Eggs And Larvae

The importance of egg and larval mortality in the determination of year-class strength was discussed at a colloquium at La Jolla, California in 1975 (see Hunter, 1976). In addition to the obvious effects of starvation, predation and disease, pollution by such substances as copper is an important factor affecting viability. The copper concentration in sea water is generally about 1–2,µ/l. Chester & Stoner (1974), in a comprehensive survey, found an average copper concentration of 0.8µ/l in the open ocean and 0.9 µg/l nearer the shore. In British waters Preston et al. (1974) reported a range of 1.1–1.6 µg/l and Portmann (1972a) found a range of 1–20 µg/l with the possibility of 1000 µg/l near sea-bed copper deposits.

The Village

The development of energy services for the 40% of the world’s population currently living in energy poverty is a challenging design problem. There are competing and often conflicting objectives between stakeholders from global to user viewpoints, and the confounding effects of real-world performance, rebound, and stacking of technologies makes the determination of optimal strategies for off-grid village energy complicated. Yet there are holistic and lasting solutions that can adequately address the technical, social, economic, and environmental constraints and satisfy the goals of all stakeholders. These solutions can be better identified by systematically considering five major qualitative and quantitative outcomes including 1) energy access and efficiency, 2) climate benefits, 3) health impacts, 4) upfront and recurring economic and opportunity costs, and 5) quality of life for the user in terms of several metrics. Beginning with a comprehensive survey of energy uses in a village and current and potential technological options to meet those needs, this article proposes a methodology to identify and quantify these five outcomes for various intervention scenarios. These evaluations can provide a better understanding of the constraints, trade-offs, sensitivity to various factors, and conditions under which certain designs are appropriate for the village energy system. Ultimately a balance of all five objectives is most likely to result in equitable, user-driven, and sustainable solutions.

Primary hyperparathyroidism is a socially significant problem due to the fact that the analysis of blood calcium in Russia is not a routine biochemical test, and diagnosis is carried out at the stage of irreversible complications. So, a patient addressed to our clinic which had a clinical picture of hyperparathyroidism complications over time. In the hospital diagnostic studies were carried out, including, first of all, a determination of calcium in blood, followed by more comprehensive survey, on the basis of which hyperparathyroidism has been confirmed. An adenoma of the left lower parathyroid gland was found by the method of topical diagnosis (ultrasound of the parathyroid glands and scintigraphy with Tc-99m-technetril). After the surgical treatment a level of calcium and a level of PTH have declined significantly. The combination of calcium and vitamin D supplementation was prescribed about intensive saturation therapy was needed with intense post-operative hyperparathyroidism. Given the existence of osteo-visceral complications by hyperparathyroidism, at the moment the patient needs a long rehabilitation course. This case shows that in order to avoid late diagnostics, it seems necessary to determine the level of calcium for routine. Therefore, it is possible to prevent the development of complications of the disease and the disability of patients.

AbstractUsing infrared speckle imaging techniques, we have completed a comprehensive survey of all northern (δ ≥ −25°) M dwarfs within 8 parsecs for low mass companions. Of the 74 targets searched, six new companions were found. Included in the final census are four objects orbiting their primaries at sub-arcsecond separations which have masses near 80 Jupiters, making them viable brown dwarf candidates. Three of these — LHS 1047B, GL 623B and G 208-44B — are the faintest red objects for which masses have been determined and represent the limit of our current knowledge about the faint end of the mass-luminosity relation.The complete sample includes 99 members, and under further analysis reveals fundamental facts about the red dwarf population that were unknown until the present study: 1) 30-40 % of M dwarf primaries have companions, 2) more companions are found orbiting 1-10 AU from the primary than in any other decade interval, and 3) there are 50% fewer red dwarfs known in the more distant half of the survey volume, presumably because the parallax and proper motion surveys are incomplete.In addition, we find that the infrared luminosity function (LF) is fiat or rising toward the end of the main sequence, while the visible LF may be flat, and we illustrate that the determination of an accurate LF is critically sensitive to the resolution of binaries. A better description of the stellar population, the mass function, is found to be undoubtedly rising to the stellar/substellar break. Finally, we have developed a much-needed mass-luminosity relation for stars of mass 1.2 to 0.08 M⊙, and using these relations find that the M dwarfs contribute ~0.2 M⊙/pc3 to the galactic mass.

The aim: to investigate the copper content in blood serum of children with different short stature types. Materials and methods: In the first stage, a comprehensive survey of 258 school children aged 7-11 was carried out in Chernivtsi to assess the prevalence of short stature children of school-age. In the second stage, a comparative study of 42 children aged 3 to 15 years with different types of short stature was conducted. Research: anthropometry, determination of growth hormone, TSH, IGF-1, and copper level in blood plasma. Results: The largest growth rate in children with somatotropic insufficiency, the syndrome of a biologically inactive growth hormone ranged from 4.1 cm/year to 1.6 cm/year, the ones with a family constitutional low-growth – from 5.7 cm/year to 3.3 cm/year. In 57 cases, that makes 1% of children with short stature, the blood plasma level of copper made less and rated 0.89 ± 0.04 μg / ml, which is believed to be lower (pу0,001) the average copper in children of the control group – 1.07 ± 0.02 μg / ml. Indices of copper in blood plasma in children with somatotropic insufficiency were the lowest and averaged 0.75 ± 0.03 μg / l, p<0.05. Conclusions: The lack of copper in the blood plasma is observed in most children with short stature, which indicates the need for appropriate correction.

The true picture of the severity and the degree of central nervous system (CNS) in children of the first months of life, doesn&#180;t is always reflected. The outcome of the disease, including unfavorable, is obvious only to the 9-12 months of age due to the features that are assessed as the phenomena of self-defense. A lot of attention in modern Russian and foreign literature is given to the biochemical risk factors for the development of various diseases and their complications, in particular the indicators of oxidative stress, lipid peroxidation, oxidative modification of proteins and antioxidant defense, neurospecific factors involved in the processes of maturation, differentiation and maintain the viability of brain neurons. However, the diagnostic potential of the investigated markers in children didn&#180;t revealed. Purpose of this study is determination of markers of neurological deficits in infants on the basis of neurotrophic factors, indicators of oxidative stress and endothelial dysfunction. Materials and methods. Comprehensive survey of 134 children (61 boys and 73 girls) aged from 0 to 9 months was carried out with the assessment of neurological status and biochemical markers. Results of study. The first component of the nervous tissue of the brain, responding to hypoxia, is microglial environment, which is caused by the growth of lesions S100- protein (i.e., the neuron at the stage of 0-1 months didn&#180;t been metabolic changes - this is evidence of low levels of SOD and MDA).
