RESUMO

Aspirin (AS) is a common drug having anti-pyretic and anti-inflammatory properties which is widely used in diverse medical conditions. The intake of AS may cause adverse effects such as gastrointestinal ulcer, tinnitus and Reye's syndrome. The adverse effects of AS arise due to conversion of AS into salicylic acid (SAL). Glycine (Gly) is a simplest non essential amino acid having anti-oxidative and anti-inflammatory effects. It also reduces the risk of obesity, hypertension, and diabetes mellitus. AS with Gly is well accepted form of the drug for the treatment of rheumatic conditions in comparisons to the bare AS. In the present work using UV-Visible absorption, fluorescence and DFT/ TD-DFT techniques confirmed that in presence of Gly inhibited the conversion of AS into SAL effectively.

RESUMO

Aspirin is a commonly used nonsteroidal anti-inflammatory drug, associated with many adverse effects. The adverse effects of aspirin such as tinnitus, Reye's syndrome and gastrointestinal bleeding are caused due to conversion of aspirin into its active metabolite salicylic acid after oral intake. Glutathione is a naturally occurring antioxidant produced by the liver and nerve cells in the central nervous system. It helps to metabolize toxins, break down free radicles, and support immune function. This study aims to investigate and explore the possibility of inhibiting aspirin to salicylic acid conversion in presence of glutathione at a molecular level using spectroscopic techniques such as UV-Visible absorption, time-Resolved and time-dependent fluorescence and theoretical DFT/ TD-DFT calculations. The results of steady state fluorescence spectroscopy and time-dependent fluorescence indicated that the aspirin to salicylic acid conversion is considerably inhibited in presence of glutathione. Further, the results presented here might have significant clinical implications for individuals with variations in glutathione level.

RESUMO

BACKGROUND: Pre-eclampsia and migraine share some similar aspects of pathophysiology such as vascular function, platelet activation, and enhanced clotting. A few observational studies from different demographics showed that pregnant women with a history of migraine were at higher risk of developing pre-eclampsia. However, there is no such evidence available from the Indian context. Hence, a hospital-based case-control study was conducted among Indian women to determine the association between migraine and pre-eclampsia. METHOD: It was a single-centre case-control study in a tertiary care hospital in India. Cases were pregnant women with clinically diagnosed pre-eclampsia, and controls were normotensive pregnant women. Migraine was diagnosed with a questionnaire adapted from the "International Classification of Headache Disorders (ICHD), 3rd Edition" by the International Headache Society, (IHS). We performed logistic regression to explore the association between migraine and pre-eclampsia. RESULT: One hundred sixty-four women (82 women per group) were enrolled. The mean age among the cases (24.5 years, standard deviation of 2.4 years) was slightly higher than the mean age of the controls (23.5 years, standard deviation of 2.5 years) with a p-value of 0.006. We found that women with a history of migraine were more likely to develop pre-eclampsia (Adjusted Odds Ratio 6.17; p-value < 0.001, 95% Confidence Interval of 2.85 to 13.62). CONCLUSION: The current findings suggest a significant association between migraine and pre-eclampsia aligning with previous study findings; nevertheless, larger follow-up studies including women from different states in India are needed.

RESUMO

BACKGROUND: Breast cancer is the world's most prevalent cancer among women. Microorganisms have been the richest source of antibiotics as well as anticancer drugs. Moricin peptides have shown antibacterial properties; however, the anticancer potential and mechanistic insights into moricin peptide-induced cancer cell death have not yet been explored. METHODS: An investigation through in silico analysis, analytical methods (Reverse Phase-High Performance Liquid Chromatography (RP-HPLC), mass spectroscopy (MS), circular dichroism (CD), and in vitro studies, has been carried out to delineate the mechanism(s) of moricin-induced cancer cell death. An in-silico analysis was performed to predict the anticancer potential of moricin in cancer cells using Anti CP and ACP servers based on a support vector machine (SVM). Molecular docking was performed to predict the binding interaction between moricin and peptide-related cancer signaling pathway(s) through the HawkDOCK web server. Further, in vitro anticancer activity of moricin was performed against MDA-MB-231 cells. RESULTS: In silico observation revealed that moricin is a potential anticancer peptide, and protein-protein docking showed a strong binding interaction between moricin and signaling proteins. CD showed a predominant helical structure of moricin, and the MS result determined the observed molecular weight of moricin is 4544 Da. An in vitro study showed that moricin exposure to MDA-MB-231 cells caused dose dependent inhibition of cell viability with a high generation of reactive oxygen species (ROS). Molecular study revealed that moricin exposure caused downregulation in the expression of Notch-1, NF-ƙB and Bcl2 proteins while upregulating p53, Bax, caspase 3, and caspase 9, which results in caspase-dependent cell death in MDA-MB-231 cells. CONCLUSIONS: In conclusion, this study reveals the anticancer potential and underlying mechanism of moricin peptide-induced cell death in triple negative cancer cells, which could be used in the development of an anticancer drug.

RESUMO

PURPOSE: To compare concentration and release kinetics of osteocalcin and crestal bone loss under immediate and delayed loading conditions during osseointegration. MATERIALS AND METHODS: Forty-one patients who were indicated for rehabilitation with dental implants randomly received either implant with placement of permanent prosthesis after 3 months (delayed loading) or implant with placement of permanent prosthesis within 7 days (immediate loading). Radiographic assessment of crestal bone loss at the mesial and distal surface was done at 3, 6, and 12 months after implant placement. Peri-implant sulcular fluid was collected immediately from the buccal surface at two sites after implant insertion and also, at 7, 15, 30, and 90 days after surgery. The level of osteocalcin was evaluated using ELISA and data were compared using two sample t-test. Differences between two groups were analyzed by unpaired Student's t test. Intragroup comparison was done by repeated measures ANOVA. RESULTS: Mean crestal bone loss was lower in the immediate loading group compared to the delayed loading group at 3, 6, and 12 months (p < 0.001). Intragroup comparison revealed a statistically significant increase in osteocalcin levels in both group I (delayed loading) (F = 26712.2) and group II (immediate loading) (F = 10497.2) at the predetermined time intervals. CONCLUSIONS: Less crestal bone loss and early release of osteocalcin was found in the immediately loaded group than in the delayed loaded group. The study substantiates that immediately loaded implants show less crestal bone as well as early release of osteocalcin facilitating upregulation of bone metabolism, improving long term health of bone and prognosis of implants. Immediately loaded implants can be a better treatment protocol provided there is adequate bone and primary stability.

RESUMO

In the context of the recent pandemic, the necessity of inexpensive and easily accessible rapid-test kits is well understood and need not be stressed further. In light of this, we report a multi-nucleotide probe-based diagnosis of SARS-CoV-2 using a bioelectronics platform, comprising low-cost chemiresistive biochips, a portable electronic readout, and an Android application for data acquisition with machine-learning-based decision making. The platform performs the desired diagnosis from standard nasopharyngeal and/or oral swabs (both on extracted and non-extracted RNA samples) without amplifying the viral load. Being a reverse transcription polymerase chain reaction-free hybridization assay, the proposed approach offers inexpensive, fast (time-to-result: ≤ 30 min), and early diagnosis, as opposed to most of the existing SARS-CoV-2 diagnosis protocols recommended by the WHO. For the extracted RNA samples, the assay accounts for 87 and 95.2% test accuracies, using a heuristic approach and a machine-learning-based classification method, respectively. In case of the non-extracted RNA samples, 95.6% decision accuracy is achieved using the heuristic approach, with the machine-learning-based best-fit model producing 100% accuracy. Furthermore, the availability of the handheld readout and the Android application-based simple user interface facilitates easy accessibility and portable applications. Besides, by eliminating viral RNA extraction from samples as a pre-requisite for specific detection, the proposed approach presents itself as an ideal candidate for point-of-care SARS-CoV-2 diagnosis.

RESUMO

BACKGROUND: Globally, Pediatric Intensive Care Unit (PICU) admissions are amongst the most expensive. In low middle-income countries, out of pocket expenditure (OOP) constitutes a major portion of the total expenditure. This makes it important to gain insights into the cost of pediatric intensive care. We undertook this study to calculate the health system cost and out of pocket expenditure incurred per patient during PICU stay. METHODS: Prospective study conducted in a state of the art tertiary level PICU of a teaching and referral hospital. Bottom-up micro costing methods were used to assess the health system cost. Annual data regarding hospital resources used for PICU care was collected from January to December 2018. Data regarding OOP was collected from 299 patients admitted from July 2017 to December 2018. The latter period was divided into four intervals, each of four and a half months duration and data was collected for 1 month in each interval. Per patient and per bed day costs for treatment were estimated both from health system and patient's perspective. RESULTS: The median (inter-quartile range, IQR) length of PICU stay was 5(3-8) days. Mean ± SD Pediatric Risk of Mortality Score (PRISM III) score of the study cohort was 22.23 ± 7.3. Of the total patients, 55.9% (167) were ventilated. Mean cost per patient treated was US$ 2078(₹ 144,566). Of this, health system cost and OOP expenditure per patient were US$ 1731 (₹ 120,425) and 352 (₹ 24,535) respectively. OOP expenditure of a ventilated child was twice that of a non- ventilated child. CONCLUSIONS: The fixed cost of PICU care was 3.8 times more than variable costs. Major portion of cost was borne by the hospital. Severe illness, longer ICU stay and ventilation were associated with increased costs. This study can be used to set the reimbursement package rates under Ayushman Bharat - Pradhan Mantri Jan Arogya Yojana (AB-PMJAY). Tertiary level intensive care in a public sector teaching hospital in India is far less expensive than developed countries.

RESUMO

The fluorescent properties of nitrogen doped carbon quantum dots (NCQDs) prepared through microwave assisted green method has been used as label free fluorescent probe for selective and sensitive detection of malachite green (MG) in water. The optical responses revealed that the NCQDs are highly stable and have good fluorescent quantum yield. The NCQDs were used to detect the Malchite Green in Mili Q water. Reduction in the fluorescence response was monitored in the range 17.12-128.43 µM of MG dissolved in Mili Q water. Linear response was observed in the range, 10-80 µM. The calculated value of limit of detection is 5.16 µM and the sensitivity is (0.03536 ± 0.00001) µM-1. The future application of this work is that it can be employed to detect MG in the tap water and other natural sources of water.

RESUMO

The properties of 3-Cyano-4, 6-Dimethyl-2-Pyridone (CDPy) were analyzed to study the antioxidant behavior. The UV-Visible absorption and fluorescence properties of CDPy have been studied in two protic (water and methanol) and two aprotic (acetonitrile and dimethyl sulfoxide) solvents. Its antioxidant properties were compared with well known antioxidant ascorbic acid. This compound, CDPy was found to exhibits moderate antioxidant properties. The experimental results were reproduced by theoretical density functional methods, which helped to understand the experimental result better.

RESUMO

Nitrogen doped carbon quantum dots (NCQDs) were synthesized via hydrothermal route. The NCQDs are thermally and optically stable with high flouresence yield. For the synthesis of NCQDs, citric acid and urea was taken as carbon and nitrogen sources, respectively. The Transmission Electron Microscopy (TEM) of these quantum dots revealed nearly spherical shape and average size of 1.5 nm, which was calculated using Image J software. The quantum dots were also well-characterized using spectroscopic techniques such as FTIR, UV-Visible absorption and fluorescence. These synthesized and characterized dots were utilized for selective detection of lactose in Milli Q water. The bioprobe provide a wide linear range varying from (10.00-77.41) µM with limit of detection 11.36 µM and sensitivity equal to (0.0065 ± 0.0002) µM-1. Graphical Abstract.

RESUMO

The circadian rhythm of uric acid concentration was studied under near-normal tropical conditions in 162 healthy volunteers (103 males and 59 females; 7 to 75 year). They were mostly medical students, staff members and members of their families. They were classified into 4 age groups: A (7-20 y; N = 42), B (21-40 y; N = 60), C (41-60 y; N = 35) and D (61-75 y; N = 25). They followed a diurnal activity from about 06:00 to about 22:00 and nocturnal rest. Blood samples were collected from each subject every 6 for 24 h (4 samples). Serum uric acid was measured spectrophotometrically. Data from each subject were analyzed by cosinor rhythmometry. Effects of gender, age, diet (vegetarian vs. omnivore), and smoking status on the rhythm-adjusted mean (MESOR) and circadian amplitude were examined by multiple-analysis of variance. A marked circadian variation was found in uric acid concentration in healthy Indians of all age groups. Furthermore, both the MESOR and circadian amplitude underwent changes with advancing age. In addition to effects of gender and age, diet and smoking were also found to affect the MESOR of circulating uric acid concentration in healthy Indians residing in northern India. The present observations confirmed a definite rhythm in uric acid concentrations with significant effect of gender, age, diet, and smoking status on uric acid concentration in clinical health. Mapping the circadian rhythm of serum uric acid is needed to explore their role in different pathophysiological conditions.

RESUMO

Fresh water streams contaminated with synthetic dye-containing effluents pose a threat to aquatic and human life either by preventing aquatic photosynthesis or by entering into the food chain. Adsorptive removal of such dyes with potent biosorbents is an important technique to reduce bioaccumulation and biomagnifications of the dyes in human life. We report use of betel nut (BN) husk and banana peel (BP), two most abundant ligno-cellulosic wastes, as efficient adsorbents for the removal of the basic dye methylene blue (MB). The adsorption by BN and BP was consistently high over wide ranges of pH and temperature, suggesting their dye removal potential in diverse conditions. Physico-chemical studies, e.g. scanning electron microscopy and Fourier transform-infrared spectroscopy studies, revealed changes in surface topology and functional moieties of BN and BP post adsorption, implying dye interaction with the biomass surface. The dye adsorption in both cases followed pseudo-second-order kinetics. While adsorption of MB by BN was better fitted with the Temkin isotherm model, adsorption with BP followed both Langmuir and Freundlich isotherm models. Our studies concluded that both adsorbents efficiently remove MB from its aqueous solution with BP proved to be marginally superior to BN.

RESUMO

The present study was undertaken to evaluate antidiabetic and antioxidant activities of Cassia tora (C. tora) seeds extract against streptozotocin induced diabetes in experimental rats to scientifically validate its use against diabetes. Ethanolic extract of C. tora seeds extract and standard drug (glibenclamide) prepared in aqueous gum acacia (2 %, w/v) suspension and fed orally to streptozotocin induced male adult diabetic rats of Charles Foster strain for 15 days. Biochemical parameters in normal, diabetic control, standard (600 µg/kg bw p.o.) and treated (500 mg/kg bw p.o.) animal groups were quantified and compared. Treatment of streptozotocin induced diabetic rats with ethanolic seeds extract caused significant (p < 0.001) reduction in blood glucose (270-220 mg/dl), total cholesterol (140-104 mg/dl), triglyceride (149-99 mg/dl), phospholipids (100-74 mg/dl), free fatty acid (2.39-2.00 µmol/l), lipid peroxide (9-5.63 nmol MDA/dl) and significantly increased post heparin lipolytic activity (11-14 nmol FFA released/h/l plasma) (p < 0.001). Furthermore, the seeds extract (100-400 µg) when tested for its antioxidant activity in vitro, showed significant (p < 0.001) inhibition in the generation of super oxide anions in enzymic system a (46-37, 33, 23, 21 nmol uric acid formed/min), in enzymic system b (113-91, 77, 60, 51 nmol formazon formed/min), non-enzymic system (324-230, 211, 161, 141 nmol uric acid formed/min) and hydroxyl radicals in enzymic system (544-501, 411, 319, 291 nmol 2,3-dihydroxybenzoate formed/h) and non-enzymic system (28-21, 17, 14, 12). The results of the present study demonstrated antidiabetic, antidyslipidemic and antioxidant activities of C. tora seeds which could help in prevention of diabeticdyslipidemia and related complications.

RESUMO

The circadian rhythm of human circulating lipid components was studied under nearnormal tropical conditions in 162 healthy volunteers (103 males and 59 females; 7 to 75 years of age). They followed a diurnal activity from about 06:00 to about 22:00 and nocturnal rest. These volunteers were divided into four groups: Group A (7-20 years), Group B (21-40 years), Group C (41-60 years) and Group D (61-75 years), comprising 42, 60, 35 and 25 participants, respectively. A marked circadian rhythm was demonstrated for each studied variable in each group by population-mean cosinor analysis (almost invariably p < 0.001). Furthermore, circadian rhythm characteristics were compared among the 4 groups by parameter tests and regressed as a function of age, separately for males and females. A second-order polynomial characterized the MESOR of HDL cholesterol, phospholipids and total lipids, as well as the 24-h amplitude of total cholesterol and phospholipids. The 24-h amplitude of total lipids decreased linearly with age. The 24-h acrophase of the oldest age group (Group D) was advanced in the case of total cholesterol, HDL cholesterol, and total lipids, whereas that of phospholipids was delayed. Mapping the circadian rhythm (an important component of the broader time structure or chronome, which includes a. o., trends with age and extra-circadian components) of lipid components is needed to explore their role in the aging process in health.

RESUMO

Calpain 5 (CAPN5) is a non-classical member of the calpain family. It lacks the EF hand motif characteristic of classical calpains but retains catalytic and Ca(2+) binding domains, and it contains a unique C-terminal domain. TRA-3, an ortholog of CAPN5, has been shown to be involved in necrotic cell death in Caenorhabditis elegans. CAPN5 is expressed throughout the CNS, but its expression relative to other calpains and subcellular distribution has not been investigated previously. Based on relative mRNA levels, Capn5 is the second most highly expressed calpain in the rat CNS, with Capn2 mRNA being the most abundant. Unlike classical calpains, CAPN5 is a non-cytosolic protein localized to the nucleus and extra-nuclear locations. CAPN5 possesses two nuclear localization signals (NLS): an N-terminal monopartite NLS and a unique bipartite NLS closer to the C terminus. The C-terminal NLS contains a SUMO-interacting motif that contributes to nuclear localization, and mutation or deletion of both NLS renders CAPN5 exclusively cytosolic. Dual NLS motifs are common among transcription factors. Interestingly, CAPN5 is found in punctate domains associated with promyelocytic leukemia (PML) protein within the nucleus. PML nuclear bodies are implicated in transcriptional regulation, cell differentiation, cellular response to stress, viral defense, apoptosis, and cell senescence as well as protein sequestration, modification, and degradation. The roles of nuclear CAPN5 remain to be determined.

RESUMO

The hypolipidemic activity of Cassia tora (Chakvat, Chakunda) (Family: Caesalpiniaceae) seeds extract have been studied in two models of hyperlipidemia in rats. In an acute model, hyperlipidemia was induced by injecting a single dose of Triton WR-1339 (400 mg/kg, b.w.) intraperitonially in rats. Feeding with C. tora seed extract at the dose of 500 mg/kg, b.w. exerted significant lipid lowering effect as assessed by the reversal of plasma levels of total cholesterol, phospholipids, triglyceride and reactivation of post heparin lipolytic activity. In the chronic model, hyperlipidemia was induced by feeding with cholesterol rich-HFD in rats. The treatment with seeds extract of C. tora (500 mg/kg, b.w.) simultaneously for 15 days also caused lowering of lipid levels in plasma and liver following reactivation of plasma post heparin lipolytic activity and hepatic lipoprotein lipase activity in animals. The hypolipidemic activity of C. tora seeds was compared with a standard drug guggulipid (200 mg/kg, b.w.) in both models.

RESUMO

As per the United Nations 2013 report, India's population is expected to reach 1.2 billion by 2015. Thus, there is a need for professionals trained in demography and population studies to carry out research regarding population aspects and project population growth/trends. This study landscapes the academic courses being offered in demography and population studies in India (in regular and distance learning modes). It outlines the details of these courses with respect to available courses, fee structure, number of seats, eligibility criteria, duration, nature of the program, etc. The details of the institutes offering demography and population studies courses were collected and compiled. A systematic and predefined approach including Internet search, search in the leading newspapers and discussions with students, academicians, and faculties were used to collect information for different courses provided by institutes all over India. There are around 22 institutions currently offering certificate, diploma, Masters, Master of Philosophy (M.Phil), and doctoral courses in demography and population studies in India (through regular and distance learning modes). Based on the annual intake capacity of these academic institutions, around 1,052 qualified professionals are available to work in the field of demography and population studies in India. This work has helped us to identify and track various academic courses being offered in demography and population studies in India. However, the courses that are being offered are relatively small in number when compared with the number of demographers/population scientists required. A need was also felt to include demography at the Bachelor's degree level.

RESUMO

INTRODUCTION: Recent evidence shows that pro-inflammatory cytokines may be important in the assessment of severity and prognosis in congestive heart failure (CHF). In the present study, we examine the association of cytokines with causes, grade and prognosis of CHF patients. SUBJECTS AND METHODS: Of 127 patients with CHF, 11 were excluded and the remaining 116 patients with different aetiologies of CHF, and 250 age- and sex-matched control subjects, were evaluated in this case study. Severity of disease based on the New York Heart Association (NYHA) standards, fell within functional classes II to IV. The diagnosis of HF was based on clinical manifestations as well as on echocardiographic heart enlargement. Cytokines were measured by chemiluminescence. Causes of death were assessed based on death certificates. Multivariate logistic regression analysis was used to determine the risk factors of heart failure. RESULTS: Echocardiographic ejection fraction was 39.1 +/- 8.2% (mean +/- SD) in the study group indicating class II-IV heart failure. Laboratory data showed increase in biomarkers of oxidative stress, among HF patients compared to healthy subjects. Pro-inflammatory cytokines; IL-6 and TNF-alpha were significantly higher among HF patients compared to healthy subjects. TNF-alpha and IL-6, showed significant increase among patients with CHF due to ischaemic heart disease and cardiomyopathy compared to levels among CHF patients with valvular heart disease and hypertensive heart diseases. The levels of the cytokines were significantly higher among patients with class III and IV heart failure and those who died, compared to patients with class II heart failure. Multivariate logistic regression analysis revealed that CAD, cardiomyopathy, and IL-6 were strongly associated--and low ejection fraction and TNF-alpha--weakly associated with HF. Of 116 patients, 20 (17.2%) died during a follow-up of two years, and the deaths were mainly among NYHA class III and IV patients in whom the cause of CHF was CAD (10.9%) and cardiomyopathy (6.9%) which had greater levels of cytokines. CONCLUSIONS: The findings indicated that pro-inflammatory cytokines may be important indicators of causes, severity of CHF and prognosis among these patients.

RESUMO

BACKGROUND: Efficient classification of T-acute lymphoblastic leukemia (T-ALL) involves considering various factors, such as age, white blood cell count, and chromosomal alterations. However, studying protein markers are crucial to improving T-ALL patients' diagnosis and treatment. A study analyzing the expression of proteomes was conducted to identify promising early-stage biomarkers for T-ALL patients METHODS: Label-free liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to analyze the blood proteins of both patients and healthy individuals to identify new biomarkers for T-ALL. The findings were validated by RT-PCR, ELISA and computational analysis RESULTS: The study identified 1467 proteins in the blood, of which nine were upregulated and 35 were downregulated by more than 2-fold. T-ALL patients showed a significant increase in specific disease-related proteins, such as eleven-nineteen lysine-rich leukemia protein, triggering receptor expressed on myeloid cells 1, cisplatin resistance-associated-overexpressed protein, X-ray radiation resistance-associated protein 1, tumor necrosis factor receptor superfamily member 10D, protein S100-A8, and copine-4, by more than 3-fold CONCLUSION: The findings of this study provide a valuable protein map of leukemic cells and identify potential biomarkers for leukemic aggressiveness. However, further studies using larger T-ALL patient samples must confirm these preliminary results.
