Authors: Sivaranjani S. , Annasamy Rameshkumar , James Amritha , Krishnan Rajkumar , Mahalingam Ramya , Arunachalam Preethi 
Published: December 2022

Introduction:
Free radical-induced damage on the lipids results in the creation of a novel oxidative stress marker—malondialdehyde (MDA). MDA-induced cell damage affects the immune mechanisms of saliva and may lead to the initiation and progression of bacterial diseases like periodontitis and even dental caries.

Aim and Objectives:
To determine the salivary levels of the oxidative stress marker—malondialdehyde (MDA) in subjects with dental caries before and after treatment to assess the role of MDA in the initiation and evolution of dental caries.

Materials and Methods:
The study included 40 patients in total. Based on the number of caries teeth present at the time of diagnosis, patients were divided into two groups: Group I: Subjects with dental caries in 1–2 teeth, N = 20; Group II: Subjects with dental caries in 3–4 teeth, N = 20. The patients were further divided into two groups after undergoing treatment: Group III: Group I subjects who undertook treatment for dental caries, N = 20; Group IV: Group II subjects who underwent treatment for dental caries, N = 20. The whole saliva was obtained from all subjects before treatment and one month after treatment. Estimation of MDA levels was done using ELISA. Statistical analysis was conducted using Student's t-test and Pearson's correlation coefficient. A P value ≤ 0.05 was considered significant.

Results:
Elevated levels of MDA were evident in subjects with greater carious lesions. The levels of MDA decreased significantly in post-treatment subjects. Pearson's correlation analysis also showed a strong positive correlation with the R-value of 0.832 between Group I and Group II.

Conclusion:
MDA levels increased with an increase in carious lesions and significantly reduced following treatment proving the role of salivary MDA in the evolution of dental caries.
Correlation of the Mandibular Inferior Cortical Index and Panoramic Mandibular Index on Digital Panoramic Radiographs with Total Serum Calcium and Maximum Hand-Grip Strength in the Elderly – A Prospective Study
Authors: Das Bipasha , Bagewadi Shivanand B. 
Published: December 2022

Introduction:
Panoramic radiograph classification can be used in general dental practice to identify the suspected risk of osteoporosis.

Objective:
The study aimed to compare the values of mandibular inferior cortex (MIC) classification and panoramic mandibular index (PMI) in the digital panoramic radiographs of elderly males and females to investigate whether there was a relationship between the indices and total serum calcium (TSC) and maximum hand-grip strength.

Methods:
Forty healthy elderly males and females were included in the study. The PMI and MIC were measured using a digital panoramic machine. Their TSC was evaluated, and the maximum hand-grip strength was recorded using a dynamometer. The correlation of the indices with TSC was analyzed to evaluate osteoporotic changes in the mandible.

Results:
The hand-grip strength was significantly higher in males than in females. The class 2 MIC was significantly higher compared to that in class 1 and class 3. The kappa value of the intraobserver agreement was almost perfect. The mean rank of MIC classification of females was significantly higher than that of males. The correlation among the MIC, PMI, and TSC was statistically significant.

Conclusion:
The present study showed that the MIC classification might be a better indicator/predictor for detecting early osteoporotic changes in older women.
Comparison of Oral Submucosal Thickness in Oral Submucous Fibrosis Patients before and after Treatment using Ultrasonography – A Hospital-Based Study
Authors: Sasidharan Manjima , Keluskar Vaishali K. , Bagewadi Anjana S. , Patil Santosh D. 
Published: December 2022

Background:
Oral submucous fibrosis (OMFS) is a chronic progressive, potentially malignant disorder of the oral cavity. The diagnosis is usually based on clinical findings, and normally, biopsy is not performed as it can result in scarring and worsening of the condition. The prognosis of the treatment is judged by clinical assessment, and it can vary among clinicians. Ultrasonography is a non-invasive technique used in diagnostic imaging for many decades, including oral and maxillofacial pathologies.

Aim and Objective:
The present study aimed to compare the oral submucosal thickness in OSMF patients before and after treatment using ultrasonography.

Materials and Methods:
Fifty OSMF patients were selected and recalled biweekly for two months for injecting dexamethasone and hyaluronidase intralesional injections. Each patient was subjected to ultrasonographic evaluation of oral mucosa before and at the end of treatment. Pre- and post-treatment ultrasonographic thickness of oral submucosa was compared using paired t-test.

Result:
The inference of the present study showed a reduction in the thickness of oral submucosa after treatment in OSMF. The decrease in thickness of the submucosa was statistically significant (p-value < 0.00), and also, there was a correlation between mouth opening and ultrasonographic measurements of the submucosa.

Conclusion:
Hence, ultrasonography can be used as a non-invasive tool for evaluating OSMF by comparing the change in the thickness of submucosa before and after treatment.

Published: December 2022

Background
Diabetes mellitus impairs the reproduction functions through induction of oxidative stress. Genistein is a nonsteroidal estrogenic isoflavone that has been found in plants as soybean. It has controversial effects on male reproductive functions.

Aim
This study was designed to explore the effect of genistein on reproductive function in male diabetic rats.

Materials and methods
Fifty adult male Wistar rats were divided into five equal groups: control group, diabetic control group, diabetic treated with genistein 10 mg/kg intraperitoneally (Gen10) group, diabetic treated with genistein 50 mg/kg (Gen50) group, and diabetic treated with genistein 100 mg/kg (Gen100) group. At the end of the experiment, body weight and food intake were determined. The collected blood samples were used for determination of serum glucose, insulin, testosterone, follicle-stimulating hormone, and luteinizing hormone levels. Also, sperm count, viability, motility, and testicular weight were determined. In addition, testicular caspase-3, malondialdehyde, glutathione peroxidase, and catalase were determined.

Results
In the diabetic group, there was significant deterioration of the studied parameters. All the studied parameters in Gen50 and Gen100 groups were significantly improved as compared with the Gen10 group.

Conclusion
Genistein ameliorated the reproductive dysfunction in diabetic male rats through improving glycemic state, insulin secretion, in addition to its antioxidant, and anti-apoptotic effect on testicular tissue.

Published: December 2022

Background
Regional anesthesia has an advantage over general anesthesia, as it is a simple, effective block, economical, and safe.

Aim
The aim of this study was to evaluate the value of epidural volume extension (EVE) on sensory and motor blockade in patients undergoing hip surgeries using combined spinal epidural (CSE) anesthesia.

Patients and methods
This study was carried out on 90 adult patients of both sexes with physical status American Society of Anestheologists I–II–III scheduled for hip surgeries and admitted at Tanta University Hospitals in the Orthopedic Department.

Results
In this study, 90 patients were randomly allocated into two groups (45 patients in each one): group I: received CSE only. Group II: received CSE with EVE. We found that intraoperative arterial blood pressure decreased significantly in group I than group II at 135 min (P≤0.001), intraoperative heart rate showed a significant increase in group I than group II at 135 min (P=0.022), significantly, a higher number of patients in group II reached a higher level of sensory blockade than group I, the duration of sensory and motor block showed a significant decrease in group I than group II (P<0.001), time for maximum sensory and motor block showed a significant increase in group I than group II (P<0.001), two-segment regression time and time to recover from motor block showed a significant decrease in group I than group II (P=0.028, P<0.001, respectively), and an insignificant difference between both groups as regarding to adverse effects.

Conclusions
CSE anesthesia with EVE is superior to CSE alone in hip surgeries as regarding to duration, level of motor and sensory block with slight affection of hemodynamic status, and indifferent as regarding to postoperative adverse effects.

Published: December 2022

Background
Liver fibrosis proceeds to portal hypertension, and portal hypertensive gastropathy is considered its main complication. Olive oil is associated with human health benefits.

Aim
To study the effect of olive oil on the stomach after induction of liver fibrosis.

Materials and methods
A total of 50 healthy adult male albino rats were randomly divided into two groups, including group I (control group) and group II (experimental group), which were subdivided into four subgroups: olive oil-treated subgroup IIa received 5 ml/kg body weight olive oil daily by an orogastric tube for 4 weeks, subgroup IIb received 0.1 ml/100 g body weight carbon tetrachloride (CCL4) by intraperitoneal injection twice per week for 4 weeks, subgroup IIc received both olive oil and CCL4 at the same dose of subgroups IIa and IIb for the same period, and subgroup IId received CCL4 for 4 weeks and then olive oil was given alone for another 4 weeks as the same dose in subgroups IIa and IIb. Stomach specimens were processed for histological and immunohistochemical study.

Results
Subgroup IIb showed disorganized and atrophic gastric glands with severe interstitial hemorrhage and diffuse inflammatory infiltrates. The parietal cells had vacuolated cytoplasm with irregular nuclei, and others had karyolitic nuclei with vacuolization of the cytoplasm of some chief cells. Subgroup IIc showed significant improvement, and subgroup IId showed nonsignificant improvement.

Conclusion
The use of olive oil partially improved the histological changes in the stomach as a result of liver fibrosis.
L’habit fait-il le dieu ? Gestes et parures autour des hermes priapiques dans les images romaines
Authors: WYLER Stéphanie 
Published: December 2022

Résumé

Les paysages dits sacro-idylliques présentent une relativement grande variété de scènes figurant des personnages mineurs occupés à vêtir, parer de guirlandes, charger d’offrandes des statues hermaïques, dont la seule caractéristique « à nu » est d’être phallique. Le dispositif rituel ainsi mis en image confère au pilier hermaïque davantage qu’une actualisation performative dans le cadre du geste cultuel, il lui donne son identité. Nous étudions ces processus dans la peinture, les stucs, la glyptique et la toreutique de la fin de la République et du début de l'Empire, confrontés à la poésie dite priapique et à sa traduction dans la poésie élégiaque contemporaine.

Abstract

Title: Do clothes make the god? Gesture and adornments linked to rustic herms in Roman images

The so-called sacro-idyllic landscapes present a relatively wide variety of scenes depicting minor figures engaged in clothing, adorning with garlands, loading with offerings Hermaic statues, the only characteristic of which before being dressed is to have a phallus. The ritual system designed like that confers to the Hermaic pillar more than a performative agency during the cult, it gives to it its actual identity. I study these processes in paintings, stuccoes, glyptics and toreutics dating back from the end of the Republic and the beginning of the Empire, in comparison with the so-called Priapic poetry, and its translation into contemporary Elegiac poetry.

Dural splitting has similar therapeutic efficacy with less complications, shorter operative and hospitalization times when compared to duraplasty in chiari type-I malformation
Authors: GÜN Eren Görkem , GÜL Şanser 
Published: December 2022

Background: A standard surgical technique has not been developed for Chiari Type-1 malformation. Recently, dural-splitting has also been introduced in addition to duraplasty. We aimed to determine both surgical techniques’ advantages/disadvantages clinically and radiologically.
Material and Method: We retrospectively evaluated 28 patients’ data with Chiari Type-I malformation and operated at the Neurosurgery Department of Bülent Ecevit University between January 2014 and April 2018. We retrieved demographic characteristics, symptoms, physical/neurological findings, preoperative/postoperative imaging data/measurements, VAS, Chicago Chiari Outcome Scale, Neck Disability Index, Neurological Scoring System, and modified-JOA scores, operation and hospitalization times, and complications from the automation system.
Results: Patients’ mean age was 38.5±13.0 years, and female/male ratio was 2.1/1. Syringomyelia was present in half of all cases. Mean tonsil herniation length was 11.64±4 mm, and mean tonsillo-dural distance was 4.18±1.7 mm. There were no significant relationships between tonsil herniation length and syringomyelia, and between tonsillo-dural distance and clinical improvement. Posterior fossa decompression was initially performed in all patients. Then, in 17 patients, duraplasty was performed. In 11 patients, dural-splitting was used. No significant differences were determined between duraplasty and dural-splitting regarding VAS, Chicago Chiari Outcome Scale, Neck Disability Index, Neurological Scoring System, and modified-JOA scores. Significant differences were present, favoring dural-splitting regarding operation time, hospital stay, and complication rates.
Conclusion: Posterior fossa decompression/duraplasty is an effective surgical technique to treat Chiari Type-I malformation. Posterior fossa decompression/dural-splitting is an optimal surgical alternative with a lower complication rate, shorter operation time, and hospitalization period.

Published: December 2022

Speech Neuroprostheses have the potential to enable communication for people with dysarthria or anarthria. Recent advances have demonstrated high-quality text decoding and speech synthesis from electrocorticographic grids placed on the cortical surface. Here, we investigate a less invasive measurement modality in three participants, namely stereotactic EEG (sEEG) that provides sparse sampling from multiple brain regions, including subcortical regions. To evaluate whether sEEG can also be used to synthesize high-quality audio from neural recordings, we employ a recurrent encoder-decoder model based on modern deep learning methods. We find that speech can indeed be reconstructed with correlations up to 0.8 from these minimally invasive recordings, despite limited amounts of training data.
Interaction between cloud–radiation, atmospheric dynamics and thermodynamics based on observational data from GoAmazon 2014/15 and a cloud-resolving model
Authors: Gonçalves Layrson J. M. , Coelho Simone M. S. C. , Kubota Paulo Y. , Souza Dayana C. 
Published: December 2022

Abstract. Observational meteorological data from the field
experiment GoAmazon 2014/15 and data from numerical simulations with the
cloud-resolving model (CRM) called the System for Atmospheric Modeling (SAM) are
used to study the interaction between the cloudiness–radiation as well as the
atmospheric dynamics and thermodynamics variables for a site located in the
central Amazon region (−3.2∘ S, −60.6∘ W) during the wet
and dry periods. The main aims are to (a) analyze the temporal series of the
integrated cloud fraction, precipitation rate and downward shortwave flux
as well as (b) to determine the relationship between the integrated cloud fraction,
radiative fluxes and large-scale variable anomalies as a function of the
previous day's average. The temporal series of the integrated cloud
fraction, precipitation rate and downward shortwave flux from SAM
simulations showed physical consistency with the observations from GoAmazon
2014/15. Shallow and deep convection clouds show to have a meaningful impact
on radiation fluxes in the Amazon region during wet and dry periods.
Anomalies of large-scale variables (relative to the previous day's average)
are physically associated with cloud formation, evolution and dissipation.
SAM consistently simulated these results, where the cloud fraction vertical
profile shows a pattern very close to the observed data (cloud type).
Additionally, the integrated cloud fraction and large-scale variable
anomalies, as a function of the previous day's average, have a good
correlation. These results suggest that the memory of the large-scale
dynamics from the previous day can be used to estimate the cloud fraction as
well as the water content, which is a variable of the cloud itself. In
general, the SAM satisfactorily simulated the interaction between
cloud–radiation as well as dynamic and thermodynamic variables of the atmosphere
during the periods of this study, being able to obtain atmospheric
variables that are impossible to obtain in an observational way.

Published: December 2022

Abstract. The radiogenic isotope compositions of strontium (Sr) and
neodymium (Nd) on the surface of the Earth are powerful tools for tracing
dust sources and sinks on the Earth's surface. To differentiate between the
spatial variabilities in eolian dust sources in key cryospheric regions at
the three poles (the Arctic; Antarctica; and the “third pole”, covering the high mountainous
area in Asia), a dataset of Sr–Nd isotopic
compositions from extremely cold or arid terrestrial environments was
compiled, similar to the method of Blanchet (2019). The database includes Holocene
and Quaternary
snow, ice, sand, soil (loess), sediment, and rock samples from the three poles based on 90 different references
and our own measurement data, with a total of 1989 data points, comprising 206 data
points with different grain sizes and 212 data points with fraction
measurements. There are 485 data points from the third pole, 727 data points
from the Arctic, and 777 data points from Antarctica. The sampling and
measurement methods of these data are introduced. For each pole,
geographical coordinates and other information are provided. The main
scientific purpose of this dataset is to provide a Sr–Nd dataset based on
collective documentation and our own measurements, which will be useful for
determining the sources and transport pathways of dust in snow, ice, rivers,
and oceans at or near the three poles as well as to investigate whether multiple
dust sources are present at each of the poles. This dataset provides
exhaustive detailed documentation of the isotopic signatures at the three
poles during specific time intervals in the Quaternary period, which are
useful for understanding the sources or sinks of eolian dust and sediments
at the three poles. The dataset is available from the National Tibetan
Plateau Data Center (https://doi.org/10.11888/Cryos.tpdc.272100, Du,
2022).
