Characterization and functional analysis of a novel C-type lectin in blunt snout bream (Megalobrama amblycephala).

C-type lectins, one of the pattern recognition receptors (PRRs), play significant roles in innate immune responses through binding to the pathogen-associated molecular patterns (PAMPs) presented on surfaces of microorganisms. Here, a novel C-type lectin (named as MaCTL) from blunt snout bream (Megalobrama amblycephala) was cloned and characterized. The open reading frame (ORF) of MaCTL is 573 bp long encoding a putative protein of 190 amino acids (aa), which contains a typical feature of signal peptide at 1-23 aa, a characteristic CRD domain at 45-178 aa and a WND/EPN motif that is required for carbohydrates-binding specificity.

[Health Risk Assessment of Heavy Metals in Soil and Wheat Grain in the Typical Sewage Irrigated Area of Shandong Province].

Sewage irrigation is a common alternative to make up for the shortage of agricultural irrigation in intensive agricultural areas. Abundant organic matter and nutrients in sewage can improve soil fertility and crop yield, but hazardous materials, such as heavy metals, will damage the soil environmental quality and threaten human health. To better understand the characteristics of heavy metal enrichment and potential health risk in a sewage irrigated soil-wheat system, a total of sixty-three pairs of topsoil and wheat grain samples were collected from the sewage irrigated area of Longkou City in Shandong Province.

Periodontitis & preeclampsia: were outer membrane vesicles a potential connection?

Preeclampsia (PE) is gestation-specific hypertension coupled by systemic multiple organ damages, remaining the leading causes of maternal and infant death worldwide. Though numerous pathogenetic mechanisms have been engaged in this disorder and several methods have been undertaken to treat PE, few clinical strategies are effective in PE management, suggesting more studies from novel perspective being in great need to decipher the underlying mechanisms of PE. Growing evidence shows that women with periodontitis, an oral microflora-induced chronic inflammation of the periodontal tissues, are more inclined to suffer PE, which may be tightly associated with microflora-derived outer membrane vesicles (OMVs).

Association between Days Open and Parity, Calving Season or Milk Spectral Data.

Meanwhile, the parity and calving season of dairy cows were also studied to characterize the difference in DO between groups of these two cow-level factors. The result of the linear mixed-effects model revealed that no significant differences were observed between the parity groups.

Structural basis for the arsenite binding and translocation of Acr3 antiporter with NhaA folding pattern.

The arsenical resistance-3 (ACR3) family constitutes the most common pathway that confers high-level resistance to toxic metalloids in various microorganisms and lower plants. Based on the structural model constructed by AlphaFold2, the Acr3 antiporter from Bacillus subtilis (Acr3 ) exhibits a typical NhaA structure fold, with two discontinuous helices of transmembrane (TM) segments, TM4 and TM9, interacting with each other and forming an X-shaped structure. As the structural information available for these important arsenite-efflux pumps is limited, we investigated the evolutionary conservation among 300 homolog sequences and identified three conserved motifs in both the discontinuous helices and TM5.
