Liquidation of the Bankruptcy Estate in Poland
2020
The purpose of this study is to present the general principles and general issues of liquidation of the bankruptcy estate under Polish law. It should be stressed that liquidation of the bankruptcy estate is intended to satisfy the creditors of the insolvent debtor. Therefore, the manner of liquidation of the bankruptcy estate has an obvious impact on the final bankruptcy dividend for the creditors. The rules governing the liquidation of the bankrupt’s assets are of the key-importance for the theory of law and the practice. The article defines the directional principles of liquidation of the bankruptcy estate, procedure of liquidation of the bankruptcy estate. The subject of this paper there…
A (1->3)-beta-D-glucan recognition protein from the sponge Suberites domuncula. Mediated activation of fibrinogen-like protein and epidermal growth f…
2004
Sponges (phylum Porifera) live in a symbiotic relationship with microorganisms, primarily bacteria. Until now, molecular proof for the capacity of sponges to recognize fungi in the surrounding aqueous milieu has not been available. Here we demonstrate, for the demosponge Suberites domuncula (Porifera, Demospongiae, Hadromerida), a cell surface receptor that recognizes (1--3)-beta-D-glucans, e.g. curdlan or laminarin. This receptor, the (1--3)-beta-D-glucan-binding protein, was identified and its cDNA analysed. The gene coding for the 45 kDa protein was found to be upregulated in tissue after incubation with carbohydrate. Simultaneously with the increased expression of this gene, two further…
Induction of heat-shock (stress) protein gene expression by selected natural and anthropogenic disturbances in the octocoral Dendronephthya klunzinge…
2000
Previously it was found that the expression of selected heat-shock proteins is upregulated in corals after exposure to elevated temperature. We published that HSPs are suitable markers in sponges to monitor the degree of environmental stress on these animals. In the present study the heat-shock proteins (HSPs) with a molecular weight of 90 kDa have been selected to prove their potential usefulness as biomarkers under controlled laboratory conditions and in the field. The studies have been performed with the octocoral Dendronephthya klunzingeri from which the cDNA coding for HSP90 was cloned first. The expression of the HSP90 gene is upregulated by thermal stress; treatment of the animals fo…
Cloning of cDNAs coding forCandida albicanscell surface proteins
1995
Two cDNA libraries were constructed from mRNAs obtained from yeast cells and germ-tubes of Candida albicans in lambda gt11. Immunoscreening with polyclonal antibodies raised against cell wall components allowed the detection of 29 positive clones. Two of these clones were selected for their specific reactivity with antisera either from yeast (clone 11Y) or germ-tubes (clone 24M). cDNA fragments were isolated by the digestion of lambda DNA with EcoRI. Southern blot analysis with these fragments as probes demonstrated homology with C. albicans DNA, and by Northern analysis two mRNAs transcripts were detected with sizes of approximately 1·5 kb for 11Y and 1·1 kb for 24M. Both transcripts were …
Mtha1, a Plasma Membrane H+-ATPase Gene fromMedicago truncatula,Shows Arbuscule-Specific Induced Expression in Mycorrhizal Tissue
2002
: Transport processes between plant and fungal cells are key elements in arbuscular mycorrhiza (AM), where H+-ATPases are considered to be involved in active uptake of nutrients from the symbiotic interface. Genes encoding H+-ATPases were identified in the genome of Medicago truncatula and three cDNA fragments of the H+-ATPase gene family (Mtha1 - 3) were obtained by RT-PCR using RNA from M. truncatula mycorrhizal roots as template. While Mtha2 and Mtha3 appeared to be constitutively expressed in roots and unaffected by AM development, transcripts of Mtha1 could only be detected in AM tissues and not in controls. Further analyses by RT-PCR revealed that Mtha1 transcripts are not detectable …
Proton-irradiated breast cells: molecular points of view
2019
Abstract Breast cancer (BC) is the most common cancer in women, highly heterogeneous at both the clinical and molecular level. Radiation therapy (RT) represents an efficient modality to treat localized tumor in BC care, although the choice of a unique treatment plan for all BC patients, including RT, may not be the best option. Technological advances in RT are evolving with the use of charged particle beams (i.e. protons) which, due to a more localized delivery of the radiation dose, reduce the dose administered to the heart compared with conventional RT. However, few data regarding proton-induced molecular changes are currently available. The aim of this study was to investigate and descri…
Identification of Metastasis Associated Antigen 1 (MTA1) by Serological Screening of Prostate Cancer cDNA Libraries
2008
Over the past 10 years the serological analysis of recombinant cDNA expression libraries (SEREX) has proved to be an effective method for the identification of tumour antigens. In the present study, two prostate cancer libraries were constructed and screened using autologous sera. Fifty five genes were isolated, including 46 known genes and 9 previously uncharacterised genes. Among the known genes, a metastasis-associated gene, MTA1, previously identified by differential cDNA hybridisation, was preferentially expressed in a panel of malignant tissues compared with normal tissues, as analysed by reverse transcriptase-polymerase chain reaction (RT-PCR). MTA1 transcripts were observed to be ov…
Peptides from NM23B - A Transcription Factor with NDP Kinase Activity - Are Expressed on the Surface of Leukemic Cells and Are Recognized by T-Lympho…
2005
Abstract Objective: During the last years a growing number of MHC-restricted antigens were recognized using autologous or HLA-matched cytotoxic T-cell lines (TCL). Molecules were isolated by HPLC or identified using cDNA expression cloning from normal or malignant target cells and found to derive from normal proteins or from mutated tumor-specific proteins. The majority of the tumor-specific peptides were derived from melanoma cells. The aim of this project was to search for immunogenic peptides on leukemia cells with the help of TCLs obtained from a stem cell donor against chronic myelogenous leukaemia (CML) recipient cells and to identify the immunogenic peptides by cDNA expression clonin…
A review of the biological and pharmacological activities of saponins.
1996
Summary This paper reviews the important biological and pharmacological activities of saponins reported over the last few years. These include cancer-related activity, as well as antiphlogistic and antiallergic, immunomodulating, antihepatotoxic, antiviral, hypoglycemic, antifungal and molluscicidal activities. The action of saponins on the cardiovascular, central nervous, and endocrine systems and other miscellaneous effects are also discussed.
La diversité de consommation de fromages dans la petite enfance : un facteur protecteur des maladies allergiques ?
2015
Introduction Une diversité alimentaire importante et précoce a été montrée protectrice vis à vis des maladies allergiques (Roduit C. et al, JACI 2012 Jul;130(1):130-6). L'effet de la diversité de consommation de fromages, riches en microorganismes, n'a pas été étudié. Or l'exposition aux microorganismes est suspectée pour son rôle protecteur sur la survenue de maladies allergiques. Le but de notre étude était d'évaluer l'effet protecteur de la diversité de consommation de fromages vis-à-vis de maladies allergiques (MA) : allergie alimentaire (AA), dermatite atopique (DA), asthme (AS), rhinite allergique (RA) et bronchite (BR). Méthodes L'étude a porté sur 941 enfants de la cohorte PATURE (P…
