In theory, human diseases in which a specific cell type degenerates, such as neurodegenerative diseases, can be therapeutically addressed by replacement of the lost cells. The classical strategy for cell replacement is exogenous cell transplantation, but now, cell replacement can also be achieved with in situ reprogramming. Indeed, many of these disorders are age-dependent, and "rejuvenating" strategies based on cell epigenetic modifications are a possible approach to counteract disease progression. In this context, transient and/or partial reprogramming of adult somatic cells towards pluripotency can be a promising tool for neuroregeneration...

Since its discovery as a genetic risk factor for Alzheimer's disease, the APOE4 allele has been linked to the majority of the pathological findings associated with the disease progression. These include abnormalities of the endocytic, autophagic, and lysosomal machineries, which begin at the most early stages of Alzheimer's disease development. Considering that these three vesicular systems share common features and, in fact, comprise an interconnected cargo-trafficking and degradation network, some of the effects of APOE4 are interrelated, while others are system-specific...

Experimental studies reported that osteopontin (OPN), a matricellular protein, is induced in brain after subarachnoid hemorrhage (SAH). The aim of this study was to investigate the relationships between plasma OPN levels and outcome after aneurysmal SAH in a clinical setting. This is a prospective study consisting of 109 aneurysmal SAH patients who underwent aneurysmal obliteration within 48 h of SAH. Plasma OPN concentrations were serially determined at days 1-3, 4-6, 7-9, and 10-12 after onset. Various clinical factors as well as OPN values were compared between patients with 90-day good and poor outcomes...

BACKGROUND: pN stage and breast cancer subtypes (BCS) are both well-recognized prognostic indicators. Our previous work has highlighted that patients even with the same pN stage exhibited a significant survival difference in different BCS. Given this achievement, we hypothesized that a statistical interaction might exist between pN stage and BCS. The aim of this retrospective cohort study was to compare the prognostic value of the combined pN stage and BCS (pNnew stage) with either pN stage or BCS alone, and to determine if this combined new stage could serve as an alternative discriminator of outcome...

In searching for clinical biomarkers of the somatosensory function, we studied reproducibility of somatosensory potentials (SEP) evoked by finger stimulation in healthy subjects. SEPs induced by electrical stimulation and especially after median nerve stimulation is a method widely used in the literature. It is unclear, however, if the EEG recordings after finger stimulation are reproducible within the same subject. We tested in five healthy subjects the consistency and reproducibility of responses through bootstrapping as well as test-retest recordings...

Postoperative delirium (POD) is an adverse clinical outcome characterized by cognitive, affective and behavioral symptoms with typically an acute onset and a fluctuating course. POD is attributed to certain patients' predisposing factors as well as to treatment-related precipitating factors. While there are several single-component interventions for the prevention of POD, evolving evidence suggests the importance of a system approach in the prevention of POD. This involves strategies by multidisciplinary teams with additional geriatric consultation services to identify risk factors for POD and to modify their impact on the perioperative course...

Advances in proteomics have fueled the search for novel cancer biomarkers with higher selectivity. Differential expression of low abundant proteins has been the usual way of finding those biomarkers. The existence of a selective receptor for each biomarker is compulsory for their use in diagnostic/prognostic assays. Antibodies are the receptors of choice in most cases although aptamers are becoming familiar because of their facile and reproducible synthesis, chemical stability as well as comparable affinity and selectivity...

The aim of the present study was to determine some properties of antibiotic-resistant bacterial strains isolated from onsite wastewater technology in relation to biofilm formation, e.g., autoaggregation and motility. Additionally, biosurfactant production by the isolates was also evaluated. The ability of selected strains to develop a biofilm was assessed by using the crystal violet method, which allows to indirectly quantify the attached bacterial biomass (live, dead cells, and polysaccharides as well). Obtained results showed that 19 of the analyzed strains were able to produce biofilm after 72 h of incubation...

Transformation from q to Q during wheat domestication functioned outside the boundary of threshability to increase yield, grains m-2, grain weight and roundness, but to reduce grains per spike/spikelet. Mutation of the Q gene, well-known affecting wheat spike structure, represents a key domestication step in the formation of today's free-threshing, economically important wheats. In a previous study, multiple yield components and spike characteristics were associated with the Q gene interval in the bread wheat 'Forno' × European spelt 'Oberkulmer' recombinant inbred line population...

INTRODUCTION: Vascular compression is the main pathogenetic factor in apparently primary trigeminal neuralgia; however some patients may present with clinically classical neuralgia but no vascular conflict on MRI or even at surgery. Several factors have been cited as alternative or supplementary factors that may cause neuralgia. This work focuses on the shape of the petrous ridge at the point of exit from the cavum trigeminus as well as the angulation of the nerve at this point. METHODS: Patients with trigeminal neuralgia that had performed a complete imagery workup according to our protocol and had microvascular decompression were included as well as ten controls...

Aim of the study was the definition of a predictive model for the initial diagnosis of thrombotic microangiopathies (TMA). We retrospectively collected data on all adult patients admitted to the Gemelli Hospital from 2010 to 2014. ICD-9 codes from primary diagnoses were used for TMA diagnosis. Demographic and laboratory characteristics on admission of patients with TMA were then compared with a random sample of 500 patients with other diagnoses. The prediction model was externally validated in a cohort from another hospital...

Researchers have consistently advocated positive associations between religion and well-being. The present research takes a step forward and explores potential mechanisms behind the same. The mediating role of a surprisingly neglected mechanism, positive virtues, specifically gratitude, forgiveness and altruism, is studied through a quantitative study on a sample of 220 adult respondents residing in Delhi NCR. The participants adhered to one of the six major religions present in India. Mediational analysis revealed that gratitude mediated the relationship between religiosity, spirituality and well-being via two pathways of forgiveness and altruism...

Experiences of transcendence can promote growth, creativity and altruism, but often exist in tension with critical thought and can feature problematically in certain mental disorders. Identification of the core elements in the experience of transcendence-suspending disbelief, being moved or inspired, surrendering oneself and identifying within a larger context, can clarify its relationship to psychopathology, and the basis for a clinician's role. To help individuals engage transcendent resources well, clinicians can help patients recognize how depression and trauma may interfere with engagement, masochistic and magical tendencies may distort healthy self-surrender, and vulnerability to social pressure may interfere with mature identification with a larger context or community...

Daclatasvir is a first-in-class, highly selective, hepatitis C virus, non-structural protein 5a polymerase replication complex inhibitor with picomolar potency and broad genotypic coverage in vitro. Daclatasvir undergoes rapid absorption, with a time to reach maximum plasma concentration of 1-2 h and an elimination half-life of ~ 10 to 14 h observed in single-ascending dose studies. Steady state was achieved by day 4 in multiple-ascending dose studies. Daclatasvir can be administered without regard to food or pH modifiers...

Multi-site brain MRI analysis is needed in big data neuroimaging studies, but challenging. The challenges lie in almost every analysis step including skull stripping. The diversities in multi-site brain MR images make it difficult to tune parameters specific to subjects or imaging protocols. Alternatively, using constant parameter settings often leads to inaccurate, inconsistent and even failed skull stripping results. One reason is that images scanned at different sites, under different scanners or protocols, and/or by different technicians often have very different fields of view (FOVs)...

BACKGROUND: Patients with metastatic or recurrent esophageal squamous cell carcinoma (ESCC) have a poor prognosis. For decades, the most widely used first-line chemotherapy regimen for these patients has been the combination of 5-fluorouracil + cisplatin (CF). However, prognostic factors of CF as first-line chemotherapy for ESCC have not been clarified. METHODS: A total of 187 patients with metastatic or recurrent esophageal ESCC treated with CF at the National Cancer Center Hospital between January 2001 and December 2012 were enrolled in the study...

Monitoring of microalgae in water supplies and industrial applications are becoming increasingly important, yet there are few options available that are simple and accurate, and can provide real-time information. The present work illustrates a new method to determine the concentration of microalgae in water and wastewater using spectrophotometry and the first derivative of absorbance. Chlorella vulgaris was used as an indicator microalga, spiked in water samples representing a range of water qualities (distilled water, surface water, and wastewater), and correlations among C...

INTRODUCTION: Successful treatment of periprosthetic shoulder fractures depends on the right strategy, starting with a well-structured classification of the fracture. Unfortunately, clinically relevant factors for treatment planning are missing in the pre-existing classifications. Therefore, the aim of the present study was to describe a new specific classification system for periprosthetic shoulder fractures including a structured treatment algorithm for this important fragility fracture issue...
