RESUMO

Demand for edible oil from crops like groundnut, mustard and soybean, is increasing and likely to increase further. In this regard, Indian mustard seeds were treated with microwaves (MW), to investigate the possibility of enhancing oil yield and nutritional content. MW pre-treatment was given to the seeds of two Indian mustard varieties i.e. PM21 (V1) and PDZ1 (V2) for 0, 2, 4 and 6 min (H0, H2, H4 and H6 min respectively). MW treatment with increasing exposure time showed a linear reduction in the glucosinolate and erucic acid content with concomitant increase in oil yield and moisture loss in both the varieties, as evident from correlation and principal component analysis. Antioxidant capacity has increased with the reduction in phytic acid content (1.82) in V2 at 6 min exposure time with respect to untreated control. Free radical scavenging activity was improved with increasing MW treatment in both the varieties. Therefore, from the obtained results, it is advisable to treat mustard seeds with MW before extraction of oil, because it gives a relatively good oil yield, with enhanced nutritional factors. Moreover, microwaving was effective in reducing glucosinolates and erucic acid also.

RESUMO

Artocarpus heterophyllus shell powder was investigated in terms of its nutritional and biological potential. A thorough examination of shell powder demonstrated its potential as a source of minerals, ß carotene and dietary fiber, which were assessed gravimetrically & spectrophotometrically. This showed 3.05 ± 0.19 g 100 g(-1) DW of alkaloids followed by saponins and tannins. Three different extracts; acetone, methanol, & mix solvent were used to evaluate phenolic & flavonoid content, antioxidant & antimicrobial activity, GC/MS screening and quantitative analysis of polyphenols. Among all, the methanol extract showed highest antioxidant activity evaluated by DPPH, FRAP & ABTS assays and was significantly correlated with phenolic and flavonoid contents. Phenolic & flavonoid content was found to be 158 ± 0.34 mg (GAE) and 10.0 ± 0.64 mg (CE) respectively. The results of antimicrobial activity showed that L. monocytogenes was more susceptible to all extracts followed by other microorganisms. Catechin, ascorbic & chlorogenic acids were identified as major polyphenols analyzed by LC-MS/MS. GC/MS analysis showed that it contains a variety of compounds with different therapeutic activities. The study revealed that A. heterophyllus shell is a good source of natural antioxidants & other bioactive compounds and can be used in cosmetics, medicines and functional food application.

RESUMO

Background: Research on climatic parameters contributing to psychiatric disorder seasonality is limited, particularly in subtropical, arid climates like Rajasthan, necessitating investigation into seasonal variations in psychiatric disorder incidence in the region. This study investigates seasonal variations in psychiatric disorder prevalence over 2 years at a Rajasthan tertiary healthcare center, aiming to uncover links with climatic factors. Aims: To investigate seasonal variations in the utilization of outpatient psychiatry services and elucidate potential determinants contributing to these temporal variations. Settings and Design: This is a hospital-based study. A retrospective chart review of all new patients who utilized psychiatry outpatient services from July 2021 to July 2023 was conducted. Methods and Material: Data were gathered from psychiatric outpatient records of adults (July 2021 to July 2023), diagnosed using ICD-10. Seasons were categorized: winter (November-January), spring (February-April), summer (May-July), and rainy (August-October). Meteorological data, temperature, and day length were obtained. Statistical analyses, including Pearson correlation and Chi-square fitness, assessed seasonal associations with psychiatric disorders. Results: A total of 29,164 patient records were observed. Depression correlated with temperature and photoperiod. Mania peaked in August, linked to day length. Schizophrenia showed seasonal variation without environmental correlation. Anxiety peaked in March with no statistical significance. Obsessive compulsive disorder cases spiked in June, moderately correlated with temperature and photoperiod. Alcohol-related disorders peaked in December, while opioid dependence remained steady. Cannabis-induced psychosis peaked in summer, strongly correlated with temperature and day length. Headaches surged in August, positively correlated with temperature and day length. Conclusions: This study reveals complex relationships between seasonality, environmental factors, and psychiatric disorders, emphasizing their importance in mental health research and practice.

RESUMO

White rust disease caused by a biotrophic oomycete Albugo candida is one of the most serious impediments in realizing the production potential of Brassica juncea. Due to the obligate nature of the pathogen, R-gene-based resistance is unstable as the newer virulent races emerge quickly. For this, a deep understanding of the molecular basis of resistance is essential for developing durable resistant varieties. In this study, we selected one susceptible cultivar, 'Pusa Jaikisan' and its single R gene based resistant NIL, 'Pusa Jaikisan WRR as the source of understanding the defense mechanism in B. juncea against A. candida. Comparative histochemical analysis at 12 dpi showed higher callose deposition in the resistant cultivar than in the susceptible which hints towards its possible role in defense mechanism. Based on the biochemical markers observation, total protein was found to have a negative correlation with the resistance. The antioxidant enzymes (POX, CAT, and SOD) and non-enzymatic ROS scavenging compounds such as polyphenols and proline showed a positive correlation with the white rust resistance. Polyphenol Oxidase (PPO) total chlorophyll and total carotenoids were also found to be more abundant in the 'Pusa Jaikisan WRR'. Based on the heat map analysis, PAL was identified to be the comparatively most induced enzyme involved in the defense mechanism. The polyphenol oxidase, total chlorophyll and total carotenoids were also found to show higher activity in the 'Pusa Jaikisan WRR'. Furthermore, to study the defense response of 'Pusa Jaikisan WRR' compared to 'Pusa Jaikisan' against A. candida infection, the gene expression analyses of salicylic acid (SA)-marker PR protein genes (PR1 and PR2) and jasmonic acid (JA)-marker PR protein genes (PR3 and PR12) were done by qRT-PCR. Based on the results, PR2 emerged as the best possible gene for defense against A. candida followed by PR1. PR3 and PR12 also showed positive correlation with the disease resistance which may be due to the JA pathway acting complementary to the SA pathway in case of B. juncea-A. candida interaction. This provides evidence for the JA-SA hormonal crosstalk to be synergistic in case of the white rust resistance.

RESUMO

Membranous glomerulopathy is one of the commonest causes of nephrotic syndrome and chronic renal insufficiency in adults. There has been documented evidence of a poorer prognosis with factors such as male gender, advanced age, increased blood pressure and persistent loss of proteins in the urine, but the overall prognosis of this condition is excellent. Herein, we present the case of a 20-year-old female patient who was diagnosed with primary membranous nephropathy. Normally, cases of primary membranous nephropathy have good outcomes with conservative management and immunosuppressants but our case had a worsening course and a delayed response even with immunosuppressive treatment. This case has been recorded due to its unusual presentation, unnatural course, and outcomes contrary to what is seen in routine clinical practice.

RESUMO

Finger millet Eleusine coracana L., commonly called Ragi, is a rich source of phytochemicals and have number of health beneficial effects. The present study evaluated the total antioxidant activity (TAA), condensed tannins (CT), micronutrient content (Fe & Zn), diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, ferric reducing antioxidant power (FRAP) and phenolic compounds in 35 finger millet genotypes. The assayed genotypes showed 0.91-0.99 mg/g CT, 23.79-56.51 mM/kg TAA, 1.76-44.47 µM/g DPPH scavenging activity, 44.14-88.09 µg/mL ABTS activity, 100-463.53 µM FRAP value, 37.04-69.13 ppm Fe and 28.94-46.77 ppm Zn. HPLC analysis showed that gallic, tannic, ferulic, caffeic and o-coumaric acid to be major polyphenols in all genotypes. Principal component analysis (PCA) revealed significantly higher CT, TAA with relatively good amount of Fe and Zn in VL Ragi 146, VL Mandua 352, VL 336, VL 373, VL 325, VL 351, GPHCPB 7, GPHCPB 3, GPHCPB 52 and VR 708 genotypes. Agglomerative hierarchical cluster analysis classified the 35 genotypes into two clusters; Cluster I had higher CT, TAA, FRAP, DPPH, ABTS, while cluster II recorded higher Fe and Zn. This study clearly demonstrated the nutraceutical properties with higher antioxidant potential of identified genotypes, which can be suitably deployed for nutritional security, particularly in developing countries.

RESUMO

Objective:To determine quantitative phytochemical, anticancer and antidiabetic effect of seven Indian tropical fruit residues. Methods:In-vitro cytotoxic activity (IC50) was evaluated against cervical cancer cells (HeLa), breast cancer cells (MCF-7), hepatocellular carcinoma cells (HepG-2) and bone sarcoma cells (MG-63) and alpha amylase inhibition assay was used for antidiabetic activity. Results: Results of phytochemical analysis revealed that all residues contained remarkable amount of alkaloid, saponin, tannin and flavonoid. Notable cancer cell growth inhibition was observed for the extract from Carissa carandas pomace and Litchi sinensis seeds with IC50 values ranged from 56.72 to 89.24 μg/mL. Alpha amylase inhibition assay was measured at six different concentrations (5, 10, 25, 50, 100 and 200 mg/mL) by using different solvent extract. Results showed that Carissa carandas possessed best activity with IC50 value as 29.66 mg/mL followed by other residues in methanol extract. Conclusions:Study suggests that these fruit residues demonstrate promising antidiabetic and anticancer activity that substantiated its ethno medicinal use and may provide new molecules for the treatment of these diseases.
