Published: August 2021

Indonesia is one of the positive countries for the corona virus (Covid-19). Experts cite several reasons for the increasing number of cases, one of which is the attitude of the public who careless about minimizing contact between people, the lack of sanctions for violations of self-quarantine, and the lack of location information that the community must avoid. The attitude of caring society, especially education actors, is certainly one of the important things that needs attention. Environmental care and responsibility are character values that need to be developed. Students can get character education through the learning process and learning resources, one of which is textbooks. The purpose of this study was to determine whether there is an integration of character values and what is the percentage of integration of character values in high school chemistry textbooks that have been used by teachers in learning, especially the character of environmental care and responsibility.

Published: August 2021

The emergence of the 4.0 industrial revolution requires university graduates to have 21st-century thinking skills that can support them to compete globally. However, the low 21st-century thinking skills of prospective teachers in the group of ways of thinking (critical thinking, problem-solving, and decision making) make the learning process should be able to train and develop these thinking skills. One way to train prospective teachers' 21st-century thinking skills is through the textbooks used in lectures. This study aims to develop textbooks based on socioscientific issues on the topic of Sustainable Development Goals (SDGs). This study used the RD research method with ADDIE design which is composed of 5 stages: Analyze, Design, Develop, Implement, and Evaluate. textbooks were applied at the implementation stage by involving second-semester prospective teachers who contract Environmental Knowledge courses. The instruments used in this study included textbook validation sheets and essay tests. The validation results were analyzed using descriptive analysis, while the essay test results were analyzed using SPSS. The results of the study showed that the socioscientific issues-based textbooks on the SDGs topic received a very good expert assessment and had met the standards of the appropriateness of the content, language, graphics, presentation, and socioscientific issues. Prospective teachers' 21st-century thinking skills in the group of the way of thinking  also improved significantly after using socioscientific issues-based textbooks. These indicated that the textbooks which have been developed were effective in practicing the 21st-century thinking skills of prospective teachers.

Endoscopic treatment of complex multiloculated hydrocephalus in children, steps that may help to decrease revision rate
Authors: Elkheshin Sherif Elsayed , Bebars Mohamed
Published: August 2021

Background:

Multiloculated hydrocephalus (MLH) is associated with increased intracranial pressure, with intraventricular septations, loculations, and isolation of parts of the ventricular system. Search continues for ideal surgical remedy capable of addressing the dimensions of the problem. We aimed to evaluate endoscopic septal fenestration and pellucidotomy combined with proximal shunt tube refashioning and further advancement into isolated loculations of the ventricular system containing choroid plexus.

Methods:

This retrospective study was conducted on 55 patients with symptomatic complex MLH who underwent endoscopic surgery. The collected data included patients’ age, gender, presenting manifestations, operative details, rate of remission of preoperative clinical and imaging signs, postoperative complications, redo surgery, or extra shunt hardware insertion. Patients were divided into Group A (underwent the standard technique of endoscopic multiseptal wide fenestration and final ventriculoperitoneal shunt insertion) and Group B (modified technique by adding extra side ports along the proximal shunt hardware).

Results:

Groups A and B included 25 and 30 patients, respectively. The percentage of patients showing improvement of almost all manifestations was higher in Group B compared to Group A, with no significant difference (P> 0.05). Group B had lower rate of complications (20% vs. 36%,P= 0.231), insertion of two shunts (16.7% vs. 20%,P= 1.000), and redo surgery (20% vs. 44%,P= 0.097).

Conclusion:

The modified technique was associated with better outcomes in terms of the use of single shunt and redo surgery. Launching randomized clinical trials to compare the two techniques are recommended to ascertain the efficacy of the modified technique.

Description du sujet. Plantago albicans est une psammophyte pastorale dont la variabilité morphologique est observable sur le terrain. L’évaluation de l’influence des conditions du milieu sur les caractères morphologiques de l’espèce a été étudiée. Objectifs. L’objectif du présent travail est d’analyser la variabilité morphologique de quelques populations de P. albicans dans la région du Sud-Oranais (Ouest algérien). Méthode. Deux-cents-quarante individus répartis en 12 populations ont été récoltés le long d’un transect nord-sud et sont issus de biotopes différents. Ces individus ont fait l’objet de mesures morphométriques sur lesquelles des analyses univariées et multivariées sont appliquées. Résultats. L’étude a révélé une variabilité inter-populations qui serait liée à la combinaison de facteurs stationnels et à la diversité biologique des biotopes. Des coupes anatomiques réalisées sur des axes aphylles érigés entre la rosette de feuilles et la racine ont permis de conclure à une structure anatomique adaptée de la tige de P. albicans qui, au fur et à mesure de la croissance de la rosette, surélève la partie feuillée photosynthétique évitant l’ensevelissement de la plante lors d’un ensablement trop important. Conclusions. La variabilité des caractères morphologiques de P. albicans (longueur et largeur de la feuille, longueur de la hampe florale, de l’épi et de l’axe aphylle) semble traduire une plasticité phénotypique, c'est-à-dire une aptitude à exprimer le phénotype qui s’accommode le mieux aux conditions du milieu et souligne la capacité de l’espèce à occuper des milieux fortement ensablés.

Description of the subject. Given the current low price of milk, a lot of producers have decided to process their milk into products with a higher added-value, including butter. However, all milks are not suitable to be transformed into butter. It would thus be useful to be able to predict milk processing properties. Objectives. The aim of this paper was to study the ability of milk to be processed into butter using infrared spectrophotometry. Method. A normalized protocol for the production of butter was developed. Milk samples (n = 110) collected between 2013 and 2016 were analyzed by near and medium infrared spectrometry (315 spectra). Butter samples were also analyzed by visible-near infrared spectrometry (220 spectra). Composition of the products was subsequently assessed using validated prediction equations. Principal components analyses were performed to discriminate samples. Results. Butter properties seemed to be influenced by seasons and feedings. Water content and color parameters could be predicted on the basis of butter infrared spectra. Conclusions. It was possible to correlate butter characteristics with milk properties. However, it was not possible to predict butter characteristics on the basis of milk near infrared spectra. It could be interesting to try predictions from milk medium infrared spectra.

Sudden withdrawal of some drugs leads to withdrawal issues. We describe a baby girl who was indirectly exposed to venlafaxine as her mother was administered this drug during pregnancy for treatment of depression. The subject presented with involuntary movement of the limbs. The mother had also encountered similar scenario along with some other symptoms after she suddenly discontinued her medication. The symptoms of the mother completely resolved a few hours after the she took another dose of venlafaxine. The baby was kept under observation and recovered completely without any intervention. We suggest that healthcare professionals should be aware that patients may require tapering of anti-depressants before discontinuation.
Paralogous synthetic lethality underlies genetic dependencies of the cancer-mutated gene STAG2
Authors: Bailey Melanie L , Tieu David , Habsid Andrea , Tong Amy Hin Yan , Chan Katherine , Moffat Jason , Hieter Philip
Published: August 2021

STAG2, a component of the mitotically essential cohesin complex, is highly mutated in several different tumour types, including glioblastoma and bladder cancer. Whereas cohesin has roles in many cancer-related pathways, such as chromosome instability, DNA repair and gene expression, the complex nature of cohesin function has made it difficult to determine how STAG2 loss might either promote tumorigenesis or be leveraged therapeutically across divergent cancer types. Here, we have performed whole-genome CRISPR-Cas9 screens for STAG2-dependent genetic interactions in three distinct cellular backgrounds. Surprisingly, STAG1, the paralog of STAG2, was the only negative genetic interaction that was shared across all three backgrounds. We also uncovered a paralogous synthetic lethal mechanism behind a genetic interaction between STAG2 and the iron regulatory gene IREB2. Finally, investigation of an unusually strong context-dependent genetic interaction in HAP1 cells revealed factors that could be important for alleviating cohesin loading stress. Together, our results reveal new facets of STAG2 and cohesin function across a variety of genetic contexts.
Statistical guidelines for quality control of next-generation sequencing techniques

Published: August 2021

More and more next-generation sequencing (NGS) data are made available every day. However, the quality of this data is not always guaranteed. Available quality control tools require profound knowledge to correctly interpret the multiplicity of quality features. Moreover, it is usually difficult to know if quality features are relevant in all experimental conditions. Therefore, the NGS community would highly benefit from condition-specific data-driven guidelines derived from many publicly available experiments, which reflect routinely generated NGS data. In this work, we have characterized well-known quality guidelines and related features in big datasets and concluded that they are too limited for assessing the quality of a given NGS file accurately. Therefore, we present new data-driven guidelines derived from the statistical analysis of many public datasets using quality features calculated by common bioinformatics tools. Thanks to this approach, we confirm the high relevance of genome mapping statistics to assess the quality of the data, and we demonstrate the limited scope of some quality features that are not relevant in all conditions.

The research model and hypotheses in this study were constructed based on the self-control theory and by reviewing previous research. This research distributed questionnaires to 207 college students from a university in Guangzhou, China to obtain relevant data. Mediation analysis was employed to test the four hypotheses drawn from empirical and conceptual research. The results of this research showed that first, the longer the exercise duration of college students, the higher the level of their self-control, thus exercise duration has a significant positive impact on self-control. Second, increasing the exercise duration of college students had no effect on their mobile phone dependence. Third, the higher the level of self-control, the lower the dependence on mobile phones, thus signifying that self-control has significantly negative impact on mobile phone dependence. Fourth, self-control plays a mediating role in the effect of exercise duration on mobile phone dependence. In conclusion, the longer the exercise duration of college students, the higher the level of self-control, in which it is able to significantly reduce the dependence on mobile phones.
