A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets
Authors: Teboul Odelia , Metzger Brian D. 
Published: October 2023

Abstract
Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions. We propose that a key property responsible for both this surprisingly low rate and a variety of other observations is the typically large misalignment ψ between the orbital plane of the star and the spin axis of the supermassive black hole (SMBH). Such misaligned disk/jet systems undergo Lense–Thirring precession together about the SMBH spin axis. We find that TDE disks precess sufficiently rapidly that winds from the accretion disk will encase the system on large scales in a quasi-spherical outflow. We derive the critical jet efficiency η > η
crit for both aligned and misaligned precessing jets to successfully escape from the disk wind ejecta. As η
crit is higher for precessing jets, less powerful jets only escape after alignment with the SMBH spin. Alignment can occur through magneto-spin or hydrodynamic mechanisms, which we estimate occur on typical timescales of weeks and years, respectively. The dominant mechanism depends on η and the orbital penetration factor β. Hence, depending only on the intrinsic parameters of the event {ψ, η, β}, we propose that each TDE jet can either escape prior to alignment, thus exhibiting an erratic X-ray light curve and two-component radio afterglow (e.g., Swift J1644+57), or escape after alignment. Relatively rapid magneto-spin alignments produce relativistic jets exhibiting X-ray power-law decay and bright afterglows (e.g., AT2022cmc), while long hydrodynamic alignments give rise to late jet escape and delayed radio flares (e.g., AT2018hyz).

Published: October 2023

Introduction: The cardioplegic solution of Kirklin (Kn) is frequently used in adult cardiosurgical patients. It requires reinfusion at short intervals, which causes further difficulty during surgery and the quality of myocardial protection is often called into question.
Aim: To demonstrate whether the modified cardioplegia of del Nido (MDN) with a longer period of cardiac arrest provides sufficiently effective and reliable myocardial protection when compared to the classic cardioplegia of Kirklin we use in our institution.
Materials and methods: This ambispective clinical-epidemiological study was conducted in the Department of Heart Surgery at St Anna University Hospital in Sofia between January 2017 and September 2021. Using a random number generator, а hundred and twenty patients were selected and divided into two cohorts of 60 patients each. After further data processing, an additional five patients dropped out of the Kirklin group due to a ‘beating heart’ operative technique. As a result, the groups were divided as follows: 1) intermittent cardioplegia Kirklin (Kn, n=55) used in patients between January 2017 and June 2019, and 2) modified del Nido cardioplegia (MDN, n=60) used from June 2019 to September 2021.
Results: In this study, we present our experience with MDN cardioplegia in patients undergoing isolated CABG and compare it with a group of patients who received Kn cardioplegia. The difference in cross-clamp and CPB times is due to the individual qualities and experience of surgeons. When using MDN, the longer intraoperative times not only showed no deterioration in postoperative results, did not increase the need of using an additional dose of cardioplegia, but also did not materialize in a statistically significant difference. The MDN cardioplegia showed significantly less usage of inotropic support (p&lt;0.001) and IABP (p=0.029). Creatinine phosphokinase MB fraction when patients are admitted to intensive care was significantly less in the Kirklin group (p=0.045).
Conclusions: Results suggest that the routine use of modified cardioplegic protection of del Nido in adult patients may be safe, leads to comparable clinical outcomes and could accelerate the surgical process. The reduced incidence in intra- and postoperative complications like DC shocks, arrhythmia, myocardial infarction, multiorgan failure and in-hospital mortality should be further studied, as it may imply superiority of myocardial protection with the modified solution.
Prehemolytic impact of phenothiazine drugs on the attachment of spectrin network in red blood cells

Published: October 2023

Introduction: Chlorpromazine, thioridazine, and trifluoperazine are phenothiazine drugs that cause colloid-osmotic hemolysis of human erythrocytes by unknown mechanism. To clarify this mechanism, the impact of these drugs on the βsp (1.4 MHz) and γ1sp (9 MHz) dielectric relaxations was investigated. Each relaxation was shown to reduce its strength on the severing specific bridge that connects the spectrin network with the lipid membrane. For βsp relaxation, this is the spectrin-actin-glycophorin C bridge while for γ1sp relaxation this is the spectrin-ankyrin-band 3 bridge.
Aim: To elucidate the mechanisms of the effects of phenothiazine drugs in prehemolytic concentrations on the red blood cell plasma membrane using scanning temperature-dependent (thermal) differential dielectric spectroscopy.
Materials and methods: Erythrocytes were isolated from freshly drawn blood and 100 μl of them were suspended in 1 ml isotonic solution of 10 mM NaCl and mannitol (working medium) containing the indicated concentration of the drug for 10 min at 23°C. The treated erythrocytes were isolated, suspended in working medium, hematocrit 0.55, and heated (heating rate 1.5°C/min) above the denaturation temperature of spectrin (TA≈49.5°C) in order to obtain the differential dielectric spectroscopy data. The complex admittance, Y* = Y’+j.Y”, of the tested suspensions was continuously measured and separated into its real (Y’) and imaginary (Y”) parts using Solartron 1260 Impedance Frequency Analyzer.
Results: At pre-hemolytic concentrations, each drug inhibited these two relaxations, predominantly the γ1sp relaxation. The results could be interpreted in terms of a sigmoid effect of the drugs on the spectrin-ankyrin-band 3 bridge severing it at concentration just prior to the start of massive hemolysis.
Conclusions: The study points at the possible mechanism of erythrocyte damage after treatment with phenothiazine drugs at prehemolytic concentrations. This is probably due to the disruption of the bridges between the phospholipid bilayer and the submembrane spectrin network.

Purpose: Cryptococcal infection in the Central Nervous System (CNS) is frequently seen in human immunodeficiency virus (HIV) patients and others with low immunity. CNS cryptococcoma in immunocompetent patients is rare. We present a case of CNS cryptococcoma in an immunocompetent patient and review literature.
Methodology: A 62-year-old, HIV negative, immunocompetent female patient with no known chronic illness, presented with 5 months’ history of a progressive headache, associated with on and off episodic generalized convulsions. She had been to several hospitals before referral to our center with a diagnosis of a brain tumor on CT scan imaging. Before this and despite a negative CSF analysis result, she had received treatment for bacterial meningitis with no success.
Findings: At Mbarara Regional Referral Hospital (MRRH), she had surgery with excision biopsy which showed features consistent with cryptococcosis on histology. The patient had a successful adjuvant treatment with antifungal drugs following surgery.
Unique Contribution to Theory, Practice and Policy: The diagnosis of a CNS cryptococcal infection in an immunocompetent patient and its successful treatment by including surgery, were both unusual. Fatal postsurgical outcomes have been reported by other authors who favor a totally conservative approach to the treatment of this lesion.

On the concept of internationalisation: Towards a socially just research collaboration between the UK and MENA countries
Authors: Abbas Andrea , Gao Jie , Ismail Gihan 
Published: October 2023

This paper argues for a wider range of critical perspectives to be bought to bear on the phenomenon of internationalisation. We suggest the role of internationalisation research should be to promoting reciprocity and respect for global knowledges. It was developed as a discussion piece for the Re-Knox Conference in Cairo (August 2022). It is based on a process of independent and co-reflexivity regarding three of the authors research projects. It conveys and illustrates three principles regarding theory and method that we found valuable for understanding how research that builds a more sustainable, equitable and cooperative form of higher education could be developed. The goal is to unpick and transform the destructive, exploitative, and negative relationships that are embedded in internationalisation for all parties involved

Abstract. As the theoretical upper bound of evapotranspiration (ET) or water use by ecosystems, potential ET (PET) has always been widely used as a variable linking a variety of disciplines, such as climatology, ecology, hydrology, and agronomy. However, substantial uncertainties exist in the current PET methods (e.g., empiric models and single-layer models) and datasets because of unrealistic configurations of land surface and unreasonable parameterizations. Therefore, this study comprehensively considered interspecific differences in various vegetation-related parameters (e.g., plant stomatal resistance and CO2 effects on stomatal resistance) to calibrate and parametrize the Shuttleworth–Wallace (SW) model for forests, shrubland, grassland, and cropland. We derived the parameters using identified daily ET observations with no water stress (i.e., PET) at 96 eddy covariance (EC) sites across the globe. Model validations suggest that the calibrated model could be transferable from known observations to any location. Based on four popular meteorological datasets, relatively realistic canopy height, time-varying land use or land cover, and the leaf area index, we generated a global 5 km ensemble mean monthly PET dataset that includes two components of potential transpiration (PT) and soil evaporation (PE) for the 1982–2015 time period. Using this new dataset, the climatological characteristics of PET partitioning and the spatiotemporal changes in PET, PE, and PT were investigated. The global mean annual PET was 1198.96 mm with PT/PET of 41 % and PE/PET of 59 %, controlled moreover by PT and PE of over 41 % and 59 % of the globe, respectively. Globally, the annual PET and PT significantly (p<0.05) increase by 1.26 and 1.27 mm yr−1 over the last 34 years, followed by a slight decrease in the annual PE. Overall, the annual PET changes over 53 % of the globe could be attributed to PT, and the rest to PE. The new PET dataset may be used by academic communities and various agencies to conduct climatological analyses, hydrological modeling, drought studies, agricultural water management, and biodiversity conservation. The dataset is available at https://doi.org/10.11888/Terre.tpdc.300193 (Sun et al., 2023).
