Salminus Brasiliensis

Salminus brasiliensis is a migratory fish that has attracted considerable interest for aquaculture. Several procedures for induced spawning are known; however, there is a lack of protocol which enables the use of cryopreserved semen. Therefore, this study was conducted to investigate the use of cryopreserved semen using different volumes of cryopreserved semen relative to oocytes, different activators solutions and different maintenance time during the fertilization of dourado to evaluate the impact of these parameters on the fertilization rate. The semen was collected, cryopreserved in 0.5mL straws and stored in a dry shipper. Oocytes samples were fertilized according to each treatment. The different activator solutions and the contact times of the gametes with activators affected significantly the fertilization rates, which ranged between 13.4 and 27.8%, while fresh semen fertility rate was 80.8%. The relationship between oocyte and cryopreserved semen was significant, being the best ratio 0.05mL of cryopreserved semen per 10g of oocytes, while upper or lower volumes promoted a reduction in fertilization. The use of cryopreserved semen was effective to fertilize S. brasiliensis oocytes, however produced lower fertility rate than fresh semen

<p><strong>BACKGROUND: </strong>Examination time is a key factor determining the relative value of clinical physicians’ examination and care quality. Whereas commitment <strong>‎</strong>to standard prescription principles by physicians increases the likelihood of proper treatment, its effectiveness and patients’ improvement. This study aimed to determine the relationship between outpatients’ examination time and physicians prescribing quality in teaching hospitals of Ahvaz.<strong></strong></p><p><strong>METHODS: </strong>This cross-sectional study was conducted in 550 outpatients who visited teaching hospitals of Ahvaz in 2015.<strong> </strong>The quality of the prescriptions was assessed by WHO checklist<strong>.</strong> Each prescription was scored with a score range from 0 to 21, they were divided into four equal score categories including low (0–5.25), low intermediate (5.26–10.5), high intermediate (10.5–15.75) and good (15.76–21) and using correlation and regression was analyzed.</p><p><strong>RESULTS:</strong> The total mean of examination time and commitment to prescription principles was 4.88±0.12 min and 15.92±1.14, respectively. Correlation coefficients between outpatients’ examination time and dimensions of “legibility”, “pharmaceutical form” and “medical orders”, and the total quality of prescription were significant (p˂0.005). The relationship between examination time and prescription quality confirmed with the fitting linear regression model. Increase per minute in patient’s examination by a physician, which is about 0.33 points, was added to the basic quality scores of prescription.</p><p><strong>CONCLUSION: </strong>There was<strong> </strong>a relationship between Examination time and dimensions of legibility, pharmaceutical form, and medical order. Considering commitment <strong>‎</strong>to standard prescription principles,<strong> </strong>examination time, which was declared by the Health Sector Evolution Guideline, improve physicians’ prescription quality and quality of provided services of hospitals. Therefore, providing an internet schedule for examination will be extremely helpful in organizing physicians’ examination.</p>

The Relationship

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.

Abstract Cognitive Gadgets offers a new, convincing perspective on the origins of our distinctive cognitive faculties, coupled with a clear, innovative research program. Although we broadly endorse Heyes’ ideas, we raise some concerns about her characterisation of evolutionary psychology and the relationship between biology and culture, before discussing the potential fruits of examining cognitive gadgets through the lens of active inference.

Picture Element

It is well known that a large flux of electrons must pass through a specimen in order to obtain a high resolution image while a smaller particle flux is satisfactory for a low resolution image. The minimum particle flux that is required depends upon the contrast in the image and the signal-to-noise (S/N) ratio at which the data are considered acceptable. For a given S/N associated with statistical fluxtuations, the relationship between contrast and “counting statistics” is s131_eqn1, where C = contrast; r2 is the area of a picture element corresponding to the resolution, r; N is the number of electrons incident per unit area of the specimen; f is the fraction of electrons that contribute to formation of the image, relative to the total number of electrons incident upon the object.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
