Increasing of special physical fitness of the female athletes practicing sambo

Background and Study Aim: A high level of special physical fitness is necessary achieving high results in combat sports (martial arts). The purpose of the study is knowledge about effective methods increasing the level of special physical fitness of the junior female practicing sambo. Material and Methods: The participants 17-18 years old female (n = 21) practicing sambo for more than 4 years. The study period had been conducted for 32 weeks. Various methods of level increase of athletes’ functional fitness were used. The group A (n = 11) had used randori (sparring) and throws at a fast pace. The group B had used the functional training and randori. The physical fitness indicators of the female athletes to assess: Special Judo Fitness Test (SJFT), lactate concentration in the blood, test with execution of 30 ippon-seoi-nage (throw) analysis of competitive results. Results: The female athletes from the group B had showed significant (p<0.05) superiority of SJFT results. The level of lactate concentration in the blood was significantly (p<0.05) lower after SJFT among the female of the group B. The test with execution of 30 ippon-seoi-nage had not revealed significant differences of the recovery parameters among the female. The competitive results of the female of the group B were significantly (p<0.01) higher. Conclusions: The presented training practice methodology allows increasing the level of special physical fitness of the female athletes significantly without apparent increase of the training loads amount.
Effects of tillage systems and crop rotations on root and foliar diseases of wheat, flax, and peas in Saskatchewan

The dynamics of root and foliar diseases were studied in spring and winter wheat, peas, and flax and under zero, minimum, and conventional tillage at Indian Head, Saskatchewan, from 1987 to 1990. No disease was observed on flax during the 4 yr. Year-to-year variation was more important than tillage systems in explaining the incidence of bacterial leaf spot and foot rot of peas. Tan spot and septoria leaf blotch were the most important foliar diseases of wheat. Disease ratings (0–9) of the leaf spots were greater on winter wheat (average 2.2) than on spring wheat (average 1.9) and also greater on spring wheat following a cereal (average 2.0) than following peas or summer fallow (average 1.7). Hot and dry weather did not enhance development of foliar diseases, and no consistent effects of tillage on leaf disease ratings were observed. However, take-all and common root rot were affected by crop management. Incidence of take-all was greater on winter wheat (8%) than on spring wheat (1%) and also greater on wi.

Preliminary Report on the Absence of Toxicity of Fruit Pulp of Palmyrah (Borassus Flabellifer L.) In ICR Mice

Palmyrah (Borassus flabellifer L.) flour prepared from the seed shoot has been previously reported to cause hepatotoxic, neurotoxic and other toxic effects. Although palmyrah fruit pulp (PFP) is also consumed in Sri Lanka, no toxicity studies have been done. Short and long term toxicity studies were therefore conducted with PFP by administration of 10% or 50% PFP (dry basis) incorporated into WHO standard feed (part of the maize being substituted with PFP) compared with a control group of ICR mice, fed the WHO standard feed (n=7 in each group, age 6 weeks, weight 36- 44g) , for 7 or 30 days. In both studies the effect of 10% or 50% PFP feed on liver and kidney function and haematological parameters (haemoglobin concentration, packed cell volume, white blood cell count and red blood cell count) were determined. Liver function was assessed by estimation of serum levels of alanine transaminase, aspartate transaminase and alkaline phosphatase. Renal toxicity was assessed by estimation of serum creatinine levels. In the long term toxicity study, effect of PFP on histology of main body organs (heart, lung, liver, kidney and intestine) were also assessed by microscopic examination of haematoxylin / eosin stained sections of these organs. Results of both the short term and long term toxicity studies demonstrated that PFP at the 10% or 50% level did not have any significant effect on kidney or liver function nor on the haematological parameters under study and on the histology of major body organs in ICR mice. In all studies, neurotoxicity was assessed by comparing the behaviour ofthe test group with the control group. No behavioural changes or spasms were observed in the test groups of mice fed with the feed containing 10% or 50% PFP. The overall results suggest that PFP even at the 50% level in the standard feed probably does not produce any toxic effects in ICR mice.
Population structure of Sind sardinella Sardinella sindensis (Day, 1878) in northern Persian Gulf and Oman Sea, Iran

The population dynamics of Sardinella sindensis (Day, 1878) was studied from samples in the commercial fishery in the coastal waters of the Persian Gulf and Oman Sea. A total of 12,898 specimens were collected through monthly sampling of boat purse seine and beach seine catches. Total length of the sampled fishes ranged from 5.0 to 19.9 cm. The von Bertalanffy growth parameters determined using monthly length frequency distribution were asymptotic length (L∞ = 21 cm), growth coefficient (K = 1.2 year-1) and age at zero length (t0 = -0.14 year). The estimated value for longevity (tmax) was 2.5 years. The probability of capture was calculated as Lc25=10.2 cm, Lc50=10.9 cm and Lc75=11.8 cm total length. Four cohorts with mean lengths of 7.2, 11.7, 15.7 and 18.6 cm were discerned in a year, with two recruitment peaks. The calculated length-weight equation was W= 0.0078 L3.02. The instantaneous rates of mortality (Z) was estimated as 4.02, with natural mortality M=2.19 and fishing mortality F=1.83 year-1. The exploitation rate (E) was 0.46, which was found to be reasonable for current fishing effort. From the yield-per-recruit analysis, Emax was estimated as 0.79, confirming that the stock is under optimum exploitation.
Timing of diapause in relation to temporally variable catastrophes

This paper analyses the response of the distribution of diapause switching times in an arthropod population with respect to variation in a catastrophe, which kills nondiapause individuals. For concreteness, the catastrophe will be taken to the onset of winter. The relationship between an individual's switching time and the decision whether to diapause is defined as follows: If she passes through the end of the sensitive period, during which the diapause decision is made, before her switching time, she will complete development and reproduce rather than diapause. If she passes through the sensitive period on or after her switching time, she will diapause. The model follows the evolution of the distribution of switching times for a population over a sequence of years. Random variation in the end of the season is created by sampling from a normal distribution of times at the end of the growing season. The model is for a haploid population in which the distribution of switching times that a female passes to her offspring is normally distributed having her switching time as its mean. This approximates a sexual population with strong positive assortative mating and heritability near 1. This mode of inheritance permits a rapid response to yearly changes in the end of the season as a contrast to earlier models, which incorporated a slow response. Patterns of temporal change in the median switching time are analyzed. The influences of three parameters are considered: the mean and standard deviation of the end of the season, and standard deviation of the offspring distribution.
Predict and Match: Prophet Inequalities with Uncertain Supply

We consider the problem of selling perishable items to a stream of buyers in order to maximize social welfare. A seller starts with a set of identical items, and each arriving buyer wants any one item, and has a valuation drawn i.i. d. from a known distribution.Each item, however, disappears after an a priori unknown amount of time that we term the horizon for that item. The seller knows the (possibly different) distribution of the horizon for each item, but not its realization till the item actually disappears. As with the classic prophet inequalities, the goal is to design an online pricing scheme that competes with the prophet that knows the horizon and extracts full social surplus (or welfare). Our main results are for the setting where items have independent horizon distributions satisfying the monotone-hazard-rate (MHR) condition. Here, for any number of items, we achieve a constant-competitive bound via a conceptually simple policy that balances the rate at which buyers are accepted with the rate at which items are removed from the system. We implement this policy via a novel technique of matching via probabilistically simulating departures of the items at future times. Moreover, for a single item and MHR horizon distribution with mean μ, we show a tight result: There is a fixed pricing scheme that has competitive ratio at most 2 - 1/μ, and this is the best achievable in this class. We further show that our results are best possible. First, we show that the competitive ratio is unbounded without the MHR assumption even for one item. Further, even when the horizon distributions are i.i. d. MHR and the number of items becomes large, the competitive ratio of any policy is lower bounded by a constant greater than 1, which is in sharp contrast to the setting with identical deterministic horizons.
Influence of fecundity on recruitment variability of marine fish

On a souvent soutenu que la forte variabilite du recrutement des populations de poissons marins etait une consequence de leur grande fecondite. Pour verifier cette hypothese, nous avons etabli une relation lineaire simple qui lie l'ecart-type du logarithme du recrutement pour une espece au logarithme de sa fecondite, et nous donnons une prediction specifique du coefficient de la pente. Nous testons ce resultat avec toutes les donnees disponibles sur les principaux stocks de poissons marins. Nous avons trouve que la relation derivee predit approximativement le taux de variabilite du recrutement par rapport au logarithme de la fecondite pour le centroide de la grappe de donnees ponctuelles, mais la dispersion autour du centroide est si grande qu'il n'existe aucune relation significative entre la variabilite du recrutement et le logarithme de la fecondite.
The Role of Women�s Leadership in Manufacturing Companies Listed on the Indonesia Stock Exchange

This study aims to determine the role of women in the board of directors in increasing company value through financial performance. The research object was all manufacturing companies listed on the Indonesia Stock Exchange in 2017. The sampling technique used purposive sampling on condition that the company had a board of directors and a female commissioner and did not experience a loss during the observation year. The research data used secondary data in the form of annual financial statements which were downloaded through the official website of the Indonesia Stock Exchange (IDX). Hypothesis testing used WarpPLS analysis. The results showed that the presence of women on the board had a negative impact on financial performance, financial performance had a positive and significant effect on company value, and the presence of women on the board had a significant negative effect on company value through financial performance.
Maternal size and age affect offspring sex ratio in the solitary egg parasitoid Anaphes nitens

In this study, the effects of maternal age, diet, and size on offspring sex ratio were investigated for the solitary egg parasitoid, Anaphes nitens Girault (Hymenoptera: Mymaridae), both outdoors, during the winter, and inside a climatic chamber under favourable constant conditions. During the winter of 2005–2006, each of seven groups containing 40 1‐day‐old females was mated and randomly distributed among two treatments: (treatment 1) a droplet of undiluted honey ad libitum + one fresh egg capsule of the snout beetle Gonipterus scutellatus Gyllenhal (Coleoptera: Curculionidae) as host; (treatment 2) drops of water + one fresh egg capsule of G. scutellatus. We recorded the lifetime fecundity, the daily sex allocation, and the lifetime offspring sex ratio to study the existence of a relationship with maternal characteristics. Moreover, we assessed the effect of location (outdoors vs. indoors) and group (groups are representative of early, mid, and late winter) on sex ratio. The most important factor that biased the sex ratio was maternal body size: larger females of both treatments produced more female offspring. As females of A. nitens could gain more advantage than males from body size, larger mothers have a higher fitness return if they produce more daughters. The effect of the treatment was significant: starved females produced more females. Location and group were not significant. Fecundity and sex ratio were age dependent. Old mothers that received honey (treatment 1) had fewer offspring and a more male‐biased offspring sex ratio, probably due to reproductive senescence and sperm depletion. Starved females (treatment 2) experienced reproductive decline earlier, perhaps because they invested more energy in maintenance rather than in reproduction.
Exploring the Anticancer and Anti-inflammatory Activities of Ferruginol in MCF-7 Breast Cancer Cells

Breast cancer is one of the most prevalent cancers in women, and it has the highest mortality and morbidity worldwide. Breast cancer can be treated by hormone therapies, radiotherapy, surgery, and chemotherapy, but it is often associated with multiple deleterious effects. In this present work, we explored the anti-inflammatory and anticancer effects of ferruginol in MCF-7 cells. The effects of ferruginol on the cell growth and viability of MCF-7 cells were determined by the MTT assay and apoptotic markers. In addition, mitochondrial membrane potential (MMP) status as well as the levels of intracellular reactive oxygen species (ROS), superoxide dismutase, catalase, glutathione, thiobarbituric acid reactive substances (TBARS), caspase-3 and caspase-9 in the ferruginol-treated MCF-7 cells were examined. In addition, expression of inflammation-related proteins such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), nuclear factor kappa B (NF-κB) p65, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) was determined using Western blotting. Our findings showed that ferruginol activated the apoptosis in MCF-7 through a reduction of cell viability. Furthermore, ferruginol-treated MCF-7 cells also showed a decrease of MMP, an increase of ROS, TBARS, caspase-3 and caspase-9, as well as a reduction of antioxidant proteins. Ferruginol treatment is also downregulated the expression of inflammatory modulators such as TNF-α, iNOS, COX-2, NF-κB p65, and IL-6 in MCF-7 cells. In conclusion, ferruginol inhibits the inflammation and activated apoptosis by modulating the expression of inflammatory and apoptotic markers. Therefore, ferruginol may serve as a potential curative agent for breast cancer.
Production of polysaccharide with Xanthomonas campestris

Industrially important polysaccharides are now primarily obtained from plant sources. One exception is the exocellular bacterial polysaccharide, dextran. A survey at the Northern Laboratory revealed that many other microbial polysaccharides could be synthesized by the action of micro-organisms on starch-derived saccharides. Previous publications from this laboratory describe the production of the microbial polymer, phosphomannan, synthesized by the yeast Hansenula holstii. This paper describes the production of another polysaccharide, synthesized by the bacterium Xanthomonas campestris NRRL B-1459. Fermentation of media containing 3 per cent dextrose, seeded with 5 per cent inoculum of X. campestris NRRL B-1459 and cultured aerobically at 28°C, is complete in 96 h. A light tan polymer is recovered in yields of 50 per cent, based on commercial dextrose, from the viscous fermentation broth by precipitation with methanol in the presence of an electrolyte. The viscosities of aqueous re-solutions containing 1 and 2 per cent of the polymer were 3,000 cP and 11,000 cP respectively.
Polyclonal and monoclonal antibodies for the specific detection of the herbicide acifluorfen and related compounds

Polyclonal and monoclonal antibodies reactive with acifluorfen (AF) were prepared by the immunization of, respectively, rabbits and mice with AF-bovine serum albumin conjugates. The reactivities of polyclonal antibody and three monoclonal antibodies (AF 9-1, AF 51-5 and AF 75-144) were examined in an indirect competitive enzyme-linked immunosorbent assay (C-ELISA). The polyclonal antibody reacted with AF at concentrations of 1.5 to 800 μg litre -1 , while the monoclonal antibodies reacted with AF at concentrations of 3 to 24 μg litre -1 for AF 9-1, 1.5 to 12 μg litre -1 for AF 51-5 and 12 to 48 μg litre -1 for AF 75-144. In the presence of up to 40% methanol in C-ELISA, the monoclonal antibodies, particularly AF 75-144, were less affected in their reactivities with AF than was the polyclonal antibody. Moreover AF 9-1 and AF 51-5 specifically reacted with acifluorfen-methyl and oxyfluorfen, while AF 75-144 reacted with chlornitrofen which did not react with the other antibodies. These results indicated that the antibodies are useful for the assay of AF and its related compounds.
Divergent Selection among Maize Seedlings for Nitrate Uptake

Selection applied to seedlings grown under controlled environmental conditions may contribute to plant improvement provided agronomic traits are well correlated to the seedling selection trait. The objective of this research was to utilize techniques for screening maize (Zea mays L.) seedlings for induced NO 3 uptake in order to evaluate direct and indirect effects of such selection on populations created
Pompe disease: genetics and management

Pompe disease (PD) is an autosomal recessive disease caused by partial or complete deficiency of the lysosomal hydrolase acid alpha-glucosidase, resulting in accumulation of glycogen in various tissues. It affects primarily the skeletal, smooth muscle and cardiac system. Pompe disease clinically presents as a continuum in its age of onset and multisystem involvement and is often fatal. Diagnosis can be difficult due to nonspecific phenotype of the disease. Enzyme replacement therapy (ERT) is the standard treatment for the disease since 2006. Although of considerable clinical benefit to some patients, there are significant limitations to ERT. Studies in novel therapeutic approaches show positive outcomes. In the context of therapeutic options, the earliest diagnosis and initiation of treatment can make a difference. Early identification through newborn screening and more effective therapies will hopefully lead to improved outcomes for patients with Pompe Disease.
Revision of genus Crassostrea (Bivalvia: Ostreidae) of Brazil

The Ostreidae are well known for their high intra-specific variation, which makes identification problematic. The present paper aims to provide a morpho-anatomical and taxonomic review of the Brazilian species of Crassostrea, as well as some congeneric species from other relevant areas. The Brazilian species are Crassostrea mangle sp.nov. and Crassostrea brasiliana. The exotic species Crassostrea gigas, cultivated in the southern region of the country, is also included in this study. Additional species are: Crassostrea virginica, from the Atlantic coast of the USA, the type species, and Crassostrea rhizophorae, a south-eastern Caribbean species that is supposed to occur in Brazil, but is here understood as a different entity endemic to that region. Taking into account their economic importance, the differentiation between these species is critical, and is essential for a better planning of production and preservation strategies. We point out the differences in almost all structures amongst these species, which are formally redescribed herein. The occurrence of the African species Crassostrea gasar in Brazil is established as false. The voucher specimens of previous studies responsible for this assumption were examined, evidencing a misidentification for Crassostrea brasiliana from an estuarine environment. The geographical distribution of the studied species is recognized as follows: Crassostrea rhizophorae in the south-east Caribbean Sea; Crassostrea mangle sp. nov. from Pará to the Santa Catarina, only in mangroves; Crassostrea brasiliana from Paraíba to Santa Catarina, both in rocky shores and mangroves; Crassostrea virginica ranges from the Atlantic coast of Canada to the Caribbean; and Crassostrea gigas originates from the Indo-Pacific, but has been introduced in southern Brazil. This paper also deals with conchological aspects of the endemic species Crassostrea praia, from south Lagoa dos Patos, Rio Grande do Sul; after a more detailed definition, and considering the deleterious effects of the nearby port and construction sites, it can be classified as an endangered species.
STRIDULATORY ORGAN AND ULTRASONIC EMISSION IN CERTAIN SPECIES OF PONERINE ANTS (GENUS: ECTATOMMA AND PACHYCONDYLA, HYMENOPTERA, FORMICIDAE)

ABSTRACT Five species of neotropical Ponerinae ants, Ectatomma permagnum Forel, E. quadridens Fabr. , E. ruidum Roger, E. tuberculatum Olivier and Pachycondyla apicalis Latreille, were studied. The genus Ectatomma, consisting of 14 species in the tropical forests of Central and South America, has been studied previously in relation to the stridulatory organ only. Stridulations were heard, in the four species considered in this paper, during artificial disturbance of individuals or of the whole colony; so the role of sound production during normal life is still uncertain. Pachycondyla apicalis, belonging to Central American forests, is occasionally present in cocoa and coffee plantations. The recordings made under laboratory conditions revealed the emission of pulse trains with very clear pulses extending in frequency to more than 75 kHz. The sounds recorded from the workers of the genus Ectatomma appeared homogeneous in their acoustic structure. They were typically emitted in long sequences and were made o.
