Mechanisms Underlying Iron Deficiency-Induced Cardiac Disorders: Implications for Treatment.

Two billion people worldwide suffer from anemia, which can lead to the onset of cardiac disorders; nevertheless, the precise mechanisms remain unclear. There are at least three distinct mechanisms by which iron deficiency (ID) contributes to the development of cardiac disorders. First, ID increases concentrations of intact fibroblast growth factor-23 (iFGF-23), which promotes left ventricular hypertrophy.

Oxytetracycline hyper-production through targeted genome reduction of .

Most biosynthetic gene clusters (BGC) encoding the synthesis of important microbial secondary metabolites, such as antibiotics, are either silent or poorly expressed; therefore, to ensure a strong pipeline of novel antibiotics, there is a need to develop rapid and efficient strain development approaches. This study uses comparative genome analysis to instruct rational strain improvement, using , the producer of the important antibiotic oxytetracycline (OTC) as a model system. Sequencing of the genomes of two industrial strains M4018 and R6-500, developed independently from a common ancestor, identified large DNA rearrangements located at the chromosome end.

Frontal theta oscillations during emotion regulation in people with borderline personality disorder.

Background: Borderline personality disorder (BPD) is a severe psychiatric disorder conceptualised as a disorder of emotion regulation. Emotion regulation has been linked to a frontolimbic network comprising the dorsolateral prefrontal cortex and the amygdala, which apparently synchronises its activity via oscillatory coupling in the theta frequency range.

Aims: To analyse whether there are distinct differences in theta oscillatory coupling in frontal brain regions between individuals with BPD and matched controls during emotion regulation by cognitive reappraisal.

Prebiotics have been sidelined in sports nutrition and their effect on performance remains poorly investigated and understood.

Experimental Approach: Eighteen healthy male basketball players were divided into two groups; one received 17 g/day of soluble dietary fibre (Nutriose®) for four weeks and the other group received placebo.

Molecular Aspects of MAFLD-New Insights on Pathogenesis and Treatment.

Metabolic-associated liver disease (MAFLD) affects up to 70% of overweight and more than 90% of morbidly obese people, and its pathogenesis is rather complex and multifactorial. The criteria for MAFLD include the presence of hepatic steatosis in addition to one of the following three criteria: overweight or obesity, presence of type 2 diabetes mellitus (T2DM), or evidence of metabolic dysregulation. If the specific criteria are present, the diagnosis of MAFLD can be made regardless of alcohol consumption and previous liver disease.

Assessment of morphometric and volumetric changes in lacrimal glands in thyroid eye disease, its clinical manifestations in relation of disease progression. Retrospective volumetric analysis included both genders and was performed on total of 183 patients - 91 patients with diagnosed Grave's disease and thyroid eye disease and 92 patients without Grave's disease and thyroid eye disease who underwent multidetector computed tomography (MDCT) examination in routine daily work according to other medical indications. In the group of females, there was statistical significance between patients with thyroid eye disease and controls who were smoking and had body weight gain.

Current Viewpoint on Female Urogenital Microbiome-The Cause or the Consequence?

An increasing amount of evidence implies that native microbiota is a constituent part of a healthy urinary tract (UT), making it an ecosystem on its own. What is still not clear is whether the origin of the urinary microbial community is the indirect consequence of the more abundant gut microbiota or a more distinct separation exists between these two systems. Another area of uncertainty is the existence of a link between the shifts in UT microbial composition and both the onset and persistence of cystitis symptoms.

Differences in tolerogenic status of NK cells between luminal A type, luminal B type, and triple-negative breast cancer.

Globally, breast cancer is the main cause of death among female cancer patients. The tumor-infiltrating lymphocytes (TILs) in breast cancer are associated with a more favorable outcome of a disease. Natural killer (NK) cells are important cytotoxic cells involved in tumor immunosurveillance, causing the direct killing of tumor cells.

Recent studies have shown that AI has been successfully applied in the healthcare sector. The objective of this paper is to perform a systematic review to summarize the electroencephalogram (EEG) findings in patients with coronavirus disease (COVID-19) and databases and tools used in artificial intelligence algorithms, supporting the diagnosis and correlation between lung disease and brain damage, and lung damage.

Reference-Grade Genome and Large Linear Plasmid of Streptomyces rimosus: Pushing the Limits of Nanopore Sequencing.

Streptomyces rimosus ATCC 10970 is the parental strain of industrial strains used for the commercial production of the important antibiotic oxytetracycline. As an actinobacterium with a large linear chromosome containing numerous long repeat regions, high GC content, and a single giant linear plasmid (GLP), these genomes are challenging to assemble. Here, we apply a hybrid sequencing approach relying on the combination of short- and long-read next-generation sequencing platforms and whole-genome restriction analysis by using pulsed-field gel electrophoresis (PFGE) to produce a high-quality reference genome for this biotechnologically important bacterium.

Significance of Biomarkers in Early Diagnosis of Abdominal Sepsis.

Introduction/objective: Peritonitis is one of the most important sources of abdominal sepsis. Since intra-abdominal infection leads to the activation of the inflammatory response, this suggested that some of these mediators could be used as markers of the severity of newly formed sepsis, but primarily to identify or rule out new-onset sepsis. The aim of this study was to evaluate the sensitivity and specificity of serum markers of inflammation: C-reactive protein, procalcitonin and serum amyloid A in the serum of patients with diffuse secondary peritonitis.

The New Therapeutic Approaches in the Treatment of Non-Alcoholic Fatty Liver Disease.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease which is characterized by extremely complex pathogenetic mechanisms and multifactorial etiology. Some of the many pathophysiological mechanisms involved in the development of NAFLD include oxidative stress, impaired mitochondrial metabolism, inflammation, gut microbiota, and interaction between the brain-liver-axis and the regulation of hepatic lipid metabolism. The new therapeutic approaches in the treatment of NAFLD are targeting some of these milestones along the pathophysiological pathway and include drugs like agonists of peroxisome proliferator-activated receptors (PPARs), glucagon-like peptide-1 (GLP-1) agonists, sodium/glucose transport protein 2 (SGLT2) inhibitors, farnesoid X receptor (FXR) agonists, probiotics, and symbiotics.

The Role of Psychotherapy in the Treatment of Patients with Non- alcoholic Fatty Liver Disease and Obstructive Sleep Apnea.

Background And Aims: Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease with extensive multi- organ involvement, whose extra-hepatic manifestations include diabetes mellitus type 2, cardiovascular disease, obstructive sleep apnea (OSA), chronic kidney disease, and polycystic ovary syndrome. Our hypothesis was that there was a strong psychological component in NAFLD and OSA suffering patients and that psychotherapy would be helpful in the treatment of the mentioned diseases.

Methods: Of 144 initially selected patients (with NAFLD, obesity and OSA), 32 patients agreed to undergo psychotherapy, and 31 therapy-naive NAFLD and OSA patients agreed to participate as controls.

Are Croatian blood donors obese?

The purpose of this study was to analyze the prevalence of overweight and obesity in healthy blood donors in Primorje-Gorski Kotar County, Croatia, and the relationship between socio-demographic factors, lifestyle and eating habits, and body mass index (BMI), including the association of these factors with overweight and obesity. This cross-sectional study included 1255 healthy individuals aged between 18 and 70 years who donated blood between January 2015 and October 2016 at the Clinical Institute of Transfusion Medicine.

Modeling of Urinary Microbiota Associated With Cystitis.

A decade ago, when the Human Microbiome Project was starting, urinary tract (UT) was not included because the bladder and urine were considered to be sterile. Today, we are presented with evidence that healthy UT possesses native microbiota and any major event disrupting its "equilibrium" can impact the host also. This dysbiosis often leads to cystitis symptoms, which is the most frequent lower UT complaint, especially among women.

The Role of Innate Immunity in the Pathogenesis of Breast Cancer.

Background: Breast carcinoma is the most common malignant disease in the female population and one of the leading causes of death among women worldwide. One crucial hallmark of cancer is chronic inflammation where the immunosuppressive environment is dominant. The immunosuppressive environment is largely achieved by the interaction of tumor cells and infiltrating leukocytes.
