Carpet industry irrigational sources risk assessment: Heavy metal contaminated vegetables and cereal crops in northern India.

Wastewater is often discharged to natural water bodies through an open channel as well as used by marginal farmers to irrigate the agricultural fields, particularly in sub-urban areas of developing countries. In the present study, the samples of irrigation water, soil, vegetables (i.e., palak; Beta vulgaris L. var All green H1, radish; Raphanus sativus L., garlic; Allium sativum L., cabbage; Brassica oleracea L. var. capitata, brinjal; Solanum melongena L.) and crops (i.e., paddy; Oryza sativa L. and wheat; Triticum aestivum L.) were collected from the agricultural areas receiving untreated wastewater from a carpet industrial and residential areas since a decade. The contents of Cd, Cr, Cu, Ni, and Zn in the filtrates of water, soil, and crops were determined using an Atomic Absorption Spectrophotometer (Perkin-Elmer AAnalyst 800, USA). Daily intake, hazardous quotient and heavy metal pollution index were computed to assess the health risk associated with consumption of heavy metal contaminated crops. The mean concentrations of Cd and Zn in B. vulgaris (5.35 µg g-1 dw and 58.41 µg g-1 dw, respectively) and Cr, Cu, and Ni in grains of T. aestivum (16.02 µg g-1 dw, 27.97 µg g-1 dw and 40.74 µg g-1 dw, respectively) were found highest and had exceeded the Indian safety limit. Daily intake of Cu, Ni, and Cr via consumption of tested cereal crops was found higher than the vegetables. The health quotient revealed that health of local residents is more linked to vegetables than cereal crops. The present findings may be helpful to the policymakers and regulatory authorities to modify the existing policy of wastewater uses in the agriculture and disposal to the natural water bodies. The regular monitoring of heavy metals in the wastewater should also be ensured by the regulatory authorities for their safe disposal to natural water bodies/agriculture in order to reduce the human health risk associated with the degree of heavy metal contaminated suburban food systems.

Assessment of hyaluronic acid-modified imatinib mesylate cubosomes through CD44 targeted drug delivery in NDEA-induced hepatic carcinoma.

This study aimed at the development of hyaluronic acid-functionalised imatinib mesylate cubosomes (HA-IM-CBs) that might be useful in CD44 targeting against hepatic cancer. The HA-IM-CBs had a 130.7 ±â€¯2.92 nm particle size, -31.40 ±â€¯2.76 mV zeta potential, and 76.14 ±â€¯2.69% release. The architecture of HA-IM-CBs was confirmed using HR-TEM and AFM. When compared to plain IM and IM-CBs, in vitro experiments revealed that HA-IM-CBs outperformed by significantly reducing cell viability. DAPI staining and ROS corroborated the apoptotic effects. Biodistribution and Pharmacokinetics studies showedthat HA-IM-CBs exhibit a higher drug concentration in tumour tissue and better pharmacokinetic activity. This is the first study to show that HA-IM-CBs had CD44 targeting activity against HCC. CD44 regulates apoptosis via Bcl-2 family proteins and caspases, which interact with HA. Higher levels of e-NOS, BAD, BAX, and Cyt C and lower expressions of Bcl-xl, i-NOS, and Bcl-2 demonstrated the anti-HCC potential of HA-IM-CBs in qrt-PCR investigations. The remarkable therapeutic potential of HA-IM-CBs began with substantial stimulation of CD44 regulated caspase-mediated mitochondrial apoptotic pathway, accountable for their anti-HCC activity. The perturbed metabolites are restored to acceptable levels as indicated by metabolomic studies (1H NMR). Interestingly, the antineoplastic effect of HA-IM-CBs was proven to be potentially valuable against HCC.

Antioxidant properties, phenolics and flavonoids content of some economically important plants from North-west Indian Himalaya.

The present study investigated antioxidant properties, total phenolic and flavonoid contents in methanol extract of the leaf, stem bark, and fruit of Olea ferruginea Royle, Olea europaea L., and Tilia europaea L. grow naturally in the north-west Indian Himalaya. Phenolics and flavonoids content was found to be maximum in methanol extracts of stem bark and leaf (9.28 mg GAE/g fw and 14.73 mg QE/g fw, respectively) of O. ferruginea plants. Ferric reducing antioxidant power and DPPH radical scavenging activity were found to be maximum in leaf and stem bark (38.88 mM AAE/g fw and 20.31 mM AAE/g fw, respectively) of O. ferrugenia plants, whereas maximum ABTS radical scavenging activity (4.52 mM AAE/g fw) was recorded with stem bark of T. europaea plants. These tree species were found rich in natural compounds and also possess antioxidant activities. Therefore, their pharmaceutical and local uses for the health benefits are suggested.

NMR-based serum and muscle metabolomics for diagnosis and activity assessment in idiopathic inflammatory myopathies.

Objectives: Differentiating smoldering disease activity from weakness due to fatty replacement of atrophied muscle can often be a challenge in the idiopathic inflammatory myositis (IIM). We aimed to identify the metabolic disturbances associated with IIM and if these changes can aid in the assessment of disease activity. Methods: Metabolic profiles of sera (N = 99) and muscle (N = 21) from patients with IIM (ACR-EULAR criteria) were compared with healthy control (HC) samples (N = 75 for serum and N = 12 for muscle tissues) employing 800 MHz NMR (Nuclear Magnetic Resonance) spectroscopy. Metabolic disparity between IIM and HC was established based on Partial Least Squares Discriminant Analysis (PLS-DA) and the discriminatory metabolites were identified based on variable importance in projection (VIP) statistics (P-value < .05, corrected for false discovery rate (FDR)). Results: Serum metabolomics profiles were distinctive in IIM as compared to HC, with a visible shift to anaerobic metabolism (increased lactate, low glucose), oxidative defect (high Phenylalanine/tyrosine), decreased muscle mass (low serum creatinine), increased muscle catabolism (increased branched-chain amino acids), and dyslipidemia (higher lipids, higher very low-density lipoprotein [VLDL]/low-density lipoprotein [LDL] ratio, lower polyunsaturated fatty acid [PUFA]). The sera of active IIM patients were characterized by anaerobic metabolism (low glucose), loss of muscle mass (low creatinine, amino acids), and oxidative defect (high Phenylalanine/tyrosine). Three metabolites (isopropanol, succinate, and glycine) were distinctive in muscle tissue metabolomics. NMR-based serum metabolic disparity was lacking between different clinical subsets of IIM. Conclusion: Serum and muscle tissue metabolomics have the potential to distinguish (a) IIM from HC and (b) active IIM from inactive IIM irrespective of disease subtype.

Assessment of semen quality in pure and crossbred Jersey bulls.

AIM: To compare the seminal attributes of neat, pre-freeze (at equilibration), and post-freeze (24 h after freezing) semen in pure and crossbred Jersey bulls. MATERIALS AND METHODS: Total 36 ejaculates (3 ejaculates from each bull) were collected from 6 pure Jersey and 6 crossbred Jersey bulls and evaluated for various seminal attributes during neat, pre-freeze, and post-freeze semen. RESULTS: The mean (±standard error [SE]) values of neat semen characteristics in pure and crossbred Jersey bulls were recorded such as volume (ml), color, consistency, mass activity (scale: 0-5), and sperm concentration (millions/ml). The extended semen was further investigated at pre-freeze and post-freeze stages and the mean (±SE) values recorded at neat, pre-freeze, and post-freeze semen were compared between pure and crossbred Jersey bulls; sperm motility (80.55±1.70%, 62.77±1.35%, 46.11±1.43% vs. 80.00±1.80%, 65.00±1.66%, 47.22±1.08%), live sperm count (83.63±1.08%, 71.72±1.09%, 58.67±1.02% vs. 80.00±1.08%, 67.91±1.20%, 51.63±0.97%), total abnormal sperm count (8.38±0.32%, 12.30±0.39%, 16.75±0.42% vs. 9.00±0.45%, 12.19±0.48%, 18.11±0.64%), hypo-osmotic swelling (HOS) reacted spermatozoa (71.88±0.77%, 62.05±0.80%, 47.27±1.05% vs. 72.77±1.02%, 62.11±0.89%, 45.94±1.33%), acrosome integrity (89.05±0.83%, 81.33±0.71%, 71.94±0.86% vs. 86.55±0.57%, 78.66±0.42%, 69.38±0.53%), and DNA integrity (99.88±0.07%, 100, 99.66±0.11% vs. 99.94±0.05%, 100, 99.44±0.18%,). The volume, color, consistency, sperm concentration, and initial motility in pure and crossbred Jersey bulls did not differ significantly (p>0.05). The mass activity was significantly (p<0.05) higher in pure Jersey as compare to crossbred Jersey bulls. Live sperm percentage and acrosome integrity was significantly (p<0.01) higher in pure Jersey bulls as compared to crossbred Jersey bulls. However, no statistical difference (p>0.05) was observed in abnormal sperm; HOS reacted spermatozoa and DNA integrity percentage among breeds. CONCLUSION: It may be concluded that the quality of pure Jersey bull semen was comparatively better than the crossbred Jersey bulls.
