Pengaruh Pemberian Jenis Pakan Yang Berbeda Terhadap Mutu Gonad Calon Induk Ikan Ingir-ingir (Mystus Nigriceps)

The research was conducted from January to March 2016 at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Science University of Riau Pekanbaru. The aim of this research was to evaluate suitable feed for the maturation of the gonad of bagrid catfish (Mystus nigriceps) reared with different feeding treatment (Commercial feed; cookle meat; soilworm(annelid) and chopped fresh fish. The research method used was Completely Randomized Design (CDR) with four treatments and three replications. The result showed that chopped fresh fish (Poecilia reticulata) and commercial dry food were the best food for maturating the fish gonad of bagrid catfish (Mystus nigriceps). Total fish reached matured stage IV was 16 fish (88,89%), gonad somatic index 9,06 %, relative fecundity 835 eggs/g fish, egg diameter 0,85 mm. The temperature range from 28 – 310C, pH 5 – 6, DO 5,7 – 6,8 ppm

Soliton-potential interaction in the nonlinear Klein-Gordon model

The interaction of solitons with external potentials in nonlinear Klein-Gordon field theory is investigated using an improved model. The presented model has been constructed with a better approximation for adding the potential to the Lagrangian through the metric of background space-time. The results of the model are compared with another model and the differences are discussed.Comment: 14 pages,8 figure

Baseline and On-Treatment High-Density Lipoprotein Cholesterol and the Risk of Cancer in Randomized Controlled Trials of Lipid-Altering Therapy

ObjectivesWe sought to examine the relationship between high-density lipoprotein cholesterol (HDL-C) levels and the risk of the development of cancer in large randomized controlled trials (RCTs) of lipid-altering interventions.BackgroundEpidemiologic data demonstrate an inverse relationship between serum total cholesterol levels and incident cancer. We recently reported that lower levels of low-density lipoprotein cholesterol are associated with a significantly higher risk of incident cancer in a meta-analysis of large RCTs of statin therapy. However, little is known about the relationship between HDL-C levels and cancer risk.MethodsA systematic MEDLINE search identified lipid intervention RCTs with ≥1,000 person-years of follow-up, providing baseline HDL-C levels and rates of incident cancer. Using random-effects meta-regressions, we evaluated the relationship between baseline HDL-C and incident cancer in each RCT arm.ResultsA total of 24 eligible RCTs were identified (28 pharmacologic intervention arms and 23 control arms), with 625,477 person-years of follow-up and 8,185 incident cancers. There was a significant inverse association between baseline HDL-C levels and the rate of incident cancer (p = 0.018). The inverse association persisted after adjusting for baseline low-density lipoprotein cholesterol, age, body mass index (BMI), diabetes, sex, and smoking status, such that for every 10-mg/dl increment in HDL-C, there was a 36% (95% confidence interval: 24% to 47%) relatively lower rate of the development of cancer (p < 0.001).ConclusionsThere is a significant inverse association between HDL-C and the risk of incident cancer that is independent of LDL-C, age, BMI, diabetes, sex, and smoking

The Effect of Light Difference and Feed That Provided to Improve the Quality of Fish Colour, Growth and Survival Rate for Platy Fish (Xiphophorus Helleri)

This study was conducted from May 16 until July 4 2016 in the fish hatchery and breeding laboratory, Fisheries and Marine Sciences Faculty of Riau University. The purpose of this study was to determine the influence of light (dark, light, sunlight) and the type of feed (Tubifex sp and pellet) on colour quality, growth and survival rate Platy fish (Xiphophorus helleri). Experimental method used in this study was completely randomized design with factorial 3 x 2 x 3. The first factor was light consist of dark light, bulb light and sun, while the second factor was type food (Tubifex sp. feed and TAKARI pellet) with three replications. The fish was reared in 3 L aquarium those reared with dark and bulb light were dow inside and that with sun light was dow outside.The result showed that the best treatment from that all is to giving sunlight and feed the platy with Tubifex sp and the sunlight given TAKARI Pellet feed can improve the colour quality till level 30 of sunlight level. Treatment with feed Tubifex sp provide the absolute best length of 2.40 cm and the fish weights from the absolute best in sun light treatments with feed Tubifex sp can increase to 0.34 g. The Best survival rate in treatment without light / dark, sunlight, lamplight with feed Tubifex sp and sunlight, lamplight with Pellet feed TAKARI of 94.44%. and for the Results of water quality measurements: temperature ranging from 26.1 to 31.3 ° C, pH range between 6.6 to 7.3 and DO ranged from 4.2 to 6.3 ppm
