Casein Kinase II Phosphorylation of the Yeast Phospholipid Synthesis Transcription Factor Opi1p*

The transcription factor Opi1p regulates phospholipid synthesis in the yeast Saccharomyces cerevisiae by repressing the expression of several UASINO-containing genes (e.g. INO1). Opi1p repressor activity is most active in inositol-supplemented cells. Regulation of Opi1p repressor activity is mediated by multiple phosphorylations catalyzed by protein kinases A and C. In this work, we showed that Opi1p was also phosphorylated by casein kinase II. Using purified maltose-binding protein-Opi1p as a substrate, casein kinase II activity was doseand time-dependent and dependent on the concentrations of maltosebinding protein-Opi1p (Km = 25 μg/ml) and ATP (Km = 7 μm). Of three mutations (S10A, S38A, and S239A) in putative phosphorylation sites, 10 only the S10A mutation affected Opi1p phosphorylation. That Ser was a specific target of casein kinase II was confirmed by the loss of a phosphopeptide in the S10A mutant protein. The S10A mutation did not affect phosphorylation of Opi1p by either protein kinase A or protein kinase C. Likewise, phosphorylation of Opi1p by casein kinase II was not affected by mutations in protein kinase A (S31A and S251A) and protein S10A kinase C (S26A) phosphorylation sites. Expression of the OPI1 allele in an opi1Δ mutant attenuated (2-fold) the repressive effect of Opi1p on INO1 expression, and this effect was only observed when cells were grown in the absence of inositol. These data supported the conclusion that casein kinase II phosphorylation at Ser10 played a role in stimulating the repression of INO1 when Opi1p was not in its most active state (i.e. in inositol-deprived cells).
Predictors of paradoxical tuberculoma in tuberculous meningitis.

SETTING A tertiary care teaching hospital in Lucknow, India. OBJECTIVE To evaluate the frequency and predictors of paradoxical tuberculoma in definite tuberculous meningitis (TBM) and its influence on TBM outcome. DESIGN Demographic, clinical, biochemical, cerebrospinal fluid (CSF) findings, CD4 counts and magnetic resonance imaging (MRI) findings of 34 patients with definite TBM included were noted. The patients received four-drug anti-tuberculosis treatment and prednisolone. They were followed up clinically and radiologically at 3 and 6 months; serum chemistry, CD4 counts and CSF were tested at 3 months. Functional outcome was defined on the basis of the Barthel index score. Predictors of paradoxical response were evaluated using univariate and multivariate analysis. RESULTS The median age of the patients was 33.5 years; 13 were females. Of the 34 study participants, 22 patients developed paradoxical tuberculoma, mostly within 3 months of initiating anti-tuberculosis treatment. Paradoxical tuberculoma was associated with clinical deterioration in 12 patients. Bacille Calmette-Guérin vaccination, higher CSF glucose and abnormal baseline MRI were associated with paradoxical tuberculoma in univariate analysis. After adjustment of covariates, only female sex was independently associated with paradoxical tuberculoma (OR 0.06, 95%CI 0.004-0.79, P= 0.03). Paradoxical response, however, did not influence 6-month outcome. CONCLUSION Paradoxical tuberculoma occurs in two thirds of patients with definite TBM, and in 50% it is asymptomatic. Females are more susceptible to paradoxical tuberculoma; however, 6-month outcome is not influenced by paradoxical tuberculoma.
Renal and Related Cardiovascular Effects of Conventional and COX-2-Specific NSAIDs and Non-NSAID Analgesics

&NA; On a daily basis it appears that as many as one in five adults in the United States may consume an analgesic compound either on a prescription basis or by over-the-counter (OTC) purchase. This high profile of intermittent or repetitive analgesic use appears to be relatively similar throughout the developed world. Although analgesics generally have a good renal safety profile, the nonsteroidal anti-inflammatory drug (NSAID) analgesics may produce mild renal side effects, such as the generation of peripheral edema in up to 5% of the general population. Other more serious renal and related cardiovascular side effects tend to be more apparent in lesser numbers of clinically “at risk” NSAID analgesic users. In contrast, non-NSAID analgesics, such as paracetamol or tramadol, have essentially no renal or related cardiovascular side effects when used at recommended dosing schedules. This review characterizes the renal syndromes associated with the use of NSAID analgesics, identifies the risks inherent in the use of these compounds in treated patients with hypertension and congestive heart failure, summarizes the early comparable data available for the new COX-2-specific inhibitors, and profiles the scant acute and long-term clinical concerns attendant with the use of non-NSAID nonnarcotic analgesics. It is important that healthcare providers and practitioners are aware of the relative renal risks of different analgesics and that they use this knowledge to counsel the analgesic-consuming population appropriately.
Elderly peoples' meals. A comparative study between elderly living in a nursing home and frail, self-managing elderly.

BACKGROUND Sweden is one of few countries that have specific recommendations regarding mealtime habits. The importance of mealtime habits for health outcome is inadequately studied in elderly subjects. OBJECTIVE The aim of this study was to investigate the distribution of the daily meals/energy intake; the number of eating episodes per day and subjectively estimated meal-dependent variables (appetite, motivation to eat, sense of taste and sense of smell) and compare the results of elderly living in a nursing home with frail, self-managing elderly living at home. DESIGN Explorative study. All analyses of energy intake were based on food records; weighed in the nursing home and estimated in the frail, self-managing elderly. Participants or contact persons estimated the subjective variables using a 10-point VAS scale. RESULTS On average there were 4-5 daily eating episodes in both groups. The eating episodes were much more widespread over the day in the self-managing elderly, and their length of fasting at night was significantly shorter. The subjects estimated appetite and sense of smell was reduced in about 30-40% in both groups. Sense of taste was reduced in 40 % of the males and 10-20 % of the females. Energy intake was similar in both groups, 25 kcal/kg body weight/day, with more than a threefold variation among individual subjects. Energy intake/kg body weight correlated with a shorter length of fasting at night in the nursing home residents, however, did not correlate with ADL, number of eating episodes per day, appetite, motivation to eat, or senses of taste or smell. CONCLUSION The self-managing elderly had more widespread eating episodes than the elderly in the nursing home, indicating that self-managing elderly exhibit larger variations in food intake preferences, however, without affecting mean energy intake. The lack of correlation between energy intake and estimated appetite, taste and smell is in line with previous findings in elderly.
Influence of Precursors and Inhibitor on the Production of Extracellular 5-Aminolevulinic Acid and Biomass by Rhodopseudomonas palustris KG31

5-Aminolevulinic acid (ALA) and the biomass of photosynthetic bacteria, Rhodopseudomonas palustris KG31, have very high potential for development and exploitation as bioherbicide and biofertilizer respectively. In this work, the effects of two precursors and an inhibitor of aminolevulinic dehydratase (ALAD) added to the VFA culture medium on the production of ALA and biomass were investigated. The experimental runs were carried out according to a Box-Behnken design. The precursors were added to the medium at the beginning of cultivation, while the inhibitor was added after 24 h. Statistical analysis indicated that levulinic acid (LA) has a positive effect on ALA production while glycine has a negative effect on biomass production. In order to enhance both ALA and biomass products, the most suitable medium was VFA medium supplemented with 3.0 mM glycine and 10 mM LA, giving ALA and biomass of 182.91 μM and 3.1 gDCW/l within 54 h.
Serum insulin levels, 24-hour blood pressure profile, and left ventricular mass in nonobese hypertensive patients.

In essential hypertensive patients, considered to be insulin-resistant, a blunted decline in nocturnal blood pressure is associated with increased adrenergic tone and left ventricular mass. Since insulin stimulates the sympathetic system, we tested whether insulin resistance and insulinemia influence left ventricular mass and the 24-hour blood pressure profile. We studied 29 nonobese hypertensive patients with office diastolic pressure between 95 and 110 mm Hg and normal oral glucose tolerance test after a 4-month washout period. They were then assigned to M-mode echocardiographic evaluation and 24-hour ambulatory blood pressure monitoring. The glucose and insulin responses to a 75-g oral glucose load were compared with those obtained in 16 weight-matched normotensive control subjects. During the oral glucose tolerance test the hypertensive patients compared with control subjects presented higher levels of glucose at 60 minutes (138.7 +/- 30.3 versus 108.7 +/- 35.7 mg/dL; P < .05) and 90 minutes (114.0 +/- 23.8 versus 94.8 +/- 31.1 mg/dL; P < .05) and insulin at 60 minutes (287.1 +/- 259.4 versus 142.1 +/- 83.9 pmol/L; P < .05). However, peak insulin levels after glucose load did not correlate with ambulatory blood pressure values or left ventricular mass index. Left ventricular mass index showed significant correlation with mean sleeping systolic pressure (rs = 56, P < .05) and diurnal systolic pressure (rs = .37, P < .05) but not with mean diurnal or sleeping diastolic pressures. In conclusion, our results indicate that in nonobese hypertensive patients, insulin resistance does not have any influence on the 24-hour blood pressure profile or on left ventricular mass index.

Recent developments in steroid-responsive pancreatitides (autoimmune pancreatitis)

Purpose of review There are two distinct steroid responsive chronic fibro-inflammatory diseases of the pancreas, called type 1 and type 2 autoimmune pancreatitis (AIP). We review recent progress in this field. Recent findings It has recently been suggested that the term AIP be used to describe type 1 AIP and the term idiopathic duct-centric chronic pancreatitis (IDCP) be used for type 2 AIP. Clinical features and long-term outcomes of AIP and IDCP are well characterized and prognosis of both diseases is excellent. Diagnostic strategies tailored to regional practice patterns have emerged with the application of International Consensus Diagnostic Criteria for AIP. Although corticosteroids remain the mainstay of treatment, management of relapses and strategies for preventing multiple relapses are better understood, including the role of maintenance therapy and B-cell depletion therapy with rituximab. Association studies with malignancies have yielded conflicting results regarding risk of cancer in AIP. Summary The treatment, follow-up guidelines and associations continue to evolve with our increasing experience with both AIP and IDCP. In AIP, rituximab can be used for both induction and maintenance of remission. IDCP responds to steroids without need for maintenance therapy. Both AIP and IDCP have excellent prognosis.
The relations between physical ability and bone mass in women aged over 65 years

In this cross‐sectional study of 55 women (mean age 73.54 ± 5.87), the magnitude of the relation between different indices of physical ability and confounding factors to bone density were determined. Physical fitness was assessed by direct measurement of maximal oxygen consumption (V̇O2 max), isokinetic muscle strength, and quadriceps and psoas muscle surfaces and densities using computed tomography. Anthropometry, chronological and gynecological ages, and dietary calcium intake were also recorded. The bone mineral density (BMD) was evaluated at the axial level (lumbar spine and proximal femur) and at the peripheral level (radius and tibia, cancellous and cortical compartments). Parameters related to physical ability proved to be the best predictors of BMD in radial and tibial cancellous compartments, spine, femoral neck, and trochanter, accounting for 15–27.5% of the total variance. The V̇O2 max was a major determinant of the femoral mineral density and one of the predictors of radial and tibial cancellous compartments. Psoas parameters were strongly related to spine mineral density and also constituted a predictor of radius (cancellous) and tibia mineral densities. The arm muscle strength could predict, though weakly, the BMD of axial skeleton, whereas thigh muscle strength only predicted the BMD of inferior limbs. No correlation was observed between current dietary calcium intake and BMD. Age‐postmenopause and fertile life remained predictive of BMD at mostly cancellous sites, whereas anthropometry exerted important effects on radial and tibial cortices. The study suggests distinct sets of relations between physical ability and the BMD variables. Subjects with greater and denser psoas muscles had greater spine BMD, and those with higher V̇O2 max had greater proximal femur BMD.
Molecular Analysis of Pediatric Oligodendrogliomas Highlights Genetic Differences with Adult Counterparts and Other Pediatric Gliomas

Oligodendroglioma represents a distinctive neoplasm in adults but similar neoplasms occur rarely in children. We studied 20 cases of pediatric oligodendroglioma by SNP array (median age 9 years, range 1–19; 15 grade II and 5 grade III). Cytogenetic abnormalities were present in 8 (53%) grade II and all five anaplastic oligodendrogliomas. Most changes were in the form of deletion and copy neutral loss of heterozygosity (LOH). The most common abnormality was 1p deletion (n = 5). Whole arm 1p19q co‐deletion was present in three cases from adolescent patients and 9p loss in 3, including one low‐grade oligodendroglioma with CDKN2A homozygous deletion. Common losses were largely limited to the anaplastic subset (n = 5) and included 3q29 (n = 3), 11p (n = 3), 17q (n = 3), 4q (n = 2), 6p (n = 2), 13q (n = 2), 14q (n = 2), 17p (n = 2) and whole Ch 18 loss (n = 2). Gains were non‐recurrent except for whole Ch 7 (n = 2) and gain on 12q (n = 2) including the MDM2 locus. Possible germ line LOH (or uniparental disomy) was present in seven cases (35%), with one focal abnormality (22q13.1‐13.2) in two. BRAF‐KIAA1549 fusions and BRAF p.V600E mutations were absent (n = 13 and 8). In summary, cytogenetic alterations in pediatric oligodendrogliomas are characterized mostly by genomic losses, particularly in anaplastic tumors.
Effects of Pretest Stimulative and Sedative Music on Grip Strength

The purpose of the present study was to investigate the effects of stimulative (energizing) and sedative (relaxing) music on grip strength. A 2 × 3 (gender × condition) repeated-measures analysis of variance and post hoc tests showed that participants (N = 50) evidenced higher grip strength after listening to stimulative music (M = 43.94 kg. force) than after sedative music or a white noise control condition. Sedative music yielded lower scores than white noise. Men evidenced higher grip strength than women, but there was no interaction between gender and music condition. It was concluded that a simple motoric task such as grip strength provides a sensitive measure of psychophysical responses to music.
Psoriasis plaque test with confocal microscopy: evaluation of different microscopic response pathways in NSAID and steroid treated lesions

Pathophysiology of psoriasis is complex and characterized by microscopic, specific changes. In vivo reflectance confocal microscopy (RCM) provides tissue and cell morphology information in non‐invasive way, generating quasi‐histologic resolution. Concerning plaque psoriasis, confocal criteria have been described disclosing high agreement between RCM and conventional histology.
Sox10 directs neural stem cells toward the oligodendrocyte lineage by decreasing Suppressor of Fused expression

Oligodendrocyte precursor cells (OPCs) are lineage-restricted progenitors generally limited in vivo to producing oligodendrocytes. Mechanisms controlling genesis of OPCs are of interest because of their importance in myelin development and their potential for regenerative therapies in multiple sclerosis and dysmyelinating syndromes. We show here that the SoxE transcription factors (comprising Sox8, 9, and 10) induce multipotent neural precursor cells (NPCs) from the early postnatal subventricular zone (SVZ) to become OPCs in an autonomous manner. We performed a chromatin immunoprecipitation-based bioinformatic screen and identified Suppressor of Fused (Sufu) as a direct target of repression by Sox10. In vitro, overexpression of Sufu blocked OPC production, whereas RNAi-mediated inhibition augmented OPC production. Furthermore, mice heterozygous for Sufu have increased numbers of OPCs in the telencephalon during development. We conclude that Sox10 acts to restrict the potential of NPCs toward the oligodendrocyte lineage in part by regulating the expression of Sufu.
Classification of cesarean sections among immigrants in Belgium

Objective. To provide insight into the differential effect of immigration on cesarean section (CS) rates, using the Robson classification. Design. A population‐based study using birth certificates from the birth registry of 2009. Setting. All births in two of the three Belgian regions excluding Flanders. Population. 37 628 deliveries from Belgian and immigrant mothers from sub‐Saharan Africa, Maghreb and Eastern Europe. Methods. Multivariate analyses using CS as the dependent variable and immigration status as the primary independent variable. Several multivariate logistic regression models were built including medical, anthropometric, socio‐economic characteristics, and medical interventions. The impact of analyzing all delivery sites together was tested using mixed‐effect analyses. Main outcome measures. CSs of immigrant subgroups compared with Belgian women. Results. CS rates varied according to immigrant subgroups. Mothers from sub‐Saharan Africa had an adjusted odds ratio of 2.06 (1.62–2.63) for CS compared with Belgian natives. Increased risk for mothers from sub‐Saharan Africa compared with Belgian natives was found among nulliparous and multiparous women without previous CS, and a term, singleton fetus in cephalic position. In comparison, nulliparous East European mothers with a term singleton fetus in cephalic position in spontaneous labor had an adjusted odds ratio of 0.29 (0.08–0.99) for CS. Conclusions. CS rates currently vary between Robson categories in immigrant subgroups. Immigrant mothers from sub‐Saharan Africa with a term, singleton infant in cephalic position, without previous CS, appear to carry the highest burden.
Computational Substrates of Norms and Their Violations during Social Exchange

Social norms in humans constrain individual behaviors to establish shared expectations within a social group. Previous work has probed social norm violations and the feelings that such violations engender; however, a computational rendering of the underlying neural and emotional responses has been lacking. We probed norm violations using a two-party, repeated fairness game (ultimatum game) where proposers offer a split of a monetary resource to a responder who either accepts or rejects the offer. Using a norm-training paradigm where subject groups are preadapted to either high or low offers, we demonstrate that unpredictable shifts in expected offers creates a difference in rejection rates exhibited by the two responder groups for otherwise identical offers. We constructed an ideal observer model that identified neural correlates of norm prediction errors in the ventral striatum and anterior insula, regions that also showed strong responses to variance-prediction errors generated by the same model. Subjective feelings about offers correlated with these norm prediction errors, and the two signals displayed overlapping, but not identical, neural correlates in striatum, insula, and medial orbitofrontal cortex. These results provide evidence for the hypothesis that responses in anterior insula can encode information about social norm violations that correlate with changes in overt behavior (changes in rejection rates). Together, these results demonstrate that the brain regions involved in reward prediction and risk prediction are also recruited in signaling social norm violations.
Regulation of the EDG84A gene by FTZ-F1 during metamorphosis in Drosophila melanogaster

The transcription factor FTZ-F1 is a member of the nuclear hormone receptor superfamily and is transiently expressed during the mid- and late prepupal periods in Drosophila melanogaster. A putative pupal cuticle gene, EDG84A, is expressed slightly following FTZ-F1 expression during the prepupal period and carries a strong FTZ-F1 binding site between bases 100 and 92 upstream of its transcription start site. In this study, EDG84A mRNA was found to be prematurely expressed upon heat induction of FTZ-F1 in prepupae carrying the heat shock promoter-FTZ-F1 cDNA fusion gene construct. Transgenic fly lines having the 0.8-kb region of the EDG84A promoter fused to lacZ expressed the reporter gene in a tissue- and stage-specific manner. Base substitutions in the FTZ-F1 binding site within the 0.8-kb promoter abolished expression of lacZ. These results strongly suggest that the EDG84A gene is a direct target of FTZ-F1. Deletion studies of the cis-regulatory region of the EDG84A gene revealed that space-specific expression in imaginal disc-derived epidermis is controlled by the region between bp -408 and -104 from the transcription start site. The region between bp -408 and -194 is necessary to repress expression in a posterior part of the body, while the region between bp -193 and -104 carries a positive element for activation in an anterior part of the body. These results suggest that FTZ-F1 governs expression of the EDG84A gene in conjunction with putative tissue-specific regulators.
Stability of Salt Double-Fortified with Ferrous Fumarate and Potassium Iodate Or Iodide under Storage and Distribution Conditions in Kenya

The stability of table salt double-fortified with iron as ferrous fumarate, and with iodine as potassium iodide or potassium iodate, has been investigated under actual field conditions of storage and distribution in the coastal and highland regions of Kenya. Seven 200-g sample packets of double-fortified salt in sealed polyethylene bags and a similar packet containing a datalogger for monitoring temperature and humidity were packaged with 21 sample bags of salt from another study into a bundle, which then entered the distribution network from a salt manufacturer's facility to the consumer. Iodine retention values of up to 90% or more were obtained during the three-month study. Double-fortified salt was prepared using ferrous fumarate microencapsulated with a combination of binders and coloring agents and coated with soy stearine, in combination with either iodated salt or salt iodized with potassium iodide microencapsulated with dextrin and coated with soy stearine. Most of the ferrous iron was retained, with less than 17% being oxidized to the ferric state. The polyethylene film overwrap of salt packs in the bundles provided significant protection from ambient humidity. Salt double-fortified with iodine and microencapsulated iron ferrous fumarate premix was generally quite stable, because both iodine and ferrous iron were protected during distribution and retail in typical tropical conditions in Kenya's highlands and humid lowlands.
