Near Infrared Biomimetic Hybrid Magnetic Nanocarrier for MRI-Guided Thermal Therapy.

Cell-membrane hybrid nanoparticles (NPs) are designed to improve drug delivery, thermal therapy, and immunotherapy for several diseases. Here, we report the development of distinct biomimetic magnetic nanocarriers containing magnetic nanoparticles encapsulated in vesicles and IR780 near-infrared dyes incorporated in the membranes. Distinct cell membranes are investigated, red blood cell (RBC), melanoma (B16F10), and glioblastoma (GL261). Hybrid nanocarriers containing synthetic lipids and a cell membrane are designed. The biomedical applications of several systems are compared. The inorganic nanoparticle consisted of Mn-ferrite nanoparticles with a core diameter of 15 ± 4 nm. TEM images show many multicore nanostructures (∼40 nm), which correlate with the hydrodynamic size. Ultrahigh transverse relaxivity values are reported for the magnetic NPs, 746 mM-1s-1, decreasing respectively to 445 mM-1s-1 and 278 mM-1s-1 for the B16F10 and GL261 hybrid vesicles. The ratio of relaxivities r2/r1 decreased with the higher encapsulation of NPs and increased for the biomimetic liposomes. Therapeutic temperatures are achieved by both, magnetic nanoparticle hyperthermia and photothermal therapy. Photothermal conversion efficiency ∼25-30% are reported. Cell culture revealed lower wrapping times for the biomimetic vesicles. In vivo experiments with distinct routes of nanoparticle administration were investigated. Intratumoral injection proved the nanoparticle-mediated PTT efficiency. MRI and near-infrared images showed that the nanoparticles accumulate in the tumor after intravenous or intraperitoneal administration. Both routes benefit from MRI-guided PTT and demonstrate the multimodal theranostic applications for cancer therapy.

Nanosponges-Road Less Explored Changing Drug Delivery Approach: An Explicative Review.

Nanotechnology exhibits a wide range of applications in the domain of disease therapy, diagnosis, biological detection, and environmental safeguards. The cross-linked polymeric nanosponges (NSs) are a nanoscale drug carrier system with a 3D porous structure and high entrapment efficacy. NSs up to the fourth generation are currently accessible and can serve as a delivery system for both hydrophilic and hydrophobic drugs. The delivery system exhibits superiority over alternative methods due to its ability to achieve controlled and targeted drug delivery. The colloidal structure of NSs facilitates the encapsulation of a wide range of agents such as proteins and peptides, enzymes, antineoplastic drugs, volatile oil, vaccines, DNA, etc. NSs efficiently overcome the challenges associated with drug toxicity and poor aqueous solubility. NS formulations have been explored for various applications like gaseous encapsulation, enzyme immobilization, antifungal therapy, poison absorbent, water purification, etc. This review provides a comprehensive analysis regarding methods of synthesis, distinct polymeric NSs, mechanism of drug release, factors affecting NS development, applications, and patents filed in the field of NSs. Herein, the recently developed NS formulations, their potential in cancer therapy, and current progressions of NS for SARS-CoV-2 management are also deliberated with special attention, focusing on the significant challenges and future directions.

Nanotechnology Based Therapeutic Approach in Alzheimer's

Alzheimer's disease is a neurodegenerative disorder that ultimately results from the accumulation of beta-amyloid plaques in the brain. The Alzheimer's disease cannot be prevented or cured at this time, and there is no recognised alternative. The medicinal solutions that are currently available can merely slow down its development. However, nanotechnology has demonstrated its applications in the medical field, and it demonstrates a great deal of promise in the treatment of Alzheimer's disease. In particular, it has shown significant promise in the detection of the condition and the development of an alternative technique to cure it. It is necessary for the medication delivery system to have the capability of penetrating and crossing the blood-brain barrier in order to accomplish this need. On the other hand, greater research is necessary in order to discover and overcome these limitations, which have the potential to improve drug absorption while simultaneously reducing toxicity and adverse effects. Certain nanotechnology-based techniques to treating Alzheimer's disease include regenerative medicine, neuroprotection, and stem cell regeneration. These are just few of the emerging approaches. This article's goal is to take a look at nanotechnology from every angle, including its advantages and disadvantages and how it's helping with neurodegenerative disease research and therapy.

Reformulating lipid nanoparticles for organ-targeted mRNA accumulation and translation

Fully targeted mRNA therapeutics necessitate simultaneous organ-specific accumulation and effective translation. Despite some progress, delivery systems are still unable to fully achieve this. Here, we reformulate lipid nanoparticles (LNPs) through adjustments in lipid material structures and compositions to systematically achieve the pulmonary and hepatic (respectively) targeted mRNA distribution and expression. A combinatorial library of degradable-core based ionizable cationic lipids is designed, following by optimisation of LNP compositions. Contrary to current LNP paradigms, our findings demonstrate that cholesterol and phospholipid are dispensable for LNP functionality. Specifically, cholesterol-removal addresses the persistent challenge of preventing nanoparticle accumulation in hepatic tissues. By modulating and simplifying intrinsic LNP components, concurrent mRNA accumulation and translation is achieved in the lung and liver, respectively. This targeting strategy is applicable to existing LNP systems with potential to expand the progress of precise mRNA therapy for diverse diseases.

Total synthesis of [β-HIle]2-nodupetide: effect of ester to amide substitution on its antimicrobial activity.

The increasing prevalence of deaths due to multidrug-resistant bacteria (MDRB) in infectious disease therapy has become a global health concern. This led to the development of new antimicrobial therapeutic agents that can combat resistance to pathogenic bacteria. The utilization of natural peptide compounds as potential antimicrobial agents is very promising. Nodupetide, a cyclodepsipeptide with very strong antimicrobial activity against Pseudomonas aeruginosa was isolated from the fermentation of Nodulisporium sp. Unfortunately, one of its residues (3S,4S)-3-hydroxy-4-methylhexanoic acid (HMHA) is not commercially available and the synthesis strategies applied have not been successful. Hence, we synthesized its cyclopeptide analogue [β-HIle]2-nodupetide by replacing HMHA with isoleucine homologue. A combination of solid- and solution-phase peptide synthesis was successfully carried out to synthesize [β-HIle]2-nodupetide with an overall yield of 10.4%. The substitution of HMHA with β-homoisoleucine (β-HIle) changed the ester bond into an amide bond in nodupetide's backbone. The analogue was considerably inactive against Pseudomonas aeruginosa. It can be concluded that the ester bond is crucial for the antimicrobial activity of nodupetide.

Intrajejunal levodopa in Parkinson's disease: Optimization of PEG application

The various forms of Percutaneous Endoscopic Gastrostomy (PEG) are highly relevant in neurology, as pump-administered intrajejunal levodopa application is one of the indispensable forms of therapy in advanced Parkinson's disease. Optimal PEG placement and follow-up are therefore significant for the success of the therapy. However, the standard intrajejunal administration of levodopa gel via a JET-PEG, i. e. a PEG with an internal catheter inserted into the jejunum, is not without problems for various reasons. In particular, the considerable cumulative complication rates demand a reconsideration of the situation. The very limited absorption area of the drug in the region of the flexura duodenojejunalis must also be taken into account. Causes of complications are predominantly a non-optimal application technique of PEG and internal catheter as well as the frequent lack of an adequate follow-up. In this paper, the details of a modified and optimized application technique compared to the conventional techniques are presented. These new methods have proved their usefulness in clinical applications for years, and additionally a new application form, the Hybrid-PEG, is presented. However, many of the details derived from anatomical/physiological, surgical and endoscopic aspects must be strictly observed during the application in order to reduce or avoid minor and major complications. In particular, problems are caused by local infections in the area of the insertion point of the PEG including peritonitis, leaks and buried bumper syndrome (BBS). The relatively frequent dislocations of the internal catheter also prove to be particularly troublesome. These can ultimately be avoided by clip fixation of the catheter tip down in the jejunum. In particular, the use of the newly developed Hybrid-PEG, a combination of endoscopically controlled gastropexy with three sutures and subsequent central thread-pull-through of the PEG tube, can significantly reduce the complication rate and thus achieve a decisive improvement for patients. The aspects discussed here are highly relevant for all those involved in the therapy of advanced Parkinson's disease. Trustful interdisciplinary collaboration between neurology and endoscopy/surgery/gastroenterology is a prerequisite for good clinical outcomes.

Effects of additional physical exercise on the nutritional status and disease progression during the low-protein diet in Chronic Kidney Disease Patients: a systematic review and meta-analysis.

Low-protein diet (LPD) is the core of dietary and nutritional therapy for non-dialysis chronic kidney disease (CKD) patients. In addition, physical exercise could prevent and treat various illnesses and chronic diseases. The objective of the study was to search for and appraise evidence on the effect of additional physical exercise on patients' nutritional status and indicators of disease progression when compared with the LPD alone. PubMed Central, Embase, Cochrane, and Web of Knowledge for randomized controlled trials (published between January 1, 1956 and May 17, 2023) were searched. A total of 8698 identified studies, 9 were eligible and were included in our analysis (N = 250 participants). Compared with the LPD alone, additional physical exercise reduced serum creatinine by a mean of -0.21 mg/dL (95% CI -0.39 to -0.03) in CKD patients. Similarly, blood pressure decreased after physical exercise, with systolic blood pressure decreasing by -7.05 mm Hg (95% CI -13.13 to -0.96) and diastolic blood pressure decreasing by -5.31 mm Hg (95% CI -7.99 to -2.62). Subgroup analyses revealed that resistance exercise (RE) was effective in decreasing estimated glomerular filtration rate (eGFR) of -1.71 mL/min per 1.73 m² (95% CI -3.29 to -0.14). In addition, the VO2peak increasing by 2.41 mL/kg/min (95% CI 0.13 to 4.70) when physical exercise was continued for 24 weeks. The above results suggest that the LPD with additional physical exercise care is more beneficial for patients with CKD.

Small extracellular vesicles derived from microRNA-22-3p-overexpressing mesenchymal stem cells protect retinal ganglion cells by regulating MAPK pathway

Glaucoma is the leading cause of irreversible blindness and is characterized by progressive retinal ganglion cell (RGC) loss and retinal nerve fiber layer thinning. Currently, no existing treatment is effective for the preservation of RGCs. MicroRNA-22-3p (miR22) and small extracellular vesicles derived from mesenchymal stem cells (MSC-sEVs) have neuroprotective effects. In this study, we apply miR22-overexpressing MSC-sEVs in an N-methyl-D-aspartic acid (NMDA)-induced RGC injury model to assess their short-term therapeutic effects and explore the underlying mechanisms. We find that mice in the miR22-sEVs-treated group have thicker retinas, fewer apoptotic cells, more reserved RGCs, better retinal function, and lower expression levels of Bax and caspase-3. MiR22-sEVs treatment promotes viability, inhibits apoptosis and inhibits Bax and caspase-3 expression in RGC-5 cells. MiR22 targets mitogen-activated protein kinase kinase kinase 12 to inhibit apoptosis by regulating the mitogen-activated protein kinase (MAPK) signaling pathway. Collectively, our results suggest that miR22-sEVs ameliorate NMDA-induced RGC injury through the inhibition of MAPK signaling pathway-mediated apoptosis, providing a potential therapy for glaucoma and other diseases that involve RGC damage.

Advances in inhaler therapy for asthma and chronic obstructive pulmonary disease: a comprehensive review of Fostair™ and Trimbow™.

The management of asthma and chronic obstructive pulmonary disease (COPD) poses considerable challenges due to the intricate nature of these respiratory conditions. Fostair™ and Trimbow™, two pressurized metered dose inhalers, have emerged as noteworthy therapeutic options for treating both asthma and COPD. Fostair combines an inhaled corticosteroid, specifically beclometasone dipropionate, with a long-acting beta2-agonist, formoterol fumarate dihydrate, offering a dual-action approach to mitigate airway inflammation and bronchoconstriction. Conversely, Trimbow integrates a tri-particulate formulation consisting of beclometasone dipropionate, formoterol fumarate dihydrate, and glycopyrronium bromide, providing a comprehensive strategy to target the pathophysiology of COPD and asthma. Recent clinical trials have underscored Trimbow's superior efficacy compared with Fostair, particularly in terms of reducing exacerbation rates and enhancing lung function. However, despite their therapeutic promise, both inhalers encounter challenges, including limited generalizability of study findings and a disparity between in vitro and human trial results. This literature review offers an in-depth analysis of Fostair and Trimbow, delving into their mechanisms of action, clinical applications, and outcomes in human studies for asthma and COPD. Additionally, the review discusses the role of combination therapy in managing respiratory diseases and underscores the necessity for further research to address existing knowledge gaps and optimize therapeutic outcomes.

Proactive Therapeutic Drug Monitoring Is Associated With Increased Drug Persistence in Patients With Inflammatory Bowel Disease Treated With Intravenous Vedolizumab.

There are limited data regarding therapeutic drug monitoring (TDM) of non-anti-tumor necrosis factor therapy in inflammatory bowel disease (IBD). This study aimed to evaluate the efficacy of proactive TDM in IBD patients treated with intravenous (iv) vedolizumab (VDZ). This single-center retrospective cohort study included consecutive IBD patients treated with maintenance iv VDZ therapy undergoing TDM from November 2016 to March 2023. Patients were followed through June 2023 and were divided in to 2 groups: those who had at least 1 proactive TDM vs those who underwent only reactive TDM. A survival analysis was performed to evaluate drug persistence, defined as no need for drug discontinuation due to loss of response, serious adverse event, or an IBD-related surgery. The study population consisted of 94 patients (proactive TDM, n = 72) with IBD (ulcerative colitis, n = 53). Patients undergoing at least 1 proactive TDM compared with patients having only reactive TDM demonstrated a higher cumulative probability of drug persistence (Log-rank P < .001). In multivariable Cox proportional hazard regression analysis, at least 1 proactive TDM was the only factor associated with drug persistence (hazard ratio, 14.3; 95% confidence interval [CI], 3.8-50; P < .001). A ROC analysis identified a VDZ concentration of 12.5 µg/mL as the optimal drug concentration threshold associated with drug persistence (area under the ROC curve: 0.691; 95% CI, 0.517-0.865; P = .049). In this single-center retrospective study reflecting real-life clinical practice, proactive TDM was associated with increased drug persistence in patients with IBD treated with iv VDZ.

Revolution in diet therapy for inflammatory bowel disease.

Until recently, diet as a therapeutic tool to treat inflammatory bowel disease (IBD) has not been proven effective. Nearly a century in the making we are in the grips of a revolution in diet therapies for IBD, driven by emerging data revealing diet as a key environmental factor associated with IBD susceptibility, and observational studies suggesting that dietary intake may play a role in the disease course of established IBD. This review summarizes the current evidence for diets trialed as induction and maintenance therapy for IBD. For Crohn's disease, exclusive enteral nutrition and the Crohn's disease exclusion diet with partial enteral nutrition are supported by emerging high-quality evidence as induction therapy, but are short-term approaches that are not feasible for prolonged use. Data on diet as maintenance therapy for Crohn's disease are conflicting, with some studies supporting fortification, and others suppression, of certain food components. For ulcerative colitis, data are not as robust for diet as induction and maintenance therapy; however, consistent themes are emerging, suggesting benefits for diets that are plant-based, high in fiber and low in animal protein. Further studies for both Crohn's disease and ulcerative colitis are eagerly awaited, which will allow specific recommendations to be made. Until this time, recommendations default to population based healthy eating guidelines.

Basics in diagnostics and therapy of allergic diseases for ENT consultations

Allergies play a pivotal role in the daily practice of ENT specialists. Allergic symptoms induced by inhalant allergens are widespread in the population and can manifest through a wide range of symptoms, including rhinorrhea, sneezing, conjunctival redness, cough and dyspnea. Inconsistent diagnosis and treatment of allergic conditions can lead to reduced quality of life, decreased work performance, and socioeconomically significant secondary diseases. In addition to the medical history, the skin prick test and serological IgE diagnostics are the most important diagnostic procedure for detecting type-I allergies. To clarify clinical relevance, molecular diagnostics and nasal provocation testing may be employed. The key to effective treatment lies in a comprehensive allergological diagnosis coupled with a detailed patient history. General treatment recommendations such as allergen avoidance and nasal irrigation should complement pharmacological therapy. In the treatment of allergic rhinitis topical steroids are first line treatment options. The primary goal of treatment is symptom control, and if control is insufficient, causal therapy through specific allergen immunotherapy is recommended. Challenges in the ENT clinic involve selecting the necessary diagnostics and appropriate, effective treatments. Hence, using diagnostic and treatment algorithms, as well as standardized patient history questionnaires, can serve as invaluable tools in daily patient interactions, especially considering limited time availability.

Gegen Qinlian decoction inhibited M1 macrophage polarization and ulcerative colitis progression through regulating histone lactylation

Ulcerative colitis (UC) is a persistent inflammatory condition affecting the bowels. Gegen Qinlian decoction (GQD) has been widely used in the therapy of gastrointestinal diseases. We investigated the protective impacts and mechanism of GQD against UC. To establish the UC model, dextran sulfate sodium (DSS) was utilized. The disease activity index (DAI), colon length and colonic pathology were assessed to examine the impacts of GQD on UC. The level of pan-lysine lactylation (Pan kla) and specific sites were detected using western blot. Then, the inflammatory factors and the oxidative stress parameters were measured via the corresponding kits, respectively. Our findings demonstrated that GQD suppressed the lactate generation and LDH activity. The western blot revealed that GQD inhibited the expression of Pan kla and specific sites of H3K18la, H3K23la, H4K8la, and H4K12la. Furthermore, the suppressive effects on inflammation and oxidative stress caused by GQD were counteracted upon the exogenous lactate. GQD suppressed the phenotypic differentiation of M1 macrophages by reducing the expression of M1 markers, which was also reversed by exogenous lactate. In conclusion, GQD effectively suppressed UC progression through histone lactylation. Our results broadened the theoretical basis for the clinical use of GQD.

White adipocytes in subcutaneous fat depots require KLF15 for maintenance in preclinical models.

Healthy adipose tissue is essential for normal physiology. There are 2 broad types of adipose tissue depots: brown adipose tissue (BAT), which contains adipocytes poised to burn energy through thermogenesis, and white adipose tissue (WAT), which contains adipocytes that store lipids. However, within those types of adipose, adipocytes possess depot and cell-specific properties that have important implications. For example, the subcutaneous and visceral WAT confers divergent risk for metabolic disease. Further, within a depot, different adipocytes can have distinct properties; subcutaneous WAT can contain adipocytes with either white or brown-like (beige) adipocyte properties. However, the pathways that regulate and maintain this cell and depot-specificity are incompletely understood. Here, we found that the transcription factor KLF15 is required for maintaining white adipocyte properties selectively within the subcutaneous WAT. We revealed that deletion of Klf15 is sufficient to induce beige adipocyte properties and that KLF15's direct regulation of Adrb1 is a critical molecular mechanism for this process. We uncovered that this activity is cell autonomous but has systemic implications in mouse models and is conserved in primary human adipose cells. Our results elucidate a pathway for depot-specific maintenance of white adipocyte properties that could enable the development of therapies for obesity and associated diseases.

Berberine Decreases Thrombosis Potential Induced by a High-choline Diet by Inhibiting CutC Enzyme.

Gut microbes influence thrombosis potential by generating trimethylamine N-oxide (TMAO). However, whether the antithrombotic effect of berberine is associated with TMAO generation remains unclear. The present study was designed to explore whether berberine decreases the TMAO-induced thrombosis potential and the possible mechanism underneath it. C57BL/6J female mice under a high-choline diet or standard diet were treated with/without berberine for 6 weeks. The TMAO level, carotid artery occlusion time following FeCl3 injury and platelet responsiveness were measured. The binding of berberine to the CutC enzyme was analysed with molecular docking, and molecular dynamics simulations were verified with enzyme activity assays. Results：The results showed that berberine increased the carotid artery occlusion time following FeCl3 injury and decreased the platelet hyperresponsiveness induced by a high-choline diet, both offset by intraperitoneal injection of TMAO. The effect of berberine on thrombosis potential was associated with decreasing the generation of TMAO by inhibiting the CutC enzyme. Targeting TMAO generation with berberine might be a promising therapy for ischaemic cardiac-cerebral vascular diseases.

Cinnamaldehyde-Treated Bone Marrow Mesenchymal-Stem-Cell-Derived Exosomes via Aqueous Two-Phase System Attenuate IL-1β-Induced Inflammation and Catabolism via Modulation of Proinflammatory Signaling Pathways

Osteoarthritis (OA) is a degenerative joint disorder that is distinguished by inflammation and chronic cartilage damage. Interleukin-1β (IL-1β) is a proinflammatory cytokine that plays an important role in the catabolic processes that underlie the pathogenesis of OA. In this study, we investigate the therapeutic efficacy of exosomes derived from untreated bone-marrow-derived mesenchymal stem cells (BMMSC-Exo) and those treated with cinnamaldehyde (BMMSC-CA-Exo) for preventing the in vitro catabolic effects of IL-1β on chondrocytes. We stimulated chondrocytes with IL-1β to mimic the inflammatory microenvironment of OA. We then treated these chondrocytes with BMMSC-Exo and BMMSC-CA-Exo isolated via an aqueous two-phase system and evaluated their effects on the key cellular processes using molecular techniques. Our findings revealed that treatment with BMMSC-Exo reduces the catabolic effects of IL-1β on chondrocytes and alleviates inflammation. However, further studies directly comparing treatments with BMMSC-Exo and BMMSC-CA-Exo are needed to determine if CA preconditioning can provide additional anti-inflammatory benefits to the exosomes beyond those of CA preconditioning or treatment with regular BMMSC-Exo. Through a comprehensive molecular analysis, we elucidated the regulatory mechanisms underlying this protective effect. We found a significant downregulation of proinflammatory signaling pathways in exosome-infected chondrocytes, suggesting the potential modulation of the NF-κB and MAPK signaling cascades. Furthermore, our study identified the molecular cargo of BMMSC-Exo and BMMSC-CA-Exo, determining the key molecules, such as anti-inflammatory cytokines and cartilage-associated factors, that may contribute to their acquisition of chondroprotective properties. In summary, BMMSC-Exo and BMMSC-CA-Exo exhibit the potential as therapeutic agents for OA by antagonizing the in vitro catabolic effects of IL-1β on chondrocytes. The regulation of the proinflammatory signaling pathways and bioactive molecules delivered by the exosomes suggests a multifaceted mechanism of action. These findings highlight the need for further investigation into exosome-based therapies for OA and joint-related diseases.

Current and future microbiome-based therapies in inflammatory bowel disease.

The role of the microbiome and dysbiosis is increasingly recognized in the pathogenesis of inflammatory bowel disease (IBD). Intestinal microbiota transplant (IMT), previously termed fecal microbiota transplant has demonstrated efficacy in restoring a healthy microbiome and promoting gut health in recurrent Clostridioides difficile infection. Several randomized trials (RCTs) highlighted IMT's potential in treating ulcerative colitis, while smaller studies reported on its application in managing Crohn's disease and pouchitis. This review delves into the current understanding of dysbiosis in IBD, highlighting the distinctions in the microbiota of patients with IBD compared to healthy controls. It explores the mechanisms by which IMT can restore a healthy microbiome and provides a focused analysis of recent RCTs using IMT for inducing and maintaining remission in IBD. Lastly, we discuss the current knowledge gaps that limit its widespread use. The body of evidence supporting the use of IMT in IBD is growing. The lack of a standardized protocol impedes its application beyond clinical trials. Further research is needed to identify patient profile and disease phenotypes that benefit from IMT, to delineate key donor characteristics, optimize the delivery route, dosage, and frequency.
