The study's purpose was to assess whether individuals who developed a second malignant neoplasm (SMN) after treatment for a first malignant neoplasm (FMN) had a lower ability to repair DNA double-strand breaks (DSBs) using a bioassay with γH2AX intensity as a surrogate endpoint. In a case-control study nested in…

Ozone concentrations in Houston, Texas, are among the highest in the United States, posing significant risks to human health. This study aimed to evaluate the impact of various emissions sources and meteorological factors on ozone formation in Houston from 2017 to 2021 using a comprehensive PMF-SHAP approach. First, we…

This study examines mammography-enhancing intervention studies that focus on women in groups with historically lower rates of mammography use than the general population. These groups consist of women who are disproportionately older, poorer, of racial-ethnic minorities, have lower levels of formal education, and live…

BACKGROUND: French community pharmacists are facing an increasing demand to provide a wider range of services to meet the needs of the population. These new missions must be evaluated by primary care research studies. This study aims to explore the factors that influence French community pharmacists' willingness to par…

BACKGROUND: Limited qualitative research indicates that beggar children might be victims of forced labor, and/or modern slavery. However, research quantifying the manifestations and health-related implications of forced child begging is missing in the literature. Because forced child begging might be physically, mental…

INTRODUCTION: Systematic Review and Meta-Analysis (SRMAs) in neurosurgery have significantly increased. With approximately 1 million patients affected by cerebrovascular disease annually, interpreting SRMAs necessitates a systematic approach. The objective of this review is to identify and describe four essential…

Patients with end-stage kidney disease, particularly those treated with dialysis, develop proliferative processes in their native kidneys that result in the formation of multiple acquired renal cysts, renal adenomas, and carcinomas. Data about these abnormalities have been acquired mainly from retrospective studies. We…

Creativity is increasingly recognized as a core competency for the 21st century, making its development a priority in education, research, and industry. To effectively cultivate creativity, researchers and educators need reliable and accessible assessment tools. Recent software developments have significantly enhanced…

The classical models of investigating Shigella flexneri adherence and invasion of tissue culture cells involve either bacterial centrifugation (spinoculation) or the use of AfaE adhesin to overcome the low infection rate observed in vitro. However clinically, S. flexneri clearly adheres and invades the human…

AIMS: DOG1 and protein kinase C (PKC) theta are both sensitive immunohistochemical markers of gastrointestinal stromal tumour (GIST). However, there are conflicting data regarding the specificity of the most commonly used PKC theta antibody (clone 27), and there are no existing data regarding the specificity of the onl…

BACKGROUND: C-KIT is a receptor tyrosine kinase with oncogenic properties overexpressed in PCa cases. Through the use of an alternative promoter, a truncated c-KIT protein (tr-KIT) of 30-50 kDa is generated, lacking the extracellular and transmembrane domain. Tr-KIT promotes the formation of a multi-molecular complex c…

The study's aim was to investigate the S100A4-mediated mechanisms of the regulation of tumor cell proliferation and migration in the human triple-positive breast carcinoma cell line MCF-7 (TPBC) and triple-negative breast carcinoma cell line MDA-MB-231 (TNBC). The proliferative activity of TNBC more than doubled during…

OBJECTIVE: Cancer cells reportedly have the ability to escape from the immune system, mainly from natural killer (NK) cells. Although the real mechanisms are complicated, some inhibitors that are secreted from the cancer cells might play an important role. This study's aim was to investigate the potential mediator rele…

The replication checkpoint monitors the progress of DNA replication forks during S phase, and delays the firing of later replication origins when active replication forks are stalled due to collisions with damaged or abnormally structured DNA. Key components of the replication checkpoint pathway are the apical protein…

This study's objective was to investigate morphometric gender differences of the cerebral cortex in six males and five females, 12 to 24 years old. Though human brains lack sexual dimorphism on routine neuropathologic examinations, gender-specific brain weight, functional, and morphologic differences exist, suggesting…

BACKGROUND: Genetic association studies are conducted to discover genetic loci that contribute to an inherited trait, identify the variants behind these associations and ascertain their functional role in determining the phenotype. To date, functional annotations of the genetic variants have rarely played more than an…

Knee osteoarthritis is a degenerative condition with a significant disease burden and no disease-modifying therapy. Definitive treatment ultimately requires joint replacement. Therapies capable of regenerating cartilage could significantly reduce financial and clinical costs. The regenerative potential of mesenchymal s…

In the United States, half of all new human immunodeficiency virus (HIV) cases are among 13- to 24-year-old women. Heterosexual contact is the primary route of transmission (73%). Young African Americans account for 56% of reported HIV cases. In an earlier study, S. T. Roberts and B. L. Kennedy (2006) studied sexual de…

This study is significant because learning with mobile devices is increasing as a method of educating and training learners with visual impairments, but evaluation of its method is rare. In addition, the epistemological model used in this study is designed to improve future research designs. This article reviews the li…

The S-adenosylmethionine (AdoMet) analogue AdoMac [S-(5'-deoxy-5'-adenosyl)-1-ammonio-4-methylsulfonio-2-cyclopen ten e], an enzyme-activated, irreversible inhibitor of the Escherchia coli form of S-adenosylmethionine decarboxylase (AdoMet-DC), also acts as a potent inhibitor of the human form of the enzyme. This analo…
