Outcome of Liver Retransplantation in Patients With Primary Sclerosing Cholangitis.

Background And Aims: Primary sclerosing cholangitis (PSC) is among the most common indications for liver transplantation in the Nordic countries and with an increasing trend in Europe and North America. Due to post-transplant complications and high prevalence of disease recurrence this group is at risk of requiring retransplantation (re-LTX). Results from re-LTX for PSC are not extensively studied and there is a lack of knowledge regarding prognosis after re-LTX in this population.

The effect of nanoceria on the alginate-gum arabic crosslinking mechanism and in vitro behavior as a wound dressing.

Medical practice has proven that chronic wounds can be treated successfully if the dressing is chosen according to the healing phase of the wound. Correct intervention from the hemostasis and inflammatory phase can prevent oxidative stress and ensure optimal conditions for healing. It is important to design a new wound dressing that does not cause additional injury, has an antioxidant effect, removes dead cells, and promotes wound healing.

Development and in vitro evaluation of a lignin-PLGA nanocarrier for florfenicol delivery.

Florfenicol (FF) is a widely used antimicrobial in veterinary medicine because of its broad antimicrobial activity, although it has certain limitations and raises concerns about the development of antimicrobial resistance genes. These limitations highlight the need to explore novel drug with controlled release systems to enhance the therapeutic efficacy of FF, while minimizing the potential for resistance development. This study introduces an innovative approach for the design, synthesis, and evaluation of lignin-poly(lactic-co-glycolic) acid (PLGA)-FF nanoparticles.

Fpa (YlaN) is an iron(II) binding protein that functions to relieve Fur-mediated repression of gene expression in .

Iron (Fe) is a trace nutrient required by nearly all organisms. As a result of the demand for Fe and the toxicity of non-chelated cytosolic ionic Fe, regulatory systems have evolved to tightly balance Fe acquisition and usage while limiting overload. In most bacteria, including the mammalian pathogen , the ferric uptake regulator (Fur) is the primary transcriptional regulator controlling the transcription of genes that code for Fe uptake and utilization proteins.

Analgesia and peripheral c-fiber modulation by selective Nav1.8 inhibition in rhesus.

Voltage-gated sodium (Nav) channels present untapped therapeutic value for better and safer pain medications. The Nav1.8 channel isoform is of particular interest because of its location on peripheral pain fibers and demonstrated role in rodent preclinical pain and neurophysiological assays.

ATH434, a promising iron-targeting compound for treating iron regulation disorders.

Cytotoxic accumulation of loosely bound mitochondrial Fe2+ is a hallmark of Friedreich's Ataxia (FA), a rare and fatal neuromuscular disorder with limited therapeutic options. There are no clinically approved medications targeting excess Fe2+ associated with FA or the neurological disorders Parkinson's disease and Multiple System Atrophy. Traditional iron-chelating drugs clinically approved for systemic iron overload that target ferritin-stored Fe3+ for urinary excretion demonstrated limited efficacy in FA and exacerbated ataxia.

White-coat effect and masked hypertension in patients with high-normal office blood pressure: results of the Hungarian ABPM Registry.

Objective: Blood pressure (BP) lowering therapy in hypertension can markedly reduce the risk of cardiovascular diseases. In case of high-normal office blood pressure (oBP), the initiation of antihypertensive medication is recommended by guidelines in patients with very high cardiovascular risk. The aims of this study were to evaluate the presence of white-coat high-normal BP (WhHNBP) and masked hypertension in high-normal oBP and to explore the prevalence of untreated very high cardiovascular risk patients.

C-peptide: an essential ally in microvascular complications of type 2 diabetes mellitus and obesity.

Background: In order to investigate microvascular complications in metabolic diseases, we aimed to investigate cerebral and peripheral microcirculation in relation to peripheral neuropathy and laboratory biomarkers in type 2 diabetes mellitus (T2DM) and obesity.

Methods: Based on the degree of neuropathy (NP), study participants (40 T2DM and 30 obese individuals) were classified into no-NP, mild-NP and severe-NP subgroups. After the injection of Technetium-99 m hexamethylpropylene amine oxime, both T2DM and obese participants underwent single-photon emission computed tomography/computed tomography ([99mTc]Tc-HMPAO SPECT/CT) and SPECT-only examinations to assess lower limb and brain perfusion; respectively.

Decrease due to pollution in the rhizosphere microbial diversity can be amended by supplementation from adapted plants of another species.

Manipulating the rhizosphere microbiome to enhance plant stress tolerance is an environmentally friendly technology and a renewable resource to restore degraded environments. Here we suggest a sustainable bioremediation strategy on the example of Stebnyk mine tailings storage. We consider Salicornia europaea rhizosphere community, and the ability of the phytoremediation plant Salix viminalis to recruit its beneficial microbiome to mediate the pollution stress at the Stebnyk mine tailings storage.

May Measurement Month 2021: an analysis of blood pressure screening results from Hungary.

Elevated blood pressure (BP) is the most important risk factor for cardiovascular diseases (CVDs), which are still the leading cause of mortality in Hungary. Therefore, screening programmes identifying subjects with hypertension have an important role in CVD prevention. In 2017, the International Society of Hypertension initiated May Measurement Month (MMM) aimed at raising awareness of elevated BP.

Gastrointestinal Perforation with Blunt Abdominal Trauma in Children.

Gastrointestinal tract perforation is uncommon in children, accounting for <10% of cases of blunt abdominal trauma. Diagnosis of bowel perforation in children can be challenging due to poor diagnostic imaging accuracy. Intra-abdominal free air is found only in half of the children with bowel perforation.

TiO-Alginate-Chitosan-Based Composites for Skin Tissue Engineering Applications.

The UV-B component of sunlight damages the DNA in skin cells, which can lead to skin cancer and premature aging. Therefore, it is necessary to use creams that also contain UV-active substances. Many sunscreens contain titanium dioxide due to its capacity to absorb UV-B wavelengths.

Impact of Fat Distribution and Metabolic Diseases on Cerebral Microcirculation: A Multimodal Study on Type 2 Diabetic and Obese Patients.

: Since metabolic diseases and atherosclerotic vascular events are firmly associated, herein we investigate changes in central microcirculation and atherosclerosis-related body fat distribution in patients with type 2 diabetes mellitus and obesity. Resting brain perfusion single-photon emission computed tomography (SPECT) imaging with Technetium-99m hexamethylpropylene amine oxime ([Tc]Tc-HMPAO SPECT) was performed, and the breath-holding index (BHI) and carotid intima-media thickness (cIMT) were measured to characterise central microcirculation. Besides CT-based abdominal fat tissue segmentation, C-peptide level, glycaemic and anthropometric parameters were registered to search for correlations with cerebral blood flow and vasoreactivity.

Central Causation of Autism/ASDs via Excessive [Ca]i Impacting Six Mechanisms Controlling Synaptogenesis during the Perinatal Period: The Role of Electromagnetic Fields and Chemicals and the NO/ONOO(-) Cycle, as Well as Specific Mutations.

The roles of perinatal development, intracellular calcium [Ca]i, and synaptogenesis disruption are not novel in the autism/ASD literature. The focus on six mechanisms controlling synaptogenesis, each regulated by [Ca]i, and each aberrant in ASDs is novel. The model presented here predicts that autism epidemic causation involves central roles of both electromagnetic fields (EMFs) and chemicals.

SARS-CoV-2 clade dynamics and their associations with hospitalisations during the first two years of the COVID-19 pandemic.

Background: The COVID-19 pandemic was characterised by rapid waves of disease, carried by the emergence of new and more infectious SARS-CoV-2 virus variants. How the pandemic unfolded in various locations during its first two years has yet to be sufficiently covered. To this end, here we are looking at the circulating SARS-CoV-2 variants, their diversity, and hospitalisation rates in Estonia in the period from March 2000 to March 2022.
