The international empirics of management.

A country's national income broadly depends on the quantity and quality of workers and capital. But how well these factors are managed within and between firms may be a key determinant of a country's productivity and its GDP. Although social scientists have long studied the role of management practices in shaping business performance, their primary tool has been individual case studies.

Measuring business-level expectations and uncertainty: survey evidence and the COVID-19 pandemic.

Utilizing a unique firm-level survey in Japan that contains five-bin forecasts for sales, we document three findings. First, firm-level subjective uncertainty is highly and positively related to volatility of past firm growth. Second, there are substantial variations in subjective uncertainty across firms, with a long right tail with extremely high subjective uncertainty.

Filopodia play an important role in the trans-mesothelial migration of ovarian cancer cells.

Ovarian cancer cells shed from primary tumors can spread easily to the peritoneum via the peritoneal fluid. To allow further metastasis, the cancer cells must interact with the mesothelial cell layer, which covers the entire surface of the peritoneal organs. Although the clinical importance of this interaction between cancer and mesothelial cells has been increasingly recognized, the molecular mechanisms utilized by cancer cells to adhere to and migrate through the mesothelial cell layer are poorly understood.

A New Serum Biomarker Set to Detect Mild Cognitive Impairment and Alzheimer's Disease by Peptidome Technology.

Background: Because dementia is an emerging problem in the world, biochemical markers of cerebrospinal fluid (CSF) and radio-isotopic analyses are helpful for diagnosing Alzheimer's disease (AD). Although blood sample is more feasible and plausible than CSF or radiological biomarkers for screening potential AD, measurements of serum amyloid- β (Aβ), plasma tau, and serum antibodies for Aβ1 - 42 are not yet well established.

Objective: We aimed to identify a new serum biomarker to detect mild cognitive impairment (MCI) and AD in comparison to cognitively healthy control by a new peptidome technology.

Seasonal regulation of the lncRNA LDAIR modulates self-protective behaviours during the breeding season.

To cope with seasonal environmental changes, animals adapt their physiology and behaviour in response to photoperiod. However, the molecular mechanisms underlying these adaptive changes are not completely understood. Here, using genome-wide expression analysis, we show that an uncharacterized long noncoding RNA (lncRNA), LDAIR, is strongly regulated by photoperiod in Japanese medaka fish (Oryzias latipes).
