Study of the obstetrics and perinatal outcome of in vitro fertilization pregnancies at tertiary care centre
Background: Assisted reproductive techniques (ART) has been a boon to the unfortunate. However, the outcomes aren’t the same to all. The study has observed the outcomes in IVF conceived patients. The pregnant women were followed-up throughout their antenatal and post-natal (7 days) period and an appropriate meta-analysis was made.Methods: This is an Observational Prospective study. It was conducted at an IVF center of tertiary hospital. With valid written informed consents 96 patients were recruited and observed for18 months. Data collected by Universal sampling method, analyzed and interpreted.Results: A total 65.6% belonged above 30 years, 67.7% were primigravida and 7.3% had history of previous ectopic pregnancy. In 23.75% multifetal pregnancy was significant and 20.63% had OS tightening done. Most common reason for opting IVF was multiple failed IUI (71.6%). More than 40% were delivered by caesarean section. 91.1% of babies cried immediately after birth and 50.4% babies required NICU admission.13.4% babies had neonatal death and 3.1% were IUFD. 58.30% pregnancies were singleton. Mean birth weight was 1.87 Kg and 72.6% children were born low birth weight. Statistical significance (p<0.001) was found in between no. of foetuses delivered and preterm delivery. 56.3% birth were preterm birth. PIH and GDM complication is most common in multiple gestations observed in 10.7% of pregnancies.Conclusions: Assisted Reproductive technologies has helped the infertile couples. Outcomes could be unfruitful in few, while others may have a complicated antenatal period. Preterm deliveries are more common in multiple gestation thus complementing the lower birth weights. Comorbidities significantly affected obstetric outcome
Synthesis and Characterization of Silica from Ragi Husk Ash (Finger Millet) by a Sol-gel Method
Silica aerogel, a mesoporous material, was prepared from ragi husk ash by sol–gel method and dried under atmospheric pressure. In this method, ragi husk ash, which is rich in silica, was extracted with sodium hydroxide solution to produce a sodium silicate solution. This solution was neutralized with acid to form a silica aerogel. The aged gel was washed carefully by de ionized water and ethanol and finally dried under atmospheric air. A temperature of 7000C was found to be optimum ashing temperature with maximum amorphous silica content. From a morphological analysis obtained by SEM and diffraction patterns (XRD), a longitudinal fibrous and amorphous structure was observed for Ragi Husk. FTIR characterization indicated the presence of silanol and siloxane groups. Thermo gravimetric was used to characterize burning behaviour and also to determine the activation energies. This economic technology, as applied to waste material, also provides many benefits to the local agro-industry. Keywords: Ragi husk Ash, Sol- gel method, Amorphous silica, Aeroge

Preparation and Characterization of Silica Material from Rice Husk Ash – An Economically Viable Method
Rice husk is a form of agricultural biomass that provides an abundant silicon source. Rice husks are widely burnt in agricultural fields in India because it is difficult to find other uses for them. Farmers burn rice hulls usually under incomplete combustion conditions to avoid accidental fires. The objective of this study was to develop a new method of amorphous silica was prepared from rice husk ash by sol - gel method. Initially received from Rice husk ash was calcined at 4000C, 5000C, 6000C and 7000C for 5 hrs to remove the volatiles in the sample and determine the amorphous structure of SiO2. Next, the thermally treated RHA was mixed with alkali solution to produce sodium silicate solution and precipitated silica was produced by the neutralization of sodium silicate solution. Rice Husks soaked in nitric acid produced the maximum amount of the sodium silicate solution and precipitated silica. Sodium oxide (Na2O) content and silica (SiO2) content in the sodium silicate solution were also determined. Extracted precipitated silica particles were characterized by Fourier transform infrared (FTIR), X-Ray diffraction and Optical microscopy techniques. The chemical composition of silica was confirmed by FTIR and SEM with EDX.. Highly pure amorphous silica was derived from rice husk ash was confirmed by XRD pattern. The morphology of the obtained materials was analyzed by SEM. At optimized conditions, a nano sized highly pure silica was produced with a high reactivity and 99.9% amorphous in form. This economic technology as applied to waste material also provides many benefits to the local agro industry. Thus this paper may be providing a low cost and simple method to prepare functional materials. Keywords: Rice husk ash, Silica gel, Minerals, Amorphous material, Agricultural bio-wast
