Immunohistochemical expression of IL-1β, IL-6, and NF-κβ in fibroids.

Uterine fibroids are benign tumors that occur in a large proportion of women and interfere with the proper functioning of this organ. One of the factors leading to these proliferative changes appears to be the appearance of extracellular matrix (ECM) fibrosis at the site of local inflammatory foci. Due to the potential impact of cytokines in this process, it is interesting to determine their expression levels in fibroids and surrounding tissues, which may contribute to a better understanding of the mechanisms leading to the formation of these tumors.

Immunohistochemical Expression of the SERPINA3 Protein in Uterine Fibroids.

Background: SERPINA3 (α-1-antichymotrypsin, AACT, ACT) is produced by the liver and released into plasma in an anti-inflammatory response and plays a role as a modulator of extracellular matrix (ECM) by inhibiting serine proteases. Numerous studies proved an increased level of SERPINA3 in many types of cancer, which could be linked to SERPINA3's anti-apoptotic function.

Aim: In the context of progressive ECM fibrosis during the development of uterine fibroids, which are one of the most common hypertrophic changes within the uterus, it is interesting to describe the level of SERPINA3 protein in this type of lesion and the surrounding tissues.

Cytotoxicity of gold nanoparticles to human lymphocytes: a comparison between rod-shaped and spherical nanoparticles.

Introduction: Gold nanoparticles (AuNPs) have unique properties that promise new and improved methods for targeting cancer treatment and diagnosis. However, despite their relatively high biocompatibility, AuNPs can negatively affect cell viability. Research indicates that the interactions with the plasma membrane and cellular uptake of AuNPs depend significantly on size, shape, and surface modifications.

IgG autoantibodies against ACE2 in SARS-CoV-2 infected patients.

How frequently autoantibodies against angiotensin-converting enzyme 2 (ACE2) occur in patients infected by SARS-CoV-2 is understudied and limited to investigations on a small sample size. The presence of these antibodies may contribute to the long-lasting effects of COVID-19 observed in some individuals, particularly if IgG-class antibodies would emerge in patients. This study assessed the prevalence of IgG autoantibodies against ACE2 in 1139 patients infected with SARS-CoV-2 and examined their relationship with severity, demographic characteristics, and status of vaccination against influenza.

Relationship between Humoral Response in COVID-19 and Seasonal Influenza Vaccination.

There is evidence that vaccination against seasonal influenza can improve innate immune responses to COVID-19 and decrease disease severity. However, less is known about whether it could also impact the humoral immunity in SARS-CoV-2 infected patients. The present study aimed to compare the SARS-CoV-2 specific humoral responses (IgG antibodies against nucleocapsid; anti-N, receptor binding domain; anti-RBD, subunit S2; anti-S2, and envelope protein; anti-E) between non-hospitalized, COVID-19 unvaccinated, and mild COVID-19 convalescent patients who were and were not vaccinated against influenza during the 2019/2020 epidemic season ( = 489 and = 292, respectively).

Immunohistochemical Expression of Vitamin D Receptor in Uterine Fibroids.

One of the many factors involved in the development of uterine fibroids is vitamin D deficiency. One aspect of this deficiency is decreased serum concentration of calcidiol-25(OH)D, a metabolite of D3 vitamin. The active form of vitamin D3, which arises after numerous enzymatic reactions, is calcitriol-1,25(OH)2D3; this compound is transported to various body tissues.

The role of selected molecular factors in ovarian cancer metastasis.

The main reason for treatment failure in ovarian cancer is chemoresistance and the presence of metastasis. Ascites, whichallows the physical movement of cancer cells, the lymphovascular pathway, and several molecular factors and signalling axes, are involved in metastasis. Ascites, with the involvement of cytokines and chemokines, MAPK/STAT1 and NOTCH as well as CXCL12/CXCR4 signaling pathways and circulating anoikis induces cancer dissemination, in particular to the peritoneum and omentum.
