Serum alkaline phosphatase and high sensitivity C-reactive protein in type II diabetes mellitus: a risk of cardio vascular disease in South Indian population
Background: Diabetes mellitus (DM) is a clinical syndrome characterized by abnormal metabolism of carbohydrate, protein and fat resulting in hyperglycemia due to absolute or relative deficiency of insulin ending up in vascular complications leading to retinopathy, neuropathy and nephropathy. The aim of the study was to examine the relationship between alkaline phosphatase (ALP) and high sensitive C reactive protein (hsCRP), in type 2 diabetic patients. We assessed the association of ALP and hsCRP levels with CVD complication and determined its utility for CVD risk prediction in type 2 DM subjects with good and poor glycemic control. Further, we investigated correlation between serum ALP and hsCRP level with glycemic control (FBS, PP2BS, HbA1c) in subjects.Methods: A cross sectional study consists of 390 patients out of which 100 normal healthy control (Group I) , 120 patients having type 2 DM with good control (Group II), 170 patients with type 2 DM with poor control (Group III) were selected. Serum ALP, serum hsCRP, FBS, PP2BS, HbA1c, and other biochemical investigations including serum liver enzymes and lipid profile were measured.Results: In Study I Mean serum ALP(145.17±23.91) and hsCRP (2.53±0.76) concentration in group II patients when compared to group I serum ALP(142.17±16.48) and Hscrp (1.51±0.15) shows a significance of ALP (p<0.05) and Hscrp (p<0.001).Study II Mean serum ALP(145.17±23.91) and hsCRP (2.53±0.76) concentration in group II patients when compared to group III serum ALP (147.79±28.95) and Hscrp (3.848±0.47) group shows a significance of ALP (p<0.001) and Hscrp (p<0.05). Study III Mean serum ALP (147.79±28.95) and hsCRP (3.848± 0.47) concentration in group III patients when compared to group I serum ALP (142.17±16.48) and Hscrp (1.51±0.15) shows a high significance of both ALP and Hscrp (p<0.001). Further significant positive correlation was observed between ALP and hsCRP concentration as well as with HbA1c, FBS, and PP2BS.Conclusions: Inflammation along with the poor glycemic control in diabetes play a role in diabetic macrovascular complication like CVD. All these finding are showing a link between CVD, inflammation and glycemic control in patient with type 2 diabetes mellitus
Investigation of the effect of Au2O3 dopant on elastic properties of PbO-B2O3-SeO2: Er2O3 glass ceramics by ultrasonic techniques
Various elastic coefficients of Au2O3 doped PbO-B2O3-SeO2:Er2O3 (PBSE) glass
ceramics were evaluated as functions of Au2O3 content using ultrasonic velocity
measurements. The elastic coefficients and micro-hardness showed a decreasing
tendency with the concentration of Au2O3. Such decrease is attributed to the
increasing concentration of gold metallic particles and [SeO3]2- groups that
acted as modifiers and induced imperfections in these samples. Obtained results
were observed to be consistent with the conclusions drawn from spectroscopic
studies that include X-ray photoelectron spectroscopy (XPS), infrared (IR),
photoluminescence (PL) and positron annihilation (PAL) spectroscopy studies.
Overall, these studies have revealed that even though, the presence of gold
metallic particles is preferable for achieving superior luminescence and
electrical properties, presence of such particles caused to decrease the
elastic coefficients and micro-hardness of these glass ceramics. However, when
the concentration of Au2O3 is increased beyond 0.075 mol%, we have observed a
slight increase of elastic coefficients and micro-hardness.Comment: 6 pages, 8 figure
Exploring the Natural Preservation Potential of Aqueous Guava Leaf Extracts on Pangasius Pangasius: An Experimental Study
Fish, being a significant biological indicator in water, serves as a valuable food source once harvested. However, the high protein content in fish makes it an ideal medium for microorganisms, which can lead to spoilage. In areas without access to freezers or ice, preserving fish becomes a challenge. The objective of this study is to investigate the efficacy of Psidium guajava (guava) leaves as a natural preservation method for Pangasius pangasius fish. Key parameters, including gills, eye, texture, odor, and mucilage, were used to evaluate fish quality. Leaf methanolic extract was applied at doses of 0%, 20%, 40%, 60%, and 80%. Data were collected between 1 and 3 days after storage. Results showed that fish quality declined and began to deteriorate after 2 days of storage, particularly in the control treatment (0% extract). However, the fish samples treated with doses of 60% and 80% experienced relatively good quality over the course of 2 days. Although some spoilage occurred in these samples, they remained suitable for consumption. In contrast, fish samples treated with other doses exhibited complete spoilage and were no longer consumable. In conclusion, guava leaf extracts offer a promising alternative for fish preservation
Vibrational and electronic properties of 4 '-halomethyl-2-biphenylcarbonitrile compounds
In this paper we studied the structural, vibrational and electronic properties of the 4'-bromomethyl-2-biphenylcarbonitrile (BMBP) 4'-chloromethyl-2-biphenylcarbonitrile (CMBP) and 4'-fluoromethyl-2-biphenylcarbonitrile (FMBP) compounds using experimental and theoretical methods. The FT-IR and FT-Raman spectra of BMBP in solid phase were recorded in the region 4000-400 cm(-1) and 4000 -50 cm(-1), respectively. The UV absorption spectrum of BMBP was recorded in dichloromethane and methanol solvents in the range 180-400 nm. The theoretical spectral properties of title compounds were simulated using density functional theory (DFT) and time dependent DFT methods. Scaling of the vibrational frequencies was carried out with the MOLVIB program using multiple scaling factors and assignment to each vibrational frequency was consigned on the basis of potential energy distribution (PED). The electronic spectrum of BMBP in two different solvents (methanol and dichloromethane), calculated at the CAM-B3LYP/6-31G(d,p) level compares well with the experimental data and validates the current method for predicting the absorption spectrum of CMBP and FMBP. Furthermore, the electronic, nonlinear optical and thermodynamics properties of the three compounds were discussed in detailed. (C) 2017 Elsevier B.V. All rights reserved.Peer reviewe
Serum sex hormone-binding globulin levels are reduced and inversely associated with intrahepatic lipid content and saturated fatty acid fraction in adult patients with glycogen storage disease type 1a
PURPOSE: De novo lipogenesis has been inversely associated with serum sex hormone-binding globulin (SHBG) levels. However, the directionality of this association has remained uncertain. We, therefore, studied individuals with glycogen storage disease type 1a (GSD1a), who are characterized by a genetic defect in glucose-6-phosphatase resulting in increased rates of de novo lipogenesis, to assess the downstream effect on serum SHBG levels. METHODS: A case-control study comparing serum SHBG levels in patients with GSD1a (n = 10) and controls matched for age, sex, and BMI (n = 10). Intrahepatic lipid content and saturated fatty acid fraction were quantified by proton magnetic resonance spectroscopy. RESULTS: Serum SHBG levels were statistically significantly lower in patients with GSD1a compared to the controls (p = 0.041), while intrahepatic lipid content and intrahepatic saturated fatty acid fraction-a marker of de novo lipogenesis-were significantly higher in patients with GSD1a (p = 0.001 and p = 0.019, respectively). In addition, there was a statistically significant, inverse association of intrahepatic lipid content and saturated fatty acid fraction with serum SHBG levels in patients and controls combined (β: - 0.28, 95% CI: - 0.47;- 0.09 and β: - 0.02, 95% CI: - 0.04;- 0.01, respectively). CONCLUSION: Patients with GSD1a, who are characterized by genetically determined higher rates of de novo lipogenesis, have lower serum SHBG levels than controls
Synthesis, dielectric, conductivity and magnetic studies of LiNi1/3Co1/3Mn(1/3)−xAlxO2 (x = 0.0, 0.02, 0.04 and 0.06) for cathode materials of lithium-ion batteries
Layered structure cathode materials LiNi1/3Co1/3Mn(1/3)−xAlxO2 (x = 0.0, 0.02, 0.04 and 0.06) are prepared by the sol-gel method by adding citric acid as chelating agent. The physical, electrical and magnetic properties of the synthesized materials are systematically discussed using the structural (XRD, FESEM with EDS and FT-IR), impedance (LCR) and electron spin resonance (ESR) measurements. The X-ray diffraction pattern of the synthesized samples possessed the α-NaFeO2 structure of the space group, R3¯m, with no evidence of any impurities. The peak intensity ratio I(104)/I(003) increased with Al concentration, which indicated the cation mixing between transition metal layer and lithium layer. The field effect scanning electron microscopy showed the particle size distribution in the range of 230–250 nm and EDS has been analysed for elemental mapping. The local structure is investigated by vibrational spectroscopy in FT-IR study. The impedance studies are characterized by complex impedance spectroscopy (CIS) in the frequency range from 42 Hz to 1 MHz at room temperature (30 °C). The dielectric properties are analyzed in the framework of complex dielectric permittivity and formalism of the complex electric modulus. For these samples, the ESR analysis of magnetic measurements, the degree of cation mixing, is estimated to be Ni2+(3b) = 2.75%. Keywords: Layered structure, XRD, FESEM, FT-IR, Dielectric, ES
Structural, Impedance, Dielectric and Modulus Analysis of Li 0.5-x
The perovskite lithium lanthanum titanate shows high ionic conductivity at room temperature. Doping the lithium lanthanum titanate by niobium preserves the perovskite structure, which is synthesized by ceramic technology at high temperature (1300°C). The X-ray diffraction and scanning electron microscopy results show that the samples exhibit single phase. AC impedance measurements indicate total conductivity of about S/cm for composition of x = 0.05 at room temperature. The Raman spectra and cyclic voltammetry results of the compound are also reported
