Objective: To evaluate the other pharmacological actions of silymarin in Albino rats and mice such as antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects. Methods: Rats were injected intramuscularly with pyrogenic dose of brewer's yeast for the antipyretic test of silymarin. Another group of rats injected with 0.1 mL of 1% carrageenan solution in saline at the subplanter area of the right hind paw for the antiinflammatory test of silymarin. Another group of mice tested by hot plate method for determination of antinociceptive effect of silymarin. Hyperlipidemia was induced using high fat diet for 2 months to estimate the antihyperlipidemic activity of silymarin. Results: Silymarin showed a significant antipyretic effect of both doses (50 and 100 mg/ kg) compared with control untreated group. Moreover, silymarin elucidated a significant anti-inflammatory effect of both doses reflected on the decrease of the rat paw edema every hour interval for 4 h after administration in comparison with control positive group. By the same taken, both doses of silymarine revealed a significant antinociceptive action in hot plate method at 30 and 60 min post administration. Besides, it lowered significantly the serum levels of prostaglandin E2, tumor necrosis factor alpha and interleukin 1 beta after 2 h of silymarin administration in carrageenan induced rat paw edema besides the significant decrease of total cholesterol, triglycerides, low density lipoprotein and significantly elevated high density lipoprotein after 2 weeks of silymarin administration. Conclusions: These outcomes delivered a new vision into the possible pharmacological mechanisms by which silymarin advances antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects.

Background:
Smoking is a preventable cause of chronic morbidity. Patient empowerment is a process through which people establish greater control over their health-related decisions and actions. To assess the effect of patient empowerment versus health education on the nicotine dependence score and progress of patients under different stages of smoking cessation.
Methods:
This was a single-blinded randomized controlled clinical trial that included 76 smokers attending family medicine clinics. Participants were divided into two groups: empowerment and health education groups. Their nicotine-dependence score and smoking cessation stage were identified. All study participants were subjected to five health education sessions with a 3-month follow-up period.
Results:
The mean nicotine-dependence score decreased significantly in both groups after the intervention. This decrease was slightly higher in the empowerment group; however, the difference was not statistically significant. After the intervention, 16.7% of the health education and 30.0% of the empowerment group transitioned from stage 1 to stages 2–4 of smoking cessation, with the change being statistically significant only in the empowerment group. There was no statistically significant difference in the number of study participants who stopped smoking between the health education and empowerment groups.
Conclusion
Both the empowerment model and traditional health education have similar positive effects on decreasing the nicotine-dependence level. There was a significant improvement in the stage of change for patients under the empowerment model, although there was no statistically significant difference between the groups regarding the number of participants who stopped smoking.

Clinical and Experimental Reproductive Medicine 2021;48(2):163-173
Objective:
This study aimed to characterize a validated model for predicting oocyte retrieval in controlled ovarian stimulation (COS) and to construct model-based nomograms for assistance in clinical decision-making regarding the gonadotropin protocol and dose.
Methods:
This observational, retrospective, cohort study included 636 women with primary unexplained infertility and a normal menstrual cycle who were attempting assisted reproductive therapy for the first time. The enrolled women were split into an index group (n=497) for model building and a validation group (n=139). The primary outcome was absolute oocyte count. The dose-response relationship was tested using modified Poisson, negative binomial, hybrid Poisson-Emax, and linear models. The validation group was similarly analyzed, and its results were compared to that of the index group.
Results:
The Poisson model with the log-link function demonstrated superior predictive performance and precision (Akaike information criterion, 2,704; λ=8.27; relative standard error (λ)=2.02%). The covariate analysis included women’s age (p<0.001), antral follicle count (p<0.001), basal follicle-stimulating hormone level (p<0.001), gonadotropin dose (p=0.042), and protocol type (p=0.002 and p<0.001 for short and antagonist protocols, respectively). The estimates from 500 bootstrap samples were close to those of the original model. The validation group (n=139) showed model assessment metrics comparable to the index model. Based on the fitted model, a static nomogram was built to improve visualization. In addition, a dynamic electronic tool was created for convenience of use.
Conclusion
Based on our validated model, nomograms were constructed to help clinicians individualize the stimulation protocol and gonadotropin doses in COS cycles.

OBJECTIVE: A numerical score, the peritoneal cancer index (PCI), was developed to reflect the extent of tumor growth in gastric and colorectal cancers and to tailor treatment. This study aimed to examine the value of the PCI score in advanced epithelial ovarian cancer (EOC) regarding completeness of surgical cytoreduction and survival. METHODS: This was a prospective observational cohort study. Patients with primary serous EOC at International Federation of Gynecology and Obstetrics (FIGO) stages IIIB or higher were included. Patients with FIGO stage IVB as well as those assigned to receive neoadjuvant treatment were excluded from the study. The PCI was obtained and registered intraoperatively. RESULTS: In the study period we recruited 96 patients with serous EOC stage IIIB–IVA. A PCI score cut-off value of 13 was calculated using a receiver operator characteristic (ROC) curve, above which worse survival is expected (area under the curve [AUC]=0.641; 95% confidence interval [CI]=0.517–0.765; sensitivity and specificity 80.6%, 45.0%, respectively; p=0.050). A multivariate analysis determined that suboptimal surgical cytoreduction was the only independent predictive factor for recurrence (odds ratio [OR]=7.548; 95% CI=1.473–38.675; p=0.015). A multivariate analysis determined that only suboptimal surgical cytoreduction (hazard ratio [HR]=2.33; 95% CI=0.616–8.795; p=0.005), but not PCI score >13 (HR=1.289; 95% CI=0.329–5.046; p=0.716), was an independent predictive factor for death. CONCLUSION: We conclude from this study that the PCI score is a reliable tool helping to assess the extent of disease in advanced serous EOC patients and may help predicting complete surgical cytoreduction but cannot qualify as a predictor of survival.

Treatment of AIDS (HIV) and hepatitis C virus needs protease inhibitors (PI) to prevent viral replication. Uses of PI in therapy are usually associated with a decrease in body weight and dyslipidemia. Acylation stimulating protein (ASP) is a protein synthesized in adipocytes to increase triglycerides biosynthesis, for that the relation of PI and ASP to adipogenesis is tested in this work. ASP expression was increased during 3T3-L1 differentiation and reached a peak at day 8 with cell maturation. Addition of PI during adipocytes differentiation dose dependently and significantly (p < 0.5) inhibited the degree of triglycerides (TG) accumulation. Moreover, presence of ASP (450 ng/mL) in media significantly (p < 0.5) stimulated the degree of TG accumulation and there was additive stimulation for ASP when added with insulin (10 microgram/mL). Finally, when ASP in different doses (Low, 16.7; Medium, 45 and High, 450 ng/mL) incubated with a dose of x150 PI, ASP partially inhibited the PI-inhibited adipogenesis and TG accumulation. The results in this study show that PI inhibit lipids accumulation and confirm role of ASP in TG biosynthesis and adipogenesis.

This report describes the echocardiographic features of an indirect Gerbode defect in a young cat. Echocardiography revealed high-velocity, turbulent systolic flow directed from left ventricle to right ventricle through a ventricular septal defect. The flow immediately entered the right atrium through a tricuspid septal leaflet. The indirect-type Gerbode defect was confirmed through necropsy. When a high-velocity turbulent flow in the RA without pulmonary hypertension is observed on echocardiography, Gerbode defect should be considered.

The course of Trichinella (T.) spiralis infection includes intestinal and muscle phases. The aims of this work were to evaluate IL-23 and cyclooxygenase-2 (COX-2) by immunohistochemistry in the muscles of T. spiralis infected mice in a time-course study and to correlate their level with the serum levels of IL-23, IFN-γ, IL-4 and IL-10 cytokines. The mice were divided into an un-infected control group (UC) (10 mice) and 5 infected mouse groups (each 10 mice/group. Each mouse was infected with 200 T. spiralis larvae) and sacrificed on days 7, 14, 21, 28 and 35 post-infection (dpi). IL-23 showed weak expression (+1) on the 21st dpi, then it became moderately expressed (+2) on the 28th dpi and on day 35 pi, the immunoreactivity was strong (+3). COX-2 expressed weakly on 14 dpi, while the other mouse groups (21, 28 and 35) showed strong (+3) expression. IL-23 serum concentrations increased gradually in a significant pattern, in comparison to that of UC mice, from the 21st dpi to the end of the experiment. IFN-γ increased gradually and was significantly higher than those of UC mice from the 7th dpi, reached its maximum level on the 21st dpi, after which it decreased non-significantly. IL-4 up-regulated significantly in all infected groups in comparison to UC mice achieving its highest level on the 21st dpi and decreased after that. IL-10 increased significantly on the 7th dpi, but dropped at the 14th dpi, then reached its peak on the 21st dpi, and decreased again on the 28th and 35th dpi. In conclusion, T. spiralis infection caused increased expression of IL-23 and COX-2 in the muscle of infected mice, the effect being strongest on the 35th day. Also, the infection induced a mixed Th1/Th2 profile with a predominance of Th2 at the early muscle phase, after which the immune repose became mainly Th2.
