Inhibition of biofilm formation and preformed biofilm in by resveratrol, chlorhexidine and benzalkonium: modulation of efflux pump activity.

Introduction: The persistence of in the contaminated environment is sustained by tolerance to biocides and ability to growth as biofilm. The aim of the study was to analyze the susceptibility of biofilms to chlorhexidine (CHX) and benzalkonium (BZK) biocides and the ability of natural monomeric stilbenoid resveratrol (RV) to modulate the phenomenon.

Methods: Biofilm formation and preformed biofilm were tested by Crystal violet and tetrazolium salt reduction assay, respectively.

Remodeling the Inflammatory and Immunosuppressive Tumor Microenvironment for Enhancing Antiangiogenic Gene Therapy of Colorectal Cancer.

Fusobacterium nucleatum (Fn), as an intestinal pathogenic bacterium, is closely related to the occurrence, progression, and limited therapeutic efficacy of colorectal cancer (CRC). The presence of Fn within CRC communities induces an inflammatory and immunosuppressive microenvironment while promoting new vessel formation. Therefore, developing novel methods to efficiently eliminate Fn and enhance the therapeutic outcomes against Fn-associated CRC is of great significance.

Patient Reported Outcomes Due to Bladder Neck Obstruction in Women Treated With Botulinum Toxin A Injection.

Introduction: Primary bladder neck obstruction (BNO) occurs when the bladder neck fails to open during voiding, causing urinary symptoms despite no anatomic obstruction. The cause of BNO is unclear but may involve neurogenic dysregulation related to the sympathic nervous system such as upper motor neuron lesion or peripheral autonomic neuropathy (small fiber neuropathy (SFN)). Another etiology can incuded increased sympathetic tone secondary to anxiety or stress conditons.

Direct analysis by ultra-high-resolution mass spectrometry of lipid A and phospholipids from Acinetobacter baumannii cells.

Acinetobacter baumannii, classified as priority number one by the World Health Organization (WHO), is an opportunistic pathogen responsible for infection and is able to develop antibiotic resistance easily. Membranes are bacteria's first line of defense against external aggression, such as antibiotics. A chemical modification of a lipid family or a change in lipid composition can lead to resistance to antibiotics.

Lipidome of Acinetobacter baumannii antibiotic persister cells.

Persister cells constitute a bacterial subpopulation able to survive to high concentrations of antibiotics. This phenotype is temporary and reversible, and thus could be involved in the recurrence of infections and emergence of antibiotic resistance. To better understand how persister cells survive to such high antibiotic concentration, we examined changes in their lipid composition.

Anatomical Location of the Vesical Branches of the Inferior Hypogastric Plexus in Human Cadavers.

We have demonstrated in canines that somatic nerve transfer to vesical branches of the inferior hypogastric plexus (IHP) can be used for bladder reinnervation after spinal root injury. Yet, the complex anatomy of the IHP hinders the clinical application of this repair strategy. Here, using human cadavers, we clarify the spatial relationships of the vesical branches of the IHP and nearby pelvic ganglia, with the ureteral orifice of the bladder.

Antibiofilm and Antivirulence Properties of 6-Polyaminosteroid Derivatives against Antibiotic-Resistant Bacteria.

The emergence of multi-drug resistant pathogens is a major public health problem, leading us to rethink and innovate our bacterial control strategies. Here, we explore the antibiofilm and antivirulence activities of nineteen 6-polyaminosterol derivatives (squalamine-based), presenting a modulation of their polyamine side chain on four major pathogens, i.e.

Sacral Tarlov perineurial cysts: a systematic review of treatment options.

Tarlov perineurial spinal cysts (TCs) are an underrecognized cause of spinal neuropathic symptoms. TCs form within the sensory nerve root sleeves, where CSF extends distally and can accumulate pathologically. Typically, they develop at the sacral dermatomes where the nerve roots are under the highest hydrostatic pressure and lack enclosing vertebral foramina.

Using Targeted Nano-Antibiotics to Improve Antibiotic Efficacy against Infections.

The poor bioavailability of antibiotics at infection sites is one of the leading causes of treatment failure and increased bacterial resistance. Therefore, developing novel, non-conventional antibiotic delivery strategies to deal with bacterial pathogens is essential. Here, we investigated the encapsulation of two fluoroquinolones, ciprofloxacin and levofloxacin, into polymer-based nano-carriers (nano-antibiotics), with the goal of increasing their local bioavailability at bacterial infection sites.

6-Polyaminosteroid Squalamine Analogues Display Antibacterial Activity against Resistant Pathogens.

A series of 6-polyaminosteroid analogues of squalamine were synthesized with moderate to good yields and evaluated for their antimicrobial properties against both susceptible and resistant Gram-positive (vancomycin-resistant and methicillin-resistant ) and Gram-negative (carbapenem-resistant and bacterial strains. Minimum inhibitory concentrations against Gram-positive bacteria ranged from 4 to 16 µg/mL for the most effective compounds, and , and showed an additive or synergistic effect with vancomycin or oxacillin. On the other hand, the derivative , which carries a spermine moiety like that of the natural trodusquemine molecule, was found to be the most active derivative against all the resistant Gram-negative bacteria tested, with an MIC value of 16 µg/mL.

Lysine Trimethylation in Planktonic and Pellicle Modes of Growth in .

Over the past 30 years, has been described as an important nosocomial pathogen due to frequent ventilator-associated infections. Many biological processes of remain elusive, such as the formation of an air-liquid biofilm (pellicle). Several studies demonstrated the importance of post-translational modifications (PTMs) in physiology.

Restoring bladder function using motor and sensory nerve transfers: a cadaveric feasibility study.

Objective: Bladder dysfunction after nerve injury has a variable presentation, and extent of injury determines whether the bladder is spastic or atonic. The authors have proposed a series of 3 nerve transfers for functional innervation of the detrusor muscle and external urethral sphincter, along with sensory innervation to the genital dermatome. These transfers are applicable to only cases with low spinal segment injuries (sacral nerve root function is lost) and largely preserved lumbar function.

Non-Surgical Management of Chronic Pelvic Pain in Females.

Purpose Of Review: The purpose of this paper is to review the most recent literature on non-surgical therapeutic options for chronic pelvic pain in females.

Recent Findings: Chronic pelvic pain can arise from virtually any organ system in the human body. If a precise etiology is identified, the management of chronic pelvic pain can be tailored accordingly.

MacAB-TolC Contributes to the Development of Biofilm at the Solid-Liquid Interface.

has emerged as one of the most problematic bacterial pathogens responsible for hospital-acquired and community infections worldwide. Besides its high capacity to acquire antibiotic resistance mechanisms, it also presents high adhesion abilities on inert and living surfaces leading to biofilm development. This lifestyle confers additional protection against various treatments and allows it to persist for long periods in various hospital niches.

Urodynamic autonomic bladder dysfunction in women with complex chronic pelvic pain is associated with small fiber polyneuropathy.

Aims: Small fiber neuropathy/polyneuropathy (SFN) has been found to be present in 64% of complex (refractory or multisystem) chronic pelvic pain (CPP) patients. The small fiber dysfunction seen in SFN can negatively impact autonomic control of micturition in addition to pain. This study investigated the clinical association of autonomic dysfunction (detrusor underactivity and primary bladder neck obstruction [BNO]) on video urodynamics (VUDS) with SFN in patients with CPP.

Phosphorylation of Extracellular Proteins in in Sessile Mode of Growth.

is a problematic nosocomial pathogen owing to its increasing resistance to antibiotics and its great ability to survive in the hospital environment, which is linked to its capacity to form biofilms. Structural and functional investigations of post-translational modifications, such as phosphorylations, may lead to identification of candidates for therapeutic targets against this pathogen. Here, we present the first S/T/Y phosphosecretome of two strains, the reference strain ATCC 17978 and the virulent multi-drug resistant strain AB0057, cultured in two modes of growth (planktonic and biofilm) using TiO chromatography followed by high resolution mass spectrometry.

Robotic assisted proximal dorsal urethral diverticulectomy.

Introduction And Hypothesis: Urethral diverticula are rare but clinically significant entities among female patients. Ventrally located, mid-to distal, simple or horseshoe diverticula are most commonly observed and are usually repaired via a transvaginal approach with varying levels of difficulty but high success rates. Dorsally (anteriorly) located urethral diverticula are more challenging to repair secondary to the need to access the side of the urethra opposite the vaginal lumen, abutting the external urethral sphincter.
