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.

Microalgae are often used in different industrial sectors and can be used as indicators of aquatic environmental health. An essential step for cultivating microalgae is assessing the cell density, which is traditionally performed through cell counting by optical microscopy (OM). However, this method has limitations, mainly in terms of runtime and low reproducibility.

Background: Several clinical trials showed that sodium-glucose cotransporter 2 (SGLT2) inhibitors have protective effects against chronic kidney disease (CKD) in both patients with and those without type 2 diabetes mellitus. Since one of the renoprotective mechanisms of SGLT2 inhibitors is thought to be amelioration of glomerular hyperfiltration, we hypothesized that an enlarged glomerular diameter, which suggests increased single-nephron glomerular filtration rate, is associated with a reduction in urinary protein after treatment with an SGLT2 inhibitor.
Methods: This study was a retrospective multicentered study including 28 adult patients with CKD who underwent kidney biopsy and were then treated with dapagliflozin, an SGLT2 inhibitor.
Exploring the safety and feasibility of intracameral Aprokam® (cefuroxime sodium) in pediatric cataract surgery.
Int Ophthalmol
January 2025
Cleveland Clinic Abu Dhabi, Eye Institute, Abu Dhabi, United Arab Emirates.
Purpose: To describe the safety and assess the feasibility of using intracameral cefuroxime sodium (Aprokam®) during congenital cataract surgery as a preventive measure for endophthalmitis.
Design: Monocentric, prospective, observational pilot study.
Setting: San Giuseppe Hospital, University of Milan, Milan, Italy.
Sustainable synthesis of 1,2,3-triazoles using Cyrene as a biodegradable solvent in click chemistry.

Universita degli Studi di Milano, Department of Chemistry, Via Golgi 19, 20133, Milan, ITALY.
The first successful synthesis of 1,2,3-triazoles using CyreneTM as a biodegradable and non-toxic solvent in click chemistry has been developed. In contrast to previous methods, this sustainable approach allows product isolation by simple precipitation in water, eliminating the need for organic solvent extractions and column chromatography purifications, thus minimizing waste consumption while reducing operational costs. The protocol, performed also at gram scale, has broad applicability and versatility, as shown with complex substrates like biologically active coumarins or triazole-linked bifunctional molecules.
