It has been stated that active-transmission electrodes should improve signal quality in mobile EEG recordings. However, few studies have directly compared active- and passive-transmission electrodes during a mobile task. In this repeated measurement study, we investigated the performance of active and passive signal transmission electrodes with the same amplifier system in their respective typical configurations, during a mobile auditory task. The task was an auditory discrimination (1,000 vs. 800 Hz; counterbalanced) oddball task using approximately 560 trials (15% targets) for each condition. Eighteen participants performed the auditory oddball task both while standing and walking in an outdoor environment. While walking, there was a significant decrease in P3 amplitude, post-trial rejection trial numbers, and signal-to-noise ratio (SNR). No significant differences were found in signal quality between the two electrode configurations. SNR and P3 amplitude were test-retest reliable between recordings. We conclude that adequate use of a passive EEG electrode system achieves signal quality equivalent to that of an active system during a mobile task.

The outbreak of COVID-19 necessitated a move to online teaching and assessment. The objective structured clinical examination (OSCE) has been an integral part of dental examinations for several decades. The COVID-19 pandemic stopped face to face examinations around the world. An Online Virtual OSCE (VOSCE) was developed and piloted for dental undergraduate assessment.

This initial report outlines the steps required to run an OSCE online. Planning and preparation required in adaptation of an OSCE for the online environment is dreported. The necessity for familiarisation sessions is addressed, and VOSCE logistics described.

With careful planning, the VOSCE is a useful assessment method in difficult times. Feedback from staff and students was favourable.

Although significant organisation was required, the examination process worked well for both students and examiners. Despite limitations in relation to technical dental procedures, the VOSCE could be a viable alternative to face to face clinical examination.

A few studies using data from regional databases have recently pointed to a decreased number of patients with stroke. The aim of the present study was to describe country-level data (the number of patients with stroke, the proportion of patients with acute stroke and transient ischemic attack (TIA), the proportion of patients treated with intravenous thrombolysis [IVT] or mechanical thrombectomy [MT], the door-to-needle times [DNT], and the onset-to-needle time [ONT]) during the COVID-19 pandemic in Slovakia.

The study examined data from the stroke register at the National Health Information Centre. Data from three time periods (March to April 2020; March to April 2019; January to February 2020) were compared using an independent samples t-test and the Wilcoxon-Mann-Whitney two-sample rank-sum test.

The number of stroke patients admitted to hospitals in Slovakia during the COVID-19 period showed a decrease (1673 vs. 2328 in period 2 and 2155 in period 3). The proportions of patients with TIA remained the same in periods 1 and 2 (9.7% vs. TGF-beta tumor 11.7%) and in periods 1 and 3 (9.7 vs. 11.8%). The percentage of patients treated with IVT during the pandemic (22.4%) did not differ from period 2 (20.0%) or period 3 (21.4%). No difference was found in the rate of MT between the COVID-19 period (10.2%) and the same period in 2019 (10.7%) and in January to February 2020 (13.1%). The median DNT remained unchanged in periods 1 (30min), 2 (35min) and 3 (30min), and no differences were found in median ONT in periods 1 (130min), 2 (130min) and 3 (140min).

We found a decreased number of stroke patients during the COVID-19 outbreak in Slovakia, but no evidence of achange in the quality of acute stroke care.

A crucial improvement of the Lx conjugation reaction from initially less then 15 % to ca. 75-90 % conjugation efficiency is described, resulting from a systematic screening of all relevant reaction parameters. NaI, a strikingly simple inorganic salt additive, greatly improves the conjugation efficiency as well as the conjugation selectivity simply by exchanging the leaving chloride ligand on Cl-Lx-drug complexes (which are direct precursors for Lx-ADCs) for iodide, thus generating I-Lx-drug complexes as more reactive species. Using this iodide effect, we developed a general and highly practical conjugation procedure that is scalable our lead Lx-ADC was produced on a 5 g scale with an outstanding conjugation efficiency of 89 %.Testis-specific protein Y-encoded 1 (TSPY1), a Y chromosome-linked oncogene, is frequently activated in prostate cancers (PCa) and its expression is correlated with the poor prognosis of PCa. However, the cause of the ectopic transcription of TSPY1 in PCa remains unclear. Here, we observed that the methylation status in the CpG islands (CGI) of the TSPY1 promoter was negatively correlated with its expression level in different human samples. The acetyl-histone H4 and trimethylated histone H3-lysine 4, two post-translational modifications of histones occupying the TSPY1 promoter, facilitated the TSPY1 expression in PCa cells. In addition, we found that androgen accelerated the TSPY1 transcription on the condition of hypomethylated of TSPY1-CGI and promoted PCa cell proliferation. Moreover, the binding of androgen receptor (AR) to the TSPY1 promoter, enhancing TSPY1 transcription, was detected in PCa cells. Taken together, our findings identified the regulation of DNA methylation, acting as a primary mechanism, on TSPY1 expression in PCa, and revealed that TSPY1 is an androgen-AR axis-regulated oncogene, suggesting a novel and potential target for PCa therapy.
