Albumin is a versatile protein used as a carrier system for cancer therapeutics. As a carrier it can provide tumor specificity, reduce drug related toxicity, maintain therapeutic concentration of the active moiety like drug, gene, peptide, protein etc. for long period of time and also reduce drug related toxicities. Apart from cancer therapy, it is also utilized in the imaging and multimodal therapy of cancer. This review highlights the important properties, structure and types of albumin based nanocarriers with regards to their use for cancer targeting. It also provides brief discussion on methods of preparation of these nanocarriers and their surface modification. Applications of albumin nanocarriers for cancer therapy, gene delivery, imaging, phototherapy and multimodal therapy have also been discussed. This review also provides brief discussion about albumin based marketed nano formulations and those under clinical trials.

Albumin and γ-globulin concentrations in subcutaneous adipose tissues (SAT) have been quantified by multivariate regression based on admittance relaxation time distribution (mraRTD) under the fluctuated background of sodium electrolyte concentration. The mraRTD formulates P = Ac + Ξ (P: peak matrix of distribution function magnitude ɣP and frequency τP, c: concentration matrix of albumin cAlb, γ-globulin Gloc, and sodium electrolyte Nac, A: coefficient matrix of a multivariate regression model, and Ξ: error matrix). The mraRTD is implemented by two processes which are: 1) the training process of A through the maximum likelihood estimation of P and 2) the quantification process of cAlb, Gloc, and Nac through the model prediction.

Purpose: The albumin to fibrinogen ratio (AFR), a biomarker associated with inflammatory, nutritional, and coagulation status, and the CALLY index, a biomarker combining C-reactive protein, albumin, and lymphocyte count, have been suggested to correlate with prognosis in a variety of diseases in previous studies; however, studies of these two markers in ulcerative colitis (UC) are lacking. The aim of this study was to evaluate the clinical significance of AFR and CALLY index in UC.
Methods: The study included 109 UC patients and 126 healthy controls.

The extracellular vesicle release in red blood cell concentrates reflects progressive accumulation of storage lesions and could represent a new measure to be implemented routinely in blood centres in addition to haemolysis. Nevertheless, there is currently no standardized isolation protocol. In a previous publication, we developed a reproducible ultracentrifugation-based protocol (20,000 × protocol) that allows to classify red blood cell concentrates into three cohorts according to their vesiculation level.

Background: Patients diagnosed with non-small cell lung cancer (NSCLC) usually have a poor prognosis, so it is critical to identify effective biomarkers for prognosis prediction. The aim of this study is to establish a nomogram to evaluate the prognostic significance of blood markers in patients with NSCLC and provide reference for clinical work.
Methods: A total of 486 patients with NSCLC who were admitted to hospital from January 2009 to December 2019 were retrospectively analyzed.

Purpose: Inflammatory, nutritional, and immune biomarkers are associated with the prognosis of patients with various tumors. Recently, a comprehensive predictive biomarker, the hemoglobin, albumin, lymphocyte, and platelet (HALP) score, was introduced to predict clinical outcomes. We investigated the prognostic impact of preoperative HALP scores in patients who underwent hepatectomy for colorectal liver metastasis (CRLM).
