Autogenic Training in Mental Disorders: What Can We Expect?

Autogenic training (AT) is a well-established self-induced relaxation technique based on autosuggestion. From the past two decades, an increasing number of AT studies strongly suggests the practical usefulness of psychophysiological relaxation in the area of medicine. Despite this interest, to date, limited critical clinical reflection on the application and effects of AT in mental disorders exists.

BRCA1-regulated RRM2 expression protects glioblastoma cells from endogenous replication stress and promotes tumorigenicity.

Oncogene-evoked replication stress (RS) fuels genomic instability in diverse cancer types. Here we report that BRCA1, traditionally regarded a tumour suppressor, plays an unexpected tumour-promoting role in glioblastoma (GBM), safeguarding a protective response to supraphysiological RS levels. Higher BRCA1 positivity is associated with shorter survival of glioma patients and the abrogation of BRCA1 function in GBM enhances RS, DNA damage (DD) accumulation and impairs tumour growth.

Multigenerational lifetime low-dose exposure to heavy metals on selected reproductive parameters in rats.

The aim of the present investigation was to evaluate the effects of multigenerational (P, F1 and F2) exposure to low doses of lead, mercury and cadmium dissolved in tap water on the reproductive potency of Wistar rats and the physical health of their progeny. The animals were divided into 4 groups - control (C) and 3 groups intoxicated by metals (Pb, 100 μM; Hg, 1 μM; Cd, 20 μM, respectively). Females gave births from the 13th to the 78th week of experiment.

Age dependency on some physiological and biochemical parameters of male Wistar rats in controlled environment.

The aim of the study was to assess the age dependence on some physiological and serum chemistry parameters of male Wistar rats for the estimation of reference values in controlled environment. We are presenting values obtained from a large number of animals such as survival, average life span, body mass, food and water intake, serum chemistry parameters as total protein, albumin, transferrin and ferritin in serum. One part of this work compares the relationship between rat and human age.

Analysis of Snail-1, E-cadherin and claudin-1 expression in colorectal adenomas and carcinomas.

We report the expression of Snail-1, E-cadherin and claudin-1 by indirect immunohistochemistry in colonic neoplasia. Snail-1 is a zinc finger transcription factor expressed in cells that already have undergone almost complete epithelial-mesenchymal transition (EMT) and have already evaded from the tumor. The main mechanism by which Snail induces EMT is downregulation of E-cadherin, of which expression was shown to be frequently downregulated in many different types of tumors, where it accompanies the invasiveness and metastatic behavior of malignant cells.

Identification of CD133+/nestin+ putative cancer stem cells in non-small cell lung cancer.

Aims: No effective treatment for lung cancer exists currently. One reason for this, is the development of drug resistance, assumed to be associated with cancer stem cell (CSCs) emergence within the tumour. This pilot study aimed to identify CSCs in 121 non-small cell lung cancer (NSCLC) patient samples via detection of the expression of stem cell markers - CD133 and nestin.

Immunohistochemical assessment of E-cadherin and beta-catenin in trichofolliculomas and trichoepitheliomas.

Background: Trichofolliculomas and trichoepitheliomas are benign skin neoplasms originating from hair follicle cells. They result from defects in the signaling pathways that regulate hair follicle morphogenesis and regeneration. Thus they seem to be an excellent model of these processes.

Could changes in the regulation of the PI3K/PKB/Akt signaling pathway and cell cycle be involved in astrocytic tumor pathogenesis and progression?

The most frequent alterations found in astrocytomas are two major groups of signaling proteins: the cell cycle and the growth factor-regulated signaling pathways. The aim of our study was to detect changes in expression of the following proteins: the tumor suppressors PTEN, p53, and p21Waf1/Cip1, glial fibrillary acidic protein (GFAP, as a marker of astroglial differentiation), the phosphorylated form of protein kinase B/Akt (PKB/Akt), which is downstream to the epidermal growth factor receptor (EGFR), and MDM2, which degrades p53. Paraffin-embedded astrocytoma tissue samples from 89 patients were divided into low grade (grade I-II; 42 samples) and high grade astrocytomas (grade III-IV; 47 samples).

Molecular changes in PDEGF and bFGF in malignant melanomas in relation to the stromal microenvironment.

Background: Aberrant expression of either growth factors or growth factor-receptors by stromal cells can be an important factor promoting the growth of solid tumours. It may also affect differentiation of malignant cells and support tumour spread. The aim of the present study was to investigate the hypothesis that basic-fibroblast growth factor (bFGF) and platelet-derived growth factor (PDEGF) may be involved in tumour-stromal microenvironment interactions in primary malignant melanomas.

[Immunohistochemical study of the apoptotic and proliferative mechanisms in the intestinal mucosa during coeliac disease].

Mechanisms leading to morphological changes of the small intestine during coeliac disease are not yet completely recognized, however, two main processes have been suggested recently: remodelling of mucosa by matrix metalloproteinases, and mucosal atrophy by apoptosis. The aim of this study was to analyze the expression of proteins regulating apoptosis and some markers of proliferation in the mucosa of the small intestine of children with active (ACD) and latent form (LCD) of coeliac disease (CD). Intestinal biopsies of 43 children with ACD and LCD were analyzed by standard indirect immunohistochemical technique for Fas, Fas ligand (Fas-L), tissue transglutaminase (tTG), Bcl-2, Bid, glutathione S-transferase (GST), CAS 3, CAS 8, PARP, Ki-67, Topoisomerase IIa, PCNA expression.

Expression of the hMLH1 and hMSH2 proteins in normal tissues: relationship to cancer predisposition in hereditary non-polyposis colon cancer.

The majority of tumours in patients with hereditary non-polyposis colon cancer (HNPCC) occur in large intestine and endometrium; also, other tissues are at increased risk. We studied expression of hMLH1 and hMSH2 proteins in 148 normal samples of various tissues from non-HNPCC patients and in 14 normal colon tissues from HNPCC patients. Immunohistochemical technique was used.

Immunohistochemical detection of the hMLH1 and hMSH2 proteins in hereditary non-polyposis colon cancer and sporadic colon cancer.

Defects in DNA mismatch repair system are involved in carcinogenesis of sporadic and inherited human cancers. We assessed the feasibility of using immunohistochemistry to detect tumors with DNA mismatch repair deficiency. We analyzed 81 samples (74 colon cancers (CC), 1 colon dysplasia and 6 extracolonic cancers) for hMLH1 and hMSH2 protein expression, microsatellite instability (MSI) and/or mutational analysis.

Proto-oncogene c-myc in uterine cervix carcinogenesis.

The biological behaviour of precancerous and early stages of uterine cervix carcinoma is not always easily predictable. It is important therefore to identify new biological markers which could more reliably predict the evolution of the disease or provide important therapeutic targets. To establish the role of the proto-oncogene c-myc in uterine cervix tumorigenesis, we examined 96 tissue samples of different degrees of cervical intraepithelial neoplasia (CIN1-CIN 3), in situ (CIS) or invasive squamous cell carcinoma (ISCC) and control cases.

Effect of boar seminal plasma and seminal vesicle fluid on porcine lymphocytes.

Boar seminal plasma and seminal vesicle fluid inhibited mitogen-induced blastic transformation of porcine lymphocytes. Chromatographic separation of seminal vesicle fluid on Sephadex G-100 yielded four fractions. Only the SV-1 fraction displayed significant inhibition of blastic transformation.

The effect of haemagglutinating factor from boar seminal vesicle fluid on leucocytes.

Complete agglutination of porcine, bovine, ovine, and rabbit leucocytes and of porcine and bovine thrombocytes was observed after their exposure to a 1% solution of the haemagglutinating protein isolated from boar seminal fluid. Bull seminal vesicle fluid had the same agglutinating effect on leucocytes, but did not agglutinate thrombocytes. Ram seminal plasma and other fluids from the reproductive tract of boar and bull did not agglutinate either leucocytes or thrombocytes.

First attempt to characterize 3H-fucose acrosomal label in spermatoza.

Acrosomes of rabbit spermatozoa were labelled by tritiated fucose introduced into the cells during spermatogenesis. The labelling was analysed simultaneously by autoradiography and biochemically. In compact intact acrosomes the labelling was confined strictly to the acrosomal region of the sperm head.

Isolation of acidic acrosin isoinhibitors (BUSI I A, BUSI IB1 and BUSI I B2) from bull seminal plasma.

Three natural proteinase isoinhibitors with low isoelectric points BUSI I A (pI = 3.9), BUSI I B1 (pI = 3.4 and BUSI I B2 (pI = 3.

Isolation of basic acrosin inhibitor from bull seminal plasma (BUSI II).

An acrosin inhibitor was isolated from bull seminal plasma by gel filtration on Sephadex G-50 fine and ion-exchange chromatography on CM-Sephadex. The inhibitor is a basic polypeptide (pl greater than or equal to 10.5) of molecular weight 6 200 (calculated from amino acid composition).
