CD320 expression is increased in breast cancer stem cells but does not promote their expansion or alter key histone methylation marks.

Carney C, Jenkins L, Jewell C et al. · 2025 · microPublication biology

Several lines of evidence suggest a potential link between stemness and vitamin B12, which contributes to S-adenosylmethionine (SAM) generation and hence methylation-dependent epigenetic control. Here we found that the vitamin B12…

Craniofacial Characteristics of Thalassemia Major Patients

Sacide Karakas, Ayfer Metin Tellioglu, Mehmet Bilgin et al. · 2019 · Eurasian Journal of Medicine

Abstract Objective: Thalassemias major are the most common autosomal recessive disorders; they are characterized by anomalies in the synthesis of the beta chains of hemoglobin and are often associated with varying degrees of craniofacial anomalies. The purpose of this study was to evaluate the craniofacial dimensions of β-thalassemia patients and to identify differences by comparing them to those of a control group. Materials and Methods: The study comprised 43 thalassemia major patients and 26 age- and sex- matched healthy control subjects. Anthropometric measurements were performed in six di

Long bone cross-sectional geometric properties of Later Stone Age foragers and herder–foragers

Michelle E. Cameron, Susan Pfeiffer · 2014 · South African Journal of Science

Diaphyseal cross-sectional geometry can be used to infer activity patterns in archaeological populations. We examined the cross-sectional geometric (CSG) properties of adult Later Stone Age (LSA) herder–forager long bones from the inland lower Orange River Valley of South Africa (n=5 m, 13 f). We then compared their CSG properties to LSA forager adults from the coastal fynbos (n=23 m, 14 f) and forest (n=17 m, 19 f) regions, building on a previous report (Stock and Pfeiffer, 2004). The periosteal mould method was used to quantify total subperiosteal area, torsional strength, bilateral asymmetr

Is pomegranate peels infusion effective for disinfection of toothbrushes?

Priscila Lima de Luna FREIRE, Priscila Hernández CAMPOS, Fabíola Galbiatti CARVALHO et al. · Revista de Odontologia da UNESP

Abstract Introduction Methods of decontamination or sanitization of toothbrushes have been questioned. Objective This study assessed the effectiveness of pomegranate peels infusion as a disinfectant of toothbrushes against Streptococcus mutans. Material and method A sample of 16 schoolchildren aged between 7 and 9 years performed brushing 5 days/week, with a careful brushing once a day. After each day of brushing, the toothbrushes were washed and sprayed with one disinfectant solution. This procedure was repeated for 4 weeks using one of the different solutions per week: distilled water (G1; n

Predictive Power of ESG Factors for DAX ESG 50 Index Forecasting Using Multivariate LSTM

Manuel Rosinus, Jan Lansky · 2025 · International Journal of Financial Studies

As investors increasingly use Environmental, Social, and Governance (ESG) criteria, a key challenge remains: ESG data is typically reported annually, while financial markets move much faster. This study investigates whether incorporating annual ESG scores can improve monthly stock return forecasts for German DAX-listed firms. We employ a multivariate long short-term memory (LSTM) network, a machine learning model ideal for time series data, to test this hypothesis over two periods: an 8-year analysis with a full set of ESG scores and a 16-year analysis with a single disclosure score. The evalu

Evaluating the effectiveness of advanced platelet-rich fibrin, photobiomodulation, pentoxifylline, and Alveogyl in the treatment of alveolar osteitis: a randomized controlled clinical trial

Alper Yuzbasioglu, Cennet Neslihan Eroglu · 2024 · BMC Oral Health

Abstract Background Alveolar osteitis is a type of small-scale osteomyelitis of the alveolar bone that occurs after tooth extraction, the etiology of which remains unknown, and alternative methods are being investigated for its treatment. The aim of this study was to compare the effectiveness of advanced platelet-rich fibrin (A-PRF), photobiomodulation (PBM), and Alveogyl (butamben, idoform, eugenol), which have shown success in the treatment of alveolar osteitis, with that of pentoxifylline (PTX) to determine whether PTX could be an alternative treatment for alveolar osteitis. Methods This st

Effect of methylprednisolone treatment on COVID-19: An inverse probability of treatment weighting analysis.

Lorenzo Porta, Sih-Shiang Huang, Chen Wei et al. · 2022 · PLoS ONE

Objectives While corticosteroids have been hypothesized to exert protective benefits in patients infected with SARS-CoV-2, data remain mixed. This study sought to investigate the outcomes of methylprednisone administration in an Italian cohort of hospitalized patients with confirmed SARS-CoV-2 infection. Methods Patients with confirmatory testing for SARS-CoV-2 were retrospectively enrolled from a tertiary university hospital in Milan, Italy from March 1st to April 30th, 2020 and divided into two groups by administration of corticosteroids. Methylprednisolone was administered to patients not r
