Implication of core beliefs about negative-self in neuroticism

Abstract

Objective: Core beliefs about negative-self are beliefs about self-deficiencies in basic aspects of human adaptation. Meanwhile, neuroticism is a personality trait characterised by negative emotionality, i.e., a tendency to react to stress with negative emotions. The present study tested the hypothesis that core beliefs about negative-self are implicated in neuroticism.

Methods: The subjects were 309 Japanese healthy volunteers. Core beliefs about negative-self were evaluated by the Brief Core Schema Scales, and neuroticism was evaluated by the NEO Personality Inventory-Revised.

Results: In both multiple regression analysis and structural equation modelling, higher neuroticism was strongly predicted by higher levels of core beliefs about negative-self.

Limitations: The present study cannot determine the causal relationship between core beliefs about negative-self and neuroticism, because of its cross sectional design.

Conclusions: The present study suggests that core beliefs about negative-self are deeply implicated in neuroticism.

• Key Points

• Implication of core beliefs about negative-self in neuroticism was examined.

• Neuroticism was predicted by higher levels of these core beliefs.

• These core beliefs may be involved in negative emotionality of neuroticism.

     

Studies on 145 cases of septicemia in infancy and childhood--especially on septicemic patients with malignant and hematological diseases

Clinical and bacteriological data of 145 inpatients with septicemia, treated at the hospital of Chiba University School of Medicine from 1972 to 1987, were reviewed by dividing them into three stages. (stages I: 1972-76, stage II: 1978-82, stage III: 1983-87) Patients with underlying diseases have been increasing: 91.8% of the total patients in stage III. Among the patients with underlying diseases, malignant and hematological diseases occupied about 60%, and in the other diseases, congenital heart diseases have been increasing in number. As to the organisms isolated, gram positive bacteria have increased, while gram negative bacteria have decreased. In stage III, the rate of gram positive organisms and gram negative ones accounted for 43.1% and 41.2% of all the isolates from the septic patients with malignant & hematological diseases, respectively. In patients with malignant & hematological diseases, alpha-streptococcus, coagulase-negative staphylococcus, and Fusobacterium sp. have been increasing, whereas, Escherichia coli, Enterobacter sp., Klebsiella sp., and Pseudomonas aeruginosa decreasing. In patients with other underlying diseases, S. aureus, CNS, and non Fermenters have been increasing. Among the patients without underlying diseases, gram positive bacteria accounted for the major part. The decrease of gram negative organisms in patients with malignant and hematological diseases may partially depend on the introduction of polymixin B as the drug of gut decontamination. The outcome of septicemia in the patients with malignant & hematological diseases has been markedly improving through all the three stages. During stage III, episode mortality and case mortality rate proved to be 23% and 31%, respectively. The introduction of the third generation cephems has decreased the mortality rate for gram negative organisms and contributed to the improvement of the total prognosis. The prognosis was worst in the case of P. aeruginosa, showing a mortality rate of 50% during stage III. Coincidence rate of blood and other cultures have been largest in the case of P. aeruginosa, so, the drug sensitivity of the strain cultured from other sites is sometimes useful in the choice of antibiotics.     

Three cases of hereditary nonspherocytic hemolytic anemia associated with red blood cell glutathione deficiency

Three unrelated Japanese patients with chronic nonspherocytic hemolytic anemia wer found to have marked deficiency of red blood cell (RBC) reduced glutathoine (GSH) (4.4%, 13.1%, and 6.9% of normal, respectively). A panel of RBC enzyme assays showed that one patient had decreased glutathione synthetase activity and the other two were moderately deficient in gamma-glutamylcystine synthetase. Some family members of each patient showed mild deficiency of the respective enzymes. RBCs of these patients also showed a decreased level of glutathione-S-transferase as in previously described GSH-deficient cases. Hemolytic anemia was their only manifestation, and neither 5- oxoprolinemia nor 5-oxoprolinuria, which are usually associated with to generalized type of glutathione synthetase deficiency, was noted in our patients.     

The Development of Foveolar-type Gastric Adenocarcinoma during Maintenance Therapy of Vonoprazan for Reflux Esophagitis

We herein report the first case of foveolar-type gastric adenocarcinoma that developed after the initiation of vonoprazan (VPZ). A 51-year-old man had heartburn at the first visit and reflux esophagitis endoscopically, so he started taking VPZ. An approximately 5-mm-sized reddish polyp with a raspberry-like morphology was detected at the anterior wall of the upper body of the stomach 156 weeks after starting maintenance therapy with VPZ 10 mg/day. It was diagnosed as foveolar-type gastric adenocarcinoma based on a biopsy. Another approximately 4-mm-sized foveolar-type gastric adenocarcinoma was also detected at the posterior wall of the middle body of the stomach.     

Elastin sub-fraction as binding site for lipids.

Elastin preparations were isolated from human thoracic aorta, from atherosclerotic and from grossly normal regions. A relatively mild procedure was used to avoid hot alkaline extraction and autoclaving. The elastase digest of the aortic elastin was chromatographed on a Sephadex G-100 column and separated into two fractions: A (larger molecular weight) and B (smaller molecular weight). The ratio of fraction A to total aortic elastin increased with age and the development of the atherosclerosis. Amino acid and sugar analyses showed that fraction A consistently contained more polar amino acids, hexose, hexosamine and L-fucose, and less sialic acid, in comparison with fraction B. Part of the elastin preparation was incubated with human low-density lipoprotein; a considerable amount of lipid, especially cholesterol, was transferred from the lipoprotein to the elastin. Estimation of protein and cholesterol in fractions A and B of the elastase hydrolyzate of incubated elastin showed that most of the cholesterol taken up by elastin had been in fraction A. The increased proportion of fraction A in aortic elastin derived from plaque areas appeared responsible for the marked lipid-binding capacity of plaque elastin.     

Argyrophilic proteins of the nucleolar organizer region in acute leukemias and its relation to the S-phase fraction of leukemic cells.

Nucleolar organizer regions (NORs) are loops of DNA which transcribes to ribosomal RNA. The NOR-related protein becomes visible in nucleus by a silver-staining technique under a light microscope, and it has been named argyrophilic protein of NOR (Ag-NOR). In various malignancies, the correlation between the proliferation potential of tumor cells or histological grade and the number of Ag-NORs has been reported. In this study, we investigated the Ag-NOR of acute leukemic cells and its relation to the in vivo proportion of bone marrow leukemic cells in DNA synthetic phase. The number of Ag-NORs in bone marrow leukemic cells was more than that in peripheral blood (means values 2.78 and 2.48, respectively, p less than 0.01). This result shows that the number of Ag-NORs reflects the vigorous proliferative potential of bone marrow leukemic cells. However, no significant correlation was obtained between the number of Ag-NORs and the bromodeoxyuridine-labeling indices (r = 0.2064). These results suggest that Ag-NOR might be one of the markers for cellular proliferation in leukemia, while DNA synthesis of leukemic cells do not seem to be directly related to Ag-NOR. In order to clarify the role of Ag-NOR in leukemia, further studies are needed.     

Dissociation of CCK-8-Induced fluid secretion from protein secretion by ion-transport blockers in rat pancreas

The effects of ion-transport blockers on CCK-8-induced protein output and concomitant fluid secretion were compared in isolated, perfused normal and hypertrophied rat pancreata. In the normal pancreas, perfusion with ouabain (1 mM), amiloride (1 mM), furosemide (1 mM), or SITS (0.1 mM) caused corresponding inhibition of both fluid and protein secretion that was induced by 100 pM CCK-8. Hypertrophy of the pancreas was produced by oral administration of a synthetic protease inhibitor (FOY-305) once a day for 3 wk. In the hypertrophied pancreas, perfusion with ouabain (0.1 or 1 mM) or amiloride (0.1 mM or 1 mM) decreased CCK-8-induced fluid secretion without changing CCK-8-induced protein output. Perfusion with furosemide (1 mM) inhibited both fluid and protein secretion induced by CCK-8, but the amount of inhibition of fluid secretion was much greater than that of protein secretion. Perfusion with SITS (0.1 mM) significantly decreased CCK-8-induced fluid secretion but not protein secretion. These results indicate that in contrast to a normal rat pancreas, the coupling of fluid and protein secretion induced by CCK-8 can be disrupted by experimental procedures that induce hypertrophy in the rat pancreas.     

Low-dose Interferon-α Treatment Improves Survival and Inflammatory Responses in a Mouse Model of Fulminant Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is accompanied by severe lung inflammation induced by various diseases. Despite the severity of symptoms, therapeutic strategies for this pathologic condition are still poorly developed. Interferon (IFN)-α is well known as an antiviral cytokine and low-dose IFN-α has been reported to show antiinflammatory effects. Therefore, we investigated how this cytokine affected ARDS in a mouse model. C57BL/6 mice received sequential intratracheal administration of α-galactosylceramide (α-GalCer) and lipopolysaccharide (LPS), which resulted in the development of fulminant ARDS. These mice were then treated intranasally with IFN-α and their survival, lung weight, pathological findings, and cytokine production were evaluated. Administration of low-dose IFN-α prolonged survival of fulminant ARDS mice, but higher doses of IFN-α did not. Histological analysis showed that low-dose IFN-α treatment improved findings of diffuse alveolar damage in fulminant ARDS mice, which was associated with reduction in the wet/dry (W/D) lung weight ratio. Furthermore, IFN-γ production in the lungs was significantly reduced in IFN-α-treated mice, compared with control mice, but tumor necrosis factor (TNF)-α production was almost equivalent for both groups. Low-dose IFN-α shows antiinflammatory and therapeutic effects in a mouse model of fulminant ARDS, and reduced production of IFN-γ in the lung may be involved in the beneficial effect of this treatment.
