Antibacterial activity of Khaya senegalensis stem bark extracts against some bacteria isolated from poultry droppings

Recent findings have incriminated the use of antibiotics in poultry feeds to be associated with emergence of resistance among bacteria. The use of traditional plants remedies has not been found to be associated with resistance. This work determined the inhibitory effects of extract of Khaya senegalensis used in traditional poultry farming against Salmonella species, Escherichia coli, Proteus species, Pseudomonas species and Staphylococcus aureus isolated from poultry dropping. The method of maceration was adopted to extract the plant materials with methanol (70%) and sterile water as solvents for the extraction. One gram each of sample (poultry dropping) was diluted in selenite F broth and another one gram each was inoculated directly into Salmonella – shigella agar, blue green agar, McConkey agar, Manitol salt agar and Eosin methylene blue agar (EMB). After an overnight incubation at 37oC for 24 hrs plates were read. Typical colonies were grams Stained using Standard procedures, consequent upon that, the isolated gram negative organisms were subjected to biochemical test. The only Gram positive organism isolated was further confirmed to be S. aureus by catalase and coagulase tests. Bioassay of the isolates was conducted and further Subjected to the plant extracts, using agar well diffusion method and conventional antibiotics using disc diffusion (Kirby bouer). Findings shows significant effect of the plant extracts on the isolated bacteria and also indicated that it can serve as an alternative to conventional antibiotics as used in traditional poultry production in Nigeria. This practice can also go a long way in minimizing Emergence of resistance strains of bacteria in human diseases since drugs derived from plants are safe and dependable, compared to synthetic drugs.
Mechanisms of removal of injected microorganisms from the American oyster, Crassostrea virginica (Gmelin).

1. The fate of injected bacterial spores, vegetative bacteria and yeast cells injected into the oyster, Crassostrea virginica, was followed histologically and by viability studies.2. Tissue sections showed that yeast cells were phagocytized in blood vessels by leukocytes which migrate into surrounding tissues and later through epithelial layers to the exterior. A small proportion of yeast cells remaining in the tissues are digested intracellularly.3. Histologic examination of oysters injected with living bacteria revealed that the microorganisms were rapidly destroyed both intracellularly and extracellularly before significant numbers of host phagocytes could migrate to the exterior.4. Viability experiments demonstrated that when several species of non-spore-forming bacteria were injected, very few of these organisms could be recovered 48 hours later. However, a small proportion of these bacteria persisted in oyster tissues for several days.5. Bacterial spores were removed from oyster tissues at a much sl.
When schools reopen, don’t neglect recess

When schools reopen in the fall, students and adults will return carrying stress and trauma arising from the sudden school closings, the social isolation, and the illness and unrest that many experienced over the summer. Rebecca London urges elementary school leaders to attend to students’ mental health and emotional needs by offering recess time every day. The need for play will be especially great among students of color and students in low-income areas, many of whom had insufficient recess time in school before the pandemic.
Synthesis of heat-shock proteins HSP-70 and HSP-90 in flowers of common buckwheat (Fagopyrum esculentum) under thermal stress

Abstract. Common buckwheat (Fagopyrum esculentum Moench) is a valuable crop plant with cereal-like seed chemical composition; however, it is susceptible to thermal stress. The aim of the study was to determine whether heat-shock proteins HSP-90 and HSP-70 can protect common buckwheat against thermal stress during development of microspores and embryo sacs. The study was performed on two accessions of common buckwheat, Panda and PA15, which differed in their tolerance to thermal stress. Accumulation of these proteins was determined in buds, open and wilted flowers, and donor leaves of plants grown at 20°C (control) and 30°C (thermal stress). Photochemical efficiency of donor leaves, closest to the inflorescences, based on chlorophyll a fluorescence (ChlF) was also analysed. All plants demonstrated higher values of ChlF at 30°C than at 20°C, which suggests that this 30°C temperature is more conducive to their vegetative growth. Pollen grains of both accessions demonstrated normal development at 30°C, whereas embryo sacs showed many developmental disturbances. Panda was more sensitive to thermal stress than PA15, as manifested in a higher percentage of degenerated embryo sacs at the flower bud phase. Moreover, a decrease in both HSPs in the studied organs of Panda was found relative to the control. At 30°C, both accessions accumulated more HSP-70 than HSP-90. These results suggest that, under heat stress, HSP-70 plays a protective role for flowers of common buckwheat. The analyses indicated that the donor leaf closest to the flower cluster may be a reliable indicator of temperature sensitivity in buckwheat flowers.
Pedal grasping in the northern smooth-tailed treeshrew Dendrogale murina (Tupaiidae, Scandentia): insights for euarchontan pedal evolution

Abstract Pedal grasping evolution in euarchontan mammals is of great importance as it bears on the adaptive significance of specialized hallucal grasping and arboreal niche use related to the group differentiation. Basally divergent arboreal tupaiid treeshrews are very suitable for testing pedal grasping modes and associated substrate correlates and provide insights on euarchontan pedal evolution. For these purposes we filmed wild-caught Dendrogale murina from Vietnam and analyzed their foot mechanisms. Our observations showed that hallucal grasp was moderately used and was mainly associated with small and horizontal substrates. Convergent grasp was frequently used on medium-sized and horizontal substrates whereas claws were related to large and vertical substrates. In addition, the foot was frequently inverted and mainly placed in a semiplantigrade position. Inversion and semiplantigrady dominated on small, medium-sized and horizontal substrates but decreased on larger substrates with increased inclinations. The observed pedal mechanism probably represents a derived condition, where hallucal grasping tends to become slightly restrained, compared to the primitive euarchontan (and scandentian) pedal grasping mechanism. Furthermore, it hallmarks an early stage in tupaiid evolution towards a more constrained pedal grasping. This further substantiates pedal grasping plasticity within euarchontan mammals and highlights the strong relation between a hallucal grasping mechanism and the frequent and primary use of small slender substrates.

Based on a deep understanding of the importance and connotation of the sustainable development of marine ecosystem, this paper introduces the information entropy theory, combines the entropy change analysis and information entropy effectively, analyzes and evaluates the development and evolution of China's marine ecosystem and its sustainable development ability, and puts forward the sustainable development countermeasures, providing scientific basis for the sustainable development of China's marine ecosystem.
Microhardness of fiberglass – reinforced photocomposite material under different conditions of light polimerization

The aim : to study in laboratory conditions the microhardness of a glass-fiber-reinforced photocomposite under different modes of light exposure at different times. Materials and methods . The microhardness of the everX Posterior, GC glass-fiber-reinforced photocomposite was investigated on 60 samples using a PMT-3 microhardness meter on three sample surfaces within 1 hour, 1 day and 7 days after polymerization. Samples of a cylindrical shape with a height of 3 mm of group 1 were irradiated with the light flux of a photopolymerizer in the "soft start" mode, samples of group 2 were polymerized with light of constant high intensity 1400 mW/cm 2 . Research results . After 1 hour, the microhardness on the surface closest to the LED was 87.34±1.21 kgf/mm 2 in samples of group 1, 102.0±0.94 kgf/mm 2 (p<0.05) in group 2, and 70.98±1.23 kgf/mm 2 (the lowest indicator) and 90.65±1.12 kgf/mm 2 (p<0.05). After 1 day, on the nearest surface, the microhardness increased in the samples of group 1 to 97.03±1.25 kgf/mm 2 , group 2 – to 114.61±1.13 kgf/mm 2 (p<0.05), on the most distant - up to 75.95±1.11 kgf/mm 2 and 99.83±1.24 kgf/mm 2 (p<0.05), respectively. At 7 days, the indicators on the first surface in group 1 were 104.64±1.23 kgf/mm 2 , in 2 – 123.35±1.15 kgf/mm 2 (p<0.05), on the other surface – 80.25±1.48 kgf/mm 2 and 107.53±0.92 kgf/mm 2 (p<0.05). The growth of microhardness on these surfaces for the entire period was 16.5 % and 11.6 % in the samples of group 1, and 17.3 % and 15.7 % in group 2. Conclusions. The light flux of constant high intensity provides statistically significantly (p <0.05) higher microhardness indices of the glass-fiber reinforced photocomposite on all surfaces of the samples than the light exposure in the “soft start” mode. In the direct restoration of teeth, it is necessary to reduce the thickness of the photocomposite layer for "soft start" polymerization
On Implementing an Albedo Solution with Urban Heat Islands Global Warming and Cooling Estimates

Solar geoengineering is vital in global warming as results can reverse trends and reduce the probability of a tipping point. As well, the pace and depth of implementing the Greenhouse Gas (GHG) solution is tenuous. This paper focuses on the implementation of a surface solar geoengineering solution to global warming. Although an albedo solution is reasonably practical, work in this area appears stagnant and even implementing Urban Heat Island (UHI) cool roofs on a global level has not yet been widely adopted. Often, to the contrary, urbanization and road construction selection of high solar-absorbing materials continues to be the norm. The solar solution is incorrectly overlooked by comparison to GHG mitigation. This paper provides basic modeling and motivation in our UHI assessments by illustrating the potential impact for reverse forcing. We provide insights into “Earthly components” that can be utilized to increase the opportunity for reducing climate change. Modeling shows that by solar geoengineering hotspots such as UHIs, the effective area could be roughly 11 times smaller than nominal non-hotspot regions in influencing global warming. Indications suggest the corrective action area sizes are of the order of UHI coverage. The versatile model presented, also shows significant global warming estimates due to UHIs and their coverage.
Treatment of Cancer by Using Sea Cucumber

Sea cucumbers and their extracts have gained immense popularity and interest among researchers and nutritionists due to their nutritive value, potential health benefits, and use in the treatment of chronic inflammatory diseases. Many areas of the world use sea cucumbers in traditional foods and folk medicine. Though the actual 6vcomponents and their specific functions still remain to be investigated, most sea cucumber extracts are being studied for their anti-inflammatory functions, immune stimulatory properties, and for cancer prevention and treatment. There is large scope for the discovery of additional bioactive, valuable compounds from this natural source. Sea cucumber extracts contain unique components, such as modified triterpene glycosides, sulfated polysaccharides,glycosphingolipids, and esterified phospholipids. Frondanol A5, an isopropyl alcohol/water extract of the enzymatically hydrolyzed epithelia of the edible North Atlantic sea cucumber, Cucumaria frondosa, contains mono sulfated triterpenoid glycoside Frondoside A, the disulfated glycoside Frondoside B, the trisulfated glycoside Frondoside C, 12-methyltetradecanoic acid, eicosapentaenoic acid, and fucosylated chondroitin sulfate. We have extensively studied the efficacy of this extract in preventing colon cancer in rodent models. In this review, we discuss the anti-inflammatory, immune stimulatory, and anti-tumor properties of sea cucumber extracts.
KINETIC AND SEX-BASED ANALYSIS OF THE TRADITIONAL AND HORIZONTAL HANG CLEAN

The horizontal hang clean (H-HC) is a novel variation of the traditional hang clean (T-HC). This study evaluated the H-HC and T-HC and compared the horizontal and vertical ground reaction forces and the ratio of those forces (H:V), to the horizontal and vertical ground reaction forces and H:V of the countermovement jump (CMJ) and standing sprint start (SSS). Ten men and ten women NCAA Division III athletes performed the T-HC, H-HC, CMJ, and SSS on a force platform. Results revealed that the H-HC produced a significantly (p ≤ 0.001) greater H:V than the T-HC. There was no interaction between any of these variables and sex (p > 0.05). The H-HC should be included in training programs of men and women to increase the likelihood of transfer of training to activities such as sprinting.

THE EFFECT OF REPRESENTATIVE TASK DESIGN ON GROUND REACTION FORCES PRODUCED BY ADOLESCENT RUGBY PLAYERS

Our primary aim in this study was to investigate differences in the ground reaction forces (GRFs) produced when adolescent rugby players performed match-reflective tasks of increasing degrees of representativeness. Fourteen male players performed three tasks; a straight jog, an anticipated cut and an unanticipated cut. These tasks were performed in four different conditions; landing with their dominant or non-dominant leg, while carrying or not carrying a rugby ball. Greater GRFs were recorded during both the weight acceptance and late push-off phases of the cutting tasks compared with the straight jog and during the push-off phase when the direction of the cut was anticipated. Carrying a ball, however, did not affect the GRFs recorded. These findings highlight the importance of employing representative task design when assessing performance and designing practice.

The serial correlations of illiquid stock's price movements are studied, by taking into account for the effect of the stochastic zero returns in various situations. More precisely, heteroscedasticity and time-varying zero returns probability patterns are considered. Depending on the set up, we investigate how the usual autocorrelations can be accommodated, to deliver an accurate representation of the price changes serial correlations. An index and a cumulative sum (CUMSUM) test for choosing the adequate tool are provided. We shed some light on the properties of the different serial correlations measures, by mean of Monte Carlo experiments. The theoretical arguments are illustrated considering shares from the Chilean stock market.
From the Sun to Earth: effects of the 25 August 2018 geomagnetic storm

Abstract. On 25 August 2018 the interplanetary counterpart of the 20 August 2018 coronal mass ejection (CME) hit Earth, giving rise to a strong G3 geomagnetic storm. We present a description of the whole sequence of events from the Sun to the ground as well as a detailed analysis of the observed effects on Earth's environment by using a multi-instrumental approach. We studied the ICME (interplanetary-CME) propagation in interplanetary space up to the analysis of its effects in the magnetosphere, ionosphere and at ground level. To accomplish this task, we used ground- and space-collected data, including data from CSES (China Seismo-Electric Satellite), launched on 11 February 2018. We found a direct connection between the ICME impact point on the magnetopause and the pattern of Earth's auroral electrojets. Using the Tsyganenko TS04 model prevision, we were able to correctly identify the principal magnetospheric current system activating during the different phases of the geomagnetic storm. Moreover, we analysed the space weather effects associated with the 25 August 2018 solar event in terms of the evaluation of geomagnetically induced currents (GICs) and identification of possible GPS (Global Positioning System) losses of lock. We found that, despite the strong geomagnetic storm, no loss of lock had been detected. On the contrary, the GIC hazard was found to be potentially more dangerous than other past, more powerful solar events, such as the 2015 St Patrick's Day geomagnetic storm, especially at latitudes higher than 60∘ in the European sector.
Stability Analysis for Seed Yield and Related Component Traits of Ethiopian Mustard Genotypes (Brasica Carinata A.Braun ) in Central Highlands of Ethiopia

Ethiopian mustard (Brassica carinata A.Braun) is believed to be originated in the highlands of the Ethiopian plateau and the adjoining portion of East Africa and the Mediterranean coast (Gomez-Campo and Prakash, 1999). In Ethiopia, among the highland oilseeds, Ethiopian mustard stands third next to niger seed and linseed in total production and areas coverage. It is often grown on well-drained and organic matter rich soils. The crop is well adapted to cool, long growing season and high rainfall areas at elevation between 2200 and 2800 meters. It is because of its wider adaptability and comparative tolerance to biotic and abiotic stresses as compared to other Brassica species grown as oilseeds. However, production of Ethiopian mustard is far below the national average. Under such a situation, it becomes very important to identify genotypes which can show a stable performance over different environments or locations. The genotype x environment interaction as described by the Allard and Bradshaw in 1964 is very important in the development and evaluation of genotypes, since diverse environments can reduce the stability of genotypes (Eberhart and Russell, 1966). The stability is the consistency in performance of genotypes over wide range of environment (Singh and Chaudhary, 1985). Only stable genotypes can guarantee a good yield with decreased risk of losing production and allow the plant breeders to make general recommendations for a range of environments. Keeping these facts in to consideration, the present investigation was carried out by considering nine Ethiopian mustard genotypes comprising one standard and local check to test stability over the three environments of central highlands of Ethiopia.
