This research investigates the bacterial diversity associated with lung cancer through metagenomic analysis. The study utilized metagenomic data from the European Nucleotide Archive (ENA), specifically accession number PRJNA592147, examining ten FASTQ files representing two lung cancer samples. The 16S lung cancer metagenome was sequenced using Illumina MiSeq paired-end technology, with data processing conducted on the Galaxy server. Data quality was enhanced through FastQC quality control and Trimmomatic sequence trimming. Kraken 2 was employed for taxonomic classification and bacterial community abundance assessment, while the Krona tool facilitated data visualization. The analysis revealed three notable bacterial species: Mycolicibacterium chubuense, Arthrobacter ramosus, and Streptosporangium longisporum. M. chubuense, a member of the Mycobacteriaceae family, is characterized as a non-motile, spore-free bacterium that thrives in various media at 37°C. A. ramosus, belonging to the Micrococcaceae family, is an obligate aerobe that flourishes in multiple culture media at temperatures ranging from 28–30°C. S. longisporum, part of the Streptosporangiaceae family, forms sporangia and exhibits ideal progress at 30°C in specific media. The identification of these bacteria in lung cancer samples suggests their potential involvement in the disease's development and progression. This investigation offers insights into the microbial landscape associated with lung cancer, potentially contributing to a well understanding of the disease's etiology and the development of novel therapeutic approaches. Further research is required to validate these results and elucidate the mechanisms connecting these bacteria to lung cancer.

The performance of an electrospun biomedical construct is determined less by the spinning parameters than by the polymer from which it is made, yet polymer selection in the literature is usually justified by precedent rather than by a systematic comparison. This review compares eight fibre-forming polymers used in electrospun biomedical constructs — four synthetics (poly (lactic acid), poly (glycolic acid), polycaprolactone, poly (ethylene terephthalate)) and four naturals (chitosan, collagen, alginate, silk fibroin) — across four property groups: thermal and processing behaviour, degradation kinetics and products, biological interaction, and solvent requirements. Reported values are collected in a common format and three derived indicators are introduced: the thermal processing window, the ratio of resorption time to the typical healing period of the target tissue, and the presence or absence of cell-adhesion motifs. The analysis shows that the synthetic polyesters offer a wide and reproducible processing window but a fixed degradation rate and acidic degradation products, whereas the natural polymers offer favourable biological interaction but, with one exception, either degrade too quickly or cannot be spun without a carrier. Silk fibroin is identified as the only polymer whose degradation rate spans the full range required by the reported applications — from weeks to a year — while its degradation products remain metabolisable, and the practical cost of this advantage is quantified as the carrier fraction required for stable jet formation.

Distribution partners can receive timely information yet fail to agree on a response or implement it before service deteriorates. This paper develops Distributed Adaptive Capacity (DAC) to explain that conversion problem. An integrative conceptual synthesis connects organizational information processing, ecosystem coordination, supply-chain resilience and configurational theory. DAC comprises digital permeability, orchestration intensity and reconfiguration velocity. These capabilities are proposed to influence detection, alignment and execution delays, respectively, within an independently specified adaptation window. Five diagnostic archetypes and seven proposition families distinguish the framework's definitions from relationships requiring empirical testing. A documentary illustration of Pak Elektron Limited examines the evidential limits of applying DAC to public disclosures. Dealer-share dissimilarity is approximately 0.216 against four-province population exposure and 0.234 against an urban-population proxy. Commercial and service networks also have different provincial distributions. These calculations describe network structure; they neither measure DAC nor establish its effects. The paper supplies a twelve-indicator protocol, separates missing evidence from low capability, and identifies requirements for event-based validation against established supply-chain constructs. Its contribution is a bounded account of how information becomes coordinated operational change across organizational boundaries. Whether the proposed capability profile improves prediction beyond existing measures remains an open empirical question.

Non-woven nanofibrous materials produced by electrospinning are increasingly used in wound management, tissue engineering, controlled drug delivery and cosmetic products. Although the number of reported formulations grows rapidly, the link between the intended clinical or cosmetic function and the material properties that must be engineered to achieve it is rarely stated explicitly, which makes polymer selection largely empirical. This review organises the reported evidence into a function–property–polymer map. Four application groups are analysed: therapeutic dressings, cell substrates for tissue engineering, drug-delivery matrices and cosmetic delivery films. For each group the governing material properties are identified — inter-fibre porosity and specific surface area, fibre diameter and its distribution, fibre orientation, degradation rate and its controllability, surface chemistry and residual-solvent toxicity. It is shown that fibre diameter and degradation controllability are the two properties that appear in all four application groups, whereas fibre orientation is decisive only for anisotropic tissue constructs. On this basis a set of selection criteria is proposed, and silk fibroin is identified as the natural fibre-forming polymer that satisfies the largest number of criteria simultaneously, principally because its degradation rate can be tuned through the β-sheet content without changing the polymer chemistry. The limitations of the current evidence base — the scarcity of quantitative structure–function correlations and of residual-solvent reporting — are discussed.
