Isthmin: A multifunctional secretion protein.

Isthmin is a polypeptide secreted by adipocytes that was first detected in Xenopus gastrula embryos. Recent studies have focused on the biological functions of isthmin in growth and development, angiogenesis, and metabolism. Distinct spatiotemporal expression of isthmin-1 (ISM-1) was observed during growth and development. ISM-1 plays an important role in the occurrence and development of cancer by regulating cell proliferation, migration, angiogenesis, and immune microenvironments. Moreover, ISM-1, as a newly identified insulin-like adipokine, increases adipocyte glucose uptake and inhibits hepatic lipid synthesis. However, the biological function of ISM-1 remains largely unknown. In this review, we highlight the structure and physiological functions of isthmin and explore its application potential, contributing to a better understanding of its function and providing prevention and treatment strategies for various diseases.

Revascularization of superior mesenteric artery occlusion via the arc of Buhler: A case report and literature review.

BACKGROUND: To report revascularization of a superior mesenteric artery (SMA) ostial occlusion via the Arc of Buhler. CASE REPORT: A 62-year-old female presented with 2 months of recurrent abdominal distension and postprandial pain. Computed tomography angiography (CTA) revealed ostial occlusion of the SMA with distal perfusion via the Arc of Buhler (connecting the celiac trunk and SMA). Conventional endovascular techniques failed. A 0.014 guidewire was passed retrograde through the occlusion via the Arc of Buhler. The guidewire was captured from the femoral sheath and balloon angioplasty with stent placement was performed. The patient had complete symptom resolution post-procedure. CONCLUSIONS: Retrograde revascularization via the Arc of Buhler is an effective method for treating the initial segment occlusion of the SMA.

Post-processing by a slave computer, the collected pulse wave data is wirelessly transmitted to a smartphone. The real-time pulse waveform, pulse rate, and blood oxygen levels are displayed on an application. Following relevant tests and verifications, the system can accurately detect pulse wave signals, meet the requirements for wearable technology, and possesses significant market application potential.

A New Target Detection Method of Ferrography Wear Particle Images Based on ECAM-YOLOv5-BiFPN Network.

For mechanical equipment, the wear particle in the lubrication system during equipment operation can reflect the lubrication condition, wear mechanism, and severity of wear between equipment friction pairs. To solve the problems of false detection and missed detection of small, dense, and overlapping wear particles in the current ferrography wear particle detection model in a complex oil background environment, a new ferrography wear particle detection network, EYBNet, is proposed. Firstly, the MSRCR algorithm is used to enhance the contrast of wear particle images and reduce the interference of complex lubricant backgrounds. Secondly, under the framework of YOLOv5s, the accuracy of network detection is improved by introducing DWConv and the accuracy of the entire network is improved by optimizing the loss function of the detection network. Then, by adding an ECAM to the backbone network of YOLOv5s, the saliency of wear particles in the images is enhanced, and the feature expression ability of wear particles in the detection network is enhanced. Finally, the path aggregation network structure in YOLOv5s is replaced with a weighted BiFPN structure to achieve efficient bidirectional cross-scale connections and weighted feature fusion. The experimental results show that the average accuracy is increased by 4.46%, up to 91.3%, compared with YOLOv5s, and the detection speed is 50.5FPS.

SIRT1 Mediates H2S-Ameliorated Diabetes-Associated Cognitive Dysfunction in Rats: Possible Involvement of Inhibiting Hippocampal Endoplasmic Reticulum Stress and Synaptic Dysfunction.

Diabetes-associated cognitive dysfunction (DACD) characterized by hippocampal injury increases the risk of major cerebrovascular events and death. Endoplasmic reticulum (ER) stress and synaptic dysfunction play vital roles in the pathological process. At present, no specific treatment exists for the prevention and/or the therapy of DACD. We have recently reported that hydrogen sulfide (H2S) exhibits therapeutic potential for DACD, but the underlying mechanism has not been fully elucidated. Silent information regulator 1 (SIRT1) has been shown to play a role in regulating the progression of diabetes and is also indispensable for memory formation and cognitive performance. Hence, the present study was performed to explore whether SIRT1 mediates the protective effect of H2S on streptozotocin (STZ)-induced cognitive deficits, an in vivo rat model of DACD, via inhibiting hippocampal ER stress and synaptic dysfunction. The results showed that administration of NaHS (an exogenous H2S donor) increased the expression of SIRT1 in the hippocampus of STZ-induced diabetic rats. Then, results proved that sirtinol, a special blocker of SIRT1, abrogated the inhibition of NaHS on STZ-induced cognitive deficits, as appraised by Morris water maze test, Y-maze test, and Novel object recognition behavioral test. In addition, administration of NaHS eliminated STZ-induced ER stress as evidenced by the decreases in the expressions of ER stress-related proteins including glucose-regulated protein 78, C/EBP homologous protein, and cleaved caspase-12 in the hippocampus, while these effects of NaHS were also reverted by sirtinol. Furthermore, the NaHS-induced up-regulation of hippocampal synapse-related protein (synapsin-1, SYN1) expression in STZ-induced diabetic rats was also abolished by sirtinol. Taken together, these results demonstrated that SIRT1 mediates the protection of H2S against cognitive dysfunction in STZ-diabetic rats partly via inhibiting hippocampal ER stress and synaptic dysfunction.

Formaldehyde induces ferritinophagy to damage hippocampal neuronal cells.

Formaldehyde (FA) causes neurotoxicity and contributes to the occurrence of neurodegenerative diseases. However, the mechanism of FA-induced neurotoxicity has not been fully elucidated. Ferritinophagy, an autophagy process of ferritin mediated by the nuclear receptor coactivator 4 (NCOA4), is a potential mechanism of neurotoxicity. In this study, we explored whether ferritinophagy is associated with the neurotoxicity of FA. Our results showed that FA (50, 100, 200 µM; 24 h) exposure upregulated ferritinophagy in the mouse hippocampal neuronal HT22 cells, which was evidenced by the upregulated autophagic flux, the increased colocalizations of NCOA4 with ferritin heavy chain (FTH1) and NCOA4 with microtubule-associated protein 1 light chain-3B (LC3B), the augmented expression of NCOA4, and the reduced content of FTH1. We also found that FA (0.1, 1, and 10 µmol, i.c.v., 7d) administration boosted ferritinophagy in the hippocampus of Sprague-Dawley (SD) rats, which was demonstrated by the accumulated autophagosomes, the increased expressions of LC3II/I and NCOA4, and the decreased contents of p62 and FTH1 in the hippocampus. Further, we confirmed that inhibition of ferritinophagy by silencing the expression of NCOA4 decreased FA-induced toxic damage in HT22 cells. These results indicated that FA induces neurotoxicity by promoting ferritinophagy. Our findings suggest a potential mechanism insight into the FA-induced neurotoxicity, which in turn provides a new thought for the treatment of FA-related neurodegenerative diseases.

Detecting the Mechanism behind the Transition from Fixed Two-Dimensional Patterned Sika Deer (Cervus nippon) Dermal Papilla Cells to Three-Dimensional Pattern.

The hair follicle dermal papilla is critical for hair generation and de novo regeneration. When cultured in vitro, dermal papilla cells from different species demonstrate two distinguishable growth patterns under the conventional culture condition: a self-aggregative three dimensional spheroidal (3D) cell pattern and a two dimensional (2D) monolayer cell pattern, correlating with different hair inducing properties. Whether the loss of self-aggregative behavior relates to species-specific differences or the improper culture condition remains unclear. Can the fixed 2D patterned dermal papilla cells recover the self-aggregative behavior and 3D pattern also remains undetected. Here, we successfully constructed the two growth patterns using sika deer (Cervus nippon) dermal papilla cells and proved it was the culture condition that determined the dermal papilla growth pattern. The two growth patterns could transit mutually as the culture condition was exchanged. The fixed 2D patterned sika deer dermal papilla cells could recover the self-aggregative behavior and transit back to 3D pattern, accompanied by the restoration of hair inducing capability when the culture condition was changed. In addition, the global gene expressions during the transition from 2D pattern to 3D pattern were compared to detect the potential regulating genes and pathways involved in the recovery of 3D pattern and hair inducing capability.

BDNF-TrkB pathway mediates antidepressant-like roles of H2 S in diabetic rats via promoting hippocampal autophagy.

Hydrogen sulfide (H2 S) plays antidepressant-like roles in diabetic rats. However, the underlying mechanisms remain unclear. Brain-derived neurotropic factor (BDNF), a neurotrophic factor, plays important regulatory roles in depression by its high-affinity tropomysin-related kinase B (TrkB) receptor. Autophagy also is implicated in modulation of depression. Previous work confirmed the modulatory roles of H2 S in BDNF protein expression and autophagy. Thus, in this study, we explored whether the BDNF-TrkB pathway mediates the antidepressant-like effects of H2 S in diabetic rats and whether this process is achieved via promoting hippocampal autophagy. We demonstrated that H2 S upregulated the expressions of BDNF and p-TrkB proteins in the hippocampus of streptozotocin (STZ)-induced diabetic rats. K252a (an inhibitor of BDNF-TrkB pathway) reversed the antidepressant-like roles of H2 S, as evidenced by the tail suspension, forced swimming, novelty suppressed feeding, and elevated plus-maze tests. Furthermore, K252a abolished H2 S-promoted hippocampal autophagy in diabetic rats, as evidenced by a decrease in the number of autolysosome, downregulation of Beclin-1 (a regulator of autophagy in the early stage of the formation of autophagosomal membranes and its level is positively correlated with autophagic activity) expression, and upregulation of P62 (a substrate of autophagic degradation and its level is inversely correlated with autophagic activity) expression, in the hippocampus of rats co-treated with NaHS and STZ. Taken together, these data indicated that the BDNF-TrkB pathway mediates the antidepressant-like roles of H2 S in diabetic rats by enhancing hippocampal autophagy.

Identification of the JY-1 in sika deer and its effects on granulosa cells cultured in vitro.

The oocyte-specific protein JY-1 was reported as an important regulator of both function of ovarian granulosa cells and early embryogenesis in cattle. Here, we found that the transcripts of JY-1 were also present in sika deer granulosa cells (GCs) through in situ hybridization and qRT-PCR. The complete sika deer JY-1 coding sequence was identified, which had three exons separated by two introns. It was detected that JY-1 knockdown caused apoptosis and abnormal cell cycle progression in GCs of sika deer cultured in vitro. Taken together, these data suggest that JY-1 is involved in the regulation of proliferation in sika deer ovarian GCs.

Transcriptome Changes in the Mink Uterus during Blastocyst Dormancy and Reactivation.

Embryo implantation in the mink follows the pattern of many carnivores, in that preimplantation embryo diapause occurs in every gestation. Details of the gene expression and regulatory networks that terminate embryo diapause remain poorly understood. Illumina RNA-Seq was used to analyze global gene expression changes in the mink uterus during embryo diapause and activation leading to implantation. More than 50 million high quality reads were generated, and assembled into 170,984 unigenes. A total of 1684 differential expressed genes (DEGs) in uteri with blastocysts in diapause were compared to the activated embryo group (p < 0.05). Among these transcripts, 1527 were annotated as known genes, including 963 up-regulated and 564 down-regulated genes. The gene ontology terms for the observed DEGs, included cellular communication, phosphatase activity, extracellular matrix and G-protein couple receptor activity. The KEGG pathways, including PI3K-Akt signaling pathway, focal adhesion and extracellular matrix (ECM)-receptor interactions were the most enriched. A protein-protein interaction (PPI) network was constructed, and hub nodes such as VEGFA, EGF, AKT, IGF1, PIK3C and CCND1 with high degrees of connectivity represent gene clusters expected to play an important role in embryo activation. These results provide novel information for understanding the molecular mechanisms of maternal regulation of embryo activation in mink.

[Present situation and analysis of deer industry standardization at home and abroad].

Deer is valuable all over the body,which is rich in nutritional value and medicinal value. Deer breeding and processing are very advanced in North America and New Zealand where many related standards have been published. The development of Chinese deer industry lack standard and normal management,neither standards' number nor coverage area formed complete frame structure. The international standards like Panax ginseng and P. notoginseng were more lacked. This paper makes a classification statistics on standardization organizations at home and abroad,foreign standards,Chinese national standards,industry standards,local standards and enterprise standards. The classes,contents,ages,implementation and promotion and demonstration area construction of standards were compared and analyzed. We found Chinese deer industry standards were deficient in coverage,uniformity,innovation,repeatability and support. And we give advises for the construction of industry quality standard system,organizational mobility and ideology of consumers,hoping to boost the standard construction and promote international competitiveness of Chinese deer industry.

Histone deacetylase inhibitor stimulates E2 and P4 secretion in sika deer ovarian granulosa cells at a moderate dose.

The histone deacetylase inhibitor (HDACi) and tumor suppressor play an important role in genome reorganization and epigenetic regulation. In this study, granulosa cells (GCs) isolated from sika deer ovaries were cultured and treated with different concentrations of trichostatin A (TSA) for 48 h. It was found that TSA inhibited GCs proliferation and induced GCs apoptosis by upregulating expression of BAX, meanwhile, downregulating expression of GLUT3, GLUT8, BCL-XL. In addition, TSA caused cell cycle arrest at the G1 and G2/M phase accompanied by reducing expression of Cyclin D2 and CDK4. TSA pretreatment increased DNMT3a, DNMT1, HDAC1, and HAT1 expression, and attenuated them when TAS higher than 50 nM. The protein levels of H3K9ac and H4K8ac in GCs were increased at 48 h after TSA treatment. TSA stimulated the secretion of estradiol and progesterone at a moderate dose. Our data suggest that TSA is important as a regulator of steroid hormone synthesis in granulosa cells during follicular development in the sika deer ovary.

Hydrogen Sulfide Ameliorates Homocysteine-Induced Cognitive Dysfunction by Inhibition of Reactive Aldehydes Involving Upregulation of ALDH2.

Background: Homocysteine, a risk factor for Alzheimer's disease, induces cognitive dysfunction. Reactive aldehydes play an important role in cognitive dysfunction. Aldehyde-dehydrogenase 2 detoxifies reactive aldehydes. Hydrogen sulfide, a novel neuromodulator, has neuroprotective effects and regulates learning and memory. Our previous work confirmed that the disturbance of hydrogen sulfide synthesis is invovled in homocysteine-induced defects in learning and memory. Therefore, the present work was to explore whether hydrogen sulfide ameliorates homocysteine-generated cognitive dysfunction and to investigate whether its underlying mechanism is related to attenuating accumulation of reactive aldehydes by upregulation of aldehyde-dehydrogenase 2. Methods: The cognitive function of rats was assessed by the Morris water maze test and the novel object recognition test. The levels of malondialdehyde, 4-hydroxynonenal, and glutathione as well as the activity of aldehyde-dehydrogenase 2 were determined by enzyme linked immunosorbent assay; the expression of aldehyde-dehydrogenase 2 was detected by western blot. Results: The behavior experiments, Morris water maze test and novel objects recognition test, showed that homocysteine induced deficiency in learning and memory in rats, and this deficiency was reversed by treatment of NaHS (a donor of hydrogen sulfide). We demonstrated that NaHS inhibited homocysteine-induced increases in generations of MDA and 4-HNE in the hippocampus of rats and that hydrogen sulfide reversed homocysteine-induced decreases in the level of glutathione as well as the activity and expression of aldehyde-dehydrogenase 2 in the hippocampus of rats. Conclusion: Hydrogen sulfide ameliorates homocysteine-induced impairment in cognitive function by decreasing accumulation of reactive aldehydes as a result of upregulations of glutathione and aldehyde-dehydrogenase 2.

Antidepressant-like and anxiolytic-like effects of hydrogen sulfide in streptozotocin-induced diabetic rats through inhibition of hippocampal oxidative stress.

Depression is highly prevalent in individuals with diabetes, and depressive symptoms are less responsive to current antidepressant therapies. Oxidative stress plays a major role both in the pathogenesis of diabetes and in major depression and anxiety disorders. Hydrogen sulfide (H2S), the third gaseous mediator, is a novel signaling molecule in the brain that has both antioxidative activity and antidepressant-like and anxiolytic-like effects. We hypothesized that H2S could produce antidepressant-like and anxiolytic-like effects in diabetic patients through its antioxidative effect. To test this hypothesis, we generated streptozotocin (STZ)-induced diabetic rats. We found that H2S alleviated depressive-like behaviors of STZ-induced diabetic rats in the forced swimming and tail suspension tests and reduced their anxiety-like behaviors in the elevated plus maze test. We also found that H2S significantly reduced levels of malondialdehyde and 4-hydroxynonenal and elevated levels of superoxide dismutase and reduced glutathione in the hippocampus of STZ-induced diabetic rats. The results provide evidence for antidepressant-like and anxiolytic-like effects of H2S in STZ-induced diabetic rats and suggest that the therapeutic effects may result from inhibition of hippocampal oxidative stress. These findings suggest that elevating H2S signaling is a potential target for treatment of depressive and anxiety disorders related to diabetes.

Hydrogen sulfide inhibits homocysteine-induced endoplasmic reticulum stress and neuronal apoptosis in rat hippocampus via upregulation of the BDNF-TrkB pathway.

AIM: Homocysteine (Hcy) can elicit neuronal cell death, and hyperhomocysteinemia is a strong independent risk factor for Alzheimer's disease. The aim of this study was to examine the effects of hydrogen sulfide (H2S) on Hcy-induced endoplasmic reticulum (ER) stress and neuronal apoptosis in rat hippocampus. METHODS: Adult male SD rats were intracerebroventricularly (icv) injected with Hcy (0.6 µmol/d) for 7 d. Before Hcy injection, the rats were treated with NaHS (30 or 100 µmol·kg(-1)·d(-1), ip) and/or k252a (1 µg/d, icv) for 2 d. The apoptotic neurons were detected in hippocampal coronal slices with TUNEL staining. The expression of glucose regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), cleaved caspase-12, and BDNF in the hippocampus were examined using Western blotting assays. The generation of H2S in the hippocampus was measured with the NNDPD method. RESULTS: Hcy markedly inhibited the production of endogenous H2S and increased apoptotic neurons in the hippocampus. Furthermore, Hcy induced ER stress responses in the hippocampus, as indicated by the upregulation of GRP78, CHOP, and cleaved caspase-12. Treatment with the H2S donor NaHS increased the endogenous H2S production and BDNF expression in a dose-dependent manner, and significantly reduced Hcy-induced neuronal apoptosis and ER stress responses in the hippocampus. Treatment with k252a, a specific inhibitor of TrkB (the receptor of BDNF), abolished the protective effects of NaHS against Hcy-induced ER stress in the hippocampus. CONCLUSION: H2S attenuates ER stress and neuronal apoptosis in the hippocampus of Hcy-treated rats via upregulating the BDNF-TrkB pathway.

Postoperative Pyoderma Gangrenosum in a Patient Presenting with Acute Peripheral Artery Disease Secondary to Antiphospholipid Syndrome: A Case Report.

Pyoderma gangrenosum (PG) is a rare autoinflammatory neutrophilic dermatosis clinically characterized by painful nodules, red papules or plaques that rapidly erode into ulcers. We report a 53-year-old febrile male patient with acute peripheral arterial disease who underwent transtibial amputation after failed thrombolysis. Five days after amputation, an ulcer developed around the cannulation site of the right internal jugular vein that was indicative of pathergy. The patient's fever did not improve after surgery, and purpuric discoloration and punctate ulcers of the skin near the amputation site became apparent, leading to re-debridement. Finally, consultation with a dermatologist raised the possibility of postoperative PG, and additional laboratory tests revealed positive anticardiolipin autoantibodies consistent with antiphospholipid syndrome. The patient was treated with intravenous glucocorticosteroids and antibiotics, and the amputation wound and cannulation site ulcer were found to have healed at the 2-month follow-up. The current report raises the need for vascular surgeons to be aware of this uncommon etiology of arterial thrombosis, and the postoperative appearance of dermatosis and pathergy should alert for PG.

Clinical characteristics of lower extremity deep vein thrombosis in young vs. middle-aged adults: a single-center retrospective study.

Background: The incidence of deep vein thrombosis (DVT) in the lower extremities is increasing in the younger population. However, there are fewer reported comparisons in the literature for lower extremity DVT. Methods: Patients aged <40 years admitted with lower-extremity DVT between January 2018 and December 2023 were retrospectively analyzed and followed up for 1 year. Results: A total of 61 patients were included in the study and divided into two groups: 33 patients over 30 years of age (middle-aged group) and 28 patients under 30 years of age (young group). A significant gender difference was observed, with a higher proportion of males in the young group compared to the middle-aged group (P < 0.001). Five patients in the young group were treated with anticoagulation alone, whereas all patients in the middle-aged group underwent endovascular therapy. A higher prevalence of inferior vena cava thrombosis in the young group compared to the middle-aged group (60.71% vs. 33.3%, P = 0.032). The proportion of iliac vein stenosis was significantly higher in the middle-aged groups than in the young group (P = 0.002). There was no statistically significant difference in venous function scores (Villalta and rVCSS) between the two groups during both the preoperative period and the postoperative follow-up (P > 0.05). The incidence of lower-extremity DVT post-thrombotic syndrome and thrombus recurrence was higher in the young group than in the middle-aged group at 1 year postoperatively (PTS: 78.57% vs. 33.3%, P < 0.001, and thrombus recurrence: 28.57% vs. 9.09%, P < 0.05). Univariate and multivariate analyses revealed that inferior vena cava thrombosis was an independent risk factor for severe DVT post-thrombotic syndrome and recurrent DVT (P < 0.05), whereas gender was an independent risk factor for recurrent DVT (P < 0.05). Conclusions: This study suggests differences in the clinical characteristics and prognosis of lower-extremity DVT.

Comparison of one-year outcomes and quality of life between endovenous microwave ablation and high ligation and stripping of the great saphenous vein.

INTRODUCTION: The objective of this study is to evaluate and compare the effectiveness of endovenous microwave ablation (EMA) and high ligation and strippingn (HLS) of the great saphenous vein (GSV) in the treatment of varicose veins. METHODS: We included 182 patients in each EMA and HLS groups. Follow-up outcomes included AVVQ, VCSS, chronic venous insufficiency questionnaire-14 (CIVIQ14) score, clinical recurrence rate of varicose vein treatment, and patient satisfaction during the 1-year follow-up period. RESULTS: At the 1-year follow-up, no significant difference was found in the clinical recurrence rate of varicose veins between the EMA and HLS groups (p = .75). The duration of the operation and the length of hospital stay for patients in the EMA group was shorter than that for the HLS group (p < .01). The Aberdeen Varicose Vein Questionnaire (AVVQ), Venous Clinical Severity Score (VCSS) score, and ecchymosis were lower for patients who underwent EMA surgery (p < .01). CONCLUSION: Our research results confirm that EMA improves patients' quality of life with lower limb varicose veins, with EMA showing higher patient satisfaction.

Atlas of Cell Repertoire Within Neointimal Lesions Is Metabolically Altered in Hypertensive Rats.

BACKGROUND: High blood pressure has been suggested to accelerate vascular injury-induced neointimal formation and progression. However, little is known about the intricate relationships between vascular injury and hypertension in the context of arterial remodeling. METHODS: Single-cell RNA-sequencing analysis was used to depict the cell atlas of carotid arteries of Wistar Kyoto rats and spontaneously hypertensive rats with or without balloon injury. RESULTS: We found that hypertension significantly aggravated balloon injury-induced arterial stenosis. A total of 36 202 cells from carotid arteries with or without balloon injury were included in single-cell RNA-sequencing analysis. Cell composition analysis showed that vascular injury and hypertension independently induced distinct aortic cell phenotypic alterations including immune cells, endothelial cells (ECs), and smooth muscle cells. Specifically, our data showed that injury and hypertension-induced specific EC phenotypic alterations, and revealed a transition from functional ECs to hypermetabolic, and eventually dysfunctional ECs in hypertensive rats upon balloon injury. Importantly, our data also showed that vascular injury and hypertension-induced different smooth muscle cell phenotypic alterations, characterized by deferential expression of synthetic signatures. Interestingly, pathway analysis showed that dysregulated metabolic pathways were a common feature in monocytes/macrophages, ECs, and smooth muscle cells in response to injury and hypertension. Functionally, we demonstrate that inhibition of mitochondrial respiration significantly ameliorated injury-induced neointimal formation in spontaneously hypertensive rats. CONCLUSIONS: This study provides the cell landscape changes of the main aortic cell phenotypic alterations in response to injury and hypertension. Our findings suggest that targeting cellular mitochondrial respiration could be a novel therapeutic for patients with hypertension undergoing vascular angioplasty.
