Background: Urethroplasty is the surgical repair of an injury or defect within the walls of the urethra. Trauma, iatrogenic injury and infections are the most common causes of urethral injury/defect requiring repair. Urethroplasty is regarded as the go treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies. It is probably the only useful modality of treatment for long and complex strictures though recurrence rates are higher for this difficult treatment group. Case: 32 years old male came to surgery opd with complaint of swelling over base of penile shaft since 6 months associated with dribbling of urine since 6 months, painful erection, burning micturition since 1week Patient had history of trauma 6 months back during intercourse following which he had swelling over penis and transient hematuria. For which he went to a local doctor and took symptomatic treatment. The swelling and dribbling persisted but did not seek any medical attention. On clinical examination 3x2cm swelling over ventral aspect at the base of penis at penoscrotal junction with Skin over the swelling appears normal and on palpation swelling was non tender, no local rise in temperature, no redness, no discharge, non-translucent Bilateral testis palpable in scrotum On Ultrasonography swelling s/o partial tear of corpora spongiosum at the root of penis on ventral aspect communicating with urethra with approximately 15 cc collection with internal echoes in it f/s/o fracture penis. Patient underwent urethroplasty with local flap repair using buckÂ’s fascia. Conclusion: Urethroplasty with local flap repair using buckÂ’s fascia also be considered in treatment of urethral injury .

The COLOMBOMA EYE which means a lash less eye becomes one of the striking features of a rare disorder called TREACHER COLLINS SYNDROME. It may be a condition that affects the development of facial bonesand other tissues of the face. This condition features a wide range of signs and symptoms,from hardly perceptible to severe. Treacher Collins syndrome also called as Franceschettisyndrome is an autosomal dominant disorder of craniofacial development with variableexpressivity. Its named after E Treacher Collins who described the essential components ofthe condition in 1900. It is caused by the mutation of particular gene of which 81-90% of cause will be due to the mutation of TCOF1 gene. Incidence of this syndrome is approximately one in fifty thousandlive births and it affects both genders equally. It affects structures which are derivatives of theprimary and second brachial arches. The foremost common manifestations of TCS are theantimongloid slanting of the palpebral fissures, colobomas of the lower eyelid, hypoplasia ofzygoma and mandible and a spread of ear abnormalities. People with Treacher Collinssyndrome usually have normal intelligence.This article describes clinical and radiographicfeatures of TCS in a 29 yr old male who had reported to the department of Oral Medicineand Radiology with the complaint of forwardly placed upper and lower front teeth since birth.Alsopathogenesis, diagnostic procedure, diagnosis based onscore, management andpreventive aspects are discussed.

The seasonal effect on the F2 sublayer critical frequency of the ionosphere (foF2), during one-day-shock, at Ouagadougou station during three solar cycles (20, 21, and 22) is examined in this work. It appears that summer has an effect tending to decrease the values â€‹â€‹of foF2 in the maximum, ascending and descending phase. At solar cycle maximum, winter and autumn do not modify the foF2 amplitudes. At solar cycle minimum, winter decreases foF2 values â€‹â€‹in the morning (08:00 a.m. to 1:00 p.m.), while spring amplifies them (09:00 a.m. to 1:00 p.m.). In the ascending phase, winter, spring and autumn increase foF2 values â€‹â€‹in the morning. In the descending phase, winter and autumn do not modify the foF2 values â€‹â€‹while spring increases them.
MEDICINE OF HIPPOCRATES
Authors:   Ibn Sina Institute of Tibb, Johannesburg, South Africa., Bhikha Rashid
Published: December 2022

In recognition of his contribution to the medical field, Hippocrates is universally known as the Father of Medicine. He transformed medicine from superstition and magic to a scientific and evidence-based system. The core focus of Hippocratic medicine is an individualistic approach based on Vis MedicatrixNaturae- the healing power of nature, which acknowledges the uniqueness of each individual, as well as the effects of lifestyle in health and disease.More significantly, Hippocrates hypothesised thehumoral theory. Furthermore, he advised on the importance of professionalism and medical ethics with respect to bedside manner, benevolence, and conduct. This led to the origin of the Hippocratic oath as we know it today. Ultimately, there is no era of medicine which is unmarked by Hippocrates. He laid the foundation of what is the essence of medical science today, including rationalism, ethics, patient care, observation skills and clinical experience. This paper focuses on the acknowledgement of Hippocrates, highlighting his contributionsin medicine to this day.

As the quest for better ways to present science to the new generation of students continues to occupy the thoughts of science educators across the globe, so will new approaches such as the Culturo-Techno-Contextual Approach (CTCA) continue to emerge in response to thisquest. This study explores the potency of CTCA in breaking the barriers to meaningful learning of electrochemistry. The explanatory sequential design was employed. A total of 141 secondary school (II) students from two purposively selected schools in Lagos State education district V participated in the study. The electrochemistry achievement test which had a reliability coefficient of 0.78 was the instrument used to collect the quantitative data. Treatment lasted five weeks after the conduct of the pretest, the experimental group was taught using CTCA and the control group was taught using the traditional lecture method. Four weeks after the posttest, the retention test was conducted. One-way ANCOVA wasused to analyse the data. The experimental group outperformed the control group, but CTCA had no differential impact on students in the experimental group based on gender. Within the limitations of the study, we concluded that CTCA is capable of promoting meaningful learning in chemistry. Implications of the study were highlighted.

Circular RNAs (circRNAs) are a class of non-coding RNAs with a circular, covalent structure, which are highly conserved, stable unique molecules found in eukaryotic cells. The most notable character of circRNAs is their high stability in biological systems which is a key factor in their potential for use in a variety of RNA-focused medical applications. Despite the fact that circRNAs have a wide range of biological roles and regulatory functions, their circular structure and sequence overlap with their linear mRNA counterparts make it difficult to research them in depth. Furthermore, little is known about their function in viral infections and in immune responses.Since circRNAs have been found to be involved in a number of viral infections (including hepatitis B virus infection and human papilloma virus infection), their significance in viral infections is being more recognized in the last years.In this review, we aimed to provide a broad basis and overview on the biogenesis, significance and regulatory roles of circRNAs in the context of viral hepatitis C virus (HCV) infection, and HCV related hepatocellular carcinoma. Owing to the fact that the chronic HCV infection is the leading cause of HCC in the western countries especially Egypt. HCV can act directly on cell signaling pathways to promote HCC by inhibiting tumor suppressor genes or by causing activation of signaling pathways that up-regulate growth and division. Because viruses frequently manipulate cellular pathways to control viral gene expression, cellular and viral circRNA landscapes in virus-infected cells are altered. Studying the contribution of circRNAs in these pathways may give valuable information in the pathogenesis of HCC caused by HCV or in finding more reliable therapeutic approaches.

Published: December 2022

This work describes the successful application of the pore volume and surface diffusion (PVSD) model characterizing the batch adsorption of Cu(II) on a chemically modified Cucurbita moschata biosorbent. The PVSD model captures the convective transport of Cu(II) from the bulk solution to the biosorbent surface, followed by its surface and pore diffusion inside the biosorbent. The adsorption of Cu(II) is mimicked using the Langmuir isotherm. The algebraic, ordinary, and partial differential equations, involved in the PVSD model, are solved using the general process modeling system (gPROMS). The model simulation results, depicted by the Cu(II) concentration decay curve, show an excellent match with experimental data. The external mass transfer coefficient (≈10−3 m/s) indicated no restriction on approaching Cu(II) toward the biosorbent surface. Within the biosorbent, surface diffusion was dominant over pore volume diffusion. The statistical analysis of the PVSD model results has been done by calculating R2, Chi-square value, normalized standard deviation, p-value, and root-mean-square error. The PVSD model approach presented in this work could be beneficial to other heavy metal–biosorbent systems.

Published: December 2022

Water supply is one of the important functions provided to humans by the ecosystem. Water supply by the ecosystem leads to sustainable economic development, ecological restoration and food security for human societies. Therefore, the evaluation of the water supply capacity of the ecosystem and the analysis of its spatial distribution features play an important role in the implementation of the plan for the protection and exploitation of water resources. Evaluation of ecological economic balance is of great importance in sustainable ecosystem management. This paper was conducted to develop the ecological economic balance structure based on the water supply and land cover changes. Land use was considered in four time periods from 2000 to 2021 with seven-year intervals to evaluate the process of land cover change and water availability. The results showed that the southern and eastern regions addressed a negative trend in the ecological economic balance. These areas have been affected by population growth and urbanization.

Investigation with participation of the first- to fourth-year female students of the flight school in Krasnodar had the purpose to ascertain that sizes of the present pilot gear fit modern types of the female body. It was found out that sizes of many female students are below minimal ranges of the pilot gear fit. The quantity of these female students varies from 11 % (anti-g suits) to 100 % (O2 masks). The group of female students was actually representative of the women of the same age in this country. We conclude that the existing misses' sizes do not fit the anthropometric parameters of female candidates for flight training. To sum up, there is need to revise the size ranges of the flight gear with consideration of modern types of the female body.

Spore-forming bacteria are residents on the International space station (ISS) and can act as potential biodistructors of structural materials with a consequent disturbance of equipment operation. These bacteria demonstrate high resistance to many stress factors. Molecular mechanisms of this resistance are poorly understood. Sanitary/hygienic monitoring resulted in detection and isolation of strain Bacillus pumilus 25. The investigation was aimed to test B. pumilus 25 resistance to oxidative agents, antibiotics, and to analyze expression of genes associated with the cell response to DNA damage and hydrogen sulfide production. The strain was identified by sequencing 16S RNA and MALDI-TOF analysis. Resistance to stresses and antibiotics was tested with the use of standard microbiological methods. Level of mRNA genes was determined with the real-time polymerase chain reaction. Our results evidence for heightened B. pumilus 25 resistance to the oxidative stress and majority of the antibiotics used in the investigation. This resistance seems to be associated with high expression of the ku-ligD operon genes, and elevated production of hydrogen sulfide.
An Exhaustive Study on Deep Neural Network-based Prediction of Heart Diseases and its Interpretations
Authors: Nagaraj Jothiaruna , A. Anny Leema
Published: December 2022

Cardiovascular disease prediction is important in day-to-day life. A tool to diagnose cardiovascular diseases is an Electrocardiogram (ECG), which records electrical activities happening in the heart through a wave. A determination is made by checking the wave changes in an ECG. Predicting wave changes and diagnosing the disease requires domain expertise like cardiologists/physicians. Deep Neural Network techniques extract the features accurately and automatically predict the type of disease. This article lists different types of cardiac disorders, and parallelly different disease interpretations of all types of diseases are discussed to manually identify the disease type; segmentation of leads, pre-trained models, and different detection techniques are discussed to predict the type of diseases from an ECG image. Finally, this article discussed the different challenges in predicting heart diseases, and solutions to some of the challenges are given.
Advances in Durable Resistance to Diseases in Staple Food Crops: A Review
Authors: Kozub Natalia , Sozinova Oksana , Sozinov Igor , Karelov Anatolii , Janse Liliya , Mishchenko Lidiya , Borzykh Oleksandr , Blume Yaroslav
Published: December 2022

Background:

At all stages of their development, plants are in permanent contact with causative agents of various diseases. Mechanisms of disease resistance and its durability in crops largely depend on the pathogen’s lifestyle, namely the nutrition mode and host range.

Objective:

The objective of this review is to consider the main advances in the production of genotypes with durable disease resistance in the globally important food crops, wheat, rice, and potato, as well as barley.

Results:

In wheat, durable resistance could be provided by the employment of various adult plant resistance genes against biotrophic pathogens, whose action commonly does not involve hypersensitivity response, as well as major quantitative genes, including mutants of susceptibility alleles, against necrotrophs via marker assisted selection (MAS). In barley, the most prominent example is the gene mlo conferring durable powdery mildew resistance, but it is compromised by higher susceptibility to some necrotrophic fungi. A few genes for broad-spectrum resistance against the rice blast and bacterial blight pathogens confirmed their effectiveness for decades, and they could be combined with effective R genes via MAS. Resistance to late blight of potato is mainly provided by R genes introgressed from wild potato species, which could be pyramided with quantitative trait loci. Genes for extreme resistance to potato viruses derived from related species provide durable and broad-spectrum resistance and could be effectively deployed in potato breeding using MAS. Silencing susceptibility genes by genome editing technologies is the most promising approach to produce plants with durable resistance to many pathogens in the crop species. Genetic transformation with genes for resistance-associated proteins or constructs providing silencing via RNA interference is an effective biotechnological method to generate plants with durable resistance against pathogens, especially viruses.

Conclusion:

Main advances in the production of crop plants with durable resistance are based on studies of molecular mechanisms of plant immunity and its special features for pathogens with different lifestyles via the use of biotechnological approaches such as MAS for pyramiding of monogenic quantitative resistance genes or qualitative R genes, changes in expression of certain genes associated with resistance, the introduction of transgenes, mutagenesis and genome editing aimed at silencing susceptibility genes.
Improvement of Wheat Genetic Resistance to Powdery Mildew Retrospects and Prospects
Authors: Ternovska Tamara K. , Iefimenko Tetiana S. , Antonyuk Maksym Z.
Published: December 2022

Powdery mildew is one of the most noticeable and harmful wheat diseases in countries with temperate climates and sufficient rainfall. The most efficient, economical, and environmentally friendly means to control powdery mildew is the growing of genetically resistant wheat cultivars. The genetic resistance of wheat is quickly overcome due to the evolution of the avirulence genes of the pathogen. The problem of enriching the genetic pool of wheat with new effective resistance genes is relevant. The objective of the work is to show that the basis of the organization of the genetic protection of wheat from powdery mildew cannot be related to the simple expansion of the wheat genetic pool due to new resistance genes. The gene transfer should be preceded by the study of the molecular nature of the resistance gene products. The work presented information about resistance types in wheat against powdery mildew and the molecular nature ofPmgenes’ products. They are NLR-immune receptors, tandem kinase proteins, receptor-like kinases, transporters, plant-specific proteins, and mitogen activated kinases. NLR, in interaction with the pathogen effectors, confers highly specific resistance; all the rest provide resistance of a wide spectrum. Characteristics of pathogen gene products are provided, and a model of interaction betweenPmandAvrPmgene products is described. A certain number ofPmgenes are present in the current genetic pool of common wheat. The effectiveness of some of the most common genes has already been overcome by the pathogen. This necessitates the renewal of resistance genes in wheat. Prospects for the improvement of wheat genetic resistance to powdery mildew are provided. The prospective direction of research for providing effective long-term wheat genetic resistance to the biotrophic pathogen Blumeria is molecular genetic studies of wheat plants and pathogen races. A clear understanding of the molecular nature of the plant protein conferring resistance and its role in the development of the molecular pattern of plant protection against the pathogen is necessary to assess the prospects of any resistance gene for transfer to the genetic pool of wheat in relation to its ability to confer effective and long-lasting powdery mildew resistance.

Summer schools are an important element of universities’ international strategies. During the COVID-19 pandemic, however, they often had to be canceled due to health-related concerns and political guidelines. The partner universities A (Finland) and B (Germany) decided to offer their summer schools in a virtual format in 2021 to allow students to gain international experience from their home country and to maintain international relations during the pandemic. By evaluating the success of their summer schools and sharing their experiences, they found that virtual summer schools have great potential. For certain students (with jobs, limited financial resources, mobility impairments, families to care for, etc.), virtual summer schools are particularly suitable and might even represent the only possibility to gain international experience. For virtual summer schools to be successful, however, universities have to consider organizational and pedagogical questions. In this article, organizers from A and B share their lessons learned as an inspiration for other institutions planning virtual summer schools that are immersive and engaging.
Staging Uncivility, Or, The Performative Politics of Radical Decolonial Iconoclasm
Authors: Pauwels Matthias
Published: December 2022

In this article I reflect on the deployment of crass vandalism in contemporary decolonial and anti-racist struggles, as exemplified by the recent activist campaign against Belgium’s colonialist patrimony. Through a consideration of two internal, “enlightened” critiques of such vandalist activism, I argue that an irresolvable, recurrent conflict between two fundamental performative politics, based on the performance of civility and barbarity respectively, plays itself out here. In recourse to arguments by Benjamin, Žižek, Jameson and Fanon, I offer a redemptive critique of the second type of politics and examine the “paradoxical efficacy” of “staging barbarity” for decolonial, anti-racist purposes.

This study aimed to describe the difficulties of vocational education teachers in applying the teachings of Tamansiswa Ki Hadjar Dewantara (KHD) method in the learning process. This study used the descriptive qualitative approach that was chosen to reveal the existing phenomena based on the perspectives of 12 vocational education teachers. The data collection techniques used in-depth interviews and observation. The study results reveal that teachers still limit the teachings of Tamansiswa KHD. All teachers only know the basics of concepts, and even then, they cannot elaborate more deeply on the concepts of the teachings. The teacher admitted that it was difficult to apply the teachings during the learning process and received confirmation directly from the results of observations, which found no teaching activity for Tamansiswa KHD during the learning process and in the teachers' plan. Various socialization and training are needed to provide a comprehensive understanding for teachers in applying these teachings in learning so that their character values can be reflected in students.

Teachers play an essential role in developing material for distance learning for students with special needs, fulfilling the practical principle, flexibility, the ability to accommodate the learning requirements, and the ability to ease students to understand the material through independent learning. However, many obstacles still hinder teachers in the execution. Through a survey of 115 special education teachers in the Special Region of Yogyakarta, this study is aimed at describing teachers' needs in developing distance learning material from the aspect of physical forms, teaching material delivery, and obstacles faced by teachers. The data were obtained through an open questionnaire and analyzed with a descriptive quantitative approach. In addition, the data were presented with presentations, figures, and narrative interpretations. The result shows that 87% of teachers require learning material in the form of a module, and 93.81% of teachers require teaching material content about understanding the concept of daily activities for students' independence. Teaching materials in the form of practical activities delivered with colored pictures are required by 16.28% of teachers. 23.33% of teachers are faced with obstacles to accommodating the diversity of students' characteristic conditions and learning needs. In conclusion, distance learning management and teaching material development to ease students with special needs in learning is an urgent matter in special education services. In addition, it requires preparation through teacher competency improvement.

Analysis of the existence of memory phenomena in model heterostructures based on doped ferrite La0.5Sr0.5Fe0.75Al0.2Ni0.05O3-δ with a perovskite structure has been carried out. It was demonstrated that one 5-10 μm thick ferrite layer sandwiched between Pt and Ni electrodes exhibits an analog memristor behavior. Under positive polarity, this heterostructure shows a smooth increase in electrical conductivity, with an opposite effect under negative polarity. Such phenomena are presumably associated with changing local concentrations of oxygen vacancies due to their drift in the electric field. Since lanthanum-strontium ferrites are sufficiently tolerant with respect to oxygen non-stoichiometry variations, no dendrite growth due to reductive decomposition is observed. The current vs. voltage dependencies display a strong nonlinearity resulting the Poole-Frenkel effect, namely, a decrease in the activation energy of electron holes trapped on oxygen vacancies. In addition to the Poole-Frenkel effect, pre-exponential factor of the conductivity vs. temperature dependence also increases under electric field, indicating an increase in the effective electron-hole mobility.

The impedance spectroscopy in the temperature range 302–779 K was used to study the ionic
conductivity of the Pr0.9Pb0.1F2.9 nanoceramics, obtained by cold pressing of the powder, mechanically synthesized from components of PbF2 and PrF3. The studied material is the solid solution with tysonite-type structure (sp. gr. P-3c1, Z = 6) and lattice parameters a = 7.0906(4) and c = 7.2538(4) A. With increasing temperature, the conductivity of the ceramic increases from 1.9 × 10–5 to 6.7 × 10–2 S/cm, and the activation enthalpy of ion transport Hσ = 0.407 ± 0.005 and 0.345 ± 0.005 eV at 302–502 and 502–779 K, respectively. The electrical conductivity mechanism is due to the migration of fluorine vacancies along the boundaries of nanocrystalline grains. The intragranular conductivity of ceramics is close to the electrical conductivity of a single crystal of the same composition. Cold pressed ceramics Pr0.9Pb0.1F2.9 can be used as a promising solid electrolyte in ”room" fluorine-ion current sources.

Glass formation processes in condensed matter are characterized by some specific short-range order changes in the arrangement of particles (atoms/molecules/ions). So, the short-range structural order in supercooled liquids and glasses is characterized by fivefold symmetry in the arrangement of particles, often referred to as icosahedral (ideal or distorted) short-range order. This article is devoted to the study of local structural features of the supercooled melt of the A20B80 fullerene mixture (where A = C60 and B = C70) obtained under various cooling protocols in order to elucidate the mechanism of formation of the icosahedral short-range order in binary molecular liquids. Comprehensive studies of the properties of a fullerene mixture melt were carried out using large-scale molecular dynamics simulations followed by structural and cluster analysis. The crystallization temperature and the critical glass transition temperature of the system were calculated to be Tm ≈ 1439 K and Tc ≈ 1238 K, respectively. It has been established that the crystallization of a binary fullerene mixture proceeds according to the polycrystalline scenario with the formation of clusters with fcc and hcp symmetries. It is shown that in a supercooled fullerene mixture, the short-range icosahedral order is formed by an insignificant number of ideal icosahedral clusters and a certain set of distorted icosahedral clusters, the fraction of which remains practically unchanged at temperatures below the critical glass transition temperature.

We report the seminal approach for localization of photocarriers in a photoconductive antenna (PCA)-emitter via the focusing element comprising the sapphire fiber. Using numerical simulation, we showed that at the certain ratio between the fiber diameter and the gap size, i.e. d/g = 22.5, one can attain a 35-fold enhancement of the laser irradiation in vicinity of the PCA electrodes. This provides the formation of subwavelength EM wave caustics located at the edges of the PCA electrodes which potentially gives rise to an increase of optical-to-terahertz conversion efficiency.
