Polyethersulfone (PES) based membranes are used for dialysis, but exposure to blood can result in numerous interactions between the blood elements and the membrane. Adsorption and transformation of plasma proteins, activation of blood cells, adherence of platelets and thrombosis reactions against PES membrane can invoke severe blood reactions causing the increase rate of mortality and morbidity of hemodialysis (HD) patients. In order to minimize blood immune response, different biomimetic, zwitterionic, non-ionic, anticoagulant molecules and hydrophilic brushes were immobilized or blended with PES polymers. These additives modified the nature of the membrane, enhanced their biocompatibility and also increased the uremic waste dialysis properties. In this review, current perspectives of the different additives which are used with PES are highlighted in relation with PES membrane-associated blood reactions. The additive's purpose, compatibility, preparation techniques, methods of addition to polymer and influence on the chemistry and performance of hemodialysis membranes are described.

Purpose: Basophils play a crucial role in immunoglobulin E-mediated allergic reactions and parasitic infections. Recently, a low basophil count was reported to be a poor prognostic indicator in patients with malignant tumors. This study aimed to investigate the cut-off value to evaluate the clinicopathological and prognostic significance of the basophil count in patients with gastric cancer.

Background: Currently, there is a dearth of systematic research data on the phenomenon of false-positive reactions in treponemal tests. The aim of this study is to analyze the clinical characteristics and influencing factors associated with false-positive treponemal tests in patients, so as to enhance the diagnostic accuracy of syphilis and mitigate misdiagnosis-induced incorrect treatment.
Methods: From January 2017 to December 2023, a total of 759 cases with false-positive results for treponema were screened for blood transfusion, surgery, or other medical interventions at Jinling hospital.

Low-Level Tragus Stimulation [LL-TS] as a non-invasive technique of vagus nerve stimulation [VNS] moves to the fore in autonomic nervous system [ANS] studies as a non-drug based, easy applicable tool. LL-TS triggering a complex systemic response may offer a broader cardioprotective potential than expected as a recent investigation outlined blood pressure [BP] reduction by LL-TS in patients with hypertension which is commonly related to imbalance of the ANS as several other cardiovascular diseases.

The blood-brain-barrier prevents many imaging agents and therapeutics from being delivered to the brain that could fight central nervous system diseases such as Alzheimer's disease and strokes. However, techniques such as the use of stapled peptides or peptide shuttles may allow payloads through, with bioconjugation achieved bio-orthogonal tetrazine/norbornene click chemistry. A series of lanthanide-tetrazine probes have been synthesised herein which could be utilised in bio-orthogonal click chemistry with peptide-based delivery systems to deliver MRI agents through the blood-brain-barrier.
