Abstrak:

Wabah Pandemi Covid-19 sudah hampir satu tahun terjadi di negara kita tercinta Indonesia. Kemunculan wabah Covid-19 memicu terjadinya berbagai perubahan dalam berbagai aspek kehidupan, baik dari segi aspek sosial, kesehatan, pendidikan, dan lain sebagainya. Selain itu, dengan adanya wabah Covid-19 ini menyebabkan munculnya berbagai kebijakan-kebijakan baru yang disusun oleh pemerintah guna memutus mata rantai penyebaran Covid-19. Termasuk di dalamnya yaitu kebijakan dalam sektor pendidikan. Sesuai dengan kebijakan yang dikeluarkan oleh Kemendikbud, bahwa demi memutus mata rantai penyebaran wabah Covid-19 kegiatan belajar mengajardiberbagai jenjang pendidikan dilaksanakan secara daring (dalam jaringan)dan luring (luar jaringan). Hal ini menjadi sesuatu yang baru dalam dunia pendidikan kita tentunya. Yang mana biasanaya proses belajar mengajar dilakukan secara langsung. Kini, pada saat pandemi covid-19 dengan terpaksa harus dilakukan dengan menggunakan media internet  atau disebut dengan istilah daring (dalam jaringan). Dengan adanya kebijakan tersebut menjadi tantangan tersendiri bagi guru dan siswa sebagai pelaku pendidikan, terutama di daerah-daerah yang minim teknologi dan jaringan internet. Tantangan tersebut berlaku bagi semua guru lembaga pendidikan, tak terkecuali para guru dalam naungan lembaga pendidikan Islam.

Abstract:

The Covid-19 pandemic has occurred in our beloved country Indonesia for almost a year. The emergence of the Covid-19 outbreak triggered various changes in various aspects of life, both in terms of social, health, education, and so on. In addition, the Covid-19 outbreak has led to the emergence of various new policies formulated by the government to break the chain of spreading Covid-19. This includes policies in the education sector. In accordance with the policy issued by the Ministry of Education and Culture, that in order to break the chain of the spread of the Covid-19 outbreak, teaching and learning activities at various levels of education are carried out online (online) and offline (outside the network). This is something new in our world of education. Which is usually the teaching and learning process carried out directly. Now, when the Covid-19 pandemic has to be done with the internet media or referred to as online (in the network). With the existence of this policy, it is a challenge for teachers and students as actors of education, especially in areas that lack technology and internet networks.This challenge applies to all teachers of educational institutions, including teachers under Islamic education institutions. Keywords: Education policy, Islamic education
Nilai-nilai Pendidikan dalam Munasabah Al-Qur’an
Authors: Alfatoni Abdul Hafiz
Published: November 2021

Science Munasabah alqur'an is one of the sciences that play an important role when wanting to interpret the alqur'an, because with it we can know the correlation between verses and hungan between letters. This paper aims for us to be able to know and so that we can understand the understanding of reasonable, procotracted importance of munasabah, various munasabah, urgency of reasonable alqur'an and the values of education that exist in the sense of alqur'an. The research method used is literature research (libray reseach) which is research by collecting various kinds of data obtained from books that are used as data sources. Understanding reasonableness makes it easier for us to recite the Qur'an either with regard to the correlation between verses one with another or correlation between surahs. Munasabah Alqur'an is a correlation between verses, sentences and letters that exist in the Qur'an divided into five kinds, and has a very important role when wanting to understand the meaning in the Qur'an. Musanabah Alqur'a also plays an important role in the obligation in carrying out the teaching and learning process as well as how to improve the ability of teachers in teaching.
The Metaphysical Implications of the Nigerian National Anthem and Pledge
Authors: Oladipupo Sunday Layi
Published: November 2021

This discourse, using the analytical method of philosophical investigation, sets to examine the economic and socio-political implications of the Nigerian national anthem and pledge. In doing this, selected lines from the Nigerian national anthem and pledge were analyzed within the socio-political and developmental process that confronts Nigeria society. The paper, therefore, presents a metaphysical understanding of the life-style of the political elites and civil servants as it is being affected by the wordings of the anthem and pledge. The treatise adopts the meaning of anthem as a song that has special importance for a country, an organization or a particular group of people and is sung on special occasions while the pledge is conceived as a formal promise to be loyal often make by people standing in front of the flag with their right hand on their heart. The paper concludes with a meta-logical argument that the wordings of the anthem and pledge though look ordinary possesses far-reaching implications that could be positive or negative, despite the contemporary realities that suggested that the powers and significance of the words that constitute the anthem and pledge seem to have been lost.

Biobancos: Una estrategia exigente y esencial para la conservación de muestras biológicas
Authors: Martínez Julio César , Briceño Ignacio , Hoyos Alejandra , Gómez Alberto
Published: November 2021

La recolección y conservación de muestras biológicas con fines investigativos es una actividad ligada desde tiempo atrás con la historia y evolución de la ciencia y la medicina; hoy en día, la disponibilidad de bancos de conservación de muestras adecuadamente validadas, está asociada con el desarrollo presente y futuro de la investigación científica.

En general se entiende que un banco de conservación de muestras es un espacio físico que permite mantener en condiciones ideales una serie de muestras biológicas de manera organizada, observando los más altos estándares de calidad, apegados a la normatividad ética y legal establecida para estos casos y cuyo fin es la investigación biomédica tendiente a generar nuevo conocimiento, así como a diversas aplicaciones diagnósticas y terapéuticas.

Los bancos de conservación de muestras constan, más allá de su infraestructura física, de una base de datos que permite conocer en tiempo real y al detalle el estado y condición de cada muestra, además de protocolos y normas claras y perfectamente establecidas para la utilización de las muestras para los proyectos de investigación que las requieran.

La mayoría de los bancos de conservación de muestras nacieron de la necesidad de almacenar muestras biológicas remanentes de alguna investigación biomédica o poblacional, de diferentes campañas de salud, o de muestras recolectadas con propósitos forenses y de criminalística. Posteriormente, con el mejoramiento de las técnicas de conservación de muestras y con el advenimiento de las microtécnicas de análisis molecular, quedó patente la necesidad de institucionalizarlos hasta convertirlos en lo que son hoy, el punto de partida para cualquier proceso investigativo y de generación de nuevo conocimiento, una herramienta científica de primer orden con un potencial de desarrollo virtualmente ilimitado.

Este escrito pretende recrear algunos de los aspectos más importantes del desarrollo de los bioban- cos, así como resaltar su importancia para la consolidación de una cultura investigativa de calidad, seria y sostenida en el tiempo, que redunde en el desarrollo de la comunidad científica en particular y de la sociedad en general

Published: November 2021

Automatic analysis of facial expressions is rapidly becoming an area of intense interest in computer vision and artificial intelligence research communities. In this paper an approach is presented for facial expression recognition of the six basic prototype expressions (i.e., joy, surprise, anger, sadness, fear, and disgust) based on Facial Action Coding System (FACS). The approach utilizes the topological ordering patterns produced by Kohonen Self Organizing Map, in which implemented on expression image sequence for each prototype facial expression. The map will compute the topological relationship between the particular expression sequences, starting from the neutral expression to peak. This method tried to find a topological ordering pattern (shape) for each expression; it will not require any pre-processing tedious work such as normalization. The only requirement is that, image background must be kept constant, also with non-rigid head motion.  The feature extraction phase had been performed by this method, while the classification phase done by especially designed procedures for shape and direction finding to recognize the pattern of the shape, thereafter the type of the expression also backpropagation neural network is implemented for the classification task. An average recognition rate of 88.7% was achieved for six basic expressions, where different databases had been used for the test of the method.

Authors: Dr. Jayakumar.K.  , Dr. Lekha Pillai
Published: November 2021

Adolescence is a crucial period where an individual undergoes significant physical, social, cognitive, behavioural and emotional changes. The covid pandemic which turned the entire world upside down has brought a significant change in the rhythm of life. When the whole world came to a standstill on the declaration of lockdown, the social media got a transition as a coping agent for relieving stress among the teens. The users and usage time of social media increased drastically. An online survey is used for the purpose of collecting data from among the school and college students to understand the changing trends in the social media usage and their impacts on the sleep and sleeping patterns of the teens. The study also analyses the increase in the number of users during the lock down. A sample of 1631 subjects is taken for the conduct of the study. The study reveals that, even though the users and usage time of social media increased considerably, social media usage has no significant impact on sleep.

Close-Up Eye-Asymmetry Visual Metaphor Communicates the Abject: Evidence from Batman and Superman Comics
Authors: Juricevic Igor
Published: November 2021

A distinctive theme of Gothic narratives is the abject. A character that is abject threatens to disrupt boundaries, both personal and societal. As such, the abject character must be rejected or destroyed by society. In this study, I provide evidence that the visual metaphor of Close-Up Eye Asymmetry (CUE-A) communicates the concept of the abject. I compare how often CUE-A is used when depicting Batman compared to Superman in comic books. Overall, I provide evidence that: (1) Batman is Gothic, (2) Batman is more Gothic than Superman, (3) Batman is abject, and (4) Batman is depicted with CUE-A more often than Superman. Taken together, this supports the conclusion that the CUE-A visual metaphor does, in fact, communicate the abject.
Nanoparticles-in-soft microagglomerates as oral colon-specific cancer therapeutic vehicle
Authors: Musa Nafisah , Wui Wong Tin
Published: November 2021

Polymeric nanoparticles can be conjugated with targeting ligand such as folate to elicit oral colon-specific drug delivery to treat colon cancer. Oral chemotherapy can be used as adjuvant, neo-adjuvant, or primary therapy. Nonetheless, oral cancer chemotherapeutics may experience premature drug release at the upper gastrointestinal tract due to the availability of a large specific dissolution surface area of nanoparticles leading to failure in colon cancer targeting. This study designed soft microagglomerates as carrier of nanoparticles to delay drug release. High molecular weight chitosan/pectin with covalent 5-fluorouracil/folate was processed into nanoparticles. Low molecular weight chitosan was spray-dried into nanoparticle aggregation vehicle. The soft agglomerates were produced by blending of nanoparticles and aggregation vehicle in specific weight ratios through vortex method. Adding aggregation vehicle promoted soft agglomeration with nanoparticles deposited onto its surfaces with minimal binary coalescence. Soft agglomerates prepared from 10:18 weight ratio of nanoparticles to nanoparticle aggregation vehicle using 1% chitosan solution concentration reduced the propensity of premature drug release of nanoparticles in the upper gastrointestinal region. Soft agglomerates reduced early drug release of cancer chemotherapeutics and was responsive to intracapsular sodium alginate coat to further sustain drug release. The soft microagglomerates are a viable dosage form in colon-specific drug delivery. Further study will focus on investigating intracapsular-coated soft agglomerates in vivo pharmacokinetics and pharmacodynamics behaviours with respect to local colorectal cancer.
Neuro-fuzzy Architecture for Handover Decision Making in Emerging Heterogeneous Networks
Authors: DRIOUACHE Saida , Naja Najib , Jamali Abdellah
Published: November 2021

In emerging heterogeneous networks, seamless vertical handover is a critical issue. There must be a trade-off between the handover decision delay and accuracy. This paper’s concern is to contribute to reliable vertical handover decision making that makes a trade-off between complexity and effectiveness. So, the paper proposes a neuro-fuzzy architecture that joints the capacity of learning of the artificial neural networks with the power of linguistic interpretation of the fuzzy logic. The architecture can learn from experience how executing a handover to a particular access network affects the quality of service. Simulation results reveal that this architecture is fast, enhances the overall performance and reliability better than the fuzzy logic-based approach.
Local Analogs to High-redshift Galaxies. I. Characterization of Dust Emission and Star Formation History
Authors: Motiño Flores Skarleth M. , Wiklind Tommy , Eufrasio Rafael T.
Published: November 2021

Star-forming dwarf galaxies have properties similar to those expected in high-redshift galaxies. Hence, these local galaxies may provide insights into the evolution of the first galaxies and the physical processes at work. We present a sample of 11 potential local analogs to high-z (LAHz) galaxies. The sample consists of blue compact dwarf galaxies, selected to have spectral energy distributions that fit galaxies at 1.5 < z < 4. We use SOFIA-HAWC+ observations combined with optical and near-infrared data to characterize the dust properties, star formation rate (SFR), and star formation histories (SFHs) of the sample of LAHz galaxies. We employ Bayesian analysis to characterize the dust using two-component blackbody models. Using the Lightning package, we fit the spectral energy distribution of the LAHz galaxies over the far-UV−far-infrared wavelength range and derive the SFH in five time steps up to a look-back time of 13.3 Gyr. Of the 11 LAHz candidates, six galaxies have SFH consistent with no star formation activity at look-back times beyond 1 Gyr. The remaining galaxies show residual levels of star formation at ages ≳1 Gyr, making them less suitable as local analogs. The six young galaxies stand out in our sample by having the lowest gas-phase metallicities. They are characterized by warmer dust, having the highest specific SFR and the highest gas mass fractions. The young age of these six galaxies suggests that merging is less important as a driver of the star formation activity. The six LAHz candidates are promising candidates for studies of the gasdynamics role in driving star formation.
Magnetar Models of Superluminous Supernovae from the Dark Energy Survey: Exploring Redshift Evolution
Authors: Hsu Brian , Hosseinzadeh Griffin , Berger Edo
Published: November 2021

Superluminous supernovae (SLSNe) are luminous transients that can be detected to high redshifts with upcoming optical time-domain surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and Time. An interesting open question is whether the properties of SLSNe evolve through cosmic time. To address this question, in this paper we model the multicolor light curves of all 21 Type I SLSNe from the Dark Energy Survey (DES) with a magnetar spin-down engine, implemented in the Modular Open-Source Fitter for Transients (MOSFiT). With redshifts up to z ≈ 2, this sample includes some of the highest-redshift SLSNe. We find that the DES SLSNe span a similar range of ejecta and magnetar engine parameters as previous samples of mostly lower-redshift SLSNe (spin period P ≈ 0.79–13.61 ms, magnetic field B ≈ (0.03–7.33) × 1014 G, ejecta mass M
ej ≈ 1.54–30.32 M
⊙, and ejecta velocity v
ej ≈ (0.55–1.45) × 104 km s−1). The DES SLSN sample by itself exhibits the previously found negative correlation between M
ej and P, with a pronounced absence of SLSNe with low ejecta mass and rapid spin. Combining our results for the DES SLSNe with 60 previous SLSNe modeled in the same way, we find no evidence for redshift evolution in any of the key physical parameters.
Multiple Stellar Populations at Less-evolved Stages-II: No Evidence of Significant Helium Spread among NGC 1846 Dwarfs
Authors: Li Chengyuan
Published: November 2021

The detection of star-to-star chemical variations in star clusters older than 2 Gyr has changed the traditional view of star clusters as canonical examples of “simple stellar populations” into the so-called “multiple stellar populations” (MPs). Although the significance of MPs seems to correlate with cluster total mass, it seems that the presence of MPs is determined by cluster age. In this article, we use deep photometry from the Hubble Space Telescope to investigate whether the FG-type dwarfs in the ∼1.7 Gyr old cluster NGC 1846, have helium spread. By comparing the observation with the synthetic stellar populations, we estimate a helium spread of ΔY ∼ 0.01 ± 0.01 among the main-sequence stars in NGC 1846. The maximum helium spread would not exceed ΔY ∼ 0.02, depending on the adopted fraction of helium-enriched stars. To mask the color variation caused by such a helium enrichment, a nitrogen enrichment of at least Δ[N/Fe] = 0.8 dex is required, which is excluded by previous analyses of the red-giant branch in this cluster. We find that our result is consistent with the ΔY–mass relationship for Galactic globular clusters. To examine whether or not NGC 1846 harbors MPs, higher photometric accuracy is required. We conclude that under the adopted photometric quality, there is no extreme helium variation among NGC 1846 dwarfs.

Unraveling the geological processes ongoing at Io’s numerous sites of active volcanism requires high spatial resolution to, for example, measure the areal coverage of lava flows or identify the presence of multiple emitting regions within a single volcanic center. In de Kleer et al. (2017) we described observations with the Large Binocular Telescope during an occultation of Io by Europa at ∼6:17 UT on 2015 March 8 and presented a map of the temperature distribution within Loki Patera derived from these data. Here we present emission maps of three other volcanic centers derived from the same observation: Pillan Patera, Kurdalagon Patera, and the vicinity of Ulgen Patera/PV59/N Lerna Regio. The emission is localized by the light curves and resolved into multiple distinct emitting regions in two of the cases. Both Pillan and Kurdalagon Paterae had undergone eruptions in the months prior to our observations, and the location and intensity of the emission are interpreted in the context of the temporal evolution of these eruptions observed from other facilities. The emission from Kurdalagon Patera is resolved into two distinct emitting regions separated by only a few degrees in latitude that were unresolved by Keck observations from the same month.

Introduction: The protozoan parasite Cryptosporidium is one of the principal reasons for childhood diarrhea around the world. This work aimed to differentiate Cryptosporidium species among children suffering from diarrhea in Sharkyia Governorate, Egypt.
Methodology: A total of 97 fecal specimens were taken from children suffering from diarrhea, attending Pediatric Clinics of Zagazig University and Al-Ahrar Hospitals. Full history was taken. Stool samples were examined microscopically using modified Ziehl–Neelsen stain for detection of Cryptosporidium oocysts. To identify Cryptosporidium genotypes, positive samples were then subjected to nested Polymerase chain reaction-restriction fragment length polymorphism targeting Cryptosporidium oocyst wall protein gene.
Results: The overall detection rate was 27.8% (27/97) using modified Ziehl–Neelsen stain staining method. Using nested polymerase chain reaction, the gene was amplified in 85.2% (23/27). Restriction fragment length polymorphism analysis revealed that 65.2% (15/23) were Cryptosporidium hominis, 30.4% (7/23) were Cryptosporidium parvum, and one sample was not typed (4.4%). The significant risk factors associated with Cryptosporidium infection in children were animal contact and residence in rural areas.
Conclusions: Cryptosporidium is a common enteric parasite affecting children in Sharkyia Governorate, Egypt, with the predominance of C. hominis genotype in children.

Aims: In recent years, the internet has been seen as a positive tool that simplify various activities of human life. However, internet use is also seen as negatively impacting the lives of adolescents, especially during the Covid 19 pandemic. This study aimed to explore the life experiences of adolescent girls who became addicted to the internet while learning from home during the Covid 19 pandemic.

Methods: This was a qualitative phenomenology study was conducted in West Java Province, Indonesia. Total sample was 13 adolescent girls which obtained by purposive sampling technique. The inclusion criteria for this study were high school students from high schools; experienced moderate internet addition as evidenced by the result of the Internet Addiction Test (IAT); and able to communicate in Indonesian. Exclusion criteria was participants with communication problem and psychiatric disorders such as depression and schizophrenia. Data were collected through in-depth interviews and analysis was performed using the Collaizzi approach.

Results: Five themes were identified in this study: constant use of the internet due to boredom, bad mood, and curiosity; health issues due to internet use; easily influenced by internet contents; tend to forget learning materials and lazy to learn; and parental supervision.

Conclusion: Adolescent girls with internet addiction have a complex life as they are easily influenced by what they see on the internet. In addition, these girls also experience various health problems. The results of this study can provide information to the public and health workers about the importance of monitoring the use of the internet among adolescents. Controlling the use of the internet is still necessary for internet use and is good and in accordance with the needs and based on the development of adolescents.

Introduction : Malgré plusieurs initiatives du ministère de la Santé marocain pour protéger le droit des migrants à accéder aux services de santé, la vaccination des enfants migrants demeure un problème de santé publique. Objectif de l’étude : L’objectif de cette étude était de mesurer la couverture vaccinale et d’identifier les facteurs associés à la non-complétude vaccinale des enfants migrants subsahariens de moins de 5 ans dans la ville de Casablanca. Méthodes : À partir d’une étude transversale à visée analytique, un échantillonnage en boule de neige a été réalisé et un questionnaire a été administré aux mères migrantes subsahariennes des enfants de moins de 5 ans. Les résultats des analyses descriptives et le test de Chi 2 ont permis d’élaborer un modèle prédictif à travers la régression logistique multivariée. Les informations collectées incluaient les caractéristiques sociodémographiques, les facteurs liés à l’accessibilité au service de vaccination, les connaissances et perception des mères sur la vaccination. Résultats : Environ 57,0 % des enfants migrants subsahariens de moins de 5 ans ont été incomplètement ou non vaccinés. Les facteurs associés significativement au statut vaccinal après l’analyse multivariée étaient le niveau d’études des mères (4,895 [1,907-12,562]), le statut professionnel (0,411 [0,206-0,821]), la connaissance des avantages de la vaccination (0,035 [0,004-0,309]) et du calendrier vaccinal (6,854 [3,172-14,813]), le temps d’attente (0,115 [0,051-0,261]), les barrières administratives (7,572 [2,004-28,617]) et psychologiques (0,086 [0,043-0,170]). Conclusion : Le statut vaccinal des enfants migrants de moins de 5 ans de la ville de Casablanca demeure un problème de santé publique, et nécessite une meilleure prise en charge afin d’améliorer la situation vaccinale de cette population vulnérable.

Partial balanced incomplete block designs have a wide range of applications in many areas. Such designs provide advantages over fully balanced incomplete block designs as they allow for designs with a low number of blocks and different associations. This paper introduces a class of partially balanced incomplete designs. We call it partially balanced network designs (PBNDs). The fundamentals and properties of PBNDs are studied. We are concerned with modeling PBNDs as graph designs. Some direct constructions of small PBNDs and generalized PBNDs are introduced. Besides that, we show that our modeling yields an effective utilization of PNBDs in constructing graph codes. Here, we are interested in constructing graph codes from bipartite graphs. We have proved that these codes have good characteristics for error detection and correction. In the end, the paper introduces a novel technique for generating new codes from already constructed codes. This technique results in increasing the ability to correct errors.

The paper is concerned with a class of stochastic differential equations in infinite dimensional Hilbert space with random coefficients driven by Teugels martingales which are more general processes and the corresponding optimal control problems. Here Teugels martingales are a family of pairwise strongly orthonormal martingales associated with Lévy processes (see Nualart and Schoutens [21]). There are three major ingredients. The first is to prove the existence and uniqueness of the solutions by continuous dependence theorem of solutions combining with the parameter extension method. The second is to establish the stochastic maximum principle and verification theorem for our optimal control problem by the classic convex variation method and dual techniques. The third is to represent an example of a Cauchy problem for a controlled stochastic partial differential equation driven by Teugels martingales which our theoretical results can solve.

The essential aim of the current work is to enhance the application aspects of Pawlak rough sets. Using the notion of a j-neighborhood space and the related concept of θβ-open sets, different methods for generalizing Pawlak rough sets are proposed and their characteristics will be examined. Moreover, in the context of ideal notion, novel generalizations of Pawlak's models and some of their generalizations are presented. Comparisons between the suggested methods and the previous approximations are calculated. Finally, an application from real-life problems is proposed to explain the importance of our decision-making methods.

The sympathetic nervous system (SNS) is an important regulator of immune cell function during homeostasis and states of inflammation. Recently, the SNS has been found to bolster tumor growth and impair the development of antitumor immunity. However, it is unclear whether the SNS can modulate APC function. Here, we investigated the effects of SNS signaling in murine monocyte-derived macrophages (moMФ) and dendritic cells (DCs) and further combined the nonspecific β-blocker propranolol with a peptide cancer vaccine for the treatment of melanoma in mice. We report that norepinephrine treatment dramatically altered moMФ cytokine production, whereas DCs were unresponsive to norepinephrine and critically lack β2-adrenergic receptor expression. In addition, we show that propranolol plus cancer vaccine enhanced peripheral DC maturation, increased the intratumor proportion of effector CD8+ T cells, and decreased the presence of intratumor PD-L1+ myeloid-derived suppressor cells. Furthermore, this combination dramatically reduced tumor growth compared with vaccination alone. Taken together, these results offer insights into the cell-specific manner by which the SNS regulates the APC immune compartment and provide strong support for the use of propranolol in combination with cancer vaccines to improve patient response rates and survival.
Morphofunctional, viability and antioxidant system alterations on rat primary testicular cells exposed to simulated microgravity
Authors: Bonetto Valentina , Scarabelli Linda , Masini Maria Angela
Published: November 2021

This study focused on effects induced by Short-term Simulated Microgravity (SMG) condition on primary cell culture from pre-pubertal Wistar rats testis. Cells were analyzed for cytoskeletal and Sex Hormone Binding Globulin (SHBG/ABP) changes by immunofluorescence technique, for antioxidant system exploiting RT-PCR and cell viability. Cells were cultured for 6 and 24h on a three-dimensional clinostat, Random Positioning Machine (RPM). At the end of each experiment, once stopped the RPM rotation, cells were either fixed in paraformaldehyde or lysed and RNA extracted. In cells exposed to SMG the cytoskeleton became disorganized, microtubules fragmented and SHBG was already undetectable after 6h of treatment. Moreover, various antioxidant systems significantly increased after 24h of SMG exposure. Initially, SMG seemed to disturb antioxidant protection strategies allowing the testes to support sperm production, thus generating an aging-like state of oxidative stress. Studies on changes induced by short-term altered gravity conditions, carried out in real microgravity, could give more information on steroidogenesis and germ cell differentiation within the testis exposed to this condition and confirm the validity of simulation approach.
