Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC
Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
The tale of TILs in breast cancer : a report from the International Immuno-Oncology Biomarker Working Group
The advent of immune-checkpoint inhibitors (ICI) in modern oncology has significantly improved survival in several cancer settings.
A subgroup of women with breast cancer (BC) has immunogenic infiltration of lymphocytes with expression of programmed deathligand
1 (PD-L1). These patients may potentially benefit from ICI targeting the programmed death 1 (PD-1)/PD-L1 signaling axis. The
use of tumor-infiltrating lymphocytes (TILs) as predictive and prognostic biomarkers has been under intense examination. Emerging
data suggest that TILs are associated with response to both cytotoxic treatments and immunotherapy, particularly for patients with
triple-negative BC. In this review from The International Immuno-Oncology Biomarker Working Group, we discuss (a) the biological
understanding of TILs, (b) their analytical and clinical validity and efforts toward the clinical utility in BC, and (c) the current status of
PD-L1 and TIL testing across different continents, including experiences from low-to-middle-income countries, incorporating also
the view of a patient advocate. This information will help set the stage for future approaches to optimize the understanding and
clinical utilization of TIL analysis in patients with BC.The National Health and Medical Research Council of Australia; the Cure; the Royal Australasian College of Physicians; the NIH/NCI ; the National Breast Cancer Foundation of Australia Endowed Chair; the Breast Cancer Research Foundation, New York and the Breast Cancer Research Foundation (BCRF).www.nature.com/npjbcanceram2022Immunolog
Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
All-arthroscopic AMIC® (AT-AMIC) for the treatment of talar osteochondral defects
Category: Arthroscopy Introduction/Purpose: Various operative procedures have been used to treat osteochondral lesions of the talus. Among the new alternatives to treat these lesions, Autologous Matrix-Induced Chondrogenesis (AMIC®) has proven to provide satisfactory results through medium-term follow-up. The aim of this study is to report early post-operative clinical results of patients submitted to the AT-AMIC® technique and autologous bone graft, when necessary, for OLT’s at a six-month minimum follow-up. Methods: This is case series of 17 consecutive patients that were submitted to AT-AMIC®, between january of 2016 and april of 2017. 9 men and 8 women, between 15 and 67 years were diagnosed with OLTs with the typical history of deep ankle pain and corresponding magnetic resonance imaging injury. Surgery was proposed only after failure of conservative treatment of at least 3 months. Surgeries were performed by three different surgeons, with high arthroscopic experience. Patients answered the AOFAS score preoperatively and at the last follow-up, ranging from 6 to 18 months Results: Average size of OLTs were 1,12 cm2, with Raikin 4 location being the most common (70,5%). Calcaneal osteotomy was the most common associated procedure, with 17,6%. Average follow-up was 10,76 months. Average AOFAS before surgery was 46,35, increasing to 89,53 at the last follow-up. This difference was statistically significant with a p-value of <0,001. No complications were observed and no changes in the post-operative protocol were needed. Conclusion: AT-AMIC® is a reliable and reproducible method of treatment for OLTs, reaching high clinical postoperative scores, with a very low rate of complications. Further comparative study is needed to prove its efficacy
Prevalence of Depressive Symptoms in Patients Requesting Cosmetic Breast Surgery in Midwestern Brazil
Background:. The prevalence of depressive symptoms (DS) before cosmetic breast surgery was analyzed in the public (PbI) and private (PrI) institutions, comparing types of surgery and patients’ sociodemographic characteristics.
Methods:. A cross-sectional, observational, analytical study to evaluate the prevalence of DS in 185 patients of 18–71 years of age requesting 4 different cosmetic breast surgeries (with and without implants) at public and private institutions. Patients were assessed using the Beck Depression Inventory and analyzed for statistical comparison.
Results:. The most common surgical procedures were reduction mammoplasty in the PbI and augmentation mammoplasty in the PrI. The prevalence of the positive risk for depressive disorder (≥15 points in Beck Depression Inventory) in the PbI was 25.8%, whereas in the PrI: 11.4% (P = 0.012). Moderate and severe DS were, respectively, 120% and 242% higher in the PbI than in the PrI. No patients requesting mastopexy without implants had DS. The highest prevalence (51.4%) of DS occurred in patients with breast implants indications (augmentation mammoplasty and mastopexy with implants). The presence (P = 0.12) or absence (P = 0.33) of implant did not demonstrate a higher risk of DS. Among all patients, 7% answered positively to the statements on suicide ideation, with predominance within the group of implants (54.5%). There were significant differences between the PbI and PrI.
Conclusions:. The prevalence of DS was high (18.9%), with the risk being 2.3 times greater in the PbI. Patients from PbI and PrI showed significant different profiles. Patients for breast implants showed a higher score for suicide ideation
