The following changes were found in children in the minimal cerebral dysfunction: the hypoaminoacidemia and hypoaminoaciduria with decrease of glutamate and aspartate, their amides, methionine and serine in the blood and urine; decrease of lysine, taurine, tyrosine, catecholamines and serotonin in the blood; increase of GABA and glycine in the blood; increase of xanthurenate, proline and cysteine in the urine. The ratio excitatory/inhibitory mediatory amino acids decreased significantly. The ratio essential/nonessential amino acids and concentrations of amino acids, transporting by x-AG, beta and A/ASC systems, decrease in the blood; majority of transporting systems in the kidney functions augmently. Disturbances of amino acids metabolism disappear or decrease in successful treatment.

Significant progress has been made in cancer therapy with protein-based nanocarriers targeted directly to surface receptors for drug delivery. The nanocarriers are a potentially effective solution for the potential drawbacks of traditional chemotherapy, such as lack of specificity, side effects, and development resistance. Peptides as nanocarriers have been designed based on their biocompatible, biodegradable, and versatile functions to deliver therapeutic agents into cancer cells, reduce systemic toxicity, and maximize therapy efficacy through utilizing targeted ligands such as antibodies, amino acids, vitamins, and other small molecules onto protein-based nanocarriers and thus ensuring that drugs selectively accumulate in the cancer cells instead of healthy organs/drug release at a target site without effects on normal cells, which inherently caused less systemic toxicity/off-target effect.

Antibodies are extensively used in biomedical research, clinical fields, and disease treatment. However, to enhance the reproducibility and reliability of antibody-based experiments, it is crucial to have a detailed understanding of the antibody's target specificity and epitope. In this study, we developed a high-throughput and precise epitope analysis method, DECODE (Decoding Epitope Composition by Optimized-mRNA-display, Data analysis, and Expression sequencing).

Objectives: Pancreatic cancer, a highly invasive and prognostically unfavorable malignant tumor, consistently exhibits resistance to conventional chemotherapy, leading to substantial side effects and diminished patient quality of life. This highlights the critical need for the discovery of novel, effective, and safe chemotherapy drugs. This study aimed to explore bioactive compounds, particularly natural products, as an alternative for JAK2 protein inhibitor in cancer treatment.

A novel bacterium, designated 19SA41, was isolated from the air of the Icelandic volcanic island Surtsey. Cells of strain 19SA41 are Gram-stain-negative, strictly aerobic, non-motile rods and form pale yellow-pigmented colonies. The strain grows at 4-30 °C (optimum, 22 °C), at pH 6-10 (optimum, pH 7.

RNA G-quadruplexes (rG4s), the four-stranded structures formed by guanine-rich RNA sequences, are recognized by regions in RNA-binding proteins (RBPs) that are enriched in arginine-glycine repeats (RGG motifs). Importantly, arginine and glycine are encoded by guanine-rich codons, suggesting that some RGG motifs may both be encoded by and interact with rG4s in autogenous messenger RNAs (mRNAs). By analyzing transcriptome-wide rG4 datasets, we show that hundreds of RGG motifs in humans are at least partly encoded by rG4s, with an increased incidence for longer RGG motifs (~10 or more residues).
