Diamond Blackfan anemia (DBA) is caused by germline heterozygous loss-of-function pathogenic variants (PVs) in ribosomal protein (RP) genes, most commonly and . In addition to red cell aplasia, individuals with DBA are at increased risk of various cancers. Importantly, the mechanism(s) underlying cancer predisposition are poorly understood.

This study was conducted to evaluate the changes in stigmatizing attitudes of nursing students who took the addiction course toward individuals with substance use disorder.
Method: The study was conducted in a single group in a pretest-posttest order.
Background: Clinical clerkships lie at the core of nursing education and are crucial for developing professional skills. However, nursing students, especially freshmen, often encounter significant stress during their clinical experiences.
Objectives: This study investigated the effect of a stress management program on first-year nursing students' clinical stress levels.
Purpose: To assess the effect of a program designed to reduce nursing students' social distancing from individuals diagnosed with schizophrenia.
Method: This experimental study was designed using a pretest, a posttest, and a control group. All participants were nursing students, of which 25 were included in the intervention group and 23 were placed in the control group.

Aim: This study aims to describe nurses' views on what it is like to be a working mother in Turkey.
Background: Most mothers are in the workforce but continue to fulfil their traditional roles at home. This emerges as an important factor causing mothers to try to find a balance between work and home.

Development of biocompatible and multifunctional nanoprobes for tumor targeting, imaging, and therapy still remains a great challenge. Herein, gold nanoparticles (AuNPs) were synthesized in the cavity of horse spleen apoferritin protein (HoSAF) and protein surface was labeled with 2-amino-2-deoxy-glucose (2DG) as a cell surface glucose transport protein specific targeting probe to study the feasibility of its usage as a computer tomography (CT) contrast agent with tumor targeting capability through in vitro experiments. 2DG conjugated and gold-loaded apoferritin (Au-HoSAF-2DG) nanoparticles (NPs) showed selective targeting for human breast adenocarcinoma (MCF-7) cells when compared to normal breast (MCF-10A) cells.

Later experimental and clinical evidence suggested that Src kinase plays a significant role in promoting tumor growth and progression and its activity is associated with poor patient survival. Thus, several Src inhibitors were developed and approved by FDA for treatment of cancer patients.

This study was conducted to determine the effects of a psychoeducation programme for emotion identification and expression in those diagnosed with schizophrenia on their ability to identify and discriminate between emotions and social functionality. This quasi-experimental study (pretest-post-test, with control group) comprised an intervention (21) and a control (21) group conducted with individuals diagnosed with schizophrenia.

Infertile women feel more psychological stress and pressure than their husbands, and the prevalence of anxiety and depression among them are higher. This study aimed to develop a culture-specific measurement tool to identify the strategies of infertile women in dealing with infertility-related problems. This was a scale development study.

Re-magnetoferritin nanoparticles (NPs) provide an attractive platform for localized radiation therapy due to their magnetic targeting capability while enhancing contrast in magnetic resonans imaging (MRI) signals. In this study, cellular uptake, in vitro cytotoxicity, apoptotic potential of a non-radioactive isotope of rhenium in the form of Re-magnetoferritin NPs were evaluated in both human normal mammary epithelial and breast metastatic adenocarcinoma cell lines. The results showed that, NP administration into the cells is through receptor mediated endocytosis and cancer cells displayed significantly higher uptake and cytotoxicity compared to normal cells.

Materials & Methods: We synthesized a highly monodisperse nanoformulation using polyethylenimine-modified gold nanoparticles (AuNP-PEI) as siRNA delivery vehicle and evaluated gene downregulation.
Results: We found that AuNP-PEI/eEF-2K nanoformulation was highly effective for in vitro and in vivo gene downregulation and showed remarkable antitumor efficacy that was associated with eEF-2K knockdown, inhibition of Src and MAPK-ERK signaling pathways in a TNBC orthotopic tumor model.
Magnetic nanoparticles (MNPs) have been increasingly used for many years as MRI agents and for gene delivery and hyperthermia therapy, although there have been conflicting results on their safety. In this study, cobalt ferrite magnetic nanoparticles (CoFe-MNPs) were prepared by the co-precipitation method and their surfaces were modified with silica by the sol-gel method. The particle and hydrodynamic sizes, morphology and crystal structure of the bare and silica-coated CoFe-MNPs were evaluated by transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray diffraction spectroscopy (XRD) and Fourier transform infrared spectroscopy (FTIR).

According to our results, it is apparent that, 2DG labeled MNPs were internalized more efficiently than COOH-MNPs under the same conditions in all cell types (MDA-MB-231 and MCF-7 cancer and MCF-10A normal breast cells) (p<0.001).

Fetal intra-abdominal umbilical vein varix (FIUVV) is a focal aneurysmal dilatation of the umbilical vein. Its clinical importance has not yet been clearly established, but it has been reported to be associated with increased fetal death rate (in nearly 44% of cases) and chromosomal abnormalities (in 12% of cases). We report 2 cases of FIUVV diagnosed via sonography in the third trimester.
