Anxiety disorders, such as post-traumatic stress, are more prevalent in women and are characterized by impaired inhibition of learned fear and medial prefrontal cortex (mPFC) dysfunction. Here we examined sex differences in fear extinction and mPFC activity in rats. Females showed more learned fear expression during extinction and its recall, but not fear conditioning. They also showed more spo...

Persistent social inequities in the United States demand attention to culturally responsive (CR) teaching, which requires a specific disposition toward students and teaching. Using survey data of secondary teachers ( N = 417) seven urban districts across country engaging equity-oriented professional learning (PL) initiatives, we examine relationship between teachers’ beliefs about, self-efficac...

Pulmonary lymphangiectasia (PL) is a rare condition characterized by dilatation of the lymphatic vessels. Post-neonatal PL is usually associated with pleural effusion and should therefore be suspected in the presence of chylothorax. We describe a post-neonatal manifestation of PL in a 7-year-old boy presenting chylothorax. Radiological examinations included thorax X-ray, ultrasound, and compute...

A four-year-old male neutered Australian shepherd dog was diagnosed with a thymoma and concurrent mature T cell lymphocytosis. The lymphocytosis consisted of a mixed population of T cells expressing either CD4 or CD8 or neither marker, and the result of polymerase chain reaction for antigen receptor rearrangement was negative. The peripheral lymphocytosis resolved within 24 hours following thor...

High-dose glucocorticosteroid hormones are a mainstay in the treatment of relapses in multiple sclerosis. We searched for a way to deliver ultra high doses of glucocorticosteroids to the CNS of rats with experimental autoimmune encephalomyelitis (EAE) using a novel formulation of polyethylene glycol (PEG)-coated long-circulating liposomes encapsulating prednisolone (predni solone liposomes, PL)...

The classical notion of persistency, originated in 60s, has been extensively studied up to now. An action of a processing system is said to be persistent if, whenever it becomes enabled, it remains enabled until executed. And a system is said to be persistent if each of its actions is persistent. This notion, introduced by Karp/Miller, is one of the most frequently discussed issues in the Petri...

Infection of bovines with bovine leukaemia virus (BLV) manifests itself in either of two ways: 30-70% of carriers develop persistent lymphocytosis (PL), with the viral genome integrated at a large number of different sites in the DNA of the affected B-lymphocytes, without causing any chromosomal abnormalities. Only 0,1-10% of carriers develop lymphoid tumours, which also consist of B-lymphocyte...

BACKGROUND Villous atrophy (VA) with intraepithelial lymphocytosis is the histological hallmark of coeliac disease (CD), but reported rates of mucosal recovery are variable. AIM To determine the impact of age and other demographic variables on the probability of persistent VA on follow-up biopsy. METHODS We identified patients with VA on duodenal histology at all 28 Swedish pathology depart...
