High Breakthrough Pressure in Hydrogels Enabled Ultrastable Treatment of Hypersaline Wastewaters.

Surface effects of low-surface-tension contaminants accumulating at the evaporation surface easily induce wetting in membrane distillation, especially in hypersaline scenarios. Herein, we propose a novel strategy to eliminate the surface effect and redistribute contaminants at the evaporation interface simply by incorporating a layer of hydrogel. The as-fabricated composite membrane exhibits remarkable stability, even when exposed to solution with salt concentration of 5 M and surfactant concentration of 8 mM. Breakthrough pressure of the membrane reaches 20 bar in the presence of surfactants, surpassing commercial hydrophobic membranes by one to two magnitudes. Density functional theory and molecular dynamics simulations reveal the important role of the hydrogel-surfactant interaction in suppressing the surface effect. As a proof of concept, we demonstrate the membrane in stably processing synthetic wastewater containing 144 mg L-1 surfactants, 1 g L-1 mineral oils, and 192 g L-1 NaCl, showing its potential in addressing challenges of hypersaline water treatment.

Deep learning for survival analysis in breast cancer with whole slide image data.

MOTIVATION: Whole slide tissue images contain detailed data on the sub-cellular structure of cancer. Quantitative analyses of this data can lead to novel biomarkers for better cancer diagnosis and prognosis and can improve our understanding of cancer mechanisms. Such analyses are challenging to execute because of the sizes and complexity of whole slide image data and relatively limited volume of training data for machine learning methods. RESULTS: We propose and experimentally evaluate a multi-resolution deep learning method for breast cancer survival analysis. The proposed method integrates image data at multiple resolutions and tumor, lymphocyte and nuclear segmentation results from deep learning models. Our results show that this approach can significantly improve the deep learning model performance compared to using only the original image data. The proposed approach achieves a c-index value of 0.706 compared to a c-index value of 0.551 from an approach that uses only color image data at the highest image resolution. Furthermore, when clinical features (sex, age and cancer stage) are combined with image data, the proposed approach achieves a c-index of 0.773.

The ethylene receptor regulates Typha angustifolia leaf aerenchyma morphogenesis and cell fate.

MAIN CONCLUSION: Ethylene receptor is crucial for PCD and aerenchyma formation in Typha angustifolia leaves. Not only does it receive and deliver the ethylene signal, but it probably can determine the cell fate during aerenchyma morphogenesis, which is due to the receptor expression quantity. Aquatic plant oxygen delivery relies on aerenchyma, which is formed by a programmed cell death (PCD) procedure. However, cells in the outer edge of the aerenchyma (palisade cells and septum cells) remain intact, and the mechanism is unclear. Here, we offer a hypothesis: cells that have a higher content of ethylene receptors do not undergo PCD. In this study, we investigated the leaf aerenchyma of the aquatic plant Typha angustifolia. Ethephon and pyrazinamide (PZA, an inhibitor of ACC oxidase) were used to confirm that ethylene is an essential hormone for PCD of leaf aerenchyma cells in T. angustifolia. That the ethylene receptor was an indispensable factor in this PCD was confirmed by 1-MCP (an inhibitor of the ethylene receptor) treatment. Although PCD can be avoided by blocking the ethylene receptor, excessive ethylene receptors also protect cells from PCD. TaETR1, TaETR2 and TaEIN4 in the T. angustifolia leaf were detected by immunofluorescence (IF) using polyclonal antibodies. The result showed that the content of ethylene receptors in PCD-unsusceptible cells was 4-14 times higher than that one in PCD-susceptible cells, suggesting that PCD-susceptible cells undergo the PCD programme, while PCD-unsusceptible cells do not due to the content difference in the ethylene receptor in different cells. A higher level of ethylene receptor content makes the cells insensitive to ethylene, thereby avoiding cell death and degradation.

The association of semaphorin 5A with lymph node metastasis and adverse prognosis in cervical cancer.

BACKGROUND: Semaphorin 5A has been linked to tumor growth, invasion, and metastasis in pancreatic cancer. However, the role of semaphorin 5A in cervical cancer is not known. Our aim is to investigate the prognostic value of semaphorin 5A and its potential role in lymphangiogenesis and invasion in cervical cancer. METHODS: In this study, pathological features and clinical data of 232 cervical cancer patients were retrospectively reviewed. Semaphorin 5A protein and mRNA expression was detected by immunohistochemistry and quantitative real-time reverse transcription-polymerase chain reaction, respectively. In vitro, we determined the role and mechanistic pathways of semaphorin 5A in tumor progression in cervical carcinoma cell lines. RESULTS: Semaphorin 5A expression was significantly higher in stage IIb tumors than in stage Ia, Ib, and IIa tumors. High semaphorin 5A expression was significantly associated with pelvic lymph node metastasis, lymphovascular permeation, and poor survival. Semaphorin 5A induced lymphangiogenesis through a plexin-B/Met/vascular endothelial growth factor-C pathway. Semaphorin 5A also increased cervical cancer cell invasion by stimulating the expression and activity of matrix metalloproteinase-2 and matrix metalloproteinase-9 via PI3K/AKT and plexin-B3. CONCLUSION: Our findings indicate that semaphorin 5A may represent a poor prognostic biomarker and anti-metastasis therapeutic target in cervical cancer.

Fimbrins 4 and 5 Act Synergistically During Polarized Pollen Tube Growth to Ensure Fertility in Arabidopsis.

The germination and polar growth of pollen are prerequisite for double fertilization in plants. The actin cytoskeleton and its binding proteins play pivotal roles in pollen germination and pollen tube growth. Two homologs of the actin-bundling protein fimbrin, AtFIM4 and AtFIM5, are highly expressed in pollen in Arabidopsis and can form distinct actin architectures in vitro, but how they co-operatively regulate pollen germination and pollen tube growth in vivo is largely unknown. In this study, we explored their functions during pollen germination and polar growth. Histochemical analysis demonstrated that AtFIM4 was expressed only after pollen grain hydration and, in the early stage of pollen tube growth, the expression level of AtFIM4 was low, indicating that it functions mainly during polarized tube growth, whereas AtFIM5 had high expression levels in both pollen grains and pollen tubes. Atfim4/atfim5 double mutant plants had fertility defects including reduced silique length and seed number, which were caused by severe defects in pollen germination and pollen tube growth. When the atfim4/atfim5 double mutant was complemented with the AtFIM5 protein, the polar growth of pollen tubes was fully rescued; however, AtFIM4 could only partially restore these defects. Fluorescence labeling showed that loss of function of both AtFIM4 and AtFIM5 decreased the extent of actin filament bundling throughout pollen tubes. Collectively, our results revealed that AtFIM4 acts co-ordinately with AtFIM5 to organize and maintain normal actin architecture in pollen grains and pollen tubes to fulfill double fertilization in plants.

Carbohydrate metabolism and gene regulation during anther development in an androdioecious tree, Tapiscia sinensis.

BACKGROUND AND AIMS: Tapiscia sinensis (Tapisciaceae) is a functional androdioecious species with both male and hermaphroditic individuals, and fruit ripening overlaps with flowering in the hermaphroditic individuals. Pollen vitality was lower in the hermaphrodites than in the males. Anther development requires nutrients, and carbohydrates are the basic nutrients; abnormal carbohydrate metabolism will result in pollen abortion. The aim of this research was to gain insight into the relationship between carbohydrate metabolism and the weakening of the male function of hermaphroditic flowers in T. sinensis. METHODS: Observation of morphology and microscopic and sub-microscopic structures was carried out. Sugar measurements and quantitative real-time PCR analysis were performed for the genes related to sugar metabolism and transport in the development of anthers in both males and hermaphrodites. The expression pattern of Cell wall invertase 2 (CWI2) and Sucrose transporter 2 (ST2) was explored by in situ hybridization. KEY RESULTS: At the vacuolate microspore (VM) stage, polysaccharides accumulated in the connective tissue of the hermaphroditic anthers, and the levels of total soluble sugar, sucrose and starch in the hermaphroditic anthers were significantly lower than in the male anthers. Most of the hermaphroditic pollen grains were empty, with degradation of the cytoplasm, absence of an intine layer and defective exines. There was a significant differential expression between male and hermaphroditic flowers of several key genes that are involved in sugar metabolism, transport and intine development. CWI2 and ST2 were expressed in the tapetum and microspores. The expression of CWI2 was significantly lower in hermaphrodites than in the males. CONCLUSIONS: Fruit ripening overlaps with flowering, leading to a severe reproductive burden on the hermaphroditic individuals. The hermaphroditic flowers regulating carbohydrate metabolism and transport to affect resources are biased towards the female function to ensure reproduction, causing a deficiency in resources for the development of pollen; thus, the pollen viability is lower. This makes it easier for males to invade the hermaphroditic population and form a functional androdioecious breeding system.

Semaphorin 4D expression is associated with a poor clinical outcome in cervical cancer patients.

Lymphangiogenesis is thought to be essential for cancer progression, making it an important target in cancer therapy. Lymphangiogenic factors (VEGF-C and VEGF-D) are upregulated in various tumors/cancers, and play an important role in lymphangiogenesis and lymph node metastasis. Similarly, semaphorin 4D (Sema4D) is a potent inducer of angiogenesis, and its overexpression is associated with tumor progression and poor prognosis in a variety of malignancies. However, little is known regarding the functional relationship between Sema4D and VEGF-C/VEGF-D and in the mediation of lymphangiogenesis and lymph node metastasis and clinical outcome. The current study aimed to evaluate the effect of Sema4D expression on outcome in patients with cervical cancer, and to explore the molecular mechanism of Sema4D in tumor progression. We evaluated Sema4D expression, density of lymphatic vessels, and invasion of lymphatic vessels with immunohistochemical methods in 232 human cervical cancers with long-term follow-up. Sema4D expression was correlated with patho-clinical parameters and patients' outcome. A cervical cancer cell line was used to investigate the contribution of sema4D to tumor progression by studying the role of Sema4D in VEGF-C/-D and cell migration using reverse transcription-polymerase chain reaction and Western blotting. We observed that Sema4D expression was higher in metastatic cervical cancer than in nonmetastatic cervical cancer (P<0.001). CD34-positive or D2-40-positive lymphatic vessel density was significantly increased in cases with lymph node metastasis compared with those without lymph node metastasis. The increased Sema4D expression was associated with VEGF-C/-D, the presence of lymphatic invasion, the occurrence of lymph node metastasis, and FIGO stage. We also observed a novel association between Sema4D upregulation and poor prognosis in cervical cancer. In vitro, the Sema4D inhibitory antibody and Sema4D-shRNA suppressed VEGF-C and VEGF-D in the human cervical carcinoma cell lines HeLa, Siha, and Caski cells. Invasiveness assay demonstrated that Sema4D could augment the invasive potential of the tumor cells in the cervical cancer lines and induction of cellular invasiveness by Sema4D stimulation could be inhibited by knockdown of plexinB1 by siRNA. Further mechanistic investigations of tumor cell invasiveness showed that Sema4D could induce activation of GTPase Ras homolog gene family, member A (RhoA), MAPK and AKT. In addition, plexinB1 knockdown by siRNA could suppress the Sema4D signal transmitted to MAPK and Akt. Taken together, these results suggest that Sema4D autocrine within tumor cells contributes to enhanced invasion and tumor progression through increased motility of cervical cancer and VEGF-C/-D-mediated lymphangiogenesis. Sema4D might be useful as a molecular marker of poor prognosis in cervical cancer.

JAM-C promotes lymphangiogenesis and nodal metastasis in non-small cell lung cancer.

This study aims to investigate lymphatic metastasis-related genes in non-small cell lung carcinomas (NSCLC). NSCLC tissue was analyzed for expression of junctional adhesion molecule-C (JAM-C) protein. Our data revealed novel associations between JAM-C overexpression in primary tumors and lymphatic microvessel density (LMVD), lymph node metastasis, and poorer overall survival and recurrence-free survival. We used the highly metastatic human lung adenocarcinoma cell line Anip973 and its parental line AGZY83-a, which has a low metastatic capacity, in vivo and vitro. We found that JAM-C played an important role in different metastasis capacity of lymph node. JAM-C affected tumor growth, LNM, JAM-C, VEGF-C, vasculature, and ERK1/2 phosphorylation (p-ERK1/2). ß1 integrin was involved in lymph node metastasis. Moreover, JAM-C knockdown in highly metastatic Anip973 decreased cell migration in scratch-wound assays. The JAM-C knockdown in Anip973 cells and JAM-C cDNA in AGZY83-a cells regulated the vascular endothelial growth factor C (VEGF-C) expression. Immunofluorescence showed that blocked VEGF-C expression in JAM-C shRNA Anip973 cells were restored after JAM-C treatment. JAM-C-induced VEGF-C in JAM-C cDNA AGZY83-a cells was also effectively inhibited by treatment with an antibody specifically against JAM-C. Use of media from Anip973 cells, AGZY83-a, and A549cells lung cancer cells that overexpressed or downregulated JAM-C was demonstrated to affect activity of VEGF-C-induced ß1 integrin subunit or ERK activity in human dermal lymphatic endothelial cells (HDLEC) treated with VEGF-C or inhibitory antibody to JAM-C. Overall, these results indicate that JAM-C could mediate metastasis as it contributes to VEGF-C expression in cancer cells. JAM-C affects ß1and ERK activation in HDLEC, thus promoting lymphangiogenesis and nodal metastasis. Our findings indicate that JAM-C may be a therapeutic target for preventing and treating lymphatic metastases.

Identifying atheroprotective fruits and vegetables by Mendelian Randomization analysis.

Background: Fruits and vegetables (FVs) are widely believed to mitigate the risk of atherosclerosis (AS). However, the causal relationships between specific FVs and AS risk factors remain unclear. Methods: This study performed two-sample Mendelian Randomization (MR) analysis to infer the causality of the intake of 28 kinds of FVs with AS, as well as its risk factors including blood low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) and C-reactive protein (CRP). GWAS genetic data for these exposures and outcomes were extracted from the IEU open GWAS project. Heterogeneity was evaluated using both Inverse Variance Weighted (IVW) and MR-Egger methods. MR-Egger regression was specifically deployed to detect potential pleiotropy. Furthermore, a "leave-one-out" sensitivity analysis was conducted to determine the impact of each individual single nucleotide polymorphism (SNP) on the combined outcome. Results: The analysis confirms a causal relationship between total fruit consumption and reduced levels of LDL-C (OR = 0.911, p = 0.007) and CRP (OR = 0.868, p = 0.008). Similarly, total vegetable intake is also causally associated with a reduction in CRP levels (OR = 0.858, p = 0.018). Specifically, garlic intake exhibits the most significant causal relationship with reduced risk of AS (OR = 0.985, p = 0.036) and also causally associated with lower levels of LDL-C and TG. Berry (OR = 0.929, p = 0.010) and potato (OR = 0.957, p = 0.020) intake both display a significant causal negative association with TG levels, while peach/nectarine consumption is significantly associated with reduced CRP levels (OR = 0.913, p = 0.010). Conclusion: This is the first MR study that systemically examined the causality between commonly consumed FVs and AS. Our findings highlight the atheroprotective effects of various FVs, particularly garlic, on cardiovascular health and the importance of tailored nutritional recommendations to prevent AS.

A growth factor-reduced culture system for colorectal cancer organoids.

Although organoids derived from tumor tissues have been widely used in cancer research, it is a great challenge for cultured organoids to retain the characteristics of the original tumor tissues due to their heterogeneity. In this study, we explore organoid culture recipes to capture tumor features of colorectal cancers. We find that the activation of Wnt and EGF signaling and inhibition of BMP signaling are non-essential for the survival of most colorectal cancer organoids (CRCOs). We design a growth factor-reduced culture medium containing FGF10, A83-01 (TGF-ß type I receptor inhibitor), SB202190 (p38 MAPK inhibitor), gastrin, and nicotinamide. Using this medium, we can maintain tumor features in long-term CRCO cultivation, as evidenced by histopathology, genetic stability, tumorigenicity, and response of clinical treatments. Our findings offer a reliable and economical strategy for CRCO culture, facilitating the utilization of organoids in colorectal cancer research and treatment.

HER2 phosphorylation induced by TGF-ß promotes mammary morphogenesis and breast cancer progression.

Transforming growth factor ß (TGF-ß) and HER2 signaling collaborate to promote breast cancer progression. However, their molecular interplay is largely unclear. TGF-ß can activate mitogen-activated protein kinase (MAPK) and AKT, but the underlying mechanism is not fully understood. In this study, we report that TGF-ß enhances HER2 activation, leading to the activation of MAPK and AKT. This process depends on the TGF-ß type I receptor TßRI kinase activity. TßRI phosphorylates HER2 at Ser779, promoting Y1248 phosphorylation and HER2 activation. Mice with HER2 S779A mutation display impaired mammary morphogenesis, reduced ductal elongation, and branching. Furthermore, wild-type HER2, but not S779A mutant, promotes TGF-ß-induced epithelial-mesenchymal transition, cell migration, and lung metastasis of breast cells. Increased HER2 S779 phosphorylation is observed in human breast cancers and positively correlated with the activation of HER2, MAPK, and AKT. Our findings demonstrate the crucial role of TGF-ß-induced S779 phosphorylation in HER2 activation, mammary gland development, and the pro-oncogenic function of TGF-ß in breast cancer progression.

Mesenchymal Stem Cell Derived Exosomes Repair Uterine Injury by Targeting Transforming Growth Factor-ß Signaling.

Intrauterine adhesions (IUA) refer to adhesions within the uterine cavity and cervix caused by injuries from uterine surgery. They are a significant cause of female infertility. Exosomes derived from mesenchymal stem cells (MSCs) play an active role in the treatment of IUA. However, the mechanism by which they reduce fibrosis in the damaged endometrium remains unclear. In this paper, we demonstrate that exosomes derived from placental mesenchymal stem cells (PMSCs) can restore uterine functions and improve the fertility rate of injured animals. This is achieved by promoting cell proliferation, increasing endometrial thickness, and reversing fibrosis. Regarding the molecular mechanism behind these therapeutic effects, we identify three specific miRNAs, namely, miR-125b-5p, miR-30c-5p, and miR-23a-3p, enriched in PMSC-exosomes, as the key players in the treatment of IUA. Specifically, miR-125b-5p/miR-30c-5p and miR-23a-3p inhibit the expression of smad2 and smad3 by targeting their 3'-untranslated regions, resulting in the downregulation of the transforming growth factor-ß (TGF-ß)/smad signaling pathway and the reversal of fibrosis. Notably, the safety of PMSC-exosomes in intrauterine treatment was also been confirmed. In conclusion, we illustrate that exosomes derived from PMSCs possess the capability to repair endometrial damage and enhance fertility in injured animals by regulating the TGF-ß/smad pathway via miR-125b-5p, miR-30c-5p, and miR-23a-3p. This provides insights into the precision treatment of IUA through exosome-based cell-free therapy.

Token Sparsification for Faster Medical Image Segmentation.

Can we use sparse tokens for dense prediction, e.g., segmentation? Although token sparsification has been applied to Vision Transformers (ViT) to accelerate classification, it is still unknown how to perform segmentation from sparse tokens. To this end, we reformulate segmentation as a sparse encoding → token completion → dense decoding (SCD) pipeline. We first empirically show that naïvely applying existing approaches from classification token pruning and masked image modeling (MIM) leads to failure and inefficient training caused by inappropriate sampling algorithms and the low quality of the restored dense features. In this paper, we propose Soft-topK Token Pruning (STP) and Multi-layer Token Assembly (MTA) to address these problems. In sparse encoding, STP predicts token importance scores with a lightweight sub-network and samples the topK tokens. The intractable topK gradients are approximated through a continuous perturbed score distribution. In token completion, MTA restores a full token sequence by assembling both sparse output tokens and pruned multi-layer intermediate ones. The last dense decoding stage is compatible with existing segmentation decoders, e.g., UNETR. Experiments show SCD pipelines equipped with STP and MTA are much faster than baselines without token pruning in both training (up to 120% higher throughput) and inference (up to 60.6% higher throughput) while maintaining segmentation quality. Code is available here: https://github.com/cvlab-stonybrook/TokenSparse-for-MedSeg.

Programmable microfluidics for dynamic multiband camouflage.

Achieving multiband camouflage covering both visible and infrared regions is challenging due to the broad bandwidth and differentiated regulation demand in diverse regions. In this work, we propose a programmable microfluidic strategy that uses dye molecules in layered fluids to manipulate visible light- and infrared-semitransparent solvent to manipulate infrared light. With three primary fluid inputs, we achieve 64 chromaticity values and 8 emissivities from 0.42 to 0.90. In view of the wide tuning range, we demonstrate that the microfluidic film can dynamically change its surface reflectance to blend into varying backgrounds in both visible and infrared images. Moreover, we fabricate the microfluidic device in a textile form and demonstrate its ability to match exactly with the colors of natural leaves of different seasons in the full hyperspectrum range. Considering the broadband modulation and ease of operation, the programmable microfluidic strategy provides a feasible approach for smart optical surfaces in long-span optical spectra.

Transforming Growth Factor Beta Promotes Inflammation and Tumorigenesis in Smad4-Deficient Intestinal Epithelium in a YAP-Dependent Manner.

Transforming growth factor beta (TGF-ß), a multifunctional cytokine, plays critical roles in immune responses. However, the precise role of TGF-ß in colitis and colitis-associated cancer remains poorly defined. Here, it is demonstrated that TGF-ß promotes the colonic inflammation and related tumorigenesis in the absence of Smad family member 4 (Smad4). Smad4 loss in intestinal epithelium aggravates colitis and colitis-associated neoplasia induced by dextran sulfate sodium (DSS) and azoxymethane/dextran sulfate sodium (AOM/DSS), leading to over-activated immune responses and increased TGF-ß1 levels. In Smad4-deficient organoids, TGF-ß1 stimulates spheroid formation and impairs intestinal stem cell proliferation and lineage specification. YAP, whose expression is directly upregulated by TGF-ß1 after Smad4 deletion, mediates the effect of TGF-ß1 by interacting with Smad2/3. Attenuation of YAP/TAZ prevents TGF-ß1-induced spheroid formation in Smad4-/- organoids and alleviates colitis and colitis-associated cancer in Smad4-deficient mice. Collectively, these results highlight an integral role of the TGF-ß/Smad4 axis in restraining intestinal inflammation and tumorigenesis and suggest TGF-ß or YAP signaling as therapeutic targets for these gastrointestinal diseases intervention.

The cyclooxygenase-expressing mesenchyme resists intestinal epithelial injury by paracrine signaling.

Paracrine signals play pivotal roles in organ homeostasis. Mesenchymal stromal cells (MSCs) play a key role in regulating epithelium homeostasis in the intestine while their paracrine effects are poorly characterized. Here, we identified prostaglandin E2 (PGE2) secreted by cyclooxygenase (COX)-expressing MSCs as a vital factor to maintain the intestinal mucosal barrier. We found that MSCs-induced organoid swelling through paracrine effect in vitro, a process due to enhanced water adsorption and is mediated by the COX-PGE2-EP4 axis. To further explore the regulatory effect of this axis on the intestinal epithelial barrier in vivo, we established the conditional knockout mouse model to specifically delete COX in MSCs and found that PGE2 reduction downregulated the gene Muc2 and induced a gastric metaplasia-like phenotype. Moreover, PGE2 defects increased the susceptibility of intestinal epithelium to colitis. Our study uncovers the paracrine signaling of COX-expressing MSCs in intestinal mucosal barrier maintenance, providing a basis for understanding the role of mesenchymal cells in the pathophysiological function of the intestine.

Conversion of Harmful Fly Ash Residue to Zeolites: Innovative Processes Focusing on Maximum Activation, Extraction, and Utilization of Aluminosilicate.

Reuse of the solid residue from coal fly ash alumina extraction (FAAE) by acid leaching is problematic. Conversion of this solid residue into aluminum-rich zeolite (13X) and silicon-rich zeolite (ZSM-5) was investigated in this research. The FAAE residue was activated by alkali roasting with Na2CO3 powder (110% mass fraction) at 890 °C for 60 min. Silicon and aluminum were mainly present as two mineral phases, Na2SiO3 and NaAlSiO4, respectively, in the product obtained after roasting. The roasted product was dissolved in water (liquid/solid ratio of 2) after 20 min at 100 °C. The water-leaching liquor was investigated for total conversion to aluminosilicate zeolites without external aluminum or silicon addition. Hydrothermal synthesis of aluminum-rich zeolite 13X was successful after fine tuning of the conditions, although the filtrate had an unusually high SiO2/Al2O3 molar ratio. Production of 13X consumed a large amount of aluminum, which increased the Si/Al ratio to a level suitable for synthesis of ZSM-5. The synthesis of ZSM-5 from the mother liquor of 13X was proved feasible. The FAAE residue was transformed into high-value zeolite products by nearly 100%. Additionally, the tail liquid of this process, mainly containing Na2CO3, was completely recycled. This process could be used to realize high-efficiency and high-value utilization of similar aluminosilicate solid wastes.

The Interplay Between TGF-ß Signaling and Cell Metabolism.

The transforming growth factor-ß (TGF-ß) signaling plays a critical role in the development and tissue homeostasis in metazoans, and deregulation of TGF-ß signaling leads to many pathological conditions. Mounting evidence suggests that TGF-ß signaling can actively alter metabolism in diverse cell types. Furthermore, metabolic pathways, beyond simply regarded as biochemical reactions, are closely intertwined with signal transduction. Here, we discuss the role of TGF-ß in glucose, lipid, amino acid, redox and polyamine metabolism with an emphasis on how TGF-ß can act as a metabolic modulator and how metabolic changes can influence TGF-ß signaling. We also describe how interplay between TGF-ß signaling and cell metabolism regulates cellular homeostasis as well as the progression of multiple diseases, including cancer.

Role of noncoding RNA in the pathophysiology and treatment of intrauterine adhesion.

Intrauterine adhesion (IUA) is one of the most common diseases of the reproductive system in women. It is often accompanied by serious clinical problems that damage reproductive function, such as menstrual disorder, infertility, or recurrent abortion. The clinical effect of routine treatment is not ideal, and the postoperative recurrence rate is still very high. Therefore, exploring the pathological mechanism of IUA and finding new strategies for the effective prevention and treatment of IUA are needed. The main pathological mechanism of IUA is endometrial fibrosis and scar formation. Noncoding RNA (ncRNA) plays an important role in the fibrosis process, which is one of the latest research advances in the pathophysiology of IUA. Moreover, the exosomal miRNAs derived from mesenchymal stem cells can be used to improve IUA. This paper reviewed the role of ncRNAs in IUA pathogenesis, summarized the core pathways of endometrial fibrosis regulated by ncRNAs, and finally introduced the potential of ncRNAs as a therapeutic target.
