Serum is free of cellular components. Because DNA is located in the nuclei or mitochondria of cells, serum could be assumed DNA free. Few previously published case reports to date have used serum for DNA typing. Here, we report on human genotyping via short tandem repeat (STR) analysis using serum as a sample, and discuss problems involved in the process.

5.Effect of Crowding and Nurse Staffing on Time to Antibiotic Administration for Patients with Pneumonia in an Emergency Department
Journal of Korean Academy of Nursing Administration 2018;24(2):107-117
PURPOSE: This study was conducted to identify the effect of crowding and nurse staffing on time to antibiotic administration for pneumonia patients in an emergency department (ED). METHODS: The sample included pneumonia patients visiting an ED from November 1, 2014 to February 28, 2015. Crowding was measured using ED occupancy rate, nurse staffing was measured as total length of stay per nurse and number of patients per nurse and the time duration was measured for the following processes: from patient arrival to prescription, from prescription to blood culture and antibiotic administration, and from blood culture to antibiotic administration. Data collected from the electronic medical records were analyzed using multivariate analyses. RESULTS: The mean times from arrival to antibiotics administration, from prescription to antibiotic administration, and from blood culture to antibiotic administration were 128.31, 47.29, and 15.60 minutes, respectively. Crowding, nurse staffing, work experience of the nurse and severity of the patient influenced the time duration of each process from patient arrival to antibiotic administration. CONCLUSION: The results reveal that crowding and nurse staffing affect length of time to antibiotic administration in pneumonia patients. Guidelines for safe nurse staffing in ED are required to improve patient outcomes.

Layer 2/3 pyramidal neurons (L2/3 PyNs) of the cortex extend their basal dendrites near the soma and as apical dendritic tufts in layer 1, which mainly receive feedforward and feedback inputs, respectively. It is suggested that neuromodulators such as serotonin and acetylcholine may regulate the information flow between brain structures depending on the brain state. However, little is known about the dendritic compartment-specific induction of synaptic transmission in single PyNs.Here, we studied layer-specific serotonergic and cholinergic induction of long-term synaptic plasticity in L2/3 PyNs of the agranular insular cortex, a lateral component of the orbitofrontal cortex. Using FM1-43 dye unloading, we verified that local electrical stimulation to layers 1 (L1) and 3 (L3) activated axon terminals mostly located in L1 and perisomatic area (L2/3). Independent and AMPA receptor-mediated excitatory postsynaptic potential was evoked by local electrical stimulation of either L1 or L3. Application of serotonin (5-HT, 10 μM) induced activity-dependent longterm depression (LTD) in L2/3 but not in L1 inputs. LTD induced by 5-HT was blocked by the 5-HT2 receptor antagonist ketanserin, an NMDA receptor antagonist and by intracellular Ca2+ chelation. The 5-HT2 receptor agonist α-me-5-HT mimicked the LTD induced by 5-HT. However, the application of carbachol induced muscarinic receptor-dependent LTD in both inputs. The differential layer-specific induction of LTD by neuromodulators might play an important role in information processing mechanism of the prefrontal cortex.

Bcl-2 oncoprotein is being localized to mitochondria and interfering with programmed cell death (apoptosis) independent of promoting cell division in the lymphoid and nonlymphoid cells. The bcl-2 oncoprotein expression has been reported in follicular lymphomas as well as in diffuse non-Hodgkin's lymphoma, leukemia and a variable propotion of Hodgkin's lymphoma cases. Recent evidence suggests that some lymphomas protected from apoptosis is conferred through expression of Epstein-Barr virus(EBV) latent membrane protein which turn to cause upregulation of bcl-2. To define the role of the bcl-2 oncoprotein and EBV in lymphoid malignancy, we tried immunohistochemical studies with anti-bcl-2 antibody and In situ hybridization (ISH) with EBV-encoded small nuclear RNAs(EBER) in the paraffin embedded sections of 46 non-Hodgkin's lymphoma (NHL) cases and 20 Hodgkin's lymphoma (HL) cases. Bcl-2 oncoprotein expression was found in 37 of 46 cases (80%) of NHL with relatively strong cytoplasmic staining, and in 14 of 20 cases (70%) of HL with weak cytoplasmic staining in limited small numbers of RS, Hodgkin and lacunar cells. The widespread presence of bcl-2 oncogene in many different types of both NHL and HL supports that the extended cell survival through overexpression of bcl-2 gene protein may be a growth advantage of neoplastic lymphoid cells. In the ISH analysis for EBV, the presence of EBV was detected in 17 of 20 cases (85%) of HL, compared to 6 of 44 cases(13.6%) of NHL. It appears to be no direct correlation between overexpression of bcl-2 oncoprotein by neoplastic lymphoid cells and the presence of EBV in NHL but it seems to be a definite association between EBV and HL.
