Factors Contributing to Malnutrition among Children Under 5 Years at St. Elizabeth Catholic Hospital, Ahafo Hwidiem.

Background: Nutrition among children under 5 plays an important role in the overall development of children physically and psychologically. Nutritional deficiencies and malnutrition generally affect children. In this study, we estimate the prevalence of 3 malnutrition indicators underweight, stunting and wasting and to assess factors associated with them.

Precise measurements of chromatin diffusion dynamics by modeling using Gaussian processes.

The spatiotemporal organization of chromatin influences many nuclear processes: from chromosome segregation to transcriptional regulation. To get a deeper understanding of these processes, it is essential to go beyond static viewpoints of chromosome structures, to accurately characterize chromatin's diffusion properties. We present GP-FBM: a computational framework based on Gaussian processes and fractional Brownian motion to extract diffusion properties from stochastic trajectories of labeled chromatin loci.

A Brn2-Zic1 axis specifies the neuronal fate of retinoic-acid-treated embryonic stem cells.

Mouse embryonic stem cells (ESCs) treated with all-trans retinoic acid differentiate into a homogenous population of glutamatergic neurons. Although differentiation is initiated through activation of target genes by the retinoic acid receptors, the downstream transcription factors specifying neuronal fate are less well characterised. Here, we show that the transcription factor Brn2 (also known as Pou3f2) is essential for the neuronal differentiation programme.

Single-cell gene expression signatures reveal melanoma cell heterogeneity.

It is well established that tumours are not homogenous, but comprise cells with differing invasive, proliferative and tumour-initiating potential. A major challenge in cancer research is therefore to develop methods to characterize cell heterogeneity. In melanoma, proliferative and invasive cells are characterized by distinct gene expression profiles and accumulating evidence suggests that cells can alternate between these states through a process called phenotype switching.
