The resulting model is computationally efficient enough to be applied at large spatial scales and yet yields spatially explicit results that are useful for conservation planners tasked with targeting sub-field scale management practices. In addition to predicting when and where storm runoff will occur, this model uses open source coding (R-programming language, R Core Team, 2013) and information (e.g., USGS and USDA geographical information) in a manner that is easily applicable

to web-based applications. The modeling approach adopted here is similar to that used by the early forms of TOPMODEL (Beven and Kirkby, 1979), STOPMODEL (Walter et al., 2002), and VSLF (Schneiderman et al., 2007) in which GSK126 ic50 the soil- and ground-water budgets are maintained at the watershed scale (Fig. 1) while storm runoff is distributed according to topographic position within the watershed. The soil water budget that forms the backbone of the model was first proposed by Thornthwaite and Mather (1955). Daily modeled soil water and evapotranspiration (ET) are based on soil water status and potential evapotranspiration (PET): equation(1a) SWd=SWd−1expId−CcPETdAWC for   Id−CcPETd<0 equation(1b) SWd=SWd−1+(Id−CcPETd)−D for   Id−CcPETd≥0SWd=SWd−1+(Id−CcPETd)−D for   Id−CcPETd≥0

equation(1c) D=SWd−1+(Id−CcPETd)−AWC for   SWd−1+(Id−CcPETd)>AWCD=SWd−1+(Id−CcPETd)−AWC for   SWd−1+(Id−CcPETd)>AWCwhere SWd is Selleckchem Anti-diabetic Compound Library soil water depth on day d (mm), AWC is the watershed-wide average available water capacity of the soil (mm), Id is water input on day d (rain + snow melt − Qd) (mm), Cc is a generalized crop coefficient to scale PET under various effective vegetative covers (adopted from Shuttleworth, 1992), D is drainage to the groundwater (mm), and Qd is storm runoff on day d (mm). Storm runoff is estimated using Eq. (2) (discussed in the next paragraph). The watershed-average

HSP90 AWC is calculated from the area-averaged AWC-percentage (mm water per mm of soil depth) and soil depths from the NRCS SSURGO database ( NRCS, 2013). Daily PET is calculated using the Priestley–Taylor (1972) equation using daily maximum and minimum air temperature to estimate net radiation ( Archibald and Walter, 2013). A similar method is used to model daily snow ( Walter et al., 2005 and Fuka et al., 2012). Baseflow is modeled using a linear reservoir model adopting an average regional coefficient of 0.1 day−1 based on recession flow analysis of streams in the northeastern US ( Frankenberger et al., 1999). Storm runoff is estimated using the SCS Curve Number equation (e.g., USDA-NRCS, 2004): equation(2) Qd=Pd2Pd+Sdwhere Qd is runoff on day d (mm), Pd is the effective precipitation and/or snow melt (mm) for that day defined as rain plus snowmelt minus an initial abstraction – here we use initial abstraction = 0.

For this purpose body temperature and weight were measured immediately before treatment and body temperature was measured again 4 h post-injection. An additional measurement of body weight was taken 21 h post-injection

after the animals had been subjected to the open field (OF) test (n = 8). In a separate experiment (experiment 2.2), mice were euthanized 3 h after injection of PRR agonists ( Fig. 1) and the brains were collected for immunohistochemical visualization of c-Fos expression in select brain regions (n = 3–5). Following euthanasia the brains were removed, put on dry ice and stored at −70 °C ABT-737 chemical structure until use. Protocol 3 was used in 3 separate experiments (Fig. 1) in which the effects of MDP and FK565 in combination with the lower dose of LPS (0.1 mg/kg) were investigated. In experiment 3.1 body temperature and weight were measured before treatment and the body temperature was measured again 4 h post-injection. The OF test was conducted 21 h after the treatment

and body weight was measured after the OF test (Fig. 1). Subsequently the animals were subjected to the tail suspension test (TST) for 6 min (25.5 h post-injection) and euthanized 30 min after start of the TST. Blood was sampled to measure the plasma levels of cytokines, corticosterone, kynurenine and tryptophan (Fig. 1). In addition, the brains were collected, frozen in −70 °C cold 2-methyl butane (Fisher Scientific, Leicestershire, UK) and stored at this temperature until measurement of cytokines (n = 7–8). In experiment 3.2 mice (Fig. 1) were euthanized PTC124 clinical trial 3 h after injection of PRR agonists to record the levels of circulating and brain cytokines and circulating corticosterone without interference by any behavioral test (n = 7–8). In a further experiment (experiment 3.3) singly housed mice were subjected to the forced swim test (FST) 21 h post-injection, since depression-like behavior has been shown to be modified by different housing conditions (Painsipp et al., 2011) (n = 7–8). All compounds were dissolved in pyrogen-free sterile saline (0.9% NaCl) and pyrogen-free

sterile saline injected intraperitoneally (i.p.) at the same volume (50 μL/10 g body weight) was used as vehicle (VEH) control. For the analysis of the interaction between NOD agonists and LPS, two doses of LPS were examined. First, the widely used Avelestat (AZD9668) dose of 0.83 mg/kg LPS inducing the full spectrum of sickness (Frenois et al., 2007 and Painsipp et al., 2011) was used. Since, in combination with the NOD agonists, this dose of LPS led to a marked decrease in body temperature and locomotion, while a ceiling effect was observed with other parameters, a lower dose of 0.1 mg/kg LPS was also tested. The doses of the NOD agonists (see below) were chosen on the basis of their immunological effects in vivo ( Parant et al., 1995 and Shikama et al., 2011) and the results of pilot experiments. Thus, doses of 1 mg/kg (LabMaster studies) and 3 mg/kg (ex LabMaster studies) of MDP and 0.001 mg/kg (LabMaster studies) and 0.

Thus the most significant gains in Tm due to protein deuteration are only observed at temperatures around 50 K and below. Unlike the 1/Tm temperature dependence, the spin longitudinal relaxation rate (1/T1) does not show any major difference between the non-deuterated and all-deuterated samples, which indicates that within this temperature range, the nuclear spins

do not play a significant role in the spin–lattice relaxation mechanism. For both samples 1/T1 shows slight temperature dependence, and during the observed temperature range BYL719 it does not approach the value of 1/Tm suggesting that T1 processes do not have a significant effect on the electron spin echo dephasing [3]. We have shown the strong effect of protein deuteration on Tm. However as Tm is extended it becomes more sensitive to other effects like instantaneous diffusion and electron spin–spin diffusion [17]. The electron spin echo dephasing observations, in which the histone octamer was increasingly segmentally deuterated, showed, in addition to strong ESEEM modulations, an oscillation resulting from the electron dipole–dipole interaction between the two spin labels present on the protein (see Fig. 2). Such distance dependent dipolar PARP assay interactions were only observed in the case of H3-D/H4-D and All-D samples due to their long Tm. In Fig. 2 we can see that the longer the Tm, the more pronounced the electron dipole–dipole interaction.

The observation that the 2 pulse ESE experiment is capable of detecting electron spin–spin interactions in biradicals has been made previously [16]. In a two-pulse echo experiment, when the second pulse is applied and flips two dipole-coupled spins simultaneously, the dipole interaction does not refocus and leads ID-8 to a dephasing of spin pairs, this effect is known as instantaneous diffusion. Two cases

can be envisaged. One situation is where the spin pairs are randomly distributed and so there will be a wide distribution of dipolar interactions, D, and therefore the echo oscillations, occurring at a range of frequencies, average out, leaving only an exponential-like echo decay contribution. In the second case, when the spin pairs have a defined dipole interaction, D, the echo decay will be modulated by the dipole–dipole frequency, y(τ) ∼ cos(Dτ) [16]. The H3-D/H4-D and All-D histone octamer constructs clearly fulfil the requirements for a dipolar interaction to be observed in a 2 pulses ESE experiment since they are double spin labeled, with a defined dipole–dipole interaction, and have long Tm. The Fourier transform of the ESE decay yielded a dipolar coupling which is in good agreement with the PELDOR data (see supplementary material Fig. S4a and b). In order to get more insight into the effect of deuteration, we have also studied the concentration dependence of Tm ( Fig. 5) for the fully deuterated sample at 50 K.

PAHs are often produced by incomplete fossil fuel burning and accidental discharges of petroleum products from factories,

vehicles, and ships (Fang et al., 2003, Doong and Lin, 2004, Ko and Baker, 2004 and Froehner et al., 2010). They have been declared as primary pollutants by the Environmental Protection Agency, United States, due to their carcinogenicity, toxicity, and mutagenicity. Recent research has shown that PAHs can be transported from terrestrial sources to estuaries and nearby coastal areas Cyclopamine research buy via discharges and land runoff (Gogou et al., 1996, Bouloubassi et al., 2001, Li et al., 2006, Hung et al., 2010, Hung et al., 2011, Cheng et al., 2010 and Ko et al., 2014a). After PAHs have been transported to estuarine and coastal environments through various physical processes, they will be incorporated with phytoplankton or detritus. Subsequently,

they may enter marine food chains to be highly accumulated in marine organisms of higher trophic RO4929097 molecular weight levels (e.g., zooplankton, fish larvae, fishes, or mammals) via absorption and/or bioaccumulation (Landrum et al., 1992, Burkhard, 1998, Cailleaud et al., 2007, Vigano et al., 2007, Froehner et al., 2010, Hung et al., 2011 and Ko et al., 2014b). Therefore, an understanding of how PAHs are distributed and accumulated in zooplankton contributes to a better understanding of PAHs pollution in marine ecosystems. The East China Sea (ECS) is a large marginal sea of the Pacific Ocean and is characterized by high values of primary production, particulate organic carbon flux,

carbohydrate Adenosine yield, and carbon sequestration rate (Gong et al., 2003, Gong et al., 2006, Gong et al., 2011, Hung et al., 2009a, Hung et al., 2010, Hung et al., 2013, Chen et al., 2013a, Chou et al., 2009, Chou et al., 2011 and Chou et al., 2013). The ECS also supports many key fisheries stocks, e.g., croakers, mackerels, hairtails, and pomfrets (Chen et al., 1997; Hung and Gong, 2011). According to previous studies, distinct salinity fronts have been frequently found in the ECS and may be important for small fish and plankton (Belkin et al., 2009 and Chen, 2009). Besides numerous nutrient input to the ECS, previous research has reported that the Changjiang River (Yangtze River) transports thousands of tons of pollutants, such as heavy metals and persistent organic pollutants, including hydrocarbons (Lü and Zhai, 2005), pesticides, and PAHs (Guo et al., 2006, Feng et al., 2007, Müller et al., 2008 and Deng et al., 2013) to the ECS per year. These PAHs discharged to the ECS may be easily accumulated in marine animals inhabiting the ECS through feeding links.

Our www.selleckchem.com/products/Vorinostat-saha.html four-year study indicated that inter tillage and subsoiling loosen the soil, break up the plow pan caused by multiyear conventional soil management, and enhance root penetration to depth. Subsoil tillage management also reduces soil bulk density [22] and [28], deepens the active soil layer, and effectively increases soil water storage capacity [15] and [31]. After

subsoiling tillage, the proportions of root length and surface area in deeper soil were significantly increased, especially under subsoil tillage to 50 cm (Fig. 2 and Fig. 3), owing largely to the increased depth of the subsoil, which promotes root proliferation during the growing season. Two main contributions are root length and root diameter, which result in increased root surface for water and nutrient absorption

[32]. Dai et al. [33] emphasized that the root distribution under the plow pan may also play a key role in the uptake and utilization of nutrients and water in deep soil, especially after flowering, for the reason that the active layer for nutrient uptake by the root system is then below the 30 cm soil layer [34]. At the early filling stage, the uptake capacities for nutrients and water in the soil under the subsoil tillage treatments were greater than that under the CK treatment (Table 3, Fig. 6). Subsoil tillage also had positive effect on soil moisture, especially in deep soil, and soil water content was significantly increased below 40 cm, even during a dry INK 128 in vitro season (Fig. S1). Thus, subsoil tillage not only

enhances soil water storage capacity but enhances crop uptake of nutrients and water, increasing grain weight [21] and ultimately, grain yield of maize [35] and [36]. The depth of subsoiling is an important cost consideration for farmers. Most of the published papers RVX-208 concerning northeastern China were reviewed and the results suggested no significant difference between 30 and 40 cm subsoiling depths (Table 5). Most studies have been performed over a single year with too-small differences in subsoiling depth to reflect the actual situation. In the present study, no significant differences were observed in N, P, and K accumulations, biomass, yield and components in maize under different subsoil tillage treatments except in 2012. Environment (year) and interaction with subsoiling treatment showed a significant effect on nutrient uptake, plant growth, and grain yield (Table 1). An accurate evaluation of subsoil tillage should be obtained by a long term experiment [15]. However, the deeper the subsoiling layer, the more roots developed in deeper soil under the T2 treatment, and root diameter under the T2 treatment was significantly higher than that under the T1 treatment. Our analysis suggests that subsoil tillage as deep as the 50 cm soil layer improves soil physical behavior and reduces soil mechanical resistance to root penetration [22].

A subgroup of 27 patients with MCA occlusion treated with intravenous thrombolysis was included in the analysis of recanalization

characteristics. Patients were excluded due to lack of evidence of ICA or MCA occlusion on CTA [17], absence of temporal windows [11], incomplete or poor quality CTA [4], PCA occlusion [1] or aplastic or hypoplastic ACA [3], and non-stroke [1]. Occlusion site was determined by CTA and included 42 M1/M2 occlusions and 11 intracranial ICA occlusions. Baseline characteristics of the main sample and MCA thrombolysis subgroup are shown in Table 1 and Table 2. Significant FD to the ACA was present in Selleck SP600125 24/53 (45%) patients and to the PCA in 8/38 (21%) patients. Because adequate insonation of both PCAs was not possible in 15/53 (28%) of patients, further analysis of PCA FD was not undertaken. The differences in admission and outcome variables between groups

defined by the presence or absence of FD are displayed in Table 3. The presence of ACA FD was strongly associated with a CTA good collateral flow grade; 18 of 23 (78%) with good CTA collaterals had an ACA ratio greater than 1.3. However, 23 of 26 (88%) VX-809 ic50 with reduced CTA collaterals had an ACA FD ratio less than 1.3 (Odds ratio 27.6, p < 0.001). Twenty-four hour core infarct expansion (Δ core >5 ml between baseline and 24 h imaging) was also strongly associated with ACA FD where only 6 of 22 patients (27%) with an ACA FD ratio of greater than 1.3 had infarct core growth compared with 22 of 28 (78%) with ACA FD ratios of less than Bcl-w 1.3 (Odds ratio 9.7, p < 0.001). The presence of ACA FD may indicate a subgroup of patients with better collateral flow and a relatively stable ischemic penumbra. After adjusting for occlusion site, stroke onset time to CT, age and gender, the two predictors of baseline infarct core volume on linear regression analysis were FD (p < 0.001) and acute NIHSS (p = 0.002). Predictors of penumbral volume, after adjusting for occlusion site, acute NIHSS, onset time to CT and gender, FD (p < 0.001) and younger age (p = 0.016) (r2 = 0.3707) remained

significant. Predictors of 24 h infarct volume after adjusting for occlusion site, therapy with thrombolytic agent, and stroke onset to thrombolytic treatment time were: FD (p < 0.001), major reperfusion (p < 0.001) and lower acute NIHSS (p = 0.02) (r2 = 0.6689). Independent predictors of a favourable clinical outcome, as measured by 90 day mRS 0–2, were FD (OR 27.5, p < 0.001), major reperfusion (OR 21.1, p = 0.005; Table 4). All patients with ICAO as the site of vessel occlusion had a poor outcome. The characteristics of the patients with MCA occlusion treated with intravenous thrombolysis are shown in Table 2. Patients with major reperfusion post-thrombolysis were significantly older than those with non-reperfusion (71 years vs 56 years, p = 0.

The strong sequence identity suggests that moojenin belongs to the PIIIb subclass of SVMPs, which undergo autolysis/proteolysis in the spacer region to release a fragment consisting of disintegrin-like

“Snake venoms of the genus Lachesis comprise a complex mixture of pharmacologically active substances, such as metalloproteases ( Rucavado et al., 1999), phospholipases A2 ( Ferreira et al., 2009), serine proteases ( Magalhães et al., 1997) and other important enzymes. The venom of Lachesis muta, from Brazil ( Campbell & Lamar, 1989), contains l-amino acid oxidase (LAAO; EC 1.4.3.2), but its functional and structural characterization has not been performed ( Sanchez and Magalhães, 1991). This venom induces tissue damage, nausea, vomiting, sweating, bradycardia, hypotension, shock, and, in severe cases, death due to neurotoxic, hemorrhagic and coagulant activities of this complex mixture of pharmacologically active substances ( Jorge this website et al., 1997). LAAOs are homodimeric

flavoenzymes that catalyze the stereospecific oxidative deamination of l-amino acids by reduction of cofactor FAD. This reaction generates an intermediate

imino acid which produces ammonia and the corresponding α-keto acid. Selleckchem Palbociclib In a parallel reaction, the reoxidation of cofactor FAD by molecular oxygen generates hydrogen peroxide (Massey and Curti, 1967; Curti et al., 1992; Sun et al., 2010). According to Du and Clemetson (2002), snake venom LAAOs (svLAAO) have 110–150 kDa when determined by gel filtration, or 50–70 kDa as judged by electrophoresis on polyacrylamide gel with sodium dodecyl sulfate (SDS-PAGE). To exert their activity, LAAOs may be organized as dimers, therefore with molar mass between 110 and 150 kDa. Pawelek et al. (2000) showed that Calloselasma rhodostoma LAAO is a homodimer of 55 kDa monomers. Furthermore, svLAAOs may be acidic or basic proteins, showing isoelectric points ranging from 4.4 to 8.5 ( Ahn et al., 1997; Curti et al., 1992; Du and Clemetson, 2002). Some svLAAO crystal structures have been determined ( Moustafa et al., 2006; Zhang et al., 2004) revealing a functional dimer in which each monomer consists of a FAD-binding domain, a substrate-binding domain and a helical domain that is involved in protein dimerization. Concerning enzymatic properties, different svLAAOs have shown a preference for hydrophobic l-amino acids. This catalytic profile has been observed with LAAOs from Naja naja oxiana ( Samel et al., 2008), Bothrops pirajai ( Izidoro et al., 2006) and C. rhodostoma ( Ande et al., 2008).

Patients’ selection of their preferred decision-making style is only the first step in EOL decision-making. Implementing decisions is the crucial next step. Implementation strategies should be distinguished by whether participants (1) made and clearly communicated their decisions to those who needed to know them, (2) made but did not clearly communicate their decisions to others, or (3) did not make decisions or even minimally prepare others to make decisions for them and were thus at risk http://www.selleckchem.com/products/cobimetinib-gdc-0973-rg7420.html for receiving any treatment by default [31]. Autonomists followed through either by completing a living will that included directions about

life-sustaining treatments or by naming someone as their medical power of attorney and discussing their wishes with that person, or both. There was a somewhat fluid transition to the Authorizers, as some would not specifically name someone as their power of selleck products attorney. If they felt that the potential for conflict

was low due to only one or two potential legal decision makers, they were inclined to only verbally discuss their wishes and not formally appoint a power of attorney. Absolute Trusters commonly expressed complete trust in the person who would be their legal surrogate. They either felt the person would make “right” decisions because they knew the person well and trusted her/him; or because the person knew the patient well and thus would know to do the “right” thing. Their follow-through consisted only of identifying a power of attorney in cases where the legal surrogate might not be their preferred one. Despite consisting of only two patients, the Avoiders were a heterogenous group. One (Hispanic) Avoider let others decide quasi-by-default, because he had not thought Mirabegron about things and was not sure about what he wanted. It was not because he put complete trust in someone to make the “right” decisions. He had not been challenged

to think about EOL care or he had avoided discussing it, thus his wife had to decide for him without any guidance. The other (African American) Avoider similarly let others decide by default, but he did not appreciate this as letting others decide. Because he put complete faith in God to make all decisions, any decision-making on his part – or any other persons’ part – was superfluous. This patient considered deciding anything as unnecessary as all decisions lie in God’s hands. Limitations of this qualitative study relate to the number and composition of the focus groups, an academic setting, and the mostly male population of a VA Medical Center. Strengths of our study are that we directly obtained information from patients who were living with serious life-threatening illnesses, who were well familiar with EOL decision-making, and that we purposively included patients with diverse racial/ethnic background.

Patients who fail to respond to these measures may have the dose of the EGFR inhibitor interrupted or dose

reduced. Gastrointestinal side effects including diarrhea (54%), nausea (33%), vomiting (23%), stomatitis (17%), and abdominal pain (11%) have been reported. EGFR is frequently overexpressed in gastrointestinal normal mucosa. There is evidence that EGFR is a negative regulator of chloride secretion. EGFR inhibitors could, therefore, increase chloride secretion by blocking this regulation loop and thereby inducing secretory diarrhea. Diarrhea induced by inhibitors that target the EGFR pathway can be managed easily by reducing the dose of the oral compound, which rapidly lowers the incidence and severity of diarrhea. Rarely does treatment have to be interrupted. Loperamide is a useful treatment that can decrease intestinal motility signaling pathway [49]. Like ocular complication such as conjunctivitis, hepatic as increase in Liver Function Tests, renal, hematologic

side effects including leukopenia (25%) and anemia (16%) have been reported in patients receiving cetuximab. Remarkable developments in the systemic treatment of advanced non-small-cell lung cancer have taken place over the past few years. Targeted therapies have been largely employed in patients with far advanced disease, and some of them have demonstrated consistent activity in this setting. Epidermal growth factor receptor inhibitors cause dramatic response in patients especially

with EGFR mutation. As oncology trends towards personalized therapy to reach the optimal efficacy of drug with BAY 73-4506 cost less side effect, anti EGFR and or third line TKIs have proven to be promising effective drugs in Sitaxentan lung cancer treatment as first, second and maintenance therapy which encouraging further trials in this field. Combined irreversible inhibition of EGFR revealed striking benefit compared to chemotherapy alone. The development of resistance, tumor heterogeneity, and the need to rebiopsy the tumor are all challenges that requires further study to optimize the management of patients with NSCLC.

“We have recently witnessed a remarkable progress in our understanding of molecular biology and signalling pathways of NSCLC cells which resulted in ErbB targeted therapies, ALK inhibitors and other targeted agents being now in clinical trials. However, a substantial number of NSCLC patients remain non-responsive or relapse early on these targeted therapies. Improved understanding of the functioning of ErbB receptor family have led to second generation active anti-ErbB therapies. It is clear from different preclinical and clinical studies that combined anti-ErbB therapies have a superior efficacy to single agent therapies. In future it will be essential to characterize mutations of resistance in each line of treatment.

Systems combining phosphorothioate and bridging oxygen-substitutions (Table 3, entry 7) have demonstrated potential as therapeutics against Alzheimer’s disease owing to their metal click here ion chelation properties [47 and 48]. The use of sulfur-based analogues in the determination of mechanism has been reviewed recently [49]. Recent synthetic advances have also given (easier) access

to: azido-phosphonate dNTPs, where bridging O-atoms have been replaced by CHN3 groups (Table 3, entry 8), and these analogues can be isolated as separate diastereomers [50]; and oxymethyl analogues (CH2 insertion between O and P within anhydride linkages) for following ApnA and NpnN degradation and metabolism (Table 3, entry 9) [51]. Phosphonate NDP-sugar analogues, where the C1-oxygen of the glycosyl group has been replaced by methylene, have given insight into the mechanism of UDP-apiose/UDP-xylose synthase (Table 3,entry 10) [52], and bis-α,β-β,γ-CF2-NTPs offer sterically undemanding mimics that do not hydrolyse while maintaining comparable polarity properties to their natural NTP progenitors (Table 3,entry 11) [53]. Multi-faceted approaches

combining several experimental techniques and/or computational methods are currently giving some of the clearest pictures of phosphoryl transfer strategies. Most of these approaches have, in principle, been available for some time, however, experimental difficulties have precluded their exploitation. Synthesis selleck chemicals llc of analogues remains a substantial obstacle, with many ‘obvious’ analogues only becoming

accessible through painstaking development of challenging routes. This is particularly true of the phosphoanhydride systems. Fortunately, several groups are working towards more convenient methodologies for the preparation of phosphoesters, anhydrides and their analogues, and details of these efforts can be accessed elsewhere [55, 56•, 57, 58, 59, 60•, 61, 62, 63•, 64, 65•, 66, 67, 68•• and 69]. Heavy isotope kinetic studies have proven extremely enlightening, however, the measurement of these extremely small effects (even in best case scenarios) remains the preserve of a few specialist groups. Combinations Florfenicol of experimental approaches with computational methods are also allowing more rigorous, quantitative assessment of observed kinetic data, where interpretations of kinetic results can often be complex. In summary, synthetic methodology, in tandem with kinetic measurements and computational dissection are providing enzymologists with an enhanced toolbox for the determination of phosphoryl transfer mechanisms.
