Network analysis of depressive and anxiety symptoms with well-being in students during the COVID-19 pandemic: a repeated cross-sectional study.

The university student population is particularly vulnerable to depression, which was identified during the COVID-19 pandemic. Understanding how depressive symptoms are interrelated with mental and physical health in students is essential. The aim of this study was to reveal the network of depressive and anxiety symptoms with respect to well-being (life satisfaction, physical health, physical activity, and perceived stress) during a difficult situation-the COVID-19 pandemic-at two measurement points of different pandemic severities.

Application of Mesoporous Silicas for Adsorption of Organic and Inorganic Pollutants from Rainwater.

Precipitation is an important factor that influences the quality of surface water in many regions of the world. The pollution of stormwater runoff from roads and parking lots is an understudied area in water quality research. Therefore, a comprehensive analysis of the physicochemical properties of rainwater flowing from parking lots was carried out, considering heavy metals and organic micropollutants.

Myo-differentiation reporter screen reveals NF-Y as an activator of PAX3-FOXO1 in rhabdomyosarcoma.

Recurrent chromosomal rearrangements found in rhabdomyosarcoma (RMS) produce the PAX3-FOXO1 fusion protein, which is an oncogenic driver and a dependency in this disease. One important function of PAX3-FOXO1 is to arrest myogenic differentiation, which is linked to the ability of RMS cells to gain an unlimited proliferation potential. Here, we developed a phenotypic screening strategy for identifying factors that collaborate with PAX3-FOXO1 to block myo-differentiation in RMS.

The Artificial Neural Network as a Diagnostic Tool of the Risk of Infection among Patients with Chronic Kidney Disease.

The majority of recently published studies indicate a greater incidence and mortality due to infection (CDI) in patients with chronic kidney disease (CKD). Hospitalization, older age, the use of antibiotics, immunosuppression, proton pump inhibitors (PPI), and chronic diseases such as CKD are responsible for the increased prevalence of infections. The aim of the study is to identify clinical indicators allowing, in combination with artificial intelligence (AI) techniques, the most accurate assessment of the patients being at elevated risk of CDI.

Risk of mortality in COVID-19 patients: a meta- and network analysis.

Understanding the most relevant hematological/biochemical characteristics, pre-existing health conditions and complications in survivors and non-survivor will aid in predicting COVID-19 patient mortality, as well as intensive care unit (ICU) referral and death. A literature review was conducted for COVID-19 mortality in PubMed, Scopus, and various preprint servers (bioRxiv, medRxiv and SSRN), with 97 observational studies and preprints, consisting of survivor and non-survivor sub-populations. This meta/network analysis comprised 19,014 COVID-19 patients, consisting of 14,359 survivors and 4655 non-survivors.

Spontaneous rhythm discrimination in a mammalian vocal learner.

Rhythm and vocal production learning are building blocks of human music and speech. Vocal learning has been hypothesized as a prerequisite for rhythmic capacities. Yet, no mammalian vocal learner but humans have shown the capacity to flexibly and spontaneously discriminate rhythmic patterns.

Clinical Determinants Predicting Infection among Patients with Chronic Kidney Disease.

The majority of recently published studies indicate a greater incidence rate and mortality due to Clostridioides difficile infection (CDI) in patients with chronic kidney disease (CKD). The aim of this study was to assess the clinical determinants predicting CDI among hospitalized patients with CKD and refine methods of prevention. We evaluated the medical records of 279 patients treated at a nephrological department with symptoms suggesting CDI, of whom 93 tested positive for CDI.

Can harbor seals () discriminate familiar conspecific calls after long periods of separation?

The ability to discriminate between familiar and unfamiliar calls may play a key role in pinnipeds' communication and survival, as in the case of mother-pup interactions. Vocal discrimination abilities have been suggested to be more developed in pinniped species with the highest selective pressure such as the otariids; yet, in some group-living phocids, such as harbor seals (), mothers are also able to recognize their pup's voice. Conspecifics' vocal recognition in pups has never been investigated; however, the repeated interaction occurring between pups within the breeding season suggests that long-term vocal discrimination may occur.

Expression and role of resistin on steroid secretion in the porcine corpus luteum.

Resistin plays an important role in adipogenesis, obesity, insulin resistance, and reproduction. Previous studies showed resistin action on ovarian follicular cells; however, whether resistin regulates steroid secretion in luteal cells is still unknown. Our aim was first to determine the expression of resistin and its potential receptors (tyrosine kinase-like orphan receptor 1 (ROR1) and toll-like receptor 4 (TLR4)) in the porcine corpus luteum (CL), regulation of its expression, effect on kinases phosphorylation, and luteal steroidogenesis.

Microstructure and Mechanical Properties of Modern 11%Cr Heat-Resistant Steel Weld Joints.

In addition to good high-temperature creep resistance and adequate heat resistance, steels for the power industry must have, among other things, good weldability. Weldability of such steels is one of the criteria determining whether or not the material is suitable for applications in the power industry. Therefore, when materials such as martensitic steel Thor 115 (T115) are introduced into the modern power industry, the quality and properties of welded joints must be assessed.

Effect of Transgenesis on mRNA and miRNA Profiles in Cucumber Fruits Expressing .

Transgenic plants are commonly used in breeding programs because of the various features that can be introduced. However, unintended effects caused by genetic transformation are still a topic of concern. This makes research on the nutritional safety of transgenic crop plants extremely interesting.

The Effect of Service on Microstructure and Mechanical Properties of HR3C Heat-Resistant Austenitic Stainless Steel.

The physical metallurgical tests were performed on the test samples made of HR3C steel, taken from a section of a pipeline in the as-received condition and after approximately 26,000 h of service at 550 °C. In the as-received condition, the test material had austenitic microstructure with numerous large primary Z-phase precipitates inside the grains. The service of the test steel mainly contributed to the precipitation processes inside the grains and at the grain boundaries.

Activation of Stimulator of Interferon Genes (STING) and Sjögren Syndrome.

Sjögren syndrome (SS), a chronic autoimmune disorder causing dry mouth, adversely affects the overall oral health in patients. Activation of innate immune responses and excessive production of type I interferons (IFNs) play a critical role in the pathogenesis of this disorder. Recognition of nucleic acids by cytosolic nucleic acid sensors is a major trigger for the induction of type I IFNs.

Immune response against the coiled coil domain of Sjögren's syndrome associated autoantigen Ro52 induces salivary gland dysfunction.

Objectives: The structural domains of Ro52, termed the RING, B-box, coiled coil (CC) and B30.2/SPRY are targets of anti-Ro52 in multiple autoimmune disorders. In Sjögren's syndrome patients, the presence of anti-Ro52 is associated with higher disease severity, and in mice, they induce salivary gland hypofunction.

A unique defect - persistent posterior cloaca: An example of staged genito-urinary and digestive tract reconstruction with an alternative vaginal creation using the urinary bladder wall.

We present a case of a girl with an extremely rare, posterior type of persistent cloaca, which was associated with other abnormalities, including an undeveloped vulva and vagina, agenesis of the right kidney, secondary obstructive megaureter, unicornate uterus, persisted tailgut, sacral bone hypoplasia, and pubic symphysis hypertrophy. An operative approach was as follows: (i) colostomy and ureterocutaneostomy; (ii) creation of an ileal conduit with antirefluxing uretero-ileal anastomosis, and then creation of a continent catheterizable ileal reservoir; (iii) anastomosis of sigmoid colon to rectal stump; and (iv) vaginal and external genital reconstruction. Because of abnormal anatomical conditions where the uterus was situated adjacent to the open, incompetent bladder neck, we decided to create a vagina using the bladder wall instead of the bowel segment.

Overcoming the membrane barrier: Recruitment of γ-glutamyl transferase for intracellular release of metabolic cargo from peptide vectors.

Semipermeable membranes of cells frequently pose an obstacle in metabolic engineering by limiting uptake of substrates, intermediates, or xenobiotics. Previous attempts to overcome this barrier relied on the promiscuous nature of peptide transport systems, but often suffered from low versatility or chemical instability. Here, we present an alternative strategy to transport cargo molecules across the inner membrane of Escherichia coli based on chemical synthesis of a stable cargo-peptide vector construct, transport through the peptide import system, and efficient intracellular release of the cargo by the promiscuous enzyme γ-glutamyl transferase (GGT).
