Studies on detection and antibiotic sensitivity and resistance pattern of Listeria monocytogenes isolated from cattle, raw cow milk and milk products from Tripura, India

A total 200 numbers of samples including cattle faeces (50), raw milk (50) and milk products (100) were collected randomly to study the occurrence and antibiotic sensitivity of L. monocytogenes from West Tripura district, Tripura. The L. monocytogenes was isolated by using two step enrichment method of culturing and identified based on cultural characteristics, gram staining, biochemical properties, tumbling motility and in vitro pathogenicity tests. The antibiotic sensitivity was studied against 12 numbers of commonly used antibiotics in animals and human. The occurrence of L. monocytogenes was recorded as 8.50 percent including 6.00 percent (3/50) from cattle faeces, 8.00 percent (4/50) from raw milk, 12.00 percent (3/25) from lassi, 16.00 percent (4/25) from dahi and 12.00 percent (3/25) in ice-cream. The L. monocytogenes strains showed 100 percent sensitivity towards Penicillin, Ampicillin, Oxacillin, Cephotaxime /Clavulanic acid, Ciprofloxacin, Tetracycline and Trimethoprim/Sulphamethoxazole followed by Streptomycin (88.23%), Chloramphenicol (82.35%), Gentamicin (70.58%) and Ceftriaxone (52.94%). The presence of the organism in milk and milk products indicates unhygienic handling during production, processing and marketing is an alarming public health threat to the consumers.
Noccaea birolmutlui , a New Crucifer Species from South West Anatolia, Turkey

Noccaea birolmutlui Ozgisi & Ozudogru is described as a new species from Kizildag National Park, Isparta, in SW Anatolia. It resembles N. ochroleuca but can be readily distinguished by several morphological characters including shape and size of basal/stem leaves, fruit shape, style length, ovule number etc. Nuclear-encoded ribosomal internal transcribed spacer (ITS) region based phylogeny proved that this species clearly differs than N. ochroleuca and these two species belong to different clades in Noccaea s.str. Diagnostic characters, a description, detailed photos and taxonomic comments on the species are given. Morphological affinities and ITS based phylogenetic relationships of new species are discussed. Furthermore, the IUCN Red List category of N. birolmutlui is proposed as critically endangered (CR) due to its limited distribution.
Modelling of Heat Transfer and Fluid Flow through a Granular Material and External Wall Barrier

Heat and fluid flow simulations for granular material in wall barriers allow to design them in a way that maximally reduces the expenditures on utilisation of buildings. This paper demonstrates the solution to the problem of the passage of air through the external wall barrier. It shows how the temperature changes inside the wall barriers when the external temperature changes. Two types of partitions are tested: single-layer (granular material) and two-layer (granular and concrete material). The paper presents comparison of the results of the numerical model and in-house code with the experimental data. The numerical model applied is based on the unsteady equation of heat conduction (3D) and the Navier-Stokes equations. A high-order compact method in combination with the WENO scheme and predictor-corrector method are applied for the spatio-temporal discretisation. The flows of air and heat in the granular layers are modelled using immersed boundary technique, which allows to use Cartesian meshes for objects with very complex geometric shapes. The correctness of numerical model applied has been verified by comparisons with ANSYS Fluent results and experimental data obtained from measurements performed in a laboratory and in-situ.
ON THE NORM OF A MULTIDIMENSIONAL HILBERT-TYPE OPERATOR

In this paper we consider multidimensional Hilbert-type integral inequalities with non-conjugate exponents and homogeneous kernels of negative degree. As an application, we define related Hilbert-type integral operators and consider their norms. The problem of determining the norm of such operators is equivalent to the problem of the best possible constant factors involved in the right-hand sides of related inequalities. In such a way, we obtain the norms and the best possible constant factors in some general settings with conjugate exponents. In particular, we obtain generalizations of some recent results from the literature.
Gut microbiome in liver disease

A diverse community of microbes resides in the human intestine to maintain the homeostasis of metabolic status and immune response in the host. Dysbiosis of intestinal flora was noted in a wide range of disease, including obesity, autoimmune diseases, diabetes, carcinogenesis and liver diseases. Here we review the current knowledge of the gut flora under liver pathogenesis, including non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-induced liver disease and hepatitis B virus (HBV)-induced liver cirrhosis. Liver malfunction leads to heavily altered genetic composition of gut microbial, while distinct bacterial species are present during liver pathogenesis, and the abundance of bacteria is correlated with grade of liver disease, suggesting the key role of “gut-liver axis”. Further, we also discuss the high throughput sequencing technology with status of art as well as the future challenges in this emerging field of gut microbiome.
Physicochemical and nutraceutical characterization of sirimbache fruit (Gaultheria glomerata (Cav.) Sleumer)

The consumption of vegetables with the greatest nutraceutical potential, especially those with high levels of antioxidants such as anthocyanin and phenolic compounds, has become popular among health conscious consumers. The aim of this research was to determine the nutraceutical potential of sirimbache fruits ( Gaultheria glomerata (Cav.) Sleumer). Characterization of the berries resulted in the following: 11.4 °Brix, 3.25 pH, 0.35% acidity, 83.74% moisture, 0.16% ash, monomeric anthocyanins (112.88 mg cyanidin 3-glucoside / 100 g of sample), total phenolic compounds (344.37 mg of gallic acid / 100 g of sample) and vitamin C (13.87 mg ascorbic acid/ 100 g of sample). These values indicate that sirimbache is a nutraceutical food of great interest. Therefore, the expansion of sirimbache to health conscious markets may be feasible. Such expansion is of great importance for rural agribusiness, as it could promote the development of new agroindustrial projects in the province of Celendin and other Andean areas of Peru.
Prophylactic effects of Nigella sativa extract and thymoquinone against cyclophosphamide-induced sperm head abnormalities and chromatin instability in mice

Genetic stability in male fertility is indicated by DNA integrity of sperm. Cyclophosphamide is cytotoxic to germ cells of the testes causing DNA breakage, azoospermia and infertility. This study focuses on effectiveness of Nigella sativa and thymoquinone in lowering chemotherapeutic-associated toxicity of cyclophosphamide on sperm head and chromatin stability of Balb/c mice. Thirty male mice were divided into 6 groups and administration of cyclophosphamide at 200 mg/kg body weight by intraperitoneal injections is followed similarly by either thymoquinone or ethanol extraction of Nigella sativa at 10 mg/kg, 6 hours post cyclophosphamide exposure. Thymoquinone and Nigella sativa administration was continued on alternate days for 32 days. Sperm samples were assayed with Eosin Y and Toluidine Blue. Sperm head abnormalities were classified into normal, lack-hook, banana-like form, amorphous and folded on themselves. Chromatin condensation was categorised into unstained, completely and partially-stained. One hundred spermatozoa per animal were observed. Nigella sativa extract reduced the percentage of abnormal sperm head post-cyclophosphamide treatment and showed preservation of the normal chromatin condensation indicative of protection against sperm DNA alteration. This study indicates the potential of Nigella sativa and thymoquinone as prophylaxes against cyclophosphamide-induced damage to gametes in the attempt to salvage reproductive functions following chemotherapy.
Role of Vitamin D Supplementation in Heart Failure Patients With Vitamin D Deficiency and Its Effects on Clinical Outcomes: A Literature Review

Vitamin D deficiency has become a global pandemic affecting approximately one billion people worldwide. Much attention has been paid to the association of low serum 25-hydroxyvitamin D (25(OH)D) levels and various chronic diseases, especially heart failure (HF). A clear role of vitamin D deficiency has been established, with increased mortality and morbidity in heart failures. However, previous randomized control trials have failed to show improvement in clinical outcomes with calciferol supplementation in these patients. Therefore, it is still unclear whether calciferol therapy can be added to the standard care in congestive heart failure (CHF) patients with deficiency. Hence, to evaluate the role of vitamin D supplementation in CHF patients with low serum 25(OH)D, we conducted an extensive search in the PubMed and Google Scholar databases using various combinations of keywords. All potentially eligible studies that evaluated the effects of vitamin D supplementation on clinical outcomes in HF patients were retrieved and extensively studied. We also checked the references of all eligible studies to identify additional relevant publications. In this study, we reviewed various mechanisms of vitamin D affecting the cardiovascular system and examined the impact of deficiency on heart failures in terms of mortality and hospitalizations. In conclusion, vitamin D supplementation has failed to improve the clinical outcomes in HF patients. The possible long-term benefits of supplementation cannot be excluded. Therefore, for future clinical trials, we recommend considering large sample sizes, longer follow-up durations, along with optimal dosage and appropriate dosing frequency.
A MULTI-TYPE RAY-KNIGHT THEOREM

The Ray-Knight theorem describes the path behavior in the spacial variable of the local time of a Brownian motion stopped at appropriate times and the resulting process is a continuous state branching process. We show that under appropriate assumptions, a multi-type branching process with immigration can be obtained as the local times of a system of stochastic processes. These assumptions are easily seen to be met in the Brownian setting, and more generally an α-stable setting for α ∈ (1, 2]. Using these processes, we also extend the Gorin-Shkolnikov identity [18] to certain random fields.
An explanation to the Nusselt-Rayleigh discrepancy in naturally convected porous media

We model hydrothermal convection using a partial differential equation formed by Darcy velocity and temperature the velocity formulation. Using the Elder problem as a benchmark, we found that the velocity formulation is a valid model of hydrothermal convection. By performing simulations with Rayleigh numbers in the non-oscillatory regime, we show that multiple quasi-steady-state solutions can be one of the reasons that caused the Nusselt-Rayleigh discrepancy found in previous experiments. The results reveal more understandings about the nature of uncertainty of convection modes in porous media.

Oxidative status in nestlings shows different associations with parental carotenoid-based plumage ornaments depending on parental sex and year: a study of rock sparrows Petronia petronia

Carotenoid-based colouration in birds has been suggested to be a sexually selected signal, allowing individuals to obtain reliable information about the quality of antioxidant resources. Moreover, oxidative stress levels during early development may have medium- and long-term fitness consequences. Rock sparrows (Petronia petronia) display a carotenoid-based breast patch in both sexes which has been shown to function as a signal of phenotypic quality in sexual and social interactions. We studied a rock sparrow population in central Spain aiming to test whether the extent of the carotenoid-based breast patch is associated with offspring growth and oxidative status. We have used plasma malondialdehyde (MDA) level in plasma as a measure of oxidative damage, and total antioxidant status of plasma (TAS) and total glutathione (tGSH) levels in red blood cells as measures of antioxidant defences. The study included the extremely late breeding season of 2013 and the phenologically more normal season of 2014. Unfavourable conditions for breeding resulted in smaller nestlings in 2013. Male breast patch size showed a negative association with nestling tarsus length and, strikingly, a positive association with nestling MDA. It also showed a positive relationship with nestling wing length in interaction with year. Nestlings in late and larger broods showed higher tGSH levels. Female breast patch size showed positive associations with nestling tGSH levels, indicating positive links of maternal ornamentation with offspring condition. Moreover, TAS values were only positively associated with female patch size under favourable conditions, as shown by the interaction with year. Associations of carotenoid-based parental plumage ornaments with offspring growth and oxidative status depends on parental sex and environmental conditions. Carotenoid-based plumage traits signal parental quality in female rock sparrows, while paternal ornaments seemingly do not reflect parental quality. To our knowledge, this is the first study to investigate the association between female plumage ornaments and offspring antioxidant capacity. The same signal may reflect different parental attributes in the two sexes in sexually monomorphic species.
LS-DYNA simulations of the impacts of a 38-ton Heavy Goods Vehicle into a road cable barrier

Nowadays, more and more attention is being paid to safety on roads and motorways. It is due to the continuous development of road and motorway network and a significant increase of the number of vehicles on roads. To meet the expectations of improving road safety in Poland, the Road Innovations Development (RID) research programme was implemented in 2016. The aim of the RID 3A Road Safety Equipment (RoSE) project is a comprehensive analysis of various road restraint systems and various types of road safety equipment installed on roads and bridges. The RID 3B Effect of time and operating conditions of the durability and functionality of the elements of road safety (LifeRoSE) complementary project is aimed at developing innovative and comprehensive road management methodology for road safety equipment and traffic management measures. Part of the aforementioned projects is a thorough study of safety barriers based, among others, on full-scale crash tests and a number of numerical simulations using LS-DYNA. The aim of the paper is to assess the crashworthiness of a road cable barrier during an impact of a Heavy Goods Vehicle (HGV) weighing 38 tons. A numerical model of the safety device was developed and validated with a full-scale crash test. Based on this computational model, a series of virtual crash tests were carried out in which the HGV collides with the barrier under various impact conditions. Some of the cases will be compared with real accident outcome that took place on highway in Poland.
Additive Effects of QTLs Related to Grains in Rice

Advanced backcross QTL analysis was used to identify quantitative trait loci for grain-related traits in a population derived from a cross between IR64 and Tarom Molaei. Parental survey was done by 235 SSR markers, among them 114 markers with clear polymorphic bands were employed for genotyping of 59 advanced backcross lines. Using multiple interval mapping, a total of 11 putative QTLs were detected, of which 5 were for grain length (GL), 3 for grain width (GW), 3 for grain shape (GS). Additive by additive digenic epistasis effects observed for GL and GW. The present study indicated that favorable QTL alleles from the traditional varieties of rice can be transferred into an improved rice variety by advanced backcross QTL strategy and molecular breeding.
Wetland Waterbird Food Resources Increased by Harvesting Invasive Cattails

The conservation of many freshwater marsh waterbirds (i.e., waterfowl, shorebirds, wading birds, and secretive marshbirds) in the Laurentian Great Lakes requires managing invasive emergent macrophytes, which degrade waterbird habitat by creating dense, litter‐clogged stands, and excluding plants that produce nutritionally balanced and high‐energy food (seeds, tubers, and submerged aquatic vegetation). The most commonly used management approach in the United States Great Lakes region involves the application of herbicides, which can stimulate waterbird forage plants but does not address the accumulation of plant litter, the underlying cause of plant community diversity loss and habitat degradation. We experimentally evaluated the effects of an alternative approach, harvesting invasive plants and their litter followed by flooding, on plant communities, focusing on the effects of these treatments to increase the abundance of high‐energy wetland plants. At the Shiawassee National Wildlife Refuge in Michigan, USA, we experimentally treated an invasive cattail (Typha × glauca)‐dominated wetland in August and September of 2016, 2017, and 2018, using a randomized block design with 4 blocks and 3 treatments (sediment surface harvest, above ground harvest, and control). We monitored the effects of these treatments on the abundance and dominance of waterbird forage‐producing plants, plant diversity, and plant communities prior to ( Jul 2016) and during the summer following each treatment (late Jul or early Aug 2017, 2018, and 2019). Additionally, we used pre‐ and post‐treatment waterbird use‐day data collected at the unit scale and compared values with satellite imagery‐derived land cover changes. Compared to control plots, 3 years of harvesting and flooding significantly increased plant species diversity, increased the abundance of waterbird seed‐ and tuber‐producing plant species by 5 times, and increased annual plant dominance by more than 10 times, while substantially reducing all measures of cattail and its litter. Use‐days increased for total waterbirds, including waterfowl and dabbling ducks, following treatment. Cattail cover decreased and open water and non‐cattail emergent vegetation cover increased. Harvesting invasive plant biomass coupled with flooding promoted a plant community composition and structure beneficial to waterbirds. © 2020 The Wildlife Society.
Ocotea porosa: Anatomy and Histochemistry of Leaves and Stems, Chemical Composition, Cytotoxicity and Insecticidal Activities of Essential Oil

Ocotea porosa (Nees & Mart.) Barroso, commonly known as “imbuia”, “canela-imbuia” or “imbuiaamarela” in Brazil, is a tree of the Southern Atlantic Forest. The present study investigates the anatomy of leaf and stem, volatile oil chemistry, as well as cytotoxicity and insecticidal activities of the essential oil of O. porosa. Species identification was achieved by anatomy features, mainly due to paracytic and anomocytic stomata; non-glandular trichomes; biconvex midrib and petiole with a collateral open arc vascular bundle; presence of a sclerenchymatous layer, starch grains and crystal sand in the stem; and the presence of HIGHLIGHTS  The anatomy features were useful for identification of Ocotea porosa.  The major volatile compounds were α-pinene, β-pinene and bicyclogermacrene.  Essential oil of O. porosa was cytotoxic against McCoy, B16F10 and MCF7cell lines.  The cytotoxic mechanism might be related to apoptotic events.  Insert 1-4 highlights no longer than 85 characters.  Insert a highlight no longer than 85 characters.  Insert a highlight no longer than 85 characters. • Insert a highlight no longer than 85 characters. 2 Brustulim, L.J.R, et.al. Brazilian Archives of Biology and Technology. Vol.63: e20190082, 2020 www.scielo. br/babt phenolic compounds in the epidermis, phloem and xylem of the midrib, petiole and stem. The main volatile components of the essential oil were α-pinene (19.71%), β-pinene (13.86%) and bicyclogermacrene (24.62%). Cytotoxicity against human cancer cell (MCF-7), mouse cancer cell (B16F10) and mouse nontumoral cell (McCoy) was observed as well as insecticidal activity of the essential oil against susceptible ‘Ft. Dix’ bed bugs (Cimex lectularius L.) by topical application.
Mechanical Properties of SiO2-Coated Carbon Fiber-Reinforced Mortar Composites with Different Fiber Lengths and Fiber Volume Fractions

In the present study, SiO2 particles were coated on the surface of carbon fibers by means of chemical reaction of silane coupling agent (glycidoxypropyl trimethoxysilane, GPTMS) and colloidal SiO2 sol to improve the interfacial bonding force between fibers and matrix in cement matrix. The surface of the modified carbon fibers was confirmed through a scanning electron microscope (SEM). The mechanical properties of SiO2-coated carbon fiber mortar and uncoated carbon fiber mortar with different fiber lengths (6 mm and 12 mm) and fiber volume fractions (0.5%, 1.0%, 1.5%, and 2.0%) were compared and analyzed. The experimental results show that the flow values of the carbon fiber mortar were greatly disadvantageous in terms of fluidity due to the nonhydrophilicity of fibers and fiber balls, and the unit weight decreased significantly as the fiber volume fractions increased. However, the air content increased more or less. In addition, regardless of whether the fibers were coated, the compressive strength of carbon fiber-reinforced mortar (CFRM) composite specimens tended to gradually decrease as the fiber volume fractions increased. On the other hand, in case of the SiO2-coated CFRM composite specimens, the flexural strength was significantly increased compared to uncoated CFRM composite specimens and plain mortar specimens, and the highest flexural strength was obtained at 12 mm and 1.5%, particularly. It can be seen that the new carbon fiber surface modification method employed in this study was very effective in enhancing the flexural strength as cement-reinforcing materials.
