Frontotemporal dementia (FTD) was one of the lesser known dementias until the recent advancements revealing its genetic and pathological foundation. This common neurodegenerative disorder has three clinical subtypes- behavioral, semantic and progressive non fluent aphasia. The behavioral variant mostly exhibits personality changes, while the other two(More)
In recent years the dispersion and directed assembly of nano-particles in liquid crystal media has proved an interesting field for investigation and one that may yield new hybrid materials for optical applications and fundamental research. In this paper, we investigate the dispersion of quantum dots in different liquid crystal phases, looking at aggregation(More)
BACKGROUND The risk factors predictive of intracranial aneurysm rupture remain incompletely defined. OBJECTIVE To examine the association between various nonmodifiable risk factors and aneurysm rupture in a large cohort of patients evaluated at a single institution. METHODS A retrospective analysis of patients admitted to a cerebrovascular facility(More)
Researchers have long been fascinated by wrinkles as a pervasive natural phenomenon. [1–4] Recently, there has been a resurgence of interest in emulating and leveraging wrinkles for various applications. Polymeric wrinkles are finding increased utility as complex quasiperiodic structures important in applications, including cell-fate studies. [5,6] Flexible(More)
BACKGROUND Traumatic brain injury (TBI) is a major cause of disability, morbidity, and mortality. The effect of the acute respiratory distress syndrome and acute lung injury (ARDS/ALI) on in-hospital mortality after TBI remains controversial. OBJECTIVE To determine the epidemiology of ARDS/ALI, the prevalence of risk factors, and impact on in-hospital(More)
Mild cognitive impairment (MCI) is a dynamic state between normal cognition and dementia, where interventions can be taken to stop or delay the progression to dementia. It is broadly of 2 types-amnestic, where memory loss is the chief concern and nonamnestic, where it is not. One variant of nonamnestic, dysexecutive, being more prevalent is sometimes known(More)
OBJECTIVE This study has explored the impact of Hunt-Hess (H-H) grade of aneurysmal subarachnoid hemorrhage (aSAH) on the glycemic status of such patients during their intensive care unit (ICU) stay and has also analyzed whether H-H grade predicts their outcome independent of their glycemic status. MATERIALS AND METHODS This was a retrospective case(More)
Quantum dot/liquid crystal nano-composites are promising new materials for a variety of applications in energy harvesting, displays and photonics including the liquid crystal laser. To realize many applications, however, we need to control and stabilize nano-particle dispersion in different liquid crystal host phases and understand how the particles behave(More)
The design and development of multifunctional composite materials from artificial nano-constituents is one of the most compelling current research areas. This drive to improve over nature and produce 'meta-materials' has met with some success, but results have proven limited with regards to both the demonstration of synergistic functionalities and in the(More)
Performance management is the process of creating a work environment or setting in which people are enabled to perform to the best of their abilities. It emphasizes communication and focuses on adding value to the organization by promoting improved job performance and encouraging skill development. Performance Management involves clarifying the job duties,(More)
