The pulp and paper industry, a major global sector, supports economies and jobs while contributing to various products. While providing valuable products, and despite Best Available Techniques (BAT) being used, managing wastewater effectively remains a key area for developing technologies and alternatives for environmental protection. Activated sludge (AS) systems are commonly used for effluent treatment, where microorganisms composition influences reactor efficiency.

Colon neoplasia is one of the major malignancies in industrialized countries due to their Western-style food habits. It accounts for more than 50% of the population developing adenomatous polyps by the age of 70 years, but 10% of cancers in developed countries. The aim of this study was to evaluate the pathological role of the C-X-C chemokine receptor type 4/stromal-derived factor 1 axis (CXCR4-SDF-1 axis), and the inhibitory molecules PD-1 and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) in postoperative colon cancer patients undergoing treatment with chemotherapy (oxaliplatin and capecitabine) and estimate the correlation between these studied factors to deeply understand the basic mechanisms and potential diagnostic or therapeutic effects.

Designing ideal human biomonitoring studies involves the selection of reliable markers of exposure in adequate biological matrix. Besides conventional matrices such as blood or urine, hair has been increasingly investigated as a promising noninvasive alternative. However, understanding the pollutant distribution between differing biological compartments is essential for reliable interpretation of data collected.

Weaning is essential for foal growth and development. We determined the intestinal flora structure of donkey foals at the end of weaning (PreW_4d) and three stages after weaning (PostW_4d, PostW_8d, and PostW_15d) to explore the effects of weaning on intestinal development of donkey foals. The results showed that the main microbial flora in the gut of the donkey foal were Firmicutes and Bacteroides, and the proportion of Firmicutes gradually increased with weaning, which was an important reflection of the donkey foal's adaptability to the transition from lactose liquid feed to plant fiber solid feed.

Understanding the change in plant-associated microbial diversity and secondary metabolite biosynthesis in medicinal plants due to their cultivation in non-natural habitat (NNH) is important to maintain their therapeutic importance. Here, the bacterial endomicrobiome of Podophyllum hexandrum plants of natural habitat (NH; Kardang and Triloknath locations) and NNH (Palampur location) was identified and its association with the biosynthesis of podophyllotoxin (PTOX) was revealed. Rhizomes (source of PTOX) of plants of NH had highest endophytic bacterial diversity compared to NNH-plants.
