N-Thio-β-lactams targeting L,D-transpeptidase-2, with activity against drug-resistant strains of Mycobacterium tuberculosis

Effective treatment of tuberculosis is frequently hindered by the emerging antimicrobial resistance of Mycobacterium tuberculosis. The present study evaluates monocyclic β-lactam compounds targeting the mycobacterial cell wall remodeling. Novel N-thio-β-lactams were designed, synthesized, and characterized on the L,D-transpeptidase-2, a validated target in M. tuberculosis. The candidates were eval

The structure of the N-terminal module of the cell wall hydrolase RipA and its role in regulating catalytic activity

RipA plays a vital role during cell division of Mycobacterium tuberculosis by degrading the cell wall peptidoglycan at the septum, allowing daughter cell separation. The peptidoglycan degrading activity relies on the NlpC/P60 domain, and as it is potentially harmful when deregulated, spatial and temporal control is necessary in this process. The N-terminal domain of RipA has been proposed to play

Binding and processing of β-lactam antibiotics by the transpeptidase LdtMt2 from Mycobacterium tuberculosis

β-lactam antibiotics represent a novel direction in the chemotherapy of tuberculosis that brings the peptidoglycan layer of the complex mycobacterial cell wall in focus as a therapeutic target. Peptidoglycan stability in Mycobacterium tuberculosis, especially during infection, relies on the nonconventional peptide cross-links formed by l,d-transpeptidases. These enzymes are known to be inhibited b

Long term sustained attention alters dynamic functional connectivity patterns

Mental fatigue has attracted much attention from researchers as it plays a key role in performance efficiency and safety situations. Functional connectivity analysis using graph theory is an effective method for revealing changes in cognition resources influenced by mental fatigue. Previous studies have revealed that functional networks are dynamically reorganized. Therefore, it is critical to exp

Isolation of nucleic acids using a polycationic polymer as precipitation agent

The present invention relates to a method of isolating a desired nucleic acid from a biological solution, which method comprises to selectively precipitate the desired nucleic acid by adding a polycationic precipitating agent to the solution and allowing it to form a complex with said nucleic acid, wherein the precipitating agent is a highly charged linear polymer that comprises quaternary amino g

Lectin-containing separation agent

A separation agent composed of a water unsoluble solid substance with a covalently bound lectin. Said solid substance is structurally composed of a water unsoluble silica or silicate material as basic material and, via a linkage to silicon atoms in the silica or silicate material, a covalently bound lectin.

Separation agent

A chromatographic separation agent composed of a water unsoluble solid substance showing dihydroxybo ryl groups. Said solid substance is structurally composed of a water unsoluble silica or silicate material as basic structure and, via a linkage to silicon atoms in the silica or silicate material, covalently bound dihydrox yboryl groups in acid, salt or complex form.

Analyzing Questions About Alcohol in Pregnancy Using Web-Based Forum Topics : Qualitative Content Analysis

Background:Prenatal alcohol exposure represents a substantial public health concern as it may lead to detrimental outcomes, including pregnancy complications and fetal alcohol spectrum disorder. Although UK national guidance recommends abstaining from alcohol if pregnant or planning a pregnancy, evidence suggests that confusion remains on this topic among members of the public, and little is known

Unravelling the economic impact of climate change in Vietnam's Mekong River Delta and Southeast region

Vietnam faces a heightened susceptibility to natural disasters stemming from climate change, yet the impact of these disasters varies markedly across its regions. Consequently, it is imperative to scrutinize the climatic factors affecting the regional economy, with a particular dearth of research addressing the nexus between natural threats and the economies of the Mekong River Delta and the South

Mapping the path to a decarbonised agri-food products : A hybrid geographic information system and life cycle inventory methodology for assessing sustainable agriculture

The development of a decarbonised food industry will depend on a sustainable agricultural system where embodied food product greenhouse gas emissions (GHG) can be associated with agricultural production. The results presented demonstrate how physically mapping agri-production provides regional carbon footprints so practice that reduces GHG emissions become strategic rather than random. Different a

The Role of Translation in Enacting Multiscalar Climate Action : Insights from European Christian Faith-Based Actors

The complex nature of climate change requires action at different scales and in different ways, but questions remain around how to produce climate action that is both multi-scalar and joined up. Here we explore this question by adopting a relational approach to studying climate action by faith-based actors, who increasingly play an active role campaigning on climate action. Drawing on qualitative

Stuck in the playground : a (failed) organizational entrepreneuring process

Collaborative spaces such as fab labs, incubators, and coworking spaces have become a worldwide phenomenon based on their promise of fostering creativity and entrepreneurship. Mature, large organizations have also tried to benefit from this by creating such spaces in-house. This paper studies a failed attempt to create one such space in a large bureaucratic organization. Our study shows that succe

Newborn Screening for High-Risk Congenital Heart Disease by Dried Blood Spot Biomarker Analysis.

Importance Congenital heart disease (CHD) is the most common human organ malformation, affecting approximately 1 of 125 newborns globally.Objectives Assessing the performance of 2 diagnostic tests using minimal amounts of dried blood spots (DBS) to identify high-risk CHD compared with controls in a Swedish cohort of neonates.Design, Setting, and Participants This diagnostic study took place in Swe

Knut Wicksell åtalas för hädelse

Podcast "Öppet fall" från Lunds universitet, Juridiska fakulteten: Knut Wicksell är en världsberömd nationalekonom som var professor i Lund vid början av 1900-talet. Han var en progressiv samhällsdebattör som förespråkade jämställdhet mellan könen, och hans livskamrat Anna Bugge Wicksell var Sveriges första kvinnliga diplomat. 1908 håller Wicksell ett föredrag där han angriper kyrkan och raljerar
