In proton therapy the couches used for patient positioning and alignment can affect the uncertainty in the dose distribution from the applied proton beam. In order to limit the additional uncertainty of the proton range, it is necessary to know the determined water equivalent thickness (WET) of the couch top and carefully reflect it in the calculations of the dosimetry planning system. The method presented in this article is based on the difference in the measured depth of the proton beam detected by the multilayer ionization chamber with the beam passing through the couch top and without passing through it.
A range shifter (proton beam modifier) installed in the nozzle with the known WET for evaluating couch tops before commissioning was used in this research work. A nozzle is a proton beam delivery system consisting of quadrupole magnets, ionization chambers and an X-ray tube. CT scans were also acquired to evaluate the internal homogeneity of the test couch tops.
Several kVue couch inserts Proton one (Qfix Systems, Avondale, PA) were evaluated in this study. The results show that the inserts are largely interchangeable for this type of design and the use of the range shifter during treatment, using gantry angles with the proton beam passing through the couch top, does not affect its WET, adding a deflection of approximately 0.1 mm. It was also determined that the reproducibility of the WET determination method has a deviation less than ±0.03 mm. In conclusion, the described above method of couch top testing before commissioning in proton therapy can also be applied to other patient immobilization systems.

Purpose: To study was to study the effect of GNP nanoparticles on tumor cells of human lung carcinoma A 549 when irradiated with protons.
Materials and methods:
Cell culture: Human lung carcinoma cells A 549.
Gold nanoparticles Au/PEG 6000/W 200/30 nm: A colloidal solution of gold nanoparticles purchased from the firm M 9 Nanomaterials & Technologies was used in the work.
Proton irradiation: The irradiation of cells was carried out on a therapeutic proton beam in the Medical and Technical Complex of the Laboratory of Nuclear Problems Joint Institute for Nuclear Research.
Determination of radiosensitivity of cells: By determining the clonogenic survival of cells.
Determination of the genotoxic activity of nanoparticles under the action of proton irradiation: investigated using a micronucleus test with blocking cytokinesis. The genotoxicity of gold nanoparticles was estimated by the number of micronuclei per 1000 binuclear cells. Micronucleus were counted only in binuclear cells. At least 1000 binuclear cells were calculated for each dose, experiments were carried out in three repeats.
Results: The frequency of micronucleus formation indicates an increase in the genotoxic effect of nanoparticles when irradiated with protons at a dose of 2 Gy. Proton irradiation caused an increase in the frequency of micronucleus formation depending on the concentration of nanoparticles. When irradiated with protons at a dose of 2 Gy in the presence and absence of nanoparticles, the difference in the frequency of micronucleus formation for the concentration of nanoparticles was 2.5 mg/ml – 1.1; for 5 mg/ml and 10 mg/ml – 1.2; for 15 mg/ml – 1.3 and for 30 mg/ml –1.5. Cell survival curves reflect a decrease in their survival rate when metal nanoparticles with high Z are added, which reflects the occurrence of radiosensitization effects. The gain for 10 % and 50 % survival rates is 1.4 and 2.5, respectively.
Conclusions: Under the influence of proton irradiation, the genotoxic activity of gold nanoparticles in human lung carcinoma cells A 549 increases, depending on their concentration. The survival rate of human lung carcinoma A 549 cells irradiated with protons in the presence of gold nanoparticles decreases.

The number of patients diagnosed with cervical cancer continues to increase all over the world. Despite the intensive development of diagnostic and therapy methods, the phenomenon of relapses in the absence of a clear explanation for their occurrence, and of metastasis are observed, which complicates treatment and affects the survival of patients. In this regard, there is a need to develop new research methods for a more detailed study of the occurrence and development of the disease at the molecular and cellular levels, as well as the effectiveness of treatment and the causes of relapses.
In this paper, nanoparticles are studied on the surface of red blood cells, which were revealed by the authors using scanning electron microscopy previously, and results of the study of blood samples of patients with cervical cancer using a new sample preparation method and immunofluorescence analysis for their identification are presented on the basis of the assumption that these nanoparticles are viral particles.
With the combination of immunofluorescence and electron microscopy methods, we were able to confirm our hypothesis of the viral nature of nanoparticles attached to the surface of red blood cells of patients diagnosed with cervical cancer. With this approach, it was found that the particles of human papillomavirus 16 and 18 are located on the cytoplasmic membrane of red blood cells. The results of this study indicate that viruses circulate in the patient's blood, and are attached to the surface of red blood cells. This apparently affects the development of cervical cancer, its relapse, and metastasis.

Gas Scrubber merupakan suatu alat yang berfungsi untuk memisahkan kandungan fraksi gas dari liquid dan kotoran di dalam alur proses kompresi gas. Kontrol pressure pada gas scrubber diperlukan agar hal yang tidak diinginkan seperti kelebihan tekanan di dalam vessel gas scrubber tidak terjadi selama proses berlangsung. Metode yang digunakan untuk mengontrol pressure yaitu menggunakan PID control system dimana dalam sistem ini menggunakan tiga parameter utama yang perlu diatur agar didapatkan performansi sistem hasil yang diinginkan. Salah satu metode perancangan PID controller adalah Direct Synthesis. Metode ini hanya memerlukan model plant sebenarnya dan model plant yang diinginkan. Pressure control system di gas scrubber memiliki komponen berupa transmitter, control valve, dan control. Pada pengujian stabilitas sistem pengendalian pressure gas scrubber V-95-202 dengan kontrol aktual menggunakan metode Nyquist Stability dan dapat dinyatakan bahwa sistem stabil. metode direct synthesis memiliki performa respon yang lebih baik dari kontroler aktual, karena memiliki rise time dengan kondisi operasi lebih singkat daripada PID aktual dilapangan yaitu 20.736 detik, settling time yang lebih cepat dengan waktu sebesar 179.484 detik, namun dalam model PID rancangan memiliki sedikit overshoot sebesar 0.5 persen.
