Gallows humor for a scaffold setting: managing aggressive patients on a maximum-security forensic unit.

Gallows humor, as depicted in television shows such as MASH and Hill Street Blues, fulfills important psychological and sociological functions in maintaining therapeutic attitudes in the stressful and sometimes dangerous milieu of a maximum-security psychiatric unit. Humor provides an emotional language with which the unit's staff mark the sense of incongruity that characterizes their work. Staff invoke humor to move away from a macho attitude in their interactions with aggressive patients. Humor also bolsters staff solidarity through playful inversions of the usual patterns of authority.

Behavior-change trials to assess the feasibility of improving complementary feeding practices and micronutrient intake of infants in rural Bangladesh.

This study used simple rapid-assessment techniques to test the feasibility of increasing the consumption of complementary foods by infants by asking mothers to increase meal quantity or frequency or by altering the viscosity/energy density of the food. The feasibility of using micronutrient supplements either added directly to food or administered as liquid drops was also examined. The study was conducted in rural Bangladesh and involved four separate short-term behavioral change trials. Depending on the trial, fieldworkers recruited 30 to 45 infants 6 to 12 months of age. Following recommendations to increase the amount of food provided to infants, the mean intakes from single meals increased from 40 +/- 23 g on day 1 to 64 +/- 30 g on day 7 (p < 0.05). In a second trial, the mean meal frequency increased from 2.2 +/- 1.3 on day 1 to 4.1 +/- 1.3 on day 7 (p < 0.05). Provision of high-energy-density diets, prepared by decreasing viscosity with alpha-amylase or by hand-mashing rice and dhal into a paste before feeding, increased single-meal energy consumption from 54 +/- 35 kcal to 79 +/- 52 kcal or 75 +/- 37 kcal (p < 0.05), respectively. Both types of micronutrient supplements were well accepted and used according to recommendations. In conclusion, it was possible to change short-term child-feeding behaviors to promote increased food intake, mealfrequency, energy density, and micronutrient consumption. Because each of these interventions lasted for only about 1 week, however, the long-term sustainability of these changes is not known. Moreover, the effect of increased feeding of complementary foods on intakes of breastmilk and total daily consumption of energy and nutrients requires further study.

Food selection associated with sense of coherence in adults.

BACKGROUND: Favorable dietary habits promote health, whereas unfavorable habits link to various chronic diseases. An individual's "sense of coherence" (SOC) is reported to correlate with prevalence of some diseases to which dietary habits are linked. However, understanding what determines an individual's dietary preferences and how to change his/her behavior remains limited. The aim of the present study was to evaluate associations between dietary intake and SOC in adults. METHODS: Diet intake was recorded by an 84-item semi-quantitative food frequency questionnaire and SOC was measured by the 13-item Antonovsky questionnaire in 2,446 men and 2,545 women (25-74 years old) from the population based northern Sweden MONICA screening in 1999. RESULTS: Intakes of energy, total and saturated fat, ascorbic acid, sucrose, and servings of fruits, vegetables, cereals, and sweets correlated with SOC among women, whereas intakes of total and saturated fat, ascorbic acid, fiber, and alcohol, and servings of fruits, vegetables, bread, bread and cereals, fish, and potatoes correlated with SOC among men. With a few exceptions, intakes of these nutrients/foods were significantly explained by SOC quartile scores in linear GLM models. Both women and men classified into the highest SOC quartile had significantly higher age-BMI-education standardized mean intakes of vegetables than those in the lowest quartiles. Women in the highest SOC quartile also had higher intake of fruits but lower intakes of energy, total and saturated fat, sucrose, and sweets. Projection to latent structures (PLS) multivariate modeling of intakes of the 84 food items and food aggregates simultaneously on SOC scores supported low SOC to coincide with a presumably less health promoting dietary preference, e.g. intake of pizza, soft drinks, candies, sausages for main course, hamburgers, mashed potato, chips and other snacks, potato salad, French fries, whereas men and women with high SOC scores were characterized by e.g. high intake of rye crisp whole meal bread, boiled potato, vegetables, berries, and fruits. CONCLUSION: Both men and women in the highest, as compared with the lowest, SOC score quartile reported more "healthy" food choices. Dietary habits for individuals in the lowest SOC quartile therefore may render a higher risk for various endemic diseases.

Convergent and discriminant validity of measures of parenting efficacy and control.

Examined the convergent and discriminant validity of the Parent Attribution Test (PAT; Bugental, Blue, & Cruzcosa, 1989), the Parental Locus of Control Scale (PLOC; Campis, Lyman, & Prentice-Dunn, 1986), and the Parenting Sense of Competence-Efficacy Scale (PSOC-Efficacy; Johnston & Mash, 1989) in 3 samples of community mothers. In the 1st 2 samples, mothers also completed measures of negative affect and social desirability. In the 3rd sample, the PAT and PSOC-Efficacy scales were administered with measures of adult attachment style and child behavior problems. There was weak support for the convergent validity of the measures. Moreover, the discriminant validity of the measures was not adequately demonstrated. Our results suggest that PLOC and PSOC-Efficacy scores may reflect distress and response style as well as beliefs about parenting. Scores on the PAT, although less influenced by response style and distress, appear to reflect a different dimension of efficacy than that assessed by other self-report measures.

Evidence-based assessment of autism spectrum disorders in children and adolescents.

This article reviews evidence-based criteria that can guide practitioners in the selection, use, and interpretation of assessment tools for autism spectrum disorders (ASD). As Mash and Hunsley (2005) discuss in this special section, evidence-based assessment tools not only demonstrate adequate psychometric qualities, but also have relevance to the delivery of services to individuals with the disorder (see also Hayes, Nelson, & Jarrett, 1987). Thus, we use what is known about the symptoms, etiologies, developmental course, and outcome of ASD to evaluate the utility of particular assessment strategies and instruments for diagnosis, treatment planning and monitoring, and evaluation of outcome. The article begins with a review of relevant research on ASD. Next we provide an overview of the assessment process and some important issues that must be considered. We then describe the components of a core (minimum) assessment battery, followed by additional domains that might be considered in a more comprehensive assessment. Domains covered include core autism symptomatology, intelligence, language, adaptive behavior, neuropsychological functions, comorbid psychiatric illnesses, and contextual factors (e.g., parent well-being, family functioning, quality of life). We end with a discussion of how well the extant literature meets criteria for evidence-based assessments.

Conservation of the Notch signalling pathway in mammalian neurogenesis.

The Notch pathway functions in multiple cell fate determination processes in invertebrate embryos, including the decision between the neuroblast and epidermoblast lineages in Drosophila. In the mouse, targeted mutation of the Notch pathway genes Notch1 and RBP-Jk has demonstrated a role for these genes in somite segmentation, but a function in neurogenesis and in cell fate decisions has not been shown. Here we show that these mutations lead to altered expression of the Notch signalling pathway homologues Hes-5, Mash-1 and Dll1, resulting in enhanced neurogenesis. Precocious neuronal differentiation is indicated by the expanded expression domains of Math4A, neuroD and NSCL-1. The RBP-Jk mutation has stronger effects on expression of these genes than does the Notch1 mutation, consistent with functional redundancy of Notch genes in neurogenesis. Our results demonstrate conservation of the Notch pathway and its regulatory mechanisms from fly to mouse, and support a role for the murine Notch signalling pathway in the regulation of neural stem cell differentiation.

Early specification of sensory neuron fate revealed by expression and function of neurogenins in the chick embryo.

The generation of sensory and autonomic neurons from the neural crest requires the functions of two classes of basic helix-loop-helix (bHLH) transcription factors, the Neurogenins (NGNs) and MASH-1, respectively (Fode, C., Gradwohl, G., Morin, X., Dierich, A., LeMeur, M., Goridis, C. and Guillemot, F. (1998) Neuron 20, 483-494; Guillemot, F., Lo, L.-C., Johnson, J. E., Auerbach, A., Anderson, D. J. and Joyner, A. L. (1993) Cell 75, 463-476; Ma, Q., Chen, Z. F., Barrantes, I. B., de la Pompa, J. L. and Anderson, D. J. (1998 Neuron 20, 469-482). We have cloned two chick NGNs and found that they are expressed in a subset of neural crest cells early in their migration. Ectopic expression of the NGNs in vivo biases migrating neural crest cells to localize in the sensory ganglia, and induces the expression of sensory neuron-appropriate markers in non-sensory crest derivatives. Surprisingly, the NGNs can also induce the expression of multiple pan-neuronal and sensory-specific markers in the dermomyotome, a mesodermal derivative. Taken together, these data suggest that a subset of neural crest cells may already be specified for a sensory neuron fate early in migration, as a consequence of NGN expression.

TGFbeta/BMP activate the smooth muscle/bone differentiation programs in mesoangioblasts.

Mesoangioblasts are vessel-derived stem cells that can be induced to differentiate into different cell types of the mesoderm such as muscle and bone. The gene expression profile of four clonal derived lines of mesoangioblasts was determined by DNA micro-array analysis: it was similar in the four lines but different from 10T1/2 embryonic fibroblasts, used as comparison. Many known genes expressed by mesoangioblasts belong to response pathways to developmental signalling molecules, such as Wnt or TGFbeta/BMP. Interestingly, mesoangioblasts express receptors of the TGFbeta/BMP family and several Smads and, accordingly, differentiate very efficiently into smooth muscle cells in response to TGFbeta and into osteoblasts in response to BMP. In addition, insulin signalling promotes adipogenic differentiation, possibly through the activation of IGF-R. Several Wnts and Frizzled, Dishevelled and Tcfs are expressed, suggesting the existence of an autocrine loop for proliferation and indeed, forced expression of Frzb-1 inhibits cell division. Mesoangioblasts also express many neuro-ectodermal genes and yet undergo only abortive neurogenesis, even after forced expression of neurogenin 1 or 2, MASH or NeuroD. Finally, mesoangioblasts express several pro-inflammatory genes, cytokines and cytokine receptors, which may explain their ability to be recruited by tissue inflammation. Our data define a unique phenotype for mesoangioblasts, explain several of their biological features and set the basis for future functional studies on the role of these cells in tissue histogenesis and repair.

[Effects of bile and meal on the gastrointestinal absorption of 2-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)-1H-pyrazolo[3,4-b]pyridin- 1-yl]ethyl acetate, a new non-steroidal anti-inflammatory agent].

The effects of bile and meal on the gastrointestinal absorption of 2-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)-1H-pyrazolo[3,4-b]pyridin - 1-yl]ethyl acetate (1), were investigated in rats and dogs. Compound 1 was lipophilic and soluble in bile, but extremely insoluble in water. The important role of bile in the dissolution step in the absorption process of 1 was confirmed on the in situ absorption study with rats. Oral absorption of 1 was insufficient and showed a marked individual difference in fasting dogs. When the same compound was administered after ingestion of a meal, the absorption increased with decreasing scatter. Three kinds of meals had different potencies to enhance the bio-availability of 1 in the order of lard greater than mashed potatoes greater than skimmed milk. The absorption behavior of 1 reflected small intestinal transit time and the stimulated bile output after ingestion of meal.

Rice protein digestion by sake koji enzymes: comparison between steamed rice grains and isolated protein bodies from rice endosperm.

The digestion of proteins in steamed rice grains by sake koji enzymes under simulated sake mash conditions was analyzed by comparing the hydrolysis of steamed rice grains and heat-treated protein bodies (PBs) isolated from seven rice samples including four endosperm-storage protein mutants. The disappearance of peptides in the digest of isolated PBs was faster than that of steamed rice grains; however, more insoluble proteins formed in the case of isolated PBs. Not all of the hydrolyzed PB proteins were immediately solubilized in the digestion tests. High-molecular-weight peptides were more abundant in the solubilized digest of steamed rice grains than in that of isolated PBs. Variance in Ile, Ser, Glu, and Gly levels in the digest of steamed rice grains was relatively high among the seven samples, but was not found to be high in digests of isolated PBs. These results indicate that factors that may be derived from the steamed rice grains profoundly affect the digestion of proteins in steamed rice grains by sake koji enzymes.

Different missense mutations in PDR1 and PDR3 genes from clotrimazole-resistant sake yeast are responsible for pleiotropic drug resistance and improved fermentative activity.

Series of gain-of-function missense mutations in PDR1 and PDR3 that encode transcription factors are known to increase the expression of ABC transporters that extrude various kinds of drugs out of a cell, leading to pleiotropic drug resistance (PDR). Previously, the PDR1-H176 (L309S) allele from a clotrimazole (CTZ)-resistant sake yeast mutant has been cloned and found to be sufficient to confer PDR and improved fermentative activity on the arginase-deficient (car1/car1) sake yeast HL163. In this study, another PDR1 and three PDR3 a!leles were cloned from other CTZ-resistant mutants. These alleles contain different missense mutations, PDR1-2 (M308I), PDR3-C21 (L950S), PDR3-C231 (G948D), and PDR3-11 (G957D). The gene recombinants containing each of the mutations found in CTZ-resistant mutants were constructed using the wild-type sake yeast K1001. The gene recombination was designed to generate only a nucleotide replacement without any other DNA changes such as insertion of external DNA fragments. The resultant recombinants that were heterozygous for each of the mutations showed various degrees of drug resistance that were comparable to those of the CTZ-resistant mutants. The recombinants, except one introduced with PDR1-H176, also fermented sake mash faster and produced higher amounts of alcohol than K1001 did. These results demonstrated that PDR1-2, PDR3-C21, PDR3-C231, and PDR3-11 are sufficient to confer PDR and improved fermentative activity on K1001, and suggested that previous results in which fermentative activity of HL163 was significantly improved by PDR1-H176 must have depended on its genetic background, probably arginase deficiency.

Effect of amino acids on peptide transport in sake yeast.

The PTR 2 gene of Saccharomyces cerevisiae encodes a major peptide permease responsible for the uptake of low-molecular-weight peptides consisting of two or three amino acids. We show that the PTR 2 gene of sake yeast encodes a major peptide permease in the main mash of sake brewing. The peptide uptake activity in sake yeast is decreased by the addition of certain types of amino acids, particularly asparagine, serine and lysine. Northern blot analysis suggested that asparagine and serine repress the expression of the PTR 2 gene, but lysine decreases the peptide transport activity without repressing PTR 2 gene transcription. The deletion analysis of the PTR 2 promoter region confirmed these suggestions and revealed that the cis-element involved in the regulation of the PTR 2 gene by amino acids is located in the region from residue --400 to the start codon.

Synthesis of alpha-D-glucosylglycerol by alpha-glucosidase and some of its characteristics.

It has been found that alpha-D-glucosylglycerol (GG) is contained in such traditional Japanese foods brewed by using koji as sake, miso and mirin, and that GG is formed by transglucosylation to glycerol that is produced by yeast with alpha-glucosidase (EC 3.2.1.20) from koji in the sake mash. GG has also been found to consist of three components, 2-O-alpha-D-glucosylglycerol (GG-II), (2R)-1-O-alpha-D-glucosylglycerol (R-GG-I) and (2S)-1-O-alpha-D-glucosylglycerol (S-GG-I). GG was synthesized from a mixture of maltose and glycerol by the batch method, using alpha-glucosidase (transglucosidase L-AMANO). alpha-Glucosidase seemed to be so stable that the amount of GG increased about 5-fold compared with that in the first reaction by the daily addition of maltose for 10 d. Syrupy GG obtained was found to have the following characteristics: about 0.55-fold sweetness compared with sucrose, high thermo-stability, low heat-colorability, low Maillard reactivity, low hygroscopicity, high water-holding capacity, non-cariogenicity and low digestibility.

Identification of alpha-D-glucosylglycerol in sake.

alpha-D-Glucosylglycerol (GG) was found for the first time in sake (Japanese rice wine) in an amount of about 0.5%. GG was also found in miso and mirin which had been brewed by using koji. GG was hydrolyzed into glucose and glycerol in an equimolar ratio with maltase (EC 3.2.1.20, alpha-glucosidase from yeast), but not with emulsin (EC 3.2.1.21, beta-glucosidase from almond). The retention times and mass spectra of trimethylsilyl derivatives by a GC-MS analysis of GG in sake were comparable to those of various GG samples synthesized by glycol cleavage. It was proven that GG in sake consisted of three components, viz., 2-O-alpha-D-glucosyl-glycerol (GG-II), (2R)-1-O-alpha-D-glucosylglycerol (R-GG-I) and (2S)-1-O-alpha-D-glucosylglycerol (S-GG-I). The ratio of the three components in GG was 6:66:28 for sake. It is considered that GG was formed by transglucosylation of the glucosyl groups to glycerol by alpha-glucosidase from koji in the sake mash.

Regional risk factors for stomach cancer in the FRG.

A multicentric, hospital-based, case-control study was conducted in high- and low-risk areas for stomach cancer in the Federal Republic of Germany, by which means a low intake of dietary vitamin C (relative risk [RR] = 2.32, 95% confidence interval [CI] 1.22-4.43 for lowest against highest quintile), noncentralized water supply (RR = 2.17, CI 1.14-4.13 against central water supply), refrigerator use for less than 25 years (RR = 1.33, CI 0.82-2.15 against more than 30 years), and the use of spruce for smoking meat at home (RR = 3.33, CI 1.56-7.12 against not smoking meat at home), were identified as factors potentially causally related to stomach cancer occurrence. The attributable risk for gastric carcinoma among the population (AR) was 37.5% for low vitamin C intake, 37.2% for noncentralized water supply, 10.6% for late refrigerator use, and 4.15% for use of spruce for smoking meat at home in this analysis. The overall ARp amounted to 68.3%. These personally linked factors also showed a strong regional distribution, in that the low-risk area had more favorable categories of exposure. Traditional nutritional habits around 1910 were recorded during a survey by ethnologists in 1965. This material was used to contrast those in high and low stomach cancer risk areas with the habits in the south of Germany in general. Vegetable use was most common in the low-risk area, whereas mashed potatoes, cabbage, and farinaceous dishes dominated in the high-risk area. Tomatoes were introduced several years later into the high-risk area, both in terms of consumption and cultivation.(ABSTRACT TRUNCATED AT 250 WORDS)

Significance of proneural basic helix-loop-helix transcription factors in neuroendocrine differentiation of fetal lung epithelial cells and lung carcinoma cells.

In this brief review article, we describe how cell fate determination by which the airway epithelial cells become neuroendocrine or non-neuroendocrine is regulated by a network of basic helix-loop-helix transcription (bHLH) factors in a similar manner to neuronal differentiation, and how this system could work to determine cell differentiation of human lung carcinomas. Immunohistochemical studies reveal that mammalina achaete-scute complex homologue (Mash)1 is expressed in pulmonary neuroendocrine cells (PNEC), while hairy and Enhancer of split (Hes)1 is expressed in pulmonary non-neuroendocrine cells (non-PNEC). Studies using gene-deficient mice for the bHLH factors revealed that in Mash1 homozygous null mice no PNEC are detected, while PNEC increase markedly in Hes1 homozygous null mice. These observations suggest that Mash1 is an essential positive factor for neuroendocrine differentiation of lung epithelium, and that Hes1 is one of the repressive factors for neuroendocrine differentiation. Moreover, immunohistochemical studies revealed that Notch receptors are detected in non-PNEC, and thus the Notch signalling pathway could play a role in the determination of airway epithelial cell differentiation. In human lung carcinomas, a similar bHLH network should operate to determine cell differentiation phenotypes. Generally, expression of the human homologue of Mash1 (HASH1) is detected in small cell carcinoma and carcinoids, while Hes1 seems to be expressed mainly in non-small cell carcinoma. Thus, proneuronal bHLH factors may play roles in cell fate determination of the airway epithelial system, and may regulate human airway epithelial cells in diseased conditions.

Molecular interaction between projection neuron precursors and invading interneurons via stromal-derived factor 1 (CXCL12)/CXCR4 signaling in the cortical subventricular zone/intermediate zone.

Most cortical interneurons are generated in the subpallial ganglionic eminences and migrate tangentially to their final destinations in the neocortex. Within the cortex, interneurons follow mainly stereotype routes in the subventricular zone/intermediate zone (SVZ/IZ) and in the marginal zone. It has been suggested that interactions between invading interneurons and locally generated projection neurons are implicated in the temporal and spatial regulation of the invasion process. However, so far experimental evidence for such interactions is lacking. We show here that the chemokine stromal-derived factor 1 (SDF-1; CXCL12) is expressed in the main invasion route for cortical interneurons in the SVZ/IZ. Most SDF-1-positive cells are proliferating and express the homeodomain transcription factors Cux1 and Cux2. Using MASH-1 mutant mice in concert with the interneuron marker DLX, we exclude that interneurons themselves produce the chemokine in an autocrine manner. We conclude that the SDF-1-expressing cell population represents the precursors of projection neurons during their transition and amplification in the SVZ/IZ. Using mice lacking the SDF-1 receptor CXCR4 or Pax6, we demonstrate that SDF-1 expression in the cortical SVZ/IZ is essential for recognition of this pathway by interneurons. These results represent the first evidence for a molecular interaction between precursors of projection neurons and invading interneurons during corticogenesis.
