Abstract:
DNA nanoball sequencing (DNBSEQ) is one of the most rapidly developing sequencing technologies and is widely applied in genomic and transcriptomic investigations. Recently, a new PE300 sequencing option primarily recommended for amplicon analysis was released for DNBSEQ-G99 and G400 devices. Given their unprecedentedly high data yield per flow cell, the new PE300 kits could be a great choice for various sequencing tasks, but we found that combining different types of DNA libraries in a single run could lead to undesired artifacts in the data.

Based on this our Objective of study is to determine the effectiveness of immunohistochemical observation, a quick and easy method for determining MSI and/or other types of EC which based on modern classification. As molecular study takes more cost we want to compare the both methods an

e17570 Background: Homologous recombination deficiency (HRD) is a pivotal biomarker for predicting response to PARP inhibitors in multiple cancers. This study evaluates the analytical performance of a 53-gene somatic NGS panel combined with low-pass whole genome sequencing (shallow WGS, sWGS) for HRD assessment. Methods: In the present study, 36 FFPE tissues from ovarian cancer patients were analyzed for 52 genes implicated in DNA repair pathways, along with sWGS for the evaluation of tumor genomic instability (GI). Libraries were generated with the KAPA HyperPlus Kit (Roche) and sequenced in

Abstract:
Introduction: Recombinant human erythropoietin (rHuEPO) administration studies involving transcriptomic approaches have demonstrated a gene expression signature that could aid blood doping detection. However, current anti-doping testing does not involve collecting whole blood into tubes with RNA preservative. This study investigated if whole blood in long-term storage and whole blood left over from standard hematological testing in short-term storage could be used for transcriptomic analysis despite lacking RNA preservation.Methods: Whole blood samples were collected from twelve and fourteen h

Abstract:
Blackcurrants (Ribes nigrum) are among the most important commercial berry crops in Latvia and, together with redcurrants and gooseberries, have a long history of local cultivation and breeding (Zuļģe et al. 2018). So far at least 20 viruses were reported to infect Ribes plants (Špak et al. 2021). Blackcurrant-associated rhabdovirus (BCaRV) was previously identified in USA by high throughput sequencing (HTS) of blackcurrant germplasm accession introduced from Russia (isolate Veloy) and now serves as an exemplar isolate for BCaRV (Wu et al. 2018). Presence of BCaRV was also confirmed by RT-PCR

Abstract Study question Is the vaginal or faecal microbiome different between primary RPL (pRPL) and secondary RPL (sRPL) patients, and is it related to reproductive outcome after referral? Summary answer Before pregnancy, the vaginal microbiome differed between pRPL and sRPL, and the faecal microbiome was altered in those who did not achieve pregnancy after follow-up. What is known already RPL is a heterogeneous condition leaving 50% of the couples without any known risk factors after the initial diagnostic workup. The microbiome of the reproductive tract seems to be an essential factor in wo

Abstract Study question Could controlled ovarian stimulation protocol (progestin-primed ovarian stimulation [PPOS] vs GnRH-antagonist [GnRH-ant]) affect the gene expression of human immune cells (ICs) in preovulatory follicles? Summary answer Proinflammatory cytokine-related gene expression was significantly higher and proinflammatory pathways were also more prominently involved in ICs in PPOS than the GnRH-ant. What is known already PPOS has garnered attention, with several studies suggesting reproductive outcomes comparable to GnRH-ant. However, in our previous study, pregnancy outcomes with
