Optimization of nutrient media for glucoamylase production by Plackett-Burman design using Aspergillus niger
Background: Glucoamylase is an important enzyme produced by various bacterial and fungal species as an intracellular or extra cellular enzyme. It is used to treat gastrointestinal issues, autoimmune diseases, inflammation, psoriasis, allergies, eczema, emphysema and asthma, and thus, supplements are often included in complexes for digestive disorders and also applications in different industries.
Methods: Natural ingredients are screened for glucoamylase production by stationary culture of solid-state fermentation technique and Plackett-Burman design microorganism used Aspergillus niger. Eight nutrient medias are designed and from this glucoamylase isolated from the medium by centrifugation at 1500 rpm and assayed by spectrophotometric method.
Results: high glucoamylase levels are found in nutrient media VI with optimized physical conditions like percentage inoculum- 2%, pH- 6, incubation temperature- 400C upon incubation for 4 days.
Conclusions: High amount of glucoamylase is produced in the media VI due to the presence of high amounts of sucrose and optimum concentration of potato, peptone, wheat bran and yeast extract
Biodegradation of the Azo Dye Airedale Yellow CHD: Understanding using residuals
Textile industries are heavy users of water and also produce lots of contaminated effluents. The main contaminants are azo dyes. Hence, the effluents are to be treated before leaving in the environment. In this study, the azo dye Airedale Yellow CHD was biodegraded using two bacteria Thalassospira frigidphilosprofundus (NCIM no 5438) and Erwinia chrysanthemi Burkholder (NCIM no 5213) in shaking conical flasks. Effect of Various parameters like pH, temperature, agitation, and concentration of dye solution on its decolorization was investigated. The biodegradation was statistically worked out using MINITAB software for the ANOVA. The residual plots along with the scatter plots for the decolorization of Airedale Yellow CHD using T. frigidphilosprofundus and E. chrysanthemi Burkholder are also obtained and included in this work. The maximum percent removal of the azo dye was obtained by using T. frigidphilosprofundus (77.41%) whereas it was reported at 74.64% by using E. chrysanthemi Burkholder. The obtained results formed a good fit according to the obtained normal residual plot which can conclude that the findings of the study are accurate and satisfactory
DEVELOPMENT AND VALIDATION OF STABILITY INDICATING HPTLC METHOD FOR SIMULTANEOUS DETERMINATION OF LINAGLIPTIN AND METFORMIN
Objective: A simple, precise, and accurate stability indicating high-performance thin-layer chromatography (HPTLC) method was developed and validated for simultaneous estimation of linagliptin and metformin active pharmaceutical ingredients and fixed dose combination.Methods: Linagliptin and metformin densitograms were developed on silica gel 60 F254 HPTLC plates with acetone: methanol: chloroform: formic acid (3:1:5:1v/v) as the mobile phase. Densitometric quantification was performed at 230 nm.Results: For linagliptin and metformin RF values were found as 0.72 and 0.19, respectively. The method was validated for precision, accuracy, specificity, and robustness. The linearity curves were obtained in the concentration range of 100–600 ng per spot by area with correlation coefficients of 0.999 and 0.99 for linagliptin and metformin, respectively. Limit of detection was found to be 5.19 and 8.72 ng per spot for linagliptin and metformin, respectively; lowest possible quantity to be quantified by the proposed method was found to be 15.74 and 26.44 ng per spot for linagliptin and metformin, respectively. From stability studies, the noninterference of the linagliptin and metformin degradants with drugs demonstrated the suitability of the developed method.Conclusion: The developed method was validated and found to be selective, specific and suitable for application in pharmaceutical analysis of these drugs in bulk and fixed dose combination.Â
Predicting the Perceived Interest Of Objects in Images
This thesis presents an algorithm designed to compute the perceived interest of objects in images based on results of a psychophysical experiment. We measured likelihood functions via a psychophysical experiment in which subjects rated the perceived visual interest of over 1100 objects in 300 images. These results were then used to determine the likelihood of perceived interest given various factors such as location, contrast, color, luminance, edge-strength and blur. These likelihood functions are used as part of a Bayesian formulation in which perceived interest is inferred based on the factors. A block-based approach is also proposed which doesn't need segmentation and is fast-enough to be used in real-time applications. Our results demonstrate that our algorithm can perform well in predicting perceived interest.School of Electrical & Computer Engineerin
Management of Vatarakta (Gouty Arthritis) in Ayurveda - A Review
Vatarakta is a Vatapradhana Tridoshaja Vyadhi where Raakt is main Dushya. It is described under Vatavyadhi Chikitsa in Sushruta while Charaka has emphasised it in a separate chapter for Vatarakta after Vatavyadhi Chikitsa. It is a chronic and complex metabolic disorder of musculoskeletal system and characterised by severe pain, tenderness, inflammation and burning sensation in the affected joints. Vatarakta is an illness where in both Vata and Rakta are afflicted by distinct causative factors. The etiology, pathology and clinical features of Gouty Arthritis are quite similar to that of Vatarakta. Rapid modernization, Junk food culture, stressful life and urbanisation are the markers for prevalence of Vatarakta. Due to excruciating pain, inflammation, joint deformity and restricted joint movements with the risk of various complications like Chronic Kidney Disease and Urate Nephrolithiasis, it is necessary to have an overall review on all aspects of disease for treatment. Because of the morbidity, chronicity, incurability and complications, the management of Vatarakta is a difficult task. Hence an attempt has been made to focus on Shamana Aushadis and Shodhana procedures recommended in different authentic texts of Ayurveda. Evaluation of efficacy and framing certain guideline protocols for the budding Pharmaceutical and Clinical Researchers as a readymade reckoner are the main aim and objectives of this review
SARAS 2: A Spectral Radiometer for probing Cosmic Dawn and the Epoch of Reionization through detection of the global 21 cm signal
The global 21 cm signal from Cosmic Dawn (CD) and the Epoch of Reionization
(EoR), at redshifts , probes the nature of first sources of
radiation as well as physics of the Inter-Galactic Medium (IGM). Given that the
signal is predicted to be extremely weak, of wide fractional bandwidth, and
lies in a frequency range that is dominated by Galactic and Extragalactic
foregrounds as well as Radio Frequency Interference, detection of the signal is
a daunting task. Critical to the experiment is the manner in which the sky
signal is represented through the instrument. It is of utmost importance to
design a system whose spectral bandpass and additive spurious can be well
calibrated and any calibration residual does not mimic the signal. SARAS is an
ongoing experiment that aims to detect the global 21 cm signal. Here we present
the design philosophy of the SARAS 2 system and discuss its performance and
limitations based on laboratory and field measurements. Laboratory tests with
the antenna replaced with a variety of terminations, including a network model
for the antenna impedance, show that the gain calibration and modeling of
internal additives leave no residuals with Fourier amplitudes exceeding 2~mK,
or residual Gaussians of 25 MHz width with amplitudes exceeding 2~mK. Thus,
even accounting for reflection and radiation efficiency losses in the antenna,
the SARAS~2 system is capable of detection of complex 21-cm profiles at the
level predicted by currently favoured models for thermal baryon evolution.Comment: 44 pages, 17 figures; comments and suggestions are welcom
Attenuation of Haemodynamic Response To Laryngoscopy And Intubation With Nitroglycerin
Background: Laryngoscopy and intubation are common
procedures in anesthesia. Hemodynamic responses to
mechanical stimulation of the laryngopharynx and
tracheobronchial tree cause stimulation of sympathetic
efferent fibres leading to an increased pressor response. We
in the current study tried to evaluate the effect of nitroglycerine
in the attenuation of hemodynamic responses due to
laryngoscopy and intubation.
Methods : Based on the inclusion and exclusion criteria n=80
cases were divided into two groups Group A (n=40) control
group and group B (n=40) study group randomly by computergenerated number. A detailed history is taken and a complete
physical examination is performed and the presence of any
medical disorder and history of drug intake was ruled out. All
patients were screened by radiological, biochemical, and
histological investigations, in addition to routine pre-operative
ECG.Pre-medication, induction agent and muscle relaxant to
facilitate intubation was standardized for both groups.
Results: The parameters recorded in the control group at one
minute showed hemodynamic values were increased. The
difference of SBP with the study group was 14.75 mm Hg,
diastolic blood pressure by 5 mm Hg, mean blood pressure by
8.5 mm Hg, HR was 8 beats per minute al these values were pvalues <0.05 hence considered significant. At the end of three
minutes, the comparison shows all the parameters SBP, DBP,
MBP, HR, and RPP still increased significantly in the control
group as compared to the test group. At the end of five minutes,
all the parameters were found to still significantly higher in
the control group (<0.05) as compared to the study group
except for SBP change which was found not to be significant
between both the groups.
Conclusion: The study establishes the usefulness of intravenous
Nitroglycerine to attenuate hemodynamic to laryngoscopy and
tracheal intubation. The hemodynamic changes in the study
group were well within the limits as compared to the control
group. The study also shows that there were no incidences of
adverse effects with nitroglycerine. Therefore, nitroglycerine
must be considered for attenuation of hemodynamic responses
to laryngoscopy in cases where it is indicated
IMPACT OF ALCOHOL ON PANCREAS IN ALCOHOLIC PATIENTS
Objective: Prolonged hazardous drinking can result in progressive and irreversible damage to the pancreas gland. This occurs on the background of pancreatic inflammation, acinar atrophy and, ultimately, fibrosis and can result in significant exocrine and endocrine insufficiency. Withdrawal of alcohol at an early stage may arrest the process and, even when the condition is established, may reduce the number of inflammatory episodes and allow for better control of both exocrine and endocrine insufficiencies. This study is aimed to identify the impact of alcohol on the pancreas and to educate the patient about the importance of alcohol cessation.
Methods: A retrospective study was conducted in a multispecialty clinic in the gastroenterology department for a period of one month. 60 patients were involved in the study who were diagnosed with pancreatitis (acute or chronic). The data was obtained by directly communicating with the patients which consisted of demographics and social habits.
Results: Among 60 patients, the male was dominant (85%) than female (15%). Majority of the patients were in the age group of 41-60 y (65%) followed by patients 2140 y of age (25%) and patients above 60 y of age (10%). Epigastric pain was the most common presenting complaint in all patients (67%) followed by vomiting (33%). Majority of the patients involved are alcoholics (60%).
Conclusion: Proper attention to the health at the time of diagnosis of disease by alcohol cessation can prevent the progression of the disease and helps the patient to lead a healthy life
