These findings suggest that liquiritigenin can inhibit malignant behavior of triple negative breast cancer cells by inhibiting DNMT activity and increasing BRCA1 expression and its transcriptional activity. Liquiritigenin thus may be a promising candidate for the treatment of breast cancer.Endogenous hydrogen sulfide (H2S) affects cholesterol homeostasis and liver X receptor α (LXRα) expression. However, whether low-density lipoprotein (LDL) receptor (LDLR), a key player in cholesterol homeostasis, is regulated by exogenous H2S through LXRα signaling has not been determined. We investigated the effects of sodium hydrosulfide (NaHS, H2S donor) on LDLR expression in the presence or absence of LXR agonists, T0901317 or GW3965 in HepG2 cells. We found that H2S strongly accumulated LDLR precursor in the presence of T0901317. Hence, LDLR transcription and the genes involved in LDLR precursor maturation and degradation were studied. T0901317 increased the LDLR mRNA level, whereas H2S did not affect LDLR transcription. H2S had no significant effect on the expression of LXRα and inducible degrader of LDLR (IDOL). H2S and T0901317 altered mRNA levels of several enzymes for N- and O-glycosylation and endoplasmic reticulum (ER) chaperones assisting LDLR maturation, but did not affect their protein levels. H2S decreased proprotein convertase subtilisin/kexin type 9 (PCSK9) protein levels and its mRNA level elevated by T0901317. T0901317 with PCSK9 siRNA also accumulated LDLR precursor as did T0901317 with H2S. High glucose increased PCSK9 protein levels and attenuated LDLR precursor accumulation induced by T0901317 with H2S. Taken together, H2S accumulates LDLR precursor by downregulating PCSK9 expression but not through the LXRα-IDOL pathway, LDLR transcriptional activation, or dysfunction of glycosylation enzymes and ER chaperones. These results also indicate that PCSK9 plays an important role in LDLR maturation in addition to its well-known effect on the degradation of LDLR mature form.Aim DNA methylation testing for endometrial cancer detection in minimally invasive specimens is a promising tool to improve screening and diagnostic procedures. Available literature was systematically reviewed to assess the potential of this approach and define methylation markers deserving further development. Methods A systematic search up to March 31 2020 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results 15 methylation markers with an area under the curve value of ≥ 0.80 for endometrial cancer detection in cytological specimens were selected from nine studies. Conclusion Detection of methylation markers in cytological samples indicate the feasibility of minimally invasive testing methods, potentially guiding diagnosis and detection of endometrial cancer in high-risk women and in cancer screening programs.

Preoperative portal vein embolization (PVE) is performed to induce hypertrophy of the future liver remnant enabling major liver resection in patients with various types of liver tumors.

To evaluate safety and effectiveness of PVE with n-butyl-cyanoacrylate (NBCA).

All consecutive patients referred to our hospital for PVE between July 2006 and July 2017 were retrospectively reviewed. Volumetry was performed on computed tomography images before and after PVE, segmenting the total liver volume and the future liver remnant (FLR), i.e. liver segments I-III.

PVE was performed in 46 patients (18 women, 28 men; mean age = 61 years) using local anesthesia. The ipsilateral technique was used in 45 patients. Adverse events were rare. The mean FLR volume increase was 56%, the degree of hypertrophy was 9.7%, and the kinetic growth rate was 2.1%/week. selleck The median ± SD period between PVE and liver surgery was 7 ± 3 weeks. Forty-two patients (91%) had surgery; liver resection was performed in 37 (80%) patients. Three patients (7%) developed transient liver failure after surgery. There was no 90-day post-PVE or postoperative mortality.

PVE using NBCA through the ipsilateral approach in local anesthesia is safe and effective in inducing hypertrophy of the future liver remnant enabling surgery, and thereby increasing survival in patients with liver tumors.

Iliotibial band friction syndrome (ITBFS) is an overuse injury of the lateral aspect of the knee. This syndrome classically affects the active young population.

To determine the diameter of the ITB using magnetic resonance imaging (MRI) in patients clinically diagnosed with ITBFS, compare the results with asymptomatic patients, and assess the inter-observer agreement between a senior and a junior radiologist with different levels of experience in musculoskeletal imaging.

From April 2014 to October 2019, 78 knee MRI scans of 78 patients were included in the study group who were referred from the orthopedic clinic with a clinical diagnosis of ITBFS. In the control group, there were 114 knee MRI scans of 114 patients who had knee MRI for various reasons and had no radiological abnormality on the performed knee MRI. The ITB diameters, cut-off values, and interclass correlation coefficient (ICC) were calculated.

Mean thickness of the ITB was higher in the study group compared to the control group in measurements done by both the senior and junior radiologists and this was statistically significant (

 < 0.001). Cut-off values of the diameters of the ITB were calculated as 2.385 for the senior radiologist and 2.420 for the junior radiologist. ICC of 0.80 was determined, which showed excellent agreement among interpreters.

ITB thickness in the study group was significantly higher than in the control group. There was also excellent agreement among the two observers. Measurement of ITB thickness on axial plane knee MRI is one of the reliable criteria for ITBFS.
