Abstract
Stellar parameters for large samples of stars play a crucial role in constraining the nature of stars and stellar populations in the Galaxy. An increasing number of medium-band photometric surveys are presently used in estimating stellar parameters. In this study, we present a machine learning approach to derive estimates of stellar parameters, including [Fe/H], log g, and T
eff, based on a combination of medium-band and broadband photometric observations. Our analysis employs data primarily sourced from the Stellar Abundances and Galactic Evolution Survey (SAGES), which aims to observe much of the Northern Hemisphere. We combine the uv-band data from SAGES DR1 with photometric and astrometric data from Gaia EDR3, and apply the random forest method to estimate stellar parameters for approximately 21 million stars. We are able to obtain precisions of 0.09 dex for [Fe/H], 0.12 dex for log g, and 70 K for T
eff. Furthermore, by incorporating Two Micron All Sky Survey and Wide-field Infrared Survey Explorer infrared photometric and Galaxy Evolution Explorer ultraviolet data, we are able to achieve even higher precision estimates for over 2.2 million stars. These results are applicable to both giant and dwarf stars. Building upon this mapping, we construct a foundational data set for research on metal-poor stars, the structure of the Milky Way, and beyond. With the forthcoming release of additional bands from SAGES such DDO51 and Hα, this versatile machine learning approach is poised to play an important role in upcoming surveys featuring expanded filter sets.

Published: February 2025

Abstract
This study focuses on transforming galaxy images between astronomical surveys, specifically enhancing images from the Sloan Digital Sky Survey (SDSS) and the Dark Energy Camera Legacy Survey (DECaLS) to achieve quality comparable to the Hyper Suprime-Cam (HSC) Survey. We proposed a hybrid model called Pix2WGAN, which integrates the pix2pix framework with the Wasserstein generative adversarial network with gradient penalty to convert low-quality observational images into high-quality counterparts. Our model successfully transformed DECaLS images into pseudo-HSC images, yielding impressive results and significantly enhancing the identification of complex structures, such as galaxy spiral arms and tidal tails, which may have been overlooked in the original DECaLS images. Moreover, Pix2WGAN effectively addresses issues like artifacts, noise, and blurriness in both source and target images. In addition to the basic Pix2WGAN model, we further developed an advanced architecture called Cascaded Pix2WGAN, which incorporates a multistage training mechanism designed to bridge the quality gap between SDSS and HSC images, demonstrating similarly promising outcomes. We systematically assessed the similarity between the model-generated pseudo-HSC images and actual HSC images using various metrics, including root mean squared error, peak signal-to-noise ratio, and structural similarity index, along with perceptual metrics such as learned perceptual image patch similarity and Fréchet inception distance. The results indicate that images transformed by our model outperform both the original SDSS and DECaLS images across nearly all evaluation metrics. Our research is expected to provide significant technical support for astronomical data analysis, cross-survey image integration, and high-precision astrometry.

Published: February 2025

Abstract
Interstellar molecules, which play an important role in astrochemistry, are identified using observed spectral lines. Despite the advent of spectral analysis tools in the past decade, the identification of spectral lines remains a tedious task that requires extensive manual intervention, preventing us from fully exploiting the vast amounts of data generated by large facilities such as the Atacama Large Millimeter/submillimeter Array. This study aims to address the aforementioned issue by developing a framework for automated line identification. We introduce a robust spectral fitting technique applicable to spectral line identification with minimal human supervision. Our method is assessed using published data from five line surveys of hot cores, including W51, Orion-KL, Sgr B2(M), and Sgr B2(N). By comparing the identified lines, our algorithm achieves an overall recall of ∼74%–93%, and an average precision of ∼78%–92%. Our code, named spectuner, is publicly available on GitHub.
Jacques Roger, Ernst Mayr et l’histoire de la théorie de l’évolution. Science et idéologie dans les sciences biologiques
Authors: Méthot Pierre-Olivier 
Published: February 2025

Spécialiste de l’histoire de la pensée biologique au xviiie siècle, c’est au transformisme et en particulier à l’œuvre de Darwin, à sa réception et à ses prolongements théoriques récents que l’historien Jacques Roger (1920-1990) se consacre du début des années 1970 jusqu’à son décès. Comment rendre compte de ce tournant vers l’histoire de la théorie de l’évolution et de la biologie du xxe siècle ? Selon l’hypothèse envisagée ici, ce sont les rencontres de Roger avec les historiens et les biologistes anglo-saxons, et notamment avec Ernst Mayr, qui ont façonné son intérêt envers l’histoire de la théorie de l’évolution, dont il refusait de séparer les dimensions scientifique et socioculturelle. Plus fondamentalement, comme le révèle un manuscrit inédit récemment retrouvé, si Roger s’intéressa à la théorie darwinienne de l’évolution, c’est aussi parce qu’elle soulève à nouveaux frais des enjeux importants liés à la question de « l’homme ».

Authors: You Yu-Lai , Zheng Sheng , Zhao Cheng-Jian , Chang Ye-Fei , Liu Pei , Zeng Xue-Li , Liu Lian 
Published: February 2025

Objective:
To investigate the protective effects of Lepidium draba L. (L. draba) on cyclophosphamide (CP)-induced hepatotoxicity and nephrotoxicity in rats.

Methods:
A total of 36 rats were divided into six groups as follows: the sham control group, the CP group (CP 100 mg/kg i.p. on days 1, 7, 14, 21, 28, and 35), the CP groups treated with L. draba extract (100, 200 and 400 mg/kg of L. draba extract for 28 d), and the L. draba extract alone group (400 mg/kg of L. draba extract for 28 d). Serum parameters of renal and hepatic function, as well as pro-inflammatory and anti-inflammatory cytokines associated with liver and kidney damage were measured. Moreover, Bax, Bcl-2, and caspase-3 gene expression and histopathological changes were assessed.

Results:

L. draba extract alleviated CP-induced hepatotoxicity and nephrotoxicity by decreasing nitric oxide, TBARS, IL-6, TNF-α, and IL-Ιβ levels, as well as increasing superoxide dismutase, catalase and glutathione peroxidase activities, and FRAP, MIF, and TGF-β levels. In addition, the extract downregulated the expression of pro-apoptotic genes (Bax and caspase-3) and mitigated the destruction of glomeruli and renal tubules as well as the degeneration of hepatocytes.

Conclusions:

L. draba extract can protect hepatic and renal structure and function against CP-induced toxicities, and may be used as a therapeutic agent for CP-induced hepatotoxicity and nephrotoxicity.

Published: February 2025

Background:
Cleft lip and /or palate affects speech production skills. To enable uniformity in reporting the speech outcomes in individuals with cleft lip and/. or palate, universal parameters were formulated.

Aim:
To develop and validate test (word) stimuli in Malayalam, for the evaluation of speech outcomes (hypernasality, audible nasal air emission, and/or turbulence and consonant production errors) in children with cleft palate based on the guidelines reported by Henningsson et al.

Materials and Method:
The study was carried out in two phases. The first phase involved the development of the word list and content validation by parents, primary school teachers, and speech-language pathologists. The second phase involved establishing the construct validity of the word list by administering it to children with cleft lip and palate.

Results:
From the 351 words chosen from textbooks, storybooks, and picture books of children; 170 words had obtained a familiarity rating of greater than 80%. However, the word list desired to be used during clinical practice can be restricted to 44 words with 10 words representing high vowels, three words representing low/mid vowels, and 31 words representing pressure consonants.

Conclusions:
Developing test stimuli in the vernacular language, Malayalam for describing speech outcomes in children with cleft palate would aid in designing a customized management plan and effectively delivering it.

Published: February 2025

Background:
Cleft lip and/or palate (CLP) malformation represents an important health problem in Mexico that does not cause morbidity but causes important sequelae ranging from the affectation in the child’s image to functional, social, psychological, and learning problems, involving parents and the surrounding environment.

Design:
The present research had a descriptive and correlational cross-sectional design and was developed under a quantitative methodology.

Participants:
Ninety-three children, 53 (57%) male and 40 (43%) female, with a mean age of 9.6 years.

Outcome Measures:
The Piers–Harris self-concept scale and report card of the concluded school year were used.

Results:
It was found that the results of the global self-concept, as well as two of its dimensions (adjustment behavior, intellectual state), resulted to have a significant positive correlation (P < 0.01). That is, high self-concept is associated with high academic achievement, better adjustment behavior is associated with higher academic achievement and higher intellectual status is associated with high academic achievement, while other two dimensions (popularity and happiness and satisfaction) showed a low positive relationship.

Conclusions:
The results found in this research are relevant for the knowledge and explanation of the different psychosocial factors that are present in the socioemotional and academic development of the child with CLP and his family, being a population in Mexico little studied in terms of emotional, psychological and educational sequelae.

ABSTRACT

Goal:
To evaluate the knowledge and practices of oral health among Jazan, Saudi Arabian carers for people with special needs.

Methods:
Jazan Special Needs Center carers participated in a cross-sectional study. A self-administered questionnaire covering demographics, oral health behaviors, frequency of dental visits, and information sources was used to gather data. Descriptive statistics and Chi-square tests for relationships were used in the statistical study.

Findings:
Of the 157 carers who took part, 70.1% were men and 29.9% were women. The bulk of carers knew the fundamentals of good oral hygiene, however, there were misconceptions regarding fluoride and the value of routine dental checkups. For information, the majority of carers turned to dentists and the media. The degree of education and oral health knowledge of carers were significantly correlated (P < 0.05).

Conclusion:
In conclusion, Jazan carers are somewhat aware of oral health issues. To enhance oral health outcomes for people with special needs, educational interventions aimed at carers are required. These interventions should emphasize the advantages of fluoride and frequent dental check-ups.

Published: February 2025

ABSTRACT

Background:
Encouraging fair access to dental treatment and resolving gaps in oral health depend on public health dentistry. The impact of new paradigms and evidence-based practices in public health dentistry on oral health outcomes across a range of communities is examined in this study.

Methods:
A number of community health centers participated in this prospective study. Six hundred participants from a range of backgrounds were divided into intervention and control groups for the study. While the control group received normal dental treatment, the intervention group received teledentistry services, school-based oral health programs, and community water fluoridation. Over the course of a year, information on oral health outcomes, such as dental caries, periodontal illnesses, and oral hygiene habits, was gathered and examined.

Findings:
When compared to the control group, the intervention group’s oral health outcomes showed a considerable improvement. Fluoridating community water decreased the prevalence of dental cavities by 35%. Programs used in schools increased dental hygiene, while teledentistry expanded access to dental treatment, particularly in remote locations.

Conclusion:
In public health dentistry, evidence-based procedures and new paradigms greatly enhance oral health outcomes. In order to lessen inequities in oral health and advance the general health of the community, these interventions ought to be included in public health programs.

Published: February 2025

ABSTRACT

Introduction:
This study aims to compare patient-reported outcomes (PROs) between clear aligners and conventional fixed braces. Orthodontic treatments not only focus on functional outcomes but also patient satisfaction, comfort, and aesthetics. Understanding PROs can guide treatment decisions for better patient-centered care.

Methods:
A comparative study involving 150 orthodontic patients treated with either clear aligners or conventional braces was conducted. The PROs evaluated included comfort, aesthetics, oral hygiene maintenance, and speech impairment. Surveys were administered at the beginning and at regular intervals during treatment. Data were analyzed using statistical tests to compare the two groups.

Results:
Clear aligners showed superior outcomes in comfort and aesthetics, with a significant difference (P < 0.05) compared to fixed braces. Patients with conventional braces reported more difficulties with oral hygiene and speech. However, both groups had similar overall treatment satisfaction.

Conclusion:
Clear aligners are associated with higher comfort and aesthetic satisfaction, while conventional braces may be less favorable in terms of hygiene and speech. PROs play a crucial role in orthodontic treatment selection, emphasizing the need for personalized approaches based on patient preferences.

Published: February 2025

ABSTRACT

Background:
Children under the age of 6 years have their dental health affected by “Early Childhood Caries (ECC),” which is still a common public health concern. Because fluoride varnish can remineralize enamel and suppress bacterial development, it has emerged as a viable preventative strategy.

Objective:
Using patient data from a tertiary care center from January 1, 2015, to December 31, 2020, this retrospective research attempts to assess the effect of fluoride varnish treatment programs on ECC incidence and severity.

Methods:
Children between the ages of 0 and 6 years who had fluoride varnish applied during regular dental appointments met the inclusion criteria. Data on ECC diagnosis, severity, frequency of use of fluoride varnish, and demographics were retrieved.

Results:
A demographic analysis showed that the population was mostly Caucasian. Applications of fluoride varnish showed a dose–response association with ECC incidence, meaning that an increase in application frequency resulted in a substantial decrease in ECC (P < 0.05).

Conclusion:
In summary, regular use of fluoride varnish shows promise in lowering the frequency of enamel chipping, highlighting the significance of preventative actions. To achieve equitable oral health outcomes for children, it is imperative to implement strategies aimed at improving program accessibility and optimizing efficacy.

ABSTRACT

Background:
A range of disorders affecting the temporomandibular joint are referred to as temporomandibular joint disorders (TMDs), and they are treated differently and have different clinical manifestations. In order to offer an epidemiological analysis of TMD in a tertiary care setting, this study will concentrate on clinical traits and trends in therapy.

Methods:
Data from a tertiary care facility was retrospectively analyzed for the years 2017–2022. Data covered included demographics, clinical presentation, imaging results, and management approaches for a total of 200 individuals with TMD diagnoses. The data was interpreted using association analysis and descriptive statistics.

Findings:
70% of the participants were female, with a mean age of 42 years. The most common complaint was jaw discomfort (80%), and imaging tests revealed osteoarthritis (30%) and joint effusion (50%). Sixty percent of management patterns showed a preference for conservative measures, such as physical therapy and patient education.

Conclusion:
In summary, this research offers a thorough understanding of the management practices and epidemiology of TMD in a tertiary care context. The results highlight the need of tailored strategies for managing TMDs and the requirement of comprehending clinical presentations for the best possible patient treatment. In order to improve diagnostic and treatment approaches for this complex illness, further investigation is necessary.
