Combined assessment of lysine and N-acetyl cadaverine levels assist as a potential biomarker of the smoker periodontitis.

Periodontitis is an inflammatory condition of supporting structures of teeth leading to attachment and bone loss. Cigarette smoking is the single most important and modifiable risk factor with 5 to 20-fold susceptibility for periodontal diseases. Reverse smoking is a peculiar habit of smoking where the lit end is kept inside the mouth, which is predominant in the northern coastal districts of Andhra Pradesh.

Bivoltine cocoon color sex-limited breeds of Bombyx mori (Lepidoptera: Bombycidae) show enhanced economic performance and fecundity following spermidine supplementation.

Sericulture has immense economic significance. Separating male and female silkworm pupae for egg production in grainage is a laborious task; hence, sex-limited breeds for cocoon color are advantageous for this process. The major constraint in sex-limited breeds is their low fecundity.

Thermal tolerance role of novel polyamine, caldopentamine, identified in fifth instar Bombyx mori.

Silkworms have limited ability to regulate their body temperature; therefore, environmental changes, such as global warming, can adversely affect their viability. Polyamines have shown protection to various organisms against heat stress. This study evaluated the qualitative and quantitative changes in heat-stressed Bombyx mori larvae polyamines.

Spermidine alleviates heat shock and promotes the growth of Bombyx mori.

Silkworms have limited ability to regulate their body temperature upon exposure to varying atmospheric temperatures. Environmental changes, such as global warming, adversely affect silkworm viability. Spermidine, a polyamine, protects various organisms against heat stress.

Dynamics of nuclear matrix attachment regions during 5 instar posterior silk gland development in Bombyx mori.

Background: Chromatin architecture is critical for gene expression during development. Matrix attachment regions (MARs) control and regulate chromatin dynamics. The position of MARs in the genome determines the expression of genes in the organism.

Nuclear matrix associated RNAs in posterior silk glands show developmental dynamics in Bombyx mori in 5th instar larvae.

Objectives: The nuclear matrix maintains and regulates chromatin structure. RNA is an integral component of the nuclear matrix and is essential to its structural maintenance. Bombyx mori is a major economic contributor in the sericulture industry and produces fibroin-the most important silk protein in its posterior silk glands during 5th instar larval stage.

Nuclear matrix associated RNA datasets of posterior silk glands of Bombyx mori during 5th instar larval development.

Objectives: Bombyx mori is the key contributor to industrial silk production. The maximum production of silk occurs during 5th instar. The posterior silk glands in the larvae are responsible for the production of the main component of silk fibre-fibroin.

16S rRNA sequence data of Bombyx mori gut bacteriome after spermidine supplementation.

Objectives: The silkworm Bombyx mori (B. mori) is an important domesticated lepidopteran model for basic and applied research. They produce silk fibres that have great economic value.

Knockdown of Broad-Complex Gene Expression of Bombyx mori by Oligopyrrole Carboxamides Enhances Silk Production.

Bombyx mori (B. mori) is important due to its major role in the silk production. Though DNA binding ligands often influence gene expression, no attempt has been made to exploit their use in sericulture.

Effect of polyamines on mechanical and structural properties of Bombyx mori silk.

Silkworm, Bombyx mori (B. mori) belongs to the Lepidoptera family. The silk produced from this insect, mulberry silk, gained lot of importance as a fabric.

Developmental proteome dynamics of silk glands in the 5th instar larval stage of Bombyx mori L (CSR2×CSR4).

Unlabelled: Bivoltine breed of Bombyx mori (B. mori), CSR2×CSR4 is an Indian high yielding silkworm strain. Silk gland proteome of this strain was not studied till now.

Spermidine enhances the silk production by mulberry silkworm.

Polyamines are ubiquitous low molecular weight polycationic aliphatic amines involved in diverse cellular processes. Spermidine (Spd), a polyamine, has been proved to be crucial for cell survival in various organisms. Our study reports the effect of Spd on the growth of Bombyx mori.

Transposable element 'roo' attaches to nuclear matrix of the Drosophila melanogaster.

The genome of eukaryotes is organized into structural units of chromatin loops. This higher order organization is supported by a nuclear skeleton called the nuclear matrix. The genomic DNA associated with the nuclear matrix is called the matrix associated region (MAR).

The effect of bovine milk on the growth of Bombyx mori.

Bombyx mori L. (Lepidoptera: Bombycidae) is a well-studied Lepidopteran model system because of its morphology, life cycle, and economic importance. Many scientists have placed importance on enhancing the economic traits of B.

AAGAG repeat RNA is an essential component of nuclear matrix in Drosophila.

Eukaryotic nucleus is functionally as well as spatially compartmentalized and maintains dynamic organization of sub-nuclear bodies. This organization is supported by a non-chromatin nuclear structure called the nuclear matrix. Although the precise molecular composition and ultra-structure of the nuclear matrix is not known, proteins and RNA molecules are its major components and several nuclear matrix proteins have been identified.

Polymorphism and epitope sharing between the alleles of merozoite surface protein-1 of Plasmodium falciparum among Indian isolates.

Background: The C-terminal region of merozoite surface protein-1 (MSP-1) is one of the leading candidates for vaccination against the erythrocytic stages of malaria. However, a major concern in the development of MSP-1 based malaria vaccine is the polymorphism observed in different geographical Plasmodium falciparum isolates. To explore whether the sequence heterogeneity of PfMSP-1 leads to variation in naturally acquired anti-MSP-119 antibodies, the present study was undertaken to study PfMSP-119 sequence polymorphism in malaria-endemic villages in eastern India and also carried out a competition enzyme-linked immunosorbent assay using three PfMSP-119 variant forms.
