While the review is extremely thoughtful and reflects the deep insights of the author into the field, the two assumptions cited above need be challenged. We fully agree with Hadders-Algra that AA has its own potent and biologically important functions, which makes it unwise to support interventions markedly reducing tissue levels of AA, but we do not have evidence for any such risk with a DHA s...

Using zebrafish intestinal fatty acid-binding protein 2 (FABP2) mRNA sequence as the initial query probe, four highly homologous Paralichthys olivaceus EST sequences were retrieved from Genbank database. The assembled full-length cDNA contains the open reading frame of P. olivaceus FABP2 gene, which was validated by subsequent RT-PCR cloning. In the coding region, the average GC content is 56%,...

Nutritional value of freshwater mesozooplankton, fatty acid (FA) and amino acid (AA) compositions were determined in the middle of each season for a one-year period from May 2009 to February 2010 in Hanna Dam Lake, Isfahan, Iran. FA and AA composition significantly (P<0.05) varied in relation to the seasonal changes of water quality, phytoplankton and zooplankton community. The content of satur...

The Cobb × Cobb 500 slow-feathering male is a fast early-growth broiler grown under variable feeding programs and amino acid (AA) densities. An experiment was conducted using diets with increased ideal protein densities in a feeding program of 1 to 7 d, 8 to 21 d, 22 to 35d, and 36 to 42 d. Diets had ratios between essential digestible (D) AA and DLys (DAA:DLys) as follows: TSAA, 75%; DThr, 65%...

Attachment of HeLa cells to gelatin induces the release of arachidonic acid (AA), which is essential for cell spreading. HeLa cells spreading in the presence of extracellular Ca2+ released more AA and formed more distinctive lamellipodia and filopodia than cells spreading in the absence of Ca2+. Addition of exogenous AA to cells spreading in the absence of extracellular Ca2+ restored the format...

Third-cutting alfalfa with 37% DM was ensiled untreated or treated with either 2.8 g of formic acid/100 g of DM or .31 g of formaldehyde/100 g of DM and fed to lactating dairy cows in two experiments. Silage treated with formic acid had the lowest pH and concentrations of NPN, NH3, and total free AA. Both treatments decreased rumen in vitro protein degradability but did not affect in vitro rume...

Phenylketonuria (PKU) is caused by deficient activity of the enzyme phenylalanine hydroxylase, needed to convert the essential amino acid (AA) phenylalanine (phe) to tyrosine. In order to prevent neurological damage, lifelong adherence to a low-phe diet that is restricted in natural foods and requires ingestion of a phe-free AA formula to meet protein needs is required. The goal of nutritional ...

During pathophysiological muscle wasting, a family of ubiquitin ligases, including muscle RING-finger protein-1 (MuRF1), has been proposed to trigger muscle protein degradation via ubiquitination. Here, we characterized skeletal muscles from wild-type (WT) and MuRF1 knockout (KO) mice under amino acid (AA) deprivation as a model for physiological protein degradation, where skeletal muscles altr...

This study investigated the effects of supplementation of various sources of Met and Lys on nutrient digestion, N utilization, and duodenal AA flows in growing goats. Four 4-mo-old Liuyang Black wether goats were used in a 4 x 4 Latin square experiment and were assigned to 4 dietary treatments: (1) control, (2) control + lipid-coated Met-Zn chelate and Lys-Mn chelate (PML), (3) control + Met-Zn...

background bipolar disorder is a biological brain disorder which is associated with debilitating fluctuation in mood and adverse effects on patients, their families and society. the importance of genetics and its role in bipolar disorder is a controversial issue to discuss. evidence indicates a relation between the risk of bipolar disorder and specific genes. amongst the genes whose role has be...
