Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

A whole food, plant-based diet reduces amino acid levels in patients with metastatic breast cancer

open access: yesCancer & Metabolism
Background Amino acids are critical to tumor survival. Tumors can acquire amino acids from the surrounding microenvironment, including the serum. Limiting dietary amino acids is suggested to influence their serum levels.

Effect of cattle breed on muscle protein quality

open access: yesCzech Journal of Animal Science
The aim of the study was to compare the muscle protein quality in the m. longissimus, pars thoracis of bulls of the Aberdeen Angus (AA) and Czech Fleckvieh (CF) breeds reared under identical conditions within an extensive pasture-based system.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Elevated amniotic fluid amino acid levels in fetuses with gastroschisis

open access: yesBrazilian Journal of Medical and Biological Research, 2006
Our objective was to measure maternal plasma and amniotic fluid amino acid concentrations in pregnant women diagnosed as having fetuses with gastroschisis in the second trimester of pregnancy.

The Role of Proline and Certain Non-Essential Amino Acids in Chick Nutrition

open access: yesPoultry Science, 1962
Abstract THE relative abundance of serine, alanine, aspartic acid and proline in natural proteins has made it difficult to determine their role in chick nutrition when diets containing intact proteins are employed. The dispensable nature of these amino acids in a crystalline amino acid diet was reported by Almquist and Grau (1944).

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Amino Acid Composition of Tamarind Fruit Growing Wild in Oyo Town

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2013
Tamarind ( Tamarindus indica L.) fruit grows wild in some parts of the savannah region of Nigeria. The fruit is grossly underutilised in Nigeria, despite its invaluable contribution to the food security and economy of some Asian countries.

Effect of essential and non-essential amino acid supplementation in canine nutrition

open access: yesRevista de Investigaciones Veterinarias del Perú, 2023
The study evaluated the effect of a nutritional supplement (composed of the 10 essential and eight non-essential amino acids) and a commercial vitamin supplement on body weight and body condition of 44 malnourished dogs (body condition 1 and 2). The animals were weighed and evaluated on days 1, 7 and 14 of treatment.
