Laju Pertumbuhan Zooplankton Diaphanosoma SP. Dengan Pemberian Pakan Kombinasi Fitoplankton Tetraselmis SP., Nannochloropsis SP. Dan Dunaliella SP. Di Laboratorium

Diaphanosoma sp. atau dikenal sebagai kutu laut, berpotensi sebagai pakan hidup untuk larva ikan dan udang karena siklus hidupnya relatif singkat sehingga memungkinkan untuk diproduksi secara masal. Untuk mengetahui pengaruh pemberian pakan kombinasi fitoplankton Tetraselmis sp., Nannochloropsis sp. dan Dunaliella sp terhadap laju pertumbuhan populasi Diaphanosoma sp. maka dilakukan serangkaian penelitian pada skala laboratorium dari bulan Maret sampai April 2013 di Laboratorium Pakan hidup Balai Besar Pengembangan Budidaya Laut Lampung dengan menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 5 ulangan. Hasil penelitian menunjukkan bahwa kepadatan, 1064 Ind/L dan pertumbuhan populasi tertinggi, 87,634 %, terdapat pada kultur yang diberi pakan 50 %Tetraselmis sp. + 25 % Nannochloropsis sp. + 25 % Dunaliella sp.. Hasil analisis proksimat menunjukkan bahwa pakan kombinasi Tetraselmis sp. 50 % + Nannochloropsis sp. 25 % + Dunaliella sp. 25 % memiliki kandungan gizi yang paling baik yaitu protein 44,46 %, karbohidrat 10,34 % dan lemak 4,21 %

Association between dopaminergic polymorphisms and borderline personality traits among at-risk young adults and psychiatric inpatients

Background: In the development of borderline personality disorder (BPD) both genetic and environmental factors have important roles. The characteristic affective disturbance and impulsive aggression are linked to imbalances in the central serotonin system, and most of the genetic association studies focused on serotonergic candidate genes. However, the efficacy of dopamine D2 receptor (DRD2) blocking antipsychotic drugs in BPD treatment also suggests involvement of the dopamine system in the neurobiology of BPD.Methods: In the present study we tested the dopamine dysfunction hypothesis of impulsive self- and other-damaging behaviors: borderline and antisocial traits were assessed by Structured Clinical Interview for Diagnosis (SCID) for DSM-IV in a community-based US sample of 99 young adults from low-to-moderate income families. For the BPD trait analyses a second, independent group was used consisting of 136 Hungarian patients with bipolar or major depressive disorder filling out self-report SCID-II Screen questionnaire. In the genetic association analyses the previously indicated polymorphisms of the catechol-O-methyl-transferase (COMT Val158Met) and dopamine transporter (DAT1 40 bp VNTR) were studied. In addition, candidate polymorphisms of the DRD2 and DRD4 dopamine receptor genes were selected from the impulsive behavior literature.Results: The DRD2 TaqI B1-allele and A1-allele were associated with borderline traits in the young adult sample (p = 0.001, and p = 0.005, respectively). Also, the DRD4 -616 CC genotype appeared as a risk factor (p = 0.02). With severity of abuse accounted for in the model, genetic effects of the DRD2 and DRD4 polymorphisms were still significant (DRD2 TaqIB: p = 0.001, DRD2 TaqIA: p = 0.008, DRD4 -616 C/G: p = 0.002). Only the DRD4 promoter finding was replicated in the independent sample of psychiatric inpatients (p = 0.007). No association was found with the COMT and DAT1 polymorphisms.Conclusions: Our results of the two independent samples suggest a possible involvement of the DRD4 -616 C/G promoter variant in the development of BPD traits. In addition, an association of the DRD2 genetic polymorphisms with impulsive self-damaging behaviors was also demonstrated. © 2010 Nemoda et al; licensee BioMed Central Ltd

Shortcuts in a Nonlinear Dynamical Braneworld in Six Dimensions

We consider a dynamical brane world in a six-dimensional spacetime containing a singularity. Using the Israel conditions we study the motion of a 4-brane embedded in this setup. We analyse the brane behaviour when its position is perturbed about a fixed point and solve the full nonlinear dynamics in the several possible scenarios. We also investigate the possible gravitational shortcuts and calculate the delay between graviton and photon signals and the ratio of the corresponding subtended horizons.Comment: 26 pages, 9 figures.

Perturbations of Gauss-Bonnet Black Strings in Codimension-2 Braneworlds

We derive the Lichnerowicz equation in the presence of the Gauss-Bonnet term. Using the modified Lichnerowicz equation we study the metric perturbations of Gauss-Bonnet black strings in Codimension-2 Braneworlds.Comment: 26 pages, no figures, clarifying comments and one reference added, to be published in JHE

The shortest cut in brane cosmology

We consider brane cosmology studying the shortest null path on the brane for photons, and in the bulk for gravitons. We derive the differential equation for the shortest path in the bulk for a 1+4 cosmological metric. The time cost and the redshifts for photons and gravitons after traveling their respective path are compared. We consider some numerical solutions of the shortest path equation, and show that there is no shortest path in the bulk for the Randall-Sundrum vacuum brane solution, the linear cosmological solution of Bin\'etruy, et al for $\omega = -1, -{2/3}$, and for some expanding brane universes.Comment: 20 pages, 7 figure
