We next determined the PPI network for A. thaliana by mapping the each eggNOG ID, used in the pan-plant network, to a TAIR locus ID [8]. By applying WCC and comparing the results clusters against the plant gold standard, we predicted 144 new protein complexes. Interestingly, 39.58% of these new complexes show GO semantic similarity of MF category equal to 1, suggesting coordinated functions of the involved proteins (see Supplementary Table 6). However, it has already been shown that functional modules may perform different molecular functions, but could be involved in the same process and can take place in the same organelle [62], [63]. Therefore, we also investigated the new clusters that obtained maximum GO semantic similarity (of 1) for the BP and CC categories, but showed lower GO semantic similarity based on the MF category. Consequently, we considered 8.33% of the new predicted complexes as functional modules (see Supplementary Table 7). To evaluate the performance of different network clustering approaches, we used two E. coli, four S. cerevisiae, and two H. sapiens PPI networks. All PPI networks are edge-weighted except one from E. coli. The S. cerevisiae PPI networks, including Gavin [4], Collins [53], Krogan Core, and Krogan Extended [54], were obtained experimentally, and the weights (in the range between zero and one) denote the reliability of each interaction. In the Collins PPI network, the interaction weights are based on purification enrichment score, while in the Gavin PPI network, the weight indicates the socio-affinity index that measures the affinity between proteins. The socio-affinity index calculates the log-odds of how many times pairs of proteins are observed together as preys, or a bait and a prey in the network. In the Krogan PPI network, each interaction is assigned a probability based on the integration of mass spectrometry scores. This network has two versions, the Krogan core contains highly reliable interactions (probability ≥ 0.273), the Krogan extended network includes more interactions of smaller reliability (probability ≥ 0.101). In addition, we used the up-to-date H. sapiens PPI networks obtained from STRING [55] and PIPS [6]. In the STRING network, the score on each interaction does not indicate the strength but the confidence of an interaction, i.e., given all available evidence, denoting how likely it is that the interaction is real. Two different types of the score are available in the STRING dataset, i.e. combined score and sub-score. In this study, we considered the combined score that is supported by several types of evidence, namely: Conserved neighborhood, Gene fusions, co-expression, phylogenetic co-occurrence, database imports, large-scale experiments, and Literature co-occurrence. The interaction score in the PIPS network corresponds to the posterior odds ratio of interaction computed based on a naïve Bayes network [71]. Intuitively, the score indicates the likelihood of the interaction between pairs of proteins given the evidence. In the prediction of interactions, several features are considered, such as: expression data, protein domains, subcellular localization, and co-occurrence of domains. Therefore, to consider more reliable protein interactions into our study, we set the cut-off score of 999 and 25 for STRING and PIPS PPI networks, respectively. Moreover, two E. coli PPI networks that are obtained from [5], [7] are used in this study. For simplicity, we named the PPI networks the same as the corresponding first author Babu and Cong throughout the paper. The protein interactions in Babu network inferred experimentally from affinity purification mass spectrometry (APMS). Later, they applied an integrative statistical framework on inferred interactions to obtain a confidence score for each PPI. The protein interactions in Cong network are predicted by utilizing evolutionary signatures in protein sequence and structure.

Whether you are a novice or competitive athlete, when you undertake any exercise, you want to take preventative measures to reduce muscle damage. PanelA shows the hyperbolic running speed–time relationship plotted for the current (as of March 2019) world records from 1500m to 5000m (in blue, records held by different athletes) and the personal best times over the same distances run by an individual elite distance runner (Eliud Kipchoge, EK, in red). PanelB shows that the hyperbolic curve constructed for the world records from 1500m to 5000m (in blue, same data as in PanelA) does not provide a good fit to world record performances over shorter (100m to 800m) or longer (10,000m to the marathon) distances. Thus, the hyperbolic relationship is valid for events which take between ~2min and perhaps 15–20min to complete. The linear transformation of the hyperbolic relationship is shown in PanelC (distance–time plot where the slope of the linear regression line gives critical speed, CS, and the intercept gives the curvature constant, D′) and PanelD (speed‐1/time plot where the slope gives D′ and the intercept gives CS). The CS and D′ estimates from the three equations, with the associated standard errors of the estimate, are shown at the foot of the figure. Mounting evidence based on these PPI networks and gold standards has pointed out that the existing methods tend to predict dense and large protein complexes; however, the vast majority of real protein complexes are small and sparse [32]. In addition, comparative analyses have demonstrated that these approaches are not able to predict high-confidence clusters and suffer from small recall [33]. This observation has led to the design of algorithms to identify sparse [34], [35] and small complexes [36], [37], which have slightly improved the recall of protein complexes. Yet, these algorithms depend on multiple parameters, which render it difficult to gauge the performance in absence of optimal parameter values for different combinations of PPI networks and gold standards. It was recently shown that a parameter-free approach, that models protein complexes as biclique spanned subgraphs, outperforms the existing, seminal approaches [38] and allows for the identification of both dense and sparse clusters; however, only in unweighted networks of limited size. Despite the widespread use of the Seahorse Bioanalyzer technology, acquisition of reliable data requires effective normalization strategies to correct for cell density. Multiple normalization methodologies have been used with varying degrees of acceptance by the research community. Examples include normalization to post-assay protein harvest or post-assay cell counting, normalization to pre-assay cell counting 22, or normalization via one of a variety of chemical colorimetric or fluorometric readouts (e.g., MTT, ATPGlo, WST-1). Specifically in a recent study employing small-interfering RNA (siRNA)/short-hairpin RNA (shRNA) screening, Hoechst nuclei staining coupled with automated nuclei count was demonstrated to have better performance than other normalization methods 23. Indeed, this strategy has been recently incorporated into the Seahorse pipeline to more adequately control for cell number with the merger of BioTek Cytation5 and Seahorse XF assay platforms 24. Herein, we optimize and extend this previous work, as nuclei staining can also be applied to determine cell cycle distribution 25, 26; an important cellular characteristic that affects bioenergetics. Importantly, mitochondrial bioenergetics have been previously shown to coordinate with cell cycle dynamics 27, 28, further supporting the use of nuclei counterstaining in conjunction with the metabolic flux assay. A 2020 review showed that supplementing with turmeric extract at a dose between 150mg – 1500mg per day before and during exercise and up to 72 hrs post exercise improved performance by reducing exercise-induced muscle damage and reducing inflammation caused by physical activity.

While we have reviewed evidence supporting CP as the bona fide demarcator of the maximal metabolic steady state, it is essential that great care is taken in its estimation (Mattioni Maturana etal. 2018; Muniz‐Pumares etal. 2019). There are two methods by which CP can be assessed: the ‘conventional’ approach in which CP is modeled from a series of severe‐intensity ‘prediction trials’ performed to the limit of tolerance at different speeds or power outputs (Monod and Scherrer 1965; Poole etal. 1988); and the 3‐min all‐out test in which, as the name implies, subjects exercise maximally for 3min with the end‐test power representing the CP and the total work done above CP representing the W′ (Burnley etal. 2006; Vanhatalo etal. 2007). If the CP is estimated using the conventional approach, important considerations include the number of trials and their duration (Hill 1993; Bishop etal. 1998; Triska etal. 2018). It is essential that subjects give their maximum effort in each trial and that cadence is consistent across all trials. Ideally the shortest trial should be 2–3min and the longest should be more than 10 but no longer than 15min (Hill 1993; Vanhatalo etal. 2011a). It has been recommended that there should be at least a 5min difference between the shortest and longest trials (Bishop etal. 1998) but the goodness of hyperbolic fit is improved by making the range of times to exhaustion as broad as possible (i.e., 8–12min) within the severe‐intensity domain. The precise duration of the prediction trials is of secondary importance to the attainment of V ˙O 2max, but it is unusual for V ˙O 2max to be attained if exercise duration is shorter than 1–2min or longer than 15–20min (Hill etal. 2002; Vanhatalo etal. 2016). V ˙O 2 should be measured during each trial to verify attainment of V ˙O 2max, with this typically defined as the end‐exercise V ˙O 2 exceeding 95% of the V ˙O 2max measured during ramp incremental exercise, to allow for biological and methodological day‐to‐day variability (Katch etal. 1982). Then, I called his phone number, and waited on hold for about 40 minutes while listening to the same recording over and over. Finally, I gave up on that attempt. Then, a couple of days later, I tried again, but this time, I followed prompts to speak with a rep about receiving a return lable.

Next, we aimed to determine new protein complexes in PPI networks from plant. To this end, we used the recently assembled pan-plant PPI network by using data from co-fractionation mass spectrometry from 13 plant species; the resulting protein interactions are scored based on the likelihood of physical interaction between two proteins [8]. Here, we considered the high-confidence interactions (with scores greater than 0.5), and used the same gold standard of plant protein complexes (see Supplementary Table 1).
