Programmed cell death is a central process in the control of tissue development, organismal physiology, and disease. Ferroptosis is a recently identified form of programmed cell death that is uniquely defined by redox-active iron-dependent hydroxy-peroxidation of polyunsaturated fatty acid (PUFA)-containing phospholipids and a loss of lipid peroxidation repair capacity. This distinctive form of lipotoxic cell death has been recently implicated in multiple human diseases, spanning ischemia-reperfusion heart injury, brain damage, acute kidney injury, cancer, and asthma. Intriguingly, settings that have been associated with ferroptosis are linked to placental physiology and trophoblast injury. Such circumstances include hypoxia-reperfusion during placental development, physiological uterine contractions or pathological changes in placental bed perfusion, the abundance of trophoblastic iron, evidence for lipotoxicity during the pathophysiology of major placental disorders such as preeclampsia, fetal growth restriction, and preterm birth, and reduced glutathione peroxidation capacity and lipid peroxidation repair during placental injury. We recently interrogated placental ferroptosis in placental dysfunction in human and mouse pregnancy, dissected its relevance to placental injury, and validated the role of glutathione peroxidase-4 in guarding placental trophoblasts against ferroptotic injury. We also uncovered a role for the phospholipase PLA2G6 (PNPLA9) in attenuating trophoblast ferroptosis. Here, we summarize current data on trophoblast ferroptosis, and the role of several proteins and microRNAs as regulators of this process. Our text offers insights into new opportunities for regulating ferroptosis as a means for protecting placental trophoblasts against lipotoxic injury.
Ovarian cancer is the most lethal gynecologic malignancy due to the tumor's acquisition of chemoresistance to platinum-based chemotherapy. To solve this problem, we conducted RNAi-based large-scale screening and determined that tyrosine kinase with immunoglobulin-like and EGF-like domains 1 (TIE-1) is a key molecule involved in the platinum resistance of ovarian cancer cells. Recently, a variety of studies have investigated that small extracellular vesicles (sEVs) contribute to the communication between cancer cells, including the development of chemoresistance in ovarian cancer. The purpose of our study is to determine if sEVs-derived TIE-1 is involved in the chemoresistance of ovarian cancer cells.

TIE-1-overexpressed TOV112D cells, termed TOV112D
cells, were established, and sEVs were isolated from TOV112D
cells supernatants by ultracentrifugation. We assessed cisplatin sensitivity in recipient cells with TOV112D
-derived sEVs by cell-Titer Glo kit. We also asked whether sEV-derived TIE-1 suppressed the DNA damage response in recipient cells and evaluated the DNA damage response by counting cells positive for DNA damage foci.

TIE-1 was contained within sEV
derived from the cellular supernatant of TOV112D
. We showed that sEV-derived TIE-1 decreased chemosensitivity to cisplatin by suppressing the DNA damage response in recipient cells.

Our findings suggest that sEV-derived TIE-1 could be a new therapeutic target for refractory ovarian cancer.

Male breast cancer (MBC) accounts for 1% of all breast cancers and there is a paucity of data on factors impacting the treatment strategies and outcomes. We sought to use a large national database to examine trends and predictors of the use of adjuvant radiation (Adj-RT), as well as any association with outcome.

We queried the National Cancer Database (NCDB) for patients with stages I-III MBC treated with surgery (breast conservation surgery-BCS or mastectomy-MS) within 180 days of diagnosis (years 2004-2015). Multivariable logistic regression identified predictors of adj-RT receipt. Multivariable Cox regression evaluated predictors of survival. Propensity matching for adj-RT was used to account for indication biases.

We identified 6,217 patients meeting the eligibility criteria (1457 BCS vs. 4760 MS). The majority of patients were Caucasian (85%) and in an age range of 50-80 years (74%). Although adj-RT was omitted for 30% of BCS patients, the utilization was higher compared to MS (OR=26, p-value=0.001). The predictors of adj-RT use included African-American race, more advanced stage, higher grade, presence of lymphovascular invasion, and ER/Her-2 positivity for the entire cohort and increased age, urban location and higher income for BCS. Adj-RT was associated with lower mortality in the propensity matched model (overall HR for BCS=0.28, p-value<0.001; overall HR for MS=0.62, p-value=0.001).

This study demonstrates that while adj-RT after BCS is associated with decreased mortality in MBC patients, adj-RT is omitted in up to a third of cases of MBC after BCS despite being standard of care.

Serious toxicity associated with sunitinib is a rare situation. However; there are few cases reported in the literature. As a result of the inhibition that is caused by sunitinib malate agent at the receptor level, vascular endothelial growth factor (VEGF) level increases. These increased VEGF levels are considered to having a positive contribution on neurological side effects. Neurotoxicity that is related with the usage of sunitinib malate for two weeks will be presented in this case report.Dissolution fluxes of stable (127I) and radioactive (129I) isotopes of iodine from a brackish lake sediment beside a spent nuclear fuel reprocessing plant in Japan were evaluated through two kinds of experiments incubation using a sediment core sample for 24 h, and observation of 127I and 129I concentrations in sedimentary pore water. For 127I, the dissolution flux evaluated in the incubation experiment was comparable with that obtained from the vertical gradient of 127I concentration in pore water in the observation experiment. This suggests that degradation of organic matter in the surface sediment is an important source of dissolved 127I found in the water. For 129I, the dissolution flux estimated in the incubation experiment showed negative values, indicating the transfer of 129I to the sediment from the overlying water (i.e., absorption). Moreover, the flux evaluated from the observation experiment was positive. learn more This result suggests that degradation of organic matter in the surface sediment is scarcely important to the supply of 129I from the sediment to the water in the studied lake. The dissolution flux of 129I estimated in the observation experiment was smaller than the absorption flux of 129I in the incubation experiment. This potentially indicates that the dissolution of sedimentary 129I does not significantly change 129I concentrations in the water and sediment of the lake. This hypothesis was consistent with previous research conducted for the studied lake.The uptake of radionuclides by plants and their subsequent relocation to the human body through ingestion is one major pathway of human internal exposure. Thus, the present study was conducted to examine the levels of natural radionuclides, 238U and 232Th, in soil of Ezillo paddy fields (field 1 and field 2) at depths 0-4 cm and 4-8 cm, their transfer and accumulation in rice grains. The mean concentrations of both radionuclides in the soil were clearly greater than the UNSCEAR estimated worldwide average while that of the rice with values of 11.7 ± 4.3 and 3.0 ± 1.3 Bq/kg in field 1 and 8.5 ± 4.2 and 4.3 ± 1.6 Bq/kg in field 2 for 238U and 232Th respectively, were well below the worldwide average. The radionuclide transfer factors (TFs) across both depths ranged from 0.03 to 0.67 and 0.01 to 1.20 for 238U and 232Th respectively. The overall geometric means and geometric standard deviations of the TF estimated in field 1 were respectively 0.22 and 1.52 for 238U and 0.18 and 4.21 for 232Th (soil,0-4cm); 0.43 and 1.80 for 238U and 0.18 and 3.79 for 232Th (soil,4-8cm) whereas in field 2 the values were respectively 0.12 and 2.62 for 238U and 0.06 and 4.15 for 232Th (soil,0-4cm); 0.11 and 1.85 for 238U and 0.12 and 4.15 for 232Th (soil,4-8cm). The nuclide concentrations in the rice and the present TFs are within the ranges of values in the literature.The main techniques of animal product sampling used in different time periods after the Chernobyl accident are summarised and lessons learned from this analysis are presented. It was shown that simple instruments for measurement γ-radiation in the environment can also be effectively implemented for measurement of γ-emitters in animal products even though these were not originally developed to measure radioactivity in food. The lessons learned related to the major tasks of the monitoring such "what to sample", "where to sample" and "when to sample". The role and example of application of supplementary data on radionuclide of concern properties for sampling planning are also discussed. Based on the statistical analysis of the data obtained in the affected settlement it was shown that radionuclide concentration in the animal products can be fitted by the log-normal distributions whilst the dispersion of the logarithms of the activity 137Cs concentrations in milk is not dependent on the local settlement specific factors. Based on these findings the novel approach for justification of the number of samples that should to be taken to obtain the GM estimate with predefined precision for given variability of the data is suggested.Mycobacterium tuberculosis H37Ra (Mtb-Ra) ORF MRA_1916 is annotated as a D-amino acid oxidase (DAO). These enzymes perform conversion of d-amino acids to corresponding imino acids followed by conversion into α-keto-acids. In the present study Mtb-Ra recombinants with DAO knockout (KO) and knockout complemented with DAO over-expressing plasmid (KOC) were constructed. The growth studies showed loss of growth of KO in medium containing glycerol as a primary carbon source. Substituting glycerol with acetate or with FBS addition, restored the growth. Growth was also restored in complemented strain (KOC). KO showed increased permeability to hydrophilic dye EtBr and reduced biofilm formation. Also, its survival in macrophages was low. Phagosome maturation studies suggested enhanced colocalization of KO, compared to WT, with lysosomal marker cathepsin D. Also, an increased intensity of Rab5 and iNOS was observed in macrophages infected with KO, compared to WT and KOC. The in vivo survival studies showed no increase in CFU of KO. This is the first study to show functional relevance of DAO encoded by MRA_1916 for Mtb-Ra growth on glycerol, its permeability and biofilm formation. Also, this study clearly demonstrates that DAO deletion leads to Mtb-Ra failing to grow in macrophages and in mice.
