Nutcracker Syndrome: A Rare Cause of Hematuria.

Nutcracker syndrome (NCS) is an uncommon vascular condition caused by the compression of the left renal vein (LRN), which may result in venous hypertension and clinical symptoms, including hematuria, flank pain, and pelvic congestion. This report describes the case of a 30-year-old woman with recurrent painless macroscopic hematuria, ultimately diagnosed with NCS based on clinical and radiological findings. Computed tomography (CT) angiography revealed a reduced aortomesenteric angle and LRN compression without signs of severe venous hypertension or collateral circulation.

[Neighborhood characteristics in Belo Horizonte, Minas Gerais State, Brazil: an intraurban analysis using systematic social observation method].

Systematic social observation (SSO) is an objective method of measuring the neighborhood physical and social characteristics. This study aimed to build intraurban indicators using the SSO method and compare them between two slums and their surroundings in a Brazilian capital. The simple indicators were calculated using the ratio estimator method, and grouped into domains.

Genetic characterization of paternal lineages by Y-STR in three sample populations in Northeastern Brazil.

Genetic markers of the Y chromosome are powerful tools for investigating paternal ancestry and are widely used in population and forensic genetics. However, in order to obtain statistics with a higher degree of certainty using these markers, it is necessary to obtain haplotypic frequencies from a representative database, as well as knowing the diversity and structure of the population. The aim of this study was to investigate the genetic diversity of a sample of 1114 unrelated men from three states in the Northeast of Brazil: Paraíba, Pernambuco and Ceará, through the analysis of 23 Y-STRs and to contribute to the expansion of the Brazilian database on these markers.

Toward Resolving Heterogeneous Mixtures of Nanocarriers in Drug Delivery Systems through Light Scattering and Machine Learning.

Nanocarriers (NCs) have emerged as a revolutionary approach in targeted drug delivery, promising to enhance drug efficacy and reduce toxicity through precise targeting and controlled release mechanisms. Despite their potential, the clinical adoption of NCs is hindered by challenges in their physicochemical characterization, essential for ensuring drug safety, efficacy, and quality control. Traditional characterization methods, such as dynamic light scattering and nanoparticle tracking analysis, offer limited insights, primarily focusing on particle size and concentration, while techniques like high-performance liquid chromatography and mass spectrometry are hampered by extensive sample preparation, high costs, and potential sample degradation.

Larvicidal and Oviposition Activity of Commercial Essential Oils of Ledeb., (Blanco) Benth., L. and Their Combinations Against .

is a vector responsible for the transmission of various arboviruses and is considered by the World Health Organization to be one of the main public health problems in the world. This study evaluated the larvicidal and oviposition activity of essential oils from , and and their formulations. Chromatographic analysis by GCMS identified a total of 28, 52 and 18 compounds for the oils of the species , and , respectively.
