A predicted CRISPR-mediated symbiosis between uncultivated archaea.

CRISPR-Cas systems defend prokaryotic cells from invasive DNA of viruses, plasmids and other mobile genetic elements. Here, we show using metagenomics, metatranscriptomics and single-cell genomics that CRISPR systems of widespread, uncultivated archaea can also target chromosomal DNA of archaeal episymbionts of the DPANN superphylum. Using meta-omics datasets from Crystal Geyser and Horonobe Underground Research Laboratory, we find that CRISPR spacers of the hosts Candidatus Altiarchaeum crystalense and Ca.

Spatio-functional organization in virocells of small uncultivated archaea from the deep biosphere.

Despite important ecological roles posited for virocells (i.e., cells infected with viruses), studying individual cells in situ is technically challenging.

The prevalence of symptoms and its correlation with sex in polish COVID-19 adult patients: Cross-sectional online open survey.

Background: The understanding and treatment of COVID-19 has improved rapidly since December 2019 when SARS-CoV-2 was sequenced. However most papers on its symptomatology focus on hospitalized patients and address only a limited number of major presentations. Although differences depending on sex of COVID-19 patients have been previously confirmed (higher ICU admission and higher death rate for men), no publication has focused on sex-related differences in COVID-19 symptomatology.

Primary nonadherence to medication and its drivers in Poland: findings from the electronic prescription pilot analysis.

Introduction: Primary nonadherence to medication occurs when a patient does not fill a prescription and often leads to suboptimal patient outcomes, lost productivity, and increased net costs. Pilot introduction of electronic prescriptions (e‑prescriptions) in Poland took place in 2018, enabling nationwide assessment of primary nonadherence.

Objectives: To determine the prevalence and drivers of primary nonadherence in Poland.

[Function of the growth hormone axis--insulin-like growth factors--insulin-like growth factor binding proteins in patients with chronic liver diseases].

Up to date have demonstrated that more and more young people are affected by chronic liver diseased. There is a close relationship between the liver and endocrine system as far as hormone inactivation, synthesis of growth factors, proteins binding hormones and proteins binding growth factors in the liver are related. Impairment of the hepatocyte function may lead to disturbed homeostasis of the endocrine system.
