Published: May 2021

Barium silicates may be found in contact aureoles and are used in several important technologies (e.g., LEDs). The BaO-SiO2 system stabilizes 13 crystalline phases with different silicate tetrahedral and connectivity profiles. Aside from phases composed of a single structural unit (isolated or homo-connected tetrahedra), one encounters the relatively rare case of hetero-connected tetrahedra in which varying proportions of several Qn species are linked together. Here, we analyze the 29Si MAS NMR and Raman spectroscopic manifestations of the connectivities in seven barium silicates: Ba2SiO4, high-BaSiO3, Ba4Si6O16, Ba5Si8O21, Ba6Si10O26, high-BaSi2O5, and sanbornite (low-BaSi2O5). The structures and purity of these phases were confirmed by Rietveld refinement. From a Raman spectroscopic database of 144 predominantly homo-connected crystalline silicates, the mean Qn mode frequencies νQn (±1σ) are found at 828 (±14) cm−1 for Q0, 905 (±22) cm−1 for Q1, 994 (±26) cm−1 for Q2, and 1068 (±18) cm−1 for Q3 units. Experimentally, homo-connected barium silicates show good agreement with these values, whereas the hetero-connected phases show a wider range of νQ2 than of νQ3 frequencies. While the 29Si NMR chemical shifts of the barium silicates are in agreement with known structural trends, those measured for the Q2 resonances remain essentially constant, which may be caused by the lattice distortion around the large Ba2+ cations. To complement and rationalize experimental measurements, first-principles calculations at the density functional theory level have reproduced measured frequencies within a mean absolute deviation of <7 cm−1. Our work highlights how the results provided by 29Si NMR and Raman spectroscopies and ab initio calculations can be combined to rationalize the structure of complex systems. The present findings also shed light on the vibrational modes that may be used to track bond lengths in situ at extreme conditions and the behavior of homo- vs. hetero-connectivity, revealing clear implications for evaluating silicate glasses and melts where hetero-connectivity is the rule rather than the exception.

The results of the study showed that the average number of publications about both suture material with added properties and suture material in general in journals was low. At the same time, there was a decrease in the average number of publications on suture material with added properties for the period 2017-2019.
Microbiological analysis of domestic water sources in Banda slum of Kampala, Uganda
Authors: Isingoma Barugahara Evyline , Stephen Kwesiga
Published: May 2021

There is scarcity of information about the safety of water in Banda slum of Kampala, Uganda and yet reports indicate outbreaks of infectious diseases such as typhoid fever and cholera. The aim of this study was to determine the risk of exposure to waterborne infections by Banda residents due to faecal contamination of water sources. Four hundred respondents were sampled and interviewed on the methods of water collection, treatment and storage. Water samples were collected with sterile glass bottles in duplicate from the dug well, protected spring and piped water system in December 2018 on two different consecutive days. They were transported to the laboratory for total and faecal coliform count analysis within 2 h using a lightproof-insulated box containing ice-packs. The mean Escherichia coli count for the dug well was 43 ± 18 c.f.u/mL. The protected spring had no detectable E. coli, but its total plate count level was 76 ± 1.4 c.f.u/mL. Only 46% of the respondents treated their drinking water using boiling and filtering methods. Poor sanitation and hygiene practices were observed. The total and faecal coliform counts of water sources were unsatisfactory making Banda residents highly at risk of infectious diseases, given the small number of residents that treated water.

Published: May 2021

Objetivo: Proporcionar una visión general sobre el campo emergente de la ciencia de la implementación a los profesionales de salud en Latinoamérica. Materiales y Métodos: Revisión rápida de evidencias para definir la ciencia de la implementación, describir su estado, presentar los marcos conceptuales más citados en la literatura, y proveer recomendaciones para la educación en ciencias de la salud. Resultados: La ciencia de la implementación es una nueva, pero ampliamente reconocida, ciencia con una definición formal y teorías que la apoyan. Los dos marcos conceptuales más ampliamente citados en la literatura son el Promoting Action on Research Implementation in Health Services (PARiHS) y el Consolidated Framework for Implementation Research (CFIR). Sin embargo, se observa que ambos marcos conceptuales requieren una mejora continua para abordar los vínculos entre investigación y práctica. Específicamente, a medida que la ciencia se desarrolla, es necesario prestar más atención a la vinculación de las ciencias de descubrimiento, traducción e implementación en un enfoque de ciencia aplicada para transformar el conocimiento en evidencia comprensible para su uso inmediato en la práctica diaria. Conclusiones: La ciencia de la implementación tiene el potencial para acelerar el rol de la mejora de la calidad en el sector público de salud. La evidencia puede ser rápidamente incorporada en la práctica clínica con la presencia de profesionales de salud preparados para este rol emergente. De igual forma, los programas de ciencias de la salud en las Universidades de Latinoamérica necesitan empezar a explorar la utilidad de desarrollar grados académicos doctorales de práctica para apoyar la mejora del sistema de salud a través de la ciencia de la implementación.

Published: May 2021

Background:

Plants that are rich in triterpenoid compounds possess various biological
activities and are reported in many scientific works. Triterpenoids, because of their broad sources,
wide variety, high medicinal value, and anti-tumor properties, have drawn great attention from scientists.
However, the lack of approach to understand the link between their chemical structures and
biological activities has limited the fundamental comprehension of these compounds in cancer therapy.

Objective:

The aim of the study is to summarize the list of plants with triterpenoids and their derivatives
that are a source of potential novel therapeutic anti-cancer agents by interpreting the network
of anti-cancer activity and the structures of triterpenoids and their derivatives.

Methods:

This work focuses on analyzing relevant patents and references that detail the structure
of triterpenoids and their derivatives for the treatment of tumors.

Result:

Pentacyclic triterpenoid plays a more important role in improving the autophagic signaling
pathways of cancer cells compared to tetracyclic triterpenoid.

Conclusion:

The heterogenous skeleton structure of triterpenoids impairs programmed cell death
signaling pathways in various cancers.

FORMS OF ENVIRONMENTAL RIGHT PROTECTION
Authors:   N.Sh. Gadzhialieva Dagestan State University, Gadzhialieva N.Sh.
Published: May 2021

The article analyzes various forms of protecting the right to a favorable environment, examines the concept of a form of protecting rights as a legal category. Based on the analysis of regulatory and scientific sources, the author has classified the forms of protection of the right to a favorable environment provided for in the law. Depending on the endowment of the subject carrying out the defense with the authority to use state coercion, the author identifies two large independent forms of protection: state and non-state. The author notes the legal uncertainty regarding the content of the right to a healthy environment, which complicates its protection. The positions of scientists who consider the right to a favorable environment in a narrow and broad sense are analyzed. Attention is drawn to the fact that the mechanism for protecting the right and the content of the right to a favorable environment are in organic unity and thus in the aggregate affect the formation of forms and methods of protecting the right to a favorable environment by a person. In conclusion, the author formulates the conclusions of the study, relying not only on the current legislation of the Russian Federation, but also on the established judicial practice, as well as on the scientific dogmas of Russian scientists in the field under study.
TO THE QUESTION OF THE APPROPRIATENESS OF TRANSFERRING WORKING PRISONERS TO STRICT CONDITIONS OF SERVING THEIR SENTENCES
Authors:   I.N. Barmashov Institute of the Academy of the FPS of Russia, Barmashov I.N.
Published: May 2021

In the article analyses one of the reasons leading to a decrease in the level of employment of prisoners for deprivation of liberty, associated with their transfer to strict conditions of serving a sentence, and the inability to take off work due to the lack of separate premises equipped with jobs in correctional institutions. It is explained that prisoners transferred to strict conditions of serving a sentence must work separately from other prisoners, which is enshrined in the current rules of internal regulations of correctional institutions, but is not reflected in the Penal Enforcement Code of the Russian Federation. To remedy the situation, it is proposed to introduce into the Penal Enforcement Code of the Russian Federation a norm providing for the work of prisoners transferred to strict conditions of serving a sentence, separate from other prisoners, and a provision allowing the transfer of working prisoners to strict conditions of serving a sentence only if there are separate working premises in correctional institutions.
SPECIFICS OF THE TREATMENT OF MARITAL AND FAMILY RELATIONS IN PAROLE: LEGISLATIVE IMPROVEMENT
Authors:   A.V. Sokolova Vladimir law Institute of the Federal penitentiary service (VUI of the Federal penitentiary service of Russia), Sokolova A.V.
Published: May 2021

The article is devoted to considering the specifics of taking into account marriage and family relations when considering the advisability of applying the institution of parole from serving a sentence in domestic and foreign criminal law. The article analyses the norms of foreign legislation governing issues of parole from serving a sentence, as well as a study of domestic criminal legislation and law enforcement practice on issues of parole. This analysis concluded that there are certain problems in the legal regulation of parole from serving a sentence, and judicial practice often demonstrates different approaches to solving tasks. In addition, the analysis made it possible for the author to argue that the courts practically do not impose obligations on the convicted person related to his marital and family relations. The author proposed changes to Part 2 of Art. 79 of the Criminal Code, according to which the courts, when applying parole, will be required to impose obligations on the convicted person. Among such duties, the author refers to the fulfillment of parental duties, obligations to care for elderly parents, as well as the obligation to provide material assistance to the family, to participate in the upbringing of a young child or to provide assistance (both material and other) to elderly parents if the convict does not take part in the life of loved ones.

Published: May 2021

O estudo trata da história local e educativa de Bom Jesus, cidade nordestina do interior piauiense. O objetivo foi compreender, a partir da contextualização histórica, a história da educação de Bom Jesus, mediante pesquisa qualitativa do tipo histórica. Os resultados inferem que essa região, em seus primórdios, teve a sua história e constituição educativa estritamente ligada à atividade de grupos religiosos, que ali chegaram e, ao construir uma capela, instigaram o desenvolvimento populacional e educativo. Especificamente no que toca o campo educacional, averiguou-se que, em face do descompromisso público com essa matéria, os religiosos foram os responsáveis por iniciar a escolarização formal, tendo firmado parceria, em alguns momentos, com o governo estadual, sendo a década de 1970 a mais exitosa, pois foi marcada pela fundação das primeiras escolas de variados níveis. Conclui-se que a reconstituição histórica educacional de Bom Jesus, além de ensejar maior conhecimento sobre o processo de expansão da escola, permite desvelar aspectos macrossociais dessa cidade e, por conseguinte, do Piauí e do Nordeste brasileiro.

The development of a surrogate soil to assist the revegetation and stabilisation of metal-mine tailings
Authors:   , De-Quincey Heather
Published: May 2021

Abandoned mines are considered among the most severe of environmental issues, and are a significant danger to environmental, animal, and human health (Mehta et al., 2020). To date, ~ 600,000 abandoned mines exist, the costly reclamation of which often falls to publicly funded bodies (Archer & Caldwell, 2004; Mayes et al., 2009). Traditional reclamation methods are financially unattainable at ~ £50 million per large mine (McKenna, 2002), and an alternative, lower-cost method is required (Garcia, 2008). One contemporary reclamation method found to be effective is that of capping mine waste with a soil cover (O’Kane & Ayres, 2012). In this research, an adhesive surrogate soil capping layer for the hydraulic application to steep-sided metal-mine tailings was developed at the cost of ~ £6 .m-² (at the time of writing). The surrogate soil was refined throughout a series of trials. A rainfall trial was conducted to develop an adhesive and erosion resistant soil material. A germination trial (N = 500) determined the soil materials which best assisted rapid plant establishment. The successful results of these laboratory-based trials guided a nine-month field trial on an abandoned Pb mine, Nantymwyn (UK) (N = 154). The field trial concluded that the surrogate soils effectively resisted erosion and supported the early (seven month) growth of metal-tolerant grass species. The grasses contained Pb, Zn, Cd and Cu concentrations at < 1% of the phytotoxic threshold. However, seasonal climatic events and a negative water balance ultimately led to complete grass mortality after nine months. Tailings bank destabilisation also influenced grass survival. The research revealed that the soil’s available water supply was of greater impact to plant survival than metal toxicity. The results indicated that should the soils water-holding capacity be improved, the application of a carefully designed surrogate soil has the potential to support vegetative cover on steep, bare metal-mine tailings.

Introduction: SLAP injuries are common in young athletes and in the military men. In the failure of conservative treatment, surgical treatment is indicated. Objectives: To compare clinical results in two groups of sportsmen and military men with SLAP type II injuries who underwent two surgical techniques. Material and methods: Retrospective study, in sportsmen and military personnel submitted to surgical treatment between 2010 and 2018. Each group was submitted to the same technique by the same surgical team. Clinical evaluation was performed with a Constant (SC) score, complications were recorded, surgical re-interventions, rate of return to sports activity and rate of return to the previous level of activity. Results: We analyzed 25 patients, 12 who underwent labral repair (RL) and 13 who underwent bicipital tendon tenodesis (TLPB). The mean follow-up was 4.5 years, the mean age was 25.7 years for the RL group and 31 years for the TLPB group. There was an improvement in SC in both groups. In the RL, there were 4 cases of post-operative stiffness with two re-interventions, whereas with the TLPB there was a failure with tenodesis rupture. The rate of return to sports activity was 100% in both groups, but in the RL group the rate of return to the previous level was 42% and in the TLPB group 70%. Conclusions: Both techniques have good clinical results in the medium and long term. In our series, the results are superior for TLPB and without re-interventions. In the RL group, the rate of complications was higher and the rate of return to the previous level of sports activity was lower.
Resolution of Laryngeal Oedema in a Patient with Acquired C1-Inhibitor Deficiency. A Case Report
Authors: Bara Noémi-Anna , Nadasan Valentin
Published: May 2021

Introduction

Laryngeal oedema caused by acquired angioedema due to C1-inhibitor deficiency (C1-INH-AAE) is a life-threatening condition. The swelling is bradykinin mediated and will not respond to the usual treatment with antihistamines, corticosteroids, or epinephrine. Instead, kallikrein-bradykinin-targeted therapies should be used promptly to prevent asphyxiation.

Case presentation

A 43 years old female presented at the Hereditary Angioedema Centre reporting a one-year history of peripheral, facial, and neck oedema. Treatment with antihistamines and corticosteroids had been ineffective. Laboratory results showed complement level deficiencies and monoclonal gammopathy characterised as immunoglobulin M. An abdominal ultrasound revealed splenomegaly. A bone marrow biopsy was normal. Based on these data, the diagnosis of C1-INH-AAE associated with monoclonal gammopathy of uncertain significance (MGUS) was made. As C1-INH-AAE can present with life-threatening, standard treatment-resistant laryngeal oedema, an emergency care treatment plan was proposed, and the patient was advised to present to the emergency department (ED) with this medical letter. Based on these recommendations, three laryngeal attacks were successfully treated in the ED with recombinant human C1-inhibitor (two attacks) and fresh frozen plasma (one attack). After these episodes, the patient was prescribed prophylactic treatment with antifibrinolytics. No further angioedema attacks were reported by the patient at the 18 months follow-up visit.

Conclusions

Because angioedema of the upper airways is a life-threatening condition, recognising the specific type of swelling by the emergency physician is critical in providing immediate and effective treatment to reduce the associated risk of asphyxiation. C1-INH-AAE being a rare disorder, patients should have available an emergency care treatment plan with recommendations of acute treatment possibilities.

Background

Recent studies have reported that COVID-19 infected patients with stroke, who were often in the older age group, had a higher incidence of vascular risk factors, and more severe infection related respiratory symptoms. These observations provided little evidence to suggest that COVID-19 infection is a potential causative factor for stroke. This report describes a young patient with a cerebellar stroke secondary to COVID-19 infection.

Case presentation

A 45-year old male presented at a hospital, reporting a two-day history of headache, vertigo, persistent vomiting, and unsteady gait. Physical examination revealed gaze-evoked nystagmus on extraocular movement testing, left-sided dysmetria and dysdiadochokinesia. He was diagnosed with a left cerebellar stroke. An external ventricular drain was inserted, and sub-occipital craniectomy was performed to manage the effects of elevated intracranial pressure due to the extent of oedema secondary to the infarct. He also underwent screening for the COVID-19 infection, which was positive on SARS-COV-2 polymerase chain reaction testing of his endotracheal aspirate. Blood and cerebrospinal fluid samples were negative. After the surgery, the patient developed atrial fibrillation and had prolonged vomiting symptoms, but these resolved eventually with symptomatic treatment. He was started on aspirin and statin therapy, but anticoagulation was withheld due to bleeding concerns. The external ventricular drain was removed nine days after the surgery. He continued with active rehabilitation.

Conclusions

Young patients with COVID-19 infection may be more susceptible to stroke, even in the absence of risk factors. Standard treatment with aspirin and statins remains essential in the management of COVID-19 related stroke. Anticoagulation for secondary prevention in those with atrial fibrillation should not be routine and has to be carefully evaluated for its benefits compared to the potential harms of increased bleeding associated with COVID-19 infection.

Published: May 2021

Purpose. To study morphological changes in the cornea by confocal microscopy of simultaneous MyoRing implantation with corneal crosslinking in patients with keratoconus. Material and methods. The clinical study included 15 patients (16 eyes) with progressive keratoconus. All patients underwent a combination treatment: implantation of MyoRing intrastromal corneal rings (Dioptex GmBH, Linz, Austria) in combination with corneal crosslinking. The number of cells and quality indicators in each layer of the cornea were compared before and during 36 months after surgery. Results. Qualitative analysis of the cornea showed transient disturbances of the subepithelial nerve plexus, an increase in the reflectivity of stromal keratocytes, and moderate fibroplasia in the middle parts of the stroma in the area of the intrastromal pocket. During the follow-up period of 12 months or more after surgery, no significant changes in the corneal ultrastructure were detected in the dynamics. There was no significant decrease in endothelial cell density in the postoperative period. Conclusion. Analysis of morphological changes confirms the safety of a combination of simultaneous implantation of the MyoRing intrastromal ring and corneal crosslinking in stage II-III keratoconus by confocal microscopy and allows dynamic observation of changes in the corneal structure during intrastromal surgery. Key words: keratoconus, confocal microscopy, intrastromal corneal rings, MyoRing, corneal crosslinking.

Published: May 2021

Purpose. Is to propose a marking of a toric intraocular lens (TIOL) to accurately determine its position in the capsular bag during surgery in patients with corneal astigmatism in a narrow rigid pupil. Material and methods. The study included 19 patients (24 eyes) with corneal astigmatism from 1.25 to 5.0 diopters. The maximum observation period for patients after surgery is 6 months. Results. The mean uncorrected visual acuity (UVA) after surgery was 0.6±0.21. The spherical postoperative component of refraction was 0.09±0.81, the cylindrical component was 0.25±0.52 diopters. During the entire observation period after surgery, stable refraction and visual functions were noted. Conclusion. The proposed improved lens marking technique makes it possible to accurately determine the position of the cylindrical component of the THIOL, ensuring the correct position of the lens under conditions of a narrow rigid pupil. Key words: cataract phacoemulsification, astigmatism, toric intraocular lenses, marking.

Purpose. To investigate the dynamics of morphological changes in the rat cornea after its ultraviolet cross-linking using various photosensitizer solutions. Material and methods. Studies were conducted on 20 rats in three groups. In the first group, 0.1% Riboflavin solution was used for saturation, in the second – 0.1% Riboflavin and 20% dextran; the third – intact (control). A UV cross-linking model (370 nm, 3 mW/cm2, 10 min) with corneal deepithelization with a diameter of 3 mm was used. Histomaterial processing was performed according to the standard procedure on the 3rd, 7th, and 30th days after surgery. Histological sections 1-4 microns thick were prepared on a rotary microtome RM 2145 (Leica Microsystems, Germany), stained with hematoxylin-eosin and using the van Gieson method. Light microscopy was performed using a LEICA DM 2500 microscope with a Leica DFC 450 digital camera (Leica Microsystems, Germany). Results. The main morphological changes in the rat cornea after UV cross-linking with 0.1% Riboflavin solution were associated with loosening of bundles of collagen fibers. This was caused by the development of stroma edema in the early postoperative period (3-7 days), which persisted up to 30 days of the experiment. A morphological feature of the use of Dextralink solution in corneal cross-linking is less pronounced stroma disfoliation, which is associated with the dehydrating effect of dextran. In both groups, a decrease in the density of stroma keratocytes was found. Key words: cornea, ultraviolet corneal cross-linking, corneal morphology.

Currently no unified generally accepted classification of intraocular changes due to diabetes mellitus (DM), in particular, diabetic retinopathy (DR). The methodological heterogeneity of the existing classifications is largely due to the different directions of their application. Some classifications are optimal for the choice of surgical treatment tactics, others - for laser and / or combined interventions. Obviously, the valuation of any classification lies in the completeness whole palette of available clinical and morphological changes considering staging pathogenetic process. Therefore, the search for optimal classification of DR that meets current possibilities of treating vitreoretinal pathology is the subject of a lively discussion. Key words: classifications, diabetic retinopathy, advantages and limitations.
