Effects of a novel HDAC6-selective inhibitor's radiosensitization on cancer cells.

The radiation sensitivity of tumor cells is a critical determinant of their therapeutic response to radiotherapy. Histone deacetylase 6 (HDAC6), beyond its known role in modulating tubulin acetylation and influencing cell motility, is also involved in the DNA damage response, potentially enhancing tumor cell radiosensitivity. Targeted HDAC6 inhibitors have shown substantial promise in preclinical studies aimed at increasing radiosensitivity and inhibiting cellular migration. A new HDAC inhibitor, named OXHA, was designed by substituting the phenyl cap of SAHA with an N,5-diphenyloxazole-2-carboxamide group. The inhibitory activity of OXHA was evaluated via in vitro enzymatic assays. Its effects on tumor cell migration and radiosensitization potential were assessed using scratch wound healing assays, micronucleus formation, and clonogenic survival assays. Enzymatic assays confirmed OXHA's selective inhibition of HDAC6. Compared to SAHA, OXHA significantly increased α-tubulin acetylation while minimally impacting histone H3 acetylation, indicating a high selectivity for HDAC6. In combination with X-ray irradiation, OXHA markedly impaired wound healing in A549 and HepG2 cells, enhanced micronucleus formation, and reduced clonogenic survival across multiple tumor lines. OXHA exhibits potent and selective HDAC6 inhibition, effectively impeding tumor cell migration and enhancing radiosensitivity across multiple cell lines. These findings suggest that OXHA has strong potential as a therapeutic strategy to improve radiotherapy efficacy.

Turkish Astragalus Species: Botanical Aspects, Secondary Metabolites, and Biotransformation.

Astragalus is a widespread genus comprising approximately 3500 species, both annual and perennial, found across Asia, Europe, Africa, and the Americas. In Turkey, it is represented by 63 sections and 485 taxa with a high endemism ratio (51%). In traditional medicine, the roots of various Astragalus species represent very old and well-known drugs used for antiperspirant, diuretic, and tonic purposes, as well as for the treatment of nephritis, diabetes, leukemia, and uterine cancer. The genus Astragalus is the richest source of cycloartane-type compounds, which display a diverse range of bioactivities, such as wound healing, immunomodulatory, antitumor, hepatoprotective, antimutagenic, antiviral, and antiprotozoal activities. Moreover, cycloastragenol, the main sapogenol of many cycloartane-type glycosides found in the Astragalus genus, has gained attention as a potent telomerase activator over the past decade. The preparation of cycloastragenol derivatives could be significant in the near future due to their unique bioactivity. This review covers the botanical aspects of Astragalus L., as well as the phytochemical and biological activity studies conducted on Turkish Astragalus species, with a special focus on cycloartenols. It contains 36 articles reporting the phytochemistry of 29 Astragalus species and 111 new compounds, including 104 triterpene saponins. In addition to the phytochemical studies, this review summarizes the biotransformation studies on Astragalus cycloartanes via endophytic fungi isolated from the tissues of Astragalus species.

Hepatocellular senescence induces multi-organ senescence and dysfunction via TGFβ.

Cellular senescence is not only associated with ageing but also impacts physiological and pathological processes, such as embryonic development and wound healing. Factors secreted by senescent cells affect their microenvironment and can induce spreading of senescence locally. Acute severe liver disease is associated with hepatocyte senescence and frequently progresses to multi-organ failure. Why the latter occurs is poorly understood. Here we demonstrate senescence development in extrahepatic organs and associated organ dysfunction in response to liver senescence using liver injury models and genetic models of hepatocyte-specific senescence. In patients with severe acute liver failure, we show that the extent of hepatocellular senescence predicts disease outcome, the need for liver transplantation and the occurrence of extrahepatic organ failure. We identify the TGFβ pathway as a critical mediator of systemic spread of senescence and demonstrate that TGFβ inhibition in vivo blocks senescence transmission to other organs, preventing liver senescence induced renal dysfunction. Our results highlight the systemic consequences of organ-specific senescence, which, independent of ageing, contributes to multi-organ dysfunction.

The Infected Diabetic Foot: Does Negative Pressure Wound Therapy with Irrigation Reduce Bioburden and Improve Wound Healing?

The aim of this study was to compare the microbial loads of patients with diabetic foot infections treated with negative pressure wound therapy (NPWT) with and without irrigation with polyhexamethylene biguanide (NPWTi-P). This is a post hoc analysis of combined data of two randomized clinical trials. We evaluated people with diabetes treated with moderate and severe diabetic foot infections that required surgery. Tissue specimens were obtained after the initial surgery and following a second planned return to the operating room after 48-72 h of NPWT or NPWTi-P, prior to the second surgery. We used quantitative polymerase chain reaction (qPCR) to determine the total microbial loads (Log10 16S copies per gram of tissue). There was no difference in mean quantitative bacterial cultures among patients that received NPWT and NPWTi-P (before first surgery Log10: NPWT = 6.4 ± 1.8, NPWTi-P = 7.5 ± 1.7 vs before second surgery Log10: NPWT = 6.7 ± 1.8, NPWTi-P = 7.6 ± 1.9 p = .12). There was no difference in wound healing (59.5% vs 50.0%, p = .51) or time to heal (127 ± 109.3 vs 143 ± 95.9), p = .71). There were fewer re-infections in people that received traditional NPWT (28.6% vs 56.3%, p = .05). Level of Clinical Evidence: Level 1.

Growth hormone-releasing hormone and its analogues in health and disease.

Growth hormone-releasing hormone (GHRH) and its ability to stimulate the production and release of growth hormone from the pituitary were discovered more than four decades ago. Since then, this hormone has been studied extensively and research into its functions is still ongoing. GHRH has multifaceted roles beyond the originally identified functions that encompass a variety of direct extrapituitary effects. In this Review, we illustrate the different biological activities of GHRH, covering the effects of GHRH agonists and antagonists in physiological and pathological contexts, along with the underlying mechanisms. GHRH and GHRH analogues have been implicated in cell growth, wound healing, cell death, inflammation, immune functions, mood disorders, feeding behaviour, neuroprotection, diabetes mellitus and obesity, as well as cardiovascular, lung and neurodegenerative diseases and some cancers. The positive effects observed in preclinical models in vitro and in vivo strongly support the potential use of GHRH agonists and antagonists as clinical therapeutics.

Activated Growth Factor (AGF): An Advanced Modality of Platelet-Rich Plasma as a New Biological Agent for the Treatment of Degenerative and Traumatic Conditions

Platelet-rich plasma (PRP) has emerged as a promising therapeutic modality for various medical applications, particularly in regenerative medicine and wound healing. This is largely attributed to its rich concentration of growth factors (GFs) that play pivotal roles in tissue repair and regeneration. However, the inherent limitations of PRP, such as the variable GF concentrations and short-lived release kinetics, have spurred the development of advanced modalities to enhance its therapeutic efficacy. Activated growth factor (AGF) represents one such advancement, aiming to optimize the release and bioavailability of GFs from platelets. This comprehensive review delves into the biological mechanisms underlying AGF, its preparation methodologies, preclinical and clinical evidence supporting its use, and its potential applications in treating degenerative and traumatic conditions. Furthermore, it explores the advantages of AGF over conventional PRP and discusses future directions for research and clinical translation.

MANEJO DE FERIDAS EM COELHO ATRAVÉS DO USO DA PELE DE TILÁPIA LIOFILIZADA

The study addresses the importance of treating skin lesions in veterinary medicine, with an emphasis on wound healing in rabbits with pododermatitis, including the use of Nile tilapia skin as a therapeutic alternative for grafting after debridement of necrotic ulcers. Skin lesions can be caused by trauma, bites or other causes, compromising vital skin functions, such as protection and defense against infections. Tilapia skin is rich in type I collagen and has been highlighted as an accessible and effective biomaterial in the treatment of wounds, stimulating cell regeneration and healing. The work reports the case of a rabbit, named Paçoca, diagnosed with ulcerative pododermatitis in the left pelvic limb, a chronic condition that can lead to serious complications. The clinical signs of the pathology are pain, abdominal and limb alopecia, edema, ulcerative lesions, loss of joint mobility with the presence of osteolytic reactions. Pododermatitis in rabbits is often related to factors such as cage floor quality, excess weight, and sedentary lifestyle. The rabbit’s treatment included debridement of necrotic tissue and the application of tilapia skin as a graft. The tilapia skin was prepared through a rigorous sterilization and preservation process, involving immersion in specific solutions and the application of antibiotics. The use of this skin as an occlusive dressing helped stimulate growth factors essential for skin regeneration, such as fibroblasts and keratinocytes. The use of this biomaterial proved effective in the treatment of wounds with significant tissue loss, avoiding the need for sutures and promoting healing through the formation of new tissue. Postoperative follow-up included the use of antibiotics and anti-inflammatories, and treatment with tilapia skin contributed to the successful recovery. The study highlights the effectiveness of the biomaterial in the management of skin wounds in rabbits, especially in the recovery of lesions caused by ulcerative pododermatitis. Therefore, after treatment, the rabbit presented good healing, the wound evolved positively, with formation of granulation tissue and epithelialization.

Role of epigenetics in corneal health and disease.

Epigenetics plays a vital role in corneal health and diseases. Epigenetic changes regulate the expression of genes by altering the accessibility of chromatin via histone modifications, DNA methylation and miRNAs without altering DNA sequence. Ocular trauma and infections are common causes of corneal damage, vision impairment, and mono/bilateral blindness worldwide. Mounting literature shows that epigenetic modifications can modulate corneal clarity, function, and pathogenesis including inflammation, wound healing, fibrosis, and neovascularization. Additionally, epigenetic modifications can be targeted to reverse corneal pathologies and develop interventional therapies. However, current understanding on how epigenetic modifications lead to corneal abnormalities and diseases is limited. This review provides in-depth knowledge and mechanistic understanding of epigenetics alterations in corneal pathogenesis, and information on potential epigenetic targets for treatment of corneal diseases.

Risk factors for wound complications after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) compared to repeated liver resection - a propensity score matching analysis.

Sufficient liver function is crucial in extracellular matrix growth, hemostasis, and wound healing. Repeated abdominal surgery is a known risk factor for the development of wound complications. This study aimed to evaluate this high-risk constellation in patients undergoing associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) and repeated liver resections (RLR) in comparison to single liver resection (SLR). Forty patients who underwent ALPPS between 2011 and 2020 were evenly matched with patients undergoing RLR or SLR (n = 40 per group) using propensity scores. Postoperative outcomes were compared and factors associated with wound complications were analyzed. Postoperative wound complications were significantly more frequent in ALPPS group (p = 0.001). The reoperation rate was not significantly different between the three groups (p = 0.143). However, surgical reintervention due to wound complications occurred more frequently in the ALPPS group in relation to RLR and SLR (17.5% vs. 7.5% and 5% respectively). Length of stay was significantly longer in the ALPPS group (p = 0.033). ALPPS was an independent risk factor for postoperative wound complication (OR = 8.55, 95% CI:1.07-68.44, p = 0.043). Risk factor analysis identified age ≥ 60 years (OR = 27.64, 95% CI:3.09-246.75, p = 0.003), BMI ≥ 30kg/m2 (OR = 30.21, 95% CI:3.35-271.83, p = 0.002), and low postoperative albumin levels (OR = 168.41, 95% CI:7.76-3651.18, p = 0.001) as independent predictors of postoperative wound complications after major liver resection. Patients undergoing ALPPS and RLR are faced with a high risk of developing wound complications. Older age, obesity, a history of previous abdominal surgery, and a decreased postoperative albumin level were independent risk factors for wound complications.

Silk fibroin aerogels with AIE-featured berberine and MXene for rapid hemostasis and efficient wound healing.

Rapid hemostasis and wound healing are crucial in emergency trauma situations for saving patients' lives. Traditional hemostatic materials often have drawbacks such as slow hemostasis and susceptibility to post-hemostasis bacterial infections. Therefore, there is an urgent need for advanced wound dressing materials that can provide both rapid hemostasis and antimicrobial properties. In this study, we designed and fabricated a biocompatible hemostatic silk fibroin (SF) aerogel loaded with aggregation-induced emission (AIE)-featured berberine (BBr) and Ti3C2Tx MXene. The resulting SFMB aerogel demonstrates robust mechanical properties and a porous structure that enables quick hemostasis. This aerogel exhibits photodynamic and photothermal responses for antimicrobial activity, releases BBr upon light exposure to enhance bacterial-killing efficiency (99.33 % in vitro and 99.09 % in vivo), and effectively promotes the healing of infected wounds in vivo through combined photothermal/photodynamic antibacterial and anti-inflammatory mechanisms. Furthermore, the aerogel shows high hemocompatibility and cytocompatibility, supporting its potential biomedical applications. Overall, the synthesized SFMB aerogel holds promise for treating bacteria-infected wounds and for use in first aid applications in clinical settings.

A green approach to improve antibacterial properties of PVC/PVDF film doped by silver nanoparticles via nanosecond laser ablation for wound healing application.

Nanocomposite films of (30% PVC/70% PVDF) blend containing silver nanoparticles were synthesized via pulsed laser ablation route (PLA). Changes in physical characterization of PVC/PVDF blend before and after the incorporation of AgNPs have been studied. FTIR results confirms the interaction between AgNPs and PVC/PVDF. XRD results obtain the existence of peak at 38.42̊ in sample PVC/PVDF/Ag4 which confirm the embedded AgNPs in the high concentration. SEM photos confirm the distribution of silver nanoparticles on the surface of the sample in spherical shape which approved the dispersion of silver nanoparticles in PVC/PVDF blend. The inhibitory zone diameters observed for PVC/PVDF/Ag4 against Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, and Bacillus cereus were recorded as 11 ± 1, 10 ± 1, 15.7 ± 0.6, and 17.7 ± 0.6, respectively. PVC/PVDF/AgNPs nanocomposite film could be suggested for biomedical applications such as wound healing products.

Case Study on effect of Tamra Shalaka Agnikarma in the management of Kadara (Foot corn)

Ayurveda has a deep and all-encompassing understanding of life and health as a science. Over the course of many years, Ayurveda various branches have developed, with the primary focus being on disease prevention and treatment. There are a few illnesses known as Kshudra-Roga that have straightforward pathologies but are challenging to treat. Foot corn can be correlated with Kadara in Ayurveda, and it is one among the 44 Kshudra Rogas mentioned by Acharya Sushruta. Kshudra means little, diminutive or tiny means they are less severe when compared to Mahavyadhi. Acharya Bhoj describes it as Mamsakeela. Its form is identical to Koalmatra's. The pathophysiology of these conditions is caused by the vitiation of Meda and Rakta Dhatu and the dosha of Kapha and Vata. It is localized because the affected skin develops hyperkeratosis on the tips of the toes, the sole, and the inter phalangeal joints as a result of thorn puncture, continual friction, individual susceptibility, and other factors. Corn in western medical literature exhibit striking similarities in their presentations. Salicylic acid treatment, corn caps, and invasive techniques such as laser, chemical, electric, and cryotherapy cauterization, as well as surgical excision, are used in the management of corn. However, there is a greater probability of recurrence and the results of these operations are not good. However, the after effects of corn surgery are promising due to its recurrence and wound healing. Agnikarma (Cauterisation) is the best treatment for the Kadara. This present Case report describes a case of Kadara (Foot corn) diagnosed as per clinical features and managed successfully by Agnikarma.

Regulation of physicochemical properties of alginate-based hydrogels and preliminary applications in wound healing.

Alginate (Alg) hydrogels have demonstrated great potential in drug delivery, wound dressings, and tissue engineering. However, the practical applications of conventional Alg hydrogels suffer from rapid degradation, insufficient controlled drug release, and poor adhesion to tissues. In this paper, the physicochemical properties of Alg hydrogels were comprehensively modulated through chemical modification and the incorporation of various polymers. The results showed that introducing neutral polymers stabilized Alg hydrogels at room temperature. However, this stabilizing effect did not persist at 37 °C. The cationic chitosan (CS) can bind to Alg through electrostatic interaction. The incorporation of CS substantially improved the stability of Alg hydrogels and remarkably prolonged the release of BSA from hydrogels to 14 days at 37 °C. Meanwhile, introducing dopamine (DA)-modified Alg enhanced the adhesion of hydrogel to porcine skin. The optimized hydrogels were utilized to encapsulate platelet-rich plasma (PRP). The PRP-loaded composite hydrogel (2 wt% Alg, with a Ca2+/carboxyl group molar ratio of 0.2, a DA/carboxyl group molar ratio of 0.2, and a CS content of 30 % of Alg) exhibited an excellent therapeutic effect in the healing of rabbit shoulder cuff injury. These findings provide valuable insights into the modulation of physicochemical properties of hydrogels for biomedical applications.

Clearance of p21 highly expressing senescent cells accelerates cutaneous wound healing.

While senescent cells have detrimental roles in several contexts, they are highly heterogeneous. p16 highly expressing senescent cells have been reported to exert beneficial functions in wound healing. Here we use Xenium spatial transcriptomics to identify a distinct p21 highly expressing senescent population induced on wounding, with a pro-inflammatory profile. We find that clearing p21 highly expressing cells expedites wound closure and is partially mediated by NF-κB inhibition, thus enhancing our understanding of the multifaceted functions of senescence in tissue remodeling.

BN SO54 - Complex Management of a Gastrocutaneous Fistula Following Pancreatic Necrosectomy: A Case Report

Abstract Background Gastrocutaneous fistulas are rare but serious complications that can arise following the surgical treatment of necrotizing pancreatitis. This post-operatory complication can be refractory to conservative management and may be further aggravated by severe skin injuries and malnutrition. This case report describes the comprehensive and multidisciplinary approach of a challenging case of gastrocutaneous fistula, ultimately requiring re-intervention. Method A 78-year-old female with a history of severe necrotizing pancreatitis underwent pancreatic necrosectomy by laparotomy. Postoperatively, she developed a gastric fistula, initially repaired with a double-layered suture. Recurrence led to a gastrocutaneous fistula with continuous gastric drainage and chemical burn of the surrounding skin. Initial conservative management included insertion of a nasogastric tube for gastric decompression, followed by placement of a PEG tube to redirect the drainage and prevent further skin damage and an esophagojejunal feeding tube to bypass the fistula and maintain nutrition. Nevertheless, the fistula persisted, resulting in significant skin erosion and deterioration of the patient’s condition. Results Given the failure of conservative measures and a concurrent diagnosis of a pancreatic fistula, a surgical approach was deemed necessary. The patient was transferred to a specialized hospital center, where she underwent fistulectomy with partial gastrectomy and wound closure. Negative pressure wound therapy (NPWT) was applied to the ulcerated skin to promote healing. This approach led to the successful closure of the gastrocutaneous fistula and healing of the skin wound. The patient showed marked clinical recovery, with no signs of infection or fistula recurrence and the nutritional status was successfully managed through enteral feeding leading to a notable functional recovery. Conclusion This case underlines the complexity of managing gastrocutaneous fistulas, demonstrating the efficacy of combining surgical and supportive therapies, serving as a reference for similar future cases and emphasizing the need for comprehensive management strategies for complex postoperative complications.

GPD1L may inhibit the development of esophageal squamous cell carcinoma through the PI3K/AKT signaling pathway: bioinformatics analysis and experimental exploration.

Esophageal squamous carcinoma (ESCC) is the most prevalent pathological subtype of esophageal cancer (EC). It has the characteristics of significant local invasion, quick disease progression, high recurrence rates, and a dismal prognosis for survival. Phosphatidylinositol 3-kinase/serine-threonine kinase (PI3K/AKT) is a signaling system whose aberrant activation regulates downstream factors, leading to the promotion of cancer development. This study looks at a protein called Glycerol-3-phosphate dehydrogenase 1-like (GPD1L), which strongly affects the development of several cancers. However, its association with ESCC development and its underlying mechanisms are not clear. In this paper, we analyzed six ESCC transcriptome data obtained from the GEO database. We utilized bioinformatics technology and immunohistochemistry to differentially analyze GPD1L levels of mRNA and protein expression in ESCC and normal adjacent tissues. Furthermore, we conducted survival, co-expression, enrichment, immune infiltration and drug sensitivity analysis. Moreover, we further investigated the role and mechanism of GPD1L by Western Blot (WB), Cell Counting Kit-8 (CCK8), wound healing assay, Transwell assay, and flow cytometry. Finally, the addition of IGF-1, the activator of PI3K/AKT, could rescue the inhibitory effect of GPD1L on ESCC. The findings manifest that the expression of GPD1L was low in ESCC, and functional experiments showed that GPD1L promoted apoptosis in vitro while blocking cell migration, invasion, and proliferation. Based on mechanism research, GPD1L's impact on ESCC could be explained by its suppression of the PI3K/AKT signaling pathway's activation. To sum up, our findings imply that GPD1L may impede the initiation and advancement of ESCC via modulating the PI3K/AKT signaling pathway. GPD1L is considered to be a promising therapeutic target and biomarker to diagnose and treat ESCC.

Vascular endothelial growth factor facilitates the effects of telocytes on tumor cell proliferation and migration

BackgroundTelocytes, recently recognized as interstitial cells with a diverse range of potential functions, have attracted considerable attention for their involvement in tumorigenesis. Nevertheless, owing to certain challenges in the isolation and cultivation of telocytes, the research on telocytes has advanced rather slowly. Therefore, it is imperative to study the role and mechanisms of telocytes in tumors.MethodsWe improved the separation method and successfully isolated telocytes by exploiting the combination of cell adhesion and magnetic bead sorting. Telocytes conditioned medium was collected to culture tumor cells and explore the role and mechanisms of telocytes in tumors.ResultsMTT and colony formation assays demonstrated that telocytes promoted tumor cell proliferation. Wound healing experiments and transwell assays indicated that telocytes enhanced tumor cell migration. Real-time reverse transcriptase PCR analysis showed that the expression of E-cadherin was decreased, and that of Vimentin was notably increased. ELISA results revealed that telocytes secreted high levels of vascular endothelial growth factor (VEGF). And the promoting effects were alleviated by the VEGF inhibitor bevacizumab.ConclusionOur findings revealed that telocytes promoted tumor cell proliferation, migration, and angiogenesis through VEGF. Notably, these effects were inhibited by the addition of bevacizumab. In conclusion, our findings illuminated the role of telocytes in promoting tumor progression, and confirmed their crucial regulatory role in the growth of tumor cells.
