Concentration of facultative pathogenic bacteria and antibiotic resistance genes during sewage treatment and in receiving rivers
Whereas the hygienic condition of drinking and bathing water by law must be monitored by culture-based methods, for quantification of microbes and antibiotic resistance in soil or the aquatic environment, often molecular genetic assays are used. For comparison of both methods, knowledge of their correlation is necessary. Therefore the population of total bacteria, Escherichia coli, ...

Raman imaging at biological interfaces: applications in breast cancer diagnosis
Abstract Background: One of the most important areas of Raman medical diagnostics is identification and characterization of cancerous and noncancerous tissues. The methods based on Raman scattering has shown significant potential for probing human breast tissue to provide valuable information for early diagnosis of breast cancer. A vibrational fingerprint from the biological tissue provides ...

Diagnostic yield of automatic and patient-triggered ambulatory cardiac event recording in the evaluation of patients with palpitations, dizziness, or syncope.
BACKGROUND: Recent studies have shown that patient-triggered cardiac event recorders (CER) have an increased diagnostic yield and are more cost effective than conventional 24-h-Holter electrocardiograms (ECGs) for the evaluation of sporadic, potentially arrhythmia-related symptoms. HYPOTHESIS: The aim of this study was to determine the diagnostic yield of a patient-triggered CER combined with ...

3D Bioprinting Of Prevascularised Implants For The Repair Of Critically-Sized Bone Defects
By combining different cell populations in a fibrin bioink, researchers from Trinity College Dublin, Royal College of Surgeons in Ireland and University of Illinois Chicago were able to sprout an in vitro microvessel network that was then exploited to prevascularise a 3D printed scaffold implanted in a critical size femoral defect using REGENHU bioprinter. This dual approach was observed to ...

A Novel, High-Throughput Platform to Characterize Novel IBD Therapeutics
Tumor Necrosis Factor Alpha (TNF-a) is a potent cytokine that is over-expressed by cells during chronic intestinal inflammation. Furthermore, TNF-a represents the most validated clinical target for ulcerative colitis (UC) and inflammatory bowel diseases (IBD) with multiple emerging neutralizing/inflammation-reducing therapeutics targeting this cytokine for inactivation. TNF-a activation of ...

UCT Silane Cited in Clinical Microbiology
Fungal bloodstream infections have been noted as a significant problem in many countries including the United States, with an attributable mortality rate of up to 40%. An early diagnosis to direct appropriate therapy has been shown to be critical to reduce mortality rates. Conventional phenotypic methods for fungal detection take several days, which is often too late to impact outcomes. The ...

RNA Sequencing Increases the Chance of RNA Biomarker Discovery
Biomarkers are defined as measurable biological characteristics that are associated with normal or pathological conditions. They possess clinical relevance, including diagnostic, prognostic, and predictive values. RNA, not only an essential part of the central dogma, is certainly a relatively untapped resource for biomarker discovery of various diseases. Cumulating data shows that RNA ...

Amplicon Sequencing for Microbiome Research: Introduction, Advantages, and Applications
The identification of microbial groups is an important step in understanding the interrelationship of microorganisms in a community. It is done to determine all present microbial taxa and their relative abundance, and as well their phylogenetic relationships. One of the methods used to establish phylogenetic relationships is by sequencing common genes. One of the easiest genes to be sequenced are ...

How Much Do You Know about Bacteriocin?
In recent years, the increase in the number of multi-drug resistant pathogens and food safety have become serious global problems, and it is increasingly important to find or develop a new generation of antibacterial drugs or preservatives. Scientists have discovered that bacteria-produced bacteriocins can control clinically relevant susceptible and resistant bacteria, and purified bacteriocins ...

Introduction to Shotgun Metagenomics, From Sampling to Data Analysis
Metagenomics is the science that applies high-throughput sequencing technologies and bioinformatics tools to directly obtain the genetic content of a microbial community without the need to isolate and culture the individual microbial species. Metagenomics enables researchers not only to study the functional gene composition of microbial communities but also to conduct evolutionary research. ...

Driving Data-driven Medicine to Advance Personalized Care
Clinical trials are often designed with the participant’s everyday life in mind – trying to gather as much clinically-relevant data in a controlled manner as possible while allowing individuals to live their regular lives. However, it is true that trials are artificial environments, and participants are actively monitored to ensure their safety and to determine the efficacy of a drug ...

Borrelia burgdorferi sensu stricto is clonal in patients with early lyme borreliosis
Lyme borreliosis, the most commonly reported vector-borne disease in North America, is caused by the spirochete Borrelia burgdorferi. Given the extensive genetic polymorphism of B. burgdorferi, elucidation of the population genetic structure of the bacterium in clinical samples may be relevant for understanding disease pathogenesis and may have applicability for the development of diagnostic ...

Development of a Bioartificial Vascular Pancreas
Abstract Transplantation of pancreatic islets has been shown to be effective, in some patients, for the long-term treatment of type 1 diabetes. However, transplantation of islets into either the portal vein or the subcutaneous space can be limited by insufficient oxygen transfer, leading to islet loss. Furthermore, oxygen diffusion limitations can be magnified when islet numbers are increased ...

Proteins That Provide Key Information to Identify Patients with Poor Prognosis Found
In recent years, immune-based cancer treatment methods have given doctors and patients a lot of hope. Drugs called immune checkpoint inhibitors have provided life-saving benefits to more and more people suffering from melanoma, lung cancer, bladder cancer, and many other types of cancer. Although these drugs are exciting, a frustrating sticking point is that doctors cannot predict who will ...

CBD: Perils, Promise and Development for Neuropathic Pain
Cannabidiol, or CBD, is one of several compounds extracted from the cannabis (marijuana) plant. In recent years, CBD has become enormously popular, and its market is believed to be hundreds of millions of dollars. Believers and users of CBD extoll its benefits for inflammation, muscle soreness, pain, anxiety and a whole host of other things, including cancer. It is, however, very understudied. ...

What causes heart failure with preserved ejection fraction (HFpEF)?
Heart failure with preserved ejection fraction (HFpEF) is a multifactorial and multisystemic disorder that represents more than 50% of all heart failure cases.[1] Epidemiologic data from the Framingham Study, an international cohort study, shows a rapid increase in the prevalence of HFpEF over the past three decades, from 41% to 56% and, conversely, a decrease in the prevalence of HFrEF from 44% ...

LC/MS/MS analysis of metabolites of synthetic Cannabinoids JWH-018 and JWH-073 in Urine
Abstract A liquid chromatographic method was developed to resolve a comprehensive set of metabolites of JWH-018 and JWH-073. In addition to the chromatographic analysis method, an extraction method was developed to recover a broad range of synthetic cannabinoid metabolites, including carboxylic acid metabolites that are not traditionally recovered using a high pH liquid/liquid extraction. The ...
