Mikrobiyol Bul 2020 Oct;54(4):619-628

Istanbul University Cerrahpasa Medical Faculty, Department of Medical Microbiology, İstanbul, Turkey.

CMV is a virus that is asymptomatic in healthy individuals but can cause serious mortality and morbidity in transplant patients and patients with acquired immunodeficiency syndrome (AIDS). Ganciclovir (GCV) is a nucleoside analog that significantly reduces morbidity and mortality in CMV-related infections and is used as the first choice in treatment. It is the first drug shown to be effective in the treatment of CMV disease in humans, and is also homologous to acyclovir. Read More

Department of Orthopaedics, Kaohsiung Veterans General Hospital, Taiwan; Nursing College, Fooyin University, Kaohsiung, Taiwan. Electronic address:

Background: We intended to clarify the effect of gender and A118G polymorphism of Opioid Receptor μ1 (OPRM1) on the required morphine for patients to maintain Visual Analogue Scale ≦ 3 for post-operative pain control after total knee replacement (TKR).

Methods: With approval from Institutional Review Board (IRB) and obtainment of informed consents, 111 patients undergoing primary TKR were enrolled without violating the exclusion criteria, including previous history of allergy to morphine, alcohol or substance abuse, use of psychotropic medications, morbid obesity of body mass index (BMI) > 40 kg/m, chronic pain with evidence of central sensitization, and uncooperative use of patient controlled analgesia (PCA) device. The amount of PCA-delivered morphine for pain control and the 'demand' (the count of button pushing for requiring pain medication from PCA) were recorded at 3, 6, 12, 24, 36, 48 and 72 h after the operation.

Shiraz Institute for Cancer Research, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.

To find out if the T cell repertoire is efficiently and specifically provoked in patients with breast cancer, we have investigated the clonotypes of main T cell subsets (based on Vβ-Chain) in tumor draining lymph nodes. CD4+ helper, CD8+ cytotoxic and (CD4+CD127dimCD25+) regulatory T cells, were negatively selected, and isolated, from lymph node mononuclear cells of 14 untreated patients with breast cancer. Four non-malignant patients, who underwent surgical operation, were also recruited as the control group. Read More

A new cost and time effective method for multilocus microsatellite typing (MLMT) studies: Application of Leishmania tropica isolates and clinical samples from Turkey.

J Microbiol Methods 2017 10 14;141:97-100. Epub 2017 Aug 14.

Ege University, Faculty of Medicine, Parasitology Department, Izmir, Turkey.

Molecular techniques are widely used in the field of parasitology to identify the genetic profile of the microbiological agents. Microsatellite typing studies are comprised of the amplification of polymorphic markers to analyze the fragment sizes using bioinformatics tools. Current methods need fluorescently labeled primers and size markers to obtain fragment peaks in ABI PRISM® systems and due to low discrimination power of gel-electrophoresis, it is not possible to differentiate primer-dimers from small fragments In the present study, we designed a new method for fragment analysis studies, which reduce the time by eliminating the classical PCR, the gel-electrophoresis and the preparation steps of fragment analysis.

"Squirrel" Primer-Based PCR Assay for Direct and Targeted Sanger Sequencing of Short Genomic Segments.

J Biomol Tech 2017 Sep 6;28(3):97-110. Epub 2017 Jun 6.

Division of Cancer and Stem Cell, Faculty of Medicine and Health Sciences, University of Nottingham, Nottingham, United Kingdom.

Currently, short DNA segments of sub-100 bp can be sequenced either directly by next-generation sequencing and pyrosequencing, which are expensive, or indirectly, Sanger sequencing combined with the cumbersome and failure-prone plasmid cloning. To circumvent these issues, we have generated a novel sequencing-purposed PCR assay using long-tailed primers (squirrel primers) to Sanger sequence directly sub-100 bp genomic amplicons. Squirrel primers, 40-65 nt in length, were used to amplify 51-93 bp long genomic sequences of exons 2 and 3, exon 15, exon 20, and exon 3 from colorectal cancer (CRC) cell lines and preamplified clinical CRC samples with known mutation status by PCR.
