Streptococcus pyogenes (Group A streptococcus; GAS) is an important human pathogen responsible for mild to severe, life-threatening infections. GAS expresses a wide range of virulence factors, including the M family proteins. The M proteins allow the bacteria to evade parts of the human immune defenses by triggering the formation of a dense coat of plasma proteins surrounding the bacteria, includi

This study explores the use of manganese ore, iron-carbon particles (Fe-C), and gravel as anode fillers in electroactive constructed wetlands (ECWs) to treat wastewater containing pharmaceuticals and personal care products (PPCPs) including ciprofloxacin (CIP), ofloxacin (OFL), and naproxen (NPX), while also assessing bioelectricity production. Although the presence of PPCPs reduced pollutant remo

Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation. SpeB activity depends on the transformation from an inactive precursor, zymogen, into a mature proteinase. We show that

In the present study, two types of micro-pin–fin configurations were fabricated on silicon surfaces by a dry etching method, i.e., staggered pin fins (#1) and aligned pin fins with empty areas (#2). The micro-pin–fin surfaces were then further modified by depositing FeMn oxide nanoparticles (∼35 nm) electrostatically for 8 h and 16 h, respectively, namely #1-8h, #1-16h, #2-8h and #2-16h. Subcooled

Recent epidemiological data on diseases caused by beta-hemolytic streptococci belonging to Lancefield group C and G ( GCS, GGS) underline that they are an emerging threat to human health. Among various virulence factors expressed by GCS and GGS isolates from human infections, M and M-like proteins are considered important because of their anti-phagocytic activity. In addition, protein G has been i

Hormone-sensitive lipase (HSL) is mainly present in adipose tissue where it hydrolyses diacylglycerol. Although expression of HSL has also been reported in the brain, its presence in different cellular compartments is uncertain, and its role in regulating brain lipid metabolism remains hitherto unexplored. We hypothesized HSL might play a role in regulating the availability of bioactive lipids nec

The increase of obesity and type 2 diabetes on a global scale has increased the interest in how to counteract this epidemic. Improved lifestyle in general is a fundamental approach, but other remedies such as specific weight reduction or diabetes preventive drugs and surgery have also been tested. One problem to understand is what really happens after weight loss. Ongoing studies will try to addre

Eftersom stater i hög grad har misslyckats med att ta den globala uppvärmningen seriöst, har istället privata individer och miljöorganisationer konfronterat dem som bidrar till den. Genom att föra de som släpper ut växthusgaser inför rätta hoppas kärandena kunna stoppa den nuvarande kursen mot förödande klimatförändring. Klimattvister kan rikta sig mot både regeringar och företag, men i just tvistWhere states have failed to take the threat of global warming seriously, private individuals and environmental organizations have confronted those contributing to it. By bringing the emitters to court, litigants all over the world hope to put an end to the current trajectory towards dangerous climate change. Within the field of climate litigation, both governments and corporations are targeted. Th

Survivors after cardiac arrest (CA) exhibits a systemic inflammatory response as part of post-cardiac arrest syndrome (PCAS). We investigated the association between systemic inflammation and severity of PCAS and whether level of targeted temperature management (TTM) modifies level of the inflammatory response.

Tumor-associated macrophages (TAMs) have emerged as key players in tumor immunology but demonstrate a continuum of functional states being either tumor suppressive or promoting. Moreover, chemotherapeutic agents have been shown to alter the tumor microenvironment. Perioperative chemotherapy is a standard treatment option for resectable esophageal and gastric (EG) adenocarcinoma. The aim of this st
