Ana1/CEP295 is an essential player in the centrosome maintenance program regulated by Polo kinase and the PCM.

Centrioles are part of centrosomes and cilia, which are microtubule organising centres (MTOC) with diverse functions. Despite their stability, centrioles can disappear during differentiation, such as in oocytes, but little is known about the regulation of their structural integrity. Our previous research revealed that the pericentriolar material (PCM) that surrounds centrioles and its recruiter, Polo kinase, are downregulated in oogenesis and sufficient for maintaining both centrosome structural integrity and MTOC activity.

Comparison of Oral and IV 18 F-NaF PET/CT Administration in the Assessment of Bone Metastases in Patients With Breast or Prostate Cancers.

Purpose: The aim of this study was to compare oral and IV administrations of 18 F-NaF PET/CT for detection of suspicious bone metastatic lesions of breast and prostate cancers.

Patients And Methods: Thirty-six patients with breast (n = 23) or prostate (n = 13) cancers and high risk for bone metastases were prospectively evaluated. All patients underwent 2 PET/CT studies after IV and oral 18 F-NaF administration within a 2 to 23 days interval between them.

Consumer vulnerability and well-being across contexts: Implications for international businesses.

This article assesses the relationship between consumer vulnerability (CV) and well-being (WB) by comparing the effects of ordinary (non-pandemic) and pandemic consumption contexts among Portuguese and Brazilian consumers. Data on pre-and post-pandemic perceived vulnerability and well-being from a cross-cultural sample of 397 consumers were analyzed through structural equations modelling using the PLS-Path. The results revealed an inverse relationship between CV and well-being, which worsened with the emergence of the pandemic.

F-FDG-PET/CT-measured parameters as potential predictors of residual disease after neoadjuvant chemoradiotherapy in patients with esophageal carcinoma.

Objective: To evaluate the maximum and mean standardized uptake values, together with the metabolic tumor value and the total lesion glycolysis, at the primary tumor site, as determined by F-fluorodeoxyglucose positron-emission tomography/computed tomography (F-FDG-PET/CT), performed before and after neoadjuvant chemoradiotherapy (nCRT), as predictors of residual disease (RD) in patients with esophageal cancer.

Materials And Methods: The standardized uptake values and the volumetric parameters (metabolic tumor value and total lesion glycolysis) were determined by F-FDG-PET/CT to identify RD in 39 patients before and after nCRT for esophageal carcinoma. We used receiver operating characteristic curves to analyze the diagnostic performance of F-FDG-PET/CT parameters in the definition of RD.

COVID-19: the impact on oral health care.

The COVID-19 pandemic has highlighted the economic, social, and oral care health inequities in societies, especially in the developing world. Severe restrictions have been imposed on dental practices, limiting prophylactic and routine oral care health, allowing treatment only for emergencies. Since dental care includes procedures that generate aerosols, the risk of infection for dental personnel has increased significantly.

A taxonomic revision of the Bothynus villiersi Endrdi, 1968 species group (Coleoptera: Scarabaeidae: Dynastinae).

Methods: We prospectively evaluated, in a quaternary hospital, patients undergoing coronary angiography or percutaneous coronary intervention by transulnar approach, in case of failure or contraindication to the ipsilateral radial access.

Results: Between August 2018 and March 2020, of the 5,916 invasive coronary procedures performed, 2.

Whole Skeletal Mean SUV Measured on F-NaF PET/CT Studies as a Prognostic Indicator in Patients with Bone Metastatic Breast Cancer.

In this work we assessed the association between the whole skeletal mean standardized uptake value (SUV) measured on F-NaF PET/CT studies and the overall survival (OS) of bone metastatic breast cancer patients. We retrospectively analyzed 176 patients with breast cancer and bone metastatic disease who performed F-NaF PET/CT studies. The outcomes of the patients (dead or alive) were established based on the last information available on their files.

Carotenoid biosynthetic gene expression, pigment and n-3 fatty acid contents in carotenoid-rich Tetraselmis striata CTP4 strains under heat stress combined with high light.

In this study, two carotenoid-rich strains of the euryhaline microalga Tetraselmis striata CTP4 were isolated by random mutagenesis combined with selection via fluorescence activated cell sorting and growth on norflurazon. Both strains, ED5 and B11, showed an up to 1.5-fold increase in carotenoid contents as compared with the wildtype, independent of the growth conditions.

A hidden Megasoma/ Kirby species under the enigmatic genus Gibboryctes Endrödi (Coleoptera: Scarabaeidae: Dynastinae).

Gibboryctes Endrödi, 1974 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) is an uncommon Neotropical genus comprising five valid species (Gasca-Álvarez Ratcliffe 2011; Dupuis 2019). Endrödi (1974) established the genus based on Gibboryctes szelenyii Endrödi, 1974 and defined it by the absence of sexual dimorphism; short, triangular, and pointed clypeus; bidentate mandibles projected beyond the anterior clypeal margin; and protibiae quadridentate. After that, Gibboryctes waldenfelsi (Endrödi, 1977) and Gibboryctes gracilicornis (Prell, 1912) were assigned to Gibboryctes, from Strategus Kirby, 1828 and Heterogomphus Burmeister, 1847, respectively (Ratcliffe Dechambre 1983; Dupuis Dechambre 2008).

Plk4 triggers autonomous de novo centriole biogenesis and maturation.

Centrioles form centrosomes and cilia. In most proliferating cells, centrioles assemble through canonical duplication, which is spatially, temporally, and numerically regulated by the cell cycle and the presence of mature centrioles. However, in certain cell types, centrioles assemble de novo, yet by poorly understood mechanisms.

Prognostic value of 18F-fluorodeoxyglucose PET/computed tomography metabolic parameters measured in the primary tumor and suspicious lymph nodes before neoadjuvant therapy in patients with esophageal carcinoma.

Background: 18F-fluorodeoxyglucose PET/computed tomography (18F-FDG PET/CT) metabolic parameters are prognostic indicators in several neoplasms. This study aimed to evaluate the prognostic value of the maximum and average standardized uptake value (SUVmax and SUVavg), metabolic tumor value (MTV), and total lesion glycolysis (TLG) measured in the primary tumor and suspicious lymph nodes preneoadjuvant therapy in patients submitted to surgical resection for esophageal cancer.

Methods: A cohort of 113 patients with esophageal cancer who performed 18F-FDG PET/CT preneoadjuvant therapy was assessed.

Comparison of F-NaF PET/CT with Other Imaging Methods in the Detection of Bone Metastases in Patients with Medullary Thyroid Cancer: a Report of a Series of 31 Cases.
