An observational case-control study was conducted over 3 years, including 148 patients undergoing IVF treatment: 48 patients in the natural cycle (control group), 49 patients in the GnRH agonist protocol group (group 2) and 51 women in the GnRH antagonist protocol group (group 3). Blood and FF samples were collected on the day of oocyte retrieval and HIF-1α concentrations were assessed using enzyme-linked immunosorbent assay (ELISA). OHSS was diagnosed according to the Golan classification. Binomial logistic regression was used to show the change in the probability of OHSS associated with the concentration of HIF-1α. Finally, the ROC curve was created to check the usefulness of HIF-1α in the identification of OHSS. In all groups HIF-1α concentrations were lower in serum than in FF. There was no difference between the groups in the HIF-1α FF concentrations. Serum HIF-1α level was significantly lower in group 2 and 3 in comparison to the control group (320.35±148.83 pg/ml vs. 287.86±111.03 pg/ml and respectively vs. 490.38±249.36; p=0.0003 and p<0.000001).

Obesity is associated with changed mechanical properties of the chest potentially influencing breathing pattern. However, there is only limited information on changes in the breathing pattern in young individuals with obesity and the variability of the breathing pattern has not yet been investigated. Therefore, the aim of this study was to assess the breathing pattern changes in young individuals with obesity, focusing on its variability. We investigated 47 patients with obesity and 47 sex and age matched control subjects, mean age 17.6 years. Tidal volume and duration of inspiration and expiration were breath-to-breath recorded using respiratory inductive plethysmography method during five consecutive phases. Further we calculated following parameters: respiratory cycle duration (Ttot), respiratory rate (fR), minute ventilation (MV), the duty cycle (Ti/Ttot), mean inspiratory flow (Vt/Ti) and a measure of rapid shallow breathing (fR/Vt). Mean values of all respiratory parameters were used as representative values for the given phase and their variability was quantified using standard deviation (SD) and coefficient of variation (CV). Patients with obesity were characterized by reduced Vt and increased fR mostly at rest and by a decreased expiration duration resulting in an increase in Ti/Ttot ratio. While Vt/Ti did not differ between two groups, fR/Vt ratio was significantly increased in the obese group. Concerning respiratory variability, we found an increased variability of several respiratory parameters (respiratory rate, minute ventilation, inspiratory flow, Ti/Ttot ratio, fR/Vt ratio) in patients with obesity mostly at rest. We conclude that initial changes in breathing pattern and breathing pattern variability are already present in young patients with obesity.

The effects of Etomidate on myocardial tissue damage were evaluated by echocardiography, serum cardiac enzymes, myocardial hematoxylin and eosin (H&E) staining and Masson staining. Cardiomyocyte injury was determined by detecting cell viability and the levels of lactate dehydrogenase. Mitochondrial function of cardiomyocytes was assessed by mitochondrial membrane potential, adenosine triphosphate (ATP) content, and mitochondrial reactive oxygen species (ROS). Iron content, oxidative- and ferroptosis-related biomarkers were measured. Ferroptosis inducer Erastin was utilized for mechanistic investigation. In results Etomidate alleviated ischemia/reperfusion-induced myocardial injury, ferroptosis and mitochondrial injury in rats in a dose-dependent pattern. Etomidate also increased cell viability, attenuated mitochondrial damage, and reduced intracellular iron and lipid peroxidation in cardiomyocytes with hypoxia-reoxygenation (H/R) injury. Moreover, the protective effects of Etomidate against MI/RI or H/R injury were abolished by Erastin intervention. Our study elucidated the correlation between Etomidate and ferroptosis and mitochondrial damage following MI/RI, concluding that Etomidate may exert a protective effect against MI/RI by mitigating ferroptosis and mitochondrial damage.

Hippocampal Aβ deposition was detected using immunofluorescence. AD was modeled in vitro using a HT22 cells which are an immortalized cell line derived from primary mouse hippocampal neurons induced by Aβ1-42. Cell viability, apoptosis rate and LDH release were detected after etomidate intervention. Synaptic proteins were detected by mmunofluorescence or Western blot, and neurotransmitters and inflammatory factors were detected by ELISA. Etomidate improved the memory ability, novel object cognition ability, and spatial learning of APP/PS1 mice. The improvement of cognitive function and memory ability may be due to the recovery effect of etomidate on hippocampal pathological changes in APP/PS1 mice, including reducing Aβ deposition, neuron and synaptic loss. Etomidate also regulated neuroinflammation and the release of neurotransmitters GABA and 5-HT in APP/PS1 mice. Etomidate effectively reversed Aβ1-42-induced hippocampal neuronal damage, which was reflected in the improvement of cell viability and the inhibition of cytotoxicity, apoptosis and pro-inflammatory factors. Etomidate reversed the inhibition of the expression of synaptophysin (SYP) and postsynaptic density protein-95 (PSD-95) induced by Aβ1-42 in vitro.

Recently, the possible role of peroxisome proliferator-activated receptor (PPAR) ligands as potential regulators of endometrial inflammation has been proposed. The aim of the present study was to investigate the effect of PPARβ/δ ligands on mRNA abundance and protein secretion of selected inflammatory mediators - interleukin (IL)-1β, IL-6, IL-8, IL-4, IL-10, tumor necrosis factor alpha (TNF-α), leukemia inhibitory factor (LIF), toll-like receptor 4 (TLR4) and nuclear factor kappaB (NF-κB) - in porcine endometrium during physiology and lipopolysaccharide (LPS)-stimulated inflammation in both the mid-luteal and follicular phases of the estrous cycle. In addition, two experimental setups - an ongoing and a developing inflammation - were considered. Sections of endometrial tissue were incubated in vitro with two selected PPARβ/δ ligands: agonist L-165,041 or antagonist GSK 3787 with or without LPS. The mRNA abundance was determined by real time polymerase chain reaction (RT-PCR) and protein secretion in the culture medium by enzyme-linked immunosorbent assay (ELISA). Both PPARβ/δ ligands increased the mRNA abundance of IL-1β, IL-6 and IL-8 in the inflammatory state and decreased IL-4 protein secretion in the physiological state, mainly in the mid-luteal phase of the estrous cycle. In turn, only the antagonist increased TNF-α expression. For all proinflammatory cytokines - IL-1β, IL-6, IL-8, TNF-α - we found that both hormonal and inflammatory status significantly influenced their mRNA levels, while the experimental setup notably affected the expression of IL-1β, IL-6 and TNF-α. The results show that PPARβ/δ ligands modulate the expression and secretion of cytokines involved in the inflammatory response in the porcine endometrium. The main effect of PPARβ/δ ligands was noted during the mid-luteal phase of the estrous cycle. During LPS-stimulated inflammation, PPARβ/δ ligands appear to have pro-inflammatory properties by stimulating the expression of IL-1β, IL-6, IL-8, TNF-α.

The gene expression levels of IGF2BP2 in the samples were quantified using real-time quantitative reverse transcription PCR (qRT-PCR). The abilities of cell proliferation, apoptosis, migration, and invasion in human breast cancer cells (MBA-MD-231), as well as the expression of CCL20 and c-MYC following IGF2BP2 transfection, were measured. The binding of IGF2BP2 to CCL20 and c-MYC mRNA and the methylation levels of CCL20 and c-MYC after IGF2BP2 overexpression were detected using RNA immunoprecipitation-qRT-PCR (RIP-qRT-PCR). As a result, we found: 1) the expression of IGF2BP2 was elevated in all subtypes of breast cancer compared to the benign breast tumor group, with significant differences in the HER-2 overexpression and TNBC groups; 2) IGF2BP2 could promote cell proliferation, invasion, and migration capabilities. Notably, there was no significant difference in apoptosis rate in the experimental group with IGF2BP2 overexpression, while the apoptosis rate significantly increased in the experimental group where IGF2BP2 was silenced. The IGF2BP2 upregulated the expression of CCL20 and c-MYC, directly binding with both, with a significant increase in the methylation levels of CCL20 and c-MYC following IGF2BP2 overexpression. Our results indicate that IGF2BP2 exhibited differential expression across different molecular subtypes of breast cancer, with notable upregulation in triple-negative and HER-2 overexpression breast cancers. IGF2BP2 was found to promote the proliferation, invasion, and migration of TNBC, with no significant effect on apoptosis.

The histological analyses revealed the appearance of lipid droplets within the liver tissue of diabetic ZDF rats which were not observed in the non-diabetic control animals. Administration of both metformin and sea buckthorn caused a decrease in the number of lipid droplets in the liver. In ZDF rats, an increase in AST, ALP, bilirubin, cholesterol and triglyceride in blood serum was noticed.
