Insufficient drug tolerance presents a major challenge in the development of neutralizing antibody (NAb) assays for biotherapeutics. Sample pre-treatment using solid-phase extraction with acid dissociation (SPEAD) is widely reported to improve drug tolerance. In this paper, a case study is presented in which SPEAD was used in conjunction with a competitive ligand binding NAb assay format.

Purpose: The purpose of this paper is to present simulation modelling to reconfigure a 700-bed Hong Kong hospital's master surgery schedule (MSS), aiming to improve patient flow, capacity management and resource allocation through levelling bed occupancy within the hospital.
Design/methodology/approach: A discrete-event simulation model was developed to understand how changes to the MSS would affect bed occupancy, thereby providing business intelligence for short- and long-term hospital planning. A decision tool was subsequently developed for hospital managers to test different scenarios.
Following the achievement of deep molecular response on tyrosine kinase inhibitors (TKIs), approximately half of patients with chronic myeloid leukemia (CML) can discontinue TKI and remain in treatment-free remission (TFR). The ALLG CML8 study enrolled 40 imatinib-treated patients with undetectable BCR-ABL1 mRNA (approximately MR). Molecular relapse was defined as detectable BCR-ABL1 on two consecutive tests or any single value >0.

A 1-year longitudinal study was conducted to examine the effects of retirement resources on the physical and psychological well-being of Hong Kong Chinese retirees during the transition to retirement. This study consisted of two assessments: Time 1 was conducted 6 months before retirement, while Time 2 was implemented 6 months after retirement. Personal resources and physical and psychological well-being were measured in the two assessments.
View Article and Find Full Text PDFAffective experiences at work are a key contributing factor to long-term job-related well-being and effectiveness, yet may systematically change as workers get older. Given the central role of affect in work settings, it is important to obtain a thorough understanding of older workers' strengths and vulnerabilities in affective functioning. This paper's goal was to comprehensively study age differences in mean levels and dynamics of affect (affect stability, occurrence of positive and negative daily work events, and affective reactivity) and to link these with perceptions of global occupational well-being and effectiveness.

As hepatic steatosis occurs prior to steatohepatitis and other late stage liver conditions, the distribution pattern of hepatic fat and iron concentration should be investigated to prevent sampling variability. The first purpose of this study was to perform comparison and validation of in-house hepatic fat measurements using water-fat MRI and MRS.

Organophosphorus (OP) compounds, including pesticides and chemical warfare nerve agents (CWNA), are threats to the general population as possible weapons of terrorism or by accidental exposure whether through inadvertent release from manufacturing facilities or during transport. To mitigate the toxicities posed by these threats, a therapeutic regimen that is quick-acting and efficacious against a broad spectrum of OPs is highly desired. The work described herein sought to assess the protective ratio (PR), median effective doses (ED), and therapeutic index (TI = oxime 24-h LD/oxime ED) of MMB4 DMS, HLö-7 DMS, and 2-PAM Cl against the OPs sarin (GB), VX, and phorate-oxon (PHO).
View Article and Find Full Text PDFTypical responses in muscle following acute aerobic exercise have been well documented, but the responses in brain have remained relatively unexplored. Recent reports suggest that a single bout of aerobic exercise can prime motor regions of the human brain to experience use-dependent plasticity, however, the mechanisms underlying this priming phenomenon are unclear. As a result, we asked whether a graded test to exhaustion (GXT), the most widely employed test to examine relationships between exercise and integrated responses within the musculoskeletal, cardiopulmonary, and neuropsychological systems, would be able to upregulate the expression of plasticity-related proteins in sensorimotor cortex in rats.

Current hashing methods being trained using a given static database may not be suitable for nonstationary semantic image retrieval problems. Moreover, directly retraining a whole hash table to update knowledge coming from new arriving image data may not be efficient.

We predicted that cultural differences in ideal affect-the states that people value and ideally want to feel-are reflected in: (a) how individuals present themselves when applying for a job, and (b) what individuals look for when hiring someone for a job. In Studies 1-2 ( = 236, = 174), European Americans wanted to convey high arousal positive states (HAP; excitement) more and low arousal positive states (LAP; calm) less than did Hong Kong Chinese when applying for a job. European Americans also used more HAP words in their applications and showed more "high intensity" smiles in their video introductions than did Hong Kong Chinese.

We predicted that the more people valued and ideally wanted to feel excitement and other high arousal positive states (HAP), the more affiliative (extraverted, agreeable) they would judge excited (vs. calm) faces.

This viewpoint paper argues that policy interventions can benefit from the continued use of social media analytics, which can serve as an important complement to traditional social science data collection and analysis. Efforts to improve well-being should provide an opportunity to explore these areas more deeply, and encourage the efforts of those conducting national and local data collection on health to incorporate more of these emerging data sources. Social media remains a relatively untapped source of information to catalyze policy action and social change.

Background: Some patients receiving a tyrosine kinase inhibitor (TKI) for the first-line treatment of chronic phase chronic myeloid leukemia (CML-CP) experience intolerable adverse events. Management strategies include dose adjustments, interrupting or discontinuing therapy, or switching to an alternative TKI.
Methods: This multicenter, single-arm, Phase IIIb study included CML-CP patients intolerant of, but responsive to, first-line treatment with imatinib or dasatinib.
Unlabelled: Phorate is a highly toxic agricultural pesticide currently in use throughout the world. Like many other organophosphorus (OP) pesticides, the primary mechanism of the acute toxicity of phorate is acetylcholinesterase (AChE) inhibition mediated by its bioactivated oxon metabolite. AChE reactivation is a critical aspect in the treatment of acute OP intoxication.
