A novel proposed classification system for rock slope stability assessment.

The present study introduces "rock slope instability score (RSIS)" a novel classification system for assessing rock slope stability. It takes into account geological and geotechnical parameters, as well as the impact of human activities and triggering parameters, which have become more frequent due to climate change and few of them have been ignored in existing classifications. The study focuses on rock slopes of various lithologies from the Indian Himalayas. The development of this new classification system is based on the examination of 81 different rock slopes from various states of the Indian Himalayas. Extensive field surveys, rock sampling, geotechnical laboratory tests, and ground measurements have been conducted at the various slope sites to establish a comprehensive scoring system for the stability assessment. The distributions of weightage to each parameter have been considered, corresponding to its degree of impact in causing slope instability. Sensitivity analysis of all defined parameters of RSIS system has revealed that the majority of the parameters exhibit a strong positive correlation, with Pearson correlation coefficients ranging from 0.74 to 0.61. However, two parameters, namely discontinuity dip and the relationship between slope & discontinuity direction, gives moderate relationship with correlation coefficient values of 0.48 and 0.41, respectively. To avoid any designer biasness in the system, several individuals gathered data set at different times. The proposed classification system has demonstrated a strong correlation with the actual slope condition, and it is quite promising. The outcome of RSIS classification for studied 81 slopes classified 2 slopes under stable condition, 21 slopes as partially stable, 44 as unstable, and 14 as completely unstable.

Genetic diversity, morphological traits, quality traits and antioxidants potentiality of Coccinia grandis germplasm under rainfed semi-arid region.

The present study was conducted to evaluate the genetic variability for morphological and qualitative traits of Coccinia for development of trait specific lines at ICAR-Central Horticultural Experiment Station (CIAH-RS), Panchmahals (Godhra), Gujarat during 2020-2022. In this study, we evaluated 26 gynoecious accessions to assess the genetic divergence through principal component and cluster analysis. The experiment was carried out in a randomized complete block design with three replications under rainfed semi-arid conditions. High values of PCV and GCV were observed for variables such as NFFP (25.13 and 22.20), PL (23.14 and 20.69), FD (24.01 and 21.46), AFW (22.98 and 20.13), NFPY (26.38 and 24.40), FYP (37.57 and 31.29), FY (35.55 and 33.20), AsC (28.65 and 27.73), Ac (24.32 and 21.06), TSS (37.23 and 35.94), DPPHL (20.71 and 20.38), FRAPL (21.08 and 20.92), TPF(20.81 and 20.45) respectively. High heritability coupled with high genetic advance as per cent of mean was observed for vine length (VL), internodal length (IL), number of female flowers per plant (NFFP), fruit length (FL), peduncle length (PL), fruit diameter (FD), average fruit weight (AFW), number of fruit per plant per year (NFPY), fruit yield per plant (FYP), fruit yield (FY), ascorbic acid (AsC), acidity (Ac), total soluble solids (TSS), total phenols in leaves TPL), total flavonoids in leaves TFL, CUPRAC in leaves (CUPRACL), DPPH in leaves (DPPHL), FRAP in leaves (FRAPL), Total phenols in fruits (TPF), Total flavonoids in fruits (TFF), CUPRAC in fruits (CUPRACF) and DPPH in fruits (DPPHF). The FYP exhibited a significant positive correlation with variables like VL (0.6833), IL (0.2991), NFFP (0.8107), FD (0.5245), AFW (0.6766), NFPY (0.7659), ASC (0.4611), TSS (0.5004) and TPF (0.4281). The estimates of genetic parameters revealed scope for further improvement of fruit yield by selection. Of the eight principal components, PC-I through PC-VIII had eigen values greater than 1 and it accounts 85.02% of the total variation for 26 gynoecious accessions of Ivy gourd. The eigen values of PC-I comprised 5.775% of total variation followed by PC-II (4.250%), PC-III (3.175%), PC-IV (2.588%), PC-V (1.828%), PC-VI (1.447%), PC-VII (1.179%) and PC-VIII (1.013%).The cluster VI and cluster I having highest mean values for most of traits under study. Thus, genotypes from the distinct cluster like cluster VI and I for should be used for selection of parents and varietal improvement for further breeding programme in ivy gourd.

Effects of oral probiotic and lactoferrin interventions on iron-zinc homeostasis, oxidant/antioxidant equilibrium and diarrhoea incidence of neonatal piglets.

The objective of this study was to examine the effects of early-life host specific probiotic and lactoferrin (LF) supplementations on diarrhoea incidence, iron (Fe)-zinc (Zn) balance and antioxidant capabilities in serum of neonatal piglets. A total of eight sow litters obtained from parity matched sows were randomly divided into four groups and assigned to one of the four interventions: control (2.0 ml normal saline), bovine lactoferrin (bLF) (100 mg bLF in normal saline), probiotic (Pb) (1×109 cfu of swine origin Pediococcus acidilactici FT28 strain) and bLF+Pb (both 100 mg bLF and 1×109 cfu of P. acidilactici FT28). All the piglets received supplementations once daily orally for first 7 days of life. The incidence of diarrhoea markedly decreased in bLF group compared to control group. Notably, no incidences of diarrhoea were recorded in Pb and bLF+Pb groups. The Zn and Fe concentrations were significantly increased from day 7 to 21 in bLF and on day 21 in bLF+Pb group. No such changes were noted in Pb group. Total antioxidant capacity (TAC) in serum was significantly increased on days 7 and 15 in bLF group and on days 7 and 21 in bLF+Pb group. Malonaldehyde concentration was markedly reduced from day 7 to 21 in bLF and bLF+Pb groups. The concentrations of nitrate on days 15 and 21 and malonaldehyde on day 7 were significantly higher in Pb group, but mean TAC was unaltered from day 0 to 21. Although no correlation between the incidence of diarrhoea and Zn/Fe and oxidant/antioxidant homeostasis was noted in the Pb group, the supplementation of P. acidilactici FT28 alone was sufficient to prevent the incidence of diarrhoea in neonatal piglets. Taken together, it is concluded that strategic supplementation of P. acidilactici FT28 in early life could help in preventing diarrhoea until weaning of piglets.

Abiotic and biotic stress alleviating effects of the medicinal and aromatic plant-derived product on striped catfish Pangasianodonhypophthalmus.

Intensification of aquaculture production leads to abiotic and biotic stresses, which are further induced by the impact of climate change. Thus, it is important to explore a combined strategy to alleviate multiple stresses in fish. In the present investigation, the removal of nitrogenous metabolites from aquaponics water was studied using products derived from five different locally available medicinal and aromatic plants (MAPs) namely banana stem (Musa Accuminata), Aloe vera, Mint (Minata sepicata), Indian beech/Pongameoil-tree/Karanj (Pongamia pinnatum), and Coat Button/Mexican daisy/Dagadipala (Tridax procrumbens) in the batch experiment for 24 h. A reduction of 91-94% in the ammonia level and 75-80% removal of nitrite-N in the treatments with products derived from mint, banana stem, and aloe vera has been observed. Mint product was also found to be bactericidal against fish pathogenic bacteria. Based on this dual function of mint, further study was conducted under wet-lab conditions to evaluate the possible protective role of the mint-based product in dry powder form against abiotic stresses caused by nitrogenous toxicants for 24 h and 45 days multiple stresses caused by nitrogenous toxicants in freshwater stocked with eight fingerlings of Pangasianodon hypophthalmus of the initial weight of 8 ± 0.5g for 24 h and 8.82 ± 0.75g for 45 days. The results revealed that mint-derived plant product has better anti-stress properties in terms of their bioremediation effectiveness in lowering ammonia and nitrite. Mint also improved the fish growth performance with better physiological responses and anti-oxidative status and reduced the cellular metabolic stress in fish reared under ammonia, as further indicated by reduced oxidative stress parameters, and tissue biochemical indices. Overall, mint showed its main properties as a growth promoter, and immune enhancer, where this medicinal plant product acts as a bioremediation and antibacterial agent to the host immune system. This has potential applications in the environmental and health management of aquaculture.

Starch bio-based composite active edible film functionalized with Carum carvi L. essential oil: antimicrobial, rheological, physic-mechanical and optical attributes.

In the present study, the antimicrobial, rheological, mechanical, barrier and optical properties of Carrageenan and Manihot esculenta (composite) starch biobased edible film incorporated with caraway (Carum carvi L.) essential oil (EO) were investigated. The Minimum Inhibitory Concentration (MIC) of caraway oil against B. cereus, E. coli, P. aeruginosa and S. aureus were found to be 0.6, 1.4, 1.4 and 0.8% respectively. The Gas Chromatography- Mass Spectroscopy (GC-MS) of caraway EO expressed a distinct chromatogram peak for phenolic compounds. Rheological results of Film-Forming Solution (FFS) revealed solid-like viscoelastic behavior. Incorporation of caraway EO in the film caused significant (P < 0.05) increase in moisture, moisture absorption, bio-degradability in terms of film solubility, L value, total color difference (ΔE), haziness and transparency value, however, significantly (P < 0.05) decreased tensile strength and whiteness index were observed. The zone of inhibition of caraway EO incorporated films against all test bacteria were highly significant (P < 0.01) than control whereas antibacterial activity was found more towards gram-positive bacteria than gram-negative bacteria. No significant (P>0.05) changes in thickness, density, water activity, swelling, elongation at break, water vapor transmission rate, a and b value were observed with increasing caraway EO concentration. These results with some good rheological, physic-mechanical, antimicrobial and optical characteristics suggest the application of such active film into a variety of foods with improved food safety and quality.

Differential proteomic profile of X- and Y- sorted Sahiwal bull semen.

The identification of differential proteins between X- and Y-sperm may be useful for immunological sexing of sperm. Hence, the present study was aimed to compare the protein profile of X- and Y-sorted Sahiwal bull semen using SDS-PAGE and Liquid Chromatography coupled with Mass Spectrometry (Nano LC-MS). Semen sample (n = 6) were categorized into three groups i.e., group I (X-sorted), group II (Y-sorted) and control group (both X- and Y- sperms). SDS PAGE revealed specific proteins of molecular weight between 18 and 24 kDa and between 30 and 37 kDa were present in X-sorted sperms. Also, band corresponding to 25 kDa was specific to Y-sorted sperms. Data obtained from Nano LC/MS is analysed by search engine database i.e., MASCOT and SEQUEST HT. Total, 241 proteins were identified, out of which 113 were differentially expressed between X- and Y-sorted sperms, in which 54 proteins showed at least two unique peptides. Out of 54 proteins, 27 were upregulated in X-sorted sample, 3 were upregulated in Y-sorted sample and 24 were differentially downregulated. Highly upregulated protein in X-sperm viz. Armadillo repeat containing 12 protein, NDC1 transmembrane nucleoporin, ß-nerve growth factor, C-type natriuretic peptide, Nucleobindin-2, Phosphoglycerate mutase 2, Calmodulin along with one uncharacterised protein having accession number F1MN9 may have potential to be used as biomarker for separating X and Y sperm.

Long-term conservation agriculture and best nutrient management improves productivity and profitability coupled with soil properties of a maize-chickpea rotation.

Conservation agriculture (CA)-based practices have been promoted and recouped, as they hold the potential to enhance farm profits besides a consistent improvement in soil properties. A 7 years' field experiment consisting of three crop establishment practices viz., zero-till flatbed (ZTFB), permanent beds (PNB), conventional system (CT) along with the three-nutrient management; nutrient expert-based application (NE), recommended fertilization (RDF), and farmers' fertilizer practice (FFP), was carried out from 2013 to 2020. The CA-based practices (ZTFB/PNB) produced 13.9-17.6% greater maize grain-equivalent yield (MGEY) compared to the CT, while NE and RDF had 10.7-20% greater MGEY than the FFP. PNB and ZTFB gave 28.8% and 24% additional net returns than CT, while NE and RDF had 22.8% and 17.4% greater returns, respectively over FFP. PNB and ZTFB had 2.3-4.1% (0.0-0.20 m soil layers) lower bulk density than the CT. Furthermore, microbial biomass carbon (MBC) increased by 8-19% (0.0-0.50 m soil layers) in ZTFB/PNB over the CT, and by 7.6-11.0% in NE/RDF over FFP. Hence, CA-based crop establishment coupled with the NE or RDF could enhance the yields, farm profits, soil properties of the maize-chickpea rotation, thereby, could sustain production in the long run.

Comparative retrospective analysis of locoregional recurrence in unselected breast cancer patients treated with conventional versus hypofractionated radiotherapy at a tertiary cancer center?

BACKGROUND: Role of hypofractionated radiotherapy (HFRT) in early breast cancer is established; comparatively, there are limited data for HFRT in locally advanced breast cancer (LABC). We report the impact of HFRT in unselected breast cancer patients in comparison with historically treated patients with conventional fractionated radiotherapy (CFRT). PATIENTS AND METHODS: Records of 463 breast cancer patients treated between January 09 and July 13 with CFRT (50 Gy/25 fr) or HFRT (42.4 Gy in 16 fractions or 40 Gy in 15 fractions) in two sequential periods were retrospectively reviewed. The analysis was done in August 2018. The primary endpoint was to compare the differences in locoregional recurrence rate. RESULTS: Of the 463 patients, 209 received CFRT and 254 received HFRT. The median age was 48 years (interquartile range: 40-56), premenopausal (CFRT: 23% vs. HFRT 39%, P = 0.005). The most common pathology was infiltrating ductal carcinoma (81%) with Grade III tumors (45%), estrogen receptor (+) was seen in 44%, triple-negative breast cancer in 34%, and Her2Neu (3+) were seen in 27%. Two hundred and fifty-four patients (54.5%) had undergone breast-conserving surgery (BCS) and 209 patients (45%) modified radical mastectomy (MRM). Nodal radiotherapy was delivered in 76% versus 64% in patients receiving CFRT versus HFRT, respectively (P = 0.005). With a median follow-up of 46 months in CFRT and 57 months in HFRT, 9/209 (4.3%) patients in CFRT and 7/254 (2.7%) in HFRT had locoregional relapse (LRR). The 4 years#39; actuarial local recurrence-free survival (LRFS) in CFRT versus HFRT was 95% versus 97% (P = 0.37). The mean estimated LRFS (local relapse-free survival) for CFRT is 113.4 months and for HFRT 94.2 months (P = 0.3). CONCLUSIONS: The risk of local recurrence among patients of breast cancer treated with HFRT after BCS or MRM was not worse when compared to CFRT.

Over-expression of Caj1, a plasma membrane associated J-domain protein in Saccharomyces cerevisiae, stabilizes amino acid permeases.

Hsp70: J-domain protein (JDP) machines, along with the cellular protein degradation systems play a central role in regulating cellular proteostasis. An equally robust surveillance system operates at the plasma membrane too that affects proper sorting, stability as well as the turnover of membrane proteins. Although plausible, a definitive role of the Hsp70: JDP machine in regulating the stability of plasma membrane proteins is not well understood in Saccharomyces cerevisiae. Here we show that a moderate over-expression of Caj1, one of the thirteen JDPs residing in the nucleo-cytosolic compartment of S. cerevisiae reduced the cold sensitivity of tryptophan auxotrophic yeast cells by stabilizing tryptophan permeases, Tat1 and Tat2 in a J-domain dependent manner. Concomitantly, higher Caj1 levels also caused slow growth and increased plasma membrane damage at elevated temperatures possibly due to the stabilization of thermolabile plasma membrane proteins. Finally, we show that although majorly cytosolic, Caj1 also co-localizes with the membrane dye FM4-64 at the cellular periphery suggesting that Caj1 might interact with the plasma membrane. Based on the results presented in this study, we implicate the Hsp70: Caj1 chaperone machine in regulating the stability or turnover of plasma membrane proteins in budding yeast.

Interplay of oxidative stress and antioxidant bio markers in oil adjuvant Brucella melitensis vaccinated and challenged mice.

The intracellular nature of Brucella leads to rise in oxidative stress due to bacterial invasion, particularly at the site of predilection spleen and lymph nodes. The present study aimed to evaluate the erythrocytic and tissue specific oxidative stress responses induced during oil adjuvant killed Brucella melitensis vaccination. The results of the study clearly implicated a significant increase in level of catalase, and superoxide dismutase (SOD) activity and lipid peroxidation (LPO), and total protein content in erythrocytes after vaccination. The activity of glutathione-S-transferase (GST) was unaltered during the period of experiment. The catalase activity and GSH content was significantly increased in lung and spleen tissues. The tissues GST levels increased significantly in all tissues, while tissue SOD level increased significantly only in lung tissues. Thus, it can be inferred that oil adjuvant based Brucella vaccine induces negligible signs of inflammatory pathophysiology and supports the development of significant level of protection against virulent Brucella challenge.

Bacillus clausii UBBC-07 reduces severity of diarrhoea in children under 5 years of age: a double blind placebo controlled study.

Acute diarrhoea is one of the leading causes of mortality in infants and young children. Evidence suggests that probiotics can reduce diarrhoea duration. As the effects of probiotics are strain specific, the effect of Bacillus clausii UBBC-07, a safe probiotic strain in the treatment of acute diarrhoea in children was studied. The double blind, randomised, placebo-controlled, parallel group multicentric study was conducted at two outpatient facility sites in Lucknow, India. Children aged six months to five years suffering from acute diarrhoea, were randomly assigned to receive either probiotic (B. clausii UBBC-07) spore suspension or placebo suspension twice daily apart from oral rehydration solution (ORS). The duration of treatment was for five days with a follow -up until the 10th day. Outcomes evaluated were duration and frequency of diarrhoea, consistency of stool, fever and vomiting. The duration of diarrhoea was significantly shorter (P<0.05) in patients who received B. clausii suspension (75.66±13.23 h) than in placebo treated group (81.6±15.43 h). The average daily number of stools (frequency) was 8.67±3.42 at baseline in treatment group receiving B. clausii and 8.53±3.19 in placebo group. By day 4, there was a significant reduction (P<0.01) in frequency of stools in probiotic treated group (3.46±0.66) as compared to placebo group (4.57±1.59). Improvement in stool consistency was also observed in the probiotic treated group as compared to the placebo group. There was no effect on vomiting and duration of fever. B. clausii UBBC-07 significantly decreased the duration and frequency of diarrhoea as compared to placebo indicating effectiveness of strain in the treatment of acute diarrhoea in children and could be a safe alternative to antibiotics.

Co-evolution of spliceosomal disassembly interologs: crowning J-protein component with moonlighting RNA-binding activity.

Spliceosome disassembly is catalyzed by the NineTeen-related (NTR) complex, which is constituted by several proteins, including Cwc23, Ntr1, and Ppr43. Cwc23 is an essential J-protein in Saccharomyces cerevisiae that recruits Ntr1, an NTC-related G-patch protein, to the spliceosome. Ntr1 interacts with Prp43, a DExD/H box RNA helicase protein, which facilitates the disassembly of spliceosomal intermediates. The interaction between Ntr1 and Prp43 is conserved and crucial for the disassembly process. However, the J-protein component of this complex is not studied in other eukaryotes. In silico analysis supported by results of yeast complementation and two-hybrid studies suggests that while Prp43 is highly conserved, both Ntr1 and Cwc23 are co-evolving components of the disassembly triad. The J-domain of Cwc23, which is otherwise dispensable for its function, is highly conserved, whereas the functionally critical C-terminus has significantly diverged in Cwc23 orthologs. Some eukaryotic orthologs of Cwc23 contain a distinct RNA recognition motif at their C-terminus and are able to bind RNA in vitro. Based on the results presented in this study, we propose that RNA-binding activity in some eukaryotic orthologs of Cwc23 might provide additional functional diversity or robustness to the J-protein/Hsp70 machine in spliceosomal remodelling processes.

BACKGROUND: Total thyroidectomy (TT) with a uniform technique of capsular dissection (CD) is the preferred technique worldwide. The aim of study is to analyze the impact of uniform technique of CD for done as primary surgery at an endocrine surgery training centre. PATIENTS AND METHODS: Retrospective review from 1995 to 2009. Data collected from hospital records and follow-up. RESULTS: One thousand and thirty-eight cases were included, with mean age 42.91 ± 13.48 years; male:female - 1:2.2; mean duration of goiter - 99.83 ± 105.1 months; 67.8% were euthyroid and 30.7% - hyperthyroid at initial presentation; 35.5% were malignant. Surgery includes TT alone - 77.7% and TT with lymph nodes dissection - 22.3%; sternotomy required in 1.2% and thoracotomy in 0.1%; tracheomalacia present in 3.9%; however, tracheostomy required in 4.5% and parathyroid autotransplantation in 21%; Peroperative mean gross gland weight was 124.34 ± 129.85 g. Complications include hypocalcemia (temporary - 35.9%; permanent - 1.3%); recurrent laryngeal nerve palsy (temporary - 2.7%; permanent - 91%); hemorrhage - 1.3%; and various others. CONCLUSION: TT with uniform technique of CD is a safe procedure. Certain risk factors may predispose to complications, which can be avoided and managed adequately if anticipated beforehand.

Purification, developmental expression, and in silico characterization of α-amylase inhibitor from Echinochloa frumentacea.

Barnyard (Echinochloa frumentacea) and finger (Eleusine coracana) millet growing at northwestern Himalaya were explored for the α-amylase inhibitor (α-AI). The mature seeds of barnyard millet variety PRJ1 had maximum α-AI activity which increases in different developmental stage. α-AI was purified up to 22.25-fold from barnyard millet variety PRJ1. Semi-quantitative PCR of different developmental stages of barnyard millet seeds showed increased levels of the transcript from 7 to 28 days. Sequence analysis revealed that it contained 315 bp nucleotide which encodes 104 amino acid sequence with molecular weight 10.72 kDa. The predicted 3D structure of α-AI was 86.73% similar to a bifunctional inhibitor of ragi. In silico analysis of 71 α-AI protein sequences were carried out for biochemical features, homology search, multiple sequence alignment, phylogenetic tree construction, motif, and superfamily distribution of protein sequences. Analysis of multiple sequence alignment revealed the existence of conserved regions NPLP[S/G]CRWYVV[S/Q][Q/R]TCG[V/I] throughout sequences. Superfam analysis revealed that α-AI protein sequences were distributed among seven different superfamilies.

Influence of boron supplementation on performance, immunity and antioxidant status of lambs fed diets with or without adequate level of calcium.

Little is known about biological significance of effects of dietary Boron (B) and Calcium (Ca) interaction on health and production of farm animals. This is a preliminary investigation to evaluate the effects of B supplementation in lambs fed diets with (normal) or without adequate (low) levels of Ca. Twenty-four crossbred ram lambs were randomly distributed into four groups with six animals each in a 2x2 factorial design namely, normal-Ca diet (NCa) and low-Ca diet (LCa) fed without or with 40 ppm B (NCaB-40 and LCaB-40). The lambs were fed paddy straw and hybrid napier hay-based total mixed ration (60 roughage: 40 concentrate) during 180 days experimental period. Compared to control, the LCa diet lowered (P<0.01) average daily gain of lambs, but B-supplementation (LCaB-40) of the same nullified the effect. The lowered (P<0.05) total antioxidant activity and humoral immune response in lambs fed LCa diet were restored (P>0.05) to become at par with the control (NCa) upon supplementation of B (LCaB-40). The mRNA expression of SOD1 was lowered (P<0.05) due to LCa diet feeding which too was normalized on B-supplementation to become at par (P>0.05) with the control (NCa). Further, B-supplementation restored lowered (P<0.05) SOD1 gene expression on LCa diet, but enhanced (P<0.05) that in NCaB-40 group, when compared to the control (NCa) diet fed animals. However, these variations were not reflected in the SOD activity in the erythrocytes. The cell-mediated immune response was higher (P<0.05) in lambs fed LCa and LCaB-40 groups and there was no significant interaction between the levels of either Ca or B in diets with the period of immune response measurement. B- supplementation of LCa diet ameliorated tissue degenerative changes in liver and kidney. It was concluded that feeding LCa diet to lambs resulted in reduced growth rate, total antioxidant activity, humoral immune response along with degenerative changes in liver and kidney tissues, but B-supplementation of such diet restored most of these changes and ameliorated histopathological alterations.

Impact of feeding chromium supplemented flaxseed based diet on fatty acid profile, oxidative stability and other functional properties of broiler chicken meat.

A total of 240 broiler chicken of same hatch with uniform weight were used in a biological experiment with completely randomized design to investigate the effects of incorporating organic chromium (Cr) in flaxseed meal based diet on the fatty acid profile, oxidative stability and functional properties of broiler chicken meat. Five diets were formulated as per the recommendations of BIS (Nutrient requirements for poultry 13: 9863, Bureau of Indian Standards, New Delhi, 1992) in which flaxseed meal was used to replace 10% of soyabean in basal diet and four levels of Cr (0.0, 0.5, 1.0 and 1.5 mg/kg diet) as Cr-picolinate were used. The results revealed that flaxseed feeding significantly increased the percentage of unsaturated fatty acids, including MUFA, PUFA, ω-3, ω-6 fatty acids and ω-3:ω-6 and PUFA:SFA ratios, whereas, significant decline was seen in saturated fatty acids and no effect of Cr was observed on the fatty acid profile of broiler chicken. Flaxseed feeding significantly reduced the cholesterol and fat percentage of meat, whereas, significant progressive reduction was observed with increasing Cr levels. The combination of 10% flaxseed with 1.0 mg Cr/kg diet increased the final pH of broiler meat. The addition of flaxseed significantly reduced water holding capacity, extract release volume and antioxidant potential of broiler meat, whereas, increasing Cr supplementation progressively increased them. Flaxseed feeding significantly increased the drip loss and lipid peroxidation of broiler meat, whereas, Cr supplementation decreased them. It was concluded that inclusion of 10% flaxseed and 1.5 mg Cr/kg diet results in desirable fatty acid profile, oxidative stability and functional properties of broiler chicken meat.

Rehabilitation of Nose following Chemical Burn Using CAD/CAM Made Substructure for Implant Retained Nasal Prosthesis: A Clinical Report.

Insufficient knowledge of medical chemicals and their improper use have destructive effects. Accidental exposure to chemicals on facial tissue may result in large facial defect. For ages the tradition of piercing nose is common but improper use of unknown chemical for piercing has deleterious effect. Mostly rhinectomy defects are acquired caused by trauma or malignant diseases. Prosthetic rehabilitation is the preferred treatment of choice for any large rhinectomy defects as medical and surgical interventions are ineffective in developing esthetics. Main concern with the prosthesis for such defects is retention. This article describes rehabilitation of a patient with large size nasal defect created by chemical burn in childhood during piercing. Implant retained customized silicone nasal prosthesis was fabricated using simple O-ring attachments and innovative modified polyamide acrylic resin substructure acting as skeleton.

Occurrence of multidrug resistant Escherichia coli in groundwater of Brij region (Uttar Pradesh) and its public health implications.

AIM: The study evaluates the microbial as well as physicochemical pollution of groundwater of Brij region of Uttar Pradesh, a major tourist destination in the country along with estimating the drug resistance evident in the isolated Escherichia coli. MATERIALS AND METHODS: A total of 60 samples of groundwater were collected from six different sites and assessed for physicochemical (pH, color, taste, turbidity, total dissolved solids [TDS], total hardness [TH], chlorides, fluorides, nitrates, and iron) and microbiological parameters (standard plate count [SPC], most probable number test [MPN], E. coli). RESULTS: A majority of the samples were found to be out of the range for most of the parameters except iron. Particularly, high values of TDS (up to 9000 ppm), TH (1500 mg/L), chlorides (3250 mg/L), fluorides (2.5 mg/L), and nitrates (100.2 mg/L) were observed at most of the sites in the region highlighting the fact that groundwater of the area is not potable. Samples were turbid and salty to taste. High SPC values, up to 3500 colony-forming unit/ml and coliforms beyond BIS range were found in 40% samples suggesting gross microbial contamination. Only 2 sites (G3 and G5) had low MPN values. Overall 16 (26.67%) E. coli were isolated with 3 (18.75%) producing red colonies on conge red agar, hence supposed to be pathogenic. No E. coli O157:H7 was isolated. High antimicrobial resistance was observed against amoxicillin and erythromycin, whereas E. coli isolates were sensitive toward cefotaxime-clavulanic acid and imipenem. 12 isolates (75%) were multidrug resistant (MDR) with MDR index >20%, and 2 isolates (12.5%) were found to be extended spectrum beta-lactamases positive. CONCLUSION: Groundwater is considered to be a safe option for potable water but it is obvious from the findings of this study that considerable physicochemical and microbial contamination is there in groundwater samples of Brij region. The occurrence of MDR E. coli in these waters is a matter of great public health concern.

The use of large and small subunits of ribosomal DNA in evaluating phylogenetic relationships between species of Cornudiscoides Kulkarni, 1969 (Monogenoidea: Dactylogyridae) from India.

Two partial regions of ribosomal DNA (28S and 18S) were used to evaluate genetic variations among the species of Cornudiscoides, viz. C. proximus, C. geminus and C. agarwali, all parasites of Mystus vittatus (Bagridae) from River Gomati, Ganges River basin, India. Our findings demonstrated that both the large and small ribosomal subunits are useful for species identification and genetic characterization of parasites, leading to resolution of inter/intra-relationships at generic and specific levels. The secondary structures of all three species for 28S and 18S rRNA genes contained exact pattern matches (EMPs) displaying the high degree of similarity among them. The phylogenetic analyses within the members of Dactylogyridae demonstrated that species of Cornudiscoides cluster together for 28S rRNA and 18S rRNA genes.
