Background: Kidney disease is a rare manifestation of ankylosing spondylitis (AS) and its pathological alterations remain poorly described. The aim of this study was to investigate the clinical presentation and pathological alterations on kidney biopsy of AS patients and review and discuss the current literature on the issue. Methods: We retrospectively studied the clinical presentation and kidney pathological ...
The size and shape of organs is tightly controlled to achieve optimal function. Natural morphological variations often represent functional adaptations to an ever-changing environment. For instance, variation in head morphology is pervasive in insects and the underlying molecular basis is starting to be revealed in the Drosophila genus for species of the melanogaster group. However, it remains unclear whether s...
How to preserve a set of paintings made with European materials and taken to South Asia in the 16th century? A set of seven paintings belonging to the first altarpiece of Goa Cathedral now remain in its sacristy. Art history states that these paintings, assigned to the painter Garcia Fernandes, were produced in Lisbon circa 1530 and carried to Goa shortly after, Serrão (2011), Reis-Santos (1957).

In Drosophila, large variations in rearrangement rate have been reported among different lineages and among Muller’s elements. Nevertheless, the mechanisms that are involved in the generation of inversions, their increase in frequency, as well as their impact on the genome are not completely understood. This is in part due to the lack of comparative studies on species distantly related to Drosophila melanogaste...
