OS. Examination revealed enlargement of the epithelial defect, with 50% stromal thinning nasally and inferonasally, without an apparent infiltrate (Figure 2). Corneal culture was positive for Corynebacterium pseudodiptheriticum in the enrichment broth only. A course of fortified antibiotic agents did not improve the clinical findings; there was further thinning of the stroma and impending perfo...

Gastrointestinal stromal tumors (GISTs) in adolescence are far less common than adult GISTs and have varied GIST genotypes that present diagnostic and therapeutic challenges. Here, we discuss a 21-year-old male with diagnosis of unresectable, imatinib-resistant GIST. At initial evaluation, a neoadjuvant treatment approach was recommended. As such, the patient received imatinib over the course o...

In plants, chloroplast division is an integral part of development, and these vital organelles arise by binary fission from pre-existing cytosolic plastids. Chloroplasts arose by endosymbiosis and although they have retained elements of the bacterial cell division machinery to execute plastid division, they have evolved to require two functionally distinct forms of the FtsZ protein and have los...

the endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. they are rare neoplasms, diagnosed in most instances by microscopy. although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in end...

background: despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow mesenchymal stem cells (mscs) has remained to be challenged. in this study successful isolation, multilineage differentiation, and proliferation potentials of sheep mscs derived from bone marrow, adipose tissue, and liver were widely investigate...
