Pathogenesis of Anterior Knee Pain in the Active Young: Is There a Relation Between the Presence of Patellofemoral Malalignment and Pain?

2012

This chapter is not intended to advocate for a particular surgical technique, but it does provide insight into improving our understanding of the pathophysiology of anterior knee pain syndrome. Our objectives were: to identify a relationship, or lack of one, between the presence of PFM and the presence of anterior knee pain; to analyze the long-term response of VMO muscle fibers to increased resting length; and to determine the incidence of patellofemoral osteoarthritis after IPR surgery. Our findings indicate (1) that not all PFM knees show symptoms; that is, PFM is not a sufficient condition for the onset of symptoms, at least in postoperative patients; (2) that the advancement of VMO has…

Identification, ecology and use blood meals from hematophagous Diptera (Glossinidae, Stomoxys and Tabanidae) for noninvasive sampling of wildlife in …

2015

The contact between human and wild fauna has considerably increased during these last decades due to the increase of human population size but also to conservation policies. As a consequence, the number of zoonotic diseases soared with a mean of six new infectious diseases per year, 75% of whom being vectorially transmitted. The way to avoid the human contamination by these emergent diseases is based on the efficient vector control resulting from a deep knowledge of the ecology and the feeding behavior of the different vector species. During our work, we have identified and characterized the ecology of 6 tsetse species (Glossina palpalis palpalis, G. fuscipes fuscipes, G. fusca congolense, …

G2019S Variation in LRRK2: An Ideal Model for the Study of Parkinson's Disease?

2019

Parkinson’s disease (PD) is the second most common neurodegenerative disorder and has plagued humans for more than 200 years. The etiology and detailed pathogenesis of PD is unclear, but is currently believed to be the result of the interaction between genetic and environmental factors. Studies have found that PD patients with the LRRK2:G2019S variation have the typical clinical manifestations of PD, which may be familial or sporadic, and have age-dependent pathogenic characteristics. Therefore, the LRRK2:G2019S variation may be an ideal model to study the interaction of multiple factors such as genetic, environmental and natural aging factors in PD in the future. This article reviewed the …

Drosophila Models of Parkinson's Disease: Discovering Relevant Pathways and Novel Therapeutic Strategies

2010

Parkinson's disease (PD) is the second most common neurodegenerative disorder and is mainly characterized by the selective and progressive loss of dopaminergic neurons, accompanied by locomotor defects. Although most PD cases are sporadic, several genes are associated with rare familial forms of the disease. Analyses of their function have provided important insights into the disease process, demonstrating that three types of cellular defects are mainly involved in the formation and/or progression of PD: abnormal protein aggregation, oxidative damage, and mitochondrial dysfunction. These studies have been mainly performed in PD models created in mice, fruit flies, and worms. Among them, Dro…

Imaging in Prune Belly Syndrome and Other Syndromes Affecting the Urogenital Tract

2018

The absence of the abdominal musculature, urinary tract dilatation, and bilateral undescended testis is known as prune belly syndrome (PBS) (Eagle and Barrett 1950; Greskovich and Nyberg 1988; Williams 1982). The classical syndrome is also known as triad syndrome, Eagle-Barrett syndrome, or abdominal muscular deficiency syndrome. There is a broad spectrum of malformations with severe dilatation of the urinary tract as a consequence of aplasia of the musculature. The pathogenetic mechanism is different from that of dilatation as a consequence of supra- or infravesical obstruction. Some patients with prune belly syndrome have a real obstruction, such as urethral aplasia with oligohydramnios s…
