The diagnostic value of dopamine transporter imaging and olfactory testing in patients with parkinsonian syndromes

The aim of the study was to compare the efficacy of olfactory testing and presynaptic dopamine imaging in diagnosing Parkinson's disease (PD) and atypical parkinsonian syndromes (APS); to evaluate if the combination of these two diagnostic tools can improve their diagnostic value. A prospective investigation of 24 PD patients, 16 APS patients and 15 patients with non-parkinsonian syndromes was per

Comparison between visual assessment of dopaminergic degeneration pattern and semi-quantitative ratio calculations in patients with Parkinson's disease and Atypical Parkinsonian syndromes using DaTSCAN® SPECT

OBJECTIVE: To verify if (123)I-FP-CIT, DaTSCAN(®) can differentiate early stages of Parkinson's disease (PD) as well as patients with Atypical Parkinsonian syndromes (APS) from manifest Parkinson's disease.METHODS: 128 consecutive patients were investigated with (123)I-FP-CIT SPECT during a 4-year period. All patients were diagnosed according to the established consensus criteria for diagnosis of

How to optimize high-order harmonic generation in gases

High-order harmonic generation (HHG) in gases leads to short-pulse extreme ultraviolet (XUV) radiation that is useful in a number of applications, such as attosecond science and nanoscale imaging. However, this process depends on many parameters, and there is still no consensus on how to choose the target geometry to optimize the source efficiency. We review the physics of HHG with emphasis on the

Cultural Adaptation of Interventions and the a Priori Assessment of Intervention Fit : Exploring Measurement Invariance for American and Swedish Youth Leaving Care

Purpose: There is a growing literature on the importance of cultural adaptation of research-supported social work interventions. Few studies have however offered systematic methods for the a priori assessment of intervention fit in a new context. The current study explores the use of measurement invariance analyses to help identify whether key theoretical constructs in an intervention’s theory of

Olfactory disorders and consequences

Generally, three functions are assigned to the sense of smell, namely warning of potential danger, social communication, and importance for eating and drinking. These functions are also reflected in some of the complaints of patients with smell disorders: occurrence of household accidents, inability to smell other people like family members, loss of flavor perception. Still, approximately 5% of th

Transformative innovation policy–lessons from the innovation system literature

This paper criticizes attempts to present narrow perspectives on innovation policy as reflecting the use of the concept innovation system. While it is correct that innovation policy, at least until recently, has given higher priority to economic growth than to global challenges such as climate change and income inequality this is in no way immanent in the innovation system concept. To illustrate,

RNA sequencing-based single sample predictors of molecular subtype and risk of recurrence for clinical assessment of early-stage breast cancer

BackgroundMultigene expression assays for molecular subtypes and biomarkers can aid clinical management of early invasive breast cancer. Based on RNA-sequencing we aimed to develop single-sample predictor (SSP) models for conventional clinical markers, molecular intrinsic subtype and risk of recurrence (ROR).MethodsA uniformly accrued breast cancer cohort of 7743 patients with RNA-sequencing data

Consumer Trust and Platformised Retail Personalisation

As retail is becoming increasingly digitised in its operation and consumer relationships, much faith is put into automation, prediction and insights drawn from consumer data to shape consumer experiences and expectations. Under the umbrella of data-collection and artificial intelligence (AI), this chapter studies the role of consumer trust in retail personalisation. We draw empirical insights from

Govindjee’s 90th birthday : a life dedicated to photosynthesis

We celebrate Govindjee, Professor Emeritus of Plant Biology, Biochemistry, and Biophysics, University of Illinois at Urbana-Champaign, on the occasion of his 90th birthday. He is renowned for his pioneering work in the discovery of the two-light reactions and two photosystems, PSI and PSII, leading to the Z-scheme of the electron transport chain; and for breakthrough advances in oxygenic photosynt

Enhanced Temperature Stratification with Deflectors Laid within the Horizontal Water Storage Tank

In the passive solar water heater, temperature stratification is a valuable thermodynamic parameter for horizontal water storage tanks. This investigation aims to optimize the deflector and numerically study the effects of various deflector lengths and materials on temperature stratification of a horizontal water storage tank during natural convection. Firstly, comparative thermal performances of

Upper airway microbiome transplantation for patients with chronic rhinosinusitis

Background: Chronic or recurrent rhinosinusitis without polyps (CRSsNP) is characterized by a persistent inflammation of the sinonasal mucosa. The underlying cause is unclear but increasing interest has been directed toward changes in the sinonasal microbiome as a potential driver. Methods: Twenty-two patients diagnosed with CRSsNP were treated with antibiotics for 13 days, followed by 5 consecuti

Should Benzodiazepines be Used for Reducing Dyspnea in Patients with Advanced Illnesses?

Dyspnea is a common and highly distressing symptom in patients with advanced illnesses. Many patients continue to experience chronic dyspnea despite optimal management of underlying disease(s) and various non-pharmacologic interventions, necessitating the consideration of pharmacologic therapies for palliation of dyspnea. One commonly asked question by clinicians is whether benzodiazepines have a
