Plummeting toxic contaminates from water through phycoremediation: Mechanism, influencing factors and future outlook to enhance the capacity of living and non-living algae.

Freshwater habitats hold a unique role in the survival of all living organisms and supply water for drinking, irrigation, and life support activities. In recent decades, due to anthropogenic activities, deterioration in the water quality has been a long-lasting problem and challenge to the scientific fraternity. Although, these freshwater bodies have a bearable intrinsic capacity for pollution load however alarming increase in pollution limits the intrinsic capacities and requires additional technological interventions. The release of secondary pollutants from conventional interventions further needs revisiting the existing methodologies and asking for green interventions. Green interventions such as phycoremediation are natural, eco-friendly, economic, and energy-efficient alternatives and provide additional benefits such as nutrient recovery, biofuel production, and valuable secondary metabolites from polluted freshwater bodies. This systemic review in a nut-shell comprises the recent research insights on phycoremediation, technological implications, and influencing factors, and further discusses the associated mechanisms of metal ions biosorption by living and non-living algae, its advantages, and limitations. Besides, the article explores the possibility of future research prospects for applicability at a field scale that will help in the efficient utilization of resources, and improved ecological and health risks.

Ranking based formula optimization, quality investigation, and real-time shelf-life prediction of ready-to-eat ricebean (Vigna umbellata) curry.

Ricebean (Vigna umbellata) is an underutilized bean of South and South-East Asia, was exploited to formulate the ready-to-eat curry by using thermal processing technology. Eleven types of RTE ricebean curries (RBCs) namely RBC1, RBC2, RBC3, RBC4, RBC5, RBC6, RBC7, RBC8, RBC9, RBC10, RBC11 were developed by varying the proportion of tomato paste, onion paste, and coriander powder after thermal processing at 121 °C (15 psi) for 20 min. Out of these, the best quality curry was selected based on the total product ranking score (TPRS) which was calculated from the curry quality parameters such as consistency, pH, loss due to sorption onto the inner surface of the retort pouch (LOSS), and sensory (overall acceptability-OAA). Among the curries, RBC2 secured the highest value of TPRS, named it as RTE-RBC and was used to study the physico-chemical, textural, nutritional, microbial, sensory parameters and storage stability. The DPPH-antioxidant activity of RTE-RBC was 2.47 µM BHA/g which was due to the presence of bioactive phytochemicals such as polyphenol, flavonoids, lycopene, gingerol, É£-Oryzanol, and capsaicin. It was observed that the in-vitro protein/carbohydrate digestibility, in-vitro calcium bioavailability and real-time shelf-life (predicted) of RTE-RBC were 85%, 54%, and one year, respectively.

Optimization of instant foxtail millet based khichdi by using response surface methodology and evaluation of its shelf stability.

Instant foods are a great convenience in today's fast moving world, aiding to reduce the time spent on the cooking process, along with the added advantage of long shelf life and ease to carry. Ingredient composition was finalized by optimizing the design variables (instantised foxtail millet, instantised green gram dal and oat flakes) using Central Composite Rotatable Design besides suitable fat and spices for the development of instant foxtail millet khichdi. Over all acceptability and water holding capacity were considered as the responses for the experimental design. The developed quick cooking (jiffy) product possessed calorific value of 525.11 kcal/100 g with good rehydration/ reconstitution properties within 4 min. Shelf stability of the khichdi packed in polypropylene (75µ) and metallised polyester (90µ) pouches was evaluated in terms of chemical, microbiological and sensorial changes. The product was found to be shelf stable for 6 months of storage in metallised polyester.

Alterations of hemogram, serum biochemistry, oxidative/nitrosative balance, and copper/zinc homeostasis in dromedary camels naturally infected with poxvirus.

Camel pox (CMLP), a contagious viral disease of camels, causes considerable economic loss in terms of milk, meat, wool, and leather production besides reduction of draught power. The effect of spontaneous CMLP infection on hemogram, oxidative/nitrosative imbalance, and trace mineral homeostasis has not been studied earlier in dromedary camels. In the current study, hemogram, serum biochemistry, oxidant/antioxidant imbalance, and zinc (Zn)-copper (Cu) homeostasis were evaluated in healthy and pox-infected camels. The CMLP was confirmed from pooled samples of vesicular fluid, oral mucosa, and skin samples by polymerase chain reaction (PCR) targeting the C18L gene of CMLP virus. Hemogram was performed manually in whole blood. The serum was analyzed for biochemistry. The oxidative/nitrosative imbalance was measured by determining the concentrations of malondialdehyde (MDA), nitrite and nitrate (NOx), and glutathione S-transferase (GST) activity in serum. Simultaneously, copper (Cu) and zinc (Zn) concentrations were measured in serum. A pronounced leucopenia (p = 0.019), lymphopenia (p = 0.005), and hypoproteinemia (p = 0.014) were noted in CMLP-infected camels compared to healthy animals. The significant elevation of the MDA (p = 0.005) and NOx (p = 0.044) concentrations in serum of CMLP-infected indicated marked oxidative stress during the disease. The zinc concentration (p = 0.014) in CMLP-infected camels was significantly lower than healthy camels. The study supports that oxidative/nitrosative imbalance and Cu-Zn homeostasis are compromised and related to the pathophysiology of CMLP infection. The finding will be helpful to veterinary clinicians to adopt effective therapeutic strategies using antioxidants and trace minerals during CMLP outbreak. The timely vaccination and bio-security will be the mainstay for prevention of the diseases.

Influence of processing methodology on phenolic acid content, fatty acid profile and oxidative stability of Macrotyloma uniflorum.

Study was conducted to determine the influence of different cooking methods namely pressure, flaking, infra-red, microwave and extrusion processing on rate of oxidative stability, fatty acid profile and functional properties of horse gram. The rate of auto-oxidation was significantly (p < 0.05) affected during storage and found maximum at 0.00 aw and minimum at 0.33 aw for both varieties namely GPM-6 and PAIYUR-2. The extrusion processed grains were more susceptible to auto-oxidation. The iron content of grain increased significantly (p < 0.05) during extrusion (1.22 ± 0.50 to 1.65 ± 0.15 mg 100 g-1 for PAIYUR-2 and 1.19 ± 0.45 to 1.59 ± 0.12 mg 100 g-1 for GPM-6). Whereas, tocopherol content decreased during extrusion (8.05 ± 0.15 to 2.28 ± 0.23 mg 100 g-1 for PAIYUR-2 and 6.48 ± 0.46 to 1.68 ± 0.15 mg 100 g-1 for GPM-6). Ellagic (12.36 ± 0.35 and 10.71 ± 0.29 mg 100 g-1), vanillic (15.20 ± 0.23 and 12.48 ± 0.18 mg 100 g-1), and coumaric acid (14.68 ± 0.71 and 8.97 ± 0.66 mg 100 g-1) were the major phenolic acids whereas, linoleic (35.53 ± 0.30 and 35.46 ± 0.19%), palmitic (26.08 ± 0.26 and 25.97 ± 0.33%), and linolenic acid (13.44 ± 0.18 and 10.13 ± 0.21%) were the major fatty acids present in raw grain for PAIYUR-2 and GPM-6 respectively. Phenolic and fatty acids were significantly (p < 0.05) affected during processing. The oxidative stability of microwave processed grains was maximum whereas, extrusion processed grains showed minimum oxidative stability during storage. Study explicitly describes that native grains and the grains which did not undergo destruction of naturally present cellular structure, were less prone to oxidation. The oxidation rate of grains was found dependent on composition, processing and storage environment of grains. Hence, all these factors need to be considered to ensure the stability of processed food during storage.

Influence of multigrain premix on nutritional, in-vitro and in-vivo protein digestibility of multigrain biscuit.

Effect of addition of multigrain premix (MGP) prepared using a combination of cereals, pulses and oilseeds at 40% level, on nutritional properties of multigrain biscuit, its in-vitro and in-vivo protein digestibility and protein profiling were studied. The incorporation of MGP significantly increased the protein content (from 7.37 to 16.61%), insoluble dietary fiber (from 1.71 to 6.67%), soluble dietary fiber (from 0.46 to 2.42%). The significant increase in the levels of isoleucine (ND-34.79%), methionine (0.04 to 7.65%), tryptophan (0.22 to 5.95%) valine (0.38 to 16.58%), lysine (0.36 to 7.32%), and threonine (0.51 to 7.2%) was observed, whereas fatty acid profile of MGP incorporated biscuits showed increased polyunsaturated fatty acids and decreased saturated fatty acids. The vitamin-mineral profile of MGP incorporated biscuits showed increased the thiamin (0.07-0.21 mg/100 g), riboflavin (0.09-0.28 mg/100 g), calcium (12.89-45.28 mg/100 g) and iron (1.13-3.47 mg/100 g) contents. The in-vitro protein digesibility of multigrain and control biscuits indicated that the proteins present in multigrain biscuits had high digestibility (71.73%) as compared to control biscuit (38.13%). The in-vivo studies indicated that, the protein quality of multigrain biscuits was comparable with casein protein with high protein efficiency ratio of 3.02. The electrophoretic pattern of multigrain biscuits showed subunit molecular weight distribution of different protein units and aggregation of protein bands at high molecular weight region of 85 to 166 kD. The outcome of the study indicated the possibility of utilising MGP to improve the overall nutritional quality of biscuits.

Isolation and analysis of the molecular epidemiology and zoonotic significance of Mycobacterium tuberculosis in domestic and wildlife ruminants from three states in India.

The majority of tuberculosis cases in ruminants are caused by Mycobacterium bovis (MB). However, in this study, the authors reported the isolation of Mycobacterium tuberculosis (MT) from bovine milk, nasal swabs and post-mortem tissue samples (n = 841) collected from cattle and buffaloes in the states of Telangana, Maharashtra and Gujarat in India in the period from 2010 to 2015. The isolates (n = 7) were confirmed as Mycobacterium due to their growth characteristics and colony morphology in a commercial liquid medium Mycobacterial Growth Indicator Tube (MGIT)™ employing the BD BACTEC™ MGIT™ 960 system and the Löwenstein-Jensen (LJ) medium supplemented with glycerol but not with sodium pyruvate, and BD-DIFCO™ Middlebrook 7H10 agar containing oleic albumin dextrose catalase (OADC). These isolates were initially identified as members of the M. tuberculosis complex (MTC) using a commercial nested polymerase chain reaction (PCR) kit based on the IS6110 MTC specific nucleotide sequence. The isolates were confirmed as MT using three commercial line probe assay kits, were further genotyped, and the spoligotypes identified were of East African Indian (EAI) 3_IND, EAI5, Central-Asian (CAS) 1_DELHI, U and T1 lineages. Two MT isolates from one antelope (Antilope cervipara) andone gazelle (Gazella bennettii) from Gujarat, which were identified previously, were spoligotyped during this study and identified as belonging to EAI3_IND and EAI5 lineages, respectively. The epidemiological significance and zoonotic implications of regional presence and documentation of the same or two differents poligotypes in different species within the family Bovidae as well as humans is discussed.

La majorité des cas de tuberculose chez les ruminants sont dus à Mycobacterium bovis. Néanmoins, les auteurs rapportent les résultats d'une étude réalisée de 2010 à 2015 en Inde (états de Telangana, Maharashtra et Gujarat), au cours de laquelle Mycobacterium tuberculosis a été isolé à partir de lait de vache ainsi que d'écouvillons nasaux et de prélèvements tissulaires postmortem (n = 841) collectés sur des bovins et des buffles. L'appartenance des isolats au genre Mycobacterium a été confirmée par l'observation des caractéristiques de croissance des colonies et de leur morphologie dans un milieu de culture liquide du commerce (Mycobacterial Growth Indicator Tube [MGIT]™ : tube avec indicateur de croissance mycobactérienne) en utilisant l'automate BD BACTEC™MGIT™ 960 et un milieu de Lowenstein-Jensen additionné de glycérol mais sanspyruvate de sodium, ainsi qu'une gélose BD-DIFCO™ Middlebrook enrichie en acide oléique, albumine, dextrose et catalase (OADC). Dans un premier temps, les isolats ont été identifiés comme étant des membres du complexe M. tuberculosisau moyen d'une amplification en chaîne par polymérase nichée ciblant la séquence nucléotidique spécifique IS6110 du complexe M. tuberculosis. Trois kits commerciaux d'analyse de souches ont permis d'identifier les isolats comme étant M. tuberculosis ; il a ensuite été procédé à l'analyse des génotypes des souches de spoligotypes, lesquelles appartenaient aux lignées East African Indian (EAI) 3_IND,EAI5, Central-Asian (CAS) 1_DELHI, U et T1. Les spoligotypes de deux isolats de M. tuberculosis obtenus précédemment, provenant respectivement d'une antilope(Antilope cervipara) et d'une gazelle (Gazella bennettii) de l'état de Gujarat ont été analysés lors de la présente étude et identifiés comme étant respectivement de lignée EAI3_IND et EAI5. Les auteurs analysent l'importance épidémiologique et la portée zoonotique de la présence rapportée dans la région du même spoligotype ou de deux spoligotypes différents chez des espèces différentes de la famille des Bovidés ainsi que chez l'homme.

La mayoría de los casos de tuberculosis que afectan a los rumiantes son causados por Mycobacterium bovis (MB). En este estudio, sin embargo, los autores dan cuenta del aislamiento de Mycobacterium tuberculosis (MT) en muestras de leche, frotis nasales y tejidos obtenidos post-mortem (n = 841) de ganado vacuno y búfalos de los estados de Telangana, Maharashtra y Gujarat (India) entre 2010 y 2015. Se confirmó que los microorganismos aislados(n = 7) eran micobacterias por sus características de crecimiento y la morfología de las colonias cultivadas en medio líquido comercial Mycobacterial Growth Indicator Tube (MGIT)™ empleando el sistema BD BACTEC™ MGIT™ 960 y el medio Löwenstein-Jensen (LJ) suplementado con glicerol, pero no con piruvato sódico, y agar BD-DIFCO™ Middlebrook 7H10 con ácido oleico, albúmina, dextrosa y catalasa (OADC). Mediante una PCR (reacción en cadena de la polimerasa) anidada comercial basada en la secuencia nucleotídica IS6110 específica del complejo, se empezó por determinar que esos microorganismos pertenecían al complejo M. tuberculosis (MTC). Tras confirmar que se trataba de M. tuberculosis empleando tres ensayos comerciales con sondas en línea, se procedió a caracterizar su genotipo, lo que sirvió para identificar espoligotipos correspondientes a los siguientes linajes: East African Indian (EAI) 3_IND, EAI5, Central-Asian (CAS) 1_DELHI, U y T1. Durante el estudio se caracterizaron asimismo los espoligotipos de dos M. tuberculosis aislados previamente a partir de un antílope (Antilope cervipara) y una gacela (Gazella bennettii) de Gujarat, lo que permitió adscribirlos respectivamente a los linajes EAI3_IND y EAI5. Los autores exponen la importancia desde el punto de vista epidemiológico que tiene la presencia comprobada en la región del mismo espoligotipo o de dos espoligotipos diferentes en distintas especies de la familia Bovidae, así como en el ser humano, y las consecuencias que de ahí se siguen por lo que respecta a posibles zoonosis.

Melting, crystallization and storage stability of virgin coconut oil and its blends by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR).

The blends were prepared of virgin coconut oil with refined soyabean oil (VCO-RSOY) and refined safflower oil (VCO-RSAFF). Blending with VCO improved the fatty acid composition which increased the shelf stability of 20:80 VCO-RSOY and VCO-RSAFF up to 12 months in different packaging systems such as low density polyethylene, linear low density polyethylene, metalized polyester pouches, polyethylene teteraphthalate, high density polyethylene (HDPE), Amber HDPE bottle. The specific spectral regions of FTIR proved to be very useful for the determination of adulteration as well as for the study of oxidation process. Band shifts observed at 3008, 1652, 1397, 1097, 912 and 845 cm-1 have been used to differentiate RSAFF from VCO. VCO spectrums did not have these chemical shifts. Further the spectrum of RSOY showed same band shifts as RSAFF except 1652, 1397, 869.6 and 845 cm-1. Differential Scanning Calorimetry provided useful information regarding the nature of thermodynamic changes related to physical state of vegetable oil. The physical state changes included melting and crystallization events which require the intake and release of energy.

Optimization of barrel temperature and kidney bean flour percentage based on various physical properties of extruded snacks.

The aim of the experiment was to optimize barrel temperature (122 to 178 ± 0.5 °C) and red kidney bean flour percentage (KBF) (12 to 68 ± 0.5 %) based on physical properties of extrudates like flash off percentage, water absorption index (WAI), water solubility index (WSI), bulk density (BD), radial expansion ratio (RER) and overall acceptability (OAA) using single screw extruder. The study was carried out by central composite rotatable design (CCRD) using Response surface methodology (RSM) and moisture content of feed was kept as constant 16.0 ± 0.5 % throughout experiments. Mathematical models for various responses were found to fit significantly (P < 0.05) for prediction. Optimization of experimental conditions was carried out using numerical optimization technique and the optimum barrel temperature and kidney bean flour percentage were 120 °C (T1) & 142.62 °C (T2 = T3) and 20 % respectively with desirability value of 0.909. Experiments were carried out using predicted values and verified using t-test and coefficient of variation percentage. Extruded snack prepared with rice flour (80 %) and kidney bean flour (20 %) at optimized conditions was accepted by the taste panellists and above 20 % KB incorporation was found to decrease overall acceptability score.

Effect of spinach powder on physico-chemical, rheological, nutritional and sensory characteristics of chapati premixes.

Effect of spinach powder on the physico-chemical, rheological, nutritional and sensory characteristics on chapati premixes was studied by incorporating spinach powder at different concentrations from 1 % to 10 % based on wheat flour. Addition of 5 % of spinach powder to wheat flour was found to be optimum for chapati preparation. Effect of incorporation of spinach powder on the alveo-consistographic, mixographic and pasting characteristics were studied. It was observed that peak viscosity, breakdown viscosity significantly decreases whereas, peak time, tenacity increases with the increase in the concentration of spinach powder from 1 % to 10 % in chapati premixes. Addition of spinach powder also significantly affects the textural qualities of the chapaties. Premixes and prepared chapaties were also studied for chlorophyll content, total carotenoids,vitamins and minerals.

Development of multigrain premixes-its effect on rheological, textural and micro-structural characteristics of dough and quality of biscuits.

Four different Multigrain Premixes (MGPs) namely MGP I, MGP II, MGP III, MGP IV were developed to select the best premix for preparation of biscuits based on nutritional value and biscuit quality. The MGPs were prepared using cereals (barley, sorghum, maize, oats), pulses (chickpea dhal, green gram, peas, soya flour), millets (pearl millet, finger millet) and wheat germ each at 20 % level. The MGPs developed had 22.91-27.84 % protein, 16.82-18.72 % dietary fiber and 3.11-3.46 % minerals. The wheat flour was replaced with MGPs separately at different levels of 10, 20, 30, 40 and 50 %. The incorporation of these MGPs significantly (p ≤ 0.05) decreased the water absorption (56.0-50.9 %), peak viscosity (273.67-154.92 RVU), biscuit spread ratio (10.28-8.15) and increased the pasting temperature (67.10-79.20 °C), dough hardness (311.66-460.26 N) and biscuit breaking strength (13.25-28.68 N). SEM studies showed that incorporation of MGP disrupted the protein matrix. Among the MGPs, MGP III was found to be more suitable even at the 40 % level for obtaining nutritious multigrain biscuits with higher protein, dietary fiber, and mineral content.

Comparison of stabilisers for development of a lyophilised multiplex reverse-transcription PCR mixture for rapid detection of foot and mouth disease virus serotypes.

Multiplex reverse-transcription polymerase chain reaction (mRT-PCR) assay is a sensitive and rapid method for the detection and serotyping of foot and mouth disease virus (FMDV). However, the method has not been used to its full potential, because of factors such as cost, a lack of infrastructure and the complexity of the reaction mixture. This study was undertaken to optimise and validate a thermostable, lyophilised, ready-to-use mRT-PCR kit for the rapid detection of FMDV in field laboratories in India. Trehalose, PEG-8000 and glycerol were evaluated for stabilisation of the PCR mixture at ambient temperatures. The lyophilised mRT-PCR kit was validated and found robust enough for use in field-level laboratories. The PCR reaction mixture in the ready-to-use kit has low complexity, so chances of cross-contamination during the preparation of the mixture are limited, but may easily be monitored by using lyophilised internal positive and negative controls. In addition, the requirement to maintain live FMDV isolates as internal positive controls at field-level regional laboratories is eliminated.

Comparison of efficacy of ultrasound-guided platelet rich plasma injection versus dry needling in lateral epicondylitis-a randomised controlled trial.

PURPOSE: To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS: This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS: There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION: Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

Deciphering the genetic landscape of lumpy skin disease: Unraveling variable virulence through comprehensive genome sequence analysis in India.

Lumpy Skin Disease (LSD), a poxvirus disease affecting cattle, emerged in India in 2019 and intensified in 2022, resulting in significant economic losses for dairy farmers. There was unusual shift in mortality and morbidity patterns during the second wave. A comprehensive genetic study conducted, analyzing samples from 2019 to 2022 revealed circulation of two distinct subclades (subclade 1.2a and 1.2b) in India, with the latter showing a different pattern in morbidity and mortality. Notably, the Ankyrin repeats gene-based analysis could differentiate animals with varying clinical scores. Genetic variations were significant, with unique deletions identified, including a 12-nucleotide deletion in the GPCR gene in virus isolates collected during 2022 outbreaks, not reported earlier in Indian LSDV strains. A crucial finding was a significant 95-nucleotide deletion in the Functional Resolution Sequence (FRS) repeats of LSDV genomes from 2022 outbreaks, absent in 2019 samples. These deletions may have influenced the virus's virulence in India.

Kiloh-Nevin syndrome: an unusual cause of forearm pain.

The popularity of weight training, bodybuilding and general physical conditioning has led to an increased rate of musculoskeletal injuries, such as nerve compression caused by muscle hypertrophy and, stretching of nerves peripherally. We present a case of anterior interosseous nerve (AIN) entrapment syndrome/neuropathy otherwise known as Kiloh-Nevin syndrome in a 22-year-old weightlifter. Knowledge of this injury is paramount for practitioners to increase awareness among athletes and bodybuilders.

Seroprevalence to common infectious abortifacient and infertility causing agents in the dairy herds of India.

Background: Information on the prevalence of infectious agents in dairy farms forms the basis for formulating a suitable control strategy; especially in endemic situations. Aims: A cross-sectional study was undertaken to determine the prevalence of six economically important bovine diseases, causing reproductive disorders including bovine abortion in organized dairy herds in India. Methods: A total of 1,075 animals (cattle and buffaloes) from 09 dairy farms were screened by ELISA tests. Results: Bovine viral diarrhoea (BVD) was the most prevalent (56.5%) disease followed by infectious bovine rhinotracheitis (IBR) (45.4%). Prevalence of Q-fever (5.4%) and neosporosis (6.1%) were less on the farms. Although 16.3% of the samples turned positive for brucellosis, the contribution of calf-hood vaccination (B. abortus S19 vaccine) to the prevalence of antibodies cannot be ruled out. The overall prevalence of bovine anaplasmosis, known to cause sporadic abortions in dairy herds, was 34.1% in the 9 farms with a prevalence of less than 20% in 5 farms. Infection of multiple abortifacient (seroprevalence to more than two pathogens) was recorded in 56.8% of animals. A very strong association was observed between BVD and brucellosis (Odds ratio 14.2; P<0.001). Further, a positive association was also seen between seroprevalence of IBR and anaplasmosis, and neosporosis and Q fever (P<0.05). Conclusion: Viral diseases were found to be more common in the dairy herds than bacterial and protozoan diseases. Increased susceptibility of IBR seropositive cows to other bacterial and viral infections was observed.

Natural infection of Delta mutant of SARS-CoV-2 in Asiatic lions of India.

The current pandemic caused by a novel coronavirus (SARS-CoV-2) has underlined the importance of emerging diseases of zoonotic importance. Along with human beings, several species of wild and pet animals have been demonstrated to be infected by SARS-CoV-2, both naturally and experimentally. In addition, with constant emergence of new variants, the species susceptibility might further change which warrants intensified screening efforts. India is a vast and second most populated country, with a habitat of a very diverse range of animal species. In this study we place on record of SARS-CoV-2 infections in three captive Asiatic lions. Detailed genomic characterization revealed involvement of Delta mutant (Pango lineage B.1.617.2) of SARS-CoV-2 at two different locations. Interestingly, no other feline species enclosed in the zoo/park were found infected. The epidemiological and molecular analysis will contribute to the understanding of the emerging mutants of SARS-CoV-2 in wild and domestic animals.

Palladium urchin-like nanostructures and their H2 sorption properties.

Urchin-like palladium nanostructures were synthesized by slow radiolytic reduction of Pd(II) in cetylpyridinium chloride (CPCl) micellar solution. They were formed by polycrystalline nanowires originating from the same core. The growth process leading to these urchin-like structures has been studied. These three-dimensional (3D) nanostructures were obtained at high Pd concentration (0.1 M) which led to a relatively large quantity of nanomaterials. These nanostructures show very interesting cycling sorption properties for hydrogen storage.

Influence of cooking methods on antinutritional factors, oligosaccharides and protein quality of underutilized legume Macrotyloma uniflorum.

Macrotyloma uniflorum is a salubrious but underutilized legume mainly consumed in semi-arid zones of Africa, Australia and India. Various antinutritional factors- phytates, oxalates and oligosaccharides- has limited its consumption. Current work describes the influence of various thermal processing technologies - autoclaving, microwave, micronization and extrusion- on antinutritional profile, phenolic acid profile and protein digestibility of two selected varieties. Significant (p ≤ 0.05) reduction in antinutritional content was observed for horse gram grains processed using various thermal technologies. Among all processing technologies extrusion caused marked degradation in antinutritional components. The reduction in oxalic acid, trypsin inhibitor, phytates and tannins ranged from 33 to 87 %, 77-82%, 33-60% and 51-66% respectively. Further, the decline in content of various oligosaccharides viz. raffinose, stachyose and verbascose varied from 36 to 61 %, 25-49% and 30-74% respectively for both the varieties. Although extrusion caused significant (p ≤ 0.05) decrease in the essential amino acid index and protein efficiency ratio, simultaneous increased was observed in biological value. The processing had significant (p ≤ 0.05) impact on grain antinutritional content and also retained its substantial functional properties. This establishes the utility of grain and promote the introduction of these new grains and enlarge the market of novel healthy foods.

Isolation and genetic characterization of canine adenovirus type 2 from a domestic dog showing neurological symptoms.

Canine adenoviruses (CAVs) are of two types: canine adenovirus type 1 (CAV-1), which causes infectious canine hepatitis, and canine adenovirus type 2 (CAV-2), which is mainly associated with the respiratory type of disease in dogs. Due to the widespread use of modified live vaccines to control canine adenoviral infections and subsequently reduced disease incidence, CAVs are often neglected by clinicians. Although a number of studies are available about CAV-1 prevalence in India, only meagre information is available about CAV-2. This study reports the CAV-2 infection in a vaccinated dog with neurological and respiratory symptoms which was found negative for other canine pathogens like canine distemper virus and canine parvovirus. The virus was successfully isolated from rectal swab in MDCK cells and characterized by immunofluorescence assay and virus neutralization test. On phylogenetic analysis of partial E3 region, the Indian CAV-2 grouped in a separate clade different from established subgroups. An insertion of "G" nucleotide was reported at nucleotide (nt.) position 1077 in the E3 gene of Indian CAV-2 isolates which led to a frameshift in the coding region of E3 gene thereby imparting additional eleven amino acids to its C-terminal end in comparison to isolates from other parts of the world. This may have an implication on the functional role of E3 protein inside the cell. This study reinforces the unique signature insertion in the E3 gene of Indian CAV-2 and is the second study in the world to report the association of CAV-2 with neurological disease in dogs.
