The structures of the Caudovirales phage tails are key factors in determining the host specificity of these viruses. However, because of the enormous structural diversity, the molecular anatomy of the host recognition apparatus has been elucidated in only a number of phages. viruses vB_KleM_RaK2 (RaK2) and phiK64-1, which form a new genus according to the ICTV, have perhaps one of the most structurally sophisticated adsorption complexes of all tailed viruses described to date.

Objective: To determine the significance of tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-8 (MMP-8) in vaginally obtained amniotic fluid predicting fetal inflammatory response syndrome (FIRS) after preterm premature rupture of membranes (PPROM).

Methods: In this prospective case-control study, TNF-α and MMP-8 concentrations were evaluated in vaginally obtained amniotic fluid from women with PPROM at 22-34 weeks of pregnancy. Biomarkers' concentrations were determined using an enzyme-linked immunosorbent assay.

Preterm premature rupture of membranes (PPROM) interrupts normal lung development, resulting in neonatal respiratory morbidity. Although post-PPROM risks have been researched, only a few studies have investigated noninvasively obtained amniotic fluid (AF) to predict neonatal outcomes. In this study, we aimed to determine whether epidermal growth factor (EGF) in vaginally-collected AF is a significant predictor of neonatal respiratory outcomes after PPROM.

Background: The neutrophil-lymphocyte ratio (NLR) is easily calculated blood test parameter, which can be used as marker to predict many inflammatory disorders. The aim of this study was to assess and compare the NLR in maternal blood with the white blood cell (WBC) count and C-reactive protein (CRP) concentration for the prediction of histological chorioamnionitis.

Methods: This was a case-control study of 137 woman with preterm premature rupture of membranes (PPROM) at a gestational age between 22 and 34 weeks.

Introduction: This study was conducted to evaluate soluble Toll-like receptor 2 (sTLR-2) and soluble Toll-like receptor 4 (sTLR-4) levels in vaginally obtained amniotic fluid and investigate their value in the prediction of histological chorioamnionitis (HCA).

Material And Methods: This prospective case-control study included patients who had been diagnosed with preterm premature rupture of membranes before 34 weeks of gestation and were admitted to Vilnius University Hospital Santaros Klinikos. Free leaking amniotic fluid was obtained vaginally using a sterile speculum up to 48 h before delivery.

Background: Earlier chorioamnionitis diagnosis is crucial to improve maternal and neonatal health outcomes. This study was conducted to evaluate the inlerleukin-6 (IL-6), tumor necrosis factor α (TNF-α), and matrix metalloproteinase 8 (MMP-8) levels in vaginally obtained amniotic fluid to investigate their prognostic value and to determine the most appropriate cut-off values for the prediction of chorioamnionitis.

Methods: This case control study included women who were diagnosed with preterm premature rupture of the membranes before 34 weeks of gestation and were admitted to Vilnius University Hospital Santaros Klinikos.

This study investigated BCG masking dependency on the species of Mycobacterium through the immune response to the mycobacterial region of deletion 1 (RD-1) associated growth affecting proteins (GEP).To evaluate the effects of GEP, 8-week old female BALB/c mice were immunized with either the wild type Mycobacterium bovis (MBGEP) or the ATCC Mycobacterium avium subsp. avium (MAGEP) strain and then subjected to further exposure with Mycobacterium terrae or M.

Objective: Both Sjögren's syndrome (SS) and non-autoimmune sicca syndrome (nSS) can show symptoms of dry eyes and a dry mouth, and objective reductions in tear and saliva production. Dry eyes and dry mouth are frequent but they are distinct pathological entities that require diagnostic discrimination.

Methods: The aim of present study was to compare the serum levels of sICAM-1, TFF3, RANTES, adiponectin, and FGF in primary (pSS), secondary due to rheumatoid arthritis (sSS), non-autoimmune sicca syndrome (nSS), and healthy groups.

Aim: The aim of this study was to evaluate the expression of persistence of mumps virus and some cells that interact with viral infection in the focus of the autoimmune epithelitis and peripheral blood of Sjögren's syndrome patients in comparison to patients with rheumatoid arthritis (RA) and nonautoimmune sicca syndrome (nSS).

Materials And Methods: 126 patients (119 women and 7 men) were grouped into four groups: (1) patients with primary Sjögren's syndrome (pSS), (2) patients with secondary Sjögren's syndrome due to rheumatoid arthritis (sSS), (3) patients with rheumatoid arthritis (RA), and (4) patients with nonautoimmune sicca syndrome (nSS). Immunohistochemical analysis of immune response to the suggested silent persistence of mumps virus in the minor labial salivary gland biopsies and flow cytometric analysis of blood cells was done.

Etiology of Sjögren's syndrome (SS) is still unknown, but there is strong evidence that certain pathogens of bacterial or viral origin can incite autoimmune response. The aim of this study was to quantitatively evaluate changes of the main cell populations (dendritic cells, natural killer, natural killer T and cytotoxic T lymphocytes) presumably participating in virus clearance in peripheral blood of patients with primary SS (pSS). In analyzing cytotoxic T lymphocytes (CTL) populations we observed alterations in the frequency of highly cytotoxic effector CD8/57/27/45RA, less cytotoxic CD8/57/27/45RA effector cells and cytotoxic memory CD8/57/27/45RA effector cells.

Purpose of this study was to evaluate the lymphocyte populations' distribution changes in peripheral blood of patients with primary Sjögren's syndrome (pSS). Lymphocyte populations' distribution changes in peripheral blood of pSS patients were investigated in 52 patients with pSS and in 28 healthy controls by flow cytometry. We found decreased absolute count of CD3(+) T cell population in pSS patients.

Our aim is to evaluate the complement component C4 (C4) and its fragment C4d (C4d) levels, focusing on their associations with other markers of B cells' activity in patients with primary Sjögren's syndrome (pSS). Humoral factors C4, C4d, B cell-activating factor (BAFF), κ and λ free light chains (FLCs) and IgG (by immunoassay) were investigated in 58 patients with pSS and in 28 healthy controls. We observed significantly higher levels of BAFF, κ and λ FLC and IgG, and significantly lower level of C4 in pSS patients, while the level of C4d was similar in the both groups.
