However, their clinical outcomes have been heavily restricted by severe systemic toxicities. To ensure biosafety and efficiency, herein, we constructed a disulfide bond inserted Pt(IV) self-assembled nanoplatform that is selectively activated by rich glutathione (GSH) in tumor site. Disulfide bond was introduced into the conjugates of oxaliplatin (IV) and oleic acid (OA) which conferred cascade reduction-responsiveness to nanoassemblies. Disulfide bond cleavage and reduction of Pt(IV) center occur sequentially as a cascade process. In comparison to oxaliplatin solution, Pt(IV) nanoparticles (NPs) achieved prolonged blood circulation and higher maximum tolerated doses. Furthermore, Oxa(IV)-SS-OA prodrug NPs exhibited potent anti-tumor efficiency against 4T1 cells and low toxicities in other normal tissues, which offers a promising nano-platform for potential clinical application.Boron nitride (BN) nanosheets have emerged as promising nanomaterials in a wide range of biomedical applications. Despite extensive studies on these bio-nano interfacial systems, the underlying molecular mechanisms remain elusive. In this study, we used hemolysis assays and morphology observations to demonstrate for the first time that BN nanosheets can cause damages to the red-blood-cell membranes, leading to significant hemolysis. Further molecular dynamics simulations revealed that BN nanosheets can penetrate into the cell membrane and also extract considerable amount of phospholipid molecules directly from the lipid bilayer. The potential of mean force calculations then showed that their penetration effect was thermodynamically favorable due to the strong attractive van der Waals interactions between BN nanosheets and phospholipids. Overall, these findings provided valuable insights into the interaction of BN nanosheets with cell membranes at the atomic level, which can help future de novo design of BN-based nanodevices with better biocompatibility.Starting from established CYP3A4 Template (DMPK. 2019, and 2020), CYP3A5 and CYP3A7 Templates have been constructed to be reliable tools for verification of their distinct catalytic properties. A distinct occupancy was observed on CYP3A4-selective ligands, but not on the non-selective ligands, in simulation experiments. These ligands often invade into Bay-1 region during the migration from Entrance to Site of oxidation in simulation experiments. These results offered an idea of the distinct localization of Bay-1 residue on CYP3A5 Template, in which the Bay-1 residue stayed closely to Template border. The idea also accounted for the higher oxidation rates of CYP3A5, than of CYP3A4, of noscapine and schisantherin E through their enhanced sitting-stabilization. Typical CYP3A7 substrates such as zonisamide and retinoic acids took their placements without occupying a left side region of Template for their metabolisms. In turn, the occupancies of the left-side region were inevitably observed among poor ligands of CYP3A7. Altered extent of IJK-Interaction or localization of a specific residue at the left-side would thus explain distinct catalytic properties of CYP3A7 on Template. These data suggest the alteration of each one of Template region, from CYP3A4 Template, led to the distinct catalytic properties of CYP3A5 and CYP3A7 forms.Previous research by Hazan-Liran & Miller (2017) developed a new Stroop-like task to examine how ink colours as task-irrelevant information affects paired-associate learning (see also Miller, Hazan-Liran, & Cohen, 2018). The task was to learn word-number pairs (e.g. blue-5) whilst only numbers were coloured in either congruent ink colours (e.g. number 5 printed in blue ink), incongruent ink colours (e.g. 5 printed in brown ink) or neutral ink colours (e.g. 5 printed in black ink). The present paper refers to this task as the Associative Memory Stroop Task (AMST). Hazan-Liran & Miller (2017) found that incongruent ink colours interfere and congruent ink colour facilitate the speed of learning word-number pairs. The present experiments employed the AMST to examine the effects of irrelevant ink colours (with colour names) on memory accuracy in cued recall and associative recognition. Memory impairment was found with incongruent ink colours on both memory tests whilst improved memory accuracy with congruent ink colours was not reliable. We discuss possible explanations for these findings.
Atrial appendage aneurysm in dogs is a rare condition and has not been well described. The aim of this study is to describe clinical and diagnostic imaging findings, especially computed tomography (CT), of atrial appendage aneurysms in dogs.

Seven client-owned dogs with a presumptive diagnosis of left or right atrial appendage aneurysm.

Retrospective study. Medical records were searched to identify dogs with a presumptive diagnosis of left (LAAA) or right atrial appendage aneurysm (RAAA). Signalment, history, examination findings, diagnostic test results, and imaging procedures were reviewed. Archived diagnostic images were retrieved and evaluated by two board-certified radiologists and a board-certified cardiologist. Data analysis was descriptive.

Six cases were diagnosed with RAAA and one with LAAA with a median age of 8 years. Five affected dogs were small to medium-breed male dogs. All dogs underwent a thoracic CT examination for various reasons and all cases of RAAA were incidental findings. CT was useful to identify and assess the atrial appendage aneurysm, as well as neighboring structures, although possible pericardial defects could not be visualized. Five dogs had a concurrent echocardiographic examination, which successfully identified the LAAA and two RAAA.

This case series described the clinical and CT findings in seven dogs with atrial appendage aneurysm, as well as echocardiographic findings in five of these cases. Right atrial appendage aneurysms appear to be mainly incidental findings. CT seems to be more sensitive than echocardiography in the detection of atrial appendage aneurysm.

Nonalcoholic fatty liver disease is inconsistently associated with ischemic stroke, with one study suggesting an association in women and not men. The relative importance of liver fibrosis, as opposed to fatty liver, for cardiovascular risk is increasingly appreciated. We hypothesized that advanced liver fibrosis is associated with incident ischemic stroke risk, and especially in women.

We performed a case-cohort study in the REasons for Geographic and Racial Differences in Stroke cohort. Black and white individuals aged 45 and older were recruited between 2003 and 2007 and followed for ischemic stroke. The Fibrosis-4 (FIB-4) score and Nonalcoholic Fatty Liver Disease Fibrosis Score (NFS) were calculated using baseline data for stroke cases and a cohort random sample; advanced liver fibrosis was classified using validated cutoffs. Cox proportional hazards models were used to estimate hazard ratios (HR) of stroke after adjusting for potential confounders. Sex differences were assessed.

There were 572 incident ischemic strokes (285 in women) over 5.4 (SD, 2.2) years. Advanced liver fibrosis was not significantly associated with ischemic stroke overall using the FIB-4 (HR 1.44; 95% CI 0.49-4.28) or NFS (HR 1.76; 95% CI 0.67-4.61). However, liver fibrosis was associated with stroke in women (HR 3.51; 95% CI 1.00-12.34) but not men (HR 0.70, 95% CI 0.16-3.16) (P=0.098 for interaction) when using FIB-4. A similar but non-significant sex difference was seen for NFS.

Advanced liver fibrosis may be associated with a higher risk of ischemic stroke in women but not men.

to report an unusual pattern of brain petechial hemorrhages in2 patients after veno-arterial extracorporeal membrane oxygenation support (VA-ECMO) CASE 1 a 28-year-old man (Marfan disease) presented in the early post-operative period a multi-organ failure associated with a disseminated intravascular coagulation (DIC). He was placed on continuous veno-venous hemofiltration and VA-ECMO. He was weaned from ECMO 4 days later. He then developed bacterial pneumoniae leading to respiratory failure and requiring mechanical ventilation. MRI 30 days later showed widespread petechial hemorrhages in the subcortical and deep white matter (WM) (optic radiations, corpus callosum, predominantly in the splenium, internal and external capsules), caudate nuclei, basal ganglia, frontal and parietal cortex and in infratentorial structures. These hemorrhages were bilateral and almost symmetric and marked at the border zones of the carotid arteries territories. CASE 2 a 60-year-old man presented an out-of-hospital refractory hypotifactorial cause.While use of telemedicine to guide emergent treatment of ischemic stroke is well established, the COVID-19 pandemic motivated the rapid expansion of care via telemedicine to provide consistent care while reducing patient and provider exposure and preserving personal protective equipment. Temporary changes in re-imbursement, inclusion of home office and patient home environments, and increased access to telehealth technologies by patients, health care staff and health care facilities were key to provide an environment for creative and consistent high-quality stroke care. The continuum of care via telestroke has broadened to include prehospital, inter-facility and intra-facility hospital-based services, stroke telerehabilitation, and ambulatory telestroke. However, disparities in technology access remain a challenge. Preservation of reimbursement and the reduction of regulatory burden that was initiated during the public health emergency will be necessary to maintain expanded patient access to the full complement of telestroke services. Here we outline many of these initiatives and discuss potential opportunities for optimal use of technology in stroke care through and beyond the pandemic.Bisphenol A (BPA) is a ubiquitous industrial chemical found in everyday plastic products and materials. Due to scientific findings on the reproductive, developmental, and cellular defects caused by BPA and heightened public awareness, manufacturers have begun to use new chemicals in place of BPA in "BPA-free" products. These alternatives are chemical analogs of BPA and include dozens of new compounds that have undergone relatively little testing and oversight, including bisphenol S (BPS), bisphenol AF (BPAF), and the recently developed tetramethyl bisphenol F (TMBPF; the monomer of valPure V70). Here, we used adult female rat adipose-derived stem cells (rASCs) and human mesenchymal stem cells (hMSCs) to compare the toxicities and potencies of these BPA alternatives in vitro. Rat and human stem cells were exposed to BPA (1-10 μM), 17β-estradiol (E2; 10 μM), BPS (1-100 μM), BPAF (3×10-4-30 μM), TMBPF (0.01-50 μM), or control media alone (with 0.01% ethanol) for varying time intervals from 10 min to 24 h. We found significantly decreased cell viability and massive apoptosis in rat and human stem cells treated with each BPA analog, as early as 10 min of exposure, and at low, physiologically relevant doses.
