The main causes of anaesthesia-related mortality were problems wi

The main causes of anaesthesia-related mortality were problems with airway management and cardiovascular events related to anaesthesia and drug administration [8].Important signs of inadequate patient GA (Figure 1), signs selleck Bosutinib which develop in response to stress or painful stimuli, are movement, increased breathing or heart rate and increased blood pressure [9]. These warning signs are often attenuated since many surgical procedures require administration of a muscle relaxant or the patient receives medication that affects the heart rate and blood pressure [9]. Avoidance of muscle relaxants is no guarantee of avoiding awareness. Studies have reported patients with awareness under non-relaxant anaesthesia [3�C5]. Fortunately, such awareness is very rare and very rarely reported as unpleasant [3].

Figure 1.The relationship between surgical stimuli, general anaesthetics and awareness.It is generally believed that awareness will not occur if GA is maintained with a volatile agent delivered to the patient��s blood at a concentration of at least 0.5 minimum alveolar concentration (MAC) [9]. However, for some Inhibitors,Modulators,Libraries patients, the use of total intravenous anaesthesia techniques is more appropriate [3,10�C13]. Individual variations in patient drug requirements will also lead to occasional over dosage or under dosage with both volatile-based and intravenous-based techniques [9,11]. Failure to adjust the anaesthetic requirements to individual variations in patient drug requirements and to the intensity of pain stimulation during a specific surgery procedure will also lead to over dosage or under dosage with both volatile-based and intravenous-based techniques [9,11].

1.2. Monitoring anaesthetic delivery is not the same as monitoring anaesthetic effectThe potencies of general anaesthetics Inhibitors,Modulators,Libraries Inhibitors,Modulators,Libraries range over at least five orders of magnitude [14]. However, for any given anaesthetic, the concentration at which consciousness is lost is well defined. For intravenous or volatile anaesthetics, the transition from the conscious Inhibitors,Modulators,Libraries to the unconscious state occurs abruptly over a change in concentration of only a factor of less than 1.6 [14]. The physiological mechanism for this abrupt switch between consciousness and unconsciousness was explained by the intrinsic bi-stability of thalamocortical neurons coupled with the reciprocal inhibitory connections between hypothalamic sleep-promoting centres and the arousal nuclei in the midbrain and the brainstem, which would tend to favour rapid transitions between high and low states of ascending arousal [14].

Administration GSK-3 of at least 0.5 MAC of a volatile anaesthetic agent should prevent awareness [15] and most anaesthetists employ this approach to prevent awareness in their daily practice [9]. Similar results can be obtained with total intravenous infusion devices that incorporate predicted plasma and effect site table 5 concentrations [16].

The Hysteresis and eddy losses are present in the

The Hysteresis and eddy losses are present in the Seliciclib Cdc2 giant magnetostrictive materials [12�C14] and they are considered in the sensor model.Figure Inhibitors,Modulators,Libraries 1.Biasing a Terfenol-D (a) with the DC biasing; (b) without the DC biasing.Figure 2.(a) Sensor placement in the overhead transmission line. (b) Sensor detail design including Terfenol-D, fiber optic cable, and strain sensor.3.?FBG SensorsFBG sensors can work as arrays for real time measurement of temperature, strain, and pressure in the systems. Optical fiber sensors have numerous advantages such as electrically passive operation, EMI immunity, high sensitivity, and multiplexing capabilities which make them a perfect candidate to use in power systems.

FBG sensors are commonly used Inhibitors,Modulators,Libraries for strain and temperature measurement and they can measure strain up to ��5,000 �̦� and temperature ranges from ?40 ��C to +120 ��C Strain causes change in the grating pitch and the fiber index of the sensor. The sensed strain in FBG sensor is then coded directly Inhibitors,Modulators,Libraries into the wavelength and can be detected as wavelength shift. FBGs reflect a narrowband of light and transmit all other wavelengths. In other words, FBG is an optical fiber that works as a filter for a particular wavelength. The principal of a FBG based sensor is to detect the reflected Bragg wavelength shift due to changes in temperature, strain, or pressure. The Bragg wavelength is defined as follows [15].��B=2neff��(1)where, �� is the grating pitch and neff is the effective index of the fiber core. Bandwidth of the Bragg reflected signal depends mainly on grating length and it is typically around 0.

05 to 3 nm.OCT used in this experiment consists of FBG strain and temperature sensors and a giant magnetostrictive material bounded together with epoxy. As described earlier, biasing point of the sensor can be adjusted by mechanical prestress on magnetostrictive material and the amp-turn of the DC biasing solenoid. Inhibitors,Modulators,Libraries One of the main advantages of the OCT sensor, which can substantially reduce AV-951 the cost of implementing power system, is that the OCT sensor does not require any CTs and PTs for biasing to detect the fault in the system. Terfenol-D (TbxDy1?xFey) was chosen as the magnetostrictive material due to its fast response (<0.1 ms) [16,17] and capability of producing a substantial amount of strain in the magnetic field.

A broad band source was used to illuminate the FBG through a selleck chem inhibitor single mode fiber optic and optical coupler. The principle of FBG is well known [15] and will not be explained in detail here. A small change in strain and temperature both cause wavelength shift on the reflected FBG wavelength by following equations:���˦�0=k?+��nTemp��T.(2)��nTemp=��nn��T(3)where, ���� is the wavelength shift, ��0 is base wavelength in nominal temperature and strain, ��T is the temperature change, k is the gage factor which is normally 0.

Thus, researchers or engineers could potentially use FBG and LPFG

Thus, researchers or engineers could potentially use FBG and LPFG sensors with the same measurement apparatus, such as the ASE light source and these optical spectrum analyzer (OSA), to monitor changes of strain, temperature, and liquid-level over time.2.?Fiber Grating SensorsWe used fiber grating sensors, FBG and LPFG sensors, as FOSs for the NDE of smart infrastructure materials. Figure 1(a) shows a schematic of the experimental setup of a reference dual-wavelength grating FBG sensing system. The FBG sensors were used to examine the temperature and strain responses of infrastructure materials. The fiber sensor was consisted of a bare grating pair (��1 and ��2) and a packaged reference grating (��3). The bare grating pair was constructed by fusion splicing two fiber Bragg gratings in cascade with different Bragg wavelengths.

The three Inhibitors,Modulators,Libraries fiber Bragg gratings at wavelengths of ��1, ��2, ��3 were interrogated using a broadband ASE source and an OSA. A fiber Inhibitors,Modulators,Libraries coupler was used for coupling the reflected light signals of the sensor to the Inhibitors,Modulators,Libraries OSA. The reference grating was used to measure only the temperature effect. The change in the Bragg center wavelengths ����i of the two gratings from the changes in temperature (��Ti) and strain (����i) could be obtained using Equation (1).Figure 1.Schematic of experimental setup of (a) a reference dual-wavelength grating FBG sensing system for temperature and strain measurements; (b) an LPFG sensing system either for temperature or liquid-level measurements.Figure 1(b) displays the schematic of experimental setup of an LPFG sensing system.

The LPFG sensors were used to examine Inhibitors,Modulators,Libraries the temperature and liquid-level responses of infrastructure materials. The LPFG sensors were used as either a temperature sensor (wavelength of ��4) or a liquid-level sensor with five LPFGs in cascade with different wavelengths (wavelengths of ��5, ��6, ��7, ��8, and ��9, about 20-nm wavelength interval).2.1. Fiber Bragg Grating SensorsFor discriminating the strain and temperature effects, the use of reference grating [7], the use of dual wavelength gratings [8], and the use of two sensors associated with different strain and temperature responses were reported [9�C14]. Another approach is to use the dual wavelength technique involving writing two superimposed Bragg gratings [8], in which the responses to temperature (��1T,��2T) and strain (��1��,��2��) at the same location on the structure are different.

The change in the Bragg center wavelengths GSK-3 ����i of the two gratings from the changes in temperature (��Ti) and strain (����i) is given by the following matrix expression:����i=��i?��?i+��iT��Ti i=1,2(1)where ��i�� = ?��/?��i is the strain coefficient of material related to the Poisson ratio, photoelastic constant and effective refractive index, and ��iT = ?��/?Ti is the temperature new product coefficient related to the thermal expansion and thermo-optic coefficients.

Sensor technology is continuously improving as the devices become

Sensor technology is continuously improving as the devices become smaller, cheaper, more intelligent, and more power efficient. In consequence, more and more application fields are making use of these technologies. Examples are disaster management, environmental thoroughly monitoring, precision agriculture, Inhibitors,Modulators,Libraries early warning systems, home as well as public security, or human health [4�C6]. The kinds of sensor resources utilized in these applications may be stationary or in motion and could gather data in an in-situ or remote manner. Due to the large variety of sensor protocols and sensor interfaces, most applications are Inhibitors,Modulators,Libraries still integrating sensor resources through proprietary mechanisms, instead of building upon a well-defined and established integration layer.

This manual bridging between sensor resources and applications leads Inhibitors,Modulators,Libraries to extensive adaption effort, and is a key cost factor in large-scale deployment scenarios [7].This issue has been the driving force for the Open Geospatial Consortium (OGC) to start the Sensor Web Enablement (SWE) initiative ( back in 2003. Within the SWE working group a suite of standards has been developed which can be used as building blocks for a Sensor Web. SWE defines the term Sensor Web as ��Web accessible sensor networks and archived sensor data that can be discovered and accessed using standard protocols and application programming interfaces�� [8]. First described by Delin et al. in 1999 [9], a Sensor Web was considered as an autonomously organized wireless sensor network which can be deployed to monitor environments.

As a smart macro instrument for coordinated sensing [10], Delin��s Sensor Web concept consists of sensor nodes Inhibitors,Modulators,Libraries which not only collect data, but also share their GSK-3 data and adjust their behaviour based on that data. Thereby, the term ��Web�� within Delin��s ��Sensor Web�� relates to the intelligent coordination of the network rather than the World Wide Web (WWW) [11]. Later, the meaning of ��Sensor Web�� changed and it was more and more seen as an additional layer integrating sensor networks with the WWW and applications [12�C14]. Today, the notion of ��Sensor Web�� has been largely influenced by the developments of the SWE initiative. It is defined as an infrastructure which enables an interoperable usage of sensor resources by enabling their discovery, access, tasking, as well as eventing and alerting within the Sensor Web in a standardized way.

Thus, the Sensor Web is to sensor resources what the WWW is to general information sources��an infrastructure allowing users to easily share their sensor resources in a well-defined way [15]. It hides the underlying layers, the network communication details, and heterogeneous sensor hardware, from the applications built on top of it.To achieve selleck chemicals Tofacitinib this, SWE incorporates models for describing sensor resources and sensor observations.


Paclitaxel After hydrothermal reaction, the product was washed with distilled water 4 times and ethanol 1 time by centrifuge and dried at 70 ��C for 24 h. The pure and additive-loaded In2O3 hollow spheres could be prepared by the heat treatment of the above products at 500 ��C for 2 h. For simplicity, hereinafter, the pure, Cu, Nb, Ni, Pd, Sb-loaded In2O3 hollow spheres after heat treatment will be referred as In2O3, Cu-In2O3, Nb-In2O3, Pd-In2O3, Ni-In2O3, and Sb-In2O3 specimens, respectively. The morphologies of the hollow spheres were analyzed by field-emission scanning electron microscopy (FE-SEM, S-4800, Hitachi Co. Ltd.).For the gas sensing measurement, 0.1 g of each prepared hollow sphere was dispersed in 10 mL of D.I. water and these solutions were deposited on the sensor substrate by using the drop-coating technique.
An alumina substrate (1.5 �� 1.5 mm2) with two Au electrodes on its top surface and a micro-heater on its bottom surface was used. The temperature of the sensors was controlled by modulating the power of the microheater underneath the substrate. The sensor temperature was measured to be 371 and 440 ��C at the heater powers of 400 and 500 mW, respectively, by an IR temperature sensor (Rayomatic 14814-2, Euroton IRtec Co.). The uncertainty of sensor temperature was ��5 ��C. The sensor was positioned in a specially designed quartz tube chamber and dry synthetic air and mixing gas were flowed into this chamber. The gas response (S = Ra/Rg, Ra: resistance in air, Rg: resistance in gas) to 500 ppm CH4, 100 ppm NH3, H2, CO, and 5 ppm of H2S were measured using a multimeter (Keithley K2000) which connected with a computer.
3.?Results and DiscussionAll the as-prepared specimens after hydrothermal reaction were spheres with a size of 5�C7 ��m (Figure 1). The surface morphology, the presence of nano-size particles, and the connectivity between carbon spheres were slightly different Cilengitide for each specimen according to the doping of additives. After heat treatment of the precursor spheres at 500 ��C for 2 h, the as-prepared precursor spheres with clean surfaces (Figure 1) were converted into spheres with rough surfaces consisting of primary nanoparticles (Figure 2).Figure 1.SEM images of as-prepared carbon spheres coated with In- and additive-precursors: In-PR (precursor spheres selleck chemical to be converted into In2O3 hollow spheres); M-In-PR (M = Sb, Cu, Nb, Pd, and Ni; precursor spheres to be converted into M-In2O3 hollow spheres).
…Figure 2.SEM images of In2O3, Sb-In2O3, Cu-In2O3, Nb-In2O3, Pd-In2O3 and Ni-In2O3 spheres after heat treatment at 500 ��C for 2 h.The average diameters of ~100 In2O3, Sb-In2O3, Cu-In2O3, Nb-In2O3, Pd-In2O3 and Ni-In2O3 spheres were 2.3 �� 0.5 ��m, 2.4 �� 0.7 ��m, 2.2 �� 0.4 ��m, 2.3 �� 0.6 ��m, 2.3 �� 0.5 ��m, and 2.2 �� 0.5 ��m, respectively.

This approach will strictly distinguish between impersonalized kn

This approach will strictly distinguish between impersonalized knowledge during context generation and personalized knowledge despite for anomalous behavior discovery.Changes in behavior concerning ADLs can be seen as an early indicator of autonomy loss [6]. One of the earliest assessments of human behavior related to the ability to live independently was conducted by Katz et al. [7]. A significant drawback of questionnaires such as those used in that study is that elderly people tend to lie about their difficulties (due either to fear of the consequences or to shame).Later, Lawton [8] constructed a hierarchical taxonomy of behavioral competence. He presents five major categories, from simple to complex: health, functional health, cognition, time use and social behavior.
The hierarchy demonstrates that the complex tasks rely heavily on the simple ones. He states that residential behavior is closely related to cognitive competence.Telemonitoring products concentrate on well-being at the health [8] level (e.g., 24-hour ECG monitoring). We tackle the automatic detection of behavioral competence at the, functional health level. Basically, we focus on the physical (sometimes called basic) and instrumental aspects of ADLs. So far, we have defined the following ADLs: going to the toilet, transferring, waking/sleeping, dressing, eating, washing, bathing, combing and napping.To a certain degree, people reveal their current context (activity, location, identity and time) [9] by interacting with their environment (e.g., by opening the doors of a cupboard).
Assuming additional semantic information is provided, it is possible to draw inferences about any activity currently being performed simply by augmenting their surroundings with the appropriate sensors.When considering an individual’s daily habits, some repetitive patterns can easily be observed, starting with the person’s wake-up routine [10]. After collecting enough context information about a specific person to create a temporal relationship model of his/her daily activities, we can assess to what extent the current day’s pattern of activities matches those of previously observed days.The system described in this article is intended as an aid to the caregiver. Therefore, one highly influential concern in its design is the awareness that in practice the caregiver will have very limited time to interact with an assessment tool.
To this end, we have created a novel human autonomy assessment system (HAAS) Brefeldin_A at different levels: during the specification phase, a clear and easy-to-understand language had to be chosen so the developer can profit from the domain knowledge of the caregiver. When it comes to visualization, we had to find a highly condensed behavioral information representation sellectchem of the client’s daily living skills.We use the term client to refer to the person the caregiver looks after.

The accuracy of these measurement methods is much higher than tha

The accuracy of these measurement methods is much higher than that of the previously mentioned bulk fluid measurement methods. However, as the number of cells that are available for measurement is quite small, these methods are not suitable for clinical diagnoses.Microchannels and microsensors have recently come to be considered as powerful tools in clinical diagnoses. The use of microsensors offers not only the advantages mentioned earlier, but also an effective solution to problems encountered in the measurement of RBC deformability with a high accuracy. Tracey et al. [16] fabricated a microchip with several embedded microchannels having a width of 4 ��m and visually measured the deformation rate of cells that passed through the microchannels. Korin et al.
[17] proposed an interesting method to visualize the behavior of RBCs in a microchannel; the cell deformation is measured by analyzing their images as they are stretched by high shear flows. However, this method requires high-resolution image-recording equipment that is bulky and expensive.The microsensor proposed in this study measures the electric resistance of RBCs as they pass between its electrodes. Figure 1 shows a schematic of the basic elements of the proposed sensor. As shown in Figure 1(a), micro-membrane-type electrodes are attached to the bottom wall of the microchannel. An RBC is suspended in the flow and is controlled such that it passes between the electrodes. An equivalent circuit that represents the electric characteristics of the region between the electrodes is shown in Figure 1(b).
The circuit consists of the cell, a solution, and an electric double layer formed on the surface of the electrodes. The cell is composed of the cytoplasm and cytomembrane. The resistance of the cytomembrane is much larger than that of the solution and is less than 1 �� 10�C6 S/m. This value is less than that of the cytoplasm and normal saline solution; thus, the cytomembrane acts as an insulating material. In this case, Drug_discovery the resistance obtained from the impedance measured by the electrodes will be influenced mainly by two factors: that are, the resistance of the membrane and how the current flux in the electric field is interruption by the cell. This means that the measured resistance will reflect the size, height position, and shape of the cell. In addition to this, when the RBC passes the electrodes, the resistance will increase as it approaches the center of the electrodes and then decreases as it moves away; namely, the resistance will show a time-series distribution similar to the one shown by the graph in Figure 1(a). The previously mentioned parameters are considered to not only influence the resistance itself but also this time-series distribution of the resistance.Figure 1.

Recognizing different kinds of vegetables and fruits is a difficult task in supermarkets, since the cashier must point table 5 out the categories of a particular fruit to determine its price. The use of barcodes has mostly ended this problem for packaged products but given that most consumers want to pick their products, they cannot be prepackaged, and thus must be weighed. A solution is issuing codes for every fruit, but the memorization is problematic leading to pricing errors. Another solution is to issue the cashier an inventory with pictures and codes, however, flipping over the booklet is time consuming [1].
Some alternatives were proposed to address the problem. VeggieVision was the first supermarket produce recognition system consisting of an integrated scale and image system with a user-friendly interface [2]. Hong et al. [3] employed morphological examination to separate walnuts and hazelnuts into three groups. Baltazar et al. [4] first applied data fusion to nondestructive image of fresh intact tomatoes, followed by a three-class Bayesian classifier. Pennington et al. [5] used a clustering algorithm for classification of fruits and vegetables. Pholpho et al. [6] used visible spectroscopy for classification of non-bruised and bruised longan fruits, and combined this with principal component analysis (PCA), Partial Least Square Discriminant Analysis (PLS-DA) and Soft Independent Modeling of Class Analogy (SIMCA) to develop classification models.
The aforementioned techniques may have one or several of the following shortcomings: (1) they need extra sensors such as a gas sensor, invisible light sensor, and weight sensor. (2) The classifier is not suitable to all fruits, viz., it can only recognize the varieties of the same category. (3) The recognition systems are not robust GSK-3 because different fruit images may have similar or identical color and shape features [7].Support Vector Machines (SVMs) are state-of-the-art classification methods based on machine learning theory [8]. Compared with other methods such as artificial neural networks, decision trees, and Bayesian networks, SVMs have significant advantages because of their high accuracy, elegant mathematical tractability, and direct geometric interpretation. Besides, they do not need a large number of training samples to avoid overfitting [9].In this paper, we chose an image recognition method which only needs a digital camera.

FTSEC transformation that incorporate common somatic genetic alte

FTSEC transformation that incorporate common somatic genetic alterations characteristic of HGSOC or even recently discovered Erlotinib susceptibility alleles that confer low risk of EOC in the general population will be vital tools in answering some of the key questions regarding EOC initiation and development. Conclusion In conclusion we have developed a novel 3D in vitro culture model of fallopian tube secretory cells that rep resent a precursor tissue of high grade serous ovarian cancer. The greatest potential clinical use for these models is likely to come from molecular and phenotypic studies of the initiation and early stage development of ovarian cancer leading to the discovery of novel bio markers for early stage disease detection.

These models may also have applications beyond the study of ovarian carcinogenesis, for example for studying the interactions between the fallopian tube epithelium and oocytes or zy gotes. Co culture of fallopian tube epithelial cells has been shown to promote the in vitro development of em bryos. In future, novel 3D co culture methodologies, in which glycoprotein secretion is enhanced, may improve in vitro embryogenesis. Models of benign fallopian tube diseases that are commonly associated with female infer tility, such as salpingitis and pelvic inflammatory disease, are also few in number, but the models we describe here could be used to mimic such conditions in vitro and help to improve their diagnosis and treatment.

Ultim ately, it is hoped that these models will lead to much needed insights into the biology and pathogenesis of fal lopian secretory epithelial cells and that this knowledge with be invaluable in increasing our ability to diagnose and treat benign and malignant disease arising in the fal lopian tubes. Methods Tissue collection and cell culture Patients scheduled to undergo surgical procedures for benign gynecological conditions or total abdominal hysterectomies for endomet rial cancer provided informed written consent, prior to surgery, agreeing to participate in the study. This study was performed with permission of the UCL Institutional Ethics Committee. Fallopian tubes were inspected by the operating surgeon and a gynecological pathologist and confirmed to be free of malignancy. The distal ampul lary region of the fallopian tube was isolated and dissected open to reveal the lumen.

Epithelial cells were harvested by gentle brushing with a sterile cytobrush. All FTSEC cell cultures were maintained in MCDB105,Medium 199 supplemented with 15% fetal bovine Cilengitide serum, 10 ng ml epidermal growth factor, 0. 5 mg ml hydrocortisone, 5 mg ml insulin, and 34 mg protein ml bovine pituitary extract, For growth curves 1 �� 105 cells were plated in triplicate. Cultures selleck chemicals were passaged and population dou blings calculated using the following formula, PD log log2. For analysis of cellular karyotype, cells were taken at a low passage and seeded at low density in a 25 cm2 flask. The karyotypes were analysed by a certified clin

ed at lower level by proteasomal deg radation. During hypoxia the degradation of HIF 1 is inhibited, and then HIF 1 heterodimerizes with HIF 1B and translocates to the nucleus. HIF 1 B dimer selleck chem binds to hypoxia response elements and activates target genes transcription, including heme oxygenase 1, erythropoietin, vascular endothelial growth factor, and various glycolytic enzymes that contribute to adaptation to hypoxia and or ischemia. Therefore HIF 1 plays a key role in hypoxic ischemic response. Recent studies indicate that miRNAs play important roles in hypoxia ischemia. MiR 494 has been reported to be significantly increased in ex vivo ischemia reperfusion mouse hearts. Moreover, miR 494 has cardiopro tective effects against ischemia reperfusion induced injury by targeting both proapoptotic proteins and antiapoptotic proteins to active the Akt mitochondrial signaling pathway.

Obviously, HIF 1 plays an important role in hypoxia and or ischemia conditions. Studies have shown that Akt can augment HIF 1 expression by increasing its translation under both normoxic and hypoxic conditions. However, the potential link between miR 494 and HIF 1 is unknown. We hypothesize that miR 494 may have a role in influen cing HIF 1 expression and contribute to the cellular re sponse to hypoxia. Simultaneously, almost all previous studies about miR 494 were implemented in tumour cells or myocardial cell. The role of miR 494 in liver cell was unclear. Therefore, the present study was undertaken to investigate the influence of miR 494 on HIF 1 expression and its relative mechanism in human hepatic cell line L02.

We also investigated the function of miR 494 in response to hypoxia induced apoptosis. Our results showed that miR 494 were upregulated up to peak after 4 h of hypoxia in the L02 human hepatic cell line. Furthermore, we found that overexpression of miR 494 increased the of expres sion HIF 1 through activating the PI3K Akt signaling pathway and protected against hypoxia induced apoptosis in the immortalized hepatocyte cell line L02. Methods Cell culture The L02 human hepatic cell line purchased from China Center for Type Culture Collection was cultured in RPMI 1640 medium supplemented with 10% fetal bovine serum. Cells were grown under normoxic or hypoxic conditions at 37 C 5% CO2. Specially, medium was replaced with Dulbeccos modified Eagles medium without serum and glucose during hypoxia.

To block PI3K Akt signaling pathway, LY294002 was added to the culture medium. MiRNA and cell transfection MiR 494 mimic and the negative control were obtained from RiboBio. The miR 494 overexpression study was performed using miR 494 mimic and its negative control. Cells were cultured to 30 50% confluence, and transfected with Batimastat miR 494 mimic and negative control using Lipofectamine 2000 in serum free Opti MEM medium according to the manufacturers instruction. Cells were cultured in fresh Volasertib molecular weight medium containing 10% FBS after transfection. Transfected cells were cultured for 48 hou
