Authors: E. Rajesh Goud , B. Manideep , Paladugu Malyadri , M. Abdul Amjad Khan
Published: October 2024

Carcinoma ex pleomorphic adenoma (CA-ex-PA) represents a highly uncommon form of malignancy within the minor salivary glands of the oral cavity. CA-ex-PA is characterized as a carcinomatous transformation, occurring either as primary lesion or as recurrence of PA. PA can develop into different forms of malignancies like CA-ex-PA, carcinosarcoma or metastasizing PA. This particular type of tumor is predominantly prevalent among women aged between 30 and 60 years. A 55-year-old woman presented with symptoms including swelling on the right side of neck below the jaw, which is suspected to have metastasized from an unknown origin. Intraoperatively submandibular gland excision and right radical neck dissection along with internal jugular vein (IJV) was done to ensure definitive diagnosis. Histopathological results revealed that she was affected with CA-ex-PA stage pT3N2a. After the surgery patient was sent for radiotherapy as a part of her treatment plan and made an uneventful recovery. On the follow-up, the patient has shown no signs of recurrence and has no adverse or anticipated events. CA-ex-PA is a rare, aggressive cancer that can lead to death. Preoperative diagnosis of submandibular gland tumors requires comprehensive clinical history, suspicion of malignancy and radiographic analysis. In order to manage CA-ex-PA and prolong survival rates, prompt diagnosis, a multidisciplinary approach, surgical resection and radiation therapy are essential. Consistent follow-up is also crucial.

Authors: Torres Diego F. M. , Guimarães Fernando S. , Cardoso Alexandre P. , Mello Fernanda C. Q.
Published: October 2024

Background: Few studies have evaluated structured telerehabilitation programs for individuals with post-tuberculosis lung disease (PTLD), resulting in a lack of specific guidelines. This protocol aims to evaluate the physical capacity and quality of life (QoL) of PTLD patients undergoing telerehabilitation.
Methods: This randomized, controlled clinical trial has received internal review board approval and will recruit participants between December 2024 and June 2025, from a referral center in Brazil. Individuals thought to have PTLD, with a mini-mental state examination score >24 and no physical limitations or comorbidities unrelated to pulmonary tuberculosis (TB) will be screened using imaging, total blood count, and biochemical profile. Those with confirmed PTLD will undergo the assessments of: QoL, and physical capacity (spirometry, body composition, calf circumference, six-minute walk test (6MWT), five-times-sit-to-stand test (FTSST), handgrip and isokinetic dynamometry). After that, the participants will be randomly allocated to control or intervention groups. While both groups will receive general guidance on health education and TB prevention, the intervention group will also receive a physiotherapy booklet with instructions for exercises to be performed five times a week for eight weeks. Participants of both groups will be monitored by videoconference, and the same assessment tools will be used to reevaluate QoL and physical capacity outcomes.
Conclusions: The results may demonstrate the benefits of a telerehabilitation program on the physical capacity and QoL of PTLD patients, and may improve accessibility, cost savings, and personalized care through home-based therapy by videoconferencing.

Authors: Naik Minal , Patil Tejal , Gond Bipin
Published: October 2024

Background: Anti-hypertensive drugs are associated with a plethora of adverse reactions which can lead to poor treatment adherence, increased morbidity and mortality rates, and significant economic burden. The blood pressure management program (BPMP) is an Ayurvedic treatment strategy that combines Panchakarma with diet management. Thus, the current study sought to assess the efficacy of the BPMP in essential hypertensive patients to reduce anti-hypertension dependency.
Methods: A retrospective, observational, single-centre study was conducted between December 2018 and September 2023 in Maharashtra, India. Patients aged 30-75 years diagnosed with primary/essential hypertension regardless of gender participated in the BPMP and were included in the study. Follow-up was conducted after 90 days. Day 1 and day 90 data were compared.
Results: A total of 59 patients were assessed. Daytime ambulatory blood pressure monitoring (ABPM) systolic blood pressure decreased (day 1: 123.71±11.83 mmHg and day 90: 123.12±12.36 mmHg), night-time ABPM systolic blood pressure decreased (day 1: 114.76±13.41 mmHg and day 90: 114.31±14.40 mmHg), daytime ABPM diastolic blood pressure decreased (day 1: 77.03±8.28 mmHg and day 90: 76.31±9.45 mmHg, and night-time ABPM diastolic blood pressure decreased (day 1: 69.53±8.32 mmHg and day 90: 68.42±8.85 mmHg). Nocturnal dipping decreased (day 1: 7.08±8.19 and day 90: 6.08±8.99). Dependency on allopathic medication also decreased.
Conclusions: The Ayurveda-based BPMP effectively reduces blood pressure and dependency of allopathic medication. It also improves quality of life of patients diagnosed with primary/essential hypertension.

Authors: Khurana Poornima , Banerjee Rupsa
Published: October 2024

Background: Tobacco use among young people is a public health concern. Perceived stress among young adults as a determinant for tobacco use has not been extensively explored previously in India.
Methods: A cross-sectional study was conducted among young adults aged 18-30 years across India. Data was collected using a self-administered, web-based, online questionnaire, on sociodemographic characteristics, tobacco use and its pattern, and the levels of perceived stress using the Perceived Stress Scale (PSS-10).
Results: The prevalence of tobacco use in our study sample was 25.7% and the mean age at initiation of tobacco use was 20.71 years. Though tobacco use was significantly associated with male gender [aOR=2.26 (1.16-4.38), p=0.01], current alcohol consumption [aOR=13.73 (6.72-28.04), p=0.00] and having known smokers among family and friends [aOR=3.13 (1.39-7.04), p=0.01], there was no association between levels of perceived stress and tobacco use. Cigarettes/beedis were the most commonly used tobacco product, 27.58% of respondents reported using tobacco products daily or for more than half the days of the week and 48.27% of respondents started using tobacco out of curiosity. Seventy percent of users used tobacco during specific events like social gatherings and vacations while 57.47% used tobacco while meeting specific colleagues/ friends.
Conclusions: We found no association between perceived stress and tobacco use. However, current use of alcohol and having knowledge about smokers among family and friends significantly determined tobacco use among our study population. This necessitates more holistic approaches towards behaviour change efforts for tobacco control.

Systemic diseases have a profound influence on oral health and maxillofacial surgical outcomes, presenting challenges that require comprehensive management. Diabetes mellitus is a prominent example, with its impact on periodontal health and healing processes being well-established. Elevated blood glucose levels in diabetic patients impair immune response, reduce collagen synthesis, and delay wound healing, increasing the risk of periodontitis and postoperative complications following surgical interventions such as dental implants. Similarly, cardiovascular diseases exacerbate the inflammatory response linked to periodontal disease, potentially worsening both oral health and systemic conditions, thus complicating the recovery process after maxillofacial surgery. These patients often face heightened risks of infections and slower healing, partly due to the frequent use of anticoagulant medications, which can interfere with surgical procedures. Immunocompromised individuals, such as those with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) or undergoing chemotherapy, also experience significant oral health challenges, including higher susceptibility to oral infections and delayed tissue repair. Reduced immune function and mucosal integrity make it difficult for these patients to recover effectively after maxillofacial surgery, increasing the risk of complications such as infection and wound dehiscence. Moreover, osteoporosis, a systemic condition characterized by reduced bone density, affects the success of dental implants and bone grafting procedures. The decreased bone quality in osteoporotic patients compromises the ability to achieve stable osseointegration, leading to higher implant failure rates and additional surgical challenges. Addressing these complex interactions between systemic health and oral conditions requires an interdisciplinary approach, integrating medical and dental care to enhance treatment outcomes. Proper management of systemic diseases, along with individualized dental and surgical protocols, is essential to improving the prognosis for patients with concurrent systemic and oral health issues.

Sjögren's syndrome (SS) is a chronic autoimmune condition primarily affecting the salivary and lacrimal glands, leading to pronounced dry mouth (xerostomia) and dry eyes. These symptoms create unique challenges for SS patients requiring removable dental prostheses, as the lack of saliva significantly impacts the retention, comfort, and overall effectiveness of these devices. Without adequate saliva, prosthetic retention diminishes, and patients frequently experience issues such as mucosal irritation and increased susceptibility to infections. To address these issues, tailored material choices are critical in designing effective prosthetic solutions. Soft liners, moisture-retentive acrylics, and antimicrobial coatings are among the innovations improving both retention and comfort for SS patients. The aesthetic and functional outcomes of prosthetic solutions are also essential considerations. Enhanced retention mechanisms, such as implant-supported overdentures, not only improve masticatory performance but also aid in preserving the patient’s facial profile and lip support. Advanced materials offering translucency and color stability contribute to a more natural appearance, which is critical for patient satisfaction. The maintenance of these prostheses requires specific care routines to mitigate microbial buildup and tissue irritation. Specialized cleaning agents and salivary substitutes help maintain hygiene and reduce discomfort, while regular follow-up visits enable timely adjustments to accommodate tissue changes and extend the prosthesis lifespan. Implementing a comprehensive approach that considers material selection, functional and aesthetic outcomes, and maintenance strategies can greatly enhance the quality of life for SS patients. By understanding and addressing the specific needs associated with xerostomic conditions, dental professionals can provide prosthetic solutions that offer both reliability and comfort in this challenging context. Regular patient education and diligent care routines remain essential to ensure the long-term success and durability of removable dental prostheses for individuals with SS.

This research focuses on analyzing how different primary catalysts affect the glycolysis of plastic made from bisphenol A (PC) polycarbonate. It was found that the process of chemical decomposition of PC under the influence of ethylene glycol (EG) leads to the formation of products with high added value: bisphenol A (PC monomer, BPA), BPA, and ethylene carbonate or ethylene glycol co-ethers (BPA monohydroxyethyl ether, MHE-BPA; BPA bishydroxyethyl ether, BHE-BPA). A quantitative assessment of the yields of the reaction products was also carried out. The yield of products at 100% PC conversion was 33% for BPA, 50% for MHE-BPA, and 17% for BHE-BPA. The effectiveness of using various alkalis depending on the type of metal was also compared within the context of this investigation.

Published: October 2024

Background. It is shown that it is necessary to study the effect of atmospheric turbulence on the spectral characteristics of a radio signal. Aim. The influence of atmospheric turbulence on the spectral fluctuations of the radio signal intensity and on the displacement of the spectral components of the radio signal has been studied. Methods. The research was carried out on the basis of an analysis of the relationship between two-wave and single-wave correlation ratios. Based on the solution of the differential equation for fluctuations of the eikonal amplitude of an electromagnetic wave and the use of the derived trigonometric ratio, a connection between the two-wave Fourier=spectrum and single-wave spectra is obtained. In this case, a single source of turbulence effects on the radio signal was used at the coordinate point of the radio wave propagation by introducing a new variable equal to the average value of the coordinates of the turbulence effect. To find the resulting double integral, one of the coordinates of the turbulent action is transformed into an angular variable. Results. The dependence of the relative dimensionless mean of square of the integral intensity of the radio signal fluctuations on the wave number of turbulent pulsations of the atmosphere at various displacements of the spectral wavelengths of the radio signal is found. Conclusion. It is shown that turbulence slightly distorts the spectral information essence of a propagating radio signal in various wavelength ranges.

Authors: Semenov Petr A. , Zemlyakov Viacheslav V. , Vyatkina Svetlana A.
Published: October 2024

Background. Modern technologies in the field of optics and photonics place high demands on the quality and output power of the radiation source. The fulfillment of these requirements can currently be achieved by creating multi-aperture laser systems with coherent beam addition. The main problem of creating such systems is the development of phase synthesis methods in a multichannel optical system. Aim. In this paper, we consider a phase synchronization method without a reference beam for a coherent addition system with active feedback, which is based on the Gerchberg–Saxton algorithm. This algorithm makes it possible to reconstruct complex field amplitudes in the aperture and focal planes from intensity distributions in these fields. The application of this algorithm for multichannel systems is analyzed and its features, such as the occurrence of stagnation and ambiguity of the solution, are revealed. Methods. Solutions are proposed to eliminate the problem of convergence of the algorithm to side solutions and getting the iterative procedure into the local extremum using global optimization algorithms, methods of reducing the dimension of the problem and the introduction of antisymmetric amplitude modulation. Results. The paper demonstrates the results of phase field reconstruction for a large number of optical sources. For a seven-aperture system, a physical simulation was performed to restore phase information, confirming the results of numerical modeling. Conclusion. The proposed approach is a reasonable alternative to currently existing methods and can be used in the problem of coherent addition in multichannel optical systems.
Influence of density variations of ionosphere plasma on the conditions of electromagnetic whistler waves propagation in the ionosphere
Authors: Mizonova Vera G. , Degteryov Evgeniy G. , Sokolova Galina M.
Published: October 2024

Background. Plasma density variations caused by infrasonic wave can significantly affect conditions of propagation and reflection of whistler electromagnetic wave incident on the ionosphere from above. Aim. In that work, relationship between the coefficient of wave energy reflection from ionosphere, electromagnetic wave field near the ground surface and parameters of infrasonic wave are studied. Methods. The collocation method for solving the boundary problem for a plane-layered ionosphere and the perturbation theory method are used to find the electromagnetic wave field. Results. The greatest modulation of the reflection coefficient is associated with density perturbations at altitudes 80–110 km where whistler decay increases by an order of magnitude at the local altitude region (less than 15–20 km). In that case, the reflection coefficient variation can achieve 40 %. Conclusion. The results obtained are important for understanding the interconnection of magnetosphere radiation processes of different nature. The study of the modulation of coefficient of whistler reflection from the ionosphere is relevant for explaining the operation modes of a plasma magnetospheric maser.
Electrodynamic analysis of a sinusoidal antenna for small wave sizes
Authors: Tabakov Dmitry P. , Zondai Wadzanai J.
Published: October 2024

Background. The work is aimed at developing and researching rigorous methods for calculating thin-wire structures with a complex generatrix shape, having small wave sizes, as well as studying the physical processes occurring in them. A special case of such structures is a sinusoidal antenna operating in a standing current wave mode. Aim. In progress the solution of internal and external problems of electrodynamics is carried out for a sinusoidal antenna of small wave sizes located above an infinitely extended ideal reflector. The currents on the elements of the structure are calculated, its input resistance and radiation characteristics are determined. Methods. The research is based on a strict electrodynamic approach, within the framework of which, for the specified structure in the thin-wire approximation, an integral representation of the electromagnetic field is formed, which, when considered on the surface of conductors together with boundary conditions, is reduced to a system of Fredholm integral equations of the second kind, written relative to unknown current distributions on conductors (internal task). Results. A mathematical model of the radiating structure is proposed, determined: the input resistance of the structure and the basic characteristics of its radiation. It is shown that the operating range of a sinusoidal antenna in the standing wave mode is determined by the quality factor of the input impedance resonances; An increase in the width of the sinusoidal conductor leads to a decrease in the resonant frequencies of the input resistance with a simultaneous increase in the quality factor of the resonances. Conclusion. From a practical point of view, the use of the considered structure allows significantly reduce the dimensions in comparison with a thin electric vibrator, however in this case, the operating range will be correspondingly narrowed, which is determined, due to the weak dependence of the radiation characteristics on frequency, by the quality factor of the resonances. The current distribution on the generatrix of the structure can be considered as a «projection» standing surface wave localized in the plane of a sinusoidal conductor, and resulting from the superposition of forward and backward surface (slow) waves propagating at a speed significantly lower than the speed of light. To further clarify the physics of the processes occurring in the structure, one should use spectral analysis of current functions and study the distributions of the electromagnetic field in the near zone of the structure.

Published: October 2024

Background. The using of mirror asymmetric chemical compounds for doping quartz makes it possible to metamaterial creation that has the chirality property. In such a compositional structure, unusual effects may arise when interacting with an optical wave. Aim. We calculate the transmission and reflection of a linearly polarized optical wave through a multilayer structure consisting of two doped quartz glasses separated by two air gaps. Methods. Based on a homogeneous mathematical model of a chiral metamaterial, taking into account the dispersion of the dielectric constant and the chirality parameter based on the matrix method, a system of linear algebraic equations is obtained for the complex reflection and transmission coefficients of an electromagnetic wave of linear polarization. Results. An analysis of the frequency and angular characteristics of the modules of the reflection and transmission coefficients was carried out at various values of the quartz doping level. It is theoretically predicted that at some wavelengths, most of the incident optical energy can be concentrated in the air gaps of the multilayer structure. Conclusion. The data obtained as a result of calculations can be used in the development of planar structures for frequency-selective concentration of energy in the visible and infrared spectrum based on quartz glasses doped with chiral chemical compounds.

Published: October 2024

Introduction: The genus Rhodococcus, first described by Zopf in 1891, comprises 56 species with validly published names. This bacterium belongs to the phylum Actinobacteria, class Actinobacteria, order Mycobacteriales, and family Nocardiaceae. Notable characteristics of this bacterial genus include: Gram-positive, partially acid-fast positive, catalase-positive, non-spore-forming, and non-motile. The use of molecular methods such as 16S rRNA gene sequencing, along with phenotypic methods, has been suggested for the identification of this bacterium. To date, nine species of the genus Rhodococcus have been reported from clinical specimens. Currently, microbroth dilution is the standard method for assessing the antibiotic susceptibility testing of Rhodococcus species. The pattern of antibiotic resistance in Rhodococcus species varies based on geographical region, and it is recommended that antibiotic susceptibility testing be performed for clinical isolates.

Introduction: Since it is necessary to detect changes in lung function for the follow-up of the patients with respiratory and functional complications caused by COVID-19, in this study, we decided to examine the results of spirometry in children over 5 years old with Covid-19.
Methods: In this cross-sectional study, 52 over-five-year-old children, hospitalized due to COVID-19 for at least six past months, were examined. The participants’ demographic information, respiratory symptoms, underlying diseases, severity of COVID-19 according to WHO, severity of lung involvement in CT scan, type of lung involvement, oxygen saturation at admission as well as FEV1, FVC, and FEV1/FVC were collected and analyzed, the results were analyzed using SPSS version 16 software and t-test and Chi-square tests.
Results: Of all investigated patients،, 26 were boys (50%) and 38 (73.1%) were 5-12 years old. The minimum age of the children was 5 years and the maximum was 18 years. The mean age of children was 3.41±10 years. The FEV1/FVC ranged from 61% to 79% in five patients (9.6%) and from 80% to 100% in 47 patients (90.4%). The FEV1 was lower than 80% in 28 and higher than 80% in 24 patients. FEV1/FVC had no significant relationship with the participants’ age, gender, clinical manifestations, and disease severity in terms of pulmonary involvement, but it had a significant association with blood oxygen saturation level (P: 0.001).
Conclusion: The changes in pulmonary function tests vary in different months following contamination with COVID-19. In the present study, 9% of the patients, who were examined in the sixth month after infection, had abnormal pulmonary function test results. Based on the findings, the pulmonary function test results had no significant relationship with the patients’ age, gender, and clinical symptoms, while it was significantly associated with their blood oxygen saturation intensity.

Introduction: Myocardial ischemia-reperfusion injury is a set of cellular and molecular patho-mechanisms that lead to the death of living cardiomyocytes and compromised cardiac function. The aim of this study was to determine the effect of moderate intensity interval training on the expression of RIPK-1, RIPK-3 and MLKL genes in the heart of male heart attack model rats.
Methods: In this experimental study, thirty 16-week-old male Wistar rats weighing 220 to 280 gr were randomly divided into three groups: control (healthy), myocardial infarction (MI), and moderate intensity interval training. Myocardial infarction was performed by direct intervention with occlusion in the left anterior descending artery (LAD) for 30 minutes. Interval training protocol was performed three days a week, for 8 weeks, with moderate intensity of 60 minutes of interval running on a treadmill, each interval including 4 minutes of running with an intensity of 65-70% of VO2max and 2 minutes of active recovery with an intensity of 50-60% of VO2max. qRT-PCR method was used to check the gene expression of research variables. Data were compared using SPSS software version 16, one-way analysis of variance and Tukey's post hoc test at a significance level of p<0.05.
Results: The expression of cardiac RIPK-1, RIPK-3 and MLKL genes were higher in the MI group compared to the control group; however, moderate intensity interval training decreased the expression of RIPK-1, RIPK-3 and MLKL genes compared to the MI group (p=0.001 and p=0.006, respectively).
Conclusion: The results of the research showed that myocardial infarction is associated with the activation of the necroptosis cell death pathway, likewise, interval training with moderate intensity has an effect on reducing the expression of necroptosis genes (RIPK1, RIPK3, and MLKL). However, due to the lack of evidences and limitations of research, it still needs more investigations.

Comparative proteomics of snake and lizard venoms: Unveiling the molecular basis of venom diversity and adaptation
Authors: Wang Zejia
Published: October 2024

Venom protein profiling is a method used to analyze the composition and structure of proteins in venom. Venom contains a variety of neurotoxins and enzymatic proteins, which have toxic effects on human and animal organisms. By identifying the proteins in the venom, we can better understand the toxic mechanism of the venom, and provide important references for biomedical research and clinical treatment. The basic steps of venom protein profiling include sample preparation, mass spectrometry and data analysis. Based on this, the protein component analysis was carried out and the results were summarized. The diversity of snake venom and lizard venom can be explained by their protein composition and structure. Their differences at the protein level determine their different functions and pathways of action in toxicology, while also providing important resources for biodiversity and drug development.
