Abstract
This study explored biochemical parameters of blood in workers operating in the main workshops at the Ust-Kamenogorsk Titanium and Magnesium Plant: magnesium (Mg) workshop (furnace operator, chlorinator operator, and electrolyzer operator), titanium tetrachloride workshop (mill operator and titanium (Ti) production operator), and Ti sponge workshop (reduction furnace operator, knockout operator, and crushing machine operator). The control group consisted of 112 male workers, whose duties were not related to similar occupational hazards (plumbers, electricians, janitors cleaning the administrative building, security guards, and carpenters). The activity of gamma-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, lactate dehydrogenase, cholinesterase, alkaline phosphate, and α-amylase and the concentration of serum calcium, Mg, phosphorus, and chloride ion were measured. To clarify the nature of pathological changes that occur in the body of mammals under the influence of toxic gases and dust, this study also included 130 sexually mature, white female rats. Animals and workers were exposed to examination of the same indicators. Changes in test results of enzymes and minerals indicated a negative impact that harmful production factors may have had on the bodies of workers. Findings showed significant fluctuations in enzyme and mineral blood profiles of workers as compared to controls. In the test animals, changes in the enzyme activity and mineral blood composition were as diverse as in the workers. These findings will be useful when identifying markers of a negative impact of harmful substances in an industrial workplace and when developing measures to prevent employees from developing an occupational disease.

Abstract
OBJECTIVE The range of normal serum alkaline phosphatase is not well defined. We used data from the National Health and Nutrition Examination Survey from 2009 to 2016 to generate normal ranges for a racially diverse sample of healthy adults. METHODS Respondents 18 years or older were included. Conditions known to elevate alkaline phosphatase were cause for exclusion. Alkaline phosphatase was measured using a colorimetric method based on standardised National Health and Nutrition Examination Survey protocols. Because alkaline phosphatase values were not normally distributed, log transformation was used. We calculated upper limits of normal (97.5 percentile), stratified by sex and race/ethnicity, and 90% CIs for the upper limits of normal. RESULTS 1199 respondents (673 female, 526 male) had body mass index from 18.5 to less than 25. Upper limits of normal were highest among Hispanics (123.2 IU/L (90% CI 110.2 to 136.7) for females; 123.8 IU/L (90% CI 112.0 to 135.1) for males), followed by African Americans (109.9 IU/L (90% CI 97.3 to 122.4) for females; 116.3 IU/L (90% CI 105.0 to 126.1) for males) and whites (97.1 IU/L (90% CI 91.0 to 103.4) for females; 109.6 IU/L (90% CI 102.1 to 116.3) for males). Asian American/Pacific Islander respondents had the lowest results: 93.8 IU/L (90% CI 88.2 to 99.5) for females and 95.3 IU/L (90% CI 88.1 to 102.1) for males. CONCLUSIONS The upper limit of normal alkaline phosphatase varies by race/ethnicity in a large US sample with body mass index of 18.5<25.

Abstract
The Japan Society of Clinical Chemistry reference method (JSCC method) is used to measure
alkaline phosphatase (ALP) activity only in Japan. Other countries use the International
Federation of Clinical Chemistry and Laboratory Medicine (IFCC) reference method to
measure ALP activity. Since April 2020, human medical institutions in Japan have been
gradually switching to the IFCC method. However, it is unclear whether the supply of
reagents required for the JSCC method will be steady in the future. Additionally, the
comparison of the performances and accuracies of these two methods for measuring ALP
values remains uncertain in several animal species. In this investigation, we measured
canine ALP activity using both methods and developed a formula to interconvert the two
resulting values. The regression formula for ALP values measured using the modified JSCC
(x) and IFCC (y) methods was determined as log10 y=0.960 log10
x−0.395 (r=0.997). However, the correlation between values based on JSCC and IFCC methods
can change depending on the composition of ALP isozymes. Therefore, the developed formula
can currently serve as a provisional strategy in calculating ALP levels. Nevertheless,
this formula might avoid confusion in the clinical field during the transition from the
JSCC to the IFCC method when both measurement values co-exist.

Abstract
The current study aimed to investigate linagliptin for its potential role in the prevention of liver fibrosis progression. Balb-C mice were randomly allocated into five groups (10 each): (i) control; (ii) mice were injected intraperitoneally with 50 μL carbon tetrachloride (CCl4) in corn oil in a dose of 0.6 μL/g three times per week for four weeks; (iii) linagliptin was administered orally in a daily dose of 10 mg/kg simultaneously with CCl4; (iv) silymarin was administered orally in a daily dose of 200 mg/kg concomitantly with CCl4; and (v) only linagliptin was administered. Hepatic injury was manifested in the CCl4 group by elevation of biochemical parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP)), and hepatic fibrosis was evident histopathologically by increased METAVIR score and immunostaining expression of alpha-smooth muscle actin (α-SMA), as well as increased liver tissue oxidative stress parameters, transforming growth factor-β1 (TGF-β1), and mammalian target of rapamycin (mTOR). Linagliptin was able to stop the progression of liver fibrosis, evident histopathologically with reduced METAVIR score and α-SMA expression. The possible mechanism may be via suppression of oxidative stress, TGF-β1, and mTOR, which was associated with improvement of serum biochemical parameters ALT and AST. In conclusion, linagliptin might help to protect the liver against persistent injury-related consequences.

Abstract
BACKGROUND Alkaline phosphatase (ALP) has been implicated to be associated with poor outcome in ischemic stroke patients, yet its role in aneurysmal subarachnoid hemorrhage (aSAH) patients is unknown. The current study aimed to investigate the on-admission and short-term variation trend of ALP levels in aSAH patients as well as its associations with vasospasm, delayed cerebral ischemia (DCI), and outcome after aSAH. METHODS Between January 2014 and May 2018, all consecutive aSAH patients were prospectively enrolled. Blood samples from patients and 78 healthy individuals were obtained. Baseline information, clinical data, and radiologic data were collected, and serum ALP levels during hospitalization were measured. Patients were followed up for 6 months. RESULTS One hundred and ninety-six aSAH patients were included. The serum ALP levels in aSAH patients were significantly higher compared to controls (71 vs. 61 U/L, p = 0.0002), yet did not differ significantly between patients with severe (WFNS 4-5) and mild clinical condition (72 vs. 63 U/L, p = 0.3362). However, ALP was significantly higher in patients with severe radiologic status (modified Fisher 3-4) compared to those with mild radiologic status (77 vs. 61.5 U/L, p = 0.0005). A significant correlation emerged between modified Fisher score and ALP level (r = 0.246, p = 0.001). Multivariable analysis found that higher ALP level was associated with angiographic vasospasm (OR 1.019, 95% CI 1.002-1.036, p = 0.026) and DCI-caused clinical deterioration (OR 1.019, 95% CI 1.001-1.037, p = 0.037), while higher WFNS score, modified Fisher score, and ALP level were independently associated with unfavorable outcome (serum ALP level, OR 1.083, 95% CI 1.041-1.127, p < 0.001). Trend analysis of ALP level based on 103 patients' data revealed a significant decrease in ALP level on post-admission day 7-9 (median; on-admission day vs. post-admission day 7-9, 72 vs. 60 U/L, p = 0.0012; post-admission day 3-5 vs. day 7-9, 70 vs. 60 U/L, p = 0.0052) and subsequent increase in ALP level on post-admission day 12-14 (median, 84 U/L, p < 0.0001). Higher ALP levels were observed in patients with unfavorable outcome on on-admission day, post-admission day 3-5, and 12-14 (median; unfavorable vs. favorable; on-admission day, 86 vs. 67 U/L, p = 0.0122; post-admission day 3-5, 80 vs. 64 U/L, p = 0.0044; post-admission day 7-9, 75 vs. 53.5 U/L, p < 0.0001) but not on post-admission day 12-14. CONCLUSIONS Elevated serum ALP level is associated with vasospasm, DCI-caused clinical deterioration, and functional outcome after aSAH. Further studies are required to examine the potential role of serum ALP as an outcome predictor for aSAH patients.

Abstract
Background: Sodium valproate (VPA) is considered as the drug of choice for the treatment
of generalized epilepsy in children. Sodium Valproate may be
hepatotoxic. Aim: To assess the level of derangement of liver enzymes in children with epilepsy
on treatment with sodium valproate. Methods: A cohort study. One hundred fifty-three children, comprising 51 with epilepsy
on treatment with VPA (group I), 51 with epilepsy on treatment with other
antiepileptic drugs (AEDs) but not VPA (group II), and 51 with nonconvulsive
disorders (group III) had liver function tests performed for them. Data were
analyzed by SPSS version 23.0. Results: There were 85 males and 68 females, aged 6 months to 14 years (median = 7.0
years). There was no significant difference in the mean plasma levels of
alanine transaminase (ALT), alkaline phosphatase, and gamma glutamyl
transferase across the three groups of children. The mean aspartate
transaminase level was significantly higher in children in group III. There
was a statistically significant negative correlation between the duration of
AED therapy and the mean serum level of AST (r = −0.266,
P = 0.016). The serum ALT level showed a statistically
significant positive correlation with the duration of AED therapy
(r = 0.268, P = 0.015). Conclusion: Sodium valproate monotherapy does not appear to be associated with
significant hepatotoxicity in children in our cohort.

Abstract
Adenosine deaminase (ADA) is a key enzyme of adenosine metabolism. There are currently various kits and systems available for ADA measurement, and all yield variable results. This study optimized a reference measurement procedure (RMP) for serum ADA for the standardization of routine methods. ADA coupled with purine-nucleoside-phosphorylase, xanthine-oxidase and peroxidase was selected as the basic method and was optimized using Response Surface Methodology. Then the performance was validated and the results were compared after replication by 3 other reference laboratories. A reference interval was also developed. In addition, this optimized method was applied to calibrate a routine system. The intra-assay precision was 0.44% at both concentrations of 29.8 and 100.4 U/L, and inter-assay precision was 1.01% and 0.95% at 30.1 and 100.3 U/L, respectively. The linearity was up to 351.9 U/L (R2 = 0.9998), with no significant interference or carryover (<5%). A Comparison among 4 reference laboratories showed good reproducibility (R2 ≥ 0.9975). The procedure proved valid for a reference interval of 11.7-38.5 U/L. The mean relative deviation for a routine system was -55.9% and -3.7% before and after calibration. This candidate RMP for serum ADA can potentially be used for standardization of clinical systems.

Abstract
BACKGROUND C-reactive protein (CRP) is considered a marker of inflammation. We sought to evaluate the association between CRP level and commonly use blood tests in apparently healthy population. METHODS A cross-sectional study of all visits in a routine health examination center between 1/2002 and 7/2018. CRP, complete blood count and chemistry blood panel were evaluated in each visit. Visits of individuals who had CRP above the 99th percentile or use statins were excluded. Correlation between CRP and blood tests was evaluated in the whole cohort as well as in sub-populations. RESULTS Blood parameters of 33,261 visits were included. Moderate positive correlation between CRP and white blood cells count (r = 0.269), neutrophils count (r = 0.275), triglycerides (r = 0.275), alkaline phosphatase (r = 0.221) and gamma glutamyl transpeptidase (r = 0.220) was evaluated. Correlation with triglycerides was stronger in female then in males (r = 0.38 vs. 0.25). Uric acid was positively correlated in females and males. In participants under 30 years, inverse correlation with hemoglobin, creatinine and albumin levels and positive correlation with cholesterol were documented. CONCLUSION Significant moderate association between CRP and several blood tests was evaluated in apparently healthy population. This information should be used for further studies of the relationship between inflammation and biological processes.

Increased cardiovascular morbidity and mortality in chronic kidney disease (CKD) represents an emerging major health problem. Indeed, disturbances in mineral and bone metabolism occur frequently in CKD and are termed chronic kidney disease - mineral and bone disorder (CKD-MBD). These can lead to cardiovascular pathology, resulting in an increased cardiovascular risk. Bone alkaline phosphatase (BALP) is essential for biomineralization. Recent findings demonstrate a crucial role for BALP in the pathogenesis of vascular calcification and identified it as a promising predictor of mortality in CKD. In conjunction with parathyroid hormone (PTH), serum BALP has been suggested as a biomarker of bone turnover in CKD-MBD. In contrast to PTH, serum BALP demonstrates a lower variability and may thus be better suited for the diagnosis and longitudinal follow-up of bone turnover. The linear association with mortality, compared to the U-shaped curve for PTH, is an additional advantage, making BALP more suitable than PTH as a treatment target in CKD. Here we review the main characteristics of alkaline phosphatase isozymes/isoforms and the various assays currently used in clinical routine laboratories. We also discuss the role of BALP in both physiological and pathological mineralization, and the clinical benefit of BALP determination in CKD.

Jain RB. Concentration of selected liver enzymes across the stages of glomerular function: the associations with PFOA and PFOS. Heliyon 2019; 5:e02168. [PMID: 31388590 PMCID: PMC6667701 DOI: 10.1016/j.heliyon.2019.e02168] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 07/20/2019] [Accepted: 07/24/2019] [Indexed: 02/07/2023] Open
Abstract
Kidney function/dysfunction may affect liver function/dysfunction and vice versa. Liver function is indicated by the observed concentrations of several liver enzymes. Kidney function is indicated by the glomerular filtration rate. Consequently, it is logical to study associations between liver enzymes and glomerular filtration rate indicted by the stages of glomerular function (GF). Thus, this study was undertaken to evaluate the associations between selected liver enzymes and the stages of GF for US adults aged >= 20 years. Data (N = 9523) for US adults for the years 2003–2014 from National Health and Nutrition Examination Survey were analyzed to estimate variabilities in concentrations associated with liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphate (APH), and γ-glutamyl transferase (GGT) across the stages of GF and to assess variabilities in associations that perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) may have with these enzymes across the stages of GF. Those with eGFR >90 mL/min/1.73 m2 were defined as being in GF-1, those with eGFR between 60 and 89 mL/min/1.73 m2 were defined as being in GF-2, those with eGFR between 45 and 59 mL/min/1.73 m2 were defined as being in GF-3A, those with eGFR between 15 and 44 mL/min/1.73 m2 were defined as being GF-3B/4. Regression models stratified by GF stages with ALT, AST, APH, and GGT as dependent variables were fitted to evaluate the associations of interest. Adjusted levels of ALT decreased with deteriorating kidney function from 25.3 IU/L at GF-1 to 20.9 IU/L at GF-3B/4 for obese adults and from 21.4 IU/L at GF-1 to 16.4 IU/L at GF-3B/4 for nonobese adults. Adjusted levels of AST followed inverted U-shaped distributions with increases from GF-1 to GF-2 followed by decreases from GF-2 to GF-3B/4. Adjusted levels of APH followed inverted U-shaped distributions with increases from GF-1 to GF-3A followed by decreases from GF-3A to GF-3B/4. Adjusted levels of GGT followed inverted U-shaped distribution among obese participants with point of inflection located at GF-3A. For the total population, obese had higher adjusted levels than nonobese at GF-1, GF-2, and GF-3A for ALT, APH, and GGT. Male-female differences in adjusted levels of ALT and GGT continued narrowing as kidney function deteriorated from GF-1 to GF-3B/4. The differences in ALT widened among nonobese smokers and nonsmokers as kidney function deteriorated. The concentrations of liver enzymes across GF stages varied by gender, race/ethnicity, smoking status, and obesity and more often than not, were indicated by inverted U-shaped curves with points of inflections located at G-2 or GF-3A. The associations between PFOA/PFOS with liver enzymes varied in magnitude and/or direction by stages of GF as kidney function deteriorated.

Impact of coccidiostat and phytase supplementation on gut microbiota composition and phytate degradation in broiler chickens. Anim Microbiome 2019; 1:5. [PMID: 33499963 PMCID: PMC7803125 DOI: 10.1186/s42523-019-0006-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 05/27/2019] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND There is good evidence for a substantial endogenous phytase activity originating from the epithelial tissue or the microbiota resident in the digestive tract of broiler chickens. However, ionophore coccidiostats, which are frequently used as feed additives in broiler diets to prevent coccidiosis, might affect the bacterial composition and the abundance of phytase producers in the gastrointestinal tract. The aim of the present study was to investigate whether supplementation of a frequently used mixture of the coccidiostats Narasin and Nicarbazin alone or together with a phytase affects microbiota composition of the digestive tract of broiler chickens, characteristics of phytate breakdown in crop and terminal ileum, and precaecal phosphorus and crude protein digestibility. RESULTS Large differences in the microbial composition and diversity were detected between the treatments with and without coccidiostat supplementation. Disappearance of myo-inositol 1,2,3,4,5,6-hexakis(dihydrogen phosphate) (InsP6) in the digestive tract, precaecal P digestibility, inorganic P in blood serum, and the concentration of inositol phosphate isomers in the crop and ileum digesta were significantly affected by phytase supplementation, but not by coccidiostat supplementation. Crude protein digestibility was increased by coccidiostat supplementation when more phosphate was available. Neither microbial abundance and diversity nor any other trait measured at the end of the experiment was affected by coccidiostat when it was only supplemented from day 1 to 10 of age. CONCLUSIONS The coccidiostats used herein had large effects on overall microbiota composition of the digestive tract. The coccidiostats did not seem to affect endogenous or exogenous phytase activity up to the terminal ileum of broiler chickens. The effects of phytase on growth, phosphorus digestibility, and myo-inositol release were not altered by the presence of the coccidiostats. The effects of phytase and coccidiostats on nutrient digestibility can be of significant relevance for phosphorus and protein-reduced feeding concepts if confirmed in further experiments.

Abstract
N-Acetyl-p-aminophenol (APAP) or acetaminophen is the most common drug ingredient worldwide. It is found in more than 600 different over-the-counter and prescription medicines. Its long-term and overdose use is highly toxic and may result in liver injury. Thus, this study was designed to assess the preventive effects and to suggest the mechanisms of action of the navel orange peel hydroethanolic extract, naringin, and naringenin in APAP-induced hepatotoxicity in male Wistar rats. APAP was administered to male Wistar rats at a dose level of 0.5 g/kg body weight (b.w.) by oral gavage every other day for 4 weeks. APAP-administered rats were treated with the navel orange peel hydroethanolic extract (50 mg/kg b.w.), naringin (20 mg/kg b.w.), and naringenin (20 mg/kg b.w.) by oral gavage every other day during the same period of APAP administration. The treatments of APAP-administered rats with the peel extract, naringin, and naringenin produced a significant decrease in the elevated serum AST, ALT, ALP, LDH, and GGT activities as well as total bilirubin and TNF-α levels while they induced a significant increase in the lowered serum albumin and IL-4 levels. The treatments also resulted in a significant decrease in the elevated liver lipid peroxidation and enhanced the liver GSH content and SOD, GST, and GPx activities as compared with APAP-administered control; the peel extract was the most potent in improving the liver LPO, GSH content, and GPx activity. In addition, the three treatments significantly downregulated the elevated hepatic proapoptotic mediators p53, Bax, and caspase-3 and significantly upregulated the suppressed antiapoptotic protein, Bcl-2, in APAP-administered rats. In association, the treatments markedly amended the APAP-induced liver histopathological deteriorations that include hepatocyte steatosis, cytoplasmic vacuolization, hydropic degeneration, and necrosis together with mononuclear leucocytic and fibroblastic inflammatory cells' infiltration. In conclusion, the navel orange peel hydroethanolic extract, naringin, and naringenin may exert their hepatopreventive effects in APAP-administered rats via enhancement of the antioxidant defense system and suppression of inflammation and apoptosis.

Abstract
Molecularly imprinted polymers (MIPs) and aptamers, as effective mimics of antibodies, can overcome only some drawbacks of antibodies. Since they have their own advantages and disadvantages, the combination of MIPs with aptamers could be an ideal solution to produce hybrid alternatives with improved properties and desirable features. Although quite a few attempts have been made in this direction, a facile and controllable approach for the preparation of aptamer-MIP hybrids still remains lacking. Herein, we present a new approach for facile and controllable preparation of aptamer-MIP hybrids for high-specificity and high-affinity recognition toward proteins. An aptamer that can bind the glycoprotein alkaline phosphatase (ALP) with relative weak affinity and specificity was used as a ligand, and controllable oriented surface imprinting was carried out with an in-water self-polymerization system of dopamine. A thin layer of polydopamine was formed to cover the template to an appropriate thickness. After removing the template from the polymer, an aptamer-MIP hybrid with apparently improved affinity and specificity toward ALP was obtained, giving cross-reactivity of 3.2-5.6% and a dissociation constant of 1.5 nM. With this aptamer-MIP hybrid, a plasmonic immunosandwich assay (PISA) was developed. Reliable detection of ALP in human serum by the PISA was demonstrated.

Abstract
Pulmonary tuberculosis (PTB) is associated with chronic inflammation and anemia. How anemia impacts systemic inflammation in PTB patients undergoing antitubercular therapy (ATT) is not fully understood. In the present study, data on several blood biochemical parameters were retrospectively analyzed from 118 PTB patients during the first 60 days of ATT. Multidimensional statistical analyses were employed to perform detailed inflammatory profiling of patients stratified by anemia status prior to treatment. Anemia was defined as hemoglobin levels <12.5 g/dL for female and <13.5 g/dL for male individuals. The findings revealed that most of anemia cases were likely caused by chronic inflammation. A distinct biosignature related to anemia was detected, defined by increased values of uric acid, C-reactive protein, and erythrocyte sedimentation rate. Importantly, anemic patients sustained increased levels of several biochemical markers at day 60 of therapy. Preliminary analysis failed to demonstrate association between persistent inflammation during ATT with frequency of positive sputum cultures at day 60. Thus, TB patients with anemia exhibit a distinct inflammatory profile, which is only partially reverted at day 60 of ATT.

Abstract
Objective Recent studies have shown that alkaline phosphatase (ALP) might play a negative role in clinical outcomes of patients with peripheral and coronary artery disease. This study aimed to investigate the relationship between serum ALP levels and coronary thrombolysis in myocardial infarction (TIMI) frame counts in patients with ST-segment elevated myocardial infarction undergoing primary percutaneous coronary intervention (PCI). Methods A total of 198 patients were enrolled in the current study. Serum ALP levels were measured in lithium-heparin plasma samples via a standardized, colorimetric enzyme assay. Coronary TIMI flow was evaluated by counting the number of cine frames that were required for contrast to reach a standardized distal coronary landmark in the culprit vessel. Results The Spearman correlation coefficient test showed strong positive relationships between coronary TIMI frame counts after primary PCI and serum ALP levels on admittance for the left anterior descending, circumflex, and right coronary arteries (r = 0.774, r = 0.831, and r = 0.730, respectively). Conclusion Elevated serum ALP levels appear to be a predictor of impaired coronary TIMI frame count in patients suffering from ST-segment elevated myocardial infarction.

Abstract
Background and Purpose—
Alkaline phosphatase (ALP) is associated with risk of adverse cardiovascular events in patients with kidney failure. However, there is little data about effects of ALP on stroke outcomes in patients with preserved kidney function. The study aimed to explore the association between serum ALP level and clinical outcomes after stroke in patients with preserved kidney function.
Methods—
We included 16 367 stroke patients with preserved kidney function from the China National Stroke Registry for current analysis. Serum ALP levels were tested by automated enzymatic method using unfrozen samples in each center. Participants were divided into 5 groups according to ALP quintiles. Composite end point comprised of recurrent stroke, myocardial infarction, other ischemic vascular events, and all-cause mortality. Poor functional outcome is defined as modified Rankin Scale score of 3 to 6. Multivariable logistic regression was used to evaluate the independent association of serum ALP with 1-year all-cause mortality, recurrent stroke, composite end point, and poor functional outcome.
Results—
The mean age of the included 16 367 patients was 63.9 years, and 63.3% of them were men. Among the top ALP quintile (>98.0 U/L), 1-year incidences of all-cause mortality, recurrent stroke, composite end point, and poor functional outcome were 12.6%, 5.7%, 14.4%, and 27.0%, respectively. Compared with the lowest ALP quintile (≤59.0 U/L), the adjusted odds ratios of the top quintile were 1.36 (1.10–1.68) for all-cause mortality, 1.45 (1.11–1.90) for stroke recurrence, 1.35 (1.12–1.63) for composite end point, and 1.36 (1.17–1.60) for poor functional outcome. There was no significant interaction between age, sex, or alcohol consumption and ALP (
P
for interaction ≥0.10) for all outcomes.
Conclusions—
In patients with preserved kidney function, ALP may be an independent predictor of all-cause mortality, stroke recurrence, composite end point, and poor functional outcome after stroke.

Abstract
BACKGROUND AND AIMS Whether gamma-glutamyl transferase (GGT) or alkaline phosphatase (ALP) is a better prognostic marker in patients with coronary heart disease (CHD) remains unknown. The aim of this study was to compare the prognostic value of GGT and ALP in patients with CHD. METHODS AND RESULTS This study included 3768 patients with CHD. The main study outcome was 3-year all-cause mortality. The median values of GGT and ALP were 36.2 U/L and 69.3 U/L. Patients were divided into subgroups according to GGT or ALP activity > or ≤median. Overall, there were 304 deaths: 195 deaths occurred in patients with GGT >median (n = 1882) and 109 deaths occurred in patients with GGT ≤median (n = 1886); Kaplan-Meier [KM] estimates of all-cause mortality were 11.9% and 6.4% (unadjusted hazard ratio [HR] = 1.85, 95% confidence interval [CI], 1.46 to 2.34]; P < 0.001). According to ALP activity, 186 deaths occurred in patients with ALP >median (n = 1883) and 118 deaths occurred in patients with ALP ≤median (n = 1885); KM estimates of all-cause mortality were 11.4% and 7.1% (unadjusted HR = 1.64 [1.30-2.06]; P < 0.001). After adjustment, GGT (adjusted HR = 1.32 [1.11-1.58]; P = 0.002) but not ALP (adjusted HR = 1.20 [1.00-1.43]; P = 0.051, with both HR calculated per 1 unit increment in logarithmic GGT or ALP scale) remained significantly associated with the risk for mortality. The C statistic of the mortality model with GGT was greater than the C statistic of the model with ALP (0.831 [0.802-0.859] vs. 0.826 [0.793-0.855]; P < 0.001). CONCLUSIONS In patients with CHD, GGT was a stronger correlate of all-cause mortality than ALP.

Mol Med Rep 2017; 16:5225-5234. [PMID: 28849079 PMCID: PMC5647077 DOI: 10.3892/mmr.2017.7295] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2015] [Accepted: 06/13/2017] [Indexed: 02/05/2023] Open
Abstract
Betaine has previously been demonstrated to protect the liver against alcohol‑induced fat accumulation. However, the mechanism through which betaine affects alcohol‑induced hepatic lipid metabolic disorders has not been extensively studied. The present study aimed to investigate the effect of betaine on alcoholic simple fatty liver and hepatic lipid metabolism disorders. A total of 36 rats were randomly divided into control, ethanol and ethanol + betaine groups. Liver function, morphological alterations, lipid content and tumor necrosis factor (TNF)‑α levels were determined. Hepatic expression levels of diacylglycerol acyltransferase (DGAT) 1, DGAT2, sterol regulatory element binding protein (SREBP)‑1c, SREBP‑2, fatty acid synthase (FAS), 3‑hydroxy‑3‑methyl‑glutaryl (HMG)‑CoA reductase, peroxisome proliferator-activated receptor λ coactivator (PGC)‑1α, adiponectin receptor (AdipoR) 1 and AdipoR2 were quantified. Serum and adipose tissue adiponectin levels were assessed using an enzyme‑linked immunoassay. The results demonstrated that alcohol‑induced ultramicrostructural alterations in hepatocytes, including the presence of lipid droplets and swollen mitochondria, were attenuated by betaine. Hepatic triglyceride, free fatty acid, total cholesterol and cholesterol ester contents and the expression of DGAT1, DGAT2, SREBP‑1c, SREBP‑2, FAS and HMG‑CoA reductase were increased following ethanol consumption, however were maintained at control levels following betaine supplementation. Alcohol‑induced decreases in hepatic PGC‑1α mRNA levels and serum and adipose tissue adiponectin concentrations were prevented by betaine. The downregulation of hepatic AdipoR1 which resulted from alcohol exposure was partially attenuated by betaine. No significant differences in liver function, TNF‑α, phospholipid and AdipoR2 levels were observed among the control, ethanol and ethanol + betaine groups. Overall, these results indicated that betaine attenuated the alcoholic simple fatty liver by improving hepatic lipid metabolism via suppression of DGAT1, DGAT2, SREBP‑1c, FAS, SREBP‑2 and HMG‑CoA reductase and upregulation of PGC‑1α.

Abstract
Boronate affinity materials, as unique sorbents, have emerged as important media for the selective separation and molecular recognition of cis-diol-containing compounds. With the introduction of boronic acid functionality, boronate affinity materials exhibit several significant advantages, including broad-spectrum selectivity, reversible covalent binding, pH-controlled capture/release, fast association/desorption kinetics, and good compatibility with mass spectrometry. Because cis-diol-containing biomolecules, including nucleosides, saccharides, glycans, glycoproteins and so on, are the important targets in current research frontiers such as metabolomics, glycomics and proteomics, boronate affinity materials have gained rapid development and found increasing applications in the last decade. In this review, we critically survey recent advances in boronate affinity materials. We focus on fundamental considerations as well as important progress and new boronate affinity materials reported in the last decade. We particularly discuss on the effects of the structure of boronate ligands and supporting materials on the properties of boronate affinity materials, such as binding pH, affinity, selectivity, binding capacity, tolerance for interference and so on. A variety of promising applications, including affinity separation, proteomics, metabolomics, disease diagnostics and aptamer selection, are introduced with main emphasis on how boronate affinity materials can solve the issues in the applications and what merits boronate affinity materials can provide.

Serum Alkaline Phosphatase and Risk of Incident Cardiovascular Disease: Interrelationship with High Sensitivity C-Reactive Protein. PLoS One 2015; 10:e0132822.

Abstract
Background Alkaline phosphatase (ALP) has been suggested to be associated with cardiovascular disease (CVD) risk, however, important aspects of the association, such as shape and independence from established risk factors, have yet to be characterized in detail. We assessed the association of ALP with CVD risk and determined its utility for CVD risk prediction. Methods Alkaline phosphatase activity was measured at baseline in the PREVEND prospective cohort involving 6,974 participants aged 28-75 years without pre-existing CVD. Hazard ratios (95% confidence intervals [CI]) and measures of risk discrimination and reclassification were assessed. Results During a median follow-up of 10.5 years, 737 participants developed CVD. Serum ALP was correlated with several risk markers for CVD, with strongest correlations for age (r = 0.30; P < 0.001), gamma-glutamyltransferase (r = 0.26; P < 0.001), and C-reactive protein (CRP) (r = 0.25; P < 0.001). There was a non-linear “J-shaped” relationship between ALP and CVD risk. In analyses adjusted for conventional risk factors, the hazard ratio (95% CI) for CVD in a comparison of the top quintile versus bottom quintiles 1-4 of ALP values was 1.34 (1.14 to 1.56; P<0.001), which persisted after additional adjustment for potential confounders 1.33 (1.13 to 1.55; P<0.001). However, the association was somewhat attenuated after adjustment for CRP 1.24 (1.05 to 1.45; P=0.009). Addition of information on ALP to a CVD risk prediction model containing established risk factors did not improve the C-index or net reclassification. Conclusions Available evidence suggests a non-linear association between ALP activity and CVD risk, which is partly dependent on CRP. Taking account of conventional risk factors, additional information on ALP does not improve CVD risk assessment.

Elevated CpG island methylation of GCK gene predicts the risk of type 2 diabetes in Chinese males. Gene 2014; 547:329-33.

Abstract
BACKGROUND The GCK gene encodes hexokinase 4, which catalyzes the first step in most glucose metabolism pathways. The purpose of our study is to assess the contribution of GCK methylation to type 2 diabetes (T2D). METHODS AND RESULTS GCK methylation was evaluated in 48 T2D cases and 48 age- and gender-matched controls using the bisulphite pyrosequencing technology. Among the four CpG sites in the methylation assay, CpG4 and the other three CpGs (CpG1-3) were not in high correlation (r<0.5). Significantly elevated methylation levels of GCK CpG4 methylation were observed in T2D patients than in the healthy controls (P=0.004). A breakdown analysis by gender indicated that the association between CpG4 methylation and T2D was specific to males (P=0.002). It is intriguing that another significant male-specific association was also found between GCK CpG4 methylation and total cholesterol (TC) concentration (r=0.304, P=0.036). CONCLUSION Our results showed that elevated GCK CpG4 methylation might suggest a risk of T2D in Chinese males. Gender disparity in GCK CpG4 methylation might provide a clue to elaborate the pathogenesis of T2D.

Abstract
BCL11A is a critical modulator involved in hemoglobin switching. Recent studies have established an association between BCL11A gene polymorphisms and a risk of type 2 diabetes (T2D). The aim of the present study was to assess the correlation between BCL11A DNA methylation and T2D. A total of 48 T2D cases and 48 age- and gender-matched controls were recruited to evaluate BCL11A methylation using bisulfite pyrosequencing technology. Although no significant association was observed in BCL11A methylation between T2D patients and healthy controls (P=0.322), breakdown analysis by gender identified a significant association between BCL11A methylation and T2D in males (P=0.018). Notably, there was also a significant female-specific association between the mean BCL11A DNA methylation and triglyceride (TG) concentration (r=−0.34; P=0.019). The results indicated that BCL11A methylation contributed to the risk of T2D in males. In addition, BCL11A methylation may have an effect on the development of T2D by influencing TG metabolism. Thus, gender difference may provide new information to aid the understanding of T2D pathogenesis.

Abstract
BACKGROUND The International Standard ISO 18153 establish that one of the requirements to assure the metrological traceability of values for catalytic concentration of enzymes is the commutability of calibrator and control materials used in the reference measurement systems. This approach was applied to verify the commutability of several commercial stabilized materials using the recently published alkaline phosphatase IFCC primary reference procedure and two routine procedures. METHODS ALP catalytic activity was measured in 50 serum samples and 16 commercial materials, including control materials from EQAS programs, using primary reference measurement procedure and two routine measurement procedures with AMP and DEA as buffers. Calibration materials with a value assigned by reference procedure which were proved to be commutable were used to recalculate the serum values obtained by routine procedures. RESULTS All commercial materials showed a similar behaviour to the patient specimens when AMP vs IFCC procedures were compared. For DEA vs IFCC comparison only one calibration material and two quality control materials were commutable. Recalculation of serum results with a commutable common calibrator improves the agreement between methods changing the ratio AMP vs IFCC from 1.44 to 1.04 and DEA vs IFCC from 3.02 to 1.05. CONCLUSIONS The use of a common commutable calibration material allows harmonizing ALP measurements and made traceable patient results to reference procedure.
