Cytochrome aa3 is the terminal respiratory enzyme of all eukaryotes and many bacteria and archaea, reducing O2 to water and harnessing the free energy from the reaction to generate the transmembrane electrochemical potential. The diffusion of O2 to the heme-copper catalytic site, which is buried deep inside the enzyme, is the initiation step of the reaction chemistry. Our previous molecular dynamics (MD) study with cytochrome ba3 , a homologous enzyme of cytochrome aa3 in Thermus thermophilus, demonstrated that O2 diffuses from the lipid bilayer to its reduction site through a 25-Å long tunnel inferred by Xe-binding sites detected by X-ray crystallography$ ...

Breast cancer (BC) is a heterogeneous disease characterised by variant biology, metabolic activity and patient outcome. This study aimed to evaluate the biological and prognostic value of the membrane solute carrier, SLC3A2 in BC with emphasis on the intrinsic molecular subtypes. SLC3A2 was assessed at the genomic level, using METABRIC data (n = 1980), and at the proteomic level, using immunohistochemistry on tissue microarray (TMA) sections constructed from a large well-characterised primary BC cohort (n = 2500)...

Many plant-pathogenic fungi are highly host-specific. In most cases, host-specific interactions evolved at the time of speciation of the respective host plants. However, host jumps have occurred quite frequently, and still today the greatest threat for the emergence of new fungal diseases is the acquisition of infection capability of a new host by an existing plant pathogen. Understanding the mechanisms underlying host-switching events requires knowledge of the factors determining host-specificity. In this review, we highlight molecular methods that use a comparative approach for the identification of host-specificity factors...

Background: Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation tool suited to alter cortical excitability and activity via the application of weak direct electrical currents. An increasing number of studies in the addiction literature suggests that tDCS modulates subjective self-reported craving through stimulation of dorsolateral prefrontal cortex (DLPFC). The major goal of this study was to explore effects of bilateral DLPFC stimulation on resting state networks (RSNs) in association with drug craving modulation...

QUESTION 1: Is bilateral subthalamic nucleus deep brain stimulation (STN DBS) more, less, or as effective as bilateral globus pallidus internus deep brain stimulation (GPi DBS) in treating motor symptoms of Parkinson's disease, as measured by improvements in Unified Parkinson's Disease Rating Scale, part III (UPDRS-III) scores? RECOMMENDATION: Given that bilateral STN DBS is at least as effective as bilateral GPi DBS in treating motor symptoms of Parkinson's disease (as measured by improvements in UPDRS-III scores), consideration can be given to the selection of either target in patients undergoing surgery to treat motor symptoms...

BACKGROUND:  Bleeding risk scores have shown a limited predictive ability in elderly patients with acute coronary syndromes (ACS). No study explored the role of a comprehensive geriatric assessment to predict in-hospital bleeding in this clinical setting. METHODS:  The prospective multicentre LONGEVO-SCA registry included 532 unselected patients with non-ST segment elevation ACS (NSTEACS) aged 80 years or older. Comorbidity (Charlson index), frailty (FRAIL scale), disability (Barthel index and Lawton-Brody index), cognitive status (Pfeiffer test) and nutritional risk (mini nutritional assessment-short form test) were assessed during hospitalization...

BACKGROUND: The vascular closure staple clips have been studied in animal models and shown to have comparable results with sutured repair when it comes to the healing process, degree of vessel narrowing, and risk of thrombosis. However, they are clearly superior when the speed of application is taken into account, and they were clinically used in many vascular repair processes. Nevertheless, their usefulness in intracranial vascular surgery has not been described. OBJECTIVE: To describe the usefulness of hemoclips in fast and efficient repair of medium-sized and large intracranial vessels...

INTRODUCTION AND OBJECTIVES: Although clinical guidelines recommend invasive management in non-ST-segment elevation myocardial infarction (NSTEMI), this strategy is underused in frail elderly patients in the real world. Furthermore, these patients are underrepresented in clinical trials and therefore the evidence is scarce. Our hypothesis is that an invasive strategy will improve prognosis in elderly frail patients with NSTEMI. METHODS: This will be a prospective, multicenter, randomized trial, in which the conservative and invasive strategies will be compared in patients meeting all of the following inclusion criteria: NSTEMI diagnosis, age ≥ 70 years, and frailty defined by a category ≥ 4 in the Clinical Frailty Scale...

INTRODUCTION: Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. CASE PRESENTATION: We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy...

INTRODUCTION: Tuberculosis (TB) remains a huge worldwide burden, despite extensive vaccination coverage with the Bacillus Calmette-Guérin (BCG), the only vaccine available against this disease, indicating that BCG-driven immunity is inadequate to protect the human population against TB. This underscore the critical necessitate to develop an improved TB vaccine, based on a better understanding of host-pathogen interactions and immune responses during mycobacterial infection. AIM OF THE WORK: To examine whether the exogenous addition of IFN-β could improve dendritic cell (DC) response to Mycobacterium bovis (M...

OBJECTIVES: Cholecystectomy is the definitive management of gallstone pancreatitis (GSP). The benefit of endoscopic retrograde cholangiopancreatography (ERCP) in patients who do not undergo cholecystectomy remains unclear. This study aims to evaluate the effect of ERCP on all-cause and pancreatitis readmissions in GSP. METHODS: Adult hospitalizations for GSP in the 2010-2014 National Readmissions Database were divided into the following 3 groups: (1) no cholecystectomy nor ERCP, (2) no cholecystectomy with ERCP, and (3) cholecystectomy group...

A 25-year-old obese woman experienced ischemic renal injury as a complication of intragastric balloon (IGB) insertion for weight reduction. Although IGB is associated with a low risk of renal injury in the form of acute renal failure, this presentation has never been reported. The patient responded well to treatment, with complete clinical and radiologic resolution after balloon removal. She did not have an apparent cause of renal ischemia other than a significant compression of the renal vessels by the balloon as seen on imaging...

CHIP/STUB1 ubiquitin ligase is a negative co-chaperone for HSP90/HSC70, and its expression is reduced or lost in several cancers, including breast cancer. Using an extensive and well-annotated breast cancer tissue collection, we identified the loss of nuclear but not cytoplasmic CHIP to predict more aggressive tumorigenesis and shorter patient survival, with loss of CHIP in two-thirds of ErbB2+ and triple-negative breast cancers and in one-third of ER+ breast cancers. Reduced CHIP expression was seen in breast cancer patient-derived xenograft tumors and in ErbB2+ and triple-negative breast cancer cell lines...

BACKGROUND AND STUDY AIMS: Endoscopic ultrasound elastography (EUS-elastography), or sono-elastography, has emerged in the past 2 decades as a qualitative method of estimating tissue stiffness. Strain elastography allows for semi-quantitative measurements of the average elasticity of a lesion, and previous studies have proposed the strain ratio (SR) for overcoming the limitations of the elasticity score. The main objective of this study is to assess the specificity, sensitivity and predictive values of the SR measured by EUS-elastography in differentiating benign from malignant lymph nodes (LNs)...

BACKGROUND: Despite enormous progresses in understanding pathophysiology of the lower urinary tract, antimuscarinics remain the chief clinically well-established approach for improving symptoms of overactive bladder (OAB). Dry mouth on the other hand remains one of the most untolerated systemic side effects of these drugs that limits their uses and results in high discontinuation rate. Three novel drugs have been recently approved by US Food and Drug Administration for treatment of OAB: trospium, darifenacin, and solifenacin...
