Authors:   Fundación Universitaria Iberoamericana (Brasil), Sant`Anna Macie Mónica Pires , Maciel Pereira José Antonio ,   Fundación Universitaria Iberoamericana (Brasil)
Published: June 2021

Este artículo es un primer paso hacia la construcción de un modelo teórico personalizado que se aplica en la industria marítima para la solución de los conflictos organizativos de una empresa de servicios de apoyo marítimo a través de una herramienta sistémica. Este modelo se deriva de la técnica de resolución de conflictos autocomputada llamada Constelación Organizacional Sistémica desarrollada inicialmente por Bert Hellinger. Su redacción se apoyó en una bibliografía teórica sobre el uso de esta técnica, compilada entre 2014 y 2020 a partir del banco electrónico existente de literatura científica Google Scholar con el uso de sintaxis específica. Se utilizó el método de análisis de contenido, basado en una matriz de Constelaciones Familiares, para la intersección de trabajos académicos teóricos sobre tipos de Constelaciones y sobre Empresas de Apoyo Marítimo para identificar las características funcionales necesarias en una empresa del sector y su idoneidad para los roles existentes. de los participantes involucrados directa o indirectamente en el proceso de una Constelación Organizacional. Como resultado, la construcción del modelo sigue siendo totalmente empírica, y su validez se discute con el uso de grupos de discusión y su empleabilidad en la empresa en esta área. En conclusión, se entiende que se trata de un modelo pionero, robusto y personalizado, y que está listo para ser probado en alguna empresa de apoyo marítimo para la evaluación y verificación de los ajustes necesarios.

Las intervenciones basadas en Mindfulnesscada vez son más utilizadas para intervenir en estrés, ansiedad o depresión; sin embargo, para trastorno mental grave aún se requiere de más investigación. El objetivo de este estudio es comprobar la eficacia de un programa de Mindfulness adaptado para enfermedad mental, sobre la ansiedad, depresión y calidad de vida de personas diagnosticadas de trastorno mental grave. Para comprobar su eficacia, se reclutó una muestra de 26 usuarios del Centro de Rehabilitación Psicosocial Padre Menni de Torrelavega, divididos en 2 grupos, 13 en grupo control, y 13 en grupo experimental. Se procedió al estudio recogiendo medidas en dos momentos diferentes, pretest y postest, a través de los instrumentos STAI, BDI y WHOQOL-BREF para medir ansiedad, depresión y calidad de vida, respectivamente. Se comprobó que la muestra de ambos grupos pertenecía a la misma población, y através del análisis de varianza con medidas repetidas ANOVA, los resultados demostraron pequeñas diferencias estadísticamente significativas en ansiedad/rasgo y depresión, que sin embargo no fue así en la medición pre y post de las variables ansiedad/estado y calidad de vida, concluyendo finalmente que el programa de intervención atendió de manera parcial al objetivo de reducir la sintomatología más común de la enfermedad mental grave.
حقِّ الزوجة في مال الزوج المكتسب بعد الزواج - دراسة فقهية
Authors: Abdelgayed Ahmed Fathi Ramadan
Published: June 2021

At present, there have been some calls for the wife to share the property acquired by the husband during the marriage period, claiming that these efforts are the result of the effort of both spouses, whether through the woman's work in the home, where that husband helped to work quietly outside the home, or through the couple's work outside the home. In this research, I discussed the evidence of the wife's participation in all the property acquired by the husband.

In this research, it concluded that the spouses in matters of property, wealth, income and conduct are completely independent, that the marriage contract does not give rise to any right to the other's property or income other than Islamic rights,

The financial dealings between spouses were governed by the Islamic provisions on financial transactions, and if the spouses disagreed in the ownership of something, each one must provide evidence of the validity of his claim.

Published: June 2021

Al-ʿUrf (customary law) is considered among the disputed jurisprudential evidence between the Uṣulī scholar. However, it is not hidden from majority of the scholar that custom has legal impact and that custom is authoritative, besides, it is well-known that custom is one of the major legal maxims according to the Shafiʿīs, and there is no doubt that resorting to custom is based on the realization of public interests and sometimes of a class or sect of society, given its legislative framework and its significant divisions among the fundamentalists.Therefore, under the light of jurisprudential evidence, this research aims for a sound jurisprudential computation of the shared properties between the spouses by examining the term and defining its concept, and does one of the spouse has the right to demand some money when the marriage discontinues, or is it permissible to request in the event of a divorce or death between them with something from the husband’s private gain as a partner in it? If the Sharīʿah does not allow the will in a person’s life by more than a third, which is his money and his dependents’, does it is permissible for the spouse to demand half of the properties upon divorce or death, while half is more than one-third, and for what extend will the damage or loss occur in the half division?  By that, this research has followed the descriptive inductive analytical approach to arrive into its findings.

MANAGING TERRORISM IN AFRICA
Authors: Bussotti Luca
Published: June 2021

Despite the different interpretations on the origins and a possible way to manage the Islamic terrorism in Africa, a thing is clear: this phenomenon gained importance in the last few years. Data of ACLED show that in 2015 Africa registered 381 attacks, which resulted in 1.394 fatalities; five years later the number increased to 7.108 attacks and 12.519 fatalities (Mroszczyk & Abrahms, 2021). It is not difficult to deduce that Islamic terrorism was not managed appropriately by the African States. It is the case of countries as Nigeria with Boko Haram, Somalia with Al-Shabaab, Mozambique with Ansar-al-Sunna, with links with the Central African Province of the Islamic State.

Authors: Egerová Dana , Rotenbornová Lucie
Published: June 2021

Workplace conflict is regarded as a naturally and unavoidably occurring phenomenon in today's organisations. To identify the causes of workplace conflict it is critically important to determine appropriate conflict management strategies and effectively manage conflict. The purpose of this study was to explore causes of interpersonal conflicts between managers and employees and the conflict management styles used to handle these conflicts. A qualitative approach including thematic analysis and content analysis was employed. The thematic analysis was carried out to explore the themes concerning causes of conflicts between managers and employees. The content analysis was used to identify the conflict management styles. The data for both analyses included 47 individual written assignments describing conflict situations between managers and employees. Four general themes including poor management, manager personality, poor communication and differences in views emerged from the thematic analysis. Each theme also encompassed a number of subthemes. The findings of the content analysis showed that fight was the most adopted style used by both male and female managers. The findings also revealed that three styles emerge as the most frequently adopted by employees including avoidance, adaptation, and collaboration. The practical implications and limitations of this study are discussed.
Keywords: causes of conflict, conflict management styles, gender, qualitative analysis, workplace conflict

Published: June 2021

Health care systems are affected by sudden increases in demand that can be generated by factors such as natural disasters, terrorist attacks, epidemics, among others. Patient demand can be divided between scheduled and walk-in and, in pandemic scenarios, both of them must be managed in order to avoid higher patient waiting times or number in queue. A discrete event simulation model is proposed in order to evaluate critical indicators like: patient waiting times, number in queue, resource utilization (doctors), using four different patient schedule appointment rules. In this study it was also considered patients impunctuality, walk-in patients and no-show in different scenarios. The best schedule appointment rules for each demand scenario were evaluated. After comparing six performance indicators, four schedule appointment rules in nine different scenarios it was found that the most known scheduling rule had the lowest queue sizes at scenarios with low or no walk-in patients, whereas, as the unpredictability of the scenarios rose, other rules outperformed it. It was also presented to exist an inverse relation between queue size and the physician idle time.
Keywords: discrete event simulation, idle-time, queue management, appointment scheduling, health care.

Acute graft-versus-host disease (aGvHD) remains a major threat to successful outcome following allogeneic hematopoietic cell transplantation though advances in prophylaxis and supportive care have been made. The aim of this study is to test whether the incidence and mortality of aGvHD have decreased over time. 102,557 patients with a median age of 47.6 years and with malignancies after first allogeneic sibling or unrelated donor (URD) transplant were studied in the following periods: 1990-1995, 1996-2000, 2001-2005, 2006-2010 and 2011-2015. Findings: 100-day incidences of aGvHD grades II-IV decreased from 40% to 38%, 32%, 29% and 28%, respectively, over calendar time (P<0.001). In multivariate analysis URD, not in complete remission (CR) at transplant or untreated, and female donor for male recipient were factors associated with increased risk whereas the use of ATG/alemtuzumab decreased aGvHD incidence. Median follow-up was 214, 169, 127, 81 and 30 months, respectively, for the periods analyzed. Three-year-survival after aGvHD grades II-IV increased significantly from 38% to 40%, 43%, 44%, and 45%, respectively. In multivariate analysis URD, not in CR at transplant, peripheral blood as stem cell source, female donor for male recipient, and the use of ATG/alemtuzumab were associated with increased mortality whereas reduced-intensity conditioning was linked to lower mortality. Mortality increased with increasing patient age but decreased in the recent cohorts. Our analysis demonstrates that aGvHD has decreased over recent decades and also that the survival rates of patients affected with aGvHD has improved.

Published: June 2021

Results of the evaluation on bioefficacy of three indigenous plant extracts for toxicity and residual effects against the pulse beetle, Callosobruchus chinensis L. (Bruchidae: Coleoptera) showed that the plant extracts had toxic and residual effects for controlling pulse beetle. Mortality and residual effects were statistically different among the plant extracts and doses applied. Neem extract showed the highest adult mortality (36.78%) whereas eucalyptus extract showed the lowest (22.75%). The order of the toxicity of three plant extracts was found as neem > custard apple > eucalyptus. Mortality was found directly proportional to the hour after treatments which increased with the progress of time. Between two solvents, acetone solvent possessed the highest toxicity (mortality 32.95%) but methanol showed the lowest toxicity (mortality 30.56%). The residual toxicity was evaluated on the basis of egg laid, adult emergence, seed infestation and weight loss caused by the insect. The highest residual toxicity was found in neem extract with acetone while the lowest in eucalyptus extract with acetone. Neem extract with acetone and custard apple extract with methanol solvent were found effective to toxic and residual effects against pulse beetle of three plant extracts applied.

We prove that if {un}n≥ 0 is a nondegenerate Lucas sequence, then there are only finitely many effectively computable positive integers n such that |un|=f(m!), where f is either the sum-of-divisors function, or the sum-of-proper-divisors function, or the Euler phi function. We also give a theorem that holds for a more general class of integer sequences and illustrate our results through a few specific examples. This paper is motivated by a previous work of Iannucci and Luca who addressed the above problem with Catalan numbers and the sum-of-proper-divisors function.

The purpose of this paper is to prove the following result. Let n≥3 be some fixed integer and let R be a (n+1)!2n-2-torsion free semiprime unital ring. Suppose there exists an additive mapping D: R→ R satisfying the relation for all x ∈ R. In this case D is a derivation. The history of this result goes back to a classical result of Herstein, which states that any Jordan derivation on a 2-torsion free prime ring is a derivation.

Published: June 2021

Empleando el novedoso método pirólisis de aerosol en llama (FSP) se sintetizó por primera vez un biovidrio de fosfato de calcio en el sistema P2O5-CaO-Na2O. Las muestras obtenidas se caracterizaron mediante difracción de rayos X (DRX) y espectroscopía infrarroja de reflectancia difusa  (DRIFTS), sirviendo esta última para seguir la cinética de biomineralización in-vitro durante 15 días en fluido corporal simulado (SBF). Mediante DRX se validó la naturaleza amorfa del biovidrio exhibiendo la fase whitlockita. El análisis DRIFTS reveló las bandas características de los grupos fosfatos en un rango de alrededor de los 500 a 1400 cm-1. Respectivamente, la evolución de las bandas de fosfatos en las muestras sumergidas en SBF indican la formación de apatita, proceso que siguió una cinética de pseudo- primer-orden de Lagergren.

Using the novel flame aerosol pyrolysis method (FSP), a calcium phosphate bioglass was synthesized for the first time in the P2O5-CaO-Na2O. The samples obtained were characterized by X-ray diffraction(XRD) and diffuse reflectance infrared spectroscopy (DRIFTS), the latter serving to follow in-vitro biomineralization kinetics for 15 days in simulated body fluid (SBF). Using XRD, the amorphous nature of the bioglass was validated by exhibiting the whitlockite phase.The DRIFTS analysis revealed the characteristic bands of the phosphate groups in a range of about 500 to 1400 cm-1. Respectively, the evolution of the phosphate bands in the samples submerged in SBF indicate the formation of apatite, a process that followed a pseudo-first-order Lagergren kinetics.

Published: June 2021

An analysis of the experience of financial support for the formation and development of critical infrastructure in foreign countries has been carried out. It is noted that the critical infrastructure provides the necessary services in various fields to maintain their smooth state. It is determined that its financing is carried out by attracting resources from various sources, which include public, private and mixed (public-private) projects, as well as funds of financial intermediaries. Mechanisms for financing critical infrastructure used in foreign countries are revealed. Considerable attention is paid to the issues of regulation operations of financial support for the functional capacity of critical infrastructure. Issues of financial risks of critical services and the factors that affect them are covered. It is noted that to limit them, portfolio approaches have been introduced to place the mobilized resource in infrastructure projects, as well as measures of state and non-state support are applied (guarantees, insurance programs, granting preferences, etc.). Particular attention is paid to the impact of the Covid-19 pandemic on the application of financial support for critical infrastructure upgrades and provision of critical services. It is noted that such changes require a significant increase in costs for increasing investment activities in infrastructure, support for private investment, improving the attraction of funds of specialized financial companies to invest in infrastructure projects. The mechanisms implemented in order to solve such problems are identified. Recommendations are given to take into account the experience of foreign countries in the application of measures to finance critical infrastructure in Ukraine. Keywords: critical infrastructure, critical services, infrastructure financing, infrastructure financing risks, public-private partnership, debt instruments, guarantees and benefits for infrastructure financing.

Authors:   Simon Kuznets Kharkiv National University of Economics, NAIDENKO Oleksii
Published: June 2021

Approaches to defining the essence of family businesses in foreign countries are considered and the main requirements for their creation are determined. It is determined that family business in foreign countries is mostly carried out in farming. The world family business is characterized by two features. First of all, the preservation of a huge number of small and medium enterprises created by family members. The second feature is the presence of huge family corporations and holdings with a world name and age history, which are inherited 3-6 times. Approaches to the regulation of family businesses in the Czech Republic, Hungary and Romania are analyzed. Foreign experience proves that family businesses can be created both in the form of commercial enterprises and in the form of a legal entity, which allows companies to choose the rules of their own activities; an automatic registration procedure is applied, which reduces time costs; the law defines the list of persons who may belong to family members; joint and several liability of family members under the terms of the contract is applied, which strengthens the liability of all family members for the results of activities; There is a distribution of profits depending on the amount of contributions of each family member, which creates the interest of all persons in increasing the profits of the enterprise. Draft legislative acts were considered, which provided for the introduction of family businesses taxation or regulation of their economic activities. The advantages and disadvantages of such bills are substantiated. The existing system of taxation of family farms within the single tax is analyzed (group 4). Recommendations on the possible introduction of family business taxation in Ukraine as part of the simplified taxation system are substantiated. The risks of applying family business taxation for the state and family businesses are highlighted.

Published: June 2021

The existing publicly available programs for the design of unmanned aerial vehicle (UAV) flights assume an initial level of personnel training and do not provide for a detailed study of the aerial pho-tography project (APP) in terms of photogrammetric and visual (photographic) quality of photographic materials, requirements of regulatory documents for the accuracy of the final product. In order to achieve the topographic quality of the APP with UAV, it is necessary to take into account a number of its features. The paper considers the issues of determining the optimal duration of the aerial photog-raphy day and the effective image format when using interchangeable lenses. It also provides the rec-ommended procedure for calculating the parameters of the topographic APP, taking into account the data of the exposure triangle "shutter speed - aperture - photosensitivity (ISO)", requirements for the maximum quality and theoretical resolution of the "lens - digital image" system. The technique of de-termining the position of high-rise objects relative to the boundaries of the depth of field (DOF) at giv-en exposure parameters of the camera and the possibility of their correction is described. Based on the theoretical provisions, the author has developed a program that allows it possible to carry out the com-prehensive design of aerial photography works with UAVs, including consumer cameras to obtain re-sults of topographic quality. According to the results of the carried out research, it was concluded that an iterative approach to the design of APP parameters is necessary based on the data on shoot location, the customer's requirements for accuracy, the characteristics of the UAV, and the used photographic equipment.

The article analyzes the map data source storage in analog and digital form by means of various funds, agencies, organizations, libraries, private collections on the basis of an integration method. A conceptual integration model for the map material storage based on a hierarchical, tree-like topological structure has been developed. The topology of the map material storage was built and a conceptual model was presented. The defects in the creation and dissemination of materials (data), weakening the overall quality of the model, are noted. The prospects for the development of the industry of geodesy, cartography and spatial data, which will have a beneficial effect on the quality of the presented model, are noted. The proposed model of storage of cartographic materials demonstrates, for the most part, the Russian experience. It is concluded that against the background of the growing volume of spatial information about terrain feature, structuring and storing information, including in the form of map materials, is an important aspect in the effective use of data for making different levels of decisions.

The article discusses the possibility of using mathematical modeling to assess the state of the main technological equipment of the chamber for receiving and launching cleaning and diagnostic tools (PPC) to predict possible changes in the position of equipment elements from the corresponding design values. Based on the completed planned cycles of geodetic observations, based on the measurement results, calculations were made to build predictive mathematical models for the subsequent study of the deformation processes of the main technological equipment of the chamber for receiving and launching cleaning and diagnostic tools. The mechanisms of sequential processing of the measurement results for the sample belonging to the law of normal distribution by an approximate method and fur-ther data preparation by forming statistically homogeneous groups of process implementations in order to build predictive mathematical models are shown. According to the prediction results, deformation marks were identified, for which the process of deformation proceeds with a higher rate of upsetting in comparison with other marks. Recommendations for further geodetic observations are proposed.

The article considers the accuracy of floor models creation in large span structures with the use of unmanned aerial vehicles for the purpose of determining their deformations. There were performed 4 aero shootings of Water Sports Palace in Dushambe, which were processed by SIFT algorithm. Syn-chronically with the UAV shooting there was performed the measurements on deformation marks within the frames of geodetic monitoring. There was performed the statistical analysis of models accu-racy by method of interpolation of spherical function, which showed that 80% of points has devia-tions less than 30 mm, and the rest 20% has deviations up to 80 mm. The use of collocation method for smoothing optimal filtering allowed to decrease the differences between settlement surfaces ob-tained by geodetic measurement and UAV shooting up to 26mm., which is 10 % of acceptable devia-tions of this object.

This article is about the importance of collaboration in the development of teacher professionalism, and we have asked the research question: How can group collaboration between vocational education and training (VET) students contribute to the development of their teacher professionalism? The data basis is interviews with ten VET students in practical pedagogical education for vocational teachers that we conducted in the winter of 2020. In addition, we studied all internship documents that the ten students produced during the internship period. The students are in practical training at their own school with their own students and collaborate with each other to strengthen their own teacher role. We have applied Dale’s (1989, 1993, 2001) theory of teacher professionalism. To analyse collaboration, we used the theories of Hegel (1999), Honneth (2008, 2009), Barth (1994) and De Hei et al. (2018). We found that this internship made it possible for students to talk and reflect on didactic questions related to Dale’s three areas of expertise.

Improving a drug delivery system is critical to treat central nervous system disorders. Here we studied an innovative approach based on implantation of a wireless-powered cell-based device in mice. This device, coupling biologic material and electronics, is the first of its kind. The advantage of this technology is its ability to control the secretion of a therapeutic molecule and to switch the classical permanent delivery to activation on demand. In diseases with relapsing-remitting phases such as multiple sclerosis, such activation could be selectively achieved in relapsing phases. However, the safety (tolerance to biomaterials and surgical procedure) of such a clinical device needs to be verified. Therefore, the development of tools to assess the biocompatibility of the system in animal models is an essential step. We present the development of this new therapeutic approach, the challenges we encountered during the different steps of its development (such as cell loading in the chamber, surgery protocol for subcutaneous implantation of the device) and the tools we used to evaluate cell viability and biocompatibility of the device.

Patients who sustain peripheral nerve injuries (PNIs) are often left with debilitating sensory and motor loss. Presently, there is a lack of clinically available therapeutics that can be given as an adjunct to surgical repair to enhance the regenerative process. Insulin-like growth factor-1 (IGF-1) represents a promising therapeutic target to meet this need, given its well-described trophic and anti-apoptotic effects on neurons, Schwann cells (SCs), and myocytes. Here, we review the literature regarding the therapeutic potential of IGF-1 in PNI. We appraised the literature for the various approaches of IGF-1 administration with the aim of identifying which are the most promising in offering a pathway toward clinical application. We also sought to determine the optimal reported dosage ranges for the various delivery approaches that have been investigated.

Ulcers are a lower-extremity complication of diabetes with high recurrence rates. Oxidative stress has been identified as a key factor in impaired diabetic wound healing. Hyperglycemia induces an accumulation of intracellular reactive oxygen species (ROS) and advanced glycation end products, activation of intracellular metabolic pathways, such as the polyol pathway, and PKC signaling leading to suppression of antioxidant enzymes and compounds. Excessive and uncontrolled oxidative stress impairs the function of cells involved in the wound healing process, resulting in chronic non-healing wounds. Given the central role of oxidative stress in the pathology of diabetic ulcers, we performed a comprehensive review on the mechanism of oxidative stress in diabetic wound healing, focusing on the progress of antioxidant therapeutics. We summarize the antioxidant therapies proposed in the past 5 years for use in diabetic wound healing, including Nrf2- and NFκB-pathway-related antioxidant therapy, vitamins, enzymes, hormones, medicinal plants, and biological materials.

Pregnancy rates in ewes are markedly low after cervical insemination with frozen-thawed sperm. Sensitivity of ram sperm to freeze-thawing is related to the lipid composition of the membrane, particularly to its low sterol content. Recently, we proved that sterol content of ram sperm can be increased by treatment with methyl-β-cyclodextrin-sterol complexes and we provided mechanistic based evidence on the differential behavior of cholesterol and desmosterol in the ram sperm membrane. In the present study, we evaluated the role of increasing cholesterol and desmosterol content of ram sperm before cryopreservation, on the extent and distribution of sterols, cryocapacitation status, acrosome integrity, DNA damage associated with apoptosis and fertility competence in vitro and in vivo of post-thawed sperm. After freeze-thawing, similar levels of sterol content were evidenced in control sperm cells and in those pre-incubated with either cholesterol or desmosterol. Still, moderately higher levels of sterols were registered in treated sperm compared to the control, indicating no physiological excess of sterols after thawing or sterol losses that exceed the control. Live cell imaging of fluorescent cholesterol evidenced the presence of sperm sub-populations differentially affected by freeze-thawing. Similar unimodal frequency profiles were observed between sterol-enriched groups, while the control exhibited a sub-population of sperm compatible with low sterol content. Tyrosine phosphorylation was significantly lower when ram sperm incorporated cholesterol compared to the control. No difference in this capacitation parameter was found between the latter and desmosterol-enriched sperm. The percentage of sperm with damaged acrosomes post-thawing, assessed by a fluorescent lectin, was reduced in sperm that incorporated sterols before freezing, irrespective of the sterol class. These results suggest that sterols exert a stabilizing effect on the acrosome. No differences were found in levels of apoptotic DNA fragmentation among experimental groups. As to fertility trials, desmosterol-enriched sperm gave rise to higher rates of in vitro activated oocytes by heterologous fertilization and to significantly lower pregnancy loss in vivo. Our research provides new insights on sterol incorporation into ram sperm prior to cryopreservation, in particular on the additional benefit of incorporating desmosterol as a strategy to improve fertility outcome.
Actin Dynamics at the T Cell Synapse as Revealed by Immune-Related Actinopathies

Published: June 2021

The actin cytoskeleton is composed of dynamic filament networks that build adaptable local architectures to sustain nearly all cellular activities in response to a myriad of stimuli. Although the function of numerous players that tune actin remodeling is known, the coordinated molecular orchestration of the actin cytoskeleton to guide cellular decisions is still ill defined. T lymphocytes provide a prototypical example of how a complex program of actin cytoskeleton remodeling sustains the spatio-temporal control of key cellular activities, namely antigen scanning and sensing, as well as polarized delivery of effector molecules, via the immunological synapse. We here review the unique knowledge on actin dynamics at the T lymphocyte synapse gained through the study of primary immunodeficiences caused by mutations in genes encoding actin regulatory proteins. Beyond the specific roles of individual actin remodelers, we further develop the view that these operate in a coordinated manner and are an integral part of multiple signaling pathways in T lymphocytes.

Published: June 2021

Lysine glutarylation (Kglu) is a newly discovered post-translational modification (PTM), which is considered to be reversible, dynamic, and conserved in prokaryotes and eukaryotes. Recent developments in the identification of Kglu by mass spectrometry have shown that Kglu is mainly involved in the regulation of metabolism, oxidative damage, chromatin dynamics and is associated with various diseases. In this review, we firstly summarize the development history of glutarylation, the biochemical processes of glutarylation and deglutarylation. Then we focus on the pathophysiological functions such as glutaric acidemia 1, asthenospermia, etc. Finally, the current computational tools for predicting glutarylation sites are discussed. These emerging findings point to new functions for lysine glutarylation and related enzymes, and also highlight the mechanisms by which glutarylation regulates diverse cellular processes.
