Electronic job searching : suggestions for educators

The Internet offers an abundance of resources and information to the job seeker. Because of this great wealth of data, it is important educators are able to assist students in developing a path to take when utilizing the Internet as a job searching tool. When job searching using the Internet, students can go online to determine their interests, research various careers, research various companies, and research general and specific job listings using online job boards and online newspaper classifieds. The Internet also offers information on the various resume formats needed by today\u27s job seeker. These resume formats include those that are scannable, searchable and uploadable along with resumes that are Web based and those that are input via the use of forms located at various Internet job boards. Some types of projects educators could use include developing keyword lists, web site address lists, networking skills, digital portfolios and job search notebooks. Overall, educators today need to develop projects that help students become familiar with both traditional as well as electronic methods of job seeking

Rapid and sensitive detection of CpG-methylation using methyl-binding (MB)-PCR

Methylation of CpG islands is associated with transcriptional repression and, in cancer, leads to the abnormal silencing of tumor suppressor genes. We have developed a novel technique for detecting CpG-methylated DNA termed methyl-binding (MB)-PCR. This technique utilizes a recombinant protein with high affinity for CpG-methylated DNA that is coated onto the walls of a PCR vessel and selectively captures methylated DNA fragments from a mixture of genomic DNA. The retention and, hence, the degree of methylation of a specific DNA fragment (e.g. a CpG island promoter of a specific gene) is detected in the same tube by gene-specific PCR. MB-PCR does not require bisulfite treatment or methylation-sensitive restriction and provides a quick, simple and extremely sensitive technique allowing the detection of methylated DNA, in particular in tumor tissue or tumor cells from limited samples. Using this novel approach, we determined the methylation status of several established and candidate tumor suppressor genes and identified the ICSBP gene, encoding the myeloid and B-cell-specific transcription factor interferon consensus sequence-binding protein, as a target for aberrant hypermethylation in acute myeloid leukemia

C-reactive Protein in Patients with Metastatic Clear Cell Renal Carcinoma: An Important Biomarker for Tumor-associated Inflammation

Two consecutive multi-center phase II trials were designed to prove the hypothesis, whether therapeutic modeling of tumor-associated inflammatory processes could result in improved tumor response

The enrichment of an alkaliphilic biofilm consortia capable of the anaerobic degradation of isosaccharinic acid from cellulosic materials incubated within an anthropogenic, hyperalkaline environment.

Anthropogenic hyper-alkaline sites provide an environment that is analogous to proposed cementitious geological disposal facilities (GDF) for radioactive waste. Under anoxic, alkaline conditions cellulosic wastes will hydrolyse to a range of cellulose degradation products (CDP) dominated by isosaccharinic acids (ISA). In order to investigate the potential for microbial activity in a cementitious GDF, cellulose samples were incubated in the alkaline (∼pH 12), anaerobic zone of a lime kiln waste site. Following retrieval, these samples had undergone partial alkaline hydrolysis and were colonised by a Clostridia dominated biofilm community, where hydrogenotrophic, alkaliphilic methanogens were also present. When these samples were used to establish an alkaline CDP fed microcosm, the community shifted away from Clostridia, methanogens became undetectable and a flocculate community dominated by Alishewanella sp. established. These flocs were composed of bacteria embedded in polysaccharides and protein stabilised by extracellular DNA. This community was able to degrade all forms of ISA with >60% of the carbon flow being channelled into extracellular polymeric substance (EPS) production. This study demonstrated that alkaliphilic microbial communities can degrade the CDP associated with some radioactive waste disposal concepts at pH 11. These communities divert significant amounts of degradable carbon to EPS formation, suggesting that EPS has a central role in the protection of these communities from hyper-alkaline conditions

The Impact of a Tumor Diagnosis on Patients' Attitudes toward Advance Directives

Background: Although advance care planning and the completion of advance directives (ADs) are important tools to avoid unwanted aggressive care once patients have lost their decision-making capacity, only a minority of cancer patients are admitted with completed ADs, and little is known about patients' wishes regarding AD consultations. Methods: For 1 year, every new patient admitted to the hematology/oncology outpatient clinic of the University Hospital Regensburg received a self-administered questionnaire comprising a self-evaluation of AD knowledge and questions about preferences regarding consultation partners and the time of consultation. Disease-related data were collected from medical records. Statistics were calculated with SPSS. Results: Of the 500 questionnaires handed out, 394 (75%) were evaluable and analyzed. Twenty-eight percent of the participants had completed an AD (living will or health care proxy). Ninety-two percent of the participants without ADs had never received a consultation offer from any professional involved. Only 20% perceived a clear relation between cancer and AD consultations. More than 50% of the participants without ADs were in favor of consultations ‘now' or ‘in a few weeks', while more than 40% objected to AD consultations. Conclusions: Oncology patients have a large unmet demand for AD consultations. However, a relevant percentage of these patients object to AD consultations. Structured and early AD consultation offers should be made, and early discussions about indications for aggressive treatment should take place

Prophylactic Application of Nebulized Liposomal Amphotericin B in Hematologic Patients with Neutropenia

Background: Pulmonary invasive fungal infections (IFI) are well-recognized complications with high morbiditiy and mortality in patients with hematologic malignancies. Patients and Methods: Aerosolized liposomal amphotericin B (lipAmB) was evaluated as an antifungal prophylaxis in patients with an expected neutropenia of more than 10 days due to intensive chemotherapy or stem cell transplantation, in a prospective phase II trial. Results: 98 treatment episodes were included in the study and compared to 105 historical control patients. Inhalation was performed between 0 and 103 days. No severe side effects of therapy occurred. 40 patients considered inhalations as unpleasant, 2 as very unpleasant, mostly due to bad taste or cough. Few cases of definite or probable IFI were recorded, whereas a large number of patients were treated with systemic antifungal therapy for pneumonia or fever of unknown origin without a significant difference between study patients and controls. In a predefined subgroup analysis of 48 patients with newly diagnosed acute myeloid leukemia (AML), significantly more patients survived for 1 year in the AmB prophylaxis than in the control group (80% vs. 54%, p < 0.01). Conclusions: Inhalations of lipAmB are feasible and safe. Results in the subgroup of patients with AML together with data from other trials suggest further evaluation of effectiveness
