Synthetic Chameleon Turns into Oximes, Nitrones, and Hydroxylamines when Exposed to Blue Light.

A metal-free, user-friendly photochemical transformation of nitroalkanes to oximes, nitrones, and hydroxylamines has been developed. The visible-light-induced reactions are catalyzed by the readily available photoredox organocatalyst 4CzIPN and use inexpensive amines as reductants. Broad in scope and tolerant of multiple functional groups and heterocycles, the transformation proceeds under mild conditions.

NSCLC: from tumorigenesis, immune checkpoint misuse to current and future targeted therapy.

Non-small cell lung cancer (NSCLC) is largely promoted by a multistep tumorigenesis process involving various genetic and epigenetic alterations, which essentially contribute to the high incidence of mortality among patients with NSCLC. Clinical observations revealed that NSCLC also co-opts a multifaceted immune checkpoint dysregulation as an important driving factor in NSCLC progression and development. For example, a deregulated PI3K/AKT/mTOR pathway has been noticed in 50-70% of NSCLC cases, primarily modulated by mutations in key oncogenes such as ALK, EGFR, KRAS, and others.

In vitro comparison of two food choice methodologies for necrophagous species of the genus Thanatophilus (Coleoptera: Staphylinidae: Silphinae).

To accurately model the food webs, we need to acquire precise data on food ecology of the interacting species. This allows better understanding of the trophic interactions and for the necrophagous species this information could be used in medico-legal investigations. For this reason, we recently proposed standardized laboratory methodology to assess the foraging strategies based on parallel testing of 2 food items (meat, dead larvae) (Jakubec et al.

The effectiveness of glucocorticoid treatment in post-COVID-19 pulmonary involvement.

Rationale: Persistent respiratory symptoms following Coronavirus Disease 2019 (COVID-19) are associated with residual radiological changes in lung parenchyma, with a risk of development into lung fibrosis, and with impaired pulmonary function. Previous studies hinted at the possible efficacy of corticosteroids (CS) in facilitating the resolution of post-COVID residual changes in the lungs, but the available data is limited.

Aim: To evaluate the effects of CS treatment in post-COVID respiratory syndrome patients.

All insects matter: a review of 160 entomology cases from 1993 to 2007 in Switzerland-part I (Diptera).

Lung malignancies have a substantial impact on cancer incidence and mortality worldwide. Even though many factors involved in the development of the disease are known, many questions remain unanswered. Previous studies suggest that the intestinal microbiota may have a role in developing malignant diseases.

The Effects of Antibiotics on the Development and Treatment of Non-Small Cell Lung Cancer.

There have been studies on antibiotic use concerning lung cancer and its potential impact on carcinogenesis and microbiome. However, subsequent research has failed to support these associations consistently. In terms of the potential carcinogenic of antibiotics on lung cancer, the available evidence has not been sufficient to draw any definitive conclusions.

How to store a beetle larva? Comparing temporal effects of common fluid preservation methods on color, shape, and DNA quality.

Proper fixing and long-term preservation of entomological evidence are essential in collections and research and crucial in applied fields such as forensic entomology. Incorrectly stored samples may lose important morphological features over time, rendering molecular analyses exceedingly difficult. The most effective method for preserving soft samples such as larvae is fluid preservation.

[Respiratory manifestations of post-COVID syndrome].

Overcoming infection with coronavirus disease 2019 (COVID-19) can lead to the persistence of various symptoms in some patients. The complex of symptoms causally related to severe acute respiratory coronavirus 2 infection is called post-COVID syndrome. One of the most common respiratory complications is pulmonary fibrosis, especially after critical course of the disease.

Evaluation of genetic risk, its clinical manifestation and disease management based on 18 susceptibility gene markers among West-Slavonic patients with sarcoidosis.

Sarcoidosis is a heterogenous, multisystemic inflammatory disease that primarily affects lungs. In this study, we multiplex genotyped 18 single-nucleotide polymorphisms (SNPs) to replicate the findings from previous genome-wide association studies (GWAS) and candidate gene studies, and extended analyses to different clinical manifestations (Löfgren's syndrome and chest X-ray [CXR] stages) including treatment response among West-Slavonic subjects (564 sarcoidosis patients and 301 healthy controls). We confirm the replication (with Bonferroni's correction) of ANXA11 rs1049550 as protective variant for sarcoidosis (odds ratio [OR] = 0.

Hypercapnic respiratory failure - review.

This review summarizes the issue of acute hypercapnic respiratory failure. Acute respiratory failure is a condition in which the respiratory system is unable to fulfill its basic function, i.e.

Long-Term Follow-Up of Patients Needing Extracorporeal Membrane Oxygenation Following a Critical Course of COVID-19.

Introduction: Severe respiratory failure is one of the most serious complications of coronavirus disease 2019 (COVID-19). In a small proportion of patients, mechanical ventilation fails to provide adequate oxygenation and extracorporeal membrane oxygenation (ECMO) is needed. The surviving individuals need long-term follow-up as it is not clear what their prognosis is.

The use of extracorporeal membrane oxygenation in the treatment of critical course of pneumonia.

Extracorporeal membrane oxygenation is the highest form of resuscitation care in management of patients with respiratory failure. In the case of acute respiratory distress syndrome, the veno-venous setting is more often used. ECMO support enables, in case of lung function failure, to obtain the necessary time for the onset of the causal treatment effect or is used as a bridge to transplantation Mortality of the patients varies according to the underlying cause and presence of risk factors (e.

The Impact of Diet and Photoperiodism on the Life History of Thanatophilus sinuatus (Coleoptera: Silphidae).

The forensically important genus Thanatophilus Leach, 1815 (Coleoptera: Silphidae) is a widespread group of carrion beetles that occupies the Holarctic and Afrotropical realms. It has recently received more recognition, as its species are frequently detected on large carrion, including humans, and can be useful in estimating the time of colonization (TOC) and the post-mortem interval (PMI). The immature stages of Thanatophilus sinuatus (Fabricius, 1775) were reared on three different meat diets (pork liver, pork muscle, and chicken muscle).

Click and Detect: Versatile Ampicillin Aptasensor Enabled by Click Chemistry on a Graphene-Alkyne Derivative.

Tackling the current problem of antimicrobial resistance (AMR) requires fast, inexpensive, and effective methods for controlling and detecting antibiotics in diverse samples at the point of interest. Cost-effective, disposable, point-of-care electrochemical biosensors are a particularly attractive option. However, there is a need for conductive and versatile carbon-based materials and inks that enable effective bioconjugation under mild conditions for the development of robust, sensitive, and selective devices.

Sex transition from female to male as a risk factor for sleep-disordered breathing.

Aim: The female-to-male (FtM) sex transition requires lifelong supplementation with male sex hormones, resulting in high prevalence of weight gain, fat redistribution and other metabolic changes. Although sleep-disordered breathing (SDB) data for this group of patients are very limited, increased prevalence is expected. We report a mini-series of six case reports of FtM transsexuals treated in our centre.

Risk of Severe COVID-19 in Non-Adherent OSA Patients.

Background: Patients with obstructive sleep apnoea (OSA) are at increased risk of severe course of COVID-19. Vaccination remains to be the most effective prevention of complicated courses of infection. The best contemporary conservative treatment of OSA is continuous positive airway pressure (CPAP) therapy.

Network Analysis for Uncovering the Relationship between Host Response and Clinical Factors to Virus Pathogen: Lessons from SARS-CoV-2.

Analysing complex datasets while maintaining the interpretability and explainability of outcomes for clinicians and patients is challenging, not only in viral infections. These datasets often include a variety of heterogeneous clinical, demographic, laboratory, and personal data, and it is not a single factor but a combination of multiple factors that contribute to patient characterisation and host response. Therefore, multivariate approaches are needed to analyse these complex patient datasets, which are impossible to analyse with univariate comparisons (e.

[Chronic lung diseases and sleep].

Sleep is vitally important part of our life. Its quality and quantity influence all physiological processes in our organism. The relationship between the lung diseases and sleep is bidirectional - the lack of quality sleep worsens the compensation and the course of the diseases and in the same time chronic lung diseases are negatively affecting sleep quality.

[Pulmonary complications following COVID-19 infection].

In the relatively short period of time since December 2019, hundreds of millions of people globally have been infected with SARS-CoV-2, irrespective of their age, gender or ethnicity. Over that time, numerous mutations of various degrees of virulence and pathogenicity have occurred. The course of COVID-19 infection, an acute disease caused by the virus, is rather varied, ranging from asymptomatic or symptoms of common viral respiratory diseases to critical, with multiorgan failure and high mortality in high-risk patients.
