The Effects of Creative Experience-Centered Environmental Education on Emotional Intelligence of Elementary School Students
This study was carried out with the purpose of verifying the impact that experience centered environmental education with an emphasis on communing with the surrounding natural environment could have on elementary school student`s emotional intelligence.
This experiment was carried out on a group of 55 students (29 in the control and 26 in the experimental group) from two 4th grade classes. Following the development of experience-oriented lessons on environmental education based on a 'teaching and learning' model of environmental education for this study, the lessons were applied for 30 lessons and over a 16-week period. The experiment was carried out using a checklist of emotional intelligence and administered by a pretest-posttest method.
The results of the study, signs of improvement were recognized in ability to recognize self-emotion (pă.05), ability to control self-emotion (pă.05), interpersonal skills with a significant increase (pă.01), self-synchronization ability (p=0.183), and empathic ability (p=0.058).
Therefore, it is evident that a positive effect on the increase of emotional intelligence in elementary school students is achieved through creative experience-oriented environmental education
A Photometric and Spectroscopic Study of the Short-Period Algol EW Bo\"{o}tis with a Sct Pulsator
In this paper, we present TESS photometry and high-resolution spectra of the
short-period Algol EW Boo. We obtained double-lined radial velocities (RVs)
from the time-series spectra and measured the effective temperature of the
primary star as = 8560 118 K. For the orbital period
study, we collected all times of minima available for over the last 30 years.
It was found that the eclipse timing variation of the system could be
represented by a periodic oscillation of 17.6 0.3 years with a
semi-amplitude of 0.0041 0.0001 d. The orbital and physical parameters
were derived by simultaneously analyzing the TESS light and RV curves using the
Wilson-Devinney (WD) binary star modeling code. The component masses and radii
were showed over 3% precision: = 2.67 0.08 M,
= 0.43 0.01 M, = 2.01 0.02 R, and
= 1.35 0.01 R. Furthermore, multiple frequency
analyses were performed for the light-curve residuals from the WD model. As a
result, we detected 17 pressure-mode pulsations in the region of 40.15 - 52.37
d. The absolute dimensions and pulsation characteristics showed that the
Sct pulsator was the more massive and hotter primary star of the EW

Novel Swine-Origin Influenza A (H1N1) Viral Encephalitis
The World Health Organization declared that a new strain of novel swine-origin influenza A (H1N1) virus was responsible for the pandemic infection in June 2009. We report a case of encephalitis diagnosed as the H1N1 virus infection. We describe a 17-year-old patient who had a seizure attack, diagnosed with a H1N1 virus infection via real time reverse-transcriptase polymerase chain reaction (RT-PCR). The H1N1 virus infection can be causative of the encephalitis, as with other influenza virus infections. Careful monitoring is essential for reducing complications
ABL Genomic Editing Sufficiently Abolishes Oncogenesis of Human Chronic Myeloid Leukemia Cells In Vitro and In Vivo
Chronic myelogenous leukemia (CML) is the most common type of leukemia in adults, and more than 90% of CML patients harbor the abnormal Philadelphia chromosome (Ph) that encodes the BCR-ABL oncoprotein. Although the ABL kinase inhibitor (imatinib) has proven to be very effective in achieving high remission rates and improving prognosis, up to 33% of CML patients still cannot achieve an optimal response. Here, we used CRISPR/Cas9 to specifically target the BCR-ABL junction region in K562 cells, resulting in the inhibition of cancer cell growth and oncogenesis. Due to the variety of BCR-ABL junctions in CML patients, we utilized gene editing of the human ABL gene for clinical applications. Using the ABL gene-edited virus in K562 cells, we detected 41.2% indels in ABL sgRNA_2-infected cells. The ABL-edited cells reveled significant suppression of BCR-ABL protein expression and downstream signals, inhibiting cell growth and increasing cell apoptosis. Next, we introduced the ABL gene-edited virus into a systemic K562 leukemia xenograft mouse model, and bioluminescence imaging of the mice showed a significant reduction in the leukemia cell population in ABL-targeted mice, compared to the scramble sgRNA virus-injected mice. In CML cells from clinical samples, infection with the ABL gene-edited virus resulted in more than 30.9% indels and significant cancer cell death. Notably, no off-target effects or bone marrow cell suppression was found using the ABL gene-edited virus, ensuring both user safety and treatment efficacy. This study demonstrated the critical role of the ABL gene in maintaining CML cell survival and tumorigenicity in vitro and in vivo. ABL gene editing-based therapy might provide a potential strategy for imatinib-insensitive or resistant CML patient

Disruption of nucleocytoplasmic trafficking as a cellular senescence driver
Senescent cells exhibit a reduced response to intrinsic and extrinsic stimuli. This diminished reaction may be explained by the disrupted transmission of nuclear signals. However, this hypothesis requires more evidence before it can be accepted as a mechanism of cellular senescence. A proteomic analysis of the cytoplasmic and nuclear fractions obtained from young and senescent cells revealed disruption of nucleocytoplasmic trafficking (NCT) as an essential feature of replicative senescence (RS) at the global level. Blocking NCT either chemically or genetically induced the acquisition of an RS-like senescence phenotype, named nuclear barrier-induced senescence (NBIS). A transcriptome analysis revealed that, among various types of cellular senescence, NBIS exhibited a gene expression pattern most similar to that of RS. Core proteomic and transcriptomic patterns common to both RS and NBIS included upregulation of the endocytosis-lysosome network and downregulation of NCT in senescent cells, patterns also observed in an aging yeast model. These results imply coordinated aging-dependent reduction in the transmission of extrinsic signals to the nucleus and in the nucleus-to-cytoplasm supply of proteins/RNAs. We further showed that the aging-associated decrease in Sp1 transcription factor expression was critical for the downregulation of NCT. Our results suggest that NBIS is a modality of cellular senescence that may represent the nature of physiological aging in eukaryotes. © 2021, The Author(s).1
