Micro‐community cytometry: sensing changes in cell health and glycoconjugate expression by imaging and flow cytometry
Summary Discerning the extent of biologically relevant heterogeneity presents unique challenges to both microscopy and flow cytometry. Micro‐environmental influences and stochastic changes in cellular behaviour can act to mask the origins of both progression and therapeutic resistance in tumour cell systems. In part the dimensionality of different and frequently metastable states can be assessed by multi‐parameter flow cytometry with unparalleled statistical robustness. Complementary application of imaging can provide valuable insights into the complex temporal changes that can occur in cell micro‐communities either ...

Implementing genomic medicine in pathology.
Abstract The finished sequence of the Human Genome Project, published 50 years after Watson and Crick's seminal paper on the structure of DNA, pushed human genetics into the public eye and ushered in the genomic era. A significant, if overlooked, aspect of the race to complete the genome was the technology that propelled scientists to the finish line. DNA sequencing technologies have become more standardized, automated, and capable of higher throughput. This technology has continued to grow at an astounding rate in the decade since the Human Genome Project was completed. Today, massively parallel sequencing, or nex...

Seroprevalence of Seasonal and Pandemic Influenza A in Kuala Lumpur, Malaysia in 2008–2010
Abstract Relatively little is known about the burden of influenza in tropical countries. The seroprevalence of pandemic influenza A (H1N1) 2009, seasonal H1N1 and H3N2 was determined in Kuala Lumpur, Malaysia. Pre‐ and post‐pandemic residual laboratory sera were tested by hemagglutination‐inhibition. The seroprevalence of A(H1N1)pdm09 increased from 3.7% pre‐pandemic to 21.9% post‐pandemic, giving an overall cumulative incidence of 18.1% (95% CI, 13.8–22.5%), mainly due to increases in those <5, 5–17, and 18–29 years old.

Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
Summary Wood cell walls fluoresce as a result of UV and visible light excitation due to the presence of lignin. Fluorescence spectroscopy has revealed characteristic spectral differences in various wood types, notably normal and compression wood. In order to extend this method of characterising cell walls we examined the fluorescence lifetime of wood cell walls using TCSPC (Time‐Correlated Single Photon Counting) as a method of potentially detecting differences in lignin composition and measuring the molecular environment within cell walls. The fluorescence decay curves of both normal and compression wood from pine conta...

The Effect of Low‐ versus High‐Variance in Product Reviews on Product Evaluation
ABSTRACT This research investigates whether the effect of low‐ versus high‐variance product reviews on the evaluation of a product about which consumers have favorable or unfavorable prior expectation can vary depending on product type, the argument quality of product reviews, and the number of reviewers. The data across three laboratory experiments demonstrate that high‐variance product reviews are more likely than low‐variance product reviews to undermine product evaluation when consumers have unfavorable prior expectation about a product. When consumers have favorable prior expectation, however, high‐variance ...

Detection of B‐Cell populations with monotypic light chain expression in cerebrospinal fluid specimens from patients with multiple sclerosis by Polychromatic Flow Cytometry
Conclusions: We conclude that the detection of a B‐cell population with monotypic light chain expression in CSF by polychromatic flow cytometry is not diagnostic of occult leptomeningeal involvement by a B‐cell non‐Hodgkin lymphoma. Moreover, these findings suggest that monotypic B‐cell populations detectable by polychromatic flow cytometry may be prevalent in patients with multiple sclerosis, and highlight the importance of clinicopathologic correlation in this application of polychromatic flow cytometry. © 2013 Clinical Cytometry Society (Source: Cytometry Part B: Clinical Cytometry)

Toddler inhibited temperament, maternal cortisol reactivity and embarrassment, and intrusive parenting.
The relevance of parenting behavior to toddlers’ development necessitates a better understanding of the influences on parents during parent–child interactions. Toddlers’ inhibited temperament may relate to parenting behaviors, such as intrusiveness, that predict outcomes later in childhood. The conditions under which inhibited temperament relates to intrusiveness, however, remain understudied. A multimethod approach would acknowledge that several levels of processes determine mothers’ experiences during situations in which they witness their toddlers interacting with novelty. As such, the current study examined mat...

Dieting and the self-control of eating in everyday environments: An experience sampling study.
CONCLUSIONS: Dietary restraint was unrelated to desire frequency and strength, but associated with higher conflict experiences and motivation to use self-control with regard to food desires. Most importantly, relationships between dietary restraint and resistance, enactment of desire, and long-term weight change were moderated by inhibitory control: Compared with dieters low in response inhibition, dieters high in response inhibition were more likely to attempt to resist food desires, not consume desired food (especially unhealthy food), and objectively lost more weight over the ensuing 4 months. These results highlight t...

Paediatric autoimmune encephalopathies: clinical features, laboratory investigations and outcomes in patients with or without antibodies to known central nervous system autoantigens
Conclusions Our study outlines the common clinical and paraclinical features of children and adolescents with probable autoimmune encephalopathies. These patients, irrespective of positivity for the known antibody targets, appeared to benefit from immunotherapies and further antibody targets may be defined in the future.
