Human oral mucosa epithelial stem cells (hOMESCs) were obtained from a fresh oral biopsy collected from a healthy subject at the Fondazione Banca degli Occhi del Veneto (FBOV). An integration-free reprogramming protocol was applied exploiting episomal plasmids transfected into cells using a Nucleofector device. Around day 20 post transfection, several human induced pluripotent stem cell (hiPSC) colonies were manually picked and expanded. One of these (UNIPDi001-A-hiPSCs) expressed undifferentiated state marker alkaline phosphatase along with a panel of pluripotency state markers and was able to differentiate into the derivatives of all the three germ layers...

PURPOSE OF REVIEW: The formation of a hierarchical vascular network is a complex process that requires precise temporal and spatial integration of several signaling pathways. Amongst those, Notch has emerged as a key regulator of multiple steps that expand from endothelial sprouting to arterial specification and remains relevant in the adult. This review aims to summarize major concepts and rising hypotheses on the role of Notch signaling in the endothelium. RECENT FINDINGS: A wealth of new information has helped to clarify how Notch signaling cooperates with other pathways to orchestrate vascular morphogenesis, branching, and function...

Tumour lysis syndrome (TLS) is a rare oncological emergency in solid tumours. Because it is associated with bad short-term prognosis, early recognition and treatment are mandatory. This case refers to a middle-aged woman who presented with stage IV colon cancer, with massive hepatic involvement. After three cycles of first-line FOLFOX (folinic acid, 5-fluorouracil and oxaliplatin), she developed acute kidney injury and hyperkalaemia that did not respond to standard measures. High suspicion of TLS prompted further corroborating investigations and early intensive care unit admission...

Oocytes from prepubertal animals have a reduced ability to undergo embryo development and produce viable offspring. The present work used an ovine model consisting of oocytes derived from adult and prepubertal donors to assess the molecular status of oocytes and preimplantation embryos with different developmental competence. The lower potential of oocytes of young donors was confirmed in terms of in vitro developmental capabilities and kinetics. A panel of genes including maternal effect (DPPA3, GDF9, NMP2, ZAR1) and housekeeping genes (ACTB, RPL19, SDHA, YWHAZ, ATP1A1), genes involved in DNA methylation (DNMT1, DNMT3A, DNMT3B), genomic imprinting (IGF2R), pluripotency (NANOG, POU5F1) and cell cycle regulation (CCNB1, CDK1, MELK) was relatively quantified...

BACKGROUND: Psoriatic arthritis is a chronic inflammatory arthropathy that affects 14%-30% of patients with skin and/or nail psoriasis and leading to severe physical limitations and disability. It has been included in the group of spondyloarthropathy with which it shares clinical, radiologic, and serologic features in addition to familial and genetic relationship. Beyond skin and joint involvement, psoriatic arthritis is characterized by a high prevalence of extra-articular manifestation and comorbidities, such as autoimmune, infectious and neoplastic diseases...

Local businesses that offer foods may create different 'grazing environments' (characterized by sources of ready-to-consume foods) and 'grocery environments' (characterized by source of foods for later preparation). Such environments may be relevant to different populations at different times and may vary by neighborhood. In neighborhoods within two demographically distinct areas of the Bronx, NY [Area A (higher-poverty, greater minority representation, lesser vehicle ownership) vs. Area B], researchers assessed all storefront businesses for food offerings...

For monitoring minimal residual disease (MRD) in chronic myeloid leukemia (CML) the most recommended method is quantitative RT-PCR (RT-qPCR) for measuring BCR-ABL1 transcripts. Several studies reported that a DNA-based assay enhances the sensitivity of detection of the BCR-ABL1 genomic rearrangement, even if its characterization results difficult. We developed a DNA-based method for detecting and quantifying residual BCR-ABL1 positive leukemic stem cells in CML patients. We propose two alternative approaches: the first one is a fluorescence in situ hybridization (FISH)-based step followed by Sanger sequencing; the second one employs MinION, a single molecule sequencer based on nanopore technology...

The potential impact of routine real-time PCR testing of respiratory specimens from patients with presumptive tuberculosis in terms of diagnostic accuracy and time to tuberculosis treatment inception in low-prevalence settings remains largely unexplored. We conducted a prospective intervention cohort study. Respiratory specimens from 1,020 patients were examined by acid-fast bacilli smear microscopy, tested by the real-time Mycobacterium tuberculosis complex PCR assay (Abbott RealTi me MTB PCR) and cultured in mycobacterial media...

Leptospira inadai is classified as a species of the Leptospira intermediate group that has been poorly studied due to its apparent insignificance to human and animal health. Nevertheless, over the last two decades the species has been described in human cases in India and in carrier animals in Ecuador. Here, we present the first identification and genomic characterisation of L. inadai serogroup Lyme isolated from captured rodent in Brazil. Even though the M34/99 strain was not pathogenic for hamsters, it was able to establish renal colonisation...

Idiopathic intracranial hypertension (IIH) is associated with obesity, and weight loss is important to reduce intracranial pressure and improve visual function. A 38-year-old woman with IIH followed an extreme diet, which resulted in 30% weight loss (BMI moved from 34.9 to 24.6). Weight loss resulted in a significant reduction of papilloedema, normalization of intracranial pressure and improvement in headache pattern, but also induced a state of initial malnutrition, relevant depression and disability. She was discharged with the indication to start a controlled diet and improve physical activity: clinical situation get back to stability, with the patient loosing further weight (BMI=21...

We demonstrate that Surface-Anchored Metal-Organic Frameworks (SURMOFs) are extraordinary well-suited as resists for high-resolution Focused Electron Beam Induced Processing (FEBIP) techniques. The combination of such powerful lithographic protocols with the huge versatility of MOF materials are investigated in respect to their potential in nanostructures fabrication. The applied FEBIP methods rely on the local decomposition of Fe(CO)5 and Co(CO)3 NO as precursors, either by the direct impact of the focused electron beam (Electron Beam Induced Deposition, EBID) or through the interaction of the precursor molecules with preirradiated/activated SURMOF areas (Electron Beam Induced Surface Activation, EBISA)...

This paper extends the study of the induced temperature change in the mesostructure and in the physical properties occurring in aqueous mixtures of the ionic liquid 1-ethyl-3-methyl imidazolium octyl-sulfate [EMIm][OSO4 ]. For some compositions, these mixtures undergo a phase transition between the liquid (isotropic in the mesoscale) and the mesomorphic state (lyotropic liquid crystalline) at about room temperature. The behavior of mixtures doped with a divalent metal sulfate was investigated in order to observe their applicability as electrolytes...

SCOPE: Angiopoietin-like protein 4 (ANGPTL-4) regulates plasma lipoprotein levels but its relevance in human obesity and type 2 diabetes is largely unknown. We aimed to investigate the regulation of circulating ANGPTL-4 levels in obesity, type 2 diabetes and after changes in body weight. METHODS AND RESULTS: Circulating ANGPTL-4 levels were measured in two different cohorts. First, in a cross-sectional study, we evaluated ANGPTL-4 levels in lean and obese patients with normoglycemia or with altered glucose tolerance (n = 282)...

The Sexual Inhibition and Sexual Excitation Scales (SIS/SES) were developed to assess individual propensities for sexual excitation and sexual inhibition in men and women. The objective of the present study was to validate the Portuguese version of the SIS/SES and to investigate the degree to which SIS/SES scores predict different dimensions of Portuguese men's and women's sexual functioning. Gender differences were also examined. A community sample of 370 Portuguese men and 373 women completed self-report measures of sexual function (IIEF, Rosen et al...

BACKGROUND: Infants with a body weight of less than 10 kg are often not considered to be suitable candidates for renal transplantation (RTx). The objective of this study was to evaluate this arbitrary weight threshold for pediatric RTx. METHODS: We conducted a multicenter, retrospective, match-controlled cohort study on infants weighing less than 10 kg at time of engrafting (low-weight group [LWG], n = 38) compared to a matched control group (n = 76) with a body weight of 10-15 kg, using data from the first 2 years post-transplant derived from the CERTAIN Registry...

Segmental isotopic labeling can facilitate NMR studies of large proteins, multi-domain proteins, and proteins with repetitive sequences by alleviating NMR signal overlaps. Segmental isotopic labeling also allows us to investigate an individual domain in the context of a full-length protein by NMR. Several established methods are available for segmental isotopic labeling such as intein-mediated ligation, but each has specific requirements and limitations. Here, we report an enzymatic approach using bacterially produced asparagine endopeptidase from Oldenlandia affinis for segmental isotopic labeling of a protein with repetitive sequences, a designed armadillo repeat protein, by overcoming some of the shortcomings of enzymatic ligation for segmental isotopic labeling...
