Published: December 2023

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia. The development of diabetic complications plays a pathological role in increasing Reactive Oxygen Species (ROS) levels, which induce oxidative stress. The aim of this study was to examine the antidiabetic activities of kemuning and moringa leaves based on glucose, SOD, and GPx levels, and the protective activity of pancreatic cells in STZ-NA-induced rats. The kemuning and moringa leaves were dried, finely powdered, and extracted by the remaceration method using 96% ethanol. The test was carried out on 30 rats that were divided into 6 treatment groups, namely the normal control group, negative control, positive control (glibenclamide), extract dose of 76.5 mg. /200 g BW : 6.5 mg/200 g BW, 114.75 mg/200 g BW : 3.25 mg/200 g BW and 38.25 mg/200 g BW : 9.75 mg/ 200 g BW. The antidiabetic test was carried out using STZ-NA, glucose levels were measured, and SOD and GPx levels in the liver supernatants were measured. Cell protection was tested using the cell damage score method. The data obtained were analyzed using one-way ANOVA variance. The results showed that kemuning and moringa leaves at a dose of 38.25 mg/200 g BW: 9.75 mg/200 g BW were able to lower blood glucose levels, increase the activity of SOD and GPx, and protect pancreatic cell damage in STZ-NA rats.

Цель исследования — проанализировать обусловленность изменения положения третьих моляров (ТМ) с возрастом. Проанализированы более 3000 ортопантомограмм (ОПТГ) челюстей пациентов в возрасте от 7 до 25 лет с различными аномалиями зубочелюстной системы: скученное положение зубов, сужение зубных рядов, мезиальная и дистальная окклюзия. Изучали стадии формирования ТМ, угол их наклона и их расположение относительно биссектрисы гониального угла и контрфорсов верхней и нижней челюсти. Контрфорсы на верхней челюсти располагаются вертикально и не препятствуют правильному прорезыванию зубов. При расстоянии от контрфорса до зачатка нижнего ТМ более 2,0 мм и угле наклона более 70° возможно его прорезывание, а при отсутствии расстояния и угле наклона менее 70° целесообразно удалять эти зубы (патент № 2778775, действ. с 28.12.2020). Расстояние от коронок нижних ТМ относительно биссектрисы гониального угла и угол наклона моляров с возрастом уменьшаются. Анализ корреляционных связей параметров ОТПГ челюстей показал значимую взаимосвязь таких показателей как возраст, положение и угол наклона ТМ, величина гониального угла и стадия формирования корней моляров.

The aim of the study is to analyze the conditionality of changes in the position of the third molars (TM) with age. . More than 3000 orthopantomograms (OPTG) of the jaws of patients aged 7 to 25 years with various anomalies of the maxillary system were analyzed: crowded position of teeth, narrowing of dentition, mesial and distal occlusion. The stages of TM formation, their angle of inclination and their location relative to the bisector of the gonial angle and buttresses of the upper and lower jaws were studied. . Buttresses on the upper jaw are arranged vertically and do not prevent proper teething. If the distance from the buttress to the rudiment of the lower TM is more than 2.0 mm and the angle of inclination is more than 70°, its eruption is possible, and if there is no distance and the angle of inclination is less than 70°, it is advisable to remove these teeth (patent No. 2778775, effective from 12.28.2020). The distance from the crowns of the lower TM relative to the bisector of the gonial angle and the angle of inclination of the molars decrease with age. . The analysis of correlations between the OPTG parameters of the jaw showed a significant relationship between such indicators as age, the position of the third molars, the angle of inclination of the third molars, the value of the gonial angle and the stage of formation of molar roots.

Цель работы — оценка качества лечебных мероприятий, связанных с реставрационным лечением дефектов твердых тканей боковых зубов с точки зрения выявления ятрогенных причин первичной травматической окклюзии. Обследовано 306 человек с физиологическими формами прикуса, из них выделены 4 группы в зависимости от наличия и этиологических причин (ятрогения, связанная с некорректным реставрационным лечением дефектов твердых тканей боковых зубов, влияние 3-х моляров и комбинация этих двух факторов) первичной окклюзионной травмы. Установлено, что только 45 (14,7%) человек не имели симптомов первичной травматической окклюзии, у всех остальных 261 (85,3%) обследованных были выявлены нарушения окклюзионного рельефа боковых зубов различного генеза. Не соответствовали требованиям 76,5% всех имеющихся пломб, в большинстве случаев по качеству моделировки окклюзионной поверхности, по контактному пункту, по наличию краевой щели. Это позволяет утверждать, что многие стоматологи при реставрации восстанавливают рельеф зуба без учета морфологии окклюзионной поверхности и корректного взаимоотношения с антагонистами. Выявлены наиболее частые симптомы первичной травматической окклюзии: фасетки стирания твердых тканей, трещины эмали, клиновидные дефекты, изменение десневого края и пародонтальные карманы, супраконтакты на рабочей или на балансирующей сторонах. Ятрогенные причины нарушений окклюзионного рельефа можно рассматривать не только как дефект оказания медицинской помощи, но и как потенциальную причину тяжелых стоматологических заболеваний в отдаленные сроки.

The aim of this study is to assess the quality of posterior teeth restorations in to identify the iatrogenic cause of primary traumatic occlusion. . 306 participants with physiological bite were examined. They were separated into 4 groups according to iatrogenic factors: unacceptable posterior restorations, 3-rd molar affection, combination of these factors. . Only 45 (14.7%) people did not have symptoms of primary traumatic occlusion, all the other examined (261 people, or 85.3%) had violations of occlusal relief of posterior teeth of various origins. It was found that 76.5% of fillings did not meet clinical requirements, in most cases due to poor representation of occlusal surface, contact point, presence of a marginal gap. It can be explained that many dentists do not pay attention to morphology of occlusal surface and correct relation with antagonists. The most common symptoms of primary traumatic occlusion were: hard tissue abrasion facets, enamel cracks, wedge-shaped defects, changes in the gingival margin and periodontal pockets, supracontacts on the working or balancing sides. . Authors considered that iatrogenic unacceptable occlusal relief should be interpreted not only as a mistake, but also as a potential cause of severe dental diseases in long term.

Published: December 2023

Çalışma, beslenmenin nutrigenetik ve nutrigenomik bakımından sporcularda oluşturduğu etkileri incelemek amacıyla yapılmıştır. İnternet veri tabanlarına kayıtlı alana özgü çalışmalar incelenmiş ve özetlenmiştir. Omiks teknolojilerinde yaşanan gelişmeler sonucunda bireyselleştirilmiş diyet yaklaşımları ve beslenme stratejileri, önemli uygulamalar hâline gelmiştir. Bu alanlardan biri olan sporda beslenme, sporcuların sağlıklarını korumak ve performanslarını artırmak için anahtar role sahip bir beslenme türüdür. Bu amaçla makro ve mikro besin maddeleri, sporcu beslenmesinde önemlidir.

Sporcu beslenmesi üzerinde etkili olabilecek içsel-dışsal birçok faktör bulunmaktadır. Bu faktörlerden biri olan genetik, sporcu beslenmesinde dikkate alınması gereken önemli bir husustur. Sportif performans, besin maddelerinin metabolizmadaki etkinliği ile bu maddelerinin insan genomundaki ekspresyon seviyesi ile ilgili bir durum olabilir. Bu amaçla nutrigenetik ve nutrigenomik kavramları, sporcu performansı açısından dikkate alınması gereken konulardır. Çalışmada, nutrigenetik ve nutrigenomik kavramlarının teorikte aynı ama içerikte bazı farklılıklara sahip olabildikleri sonucu görülmüştür.

Sonuç olarak, sportif performans yalnız besin maddelerinin sporcu genomundaki metabolizmal faaliyetleri ile ilgili bir durum olmayabilir. Sportif performansı etkileme gücüne sahip içsel-dışsal birçok faktör bulunmaktadır.

Published: December 2023

Our aim in this study is examining the frequency of posterior communicating artery (PCoM), Anterior Cerebral Artery A1 segment (ACA AI) and Fetal type posterior cerebral artery (FPCA) anomalies and their effects on ischemic stroke by retrospectively analyzing examinations of Computerized Tomography Angiography (CTA) taken in our hospital within 2017. 22 cases (26.5%) diagnosed with bilateral hypoplastic / aplastic PCoA anomaly, were diagnosed with anterior circulation infarct, 24 cases (28.9%) were diagnosed with posterior circulation infarct, but 37 cases (44.6%) were not diagnosed with ischemic stroke. 17 (37.8%) of the cases who have unilateral hypoplastic / aplastic PCoA anomaly, were diagnosed with anterior circulation infarct, 14 cases (31.1%) were diagnosed with posterior circulation infarct. 13 (26%) of 50 cases diagnosed with unilateral hypoplastic / aplastic ACA A1 segment, were diagnosed with anterior circulation infarct, 10 cases (20%) were diagnosed with posterior circulation infarct. 27 cases (54%) were not diagnosed with ischemic stroke. Both of 2 cases diagnosed with bilateral hypoplastic / aplastic ACA A1 segment, had anterior circulation infarct. 4 (30.8%) of 13 cases diagnosed with unilateral FPCA anomaly, were diagnosed with anterior circulation infarct, 3 cases (23.1%) were diagnosed with posterior circulation infarct, 6 cases (46.2%) did not have ischemic stroke symptoms. In conclusion, even though these variations’ role in optimum stroke prophylaxis in individuals having one or more stroke risk factors, has not determined yet, there is no doubt that clinical researcher will eliminate these uncertainties in future studies.

Authors: Rogal M. M. , Lebedev A. G. , Yartsev P. A. , Stinskaya N. A.
Published: December 2023

Aim. To enhance the outcomes of treating patients with acute non-occlusive mesenteric ischemia (focal) following colostomy, aiming to gain a better understanding of the prevalent risk factors for complications and exploring ways of their reduction.

Materials and methods. A clinical case detailing the treatment of a patient with acute non-occlusive mesenteric ischemia amidst abdominal sepsis and stoma necrosis, compounded by inflammatory disease of the spinal cord membranes, is presented. Additionally, the clinical observation of a patient experiencing postoperative complications, including coronavirus infection and bilateral hydrothorax, is provided.

Results. In a patient presenting severe coronary pathology alongside a nuanced clinical manifestation of mesenteric ischemia in the delayed phase, a surgical intervention involving intestinal tract resection and subsequent stoma removal was conducted. Regrettably, stoma necrosis ensued, necessitating reconstructive surgery. The patient’s initial critical state, compounded by the requirement for repeated surgical intervention, precipitated a swift progression of multiple organ failure, culminating in mortality. Conversely, another patient, postoperatively diagnosed with coronavirus infection and bilateral hydrothorax, exhibited amelioration in clinical status following administered treatment, ultimately warranting hospital discharge.

Conclusions. Early diagnosis and timely surgical intervention contribute to improving the prognosis of treatment. Early postoperative complications and repeated surgical interventions significantly worsen the prognosis.

Aim. To investigate potential strategies for enhancing the treatment outcomes of patients with fractures and injuries to the proximal humerus through delayed reverse endoprosthesis.Materials and methods. From 2014 to 2022, reverse shoulder endoprosthesis (RSE) was performed on 64 patients aged 44 to 85 with fractures and dislocations. Among them, 39 patients were classified as elderly (60—74 years) at the time of surgery. Specifically, 22 patients underwent RSE within the first 6 months after the injury, 15 within the period from 6 to 12 months post-injury, and 27 were operated on no earlier than a year after the injury. Radiographs were analyzed, and postoperative complications and treatment results were evaluated before surgery, as well as at 3, 6, 12, and 24 months using the Constant Shoulder Score, UCLA, and ASES questionnaires.Results. Over a 2-year period post reverse shoulder endoprosthesis (RSE), there was a notable improvement in average scores across all assessment scales: Constant Shoulder Score improved from 18.2 ± 10.5 to 69.9 ± 20.7 points; ASES increased from 22.0 ± 10.3 to 82.0 ± 14.4 points, and UCLA rose from 14.7 ± 21.3 to 27.8 ± 5.92 points.Conclusions. Performing reverse shoulder endoprosthesis in patients with fractures and fractures-dislocations of the humerus in the delayed period allows achieving better treatment outcomes. Reverse shoulder endoprosthesis is a complex operation and is associated with a fairly large number of complications. Hence, engaging surgeons with expertise in such procedures is recommended.

Authors: Sanii Ryan Y. , Kasto Johnny K. , Wines Wade B. , Mahylis Jared M. , Muh Stephanie J.
Published: December 2023

Objective:

Literature reviews are essential to the scientific process and allow clinician researchers to advance general knowledge. The purpose of this study was to evaluate if the artificial intelligence (AI) programs ChatGPT and Perplexity.AI can perform an orthopedic surgery literature review.

Materials and Methods:

Five different search topics of varying specificity within orthopedic surgery were chosen for each search arm to investigate. A consolidated list of unique articles for each search topic was recorded for the experimental AI search arms and compared with the results of the control arm of two independent reviewers. Articles in the experimental arms were examined by the two independent reviewers for relevancy and validity.

Results:

ChatGPT was able to identify a total of 61 unique articles. Four articles were not relevant to the search topic and 51 articles were deemed to be fraudulent, resulting in 6 valid articles. Perplexity.AI was able to identify a total of 43 unique articles. Nineteen were not relevant to the search topic but all articles were able to be verified, resulting in 24 valid articles. The control arm was able to identify 132 articles. Success rates for ChatGPT and Perplexity. AI were 4.6% (6 of 132) and 18.2% (24 of 132), respectively.

Conclusion:

The current iteration of ChatGPT cannot perform a reliable literature review, and Perplexity.AI is only able to perform a limited review of the medical literature. Any utilization of these open AI programs should be done with caution and human quality assurance to promote responsible use and avoid the risk of using fabricated search results. [

Published: December 2023

The article presents the results of a study of the influence of B, Bi, Ca, Sn, and Sb additives on the structure, composition, and properties of individual phases and mechanical properties of castings made of hypereutectic high-chromium cast iron (HCCI), similar in composition to G-X300CrMo27-1 cast iron. Additives of these elements were introduced into the melt before cooling at an amount of 0.2 wt.%. The ingots were obtained at a melt cooling rate in the crystallization range of 0.083–0.116 ℃/s and at 4.67–5 ℃/s. When studying the structure, the parameters and proportion of primary carbides, and the proportion of eutectic carbides were determined and a description was given of the change in the austenitic matrix. Using microprobe analysis and microhardness measurements, changes in the composition and hardness of primary, eutectic carbides and the matrix were determined. Hardness HV, bending strength, and abrasive wear resistance were determined. It has been shown that depending on the cooling rate, the effect of these additives on the structure and properties of castings changes. The mechanism of influence of these elements on the process of crystallization of primary carbides in HCCI is considered. Based on the data obtained, it is proposed to use Ca as a modifying additive when producing castings from HCCI of a hypereutectic composition under slow cooling conditions, and B under fast cooling conditions. This makes it possible to increase the wear resistance of castings.
An analytic pricing formula for timer options under constant elasticity of variance with stochastic volatility
Authors: Choi Sun-Yong , Kim Donghyun , Yoon Ji-Hun
Published: December 2023

Timer options, which were first introduced by Société Générale Corporate and Investment Banking in 2007, are financial securities whose payoffs and exercise are determined by a random time associated with the accumulated realized variance of the underlying asset, unlike vanilla options exercised at the prescribed maturity date. In this paper, taking account of the correlation between the underlying asset price and volatility, we investigate the pricing of timer options under the constant elasticity of variance (CEV) model, proposed by Cox and Ross [10], taking advantage of the approach of asymptotic analysis. Additionally, we validate the pricing precision of the approximate formula for timer options using the Monte Carlo method. We conduct numerical experiments based on our corrected prices and analyze price sensitivities concerning various model parameters, with a focus on the value of elasticity.
Response of vegetation pattern to climate change based on dynamical model: Case of Qinghai Lake, China
Authors: Liang Juan , Ma Huilian , Yang Huanqing , Guo Zunguang
Published: December 2023

The global climate has undergone great changes in recent decades, which has a significant impact on the vegetation system, especially in arid and semi-arid areas. Based on a dynamic model, this paper studied the response of vegetation pattern to climate change in Qinghai Lake, a typical semi-arid region. The conditions for Turing instability of the equilibrium were obtained by mathematical analysis. The numerical experiments showed the influence of different climitic factors (carbon dioxide concentrations [$ CO_2 $], temperature and precipitation) on vegetation pattern. The results showed that the robustness of the vegetation system was enhanced as precipitation or [$ CO_2 $] increased. Furthermore, we presented evolution of vegetation system under different climate scenarios to forecast the future growth of vegetation. We compared the various climate scenarios with representative concentration pathways (RCP2.6, RCP4.5, RCP8.5). The results revealed that RCP2.6 scenario was a desired climate scenario for Qinghai Lake. Our study also highlighted the measures to avoid desertification by the method of optimal control. We expect that this study will provide theoretical basis for vegetation protection.
Nonlinear extended state observer based control for the teleoperation of robotic systems with flexible joints
Authors: Yan Yongli , Liu Fucai , Ren Teng , Ding Li
Published: December 2023

The control of robot manipulator pose is significantly complicated by the uncertainties arising from flexible joints, presenting substantial challenges in incorporating practical operational constraints. These challenges are further exacerbated in teleoperation scenarios, where factors such as synchronization and external disturbances further amplify the difficulties. At the core of this research is the introduction of a pioneering teleoperation controller, ingeniously integrating a nonlinear extended state observer (ESO) with the barrier Lyapunov function (BLF) while effectively accommodating a steady time delay. The controller in our study demonstrates exceptional proficiency in accurately estimating uncertainties arising from both flexible joints and external disturbances using the nonlinear ESO. Refined estimates, in conjunction with operational constraints of the system, are integrated into our BLF-based controller. Consequently, a synchronized control mechanism for teleoperation is achieved, exhibiting promising performance. Importantly, our experimental findings provide substantial evidence that our proposed approach effectively reduces the tracking error of the teleoperation system to within 0.02 rad. This advancement highlights the potential of our controller in significantly enhancing the precision and reliability of teleoperated robot manipulators.
