Obstructive sleep apnea is increasing worldwide, leading to disordered sleep patterns and inflammatory responses in brain and peripheral tissues that predispose individuals to chronic disease. Pro-inflammatory cytokines activate the inflammatory response and are normally regulated by glucocorticoids secreted from adrenal glands. However, the temporal dynamics of inflammatory responses and hypothalamic-pituitary-adrenal (HPA) axis activation in relation to acute sleep fragmentation (ASF) are undescribed. Male C57BL/6J mice were exposed to ASF or control conditions (no ASF) over specified intervals (1, 2, 6, or 24 h) and cytokine gene expression (IL-1β, TNF-α) in brain and peripheral tissues as well as serum glucocorticoid and interleukin-6 (IL-6) concentration were assessed. The HPA axis was rapidly activated, leading to elevated serum corticosterone from 1–24 h of ASF compared with controls. This activation was followed by elevated serum IL-6 concentration from 6–24 h of ASF. The tissue to first exhibit increased pro-inflammatory gene expression from ASF was heart (1 h of ASF). In contrast, pro-inflammatory gene expression was suppressed in hypothalamus from 1 h of ASF, but elevated at 6 h. Because the HPA axis was activated throughout ASF, this suggests that brain, but not peripheral, pro-inflammatory responses were rapidly inhibited by glucocorticoid immunosuppression.

Abstract Study on freshwater ecology have been long focused on subtropical habitats with few references to tropical regions including Indonesia. Zooplankton, in particular, is an important component of aquatic ecosystem as they are key player of aquatic food webs, thus a solid understanding of their community structure can be of direct benefit to freshwater ecosystem management. The spatial patterns of zooplankton diversity in Lake Tondano, Celebes Island – Indonesia were studies in 2013, with the main aim was to understand how local environmental and habitat heterogeneity driving the zooplankton community structure. We performed field samplings to collect zooplankton using a vertical tow with a 156 μm mesh plankton net from 1 meter above sediment to the surface and to measure environmental parameters using portable multi probes water quality checker from three different water columns. The sampling sites were selected to include different habitats within the lake to look at diversity of the entire zooplankton communities including Rotifers, Cladocerans, and Copepods in Lake Tondano, Indonesia. A total of 21 species of cladocerans, 31 copepods, and 60 rotifers were identified from Lake Tondano. Our result indicates a relatively low number of cladocerans which is may be associated with high predatory pressure from planktivorous fish, especially within the open pelagic zone.

Pharmaceutical excipients, such as surfactants, amino acids, and polymers, have often been used to improve the physicochemical properties of protein drugs. However, the effects of these additives are limited because of factors such as their weak interactions with protein drugs. In the present study, we evaluated the application of a supramolecular polymer, aminated polyrotaxane (NH2-PRX), which can strongly interact with protein drugs via its dynamic and transformable properties, as a new pharmaceutical excipient for these agents. As a conventional control polymer with low mobility and average complexation ability, aminated dextran (NH2-DEX) was also prepared. NH2-PRX significantly reduced the aggregation of antibodies induced by shaking, compared with NH2-DEX. The adsorption of insulin onto glass and polypropylene containers was also reduced by the addition of NH2-PRX. In addition, the in vivo bioactivity of insulin was completely retained in the presence of NH2-PRX. Moreover, severe adverse effects were not observed following the administration of NH2-PRX. These findings indicate the potential use of NH2-PRX as a transformable pharmaceutical excipient for protein drugs.

It has been submitted that, for the very large number of different traditional type formulae to determine price indices associated with a pair of periods, which are joined with the longstanding question of which one to choose, they should all be abandoned. For the method proposed instead, price levels associated with periods are first all computed together, subject to a consistency of the data, and then price indices that are true taken together are determined from their ratios. An approximation method can apply in the case of inconsistency. Here are illustrations of the method.

This paper focuses on negative indefinites in Portuguese, paying particular attention to nemigalha, a negative indefinite that disappeared from the language around the 16th century. We claim that nemigalha originates from the reanalysis of the negative particle nem and the minimizer migalha in an early stage of the language, starting as a weak negative polarity item and then becoming a strong negative polarity item, in the sense of Martins (1997, 2000). It is well known that minimizers can grammaticalize into intrinsically negative items, being good candidates to undergo the Jespersen Cycle (Jespersen 1917). Although that was not the case of nemigalha, it completed all the grammaticalization stages proposed by Garzonio & Poletto (2008, 2009), losing all the properties of a common noun and being able to stand alone as the only negative marker in preverbal position. The comparison between nemigalha and the negative indefinite nada shows that both items exhibited similar behaviour and occurred in identical contexts, probably acting as competing items until nemigalha’s disappearance. Furthermore, a few examples from the 16th century suggest that nemigalha might have become a more functional item, participating as a negation marker in presuppositional contexts (cf. Larrivée 2010 and Hansen 2013).

Pharmaceutical excipients, such as surfactants, amino acids, and polymers, have often been used to improve the physicochemical properties of protein drugs. However, the effects of these additives are limited because of factors such as their weak interactions with protein drugs. In the present study, we evaluated the application of a supramolecular polymer, aminated polyrotaxane (NH2-PRX), which can strongly interact with protein drugs via its dynamic and transformable properties, as a new pharmaceutical excipient for these agents. As a conventional control polymer with low mobility and average complexation ability, aminated dextran (NH2-DEX) was also prepared. NH2-PRX significantly reduced the aggregation of antibodies induced by shaking, compared with NH2-DEX. The adsorption of insulin onto glass and polypropylene containers was also reduced by the addition of NH2-PRX. In addition, the in vivo bioactivity of insulin was completely retained in the presence of NH2-PRX. Moreover, severe adverse effects were not observed following the administration of NH2-PRX. These findings indicate the potential use of NH2-PRX as a transformable pharmaceutical excipient for protein drugs.
