Dynamic changes of endogenous H2S generation during responding to developmental and environmental signals in Solanum lycopersicum L.

Increasing studies have confirmed the functions of hydrogen sulfide (H2S) as a gas signal molecule (gasotransmitter) in a variety of physiological activities in plants. However, the dynamic changes of endogenous H2S generation, especially the response speed and degree of H2S-generation-associated members, to both developmental and environmental cues in Solanum lycopersicum L. are still poorly understood. Here, we identified and charactered the H2S-generation-associated enzymes in tomato, including O-acetylserine (mercaptan) lyases (OAS-TL), L/D-Cysteine desulfhydrases (L/D-CDes) and nitrogen fixation S (NIFS)-like enzymes, possessing LCD-like activity. Analysis of cis-regulatory elements (CREs) showed that the promoter regions of these H2S-generation-associated genes contained lots of light-, hormone- and stresses-responsive CREs, and transcriptional factors (TFs) binding sites, suggesting that the regulatory mechanism of endogenous H2S generation might involve TFs mediated transcriptional regulation or/and interacting with phytohormones signals. Levels of endogenous H2S exhibited diversity in different organs and developmental stages in tomato, and the top and second highest level of H2S in flowers and ripened fruits hinted the significance of H2S signal in tomato reproduction and fruit development. Furthermore, the expression of SlOAS4, SlLCD, SlDCD2, SlNFS1, and SlNFS2 enhanced continuously during fruit ripening, and the SlOAS4 expression exhibited the most significant up-regulation. The SlDCD enzymatic activity responded more quickly to fruit development cues, while the SlLCD remained at a higher level almost throughout the whole fruit ripening. During environmental stimulus, it was found that the transcriptions of SlDCD2 and SlOAS2 responded faster and stronger to heat stress, while SlOAS4 and SlLCD were activated more quickly and significantly by drought stress. Both SlLCD and SlDCD enzymatic activities could be enhanced by drought and heat stress to varying degrees, and it seemed that the SlLCD was activated to a greater extent and remained at the higher activity for a longer period. With the extension of exogenous phytohormones (ABA, SA, GA, JA, ACC, NAA) treatment, the SlLCD activity and the endogenous H2S content increased in a specific time-dependent manner, and ABA, SA and NAA had more rapid effects on SlLCD activity. By widely explored the dynamic responses of endogenous H2S generation, our study would provide some references for understanding the regulatory mechanism upstream of H2S signaling in tomato growth developments and environmental adaptations.

The Importance of the Classroom's Window View

Many studies point out the importance of the window views to the surroundings, as they have a significant impact on children's well-being, living comfort and learning performance. Nevertheless, this aspect is overlooked and usually not included as one of the main criteria for designing school facilities in an urban area. The purpose of the study was to find out how the students are responding to the potential of classroom’s window views. To collect data a questionnaire was implemented in three Slovenian primary schools (in the third triad). The respondent were pupils from three different Slovenian regions. The results were processed with the statistical package SPSS for Windows and with the MS Excel tool. The pupils answered consistently to the questions in the survey. They like their classroom because of the large windows with lots of light and because of the window view of green areas. Most pupils prefer to sit by the window because they like to look outside at the surroundings. Otherwise, they would prefer to look at water, greenery, and nature. The least they would like is the view of neighbouring buildings nearby, especially if the view is without greenery, or of a busy street. They like to look out the window, even if sitting by the window is sometimes unpleasant if too hot in the summer or too cold in the winter. The noise passing through the window clearly does not bother them. The result of the study can be helpful in designing school facilities in an urban environment.

The orientation of residential development in Mashhadthat takes account of daylight

Introduction. Due to population growth and urbanisation, energy consumption by urban buildings, especially in developing countries, is increasing dramatically. Limited energy resources and the need to save on consumption necessitate the optimal design in the field of residential development. Building walls are an important boundary between indoor and outdoor spaces, since daylight has a direct impact on energy consumption in buildings. The optimal use of daylight in living spaces reduces energy consumption dramatically. In this regard, the proper orientation of residential buildings is an effective method of energy consumption optimisation. If the layout of an urban development fits the climate of a region, residential buildings are constructed with account taken of the optimal orientation to daylighting.
 Materials and methods. The aim of this study is the optimal orientation of a part of residential development in Mashhad. To achieve the goal of the study, comprehensive studies of the city of Mashhad and its environs were conducted and Mashhad climate data were collected. Hence, daylight scattering was analysed for a given area with regard to the optimal angle of orientation to daylighting. Daylight was analysed in the two modes, including the present-day layout and the angular position (the north side), that were compared later. The study area has the angle of 20 degrees from the north to the west. All analyses and simulations were performed on the longest (June 22) and shortest (December 22) days of the year using parametric software programmes Grasshopper and Ladybug.
 Results. A comparative analysis of the two modes shows that the study area, located in the north, receives more daylight, regardless of the angle of rotation. Mashhad summers are hot and dry, and winters are cold and humid; a lot of light can penetrate into buildings during the hot season. In winter, overshadowing by buildings does not allow enough daylight due to the unfavourable location of the residential development. According to the standard, the optimal rotation angle of buildings in Mashhad varies from 5 degrees northeast to 20 degrees northwest.
 Conclusions. The results show that the optimal daylight orientation in Mashhad is 20 degrees southeast. This value is in the standard range for the residential orientation, and the amount of light, received in summer and winter seasons, is proportional to the needs of indoor space users; natural lighting makes residential spaces more comfortable and reduces energy consumption.

Information Literacy, an Investigation into Students’ Access and Use of Information in an Academic Institution in Ghana

In modern times, a lot of light has been thrown on Information literacy by empirical studies due to its significant role in facilitating access to information and use as well as lifetime learning. It is one of the main factors responsible for the information explosion and a key determining factor for students’ success in academics. The study gauged students’ attitudes on the IL programmes of the University for Development Studies (UDS) using both qualitative and quantitative research approaches. The study discovered that students did not consider the library as a source of academic knowledge and information since their frequency of visiting was low. The study also showed that 43.1% of the respondents go to the library at least once a week while the majority (56.9%) of the respondents either visited the library once a month or not at all. Early Childhood and Basic Education, Development Education, Social Change Communication and Renewable Natural Resources, are the courses pursued by those who utilized the library every day. Alternatively, no student pursuing B. Ed Business Studies made use of the library daily and 48.6% of them did not enter the library at all. The majority (58%) of the respondents had not been oriented on the use of the library. It was realized that 49.8% were knowledgeable of the fact that electronic resources are available in the library. The remaining (50.2%) did not have any knowledge of electronic resources in the library and were unlikely to make use of them. The utilization of electronic resources also varied according to programmes of study. Students who had comparatively higher access to such resources were pursuing Early Childhood and Basic Education. The study also realized that students’ interest in participating in Information Literacy programmes in the university increased and this increased the quality of their information literacy skills. With their awareness and know-how in information literacy, they can use the internet to retrieve the necessary information for academic work. The study makes some recommendations, Principals and Deans should coordinate to organize more Information Literacy Programmes, increased staff participation in the teaching of the IL Programmes and lastly, implementation of Academic Board pronouncements on the IL Programme. This will go a long way to improve access and enhance the use of information in the university.

The effect of salicylic acid and jasmonic acid solution spray on soluble sugar, proline and enzymes of lavender (Lavendula officinalis L.) under salt stress.

Introduction Today medicinal plants are an important part of the traditional medicine in many countries, they also have a special place and high value in new therapeutic approaches. Iran is one of the major habitats of many medicinal plants, one of these medicinal herbs, lavender with the scientific name (Lavendula officinalis L.) is an evergreen plant from Lamiaceae family. Lavender belongs to arid and semi-arid areas. It needs lots of light, warm weather and less humidity during growth. Under such conditions, the performance of the flower, essence, as well as the quality of the essence increases. Salinity is the presence of soluble salts and mineral elements in water and soil that will lead to the salt accumulation in the root area so that the plant will face difficulty absorbing enough water from the soil solution. Soil salinity is one of the most important factors limiting crop yields around the world, that this issue, particularly in arid and semi-arid areas is considered as one of the most fundamental problems of agricultural sector. Iran, with warm and dry climate is no exception to this issue. More than half of its arable lands (around 27 million hectares) is formed from salty soil and sodium. So in order to make the optimal use of these lands and saline water resources, a reformative important approach is to boost plant tolerance associated with higher production capacity. To deal with the stress, plants have a defense system with high efficiency which can destroy or neutralize free radicals. This defense system, includes enzymatic and non-enzymatic mechanisms. according to the above mentioned items, this study was done to investigate the effect of salicylic acid and Jasmonic acid on the soluble sugars, Proline, activity of antioxidant enzyme of lavender herb (Lavendula officinalis L.), in salinity tension situation to reduce the bad effects of tension. Materials and Methods To investigate the effect of Salicylic acid and Jasmonic acid solution on soluble sugar, Proline and antioxidant enzyme activity of lavender herb in salt tension situation, the pot experiments was done in 1393 in Azad Islamic University, Yadegar Imam Khomeini (RAH) branch of Ray city also the greenhouses that located in strict 4. The experiment was done through a factorial arrangement in a completely randomized basis with four replications. The experimental factors were included salt stress from salt (NaCl) in four levels (0, 25, 50 and 75 mM), Salicylic acid in two levels (0 and 0.7 mM), and Jasmunic acid in two levels (0 and 100 mM). Results and Discussion The results of the comparison of the salinity average simple effects showed that this factor caused an increase in soluble sugar, proline, activity of antioxidant enzymes such as Catalase, Superoxide dismutase, Peroxidase, Ascorbate peroxidase and Glutathione peroxidase. According to the research, the use of Salicylic acid, Jasmonic acid through increasing the activity of soluble sugar and proline, increased plant resistance in saline conditions. The results of the study also showed that only the interaction of the three attributes of treatments of the experiment on Peroxidase, Ascorbate peroxidase’s traits was significant. In this case, the highest Peroxidase activity (50/27 mg pr/min) and ascorbate peroxidase (24/12 mg pr/min), in salinity factor 75 mM and the absence of the two mentioned compounds was obtained. Conclusion According to the results of the experiment, it can be confirmed that following the use of Salicylic acid and Jasmonic acid under salt stress, proline and soluble sugars contents were increased and antioxidant enzyme activities were decreased. In other words, while using these two compounds, the lavender medicinal herb has used soluble sugar and Proline to cope with the salt stress.

The question is re-addressed in recent big trials, however the big dilemma doesn't resolved. This perspective touch upon the ancient as well as current evidence of OFS in these young early breast cancer women and try to enlighten the readers further on this controversial topic wherein there is lots of light but little illumination.

Nighttime restlessness in people with dementia in residential care: an explorative field study

Nighttime restlessness in dementia is an underestimated problem. Although little is known about the prevalence and not every person with dementia struggles with it, nighttime restlessness puts a heavy burden on the persons themselves and their caregivers.This field study explores nighttime restlessness in nursing homes based on two research questions: (1) What is nighttime restlessness according to professional caregivers? and (2) How is nighttime restlessness managed?Data were collected through diaries, interviews with caregivers and one night of observation in eight nursing homes.Wandering and screaming seem to be the most prevalent nighttime agitated behaviours. Caregivers identify many possible causes, but spatial and sensory factors, such as light or noise, were rarely mentioned spontaneously. The observations highlighted that a lot of light and noise is prominent and this might be causing nighttime restlessness.Caregivers try several strategies: for example talking with the resident, put on a light and apply medication or physical restraints.The management of nighttime restlessness requires a holistic approach. Caregivers' attention for and efforts to ameliorate the spatial and sensory environment in the management of nighttime restlessness are limited.

α-Glucan biosynthesis and the GlgE pathway in Mycobacterium tuberculosis.

It has long been reported that Mycobacterium tuberculosis is capable of synthesizing the α-glucan glycogen. However, what makes this bacterium stand out is that it coats itself in a capsule that mainly consists of a glycogen-like α-glucan. This polymer helps the pathogen evade immune responses. In 2010, the biosynthesis of α-glucans has been shown to not only involve the classical enzymes of glycogen metabolism but also a distinct GlgE pathway. Since then, this pathway has attracted attention not least in terms of the quest for new inhibitors that could be developed into new treatments for tuberculosis. Some lines of recent inquiry have shed a lot of light on to how GlgE catalyses the polymerization of α-glucan, using α-maltose 1-phosphate (M1P) as a building block and how the pathways are regulated. Nevertheless, many unanswered questions remain regarding the synthesis and role of α-glucans in mycobacteria and the numerous other bacteria that possess the GlgE pathway.

Duke-Elder’s Views on Prognosis, Prophylaxis, and Treatment of Myopia: Way Ahead of His Time

ABSTRACTSir Stewart Duke-Elder was probably the most influential ophthalmologist of the 20th century. One of his visionary pieces of work was his writing on myopia in the second edition of The Practice of Refraction, published in 1935. Many of his insights are now, 80 years later, supported by scientific proof. In terms of prognosis of myopia, he stated that this largely depended on the age of the patient. We now have epidemiologic evidence that age of onset is strongly related to final refractive error, and that high myopia carries a high risk of blindness. With respect to prophylaxis, he claimed that accessory risk factors were excessive near work, bad ocular hygiene, and physical debility in the early years of growth: “The régime of modern schools imposes far too much application to books upon young children at an age when they require all their available vitality for physical growth and development.” He recommended open-air pursuits and avoidance of indoor activities, in particular for children with a hereditary tendency toward myopia. Current investigations indeed point to a crucial role for near work, although not all findings are consistent. The most established factor that is protective from myopia is outdoor exposure, more likely due to intense exposure to light rather than to “open-air.” Ocular hygiene and physical activity have not been confirmed as protective factors, but Duke-Elder’s views on gene–environment interactions are truly insightful. Concerning treatment, he suggested that adequate correction by glasses, intake of vitamin D, and restriction of education in “myope classes” could halt progression of myopia. Optical correction is considered helpful nowadays, but sound statistical evidence has only been provided for orthokeratology. High vitamin D serum levels are indeed related to low refractive error, but it is not yet clear whether high dietary intake is beneficial. Restriction of education does not meet current moral standards, but in China, “myopia classrooms” in the form of large cubes of windows, admitting lots of light, have been built. In this report, we highlight Duke-Elder’s insights into the causes and clinical care of myopia, and discuss their merit for ophthalmic care today.

Tangier, Spanish Morocco and Spain's civil war in Dutch diplomatic documents

This article presents the consequences of the Spanish Civil War (1936–39) on the International city of Tangier as well as on Spanish Morocco through the eyes of the Dutch diplomatic representation in the international zone. These documents derive their importance not only because of the diplomatic status of their authors, but also because the Dutch consul general was one of seven envoys that constituted the Control Committee in Tangier and as such formed part of the governing body of the city. The documents shed a lot of light on the circumstances and crises that threatened the neutral status of Tangier during the early days of the war, and also afterwards. The Dutch reports however, also disclose the antipathy that the Dutch held towards the Spanish Republicans whom they usually branded as red or communist and often attributed to them occasional troubles in Tangier. The frequent visits to Spanish Morocco by the Dutch envoy as well as the conversations with the Spanish High Commissioners in Tetouan provide first-hand testimonies on the state of mind and fears, that sometimes bordered on the excessive, of the Spanish authorities in the Moroccan protectorate. These documents are an important source of historical material for those interested in the modern history of Tangier as well as the role of Morocco in the Spanish Civil War.

How to Grow Tomatoes

INTRODUCTIONTomatoes can be easily grown in a field, in a greenhouse, or in a growth cabinet. They need acidic soil (pH 6.0-6.8), a lot of light, and water. The optimum temperature for growing tomato plants and fruit is 18°C-24°C. This protocol describes how to germinate tomato seeds, cultivate adult plants, and harvest seeds from fruit.

A survey of breast cancer awareness and knowledge in a Western population: lots of light but little illumination

There are conflicting data on breast cancer awareness and knowledge in specific population groups. We assessed awareness and knowledge of breast cancer in the general Irish population to identify sources of information on breast cancer and determine factors associated with knowledge and awareness of the disease. Participants ( n = 2355, 53% female) completed a multi-part questionnaire. Most (81%) had seen or heard something about breast cancer in the recent past and knowledge of symptoms and treatment was good overall. However, 66% of females overestimated their risk of developing disease, 88% underestimated the age at which it was most likely to develop and 56% underestimated 5-year survival. Knowledge of incidence and survival was higher in males (Odds Ratio (OR) 1.3, 95% Confidence Interval (CI); 1.1–1.5), participants with higher education (1.5; 1.2–1.7) and those who received information from television (1.3; 1.1–1.5). Ignorance regarding incidence, outcome and risk makes it unlikely that the general public or at risk females could currently make informed decisions on a range of breast cancer issues.

Reduplication of nominal modifiers in Singapore English: a semantic and cultural interpretation

Abstract: While the formal properties of reduplication in many languages have aroused the interest of many linguists and much appears to have been done in this area, the same cannot be said about its semantics. It seems that our understanding of the kinds of meaning associated with reduplication processes remains rather limited. This is regrettable, given that language meaning can shed a lot of light on the speech community's ways of thinking and norms of interaction. In this paper, the object of study is a widely used reduplication process in Singapore English – the reduplication of nominal modifiers. I will endeavour to identify its meaning and articulate it in the form of a reductive paraphrase. I will also try to show that its use may be linked, via meaning, with a culture‐specific norm of interaction that seems to be characteristic of Singapore English speakers.

The arms trade: winners and losers

The arms trade Winners and losers The arms trade is highly controversial and raises difficult policy issues. The controversies tend to concentrate on the moral, military and political dimensions of arms exports decisions. Quite a lot of light can be shed on this murky market by asking basic economic questions and using standard economic models. We begin with a structured economic description of the evolution of the international arms market in terms of the factors that influence demand and supply and thus prices and quantities. Then we review the policy issues faced by EU members: in particular, whether a common control regime is needed to harmonize their regulation of arms exports. To address these policy issues, we present some models of the market that we have developed and examine their implications for the interesting interactions that characterize the trade. — Paul Levine and Ron Smith

The Influence of Certain Methods of Management on Egg Production

I. Concluded. Their influence from March to August.The first report on these experiments was carried to March 1st, 1924. (Goodale ’24.) The monthly egg yield to August first, when the experiments were discontinued, is given in table III which shows essentially the same production in each group except the one receiving milk, whose production, calculated from the grouped data instead of the ungrouped data of table III, exceeds that of the cod-liver oil, lights lot, which has the lowest production, by 9.3±4.2 eggs, a difference that cannot with certainty be attributed to the milk in the ration. The several methods of management employed, therefore, can be said to be without marked influence on egg production.It is necessary to record a disturbing factor which inadvertently affected only a part of the birds. Late in January, the older half of each group, previously in pens of twenty-five each, were combined, .
