Nowadays, antibiotics such as amoxicillin have been entered in water bodies. Nanofiltration has been proposed as an attractive technology for removal of antibiotics from aquatic environment instead of conventional wastewater treatment. In this paper, novel asymmetric flat sheet nanofiltration membranes were prepared via immersion precipitation technique and by using the poly(ethersulfone)/Brij®...

Vulvovaginal candidiasis (VVC) caused by Candida albicans affects a significant number of women during their reproductive ages. Clinical observations revealed that a robust vaginal polymorphonuclear neutrophil (PMN) migration occurs in susceptible women, promoting pathological inflammation without affecting fungal burden. Evidence to date in the mouse model suggests that a similar acute PMN mig...

The S100s are a large group of Ca(2+) sensors found exclusively in vertebrates. Transcriptomic and genomic data from the major radiations of mammals were used to derive the evolution of the mammalian S100s genes. In human and mouse, S100s and S100 fused-type proteins are in a separate clade from other Ca(2+) sensor proteins, indicating that an ancient bifurcation between these two gene lineages...

Many of the small, acidic, calcium binding S100 proteins present in the brain specifically map different anatomical regions and cell types and their overexpression is implicated in pathological changes. Similarly to other members of the S100 protein family, calcyclin (S100A6) is expressed in a cell specific manner and is found in subpopulations of neurons and astrocytes in the brain and in epit...

Three-dimensional structures of S100B, S100A1, S100A6 and S100A11 have shown that calcium binding to these proteins results in a conformational change allowing them to interact with many biological targets. The structures of some S100 proteins in the presence of peptide targets from Ndr kinase, p53, CapZ, annexins A1 and A2 and the Siah-1 Interacting Protein indicate there are at least three mo...

S100P protein consists of 95 amino acids with a molecular weight of 10.4 kDa. S100P is a Ca binding protein that belongs to S100 family ("Soluble in 100% saturated solution with ammonium sulfate") which was first isolated from human placenta and is therefore designated as "P". S100 family includes at least 26 members, which are thought to be expressed only in vertebrates and are present in a ti...

Heart failure (HF) represents the common endpoint of many different kinds of cardiopulmonary diseases. Essentially, loss of myocardium triggers a sequence of molecular, cellular and physiological responses leading to ventricular remodelling and the inability of the ventricle to maintain an output sufficient for the metabolic requirements of the tissues of the body [1]. Although these responses ...

OBJECTIVE Follicular dendritic cells (FDCs) and interdigitating dendritic cells (IDCs) are dendritic cells found in lymphoid follicles, reactive follicles and in lymphomas. The goal of this study was to evaluate the presence and distribution of FDCs and IDCs in oral lymphomas. MATERIAL AND METHODS Immunohistochemistry reactions were applied to 50 oral lymphomas using the antibodies anti-CD21,...

Malignant melanoma (MM) is a type of malignant tumor, which originates from neural crest melanocytes. MM progresses rapidly and results in a high mortality rate. The present study aims to investigate the expression of microphthalmia transcription factor (MITF), the S100 protein, and HMB-45 in MM and pigmented nevi. A total of 32 MM samples (including three skin metastasis, three lymph node meta...

The ontogeny of the neuro-insular complexes (NIC) and the islets innervation in human pancreas has not been studied in detail. Our aim was to describe the developmental dynamics and distribution of the nervous system structures in the endocrine part of human pancreas. We used double-staining with antibodies specific to pan-neural markers [neuron-specific enolase (NSE) and S100 protein] and to h...
