bowringi females. Lipin silencing blocked ovarian development and strongly suppressed transcription of vitellogenin and vitellogenin receptor genes. In addition, the reduction in Lipin expression led to a rapid increase in lipid storage in the fat body and also promoted the expression of genes related to lipid synthesis and stress tolerance. Overall, these results suggest that a Lipin-mediated lipolytic system is essential for maintaining lipid homeostasis during reproduction in C. bowringi. The findings of this study provide a foundation for future studies on the relationship between lipid metabolism and reproduction in invertebrates.
Accurate prosthesis placement in arthroplasty is an important factor in the long-term success of these interventions. Many types of guidance technology have been described to date often suffering from high costs, complex theatre integration, time inefficiency, and problems with day-to-day usability. We present a novel, intraoperative robotics platform, capable of rapid, real-time manufacture of low-cost patient-specific guides whilst overcoming many of the issues with existing approaches.

A prototype robotics platform was assessed in a 24-specimen cadaveric trial during sequential simulated shoulder arthroplasty procedures. The platform consisted of a tableside robot with sterile drapes and sterile disposable components. The robot itself comprised a 3D optical scanner, a three-axis sterile robotic drill and a two-axis receptacle into which the disposable consumables were inserted. The consumable comprised of a region of rapidly setting moldable material and a clip allowing it to be reversibly attached to to improve accuracy in other areas of arthroplasty.Increasing evidence confirms that sleep deprivation (SD), which induces hippocampal neuroinflammation, is a risk factor for depression. Hydrogen sulfide (H2S) is a novel neuromodulator that plays antidepressant-like role. Silent mating type information regulation 2 homolog 1 (Sirt1) is well-characterized as a regulator of mood disorder. Furthermore, we have previously reported that H2S upregulates Sirt1 expression in the hippocampus of SD-exposed rats. Here, we explored whether H2S ameliorates depression- and anxiety-like behaviors as well as hippocampal neuroinflammatory in SD-exposed rats and whether Sirt1 mediates these protective roles of H2S. In the present work, we showed that NaHS (a donor of H2S) significantly alleviated depression- and anxiety-like behaviors in the SD-exposed rats tested by novelty-suppressed feeding test (NST), forced swim test (FST), tail suspension test (TST), and elevated plus maze test (EPMT) and that NaHS attenuates neuroinflammatory in the hippocampus of SD-exposed rats, as evidenced by reducing the levels of pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α) and chemokine CCL2, as well as increasing the levels of anti-inflammatory cytokines (IL-4 and IL-10) in the hippocampus. However, Sirt1 inhibitor reversed the protective effects of H2S against SD-induced depression- and anxiety-like behaviors as well as hippocampal neuroinflammatory. In conclusion, H2S antagonizes SD-induced depression- and anxiety-like behaviors and neuroinflammation, which is required hippocampal Sirt1. These findings suggested that H2S is a novel approach to prevent SD-induced depression and anxiety.Environmental enrichment (EE) has been proven to reduce drug seeking and the development of addiction-related behaviors in rodent models, but the effects of EE on natural reward acquisition in the form of sweet beverages are poorly understood. Accumulating evidence shows that the intake of sugar, the main ingredient of sweet beverages, alters the dopaminergic system, leading to addiction-related physiological and molecular changes. Sugar in sweet beverages has been replaced with natural sweeteners, such as stevia extract, which has greater sweetener potential but no energy content. Our research group found that sucralose consumption increased the expression of ΔFosB in reward-related nuclei, suggesting activation of the dopaminergic system. The present study assessed the effects of EE on stevia consumption and the expression of ΔFosB in the nucleus accumbens, caudate putamen, and prefrontal cortex. Sixteen male Wistar rats, 21 days old, were randomly assigned to an EE group (n = 8) or standard environment (SE) group (n = 8) and reared for 30 days. On postnatal day 52 (PND52), the brains of four animals in each housing condition were extracted to determine basal ΔFosB levels. Stevia consumption with intermittent access and ΔFosB immunoreactivity were measured for 21 days in the remainder of the rats. Compared with SE animals, EE animals exhibited a reduction of stevia consumption and alterations of ΔFosB immunoreactivity in the reward system. These results indicate that EE reduces stevia consumption and the stevia-induced ΔFosB expression, suggesting addiction-related changes in dopaminergic nuclei, which may be interpreted as a neuroprotective effect.
Traumatic Brain Injury (TBI) is widely acknowledged as a significant risk factor for death and disability. Our goal in this experiment was to see if Auraptene (AUR) could help rats recover from TBI-induced disability by measuring of oxidative stress parameters.

Adult male Wistar rats were randomly assigned to one of six groups sham, TBI, Vehicle (DMSO), TBI+AUR (4 mg/kg), TBI +AUR (8 mg/kg), TBI +AUR (25 mg/kg). The animals were anesthetized. After that, diffuse TBI was done by Marmarou model in male rats. Then, the brain tissues were harvested. Some of oxidative stress parameters, and TNFα levels were evaluated.

TBI-induced brain damage was significantly inhibited by AUR (25 mg/kg), as evidenced by decreased Malondialdehyde (MDA) and Nitric Oxide (NO) levels, oxidative stress inhibition and reduced levels of pro-inflammatory cytokine tumor necrosis factor (TNF-α) in the brain.

This study showed that probably the AUR prevents complications of TBI through decreases in brain edema, modulating oxidative stress, and reductions in the levels of inflammatory cytokines.

To investigate whether dose planned to cardiac structures is associated with the risk of heart disease (HD) in breast cancer patients treated with radiotherapy, and whether this association is modified by presence of coronary artery calcification (CAC).

Radiotherapy planning CT scans and corresponding dose distribution maps of 5,561 patients were collected, 5300 patients remained after exclusion of ineligible patients and duplicates. AG14361 1,899 patients received their CT scan before 2011, allowing long follow-up. CAC was detected automatically. Using an artificial-intelligence-based method, cardiac structures (heart, cardiac chambers, large arteries, three main coronary arteries) were segmented. The planned radiation dose to each structure separately and to the whole heart were determined. Patients were assigned to a low-, medium-, or high-dose group based on the dose to the respective heart structure. Per patient, information on HD hospitalization and mortality was obtained. The association of planned radiatipatients with CAC.
Radiation exposure of cardiac structures is associated with increased risk of HD. Automatic segmentation of cardiac structures enables spatially localized dose estimation, which may aid in prevention of radiotherapy-induced cardiac damage. This may be especially valuable in breast cancer patients with CAC.Mitomycin treatment induces pulmonary toxicity, and alveolar epithelial cell senescence is crucial in the pathogenesis of the latter. However, the mechanism by which mitomycin induces alveolar epithelial cell senescence has yet to be elucidated. In this work, different doses (37.5-300 nM) of mitomycin induced the senescence of human alveolar type II-like epithelial cells and enhanced the phosphorylation of GSK3β (S9). The GSK3β (S9A) mutant reversed the senescence of mitomycin-treated alveolar epithelial cells. Pharmacological inhibition and gene deletion of Akt1, a kinase that regulates the phosphorylation of GSK3β (S9), suppressed mitomycin-induced alveolar epithelial cell senescence. The knockdown of p53, a downstream effector of GSK3β and an important regulator of cell senescence, repressed mitomycin-induced alveolar epithelial cell senescence. Treatment with baicalein weakened the phosphorylation of GSK3β (S9) and alleviated the senescence of alveolar epithelial cells brought about by mitomycin treatment. GSK3β (S9) phosphorylation appears to be the first signal involved in the mitomycin-induced senescence of alveolar epithelial cells and may present a potential target for attenuating mitomycin-induced pulmonary toxicity.SERPINB5 is a mammary serine protease inhibitor, which is involved in various cellular functions. The aberrant expression of SERPINB5 is reported in many cancers along with GBC but limited information is available about its role in genetic predisposition for GBC. We carried out case-control study in 206 cases and 219 controls. Promoter SNPs were genotyped by Sanger's sequencing. In-silico promoter analysis and luciferase reporter assay were done to elucidate the role of promoter variants in regulation of SERPINB5 expression. Out of four SNPs, three SERPINB5 promoter variants showed association with GBC in different models. The 'C' allele of variant rs17071138 was found to be significantly associated with GBC (p = 0.017). The 'T' allele of rs3744940 significantly increased the risk for GBC in dominant (p = 0.035) and additive models (p = 0.005). Also, rs3744941 'T' allele increased the risk for GBC by dominant (p = 0.042) as well as additive models (p = 0.016). In-silico promoter analysis and luciferase reporter assay revealed the probable regulatory role of the SERPINB5 promoter variant rs17071138 on the expression. Overall, our study reveals the genetic association of SERPINB5 promoter variants with GBC and possible role of rs17071138 in the regulation of expression.Soft tissue sarcomas (STSs) are highly aggressive malignant tumors that exhibit poor therapeutic outcomes. Hence, we aimed to track down a potential gene that can be used as a prognostic marker and therapeutic target for this malignancy. We integrated omics analysis of clinical data and in vitro studies and identified Ribonucleotide reductase subunit M2 (RRM2) as a potential oncogene associated with STS prognosis. We found RRM2 is highly expressed in STS cell lines and tissues. STS patients with increased RRM2 levels showed worse overall survival, disease-free survival, progression-free survival, and disease-specific survival. Further, overexpression of RRM2 in HT1080 cells induces proliferation, migration, invasion, and colony formation, whereas its silencing arrest the cell cycle at G0/G1 phase and induces apoptosis. Taken together, we established RRM2 to be positively associated with oncogenesis and prognosis of STS and therefore could be a promising prognostic marker and therapeutic target.The abnormal expression of integrin superfamily members commonly related to kinds of malignancies. However, the role of integrins in predicting the prognosis of cancers is still little known, especially for colorectal cancer that is one of the leading causes of cancer-related death. RNA-seq data and clinical features of colorectal adenocarcinoma (COAD) patients were derived from The Cancer Genome Atlas (TCGA), used to analyze the expression pattern and genomic alterations of integrin genes in the COAD cohort. Unsupervised hierarchical clustering divided COAD patients into two clusters (clusters 1 & 2), and we observed that patients in cluster 2 with high expressions of most integrin genes had worse clinical features and shorter overall survival (a median OS 67.25 months vs 99.93 months, p = 0.012), compared to those in cluster 1. Combined with univariate Cox regression analysis, Pearson Correlation Coefficients (PCC), and Principal Component Analysis (PCA), an integrin-related signature was established, including ITGA1, ITGA5, ITGA7, ITGA11, ITGAX, ITGAM, ITGB1, and ITGB5.
