In the process of neoplasia, during which benign adrenal tumors are formed, stimulators of new blood vessel growth as well as growth of tumor cells are cytokines, especially tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6). We analyzed the expression profile of genes coding TNF-α, tumor necrosis factor receptor 1 (TNF-R1), TNF-R2, IL-6, interleukin 6 receptor (IL-6R) in sections of adrenocortical tumor tissue, rated on the Weiss point scale, in patients with clinically diagnosed Conn's and Cushing's syndrome, and the usefulness of determining the examined genes as markers differentiating individual clinical units. There was no correlation between the expression of the examined genes and clinical parameters such as age, BMI or blood pressure, both in the entire study group and in individual subgroups. Elevated expression of the genes coding TNF-α, TNF-R2 and IL-6R was observed, whereas genes encoding TNF-R1 and IL-6 showed relatively low expression. The highest statistically significant differences in the expression of the examined genes were observed between IL-6 and IL-6R. High positive correlation was found in the subgroup of patients with Conn's clinical syndrome, between genes encoding both types of receptors for TNF-α, IL-6 and TNF-R2, TNF-α and IL-6 receptor, and between TNF-R2 and IL6-R receptors, which may suggest the mutual influence of these cytokines and their receptors on their own expression.The lithium-pilocarpine model in rats is commonly used to study the characteristic events of acute status epilepticus (SE), epileptogenesis and temporal lobe epilepsy (TLE). Here we investigated the impact of lacosamide alone and in combination with other drugs (pregabalin, piracetam and scopolamine) on spontaneous recurrent seizures (SRSs) and behavioral parameters during the time frame of 6 weeks after SE. In addition, the level of oxidative stress in the hippocampus was accessed by real-time microdialysis study (8-isoprostanes) and antioxidants enzymes in the homogenate. Results revealed severe behavioral deficits with the control epileptic group and animals displayed hyperexcitability, aggression apprehension and memory insufficiency. Pharmacological manipulation for 6 weeks with lacosamide (L) - 80 mg/kg; in polypharmacy with pregabalin (L/P) - 50/50 mg/kg and piracetam (L/Pi) - 50/140 mg/kg significantly (P less then 0.05) ameliorated the anxiety-related behavior (open filed, elevated plus maze, lightost- SE insult.The abundance of research indicates that enriched environment acts as a beneficial factor reducing the risks of relapse in substance use disorder. There is also strong evidence showing the engagement of brain dopaminergic and glutamatergic signaling through the dopamine D2-like and metabotropic glutamate type 5 (mGlu5) receptors, respectively, that has a direct impact on drug reward and drug abstinence. The present study involved 3,4-methylendioxymethamphetamine (MDMA) self-administration with the yoked-triad procedure in rats kept under different housing conditions during abstinence - enriched environment (EE) or isolation cage (IC) conditions - aimed at evaluating changes in brain receptors affecting drug-seeking behavior as well as density and affinity of the D2-like and mGlu5 receptors in several regions of the animal brain. Our results show that exposure to EE conditions strongly reduced active lever presses during cue-induced drug-seeking. At the neurochemical level, we demonstrated marked decreases of D2-like receptor affinity in the dorsal striatum in rats previously self-administering MDMA under EE and increases in density under IC conditions. Moreover, we found the increases in the density and decreases in the affinity of the D2-like receptor in the prefrontal cortex and nucleus accumbens provoked by IC conditions. The mGlu5 receptor density decreased only in the prefrontal cortex after IC and EE abstinence. Moreover, our study has revealed a clear decrease in mGlu5 receptor density in the nucleus accumbens in the group actively administering MDMA only under EE conditions. This study demonstrates that housing conditions have impact on drug-seeking behavior in rats during abstinence from MDMA self-administration. The observed changes in the dopamine D2-like and mGlu5 receptor Bmax and/or Kd values were brain-region specific and related to either pharmacological and/or motivational features of MDMA.
  Immune-mediated diarrhea and colitis (IMDC) is a common immune-related adverse effect related to immune checkpoint inhibitors. We aimed to identify risk factors for chronic IMDC and its prognostic value in cancer outcomes.
 
  We retrospectively collected data on patients with a diagnosis of IMDC between January 2018 and October 2019 and grouped them based on disease duration into acute (≤3 months) and chronic (>3 months) categories. A logistic regression model and the Kaplan-Meier method with log-rank tests were used for biostatistical analysis.
 
  In our sample of 88 patients, 43 were in the chronic group and 45 were in the acute group. Genitourinary cancer and melanoma accounted for 70% of malignancies.  https://www.selleckchem.com/products/indisulam.html  PD-1/L1 monotherapy (52%) was the more frequently used regimen. We showed that chronic IMDC was associated with proton pump inhibitor use (odds ratio [OR], 3.96; P=.026), long duration of IMDC symptoms (OR, 1.05; P<.001) and hospitalization (OR, 1.07; P=.043), a histologic feature of chronic active colitis (OR, 4.8; P=.025) or microscopic colitis (OR, 5.0; P=.045), and delayed introduction of selective immunosuppressive therapy (infliximab/vedolizumab; OR, 1.06; P=.047). Chronic IMDC also reflected a better cancer response to immune checkpoint inhibitors (30% vs 51%; P=.002) and was accompanied by improved overall survival (P=.035). Similarly, higher doses of selective immunosuppressive therapy were associated with better overall survival (P=.018).
 
  Chronic IMDC can develop among patients with a more aggressive disease course and chronic features on colon histology. It likely reflects a prolonged immune checkpoint inhibitor effect and is associated with better cancer outcome and overall survival.
