Prosthodontic Rehabilitation of a Patient with Velopharyngeal Insufficiency using Hollow Speech Aid Prosthesis

Rehabilitation of the missing oral and extraoral structures is one of the main aim of prosthodontics. Each patient has a different type of defect that presents with its own limitations and difficulties for successful rehabilitation. Defect of any extent resulting from surgical treatment of benign and malignant neoplasms, trauma or congenital defects causes problems in mastication, speech and esthetics. Pharyngeal obturator is a prosthesis which closes the palatal and pharyngeal defects and improving the speech and other functions. The following case report discusses about palatopharyngeal insufficiency, impression procedures, fabrication of prosthesis and improvements in speech

Septate uterus: incidental finding in multiparous woman with breech with bad obstetric history who had an emergency caesarean

The most common anomalies of reproductive tract are Mullerian duct anomalies, among which septate uterus is the commonest with highest reproductive failure rate. As there are some pitfalls in diagnosis therefore the incidence is difficult to be mentioned as many remain asymptomatic. A 20 year old G5P1L0A3 with 36+4 weeks of gestation with breech presentation in active labour came to our hospital. Patient had previous history of intrauterine death at 8 months of amenorrhea and previous abortions at 5, 5 and 4 months of amenorrhoea in the year 2011, 2013, and 2014 respectively. She underwent emergency caesarean section due to breech at 36+4 weeks in active labour with the delivery of a live late preterm female baby extracted by complete breech of weight 2.28kgs with bilateral CTEV of the baby. Intraoperative findings- of septate uterus–septum extending from fundus to external os, fundal dimpling present. Though rare but uterine anomalies should be suspected in patients with recurrent pregnancy loss, preterm birth and malpresentation

Synthesis and Characterization of Coir and Luffa Cylindrica filled with CaCo3 hybrid composites

Usage of natural fiber hybrid composites is increasing in the present days because of its eco-friendly and biodegradable nature. Coir fibers were extracted from the plant bark and Luffa Cylindrical were extracted from the vegetable fruit. Later both the fibers were treated with alkaline (5% NaoH) solution to remove the greasy nature over the surface.  In the present study, composites were fabricated by using Coir and Luffa Cylindrica along with CaCo3 natural fiber hybrid composites. Each composite is tested for tensile, flexural and impact tests as per the ASTM standards. The composite specimens were characterized using Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM) and thermo-gravimetric analysis (TGA/DTA). SEM illustrated a good bonding between matrix and fibers. TGA illustrated the amount of residue leftover in the composite. FTIR illustrated which compounds are present in the composite

Synthesis and Characterization of PLA/Luffa Cylindrica Composite Films

In recent days, natural fibers have been replaced with synthetic fibers as an alternative material for the reinforcement in the polymer composites due to their renewability and sustainability. The aim of the present work is to study the performance of using natural fiber powder in the preparation of composite films. The fiber powder used in the present study is extracted from the Luffa cylindrica plant. Fourier Transform Infrared (FTIR) spectrum is utilized for the identification of functional groups in the fabricated composite film. Scanning Electron Microscopy (SEM) analysis is carried out to observe the bonding between matrix and reinforcement in the composite films. Thermal degradation behaviour of the composite film is also studied by the Thermo-gravimetric Analysis (TGA). From the studies, it was observed that the natural fiber reinforced composite film were able to withstand higher temperatures. The fabricated composites films can be effectively used for different applications where there is a necessity of bio polymers

Obstetric outcome in pregnancy complicated by ovarian cysts

Background: Ovarian masses are diagnosed in 0.5-1% pregnancies. During pregnancy ovarian cysts can undergo: resolution of the cyst, change of ultrasound pattern, occurrence of ovarian torsion and intra-cystic haemorrhage or rupture. Ovarian masses (esp torsion) is a cause of pain abdomen during pregnancy. The choice of treatment is mainly conservative, provided the patient is asymptomatic. Dilemma in management arises when the patient is symptomatic. Optimal timing for a planned surgery is the second trimester as it is shown to have least neonatal outcome. The objective of this study was to evaluate management options for ovarian cyst in pregnancy and its effect on outcome of pregnancy.Methods: This study was conducted for 2 years from June 2014 to June 2016, at RL Jalappa Hospital, Kolar. A total of 46 pregnant women were included. The pregnancy outcome and the management used were studied. Also studied were the complications most likely to occur in pregnancies complicated by ovarian masses ovarian masses.Results: Out of 46 patients, 2 (4.3%) patients with ovarian cyst torsion underwent emergency laparotomy. 8 patients underwent surgery (6 in 2nd trimester and 2 at term) for various complications. Only one patient had miscarriage and remaining patients continued till term. Histopathological report of all the masses excised were obtained and 6 were reported to be benign serous cystadenomas,1 benign mucinous cystadenoma and 3 simple cysts.Conclusions: Optimal management for ovarian cyst is conservative in pregnancy provided patient remain asymptomatic and characteristic of cyst are consistent with benign pathology. Surgical management is to be reserved for symptomatic patient

Influence of certain environmental parameters on mass production of rotifers: A review

Larviculture of many finfishes and crustaceans in aquaculture depends mainly on the live feed and its unavailability in sufficient quantity is hampering its expansion and culture progress all around the world. The most suitable feed for marine finfish larvae is the commonly available zooplankton species such as rotifer, copepods and Artemia nauplii. Among all, the live feed that has been demonstrated more successfully as the first feed for most of the marine finfish species is rotifer. Optimum conditions are required for better growth, reproduction and increased productivity of rotifers. The major factors that influence the population size of rotifer are temperature and salinity. Hence, the impact of environmental parameters with special focus on the salinity and temperature on the increase in biomass and smaller rotifer production is of utmost importance in the present scenari

Preparation of Fluconazole β-Cyclodextrin Complex Ocuserts: In Vitro and In Vivo Evaluation

The main purpose of the present study was to develop ocuserts of Fluconazole β-CD (beta-cyclodextrin) complex and to evaluate both in vitro and in vivo. Fluconazole was made complex with β-CD, and the release rate was controlled by HPMC K4M and ethyl cellulose polymers using dibutyl Phthalate as permeability enhancer. Drug-polymer interactions were studied by Fourier transform infrared spectroscopic studies. The formulated ocuserts were tested for physicochemical parameters of in vitro release and in vivo permeation in rabbits. The optimized formulations (F-5 and F-8) were subjected to stability studies. The formulated ocuserts were found to have good physical characters, thickness, diameter, uniformity in weight, folding endurance, less moisture absorption, and controlled release of drug both in vitro and in vivo. The optimized formulations retained their characteristics even after stability studies. The study clearly showed that this technique was an effective way of formulating ocuserts for retaining the drug concentration at the intended site of action for a sufficient period of time and to elicit the desired pharmacological response

A thiazolo[5,4-: D] thiazole-bridged porphyrin organic framework as a promising nonlinear optical material

Porphyrin-based porous organic frameworks are an important group of materials gaining interest due to their structural diversity and distinct opto-electronic properties. However, these materials are seldom explored for nonlinear optical (NLO) applications. In this work, we investigate a thiazolo[5,4-d]thiazole-bridged porous, porphyrin framework (Por-TzTz-POF) with promising NLO properties. The planar TzTz moiety coupled with integrated porphyrin units enables efficient π-conjugation and charge distribution in the Por-TzTz-POF resulting in a high nonlinear absorption coefficient (β = 1100 cm GW-1) with figure of merit (FoM) σ1/σ0 = 5571, in contrast to analogous molecules and material counterparts e.g. metal-organic frameworks (MOFs; β = ∼0.3-0.5 cm GW-1), molecular porphyrins (β = ∼100-400 cm GW-1), graphene (β = 900 cm GW-1), and covalent organic frameworks (Por-COF-HH; β = 1040 cm GW-1 and FoM = 3534).

Rotifer as a live feed in finfish mariculture

Among all, the first live feed that has been demonstrated successfully as first feed for most of the marine finfish species is the rotifer. It is considered as an excellent food for newly hatched fish larvae due to its small size, slow swimming speed, high calorifc value, parthenogenetic reproduction and ability to be easily enriched with antibiotics and fatty acids. Rotifers are a group of aquatic microscopic invertebrates and are commonly called 'wheel animalcules' as their disc like . corona bears resemblance to a pair of revolving wheels due to the synchronized beating of their coronal cilia. The rotifers are well represented in freshwater plankton, but only a few species of them are found in brackish waters and fewer still in the sea
