Objective: The diagnostic sensitivity and specificity of conventional methods for superficial lymph node tuberculosis (LNTB) are not ideal. We evaluated several novel methods including Xpert Mycobacterium tuberculosis/rifampicin (Xpert MTB/RIF) technology, quantitative fluorescence Polymerase Chain Reaction (qPCR) and High-Resolution Melting Curve (HRMC) in the diagnosis of superficial lymph node TB. Methods: Specimens from eighty-one consecutive patients with suspected LNTB and thirteen cases with...

Tissue engineering focuses on developing biological substitutes to restore, maintain or improve tissue functions. The three main components of its application are scaffold, cell and growthstimulating signals. Scaffolds composed of biomaterials mainly function as the structural support for ex vivo cells to attach and proliferate. They also provide physical, mechanical and biochemical cues for the differentiation of cells before transferring to the in vivo site. Collagen has been long used in various...

Background: Vascular endothelial growth factor (VEGF)-C, -D, and VEGF receptor-3 are proteins characterized as crucial for tumor lymphangiogenesis. It is accompanied by angiogenesis during wound healing, but also in the neoplastic process. The research studies have shown that the lymphatic system plays a key role in the progression of carcinogenesis. Objective: The aim of this study was to evaluate changes in the expression of VEGF-C, VEGF-D and VEGFR-3 in different grades of endometrial cancer...

Background: Biodegradable films are appropriate alternatives to synthetic polymers due to their potential to enhance food safety and their function as a carrier for wide a range of food additives especially natural antioxidants. Objective: The aim of this study was to compare the potential antioxidant activities of sodium alginate films containing resveratrol (RES) alone and in combination with Zataria multiflora essential oil (ZEO) using an in vitro model. Methods: At first, the major chemical...

Background: The protective effects of heat shock proteins (Hsps) were studied in some infectious and non-infectious diseases, but their specificity was slightly known in various disorders. Among Hsps, small Hsps (e.g. Hsp27 and Hsp20) have important roles in protein folding and translocation, and also in immunity. Methods: In this study, overexpression of Hsp20 and Hsp27 was performed by transfection of the plasmids encoding Hsp20 and Hsp27 (pEGFP-Hsp20 and pEGFP-Hsp27) into Huh7.5, Hela and Vero...

Background & Objective: Corneal endothelial cells (ECD) are characterized by limited regenerative potential, which is additionally impaired in patients with diabetes. This retrospective study included 27 patients aged 58.1±13.6, 16 female and 11 males, who underwent 23-gauge vitrectomy in combination with cataract surgery (phacovitrectomy) and further Ex-PRESS shunt implantation throughout 2013-2017 at St. Barbara Hospital in Sosnowiec, Poland. Methods: In our study, we distinguished 4 periods:...

Background: Bacillus thuringiensis toxins are effective against multiple biological targets such as insects, nematodes, mites, protozoa, and importantly, human cancer cells. One of the main mechanisms by which Cry toxins to trigger cell death is the specific recognition of cadherin-like membrane cell receptors. Objective: This work aimed to assess the cytotoxicity of the Cry1Ab and Cry1Ac toxins from Bacillus thuringiensis in HeLa, cervical cancer cell line, as well as their antitumor activity in...

Objective: The present study was aimed to evaluate the effect of the aqueous extract of Tinospora cordifolia (AETC) against cyclophosphamide-induced immunosuppression and systemic Candida albicans infection in a murine model. Methods: The protective effect of AETC against cyclophosphamide-induced leukopenia was evaluated by quantitative and qualitative analysis of the leukocytes. The immune-stimulating potential of AETC on macrophages was assessed by determining the levels of secreted cytokines....

Background & Objective: The present study was aimed at characterizing the conformational alterations induced in human transferrin, the iron regulatory protein by glyoxal. Since protein aggregation is at the core of many disorders, thus interest in this domain has increased significantly during the past years. Methods: In our present study, the effect of glyoxal was monitored on human transferrin using multispectroscopic and multi-microscopic studies. Results: Intrinsic fluorescence spectroscopy...

Due to some inconsistencies in the figures provided by the first author that have come to light, and after a thorough investigation we would like to retract our paper: “Low doses of CPS49 and flavopiridol combination as potential treatment for advanced prostate cancer. By: Zalazar F, De Luca P, Gardner K, Figg WD, Meiss R, Spallanzani RG, Vallecorsa P, Elguero B, Cotignola J, Vazquez E, De Siervi A. Curr. Pharm. Biotechnol., 2015, 16(6), 553-63.
