A university‐certified course on dossier assessment for regulatory scientists in Africa—Reporting on our 5‐year experience

British Journal of Clinical Pharmacology, EarlyView.
Aim The shortage of trained clinical assessors in African National Regulatory Authorities (NRAs) poses a challenge to effective regulatory decision‐making. Developed in line with the World Health Organization's (WHO) Global Competency Framework (WHO‐GCF), a university‐certified short course, Dossier assessment for clinical assessors in Africa, was ...

Ground-Control Networks for Image Based Surface Reconstruction: An Investigation of Optimum Survey Designs Using UAV Derived Imagery and Structure-from-Motion Photogrammetry

Remote Sensing, 2016
The use of small UAV (Unmanned Aerial Vehicle) and Structure-from-Motion (SfM) with Multi-View Stereopsis (MVS) for acquiring survey datasets is now commonplace, however, aspects of the SfM-MVS workflow require further validation.

MULTI-SCALE MATCHING FOR THE AUTOMATIC LOCATION OF CONTROL POINTS IN LARGE SCALE AERIAL IMAGES USING TERRESTRIAL SCENES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
A technique to automatically locate Ground Control Points (GCPs) in large aerial images is presented considering the availability of low accuracy direct georeferencing data. The approach is based on image chips of GCPs extracted from vertical terrestrial

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

Clinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

FUNCTIONAL GENOMICS IDENTIFIES TIS21-DEPENDENT MECHANISMS AND PUTATIVE CANCER DRUG TARGETS UNDERLYING MEDULLOBLASTOMA SHH-TYPE DEVELOPMENT

Frontiers in Pharmacology, 2016
We have recently generated a novel medulloblastoma (MB) mouse model with activation of the Shh pathway and lacking the MB suppressor Tis21 (Patched1+-Tis21KO).ts main phenotype is a defect of migration of the cerebellar granule precursor cells (GCPs). By

Single flap approach combined with periosteal pedicle flap as a regenerative procedure: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Single flap approach (SFA) is a validated procedure for obtaining clinical attachment gain and pocket closure when applied to deep intraosseous defects. However, the presence of an interdental crater as well as the tooth location were associated with a lower rate of primary intention closure, possibly jeopardizing the outcome of the
