Prostatic artery embolization (PAE) has emerged as a truly minimally invasive treatment option for patients with lower urinary tract symptoms presumed secondary to benign prostatic obstruction (LUTS/BPO) over the last few years and is now supported by evidence-based international guidelines. Here, we provide an overview on the profile of PAE based on the most relevant and recent literature.

A comprehensive review of literature on PAE was conducted on PubMed-Medline. The most relevant literature was summarized narratively.

While there is still a lack of long-term data, efficacy and safety data have been published for the short to mid-term. As with any minimally invasive technique, relief of bladder outlet obstruction is less pronounced after PAE compared to more invasive resective techniques. This is likely to be associated with higher re-intervention rates during the longer term. However, due to its beneficial safety profile, PAE represents an interesting option for many patients and could fill a niche between pharmacotherapy and formal surgical intervention. Given its unique treatment approach, i.e. endovascular instead of transurethral, PAE has a clearly different profile compared to other minimally invasive treatments. Performance with local anesthesia with possible continuation of anticoagulant drugs and no upper prostate size limit are the most important advantages of PAE.

PAE represents a valuable supplement in the treatment armamentarium of LUTS/BPH if patients are selected appropriately.

Moreover, their role as stationary phase in chromatography is gaining relevance. We investigate a material consisting of multiwall carbon nanotubes (CNTs) and superparamagnetic iron oxide nanoparticles towards its use as a mixed-mode chromatography material. The idea is to immobilize the ion exchange material iron oxide on CNTs as a stable matrix for chromatography processes without a significant pressure drop. Iron oxide nanoparticles are synthesized and used to decorate the CNTs via a co-precipitation route. They bind to the walls of oxidized CNTs, thereby enabling to magnetically separate the composite material. This hybrid material is investigated with transmission electron microscopy, magnetometry, X-ray diffraction, X-ray photoelectron and Raman spectroscopy. Moreover, we determine its specific surface area and its wetting behavior. Cerdulatinib We also demonstrate its applicability as chromatography material for amino acid retention, describing the adsorption and desorption of different amino acids in a complex porous system surrounded by aqueous media. Thus, this material can be used as chromatographic matrix and as a magnetic batch adsorbent material due to the iron oxide nanoparticles. Our work contributes to current research on composite materials. Such materials are necessary for developing novel industrial applications or improving the performance of established processes.

We aim to review the most relevant diagnostic features and treatment options of retroperitoneal fibrosis, in order to provide a useful guide for clinical practice.

The recent literature highlights the role of imaging studies such as computed tomography, magnetic resonance imaging and positron emission tomography as useful tools for the diagnosis of retroperitoneal fibrosis, with retroperitoneal biopsy being reserved to atypical cases. The treatment approach is mainly conservative and is based on the use of medical therapies plus urological interventions. Medical therapies essentially comprise glucocorticoids and immunosuppressants-either traditional or biological agents such as rituximab. Surgical ureterolysis is only left for refractory cases. Recent findings in retroperitoneal fibrosis highlight the possibility of a non-invasive diagnostic approach and a conservative treatment strategy.

Theoretical and modelling approaches were undertaken on Nigerian livestock industry to estimate financial losses due to African animal trypanosomosis.

Surveys were conducted between March 2018 and February 2019 to include focus group interactions, in-depth household engagements concerning livestock practices in relation to AAT. Financial losses estimation on livestock were targeted to provide ways to regain cost and maximize household livelihoods. Mathematical equation was developed to project the effects of intervention strategies. Important variables such as mean AAT prevalence, incidence rate, birth rate, morbidity and mortality were estimated and inserted in the model.

Mean total income per capita was US$ 1.31 / person / day among livestock producers in Nigeria. A total of US$ 518. 9 million were estimated from direct losses, while US$ 58.8 million as indirect losses. Annual estimated losses to AAT from cattle, sheep, goat and pigs in Nigeria is US$ 577.7 million. This is equivalent to 207.98 billion Nigerian naira and represents 6.93% of annual livestock GDP in the country. This could increase to 85% in the next 50 years if there are no proper control interventions. Control efforts could reduce the losses to US$ 16.7 million at the rate of 0.2% during the same period.

AAT has severe socioeconomic impact on producer's livelihood and urgent improved control intervention strategies should be instituted to reduce the losses attributed to the disease.

Microbiome, the community of microorganisms that has co-evolved with human hosts, plays a pivotal role in human health and disease. This invisible "essential organ" supplies the host with a myriad of chemicals and molecules. In turn, microbial metabolites can serve as messengers for microbes to communicate with each other and in the cross-talk with host cells. Gut dysbiosis in SpA is associated with altered microbial metabolites, and an accumulated body of research has contributed to the understanding that changes in intestinal microbiota can modulate disease pathogenesis. We review the novel findings from human and animal studies to provide an overview of the contribution of individual microbial metabolites and antigens to SpA.Spondyloarthritis (SpA) is a heterogeneous group of chronic inflammatory diseases of unknown etiology. Over time, the plethora of cellular elements involved in its pathogenesis has progressively enriched together with the definition of specific cytokine pathways. Recent evidence suggests the involvement of new cellular mediators of inflammation in the pathogenesis of SpA or new subgroups of known cellular mediators. The research in this sense is ongoing, and it is clear that this challenge aimed at identifying new cellular actors involved in the perpetuation of the inflammatory process in AxSpA is not a mere academic exercise but rather aims to define a clear cellular hierarchy. Such a definition could pave the way for new targeted therapies, which could interfere with the inflammatory process and specific pathways that trigger immune system dysregulation and stromal cell activity, ultimately leading to significant control of the inflammation and new bone formation in a significant number of patients. In this review, we will describe the recent advances in terms of new cellular actors involved in the pathogenesis of SpA, focusing our attention on stromal cells and innate and adaptive immunity cells.

Large vessel vasculitides (LVVs) are inflammatory conditions of the wall of large-sized arteries, mainly represented by giant cell arteritis (GCA) and Takayasu arteritis (TA). The inflammatory process within the vessel wall can lead to serious consequences such as development of aneurysms, strokes and blindness; therefore, early diagnosis and follow-up of LVV are fundamental. However, the arterial wall is poorly accessible and blood biomarkers are intended to help physicians not only in disease diagnosis but also in monitoring and defining the prognosis of these conditions, thus assisting therapeutic decisions and favouring personalised management. The field is the object of intense research as the identification of reliable biomarkers is likely to shed light on the mechanisms of disease progression and arterial remodelling. In this review, we will discuss the role of blood biomarkers in LVVs in the light of the latest evidence.

In clinical practice, the most widely performed laboratory investigations aresing biomarkers so far identified are NT-proBNP, which reflects myocardial strain; pentraxin-3, which has been associated with recent optic nerve ischemia; and endothelin-1, which is associated with ischaemic complications. Currently, the use of these molecules in clinical practice is limited because of their restricted availability, lack of sufficient studies supporting their validity and associated costs. Further evidence is required to better interpret their biological and clinical value.

Failure of pancreatic and duodenal homeobox factor 1 (PDX1) to localise in the nucleus of islet beta cells under high-fat diet (HFD) conditions may be an early functional defect that contributes to beta cell failure in type 2 diabetes; however, the mechanism of PDX1 intracellular mislocalisation is unclear. Stress granules (SGs) are membrane-less cytoplasmic structures formed under stress that impair nucleocytoplasmic transport by sequestering nucleocytoplasmic transport factors and components of the nuclear pore complex. In this study, we investigated the stimulators that trigger SG formation in islet beta cells and the effects of SGs on PDX1 localisation and beta cell function.

The effect of palmitic acid (PA) on nucleocytoplasmic transport was investigated by using two reporters, S-tdTomato and S-GFP. SG assembly in rat insulinoma cell line INS1 cells, human islets under PA stress, and the pancreas of diet-induced obese mice was analysed using immunofluorescence and immunoblotting. SG protein componentngs suggest a link between SG formation and beta cell dysfunction in the presence of SFAs. Preventing SG formation may be a potential therapeutic strategy for treating obesity and type 2 diabetes.
