TL;DR: In this paper, the authors analyzed plasma levels of pro-and anti-inflammatory cytokines in acute myeloid leukemia (AML) patients and age-matched healthy donors and found that plasma TNF-α, IL-6 and IL-10 levels were higher in AML patients from both groups of age.

TL;DR: The results show that COVID-19-associated chemosensory impairment is not limited to smell, but also affects taste and chemesthesis, and suggest that SARS-CoV-2 infection may disrupt sensory-neural mechanisms.
Abstract: Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, generally lacked quantitative measurements, were mostly restricted to data from single countries. Here, we report the development, implementation and initial results of a multi-lingual, international questionnaire to assess self-reported quantity and quality of perception in three distinct chemosensory modalities (smell, taste, and chemesthesis) before and during COVID-19. In the first 11 days after questionnaire launch, 4039 participants (2913 women, 1118 men, 8 other, ages 19-79) reported a COVID-19 diagnosis either via laboratory tests or clinical assessment. Importantly, smell, taste and chemesthetic function were each significantly reduced compared to their status before the disease. Difference scores (maximum possible change+/-100) revealed a mean reduction of smell (-79.7+/- 28.7, mean+/- SD), taste (-69.0+/- 32.6), and chemesthetic (-37.3+/- 36.2) function during COVID-19. Qualitative changes in olfactory ability (parosmia and phantosmia) were relatively rare and correlated with smell loss. Importantly, perceived nasal obstruction did not account for smell loss. Furthermore, chemosensory impairments were similar between participants in the laboratory test and clinical assessment groups. These results show that COVID-19-associated chemosensory impairment is not limited to smell, but also affects taste and chemesthesis. The multimodal impact of COVID-19 and lack of perceived nasal obstruction suggest that SARS-CoV-2 infection may disrupt sensory-neural mechanisms.

TL;DR: The use of UV treatment prior to implantation protocols is proposed as an easy, economic and effective way of reducing bacterial adhesion on the Ti6Al4V surface without compromising its excellent biocompatibility.

TL;DR: In this paper, a modified version of the classical Van der Pol oscillator is proposed, introducing fractional-order time derivatives into the state-space model, which is analyzed in the time and frequency domains, using phase portraits, spectral analysis and bifurcation diagrams.
Abstract: In this paper a modified version of the classical Van der Pol oscillator is proposed, introducing fractional-order time derivatives into the state-space model. The resulting fractional-order Van der Pol oscillator is analyzed in the time and frequency domains, using phase portraits, spectral analysis and bifurcation diagrams. The fractional-order dynamics is illustrated through numerical simulations of the proposed schemes using approximations to fractional-order operators. Finally, the analysis is extended to the forced Van der Pol oscillator.
