*Rummler, LS; *Palispis, WA; *Truong, LN; *Chao, T; *Rowshan, K; +*Gupta, RG +*University of California Irvine, Irvine, CA [email protected] INTRODUCTION: Chronic nerve compression (CNC) injuries, such as carpal tunnel syndrome, are common orthopaedic conditions. Until recently, little has been known about the cellular and molecular changes after CNC injury. Acute nerve injuries, like axotomy and...

Collective cell migration is an essential feature both in embryonic development and cancer progression. The molecular mechanisms of these coordinated directional cell movements still need to be elucidated. The migration of cranial neural crest (CNC) cells during embryogenesis is an excellent model for collective cell migration in vivo. These highly motile and multipotent cells migrate direction...

background: this study set out to evaluate the utility of cerebrovascular virtual non-contrast (vnc) scans. materials and methods: conventional non-contrast (cnc) and dual-energy computed tomography angiography (de-cta) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...

We achieved a multiscale description of the thermal conductivity of cellulose nanocrystals (CNCs) from single CNCs (∼0.72-5.7 W m(-1) K(-1)) to their organized nanostructured films (∼0.22-0.53 W m(-1) K(-1)) using experimental evidence and molecular dynamics (MD) simulation. The ratio of the approximate phonon mean free path (∼1.7-5.3 nm) to the lateral dimension of a single CNC (∼5-20 nm) sugg...

Neural crest development involves epithelial-mesenchymal transition (EMT), during which epithelial cells are converted into individual migratory cells. Notably, the same signaling pathways regulate EMT function during both development and tumor metastasis. p53 plays multiple roles in the prevention of tumor development; however, its precise roles during embryogenesis are less clear. We have inv...

In this work, cellulose nanocrystals (CNCs) were obtained from flax fibers by an acid hydrolysis assisted by sonochemistry in order to reduce reaction times. The cavitation inducted during hydrolysis resulted in CNC with uniform shapes, and thus further pretreatments into the cellulose are not required. The obtained CNC exhibited a homogeneous morphology and high crystallinity, as well as typic...

Context Carney complex (CNC) is a syndrome characterized by hyperplasia of endocrine organs and may present with clinical features of Cushing syndrome and acromegaly due to functional adrenal and pituitary gland tumors. CNC has been linked to mutations in the regulatory subunit of protein kinase A type I-alpha (PRKAR1A) gene. Design Tissue samples were taken from the hypothalamus or thalamus ...

در این پژوهش، برای بهبود ویژگی­های کاربردی فیلم­های بر پایه نشاسته، ابتدا از میزان ثابت اسیدسیتریک و پلی­وینیل­الکل (pvoh) استفاده و پس از آن اثر سطوح مختلف غلظت دو نوع نانوذره نانوکریستال ­سلولز (cnc) و دی­اکسید­ تیتانیم (tio2) به صورت توأم و نرم­کننده گلیسرول (gly) بررسی شد.  آزمون گرماسنجی پویشی افتراقی (dsc) نشان می­دهد که افزودن cnc و tio2 به ترتیب موجب افزایش دمای ذوب و انتقال شیشه­ای و ک...
