Cystic lesions were found in the telencephalic germinal layer of 12 newborn babies. According to their location, the cysts could be divided into three groups: anterior, middle or thalamostriate, and posterior. The histological appearance of all cysts was essentially the same, but in three cases the germinal layer had a peculiar alveolar type of microcystic degeneration. A constant feature was t...
objective: mitochondria is a critical organelle within the cell and has important role in the oocyte development, thus the aim of this study was the comparison of mitochondrial distribution within the mouse oocyte at germinal vesicle (gv), germinal vesicle breakdown (gvbd) and metaphase ii (mii) stages using laser confocal microscopy (lscm). materials and methods: after superovulation of adult...
Background: Varicocele (VCL) exerts its impact via enhancing inflammation and down-regulating testicular endocrine and antioxidant statuses. Celecoxib (CCB) is a non-steroidal anti-inflammatory drug (NSAID), which its effects based on the inhibition of cyclooxygenase (COX) enzymes. On the hand, silymarin (SMN) is known for its remarkable anti-oxidative impact. Therefore, present study was desig...
objective(s): bone marrow-derived mesenchymal stem cells (bm-mscs) potentials make them appropriate for cell therapy including ability of differentiation and release of anti-inflammatory cytokines and growth factors secreta. for treatment of azoospermia to induce proliferation and differentiation of germ cells, mscs transplantation has been introduced. the aim of the present experimental case-c...
The germinal plate of 5- to 12-day-old embryos of the leech Hirudo medicinalis consists of an anterior and a posterior sector that differ both structurally and developmentally. The posterior sector includes the five pairs of teloblasts and five paired longitudinal bandlets of stem cells and their descendant blast cells. The mesoteloblast pair and their descendant cells of the m bandlet divide s...
BACKGROUND The atheromodulating activity of B cells during the development of atherosclerosis is well documented, but the mechanisms by which these cells are regulated have not been investigated. METHODS AND RESULTS Here, we analyzed the contribution of Qa-1-restricted CD8(+) regulatory T cells to the control of the T follicular helper-germinal center B-cell axis during atherogenesis. Genetic...
Diffuse large B-cell lymphoma (DLBCL) represents the most frequent lymphoma subtype and is considered a heterogeneous diagnostic category [1]. Using gene expression profiling, two major molecular subtypes termed germinal centre B-cell-like (GCB) DLBCL and activated B-cell-like (ABC) DLBCL can be distinguished [2]. Their gene expression profiles suggest that they arise from B-cells at different ...
