Label-Free Mapping of Multivalent Binding Pathways with Ligand-Receptor-Anchored Nanopores.

Understanding single-molecule multivalent ligand-receptor interactions is crucial for comprehending molecular recognition at biological interfaces. However, label-free identifications of these transient interactions during multistep binding processes remains challenging. Herein, we introduce a ligand-receptor-anchored nanopore that allows the protein to maintain structural flexibility and favorable orientations in native states, mapping dynamic multivalent interactions.

Replacing soybean meal with fermented rapeseed meal in diets: potential effects on growth performance, antioxidant capacity, and liver and intestinal health of juvenile tilapia (Oreochromis niloticus).

This study aims to evaluate the effects of substituting soybean meal with fermented rapeseed meal (FRM) on growth, antioxidant capacity, and liver and intestinal health of the genetically improved farmed tilapia (GIFT, Oreochromis niloticus). A total of 450 tilapia (7.22 ± 0.

The efficacy of Fuke Qianjin tablets combined with clomiphene citrate on infertility patients with polycystic ovary syndrome: A retrospective analysis.

Purpose: Clinical efficacy of Fuke Qianjin tablets combined with clomiphene citrate on infertility patients with polycystic ovary syndrome (PCOS) was expected to be retrospectively analyzed in this study.

Methods: In this paper, 100 infertility patients with PCOS were selected and divided into the observation and control groups based on different medications. Firstly, clinical data of both groups of patients were acquired.

[Chicken-claw needling at Xiaguan (ST 7) combined with intradermal needling on negative emotions in primary trigeminal neuralgia of phlegm obstruction and blood stasis: a randomized controlled trial].

Objective: To observe the clinical effect of chicken-claw needling at Xiaguan (ST 7) combined with intradermal needling on negative emotion in primary trigeminal neuralgia (PTN) of phlegm obstruction and blood stasis.

Methods: Sixty cases of patients with PTN of phlegm obstruction and blood stasis were randomly divided into an observation group and a control group, 30 cases in each group. The observation group was treated with chicken-claw needling at Xiaguan (ST 7) combined with intradermal needling (acupoints Sibai [ST 2], Yuyao [EX-HN 4], Hegu [LI 4], Taichong [LR 3] and auricular points Xin [CO], Shenmen [TF], Pizhixia [AT], etc.

Proteomic Analysis Dissects Molecular Mechanisms Underlying Plant Responses to Phosphorus Deficiency.

Phosphorus (P) is an essential nutrient for plant growth. In recent decades, the application of phosphate (Pi) fertilizers has contributed to significant increases in crop yields all over the world. However, low efficiency of P utilization in crops leads to intensive application of Pi fertilizers, which consequently stimulates environmental pollution and exhaustion of P mineral resources.

[Clinical observation on deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle for trigeminal neuralgia of wind and heat].

Objective: To compare the clinical therapeutic effect between deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle and conventional acupuncture in patients with trigeminal neuralgia (TN) of wind and heat, and explore its mechanism.

Methods: A total of 60 patients with TN of wind and heat were randomized into an observation group (30 cases) and a control group (30 cases). In the observation group, deep needling with round sharp needle was applied at Xiaguan (ST 7), and tapping with plum-blossom needle was applied at Yangbai (GB 14), Quanliao (SI 18), Dicang (ST 4), Sibai (ST 2), etc.
