BACKGROUND: As the demand for monoclonal antibodies (mAb) increases, more efficient expression methods are required for their manufacturing process. Transcriptional gene silencing is a common phenomenon in recombinant cell lines which leads to expression reduction and instability. There are reports on improved antibody expression in ubiquitous chromatin opening element (UCOE) containing both heavy and light chain gene constructs. Here we investigate the impact of having these elements as part of the light chain, heavy chain or both genes during cell line development...

The classification of cutaneous lymphomas is multidisciplinary and requires the correlation between clinical, histopathological, immunohistochemical, and molecular diagnostic elements. In this article, we present four different cases of CD30-positive T-cell lymphoma with cutaneous manifestations. We compare cases with definitive diagnosis of papulosis lymphomatoid type C, primary cutaneous anaplastic large T-cell lymphoma, systemic anaplastic large T-cell lymphoma with secondary skin involvement, and mycosis fungoides with large cell transformation, highlighting the importance of clinicopathological correlation to classify these cases...

Several gallium-based liquid metal alloys are liquid at room temperature. As 'liquid', such alloys have a low viscosity and a high surface tension while as 'metal', they have high thermal and electrical conductivities, similar to mercury. However, unlike mercury, these liquid metal alloys have low toxicity and a negligible vapor pressure, rendering them much safer. In comparison to mercury, the distinguishing feature of these alloys is the rapid formation of a self-limiting atomically thin layer of gallium oxide over their surface when exposed to oxygen...

Recently L1CAM was shown to be a promising biomarker for early-stage endometrial carcinoma (EC). As L1CAM expression was found to be related to serous ECs and areas of serous differentiation in endometrioid carcinomas, there is evidence that L1CAM-positive cancers more likely resemble type II carcinomas. Furthermore, expression of growth factor receptor HER2 has been found to be closely associated with serous ECs. We conducted a retrospective study on 142 patients in FIGO stages I and II with endometrioid EC and analyzed L1CAM and HER2 expression by double-staining immunohistochemistry...

PURPOSE: Keratoconus (KC) is thinning of the central cornea. Its etiology is unknown, but it may result from degrading of collagen type IV. The major protein in the cornea is collagen. Matrix metalloproteinase-9 (MMP-9) is able to degrade collagen type IV from the basement membrane and extracellular matrix (ECM). MMP-9 enzymatic activity is inhibited by the tissue inhibitor of metalloproteinase-1 (TIMP-1). In the present study, we sought to investigate and evaluate the effects of single nucleotide polymorphisms in COL4A3, MMP-9, and TIMP-1 on the risk of KC in an Iranian population sample...

In bioethics literature, the primary justification for the requirement of informed consent has been the protection of autonomous choices. To allow patients to be autonomous decision-makers, physicians are supposed to disclose and share information related to all treatment, procedures and risks. Advocates of the autonomy-based informed consent model argue that in informed consent cases, the disclosure of information should be according to the reasonable person standard or reasonable patient standard, rather than the average competent physician standard...
