Opioid peptides are well-known modulators of the central control of reproduction. Among them, dynorphin coexpressed in kisspeptin (KP) neurons of the arcuate nucleus (ARC) has been thoroughly studied for its autocrine effect on KP release through $\kappa$ opioid receptors. Other studies have suggested a role for $\beta$-endorphin (BEND), a peptide cleaved from the proopiomelanocortin (POMC) precursor, on food intake and central control of reproduction. Similarly to KP, BEND content in the ARC of sheep is modulated by day length and BEND modulates food intake in a dose-dependent manner. As KP levels in the ARC vary with photoperiodic and metabolic status, a photoperiod-driven influence of BEND neurons on neighboring KP neurons is plausible. The aim of this study was therefore to investigate a possible modulatory action of BEND on KP neurons located in the ovine ARC. Using confocal microscopy, numerous KP appositions on BEND neurons were found but there was no photoperiodic variation in the number of these interactions in ovariectomized, estradiol-replaced ewes. In contrast, BEND terminals on KP neurons were twice as numerous under short days (SD), in ewes having an activated gonadotropic axis, as compared to anestrus ewes under long days (LD). Injection of 5$\mu$g BEND into the third ventricle of SD ewes induced a significant and specific increase of activated KP neurons (16% versus 9% in controls) while the percentage of overall activated (c-Fos positive) neurons, was similar between both groups. These data suggest a photoperiod-dependent influence of BEND on KP neurons of the ARC, which may influence GnRH pulsatile secretion and inform KP neurons on the metabolic status.

Target-oriented data conditioning is a key part of any reservoir characterization workflow. Data conditioning is used to optimize the match between the synthetic data, used in the prestack inversion, and the real data. When this is done correctly, the accuracy and confidence of inversion results may be greatly improved. This is proved on prestack seismic inversion results from a resource play in Canada. The flow is broken down into prestack gather conditioning, which improves the signal-to-noise and gather flatness, and poststack conditioning, which further improves the coherency prior to applying spectral balancing. As a final key step, spatially variant amplitude balancing is used to calibrate the angle stacks to the expected background trend from the well synthetics. The combination of all steps is demonstrated via [Formula: see text] and mu-rho versus lambda-rho crossplots, between the inverted results and the well measurements, to provide a significant improvement on the resolution and accuracy of the final prestack inversion.

The originating base of large shield is a fundamental guarantee of shield machine prosperous assembly and originating posture. This paper based on Nanjing Weisan Road Tunnel Across Yangtze River, the requirements of large TBM assembly and the guarantee measures on originating posture is introduced.

Tuberculosis (TB) is a major cause of morbidity and mortality worldwide. This study evaluated the immune response in mice to members of the Mtb9.9 protein family. C57BL/6 mice were immunized with four different Mtb9.9 recombinant proteins to evaluate the humoral and cellular immune responses to each protein. Mouse splenocytes from these mice were stimulated in vitro for 72 h with the Mtb9.9 proteins. Concentrations of the cytokines interferon (IFN)-γ and tumor necrosis α (TNF-α) in the culture supernatants were increased compared with controls. Sera were taken from the same mice at 3 weeks after immunization and contained significantly higher levels of immunoglobulin (Ig)G2c antibody when compared with sera from control mice. Our findings indicate a bias toward T helper (Th)1-type cellular and humoral memory responses against Mtb9.9 recombinant proteins in mice. This study demonstrates that these proteins might be suitable candidates for use as subunit vaccines.

Background: Colostrinin™ (CLN), isolated from mothers’ pre-milk fluid (colostrum), is a uniform mixture of low-molecular-weight, proline-rich polypeptides. CLN induces neurite outgrowth of pheochromocytoma cells, extends the lifespan of diploid fibroblast cells, inhibits β-amyloid-induced apoptosis and improves cognitive functions when administered to Alzheimer’s disease patients. Objective: The aim of this study was to investigate potential allergic responses to CLN and its impact on allergic sensitization and inflammation caused by common allergens. Methods: We used a well-characterized mouse model of allergic airway inflammation. Changes in IgE/IgG1 and mucin levels, airway eosinophilia and hyperreactivity to methacholine were determined by ELISA, differential cell counting and whole-body plethysmography, respectively. Results: CLN did not increase IgE/IgG1 levels or induce cutaneous hypersensitivity reaction, airway inflammation and mucin production. Importantly, CLN significantly (p < 0.001) decreased IgE/IgG1 production, airway eosinophilia, mucin production and hypersensitivity induced by allergenic extracts from ragweed pollen grains and house dust mites. Conclusion: CLN itself is non-allergenic; however, it is effective in preventing allergic responses to known indoor and outdoor allergens. These data support the safe application of CLN and its potential use in the prevention of allergic inflammation in humans.

This case describes the difficulties and successes encountered in a reengineering effort. A team of consultants undertook reengineering the delivery of compensation and benefits at a large quasi-governmental agency. Benefits included six programs which accounted for several time-intensive processes such as “cafeteria plan” options for individual and family health coverage, a health benefits open enrollment period where information is dispersed to assist employees in plan selection; thrift spending account; and retirement accounts.

Forty-nine ambulatory residents participated in a study conducted to determine the relationship between premorbid life-style, work, and ways of handling stress, and wandering in dementia units. The sample consisted of 23 males and 26 females with a mean age of 79. Family members responded to open-ended questionnaires that asked about premorbid leisure activities, hobbies, exercise, stress management, type of employment and social interactions. Activities were ranked according to energy expended on the Metabolic Cost of Activities (MET) Scale. No activity equaled Inactive (0); 1.5-2 METS equaled Mildly Active (1), 2-3 METS equaled Moderately Active (2), and 3-4 METS equaled Very Active (3). Subjects were observed three times for one-hour intervals on each of three shifts (day, evening, night) at randomly selected times to assess wandering behavior. Behavior was logged every five minutes. The subjects' most frequent conditions were awake (21%), alone (20%), and in their own rooms (17%). Twenty-four (50%) of the subjects were observed pacing, and 16 (33%) were agitated/restless at some point in time. Statistical analyses showed no significant correlations between premorbid life-style variable rankings and the amount of time spent standing, walking and pacing. The findings suggest that wandering behavior is not influenced by premorbid life-styles.
