Reports on the materiality of disability in the face of the Covid-19 pandemic from a damaged land
Authors: Meinerz N , Allebrandt D , Vasconcelos J Aga
Published: September 2021

This article aims to describe changes in the routine of people with disabilities in face of Covid19 pandemic and the ongoing coping measures underway in the state of Alagoas, in northeast Brazil. Data from in-depth interviews with subjects marked by different experiences of visual, hearing, motor and intellectual impairment are analyzed here. Participants are part of an extension project, started in 2019, under the responsibility of the first author of this article. The project changed the routine of the university in face of the presence, circulation and engagement of bodies and minds that escape the conventions of normality in the academic space. The interactions, mediated by a series of applications of digital communication, addressed the following issues: 1) the loss of individual and/or family income resulting from the pandemic, and its impact on their material conditions of existence; 2) the emergence of new demands related to physical and mental health as well as changes in previous therapeutic strategies; 3) the characterization of access to communication technologies, the new possibilities and restrictions for maintaining extra-family bonds, such as contact with friends, participation in social mobilizations and in academic activities. In the analysis, we focused on the mutual dynamics of care, especially the engagement in support and assistance practices from family and friends. The attention to changes in the environment from the different collective demands in face of the pandemic exposes some displacements in the ways of embodying disability as well as the ability to give powerful responses to complex demands for adaptation. The intersection between different social markers of difference, like race, gender and class is also central to the identification of continuities, which involve the pre-existence of physical distance as a reality of disability.

In this study, it is aimed to compare the ethical, transformational, paternalistic, spiritual, and instructional leadership styles of school principals. For this purpose, the research has been carried out according to the survey model. 586 teachers from Istanbul province participated in the study. A high level of a positive correlation has been found between the leadership styles of school administrators perceived by the teachers. Teachers most perceived ethical leadership style and least perceived paternalist leadership style of school administrators. While teachers' perceptions of instructional, transformational, ethical, and spiritual leadership styles differ significantly according to their gender; It does not differ significantly according to their educational status. It has been determined that the instructional, transformational, ethical, paternalist, and spiritual leadership styles of school administrators differ significantly according to the type, grade, and age variables. The instructional, transformational, paternalist and spiritual leadership styles of school principals do not differ significantly according to the seniority variable; however, it has been determined that the ethical leadership style of school administrators differed significantly according to the seniority variable. It has been determined that instructional, transformational, ethical, paternalist, and spiritual leadership styles of school administrators differ significantly; according to the type of schools, grade, and age variables.

Dental neglect is a common condition among children and it can be associated with several adverse events as dental caries, dental pain and inflammation, infections, trauma, bleeding and other complications that might result from inadequate administration of adequate prevention and treatment modalities. However, many children and parents are not adequately aware of these events and the potential diseases that might be associated secondary to them. Dental neglect is a common condition that might affect children of different age groups and might also extend to adult groups and is affected by the demographics and socioeconomic characteristics of the affected populations. Furthermore, the etiology of dental neglect is variable and parenteral, child and clinical care should all be integrated to achieve better oral health. Many adverse events have been reported as dental caries and other periodontal diseases that might have a significant impact on the affected teeth and the succeeding permanent ones, which might impact the quality of life in the affected children. Accordingly, dental neglect should be given full care to enhance the outcomes of oral health in children.
A comparative study of bone marrow aspirate with trephine biopsy in pancytopenia disorders
Authors: J Kavya , Kumari MK Kalpana
Published: September 2021

Pancytopenia is commonly reported in clinical hematology practice. Due to its varied marrow pathology and underlying ailments, diagnosis is often misleading and delayed. Bone marrow examination would provide a comprehensive diagnosis of both blood and bone marrow, since aspirate investigates the cytological morphology and biopsy evaluates the cellularity, architecture, and compact marrows.

To compare bone marrow aspiration and trephine biopsy results in the diagnosis of pancytopenia, and to determine the sensitivity and specificity of aspirate examination in pancytopenia diagnosis.

This prospective study was conducted at a tertiary care hospital from July 2014 to June 2016. A total of 320 samples were received at the department of pathology for bone marrow examination (aspirate and biopsy). Romanowsky (Leishman) stain was used to investigate aspirate samples. All biopsy samples were processed into 3-5 μ blocks and stained using hematoxylin and eosin after decalcification with 5.5% EDTA. Data analysis was performed using SPSS19.

Pancytopenia constituted 56 (18.7%) cases with the mean age of 41.79 years. Of the total pancytopenia cases, hematological disorders constituted 50 (89.3%) cases and 6 (10.7%) were non-hematological cases. Aspirate and biopsy diagnosis positively correlated in 76.79% of cases. A 100% sensitivity and specificity of aspirate diagnosis was observed in, acute myeloid leukemia, hypersplenism, myelodysplastic syndrome, megaloblastic anemia, hematological malignancy in remission and negative for lymphoma infiltrate. Aspirate had no role in diagnosis of uremic osteodystrophy and myelofibrosis, whereas leishmaniasis was diagnosed on aspirate alone.

Pancytopenia includes multiple underlying ailments which requires a differential diagnosis approach. Combining both aspirate and biopsy for diagnosis would benefit the patient in prognosis as they are complementary to each other.

Published: September 2021

Oral submucous fibrosis (OSMF) is a potentially malignant disorder characterized by juxtaepithelial inflammation and progressive fibrosis of submucosal tissues. It may affect any part of the oral cavity, as well as pharynx and oesophagus. The pathogenesis of OSMF may be attributable to habitual chewing of areca nut and its products, which is more prevalent amongst young population of South East Asia and India. Various histopathological features in different tissue components- epithelial, connective tissue stroma, muscle and salivary gland may be observed along the course of this chronic disorder. In connective tissue, extensive fibrosis with progressive hyalinization of collagen fibers and muscles accompanied by inflammatory response is considered to be pathognomonic feature. Advanced stages of OSMF may show atrophic changes or even dysplasia in the epithelium which may undergo malignant transformation. Malignant transformation rate of OSMF has been proved to be around 7.5%. Thus, identification of early histopathological changes in OSMF can lead to improved survival rates. The present article illustrates the various histopathological features observed during different stages of development of OSMF. A better understanding of the correlation between histopathological features and corresponding clinical manifestations can aid dental surgeons in prognostication of the lesion and determining response to treatment.

Published: September 2021

Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma that carries a favourable prognosis. However, a small subset unfortunately shows transformation to least differentiated anaplastic carcinoma (AC) having a highly aggressive behavior. This process usually occurs within thyroid but is rare in metastatic cervical lymph node or soft tissue neck and exceedingly rare at distant sites. We report a unique case of a 75 years female who presented with anaplastic carcinoma in metastatic neck deposit with occult papillary thyroid carcinoma. To the best of our knowledge, this is the first case in the world literature having anaplastic transformation (AT) in the metastatic neck deposit, right at the presentation with a totally unnoticed PTC clinically. We present this case to emphasize that the transformation process can occur even when the differentiated malignancy in thyroid is small, insignificant or hidden and that metastasis solely can be the presenting feature which can be misleading clinically and even histopathologically. As AC is very aggressive, there is need for early and precise diagnosis & prompt therapeutic intervention.
Embedding Non-planar Graphs: Storage and Representation
Authors: Klisura Ðorže
Published: September 2021

In this paper, we propose a convention for repre-senting non-planar graphs and their least-crossing embeddings in a canonical way. We achieve this by using state-of-the-art tools such as canonical labelling of graphs, Nauty’s Graph6 string and combinatorial representations for planar graphs. To the best of our knowledge, this has not been done before. Besides, we implement the men-tioned procedure in a SageMath language and compute embeddings for certain classes of cubic, vertex-transitive and general graphs. Our main contribution is an extension of one of the graph data sets hosted on MathDataHub, and towards extending the SageMath codebase.
Fast Recognition of Some Parametric Graph Families
Authors: Klobas Nina , Krnc Matjaž
Published: September 2021

Recognizing graphs with high level of symmetries is hard in general, and usually requires additional structural understanding. In this paper we study a particular graph parameter and motivate its usage by devising eÿcient recognition algorithm for the family of I-graphs. For integers m a simple graph is cycle regular if every path of length ` belongs to exactly cycles of length m. We identify all cycle regular I-graphs and, as a conse-quence, describe linear recognition algorithm for the observed family. Similar procedure can be used to devise the recog-nition algorithms for Double generalized Petersen graphs and folded cubes. Besides that, we believe the structural observations and methods used in the paper are of independent interest and could be used for solving other algorithmic problems.

Mecanismos de resistencia. Intervenciones del arte y el cuerpo en los procesos de resignificación del Centro Histórico de Lima
Authors: Espinoza Mendoza Lidia
Published: September 2021

Hacia fines del siglo XX, las constantes crisis políticas y sociales que vivió el Perú motivaron la transformación del Centro Histórico de Lima y lo convirtieron en el escenario de diversas manifestaciones sociales, políticas y artísticas. La producción social del espacio, en el entorno urbano histórico de la ciudad, partió tanto del accionar institucional como de las intervenciones que transgredieron el orden establecido —de manera eventual y efímera— como parte del accionar ciudadano. El presente artículo propone una revisión de aquellas intervenciones que tuvieron lugar en el espacio público representativo del poder, el Centro Histórico, y que llegaron a resignificarlo mediante el accionar cívico-artístico. En esta cronología, la espacialidad del cuerpo, o el cuerpo colectivo, aparece en la acción artística como una herramienta constante, y como mecanismo para generar reflexión y crítica en torno a la producción del espacio público y su relación con la arquitectura.

Authors: Mrudula G. , Rani P. Sandhya , Sreekanth B. , Madhuri K.V. Naga , Luther M. Martin
Published: September 2021

Background: Zn deficiency was predominant in soils of Chittoor district of Andhra Pradesh, which causes yield reduction in most of the crops especially in finger millet. Zinc has important role in enzyme activation viz., oxidoreductase, transferases, hydrolases, lyases, isomerases and ligases. The deficient soil gives us the zinc deficient food which is said to be the major root cause for malnutrition among the children. Hence present study was intended to find out most appropriate method and time of zinc fertilization for higher productivity, grain quality and zinc fortification with two major finger millet varieties viz., vakula and tirumala. Methods: The field experiment was laid out in split plot design with three replications and two varieties viz., vakula (V1) and tirumala (V2) with seven zinc application treatments which includes: control (T1); NPK (30-30-20) + FYM @ 10t ha-1 (T2); T2 + soil application (SA) of ZnSO4 @ 25 kg ha-1 as basal (T3); T2 + SA of chelated zinc sulphate @ 5 kg ha-1 as basal (T4); T2 + FA of 0.2% ZnSO4 at ear head emergence stage (T5); T2 + foliar application (FA) of 0.2% ZnSO4 at grain filling stage (T6); T2 + FA of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7). Result: Foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stages registered significantly highest grain and straw yield of 3150 kg ha-1 and 7364 kg ha-1, respectively compared to control and other zinc fertilization treatments. Between the two tested varieties tirumala variety recorded higher grain yield (2298 kg ha-1) compared to vakula variety (2230 kg ha-1).

Published: September 2021

Background: Kashmir Valley, one of the temperate regions of India, has experienced an exponential increase in the milk-production over the last decades. This may be mainly attributed to massive cross-breeding of ‘Local Cattle of Kashmir Valley’ with the world-class dairy breeds like Jersey and Holstein-Friesian (HF), popularly known as Jersey-Crossbreds (JCB) and Holstein-Friesian Crossbreds (HFCB), respectively. However, no specific guidelines on their breed characteristics is available, which is crucial for their establishment, recognition and management. Precise and standardized morphological details are a primary requisite for application of advanced technologies like automation, Internet of Things (IoT) and robotics. Therefore, the present study aimed to characterize the HFCB and JCB cows. Methods: Morphologic and morphometric traits of 600 and 447 cows respectively, reared in the Srinagar district of Kashmir, were studied in detatil as per the standard methods. The null-hypothesis set was that the two crossbreds do not differ from each other. Result: It was observed that two crossbreds differed significantly (p less than 0.05) with each other in respect of the morphological and morphometrical traits like body size and weight. The study generated a baseline data on these two crossbreds, which is critical not only for their recognition, welfare and scientific management, but shall also act as a reference for global researchers to assess the results of crossbreeding superior dairy breeds in improving the genetic-merit of other breeds worldwide.

Background: Hassan sheep is the third most populous breed of the five registered sheep breeds from Karnataka with limited studies on its morphological and carcass characteristics. Hence, the study was undertaken to know the present status of morphological and carcass characteristics of this breed. Methods: A total of 34 randomly selected flocks were surveyed and the data on various parameters were collected. The morphometrical data was collected on 344 sheep belonging to eight flocks from the breeding tract. The carcass characteristics were documented by slaughtering six male lambs (between nine to twelve months of age). Result: These sheep had varied coat colours viz. complete white (23.3%), white with light brown patches (58.1%) and white with black patches (18.6%) on head and neck region. It was observed that 40.4 per cent of males and only 1.4 per cent of females were horned. Atrophied ears were noticed in 2.3 per cent of these sheep. The average adult body length (cm), height at wither (cm), chest girth (cm), paunch (cm), ear length (cm), tail length (cm) and average adult body weight (kg) were 66.4±0.62, 65.03±1.45, 75.2±1.02, 76.5±1.38, 15.2±0.07, 11.5±0.07 and 32.7±2.03 in males and 63.8±0.85, 61.7±1.38, 71.8±2.32, 74.5±2.60, 15.0±0.34, 11.3±0.08 and 27.8±1.21 in females, respectively. The difference in body weight between males and females increased significantly over the age. The pre-slaughter weight (PSW), hot carcass weight (HCW) and dressing percentage recorded were 20.3±1.42 Kg, 9.5±0.23 kg and 46.80 per cent, respectively.
​Caprine Respiratory Mycoplasmosis (Contagious Caprine Pleuropneumonia CCPP)- A Global Perspective of the Disease, Epidemiology, Diagnosis, Chemotherapy and Immunization: A Review

Published: September 2021

Mycoplasma infection of the respiratory tract of goats is prevalent worldwide including the South Asian sub-continent. Owing to intensive and large scale goat farming, the incidence of the disease is on an increase. Among various species of mycoplasma, Mycoplasma capricolum subspecies Capri pneumoniae is increasingly incriminated in Contagious Caprine Pleurapneumonia (CCPP) in goat populations with considerable economic fallout in the form of high morbidity and mortality. The disease manifestations in caprines are recorded as anorexia, high febrile reaction and respiratory embarrassment in the shape of clinical dyspnoea, polypnea, paroxysmal cough and sero-purulent nasal discharges. The disease is thus contracted by the healthy animals through aerosol, contaminated feed and water sources in the herd premises, without a protective immunity and that the conferred immunity in recovered cases being short-lived. The true lesions of CCPP are confined to the lung alveolar tissues of infected goats, which distinguish it from other respiratory diseases of small ruminants caused by the members of the Mycoplasma mycoides cluster. Atypical pneumonia caused by the mycoplasma infection of goats, also known as Contagious Caprine Pleuropneumonia (CCPP) has been more often reported from Africa and Asia than Europe. Classical, acute CCPP attributed to Mycoplasma capricolum subsp. Capri pneumoniae, originally known asthe F38 biotype (World Organisation for Animal Health, 2008) causes heavy kid mortality. Two other organisms in this group, M. mycoides subsp. capri and M. mycoides subsp. mycoides large-colony type, can cause disease in small ruminants that clinico-pathologically mimics CCPP but may have extra pulmonary signs and lesions, sometimes. Mycoplasma Capri pneumoniae and other members of the M. mycoides cluster cross-react in serological tests and share biochemical and genetic similarities. The most favourable epidemiological scenario in the Sub-continent is the hot humid climate during monsoons. The diversity and multi-etiological subspecies involved in the disease is detrimental in the development of an effective vaccine even though in some places a liquid vaccine is presently in use. At other places, anti-mycoplasmal antibiotics of aminoglycoside and fluoroquinolone and perhaps the macrolide groups remain to be the main option in preventing flock mortalities.

Authors: Paudel Anju , Resnick Barbara , Galik Elizabeth
Published: September 2021

Background and Purpose

The Cohen-Mansfield Agitation Inventory (CMAI) is a widely used measure of agitation. The purpose of this study was to test the internal consistency, reliability, and validity of short-form CMAI in a sample of nursing home residents with cognitive impairment and examine if it is invariant across gender.

Methods

This study utilized baseline data from a randomized trial including 553 residents from 55 nursing homes. Data was analyzed using structural equation modeling.

Results

Confirmatory factory analysis supported the three-factor structure including aggressive (α = .794), physically nonaggressive (α = .617), and verbally agitated (α = .718) behaviors. Invariance testing confirmed that the shortened measure is invariant across gender.

Conclusions

Findings provide validity evidence of short-form CMAI to assess agitation and gender differences in agitation in nursing home population.

Published: September 2021

Background and Purpose: How the Area Deprivation Index (ADI) performs compared to other measures of socioeconomic status (SES) is unknown. The study purpose is to compare the ADI and other measures of SES in their ability to predict pain severity/interference. Methods: Four measures of SES were compared—ADI, income, education, and subjective social status (SSS). Results: Pain severity/interference correlated positively with ADI (r = .396/r = .33), and negatively with income (r = –.507/r = –.428) and education (r = –.271/r = –.102). Criterion scores of the pain severity model suggest income performs best (AIC = 428.29/BIC = 436.22), followed by ADI (AIC = 437.24/BIC = 445.17), with education performing least well (AIC = 446.35/BIC = 454.29). Similar results were seen for the pain interference model. Conclusions: Neighborhood-level factors warrant consideration along with individual-level factors when attempting to understand the impact of SES on chronic low back pain.

Authors: Ginzburg Tatyana , Azuri Eyal , Hoffman Robert , Moshe Shlomo , Azuri Joseph
Published: September 2021

Background and Purpose

Diabetes control measures were shown to improve, following multidisciplinary intervention managed by a nurse in short-term follow-ups. However, there is a lack of data regarding the long-term effects of such interventions. We assessed long-term diabetes management and control measures in a central multidisciplinary primary care clinic, following a brief intervention conducted by a community nurse.

Methods

A cross-sectional study in a central, multidisciplinary, primary care clinic. A previous study cohort of randomly selected 100 people with diabetes was followed-up for over 10 years, following a brief intervention managed by a community nurse. Data of diabetes control measures (e.g., hemoglobin A1c [HbA1c], low-density lipoprotein [LDL], and blood pressure) and clinical use of medical services (e.g., nurse, physician, dietician, and hospitalizations) were extracted from the medical records and compared from before the intervention to short and long-term follow-ups (median of 25 months, 10.56 years respectively).

Results

During the follow-up period, 18 participants (median age at intervention time 73 years) died. HbA1c dropped significantly (p < .001) from before to after the intervention, and remained low. LDL and Systolic Blood pressure decreased and continued to decrease during the long-term follow-up. While the number of nurse visits per year increased, physician and dietician visits decreased. Annual foot examinations and ophthalmologist visits, which increased following the intervention, remained high. Diabetes-related hospitalizations also decreased from the point of intervention.

Implications for Practice

Multidisciplinary, brief intervention managed by a community nurse, improve, and even continue to improve, most diabetes management and control measures, for more than 10 years following the intervention.

Published: September 2021

The use of renewable fuels may be an action leading to the reduction of pollutant emissions. This group includes biobutanol as a product of biomass fermentation. Some of its physicochemical properties, including the ability to mix with hydrocarbon fuels, make it suitable for use as a fuel component for marine diesel engines. The article presents the results of research on the concentration of exhaust gas components of a Sulzer 6AL20 / 24 diesel engine powered by a mixture of n-butane and diesel oil. The emission intensity were calculated for the tested components: carbon monoxide, carbon dioxide and nitrogen oxides. The emission intensity surface graphs were created based on the calculated data. The tests were carried out using different concentrations of the mixture of n-butanol and marine fuel.

The paper discusses and analyzes the design parameters of timber transport roads. The possibility of improving the quality of design solutions is associated with taking into account the visual perception of roads, which is ensured by the correct combination of curvilinear sections of the plan and the longitudinal profile of the route of logging highways. A smooth change in the direction of the road in perspective (and in plan) ensures a gradual movement mode and, therefore, increases the efficiency of the timber road. The aim of the work is to consider the combination of curves in plan and profile and analyze their relationship.

The development of equipment and technology of train operation, railway automation systems and new methods of train driving open the way for further intensification of train operation, reducing the time spent on standard operation procedures. Virtual coupling allows you to reduce a train-to-train interval. Automated schedules of the executed movement record performance of train operation, automate the formation of a train-dispatcher’s reports and delivery of orders to station attendants, allow timely detection of the causes of train delays and take appropriate measures. The points of growth in traffic intensity and volume could be in enhancing the level of intelligence of automation and telemechanics systems. Modern dispatch and electrical centralized systems contain archiving subsystems that store prompt train operation conditions and operator orders. But such data is used only when analyzing emergency situations - there is no systematic analysis of archive information to find hidden patterns and extract knowledge useful for optimizing the transportation process. In this paper, we propose a method for estimating the current train operation load of a railway station, and provide relative criteria for evaluating the actual load and algorithms for determining their numerical values. The analysis of the time series of the proposed criteria obtained for a single station equipped with a relay-processor centralized system is carried out. The analysis indicated a weekly cycle of train operation load of a station with good repeatability. The fact of reducing the speed of trains before the input signal in the through-pass routes with a preset route was revealed. Smoothing out the identified irregularities can positively affect the carrying capacity of a railway section as a whole.

Modern challenges actualize the search for transformation of management and interaction mechanisms and tools for determining and making optimal managerial decisions based on quota (distributed) information and intellectual content, which create conditions for the implementation of a systematic method for solving the problem of creating a large-scale and multifunctional complex of information and intellectual management and interaction systems. In this paper, the principles of building an intersectoral information and intellectual model of integration of information flows of subjects of the interregional level are considered. The construction of the model is based on the principles of information and intellectual interaction in the segment of the information economy of social and marketing cooperation. The components of the model formation methodology are presented. The system of component-methodology assumes concentration in one perimeter of information flows coming from the integrating information systems of subjects of the intersectoral, interregional level, federal regulators and business associations, using the information technology «big data». The model of integration of information flows accumulates and concentrates information knowledge in a single transport and information space and is a quota-based information and intellectual system, the structure of which reflects the coordinated interactions of virtual agents. The subjects of accumulation and concentration of information knowledge are virtual agents (integrating information and intellectual systems) of regulators, subjects and business associations. The creation of such virtual agents is based on the multiagent construction principle. Virtual agents are a new category of software products that operate in information and intellectual environment on behalf of the user. The principles of virtual agent modeling and methodology for constructing the model were used in creating software products «Electronic Service of integrated transport services» and «Multiagent intellectual system for management of transport services in rail-marine traffic», which were registered by the state.

The article proposes a method for selecting parameters based on correlation and regression analysis in order to further include significant variables in the equation of stability of an enterprise of an organizational network. The sample consists of ten businesses and ten hypothetical control points. Three subsystems are accepted for consideration: technical and economic (nine indicators), organizational and legal (seven indicators) and human resources (seven indicators of economic activity of a legal entity). The proposed methodology allows us to justify significant indicators for each of the three subsystems for determining the stability of network elements (enterprises), depending on the overall trend of production capacity: a successfully developing enterprise; a high-performing enterprise; a low-performing one. This method allows us to predict the possible volume of deliveries from enterprises - elements of the network. To achieve this goal, it is proposed to use the apparatus of multivariate analysis, in particular, correlation and regression analysis, which allows us to determine the presence of links and their closeness between factors, as well as the degree of influence on the studied value. The calculations were performed using the “Correlation” and “Regression” tools included in the “Data Analysis” package of the Microsoft Excel program.

With the advancement of photoelectric technology and computer image processing technology, the visual measurement method based on point clouds is gradually applied to the 3D measurement of large workpieces. Point cloud registration is a key step in 3D measurement, and its registration accuracy directly affects the accuracy of 3D measurements. In this study, we designed a novel MPCR-Net for multiple partial point cloud registration networks. First, an ideal point cloud was extracted from the CAD model of the workpiece and was used as the global template. Next, a deep neural network was used to search for the corresponding point groups between each partial point cloud and the global template point cloud. Then, the rigid body transformation matrix was learned according to these correspondence point groups to realize the registration of each partial point cloud. Finally, the iterative closest point algorithm was used to optimize the registration results to obtain a final point cloud model of the workpiece. We conducted point cloud registration experiments on untrained models and actual workpieces, and by comparing them with existing point cloud registration methods, we verified that the MPCR-Net could improve the accuracy and robustness of the 3D point cloud registration.

The biology of aging is focused on the identification of novel pathways that regulate the underlying processes of aging to develop interventions aimed at delaying the onset and progression of chronic diseases to extend lifespan. However, the research on the aging field has been conducted mainly in animal models, yeast, Caenorhabditis elegans and cell culture. Thus, it is unclear to what extent this knowledge is transferable to humans since they might not reflect the complexity of aging in people. Organoid culture is an in vitro 3D cell-culture technology that reproduces the physiological and cellular composition of the tissues and/or organs. This technology is being used in the cancer field to predict the response of a patient-derived tumor to a certain drug or treatment serving as patient stratification and drug-guidance approaches. Modeling aging with patient-derived organoids has a tremendous potential as a preclinical model tool to discover new biomarkers of aging, to predict adverse outcomes during aging and to design personalized approaches for prevention and treatment of aging-related diseases and geriatric syndromes. This could represent a novel approach to study chronological and/or biological aging paving the way to personalized interventions targeting the biology of aging.

Distinguishing circular RNA (circRNA) reads from reads derived from the linear host transcript is a challenging task because of sequence overlap. We developed a computational approach, CiLiQuant, that determines the relative circular and linear abundance of transcripts and gene loci using backsplice and forward splice junction reads generated by existing mapping and circRNA discovery tools.
