The Effect of Recombinant Anthrax Lethal Toxin on Breast Cancer Cell Motility, Adhesion, and Invasion. (c2020)
Authors:   ,   Lebanese American University, El Chami Dana
Published: July 2022

Breast cancer-related deaths are mostly due to breast cancer invasion and migration to distant secondary regions. Targeting breast cancer cell metastasis is an important therapeutic approach. The mitogen-activated protein kinase (MAPK) pathway is a key cell signaling pathway that plays a major role in cell invasion and migration. Many studies have targeted the MAPK pathway as a way to target cell survival and motility. In this study, we use Lethal Toxin (LT) a potent MAPK inhibitor that selectively inactivates all the kinases in the MAPK pathway. LT proved to affect breast cancer cell migration, adhesion, and invasion. Cells treated with LT showed a significant decrease in motility as seen in 2D time-lapse and wound healing assays. Additionally, cells treated with LT showed an increase in adhesion, decrease in invasion across a collagen matrix, and in increase in Rho A activation. We speculate that LT inhibited cell migration by deregulating the activity of Rho GTPases, proteins known to play a role in cell migration. In this study, we describe the effect of LT as a potential breast cancer cell invasion and motility inhibitor.
Cytotoxicity of arginine deprivation to AML cells is mediated by autophagy / by Fatima Taki . (c2020)
Authors:   ,   Lebanese American University, Taki Fatima
Published: July 2022

In this study, we assess the activation of autophagy in AML cells following arginine deprivation, the mechanism of its activation, and its impact on cell cytotoxicity. Arginine deprivation was induced using a pegylated recombinant human Arginase I [HuArgI(Co)-PEG5000], in which the two Mn2+ ions of the active site have been replaced with Co2+ ions. AML cell lines were tested, and activation of autophagy was determined by staining for autophagosomes on flow cytometry. The impact of autophagy on cell cytotoxicity of arginine deprivation was assessed through inhibition of autophagy using the downstream autophagy inhibitor chloroquine (CQ). [HuArgI(Co)-PEG5000]-induced arginine deprivation led to significant and sustained activation of autophagy starting at 24 hours and lasting up to 120 hours following arginine deprivation in all cell lines. Inhibition of autophagy, using chloroquine, led to a significant decrease in cell cytotoxicity evident at 48 hours and up to 120 hours. This indicates that activation of autophagy in response to arginine deprivation, is leading to AML cell death (death by autophagy). This was further confirmed by the fact that cell death observed following arginine deprivation in AML cells was caspase-independent and nonapoptotic. Moreover, AML cells were shown to overexpress the major key player in the biosynthesis of L-arginine; Argininosuccinate Synthetase-1 (ASS-1) upon arginine deprivation without it conferring resistance to death by autophagy induced by HuArgI(Co)-PEG5000. Addition of the ROS scavenger N-acetyl-cysteine (NAC) repressed the autophagic response and reversed cytotoxicity of arginine deprivation to AML cells, indicating that the activation of autophagy is induced following ROS generation. Finally, our study demonstrates that in AML cells, arginine deprivation induces autophagy activation leading to cell death irrespective the overexpression of ASS-1. We have also shown that the activation of autophagy and the subsequent death by autophagy of AML cells is induced through generation of ROS.
The Role of Cdc42 and the Cross-talk with RhoA/RhoC during Invadopodia Formation and Invasion in Glioblastoma Multiforme. (c2020)
Authors:   ,   Lebanese American University, Maalouf Hiba
Published: July 2022

Glioblastoma multiforme (GM) is a malignant grade IV tumor characterized by its ability to rapidly proliferate and infiltrate into the normal neighboring brain tissue. Tumor invasion and metastasis remain the major cause of death in patients with GM. The Rho family of GTPases is a key regulator of cell migration and invasion. Previous work in our lab has shown that the well characterized members of this family, Cdc42, RhoA and RhoC positively regulate 2D motility in GM. In this study, we sought to investigate the role of these three Rho GTPases in 3D migration, particularly in the formation of invadopodia which are the actin rich structures required for the degradation of the extracellular matrix. Our findings showed that Cdc42 and RhoA are essential for invadopodia formation. The depletion of RhoC did not affect the invadopodia number which implies that it might regulate invadopodia formation through a different mechanism. Our data also showed that Cdc42, but not RhoA and RhoC, localizes to the invadopodia structure. To better understand the signaling mechanism underlying Cdc42 positive regulation of invadopodia, we examined the effect of Cdc42 knockdown on the activation of RhoA. We found that Cdc42 depletion decreased RhoA activation which suggests that Cdc42 might be operating upstream of RhoA and regulating invadopodia formation through RhoA. We also investigated the effect of Cdc42 and RhoC on MMP2 and MMP9 expression. Our results showed that Cdc42 and RhoC knockdown decreased MMP9 expression levels while only RhoC depletion reduced MMP2 expression. Overall, our findings suggest that, in glioblastoma, Cdc42, RhoA and RhoC regulate the formation of invadopodia differently.
The Activation Kinetics and Crosstalk of RhoGTPases. (c2020)
Authors:   ,   Lebanese American University, Al Haddad Maria
Published: July 2022

Fluorescence or Förster resonance energy transfer (FRET) is a quantitative transfer of energy between two fluorescent moieties in proximal distance, between 10Å and 100Å. The energy transfer is useful in studying direct molecular interactions and activation. Hence, FRET led to the design of biosensors. Biosensors are two chromophores linked to 2 entities, joined together by a linker which determines their juxtaposition relative to each other, and thus the amount of energy transfer. By exciting one chromophore and observing the emission of the other, one can determine the activation and binding of certain proteins. Using this technique, we are studying the crosstalk of Rho GTPases in different cell lines, with a focus on RhoA, RhoC, Cdc42 and Rac1. We first showed how RhoGTPase activity is concentrated at the cell periphery. We also found Cdc42 activation to be concentrated at invadopodia and membrane ruffles. Then, we investigated the interplay between Cdc42 and RhoA by knocking down one target and studying the activation of the other in brain cancer cells, and vice versa. The results indicate an antagonistic relationship between the two in one glioblastoma cell line and a cooperative relation in the other. As for the interplay of RhoA and RhoC with Rac1, we found out that RhoA regulates the expression of Rac1 in cells, whereas RhoC has no effect on Rac1 expression or activity levels. Additionally, we wanted to use FRET so test the regulation of RhoGTPases by upstream effectors such as STARD13. We checked for the effect of STARD13 knockdown on Cdc42 activation in lung cancer cells. In the A549 lung cancer cells, the activation of Cdc42 increased as we hypothesized. Altogether these experiments show the efficiency of using FRET as a tool for studying the activation kinetics and dynamics of Rho GTPases.

Authors:   Российский университет дружбы народов, Палеев Д.Л. , Черняев М.Л. ,   Российский университет дружбы народов
Published: July 2022

The increase in demand for coal over the past two years has opened up good prospects for Russian mining companies. The growth of production is hampered by the insufficient capacity of transport corridors, and the extensive development of transport infrastructure against the backdrop of an unstable economy and low tariffs for coal transportation is not profitable. For the effective strategic development of the coal industry, the transport problem is proposed to be solved in close conjunction with the development of coal chemistry. Products of deep coal processing require less transport, they have a lower share of transport costs in the final cost. The article argues that this approach will increase the production and export of coal without a proportional increase in traffic volumes.

On the Pro-oxidant Activity of Curcumin in Lipid Media: A Theoretical Study
Authors: Medina Manuel E. , Trigos Ángel
Published: July 2022

Abstract. In the scientific literature can be found experimental evidence on the pro-oxidant capacity of curcumin through its photosensitizer property; it has been related to biological activities such as the antibacterial and antitumor observed in this molecule; however, the pro-oxidant evidence, little is known about the reaction mechanism involved in the photosensitizing property of curcumin. Thus, it was carried out a study on the photosensitizer capacity of curcumin in lipid media employs the density functional theory. The thermodynamic results showed the remarkable capacity of curcumin to reduce itself through the single electron transfer mechanisms. The kinetic results showed that mechanism type II is the main mechanism, and it showed a total reaction rate constant calculated of 1.69 x 1010 M-1 s-1 on the photosensitizer capacity of curcumin in lipid media. The reactions related to the mechanism type I was not feasible; hence, these reactions were not contributed to the photosensitizer capacity of curcumin in lipid media. Finally, these results support the idea that the curcumin in lipid media is a pro-oxidant molecule capable of generating the 1O2 molecule and, consequently, could cause oxidative damage through the photooxidative reactions.
 
Resumen. En la literatura se puede encontrar evidencia experimental sobre la capacidad pro-oxidante de la curcumina a traves de su propiedad fotosensibilizadora, esta propiedad se ha relacionado con la actividad antibacteriana y antitumoral observada en esta molécula; a pesar de la evidencia experimental, poco se conoce sobre el mecanismo de reacción involucrado en la propiedad fotosensibilizadora de la curcumina. De acuerdo con lo anterior, se llevó a cabo el estudio de la capacidad fotosensibilizadora de curcumina en medio lipídico, empleando la teoría de funcionales de la densidad. Los resultados termodinámicos mostraron la extraordinaria capacidad de la curcumina para reducirse a través de reacciones de transferencia electrónica. Los resultados cinéticos mostraron que el mecanismo tipo II es el más importante en la capacidad fotosensibilizadora de la curcumina en medio lipídico, mostrando una constante de velocidad de 1.69 x 1010 M-1 s-1. La reacción relacionada con el mecanismo tipo I no se lleva a cabo; por lo tanto, estas reacciones no contribuyen en la capacidad fotosensibilizadora de la curcumina en medio lipídico. Finalmente, estos resultados apoyan la idea de que la curcumina en medio lipídico es una molécula prooxidante capaz de inducir el estrés oxidativo por la generación de la molécula de 1O2 y de esta forma, generar daño oxidativo a estructuras celulares importantes a través de reacciones de fotooxidación.

The sample consisted of 63 adolescents from the centres for children and families and 94 adolescents from complete families, all of them aged from 15 to 20 (M = 16,9; SD = 1,32). To identify self-esteem, RSES – Rosenberg Self-Esteem scale (1965) was used and to identify values, PVQ – Portrait Value Questionnaire by Schwartz et al. (2001) was used. We discovered that there are significant differences between research groups in values universalism (p < 0,001; d = 0,95), self-direction (p < 0,001; d = 0,8), conformity (p < 0,05; d = 0,34), security (p < 0,01; d = 0,5) and benevolence (p < 0,001; d = 0,587), while we did not find statistically significant (p > 0,05) difference between groups in values: power, success, stimulation, hedonism and tradition. Adolescents growing up in families scored higher than adolescents growing up in centres for children and families in values universalism, self-direction, conformity, security and benevolence. We find a significant difference in self-esteem (p < 0,01; d = 0,461) between adolescents growing up in centres for children and family and those from complete families, whereas adolescents growing up scored higher.
Responsible Artificial Intelligence in Government: Development of a Legal Framework for South Africa
Authors: Brand Dirk
Published: July 2022

Various international guideline documents suggest a human-centric approach to the development and use of artificial intelligence (AI) in society, to ensure that AI products are developed and used with due respect to ethical principles and human rights. Key principles contained in these international documents are: transparency (explainability), accountability, fairness and privacy. Some governments are using AI in the delivery of public services, but there is a lack of appropriate policy and legal frameworks to ensure responsible AI in government. This paper reviews recent international developments and concludes that, an appropriate policy and legal framework must be based on the key principles contextualised to the world of AI. A national legal framework alone is not sufficient and should be accompanied by a practical instrument, such as an algorithm impact assessment, aimed at reducing risk or harm. Recommendations for a possible South African legal framework for responsible AI in government are proposed.

Intellectual property is the result of human thought that is realized in the form of real works, and is not just an idea, idea, concept but the most important thing is its realization. Some people have ideas but are not necessarily able to realize these ideas in a tangible form. In connection with the above, the younger generation, including high school students, generally have many ideas, but not all of them have been realized. Therefore, this community service aims to provide an introduction and understanding related to intellectual property, to beginners, namely students from the Islamic Integrated High School (SMA IT) Putri AL Hanif in Cilegon City. The introduction and understanding of Intellectual Property need to be introduced to the students of SMA IT Putri Al Hanif from an early age by implementing Intellectual Property completely and correctly, there is a great opportunity for students and students to produce quality and highly competitive works. With this service activity, the school's awareness of the importance of Intellectual Property arises and fosters motivation to be creative and innovate. In general, Intellectual Property has not been exploited to its full potential, both in higher education and in secondary schools.

The results of this community service can provide understanding to students, especially SMA IT Putri Al Hanif Cilegon City regarding Intellectual Property material which includes Communal Intellectual Property (Traditional Knowledge, Traditional Cultural Expressions, and Geographical Indications), Personal Intellectual Property (owned by industry). In the provision of service material, it is divided into 3 different classes, namely Language Class, Science and Social Sciences. They are very enthusiastic in listening, understanding, and discussing the introduction of intellectual property (IP). Therefore, there is a follow-up from the school to improve the work of its students so that the work is given legal protection through the intellectual property registration application process.

Published: July 2022

Vertical motions, especially in the active continental margins such as Kuril-Kamchatka transition zone, are still pure studied. One of the factors significantly affecting the amplitudes and directions of vertical motions is mantle convections. Estimates of the amplitudes of vertical motions in region have been obtained by means of numerical modeling of the mantle convection made by the method of finite elements. The values of emergences in the area of Sakhalin Island and the Kuril Ridge from 0–3 to 13 m were obtained with the accepted rates of mantle convection from 1 to 5 mm/year. The results obtained should be taken into account when reconstructing neotectonic history of the region and assessing the geodynamic situation in the region of the Sea of Okhotsk.

Исследования по совершенствованию технологии возделывания люцерны синей сорта Талисман проводили в 2017 – 2019 гг. в Волгоградской области на светло-каштановых почвах Волго-Донского междуречья с содержанием гумуса в пахотном слое 1,7 %. Изучали 3 приёма основной обработки почвы: 1) отвальную на глубину 0,20 – 0,22 м; 2) плоскорезную на глубину 0,28 – 0,30 м; 3) отвальную на глубину 0,20 – 0,22 м с углублением до 0,38 – 0,40 м. В среднем за вегетацию в корнеобитаемом слое почвы 0 – 0,4 м плотность почвы в 1-м варианте составила 1,16 т/м3, во 2-м варианте она была такой же, а в 3-м варианте — 1,11 т/м3; порозность: в 1-м варианте — 56,8 %, во 2-м варианте она была такой же, в 3-м варианте — 58,7 %. Урожайность зелёной массы люцерны в среднем за 3 года была наибольшей в 3-м варианте — 50,6 т/га, а наименьшей — в 1-м варианте — 48,8 т/га. Для возделывания люцерны предпочтительна отвальная обработка почвы на глубину 0,20 – 0,22 м с углублением до 0,38 – 0,40 м.
Влияние физиологического состояния коров на выведение радионуклидов при скармливании лекарственных растений
Authors: Лашкова Татьяна Борисовна , Петрова Галина Васильевна
Published: July 2022

На современном этапе ведения сельского хозяйства возникает проблема поиска эффективных, практичных и недорогих препаратов и добавок для снижения радиоактивного загрязнения организма сельскохозяйственных животных. Исследовано воздействие лекарственных растений при скармливании животным на экскрецию радионуклидов через желудочно-кишечный тракт и почки, а также то, как физиологическое состояние коров влияло на этот процесс. В результате эксперимента установлено, что введение в рацион лактирующих животных всех видов и доз растительных добавок положительно повлияло на выведение как калия-40, так и цезия-137. Среднее значение концентрации цезия-137 было на 3,2 Бк/кг выше по отношению к контролю в кале и на 3,4 Бк/кг — в моче; калия-40 — на 33,1 Бк/кг в кале и на 28,49 Бк/кг в моче. То, что на последних сроках беременности скорость обмена веществ увеличивается практически в 2 раза с преобладанием именно усвоения, сказалось на метаболизме радионуклидов. Особенно это видно по концентрации калия-40, который, по показателям контрольных групп, очень активно накапливался в организме, но и также активно выводился.
