In recent decades, there has been significant growth in interconnected communication devices, with the Internet of Things (IoT) being one of the most intensively developed wireless communication appliances. This concept can be implemented in several areas, including smart cities, transportation, telemedicine, agriculture, and wearable applications. However, this increase in connectivity demand can lead to spectrum shortages in the future. In addition, in the development of future green communications, it is crucial to incorporate self-powered systems using energy harvesting technologies. In this review, it is shown that the integration of cognitive radio and radio frequency energy harvesting into IoT development can address the spectrum shortages and energy issues mentioned earlier. The findings indicate that the operating model works based on the slotted approach and state consideration, and the system’s performance metric can be optimised by adjusting parameters such as harvesting time, sensing time, transmit time, transmission power, interference level, and others. This review provides a comparative summary of several focus domains, such as RF harvesting, spectrum sensing and utilisation, operating models, and some open research issues for further work.

Brachytherapy is an integral part of the treatment of cervical cancer. In brachytherapy, the dose delivered to the tissue is determined primarily by the inverse square law thus the dose decreases rapidly as the distance from the source increases. Therefore, an important role in dose distribution is the geometry of the applicator. A patient’s anatomy as well as the fact that the patient may have been operated on must also be taken into account when selecting the applicator. The aim of this study was to assess the influence of the type of cervical cancer brachytherapy applicators (tandem and ovoids or vaginal cylinder) on the dose delivered to adjacent organs, urinary bladder, and rectum. The treatment plans of 10 patients with cervical cancer treated by intracavitary brachytherapy were reviewed, and dose distribution data was collected. Prescribed doses were 7 Gy (or 8 Gy)/fractions, and the number of fractions was from 3 to 5, thus cumulative target EQD2 was between 85-90 Gy. Deliveries of doses to the rectum and bladder were controlled within the tolerance ranges. It was found that the selection of the applicator and the doses administered to the bladder and rectum were correlated. Tandem and ovoid applicators produced lower doses in the bladder and rectum by approximately 20% than the vaginal cylinder. The results of this analysis may potentially enable the optimization of dose distribution for organs at risk in each individual clinical situation.

This study aimed to investigate the presence and activity concentrations of natural radionuclides and cesium in soil samples collected from the Zlatibor region. A total of ten soil samples were collected from various locations across the Zlatibor area. The analysis was performed using gamma spectrometry to measure the activity concentrations of 226Ra, 232Th, 40K, and 137Cs. Additionally, 137Cs was found in big amounts in some of the samples, indicating its dispersion in the environment. The activity concentrations of the detected radionuclides were calculated, and their potential radiological implications were assessed. The obtained data from this study contributes to the baseline information on the natural radioactivity levels in the Zlatibor region, which is essential for environmental monitoring and radiation protection purposes. Furthermore, the presence of 137Cs highlights the importance of continued monitoring to assess potential radiological risks to the local population and environment.

Agriculture has managed to produce enough food for the accelerated population growth, which has led to environmental transformation and increasingly intensive exploitation of both renewable and non-renewable natural resources. The use of synthetic plant protection agents and fertilizers can lead to negative consequences in food production. Identification of agricultural food production systems is gaining importance in order to protect human health and the environment. Interest in the cultivation of certain plant species with an innovative approach to cultivation and technology has grown significantly. Organic and integrated agriculture implies the use of natural products while limiting or completely eliminating the use of synthetic resources. Knowledge of the mineral composition in tomato samples can be used as a potent tool in the identification of chemical markers as potential indicators of the farming system. The goal of the research is to determine the impact of different production systems on the content of macroelements in the fruits of different types of tomatoes.

Background. Prostate and rectal carcinomas, although among the most common malignancies in males, rarely exhibit synchronous diagnosis and treatment of both malignancies. This paper presents a case of a patient with synchronous prostate and rectal carcinoma and an artificial right hip, which complicates the creation of a radiotherapy plan. Case Report. A 76-year-old male was diagnosed with synchronous mucinous infiltrating adenocarcinoma of the rectum (T3N0M0) and adenocarcinoma of the prostate (T3aN0M0), confirmed by immunohistochemistry. He had a history of testicular carcinoma previously treated with orchiectomy, chemotherapy, and radiotherapy. The treatment approach involved neoadjuvant chemotherapy with 5-fluorouracil and leucovorin, following the protocol for rectal carcinoma, and concurrent radiotherapy for both rectal and prostate carcinoma. The presence of an artificial metal right hip prosthesis made the creation of the radiotherapy plan more challenging. The plan was developed by defining four target volumes and delineating artifacts in the soft tissue and bony structures. It was designed to deliver the prescribed dose using 6 MV photon energy during 25 radiotherapy sessions, applying a simultaneous integrated boost. The best dose delivery was achieved with the VMAT plan, and the analysis of dose-volume histograms (DVH) indicated satisfactory contributions to organs at risk. Conclusion. Individualized approaches in treating patients are particularly important in cases of synchronous tumors. As oncology patients tend to have longer overall survival, special attention must be given to the patient’s quality of life, necessitating organ sparing during radiotherapy treatment. The complexity of treatment planning due to the presence of comorbidities and metal implants is overcome through excellent collaboration between radiation oncologists and medical physicists.

Carbonic anhydrases (CA) have been identified in the early ‘50s as potential targets for the treatment of numerous diseases, including cancer, glaucoma, epilepsy, etc. Current inhibitors, i.e., treatment options, offer high efficacy coupled with a high probability of various side-effects. On the other hand, dithiocarbamates and their metal complexes are known for being good CA inhibitors. In this paper, a novel Fe (II) dithiocarbamato complex was investigated for its biological and pharmacological properties using a combination of different in silico methodologies. It was found that this water soluble, almost non-toxic (LD50 values around 4860 mg/kg), druglike compound shows high inhibitory potential towards CA II. However, it also shows slow gastro-intestinal absorption, which means that, if ever used as a pharmacological agent, in its present form cannot be orally administrated. Binding energies with the value of -7.8 kcal mol-1 indicate reversible binding to human serum albumin, which can serve as a delivery system for the investigated compound. Overall, the obtained results indicate a high potential of (NH4)4[Fe(idadtc)2] to be an effective CA II inhibitor..

The success of patch-clamp giga-ohm seal formation on filamentous fungi Phycomyces blakesleeanus protoplasts was investigated to evaluate their usefulness in ion channel studies on filamentous fungi. Protoplasts were obtained by laser-mediated nanosurgery of the cell wall stained with Calcofluor White. To enable a successful seal formation, it is critical to prevent cell wall regeneration. Since wall integrity responses in fungi involve kinase-dependent pathways, we aimed to sufficiently reduce intracellular ATP availability using the respiratory inhibitor azide. The effect of azide on phosphate metabolites of Phycomyces blakesleeanus, as determined by 31P NMR spectroscopy, was a reduction in intracellular ATP accompanied by a decrease in long chain polyphosphates. Subsequently, all seal formation measurements were performed in the presence of azide, and protoplast viability was confirmed by cytoplasmic streaming. The success of seal formation depends on the size of the protoplasts, as larger protoplasts are more prone to successful seal formation. It was also found that the laser power used in nanosurgery could influence the success of seal formation, as higher values were associated with a lower success rate. The protoplasts released by laser nanosurgery produced by our newly developed method are a good model system for patch clamp on filamentous fungal membranes because their plasma membrane can easily form high-quality seals with the patch pipette.

As a continuation of our research in the field of synthesis and characterization of dithiocarbamate (DTC), we are developing mechanochemical protocols for the synthesis of new compounds with potential biological activity. Optimizing the methods of obtaining desired compounds is of special importance for a completely eco-friendly science, and one of the prospective strategies is mechanochemistry, recognized as a green, sustainable synthesis method. Herein we present the mechanochemical reactions of homopiperazine and CS2. The aim was to obtain homopiperazine dithiocarbamate derivative through mechanochemical synthesis. The optimization of the process was carried out through mechanochemical grinding in the planetary ball-mill using zirconium oxide grinding media (jars and balls), under various reaction conditions. The selected reactions were conducted using a one-pot method. Chemical and spectral characterization revealed that the product was obtained in the form of a dimer with a good yield. Water and NaHCO3 were generated as by-products. Homopiperazine-1,4-bis-carbodithioate was synthesized for the first time in a ball-mill under mechanochemical and solvent-free conditions. This protocol is promising and thus constitutes an appealing alternative both in academic research and in practical processes, being simple to perform, cheap, scalable, and occurring under mild conditions.
Cryoablation of the adenohypophysis in the treatment of chronic pain syndrome in patients with stage IV malignant neoplasms
Authors: Tsyhankov O.V. , Chyzh M.O. , Hladkykh F.V.
Published: October 2023

Background. The data of the European Society For Medical Oncology (ESMO) indicate that 64.0% of cancer patients with the fourth stage of cancer have chronic pain syndrome, which is the main factor that significantly affects the quality of life. In 46.0% of patients, it is not possible to obtain a stable analgesic effect with modern methods of analgesia, including interventional methods and pharmacotherapy. Refractory oncological pain stimulates the search for new methods of pain relief.

Purpose – retrospective assessment of the effectiveness of the selective stereo- tactic transnasal transsphenoidal cryoablation of the adenohypophysis in the treatment of chronic pain syndrome in patients with stage IV malignant neoplasms.

Materials and methods. 45 microsurgeries were performed – stereotactic selective transnasal transsphenoidal cryoablation of the adenohypophysis with endoscopy. Over the period from 2014 to 2018, 45 patients with stage IV malignant hormone- dependent neoplasms of various somatic organs and chronic pain syndrome underwent microsurgery.

Results. The analgesic effect appeared 4–6 hours after the microsurgery. In 95.6% of patients, an analgesic effect was achieved to a greater extent (according to the numeric rating scale (NRS) for pain, its intensity decreased from 7–9 points to 1–3 points); in other patients, the analgesic effect was achieved to a lesser extent (according to the NRS, pain intensity decreased from 7–9 points to 3–5 points), regardless of the condition and age of the patient. Accordingly, the dosage was reduced or opioid analgesics were discontinued. Severe complications after the cryoablation of adenohypophysis, such as meningitis, diabetes insipidus, and hypopituitary syndrome were not observed. In the postoperative period, three patients were treated for mild hypopituitary syndrome, and two patients were treated for liquorrhea with conservative therapy for 3–5 days.

Conclusions. Stereotactic selective transnasal transsphenoidal cryoablation of the adenohypophysis is an effective microsurgery in the treatment of chronic pain syndrome in stage IV cancer patients. It improves the patient’s condition and quality of life. The analgesic effect appears in the first hours after surgery. Due to the use of cryoprobes with a diameter of 1.2 mm and 1.8 mm, the surgery is minimally traumatic and can be performed on patients in critical condition.
Oncolytic potential of autonomous parvoviruses
Authors: Buchatskyi L.P.
Published: October 2023

Background. In many countries, more than 40 oncolytic viruses from 10 different families are undergoing clinical trials (phase I, II, III) against various types of cancer; some of them have already been approved for use. The results of the experimental studies that deal with the development of oncolytic drugs based on autonomous parvoviruses deserve special attention.

Purpose. The purpose of the study was to analyze and summarize literature sources that are concerned with the development of oncolytic drugs based on autonomous parvoviruses.

Materials and Methods. Publications were selected using keywords in PubMed (https://pubmed.ncbi.nlm.nih.gov/) and Google Scholar (https://scholar.google.com/) databases published over the period from 2010 to 2023.

Results. Among autonomous parvoviruses, protoparvoviruses are the most promising for the development of anticancer drugs. They detect CPE mainly in tumor cells, CPE is absent or limited in non-transformed human and rodent cell lines. Many of them are capable of actively replicating in cancer cells without destroying normal body cells. They primarily block the pathways of activation of type I interferons. The main non-structural viral protein NS1 plays a significant role in the manifestations of oncolytic activity of protoparvoviruses.

Conclusions. Numerous studies continue to be directed at studying the mechanisms associated with the oncolytic properties of autonomous parvoviruses. The use of recombinant parvoviruses allows their oncolytic potential to be enhanced.

There is a mutual relationship between body mass index (BMI), percentage of fat, and total cholesterol levels in the blood. Maintaining a normal BMI becomes a reference for health maintenance. A higher BMI increases the risk of a higher percentage of fat and cholesterol which contribute to a negative impact on health. This study was conducted to determine whether the BMI, fat levels and total blood cholesterol of sportsmen can be maintained properly. The research involved 323 athletes, ranging from 13 - 46 years with an average of 22 years of age. The participants represented 26 sports fields. The BMI test is done by measuring their weight and height. Fat percentage test was conducted by measuring the total fat of triceps, abdominal, and supra iliac fat, as well as by measuring the width of the upper arm, humeral, and femur. The total cholesterol was determined from the blood sample. All data were analyzed using Excel and SPSS IMB serial 26. Results showed that on average the BMI status was 22.82, meanwhile, the percentage of fat was 18.94 and the total cholesterol was 170.77. There was a high correlation between BMI and the percentage of fat (0.505). However, the correlation between BMI and cholesterol was not significant, and only a low correlation was detected between fat percentage and cholesterol.

The purpose of this study was to test the validity of hamstring muscle strength of handball athletes. A total of 30 handball athletes with categories of 15 male athletes (18.0 ± 5.1 years, weight 62.6 ± 20.7 kg, height 173.6 ± 5.0 cm, BMI 22.1 ± 4.0 kg / m2) and female (18.0 ± 5.1 years, weight 54.6 ± 17.4 kg, height 164.7 ± 6.9 cm, BMI 21.4 ± 2.2 kg/m2). No history of lower extremity injuries participated in a hamstring strength test. Hamstring strength tests are performed isometrically with ISO Prone and ISO 60 tests using nordbord tools and load cells tied using hooks called pabletest. From the test results there is a validity level of 0.000 with reliability of 0.8, so that the data can be said to be valid on both tests, namely ISO Prone and ISO 60. Load cells on pabletes are able to measure hamstring muscle strength in handball athletes. The advantages of load cells on pabletes can be made simply but not everyone can make arrangements so as to output data that can be interpreted.  Subsequent research can be done using different contractions such as eccentrics and increasing the number of research subjects more by developing better software.

The Power of Resistance Training: Evidence-based Recommendations for Middle-aged and Older Women's Health
Authors: Marcos-Pardo Pablo J. , Vaquero-Cristóbal Raquel , Huber Gerhard
Published: October 2023

Women have a longer life expectancy, but also a poorer quality of life due to the combined effects of aging and menopause. Among the most widely used non-pharmacological therapies that slow down the effects of these phenomena is resistance training. The aims of this narrative review were: 1) to analyze the strength in health parameters of middle-aged and older women; and 2) to provide a series of practical recommendations for resistance training for women. It was found that resistance training has been shown to prevent and/or treat chronic diseases, improve muscle strength, increase bone density, and reduce the risk of falls and fractures in older women. To conduct our search, we utilized various databases, including MedLine (Pubmed) and Cochrane (Wiley), searching for MeSH-compliant keywords such as: (strength training OR resistance training) AND (middle-aged women OR older women).

The role of ESL vocabulary plays in language competence and literacy development is increasingly prevalent in language acquisition studies, especially so within the domain of second language acquisition research. In Malaysia, generally, the young learners face difficulties in their learning is due to their scarce vocabulary knowledge. This quasi-experimental study scrutinizes how the employment of images in Malaysian primary school level ESL classrooms via the adapted Picture Word Inductive Model (PWIM) effects on students’ ESL vocabulary breadth development. Both the experimental group (n=35) and control group (n=35) consisted of Malaysian national primary school Year 4 pupils. The vocabulary recall and retention of the two intact groups were collated. The data of the two groups were collected from pre-tests, post-tests, and delayed post-tests. These collected data were statistically analysed and assessed. The analysis shown that the Experimental group demonstrated higher recall and retention implying the efficacy of PWIM in enhancing the ESL vocabulary breadth knowledge recall and retention among Malaysian young learners. This study and its findings are of significance to shed light on the development of the ESL vocabulary research. Besides, there is a dearth of thorough study pertinent to the use of images for language learning, especially for the Malaysian primary level 2.
