The distinct properties of allo-reactive T-cell repertoires are not well understood. To investigate whether auto-reactive and encoded properties, we used dextramer enumeration, enrichment, single-cell receptor (TCR) sequencing multiparameter analysis. We found T-cells differed in mean ex vivo frequency which was antigen dependent. Allo-reactive showed clear differences TCR architecture, with en...

These experiments examined the effects of pre-test intra dorsal hippocampus (intra-CA1) administration of GABAA receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. Male NMRI mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received IP injections of either saline (10 mL/kg...

Breast cancer screening facilitates the early detection of breast cancer, although a significant number of tumors still arise in the interval between screening. The objective of this study was to measure the expression of five markers of proven prognostic significance in symptomatic breast cancer (estrogen receptor, progesterone receptor, p53, Ki67, and c-erbB2) in screen-detected and interval ...

Human epidermal growth factor receptor 2 (HER2) is a member of the epidermal growth factor receptor family having tyrosine kinase activity. Dimerization of the receptor results in the autophosphorylation of tyrosine residues within the cytoplasmic domain of the receptors and initiates a variety of signaling pathways leading to cell proliferation and tumorigenesis. Amplification or overexpressio...

Abstract Background 20-30% of breast cancer patients develop brain metastases (BM) and 5% leptomeningeal (LM). Incidence BM and/or LM is dependent on subtype. Treatment consists local treatment (resection radiotherapy) if possible systemic therapy. can be treated with radiotherapy the symptomatic location nervous system Capecitabin effective for both HER2-positive cancer. The effect capecitabin...

background : triple-negative breast cancers (tnbc) are defined as breast cancers with lack of estrogen and progesterone receptors and no overexpression of human epidermal growth factor receptor 2 (her2). this study was performed to determine the frequency and pathologic features of tnbc in iranian patients. subjects and methods: this cross-sectional study was performed on patients with breast c...

adenosine has many of the characteristics of a regulator of cerebral blood flow and adenosine receptors change in morphine dependency. in this study the changes in adenosine receptors' responsiveness of pial vessels in the hind limb area of the sensory cortex were evaluated in morphine dependent rats (mdr) using the laser doppler flowmetry technique. adult male sprague dawley rats (250-350...
