Abstract
A new species from the family Tylenchidae was recovered in the grasslands of Isfahan province, Iran, and is herein described based on morphological and molecular data. Ottolenchus isfahanicus n. sp. is mainly characterized by having a faintly annulated cuticle; elongated, slightly sigmoid amphidial apertures developed metacorpus with distinct valve under LM; vulva located at 69.472.3% of body length; large spermatheca about 2.75 times of corresponding body width; and elongated conoid tail with broadly rounded tip. SEM observations showed that the lip region is smooth; the amphidial apertures are elongated, slightly sigmoid slits; and the lateral field is a simple band. It is further characterized by 477-to-515-μm-long females with delicate 5.7-to-6.9-μm-long stylets with small, slightly posteriorly sloping knobs, as well as functional males, in the population. The new species closely resembles O. facultativus, but is separated from it based on morphological and molecular data. It was further morphologically compared with O. discrepans, O. fungivorus, and O. sinipersici. The phylogenetic relationships of the new species with other relevant genera and species were reconstructed using near-full-length sequences of small subunit and D2-D3 expansion segments of large subunit (SSU and LSU D2-D3). In the inferred SSU phylogeny, the newly generated sequence of Ottolenchus isfahanicus n. sp. formed a clade with two sequences of O. sinipersici and sequences assigned to O. facultativus and O. fungivorus. In the inferred LSU phylogeny, the three newly generated sequences of the new species and LSU sequences of O. sinipersici and O. discrepans formed a clade.

Authors: Mc Donnell Rory J. , K. Howe Dana , R. Denver Dee 
Published: April 2023

Abstract

Phasmarhabditis californica, a commercially available biological control agent in England, Scotland, and Wales (Nemaslug 2.0 ®), was discovered for the first time in Washington State during 2022. Nematodes were recovered from the invasive gastropods Arion hortensis, Deroceras reticulatum, and Oxychilus sp. in garden centers in both Vancouver and Spokane. The 18S ribosomal RNA gene was used to identify the nematodes. This discovery builds upon previous reports of P. californica in California and Oregon and suggests that the species is widespread throughout the west coast of the U.S. Future research directions with P. californica are proposed.
How are polychlorinated biphenyls currently being produced, despite the production ban, and do they pose a risk to the environment?
Authors: Gabryszewska Marta 
Published: April 2023

Abstract
Polychlorinated biphenyls (PCBs) are a group consisting of 209 congeners, differing in the number and site of substitution of chlorine atoms to the biphenyl molecule. Due to their physicochemical properties, they have found wide industry use. As a result of many years of large-scale use of PCBs, their toxic properties began to be noticed as they manifested in poisoning among humans. After thorough testing of PCBs, they were classified in the group of persistent organic pollutants (POPs), and their production was banned and they were withdrawn from use. Although PCBs are no longer produced in factories, they can still be formed. In this article, will be presented and explained methods of accidental formation of PCBs. Based on data from the literature, we performed an environmental risk assessment for PCB-contaminated soils.
Design of Mine Warfare Diving Technology. Standardisation Requirements
Authors: Kłos Ryszard 
Published: April 2023

Abstract
This article is consecutive in an unintended series on diving technology design [1,2]. Requests for a detailed account of the strategy
1 employed and its compatibility with methodology2 suggest that the earlier description of it proved too general [3]. In the first part, on the example of diving technology used in mine warfare systems, its design is briefly discussed in the light of meeting NATO Standardisation Organisation requirements. The article refers to the elements of the methodology3 applied in the work on the Nx-SCR CRABE SCUBA diving technology on the basis of the national theory4 containing primarily deterministic methods5 for modelling semi-closed SCR breathing systems6, enabling reliable research with previously unavailable efficiency [4,5].
VIS camera studies of the combustion process of pyrotechnic retarders of NGP-76 underwater fifle grenades
Authors: Miszczak M. , Warchoł R. , Gędziorowski M.P. , Piecuch M. , Grzeczka G. 
Published: April 2023

Abstract
The study presents the combustion process of the multi-segment, low-gas pyrotechnic column of the warhead retarder of the NGP-76 underwater rifle grenade, designed to combat divers with an underwater shock wave. The combustion process, i.e. process from the ignition of the first segment of the retarder to the completion of combustion of its last segment, was recorded with a VIS camera filming at 30 frames per second. The rapid, short combustion of these outermost segments containing zirconium and Pb3O4 (minium) was accompanied by a blinding plume of brightly glowing particles of zirconium dioxide and lead vapor. The combustion of the middle segments formed from the MGS-54 pyrotechnic mixture containing BaCrO4, KClO4 and Sb2S5, determining the duration of the delay, i.e. the delay produced by the retarder, was much slower and longer than that of the outermost segments. During the combustion of each MGS-54 segment, the combustion front took the form of a flat section in the initial part of the segment, i.e. in the area of higher density, while in the further part of the segment (with lower density) the shape of the front became irregular. At the MGS-54 segment boundary, the combustion front halted briefly. Behind the combustion front, a conical tail of luminous solid combustion products became clearly visible at the MGS-54 segment boundary. The gaseous combustion products of the MGS-54 segments, formed in small amounts and revealed as white plumes, were probably KCl vapor and/or sulfur dioxide. After combustion, the retarder column of the MGS-54 segments was green in color due to the presence of chromium compounds, possibly Ba(CrO2)2.

Research on saturation diving in Poland and its implementation. Part I B. General characteristics of saturation diving research in our Poland. Pioneer times; 1967-1985
Authors: Skrzyński Stanisław 
Published: April 2023

Abstract
The article is the first in a series of articles on the research and implementation of saturation diving technology in our country which presents the specific Polish conditions and achievements against the background of economic and historical circumstances. In view of the fact that research and implementation has a history of more than half a century, selected key figures of this period are recalled, some of whom have disappeared in the fogs of history. In the specialized literature of the world, the Polish underwater habitats of Meduza are among top 6 countries that researched and implemented, this high technology of saturation diving. Regarded as the inspirer, pioneer and creator of the first saturation diving, he designed and developed the technique and decompression with the cooperation of a team of enthusiasts from clubs and professional divers, as well as engineering staff from the Tri-City enterprises. In the first part of the article the author characterizes the saturation dives in comparison with short dives with particular emphasis on decompression, which is the key to safe diving. The article also takes into account the technical conditions for the implementation of the first saturation dives. The author discusses the general methodology of validation and verification of the assumed decompression, referring to the Polish conditions. He describes how the medical, technical, and organizational problems of implementation of saturation diving were solved in the pioneering period against the background of world achievements. Furthermore, the author describes Polish habitat constructions of Meduza and Geonur types and their application to underwater work on the Polish shelf and coastal areas. Despite the great progress in the field of medicine and technology, as well as organization, the problems of saturation diving, despite the passage of time, remain relevant, as these are the most difficult dives from the point of view of organization, underwater physiology and safety technology.

Published: April 2023

Abstract

Background
Deregulation of the apoptotic process underlies the pathogenesis of many cancers, including leukemia, but is also very important for the success of chemotherapy treatment. Therefore, the gene expression profile of main apoptotic factors, such as anti-apoptotic BCL2 (B-cell lymphoma protein 2) and pro-apoptotic BAX (BCL2-associated X), as well as genes involved in the multi-drug resistance (ABCB1), could have significant impact on the prognosis and could be used as targets for specific therapy.

Patients and methods
We analyzed the expression of BCL2, BAX, and ABCB1 in bone-marrow samples collected at diagnosis from 51 adult patients with acute myeloid leukemia with normal karyotype (AML-NK) using real-time polymerase chain reaction method, and examined their prognostic potential.

Results
Increased expression of BCL2 (BCL2
+) was associated with the presence of chemoresistance (p = 0.024), while patients with low BAX expression were more prone to relapse (p = 0.047). Analysis of the combined effect of BCL2 and BAX expression showed that 87% of patients with BAX/BCL2
low status were resistant to therapy (p = 0.044). High expression of ABCB1 was associated with BCL2
+ status (p < 0.001), and with absence FLT3-ITD mutations (p = 0.019).

Conclusions
The present analysis of BCL2, BAX, and ABCB1 gene expression profiles is the first study focusing solely on AML-NK patients. Preliminary results showed that patients with high BCL2 expression are likely to experience resistance to chemotherapy, and may benefit from specific anti-BCL2 treatment. Further investigations conducted on a larger number of patients could elucidate actual prognostic significance of these genes in AML-NK patients.

Abstract

Background
The relationship between interstitial lung abnormalities (ILAs) and the outcomes of lung cancer radiotherapy is unclear. This study investigated whether specific ILA subtypes are risk factors for radiation pneumonitis (RP).

Patients and methods
This retrospective study analysed patients with non-small cell lung cancer treated with radical-intent or salvage radiotherapy. Patients were categorised into normal (no abnormalities), ILA, and interstitial lung disease (ILD) groups. The ILA group was further subclassified into non-subpleural (NS), subpleural non-fibrotic (SNF), and subpleural fibrotic (SF) types. The Kaplan–Meier and Cox regression methods were used to determine RP and survival rates and compare these outcomes between groups, respectively.

Results
Overall, 175 patients (normal, n = 105; ILA-NS, n = 5; ILA-SNF, n = 28; ILA-SF, n = 31; ILD, n = 6) were enrolled. Grade ≥2 RP was observed in 71 (41%) patients. ILAs (hazard ratio [HR]: 2.33, p = 0.008), intensity-modulated radiotherapy (HR: 0.38, p = 0.03), and lung volume receiving 20 Gy (HR: 54.8, p = 0.03) contributed to the cumulative incidence of RP. Eight patients with grade 5 RP were in the ILA group, seven of whom had ILA-SF. Among radically treated patients, the ILA group had worse 2-year overall survival (OS) than the normal group (35.3% vs 54.6%, p = 0.005). Multivariate analysis revealed that the ILA-SF group contributed to poor OS (HR: 3.07, p =0.02).

Conclusions
ILAs, particularly ILA-SF, may be important risk factors for RP, which can worsen prognosis. These findings may aid in making decisions regarding radiotherapy.
Clear aligner therapy in contemporary orthodontics: A scoping review of scholarly literature
Authors: Adel Samar M. , Hansa Ismaeel , Vaid Nikhilesh R. 
Published: April 2023

Objectives:
Over the last two decades, clear aligners have become a mainstay in contemporary orthodontic practice primarily due to improvements in digital and 3D printing technologies, a growing interest in esthetic orthodontics, especially in the adult population, and aggressive manufacturer marketing internationally.

Material and Methods:
PubMed, Google Scholar, Cochrane Library, and EMBASE databases were searched from January 1998 to November 2021. The search terms used were “Invisalign” OR “clear aligner.” A total of 7000 records were searched, of which 369 potentially relevant articles were retrieved in full. 190 studies met the selection criteria following screening and were included in the scoping review.

Results:
This review scopes and analyses published orthodontic literature about CA according to a year-wise distribution into 3 groups, 2001–2010/2011–2020/2021. Most of the studies were published in the period between 2011 and 2020, with 138 studies accounting for 73%. The year 2021 followed, with 31 studies accounting for 16%, which was greater than the number of studies published in 10 years from 2001 to 2010. Studies were also classified based on the study designs with most of the published studies representing the lowest level of evidence including case reports, case series, narrative reviews, expert opinions, and editorials accounting for 137 studies, whereas case-control studies were the least reported studies with only 4 studies reported in the literature. In addition, they were categorized into seven main domains: (1) Biological considerations associated with clear aligner therapy (CAT), (2) Treatment outcomes considerations associated with CAT, (3) Geometrical considerations associated with CAT (clinical), (4) Biomechanical considerations associated with CAT (Laboratory/Finite element analysis), (5) Biomaterial considerations associated with CAT, (6) Patient education and experience and aesthetic and social perception of CAT, and (7) Miscellaneous. Treatment outcome considerations associated with CAT had the greatest percentage representing 36% of the total published domains, while the final place was occupied by the biomechanical considerations associated with CAT accounting for only 4% of the published domains about CAT.

Conclusion:
Treatment outcome was the domain most commonly reported by studies accounting for (36%). Most of the published studies are at the lowest level of evidence including case reports, case series, narrative reviews, and expert opinions. The vast majority of studies utilized only a single clear aligner brand. There is a greater need for research that studies CAT from a holistic perspective.
Analysis of the Physical, Chemical and Mineralogical Properties of Gallstones in the Antalya Province of Turkey
Authors: YALCIN Mustafa Gurhan 
Published: April 2023

The aim of the study is to determine chemical and physical properties of gallstones of Antalya province. In line with this, the chemical and mineralogical characteristics of 1243 gallstone samples from 69 patients were analyzed, using scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) analysis.
Cholesterol, carbonate apatite, calcium carbonate, calcium phosphate carbonate, calcium bilirubinate, and protein contents were observed. Cholesterol was detected in 95% of 69 samples patients, 44 of which were obtained from female patients. X-Ray Diffractometer (XRD) analysis showed newberyite, struvite, and aragonite minerals were found in the gallstones. Newberyite was present in 59% of the samples.
Newberyite precipitates in cases where the pH value of the patient’s bile decreases and where the amount of magnesium in the bile is high. Failure in the degradation magnesium during metabolism may lead to the formation of newberyite in gallstones. Struvite is associated with the presence of ammonium phosphate in bile. Ammonium phosphate is present in plant fertilizers and can easily be dissolved in water. These minerals (newberyite and struvite) are present in the human body and, more importantly, are intricately involved in the body’s production and destruction mechanisms. Therefore, determining the source of these minerals is crucial for understanding the mechanisms of gallstone formation.
On the dynamic effects of the motion of the center of mass of a rotating solid bodies in the central field
Authors: Оникийчук Валерий Николаевич , Оникийчук Игорь Валерьевич 
Published: April 2023

Предлагается модель движения твердого вращающегося тела в центральном гравитационном поле, которая учитывает массово-геометрические характеристики тела и фактор вращения тела относительно собственного центра масс. Осью вращения тела (относительно центра масс) является линия, соединяющая центр масс тела и центр инерциальной системы координат (центр гравитационного поля). Расстояние от центра масс тела до начала инерциальной системы является постоянным в процессе движения. В этом случае математической моделью движения являются динамические уравнения Эйлера для твердого тела с неподвижной точкой (классический «случай Эйлера- Пуансо»), Уравнения Эйлера-Пуансо представлены в проекции на инерциальные оси, на нормальные оси, а также в классическом виде - в проекции на оси, связанные с телом. Установлено, что при «малой» угловой скорости вращения относительно центра масс движение тела с высокой степенью точности совпадает с классической моделью движения точечной массы в центральном поле. В случае «большой» угловой скорости собственного вращения наблюдаются качественно новые динамические эффекты в движении тела. Так, например, изменяется ориентация вектора кинетического момента в инерциальном пространстве с соответствующим разворотом плоскости орбиты. При этом траектория движения выходит из классической плоскости орбиты и способна переходить в «спираль» и даже приобретать форму «орбитальной воронки». Новые нелинейные эффекты существенно усиливаются с ростом величины начальной угловой скорости вращения тела относительно собственного центра масс.
A model of motion of a solid rotating body in a central gravitational field is proposed, which takes into account the mass-geometric characteristics of the body and the factor of rotation of the body relative to its own center of mass. The axis of rotation of the body (relative to the center of mass) is the line connecting the center of mass of the body and the center of the inertial coordinate system (the center of the gravitational field). The distance from the center of mass of the body to the beginning of the inertial system is constant during movement. In this case, the mathematical model of motion is Euler's dynamic equations for a rigid body with a fixed point (the classic "Euler-Poinsot case"). The Euler-Poinsot equations are presented in projection on inertial axes, on normal axes, and also in classical form - in projection on axes connected with a body. It is established that at a "small" angular velocity of rotation relative to the center of mass, the motion of a body with a high degree of accuracy coincides with the classical model of the motion of a point mass in the central.
On decidability of finite subsets’ theory for dense linear order
Authors: Авхимович Николь Вадимовна , Дудаков Сергей Михайлович 
Published: April 2023

В работе рассматриваются алгебраические системы, где в качестве носителя выступают конечные подмножества некоторой безатомной булевой алгебры. Для полученной системы мы вводим новое отношение для конечных подмножеств: считаем, что одно подмножество состоит в отношении с другим подмножеством в том и только том случае, когда все элементы одного подмножества меньше всех элементов другого. Мы демонстрируем, что теория построенной таким образом новой системы сводится к теории безатомных булевых алгебр. Следовательно, также как и теория исходной системы, теория новой системы оказывается разрешимой.
We consider atomless boolean algebras, and study algebraic structures where the universe consists of finite subsets of such an algebra. On these structures, we define the new relation between finite subsets: we say that one set is less than another one iff all elements of the first set are less than all elements of the second one. We show that the theory of constructed structure is reducible to the theory of original boolean algebra. Hence, the theory of constructed structure is decidable.
On construction of exact solutions of stationary quasi-hydrodynamic system using Lin's substitution
Authors: Шеретов Юрий Владимирович 
Published: April 2023

Описаны новые точные решения стационарной квазигидродинамической (КГД) системы, которые не удовлетворяют ни уравнениям Навье-Стокса, ни уравнениям Эйлера. С помощью подстановки Линя указанная КГД система свелась к системе обыкновенных дифференциальных уравнений, которая была до конца проинтегрирована. При $c_s\to +\infty$, где $c_s$ - скорость звука в жидкости, построенные решения стремятся к соответствующим точным решениям системы Навье-Стокса.
New exact solutions of stationary quasi-hydrodynamic (QHD) system that do not satisfy either the Navier–Stokes equations or the Euler equations are described. With the help of Lin's substitution, the indicated QHD system was reduced to the system of ordinary differential equations, which was fully integrated. For $c_s\to +\infty$, where $c_s$ is the sound velocity in the liquid, the constructed solutions tend to the corresponding exact solutions of the Navier-Stokes system.
