After pair-bonding, male prairie voles (Microtus ochrogaster) display aggression toward novel females but not toward their female partner. Here we show that this selective aggression in pair-bonded male prairie voles is associated with increased release of vasopressin (AVP) in the anterior hypothalamus (AH). Pharmacological activation of AVP-V1a receptors (V1aR) in the AH induced selective aggr...

Plasma platelet-activating factor acetylhydrolase (PAF-AH), also called lipoprotein-associated phospholipase A₂ (Lp-PLA₂), is a group VIIA PLA₂ enzyme that catalyzes the hydrolysis of PAF and certain oxidized phospholipids. Although the role of PAF-AH as a pro- or anti-atherosclerotic enzyme is highly debated, several studies have shown it to be an independent marker of cardiovascular diseases....

The reproductive strategy of two congeneric species (Astyanax janeiroensis--AJ and Astyanax hastatus--AH) was assessed, in order to address the costs imposed by different investment patterns, on four major life history characters: migratory behaviour, breeding time, fecundity and egg size. Altitudinal segregation of young and adult individuals plus data from the literature indicated that AJ is ...

Let X be a subset of an abelian group and a1, . . . , ah, a ′ 1 , . . . , a h a sequence of 2h elements of X such that a1 + · · ·+ah = a ′ 1 + · · ·+a h . The set X is a Sidon set of order h if, after renumbering, ai = a ′ i for i = 1, . . . , h. For k ≤ h, the set X is a generalized Sidon set of order (h, k), if, after renumbering, ai = a ′ i for i = 1, . . . , k. It is proved that if X is a g...

We determined the linezolid concentrations in serum samples and aqueous humors (AHs) from 21 patients undergoing cataract extraction. Cataract removal was performed at various times (from 60 to 270 min) after the end of a 30-min infusion of 600 mg of linezolid. Serum samples were obtained 1 h after the end of linezolid administration to determine the maximum concentration of linezolid (C(max));...

Alcoholic hepatitis (AH) is a type of acute-on-chronic liver failure and is the most severe form of alcoholic liver disease. AH occurs in patients with heavy alcohol abuse and underlying liver disease. In its severe form, AH carries a poor short-term prognosis. Although the existence of AH can be strongly suspected based on clinical and biochemical criteria, a definitive diagnosis requires a li...

Emerging evidence suggests that assisted hatching (AH) techniques may improve clinical pregnancy rates, particularly in poor prognosis patients; however, there still remains considerable uncertainty. We conducted a meta-analysis to verify the effect of AH on pregnancy outcomes. We searched for related studies published in PubMed, Web of Science, and Cochrane library databases from start dates t...

The effect of corticosteroids on aqueous humor (AH) formation rate and outflow facility was measured in the cat eye. AH formation rate was determined by continuous posteroanterior chamber perfusion with an AH-like buffer containing inulin-C*. It was found that the total quantity of inulin-C recovered through the anterior chamber outflow cannula could be used to estimate changes in outflow facil...

Aqueous humor (AH) supports avascular tissues in the anterior segment of the eye, maintains intraocular pressure, and potentially influences the pathogenesis of ocular diseases. Nevertheless, the AH proteome is still poorly defined despite several previous efforts, which were hindered by interfering high abundance proteins, inadequate animal models, and limited proteomic technologies. To facili...
