BACKGROUND Understanding the effects of capsule composition and transplantation site on graft outcomes of encapsulated islets will aid in the development of more effective strategies for islet transplantation without immunosuppression. METHODS Here, we evaluated the effects of transplanting alginate (ALG)-based microcapsules (Micro) in the confined and well-vascularized epididymal fat pad (EF...

introduction: to recognize the myelinated nerve fibers of the external capsule in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial sections in all three cardinal planes after fixation and processing. these sections were stained by klüver - barrera and heidenhain - woelcke methods. results: some fibers from different ...

purpose: to evaluate the diagnostic signs, intraoperative complications and postoperative outcomes in children with congenital cataract and pre-existing posterior capsule defect (ppcd). methods: this interventional case series was conducted on 14 eyes of 7 patients who underwent lensectomy-anterior vitrectomy for congenital cataract with ppcd. all children had bilateral cataract. preoperative d...

We fabricate and characterize capsules that are composite membranes, made of a polymer network stabilized by adsorption to colloids and inflated by osmotic pressure from internal free polyelectrolyte; here, poly-l-lysine forms the network and inflates the capsules. To assess these capsules' properties and structure, we deform capsules using microcantilevers and use finite element modeling to de...

OTT, C. E., L. G. NAVAR, AND A. C. GUYTON. Pressures in static and dynamic states from capsules implanted in the kidney. Am. J. Physiol. 22 l(2) : 394-400. 197 1 .-Renal interstitial fluid pressure was measured in 35 unanesthetized dogs from perforated capsules implanted in the kidney. Pressure measurements were made from a small catheter run from the interior of the capsule to the exterior of ...

capsules from a range of pathogenic bacteria are the key determinants of virulency. the capsule hasbeen implicated in virulence of pasteurella multocida. in this study a type-specific polymerase chain reaction(pcr) assay was used for capsular typing of 39 avian p. multocida isolates from iran. the pcr amplified afragment of 1044 bp from all of tested isolates. it was found that all avian p. mul...

The terrestrial embryos of many amphibians obtain water in two ways; in a liquid phase from the substrate on which eggs are deposited, and in a vapour phase from the surrounding atmosphere. We tested whether the mode of water flux (liquid or vapour) affected the morphology and metabolic traits of the terrestrial Victorian smooth froglet (Geocrinia victoriana) embryos by incubating eggs both wit...

Cryptococcus neoformans is a basidiomycete human fungal pathogen that causes meningoencephalitis in both immunocompromised and immunocompetent individuals. The ability to sense and respond to diverse extracellular signals is essential for the pathogen to infect and cause disease in the host. Four major stress-activated signaling (SAS) pathways have been characterized in C. neoformans, including...

Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

I was excited by the results presented in the excellent paper by Sheppard et al. showing a 2.3% increase in lens volume and a decrease of 1.82% in surface during accommodation in human volunteers. I was very gratified that they acknowledged that we had predicted similar changes in human lens volume and surface based on mathematical modeling of human lens dimensions, using the Pappus theorem as ...
