Abstract
Mergers of galaxy clusters are the most energetic events in the universe, driving shock and cold fronts, generating turbulence, and accelerating particles that create radio halos and relics. The galaxy cluster CL 0217+70 is a remarkable late-stage merger, with a double peripheral radio relic and a giant radio halo. Chandra detects surface brightness (SB) edges that correspond to radio features within the halo. In this work, we present a study of this cluster with Nuclear Spectroscopic Telescope Array and Chandra data using spectro-imaging methods. The global temperature is found to be kT = 9.1 keV. We set an upper limit for the inverse Compton (IC) flux of ∼2.7 × 10−12 erg s−1 cm−2, and a lower limit to the magnetic field of 0.08 μG. Our local IC search revealed a possibility that IC emission may have a significant contribution at the outskirts of the radio halo emission and on/near shock regions within ∼0.6 r
500 of clusters. We detected a “hot spot” feature in our temperature map coincident with an SB edge, but our investigation on its origin is inconclusive. If the “hot spot” is the downstream of a shock, we set a lower limit of kT > 21 keV to the plasma that corresponds to



∼2. We found three shock fronts within 0.5 r
500. Multiple weak shocks within the cluster center hint at an ongoing merger activity and continued feeding of the giant radio halo. CL 0217+70 is the only example hosting these secondary shocks in multiple form.
On the Spatial Distribution of Polarization and Color of a Distant Comet C/2017 K2 (PanSTARRS)
Authors: Zubko Evgenij , Videen Gorden 
Published: January 2023

Abstract
Comet C/2017 K2 (PanSTARRS) was observed at two wavelengths using two different-sized apertures in two measurement campaigns. We find that all the observations can be interpreted using a two-component mixture of dust composed of Mg-rich silicates and amorphous carbon. The modeling suggests a slight increase in the absorption of the refractory component at shorter wavelengths, which is consistent with the optical properties of Mg-rich silicates, and a change in the size distribution as a function of distance from the cometary nucleus, a result of smaller particles accelerating more rapidly from the expanding-gas and radiative-pressure forces.

Abstract
NK cells are major effector cells involved in the elimination of early tumors and prevent metastasis. They often have an impaired function in patients with cancer. Preclinical studies have demonstrated NK cell activation as the adjunctive effect of invariant NKT (iNKT) cells. Activation of iNKT cells after administration of the glycolipid ligand α-galactosylceramide, loaded with CD1d-expressing human PBMC-derived APCs (APC/Gal), is an attractive cancer therapy to optimize the use of NK cells. However, the subsets of NK cells that are activated following iNKT cell activation as well as the period of NK cell activation remain unclear. In this study, we report that the granzyme B–expressing NK cell response in postoperative lung cancer patients was enhanced 49 d after administration of APC/Gal in a phase II study. We found maximum IFN-γ production on day 49 in 13 out of 27 APC/Gal-treated patients. On day 49, 14 out of 27 patients (51.9%) had higher IFN-γ production by iNKT cells (&gt;6-fold higher than the baseline level). This increment significantly correlated with granzyme B–expressing NK cells. Although IFN-γ production was lower in patients in the nontreated group, we detected maximum IFN-γ production 12 mo after the resection of lung cancer (9 out of 29 patients [31%]). These findings suggest that elimination of cancer cells leads to increased NK cell function, which can be further enhanced by APC/Gal therapy.
CD19 Is Internalized Together with IgM in Proportion to B Cell Receptor Stimulation and Is Modulated by Phosphatidylinositol 3-Kinase in Bone Marrow Immature B Cells

Published: January 2023

Abstract
Newly generated immature B cells that bind self-antigen with high avidity arrest in differentiation and undergo central tolerance via receptor editing and clonal deletion. These autoreactive immature B cells also express low surface levels of the coreceptor CD19, a key activator of the PI3K pathway. Signals emanating from both CD19 and PI3K are known to be critical for attenuating receptor editing and selecting immature B cells into the periphery. However, the mechanisms that modulate CD19 expression at this stage of B cell development have not yet been resolved. Using in vivo and in vitro models, we demonstrate that Cd19 de novo gene transcription and translation do not significantly contribute to the differences in CD19 surface expression in mouse autoreactive and nonautoreactive immature B cells. Instead, CD19 downregulation is induced by BCR stimulation in proportion to BCR engagement, and the remaining surface IgM and CD19 molecules promote intracellular PI3K-AKT activity in proportion to their level of expression. The internalized CD19 is degraded with IgM by the lysosome, but inhibiting lysosome-mediated protein degradation only slightly improves surface CD19. In fact, CD19 is restored only upon Ag removal. Our data also reveal that the PI3K-AKT pathway positively modulates CD19 surface expression in immature B cells via a mechanism that is independent of inhibition of FOXO1 and its role on Cd19 gene transcription while is dependent on mTORC1.

Published: January 2023

Abstract
Atopic dermatitis (AD) is a common chronic skin disease. Although generally thought to be a disease of T-cell dysregulation, recent studies have suggested that immune dysregulation of NK cells is also important. Killer cell Ig-like receptors (KIRs) are involved with NK cell regulation. The Pediatric Eczema Elective Registry is a U.S. nationwide longitudinal cohort with up to 10 y of follow-up in which 655 children had DNA available for full allelic KIR sequencing. Every 6 mo, AD activity was reported by Pediatric Eczema Elective Registry children. Using generalized estimating equations, we evaluated the association of KIR allelic variation in concert with known HLA binding ligands and whether the child reported AD in “remission” (no skin lesions and not using AD medication). KIR2DS4*001:01 (odds ratio 0.53, 95% CI [0.32, 0.88]) and KIR2DL4*001:02 (0.54, [0.33, 0.89]) in the presence of C*04:01 had the largest effect on decreasing the likelihood of AD remission. The haplotype KIR 2DL4*001:02 ∼ 2DS4*001:01 ∼ 3DL2*002:01 (0.77, [0.60, 0.99]) was also associated with a decreased likelihood of AD remission. Our findings add to the general body of evidence of a growing literature on the importance of NK cells with respect to the immunopathogenesis and natural history of AD.

Published: January 2023

Objective
To critically assess the literature focused on sex-specific trajectories in physical characteristics associated with anterior cruciate ligament (ACL) injury risk by age and maturational stage.

Data Sources
PubMed, CINAHL, Scopus, and SPORTDiscus databases were searched through December 2021.

Study Selection
Longitudinal and cross-sectional studies of healthy 8- to 18-year-olds, stratified by sex and age or maturation on ≥1 measure of body composition, lower extremity strength, ACL size, joint laxity, knee-joint geometry, lower extremity alignment, balance, or lower extremity biomechanics were included.

Data Extraction
Extracted data included study design, participant characteristics, maturational metrics, and outcome measures. We used random-effects meta-analyses to examine sex differences in trajectory over time. For each variable, standardized differences in means between sexes were calculated.

Data Synthesis
The search yielded 216 primary and 22 secondary articles. Less fat-free mass, leg strength, and power and greater general joint laxity were evident in girls by 8 to 10 years of age and Tanner stage I. Sex differences in body composition, strength, power, general joint laxity, and balance were more evident by 11 to 13 years of age and when transitioning from the prepubertal to pubertal stages. Sex differences in ACL size (smaller in girls), anterior knee laxity and tibiofemoral angle (greater in girls), and higher-risk biomechanics (in girls) were observed at later ages and when transitioning from the pubertal to postpubertal stages. Inconsistent study designs and data reporting limited the number of included studies.

Conclusions
Critical gaps remain in our knowledge and highlight the need to improve our understanding of the relative timing and tempo of ACL risk factor development.

Тенденция эффективности профилактических мероприятий путем коррекции психологического стресса у детей на стоматологическом приёме
Authors: Ортикова Наргиза 
Published: January 2023

В данной статье рассматриваются тенденции эффективности профилактических мероприятий путем коррекции психологического стресса у детей на стоматологическом приёме, описываются признаки эмоциональной тревожности детей, анализируются возможные причины негативного отношения детей к лечению и, по-видимому, пациенты с высоким страхом и беспокойством, более чувствительны к боли. Кроме того, беспокойство во время лечения зубов мешает ребенку полностью сотрудничать со стоматологом, что приводит к потере время для стоматолога, лишним трудностям при выполнении стоматологических процедур и неудовлетворительным результатам. В исследовании приняли участие 100 детей в возрасте от 6 до 15 лет, которые обратились за стоматологической помощью в Самаркандскую специализированную детскую стоматологическую поликлинику. Анализ степени тревожности детей проводился по шкале Франкла, Кораха DAS, уровню артериального давления и частоте сердечных сокращений. По результатам обследования по данным методикам детей разделили на две группы: основную и контрольную. Охарактеризовали поведение детей с разным уровнем тревожности в зависимости от причины обращения. Сравнили эмоциональное состояние детей, с которыми проводилась предварительная беседа перед посещением врача, с группой детей, у которых не проводилась психологическая коррекция. На основании этих исследований нами были предложены методы выявления, профилактики и регуляции существующего психоэмоционального напряжения детей на стоматологическом приёме.

Published: January 2023

Purpose: The purpose of the study was to determine whether gaps exist in the Kenyan journalism training thatare now filled by other professionals.Materials and methods: The three study sites were local FM radio stations - Radio Citizen, Radio Jambo, and Radio Maisha. Using a 2014 Media Council of Kenya study of radio talk shows in Kenya as a background,the thesis placed more emphasis on the radio presenters and their content. The study applied Social Responsibility Theory which posits that media should be more responsible and accountable to the society. The study employed a descriptive survey using qualitative and quantitative approaches. In this study, four presenters, two key personnel from the Media Council of Kenya were interviewed. as well as a sample of their radio talk show content.Results: The media council of Kenya lacked the capacity to ensure that only trained radio broadcast journalists were hired by media houses. In addition, despite MCK having developed a curriculum for middle level journalism training institutions, its impact in standardising training had been negligible.Recommendations: The study recommended improvement of the journalism curriculum as well as embracing of the MCK curriculum by middle level colleges. Key words: journalism, gaps, training, other professionals
