KLHL24 associated cardiomyopathy: Gene function to clinical management.

Background: KLHL24 (Kelch-like protein 24) is a significant component of the ubiquitin-proteasome system (UPS), involved in regulating protein turnover through targeted ubiquitination and degradation. Germline mutations in KLHL24 gene have been known to cause Epidermolysis Bullosa Simplex characterized by skin fragility but has recently been found to cause Cardiomyopathy.

Main Body: Various cardiomyopathies, including hypertrophic cardiomyopathy and dilated cardiomyopathy, leading to abnormal protein degradation and affecting the stability and function of essential cardiac proteins which finally results into structural and functional abnormalities in cardiac muscle.

A retrospective study on the efficacy of pegfilgrastim-filgrastim combination regimen in the mobilization for autologous stem cell transplantation in lymphoma patients.

Background: The high mobilization failure rate with the mobilization strategy of combining chemotherapy and filgrastim (rhG-CSF) in autologous hematopoietic stem cell transplantation (auto-HSCT) in lymphomas is one of the unresolved issues. Whether the combination of polyethylene glycol filgrastim [pegfilgrastim (PEG-FIL), PEG-rhG-CSF] and filgrastim (FIL) improves the mobilization success rate and the timing of combination therapy has not been studied.

Methods: 107 lymphoma patients who received auto-HSCT were retrospectively enrolled and divided into groups of PEG+FIL and FIL.

Impaired Cardiac AMPK (5'-Adenosine Monophosphate-Activated Protein Kinase) and Ca-Handling, and Action Potential Duration Heterogeneity in Ibrutinib-Induced Ventricular Arrhythmia Vulnerability.

Background: We recently demonstrated that acute administration of ibrutinib, a Bruton's tyrosine kinase inhibitor used in chemotherapy for blood malignancies, increases ventricular arrhythmia (VA) vulnerability. A pathway of ibrutinib-induced vulnerability to VA that can be modulated for cardioprotection remains unclear.

Methods And Results: The effects of ibrutinib on cardiac electrical activity and Ca dynamics were investigated in Langendorff-perfused hearts using optical mapping.

Evaluation of the Impact of BaP Exposure on the Gut Microbiota and Allergic Responses in an OVA-Sensitized Mouse Model.

Background: Exposure to environmental pollutants, including benzo[a]pyrene (BaP), has been implicated in allergic diseases and intestinal microbiota homeostasis, but the environment-microbiota-immunity triangular relationship and to what extent BaP-induced remodeling of the gut microbiota contributes to intestinal allergic inflammation remain to be established.

Objectives: We investigated the impact of BaP on intestinal allergic inflammation and examined the relationship between this effect and gut microbiota dysbiosis. We explored the potential ability of intestinal bacteria to degrade BaP and alleviate cytotoxicity as a detoxification strategy to counteract the effects of BaP exposure.

S1PR1/S1PR3-YAP signaling and S1P-ALOX15 signaling contribute to an aggressive behavior in obesity-lymphoma.

Background: Excess body weight has been found to associate with an increased risk of lymphomas and some metabolic pathways are currently recognized in lymphomagenesis. Bioactive lipid metabolites such as sphingosine-1-phosphate (S1P) have been proposed to play an important role linking obesity and lymphomas. However, the underlying mechanism(s) of S1P signaling in obesity-lymphomagenesis have not been well addressed.

Von Hippel-Lindau syndrome with a rare complication of dilated cardiomyopathy: a case report.

Background: Von Hippel-Lindau (VHL) syndrome is an autosomal dominant hereditary disease affecting multiple organs, with pheochromocytoma in 26% of cases. However, VHL syndrome with congestive heart failure and dilated cardiomyopathy as the primary clinical manifestations has been rarely reported.

Case Presentation: A 35-year-old male patient was admitted to the hospital with dyspnea.

Overdrive pacing in the acute management of osimertinib-induced ventricular arrhythmias: A case report and literature review.

QT interval prolongation and ventricular arrhythmias (VAs) induced by osimertinib, a third-generation epidermal growth factor receptor tyrosine kinase inhibitor, are life-threatening complications. However, no consensus has been achieved regarding their management. Overdrive pacing has been shown to be effective in shortening the QT interval and terminating torsade de pointes (TdP).

Spatio-Temporal Niche of Sympatric Tufted Deer () and Sambar () Based on Camera Traps in the Gongga Mountain National Nature Reserve, China.

Clarifying the distribution pattern and overlapping relationship of sympatric relative species in the spatio-temporal niche is of great significance to the basic theory of community ecology and integrated management of multi-species habitats in the same landscape. In this study, based on a 9-year dataset (2012-2021) from 493 camera-trap sites in the Gongga Mountain National Nature Reserve, we analyzed the habitat distributions and activity patterns of tufted deer () and sambar (). (1) Combined with 235 and 153 valid presence sites of tufted deer and sambar, the MaxEnt model was used to analyze the distribution of the two species based on 11 ecological factors.

Clinical utility of left atrial strain in predicting atrial fibrillation recurrence after catheter ablation: An up-to-date review.

Rhythm control is the core part of the integrated management of atrial fibrillation (AF), especially in the early stages. Despite advances in catheter ablation (CA), the recurrence rate of AF after CA remains high. As a result, stratification and early management of AF recurrence after CA are critical.

Construction of Photoresponsive 3D Structures Based on Triphenylethylene Photochromic Building Blocks.

Photoresponsive materials have been widely used in sensing, bioimaging, molecular switches, information storage, and encryption nowadays. Although a large amount of photoresponsive materials have been reported, the construction of these smart materials into precisely prescribed complex 3D geometries is rarely studied. Here we designed a novel photoresponsive material methyl methacrylate containing triphenylethylene (TrPEF-MA) that can be directly used for digital light processing (DLP) 3D printing.

Intracellular calcium dysregulation has been reported to be involved in doxorubicin-induced cardiomyopathy (DICM). The cardioprotective role of RyR stabilizer dantrolene (Dan) on the calcium dynamics of DICM has not yet been explored.

Recent Development of Photodeformable Crystals: From Materials to Mechanisms.

Photodeformable materials are a class of molecules that can convert photon energy into mechanical energy, which have attracted tremendous attention in the last few decades. Owing to their unique photoinduced deformable properties, including fast light-response and diverse mechanical behaviors, photodeformable materials have exhibited great potential in many practical applications such as actuators, photoswitches, artificial muscles, and bioimaging. In this review, we sort out the current state of photodeformable crystals and classify them into six categories by molecular structures: diarylethenes, azobenzenes, anthracenes, olefins, triarylethylenes, and other systems.

Aspirin Positively Contributes to Intestinal Homeostasis and Delays Aging through Targeting Imd.

The intestine, a high-turnover tissue, plays a critical role in regulating aging and health in both vertebrates and invertebrates. Maintaining the epithelial barrier function of the intestine by preserving innate immune homeostasis significantly delays aging and prevents mortality. In an effort to explore effective chemicals and materials that can improve intestinal integrity, we performed a nonbiased screen utilizing as an animal model.

Unraveling an Innate Mechanism of Pathological Mineralization-Regulated Inflammation by a Nanobiomimetic System.

Pathological mineralization (PTM) often occurs under inflammation and affects the prognosis of diseases, such as atherosclerosis and cancers. However, how the PTM impacts inflammation has not been well explored. Herein, poly lactic-co-glycolic acid (PLGA)/gelatin/hydroxyapatite (HA) electrospun nanofibers are rationally designed as an ideal PTM microenvironment biomimetic system for unraveling the role of PTM on inflammation.
