Este artigo revisa os recentes avanços no tratamento do melanoma avançado e metastático, com foco em imunoterapias, terapias direcionadas e abordagens cirúrgicas. O tebentafusp demonstrou benefícios significativos na sobrevida global de pacientes com melanoma uveal metastático, especialmente entre os HLA-A*02:01 positivos, sugerindo seu potencial como opção terapêutica de primeira linha. O pembrolizumabe, usado como adjuvante em estágios iniciais de melanoma ressecado, mostrou-se eficaz na redução do risco de metástase à distância e recorrência. A combinação de ipilimumabe e nivolumabe também apresentou alta eficácia no tratamento de metástases cerebrais de melanoma, superando as taxas de sobrevida de terapias convencionais. Para melanomas raros, como o melanoma vaginal, a cirurgia permanece central, enquanto a imunoterapia é limitada pelo custo. Estudos com encorafenibe e binimetinibe indicam benefício duradouro em pacientes com mutação BRAF, e o uso de biomarcadores do microbioma surge como uma área promissora para otimizar respostas à imunoterapia. Este conjunto de estudos amplia as opções terapêuticas e propõe estratégias personalizadas, apesar dos desafios econômicos e de acesso.

AdenoCure 3X: Establishing a Sensitized Cancer Cell Model to Accelerate Novel Drug Discovery
Authors: Tan Ee Wern , Tan Kuan Onn , Goh Bey Hing
Published: November 2024

Cancer is a major cause mortality globally, and chemotherapy is frequently employed as a treatment for cancer. Regrettably, cancers possess the ability for developing resistance to conventional treatments, and the rising recurrence of these drug-resistant cancers requires further research and the advancement of treatment approaches. To address the growing challenge of chemoresistance, this study presents a novel approach for developing a sensitized cancer cell model using AdenoCure 3X to accelerate the discovery of novel drugs. We constructed a tetracistronic adenoviral vector, Ad-MBRG for targeted delivery of tumour suppressor genes MOAP-1, Bax, and RASSF1A, known to be epigenetically silenced in many cancers and contribute to apoptotic pathway dysfunction. This approach aims to restore apoptotic signaling and enhance cancer cell sensitivity to treatment. The study outlines a multi-step methodology for establishing the Ad-MBRG-mediated sensitized cell model, including amplification and quantification of Ad-MBRG particles, optimization of infection efficiency in the MCF7-CR cancer cell line, and evaluation of their sensitivity compared to non-infected controls. Furthermore, we explored the potential synergistic effects between Ad-MBRG infection and anti-cancer compounds derived from natural products. This model holds promise for screening anti-cancer compounds, particularly those from natural sources, and evaluating their potential to overcome chemoresistance. This paves the way for further exploration of adenovirus-mediated gene therapy as a platform for novel drug discovery and improved cancer treatment strategies.

Published: November 2024

Pay administration is one of the most important functions in the organisational administration domain. Contemporary research shows that the capability of an organisation’s administrator to share the information about pay administration, encourage employees’ engagement in pay administration, and enforce good performance evaluation may have a positive and significant influence on employees’ commitment toward the organisation. However, there is a limited explanation about the importance of pay administration as an important factor in the organisational pay administration domain. This study is performed to analyse the importance and performance of each element in pay administration towards employee commitment. Main data are collected from 400 self-report questionnaires filled by the employees of Pos Malaysia Berhad in Klang Valley. The results of Partial Least Square - Structural Equation Modeling (PLS-SEM) stipulate that pay administration is positively and significantly interrelated with employees’ commitment. Therefore, the results show that the ability of an organisation’s pay administrator to successfully implement effective information sharing, encourage employee engagement, and practice good performance evaluation in administering pay systems may enhance employees’ commitment to the organisation.

Rose Aromatherapy Mask and Hedonic Test
Authors: Sunandar Kuslan , Roseno M.H , Yulianingtyas
Published: November 2024

Rose aroma therapy is an aromatherapy that contains linalool and geraniol which have soothing properties and provide a relaxing effect on the central nervous system by stimulating the olfactory nerve. The mechanism of action of rose aromatherapy in the human body takes place through two physiological systems, namely the body's circulation and the olfactory system. When the aroma therapy of rose essential oils is inhaled, volatile molecules will carry the aromatic elements contained in it such as geraniol and linalool to the top of the nose where cilia arise from the receptor cells. When molecules attach to cilia, electrochemical messages are transmitted through the olfactory channels into the limbic system. This will stimulate memory and emotional response. The hypothalamus, which acts as a regulator, gives rise to messages that must be conveyed to the brain. The messages received are then converted into actions in the form of electrochemical compounds that cause feelings of calm and relaxation and can facilitate blood flow. The purpose of this study was to measure the effectiveness of rose aromatherapy masks on reducing blood pressure and measure preferences for rose aromatherapy masks based on the aroma and comfort. During the pandemic, the use of masks is a behavior that must be habituated so that it becomes a daily behavior. The second year's research report is a preference test or hedonism test. The content of aromatherapy oils applied to masks is made in four levels, namely 100%, 75%, 50% and 25%. The method of applying aromatherapy oil to masks uses evaporation at room temperature with different durations, namely; 6 hours, 12 hours, 18 hours and 24 hours. The results of the test of liking and comfort in wearing aroma therapy masks (hedonic) according to respondents (100%) felt comfortable with a level of 50% with an application time of 6 hours.

Authors:   Russian University of Transport, Ivanchenko I.I.
Published: November 2024

A method for calculating plates under the action of force and inertial loads during their movement with variable acceleration is proposed. The problem of the interaction of an aircraft load, at the moment of its movement in braking mode when using an aerial finisher, with a coating in the form of a rectangular plate of elongated dimensions on an elastic base is considered. Nonlinear contacts of the chassis wheels are taken into account when using piecewise linear characteristics of contact stiffness. The vertical dynamics of the spatial model of the aircraft during the run is modeled by a system of rigid bodies with elastic-viscous bonds. To construct the methodology, the step method proposed earlier by the author of the article is used to solve problems of unsteady dynamics of structures and the method of calculating structures for the action of mobile force and inertial loads (the method of nodal accelerations).

The paper considers the efficiency of destruction of artificial quartz crystals synthesized by hydrothermal method. The data on specific energy consumption for destruction by means of electric pulse and electrohydraulic impacts are given. It is shown that when quartz material fractured to the size of less than 1 mm by electric pulse impact more than 60% of the product by mass corresponds to the useful fraction of less than 0.5 mm. At the same time reduction of the applied voltage leads to an increase in the average product coarseness. In experiments on further additional fragmenting of material larger than 0.5 mm by electrohydraulic impact it was revealed that the efficiency of quartz destruction by this method depends, to a greater extent, not on the pulse energy, but on the rate of energy release, and to increase the productivity of the process it is necessary to use discharges with high brisance.

Role of Islamic Thought and Culture in the Artifical Intelligence World
Authors: Ibrahim Shogar
Published: November 2024

Regardless of the negative picture casted by the hostile media about Islam, the global community is increasingly showing interest in understanding the Islamic thought and culture for various purposes, including political and economic influence. Thus, Muslim intellectuals need to be aware of this fact and get ready for its implications at both local and global levels. Study of other cultures, i.e., religions, languages and lifestyles of other nations, in the globalizing world, which characterized by free movement of ideas and artificial intelligence (AI) technologies, is important as a basic means for effective communication, mutual understanding and cooperation between nations. The Holy Qur`an shifts attention of the global community to the importance of mutual understanding between nations, saying: “O people! We have created you all out of a male and a female, and have made you into nations and tribes so that you might come to know each another’’ (49:13)[1]. The progress in new technologies, especially in (AI) technology, have significantly influenced the Islamic culture over the last few decades. This paper aims to investigate role and the future directions of Islamic thought and culture, as impacted by the new technologies, especially in its methods of teaching and learning. Critical examination is necessary in adopting the new technologies to ensure that scientific advancements are align with the principles and objectives of Islamic thought. The method adopted in this paper is theoretical and analytical in nature. It is expected that the outcomes of the paper will provide clear guidelines for Islamic thought to harness the potential prospects of new technologies and overcome its challenges in Muslim societies.
