Polygonal Serpentine and Chrysotile in the Kurosegawa Belt, Kyushu, Japan
Authors: Enju Satomi , Uehara Seiichiro , Inoo Teruo 
Published: March 2023

AbstractThe basic crystallographic properties of polygonal serpentine (PS) have been revealed in previous studies, while their variation, occurrence, and formation conditions are poorly understood. This study defines four categories of chrysotile and PS: clinochrysotile (chrysotile 2Mc1), orthochrysotile (chrysotile 2Orc1), clino-type PS, and ortho-type PS. When chrysotile and PS coexist or are indistinguishable, we will call them fibrous serpentine (FS), regardless of their ratios. By researching the occurrence, distribution, microtexture, crystal structure, and chemical composition of PS and chrysotile based on these categories, we reveal the features of each type and discuss their relationships and formation processes. The chrysotile and PS of the Kurosegawa belt in Kyushu are enriched in ortho-type FS (O-FS) compared with other localities. O-FS-enriched samples (group-O) show a linear, wide vein occurrence and splintery texture or irregular veins with space-filling textures, while clino-type FS (C-FS)-enriched samples occur as thin veins in serpentinites or as massive-foliated aggregates. Polygonal serpentine is more frequently seen in group-O compared with group-C. In our observation, the crystal structure of chrysotile and PS is continuous, making it difficult to define a clear border between them. Ortho-type PS is frequently seen, whereas clino-type PS is absent in most localities. Orthochrysotile tends to grow into 15-sectored ortho-type PS, whereas clinochrysotile grows into 30-sectored clino-type PS. These features of the crystal structure and coexistence and proportion of the fibrous serpentines in each group were mostly common in all studied localities in the Kurosegawa belt in Kyushu, indicating similar formation conditions within group-O or -C. Based on the textures and occurrences, group-O formed by crystallization from the fluid in the fracture made by brittle deformation, while group-C formed in the last stage of alteration mainly by replacement by alteration. The serpentines in the Kurosegawa belt in Kyushu seem to have followed a similar process, at least at the late stage of serpentinization where FS forms and the difference in the ratio of C-FS to O-FS may have been derived from the difference in the timing of formation during the emplacement process. A formation model for chrysotile and PS is proposed based on these observations. In this model, C-FS and O-FS form under different conditions, such as differences in pressure. This model still needs verification by further observations at different localities and by synthetic experiments.

Tidal Heating of Exomoons in Resonance and Implications for Detection
Authors: Tokadjian Armen , Piro Anthony L. 
Published: March 2023

Abstract
The habitability of exoplanets can be strongly influenced by the presence of an exomoon, and in some cases the exomoon itself could be a possible place for life to develop. For moons outside of the habitable zone, significant tidal heating may raise their surface temperatures enough for them to be considered habitable. Tidal heating of a moon depends on numerous factors such as eccentricity, semimajor axis, size of parent planet, and the presence of additional moons. In this work, we explore the degree of tidal heating possible for multimoon systems in resonance using a combination of semianalytic and numerical models. This demonstrates that even for a moon with zero initial eccentricity, when it moves into resonance with an outer moon, it can generate significant eccentricity and associated tidal heating. Depending on the mass ratio of the two moons, this resonance can either be short-lived (≤200 Myr) or continue to be driven by the tidal migration of the moons. This tidal heating can also assist in making the exomoons easier to discover, and we explore two scenarios: secondary eclipses and outgassing of volcanic species. We then consider hypothetical moons orbiting known planetary systems to identify which will be best suited for finding exomoons with these methods. We conclude with a discussion of current and future instrumentation and missions.
Protracted Timescales for Nebular Processing of First-formed Solids in the Solar System

Published: March 2023

Abstract
The calcium–aluminum-rich inclusions (CAIs) from chondritic meteorites are the first solids formed in the solar system. Rim formation around CAIs marks a time period in early solar system history when CAIs existed as free-floating objects and had not yet been incorporated into their chondritic parent bodies. The chronological data on these rims are limited. As seen in the limited number of analyzed inclusions, the rims formed nearly contemporaneously (i.e., <300,000 yr after CAI formation) with the host CAIs. Here we present the relative ages of rims around two type B CAIs from NWA 8323 CV3 (oxidized) carbonaceous chondrite using the 26Al–26Mg chronometer. Our data indicate that these rims formed ∼2–3 Ma after their host CAIs, most likely as a result of thermal processing in the solar nebula at that time. Our results imply that these CAIs remained as free-floating objects in the solar nebula for this duration. The formation of these rims coincides with the time interval during which the majority of chondrules formed, suggesting that some rims may have formed in transient heating events similar to those that produced most chondrules in the solar nebula. The results reported here additionally bolster recent evidence suggesting that chondritic materials accreted to form chondrite parent bodies later than the early-formed planetary embryos, and after the primary heat source, most likely 26Al, had mostly decayed away.

Published: March 2023

We compiled a database of firefly species records from the Atlantic Forest hotspot in Brazil and made it available at GBIF. Data were gathered from literature and from several key entomological collections, including: Coleção entomológica Prof. José Alfredo Pinheiro Dutra (DZRJ/UFRJ) and Coleção do Laboratório de Ecologia de Insetos from Universidade Federal do Rio de Janeiro (CLEI/UFRJ); Coleção Entomológica do Instituto Oswaldo Cruz (CEIOC); Museu de Zoologia da Universidade de São Paulo (MZSP); Coleção Entomológica Pe. Jesus Santiago Moure from Universidade Federal do Paraná (DZUP/UFPR); and Coleção Entomológica from Universidade Federal Rural de Pernambuco (UFRPE). This database represents the largest contribution to a public repository of recorded occurrences from Neotropical fireflies.
This dataset shows the occurrence and abundance of firefly species in the Atlantic Forest hotspot. Firefly species endemic to this biome are also present and considered in the study. These data can assist scientific and societal needs, by supporting future research projects and conservation decision-making.
Les établissements perchés de l’Antiquité tardive et du haut Moyen Âge en Franche-Comté (IVe-IXe siècle) : la reculée de Baume-les-Messieurs et le val de Voiteur (Jura)
Authors: Billoin David , Gandel Philippe 
Published: March 2023

Ce bref panorama des acquis de la recherche sur les établissements perchés et fortifiés tardo-antiques et alto-médiévaux en Franche-Comté s’illustre par une étude de cas d’un espace géographique particulièrement dynamique : la reculée de Baume-les-Messieurs et le val de Voiteur. Situé au nord de Lons-le-Saunier sur le piémont du Jura, longé par une grande voie et traversé par des axes qui mettent en relation les plateaux du Jura et la plaine de Bresse, ce secteur est densément occupé depuis la Protohistoire. Il se caractérise par une densité des occupations de hauteur fortifiées en lien probablement avec le contrôle et la gestion du sel. Une économie réactivée après la « parenthèse » romaine qui voit la réoccupation de bon nombre de ces points hauts stratégiques jusqu’à l’aube de la période féodale.

Published: March 2023

ABSTRACT

Aim:
The quality of obturation with recent capillary condensation technique and hybrid technique in teeth with artificial internal resorption cavity needs to be evaluated.

Methods:
Calculation of sample size was done with G*Power software (version 3.1.9.4) (effect size d = 1.46). Eighteen single-canal mandibular premolars were decoronated at the cementoenamel junction for standardization of specimen length as 12 mm. Biomechanical preparation was done with ProTaper Universal rotary file up to F4. Internal resorption cavity was prepared with #08 size round bur 6 mm from the apex. Samples were distributed randomly into two groups. Group I: teeth with bioceramic sealer (EndoSequence BC Sealer, Brasseler, USA) application using conventional technique and hybrid technique of obturation. Group II: capillary condensation technique of bioceramic sealer (EndoSequence BC Sealer, Brasseler USA) using single-cone gutta-percha obturation. The voids in three segments of the root canal were measured with cone-beam computed tomography using “OnDemand3D App” software. Data were statistically analyzed by one-way analysis of variance (ANOVA) and multiple comparisons of Tukey honestly significant difference tests with P < 0.05.

Results:
The mean area of the void was 0.3963 ± 0.3299 mm2 for Group I and 0.4022 ± 0.4101 mm2 for Group II. There was a difference in the number of voids present in different sections of the root within a group with significance but not between the groups.

Conclusion:
Capillary condensation technique with single-cone obturation is comparable to conventional sealer application and hybrid technique of obturation for filling internal resorption cavity.

Published: March 2023

ABSTRACT

Aims:
The aim of the present study was to evaluate and compare the push-out bond strength of single and multiple fiber-reinforced posts cemented with dual-cure resin cement using total-etch and self-etch adhesive systems.

Methods:
Sixty single-rooted maxillary permanent incisors were decoronated and endodontically treated. Following post space preparations, the roots were divided into four groups (n = 15); Group 1: single fiber-reinforced composite post with the total-etching agent, Group 2: single fiber-reinforced composite post with the self-etching agent, Group 3: multiple pin posts with the total-etching agent, and Group 4: multiple pin posts with the self-etching agent and then cemented using dual-cure resin cement. The samples were then sectioned to obtain approximately 2-mm disks, and a push-out test was performed. Data obtained were statistically analyzed using analysis of variance, post hoc Tukey, and unpaired t-test.

Results:
The mean push-out bond strength values showed that Group 3 had significantly higher bond strength as compared to the other groups (P < 0.05).

Conclusions:
Dentapreg multiple pin posts with total-etching agents resulted in higher push-out bond strength as compared to single fiber-reinforced posts and self-etching agents.
Foramen Magnum as a Tool for Sexual Dimorphism
Authors: Kattimani Ashokkumar , Swetha K , Bhayya Harsha , Kardalkar Shruti B. 
Published: March 2023

Background:
Gender determination by skeletal relies predominantly on the skeletal radiology. Foramen magnum is in a favorable anatomic position, protected by soft tissue and skeleton of the head protecting the area for forensic examination. Foramen magnum being a relatively indestructible structure becomes an important tool in identification of gender.

Objective:
To study the vagueness and reliability of the foramen magnum (FM) in gender classification through the use of reconstructed computed tomography (CT) images.

Materials and Method:
A total of 200 patients (100 males and 100 females; age range, 18–60 years) were selected for the study. The FM measurements (sagittal, transverse, circumference, and area) were obtained from reformatted axial sections using a CT scan.

Results:
It was found that the mean FM sagittal diameter was 35.09 ± 2.48 mm, the FM transverse diameter was 28.76 ± 2.82 mm, the FM circumference was 110.56 ± 8.84 mm, and the FM area was 746.20 ± 108.47 mm2. According to Student’s t-test results, in all measured parameters, there was a significant difference between the genders (P < 0.001).

Conclusion:
In all of the measured variables, there is a statistically significant difference present in the mean values of various parameters between both genders, with males having higher dimensions than female, indicative of sexual dimorphism.

Authors: Sailaja Sambhana , Shil Malabika , Lavanya Reddy , Thomas Delphia , Kondoj Navyasree , Komanduri Sowmya 
Published: March 2023

Background:
Mucormycosis is a potentially lethal fungal infection, and the risk of secondary infections is more in patients with COVID-19. This may be because of pre-existing comorbidities or the immunosuppressive treatment taken during the COVID-19 infection. Early diagnosis is of utmost importance for patient survival.

Aims and Objectives:
This study was designed to grade the patients of rhino-orbital-maxillary mucormycosis in post-COVID-19 patients in a structured way based on the symptoms and clinical and radiographic findings and to find a correlation with various predisposing factors.

Materials and Methods:
A total of 102 patients with confirmed rhino-orbital-maxillary mucormycosis and a history of COVID-19 recovery, who understand the protocol and can give informed consent, were included in the study.

Results:
In the present study, 73.5% were found to be males and 26.5% were found to be females. The 31–40 age group was more affected among males, and the 41–50 age group was among females. The most common associated comorbidity was found to be uncontrolled diabetes mellitus. Out of 102 patients, 53.9% patients reported being in grade II, followed by 33.3% in grade III, and 12.7% in grade I.

Conclusion:
The grading system of rhino-orbital-maxillary mucormycosis was found to be significant; hence, it can be used for the early diagnosis and prevention of severe consequences.

Authors: Jan Syeda Muskan , Pachipulusu Balaji , Govindraju Poornima 
Published: March 2023

Background:
Frontal sinus pattern is unique for each individual which has made it an important tool in forensic sciences. The dimensions of the maxillary sinus also tend to stabilize after puberty and remain intact when skull bones are poorly disfigured. These sinuses exhibit different dimensions among male and female subjects. Nasal septum patterns can be utilized as a tool.

Aims and Objective:
The present study is intended to determine the sexual dimorphism with dimensions of the frontal sinus, maxillary sinus, and nasal septum pattern by cone beam computed topography.

Materials and Method:
The study subject consisted of 100 images of CBCT images which were collected from the database retrospectively. The obtained data were statistically analyzed.

Results:
The parameters were higher in male in comparison to female subjects. The length, height of the maxillary sinus, and frontal sinus width showed statistically significant results. The deviated nasal septum was not statistically significant.

Conclusion:
The maxillary sinus and frontal sinus are utilized for personal identification and gender determination with the nasal septum as an adjuvant tool.
Cysteamine Hydrochloride, a Transglutaminase2 Inhibitor as Therapeutic Potential for Oral Submucous Fibrosis
Authors: Rajarathnam Basetty N. , Rakesh Nagaraju , Murali Anita , Anbu J , Asha M. L. 
Published: March 2023

Background:
Submucous fibrosis (SMF) was recognized as a definitive lesion by Schwartz who described it as a fibrosing condition in 1952 and due to its predilection for afflicting multiple sites in the oral cavity the disorder was listed as a “premalignant/precancerous condition”. Tissue transglutaminase 2 (TG2) catalyzes the cross-linkage between glutamine (Gln) and lysine (Lys) side chains. Cysteamine by virtue of being a transglutaminase 2 substrate, acts as a competitive inhibitor of the other amine substrates of this enzyme. In-vitro studies have reported the existence of a correlation between TG2 and SMF.

Aim:
The present study was carried out to evaluate Transglutaminase2 (TG2) and its therapeutic intervention by cysteamine hydrochloride in SMF-affected Wistar rats.

Methods:
The present experimental study was carried out on male Wistar rats, in which arecoline was injected into the right buccal mucosa for induction of SMF, and levels of TG2 were estimated using ELISA. The drug was administered to disease-induced Wistar rats from the 91st day for inhibition of TG2 and the post-treatment levels of TG2 were evaluated by ELISA at three regular intervals (97th, 104th, 111th days).

Results:
The Animal model exhibited a successful induction of SMF similar to the histopathological features of human SMF. The levels of TG2 were significantly elevated in the experimental animals compared with the healthy animal group up on the induction of the disease process. On administration of cysteamine to the SMF-affected animals, TG2 levels significant reduction by the 111st day was observed.

Conclusion:
The results from this present study highlight the newer therapeutic option for SMF. Exploring the old drug cysteamine can be a significant forward step towards novel treatment strategies for the treatment of SMF.
