A Rare Case of Acute Calcium Pyrophosphate Deposition Disease Following Zoledronic Acid Infusion.

Calcium pyrophosphate deposition (CPPD) disease of the joints is a form of arthritis that can present in a severely debilitating form of pseudogout. Although mostly idiopathic, pseudogout has been reported following bisphosphonate therapy in only nine cases to date with a pathophysiology that remains unclear. We present the case of a 59-year-old postmenopausal woman who developed the rare onset of acute polyarticular CPPD disease following zoledronic acid infusion for the treatment of osteoporosis.

The ENU-3 protein family members function in the Wnt pathway parallel to UNC-6/Netrin to promote motor neuron axon outgrowth in C. elegans.

The axons of the DA and DB classes of motor neurons fail to reach the dorsal cord in the absence of the guidance cue UNC-6/Netrin or its receptor UNC-5 in C. elegans. However, the axonal processes usually exit their cell bodies in the ventral cord in the absence of both molecules.

Estimating the harms and costs of cannabis-attributable collisions in the Canadian provinces.

Introduction: In 2012, 10% of Canadians used cannabis and just under half of those who use cannabis were estimated to have driven under the influence of cannabis. Substantial evidence has accumulated to indicate that driving after cannabis use increases collision risk significantly; however, little is known about the extent and costs associated with cannabis-related traffic collisions. This study quantifies the costs of cannabis-related traffic collisions in the Canadian provinces.

ENU-3 functions in an UNC-6/netrin dependent pathway parallel to UNC-40/DCC/frazzled for outgrowth and guidance of the touch receptor neurons in C. elegans.

Background: UNC-6 and SLT-1 guide the migrations of the ventrally directed processes of the AVM and PVM touch receptor neurons and UNC-6 guides the axons of the DA and DB classes of motor neurons in C. elegans. The UNC-6 receptors are UNC-5 and UNC-40.
