Superstable lipid vacuoles endow cartilage with its shape and biomechanics.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Periacetabular osteotomy for containment of the nonarthritic dysplastic hip secondary to poliomyelitis.

Background: Poliomyelitis results in a flaccid paralysis of muscles that can lead to hip instability. The objective of this study was to determine the results of the Bernese periacetabular osteotomy in patients with paralytic hips secondary to poliomyelitis.

Methods: Nine patients who had a Bernese periacetabular osteotomy were identified as having paralytic hip dysplasia secondary to poliomyelitis.

Persistent vaginal hemorrhage caused by vaginal vascular ectasia in a dog.

Case Description: A 6-year-old 36.5-kg (80.3-lb) spayed female Labrador Retriever was evaluated because of an 11-month history of vaginal bleeding.

Osteochondritis dissecans-like lesion of the intercondylar fossa of the femur in a dog.

An 11-month-old neutered female crossbreed dog was admitted with left pelvic limb lameness. Radiographs and computed tomography identified an osteochondritis dissecans- (OCD) like lesion in the intercondylar fossa of the femur originating from the axial aspect of the medial femoral condyle. Stifle arthrotomy was performed in order to remove the bony fragment.

Rostral cerebellar arterial infarct in two cats.

A 10-year-old female neutered domestic shorthair (DSH) cat and a 6-year-old female neutered Siamese cat were presented following a peracute onset of decerebellate rigidity and a cerebellar vestibular syndrome, respectively. In both cats, physical examination and routine blood tests were unremarkable, as was routine analysis of cerebrospinal fluid obtained from the DSH cat. Based on the magnetic resonance imaging (MRI) features - focal wedge-shaped lesion in the cerebellum characterised by hyperintensity in T2-weighted, T2( *)-gradient echo and fluid attenuated inversion recovery (FLAIR) images - a presumptive diagnosis of cerebellar infarct was made in both cases.
