background: endometrial integrin expression changes might be a reason for implantation failure in polycystic ovarian syndromes (pcos). objective: assessment of integrin genes and proteins expression upon endometrium in the pcos experimental mouse model was the main goal of this study. materials and methods: 30 nmri female mice were equally divided into control, experimental (pcos; received estr...

central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra-gnathic incidence is rare.multifocal cgcgs of the jaws are very rare and suggestive of systemic diseases such as hyperparathyroidism,an inherited syndrome such as noonan-like multiple giant cell lesion syndrome or other disorders.very few c...

congenital myasthenic syndromes (cms) are a group of diseases caused by genetic defects affecting neuromuscular transmission and are heterogeneous in inheritance and pathophysiology. these are classified as: 1. presynaptic defects: including choline acetyl transferase deficiency, paucity of synaptic vesicles, lambert-eaton like cms 2. synaptic defect: endplate ach esterase deficiency 3. postsyn...

BACKGROUND Mutations that disrupt the conversion of prelamin A to mature lamin A cause the rare genetic disorder Hutchinson-Gilford progeria syndrome and a group of laminopathies. Our understanding of how A-type lamins function in vivo during early vertebrate development through aging remains limited, and would benefit from a suitable experimental model. The zebrafish has proven to be a tractab...

The premature ageing Werner syndrome (WS) is characterized by the early onset of many age related phenotypes, including graying of hair, cataracts, atherosclerosis, cancer and type 2 diabetes. Type 2 diabetes (DM2) is the loss of blood glucose homeostastis, due to insulin resistance and a failure of acute glucose-stimulated insulin secretion (GSIS) by pancreatic cells. Early compensation for in...

Loss of WRN causes the genomic instability progeroid syndrome, Werner syndrome. WRN encodes a multifunctional nuclear protein with 3'-->5' exonuclease and 3'-->5' helicase activities. Linear plasmids with noncompatible ends introduced to Werner syndrome cells underwent extensive deletions at nonhomologous joining ends, particularly at the 3' protruding single-stranded end. This extensive deleti...
