Abstract Rabbit skeletal muscle phosphorylase kinase has been obtained as a nearly homogeneous protein showing single peak on electrophoresis and in the ultracentrifuge. Incubation of purified with γ32P-ATP presence Mg++ ions activates enzyme; this process is accompanied by phosphorylation protein. Activation occur more rapidly when cyclic 3',5'-AMP or glycogen present activation reaction mixtures, but these two substances apparently act different mechanisms since their effects are additive....
Artificial light at night (ALAN) is increasing exponentially worldwide, accelerated by the transition to new efficient lighting technologies. However, ALAN and resulting pollution can cause unintended physiological consequences. In vertebrates, production of melatonin—the “hormone darkness” a key player in circadian regulation—can be suppressed ALAN. this paper, we provide an overview research on melatonin vertebrates. We discuss how disrupts natural photic environments, its effect rhythms,...

Abstract When purified rabbit skeletal muscle phosphorylase kinase is activated by preliminary incubation with γ-32P-ATP in the presence of Mg++ ions, it incorporates covalently bound 32P. All 32P as alkali-labile phosphate, presumably on seryl residues. Serine phosphate has been isolated after partial acid hydrolysis labeled enzyme. Skeletal and other tissues contain a phosphatase that catalyzes dephosphorylation kinase, shown this reaction accompanied reversal activation. The phosphatase,...

Abstract Recent declines in Atlantic salmon Salmo salar populations are generally attributed to factors their marine life-phase. However, it is postulated that affecting freshwater life-phase might impact survival, such as the influence of body size. While larger smolts widely hypothesized have higher survival rates, empirical support remains scant, part due inadequate data and ambiguous statistical analyses. Here, we test smolt size on return a proxy for using 12-year dataset 3688 tagged...
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their migratory behavior remains poorly understood. This study used 9 years of trout ( Salmo trutta ) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected migrating downstream spring, 99 adults returning first migration the River Frome (Dorset, UK) investigate on timing maiden sojourn duration. Age‐specific...
Summary 1. The effects of an experimentally imposed low summer flow on habitat use, displacement and survival wild populations juvenile salmon ( Salmo salar ), trout trutta ) grayling Thymallus thymallus were investigated in a chalk stream. use mobility the fish response to reduced was determined using passive integrated transponder‐tag detector systems. 2. Habitat compared that available under different regimes. These consisted initial control phase normal flow, abrupt step change 21 days...
Summary The effect of a range ecologically relevant broader spectrum street light intensities on the dispersal timing Atlantic salmon ( Salmo salar ) fry was investigated to assess efficacy proposed management tool, dimming lamp brightness, for reducing ecological consequences artificial night aquatic ecosystems.

Introduction Postoperative acute kidney injury (AKI) is a common complication in cardiac surgery. Levels of intravascular haemolysis are strongly associated with postoperative AKI and prolonged (>90 min) use cardiopulmonary bypass (CPB). Ferrous plasma haemoglobin released into the circulation acts as scavenger nitric oxide (NO) produced by endothelial cells. Consequently, vascular bioavailability NO reduced, leading to vasoconstriction impaired renal function. In patients cardiovascular...
Abstract A portable multi‐point decoder system deployed in a tributary of the River Itchen, southern English chalk stream, recorded habitats used by PIT‐tagged juvenile salmon, Salmo salar L., trout, trutta L. and grayling, Thymallus thymallus with high degree spatial temporal resolution. The fishes’ use habitat was monitored at 350 locations throughout stream during September/October 2001 (feeding period) January/February 2002 (over‐wintering period). Salmon parr tended to occupy water...
SUMMARY The forces during cryosectioning were measured using miniature strain gauges attached to a load cell fitted the drive arm of Porter‐Blum MT‐2 cryomicrotome. Work was calculated and data normalized standard (1 mm × 1 0·5 μm) section. Thermal energy generated also calculated. Five parameters studied: cutting angle, thickness, temperature, hardness, block shape. Force patterns could be divided into three major groups thought represent (Type I), large fracture planes > 10 μm in length...
Abstract – The movements of wild European eels ( Anguilla anguilla L.) were monitored continuously over a 2‐year period in tributary the River Itchen, Hampshire, UK, using passive integrated transponder (PIT) antenna system. time these was then related to number and calculated environmental parameters. No eel recorded winter months when mean stream temperature below 10 °C. numbers peaked May, water temperatures day length increasing. movement significantly P < 0.001, R 2 = 0.45, N 72)...
The downstream movements of wild Atlantic salmon, Salmo salar L., from their established feeding territories in the River Itchen, Hampshire, UK, were logged continuously over an 11‐month period using a passive integrated transponder (PIT) antenna system. time these was then related to number monitored and calculated environmental parameters. Initial movement smolts April correlated with onset darkness, at which salmon moved alone. No relationship found between migrating river flow or maximum...
Abstract The effects of changes in shading (through riparian canopy removal and re‐growth) on juvenile salmon, Salmo salar L., trout, trutta grayling, Thymallus thymallus (L.) populations, macroinvertebrate biomass species composition a chalk stream southern England were examined. Low levels in‐stream weed growth, because by closed tree canopy, diminished production diversity. 0+ salmon trout had lower densities under relative to adjacent open sites with substantial cover, where fish also...
