A comparative sequence analysis of the LEA (Late Embryogenesis Abundant (LEA)-like gene) intron fragment was performed in Pinus sibirica and P. pumila differing in geographic origin. It was demonstrated that in P. sibirica this fragment was represented by two types of PCR products, 224 and 202 bp in size. Similarly, in accessions of P. pumila, two PCR products of 224 and 159 bp in size were identified. Comparison of 224 bp fragments in P. sibirica and P. pumila showed that they differed in single nucleotide substitutions. Analysis of the intron fragment in a plant, which was characterized as an interspecific hybrid based on morphological characters, showed that it had fragments of 224 and 159 bp in size. The sequence of 224 bp fragment was similar to that of the corresponding fragment in P. sibirica. The structure of the short fragment was the same as the structure of the corresponding fragment in P. pumila. The data obtained are discussed in terms of the use of the sequences examined for species taxonomic classification and of an analysis of species hybridization.

Background: Scalp itch without evident cause is an uncomfortable symptom that annoys many people in life but lacks adequate attention in academic.
Aims: To investigate the relationship between scalp itching and microorganisms, and identify the key microbes and predicted functions associated with scalp itching, furtherly to provide useful targets for scalp itch solution.
Methods: We performed microbial comparison between 44 normal subjects and 89 subjects having scalp itching problem with un-identified origin based on 16S rRNA gene sequencing and ddPCR (digital droplet PCR), and identified itch relevant microbes and predicted functions.

Summary: Protein structure prediction aims to infer a protein's three-dimensional (3D) structure from its amino acid sequence. Protein structure is pivotal for elucidating protein functions, interactions, and driving biotechnological innovation. The deep learning model AlphaFold2, has revolutionized this field by leveraging phylogenetic information from multiple sequence alignments (MSAs) to achieve remarkable accuracy in protein structure prediction.

Objective: Previous observational studies suggest a potential link between gut microbiota, metabolites, and diabetic nephropathy. However, the exact causal relationship among these factors remains unclear.
Method: We conducted a two-sample bidirectional Mendelian randomization study using summary statistics from the IEU OpenGWAS Project database to investigate gut microbiota, metabolites, and diabetic nephropathy.
The plant shikimate pathway directs a significant portion of photosynthetically assimilated carbon into the downstream biosynthetic pathways of aromatic amino acids (AAA) and aromatic natural products. 3-Deoxy-d--heptulosonate 7-phosphate (DAHP) synthase (hereafter DHS) catalyzes the first step of the shikimate pathway, playing a critical role in controlling the carbon flux from central carbon metabolism into the AAA biosynthesis. Previous biochemical studies suggested the presence of manganese- and cobalt-dependent DHS enzymes (DHS-Mn and DHS-Co, respectively) in various plant species.

This study investigates the association of class II HLA alleles and the treatment outcome in children with steroid-dependent nephrotic syndrome (SDNS) who were treated with CYC. Methods A total of 77 children who were diagnosed with SDNS and had received CYC at least a year before were enrolled.
