Published: January 2024

Intolerance of positive airway pressure therapy for obstructive sleep apnea is common. Upper airway muscle therapies show promise as alternative treatments. The didgeridoo, which is a musical instrument, can be used for upper airway muscle training. Our goal was to develop a group-based didgeridoo training program for obstructive sleep apnea. We conducted a proof-of-concept single-arm study consisting of a structured didgeridoo training regimen. We surveyed patients at a large medical facility about their interest in the program. We developed and tested a manual of procedures for conducting a 4-session group program conducted over 8 weeks that instructed participants on use of the Medical Didgeridoo. We also refined procedures for baseline and 4-month follow-up assessments, which included measures of daytime sleepiness and apnea–hypopnea index. Interviews were conducted at follow-up to obtain feedback about the program. Of the 56 survey respondents, 67% reported difficulty with positive airway pressure, expressed interest in participating in a structured upper airway muscle training program, and indicated that they would be willing to practice exercises for 30 min per day. After in-depth screening of 15 patients, we recruited five patients to participate in the structured training program; all five completed the program and were able to learn to play basic sounds on the provided instrument, and four stated they would continue to play the Medical Didgeridoo after completion of the program. Given the significant level of interest and excellent participation in the didgeridoo training program, it may be feasible to conduct a large-scale study to assess treatment response.
Morphological and molecular characterisation of Helicotylenchus zengchengensis n. sp. (Nematoda: Hoplolaimidae) from China, with a review on Helicotylenchus species in China
Authors: Chen Yan , Lu Yang , Xie Hui , Xu Chunling
Published: January 2024

Helicotylenchus comprises a significant group of plant-parasitic nematodes that primarily feed on plant roots. This study focuses on the description of a newly discovered species, Helicotylenchus zenchengensis n. sp., from China. The distinguishing characteristic of this species, as observed under a microscope, is the absence of head annulation. The stylet, measuring between 23.8 and 29.3 μm, exhibits anteriorly flattened or indented stylet knobs. The elongated tail has a c value ranging from 15.8 to 22.6 and a c’ value between 1.9 and 2.4. It bears 15 to 18 tail annuli, presenting a conical shape with projections. The phasmids are located at the 4th to 10th body annulations posterior to the anus, while no males were observed. Three phylogenetic trees were constructed to determine the evolutionary relationships using the 18S rRNA, ITS, and 28S D2-D3 expansion segments of the newly discovered species and related Helicotylenchus sequences obtained from the database. Based on the ITS sequences, a phylogenetic tree revealed that H. zenchengensis n. sp. clustered with H. cuspicaudatus. However, it was distinguished from H. cuspicaudatus when examining the 18S and 28S rRNA sequences and morphological characteristics. Additionally, comprehensive and diagnostic tables for all known species of Helicotylenchus in China are provided for reference.
Bayesian joint inversion of seismic and electromagnetic data for reservoir lithofluid facies, including geophysical and petrophysical rock properties

Published: January 2024

A Bayesian approach is developed to estimate lithofluid facies and other rock properties conditioned on seismic and electromagnetic data for reservoir characterization. Prior distributions are assumed to be facies-related Gaussian modes of geophysical rock properties directly acquired or converted from petrophysical properties by calibrated rock-physics modeling. An original generalization includes two distributions in the same marginalization integral, analytically solved under a linearized Gaussian assumption to provide a facies model likelihood conditioned on geophysical data. Because computing this probability for all possible facies configurations may be impractical, a Markov chain Monte Carlo algorithm efficiently samples models to provide a full posterior distribution. The linearized Gaussian approach allows the computation of the conditional distributions of geophysical and petrophysical rock properties by applying local deterministic inversions over the many sampled facies models. The inversion uses simulated geophysical data from a 1D synthetic model based on the geologic scenario and a well from a selected marine oil field. Two other wells from the same reservoir are used to gather prior distributions. Data from the well, calibration of the rock-physics modeling, and facies matching between the priors and the synthetic model are presented and discussed. Numerical tests validate nonlinear forward-modeling adaptations based on the assumed linearized Gaussian approach. The simulated stand-alone and joint geophysical data sets are then inverted for lithofluid facies models under different prior inputs. Two challenging geoelectric scenarios also are tested, one with lower resistivity contrasts and another with a misguided background model. All results demonstrate a gain in precision and accuracy when associating these geophysical signals to estimate the oil column. Facies-conditioned inversions for the rock properties also indicate potential for quantitative reservoir interpretations.

Published: January 2024

Background

Functional somatic disorder (FSD) is a unifying diagnosis that includes functional somatic syndromes such as irritable bowel, chronic widespread pain (CWP) and chronic fatigue. Several psychological factors are associated with FSD. However, longitudinal population-based studies elucidating the causal relationship are scarce.

Aims

To explore if neuroticism, perceived stress, adverse life events (ALEs) and self-efficacy can predict the development of FSD over a 5-year period.

Method

A total of 4288 individuals who participated in the DanFunD baseline and 5-year follow-up investigations were included. FSD was established at both baseline and follow-up, with symptom questionnaires and diagnostic interviews. Neuroticism was measured with the short-form NEO Personality Inventory, perceived stress with the Cohen's Perceived Stress Scale, ALEs with the Danish version of the Cumulative Lifetime Adversity Measure and self-efficacy with the General Self-Efficacy Scale. Associations were investigated with multiple logistic regression models.

Results

Perceived stress predicted incident FSD, irritable bowel, CWP and chronic fatigue (odds ratios: 1.04–1.17). Neuroticism predicted incident FSD and chronic fatigue (odds ratios: 1.03–1.16). ALEs predicted incident FSD, CWP and chronic fatigue (odds ratios: 1.06–1.18). An increase in perceived stress from baseline to follow-up was associated with incident FSD, irritable bowel, CWP and chronic fatigue (odds ratios: 1.05–1.22). Contrary, an increase in self-efficacy seemed to be a protective factor (odds ratios: 0.89–0.99).

Conclusions

High neuroticism, high perceived stress and a high number of ALEs are risk factors for the development of FSD. Particularly perceived stress seems to be an important contributor to the onset of FSD.
Η συγχωρητικότητα στις διαπροσωπικές σχέσεις ως παράγοντας της ποιότητας ζωής
Authors: Κορέτση Ελένη
Published: January 2024

Η συγχώρηση ως στάση και συμπεριφορά χαρακτηρίζει τις διαπροσωπικές σχέσεις των ενηλίκων και αποτελεί μάλιστα το θεμέλιο για τη συνοχή και τη διαιώνιση αυτών. Η απονομή της συγχώρησης εξαρτάται από την προσωπικότητα του ατόμου, καθώς και από πολλούς απρόβλεπτους παράγοντες. Ένεκα της πολυπλοκότητας και της πολλαπλής σύνθεσης της συγχωρητικότητας, προσεγγίσαμε το θέμα της συγχώρησης από δύο επιστημονικές περιοχές της Αναπτυξιακής Ψυχολογίας και της Θεολογίας. Μας απασχόλησε κυρίως η γνήσια και αληθινή μορφή της συγχώρησης, που βασίζεται στην εκκλησιαστική παράδοση της Ορθόδοξης Εκκλησίας και που είναι καρπός της ασκητικής της αγάπης. Η Ορθόδοξη Εκκλησία, μέσα από τα Βιβλικά, Πατερικά και τα Λειτουργικά κείμενά της μας δίδαξε τη θεραπευτική αξία της συγχώρησης ως πρακτικά εφαρμόσιμης αρετής στο κοινωνικό περιβάλλον του σύγχρονου ανθρώπου. Σημαντικό εύρημα, που ανέδειξε η παρούσα έρευνα, σε δείγμα 150 ατόμων, είναι ότι οι ενήλικες με συγχωρητική διάθεση έχουν καλύτερη ψυχική ευεξία, καθώς το 46,4% δηλώνει ότι χαίρεται κατά πολύ όταν συγχωρεί, γιατί αποκαθιστά έτσι τη σχέση με το συνάνθρωπο και νιώθει ανακούφιση, γιατί εκτονώνεται η αρνητική ατμόσφαιρα στις διαπροσωπικές του σχέσεις, γεγονός που βοηθά την καλή ψυχική υγεία και αναβαθμίζει την ποιότητα της ζωής του. Ο ενήλικας συνδέει την έννοια της συγχώρησης με το πρότυπο της συγχώρησης του Χριστού, καθώς το 41,3% δηλώνει πως έχει ως πρότυπό του το Χριστό στη συγχώρηση και το 24,1% θεωρούν ότι οι θρησκευτικές τους πεποιθήσεις τους δίνουν πολλή δύναμη για να αντιμετωπίσουν τις δυσκολίες της ζωής. Η συγχώρηση φαίνεται να παρουσιάζει θετική συσχέτιση με τη μεταβλητή της ηλικίας, ενώ οι ωφέλειες της συγχωρητικότητας αναδεικνύονται στην θετική επίδραση αυτής στην ψυχοσωματική υγεία τού ανθρώπου.
Το σταντ-απ κόμεντι στην Ελλάδα
Authors: Ηλιάδης Αντώνιος
Published: January 2024

Το σταντ-απ κόμεντι είναι ένα πολύ διαδεδομένο είδος ζωντανού θεάματος στον δυτικό κόσμο. Εμφανίστηκε στις Ηνωμένες Πολιτείες και το Ηνωμένο Βασίλειο γύρω στα μέσα του 20ού αιώνα, οι ρίζες του, ωστόσο, μπορούν να εντοπιστούν στις ζωντανές μουσικές παραστάσεις με στοιχεία κωμικής πρόζας που δίνονταν στις χώρες αυτές από τα μέσα του 19ου αιώνα. Το κύριο χαρακτηριστικό τού είδους είναι το σπάσιμο του λεγόμενου «τέταρτου τοίχου» και η άμεση επαφή μεταξύ του προσώπου (ή των προσώπων) επί σκηνής και του κοινού: ο κωμικός απευθύνεται στο κοινό και συχνά αλληλεπιδρά με αυτό. Στην Ελλάδα, το σταντ-απ κόμεντι εισήχθη στα μέσα της δεκαετίας του 1970, αν και δεν αναφερόταν με αυτό το όνομα παρά μόνο μετά από σχεδόν δύο δεκαετίες. Καθοριστικός παράγοντας για την εισαγωγή του ήταν η επιστροφή του κωμικού Βασίλη Τριανταφυλλίδη (καλλιτεχνικό ψευδώνυμο: Χάρρυ Κλυνν) τον χειμώνα τού 1974, αφού είχε ζήσει και εργαστεί για δέκα και πλέον χρόνια στις σταντ-απ σκηνές τής Βόρειας Αμερικής (Μόντρεαλ, Σικάγο, Νέα Υόρκη), είτε ως περφόρμερ είτε ως συγγραφέας κωμικών κειμένων για άλλους κωμικούς. Τα επόμενα χρόνια, αυτό το είδος ζωντανής -κυρίως μονοπρόσωπης- κωμωδίας παρέμεινε στο περιθώριο, ως εναλλακτικό και μάλλον υπόγειο είδος θεάματος. Στα μέσα τής δεκαετίας τού 1990, η σκηνοθέτις Λουκία Ρικάκη δημιούργησε μια ομάδα ημιεπαγγελματιών κωμικών που έδιναν τακτικές παραστάσεις στην Αθήνα· τότε το σταντ-απ κόμεντι αποκλήθηκε για πρώτη φορά στην Ελλάδα με το όνομά του. Η βιντεοσκόπηση των παραστάσεων και η προβολή τους σε τηλεοπτικό κανάλι πανελλαδικής εμβέλειας έδωσε σημαντική ώθηση στο είδος και το κατέστησε αναγνωρίσιμο στο ευρύ κοινό. Μια επιπλέον ώθηση δόθηκε στις αρχές τής δεκαετίας τού 2010, με την επιστροφή δύο Ελλήνων κωμικών που είχαν εργαστεί με επιτυχία στο εξωτερικό, του Λάμπρου Φισφή και της Κατερίνας Βρανά. Κατά το πρώτο μισό της δεκαετίας, πραγματοποιήθηκαν στην Αθήνα και τη Θεσσαλονίκη οι πρώτες τακτικές παραστάσεις ανοιχτού μικροφώνου (open mic). Παράλληλα, αρκετοί χώροι σε όλη την Αθήνα και τη Θεσσαλονίκη λειτουργούσαν ως κόμεντι κλαμπ και διοργανώνονταν σε ετήσια βάση φεστιβάλ κωμωδίας. Έκτοτε, το σταντ-απ κόμεντι γνωρίζει μια σταθερή και ραγδαία άνθηση ως είδος.
The role of heavy and light chain V regions in antigen binding by Fv domains of antibodies to Z-DNA
Authors: Πολυμένης Μιχαήλ
Published: January 2024

Τα αντισώματα στο Z-DNA μπορούν να προκληθούν με ανοσοποίηση και βρίσκονται επίσης σε αυτοάνοσα άτομα. Έτσι, τα αντισώματα αντι-Ζ-DNA αντιπροσωπεύουν μια αυτοάνοση ειδικότητα που μπορεί να αναπαραχθεί πειραματικά. Το μεταβλητό θραύσμα (Fv) του αντισώματος αντι-Ζ-DNA Ζ22 εκφράστηκε από Ε. coli ως Fv μονής αλυσίδας (ScFv). Όταν η μεταβλητή περιοχή ελαφριάς αλυσίδας (VL) του Z22 αντικαταστάθηκε με μια βιβλιοθήκη διαφορετικών VL cDNA, μόνο ένα VL από πολλές εκατοντάδες, το οποίο διέφερε μόνο σε πέντε υπολείμματα από αυτό του Z22, υποστήριξε τη δέσμευση Z-DNA. Αυτό το VL έδωσε ένα scFv (LZ1-2) με ειδική δέσμευση Z-DNA, αλλά η συγγένειά του ήταν 100 έως 200 φορές χαμηλότερη από εκείνη του Z22. Η αντικατάσταση της κωδικοποιούμενης από VH10 αλυσίδας Z22 VH με έντεκα άλλα VH που κωδικοποιούνται από VH10 μείωσε τη δραστηριότητα σύνδεσης του Z-DNA, αλλά αύξησε τη δέσμευση στο Β-DNA και το μετουσιωμένο DNA. Αυτά τα VH είχαν ποικίλη περιοχή προσδιορισμού της συμπληρωματικότητας 3 (CDR3). Ένα scFv (Z3-3) που δεν δέσμευε το Z-DNA διέφερε από το Z22 σε δέκα μόνο θέσεις VH, τέσσερις από τις οποίες ήταν σε CDR3. Η εναλλαγή τμημάτων γονιδίου και η τοποκατευθυνόμενη μεταλλαξογένεση έδειξαν ότι η κύρια συνεισφορά του Z22 VH είναι το CDR3 του. Ένα scFv με την περιοχή πλαισίου CDR3 4 (CDR3-FR4) του Z22 και το τμήμα VH του Z3-3 είχε την ίδια επιλεκτική δέσμευση Z-DNA υψηλής συγγένειας με το Ζ22. Τοποκατευθυνόμενη μεταλλαξογένεση έδειξε ότι τα N99 και S98 στο Z22 VH, και F96 στο VL, ήταν σημαντικά για τη δέσμευση αντιγόνου. Ορισμένες υποκαταστάσεις στο VH CDR3 μετέτρεψαν το εκλεκτικό Z22 scFv σε ένα πολυδραστικό scFv με δέσμευση παρόμοια με αυτοαντισώματα με Β-DNA και μετουσιωμένο DNA. Οι χωριστά εκφραζόμενες περιοχές Z22 V συσχετίζονται στοιχειομετρικά για την ανασύσταση της θέσης αντιγόνου-μπινδίνης. Μια μετάλλαξη VL F96W, η οποία στο LZ1-2 scFv μείωσε τη συγγένεια δέσμευσης αντιγόνου κατά δύο τάξεις μεγέθους, δεν μείωσε τη συγγένεια της αλληλεπίδρασης VH-VL, που μετρήθηκε με συντονισμό επιφανειακού πλασμονίου. Η απομονωμένη περιοχή Z22 VL δεν αλληλεπιδρά με νουκλεϊκά οξέα, αλλά η περιοχή VH μόνη της δέσμευε το Z-DNA ειδικά με μια συγγένεια παρόμοια με αυτή των Fab ή Fvs του Ζ22 (KD=1,68x10^-8 Μ). Η δέσμευση Z22 VH στο αντιγόνο αναστέλλεται μέσω συσχέτισης με το LZ1-2 VL, (με την αντικατάσταση F96W). Αυτά τα αποτελέσματα in vitro μοιάζουν με την in vivo ρύθμιση της αυτοαντιδραστικότητας της αλυσίδας Η που συμβαίνει με την υποκατάσταση της αλυσίδας L στην επεξεργασία υποδοχέα.

Approximation of piecewise linear and generalized functions
Authors: Alyukov Sergey
Published: January 2024

The monograph is devoted to piecewise linear and generalized functions. They are widely used in various fields of research: in the theory of signal transmission and transformation, quantum field theory, control theory, problems of nonlinear dynamics, structural mechanics, semiconductor theory, economic applications, medicine, description of impulse effects and many others. When creating mathematical models, in some cases it is necessary to approximate these functions using analytical expressions, but not in the form of linear combinations, as in known methods, but in the form of attachments, compositions, using recursive sequences.
The considered methods are devoid of the disadvantages of Fourier series and have advantages over other approximation methods. The developed approximation methods help to understand the meaning and content of generalized functions and their derivatives, and contribute to the conscious application of these functions in mathematical modeling problems. These methods can be used in a wide range of applied research, from medicine to quantum electronics. The theoretical material is illustrated by a large number of practical examples from a wide variety of applied fields. The fundamentals of the developed macroeconomic theory with impulse, shock, spasmodic characteristics and other types of rapidly changing processes are presented.
For mathematicians, students and teachers, and specialists working in applied research fields.

Temporal development of the displacement field of the Ponzano landslide in February 2017
Authors: Łucka Magdalena , Hejmanowski Ryszard , Witkowski Wojciech
Published: January 2024

The conducted research determined the temporal evolution of the displacement field for the Ponzano landslide case study. The offset-tracking method, so far used mainly for the relatively rapid but uniform displacement of glaciers, was tested for the 2017 study of the Ponzano landslide in Italy. The suitability of the method for high-resolution TerraSAR-X and medium-resolution Sentinel-1 imagery was investigated. The results proved the applicability of the OT method for studying processes with high and variable displacement dynamics. However, for such purposes, high-resolution radar data are crucial. With an uncertainty in the determination of residual displacements of about ±1 m, it was shown that the values of residual displacements occurring up to several days after the main phase of landslide movements are within the range of uncertainty but are determinable. The research conducted in the paper filled a gap in the analysis of the phenomenon just after the main movement phase. It allowed determination of the time and speed of extinction of landslide movements.

La regeneración urbana constituye un proceso que no solo transforma el entorno físico, sino que representa un enfoque de intervención en el que los principios de inclusión social, resiliencia, compacidad, participación comunitaria y prosperidad socioeconómica son el punto de partida para el desarrollo sostenible. De manera concreta, los espacios perimetrales del río Guadalmedina en Málaga se ven actualmente muy afectados por el turismo. Este contexto particular permite acercamos a un escenario que supone un ejemplo ilustrativo de la realidad compleja que vivimos en las ciudades históricas, en las que su patrimonio se ha revertido en reclamo de un turismo que refuerza los vínculos, pero, al mismo tiempo, los pervierte hasta el punto de dejar de ser una ciudad turística para conformar una ciudad turistizada.
Integrating reality counseling with the creative arts as a counselor's professional practice: A review literature
Authors: Titing Herman
Published: January 2024

Counselor creativity is one aspect that needs to be strengthened by counselors in providing counseling services. The creativity of this counselor can encourage the emergence of meaningful counseling services and significantly impact changes in counselee behavior. This article explains the integration of reality counseling with the creative arts. This article is a structured and systematic literature review of the development of ideas and reality counseling research related to the creative arts. This article is an analysis of 51 articles published from 2010 to 2020. In addition, three scientific articles directly relate to combining creative arts and reality counseling. A study of these articles found that creative arts can increase the effectiveness of reality counseling with the WDEP (wants, doing, evaluation, planning) system pattern. Creative arts supporting the efficacy of the WDEP system pattern of reality counseling are drawings, puppets, metaphors, and sand trays. The combination of reality counseling by utilizing creative arts such as drawing, puppets, metaphors, and sand trays produces operational guidelines for counselors consisting of four counseling sessions.   Integrating creative arts into reality counseling is a form of professionalism for counselors in counseling services. Operating procedures for combining reality counseling with creative arts are discussed in this article. The findings of this study provide recommendations for further research to identify the effectiveness of counseling empirically in overcoming specific problems in counselees.
Spirituality-based narrative counseling model to reduce self-injurious behavior in Islamic boarding school students
Authors: Sari Dita Kurnia , Abidin Muhammad Nasrullah bin Zainal
Published: January 2024

The aim of this research is to develop a spirituality-based narrative counseling model to reduce self-injurious behavior. The basis for developing this counseling model is a postmodern approach by adapting the spiritual values inherent in Islamic boarding school students. The development of a spirituality-based narrative counseling model in this research is based on the research and development model of Borg & Gall (1983) and only focuses on three main stages, including: (1) identifying students' self-injurious behavior profiles; (2) draft a hypothetical spirituality-based narrative counseling model to reduce students' self-injurious behavior; and (3) conducting an acceptability test of the model developed through one expert in the field of guidance and counseling and one Islamic boarding school counselor. The data analysis technique used in this research is quantitative and descriptive analysis. The results of the study showed that the level of self-harming behavior of Islamic boarding school students in Taman District, Sidoarjo Regency was 14.80% indicating a high level of self-injuring behavior, 59.54% a moderate level of self-injuring behavior and 30.61% a low level of self-injuring behavior. Based on the results of the analysis, a spirituality-based narrative counseling model which includes six stages is acceptable (feasible) for use by counselors in Islamic boarding schools. The results of this research can be followed up by future researchers by testing the effectiveness of spirituality-based narrative counseling to reduce self-injurious behavior in Islamic boarding school students

Abstract. Fatonah S, Hamidy R, Mulyadi A, Efriyeldi. 2023. Biomass, carbon stock and sequestration in various conditions of mangrove forests in Sungai Apit, Siak, Riau, Indonesia. Biodiversitas 24: 5837-5846. The value of aboveground carbon is influenced by differences in conditions of the mangrove. Therefore, this study aimed to estimate biomass, as well as carbon stock and sequestration in various mangrove forests within Sungai Apit Siak, including natural, rehabilitated, and degraded forests. The Line Transect Plot method was used for sampling. Aboveground biomass was determined using an allometric equation based on mangrove stem diameter. Stem diameter measurements were taken from mangrove vegetation in three forest conditions across three villages in Sungai Apit, Siak. The findings revealed that natural forests contained higher values of biomass, carbon stock, and sequestration at 256, 128, and 470 tons/ha, respectively, compared to rehabilitated and degraded forests. The variability in these parameters across different mangrove forests was influenced by stands characteristics, specifically basal area and mean tree diameter, which were associated with the age of mangrove vegetation and recovery duration. Notably, Rhizophora mucronata, Sonneratia caseolaris, and Avicennia alba exhibited the highest carbon sequestration. These results highlighted that Sungai Apit mangrove forests store a relatively high carbon stock, emphasizing the importance of implementing proper conservation and management measures to ensure sustainability.

Abstract. Safitri D, Wiyono S, Purbajanti ED. 2023. Potential of endophytic yeasts as biocontrol of Phytophthora capsici, causative agent of foot rot disease on black pepper. Biodiversitas 24: 5847-5853. Phytophthora capsici is the main pathogen of foot rot disease of black pepper. This disease contributes to a significant decrease in black pepper productivity. Conventional disease management strategies usually require the use of chemical pesticides, which can have harmful environmental and human health consequences. Introducing biological agents such as endophytic yeasts for controlling foot rot disease has minimal effect on human health and is sustainable. One technique to control foot rot disease is to use biological agents such as endophytic yeasts. The aim of this research was to find yeast against Phytophthora capsici. The methods used included (i) study development and identification of endophytic yeast and (ii) in vitro and in vivo antagonism screening of yeast against P. capsici. The results showed that 49 endophytic yeasts were isolated from the leaves, fruits and roots of three black pepper lines. Five isolates had selected based on the highest antibiosis in antagonism test by in vitro: END6, END21, END66, END87, and END14. Isolate END87 had a mycelium inhibition rate of 64.55%, and a low level of inhibition was found in isolate 21, which had a mycelium size of 42.81%. The molecular characterization based on the sequence partial of NL1 and NL4. Moreover, 5 isolates of endophytic yeast (END6, END21, END66, END87, and END14) were identified as Rhodotorula mucilaginosa, Hannaella oryzae, Cryptococcus tephrensis.

Abstract. Lelono TD, Bintoro G, Harlyan LI, Setyanto A, Rihmi MK, Rudianto D. 2023. Biological aspect approach in sustainable management of coral catshark Atelomycterus marmoratus (Anonymous [Bennett], 1830) in Bali Strait, Indonesia. Biodiversitas 24: 5873-5882. Coral catshark (Atelomycterus marmoratus) is a shark species that thrives in many coral reefs. to evaluate the biological aspects of A. marmoratus and their type of growth curve for a time series to support their sustainability. Sampling was performed from August 23rd, 2019, to March 31st, 2020. The morphological analysis was performed by recording or photographing to reduce possible errors. Then, the length-weight relationship, sex ratio, length at first captured and matured, and spawning ratio were evaluated. The present study demonstrated that the coral catshark captured in the cohort that produces two cohorts only happens in February. The sex ratio is 41.6% male and 48.4% female, which is considered healthy, whereas the remaining percentage is so severely damaged that its gender cannot be determined. The FISAT-II software analysis results in a von Bertalanffy growth formula of Lt = 76.21 (1-e-2.01(t+0.0596)) with t max = 1.49/ year and L max = 77.39 cm. They grow steadily or tend to slow down after they reach the age of 1.5 years, with an asymptotic length of 77.39 cm. The Lc value (67.5 cm) is more significant than their Lm value (53 cm), indicating that their sustainability is highly possible to maintain because only fish that have passed the spawning stage are captivated. The spawning potential rate (SPR) is 35%, with M = 0.66, E = 1.85, and F = 0.78. These results indicate that the exploitation rate of coral catshark is moderate because 20% < SPR < 40%.  In conclusion, the A. marmoratus length-weight relationship is categorized as negative allometric, where the length grows faster than the weight.

Abstract. Siahaan GF, Chozin MA, Syukur M, Ritonga AW. 2023. Estimation of genetic parameters and variability of various cayenne peppers under net shading. Biodiversitas 24: 5912-5919. The intercropping systems are important concerning the decreasing agricultural land and the increasing population. Chili could be planted as intercrops, but not all chili genotypes were adapted to low light-intensity stress. This study aims to determine the genetic diversity of cayenne pepper under 50% plastic net shade conditions based on morphological and agronomic traits. The study was conducted at the Cikabayan Experimental Field, Institut Pertanian Bogor, Dramaga, Bogor, from January to July 2021. The genetic material consisted of ten genotypes of cayenne pepper from Capsicum annuum L. and ten from Capsicum frustescens L.. Each genotype of chili was planted with three replications, so there were 60 experimental units. Each experimental unit consisted of six plants planted in an area of 1.5 m2. The shade used was a plastic net shade with a 50% shading level. The estimation of genetic parameters showed that leaf area, number of leaves, fruit weight, number of fruits, and yield per plant had a high genotypic coefficient of variation (GCV) and broad-sense heritability (Hbs). Cluster analysis resulted in two main clusters based on twelve chili growth and agronomic characters. All chili genotypes included in Cluster 1 were C. annuum chilies. On the other hand, all the chili genotypes in Cluster 2 were C. frutescens chilies except for the G19 genotype. Cayenne pepper in Cluster 2 had a higher number of leaves, plant height, stem diameter, leaf area, fruit diameter, pedicle length, fruit weight, number of fruits, and yield per plant than cayenne pepper in Cluster 1. The result of this study indicates that C. frutescens cayenne pepper has more potential to be planted under shading conditions and used in intercropping than C. annuum.

Abstract. Witasari LD, Lizar DP, Florencia OM, Ramadhan A, Fiana NAO, Supriyadi S, Pratiwi SUT, Nandika D, Karlinasari L, Arinana A, Batubara I, Santoso D, Rachmayanti Y, Firmansyah D, Sudiana IK, Hertanto DM, Rachmayanti Y, Firmansyah D. 2023. Designing antimicrobial active packaging films based on chitosan plus fungus comb ethyl acetate extract from Indo-Malayan termite mounds. Biodiversitas 24: 5947-5955. Antimicrobial active packaging systems incorporate antimicrobial compounds into polymer films, i.e., chitosan, thus suppress spoilage microorganism growth in foods. Chitosan films itself cannot prevent microbial growth, thus other antimicrobial agent must be added. Fungus comb extract from Indo-Malayan termite (Macrotermes gilvus (Hagen, 1858)) mounds is a potential active organic antimicrobial compound, which can be incorporated into chitosan films. The purpose of this study was to develop and characterize active packaging films based on chitosan plus an antimicrobial fungus comb ethyl acetate extract. Films contained 1% chitosan and fungus comb ethyl acetate extract (0.5, 1, 2, and 5% w/v). Notably, films containing 2 and 5% extracts inhibited Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), and Pseudomonas aeruginosa (ATCC 27853), but not fungi. Films plus 2% extract showed a thickness, tensile strength, and strain of 0.13 mm, 2.15 MPa, and 32.55%, respectively. Films had a moisture content of 0.26%, water solubility of 2.68%, swelling property of 2.37%, and water vapor permeability (WPV) of 3.31×10?10 g.m?1s?1.Pa?1. They displayed smooth morphology but no new functional groups. Thus, chitosan plus 2% of fungus comb ethyl acetate extract can be used in antimicrobial active packaging films for food application. It could be applied as a green alternative to prolong the shelf-life of food products.

Abstract. Hidayati S, Agustin AT, Sari EK, Sari SM, Destiawan RA, Silvana WA. 2023. Phytochemical profiling and antidiabetic evaluation of Peperomia pellucida as a potential alpha glucosidase inhibitor. Biodiversitas 24: 5972-5978. One strategy in post-prandial hyperglycemic control can be done by inhibiting the digestion of dietary carbohydrates through the inhibition of alpha glucosidase enzymes. This study was conducted to determine the antidiabetic activity of Peperomia pellucida in inhibiting the alpha glucosidase. An inhibitory activity analysis test was carried out on alpha glucosidase in vitro and in silico using alpha glucosidase. Molecular docking between receptors and ligands was performed using Hex 8.0 software. The setting column is set in Shape+Electro+DARS mode. The results showed ethanol extract and ethyl acetate fraction in vitro showed the ability to inhibit the activity of alpha glucosidase enzyme with C50 values of 13.43 mg/mL and 9.73 mg/mL respectively with IC50 positive control acarbose values of 8.11 mg/mL. The results of in silico analysis showed that the Patuloside A component was able to bind to the binding site of alpha glucosidase and gave the smallest binding energy value with a value of -321.4 kcal/mol compared to isovitexin, isoswertisin, pellucidatin, and caryatin-7-O-?-rhamnoside compounds. P. pellucida has the potential to be developed as an antidiabetic agent that has activity in inhibiting the work of the enzyme alpha glucosidase so that it can reduce blood glucose levels.

Abstract. Ruziyev F, Djabbarov I, Olimjonova S, Niyozov U, Urokov S, Ishankulova D, Bakhadirov U. 2023. Grain quality indicators and their phenotypic variability of ancient varieties of Triticum aestivum in the mountains of Uzbekistan. Biodiversitas 24: 5995-6001. Today, creation of varieties of agricultural crops that are resistant to adverse environmental factors and produce stable crops under the influence of stress factors has become one of the most important issues in the world. In the following years, scientific and research work is being carried out on the wide use of the diversity of its genetic resources in the creation of new varieties of wheat (Triticum aestivum L.). In this regard, there are opportunities to use wild, semi-wild and ancient local forms of wheat with high protein and high gluten content to create varieties that meet modern production requirements. Therefore, it is important to evaluate the quality indicators of ancient varieties and the degree of phenotypic variation in the selection of wheat varieties that are resistant to adverse environmental factors, fertile and high-quality. This research work, aimed at researching ancient wheat varieties cultivated by the people living in the mountainous regions of Uzbekistan for many years. According to the research results, the grain quality indicators (grain hardness, diameter of grains, grain quality indicators, rheological properties, etc.) of the ancient wheat varieties distributed in the mountain regions are different. According to the results of the experiment, the grain hardness of the studied ancient wheat varieties is 73-82 µm, grain diameter 2.65-2.71 mm, hectolitre of weight 818.2-838.1±8.7 g/L, vitreousness 62.2-70.3%, gluten content in grain 31.5-34.6%, sedimentation index 64.4-77.2 mL. It was also observed that the phenotypic variability of the quality indicators was different in the wheat varieties that were the object of the study. Differences in the grain quality indicators of ancient wheat varieties are explained by the different effects of climatic parameters, abiotic and biotic factors in the regions where wheat grows. The information presented in the article provides an opportunity to select ancient wheat varieties distributed in the mountainous regions of Uzbekistan as starting sources for the creation of varieties with high nutritional value, resistant to adverse factors.
