“The proposal to formally designate an Anthropocene Epoch has become a hot issue over the last several years, championed or contested by the public, media, and scientists. The response has been powerful enough to garner the cover story on the May 26, 2011, edition Androgen Receptor Antagonist of The Economist, numerous articles MK-1775 concentration in top-tier academic journals such as Science (e.g., Balter, 2013 and Cooper et al., 2012), Nature (e.g., Crutzen, 2002, Crutzen, 2010 and Jones, 2011), and Proceedings of the National Academy of Sciences (e.g., Beerling et al., 2011 and Smol et al., 2005), and the founding of this journal dedicated to the topic. The designation of an Anthropocene could be a milestone

in the geological and social sciences, an idea that has been building GNA12 for 140 years since Italian geologist Antonio Stoppani first proposed an “anthropozoic era” in AD 1873 (see Crutzen, 2002 and Goudie, 2000: 4–5). With a world population of more than 7.2 billion, it is difficult

to argue that we are not currently living in an “age of humans.” The acceleration of CO2, CH4, and N2O in atmospheric records (Crutzen and Steffen, 2003), the explosion in global human populations (McNeill, 2000), anthropogenic land surface clearance (Ellis, 2011, Ellis et al., 2013 and Vitousek et al., 1997), the crisis of our world’s oceans from overfishing, ocean acidification, and pollution (Jackson et al., 2001 and Pauly et al., 1998), the appearance of radio-nucleotides from atomic detonations (Crutzen and Steffen, 2003), and much more all provide ample evidence that human alterations of Earth’s natural systems have become pervasive and ubiquitous. The major point of contention, at least among the geoscientists, has been the starting date for the Anthropocene (for an alternate view see Crist, 2013). Most have proposed to either divide the Holocene – already the shortest geologic epoch beginning just 11,700 calendar years ago – into a smaller temporal unit or do away with it altogether (Doughtry et al., 2010; see Foley et al., 2014 for a brief summary).

, 2012) lacks supporting evidence. Human skeletons in the Peruvian Amazon, Santarem area, and middle Orinoco show little or no isotopic effect of maize until late prehistory ( Roosevelt, 1989, Roosevelt, 1997 and Roosevelt, 2000:482–485), when open-field maize cultivation is recorded in floodplains

and wetlands. The sun-loving grass maize (Zea mays, Poaceae) was an introduced cultigen (no wild relatives are known for South America), AUY-922 in vitro whereas most Native Amazonian cultigens tend to be grown in mixed slash and burn fields, like manioc (Manihot esculenta, Euphorbiaceae) ( Olsen and Schaal, 1999), or in mixed orchards of the domesticated peach palm (Bactris gasipaes) and fruit trees that, though not domesticated, were cultivated ( Clement, 1999, Clement et al., 2010, Mora-Urpi et al., 1997 and Smith et al., 2007). Although Amazonia’s most important crop plant was the shrub Tenofovir purchase manioc, the second most important domesticate original to Amazonia was the peach palm, and the majority of other plants cultivated by Amazonians are woody trees ( Clement et al., 2010:74). Prehistoric earthworks are another important human alteration to Amazon landscapes (Roosevelt et al., 2012 and Roosevelt, 2014). Amazonian mounds were built to elevate surfaces for residential, social, ritual, symbolic, defensive, transportation,

or agricultural purposes. Some raised settlements

above flood level, creating ponds with their borrow pits. Some seem to make sociopolitical or religious statements: to raise some residences above others, to bring cemeteries into more prominence, or to create ritual precincts and shrines. Transportation structures range from Adenosine triphosphate causeways to ritual promenades and channels for boats. Agricultural works range from raised field surfaces to drainage ditches. While residential mounds are packed with rich, dark refuse, other structures, facilities, and especially socio-technic constructions can be almost devoid of refuse except for rare, cached offerings. Platform mounds for structures also can be almost devoid of artifacts except for their upper surfaces, as can raised fields. But all these structures include some kind of macroscopic or microscopic specimens and chemical and sedimentological evidence of their origins and use as human artifacts. One of the earliest and largest examples of extensive terra firme earthwork systems are those of the Faldas de Sangay culture of Ecuador in the western Amazon ( Porras, 1987, Rostain, 2010, Rostain, 2012, Salazar, 1998 and Salazar, 2008). Lying below the recently extinct volcano Sangay, it is a hilly tropical forest area drained by the Napo and its tributaries. Most of the current surfaces are quite rich tropical soils derived from the weathering of volcanic rocks and ash.

However, cells were ERα deficient, which is in accordance with CFTR modulator Iwanari et al. [22]. Thus, to analyse receptor interaction in detail, the study

was performed in hERα overexpressed HepG2 cells after transient transfection. Though for some less potent AhR agonists such as 3-methylcholanthrene a direct activation of ERα resulted in an estrogenic response, TCDD has been reported to be an indirect ERα inhibitor and exert anti-estrogenic effects. [6], [11], [12], [13] and [14]. Previous studies on the AhR/ER cross-talk mainly focused on investigating these effects in breast cancer cell lines. However, the liver is one of the major target organs of TCDD’s toxic action mediated via AhR. Thus, the focus of this research work was put on the liver since the liver is also one major site of estradiol metabolism and the ERα is highly expressed [28]. In HepG2 cells TCDD led to anti-estrogenic activity by reducing E2-mediated ERα signalling in the ERE-regulated reporter gene activity assay only in the presence of ERα. The complete ER antagonist ZK 191 703 Selleck BI2536 totally blocked the estrogenic response and application of the partial AhR antagonist α-naphthoflavone [29] reversed TCDD’s anti-estrogenic repression of AhR-dependent reporter gene activity in HepG2 cells. Thus, these results support the hypothesis that the ligand-activated AhR interacts with ERα and represses E2-bound ERα-mediated transcription

upon ERE similarly to what is reported in hormone-dependent cell lines [6], [7] and [30]. The activation Erastin chemical structure of AhR by TCDD is supposed to be a crucial step in the interaction of AhR/ER, since various experiments in AHR-deficient cell models have failed to demonstrate the modulation of ERα functional activity. In multiple ER-positive breast and endometrial cancer cells TCDD was shown to be strongly

anti-estrogenic, such as in MCF-7 breast cancer cells, but also in ER-negative Hepa-1 mouse hepatoma cells transfected with an ERα expression vector [3], [10], [30], [31] and [32]. In contrast, in a non-functional AhR mutant Hepa-1 cell line TCDD failed to exert an effect on E2-dependent ER signaling, suggesting an interaction between AhR and ER pathways [30]. Similarly, the expression of E2-responsive genes/proteins and their related activities was decreased in multiple ER-positive breast and endometrial cancer cells after co-treatment of E2 and TCDD and the identification of so-called inhibitory XREs (iXREs) in the critical promoter regions of these E2-responsive genes provided further evidence for the inhibition of E2-dependent target genes via interaction with the activated AhR [3], [31], [32], [33], [34] and [35]. Reciprocally, HepG2 cells transiently transfected with a XRE-luc reporter showed enhanced TCDD-mediated luciferase activity upon E2 treatment only in the presence of constitutively over-expressed ERα⋅ TCDD alone resulted in increased luciferase activity independent of the ERα.

Therefore, it is possible to recognize changes in geographical distribution of seaweeds along the coast in the northwestern

Pacific Ocean due to global warming. Most of Sargassum species mature in early spring to early summer around Japan. When they become large around the mature season, some of them have been sometimes detached from the bottom by strong waves ( Yoshida, 1963). Sargassum species can float due to their vesicles after being detached. While some are stranded on the beach, the others are transported to offshore waters by surface currents due to positive buoyancy produced by many vesicles. Floating Sargassum species are called as Nagare-mo floating seaweeds or seaweed Cobimetinib cell line rafts in Japan ( Yoshida, 1963). Floating seaweeds are commonly found in Japanese waters ( Yoshida, 1963) from spring to early summer, as in the Sargasso Sea. In this particular area, floating

seaweeds spend their entire floating-life stage in a vegetative reproductive state ( Parr, 1939). Floating seaweeds play key ecological roles in Sunitinib cell line offshore waters as well, as they play host to attaching or accompanying flora and fauna (Thiel and Gutow, 2005). Hence, floating seaweeds constitute moving ecosystems (e.g., Cho et al., 2001 and Abé et al., 2012). Thus, they serve as means of dispersal for littoral animals such as intertidal animals (e.g., Ingólfsson, 1995). With regard to fisheries, they are spawning habitats for flying fish (Ichimaru et al., 2006), Japanese halfbeak and Pacific saury (Cololabis saira Brevoort) ( Ikehara, 1986). They also serve as nursery habitats for larvae and juveniles of some commercially important pelagic fish species ( Ikehara, 2006), such as yellowtail

(Seriola quinqueradiata Temminck & Schlegel) ( Yamamoto et al., 2007) or jack mackerel (Trachurus japonicus Temminck & Schlegel) ( Senta, 1965), which spawn in the East China Sea ( Fig. 1). Recent studies suggested that the origin of floating seaweeds in East China Sea consisting of only one species, Sargassum horneri C. Agardh, is Chinese coast, especially off Zhejiang Province ( Komatsu et al., 2005, Komatsu et al., 2013 and Mizuno et al., 2013) because this species is not distributed south of Kyushu Island and Ryukyu Archipelago ( Komatsu et al., Farnesyltransferase 2007, Komatsu et al., 2009 and Filippi et al., 2010). Consequently, investigating change in spatial distribution and abundance of floating seaweeds consisting of S. horneri and spawning zones of yellowtail defined as surface water temperatures in this specific area is of primary interest for fishery purposes. S. horneri is one of important seaweed aquaculture species as food in Japan and Korea (Ajisaka, personal communication). Spatial distribution of this species is very wide from Hokkaido Island in a boreal zone to north Kyushu Island facing East China Sea and central Honshu Island facing the Pacific Ocean in a temperate zone.

Unlike the closely related Cdkn1a and Cdkn1b, Cdkn1c is primarily expressed during mouse embryonic selleck inhibitor development [35] and is also believed to have a role in the developing nervous system, promoting differentiation 36, 37 and 38], regulating

corticogenesis 39 and 40], and maintaining adult neural stem cell quiescence [41]. Additionally, but separate to its cell cycle role, Cdkn1c was shown to co-operate with Nurr1 to promote the proliferation of midbrain dopaminergic neurons [42]. Although no systematic examination of Cdkn1c on behaviour has been performed, probably because of the lethality of constitutive knockouts [43], expression of this gene is sensitive to manipulations of the pre-natal and post-natal environment 33, 44, 45• and 46]. In particular, maternal diet whilst pregnant and maternal care as indexed by licking and grooming, Gemcitabine chemical structure both lead to increased expression of Cdkn1c in the brains of mice and rats respectively. This in turn correlates with changes in the dopamine system and motivated behaviour. As yet there has been no demonstration of a causal, mechanistic link between Cdkn1c expression and these neural change; or indeed if the imprinting of Cdkn1c is altered in anyway. Nevertheless, these studies provide a tantalising hint that imprinted genes expressed in the brain may be sensitive to changes in the pre-natal and post-natal periods. The range of

behaviour influenced by imprinted genes is expanding. In addition to

previously established genomic imprinting effects on the interaction between mother and offspring 47 and 48] and aspects of cognition [6], recent developments Fossariinae have also demonstrated roles in mediating social dominance [22], circadian rhythm 20 and 49], and motivational behaviours 45• and 46]. A greater understanding of variety of behaviours influenced will no doubt help address the fascinating debate about how and why this group have evolved to influence brain function at all [28]. Adding to this discussion, and possibly of greater interest to the non cognoscenti, is the increasing evidence that change in the epigenetic regulation of imprinted genes may be a mechanism by which the effects of the environment on behaviour, particularly the pre-natal and early post-natal environment, are mediated.

“Current Opinion in Behavioral Sciences 2015, 2:34–38 This review comes from a themed issue on Behavioral genetics Edited by William Davies and Laramie Duncan doi:10.1016/j.cobeha.2014.07.003 2352-1546/© 2014 Published by Elsevier Ltd.

The purified protein size (∼52 kDa) was determined via sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and its concentration was measured using spectrophotometry (NanoDrop ND-1000). Five ice samples were prepared. All samples contained a 7 g/l NaCl solution, which is a salt concentration comparable with measurements in Antarctic basal ice [23]. IBPs were added to three samples to monitor concentration effects and the difference between naturally secreted extracellular protein (ECP) and purified

recombinant IBP (rIBP). The ice sample containing a crude preparation of the IBP consisted of 7 g/l NaCl solution with 10 μg/ml of 3519-10 ECP (>30 kDa with an unknown IBP fraction) and will hereafter Selleck Fluorouracil be referred to as ice with ECP. The two samples containing 7 g/l NaCl and 2 and 4 μg/ml recombinant IBP will be referred to as ice with rIBP(2) and ice with rIBP(4) respectively. Two control samples were also prepared: (i) the ice control, a 7 g/l NaCl solution without protein and (ii) ice with bovine serum albumin (BSA), a 7 g/l NaCl solution with 10 μg/ml BSA. The second

control was used to examine ice binding activity from colligative effects due to the presence of a similar macromolecule, since BSA is of similar size (∼64 kDa) to buy Bleomycin the 3519-10 IBP (∼52 kDa), but does not exhibit ice binding activity. All samples were prepared by filling 13 mm OD (11.7 mm ID) standard NMR tubes with solution, placing them in a polystyrene sample holder, insulated on the sides and bottom, and freezing them in a Revco ULT-750 chest freezer at −13.5 °C. To ensure hexagonal ice crystal structure consistent between sample types, multiple samples of each concentration were frozen and inspected by eye and those with cloudiness and/or air bubbles which would indicate

supercooling and subsequent rapid freezing were discarded. Samples were transferred from the chest freezer in a cooler filled with gel freezer packs stored in the same freezer. Transfer time of the ice from the cooler to being in the RF coil with cold O-methylated flavonoid nitrogen gas flow was minimized to ∼3 min. The MR magnet electronics were always pre-cooled at the set temperature before sample insertion and the set temperature equilibrized within ∼5 min. The samples were allowed to equilibrate at the set temperature for 45 min before measurements were performed. Samples were analysed via NMR at multiple time points over 1800 h, and stored in the freezer at −13.5 °C in between NMR measurements. NMR measurements were performed on a Bruker DRX250 spectrometer with a 5.8 T superconducting vertical wide bore magnet and Micro2.5 gradient imaging probe capable of producing maximum gradients of 1 T m−1. Temperature was controlled via flow of cooled nitrogen gas along the vertical axis of the NMR sample tube using a Bruker variable temperature control unit. The 13 mm OD (11.

These data show that 2 h exposure of S. cerevisiae to JBU interferes on the energy metabolism of the cells, with no visible changes in membrane permeability. As the exposure of C. tropicalis ( Fig. 3, panel C), P. membranisfaciens, C. parapsilosis and K. marxiannus cells to JBU for 24 h caused membrane permeabilization, monitoring of JBU-treated S. cerevisiae for a longer time is required to evaluate if progression of antifungal effect would

eventually lead to cell death. Hydrolysis of JBU with papain produced fungitoxic peptides smaller than 10 kDa. Five of these peptides were identified by mass spectrometry and none of them match putative selleckchem antifungal domains of JBU homologous to other plant antifungal proteins. At this point, two possibilities should be considered: these peptides are not associated with antifungal(s) domain(s) of JBU, or the JBU antifungal(s) domain(s) learn more are unlike any other fungitoxic proteins already known. One of these peptides contained part of the N-terminal sequence of the insecticidal peptide Jaburetox-2Ec. Becker-Ritt et al. [7], reported that Jaburetox-2Ec did not affect the micellar growth of phytopathogenic fungi, including that P. herguei. In that study, the peptide was added to the medium at a lower dose (0.57 μМ), after 16 h of culture, at a later stage of germination of the spores. Here, Jaburetox was added simultaneously with the

spores, leading to inhibition of germination and growth, and delaying development of hyphae. This result indicates that besides its Edoxaban insecticidal activity, this internal peptide of C. ensiformis urease is also antifungal, affecting the early stages of development of the mycelium, a step also susceptible to ureases [7]. The variations in methodology used in the two studies may have influenced the different results obtained. The time

course and characteristics of the fungitoxic effects indicated similar antifungal mechanisms for JBU and Jaburetox, probably based on the ability of these polypeptides to insert in membranes, altering the cell permeability. The antifungal activity of Jaburetox on yeasts required 2–3 times larger doses as compared to the holoprotein JBU, indicating the possibility that other protein domains are involved in this activity. Becker-Ritt et al. reported the antifungal activity of the two-chained urease from H. pylori. Bacterial ureases lack part of the amino acid sequence (the N-terminal half) of Jaburetox, which in single-chained plant ureases corresponds to a linker region between bacterial subunits. This fact strongly suggests that other antifungal domain(s) besides the region corresponding to the entomotoxic domain are present in ureases. The discovery of new antifungal agents becomes increasingly important due to the increasing number of cases of invasive mycoses.

The pellets so obtained were then suspended in 0.01 M MgSO4 solution and treated with an equal volume of test samples. Aliquots were withdrawn at regular intervals from 0 to 6 h, suitably diluted and plated to assay the colony forming ability of the cells. The same onion bulbs exposed to the test samples at varying concentrations in Allium cepa test were used for chromosomal aberration test. Aquaguard water was used as negative control and MMS (methyl selleck screening library methane sulphonate) as positive control. Elongated roots

from the onion bulbs were allowed to grow for 48 h. Root tips were then harvested and fixed in absolute alcohol and glacial acetic acid (3:1) for about 30 min. After this root tips were kept in 1% iron alum solution for 3 -12 h. This was followed by slide preparation using acetocarmine as the stain. After the preparation of permanent slides the chromosomal aberrations were observed through microscope calculated by the established procedure [10]. The phtotoxicity test with Allium cepa as http://www.selleckchem.com/products/Adrucil(Fluorouracil).html system was carried out for Mathura refinery waste

water (RWW) and Aligarh waste water (AWW). The dose response relationships of the above mentioned waste waters following 2 days exposure have been depicted in Figure 1. The IC50 values of RWW and AWW were recorded to be 0.14X (i.e. 0.14 times concentration of the test water) and 0.10X respectively. E.coli survival assay was done to assess the genotoxic effect of RWW and AWW on various E.coli strains. The survival pattern of E.coliK12 strains exposed to 1X concentration of RWW upto 6 h is shown in nearly Figure 2. The maximum survival was shown by AB1157 and it was recorded to be 77% after 6 h treatment. AB2494 strain exhibited 20% survival whereas AB2463 strain showed only 4% survival following 6 h exposures. The minimum survival was recorded for AB2480 and that was 1% with the test sample under the same conditions. Survival of E.coliK12 strains exposed to 1X concentration of AWW upto 6 h is depicted in Figure 3. The maximum survival was displayed by AB1157 strain and that was recorded

to be 55% after 6 h treatment. AB2494 strain exhibited 19% survival while AB2463 strain showed only 11% survival after 6 h exposure. The minimum survival was exhibited by AB2480 to be 3% after 6 h treatment. Chromosomal aberration test was also performed to analyse the genotoxic potential of RWW, AWW and test heavy metals. Changes in the mitotic index (MI) and abnormality pattern in the Allium cepa system caused by Mathura refinery waste water (RWW) are listed in Table 1. A lower MI value (39.1) for RWW treated A.cepa cells compared with untreated control (44.7) was recorded which attained a value of 42.8 when the treatment was given in the presence of mannitol exhibiting a recovery of 8.6%. The aberration index of RWW was 14.7% as compared to negative control to be 2.6% and it showed around 50% decline in presence of the OḢ radical scavenger.

Images of BEAS-2B cells and

HBEpCs exposed to MWNT-7 are shown in Fig. 3. MWNT-7 was observed near the nuclei and cytoplasm in BEAS-2B cells in Ham’s F12 and HBEpCs in SFGM. However, BEAS-2B cells in SFGM showed low internalization of MWNT-7, and some MWNT-7 adhered to the cell surface. We evaluated cytokine secretion by BEAS-2B cells incubated in Ham’s F12 and SFGM as well as HBEpCs incubated AZD6244 in SFGM in response to MWNT-7. Although IL-6 secretion by untreated BEAS-2B cells in Ham’s F12 and untreated HBEpCs was sufficient for detection (33.8 ± 5.0 and 5.1 ± 0.5 pg/ml, respectively), secretion of IL-6 by BEAS-2B cells in SFGM was not detected (under 1.6 pg/ml). Exposure to MWNT-7 increased CT99021 chemical structure IL-6 secretion by BEAS-2B cells in Ham’s F12 and HBEpCs (Fig. 4a). However, the degree of the increase and the MWNT-7 concentration that stimulated the maximal increase were different: BEAS-2B cells in Ham’s F12 and HBEpCs showed a 20-fold and 2-fold upregulation in response to 10 μg/ml and 1 μg/ml MWNT-7, respectively. Moreover, IL-6 secretion in response to 50 μg/ml MWNT-7 was the same as that in response to 10 μg/ml MWNT-7 in BEAS-2B cells in Ham’s F12, but decreased to the level of the control in HBEpCs. IL-6 secretion by BEAS-2B cells in SFGM was lower than the detectable limit when the cells were exposed

to MWNT-7, even at the maximum concentration. IL-8 was secreted by both cell types under the untreated condition, and the concentration was on the order of HBEpC > BEAS-2B in SFGM > BEAS-2B in Ham’s F12 (814.1 ± 78.9, 260.2 ± 18.6 and 169.3 ± 22.0, respectively), (Fig. 4b). Upon exposure to 10 μg/ml MWNT-7, BEAS-2B cells in SFGM did not demonstrate a change in secretion, whereas other cell conditions produced increased IL-8 secretion. However, secretion in response to 50 μg/ml MWNT-7 did not

show a further increase. The increase was more pronounced in BEAS-2B cells in Ham’s F12 than in HBEpCs. Internalization of MWNT-7 by BEAS-2B cells in Ham’s F12 and HBEpCs in SFGM was suppressed by chlorpromazine, which is a clathrin-mediated endocytosis inhibitor, and indomethacin, which is a Tacrolimus (FK506) caveolae-mediated endocytosis inhibitor. The cells showed extensive internalization of MWNT-7 for 2 h without the inhibitors, whereas cells pre-treated with the inhibitors showed little internalization of MWNT-7 and some MWNT-7 on the plasma membrane, as determined using fluorescence microscopy (Fig. 5a). The amount of internalized MWNT-7 was determined using the SSC relative ratio in BEAS-2B cells in Ham’s F12 and HBEpCs in SFGM treated with or without the inhibitors after exposure to MWNT-7 for 2 h, as shown in Fig. 5b and c. The SSC relative ratio for BEAS-2B cells that internalized MWNT-7 in SFGM is also shown in Fig. 5b. The amount of MWNTs internalized by BEAS-2B cells was significantly lower in SFGM medium than in F12 (Fig. 5b).

Characteristics of interest for our study population of 81 children and adolescents are shown in Table II. The minimum and maximum ages of the participants AZD5363 in vivo were 0.70 and 20 years, respectively. There were 10 patients with single kidney and 7 with a kidney transplant. The primary diseases that resulted in a kidney transplant were nephropathic cystinosis (4 cases), kidney dysplasia (2 cases), and autosomal recessive polycystic kidney disease (1 case). Five patients with Wilms tumor, 1 with mesoblastic nephroma, and 1 with Langer Giedion syndrome had single native kidneys after a unilateral nephrectomy performed for clinical

care. The values of mGFR and the 14 corresponding eGFR values are shown in Table III. The mean mGFR for the 81 subjects was 77.9 ± 38.8 mL/min/1.73 m2. The median and IQR (P25, P75) were 77.8, 52.0, and 96.0 mL/min/1.73 m2, respectively. The numbers of patients with mGFR ≥90, 60–89, 30–59, and <30 mL/min/1.73 m2 were 25, 31, 17, and 8, respectively. The calculated eGFR values were highly correlated (P < 0.001) with the mGFR value. However, 3 equations based on Scr alone, 1 based on Scys, and all 4 based on combinations of both demonstrated no significant difference from the mGFR values (P > 0.05).

These same 8 equations also had lower bias compared with the others selleck screening library in the Bland-Altman analysis. Table IV lists the performance of the selected 8 equations determined by calculating accuracy, bias, and precision. All had low bias, but 3 multivariate Dichloromethane dehalogenase equations based on a combination of Scr and Scys, Schwartz et al4 and 11 and Chehade et al18 had the highest accuracy with approximately 60% of P15 and 80% of P30. Fig 1 shows the agreement between eGFR and mGFR for these 3 multivariate equations. There was good agreement across the GFR range from low to high, especially

for equations of Schwartz et al.4 and 11 On the basis of the results mentioned previously, the 3 multivariate equations had the best performance among all eGFR equations. We analyzed their applicability in 10 patients with a single kidney, 7 with kidney transplant, and 11 short stature patients with height Z-score ≤−2.5 ( Table V). From the Wilcoxon test, there was no significant difference between eGFR and mGFR in patients with single kidney, kidney transplant, and short stature (P ≥ 0.05). The values of the 3 equations also showed acceptable bias and precision in the Bland-Altman analysis. Accurate assessment of GFR is essential for interpreting the symptoms, signs, and laboratory abnormalities that may indicate kidney disease, for monitoring side effects of therapeutic drug use, and for detecting and managing CKD and assessing its prognosis, among others.
