In this study five species of probiotic bacillus as bacterial blend under the commercial title of Protexin aquatic were used for bioencapsulation of Artemia urmiana (Gunther, 1899). This experiment was conducted in a completely random design. A. urmiana naupli I was used as a vector to carry probiotic bacillus to digestive tract of Huso huso (Linnaeus, 1758) larvae. Nauplii with three concentrations of bacteria, 1×10 5, 2×10 5 and 3×10 5 bacteria per milliliter in suspension of broth for 10 hours were bioencapsulated and beluga larvae were fed by them. Beluga larvae were fed 50 percent of their body weight for 6 times a day. The control treatment was fed by unbioencapsulated artemia nauplii. The results indicated that the probiotic bacillus could influence on growth and feeding parameters in beluga larvae. The final body weight and specific growth rate (SGR) for weight in experimental treatments had significant difference in comparison to control treatment (P<0.05). In experimental treatments the Food efficiency was increased significantly in comparison with control. The probiotic bacillus had significant positive effects on conversion efficiency ratio (CER), Daily growth coefficient (DGC) and average weight gain (AWG) in comparison to control treatment (P<0.05). Also the relative food intake (RFI) significantly decreased (P<0.05) while Protein gain (PG) and Energy retained as protein (PD.KJ day -1) significantly increased (P<0.05). Source

The objective of the present study was to investigate the polymorphism of prolactin promoter and cytosolic phosphoenol pyruvate carboxykinase (PEPCK-C) intron 3 to exon 3 regions, and its association with economic traits in native fowl of Yazd province. These traits consisted of body weight at 8 (BW8) and 12 (BW12) weeks of age, age at sexual maturity (ASM), weight at sexual maturity (WSM), mean egg weight at 28, 30, and 32 weeks (MEW), and the number of eggs during the first 12 weeks of laying period (EN). Blood samples were collected from 159 pedigreed fowl at native fowl breeding center of Yazd province, and DNA was extracted from the samples according to salting out protocol. PCR amplification together with restriction fragment length polymorphism was used to identify different genotypes of prolactin and PEPCK-C genes. The effect of prolactin genotypes on economic traits was analyzed using general linear model. A 24-bp indel (insertion or deletion) at nucleotide position (np) 358 was identified, but no polymorphism was found for PEPCK-C. Based on our results, the frequency of I and D alleles were 0.761 and 0.239, respectively. Frequencies of II, ID and DD genotypes were 0.566, 0.389 and 0.044, respectively. Genotypes II and ID were significantly associated with incresased EN (P<0.01). Meanwhile, the genotypes of the 24-bp indel site were not significantly associated with BW8, BW12, ASM, WSM and MEW (P> 0.05). The results of current study showed that using information of genes related to egg production could be used to improve the performance of native fowl of Yazd province. Source

An efficient synthesis of 2-hydroxy-3-[2-oxo-2-phenylethylidene]-2-phenyl- 2, 3-dihydro-4 H-furo[3, 2-c] chromene-4(2H)-one is described. This involves the reaction between dibenzoylacetylene and 4-hydroxycoumarine in the presence of NaH (10mol %) in nearly quantitative yield. Treatment of this heterocyclic system with trimethyl chlorosilane in CHCl3 leads quantitatively to 4-oxo-3-[-[2-oxo-2-phenylethylidene]-2-phenyl-3H,4H-furo[3,2-c] chromene-1-ium chloride. Direct addition of nucleophiles, such as alcohols, amines or trialkyl phosphites to this salt in water as the solvent produces functionalized 2-phenyl-4H-f-furo[3,2-c] chromen derivatives in excellent yields. © Springer Science+Business Media B.V. 2010.

In this study we generally describe the hole-in-head disease and introduce a new method of treatment that called cupping. Cupping is important and old treatment for specific diseases in human, used by Iranian and Chinese medicinists in the past. This disease, often called hexamitiasis, is caused by a member of the genus Hexamita or Spironucleus. This parasite has two forms of infection one of them is external and cause hole-in-head disease and the other form is internal that cause intestinal problems. Hole-in-head disease cause death in flower horn fishes which are expensive and very popular members of Cichlidae family. Flower horn fish is a genetically improved hybrid between Amphilophus labiatus and Amphilophus trimaculatus. This simple method of cupping combined with stress factors removal was applied by us for the treatment of external hexamitiasis resulting in more than 50% cases of fish health recovery. The first signs of heath in treated specimens become visible after 4-6 days of treatment. Source

A straightforward and efficient method for the synthesis of 1,2-dihydroisoquinolines via a one-pot, three-component reaction of isoquinoline, activated acetylenes, and NH-acids in water at 70°C without using any catalyst is reported. The method offers several advantages including high yields of products and an easy workup procedure.. © 2011 HeteroCorporation. Source
