Effect of Sub-Acute Toxicity of Bifenthrin on Antioxidant status and Hematology After its Oral Exposure in Goats

The current study was undertaken to investigate the potential oxidative stress and hematological alterations induced by sub-acute oral exposure of bifenthrin in goats, after its repeated oral administration, at the dose rate of 5 mg/kg body weight daily for 28 days. The oxidative stress parameters such as malondialdehyde, blood glutathione, superoxide dismutase, catalase, glutathione peroxidase and glutathione s-transferase were studied on days 0, 3, 7, 14, 21 and 28 of bifenthrin exposure and days 7 and 14 of post-exposure period. To explore the relationship of oxidative stress with the alterations in hematological parameters like hemoglobin, packed cell volume and total erythrocyte count were also studied, simultaneously. The bifenthrin-exposed animals showed a significant increase in malondialdehyde level, whereas, the significant decrease in the levels of antioxidant parameters was noticed. A significant decrease in hemoglobin, packed cell volume and total erythrocyte count was reported, indicating a close relationship of oxidative stress and hematological alterations. After bifenthrin withdrawal, there was an improvement in the condition, as indicated by reversal in both oxidative stress and hematological parameters to the normal range.     

Erythrocytic Oxidative Stress Indices and Haemato-biochemical Changes in Fluorotic Cattle from Industrial Fluorotic Zone of Odisha

Effect of chronic fluorosis on haemato-biochemical parameters and oxidant-antioxidant equilibrium in cattle of industrial fluorotic zones of district Angul, Odisha, India was studied. Ten fluorotic cattle of visible clinical signs of endemic area and ten healthy cattle of non-fluorotic area were selected for the present study. Plasma fluoride level along with haemato-biochemical parameters was studied. Erythrocytic oxidative stress parameters like catalase, superoxide dismutase and lipid peroxidase were examined from 10 % red blood cell hemolysate. Statistical analysis of these two groups revealed altered haemato-biochemical parameters. There is high plasma fluoride level in the fluorotic cattle as compared to the healthy ones. The blood samples of the fluorotic cattle showed significant decrease (P ≤ 0.05) in haemoglobin, total erythrocyte count, total leucocyte count and packed cell volume as compared to healthy cattle. Differential leukocyte picture showed significant decrease (P ≤ 0.05) in neutrophil count in fluorotic cattle while increase in eosinophil, monocyte and lymphocyte percentage as compared to cattle of non fluorotic zone. Fluoride affected cattle revealed significantly higher (P ≤ 0.05) levels of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen and creatinine level, whereas significant decrease (P ≤ 0.05) in plasma calcium level and increase in plasma phosphorous level was recorded in fluorotic cattle as compared to healthy ones. Marked increase (P ≤ 0.05) in lipid peroxidation whereas decrease in catalase and superoxide dismutase activities was observed in fluorotic cattle as compared to healthy ones.     

Fipronil-Induced Biochemical Alterations During Oral Subacute Toxicity in Buffalo Calves

In the present investigation, detailed oral subacute toxicity study of fipronil, a phenylpyrazole insecticide, was undertaken in male buffalo calves. In oral subacute toxicity study, fipronil was administrated to male buffalo calves at repeated oral dose of 0.5 mg kg^?1 day^?1 for 21 consecutive days. Fipronil produced varying degree of mild to moderate toxic signs in buffalo calves. Fipronil produced toxic signs of salivation, lachrymal discharge, dullness, depression, decreased body weight gain, alopecia and sunken eyes. All the fipronil-exposed animals recovered within 7 days after insecticidal treatment was stopped. Repeated oral administration of fipronil at the dose rate of 0.5 mg kg^?1 day^?1 for 21 consecutive days produced significant elevation of whole blood cholinesterase to the extent of 45.17 %. Fipronil on repeated oral administration produced significant increase in the plasma levels of lactate dehydrogenase (7.08 %), aspartate aminotransferase (43.55 %) and acid phosphatase (11.647), but no significant effect on the plasma levels of alanine aminotransferase and alkaline phosphatase in male buffalo calves. Subacute oral administration of fipronil elevated the levels of gamma-glutamyl transferase (25.53 %), total plasma proteins (20.59 %) and blood glucose (40.75 %). However, no significant alteration in the levels of blood urea nitrogen, plasma creatinine and cholesterol was seen following daily oral administration of fipronil in the buffalo calves.     

Experimental Studies on the Effect of Chlorpyriphos and Lead Acetate on Biochemical Parameters in Wistar Rats with Special Reference to Ameliorative Effect of Vitamin C

The present study was designed to evaluate the effects of chlorpyriphos, lead acetate, vitamin c alone, and in combination on various biochemical parameters in wistar rats. Rats of 150–200 g body weight were divided into eight groups of six animals each and were subjected to various daily oral treatment regimes for 98 days. Group I served as control receiving only corn oil, group II received chlorpyriphos at 5.5 mg/kg in corn oil, group III received lead acetate at 100 ppm in water, whereas animals in group IVth received a combination of chlorpyriphos at 5.5 mg/kg in corn oil and lead acetate at 100 ppm in water. Group Vth received vitamin C at 100 mg/kg in water, group VIth received a combination of chlorpyriphos at 5.5 mg/kg and vitamin C at 100 mg/kg, group VIIth received lead acetate at 100 ppm in water and vitamin C at 100 mg/kg and group VIIIth received chlorpyriphos at 5.5 mg/kg, lead acetate at 100 ppm in water and vitamin C at 100 mg/kg. Chlorpyriphos and lead acetate alone or in combination elevated the activities of plasma aminotransferases, phosphatases, creatinine and blood urea nitrogen where as decreased the total plasma protein levels both due to chlorpyriphos and lead acetate treatment alone or in combination. The results showed that alterations in the biochemical parameters induced by co-exposure to chlorpyriphos and lead were mitigated by pretreatment with vitamin C. It is recommended that further research be geared towards identifying more agents that may ameliorate such adverse effects.     

Effect of Oral Subacute Exposure of Acetamiprid on Some Biochemical Parameters in Buffalo Calves

Acetamiprid is popular for crop protection against piercing-sucking pests and is highly effective for flea control in cats and dogs. Repeated oral administration of acetamiprid at the dose rate of 1.5 mg kg^?1 day^?1 for 21 consecutive days in buffalo calves did not exhibit any significant toxic signs. It however produced significant elevation in plasma aspartate aminotransferase (14 %), alanine aminotransferase (35.98 %) and gamma glutamyl transpeptidase (30.26 %), whereas no significant effect was observed on total plasma protein, blood cholinesterase, lactate dehydrogenase, phosphatases, cholesterol, creatinine, blood urea nitrogen and blood glucose. Present investigation reveals that acetamiprid is a mild-risk insecticide in buffalo calves.     

Serial change of liver stiffness measured by acoustic radiation force impulse imaging in chronic liver disease: correlation with biochemical markers

Purpose

In patients with chronic diffuse liver diseases, liver fibrosis severity is an important element for prognosis and for selecting therapy. Acoustic radiation force impulse (ARFI) imaging techniques were recently developed to measure liver fibrosis, but their specificity is impaired by cholestasis, inflammation, or edema in acute hepatitis. Herein, our objectives were to evaluate serial changes in shear wave velocity (SWV) and to correlate these changes with biochemical activity.

Methods

This study included 108 patients who underwent ARFI because of viral hepatitis [hepatitis B (HBV) or C (HCV)] with serial follow-up after 3–6 months at our institution between August 2011 and May 2013. Based on baseline and follow-up ARFI, we divided patients with HBV and HCV into two groups: a decreasing SWV group and a non-decreasing SWV group. We evaluated serial SWV changes and correlated these changes with biochemical activity changes.

Results

The patients were divided into SWV groups as follows: decreasing SWV group (HBV, n = 23; HCV, n = 7) and non-decreasing SWV group (HBV, n = 40; HCV, n = 38). In both HBV and HVC patients, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly decreased at follow-up in the decreasing SWV group.

Conclusions

The liver stiffness value assessed by ARFI became lower over time in patients who had decreasing AST and ALT levels. According to this study, ARFI overestimates fibrosis grade in patients with high AST and ALT. Thus, assessment of liver fibrosis by ARFI elastography should include consideration of biochemical markers such as AST and ALT levels and additional follow-up using ARFI elastography.     

Haemato-biochemical Responses in Cyprinus carpio (Linnaeus, 1758) Fry Exposed to Sub-lethal Concentration of a Phenylpyrazole Insecticide, Fipronil

The present study evaluates the haemato-biochemical responses associated with fipronil exposure [(±)-5-amino-1-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)-4-trifluoromethylsulfinyl-pyrazole-3-carbonitrile] in Cyprinus carpio fry. Fish were exposed to sublethal concentration (1/3rd of LC₅₀) (0.142 mg L^?1) for 15 days and corresponding changes in different haemato-biochemical parameters were recorded at the end of experimental period. Significant (P < 0.05) increase in white blood cell counts, blood glucose, serum complement reactive protein and serum cortisol level were noticed, whereas haemoglobin and serum total protein contents were significantly (P < 0.05) decreased. Aspartate amino transferase, catalase and super oxide dismutase activities were significantly (P < 0.05) increased while alkaline phosphatase and malate dehydrogenase activities were significantly (P < 0.05) decreased. Similarly, 47 % inhibition in acetylcholine esterase activity was noticed due to fipronil stress. Results indicated that sublethal exposure of fipronil can induce haemato-biochemical alterations causing stress to C. carpio fry. Thus, haemato-biochemical parameters can be used as biomarkers for the sublethal toxicity of fipronil in the water bodies.     

Down-Regulation of Acid and Alkaline Phosphatases Induced After Prolonged Diclofenac Use in Experimental Mouse Bone

The present investigation was undertaken to study the effect of diclofenac sodium on alkaline phosphatase and acid phosphatase activity in mice tibiae. Diclofenac was administered at the dose rate of 10 mg/kg body wt/day intramuscularly to experimental animals for 10, 20 and 30 days while the control group received normal saline. Alkaline phosphatase and acid phosphatase enzymes were assayed biochemically. Acid phosphatase activity was studied by histochemical analysis whereas alkaline phosphatase was analyzed by native PAGE. Student’s t test and 2-way Anova were applied wherever required. Significant decrease in acid phosphatase was revealed during this course of study which was recorded as 23.03, 22.06 and 15.72 % after 10, 20 and 30 days respectively. Similar trend of decreased acid phosphatase was demonstrated during histochemical study along with remarkable histopathological changes after diclofenac treatment for various durations of investigation. A down-regulation of 28.94 % was recorded in alkaline phosphatase activity of tibia after 10 days whereas no significant change was observed after 20 days. Slight increase (5.12 %) in alkaline phosphatase activity was documented after 30 days of drug therapy. Results from biochemical analysis of alkaline phosphatase were further supported by electrophoretic studies.     

Effects of barbiturate administration on hepatic and renal biochemical parameters in new zealand white rabbits.

To assess the initial response of various plasma hepatic and renal biochemical parameters to barbiturates, we assigned 30 new Zealand White rabbits to three treatment groups (n = 10 each): control (saline solution injected intravenously), pentobarbitone (30 mg/kg intravenously), and thiopentone (20 mg/kg intravenously). Blood samples were obtained from the central ear artery at six time points: before injection injection of the anesthetics or saline and at 10, 30, 60, and 120 min and 24 h afterward. Plasma alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma glutamiltransferase, blood urea nitrogen, and creatinine levels were measured using an autoanalyzer, and those of the treatment groups were compared with control group levels. The administration of thiopentone significantly increased plasma levels of alanine aminotransferase, aspartate aminotransferase, gamma glutamiltransferase and blood urea nitrogen, but that of plasma alkaline phosphatase significantly decreased. Plasma alkaline phosphatase and gamma glutamiltransferase levels significantly increased after pentobarbitone administration. From these results, we concluded that plasma levels of some hepatic and renal enzyme concentrations increase significantly within a short time after administration of thiopentone or pentobarbitone. Therefore, caution is required in interpreting data on plasma biochemical parameters from rabbits anesthetized with pentobarbitone or thiopentone.     

Effect of β-Glucan on Drain Fluid and Amount of Drainage Following Modified Radical Mastectomy

Introduction

To reduce the seroma formation following mastectomy and axillary dissection, many different techniques and drugs have been investigated. The aim of this study is to evaluate the effects of oral β-glucan on drain fluid and efficacy of daily drainage and drain removal day in mastectomy patients.

Methods

One hundred and thirty breast cancer patients of Ankara Oncology Training and Research Hospital were divided into 2 groups by consecutive randomization (n = 65 each). β-glucan 10 mg capsules were administered to Group 1 twice a day for 10 days. Group 2 took placebos in the same manner. Age, menarche age, menopause, parity, history of oral contraceptives, comorbidities, postoperative daily drainage volumes and drain removal days were recorded and compared. Seroma samples during the first and second day of drainage were taken for analysis of Interleukin-6 (IL-6) and Tumor Necrosis Factor (TNF-α).

Results

There was no difference between groups in terms of age, menarche age, menopause period, parity, oral contraceptive use and comorbidities. Group 1 showed significantly lower daily drainage volumes between days 2 and 8. Mean drain removal day was 7.16 ± 1.72 in Group 1 and 8.59 ± 2.27 in Group 2. The difference was significant (p < 0.001). TNF-α and IL-6 levels on days 1 and 2 in Group 1 were significantly lower (p < 0.001). In addition, β-glucan significantly shortened the number of days required for the drain removal in patients who have comorbidities (p = 0.018). The earliest removal was in patients without comorbidity and who received β-glucan (p = 0.002).

Conclusion

β-glucan decreased drain discharges after mastectomy. The drains were removed earlier in β-glucan administered patients.     

Feasibility of low-concentration iodinated contrast medium with lower-tube-voltage dual-source CT aortography using iterative reconstruction: comparison with automatic exposure control CT aortography

To evaluate the feasibility of low-concentration contrast medium (CM) for vascular enhancement, image quality, and radiation dose on computed tomography aortography (CTA) using a combined low-tube-voltage and iterative reconstruction (IR) technique. Ninety subjects underwent dual-source CT (DSCT) operating in dual-source, high-pitch mode. DSCT scans were performed using both high-concentration CM (Group A, n = 50; Iomeprol 400) and low-concentration CM (Group B, n = 40; Iodixanol 270). Group A was scanned using a reference tube potential of 120 kVp and 120 reference mAs under automatic exposure control with IR. Group B was scanned using low-tube-voltage (80 or 100 kVp if body mass index ≥25 kg/m²) at a fixed current of 150 mAs, along with IR. Images of the two groups were compared regarding attenuation, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), iodine load, and radiation dose in various locations of the CTA. In comparison between Group A and Group B, the average mean attenuation (454.73 ± 86.66 vs. 515.96 ± 101.55 HU), SNR (25.28 ± 4.34 vs. 31.29 ± 4.58), and CNR (21.83 ± 4.20 vs. 27.55 ± 4.81) on CTA in Group B showed significantly greater values and significantly lower image noise values (18.76 ± 2.19 vs. 17.48 ± 3.34) than those in Group A (all Ps < 0.05). Homogeneous contrast enhancement from the ascending thoracic aorta to the infrarenal abdominal aorta was significantly superior in Group B (P < 0.05). Low-concentration CM and a low-tube-voltage combination technique using IR is a feasible method, showing sufficient contrast enhancement and image quality.     

Influence of microvascular dysfunction on regional myocardial deformation post-acute myocardial infarction: insights from a novel angiographic index for assessing myocardial tissue-level reperfusion

To investigate the impact of microvascular dysfunction assessed by angiography on myocardial deformation assessed by two-dimensional speckle-tracking echocardiography in ST-segment elevation myocardial infarction (STEMI). A total of 121 STEMI patients who received primary percutaneous coronary intervention were included. Thrombolysis in myocardial infarction, Myocardial Perfusion Frame Count (TMPFC), a novel angiographic method to assess myocardial perfusion, was used to evaluate microvascular dysfunction. Two-dimensional speckle-tracking echocardiography was performed at 3–7 days after reperfusion. The infarction related regional longitudinal (RLS) strains as well as circumferential (RCS) and radial (RRS) ones, along with global longitudinal, circumferential (GCS), and radial (GRS) strains were measured. Patients with microvascular dysfunction had decreased peak amplitude of RLS (p = 0.012), RCS (p < 0.001), RRS (p = 0.012) at the regional level and decreased peak amplitude of GCS (p = 0.005), GRS (p = 0.012) at the global level. The RCS to RLS and RCS to RRS ratios were significantly different between patients without than with microvascular dysfunction (1.28 ± 0.31 vs. 1.07 ± 0.47, p = 0.027 and 0.69 ± 0.33 vs. 0.56 ± 0.28, p = 0.047). Receiver operator characteristics curves identified a cutoff value of 94 frames for TMPFC to differentiate between normal and abnormal wall motion score index in the sub-acute phase of STEMI (AUC = 0.72; p < 0.001). In the sub-acute phase of STEMI, the presence of microvascular dysfunction in infarcted tissue relates to reduced global and regional myocardial deformation. RCS alterations were more significant than RLS and RRS between patients with than without microvascular dysfunction. TMPFC was useful to predict left ventricular systolic dysfunction in the sub-acute phase of STEMI.     

Comparative analysis of enzyme activity in human colostrum, milk, and serum

Changes of enzyme activity in the colostrum, milk, and serum samples of 14 mothers were followed. For the enzyme assay, the colostrum and the milk samples were diluted, 1:10 and 1:5, respectively. The activity of the following enzymes were measured: lactate dehydrogenase (LDH); gammaglutamyl transpeptidase (GGT); aspartate aminotransferase (ASAT); alanine aminotransferase (ALAT); cholinesterase; alkaline, and acid phosphatase. Milk, LDH, ASAT, and ALAT activities did not change during the first four days of lactation, yet were significantly higher than the corresponding activities of serum. The activity of GGT and alkaline and acid phosphatase in milk showed a marked decrease by day 4 postpartum; however, the GGT stayed much higher than that of serum, while the activity of the other two enzymes decreased to the level of the serum. By contrast, as compared to the colostrum, the cholinesterase activity in the breast milk showed a significant increase.     

Cholinesterase activities and biochemical determinations in patients with prostate cancer: Influence of Gleason score,treatment and bone metastasis

Prostate cancer (PCa) is the sixth most common type of cancer worldwide. Cholinesterase is well known as having non-cholinergic functions such as cellular proliferation and differentiation, suggesting a possible influence of cholinesterase in tumorogenesis. Thus, the aim of this study was to investigate the whole blood acetylcholinesterase (AChE) and plasma butyrylcholinesterase (BChE) activities and some biochemical parameters in PCa patients. This study was performed in 66 PCa patients and 40 control subjects. AChE and BChE activities were determined in PCa patients and the influence of the Gleason score; bone metastasis and treatment in the enzyme activities were also verified. Furthermore, we also analyzed possible biochemical alterations in these patients. AChE and BChE activities decreased in PCa patients in relation to the control group and various biochemical changes were observed in these patients. Moreover, Gleason score, metastasis and treatment influenced cholinesterase activities and biochemical determinations. Our results suggest that cholinesterases activities and biochemical parameters are altered in PCa. These facts support the idea that the drop in the cholinesterase activity and the consequent increased amount of acetylcholine could lead to a cholinergic overstimulation and increase the cell proliferation in PCa.     

Biochemical changes in liver, kidney and blood associated with common bile duct ligation

Common bile duct ligation (CBDL) in rats was used to induce liver disease and secondary kidney damage. The biochemical changes in the liver, kidney and plasma were studied at 3, 6, 10 and 21 days post CBDL. The observed alterations climaxed at the 6th day following ligation. Renal, activities of aldolase (ALD), lactic dehydrogenase (LDH), isocitric dehydrogenase (ICDH), sorbitol dehydrogenase (SDH), and alkaline phosphatase (ALP), were lowered in CBDL rats. Further, microsomal Na,K-ATPase and Mg-ATPase and mitochondrial oxidative-phosphorylation were inhibited. In the liver from CBDL rats the activities of aspartate aminotransferase (AST), Mg-ATPase and ALP were elevated, while SDH, ALD, malic dehydrogenase (MDH), LDH, malic enzyme (ME) and Na,K-ATPase were lowered. Plasma enzymes, AST, ALP, MDH, LDH, ALD, acid phosphatase (ACP) and ICDH and the metabolites bile acids, bilirubin, creatinine and urea were elevated. Addition of bile acids or bilirubin at concentrations comparable to those found in the plasma of CBDL rats, to the reaction mixture of the various enzymes strongly inhibited most, particularly mitochondrial oxidative phosphorylation. High concentrations of these substances in the blood may explain the development of renal failure during liver disease and its reversibility when liver function returns to normal.     

Extracellular volume fraction in dilated cardiomyopathy patients without obvious late gadolinium enhancement: comparison with healthy control subjects

To evaluate whether the extracellular volume fraction (ECV) measured using cardiac magnetic resonance (CMR) imaging can detect myocardial tissue changes in dilated cardiomyopathy (DCM) without late gadolinium enhancement (LGE). Forty-one DCM patients and 10 healthy volunteers underwent pre- and post-T1 mapping using a modified Look-Locker Inversion recovery sequence, LGE, and cine MRI on a 3-T CMR system. LGE-MR findings were used to divide DCM patients into two groups: Group A had no apparent LGE, and Group B had LGE apparent in at least one segment. The ECV of the left ventricle (LV) myocardium (16 segments) was calculated in the short-axis view as follows: ECV = [(ΔR1 of myocardium/ΔR1 of LV blood pool)] × (1 ? hematocrit), where R1 = 1/T1, ΔR1 = post-contrast R1 ? pre-contrast R1. The LV ejection fraction (LVEF) was obtained from cine MRI images. The mean myocardial ECV in LGE (?) segments in Group A + B was compared to that of controls. The mean myocardial ECV in Group A was compared to that of LGE (?) segments in Group B. The correlation between LV systolic function and the mean myocardial ECV of the whole myocardium was evaluated in all groups. Among the 41 DCM patients, 22 were in Group A, and 19 were in Group B. The mean ECV of DCM patents (n = 41, 568 segments, 30.7 % ± 5.9) was significantly higher (P < 0.001) than that of the control group (n = 10, 157 segments, 25.6 % ± 3.2). The ECV was inversely related to LVEF in Group A (r = ?0.551, P = 0.008), Group B (r = ?0.525, P = 0.021), and Group A + B (r = ?0.550, P < 0.001). The ECV measured by MRI could be a useful parameter in evaluating diffuse myocardial changes in DCM patients.     

The effect of preoperative consumption of potatoes on succinylcholine-induced block and recovery from anesthesia

Potatoes contain solanaceous glycoalkaloids (SGAs), which inhibit both butyrylcholinesterase (BuChE) and acetylcholinesterase (AChE). The present study investigated the effect of preoperative consumption of potatoes on succinylcholine-induced block and recovery from anesthesia. ASA I–II, adult patients, scheduled for elective surgery, were included in a randomized, blind and controlled study. Patients were randomly divided into two groups. Patients in Group P (n = 21) ate a standard portion of potatoes in their last meal prior to pre-operative fasting, while patients in Group C (n = 23) ate food not containing SGAs. Patients were premedicated with midazolam. Anesthesia was induced with thiopental and fentanyl, and maintained with sevoflurane in 50 % O₂/air and fentanyl, as needed. Succinylcholine 1 mg kg^?1 was administered to facilitate endotracheal intubation. Duration of succinylcholine blockade, awakening and recovery times from anesthesia were measured. Serum BuChE levels were also measured at baseline and 4 time-points within 24 h post-consumption. Duration of succinylcholine-induced neuromuscular block, awakening and recovery time from anesthesia was significantly longer in Group P than in Group C (p < 0.05). Serum BuChE levels decreased at 6 h after consumption start in Group P. In addition, in both groups, BuChE levels markedly decreased after succinylcholine blockade, increased thereafter, but did not return to baseline within 24 h of consumption start. None of these differences observed in BuChE levels was statistically significant. This study suggests that potatoes eaten before anesthesia can prolong the duration of succinylcholine-induced neuromuscular block and delay recovery from anesthesia.     

Not left ventricular lead position,but the extent of immediate asynchrony reduction predicts long-term response to cardiac resynchronization therapy

Cardiac resynchronization therapy (CRT) is an effective treatment for a large subgroup of chronic heart failure patients. Various attempts to improve the high non-responder rate of 30 % by preoperative asynchrony assessment have failed. We hypothesized that superior response to CRT is correlated with greater acute reduction of asynchrony and that a concordant left ventricular (LV) lead is beneficial compared to a discordant lead. Hundred and eight consecutive CRT patients from our center were prospectively included. Clinical status and asynchrony parameters were assessed before, 1 day and 6 months after CRT implantation. Super-response was defined as an increase of the LV ejection fraction by ≥15 % and a decrease in LV end systolic volume (LVESV) by ≥30 %. When the criteria for super-response were not met, average response was given with a decrease of baseline LVESV ≥15 %. Sixty eight patients were classified as responders (63 %). Comparing super- (n = 19) and average (n = 49) responders, we found that greater acute reduction of LV asynchrony (change of asynchronous segments under CRT: ?1.3 vs. ?0.4, p < 0.05; decrease of LV intraventricular delay: ?34 ms vs. ?16 ms, p < 0.05) is associated with superior reverse remodeling after 6 months. Importantly, asynchrony parameters of super-, average and non-responders were almost identical at baseline. A concordant LV lead (n = 63) was not associated with improved LV reverse remodeling compared to a discordant lead (n = 28): LVEF: +8.6 % vs. +7.8 %, p = 0.91; LVESV: ?30.5 ml vs. ?23.8 mL, p = 0.84. A greater immediate reduction of LV asynchrony predicts superior response. Preoperative asynchrony parameters do not correlate with outcome. A concordant LV lead is not superior to a discordant lead.     

Relationship of Eating Patterns and Metabolic Parameters,and Teneligliptin Treatment: Interim Results from Post-marketing Surveillance in Japanese Type 2 Diabetes Patients

Introduction

Healthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications. We also examined whether eating patterns affected safety and efficacy of teneligliptin.

Methods

We analyzed baseline data from survey forms collected in RUBY between May 2013 and June 2017, including patient characteristics, metabolic parameters, and eating patterns (eating three meals per day or not; timing of evening meal) before teneligliptin treatment was initiated. Safety and efficacy of 12 months’ teneligliptin (20–40 mg/day) treatment was assessed.

Results

Data from 10,532 patients were available for analysis. Most patients who did not eat three meals per day (n??=757) or who ate their evening meal after 10 PM (n??=206) were 64 years old or younger. At baseline, glycated hemoglobin (HbA1c), fasting blood glucose, triglycerides, total and low-density lipoprotein cholesterol, body mass index, alanine aminotransferase, and aspartate aminotransferase levels were higher in those patients who did not eat three meals per day (p?<?0.05) or who ate their evening meal late (p?<?0.05). Diabetic complications were more common in patients who did not eat three meals per day. Treatment with teneligliptin reduced HbA1c over 6 or 12 months across all eating patterns, with a low incidence of adverse drug reactions.

Conclusions

Eating patterns may be associated with altered metabolic parameters and diabetic complications among Japanese patients with T2DM. Teneligliptin may be well tolerated and improve hyperglycemia in patients with T2DM irrespective of eating patterns.

Protective Mechanisms of Quercetin on Cisplatin Induced Oxidative Damage in Hepatic Tissue of Wistar Rats

The present study was undertaken to investigate the cisplatin (cDDP) induced oxidative damage in hepatic tissue of wistar rats and mechanisms of protection by quercetin. A total of 24 wistar rats were randomly divided into four groups with six animals in each. Group I served as control, group II received cDDP (12 mg kg^?1 body weight) and group III quercetin (50 mg kg^?1 body weight) intra-peritoneally. Group IV received quercetin 6 h prior to cDDP administration intra-peritoneally. Administration of cDDP in rats resulted in significant (P < 0.05) elevation of plasma hepatic biomarkers, reduction of antioxidant system and marked histopathological alterations indicating acute hepatotoxicity. Treatment with quercetin prior to cDDP administration prevented hepatic dysfunctions as indicated by alterations in hepatic biomarkers, alleviated enzymatic and non-enzymatic components of the antioxidant system with reduced histopathological changes in hepatic tissue. The results suggest that cDDP induced hepatic damage is due to imbalance in oxidant and antioxidant system of hepatic tissue. The pretreatment with quercetin attenuated the oxidative damage induced by cDDP in hepatic tissue and this hepatoprotective effect of quercetin may be due to its direct scavenging of free radicals and/or enhancing antioxidant defense system of hepatic tissue in wistar rats.
