Aim of the study Effect of internalized phthalyl starch nanoparticles (PSNs) on the antimicrobial ability of Lactococcus lactis (LL) KCTC 2013. Methods and results Phthalyl starch nanoparticles (PSNs) were prepared by self-assembly of phthalyl starch and the amount of the hydrophobic phthalic moieties were characterized by nuclear magnetic resonance (NMR), PSN1 (DS 14.3 mol.-%), PSN2 (DS 17.8 mol.-%) and PSN3 (DS 30.4 mol.-%), the sizes of PSN1, PSN2, and PSN3 measured by dynamic light scattering (DLS) were 364.7, 248,4 and 213.4 nm respectively, the surface charges of PSNs measured by electrophoretic light scattering (ELS) were negative charges and according to scanning electron microscope (SEM) PSNs looked as spherical shapes. It was found that when PSNs were treated to LL, the PSNs were internalized into LL through nanoparticle size-, energy-, and glucose transporter-dependent mechanisms. The internalization was confirmed by confocal laser scanning microscopy (CLSM) and fluorescence-activated cell sorting ew method for the biological production of such antimicrobial peptides.Two months have passed since the World Health Organization (WHO) declared the pandemic of the Coronavirus Disease 19 (COVID-19), caused by the SARS-CoV-2 virus, on 11 March 2020. Medical and healthcare workers have continued to be on the frontline to defeat this disease, however, continual changes are being made to their working habits which are proving to be difficult. Although the skin is not the main target of the SARS-CoV-2 infection, it is strongly involved both directly and indirectly, in many aspects of dermatological disease management, and particularly in pediatric dermatology. In this manuscript, our goal was to provide a "up-to-date" account on this topic, through analysis of current literature and sharing our experiences during this pandemic.Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy characterized by accumulation of hyperphosphorylated tau (p-tau) in perivascular aggregates in neurons and glia at the depths of neocortical sulci and progresses to diffuse neocortical, allocortical and brainstem structures. The strongest risk factor is exposure to repetitive head impacts acquired most commonly through contact sports and military service. Given that CTE can only be definitively diagnosed after death, a better understanding of the cellular and molecular changes in CTE brains may lead to identification of mechanisms that could be used for novel biomarkers, monitoring progression or therapeutic development. Disruption of alternative pre-mRNA splicing of tau mRNA plays a pathogenic role in tauopathy, with multiple characteristic patterns of isoform accumulation varying among tauopathies. see more Limited data are available on CTE, particularly at early stages. Using biochemical and histological approaches, we performed a detailed charrms that correlates with CTE stage and extent of neuronal pathology.Simple and stable synthesis of transition metal sulfides and clarification of their growth mechanisms are of great importance for developing catalysts, metal-air batteries and other technologies. In this work, we developed a one-step facile hydrothermal approach to successfully synthesize NiS2 microspheres. By changing the experimental parameters, the reason that affects the formation of nanostructured spheres is investigated and discussed in detail, and the formation mechanism of microspheres is proposed innovatively. Furthermore, electrochemical testing results show that the 7 h-NiS2 catalyst exhibits a remarkable oxygen evolution reaction (OER) activity with an overpotential of 311 mV at 10 mA cm-2 in 1.0 M KOH, superior to precious metal RuO2 . The NiS2 catalyst also exhibits a robust durability. This work will contributes to the rational design and the understanding of growth mechanism of transition metal chalcogenide electrocatalysts for diverse energy conversion technologies.Aim To evaluate the relationship between physiological and psychological stress on pregnancy outcome in women undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment. Methods Women undergoing the first IVF cycle were enrolled to complete the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS). Their blood samples were collected on the 3rd day of the menstrual cycle to measure 5-hydroxytryptamine, renin, norepinephrine, angiotensin II and cortisol. Salivary amylase was obtained on the embryo transfer day. Results Compared with normal women who came to the hospital for regular physical examination, the incidence of anxiety and depression was higher in women seeking for IVF treatment. After psychological intervention, the condition got improved and the incidence of anxiety and depression was 6.25% and 7.81% separately in these women. There were no significant differences between the anxiety scores in women with and without pregnancy. The depression scores did show some statistically differences, with higher scores in the nonpregnancy group. The level of 5-hydroxytryptamine, renin, norepinephrine and cortisol were not significantly different between the two groups, while angiotensin II and salivary amylase seemed to be negatively correlated with pregnancy outcome. Simultaneously, a positive correlation was found between angiotensin II and anxiety and depression scores. Conclusion Depression during IVF has a negative impact on pregnancy outcome. The measurement of angiotensin II and salivary amylase might be reference index for the psychological status of patients during IVF-ET.Reliable methodology applicable to highly efficient, enantioselective cis -dihydroxylation of tri-substituted alkenes, which has potential utility in organic synthesis, is scarce and unprecedented for non-osmium metal-based catalysis. In this work, an iron(II) complex, cis -α-[Fe II (2-Me 2 -BQPN)(OTf) 2 ], bearing tetradentate N 4 ligand 2-Me 2 -BQPN (( R , R )- N , N '-dimethyl- N , N '-bis(2-methylquinolin-8-yl)-1,2-diphenylethane-1,2-diamine) was prepared and characterized; with this complex as catalyst, a broad range of tri-substituted electron-deficient alkenes were efficiently oxidized to chiral cis -diols in isolated yields of up to 98% and enantioselectivities of up to 99.9% ee using hydrogen peroxide (H 2 O 2 ) as oxidant under mild conditions. Experimental studies (including 18 O-labeling and ESI-MS, NMR, EPR, and UV/Vis analyses) and DFT calculations were performed to gain mechanistic insight, suggesting possible involvement of a chiral cis -Fe V (O) 2 reaction intermediate as an active oxidant. The present work highlights the generality of the protocol " cis -[Fe II (chiral N 4 ligand)] 2+ + H 2 O 2 " as viable green alternative/complement to OsO 4 -reagent for asymmetric alkene dihydroxylation reactions that can be used in organic synthesis.
