The identification of the genes necessary for human T-cell leukemia virus (HTLV-1) persistence in humans may provide targets for therapeutic approaches. We demonstrate that ablation of the HTLV-1 genes encoding p12, p30, or the HBZ protein, does not affect viral infectivity in rabbits and in this species, only the absence of HBZ is associated with a consistent reduction in virus levels. We obse...

Prolonged early-life seizures are associated with disruptions of affective and cognitive function. Postictal disturbances, temporary functional deficits that persist for hours to days after seizures, have not yet been thoroughly characterized. Here, we used kainic acid (KA) to induce status epilepticus (SE) in immature rats at three developmental stages (postnatal day (P) 15, 21, or 30) and sub...

BACKGROUND/AIMS Glucocorticoid receptors (GR) mediate cellular processes which may be neuroprotective and/or neurotoxic to the neonatal rat brain. Our aim was to describe GR ontogeny in the developing rat brain cortex and changes in GR expression after permanent neonatal focal cerebral ischemia (FCI). METHODS GR Western blots and immunohistochemical stains were performed on neonatal rat corti...

Considering the importance of a deeper understanding of the effect throughout life of opioid analgesia at birth, our objective was to determine whether morphine administration in early life, once a day for 7 days in 8-day-old rats, alters the nociceptive response over the short (P16), medium (P30), and long term (P60) and to evaluate which system is involved in the altered nociceptive response....

All-trans retinoic acid (ATRA) is one of the first line agents in differentiation therapy for acute promyelocytic leukemia (APL). However, drug resistance is a major problem influencing the efficacy of ATRA. Identification of mechanisms of ATRA resistance are urgenly needed. In the present study, we found that expression of C/EBPα, an important transcription factor for myeloid differentiation, ...

Problem Due to the increase in prevalence and burden of allergic disease, demand for specialist hospital allergy services is significant, 1 has given rise two main problems. Firstly, increased long waiting times new follow-up appointments secondly patient safety being compromised. 2 Aim By December 2019, firstly reduce outpatient clinic time by 60% those patients referred pharmacist an eczema r...

Mesenchymal stem cells (MSC) derived from bone marrow stem cells (BMSC) and adipose tissue stem cells (ASC) of humans and rhesus macaques were evaluated for their cell cycle properties during protracted culture in vitro. Human ASCs (hASC) and rhesus BMSCs (rBMSC) underwent significantly more total population doublings than human BMSCs (hBMSC) and rhesus ASCs (rASC). The cell cycle profile of al...

-The level of Gross cell-surface antigen (GCSAa) expression at the surface of murine retrovirus-infected fibroblasts was determined by quantitative absorption of the anti-GCSAa activity of a serum produced in syngeneic W/Fu rats immunized against (C58NT)D lymphoma, and tested in a cytotoxicity assay against ESG2 lymphoma cells. While GCSAa was specifically expressed on Gross-type virus (G-MuLV)...

Canine monocytic ehrlichiosis (CME) is a common tick-borne disease caused by the rickettsial bacterium Ehrlichia canis (Rickettsiales: Anaplasmataceae). In view of the different stages and variable clinical signs of CME, which can overlap with those of other infections, a conclusive diagnosis can more readily be obtained by combining clinical and hematological evaluations with molecular diagnos...
