Abstract
Fragile X Syndrome (FXS) is the most common cause of inherited intellectual disabilities and the most prevalent monogenic cause of autism. Although the knockout (KO) of the Fmr1 gene homolog in mice is primarily used for elucidating the neurobiological substrate of FXS, there is limited association of the experimental data with the pathophysiological condition in humans. The use of Fmr1 KO rats offers additional translational validity in this regard. Therefore, we employed a multi-level approach to study the behavioral profile and the glutamatergic and GABAergic neurotransmission status in pathophysiology-associated brain structures of Fmr1 KO rats, including the recordings of evoked and spontaneous field potentials from hippocampal slices, paralleled with next generation RNA sequencing (RNA-seq). We found that these rats exhibit hyperactivity and cognitive deficits, along with characteristic bidirectional glutamatergic and GABAergic alterations in the prefrontal cortex and the hippocampus. These results are coupled to affected excitability and local inhibitory processes in the hippocampus, along with a specific transcriptional profile, highlighting dysregulated hippocampal network activity in KO rats. Overall, our data provide novel insights concerning the biobehavioral profile of FmR1 KO rats and translationally upscales our understanding on pathophysiology and symptomatology of FXS syndrome.

Abstract
Backgrounds: Stathmin 2 (STMN2) is involved in microtubule dynamics and signal transduction. Highly expressed STMN2 has been reported in various tumors. And yet its role in Thyroid carcinoma (THCA) remained unexplored. Methods: The expressed status of STMN2 in pan-cancer including THCA was evaluated using the TCGA and GETx dataset. Furthermore, the association of STMN2 with the clinical phenotypes was visualized based on TCGA-THCA clinical samples. Gene set enrichment analysis (GESA) was used to enrich STMN2-related signaling pathways. The THCA cell proliferation were examined when STMN2 overexpression or knockout. In vivo assays were undertaken to verify the impact of STMN2 knockout on THCA tumor growth. Luciferase reporter assays were conducted to determine whether STMN2 exerted its role through NF-κB signaling pathway. Results: STMN2 expression levels were differentiated in different cancers. We found that STMN2 was richly expressed in THCA patient-derived specimens based on bioinformatics anlaysis. Functionally, STMN2 enforced expression hastened the THCA cell proliferation, while CRISPR-cas9 depletion of STMN2 retarded tumorigenesis in vitro and in vivo. Mechanically, highly expressed STMN2 increased NF-κB transcriptional activity as well as accumulated IκBa expression in THCA cells, while STMN2 knockout presented an opposite phenomenon. However, PDTC exposure almost abrogated the increased IκBa expression in STMN2-overexpressing THCA cells. Conclusion: we found STMN2 is an oncogenic driver of THCA by activating NF-κB signaling pathway, potentially paving an alternative avenue for THCA management.
Effect of laser abrasive belt processing on surface quality of titanium alloy TC17Effect of laser abrasive belt processing on surface quality of titanium alloy TC17

Abstract
Due to its low thermal conductivity, work hardening and other characteristics, titanium alloys are prone to shortcomings such as large cutting force and poor processing quality in the processing process. Laser-assisted grinding (LAG) can significantly improve its processing performance, but the mechanism of synergistic parameters between laser and abrasive belt on surface quality has not been clearly revealed in the laser-assisted belt grinding process. Based on this, this paper proposes a method of laser-belt collaborative processing (LBCP), established a mathematical model of laser and abrasive belt co-processing, and reveals the collaborative processing mechanism. Through the LBCP experiment of titanium alloy TC17, the grinding force, surface morphology, and roughness of titanium alloy TC17 were investigated, and the effect of different collaborative processing factors on the surface quality of titanium alloy was studied. The results show that appropriately increasing the normal pressure will improve the surface quality of titanium alloy. The larger the laser incidence angle, the better the surface quality. Reducing the synergistic distance between the laser and the abrasive belt improves the surface quality. This study provides new ideas for laser-assisted processing of difficult-to-process materials.

Abstract

Background Statistical epistasis, a significant “gene interaction” in genetic association studies, means the nonadditive effects between the polymorphic sites on two different genes affecting the same phenotype. In genetic association analysis of complex traits, nevertheless, the researchers haven’t found statistical epistasis so far.Methods To explore the fundamental reason for this question, this study developed a modeling and computational method focusing on the statistical power and then calculated and compared the statistical power under different hypothesis testing scenarios.Results The results showed that under the parameters of large-scale genetic association analysis like genome-wide association studies, the power of the hypothesis test for detecting the statistical epistasis between different genetic marker genes was close to zero. From the results of this investigation, we can conclude that the lack of statistical epistasis in genetic association studies is an inevitable result owing to the statistical principles of the genetic association studies and the inherent characteristics of the research methods, which cannot be changed by the innovation of technical means.Conclusions It is time-consuming and hopeless to seek for the statistical epistasis in genetic association analysis of complex traits without decomposing complex traits of multiple genes into intermediate traits.

Published: July 2023

Abstract
Phosphorus (P) is the key nutrient thought to limit primary productivity on geological timescales, and hence P bioavailability exerted a major influence on Earth surface oxygenation dynamics through the Precambrian, with ensuing implications for biological evolution. Here, we document highly elevated P contents in non-glacial Ediacaran (635 − 541 Ma) iron formations from Northwestern China, with P dominantly occurring as carbonate fluorapatite formed during early diagenesis. These analyses, in combination with marine sediment P contents and phosphorite abundance data, point to a state change in oceanic P concentrations during the Ediacaran, which we attribute to enhanced recycling from marine sediments under redox stratified conditions. Subsequent elevated rates of primary productivity and organic carbon production may have sustained the contemporaneous first appearance of complex deep marine habitats, and would have increased the extent and stability of surface water oxygen concentrations, leading to conditions conducive to the subsequent evolution of more complex animals.

Authors: Bagheri-Josheghani Sareh , Saba Mohammadali , Ziloochian Azam 
Published: July 2023

Abstract
Background
Refeeding syndrome (RS) could be a serious and deadly complication of anorexia nervosa (AN). This disease is associated with electrolyte abnormalities and organ damage, which occurs with a transition from a long-term catabolic to an anabolic state, especially with excessive nutrient intake.
Case presentation
This is a case report of a 21-year-old girl admitted to Beheshti hospital in Kashan, Iran, with general fatigue, secondary amenorrhea, aggression, and constipation. Based on clinical signs and DSM-5 criteria, the patient was diagnosed with serious anorexia nervosa (AN). She was carefully taken care of, and particular attention was paid to her food. Heart failure, hypophosphatemia, and hypokalemia occurred in spite of careful treatment. Laboratory examinations and clinical signs revealed refeeding syndrome. To treat refeeding syndrome, a 40 kcal/kg regimen was prescribed for the patient. She was carefully treated, and special attention was paid to prevent early dehydration syndrome, so that her body weight and electrolyte condition increased satisfactorily.
Conclusions
Therefore, strict adherence to recommendations and careful monitoring of refeeding should always be taken into consideration when feeding patients with AN.

Abstract
The subject of this article is the Charon coins found in Chamber Tomb 5 in the Eastern Necropolis of Parion. Fourteen coins belonging to Coela (2), Perinthos (1), and Parion (11) were found in Parion Chamber Tomb 5, where 33 individuals were buried. There is a wide date range of about three centuries between the earliest and latest mints of the 14 Charon coins found in Chamber Tomb 5. All 14 Charon coins dated between 45 BC and 253–268 AD are Roman provincial coins. The first remarkable point about the 14 coins found in Room Tomb 5 is that 11 are Parion’s own mints. An analysis of the Charon coins found in the other Chamber Tombs and Necropolis areas in Parion revealed that almost 90% of the coins are Parion’s own mints. This indicates that the Parionites mostly preferred to leave their own coins in the tomb as Charon coins. Another remarkable point about the coins of Parion Chamber Tomb 5 is that although the coins represent a period of three centuries, the coins of Iulius Caesar and Claudius I, which are the earliest dated coins found in the tomb, were quite worn compared to the other coins. Therefore, these coins may have been placed in the tomb after being in circulation for a long time. Except for these two coins, the other coins found in Chamber Tomb 5 are dated between the reigns of Antoninus Pius and Gallienus. When the anthropological, archaeological and numismatic data from Chamber Tomb 5 are evaluated together, it becomes evident that 33 individuals were buried in the tomb at different times over about a century.

Abstract
During the pandemic period, the interest in not well-known, colourful wild small fruits has increased due to their positive health effects. Within the context of the current study, eleven genotypes of the rosehip, one of these fruits, grown in nature from seeds were characterized in terms of their horticultural characteristics. As a result; fruit width, fruit length and fruit weight were found to vary between 12.96–17.25 mm; 20.74–25.49 mm and 1.39–2.72 g, respectively. While citric acid was determined as the main organic acid in all the genotypes investigated, the mean values of the examined organic acids obtained from all the genotypes were found to be as follows; citric acid (7177 mg L− 1)>, malic acid (3669 mg L− 1) > tartaric acid (1834 mg L− 1) > oxalic acid (1258 mg L− 1) > carboxilic acid (631.9 mg L− 1) > shikimic acid (157.8 mg L− 1) > ascorbic acid (155 mg L− 1) > acetic acid (20.9 mg L− 1). Ellagic acid is the dominant phenolic, measured at high levels (90.1–96.24 mg L− 1) in all the genotypes. Genotypes are categorized according to different purposes such as suitable for wine, vinegar making etc. While the pomological characteristics were determined in a high level of positive correlation among themselves, they were generally found to be negatively correlated with the phytochemical characteristics. It is thought that genotypes categorized according to different usage purposes can contribute to rosehip agriculture, industry and breeding.

Abstract
Background Rapid and accurate detection of tassels is of great significance for maize breeding, seed production and the acquisition of key growth stage. To liberate manpower and improve the efficiency of production management, many automatic detection methods with acceptable accuracy have been proposed. However, images acquisition parameters of these methods were quite different, so they cannot provide an operable standard for practical applications. In this study, based on multi-temporal unmanned aerial vehicle (UAV) RGB images with maize flowering stage, we created UAV Maize Tassel Detection (UAVMTD) dataset, and used Faster R-CNN to answer what are the key factors affecting detection accuracy from two aspects of efficient use of samples and data acquisition standards. Based on the detection results, we estimated tasseling date of different plots and analyzed varieties’ differences.
Results The results show that model performance would not be greatly affected before the amount of training data changed by orders of magnitude, but it can be improved effectively by adjusting sub-images’ sizes, and the final model was selected with AP@0.5IOU was 0.916; images obtained at 12 pm were more suitable for tassels detection, AP@0.5IOU, recall and precision were 3%, 2% and 6% higher than that at 8 am; optimal spatial resolution was around 1cm for tassels detection by considering the recognition effect and data acquisition efficiency.
Conclusions This study analyzed key factors affecting maize tassels detection and provided a reasonable reference for future applications, which is helpful to screen out varieties from large-scale breeding materials.

Abstract
The changes in land use and land cover are the most considerable factors for the decision makers, which can be precisely evaluated by using Geographic Information System (GIS) and Satellite Remote Sensing (SRS) technique. The present study was carried out in the Quetta Basin Watershed for evaluating the land use change of two decades during 1999-2009 and 2009-2018, using the Landsat imageries. The main land use types of study area include water body, agriculture, vegetation, barren and built-up land area. All these land use types were mapped for each time period. The technique of hybrid classification was used for the classification of the imageries by using ISODATA and Maximum Likelihood Algorithm (MLA) in ERDAS Imagine software 2011 v, while change detection maps of different land use land cover classes was generated by using the ArcGIS 10.2 v. The finding of study indicated that widespread and significant changes has occurred in study area during two decades in which remarkable increase occur in built up and vegetation land area, on the other hand reduction was observed in water body, barren and agriculture land area from year 1999 to 2018. During the whole study period, major land shifting was observed in agriculture to vegetation and vegetation to barren. The transformation in land cover use may pose severe risk to watershed resources. Therefore, proper management, effective conservation plans and strategies are necessary to designed for the protection of this natural resource.
