UV SPECTROPHOTOMETRIC ESTIMATION OF SUNITINIB MALATE IN PHARMACEUTICAL DOSAGE FORM

Objective: To develop and validate simple zero (D0), first (D1) and second (D2) order derivative UV Spectrophotometric methods for the determination of Sunitinib malate in pharmaceutical dosage form.Methods: Sunitinib malate was solubilised in distilled water and the resultant solution exhibits adsorption maximum (λmax) at 431, 457 and 489 nm in D0, D1 and D2 order derivative modes respectively. The developed method was validated as per ICH guidelines [1].Results: Linearity was obtained over the concentration range of 2-12 µg/ml in all the derivative modes. Limit of detection (LOD) was found to be 0.291, 0.107, 0.327μg/ml and Limit of quantification (LOQ) was found to be 0.883, 0.324, 0.993μg/ml for D0, D1 and D2 order derivative modes respectively. The proposed method demonstrated an excellent intra-day precision and inter-day precision. Mean recovery was found within the range of 98.19-98.62% respectively, signifies the accuracy of the developed method.Conclusion: The statistical results prove that the developed method can be effectively applied for the routine analysis of Sunitinib malate in industries and other analytical laboratories.Â

Study on HELLP syndrome - maternal and perinatal outcome

Background: HELLP Syndrome is a serious obstetric complication in pregnancy characterised by haemolysis, elevated liver enzymes and low platelet count. Incidence is 0.5-0.9% of all pregnancies and in 10-20% of cases with severe preeclampsia and eclampsia. The aim of the study was to study the incidence, different clinical presentations and diagnosis of HELLP syndrome in Pre eclampsia and Eclampsia and to analyze the severity, complications, maternal and perinatal outcome.Methods: It is a 16 months period retrospective study of 102 cases of preeclampsia and eclampsia admitted in NRIMC and GH in OBGY Department with more than 28 weeks gestation. Of these, 91 cases had preeclampsia and 11 cases had eclampsia. Out of these, 15 cases developed HELLP Syndrome. The available history, clinical data, detailed laboratory investigations were studied and categorized by Mississippi classification for better analysis of complications and outcome in HELLP syndrome.Results: Of 91 cases of Preeclampsia, 12 cases (13.18%) developed HELLP syndrome and out of 11 cases of Eclampsia, 3 cases (27.27%) had HELLP Syndrome. Majority of the cases belonged to 21-25years age group and were mostly from lower Socio economic status. The present study showed 60% maternal morbidity and 6.6% maternal mortality and the perinatal morbidity and mortality was 46.6% each.Conclusions: HELLP Syndrome is a severe variant and a dreadful complication of Preeclampsia and Eclampsia, it needs early diagnosis and timely intervention in the form of termination of pregnancy to arrest further progress of pathophysiology leading to complications

Isolation and characterization of lytic bacteriophages of Salmonella Typhimurium and their therapeutic application

Salmonella Typhimurium is an important bacterial pathogen of gastroenteritis revealing multidrug resistance and has zoonotic implication. In an approach towards alternatives to antibiotics, lytic bacteriophages were isolated against Salmonella Typhimurium from sewage effluent using double agar overlay method. The isolated bacteir ohages, viz. fST1, fST2, fST3, fST4 and fST5 were characterized microbiologically and revealed host range 85–92% individually and 100% collectively within the genus. Biophysical characterization revealed that the phages were stable at 16°, 37°, 42°C and pH 4, 7 and 9 for 3h, supporting their therapeutic application. Electron microscopic examination of the fST1 showed icosahedral head (52.5nm), contractile tail (220–250nm) belonging to the family Myoviridae and order Caudovirales. Further, molecular characterization of fST1 revealed 38kb nucleic acid and digested by restriction endonucleases i.e., EcoRI, Bam HI and Hae III. The therapeutic application of the isolated phage cocktail was ascertained in Swiss albino mice models by infecting the control and treatment groups with 3×108 cfu/ml of the organism intramuscularly and orally. Following challenge the treatment group administered with 3×109 pfu/ml of phage mixture showed significant decrease in number of colony forming units of bacteria in vivo

SLOW INCREASING FUNCTIONS AND THEIR APPLICATIONS TO SOME PROBLEMS IN NUMBER THEORY

This article commences with a definition of slow increasing function and moves on to delineate a few properties of slow increasing functions. Besides, several applications in some problems of number theory using the theory of slow increasing functions are also presented to show how useful these functions prove in solving complex problems

APTAMER: A REVIEW ON IT’S IN VITRO SELECTION AND DRUG DELIVERY SYSTEM

In recent year, Aptamer has been one of the key tools in the field of advanced drug delivery systems. Aptamer are oligonucleotides or peptides that bind to a specific target molecule. In this review we summarize the major differences between the antibody and an Aptamer along with the different methodology of the In vitro selection of the Aptamer by using SELEX (Systematic evolution of ligands by exponential enrichment) technique. SELEX is a technique which has a based biosensor and some of the novel drug delivery system. The article referred in this review was referred from the above said source was in the range of 1990-2020 y. Primary contents is searched from science direct, springer nature, scopus indexed journals.

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Esthetic Posterior Restorations Utilizing the Double Inlay Technique

The Insertion of tooth colored adhesively bonded posterior restorations in proximal cavities extending beyond cementoenamel junction requires a technique sensitive procedure. Should esthetic aspect deserve more prominent consideration, the concept of double inlay technique a two-part restoration provides an alternative. This procedure incorporates the advantages of cast restoration at the critical cervico proximal cavity margins and the esthetic and stabilizing properties of the adhesively bonded restoration technique in visible areas. This article describes in detail the construction of double inlay with a case repor
