The object of the study was senile people, who sought dental orthopedic care in municipal healthcare institutions of the town of Cheboksary, the Chuvash Republic. The sample size was 1 000 people. The obtained quantitative indicators were subjected to statistical processing using parametric and nonparametric statistical methods. The analysis of mounted orthopedic dent prosthetic structures manufactured and installed in elderly and senile patients shows that the choice of material and method of manufacture is largely determined by such a social factor as the average monthly income. This, in turn, largely depends on income-generating employment and the possibility of obtaining additional fi nancial support from family members in which the patient lives. Social factors have a significant impact on the quality of life in elderly and senile people.
Объектом изучения стали люди пожилого и старческого возраста, обратившиеся за стоматологической ортопедической помощью в муниципальные учреждения здравоохранения (Чебоксары, Чувашская Республика). Размер выборки составил 1 тыс. человек. Полученные количественные показатели были подвергнуты статистической обработке с использованием параметрических и непараметрических методов. Проведенный анализ установленных ортопедических зубопротезных конструкций, изготовленных и установленных пациентам пожилого и старческого возраста, показал, что выбор материала и способа изготовления во многом определяется таким социальным фактором, как среднемесячный доход. Это, в свою очередь, во многом зависит от трудовой занятости, приносящей доход, и возможности получения дополнительной финансовой поддержки от членов семьи, в которой пациент проживает. Социальные факторы оказывают существенное влияние на качество жизни людей пожилого и старческого возраста.

Церебральная болезнь мелких сосудов является клинико-радиологическим феноменом, часто встречающимся у лиц пожилого возраста. Вопрос о количественных показателях поражения белого вещества у пациентов с умеренными когнитивными нарушениями сосудистого генеза в настоящий момент остается открытым. Недостаточно изучена и взаимосвязь степени нарушений когнитивных функций и объема поражения белого вещества. Цель исследования — проанализировать объемы поражения белого вещества головного мозга у пациентов с подкорковыми сосудистыми умеренными когнитивными расстройствами (псУКР) и в контрольной группе по данным МРТ. В исследование были включены 50 человек: 25 — с псУКР (средний возраст — 75,88±4,04 года) и 25 — условно-здоровых добровольцев (средний возраст — 69,96±3,07 года). Получены значимые различия в объёме поражения белого вещества между обследуемыми группами. Фракция гипоинтенсивного белого вещества составила 0,74±0,41 у пациентов с псУКР и 0,15±0,07 — в контрольной группе. При корреляционном анализе у пациентов с псУКР только степень изменения функции психического контроля показала отрицательную взаимосвязь с объемом поражения белого вещества. Полученные данные позволяют предположить, что оценка объема поражения белого вещества имеет значение у пациентов с псУКР, однако не полностью объясняет снижение когнитивных функций.
Cerebral small vessel disease (CSVD) — is a clinical and radiological phenomenon characteristic of older adults. Currently, the extent of white matter lesions (WML) in patients with moderate cognitive disorders remains uncertain. Also, the relationship of cognitive impairment with the volume of WML has not been suffi ciently studied. The aim of the study was to analyze the WML volumes in patients with subcortical vascular mild cognitive impairment (svMCI) and in the control group according to magnetic resonance imaging (MRI). The study included 50 people: 25 patients with svMCI (average age 75,88±4,04 years) and 25 conditionally healthy volunteers (average age 69,96±3,07 years). Signifi cant differences in the volume of WML between the study groups were obtained. The fraction of hypointense WML was 0,74±0,41 in patients with svMCI and 0,15±0,07 in the control group. In the correlation analysis in the svMCI group, only the function of mental control showed a negative relationship with the fraction of WML. The data obtained suggest that the assessment of the volume of WML is important in patients with svMCI, but does not fully explain the decline in cognitive functions.

Сахарный диабет 2-го типа (СД2) является одним из распространенных неинфекционных заболеваний в мире. Среди лиц с СД2 преобладают пациенты старшей возрастной группы — 60,5 % всех больных старше 65 лет, а пик распространенности приходится на возраст 65–69 лет. Лечение этой патологии у пациентов пожилого возраста имеет определенные особенности, что связано с высоким уровнем полиморбидности. Терапия СД2 должна быть направлена не только на компенсацию уровня гликемии, но и на лечение и профилактику осложнений СД, улучшение качества жизни больных. При выборе сахароснижающей терапии следует учитывать влияние препаратов на сердечно-сосудистую систему и функцию почек, а также риск гипогликемии, которая чаще встречается у лиц старшего возраста и влияет на когнитивную функцию таких пациентов. В данном обзоре рассмотрены возможности использования у больных пожилого и старческого возраста различных групп сахароснижающих препаратов.
Type 2 diabetes mellitus is one of the most common non-infectious diseases in the world. Among people with type 2 diabetes, patients of the older age group predominate: 60,5 % of all patients are over 65 years old, and the peak prevalence is at the age of 65–69 years. The treatment of this pathology in elderly patients has certain features, which is associated with a high level of polymorbidity in these patients. Therapy for type 2 diabetes should be aimed not only at compensating the level of glycemia, but also at treating and preventing complications of diabetes, and improving the quality of life of patients. The choice of hypoglycemic therapy should take into account the effect of drugs on the cardiovascular system and kidney function, as well as the risk of hypoglycemia, which is more common in older people and affects the cognitive function of such patients. This review discusses the possibilities of using various groups of antidiabetic drugs in elderly and old patients.

Kelet és Nyugat találkozása Hishida Shunsō Samantabhadra ábrázolásán
Authors: Kiss Mónika 
Published: May 2023

Hishida Shunsō 菱田春草 (1874–1911) a Meiji-kori nihonga festők egyik első generációjához tartozott. Ezt az „új” stílust, avagy műfajt a nyugati festészeti stílusok és technikák gyors terjedésével szemben a hagyományos japán festészetet megmentő irányzatként állították be. Bár a Shunsō művészete iránti érdeklődés az elmúlt néhány évtizedben folyamatosan nőtt Japánban, még mindig meglehetősen ismeretlen a nyugati kutatók körében, és ez különösen igaz a buddhista festményeire.A jelen tanulmányban egy ilyen buddhista témájú festményt vizsgálok meg. A festmény a Fugen Bosatsu (Samantabhadra Bodhisattva) címet viseli, és egy fiatal fiút ábrázol, aki egy elefánt tetején olvas. Maga a festmény nem közismert és a datálása is kérdéses, ezért bizonyítékokkal alátámasztva érvelek amellett, hogy 1903 előtt készült, amikor is a szintén nihonga festő és barát Yokoyama Taikannal 横山大観 (1868–1958) Indiába utazott, hogy felfedezze a kortárs indiai (vallásos) művészetet. Ez az utazás kétségkívül változást hozott a stílusában, főként, ami a buddhista témájú festményeit illeti. A tanulmány fő tézise, hogy a Fugen-festmény határvonalat jelent Shunsō vallásos festményeiben, és megállapítható, hogy stilisztikailag különbözik az indiai tartózkodás után készült festményeitől. Ezen buddhista istenség ábrázolásának számos hagyományos gyökere van, azonban itt egy ikonográfiai szempontból hibrid formával találkozunk, amelyben keverednek a zen festészetben általános Shaka-háromságok előzményei a kevésbé ismert és elterjedt Chigo Fugen (Samantabhadra fiatal fiúként ábrázolva) megjelenítésével. Shunsō szembeállította az elefánt realista ábrázolását a hagyományosan kivitelezett kontúros fiúképpel, ezért ez a festmény az egyik legjobb példa arra, hogy a nihongaművészek hogyan ötvözték keleti (jelen esetben japán) örökségüket a nyugati művészeti technikákkal és anyagokkal, amelyeket újonnan kerültek át Japánba a Meiji-korban.

Intacs and Topography-Guided Photorefractive Keratectomy for Treatment of Incomplete LASIK Flap-Induced Irregular Corneal Topography: A Case Report
Authors: Yu Austin S. , Hersh Peter S. , Gelles John D. , Greenstein Steven A. 
Published: May 2023

Purpose:
To report a case of irregular corneal astigmatism and decreased visual function secondary to excimer ablation over an incomplete laser in situ keratomileusis (LASIK) flap treated with Intacs (CorneaGen) implantation and topography-guided (TG-PRK) and wavefront-optimized (WF-PRK) photorefractive keratectomy.

Methods:
The patient underwent Intacs implantation, TG-PRK, and WF-PRK enhancement in the right eye, with 4 to 6 months between procedures. Principal outcomes included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, manifest refraction, topographic maximum keratometry, and inferior-superior value.

Results:
UDVA changed from 20/40 to 20/100 after Intacs implantation, but improved to 20/50 after TG-PRK and 20/25 at 4 months after WF-PRK. CDVA declined from 20/40 to 20/50 after Intacs implantation, but improved to 20/20 after TG-PRK and 20/15 after WF-PRK. Overall, maximum keratometry flattened from 53.20 to 47.00 diopters (D) and inferior-superior value improved from 11.60 to 2.40 D.

Conclusions:
This case illustrates the successful use of sequential Intacs implantation and TG-PRK after an irregular LASIK ablation to improve irregular astigmatism and loss of visual function.

Analysis of the potential reasons for repeated radiography: a study in a major hospital in south eastern Iran
Authors: Dahmarde Hamid , Abiri Marzieh , Sanei Sistani Sharareh 
Published: May 2023

Introduction
Rejecting, removing and repeating the process of taking diagnostic X-ray images could lead to professional and moral challenges in the case of radiologic imaging. The aim of this study was to investigate the reason for repetitive imaging and the types of images mostly repeated.
Methods
Radiographic images taken in this center in the first half of 1400 were evaluated. At the end of each week, repetitive images were referred to the researcher to analyze the frequency of repetitive radiographies and the causes.
Results
In this study, a total of 4916 radiographies taken in Ali Ibn-e-Abitibi Hospital during the first 6 months of the year 1400 were evaluated. Among 398 repetitive radiographies, 94 repetitions (23.62%) were due to inappropriate positioning, 92 repetitions (23.12%) were due to patient's movements, 56 repetitions (14.07%) were due to inadequate radiation, 51 repetitions (12.81%) were due to inadequate processing, 46 repetitions (11.56%) were due to inadequate preparation of the patient, and 59 repetitions(14.82 %) were due to other reasons
Conclusion
In this study, the rate of repetitive radiographies taken in Ali Ibn-e-Abi Talib Hospital was estimated as 8.10%, with the most common reason for repetitions being estimated inappropriate positioning. Considering the fact that repetitive radiography mostly depends on operator-related factors, it is recommended to repeat the study after educating staff in order to compare the rate and reason of repetition.

ABSTRACT. The azo ligand obtained from the diazotization reaction of 2-aminobenzothiazole and 4-nitroaniline yielded a novel series of complexes with Co(II), Ni(II), Cu(II), and Zn(II) ions. The complexes were investigated using spectral techniques such as UV-Vis, FT-IR, 1H and 13C NMR spectroscopic analyses, LC-MS and atomic absorption spectrometry, electrical conductivity, and magnetic susceptibility. The molar ratio of the synthesized compounds was determined using the ligand exchange ratio, which revealed the metal-ligand ratios in the isolated complexes were 1:2. The synthesized complexes were tested for antimicrobial activity against S. aureus, E. coli, C. albicans, and C. tropicalis bacterial species. Additionally, their binding affinities were predicted using molecular docking analysis, and their pharmacokinetic and drug-likeness properties were evaluated.

Published: May 2023

ABSTRACT. In this work, the Copper composites Cu-x wt. % B4C (x = 0, 5, 10, 15, 20) were fabricated for the metallurgical and mechanical property evaluation as per ASTM standards. The metallurgical characterization tests on the samples include x-ray diffraction, optical microscopy, and scanning electron microscopy with EDX. Further, pin-on-disc apparatus was used to investigate the tribological behavior of composite specimens. An SEM micrograph of the worn surface and wear debris, along with the Gwyddion software, has been used to discuss the wear mechanisms in detail. The Artificial Neural Networks (ANN) classifier model is also constructed to describe the wear behavior in more detail. The experimental results inferred that the addition of Boron carbide particles has enhanced the Copper's corrosion resistance in a 1 M HCl electrolyte solution from 30.34% to 74.2%, 75.08%, and 83.29% with B and C ions. Also, it significantly enhance the mechanical and tribological characteristics considerably.

ABSTRACT. In line with the global interest and demand in finding sustainable ways to the emerging antimicrobial and cytotoxic activities, our study highlights the unique chemical composition of G. barbadense stem. Petroleum ether extracts were analyzed via headspace-gas chromatography/mass spectrometry (HS-GC/MS) revealing 48 compounds, thirteen major and accounting for 56.29% of total peak areas. By using liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) identify 16 major phenolic compounds from the methanolic extract. Both petroleum ether and methanolic extracts were tested for antibacterial activity against four pathogenic bacterial strains (Escherichia coli ATCC10536, Staphylococcus aureus ATCC6538, Salmonella enterica ATCC 14028, and Pseudomonas aeruginosa ATCC 9027) by using disk diffusion method. The antifungal activity against two fungal strains (Aspergillus niger and Aspergillus fumigatus) was evaluated. The results were compared to the activity of ciprofloxacin as a stander. The in-vitro cytotoxic activity of the methanolic extract showed a potent effect against liver (HEPG2) with IC50 values (18.8±7.4 μg/mL) and moderate activity against colon (HCT116) and breast (MCF7) cancer.
