Considering the high incidence of plasma mSEPT9 in intestinal or mixed type GCs similar to CRCs, GC should be examined through the plasma mSEPT9 screening test. In addition, plasma mSEPT9 is proposed as a follow-up marker in CRC patients, but further validation is required.

<i>tuf</i> Gene Sequence Analysis Has Greater Discriminatory Power than 16S rRNA Sequence Analysis in Identification of Clinical Isolates of Coagulase-Negative Staphylococci
Sang Mee Hwang, Myoung Shin Kim, Kyoung Un Park, Junghan Song, Eui-Chong Kim
SJR Q1FWCI 1.1Journal of Clinical MicrobiologyOA

We compared and analyzed 16S rRNA and tuf gene sequences for 97 clinical isolates of coagulase-negative staphylococci (CNS) by use of the GenBank, MicroSeq, EzTaxon, and BIBI databases. Discordant results for definitive identification were observed and differed according to the different databases and target genes. Although higher percentages of sequence identity were obtained with GenBank and MicroSeq for 16S rRNA analysis, the BIBI and EzTaxon databases produced less ambiguous results. Greater

RHD genotyping is not required in half of D-negative cases. We suggest here an effective RHD genotyping strategy for accurate detection of RhD variants in apparently RhD-negative blood donors in East Asia.

Expression of Lewis antigens and their precursors in gastric mucosa: relationship with <i>Helicobacter pylori</i> infection and gastric carcinogenesis
Hye Seung Lee, Gheeyoung Choe, W H Kim, HH Kim, Junha Song, Kyoung Un Park
SJR Q1FWCI 3.0The Journal of Pathology

Lewis (Le)-associated antigens are carbohydrates that are related biochemically to the ABO blood groups, and may have a role in Helicobacter pylori adherence. To evaluate their relationship to clinicopathological outcomes, gastric Le expression, including type 1 precursor, type 1 H, Le(a), Le(b), Le(x), Le(y) and sialylated Le(a) (CA19-9), was evaluated immunohistochemically in 233 gastric biopsy specimens obtained at routine gastroscopy. Expression was also investigated in gastric tissues showi

Gene Expression Analysis of Ex Vivo Expanded and Freshly Isolated NK Cells From Cancer Patients

SJR Q1FWCI 0.6Journal of ImmunotherapyOA

The infusion of natural killer (NK) cells is a promising therapy for patients with advanced malignancies. Clinical expanded NK-cell products were compared with freshly isolated NK cells. Autologous peripheral blood mononuclear cells were collected by apheresis from 8 patients. NK cells were isolated by anti-CD3-negative selection followed by anti-CD56-positive selection. They were then expanded by co-culture with interleukin-2 and an irradiated Epstein-Barr virus (EBV)-transformed lymphoblastoid

Factors influencing oral microbiome analysis: from saliva sampling methods to next-generation sequencing platforms

SJR Q1FWCI 6.1Scientific ReportsOA

The exploration of oral microbiome has been increasing due to its relatedness with various systemic diseases, but standardization of saliva sampling for microbiome analysis has not been established, contributing to the lack of data comparability. Here, we evaluated the factors that influence the microbiome data. Saliva samples were collected by the two collection methods (passive drooling and mouthwash) using three saliva-preservation methods (OMNIgene, DNA/RNA shield, and simple collection). A

BILATERAL SAME-DAY INTRAVITREAL INJECTIONS USING A SINGLE VIAL AND MOLECULAR BACTERIAL SCREENING FOR SAFETY SURVEILLANCE

SJR Q1FWCI 3.2Retina

Bilateral same-day intravitreal injections drawn from a single vial using separate syringes or needles are well tolerated by patients, and its safety profile may be equivalent to unilateral injections. The bacterial molecular surveillance system using eubacterial PCR demonstrated the safety of bilateral same-day intravitreal injections and may be used for safety surveillance and for timely intervention of possible drug-related endophthalmitis.

SJR Q2FWCI 0.7Journal of Korean Medical ScienceOA

We report a case of Aspergillus terreus discitis which developed in a patient with acute lymphoblastic leukemia following induction chemotherapy. A. terreus was isolated from sputum, one month earlier, but the physician did not consider it significant at the time. Magnetic resonance imaging study showed the involvement of L3-4, L4-5 and L5-S1 intervertebral discs. Etiology was established by means of histology and culturing a surgical specimen of disc materials. Our patient survived after a surg
