Urolithins
The impact of host–microbiome interactions on cognitive health and disease has received increasing attention. Microbial-derived metabolites produced in the gut are one of crucial mechanisms of the gut–brain axis interaction, showing attractive perspectives. Urolithins (Uros) are gut microbial-derived metabolites of ellagitannins and ellagic acid, whose biotransformation varies considerably between individuals and decreases greatly with age.

Urogenital Schistosomiasis
Schistosomiasis is the most important helminthiasis worldwide in terms of morbidity and mortality. Most of the infections occurs in Africa, which about two thirds are caused by Schistosoma haematobium. The infection with S. haematobium is considered carcinogenic leading to squamous cell carcinoma (SCC) and urothelial carcinoma of the urinary bladder.

Urocortin and Myocardila Infarction
Ucn is a mammalian peptide member of the corticotropin-releasing factor (CRF) family. Three isoforms of Ucn have been described so far, Ucn1, Ucn2, and Ucn3, which differ in terms of their structure, expression, and affinity to CRF receptors.

URL Normalization
URL normalization is the process by which URLs are modified and standardized in a consistent manner. The goal of the normalization process is to transform a URL into a normalized URL so it is possible to determine if two syntactically different URLs may be equivalent. Search engines employ URL normalization in order to assign importance to web pages[clarify] and to reduce indexing of duplicate pages. Web crawlers perform URL normalization in order to avoid crawling the same resource more than once. Web browsers may perform normalization to determine if a link has been visited or to determine if a page has been cached.

Urine Peptidome
Urine is perhaps, of all biofluids, the one with greater potential in clinical peptidomics. Urinary proteins and peptides originate from the secretions of renal tubular epithelial cells, shedding of cells along the urinary tract, exosome secretion, and more importantly, from glomerular filtration of plasma. Therefore, beyond the renal system’s pathophysiological status, the urinary peptidome is influenced by systemic disturbances.

Urine HPV Testing
Urine HPV detection has the potential to become a most promising tool that could expand the possibilities in changing genital and cervical cancer prevention strategies as well as in the surveillance and management of genital precancer.

Urine Biomarkers of Lupus Nephritis
The kidney is one of the main organs affected by the autoimmune disease systemic lupus erythematosus (SLE). Lupus nephritis (LN) concerns 30–60% of adult SLE patients and it is significantly associated with an increase in the morbidity and mortality. The definitive diagnosis of LN can only be achieved by histological analysis of renal biopsies, but the invasiveness of this technique is an obstacle for early diagnosis of renal involvement and a proper follow-up of LN patients under treatment. The use of urine for the discovery of non-invasive biomarkers for renal disease in SLE patients is an attractive alternative to repeated renal biopsies, as several studies have described surrogate urinary cells or analytes reflecting the inflammatory state of the kidney, and/or the severity of the disease.

Urinary Tract Infections during the COVID-19 Pandemic
The landscape of management of urinary tract infections (UTI) is changing rapidly. The COVID-19 pandemic draws the attention to the SARS-CoV-2 management with a subsequent reduced attention on bacterial infections. The COVID-19 diffusion containing procedures, such as use of facemasks and handwashing, have reduced spreading of bacteria and bacterial lung infections.

Urinary Tract Infections and Microbiota
Urinary tract infections (UTIs) belong among the most common bacterial infections. They comprise the contamination of the periurethral space by specific uropathogens residing in the gut, followed by urethral colonization and pathogen ascension to the urinary bladder. Studying the association between gut microbiota and subsequent development of bacteriuria and UTI is of great interest and importance. Nevertheless, with discovering a multifaceted, symbiotic microbiome in the healthy urogenital tract, the well-established diagnostic and therapeutic approaches for the urinary tract infections (UTIs) need to be re-assessed. Precisely, emerging data suggest that vaginal dysbiosis may result in Escherichia coli colonization and prompt recurrent UTIs. At the same time, urinary microbiome perturbations may precede UTIs' development and other pathologic conditions of the urinary system. Therefore, by the thoroughly assessment of specific gut, urinary tract, and genital tract microbiomes regarding their potential influence on UTI development, knowledge for the incidence reduction and new treatment approaches will be obtained.
