Small cell carcinoma of the ovary hypercalcemic type (SCCOHT): report of three cases and literature review

Small cell carcinoma of the ovary, hypercalcaemic type, (SCCOHT), is a rare ovarian tumor featured by hypercalcaemia, onset at early age and poor prognosis [1, 2]. This type of undifferentiated malignant tumor was first described early in 1979 with unknown histogenesis, based on the appearance of small and hyperchromatic cells [3]. SCCOHT accounts for 0.01% cases of ovarian tumors mainly in young females under the age of 40 with a median age of 24 years, usually causing unilateral pelvic masses, vomiting, infertility, and other systemic symptoms [1, 4]. Epithelial, neuroendocrine and sex cord-stromal origins, and various other hypothesis have been postulated over past decades about the etiology of SCCOHT, but none of them were fully supported and accepted [3]. Due to the lack of typical histological features, the diagnosis of SCCOHT is extremely challenging, difficult to distinguish it from other ovarian malignancies such as germ cell tumor, intra-abdominal desmoplastic small round cell tumor, and primitive neuroectodermal tumor [3, 5]. Recent investigations revealed various genetic mutations associated with SCCOHT development, such as SMARCA4 and SMACB1 genes [6-8]. More observations of the specific clinical and molecular features are pressingly needed for SCCOHT early diagnosis and effective therapy. In this report, the authors describe three cases of small cell carcinoma of the ovary hypercalcemic type (SCCOHT), followed by a literature review of its clinicopathological features, molecular basis, as well as clinical diagnosis and treatment.
Aquatic bryophytes in Himalayan streams: testing a distribution model in a highly heterogeneous environment

Summary 1. Aquatic bryophytes were sampled from 108 streams spanning over 3000 m of altitude in four regions of Nepal. Richness, cover and community composition were related to physicochemistry using multiple regression, DECORANA ordination and TWINSPAN. The performance of a hierarchically scaled descriptive model, developed in New Zealand for predicting bryophyte distribution, was examined in this highly heterogeneous Himalayan region. 2. Community composition and cover varied highly significantly with altitude, streambed stability and alkalinity, with evidence of effects of riparian land use on bryophyte cover. Cover was greatest in streams at low to middle altitudes with steep slopes (> 15°), high stability and low conductivity (< 60 μS cm–1), where communities were dominated by two Isopterygium spp. , two Philonotis spp. , Mnium punctatum and Lejeuneaceae. 3. Richness, by contrast, increased significantly but weakly at high altitude and moderate stability, where streams were dominated by Eurynchium praelongum, Rhynchostegium spp. , Fissidens grandifrons and Hygroamblystegium spp. Richness and cover were lowest in unstable streams at the lowest altitude, where no single taxon was consistently most abundant. 4. Although these results were similar to those in the descriptive model developed for bryophytes in New Zealand, subtle differences were apparent. Substrate size, although influencing the presence of bryophytes in New Zealand streams, appeared to be unimportant in Nepal. By contrast, streambed stability was more important in Nepal than New Zealand, perhaps reflecting pronounced monsoonal floods, and subsequent increased frequency of bed movement in the former. A suggested habitat template indicates that large plant size and vegetative reproduction may be responsible for the widespread distribution of some species, even into unstable Himalayan streams.
"I like the way the skin looks": Player perspectives on aesthetic appeal and self-representation with video game "Skins"

Microtransactions are the purchasing of in-game items in video games, often using real money. Through microtransactions, game players can obtain a type of cosmetic called “skins” that change the physical appearance of playable characters. Considering the default “skin” in many games is that of a white male, there are various psychosocial and economic costs that may be extended to players of color when attempting to select skins for their avatars. To examine how players of different racial and ethnic backgrounds interact with “skins,” and the additional costs associated with them, we conducted a survey asking participants about their spending patterns with “skins” and reasons for choosing certain “skins” over others. The most common response from participants when asked why they select their skins was “because I like the way the skin looks. ” As this statement is broad, we delve into other results from our survey and previous studies by other scholars to analyze what this response may be able to tell us about players who selected this as their answer.
Effect of various irrigation frequencies on the yield and yield components of sunflower

The effect of irrigation frequencies i.e. 0, 2, 4, 6 and 8 was studied at the Faculty of Agriculture, Gomal University, Dera Ismail Khan, during the year 1995. The parameters like plant height, head diameter, number of grains per head, 1000-grain weight and grain yield per hectare were significantly affected by irrigation levels and six irrigations were found optimum for obtaining good yield of sunflower. On the basis of research findings, six irrigation are recommended for sunflower crop to obtain maximum seed yield under irrigated conditions.
Physiological response of largemouth bass to angling stress

Abstract The physiological effects of catch-and-release fishing on largemouth bass Micropterus salmoides from Lake Powell and Mantua Reservoir, Utah, were evaluated, and an estimate of the time needed for recovery from hooking stress was obtained. Fatigue in Lake Powell fish, as indicated by elevated blood lactate, was directly proportional to hooking time (1–5 min) and water temperature, but recovery from the hyperlacticemia was relatively rapid (about 24 h). Hyperglycemia, an indicator of stress hormone production, did not occur in largemouth bass hooked and played for 1–5 min in the coldest water (11–13°C), was moderate in fish hooked and played at l6–20°C, and was severe in fish played for 5 min at 28–30°C. Fish held for recovery in live cages suffered further hyperglycemia, presumably because of the stress of confinement. Ionoregulation, as indicated by relatively stable plasma chloride values, was not immediately affected in largemouth bass caught at water temperatures of 11–13°C or 28–30°C, but an .
Supervisory feedback in the principal evaluation process

The purpose of this qualitative study is to understand how school principals perceive their supervisors’ feedback in the formative principal evaluation process. It spotlights the benefits of supervisors giving effective feedback to school principals as a key component in formative evaluations. In addition, it uses a qualitative case study design situated within the context of the Al-Ain school district, which is supervised by the Abu Dhabi Education Council in the United Arab Emirates. The data was collected using several data collection methods, namely interviews, documents, and field notes. Six school principals participated in the study, and a thematic analysis of their comments and other information that they provided yielded four themes that reflected the quality of feedback they received: (1) feedback in absentia, (2) superficial or irrelevant feedback, (3) negative or judgmental feedback, and (4) constructive and individualized feedback. The evidence concludes that feedback aimed at improving the leadership practices of principals is limited, and there is no embedded professional learning dialogue wherein such feedback exists. This study adds to the body of leadership literature and sets forth implications for enhancing and redesigning feedback delivery in the formative evaluation process to improve principals’ practices and support their professional growth.
Comparative growth and biomass allocation of two varieties of cat's claw creeper, Dolichandra unguis-cati (Bignoniaceae) in Australia

Introduced as an ornamental vine, cat's claw creeper Dolichandra unguis-cati (syn. Macfadyena unguis-cati) has invaded coastal and subcoastal areas of subtropical eastern Australia. Two varieties have been indentified, one of which ('short-pod') is found throughout south-eastern Australia, while the other ('long-pod') appears to be restricted to several sites in south-eastern Queensland. We compared the growth and biomass allocation patterns of the two varieties in the field over a 22-month period to determine if a higher growth rate and/or more efficient allocation of biomass may contribute to this disparity in distribution. The long-pod variety produced greater aboveground and total biomass than the short-pod variety in both riparian and non-riparian zones. Belowground the two varieties produced a similar number of tubers and overall biomass, though the long-pod variety allocated a smaller portion of its carbon belowground. High growth rates and greater biomass allocation aboveground are characteristic of invasive species, allowing them to outcompete and crowd out existing vegetation. There was no significant site by variety interaction, an indication of consistency in variety performance across riparian and non-riparian sites. Results from our study suggest that differences in growth and biomass allocations are unlikely to have contributed to the disparity in distribution of the two varieties. Despite currently occupying a relatively small range, the long-pod variety may be a more adept invader than the short-pod variety, and could become more prevalent in the future. © 2012 CSIRO.
Effects of dietary cholesterol levels on moulting performance, lipid accumulation, ecdysteroid concentration and immune enzymes activities of juvenile Chinese mitten crab Eriocheir sinensis

Effects of dietary cholesterol levels on moulting performance, lipid accumulation, ecdysteroid concentration and immune enzymes activities of juvenile Eriocheir sinensis were investigated. Crabs were fed with feeds contained various cholesterols of 1100, 2100 and 3200 mg kg−1 in both paddy fields and laboratory experiments. In paddy fields trial, the crabs fed with diets contained 3200 mg kg−1 cholesterol achieved higher growth rate than those fed with diets contained no supplemental cholesterol (1100 mg kg−1). In laboratory trial, moulting frequencies of crabs fed with diets contained 3200 mg kg−1 cholesterol were higher than those of crabs fed with diets contained no supplemental cholesterol from the 6th to 10th moult. Further laboratory experiment indicated that intermoults of crabs fed with diets contained 3200 mg kg−1 cholesterol significantly shortened compared with crabs fed with the basal feeds (1100 mg kg−1 cholesterol). In the intermoult, total lipid content, ecdysterone concentration and three immune enzymes in crabs were increased with the increment of dietary cholesterol levels between the 7th and the 8th moult in laboratory experiments. Taken together, dietary cholesterol not only enhanced moulting performances of growth, survival and moult frequency, but also enhanced total lipid storage, ecdysterone concentration and three immune enzymes activities in the intermoult period.
EFFECTIVENESSOF CASEIN PHOSPOPEPTIDE AMORMPHOUS CALCIUM PHOSPHATE WITH OR WITHOUT FLUORIDE ON REMINELIZATION OF ENAMEL CARIES- LIKE LESIONS IN PRIMARY TEETH

Abstract: Objective: To evaluate and compare the remineralization effect of casein phospho-peptide amorphous calcium phosphate with or without fluoride “MI paste”&“MI Paste Plus” respectively” on the re-mineralization of enamel caries-like lesions in primary teeth. Material and methods: Artificial caries lesion was made on the labial surface of 40 extracted or exfoliated sound primary teeth which were then divided into 2 halves; one half was treated with one of the tested remineralizing agent “MI paste” or “MI Paste Plus”” while the other half served as a control. The lesions were evaluated both qualitatively using a polarized light microscope and quantitatively by measuring “calcium and phosphate” content using “energy-dispersive X-ray spectroscopy”. Data were collected and analyzed by using paired t-test to compare the control and the study groups for each material, while the “t-test” was used to compare between the two study groups. Results: Both “MI paste” and “MI Paste Plus” showed significant re-mineralization to the subsurface enamel lesions. “MI Paste Plus” showed significantly better results than “MI paste” with an increased amount of calcium “t=5.59 p=<0.0001”, Ca/phosphate ratio “t=4.08 p=0.003” and reduction in the amount of phosphate content “t=4.57 p= 0.001”. Conclusion: Both “MI paste” and “MI Paste Plus” were effective in enamel remineralization, the addition of fluoride in “MI Paste Plus” acted synergistically with the casein phospho-peptide amorphous calcium phosphate and gave better remineralization effect on enamel.
High population connectivity and Pleistocene range expansion in the direct-developing plough shell Bullia rhodostoma along the South African coast

Pleistocene climatic and oceanographic changes have influenced the distribution of marine biodiversity in southern Africa. Most evidence, however, has been derived from rocky shore or demersal taxa; data on sandy shore species are limited, despite severe threats to many sandy beach ecosystems. To test the effects of past climatic changes on sandy shore species, we sampled 140 smooth plough shell Bullia rhodostoma individuals from eight localities and generated phylogeographic data derived from the mtDNA cytochrome c oxidase subunit 1 (COI) marker. Nuclear markers (ATPSα, ATPSβ, ANT, SRPS4, TBP, LTRS and ZMP) showed no sequence variation. Bullia rhodostoma exhibited shallow genetic differentiation (ΦST = 0.07, p < 0.05) across its range. Isolation-by-distance suggests a stepping-stone model of migration, which is expected given the species’ direct-development life-history strategy. Demographic reconstruction suggests a post-LGM (Last Glacial Maximum) range expansion, concordant with the signal of shallow genetic differentiation. Phylogeographic patterns obtained suggest that, during lower sea levels than current, B. rhodostoma could have been restricted to the South-West Coast, the central Agulhas Bioregion and probably also the East Coast. When climatic conditions changed and temperatures began to rise after the LGM, the species began a rapid westward range expansion from these refugial regions.
Pika burrow and zokor mound density and their relationship with grazing management and sheep production in alpine meadow

Plateau pikas (Ochotona curzoniae) and plateau zokors (Myospalax baileyi) occur naturally in the alpine meadow of the Qinghai–Tibet Plateau (QTP). Their feeding and burrowing activities affect plant composition and soil properties (e.g., soil carbon accumulation and soil nitrogen cycling), but research to study the complex interactions between small mammals, livestock, and habitat is currently lacking. We conducted a sheep grazing trial to determine the effect of grazing management on pika burrow and zokor mound density, and the relationships between sheep production and pika burrow and zokor mound density. The grazing management approaches were warm-season rotational grazing at 24 and 48 sheep months (SM)/ha, cold-season rotational grazing at 24 and 48 SM/ha, seasonal continuous grazing at 24 SM/ha, and whole-year continuous grazing at 48 SM/ha. The results of this study suggested that warm-season rotational grazing at low stocking rate did not significantly change both pika and zokor densities. Cold-season rotational grazing at both high and low stocking rates and seasonal continuous grazing at low stocking rate led to an increase in zokor mound density, but not pika burrow density. Whole-year continuous grazing at high stocking rate increased both pika and zokor densities. The influence of pika and zokor activities on sheep production was complex and differed between grazing management. Sheep liveweight gain peaked at moderate pika burrow and zokor mound density at low stocking rate under both warmand cold-season rotational grazing. The threshold values of pika density were about 110 and 70 burrows per hectare in warm and cold seasons, respectively. The threshold value of zokor density was about 400 mounds per hectare in the cold season. In contrast, under high stocking rate regardless of management approach, sheep liveweight gain declined significantly as both pika burrow and zokor mound density increased. This paper provides a theoretical understanding and experimental evidence for sustainable grazing management and restoration of degraded grassland by local herders and policymakers.
Novel-integrated process for production of bio-organic fertilizer via swine manure composting

The traditional method of producing bio-organic fertilizer contains two consecutive composting stages which, however, is time-consuming and requires high input of energy and cost. This study attempted to combine two consecutive stages into one single step. Paenibacillus polymyxa, as an antagonistic strain to control anthracnose in Chinese Pakchoi, was used as inoculum to obtain bio-organic fertilizers through two approaches: two consecutive stages (TCS) composting as control and the proposed one step through (OST) composting. The resulting two bio-organic fertilizers produced by TCS and OST were tested for the disease incidence and disease resistant index, and the fertility on growth of Chinese Pakchoi. The results of relative abundance of P. polymyxa showed no significant difference between two kinds of bio-organic fertilizers in phylum, family and genus. The disease incidence of bio-organic fertilizers produced by OST and TCS reduced by 61.40% and 68.42%, respectively, as compared to the control group, where the difference was not significant. The growth promoting effect was remarkable, although the difference in the fertility on the growth was not significant. Compared with the traditional TCS method, the novel OST method could improve efficiency of bio-organic fertilizer production by 42.86% per year according to this study.
Threatened and uncommon plants of New Zealand (2008 revision)

Abstract A reappraisal of the conservation status of the indigenous New Zealand vascular plant flora is presented using the 2008 version of the threat classification system developed for the New Zealand Department of Conservation. The list comprises 897 taxa (38% of New Zealand's total indigenous vascular flora) in the following categories: Extinct—6 taxa, Threatened—180 taxa (comprising 91 Nationally Critical taxa, 45 Nationally Endangered, and 44 Nationally Vulnerable), At Risk—651 taxa (comprising 83 Declining, 6 Recovering, 20 Relict, and 542 Naturally Uncommon taxa), 25 taxa listed as either Vagrant (12) or Coloniser (13), and 35 as Data Deficient. A further 171 plants are listed as taxonom ically indeterminate, being those which might warrant further conservation attention once their taxonomic status is clarified. Forty‐four recognised taxa and 26 plants rated as taxonomically indeterminate, and previously considered to be threatened and/or uncommon, are removed from this updated listing. A brief analysis of the patterns of rarity exhibited by the listed taxa is presented. Overall, the conservation status of the New Zealand indigenous vascular plant flora is worsening, with 7.6% of this flora now regarded as threatened with extinction. A concordance of plants names from the 2004 listing is provided.
Impact of supply chain management on Customer Loyalty to the ‘Aarong’ Fashion House Brand

Abstract- Achieving and retaining Customer loyalty is important objective for any business. Supply Chain Management synchronizes the efforts of all parties-particularly suppliers, manufacturers, retailers, dealers, customers-involved in achieving customer's needs. Customer satisfaction, retention rates, and the customer loyalty positively influence the performance of the business and assist to achieve competitive gain. Fashion house brands in Bangladesh are growing with developing some exclusive brands. Aarong is one of the prestigious and recognized brands in apparel industry of Bangladesh. The purpose of this research is to examine the factors that determine customer loyalty towards Aarong. In this research, ‘loyalty’ means customer perception about the brand and repurchase intention from Aarong. Independent Variables (factors) were chosen after interviewing customers with buying experience from Aarong, and previous studies on fashion industry. A non-probability judgmental sampling methodology was followed for primary data collection and 301 completed sample responses were collected. Descriptive statistics were conducted to describe the demographic information of the respondents; twelve factors were tested to find out their influence on customer loyalty toward Aarong. Principal Component Factor analysis was used to reduce the less significant factors and find the high significant factors. After data analysis it is found that three major factors labeled as customer perception about the brand, customers’ economic benefits and shopping environment. From these factors, the first factor which is customer perception about the brand found most significant factor to explain customer loyalty toward Aarong. These result might help Aarong to better segment the market and to create more effective marketing program. It may also give a guideline to other brands in the same industry and might be important literature for future researchers in apparel sector.
Amplified fragment length polymorphism analysis in diploid cultivars of rhodesgrass

The amplified fragment length polymorphism (AFLP) technique was applied to detect genetic variation in a sample of 47 plants representing 12 diploid cultivars of rhodesgrass. In this analysis, 50±91 easily scorable fragments could be detected in a single reaction. Each of the individual plants was uniquely identified by a combination of three primer pairs and an 80.2% level of polymorphism was obtained. Large amounts of genetic variation were present within all the cultivars. The results showed that AFLPs could be a robust technique for genome analysis in rhodesgrass with a promising potential as a breeding tool.
Physiological behaviour of canola seeds stored under different conditions of water content and temperature

O presente trabalho tem por objetivo determinar as condicoes de teor de agua, temperatura e tempo de armazenamento seguras para manutencao da qualidade das sementes de canola armazenados. As sementes foram armazenadas por 180 dias com os teores de agua de 8, 10, 12 e 14% (b.u.), nas temperaturas de 7, 17 e 27°C. No inicio e a cada 45 dias de armazenamento ate o periodo de 180 dias, foram realizadas as analises de germinacao, primeira contagem da germinacao, condutividade eletrica e envelhecimento acelerado das sementes de canola. O percentual de germinacao e o envelhecimento acelerado apresentaram reducao significativa ao longo do armazenamento para as amostras com 12 e 14% de teor de agua, armazenadas a 17 e 27oC. Com a elevacao do teor de agua e temperatura de armazenamento, houve aumento na condutividade eletrica das sementes. Assim, as temperaturas de 17 e 27°C ocasionam as maiores reducoes da qualidade fisiologica das sementes armazenadas com 12 e 14% de teor de agua. A temperatura de 7°C permite melhor conservacao das sementes nos teores de agua de 8, 10 e 12% armazenadas por 180 dias.
