Abstract
This paper describes the types of social comparison used by Hispanic students at a Hispanic Majority Institution through two studies (N = 406). We found that students engaged in upward identification more often than downward identification, downward contrast, and upward contrast. However, when comparing themselves on an academic measure, downward identification and upward contrast became relatively more frequent. Additionally, downward identification tended to predict higher self-reported confidence about academic abilities than other types of social comparison.

Abstract
BACKGROUND Induced pluripotent stem cell (iPSC)-derived cell therapies are an interesting new area in the field of regenerative medicine. One of the approaches to decrease the costs of iPSC-derived therapies is the use of allogenic homozygous human leukocyte antigen (HLA)-matched donors to generate iPSC lines and to build a clinical-grade iPSC bank covering a high percentage of the Spanish population. METHODS The Spanish Stem Cell Transplantation Registry was screened for cord blood units (CBUs) homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes. Seven donors were selected with haplotypes covering 21.37% of the haplotypes of the Spanish population. CD34-positive hematopoietic progenitors were isolated from the mononuclear cell fraction of frozen cord blood units from each donor by density gradient centrifugation and further by immune magnetic labeling and separation using purification columns. Purified CD34 + cells were reprogrammed to iPSCs by transduction with the CTS CytoTune-iPS 2.1 Sendai Reprogramming Kit. RESULTS The iPSCs generated from the 7 donors were expanded, characterized, banked and registered. Master cell banks (MCBs) and working cell banks (WCBs) from the iPSCs of each donor were produced under GMP conditions in qualified clean rooms. CONCLUSIONS Here, we present the first clinical-grade, iPSC haplobank in Spain made from CD34 + cells from seven cord blood units homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes within the Spanish population. We describe their generation by transduction with Sendai viral vectors and their GMP-compliant expansion and banking. These haplolines will constitute starting materials for advanced therapy medicinal product development (ATMP).

Abstract
Limb-girdle muscular dystrophy recessive 1 (LGMDR1) represents one of the most common types of LGMD in the population, where patients develop a progressive muscle degeneration. The disease is caused by mutations in calpain 3 gene, with over 500 mutations reported to date. However, the molecular events that lead to muscle wasting are not clear, nor the reasons for the great clinical variability among patients, and this has so far hindered the development of effective therapies. Here we generate human induced pluripotent stem cells (iPSCs) from skin fibroblasts of 2 healthy controls and 4 LGMDR1 patients with different mutations. The generated lines were able to differentiate into myogenic progenitors and myotubes in vitro and in vivo, upon a transient PAX7 overexpressing protocol. Thus, we have generated myogenic cellular models of LGMDR1 that harbor different CAPN3 mutations within a human genetic background, and which do not derive from muscular biopsies. These models will allow us to investigate disease mechanisms and test therapies. Despite the variability found among iPSC lines that was unrelated to CAPN3 mutations, we found that patient-derived myogenic progenitors and myotubes express lower levels of DMD, which codes a key protein in satellite cell regulation and myotube maturation.

Abstract
INTRODUCTION AND AIMS Insulin-like growth factor 1 is modulated by the insulin-like growth factor-binding proteins (IGFBPs) that are synthesized in the liver. The aim of the present study was to evaluate the concentrations of IGFBPs 1-7 in patients with chronic hepatitis C and study their association with fibrosis stage. PATIENTS AND METHODS A prospective, cross-sectional study was conducted that included patients with chronic hepatitis C. The stages of fibrosis were determined through FibroTest and FibroScan and the patients were compared with a control group. Serum levels of IGFBPs 1-7 were quantified through multiple suspension arrays. The Kruskal-Wallis test, Mann-Whitney U test, Spearman's correlation, and ROC curves were used for the statistical analysis. RESULTS Upon comparing the patients and controls, the highest concentrations were found in IGFBPs 1, 2, 4, and 7 (p=0.02, p=0.002, p=0.008, and p<0.001, respectively). IGFBP-3 levels had a tendency to be lower in the patients (p=0.066), whereas values were similar between patients and controls for IGFBP-5 and 6 (p=0.786 and p=0.244, respectively). Of the seven IGFBPs, IGFBP-3 concentrations were the highest. There were significant differences between fibrosis stages for IGFBP-5 and IGFBP-7. CONCLUSION IGFBPs play a relevant role in the fibrotic process in liver damage. IGFBP-7, in particular, differentiates fibrosis stages, making it a potential serum biomarker.

Abstract
We construct the Barut-Girardello coherent states for charge carriers in anisotropic 2D-Dirac materials immersed in a constant homogeneous magnetic field which is orthogonal to the sample surface. For that purpose, we solve the anisotropic Dirac equation and identify the appropriate arising and lowering operators. Working in a Landau-like gauge, we explicitly construct nonlinear coherent states as eigenstates of a generalized annihilation operator with complex eigenvalues which depends on an arbitrary function f of the number operator. In order to describe the anisotropy effects on these states, we obtain the Heisenberg uncertainty relation, the probability density, mean energy value and occupation number distribution for three different functions f . For the case in which the anisotropy is caused by uniaxial strain, we obtain that when the stress is applied along the x-axis of the material surface, the probability density for the nonlinear coherent states is smaller compared to when the material is stressed along the orthogonal axis.

Abstract
The vitamin D receptor (VDR) belongs to the nuclear class II receptor family. VDR is a ligand transcription factor and mediates the actions of calcitriol, the active product of vitamin D synthesis. Nowadays, it is known that the biological actions of calcitriol include the capacity to modulate cancer features, such as proliferation and differentiation, apoptosis, angiogenesis, invasion and metastasis. VDR expression has been demonstrated in human breast cancer and vitamin D has emerged as a promising targeted therapy. We analyse the VDR expression in normal and neoplastic canine mammary tissue samples and its relationship with clinicopathological parameters and progesterone/oestrogens receptors (PR/ER). Expression of VDR, Ki67 (to evaluate the proliferation index, PI), PR and ER was assessed in 50 mammary gland tissue samples from 41 female dogs by immunohistochemistry. VDR-positive staining was found in the nuclei of both myoepithelial and luminal epithelial cell layers. VDR expression was higher in normal mammary tissue (37/37 cases, 100%) then followed by benign tumours (6/15 cases, 40%) and malignant tumours (9/34 cases, 26.5%) (P = .001). Female dogs aged ≥10 years had lower VDR expression compared with dogs younger (P = .017). Relationship between VDR and breed, number of tumours, tumour size, histologic subtype, histologic grade of malignancy, PI and PR and ER expression was not observed. Studies with more samples are necessary to further evaluate the possible role of VDR in the biological behaviour of canine mammary tumours, and to corroborate the possibility to use the dog as model for human breast cancer.

Abstract
Essentials The Royal disease (RD) is a form of hemophilia B predicted to be caused by a splicing mutation. We generated an iPSC-based model of the disease allowing mechanistic studies at the RNA level. F9 mRNA analysis in iPSC-derived hepatocyte-like cells showed the predicted abnormal splicing. Mutated F9 mRNA level was very low but we also found traces of wild type transcripts. SUMMARY Background The royal disease is a form of hemophilia B (HB) that affected many descendants of Queen Victoria in the 19th and 20th centuries. It was found to be caused by the mutation F9 c.278-3A>G. Objective To generate a physiological cell model of the disease and to study F9 expression at the RNA level. Methods Using fibroblasts from skin biopsies of a previously identified hemophilic patient bearing the F9 c.278-3A>G mutation and his mother, we generated induced pluripotent stem cells (iPSCs). Both the patient's and mother's iPSCs were differentiated into hepatocyte-like cells (HLCs) and their F9 mRNA was analyzed using next-generation sequencing (NGS). Results and Conclusion We demonstrated the previously predicted aberrant splicing of the F9 transcript as a result of an intronic nucleotide substitution leading to a frameshift and the generation of a premature termination codon (PTC). The F9 mRNA level in the patient's HLCs was significantly reduced compared with that of his mother, suggesting that mutated transcripts undergo nonsense-mediated decay (NMD), a cellular mechanism that degrades PTC-containing mRNAs. We also detected small proportions of correctly spliced transcripts in the patient's HLCs, which, combined with genetic variability in splicing and NMD machineries, could partially explain some clinical variability among affected members of the European royal families who had lifespans above the average. This work allowed the demonstration of the pathologic consequences of an intronic mutation in the F9 gene and represents the first bona fide cellular model of HB allowing the study of rare mutations at the RNA level.

Abstract
Multiple sclerosis (MS) is considered a chronic autoimmune disease of the central nervous system that leads to gliosis, demyelination, axonal damage and neuronal death. The MS disease aetiology is unknown, though a polymorphism of the TNFRSF1A gene, rs1800693, is known to confer an increased risk for MS. Using retroviral delivery of reprogramming transgenes, we generated six MS patient-specific iPSC lines with two distinct genotypes, CC or TT, of the polymorphism rs1800693. iPSC lines had normal karyotype, expressed pluripotency genes and differentiated into the three germ layers. These lines offer a good tool to study MS pathomechanisms and for drug testing.

Abstract
BACKGROUND With the recent development of CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 genome editing technology, the possibility to genetically manipulate the human germline (gametes and embryos) has become a distinct technical possibility. Although many technical challenges still need to be overcome in order to achieve adequate efficiency and precision of the technology in human embryos, the path leading to genome editing has never been simpler, more affordable, and widespread. OBJECTIVE AND RATIONALE In this narrative review we seek to understand the possible impact of CRISR/Cas9 technology on human reproduction from the technical and ethical point of view, and suggest a course of action for the scientific community. SEARCH METHODS This non-systematic review was carried out using Medline articles in English, as well as technical documents from the Human Fertilisation and Embryology Authority and reports in the media. The technical possibilities of the CRISPR/Cas9 technology with regard to human reproduction are analysed based on results obtained in model systems such as large animals and laboratory rodents. Further, the possibility of CRISPR/Cas9 use in the context of human reproduction, to modify embryos, germline cells, and pluripotent stem cells is reviewed based on the authors' expert opinion. Finally, the possible uses and consequences of CRISPR/cas9 gene editing in reproduction are analysed from the ethical point of view. OUTCOMES We identify critical technical and ethical issues that should deter from employing CRISPR/Cas9 based technologies in human reproduction until they are clarified. WIDER IMPLICATIONS Overcoming the numerous technical limitations currently associated with CRISPR/Cas9 mediated editing of the human germline will depend on intensive research that needs to be transparent and widely disseminated. Rather than a call to a generalized moratorium, or banning, of this type of research, efforts should be placed on establishing an open, international, collaborative and regulated research framework. Equally important, a societal discussion on the risks, benefits, and preferred applications of the new technology, including all relevant stakeholders, is urgently needed and should be promoted, and ultimately guide research priorities in this area.

Abstract
Fanconi anemia (FA) is a complex genetic disease associated with a defective DNA repair pathway known as the FA pathway. In contrast to many other FA proteins, BRCA2 participates downstream in this pathway and has a critical role in homology-directed recombination (HDR). In our current studies, we have observed an extremely low reprogramming efficiency in cells with a hypomorphic mutation in Brca2 (Brca2(Δ) (27/) (Δ27)), that was associated with increased apoptosis and defective generation of nuclear RAD51 foci during the reprogramming process. Gene complementation facilitated the generation of Brca2(Δ) (27/) (Δ27) induced pluripotent stem cells (iPSCs) with a disease-free FA phenotype. Karyotype analyses and comparative genome hybridization arrays of complemented Brca2(Δ) (27/) (Δ27) iPSCs showed, however, the presence of different genetic alterations in these cells, most of which were not evident in their parental Brca2(Δ) (27/) (Δ27) mouse embryonic fibroblasts. Gene-corrected Brca2(Δ) (27/) (Δ27) iPSCs could be differentiated in vitro toward the hematopoietic lineage, although with a more limited efficacy than WT iPSCs or mouse embryonic stem cells, and did not engraft in irradiated Brca2(Δ) (27/) (Δ27) recipients. Our results are consistent with previous studies proposing that HDR is critical for cell reprogramming and demonstrate that reprogramming defects characteristic of Brca2 mutant cells can be efficiently overcome by gene complementation. Finally, based on analysis of the phenotype, genetic stability, and hematopoietic differentiation potential of gene-corrected Brca2(Δ) (27/) (Δ) (27) iPSCs, achievements and limitations in the application of current reprogramming approaches in hematopoietic stem cell therapy are also discussed.

Abstract
Human embryonic stem cells (hESC) and induced pluripotent stem cells (iPSC) offer great hope for in vitro modeling of Parkinson's disease (PD), as well as for designing cell-replacement therapies. To realize these opportunities, there is an urgent need to develop efficient protocols for the directed differentiation of hESC/iPSC into dopamine (DA) neurons with the specific characteristics of the cell population lost to PD, i.e., A9-subtype ventral midbrain DA neurons. Here we use lentiviral vectors to drive the expression of LMX1A, which encodes a transcription factor critical for ventral midbrain identity, specifically in neural progenitor cells. We show that clonal lines of hESC engineered to contain one or two copies of this lentiviral vector retain long-term self-renewing ability and pluripotent differentiation capacity. Greater than 60% of all neurons generated from LMX1A-engineered hESC were ventral midbrain DA neurons of the A9 subtype, compared with ∼10% in green fluorescent protein-engineered controls, as judged by specific marker expression and functional analyses. Moreover, DA neuron precursors differentiated from LMX1A-engineered hESC were able to survive and differentiate when grafted into the brain of adult mice. Finally, we provide evidence that LMX1A overexpression similarly increases the yield of DA neuron differentiation from human iPSC. Taken together, our data show that stable genetic engineering of hESC/iPSC with lentiviral vectors driving controlled expression of LMX1A is an efficient way to generate enriched populations of human A9-subtype ventral midbrain DA neurons, which should prove useful for modeling PD and may be helpful for designing future cell-replacement strategies.

Abstract
BACKGROUND Given the significant drawbacks of using human embryonic stem (hES) cells for regenerative medicine, the search for alternative sources of multipotent cells is ongoing. Studies in mice have shown that multipotent ES-like cells can be derived from neonatal and adult testis. Here we report the derivation of ES-like cells from adult human testis. METHODS Testis material was donated for research by four men undergoing bilateral castration as part of prostate cancer treatment. Testicular cells were cultured using StemPro medium. Colonies that appeared sharp edged and compact were collected and subcultured under hES-specific conditions. Molecular characterization of these colonies was performed using RT-PCR and immunohistochemistry. (Epi)genetic stability was tested using bisulphite sequencing and karyotype analysis. Directed differentiation protocols in vitro were performed to investigate the potency of these cells and the cells were injected into immunocompromised mice to investigate their tumorigenicity. RESULTS In testicular cell cultures from all four men, sharp-edged and compact colonies appeared between 3 and 8 weeks. Subcultured cells from these colonies showed alkaline phosphatase activity and expressed hES cell-specific genes (Pou5f1, Sox2, Cripto1, Dnmt3b), proteins and carbohydrate antigens (POU5F1, NANOG, SOX2 and TRA-1-60, TRA-1-81, SSEA4). These ES-like cells were able to differentiate in vitro into derivatives of all three germ layers including neural, epithelial, osteogenic, myogenic, adipocyte and pancreatic lineages. The pancreatic beta cells were able to produce insulin in response to glucose and osteogenic-differentiated cells showed deposition of phosphate and calcium, demonstrating their functional capacity. Although we observed small areas with differentiated cell types of human origin, we never observed extensive teratomas upon injection of testis-derived ES-like cells into immunocompromised mice. CONCLUSIONS Multipotent cells can be established from adult human testis. Their easy accessibility and ethical acceptability as well as their non-tumorigenic and autogenic nature make these cells an attractive alternative to human ES cells for future stem cell therapies.

Abstract
A 13-year-old, female, mixed, cocker spaniel was examined for a unilateral exophthalmia and protruding mass in episcleral region of the right eye. Mode B ocular ultrasonography revealed a mass extended intraocular from anterior chamber to posterior pole without evidence of extraocular extension. A presumptive diagnosis of melanocytic tumour was made. A complete blood count and chemistry and thoracic radiographs did not show any abnormal changes. The recommended treatment was enucleation, and melanocytic nature of the tumour was confirmed by immunohistochemistry. Three months after surgery, the animal showed a status epilepticus refractory to treatment. Computed tomographic examination of the brain revealed changes compatible with a tumour. Cerebrospinal fluid analysis was normal. Because of the poor clinical prognosis, the owners elected to have the dog euthanased.

Abstract
Human embryonic stem (hES) cells represent a potential source for cell replacement therapy of many degenerative diseases. Most frequently, hES cell lines are derived from surplus embryos from assisted reproduction cycles, independent of their quality or morphology. Here, we show that hES cell lines can be obtained from poor-quality blastocysts with the same efficiency as that obtained from good- or intermediate-quality blastocysts. Furthermore, we show that the self-renewal, pluripotency, and differentiation ability of hES cell lines derived from either source are comparable. Finally, we present a simple and reproducible embryoid body-based protocol for the differentiation of hES cells into functional cardiomyocytes. The five new hES cell lines derived here should widen the spectrum of available resources for investigating the biology of hES cells and advancing toward efficient strategies of regenerative medicine.

Abstract
The non-collagenous C-terminal domain of the alpha(3) chain of collagen IV is the autoantigen in Goodpasture disease, an autoimmune disorder described only in humans. Specific N-terminal phosphorylation is a biological feature unique to the human domain when compared with other homologous domains lacking immunopathogenic potential. We have recently cloned from a HeLa-derived cDNA library a novel serine/threonine kinase (Goodpasture antigen-binding protein (GPBP)) that phosphorylates the N-terminal region of the human domain (Raya, A. Revert, F, Navarro, S. and Saus J. (1999) J. Biol. Chem. 274, 12642-12649). We show here that the pre-mRNA of GPBP is alternatively spliced in human tissues and that the most common transcript found encodes GPBPDelta26, a molecular isoform devoid of a 26-residue serine-rich motif. Recombinantly expressed GPBPDelta26 exhibits lower activity than GPBP, due at least in part to a reduced ability of GPBPDelta26 to interact and to form very active high molecular weight aggregates. In human tissues, GPBP shows a more limited expression than GPBPDelta26 but displays a remarkable preference for the small vessels and for histological structures targeted by natural autoimmune responses including alveolar and glomerular basement membranes, the two main targets in Goodpasture disease. GPBP expression is, in turn, up-regulated in the striated muscle of a Goodpasture patient and in other autoimmune conditions including cutaneous lupus erythematosus, pemphigoid, and lichen planus.

Abstract
Goodpasture disease is an autoimmune disorder that occurs naturally only in humans. Also exclusive to humans is the phosphorylation process that targets the unique N-terminal region of the Goodpasture antigen. Here we report the molecular cloning of GPBP (Goodpasture antigen-binding protein), a previously unknown 624-residue polypeptide. Although the predicted sequence does not meet the conventional structural requirements for a protein kinase, its recombinant counterpart specifically binds to and phosphorylates the exclusive N-terminal region of the human Goodpasture antigen in vitro. This novel kinase is widely expressed in human tissues but shows preferential expression in the histological structures that are targets of common autoimmune responses. The work presented in this report highlights a novel gene to be explored in human autoimmunity.

Abstract
Administration of high doses (150-250 mg/kg body weight) of phenytoin (DPH) promote a 40% decrease in glutathione (GSH) content of rat sciatic nerve. This DPH-induced GSH depletion is accompanied with an electrophysiological impairment of peripheral neuromuscular function. H7 (20 mg/kg body weight IP, 30 min prior to DPH), a protein kinase C inhibitor, was able to prevent the DPH-induced GSH depletion only at the lower DPH dose used. This same inhibitor completely prevented the electrophysiological impairment at the lower DPH dose, and only partially at the higher DPH dose used. These results confirm the hypothesis of a DPH-dependent activation of PKC (that might be triggered by, or be the consequence of, the reduction of the intracellular antioxidant GSH), as one of the pathophysiological mechanisms involved in DPH-induced neurotoxicity.

Abstract
OBJECTIVE To determine whether lipoic acid (LA) will reduce oxidative stress in diabetic peripheral nerves and improve neuropathy. RESEARCH DESIGN AND METHODS We used the model of streptozotocin-induced diabetic neuropathy (SDN) and evaluated the efficacy of LA supplementation in improving nerve blood flow (NBF), electrophysiology, and indexes of oxidative stress in peripheral nerves affected by SDN, at 1 month after onset of diabetes and in age-matched control rats. LA, in doses of 20, 50, and 100 mg/kg, was administered intraperitoneally five times per week after onset of diabetes. RESULTS NBF in SDN was reduced by 50%; LA did not affect the NBF of normal nerves but improved that of SDN in a dose-dependent manner. After 1 month of treatment, LA-supplemented rats (100 mg/kg) exhibited normal NBF. The most sensitive and reliable indicator of oxidative stress was reduction in reduced glutathione, which was significantly reduced in streptozotocin-induced diabetic and alpha-tocopherol-deficient nerves; it was improved in a dose-dependent manner in LA-supplemented rats. The conduction velocity of the digital nerve was reduced in SDN and was significantly improved by LA. CONCLUSIONS These studies suggest that LA improves SDN, in significant part by reducing the effects of oxidative stress. The drug may have potential in the treatment of human diabetic neuropathy.

Abstract
The study described here was designed to develop and test a form of nursing assessment of mental patients for use as a basis for individualized holistic nursing care in any setting. Nursing assessment was made of 581 mental patients receiving care in either mental hospitals, psychiatric departments of general hospitals or in mental health centres. Subjects were observed, interviewed and asked to complete a structured assessment form. Major variables studied were physical nursing problems/needs with nine categories, psychosocial nursing problems/needs with nine categories, sex, age, and physical and psychiatric disorders. Data were analysed with frequency distribution and comparative techniques, correlational procedures, and the multiple linear regression statistical procedure. The frequency distribution of psychiatric diagnoses showed that schizophrenic disorders were the most frequent in the total sample. However, there were more depressive patients in the general hospital group. Physical nursing problems/needs were significantly related with psychosocial nursing problems/needs, affective-depressive disorders, sex and age as well as negatively related with psychotic and anxiety disorders. Psychosocial nursing problems/needs were significantly related with schizophrenic and psychotic disorders, physical disorders and with the younger age groups. It was concluded that the psychiatric nursing assessment should encompass the areas of personal characteristics, and physical and psychological problems of the patient, and thus lead to practicing psychiatric nursing, that is, holistic psychosomatic nursing.

Abstract
The relaxant effect of 4-hydroxynonenal (4-HNE), a lipid peroxidation product, on human cerebral arteries was studied. Addition of 4-HNE to artery rings promoted no contraction, and after stimulation with prostaglandin F2 alpha (PFG2 alpha; 10(-7)-3 x 10(-6) M), 100% relaxation was obtained with 3 x 10(-5) M 4-HNE. Inhibition of nitric oxide formation with NG-nitro-L-arginine methyl ester hydrochloride (L-NAME; (10(-4) M), as well as prostaglandin synthesis with indomethacin (3 x 10(-6) M), partially prevented 4-HNE-induced relaxation, but each of these substances separately failed to inhibit complete relaxation. Addition of both inhibitors together reduced 4-HNE-induced relaxation to approximately 50%, but relaxation could not be abolished. When the endothelium was removed, 4-HNE did not promote relaxation after PGF2 alpha stimulation. The possible roles of different intracellular signaling systems in the vascular effect of 4-HNE are discussed.

Abstract
The action of caffeine on peripheral neuromuscular function was studied by means of in vivo determinations of electrophysiological parameters, i.e., amplitude of extracellularly recorded muscle action potentials and nerve conduction velocity in the dorsal skeletal muscle and caudal nerve of the rat tail, respectively. Repeated exposure of the rats was carried out by adding caffeine to the drinking water for 10 days. Here we report the novel finding that motor nerve conduction velocity showed a significant decrease in caffeine-treated animals, whereas no change was observed in the amplitude of indirectly evoked extracellular muscle action potentials. The physiological recovery of the amplitude of the compound muscle action potential observed in nonintoxicated rats after high-frequency stimulation (10 Hz) was not observed in intoxicated animals and is also discussed.

Abstract
Thiobarbituric acid reactive substances (TBARS) concentration in serum has been determined in healthy subjects and in patients suffering acute hepatitis and chronic cases of hepatitis C. Treatment with interferon of the chronic active hepatitis C patients, 5 x 10(6) U three times a week during 2 months, led in those patients whose SGPT activity normalized in serum, to a concomitant decrease in serum TBARS content. The possible theoretical involvement of peroxidation and antioxidants in this beneficial effect of interferon in hepatitis C patients is discussed. The results presented confirm the value of TBARS as laboratory test in the management of liver diseases and as a useful tool for the study of pathogenic and/or therapeutic mechanisms of this viral infection.

Abstract
The effect of alloxan-induced diabetes on glutathione peroxidase (GSH-Px) activity in sciatic nerve of mice has been studied. We have found, 7 days after alloxan treatment, a significant decrease in this enzymatic activity in the cytosol of sciatic nerve of diabetic mice, and moreover, that these changes remained unaltered up to 21 days after alloxan injection. No modification in the glutathione content of sciatic nerve of diabetic mice was observed throughout the experiment when compared with controls. The decrease in GSH-Px activity in this tissue shows a good correlation with the increase of blood glucose levels throughout the experiment. It is hypothesized whether a combination of mechanisms could be involved in this decrease of GSH-Px activity and if oxygen radicals might be the common mediators of these processes.

Abstract
The major aspects of the glutathione (GSH)-related antioxidant defense of human retina are presented. These include concentration of GSH and activities of some GSH-dependent enzymes: glutathione peroxidase, glutathione disulfide reductase, and glutathione S-transferase toward a broad spectrum substrate 1-chlor-2,4-dinitrobenzene and a toxic product of lipid peroxidation (4-hydroxynonenal). The presence of a relatively high GSH concentration, GSH peroxidase activity, and GSH S-transferase specific activity toward 4-hydroxynonenal in human retina might constitute a central defense mechanism in inflammation-promoted oxidative stress and subsequent lipid peroxidation. The use of different substrates for the determination of the GSH peroxidase activity showed no statistically significant difference, thus suggesting the lack of Se-independent GSH peroxidase in human retina. Large individual variations were obtained for GSH concentration and the different activities tested; the apparent correlation with age of these findings is currently under investigation.

Abstract
The neurotoxic effects of a single dose of phenytoin (150 mg/kg body weight) alone or 30 min after H7 (a protein kinase C inhibitor) injection (20 mg/kg body weight) were investigated in terms of peripheral neuromuscular function and Na+,K(+)-ATPase activity of the sciatic nerve. This intraperitoneal injection of phenytoin induced complete blockade of muscle action potentials in the dorsal segmental muscles of the rat tail evoked by electric stimulation of the caudal nerve and a 40% decrease in the Na+,K(+)-ATPase activity of the rat sciatic nerve when compared with control values, measured as the difference between total and ouabain-insensitive ATPase activity. Prior administration of H7 resulted in the complete prevention of both effects. Implications of protein kinase C inhibition in phenytoin neurotoxicity are discussed.

Abstract
This article presents the results of a research study on 547 mental patients testing a form of nursing assessment of mental patients in psychiatric and in general hospitals, as a means to assess their nursing needs and as a basis for planning, implementation and evaluation of their personalized holistic nursing care. The study showed that more depressive than schizophrenic patients went to the general hospital for help. The reverse was observed in the psychiatric hospital. The psychological nursing needs of the patients were significantly correlated with their somatic nursing needs. The psychological as well as the somatic nursing needs of the patients were significantly correlated with sex, age, somatic health state and mental health state in general, and not with their concrete psychiatric diagnosis. It is concluded that the psychiatric nursing assessment should be oriented towards the investigation of the patient's psychosomatic nursing needs rather than be based on his medical diagnosis.

Abstract
We studied the acute effects of a single dose of phenytoin (250 mg/kg) on peripheral neuromuscular function. The evoked muscle action potentials of the dorsal segmental muscles in the rat tail, and the conduction velocity of the dorsal nerve trunk which innervates them, were measured before and after the intraperitoneal injection of phenytoin. The experiments were performed at different temperatures, 27 (physiological tail temperature), 36 and 37 degrees C (physiological central temperature) in different groups of animals. The amplitudes of the evoked muscle action potentials in the treated groups showed no significant modifications at 27 degrees C, at 36 degrees C a small nonsignificant decrease could be observed, and a complete block occurred at 37 degrees C. The mean blocking time was approximately one hour. No significant variations of conduction velocity were observed at 27 and 36 degrees C, whereas it decreased significantly after 30 minutes at 37 degrees C. The results presented confirm phenytoin toxicity. How far these results, especially the decrease of nerve conduction velocity observed at 37 degrees C, confirm a previous hypothesis which supported that peripheral and central nervous system are affected by phenytoin by similar mechanisms, is discussed.

Abstract
This paper aims to reflect upon the educational task of the university, to consider whether knowledge can be promoted and values ignored, and thus to explore the implications for nursing education. The university is the cradle which nurtures intellectuals, professionals and scientists as whole human beings. Paced by the spirit and the ideals of paideia, it cannot be limited merely to developing the student's mind. It should also inspire the student with a belief in the higher values of life, as a compass in his profession. (Paideia is an ancient Greek conception of the ideal human education. It includes modern notions such as civilization, culture, tradition, literature, philosophy and education. It means formation of the human being of any age, as an independent, free and virtuous whole person.) Values, when transmitted by all teachers of all subjects within the educational structures of the university, can increase the student's respect for truth, for the worth and the rights of other persons, his appreciation of his own worth, assets and limitations, his love of wisdom and desire to serve humanity, his outlook about man's position in the world and his inquiring mind in order to discover higher perspectives of life. Only in this way does university become a worthy centre of paideia for educating nurses committed and aspiring to provide holistic, personalized, quality nursing care to people, as well as to determine and shape the future of nursing education in the midst of our technological, computerized, and some would say dehumanized era, propelling itself into the twenty-first century.

Abstract
The effects of the administration of cyclophosphamide to male rats at doses of 400 mg/m2 for a period of 5 days and of 200 mg/m2 over two five-day cycles interrupted by a 21-day break reveal differences in the ultrastructural morphology of gonadotrophic cells between treated animals and normal controls. The ultrastructural data obtained coincide with the results obtained from the measurement of serum FSH and LH levels, indicating hypofunction. A significant fall was also recorded in blood testosterone levels. The two types of treatment did not give rise to morphological or functional differences.

Abstract
Cyclophosphamide administered at doses of 400 mg/m2/5 days with sacrifice two days later, and 200 mg/m2/5 days with a 21-day break and a further five days of treatment, with sacrifice two days later, provokes similar effects. Functional activity is less marked in untreated and control animals than in treated ones, as the hormone data shows. But the ultrastructure of PRL cells in treated animals indicates the existence of clear hormone synthesis activity, evident in the fusion and clustering of granules at differing stages of maturity, etc.
