Dizaj i statistička optimizacija liposfera s glipizidom pomoću metodologije odgovora površine
A 32 factorial design was employed to produce glipizide lipospheres by the emulsification phase separation technique using paraffin wax and stearic acid as retardants. The effect of critical formulation variables, namely levels of paraffin wax (X1) and proportion of stearic acid in the wax (X2) on geometric mean diameter (dg), percent encapsulation efficiency (% EE), release at the end of 12 h (rel12) and time taken for 50% of drug release (t50), were evaluated using the F-test. Mathematical models containing only the significant terms were generated for each response parameter using the multiple linear regression analysis (MLRA) and analysis of variance (ANOVA). Both formulation variables studied exerted a significant influence (p < 0.05) on the response parameters. Numerical optimization using the desirability approach was employed to develop an optimized formulation by setting constraints on the dependent and independent variables. The experimental values of dg, % EE, rel12 and t50 values for the optimized formulation were found to be 57.54 ± 1.38 µm, 86.28 ± 1.32 %, 77.23 ± 2.78 % and 5.60 ± 0.32 h, respectively, which were in close agreement with those predicted by the mathematical models. The drug release from lipospheres followed first-order kinetics and was characterized by the Higuchi diffusion model. The optimized liposphere formulation developed was found to produce sustained anti-diabetic activity following oral administration in rats.32 faktorijalni dizajn primijenjen je za pripravu liposfera s glipizidom metodom separacije pomoću emulzija koristeći parafinski vosak i starinsku kiselinu kao tvari za usporavanje. Pomoću F-testa praćen je učinak kritičnih varijabli tijekom formuliranja, tj. količina parafinskog voska (X1) i udio stearinske kiseline (X2) na srednji promjer liposfera (dg), postotak inkapsulirane ljekovite tvari (% EE), oslobađanje ljekovite tvari nakon 12 h (rel12) te vrijeme potrebno za oslobađanje 50% ljekovite tvari (t50). Pomoću multiple linearne regresijske analize (MLRA) i analize varijabli (ANOVA) za svaki su parametar načinjeni matematički modeli koji sadrže samo značajne varijable. Proučavanje varijabli na oba načina ukazalo je na njihov značajan utjecaj (p < 0,05) na parametre liposfera. Postavljanjem ograničenja na zavisne i nezavisne varijable provedena je numerička optimizacija na principu poželjnosti. Eksperimentalne vrijednosti dg, % EE, rel12 i t50 optimiziranih formulacija bile su 57,54 ± 1,38 µm, 86,28 ± 1,32%, 77,23 ± 2,78% i 5,60 ± 0,32 h. Dobivene eksperimentalne vrijednosti iznosile su vrlo slične vrijednostima predviđenim matematičkim modelima. Oslobađanje glipizida iz liposfera slijedio je kinetiku prvog reda i okarakterizirano je Higuchijevim difuzijskim modelom. Optimizirane liposfere su nakon peroralne primjene na štakorima pokazale produljeni antidijabetički učinak
Studies on the chemical synthesis and characterization of lead oxide nanoparticles with different organic capping agents
Lead oxide (PbO) nanoparticles were chemically synthesized using Lead (II) acetate as precursor. The effects of organic capping agents such as Oleic acid, Ethylene Diamine Tetra Acetic acid (EDTA) and Cetryl Tri Methyl Butoxide (CTAB) on the size and morphology of the nanoparticles were studied. Characterization techniques such as X-ray diffraction (XRD), Fourier Transform-Infrared spectroscopy (FT-IR), Photoluminescence (PL) Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive Spectroscopy (EDS) and Transmission Electron Microscopy (TEM) were used to analyse the prepared nanoparticles for their physical, structural and optical properties. The characterization studies reveal that the synthesized PbO nanoparticles had well defined crystalline structure and sizes in the range of 25 nm to 36 nm for capping agents used and 40 nm for pure PbO nanoparticles
Ghat road alignment in Palamalai Hills, Tamil Nadu, India using Ghat Tracer, GPS and GIS
1162-1171Present study was conducted while fixing alignment in the study area Palamalai hills from Mulakkadai village in the plains to Kemmampatti village on the top of the hill. In this work survey to form road from Mulakkadai to Kemmampatti was conducted using Ghat Tracer, Total Station and GPS. The elevation of the starting point of the road is 320 m and the hill top is 742 m above mean sea level (MSL). Road alignment in the hilly terrain was fixed using Ghat Tracer with a gradient of 6%. Length of the alignment in the ghat section is 6.30 km with eight hairpin bends. Total station and GPS surveys were conducted along the alignment to get the coordinates. Using the data alignment plans and longitudinal sections were prepared for the proposed road. A digital map was prepared for the study area by digitizing contours, drains, roads, forest boundaries and villages. From the elevation data a digital elevation model (DEM) was prepared using GIS software. GIS was further used for creating alignment plans with
6.00 m buffer to represent the road width. The implications of using these modern technologies in time and cost aspects were discussed in this work
Characterization Studies on the Chemically Synthesized α and β Phase PbO Nanoparticles
Abstract: The α and β phase lead oxide (PbO) nanoparticles were synthesized by the simple chemical precipitation technique. The samples were characterized using X-ray diffraction (XRD), UV-visible (UV-vis) and photoluminescence (PL) spectroscopy. XRD analysis confirmed the tetragonal structure for the α-PbO and orthorhombic form for the β-PbO nanocrystallites with an average crystallite size of 36 and 47 nm, respectively. From the UV-Vis spectra the direct band gap energies were estimated as 3.91 eV for α-PbO and 3.85 eV for β-PbO. The PL studies revealed the blue and green emissions due to excitonic recombination and synthesis originated defects. No peaks appeared corresponding to near band edge emission. The density of defects in α-PbO was lower than that of β-PbO
Original Article - Physical growth and psychomotor development of infants exposed to antiepileptic drugs in utero
Objective: To evaluates the physical growth and psychomotor development
of infants born to women with epilepsy on regular Anti Epileptic Drugs
(AEDs). Setting: Govt. Stanley Medical College and Hospital,
Tertiary care referral centre, Chennai. Design: Open prospective
cohort study with a control group. Materials and Methods: Consecutive
women with epilepsy who were on regular anticonvulsants were followed
up from their first trimester. Their babies were examined at birth and
anthropometric measurements including anterior fontanelle size were
noted. They were followed up till one year and periodically evaluated
at 1st, 6th and 12th month of age. Development testing using Griffith
scale was done at 2nd, 6th and 12th month. An equal number of control
babies were also studied using the same scale for one year at the
specified intervals. The results in both the groups were compared.
Results : 30 babies were enrolled in the case and control group. The
AEDs received by the mothers with epilepsy were Phenytoin,
Carbamazepine, and Sodium valproate. At birth and 1st month the weight,
head circumference and length of case and control babies were equal. At
6th and 12th month reduction in the above 3 parameters were noted in
the case babies ( P < 0.01). Area of anterior fontanelle (AF) was
larger in the study group particularly in those exposed to phenytoin in
utero( P < 0.001). In the case babies reduction in the sitting,
prone and erect progression of the locomotor scores was observed at 2nd
month ( P < 0.001). Prone progression alone improved by 12th month
and other two remained less than the control ( P < 0.001). No
difference was observed in reaching behaviour and personal/social
scores in both groups. Infants exposed to Phenytoin monotherapy had a
negative impact on sitting progression. Conclusion : Among infants
exposed to AEDs in utero physical growth was equal to that of control
at birth but reduced at 6th and 12th month probably due to extraneous
factors. The Locomotor scores showed reduction in all areas in 2nd, 6th
and 12th month except prone progression which alone improved by 12th
month. Phenytoin exposure in utero resulted in large AF and it had a
negative impact on sitting progression in comparison with Carbamazepine
and Sodium valproate
