188 (139 female; 49 male) genital swabs from patients with urogenital complaints (greater than 6 weeks), 69 (33 female; 36 male) conjunctival swabs from patients with chronic conjunctivitis and 14 swabs from newborns with acute conjunctivitis were tested for the presence of Chlamydia trachomatis (Ct) by inoculation in cell culture and visualisation by indirect immunofluorescence (IFT) with a monoclonal antibody and enzyme immunoassay (ELISA). Of the 271 specimens 20 (7.4%) were Ct positive by cell culture (IFT) and 18 (6.6%) were positive by ELISA. In 184 (97.9%) urogenital specimens results between cell culture (IFT) and ELISA agreed. With ELISA 4 further genital specimens were found to be Ct positive. In 59 (85.5%) conjunctival swabs of patients with chronic conjunctivitis results between cell culture (IFT) and ELISA agreed. By inoculation of cell culture (IFT) 6 (8.7%) more Ct positive specimens could be identified which were negative in ELISA. There was complete agreement between positive and negative Ct detection with cell culture (IFT) and ELISA in the cases of acute conjunctivitis.

Background: Postmenopausal women (PMW) who complete menopause at a late age (55+ years) have lower cardiovascular disease risk than PMW who complete menopause at a normal age (45-54 years). However, the influence of late-onset menopause on vascular endothelial dysfunction is unknown. Moreover, the mechanisms by which a later age at menopause may modulate endothelial function remain to be determined.

Calcium (Ca) is a universal signaling cation with a prominent role as second messenger in many different plant processes, including sexual reproduction. However, there is much less knowledge about the involvement of Ca during embryogenesis processes. In this work we performed a study of Ca levels during the different stages of microspore embryogenesis in , with special attention to how Ca can influence the occurrence of different embryogenic structures with different embryogenic potential.

The purpose of this study is to evaluate the optimum frequency of oscillatory fluid flow (OFF) for increasing osteogenesis in human dental pulp cells (DPCs) in an incubating rocking shaker. DPCs from 3 donors were cultured in an osteogenic induction medium (OIM) and mechanical stimulation was applied using an incubating rocking shaker at frequencies of 0 (control), 10, 20, 30, and 40 round per minute (RPM) for 1 h/day, 5 days/week. Cell proliferation was measured using total protein quantification, and osteogenic activity was measured by alkaline phosphatase (ALP) activity, calcium deposition, and collagen production on days 7, 14, and 21 of culture.

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte-microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined.

Cardiovascular disease is a leading cause of death worldwide. The differentiation of human pluripotent stem cells (hPSCs) into functional cardiomyocytes offers significant potential for disease modeling and cell-based cardiac therapies. However, hPSC-derived cardiomyocytes (hPSC-CMs) remain largely immature, limiting their experimental and clinical applications.
