Background Inhibition and eradication of Staphylococcus aureus biofilms with conventional antibiotic is difficult, the treatment further complicated by rise resistance among staphylococci. Consequently, there a need for novel antimicrobials that can treat biofilm-related infections decrease antibiotics burden. Natural compounds such as eugenol anti-microbial properties are attractive agents could reduce use antibiotics. In this study we evaluated effect on MRSA MSSA in vitro bacterial...
Pulsed corona induced plasma chemical process (PPCP) has been investigated for the simultaneous removal of NOx (nitrogen oxides) and SO2 (sulfur dioxide) from flue gas emission. It is one world's largest scales PPCP treating simultaneously. A unit equipped with an average 120 kW modulator installed tested at industrial incinerator flow rate 42 000 m3/h. To improve efficiency NOx, ammonia (NH3) propylene (C3H6) were used as additives. was observed that pulsed made significant conversion...
Highlights • Delta check limits were established for frequently requested hormones An absolute delta percent is recommended to verify common adrenocorticotropic hormone should be set separately inpatients and outpatients This foundational data helps in laboratories
Several factors contribute to differences in Streptococcus pneumoniae serotype distribution. We investigated the distribution and antimicrobial resistance of S. isolated between 2014 2016 Korea.We collected a total 1,855 isolates from 44 hospitals May 2016, analyzed serotypes by sequential multiplex PCR. each patient age, source clinical specimen, pattern.The most common were 11A (10.1%), followed 19A (8.8%), 3 (8.5%), 34 (8.1%), 23A (7.3%), 35B (6.2%). The major invasive (12.6%), (7.8%),...
Automated Mediace Treponema pallidum latex agglutination (TPLA) and rapid plasma reagin (RPR) assays are used by many laboratories for syphilis diagnosis. This study compared the results of traditional screening algorithm a reverse using automated RPR or TPLA as first-line in subjects undergoing health checkup.Samples from 24,681 persons were included this study. We routinely performed simultaneously. Results analyzed according to both algorithm. Samples with discordant on (e.g., positive...

Recently, a consensus report for microscopic schistocyte determination was prepared by International Council Standardization in Hematology (ICSH). ICSH focused on diagnosis of thrombocytopenic purpura (TTP)/hemolytic uremic syndrome (HUS). We aimed to reanalyze schistocytes according recommendations, study diseases other than TTP/HUS related the schistocytes, and compare percentage among various diseases.We retrieved all reported cases peripheral blood (PB) smear single institution during 6...
We propose a framework for design roadmapping that parallels existing product and technology processes. It leverages three needs we have observed in organizations as they use processes: (1) to focus on development of customer user experiences (UX), not just features; (2) increase engagement designers early the planning process; (3) provide means rapidly responding changes environment. Design is an attempt reconcile differences arise when customer/user are considered simultaneously with...
This study aimed to determine practical delta check limits (DCLs) for thyroid function tests (TFTs) detect sample misidentifications across various clinical settings. Between 2020 and 2022, 610,437 paired TFT results were collected from six university hospitals. The absolute DCL (absDCL) was determined using the 95th percentile each setting a random 60 % of total data. These absDCLs then tested within different settings remaining 40 data, alongside mix-up datasets result comparisons....
Tonsil-derived mesenchymal stem cells were extracted and used to fabricate parathyroid organoids. By modeling both the organoid vasculature, this system can simulate hormone secretion based on calcium concentration.
Procalcitonin (PCT) may prove to be a useful marker exclude or predict bloodstream infection (BSI). However, the ability of PCT levels differentiate BSI from non-BSI episodes has not been evaluated in nosocomial BSI.We retrospectively reviewed medical records patients ≥ 18 years age with suspected that developed more than 48 hours after admission.Of 785 included patients, 105 (13.4%) had and 680 (86.6%) episodes. The median serum level was elevated as compared those without (0.65 ng/mL vs....
The quality of laboratory test results is crucial for accurate clinical diagnosis and treatment. Pre-analytical errors account approximately 60%-70% all errors. Laboratory may be largely impacted by pre-analytical phase management. However, primary care clinics currently do not have management audit systems. We aimed to understand the current status in medicine Korean clinics.Questionnaires were designed focus on essential components process clinics. An online survey platform was used...
Abstract Background Although plasma free hemoglobin (fHb) test is important for assessing intravascular hemolysis, it still dependent on the gold standard Harboe method using manual and labor‐intensive spectrometric measurements at wavelength of 380‐415‐450 nm. We established an automated fHb assay a routine chemistry autoanalyzer that can be tuned to 380‐416‐450 Methods The linearity, precision, accuracy, correlation, sample carryover measurement TBA200FRneo were evaluated, respectively....
Therapeutic drug monitoring (TDM) of tacrolimus is essential because narrow therapeutic range and poor correlation dose to blood concentration. Affinity Column Mediated Immunometric Assay (ACMIA) does not require a pretreatment steps in measurement tacrolimus. In this study, we evaluated the performance assay using ACMIA (Dimension RxL Max, Dade Behring).The imprecision, linearity detection limits interferences by bilirubin chyle, with hematocrit for were according Clinical Laboratory...
Background/Aims Diagnostic stool multiplex polymerase chain reaction (PCR) testing has attracted considerable interest, because of its high sensitivity, short turnaround time, and ability to detect multiple organisms simultaneously. This study investigates the clinical usefulness a bacterial PCR in patients with acute diarrhea. Methods We retrospectively evaluated results, parameters, courses hospitalized diarrhea between August 2014 November 2016. Results A total 725 (male, 372; mean age,...
Objectives To assess the current state of anemia evaluation in elderly over 80 years age. Methods Patients who were more than old and visited Dongguk University Ilsan Hospital from April 2005 to February 2014 included. Statistical analysis assessed using logistic regression model. Results Total 548 patients, had according WHO criteria, identified. The median age was 85 (range, 82 99 years) hemoglobin level 11.0 g/dL 2.7 12.9 g/dL). Twenty-eight, 468, 52 patients classified as microcytic...

In Korea, the Korean Laboratory Accreditation Program (KLAP) has set minimum standards for verification of clinical test performance. This process is time-consuming and labor-intensive when performed manually. We developed a free, statistical software program KLAP, using R language (R Foundation Statistical Computing, Vienna, Austria).We used CLSI guidelines algorithm. built graphic user interfaces, including data input, with Embarcadero Delphi EX4 (Embarcadero Technologies, Inc., Texas,...
