Treatment of patients with dental retention is an urgent task of orthodontics.
Aim: Determine the features of the etiology, diagnosis and treatment of patients with unilateral retention of the second premolar due to premature removal of milk molars.
Material and methods: 19 patients aged 14 to 19 years were examined and treated with unilateral retention of the second premolars after obtaining informed consent approved by the Ethics Committee. Methods of clinical examination generally accepted in dentistry with the analysis of anamnestic, radiological, biometric data were carried out. Biometrics of plaster models with asymmetrical arc shape was carried out on scaled (1:1) photographs with the application of the main landmarks on them.
Results: Unilateral retention of the second premolar, due to premature removal of the second milk molar, as a rule, contributes to the formation of asymmetric dental arches with a deviation of their main parameters from the individual norm. The change in diagonal dimensions is due to the displacement of the canines and the first molars towards the defect. At the same time, on the side of the impacted tooth, there is a violation of the closure of pairs of antagonist teeth and a shift in the line of the aesthetic center by an average of (2.38 0.61) mm. The stages of treatment include, firstly, the creation of conditions for the eruption of the impacted tooth with the subsequent restoration of occlusive balance.
Conclusion: Thus, the results of the study give us the basis for choosing methods for the diagnosis and treatment of asymmetric forms of dental arches caused by the retention of second premolars, which can be used in clinical orthodontics.

In modern plastic surgery of soft tissues of the oral cavity, there is a wide variety of ways to close recessions of the gingival margin and increase the keratinized gum zone, but only a few of them give a well-predicted and effective result. So, one of the most popular techniques is the tunneling technique using a de-epithelized free gingival graft. The prevalence of this method is primarily due to its minimally invasive nature, which allows for accelerated regeneration of the gingival margin and reduces the likelihood of postoperative complications. The analysis of 20 clinical cases of closure of recessions of the gingival margin of the teeth on the upper and lower jaws according to the Miller classification of class I and II, subclasses A and B and the Francesco Cairo classification type 1 and type 2 with the use of tunnel technology according to Zuhr. The high efficiency of this method of closing recessions has been revealed, including in terms of achieving an optimal long-term forecast and aesthetic result.

Face recognition systems have gained increasing importance in today’s society, which applications range from access controls to secure systems to electronic devices such as mobile phones and laptops. However, the security of face recognition systems is currently being threatened by the emergence of spoofing attacks that happens when someone tries to unauthorizedly bypass the biometric system by presenting a photo, 3-dimensional mask, or replay video of a legit user. The video attacks are perhaps one of the most frequent, cheapest, and simplest spoofing techniques to cheat face recognition systems. This research paper focuses on face liveness detection in video attacks, intending to determine if the provided input biometric samples came from a live face or spoof attack by extracting frames from the videos and classifying them by using the Resnet-50 deep learning algorithm. The majority voting mechanism is used as a decision fusion to derive a final verdict. The experiment was conducted on the spoof videos of the Replay-attack dataset. The results demonstrated that the optimal number of frames for video liveness detection is 3 with an accuracy of 96.93 %. This result is encouraging since the low number of frames requires minimal time for processing.

Cervical cancer is the most common type of cancer in women and the main reason people die from cancer in poor countries like Indonesia. Cervical cancer is a type of cancer that is caused by the Human Papillomavirus (HPV) and can be dangerous to a woman's health. Cervical cancer has the second most cases and deaths in the world, after breast cancer. The East Java Provincial Health Office's Health Profile for 2021 says that Trenggalek is an area with a low rate of cervical cancer screening. So, we started doing community service projects to make more people aware of cervical cancer. This community event began with drinks for the staff and a talk about cervical cancer and how to find it early. Some of the things that are done are health education about cervical cancer and ways to find it early. During this practice, women of reproductive age (WUS) were also asked to take part in a free Visual Acetate Acid (VIA) test done by the team. The next event was a free VIA test, which 21 WUS students took part in. The results of the VIA test showed that 20 people had bad VIA and one person had good VIA. The team then sent people who had a good VIA to get more care. Women, cadres, and other important people in the community can learn more about cervical cancer through community service. However, community service in other areas is needed in the coming year so that this issue can be brought up and the community can benefit from it, especially since cervical cancer is on the rise. People also think that this would change how women with cervical cancer get their treatments and improve their quality of life.

The problem of decreasing perinatal mortality is one of the pressing problems in modern obstetrics. Unfortunately, current methods of monitoring the intrauterine state of the fetus that are at the disposal of an obstetrician – gynecologist (сardiotocography, Doppler velocimetry) do not guarantee fetal wellbeing in the near-term outlook, and the number of tests is limited due to safety concerns. Consequently, there is ongoing search for alternative methods of obtaining information about the intrauterine state of the fetus (phonocardiography, electrocardiography). Using IT and mathematical data analysis has considerably enlarged the phonocardiography potential, including implementation of remote monitoring of the fetal health state.

A Tomsk-based company Diagnostika + LCC developed software and hardware appliance FetalCare aimed at 24-hour monitoring of the intrauterine state of the fetus based on audio data on the fetal cardiovascular system. Cardiointervalograms (CIG) obtained by phonocardiography allow to estimate the state of the fetus based on standard assessment criteria: basal heart rate, heart rate variability, presence of accelerations and decelerations, short-term variation (STV), and long-term variation (LTV). The developed appliance is non-invasive, relatively cheap, portable, and safe both for the mother and the fetus.

Published: October 2023

Aim. To assess the association of the MnSOD (rs4880) and GPX1 (rs1050450) gene polymorphisms with a risk of developing chronic dust-induced bronchitis in workers of the coal mining industry.

Materials and methods. The study included 182 coal miners with prolonged exposure to high concentrations of coal dust, including 116 people with a previously established diagnosis of chronic dust-induced bronchitis (CDB) and 66 people without pathology of the bronchopulmonary system, working under the same sanitary and hygienic conditions. Polymorphisms of the MnSOD (rs4880) and GPX1 (rs1050450) genes were studied using polymerase chain reaction.

Results. For the first time, we established a statistically significant association between the polymorphisms of the MnSOD (rs4880) and GPX1 genes (rs1050450) and CDB. Thus, the chance of detecting the homozygous A/A (Val/Val) MnSOD genotype in miners with CDB was 2 times higher than in the comparison group ( χ2 – 5.42; р = 0.02; odds ratio (OR) 2.21; 95% confidence interval (CI) 1.13–4.33), while the chance of detecting the homozygous G/G (Pro/Pro) GPX1 genotype in miners with CDB was almost 6 times higher than in the comparison group (χ2 – 21.47; р = 0.001; OR 5.89; 95% CI 2.65–13.08). It was found that the combination of AA/GG genotypes of the MnSOD/GPX1 genes was significantly associated with a 1.5-fold risk of developing CDB (χ2 – 11.49; р ˂ 0.001; relative risk (RR) 1.59; 95% CI 1.36–1.84), while the chance of detecting this combination of genotypes in miners with bronchopulmonary pathology was 15 times higher than in the comparison group (OR 15.09; 95% CI 1.99–114.64).

Conclusion. Carriage of homozygous genotypes A/A at the rs4880 MnSOD locus and G/G at the rs1050450 GPX1 locus was shown to be a marker of genetic predisposition to the development of CDB. The combination of homozygous genotypes of the studied AA/GG MnSOD/GPX1 genes indicated a 1.5-fold risk of developing CDB. Carrying one of the three combinations of the MnSOD and GPX1 genotypes (GG/AA, AA/AA, and AG/AA) indicated resistance to the development of CDB.

Published: October 2023

We previously developed a highly sensitive and specific anti-PDPN mAb, LpMab-23 (mouse IgG1, kappa). In this study, we produced a humanized IgG1 version (humLpMab-23) and its defucosylated form (humLpMab-23-f) of an anti‑PDPN mAb to potentiate the ADCC activity. The humLpMab-23 could recognize PDPN‑overexpressed Chinese hamster ovary (CHO)-K1 (CHO/PDPN) and PDPN-positive PC-10 and LN319 cells by flow cytometry. Furthermore, we found that humLpMab-23-f exerted ADCC and complement-dependent cytotoxicity against CHO/PDPN, PC-10 and LN319 cells in vitro and exhibited potent antitumor activities in the xenograft models. These results indicated that humLpMab-23-f could be useful for an antibody treatment regimen for PDPN-positive human cancers.

In road construction, before applying an asphalt or concrete surface, the ground must be compacted and stabilized. There are two basic methods of soil stabilization: in situ and in a stationary node (ex-situ). The method of performing stabilization in place (in-situ) is the most frequently used method due to its convenience and lower price. The most popular type of binder for stabilization is a hydraulic binder (most often cement and various ashes). Such stabilization is performed at a depth of 10-50 cm, achieving the desired load-bearing parameters. In order to improve them, various chemical additives for stabilization are often used, such as ion exchange compounds, additives based on sulfuric acid, additives based on vinyl polymers or even organic additives using lignosulfonates. However, the use of such additives is associated with much greater costs and environmental burden, resulting in seeking for cheaper and equally effective alternatives. The win-win situation would be for instance recycling the problematic waste-based materials that on one hand are landfilled or impossible to recycle and on the other hand cause problems for the waste producers. Therefore, an interesting issue is the production of stabilization additives from various types of waste materials. As a result of the extensive testing of various waste-based materials blends with soil, the mechanical (compressive strength after 7 and 28 days) and hydraulic (capillary rise, water absorption, frost resistance) soil properties were measured. The optimization process led to obtaining additives compositions ensuring the best strengthening and sealing properties. These were for sandy soil: Pure foil (wax emulsion), Pure foil (wax emulsion) + waste sulphuric acid, RDF from waste tires (wax emulsion), Pure foil (wax emulsion) + “by-pass” waste ash + NaOHx2 and for clayey soil: Pure foil (wax emulsion) + NaOH, Pure foil (wax emulsion) + waste sulphuric acid, Tequant, Pure foil (wax emulsion).

An especially important species in southern Brazil, yerba mate (Ilex paraguariensis) is traditionally consumed as tea, chimarrão and tererê. Yerba mate consumption has been stimulated by scientific discoveries that have identified high concentrations of bioactive compounds and their health benefits. There are no studies or scientific evidence to certify or guarantee stability of these compounds’ concentrations during different years in the same plants. We were interested in quantifying caffeine, theobromine, total phenolic compounds and proteins concentrations in leaves of yerba mate genotypes and their stability in the same plants over four consecutive years. Mature leaves from yerba mate genotypes selected on a provenance and progenies trial were collected in August of 2015, 2016, 2017 and 2018. Methylxanthines (caffeine and theobromine), total phenolic compounds and total protein contents were quantified. Our results indicate large variations between genotypes regarding caffeine (0.035 to 2.385 g 100 g-1), theobromine (0.0004 to 1.772 g 100 g-1), total phenolic compounds (7.028 to 9.424 g 100 g-1) and proteins (10.39 to 16.58 g 100 g-1) contents, and also high stability of those compounds over the four evaluated years. A great variation of the studied bioactive compounds in different Ilex paraguariensis genotypes was found and its stability over four consecutive years was showed.

Researchers are increasingly focusing on green synthesis methods for silver nanoparticles due to their cost-effectiveness and reduced environmental impact. In this study, we utilized an edible bird's nest (EBN), a valuable economic resource, as the primary material for synthesizing silver nanoparticles using only water as the solvent. Metabolite profiling of the EBN extract was conducted using LC-QTOF-MS in positive mode (ESI+), revealing the presence of lipids, glycosides, peptides, polysaccharides, and disaccharides. Upon the addition of silver nitrate to the aqueous EBN extract, noticeable color changes from transparent to brown indicated the successful formation of AgNPs. Subsequent characterization of these silver nanoparticles involved UV-Visible spectroscopy, which revealed an absorption peak at 421 nm. Further characterization was carried out using Field Effect Scanning Electron Microscopy (FESEM), Attenuated Total Reflectance-Fourier Infrared (ATR-FTIR) spectroscopy, and Energy Dispersive X-Ray (EDX) analysis. The involvement of phenolic agents, proteins, and amino acids in reducing the silver particles was confirmed. The synthesized nanoparticles exhibited a crystalline nature, a spherical shape, and a particle size ranging from 10 to 20 nm. The presence of elemental silver was confirmed by a strong, intense peak around 3 keV in the EDX spectrum. To assess their potential, the antibacterial properties of the silver nanoparticles against Escherichia coli and Staphylococcus aureus were evaluated using the agar diffusion method.

The anterior cruciate ligament (ACL) injury in the knee is one of the most frequent injuries in the biomechanical environment during jumping exercises; however, repeated jumping, like jumping rope, has not been reported to have a significant impact on the ACL injury. Because of this, this study aimed to compare and examine any potential biomechanical risk factors that can arise during various jumping rope activities, including the basic bounce (BB), forward-backward jump (FB), side-to-side jump (SS), and high knee jump (HK). Thirty participants were recruited. A motion capture system was used to obtain synchronized kinematic and kinetic data for four different jumping rope techniques. The OpenSim modeling system was used to determine the biome-chanical knee factors. The paired samples t-test was used to compare the mean difference in each jumping rope technique of initial contact (IC) and maximum knee flexion (MKF), and a one-way ANOVA was used to compare the mean difference between four different jumping rope techniques in the IC-MKF phase. Between IC and MKF, knee flexion angle, moment, joint ground reaction forces (GRF), and muscle forces of four jumping rope techniques were significantly different (p <.05). Also, in the IC-MKF phase, knee flexion angle and knee extension moment; HK was lower than others; vertical GRF; HK and FB were higher than others; anteroposterior, mediolateral GRF, and muscle forces; SS was higher than others (p <.05). Depending on the jumping rope techniques, the lower knee flexion angle in HK, the higher knee vertical GRF in HK and FB, the higher knee extension moment, anteroposterior, mediolateral GRF, and muscle forces on SS could be a pos-sibility of ACL injury risk compared to others. Therefore, it is recommended that SS be used in risk assessment of ACL in future studies, and BB will be suitable for normal people in daily exercises or will be the alternative intervention program for knee rehabilitation with the lowest risk of injury.

Published: October 2023

Biological, environmental, behavioral, and social factors can influence sleep and lead to sleep disorders or diseases. Sleep disorders are common, numerous and heterogeneous in terms of their etiology, pathogenesis, and symptomatology. Management of sleep-wake circadian disorders (SWCD) includes education to sleep hygiene, behavioral strategies, psychotherapy (cognitive behavioral therapy (CBT), particularly), instrument-based treatments (i.e. positive airway pressure therapy, hypoglossal nerve stimulation), and pharmacotherapy. Depending on the disease, therapy varies and is executed sequentially, or can be a combination of several forms of therapy. Drugs used for SWCD include traditional sleep or wake-promoting agents, chronotherapeutic agents. Recently, novel medications, which are more precisely acting on specific neurochemical systems (i.e. orexin system) important for sleep and wake, are also increasingly being used. In this review, the pharmacotherapy of common sleep disorders (insomnia, sleep-related breathing disorder, central disorders of hypersomnolence, circadian rhythm sleep wake disorders, parasomnias, and sleep-related movement disorders) embedded in the overall therapeutic concept of each disorder is presented. There is also an outlook on possible future pharmacotherapies.

Knowledge of water availability in terms of spatial (i.e., depth) and temporal variability of soil water is essential to describe soil water infiltration and storage processes accurately. Therefore, performing simulations of soil water dynamics can be a valuable tool to evaluate different land uses and their impact on water availability. Consequently, this study aimed to model the volumetric soil water content (θ, cm3 cm-3) under agroforestry systems (AFS) with cocoa. For this purpose, the θ was monitored at different depths (0-20, 20-40, 40-60, 60-80, 80-100 cm) in the soil profile of four plots (20 × 50 m) of cocoa under agroforestry systems. Environmental conditions significantly influenced the water balance of the cocoa crop. There were seven moments when evapotranspiration (ET0) was higher than 5 mm d-1. During those moments, the environment exhibited higher PAR values of 1041 µmol m-2 s-1, very low atmospheric relative humidity (RHa) levels (around 45%), higher ambient temperatures of 32.2 ºC and a vapor pressure deficit of 1.6 kPa whose θ levels reached 0.32 cm3 cm-3 and a water balance of -5.7 mm, which presented negative values during most of the study period. The θ obtained from the HYDRUS-1D model presented a slight bias as a high level of coherence between the observed values, based on the model's goodness-of-fit estimators. The above provides accurate simulations of soil water content at various depths, much-needed information for management schemes for cocoa cultivation under agroforestry systems.
Psychosocial Occupational Health—A Priority for Middle-Income Countries?
Authors: Siegrist Johannes
Published: October 2023

In response to new developments of work and employment in high-income countries (HICs), psychosocial aspects of work and health received increased attention. In contrast, middle-income countries (MICs) are mainly concerned with severe challenges of noxious and dangerous material work environments, poor employment conditions, and deficient social policies, leaving psychosocial aspects in a marginal role at best. More recently, differences between these two worlds were even aggravated by the COVID-19 pandemic. Yet, with economic globalisation and growing worldwide interconnectivity, the world of work in MICs is being rapidly transformed, sharing several concerns with modern Western societies. In this process, psychosocial occupational health will become an increasingly pressing issue. This contribution explores to what extent psychosocial aspects of work and health are already addressed in research originating from MICs. A selective focus on recent findings from two regions, Asia Pacific and Latin America, reveals a high degree of awareness of, and inquiry into, work-stress related problems within these countries. Importantly, in addition to incorporating research progress from HICs, these analyses identify new aspects within specific cultural and socio-economic environments, thus enriching the international state of art.

In this study, cotton fabric reinforced phenolic resin (CPF) composites were modified by adding four two-dimensional fillers: graphitic carbon nitride (g-C3N4), graphite (Gr), molybdenum disulfide (MoS2), and hexagonal boron nitride (h-BN). The tribological properties of these modified materials were investigated under dry friction and water lubrication conditions. CPF/ Gr composite exhibits significantly better tribological performance than the other three fillers modified CPF composites under dry friction, with a 24% reduction in friction coefficient and a 78% reduction in wear rate compared to unmodified CPF composite. Under water lubrication conditions, all four fillers did not significantly alter the friction coefficient of the CPF composite. However, except for an excessive amount of Gr, the other three fillers can reduce the wear rate. Particularly, in the case of 10% MoS2 content, the wear rate decreased by 56%. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) were employed for the analysis of the morphology and composition of the transfer films. Additionally, molecular dynamics (MD) simulations were conducted to investigate the adsorption effects of Gr, MoS2, and PF on the counterpart surface under both dry friction and water lubrication conditions. The difference in the adsorption capacity of Gr and MoS2 on the counterpart, as well as the resulting formation of transfer films, accounts for the variation in tribological behavior between CPF/Gr and CPF/MoS2 composites. By combining the lubrication properties of MoS2 and Gr under dry friction and water lubrication conditions, using them as co-fillers can achieve a synergistic lubrication effect.
