P olarized cell growth is important for morphogenesis and function of specialized cell types in eukaryotes. Typical tip-growing cells in plants are root hairs and pollen tubes (Fig. 1). A root hair is a highly polarized tubular structure emerging from a special type of cell on the root surface, from which water and nutrients are absorbed and supplied to the plant body (Fig. 1A). A root hair als...

This review focuses on facial emotion recognition (FER) in individuals with attention- deficit/hyperactivity disorder (ADHD). Behavioral studies of FER in ADHD have resulted in inconsistent findings. Here, we discuss the factors that vary across studies and the way that they influence FER processes in ADHD. Across reviewed studies, fear was the most deficient facial expression to be recognized....

Quinacrine, a drug with antimalarial and anticancer activities that inhibits NF-κB and activates p53, has progressed into phase II clinical trials in cancer. To further elucidate its mechanism of action and identify pathways of drug resistance, we used an unbiased method for validation-based insertional mutagenesis to isolate a quinacrine-resistant cell line in which an inserted CMV promoter dr...

OBJECTIVES To examine the association between the fractional esterification rate of cholesterol (C) in low density lipoprotein- and very low density lipoprotein-depleted plasma (FER(HDL)) and coronary artery disease (CAD) and the influence of serum HDL-C levels. BACKGROUND The function of HDL in reverse cholesterol transport is involved in the antiatherogenic action of HDL, and FER(HDL) is a ...

Facial emotion recognition (FER) is an important topic in the fields of computer vision and artificial intelligence owing to its significant academic and commercial potential. Although FER can be conducted using multiple sensors, this review focuses on studies that exclusively use facial images, because visual expressions are one of the main information channels in interpersonal communication. ...

Neutrophil recruitment and directional movement toward chemotactic stimuli are important processes in innate immune responses. This study examines the role of Fer kinase in neutrophil recruitment and chemotaxis to various chemoattractants in vitro and in vivo. Mice targeted with a kinase-inactivating mutation (Fer(DR/DR)) or wild type (WT) were studied using time-lapse intravital microscopy to ...

Androgen withdrawal is the most effective form of systemic therapy for men with advanced prostate cancer. Unfortunately, androgen-independent progression is inevitable, and the development of hormone-refractory disease and death occurs within 2 to 3 years in most men. The understanding of molecular mechanisms promoting the growth of androgen-independent prostate cancer cells is essential for th...

Iron deficiency is among the most common nutritional disorders in plants. To cope with low iron supply, plants with the exception of the Gramineae increase the solubility and uptake of iron by inducing physiological and developmental alterations including iron reduction, soil acidification, Fe(II) transport and root-hair proliferation (strategy I). The chlorotic tomato fer mutant fails to activ...

The present investigation explores the relationship between facial emotion recognition (FER) and symptom domains in three groups of schizophrenia spectrum patients (43 ultra-high-risk, 50 first episode and 44 multi-episode patients) in which the existence of FER impairment has already been demonstrated. Regression analysis showed that symptoms and FER impairment are related in multi-episode pat...

Facial expression recognition (FER) is a crucial technology and a challenging task for human–computer interaction. Previous methods have been using different feature descriptors for FER and there is a lack of comparison study. In this paper, we aim to identify the best features descriptor for FER by empirically evaluating five feature descriptors, namely Gabor, Haar, Local Binary Pattern (LBP),...
