Imaging the 3D microstructural changes of ice cream during meltdown.

Ice cream is a multiphase frozen dessert that often melts during distribution and upon consumption. The meltdown phenomenon is one of the concerns in the quality preservation of ice cream for consumer convenience in the frozen food industry. In this context, X-ray tomography was used to visualise and quantify 3D ice crystal and air bubble evolution during the meltdown of ice cream.

Endoscopic resection of the calcaneonavicular coalition.

Unlabelled: Tarsal coalition has an incidence between 2-5% of the general population, and calcaneonavicular is the most frequent (53%). When conservative treatment fails, surgical resection must be indicated. Endoscopic resection is a less invasive technique and can be considered an alternative with better functional recovery.

Ankle tuberculosis. A case in childhood.

Articular tuberculosis of the ankle joint is a rare presentation of skeletal tuberculosis (10% of cases). This unusual location and the low index of clinical suspicion leads to delays in diagnosis and treatment. Radiographic and analytic studies are unspecific in the first stage.

Pectin modifications and the role of pectin-degrading enzymes during postharvest softening of Jonagold apples.

This study aimed at understanding softening in Jonagold apple (Malus×domestica Borkh.) fruits, by investigating pectin modifications and the evolution of pectin-modifying enzymes during postharvest storage and ripening. Jonagold apples were harvested at commercial maturity and stored at different temperatures and controlled atmosphere conditions for 6 months, followed by exposure to ambient shelf life conditions (20 °C under air) for 2 weeks.

A reinforced rigid fixation device for unstable intertrochanteric fractures.

A 120 degrees blade plate reinforced by a strut is introduced for the treatment of unstable intertrochanteric and proximal subtrochanteric fractures. Mechanical tests showed that the strength of this reinforced resistance device was 11,758 N. This strength is two and three times greater than that of the Gamma nail and sliding hip screw, respectively, and five times greater with the strut than without it.
