Mammalian thioredoxin reductases (TrxR) are selenoproteins with important roles in antioxidant defense and redox regulation, principally linked to functions of their main substrates thioredoxins (Trx). All major forms of TrxR are intracellular while levels in serum are typically very low.', 'Serum TrxR levels were determined with immunoblotting using antibodies against mouse TrxR1 and total enzyme activity measurements were performed, with serum and tissue samples from mouse models of liver injury, as triggered by either thioacetamide (TAA) or carbon tetrachloride (CCl4).', 'TrxR levels in serum increased upon treatment and correlated closely with those of alanine aminotransferase (ALT), an often used serum biomarker for liver damage. In contrast, Trx1, glutathione reductase, superoxide dismutase or selenium-containing glutathione peroxidase levels in serum displayed much lower increases than TrxR or ALT.

To test the hypothesis that hyporesponsiveness to ghrelin due to reduced growth hormone (GH) contributes to the aging-related hyperinflammatory state in sepsis.', 'Sepsis and septic shock are a serious problem, particularly in the geriatric population. Ghrelin is an endogenous ligand for the GH secretagogue receptor 1a (GHSR1a, ie, ghrelin receptor). The decline in GH with age is directly associated with many adverse changes that occur with aging. However, the role of GH, ghrelin, and GHSR1a in the age-associated vulnerability to sepsis remains unknown.', 'Male Fischer 344 rats (young: 3 months; aged: 24 months) were used. Plasma GH levels, ghrelin receptor expression, and neuronal activity in the parasympathostimulatory nuclei of the brain stem in normal young and aged animals were measured. Endotoxemia was induced by intravenous injection of lipopolysaccharide (LPS, 15 mg/kg BW).', 'While LPS-induced release of proinflammatory cytokines from macrophages isolated from aged rats decreased, LPS injection resulted in an in vivo hyperinflammatory state. GH levels were lower in aged rats, which was associated with lower expression of GHSR1a in the dorsal vagal complex and a decrease in parasympathostimulatory neuronal activity. GHSR1a antagonist elevated LPS-induced cytokine release in young rats. GH increased GHSR-1a expression in the dorsal vagal complex in aged rats. Coadministration of ghrelin and GH, but not ghrelin alone or GH alone, markedly reduced cytokine levels and organ injury after endotoxemia in aged rats, which was associated with significantly elevated parasympathostimulatory neuronal activity.

Previous studies on vaccination coverage in developing countries focus on individual- and community-level barriers to routine vaccination mostly in rural settings. This paper examines health system barriers to childhood immunisation in urban Kampala Uganda.', 'Mixed methods were employed with a survey among child caretakers, 9 focus group discussions (FGDs), and 9 key informant interviews (KIIs). Survey data underwent descriptive statistical analysis. Latent content analysis was used for qualitative data.', 'Of the 821 respondents in the survey, 96% (785/821) were mothers with a mean age of 26 years (95% CI 24-27). Poor geographical access to immunisation facilities was reported in this urban setting by FGDs, KIIs and survey respondents (24%, 95% CI 21-27). This coupled with reports of few health workers providing immunisation services led to long queues and long waiting times at facilities. Consumers reported waiting for 3-6 hours before receipt of services although this was more common at public facilities. Only 33% (95% CI 30-37) of survey respondents were willing to wait for three or more hours before receipt of services. Although private-for-profit facilities were engaged in immunisation service provision their participation was low as only 30% (95% CI 27-34) of the survey respondents utilised these facilities. The low participation could be due to lack of financial support for immunisation activities at these facilities. This in turn could explain the rampant informal charges for services in this setting. Charges ranged from US$ 0.2 to US$4 and these were more commonly reported at private (70%, 95% CI 65-76) than at public (58%, 95% CI 54-63) facilities. There were intermittent availability of vaccines and transport for immunisation services at both private and public facilities.
