Recent Advances in Peptidoglycan Synthesis and Regulation in Bacteria.

Bacteria must synthesize their cell wall and membrane during their cell cycle, with peptidoglycan being the primary component of the cell wall in most bacteria. Peptidoglycan is a three-dimensional polymer that enables bacteria to resist cytoplasmic osmotic pressure, maintain their cell shape and protect themselves from environmental threats. Numerous antibiotics that are currently used target enzymes involved in the synthesis of the cell wall, particularly peptidoglycan synthases.

Heterogeneous Catalysts for Glycerol Biorefineries: Hydrogenolysis to 1,2-Propylene Glycol.

Research on the use of biomass resources for the generation of energy and chemical compounds is of great interest worldwide. The development and growth of the biodiesel industry has led to a parallel market for the supply of glycerol, its main by-product. Its wide availability and relatively low cost as a raw material make glycerol a basic component for obtaining various chemical products and allows for the development of a biorefinery around biodiesel plants, through the technological integration of different production processes.

Immediate prepectoral breast reconstruction using an ADM with smooth round implants: A prospective observational cohort study.

Prepectoral breast reconstruction using acellular dermal matrices (ADMs) is well established and used in candidates for nipple/skin-sparing mastectomies; it is based on many different matrices and a great variability in breast implant selection. We describe our experience and clinical outcomes using Braxon® ADMs and smooth round breast implants. Females aged 18-80 years who underwent mastectomies with immediate prepectoral reconstruction between April 2019 and April 2021 were prospectively included.

Increased Levels of Circulating Iron-Albumin Complexes in Peripheral Arterial Disease Patients.

Under physiological conditions, extracellular iron circulates in the blood bound to transferrin. As a consequence of several pathologies, the circulating level of a Non-Transferrin Bound pool of Iron (NTBI) increases. The NTBI pool is biologically heterogeneous and represented by iron chelated either by small metabolites (citrate, amino acids, or cofactors) or by serum proteins.

PrkA is an ATP-dependent protease that regulates sporulation in Bacillus subtilis.

In Bacillus subtilis, sporulation is a sequential and highly regulated process. Phosphorylation events by histidine kinases are key points in the phosphorelay that initiates sporulation, but serine/threonine protein kinases also play important auxiliary roles in this regulation. PrkA has been proposed to be a serine protein kinase expressed during the initiation of sporulation and involved in this differentiation process.

Overview of protein phosphorylation in bacteria with a main focus on unusual protein kinases in Bacillus subtilis.

Protein phosphorylation is a post-translational modification that affects protein activity through the addition of a phosphate moiety by protein kinases or phosphotransferases. It occurs in all life forms. In addition to Hanks kinases found also in eukaryotes, bacteria encode membrane histidine kinases that, with their cognate response regulator, constitute two-component systems and phosphotransferases that phosphorylate proteins involved in sugar utilization on histidine and cysteine residues.

Metabolic Control of Cell Elongation and Cell Division in .

To survive and adapt to changing nutritional conditions, bacteria must rapidly modulate cell cycle processes, such as doubling time or cell size. Recent data have revealed that cellular metabolism is a central regulator of bacterial cell cycle. Indeed, proteins that can sense precursors or metabolites or enzymes, in addition to their enzymatic activities involved in metabolism, were shown to directly control cell cycle processes in response to changes in nutrient levels.

High-speed atomic force microscopy highlights new molecular mechanism of daptomycin action.

The increase in speed of the high-speed atomic force microscopy (HS-AFM) compared to that of the conventional AFM made possible the first-ever visualisation at the molecular-level of the activity of an antimicrobial peptide on a membrane. We investigated the medically prescribed but poorly understood lipopeptide Daptomycin under infection-like conditions (37 °C, bacterial lipid composition and antibiotic concentrations). We confirmed so far hypothetical models: Dap oligomerization and the existence of half pores.

α-Galactosidase and Sucrose-Kinase Relationships in a Bi-functional AgaSK Enzyme Produced by the Human Gut Symbiont E1.

Plant α-galactosides belonging to the raffinose family oligosaccharides (RFOs) and considered as prebiotics, are commonly degraded by α-galactosidases produced by the human gut microbiome. In this environment, the E1 symbiont-well-known for various benefit-is able to produce an original AgaSK bifunctional enzyme. This enzyme contains an hydrolytic α-galactosidase domain linked to an ATP dependent extra-domain, specifically involved in the α-galactoside hydrolysis and the phosphorylation of the glucose, respectively.

Uridine diphosphate N-acetylglucosamine orchestrates the interaction of GlmR with either YvcJ or GlmS in Bacillus subtilis.

In bacteria, glucosamine-6-phosphate (GlcN6P) synthase, GlmS, is an enzyme required for the synthesis of Uridine diphosphate N-acetylglucosamine (UDP-GlcNAc), a precursor of peptidoglycan. In Bacillus subtilis, an UDP-GlcNAc binding protein, GlmR (formerly YvcK), essential for growth on non-glycolytic carbon sources, has been proposed to stimulate GlmS activity; this activation could be antagonized by UDP-GlcNAc. Using purified proteins, we demonstrate that GlmR directly stimulates GlmS activity and the presence of UDP-GlcNAc (at concentrations above 0.

Investigation of the phosphorylation of Bacillus subtilis LTA synthases by the serine/threonine kinase PrkC.

Bacillus subtilis possesses four lipoteichoic acid synthases LtaS, YfnI, YvgJ and YqgS involved in the synthesis of cell wall. The crystal structure of the extracellular domain of LtaS revealed a phosphorylated threonine and YfnI was identified in two independent phosphoproteome studies. Here, we show that the four LTA synthases can be phosphorylated in vitro by the Ser/Thr kinase PrkC.

Dual regulation of activity and intracellular localization of the PASTA kinase PrkC during Bacillus subtilis growth.

The activity of the PrkC protein kinase is regulated in a sophisticated manner in Bacillus subtilis cells. In spores, in the presence of muropeptides, PrkC stimulates dormancy exit. The extracellular region containing PASTA domains binds peptidoglycan fragments to probably enhance the intracellular kinase activity.

Characterization of a fiber-less, multichannel optical probe for continuous wave functional near-infrared spectroscopy based on silicon photomultipliers detectors: assessment of primary sensorimotor response.

We report development, testing, and characterization of a multichannel optical probe for continuous wave (CW) functional near-infrared spectroscopy (fNIRS) that relies on silicon photomultipliers (SiPMs) detectors. SiPMs are cheap, low voltage, and robust semiconductor light detectors with performances analogous to photomultiplier tubes (PMTs). In contrast with PMTs, SiPMs allow direct contact with the head and transfer of the analog signals through thin cables greatly increasing the system flexibility avoiding optical fibers.

Simultaneous functional near-infrared spectroscopy and electroencephalography for monitoring of human brain activity and oxygenation: a review.

Multimodal monitoring has become particularly common in the study of human brain function. In this context, combined, synchronous measurements of functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) are getting increased interest. Because of the absence of electro-optical interference, it is quite simple to integrate these two noninvasive recording procedures of brain activity.

Intraoperative Neurological Monitoring With Evoked Potentials During Carotid Endarterectomy Versus Cooperative Patients Under General Anesthesia Technique: A Retrospective Study.

Introduction: The best technique to evaluate contralateral carotid flow during carotid endarterectomy (CEA) is still debated; an accurate detection of efficient contralateral blood flow can avoid unnecessary shunt placement and its complications. The aim of this retrospective observational study was to evaluate and compare the safety and efficacy of general anesthesia with motor-evoked potential and somatosensory-evoked potentials (mSSEP and tcMEP) versus cooperative patients under general anesthesia (CPGA) technique for CEA. Primary outcome was the rate of technical failure.

Rac1 Pharmacological Inhibition Rescues Human Endothelial Dysfunction.

Background: Endothelial dysfunction contributes significantly to the development of vascular diseases. However, a therapy able to reduce this derangement still needs to be identified. We evaluated the effects of pharmacological inhibition of Rac1, a small GTPase protein promoting oxidative stress, in human endothelial dysfunction.

Motor phenotype is not associated with vascular dysfunction in symptomatic Huntington's disease transgenic R6/2 (160 CAG) mice.

Whereas Huntington's disease (HD) is unequivocally a neurological disorder, a critical mass of emerging studies highlights the occurrence of peripheral pathology like cardiovascular defects in both animal models and humans. The overt impairment in cardiac function is normally expected to be associated with peripheral vascular dysfunction, however whether this assumption is reasonable or not in HD is still unknown. In this study we functionally characterized the vascular system in R6/2 mouse model (line 160 CAG), which recapitulates several features of human pathology including cardiac disease.
