Immediate implant placement in damaged extraction sockets: a systematic review and meta-analysis of randomized controlled trials.

Objectives: The aim of this study was to observe whether immediate implant placement (IIP) into damaged extraction sockets is a successful modality for treating hopeless teeth that require extraction.

Data Source: An electronic search was carried out through four databases (PubMed/MEDLINE, Web of Science, Scopus, and ScienceDirect) to identify randomized controlled trials (2013-2023) to understand whether IIP in damaged sockets is a successful treatment. The focus question was, 'In a patient with a hopeless tooth that needs extraction with the indication for dental implant treatment, is IIP in damaged extraction sockets, compared to undamaged sockets or healed sites, an effective method for the replacement of hopeless teeth and achieving a favorable clinical result?' The risk of bias was appraised and a meta-analysis using random effect was applied.

Vestibular Impairment and Postural Development in Children With Bilateral Profound Hearing Loss.

Importance: Children with profound hearing loss (HL) and vestibular impairment have worse cochlear implant outcomes compared with those without vestibular impairment. However, the decision for cochlear implantation is rarely based on vestibular function assessment as a complement to audiologic testing.

Objectives: To identify the prevalence of vestibular impairment according to HL origin and to assess the association between vestibular impairment and delayed posturomotor development in children with profound HL.

Cervical vestibular evoked myogenic potentials in healthy children: Normative values for bone and air conduction.

Objectives: To characterize cervical vestibular evoked myogenic potentials (c-VEMPs) in bone conduction (BC) and air conduction (AC) in healthy children, to compare the responses to adults and to provide normative values according to age and sex.

Design: Observational study in a large cohort of healthy children ( = 118) and adults ( = 41). The c-VEMPs were normalized with the individual EMG traces, the amplitude ratios were modeled with the Royston-Wright method.

Ataxic speech disorders and Parkinson's disease diagnostics via stochastic embedding of empirical mode decomposition.

Medical diagnostic methods that utilise modalities of patient symptoms such as speech are increasingly being used for initial diagnostic purposes and monitoring disease state progression. Speech disorders are particularly prevalent in neurological degenerative diseases such as Parkinson's disease, the focus of the study undertaken in this work. We will demonstrate state-of-the-art statistical time-series methods that combine elements of statistical time series modelling and signal processing with modern machine learning methods based on Gaussian process models to develop methods to accurately detect a core symptom of speech disorder in individuals who have Parkinson's disease.

Chemical Profile and Biological Potential of Hornodermoporus martius (Agaricomycetes) from Paraguay.

To further knowledge of the biological activity of native neotropical fungal species, this study aimed to determine the chemical composition and microbiological activity of Hornodermoporus martius. Ethanol, hexane, diethyl ether, and ethyl acetate fractions and the water residue were analyzed and resulted in a total phenolic compound content between 13 and 63 mg of gallic acid equivalents per gram of crude extract. The total antioxidants ranged between 3 and 19 mg of ascorbic acid equivalents per gram of crude extract, and the percentage of antioxidant activity was determined to be between 6 and 25%.

Crohn's Disease-Related Stoma Complications and Their Impact on Postsurgical Course.

Introduction: Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. The diversion through a colostomy or an ileostomy is sometimes required for disease control. In these patients, common stoma-related complications sum up with CD-related complications and often require revisional surgery.

Bioactive Compounds and Antioxidant Activity of Four Native Species of the Ganodermataceae Family (Agaricomycetes) from Paraguay.

The lack of information on the chemistry of higher fungi in Paraguay and the search for new sources of secondary metabolites motivated this chemical study of four wild species of the Ganodermataceae family and the comparison with a commercial species cultivated under laboratory conditions. Qualitative identification of secondary metabolites as well as a quantification of phenolic compounds content and antioxidant potential of ethanolic extracts was carried out of four wild species: Cristataspora flavipora, two specimens of different phylogenetic clades of Ganoderma australe (clade 1 and clade 2), G. martinicense, G.

More Favorable Short and Long-Term Outcomes for Screen-Detected Colorectal Cancer Patients.

Design: Population-based cross-sectional study.

Participants: A total of 584 consecutive patients admitted to a Rehabilitative Cardiology Unit.

Maize expressing the sunflower transcription factor HaHB11 has improved productivity in controlled and field conditions.

HaHB11 is a sunflower transcription factor from the homeodomain-leucine zipper I family. Transgenic Arabidopsis plants expressing HaHB11 had larger rosettes and improved seed yield. In this work maize plants from hybrid HiII were transformed with 35S:HaHB11, ZmUBI:HaHB11 and ProHaHB11:HaHB11 and then backcrossed to B73 to obtain a more homozygous inbred phenotype.

Participation of chromatin-remodeling proteins in the repair of ultraviolet-B-damaged DNA.

The genome of plants is organized into chromatin, affecting the rates of transcription, DNA recombination, and repair. In this work, we have investigated the consequences of reduced expression of some chromatin-remodeling factors and histone acetylation in maize (Zea mays) and Arabidopsis (Arabidopsis thaliana) in their participation in DNA repair after ultraviolet (UV)-B irradiation. Plants deficient in NFC102/NFC4 or SDG102/SDG26 showed more damaged DNA than wild-type plants; however, the Arabidopsis chc1 mutant showed similar accumulation of cyclobutane pyrimidine dimers as wild-type plants, in contrast to the increased DNA damage measured in the maize chc101 RNA interference line.

Transcriptomic, proteomic and metabolomic analysis of maize responses to UV-B: comparison of greenhouse and field growth conditions.

UV-B radiation from normal solar fluence elicits physiological and developmental changes in plants under fluctuating environmental conditions. Most UV photobiology studies in plants utilize controlled greenhouse and growth chamber environments in which few conditions vary except the brief presence of UV-B radiation. Our purpose was to compare responses to UV-B in irradiated and shielded maize organs in field (natural solar plus 2x solar supplementation for defined periods) and greenhouse (2x solar supplementation only) conditions during a 4 hour exposure.

Transcriptomic, proteomic and metabolomic analysis of UV-B signaling in maize.

Background: Under normal solar fluence, UV-B damages macromolecules, but it also elicits physiological acclimation and developmental changes in plants. Excess UV-B decreases crop yield. Using a treatment twice solar fluence, we focus on discovering signals produced in UV-B-irradiated maize leaves that translate to systemic changes in shielded leaves and immature ears.

Proctocolectomy for ulcerative colitis after liver transplantation for primary sclerosing cholangitis.

Background: Sclerosing cholangitis is a chronic cholestatic liver disease of unknown etiology. Immunologic and genetic factors may be involved in the pathogenesis of the disease, characterized by fibrosis involving bile ducts, which can progress to biliary cirrhosis and cholangiocarcinoma (8%-30%). Sclerosing cholangitis is frequently associated with inflammatory bowel diseases, especially ulcerative colitis (60%-80%), which may require a proctocolectomy with ileal pouch anal anastomosis if there is no response to therapy or the appearance of colonic carcinoma.

Histone acetylation and chromatin remodeling are required for UV-B-dependent transcriptional activation of regulated genes in maize.

The nuclear proteomes of maize (Zea mays) lines that differ in UV-B tolerance were compared by two-dimensional gel electrophoresis after UV light treatment. Differential accumulation of chromatin proteins, particularly histones, constituted the largest class identified by mass spectrometry. UV-B-tolerant landraces and the B73 inbred line show twice as many protein changes as the UV-B-sensitive b, pl W23 inbred line and transgenic maize expressing RNA interference constructs directed against chromatin factors.
