This study presents an innovative approach for authenticating the geographical origin of instant coffee from Southern Bahia using vibrational spectral data coupled with Data-Driven Soft Independent Modeling of Class Analogy (DD-SIMCA). Combining data from a benchtop mid-infrared (MIR) spectrometer and a portable near-infrared (NIR) spectrometer, the methodology achieved 100 % efficiency with Multiplicative Scatter Correction (MSC) and Standard Normal Variate (SNV) pre-processing, alongside offset correction for MIR data. MIR spectroscopy enabled detailed chemical composition analysis, while the portable NIR spectrometer provided cost-effective in situ capabilities.

Macrocyclic peptides are a promising chemotype for drug discovery, given their attractive properties of proteolytic stability, bioavailability and the ability to inhibit protein-protein interactions. Approaches to the generation of macrocyclic peptides include optimisation of hits from library screening; de novo design from known ligands and antibody paratopes or protein-protein interactions; constraint of linear peptides to afford beneficial properties of macrocycles; and novel approaches to cyclisation. We describe the recent literature and exemplify these approaches in the design of peptide macrocycles, and the benefits of incorporating computational and structure-guided approaches into compound design and optimisation.

The abiu-do-mato (Pouteria caimito) is a fruit highly valued by Amazonian populations; however, its chemical composition and properties remain largely unexplored. This study aimed to fill this gap by analyzing the fruit's chemical profile and evaluating its antioxidant and cytotoxic properties. The research assessed proximate composition through physicochemical analysis, mineral content via atomic absorption spectrophotometry, and antioxidant activity using DPPH, ABTS, and FRAP assays.

Setting: To appropriately triage and evaluate people with signs or symptoms of pulmonary TB, clinical, laboratory, and radiological variables, as well as biomarkers, have been prioritised to increase early detection. However, in high TB prevalence areas, few studies used standardised tools to assess both sociodemographic characteristics and accessible biomarkers comprehensively. This study aimed to describe the sociodemographic, radiographic, clinical, and laboratory characteristics associated with pulmonary TB (PTB) in patients with presumed pulmonary TB (pPTB).

Knowing how to define, understand the pathophysiology, diagnose, monitor and treat with lifestyle changes, and adjust antihypertensive drugs to achieve the recommended blood pressure (BP) target - to reduce morbidity and mortality - requires specific knowl-edge and approaches within the contexts of hemodialysis (HD) and peritoneal dialysis (PD). This document is the first guideline of the Brazilian Society of Nephrology, developed by the departments of Hypertension and Dialysis.
