Eccrine poroma versus eccrine porocarcinoma: a comparative study of clinicopathological features.

Background: Eccrine porocarcinoma (EPC) is a rare cutaneous neoplasm, commonly arising from its benign counterpart, eccrine poroma (EP), but potential unrevealed clinicopathological differences between them are not well understood.

Objectives: This study aimed to identify clinicopathological features of EP and EPC and describe the factors that may be associated with the malignant transformation of EP by comparing the two groups.

Methods: A total of 37 cases of EP and 22 cases of EPC diagnosed between January 2017 and June 2023 were retrospectively reviewed, and the clinical and histopathological characteristics were compared using statistical methods.

HSP105 inhibition downregulates store-operated calcium entry and promotes acute UVB-induced tight junction disruption.

Background: Tight junction abnormalities are a common feature of inflammatory skin diseases such as psoriasis and atopic dermatitis and contribute to systemic immune responses. Evidence provided to date suggests that Heat shock protein 105 kDa (HSP105) exhibits significant protective effects in response to destructive external stimuli. However, its role in UV-induced skin tight junction remains to be fully understood.

Clinicopathological features of epithelioid hemangioma of 43 patients with long-term follow-up: A two-center retrospective study.

Epithelioid hemangioma (EH) is a rare angioproliferative disorder for which histopathology is the main approach to diagnosis. The tendency to recur is of concern to clinicians and patients. The factors associated with recurrence have been sporadically reported and a large-scale cohort study has been lacking.

Use of HSP105 in the Differential Diagnosis of Basaloid Skin Tumors: A Study of 73 Cases.

Background: Basaloid skin tumors include subtypes of basal cell carcinoma (BCC) and the basaloid variant of squamous cell carcinoma (SCC). Due to their similarity in pathology and clinical presentation, their diagnosis is not straightforward. The aim of this study was to analyze the immunohistochemical expression of HSP105 in basaloid skin tumors, which include BCC, basosquamous carcinoma (BSC), metatypical basal cell carcinoma (MBCC), basaloid squamous cell carcinoma (BSCC), BCC with squamous differentiation as well as conventional SCC.

The shared biomarkers and immune landscape in psoriatic arthritis and rheumatoid arthritis: Findings based on bioinformatics, machine learning and single-cell analysis.

Objective: Psoriatic arthritis (PsA) and rheumatoid arthritis (RA) are the most common types of inflammatory musculoskeletal disorders that share overlapping clinical features and complications. The aim of this study was to identify shared marker genes and mechanistic similarities between PsA and RA.

Methods: We utilized datasets from the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs) and perform functional enrichment analyses.

Kimura's disease treated with dupilumab: A case report and literature review.

Background: Kimura's disease (KD) is a rare chronic inflammatory disorder characterised by painless, deep subcutaneous nodules that most commonly affect the head and neck region of Asian men. Due to high relapse rates and side effects of current therapies, the treatment of KD is challenging.

Objectives: To present a case of KD that was successfully treated with dupilumab and to review the literature with a focus on the evaluation of the efficacy and safety of dupilumab in KD.

Glial Activation, Mitochondrial Imbalance, and Akt/mTOR Signaling May Be Potential Mechanisms of Cognitive Impairment in Heart Failure Mice.

Heart failure (HF) is a major health burden worldwide, with approximately half of HF patients having a comorbid cognitive impairment (CI). However, it is still unclear how CI develops in patients with HF. In the present study, a mice model of heart failure was established by ligating the left anterior descending coronary artery.

HSP105 suppresses the progression of cutaneous squamous cell carcinoma by activating the P53 signaling pathway.

Cutaneous squamous cell carcinoma (cSCC) is a common type of nonmelanoma skin cancer with a very high incidence. Heat shock proteins (HSPs) are involved in abnormal proliferation, invasion and apoptosis of tumor cells. Whether HSP105 acts as a promoter or inhibitor of cSCC remains to be further explored.

Sildenafil increases AAV9 transduction after a systemic administration and enhances AAV9-dystrophin therapeutic effect in mdx mice.

Adeno-associated virus (AAV) vectors have been successfully used to deliver genes for treating rare diseases. However, the systemic administration of high AAV vector doses triggers several adverse effects, including immune response, the asymptomatic elevation of liver transaminase levels, and complement activation. Thus, improving AAV transduction and reducing AAV dosage for treatment is necessary.

Cognitive impairment in patients with heart failure: molecular mechanism and therapy.

Heart failure (HF) is associated with multiple organ dysfunction and many comorbidities. Its incidence is high among the elderly and is a major health burden worldwide. Cognitive impairment (CI) is highly prevalent in older patients with HF, which is an abnormality in one or more of the items of cognition, attention, memory, language, psychomotor function, and visual spatial acuity.

Effects of Gentiana delavayi Flower Extract on APP Processing in APP/PS1 CHO Cells.

Gentiana delavayi Franch. (Gentianaceae) as an ethnomedicinal plant contains a variety of effective active ingredients and exhibits diverse pharmacological actions, such as hepatoprotective, anti-inflammatory and central nervous system effects. In this study we investigated the influence of G.

N-stearoyl-l-Tyrosine inhibits the cell senescence and apoptosis induced by HO in HEK293/Tau cells via the CB2 receptor.

Although considerable energy and money have been spent trying to inhibit Aβ production and its related metabolic enzyme activities, there are still no drug treatments available to cure even slow for Alzheimer's disease. Therefore, tau protein has been focused recently as the new target for the treatment of Alzheimer's disease. The transfected human embryonic kidney 293 (HEK 293) cells with or without Tau 411 plasmid were used to evaluate the effect of tau protein on cell viability.

Bioactive Dibenzo-α-pyrone Derivatives from the Endophytic Fungus Rhizopycnis vagum Nitaf22.

Six new dibenzo-α-pyrones, rhizopycnolides A (1) and B (2) and rhizopycnins A-D (3-6), together with eight known congeners (7-14), were isolated from the endophytic fungus Rhizopycnis vagum Nitaf22 obtained from Nicotiana tabacum. The structures of the new compounds were unambiguously elucidated using NMR, HRESIMS, TDDFT ECD calculation, and X-ray crystallography data. Rhizopycnolides A (1) and B (2) feature an uncommon γ-butyrolactone-fused dibenzo-α-pyrone tetracyclic skeleton (6/6/6/5), while rhizopycnin B (4) was the first amino group containing dibenzo-α-pyrone.

Chelation-Induced Polymer Structural Hierarchy/Complexity in Water.

Understanding nanoscale structural hierarchy/complexity of hydrophilic flexible polymers is imperative because it can be viewed as an analogue to protein-alike superstructures. However, current understanding is still in infancy. Herein the first demonstration of nanoscale structural hierarchy/complexity via copper chelation-induced self-assembly (CCISA) is presented.

Enhancement of Palmarumycins C(12) and C(13) production in liquid culture of endophytic fungus Berkleasmium sp. Dzf12 after treatments with metal ions.

The influences of eight metal ions (i.e., Na+, Ca2+, Ag+, Co2+, Cu2+, Al3+, Zn2+, and Mn4+) on mycelia growth and palmarumycins C(12) and C(13) production in liquid culture of the endophytic fungus Berkleasmium sp.

EIA application in China's expressway infrastructure: clarifying the decision-making hierarchy.

China's EIA Law came into effect in 2003 and formally requires road transport infrastructure development actions to be subject to Environmental Impact Assessment (EIA). EIAs (including project EIA and plan EIA, or strategic environmental impact assessment, SEA) have been being widely applied in the expressway infrastructure planning field. Among those applications, SEA is applied to provincial level expressway network (PLEI) plans, and project EIA is applied to expressway infrastructure development 'projects' under PLEI plans.
