TL;DR: Investigation of rumen volatile fatty acids, lactate concentrations and pH over periods which included regular feeding and 48 h starvation resulted in a marked decrease in salmonella numbers, while lower VFA concentrations had little or no inhibitory effect on growth.

TL;DR: In this article, a randomized, half-facial treatment study was conducted to determine which of two different incubation times (30 minutes and 3 hours) is more effective in PDT with intense pulsed light (IPL) for acne vulgaris.
Abstract: BACKGROUND Photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) is used for effective treatment of facial acne vulgaris.
OBJECTIVES To determine which of two different incubation times (30 minutes and 3 hours) is more effective in PDT with intense pulsed light (IPL) for acne vulgaris.
METHODS & MATERIALS Twenty Korean subjects with moderate to severe acne were enrolled for a randomized, half-facial treatment study. Three sessions with short incubation with ALA plus IPL (30 minutes, n=9) or long incubation with ALA plus IPL (3 hours, n=11) on one side of the face and IPL alone on the other side were performed at 1-month intervals.
RESULTS All subjects showed improvement in inflammatory acne lesions after three sessions of ALA-PDT or IPL alone (p<.001 in all groups). The degree of improvement in inflammatory acne lesions was greater in the long incubation time group than the short incubation time group or the IPL-alone group, although the mean reduction of inflammatory acne lesions was statistically different only between the long incubation group and the IPL-only group (p=.01). There were no statistical differences between the short incubation group and IPL-alone group. All three groups had decreased sebum secretion after three sessions (p<.001 in all groups), but the differences between groups were not statistically significant. Only transient erythema and mild edema were reported for all treatment groups.
CONCLUSION PDT with a long ALA incubation time might be more adequate for a pronounced outcome with inflammatory acne.

TL;DR: Embryonic growth was modestly accelerated, reflected in higher embryonic weights at day 6 and 10 and a significant earlier hatching; hatchling weights were not different between treatment groups, and the capacity of albumen to cope with higher environmental CO2 was illustrated.

TL;DR: MG-derived AGEs may have an important role as the precursors of protein aggregation, which, in turn, may be associated with physiological complications.

TL;DR: Dummy eggs were added to naturally incubated clutches of Greater Snow Geese in order to evaluate egg temperature during laying and incubation, and factors influencing egg cooling rate during female recesses, and as laying progressed, both nest attentiveness by females and egg temperature progressively increased.
Abstract: Dummy eggs were added to naturally incubated clutches of Greater Snow Geese (Chen caerulescens atlantica), an arctic-nesting species, in order to evaluate egg temperature during laying and incubation, and factors influencing egg cooling rate during female recesses. As laying progressed, both nest attentiveness by females and egg temperature progressively increased. Although the time spent at nest after laying the penultimate egg was relatively high (69% vs. 91% during incubation), mean egg temperature was still 5.7°C lower than during the early incubation period. This suggests that little embryonic development began before clutch completion. Thereafter, egg temperature averaged 37.1 ± 0.1°C during periods where females were present, a value that decreased only slightly when incubation recesses are included (36.8°C). This is a high temperature in comparison to other arctic-nesting geese. A modest increase (1.7°C) in mean egg temperature was observed as incubation progressed, but egg temperature wa...
