Authors: ŞÜKÜN Abdullah , YÜKSEL ŞÜKÜN Elmas 
Published: August 2023

Aim: To describe the most common findings in orbital trauma and to support radiologic decision making by comparing them in 7 pathology regions.
Material and Methods: A total of 190 patients (119 males and 71 females) participated in the study. Orbital injury pathologies were documented and compared in seven regions. The most typical results of orbital tomography were determined. Binominal regression analysis was also performed for each trauma region.
Results: 190 orbital CT scans showed 13.7% orbital bone fractures (n=26), 7.9% bulbus pathology (n=15), 2.6% vitreous pathology (n=5), 2.1% extraocular muscle pathology (n=4), and 6.3% (n=13) retrobulbar pathology. The most common globe pathologies were lens displacement and globe rupture. Retrobulbar fat plane changes (4.2% n=8) were the most common pathology in the region. Periorbital edema was the most common periorbital disease in 86.3% of cases (n=164). When evaluated using cross-tabulations between the seven pathologic regions, the relationship between bone pathology and retrobulbar area and between globe and vitreous was statistically significant (p

Published: August 2023

Aim: Bisphenol-A (BPA) is an estrogenic chemical used today in the production of epoxy resin and as an additive in other non-polymer plastics. Due to the widespread use of BPA today, human exposure is inevitable. This exposure causes harmful effects on various body systems. The aim of this study is to investigate the effects on the development of the kidneys of the offspring of mother rats exposed to BPA during pregnancy and lactation, as a result of the offspring being exposed to BPA through the placenta and milk.
Material and Methods: In this study, 13 adult Wistar albino female rats were divided into 3 groups. In Group 1 (Control group), rats were only administered 1 ml/kg/day corn oil intraperitoneally. Group 2 (25 mg BPA group) rats were administered 25 mg/kg/day BPA; Group 3 (50 mg group) rats were administered 50 mg/kg/day BPA intraperitoneally for 5 weeks. At the end of the experiment, the intracardiac blood and kidney tissues of the offspring rats were taken and examined for urea, total protein, creatinine, TAS, TOS, MDA values.
Results: At the end of the study, it was determined that BPA increased serum urea, creatinine and total protein levels, induced the formation of reactive oxygen species causing oxidative damage in kidney tissue, and caused serious structural damages
Conclusion: Only mother rats exposed to BPA. BPA transferred to pups via placenta and milk, causing structural damage: narrowing in Bowman's space of renal corpuscle, dilatation in proximal/distal tubules and collecting ducts, occasional cell loss, vacuolization in tubule epithelia.

Abstract
The astrometric precision and accuracy of an imaging camera is often limited by geometric optical distortions. These must be calibrated and removed to measure precise proper motions, orbits, and gravitationally lensed positions of interesting astronomical objects. Here, we derive a distortion solution for the OSIRIS Imager fed by the Keck I adaptive optics system at the W. M. Keck Observatory. The distortion solution was derived from images of the dense globular clusters M15 and M92 taken with OSIRIS in 2020 and 2021. The set of 403 starlists, each containing ∼1000 stars, were compared to reference Hubble catalogs to measure the distortion-induced positional differences. OSIRIS was opened and optically realigned in 2020 November and the distortion solutions before and after the opening show slight differences at the ∼20 mas level. We find that the OSIRIS distortion closely matches the designed optical model: large, reaching 20 pixels at the corners, but mostly low order, with the majority of the distortion in the 2nd-order mode. After applying the new distortion correction, we find a median residual of [x, y] = [0.052, 0.056] pixels ([0.51, 0.56] mas) for the 2020 solution, and [x, y] = [0.081, 0.071] pixels ([0.80, 0.71] mas) for the 2021 solution. Comparison between NIRC2 images and OSIRIS images of the Galactic center show that the mean astrometric difference between the two instruments reduces from 10.7 standard deviations to 1.7 standard deviations when the OSIRIS distortion solution is applied. The distortion model is included in the Keck AO Imaging data-reduction pipeline and is available for use on OSIRIS data.

Abstract
Eta Carinae (η Car) exhibits a unique set of P Cygni profiles with both broad and narrow components. Over many decades, the spectrum has changed—there has been an increase in observed continuum fluxes and a decrease in Fe ii and H i emission-line equivalent widths. The spectrum is evolving toward that of a P Cygni star such as P Cygni itself and HDE 316285. The spectral evolution has been attributed to intrinsic variations such as a decrease in the mass-loss rate of the primary star or differential evolution in a latitudinal-dependent stellar wind. However, intrinsic wind changes conflict with three observational results: the steady long-term bolometric luminosity; the repeating X-ray light curve over the binary period; and the constancy of the dust-scattered spectrum from the Homunculus. We extend previous work that showed a secular strengthening of P Cygni absorptions by adding more orbital cycles to overcome temporary instabilities and by examining more atomic transitions. cmfgen modeling of the primary wind shows that a time-decreasing mass-loss rate is not the best explanation for the observations. However, models with a small dissipating absorber in our line of sight can explain both the increase in brightness and changes in the emission and P Cygni absorption profiles. If the spectral evolution is caused by the dissipating circumstellar medium, and not by intrinsic changes in the binary, the dynamical timescale to recover from the Great Eruption is much less than a century, different from previous suggestions.
Deuterated Polycyclic Aromatic Hydrocarbons in the Interstellar Medium: The Aliphatic C–D Band Strengths
Authors: Yang X. J. , Li Aigen 
Published: August 2023

Abstract
Deuterium (D) was exclusively generated in the Big Bang, and the standard Big Bang nucleosynthesis (BBN) model predicts a primordial abundance of D/H ≈ 26 parts per million (ppm). As the Galaxy evolves, D/H gradually decreases because of astration. The Galactic chemical evolution (GCE) model predicts a present-day abundance of D/H ≳ 20 ppm. However, observations of the local interstellar medium have revealed that the gas-phase interstellar D/H varies considerably from one region to another and has a median abundance of D/H ≈ 13 ppm, substantially lower than predicted from the BBN and GCE models. It has been suggested that the missing D atoms of D/H ≈ 7 ppm could have been locked up in deuterated polycyclic aromatic hydrocarbon (PAH) molecules. However, we have previously demonstrated that PAHs with aromatic C–D units are insufficient to account for the missing D. Here we explore if PAHs with aliphatic C–D units could be a reservoir of D. We perform quantum chemical computations of the vibrational spectra of superdeuterated PAHs (in which one D and one H share one C atom) and PAHs to which a D-substituted methyl group is attached, and derive the band strengths of the aliphatic C–D stretch (A
4.65). By applying the computationally derived A
4.65 to the observed aliphatic C–D emission at ∼4.6–4.8 μm, we find that PAHs with aliphatic C–D units could have tied up a substantial amount of D/H and marginally account for the missing D. The possible routes for generating PAHs with aliphatic C–D units are also discussed.
An Evenly Spaced LSST Cadence for Rapidly Variable Stars
Authors: Feigelson Eric D. , Bianco Federica B. , Bonito Rosaria 
Published: August 2023

Abstract
Stars exhibit a bewildering variety of rapidly variable behaviors ranging from explosive magnetic flares to stochastically changing accretion to periodic pulsations or rotation. The principal Rubin Observatory Legacy Survey of Space and Time (LSST) surveys will have cadences too sparse and irregular to capture many of these phenomena. We propose here an LSST microsurvey to observe a single Galactic field, rich in unobscured stars, in a continuous sequence of 30 s exposures for one long winter night in a single photometric band. The result will be a unique data set of ∼1 million regularly spaced stellar light curves. The light curves will constitute a comprehensive collection of late-type stellar flaring, but also other classes like short-period binary systems and cataclysmic variables, young stellar objects, and ultrashort-period exoplanets. An unknown variety of anomalous solar system, Galactic, and extragalactic variables and transients may also be present. A powerful array of statistical procedures can be applied to individual light curves from the long-standing fields of time series analysis, signal processing, and econometrics. Dozens of “features” describing the variability can be extracted and the ensemble of light curves can be subject to advanced machine-learning clustering procedures. This will give a unique, authoritative, objective taxonomy of the rapidly variable sky derived from identically cadenced light curves. This microsurvey is best performed early in the Rubin Observatory program, and the results can inform the wider community on the best approaches to variable star identification and classification from the sparse, irregular cadences that dominate the planned surveys.
The Behavior of Ap/Fp Stars in the Ultraviolet—Paper I: HD 137949 (33 Lib)
Authors: Monier Richard 
Published: August 2023

Abstract
The analysis of six spectra of the F0Vp EuGdSr star HD 137949 recorded by the SWP camera on board the International Ultraviolet Explorer does not reveal any variations of the far-ultraviolet spectral energy distribution shortwards of 1800 Å over slightly more than 2 yr and a half. The five spectra taken consecutively on 1984 February 23 do not show evidence either for rapid variations of the flux over 2 hr and 50 minutes (whereas the main pulsational period is 8.27 minutes for this rapidly oscillating Fp star). This behavior remarkably differs from the 50% flux variability of δ Scuti (F2 III) in the FUV over its 4 hr and 40 minutes period.
Do the Outburst Properties of M31N 2008-12a Depend on the Time Since the Previous Eruption?
Authors: Burris William A. , Shafter Allen W. , Hornoch Kamil 
Published: August 2023

Abstract
Photometric observations spanning the UV to the near-IR during the nine most recent eruptions (2014–2022) of the extragalactic nova M31N 2008-12a are presented and analyzed in order to explore whether the lightcurve properties for a given eruption, specifically the peak magnitudes and fade rates, are correlated with the time interval since the previous eruption. No significant correlation between the pre-eruption interval and the rate of decline was found, however it appears that the brightness at the peak of an outburst may be positively correlated with the time interval since the previous eruption.

Published: August 2023

Abstract
Activated B cells experience metabolic changes that require mitochondrial remodeling, in a process incompletely defined. In this study, we report that mitochondrial antiviral signaling protein (MAVS) is involved in BCR-initiated cellular proliferation and prolonged survival. MAVS is well known as a mitochondrial-tethered signaling adaptor with a central role in viral RNA-sensing pathways that induce type I IFN. The role of MAVS downstream of BCR stimulation was recognized in absence of IFN, indicative of a path for MAVS activation that is independent of viral infection. Mitochondria of BCR-activated MAVS-deficient mouse B cells exhibited a damaged phenotype including disrupted mitochondrial morphology, excess mitophagy, and the temporal progressive blunting of mitochondrial oxidative capacity with mitochondrial hyperpolarization and cell death. Costimulation of MAVS-deficient B cells with anti-CD40, in addition to BCR stimulation, partially corrected the mitochondrial structural defects and functionality. Our data reveal a (to our knowledge) previously unrecognized role of MAVS in controlling the metabolic fitness of B cells, most noticeable in the absence of costimulatory help.
An approach to proptosis: A review
Authors: Mishra Shreya , Sharma Luitel Sushovit , Das Sucharita , Singh Anupam 
Published: August 2023

Abstract
Proptosis is a vision-threatening condition, where abnormal protrusion of one or both eyeballs develop outwards from the orbit. Clinically, it is defined as a protrusion of the eyeball beyond 21 mm from the orbital rim or an asymmetry of more than 2 mm between both eyes. It can be classified based on onset as acute, sub-acute and chronic proptosis. The causes of proptosis can be broadly classified into infectious, inflammatory, autoimmune, endocrine, vascular, traumatic, and neoplastic entities. Quantitative measurement of proptosis is done by exophthalmometers such as Hertel’s, Luedde’s, Naugle and Gormaz exophthalmometers. Proptosis is evaluated using multiple investigations involving laboratory, ocular, radiological and histopathological studies. This article provides insight into various types, etiologies, and approaches toward the evaluation, diagnosis, and management of proptosis.

Authors: Dua Rasleen , Vashisth Pallavi , Naik Sathyajith N. , Sharma Shivangi , De Sriparna , Maheshwari Priya 
Published: August 2023

ABSTRACT

Background:
The general health and quality of life are directly correlated with oral health. Oral health is one of the unique health concerns that apply to all children. Pediatric dentistry is built on effective communication with children, which is also a requirement for providing pediatric dental care. Many pediatric dentists find it difficult to anticipate children’s behavior and how they will respond to therapeutic procedures. The purpose of this study was to evaluate children’s attachment types in order to forecast their behavior during a dentist appointment.

Materials and Methods:
The participants were 120 children between the ages of 4 and 7 who were reported to the Department of Pediatric and Preventive Dentistry, Institute of Dental Sciences, Bareilly. The youngsters were evaluated by a dental graduate student. While they waited in the waiting area, the parents were asked to complete the Kinship Center Attachment Questionnaire regarding their kids. In the second visit, dental work was scheduled for the kids who had met the requirements for inclusion in the first visit. Another pediatric dentistry postgraduate student evaluated the children’s conduct during the dental procedure using a predefined questionnaire and the Frankl scale. The Chi-squared test, t-test, Pearson’s correlation coefficient, and linear regression were used to examine the data.

Results:
According to the findings, 55.8% of the total children were cooperative, among which 59.1% were female and 52.0% were males. The average age of the kids was 6.2 ± 0.95. Moreover, 21.3% of kids had insecure attachment styles and 78.7% of kids had secure attachment types. The child–dentist communication and the insecure ambivalent attachment pattern were significantly correlated. As a result, our study demonstrated that children’s safe attachment styles varied with age. Our results showed that there is an inverse relationship between children’s collaboration and age, with cooperation rising as age increases.

Conclusions:
According to the findings of this study and considering its limitations, in young ages, the attachment style of the mother plays an important role in behavior of children. The significant correlations existed between the insecure ambivalent attachment style and child–dentist communication, as well as the secure attachment type and mother–child separation.

Published: August 2023

ABSTRACT

Background:
This study evaluated the effect of using chitosan, nano-chitosan, and ethylenediaminetetraacetic acid (EDTA) as final irrigating solutions on smear layer cleanliness and Ca/P ratio of dentin.

Methodology:
Forty-eight decoronated human single-rooted teeth were used. They were divided randomly into four groups (n = 12) based on the final irrigating solution used as follows: (a) control group (IA; n = 6) normal saline, (IB; n = 6) were left unprepared; group II - 0.2% chitosan; group III - 0.2% nano-chitosan; and group IV - 17% EDTA. Samples were prepared using ProTaper Next and irrigated with 2.6% NaOCl 5 ml after each instrument using 31-gauge needle. Final rinse was used 5 ml/3 min according to the assigned group. The specimens were prepared for evaluation.

Results:
Best smear layer removal was observed in group IV. No statistically significant differences (P > 0.05) were observed between the experimental groups (II, III, and IV) coronally; however, a statistically significant difference (P < 0.05) was observed between groups II and IV at middle and apical thirds. Intragroup comparison showed that apical third exhibited the highest mean smear layer score among all experimental groups. The highest mean Ca/P ratio was in the 0.2% nano-chitosan group, while the highest calcium loss was in the 17% EDTA group.

Conclusions:
17% EDTA is a potent chelating agent that can successfully remove the smear layer but compromises the Ca/p ratio of dentin. However, 0.2% chitosan and its nanoparticles have comparable chelating effects and induce remineralization of the root canal dentin.

ABSTRACT

Background:
Povidone Iodine (PI) is the most frequent antiseptic used as a topical disinfectant in surgery. It has been reported high transcutaneous iodine absorption due to topical PI usage, but there is a lack of data in periods of excess iodine depletion.

Materials and Methods:
This is a cross-sectional study designed to assess serial urinary iodine concentration (UIC) after topical administration of PI to evaluate the transcutaneous iodine absorption and the proper iodine depletion time for safe administration of Radio Active Iodine (RAI) therapy as ablative or adjuvant therapy.

Results:
Thirty-seven patients with papillary thyroid carcinoma undergoing total thyroidectomy were assigned to the PI group (n = 20) or chlorhexidine gluconate (CHG) group (n = 17). In the PI group, the UIC levels rose to a maximum of 2 times in the 4th week after administration and returned to pre-operative levels in the 8th week after. In the CHG group, there was a decrease in UIC levels due to a low iodine diet (LID) with a significant P-value of 0.001, <0.001, and 0.001 in the 2nd, 4th, and 8th weeks follow up respectively compared to the PI group. The urinary excretion of excess iodine lasts about 8 weeks after total thyroidectomy until iodine levels turn back to pre-operative values.

Conclusion:
If the thyroidectomy was prepared with PI, RAI is better to be performed 6-8 weeks after surgery rather than the standard prescription of 4 weeks.

Amazon Simple Storage Service (Amazon S3) is a widely used platform for storing large biomedical datasets. Unintended data alterations can occur during data writing and transmission, altering the original content and generating unexpected results. However, no open-source and easy-to-use tool exists to verify end-to-end data integrity. Here, we present aws-s3-integrity-check, a user-friendly, lightweight, and reliable bash tool to verify the integrity of a dataset stored in an Amazon S3 bucket. Using this tool, we only needed ∼114 min to verify the integrity of 1,045 records ranging between 5 bytes and 10 gigabytes and occupying ∼935 gigabytes of the Amazon S3 cloud. Our aws-s3-integrity-check tool also provides file-by-file on-screen and log-file-based information about the status of each integrity check. To our knowledge, this tool is the only open-source one that allows verifying the integrity of a dataset uploaded to the Amazon S3 Storage quickly, reliably, and efficiently. The tool is freely available for download and use at https://github.com/SoniaRuiz/aws-s3-integrity-check and https://hub.docker.com/r/soniaruiz/aws-s3-integrity-check.
