western European countries, and similar to what is observed in Eastern Europe …

Trends Of Stroke Subtypes Mortality In Sao Paulo, Brazil (1996-2003), Paulo A. Lotufo, Isabela M. Bensenor

Paulo A Lotufo

The decline of stroke mortality rates has been described in Brazil; however, there is no data about stroke subtypes. We described the changes of stroke mortality rates in the city of Sao Paulo (1996-2003) emphasizing intracerebral hemorrhage and cerebral infarction. We categorized mortality data by gender and 10-year age-strata from 30 to 79 years-old. For men, an annual reduction of all types of stroke (-3.9%), and of stroke subtypes as intracerebral hemorrhage (-3.0%) and cerebral infarction was observ e d (-2.7%) as well as, a decline of ill-defined stroke (-7.4%). For women, a decline was observed for all types of …

Progress Testing: Evaluation Of Four Years Of Application In The School Of Medicine, University Of São Paulo, Paulo A. Lotufo

Paulo A Lotufo

Progress testing is a longitudinal tool for evaluating knowledge gains during the medical school years. Objectives: (1) To implement progress testing as a form of routine evaluation; (2) to verify whether cognitive gain is a continuous variable or not; and (3) to evaluate whether there is loss of knowledge relating to basic sciences in the final years of medical school. Methods: A progress test was applied twice a year to all students from 2001 to 2004. The mean percentage score was calculated for each school year, employing ANOVA with post hoc Bonferroni test evaluation for each test. Results:Progress testing was …
