    Recently, it has been shown a critical role of Rac1 in the emergence of resistance mechanisms to cancer therapy. This review describes the current knowledge regarding Rac1 pathway deregulation and its association with chemoresistance, radioresistance, resistance to targeted therapies and immune evasion. In the past decade, miRNAs have been extensively attracted the scientist’s attentions as tumor suppressors or oncogenes that have been implicated in tumo... The investigation of the mechanisms behind the high radio-resistance of MSCs is essential for advancing our understanding of the role of MSCs in the reconstitution of the hematopoietic system following BMT and in the promotion of tumor growth and survival, which will allow the development of improved therapies.

Radio Resistance Mechanisms of Cancers: An Overview and Future Perspectives Tai-Sheng Wu, Been-Ren Lin, Hao-Hueng Chang and Cheng-Chi Chang* National Taiwan University, Taipei, Taiwan resistance in ohms. The ac (or RF) resistance is higher also. Ohm's Law tells us that the greater the resistance and current in a con- ductor, the higher the loss, or voltage drop. Power is dissipated in the wire, and dissipa- tion causes heat. A coil with too small a wire size can burn up easily. The coil resistance should always be as low as ... Plant defence mechanisms.

    In light of the few mechanisms of radio-resistance that have been reported, we will mainly discuss chemotherapy resistance. HCC associated with HBV infection is less sensitive to chemotherapy because HBX-encoded proteins can promote the direct or indirect development of liver cancer from hepatitis. The evidence is as follows. 3.2 Mechanisms of cephalosporin resistance. Bacteria use multiple different mechanisms to resist the effects of cephalosporin antibiotics. In the final section of this week, you will look at three examples that illustrate the resistance mechanisms described in Section 2: modifying the target; destroying the antibiotic Cancer resistance to therapy presents an ongoing and unsolved obstacle, which has clear impact on patient's survival. In order to address this problem, novel in vitro models have been established and are currently developed that enable data generation in a more physiological context. For example, extracellular-matrix- (ECM-) based scaffolds lead to the identification of integrins and integrin ...

    2. Rac1 is involved in resistance mechanisms. Since last century, cancer treatment has become increasingly sophisticated having profound effects on disease management and patient survival. However, one of the main problems affecting cancer treatment is the emergence of resistance mechanisms to both, standard therapy and targeted-based therapies. Overcoming this kind of resistance could improve the prognosis of rectal cancer patients. Therefore, it is very critical to understand the potential mechanisms of tumorous radio-resistance, to help us find the targets by which sensitivity of the cancer cells could be recovered. Antibiotic-resistant bacteria. Some bacteria are becoming resistant to antibiotics, making antibiotics ineffective. The overuse of antibiotics is responsible for antibiotic resistance as it has ...

Resistance Mechanisms in Radio-resistant Bacteria, 978-3-659-19406-1, Some bacteria have the survival ability under conditions that are commonly considered as extreme, for instance in environments experiencing high pressure or high salt concentrations, or high doses of irradiation. In our experiments, we were studying a bacterium that live in the saturated concentration of salt called extreme ... The extrinsic factors include the resistance mechanisms resulting from the interactions between CSCs and the microenvironment composed of vessels, fibroblasts, immune cells, extracellular matrix, and diverse soluble factors. Furthermore, we introduce diverse therapeutic agents used in experimental or clinical trials to target CSCs.

    benefits in survival. However, the molecular mechanisms underlying this radio-resistance of cancer cells remain poorly understood. One of the most common signatures of highly malignant tumors is their capacity to metabolize more glucose to lactic acid than normal tis-sues, which confers a selective growth advantage [2]. One fundamental problem of most malignancies, including those of haematological origin, is the development of multiple mechanisms of resistance, which progressively reduce or suppress the therapeutic efficacy of conventional radio-chemotherapy. To be highly successful, a radio-therapeutic dose must be sufficient to destroy radio-resistant tumours without damaging the surrounding healthy tissue ...

    Radioresistance - Wikipedia

    Radioresistance is the level of ionizing radiation that organisms are able to withstand.. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1000 gray (Gy) Radioresistance is surprisingly high in many organisms, in contrast to previously held views. Cluster of differentiation CD133 is a well-characterized CSC marker, and it is involved in tumor cell proliferation, metastasis, tumorigenesis, and recurrence, as well as chemo- and radio-resistance. However, the mechanisms involved in CD133-mediated induction of CSC properties have not yet been elucidated. Resistors Failure Mechanisms and Anomalies The primary failure modes of resistors are open circuits and resistance drift. The relative probability of each depends on the application. For example, a resistor used in an application demanding high precision will naturally be more prone to failure due to Table 1.
