As compared to non-IBD adenomas, IBD-associated dysplasia showed a significantly lower IL6, lower IL6R, higher STAT3, and lower SOCS3 expression. Most notably, a parallel-elevation pattern of STAT3/SOCS3 expressions was seen in non-IBD adenomas but an inverse-expression pattern of STAT3/SOCS3 seen in IBD dysplastic lesions. No significant differences existed between adenoma-like and non-adenoma-like lesions.
IL6/IL6R-STAT3-SOCS3 signaling pathway does not seem to be preferentially associated with IBD-associated dysplasia. However, the STAT3-SOCS3 interaction appears dysregulated in IBD, characterized by a loss of STAT3/SOCS3 balance,i.e., loss of the normal negative regulation of SOCS3.

The presence of microvascular invasion (MVI) is an unfavorable prognostic factor for hepatocellular carcinoma (HCC). This study aimed to construct a nomogram-based preoperative prediction model of MVI, thereby assisting to preoperatively select proper surgical procedures.
A total of 714 non-metastatic HCC patients undergoing radical hepatectomy were retrospectively selected from Zhongshan Hospital between 2010 and 2018, followed by random assignment into training (N = 520) and validation cohorts (N = 194). Nomogram-based prediction model for MVI risk was constructed by incorporating independent risk factors of MVI presence identified from multivariate backward logistic regression analysis in the training cohort. The performance of nomogram was evaluated by calibration curve and ROC curve. Finally, decision curve analysis (DCA) was used to determine the clinical utility of the nomogram.
In total, 503 (70.4%) patients presented MVI. Multivariate analysis in the training cohort revealed that age (OR 0.98), alpha-fetoprotein (≥400 ng/mL) (OR 2.34), tumor size (>5 cm) (OR 3.15), cirrhosis (OR 2.03) and γ-glutamyl transpeptidase (OR 1.61) were significantly associated with MVI presence. The incorporation of five risk factors into a nomogram-based preoperative estimation of MVI risk demonstrated satisfactory discriminative capacity, with C-index of 0.702 and 0.690 in training and validation cohorts, respectively. Calibration curve showed good agreement between actual and predicted MVI risks. Finally, DCA revealed the clinical utility of the nomogram.
The nomogram showed a satisfactory discriminative capacity of MVI risk in HCC patients, and could be used to preoperatively estimate MVI risk, thereby establishing more rational therapeutic strategies.

Liraglutide, a glucagon-like peptide-1 (GLP-1) analog, is commonly used to treat insulin-resistant diabetes. In this study, for the first time, we showed that liraglutide remarkably improved the antitumor immune responses in hepatocellular carcinoma (HCC). Furthermore, we showed that the antitumor activity was mediated by nature killer cells (NKs) but not CD8+ T cells. Finally, we showed that liraglutide enhanced NK-mediated cytotoxicity by suppressing the IL-6/STAT3 signaling pathway in HCC cells. Our findings unveil a novel therapeutic role of liraglutide by manipulating the innate immunity in cancer therapy.This study aimed to investigate the acaricidal activity of (E)-cinnamaldehyde and α-bisabolol on populations of Rhipicephalus microplus with different resistance profiles. The adult immersion test (AIT) was used to characterize the susceptibility of tick populations (50 field populations) to synthetic acaricides deltamethrin, amitraz, and chlorfenvinphos. The larval packet test (LPT) was used to determine the LC50 values for (E)-cinnamaldehyde (populations 1-25) and α-bisabolol (populations 26-50) at the concentrations of 0.31, 0.62, 1.25, 2.0, 2.5, 5.0 and 10.0 mg/mL. The susceptible strain Porto Alegre (POA) was used as a reference for calculating the resistance ratio (RR). In the AIT, deltamethrin did not show efficacy >95 % for any of the populations, whereas amitraz and chlorfenvinphos have presented efficacy >95 % for three (6 %) and 15 (30 %) populations, respectively. In the LPT, the LC50 values of (E)-cinnamaldehyde and α-bisabolol varied from 0.23 to 2.36 mg/mL and 1.57-3.01 mg/mL, respectively. The RR50 for (E)-cinnamaldehyde showed 20 (80 %) populations with values 1.5. As for α-bisabolol, only two (8%) populations have presented RR50 less then 1.0, whereas three (12 %) populations showed incipient resistance to this sesquiterpene (RR50 between 1.5 and 2.0). The results indicate that all studied tick populations showed low susceptibility to at least one of the commercial acaricides tested. In addition, comparison between the LC50 values of (E)-cinnamaldehyde and α-bisabolol for the field populations and the susceptible strain POA suggests that there is no cross-resistance of (E)-cinnamaldehyde and α-bisabolol for the tick populations evaluated, and that the differences in the LC50 values are due to population variations.Coccidiosis is considered to be one of the most important challenge in the poultry industry causes economic losses due to the destruction in the digestive tract of chicken. It disturbs amino acids profile and their digestibility, leading to weight lost and economic burden. Using dietary arginine may decrease the adverse effects of coccidiosis on chicken digestive tract. This study aimed to evaluate the effects of dietary inclusion of arginine on intestine histological parameters, serum amino acid concentration and ileal amino acid digestibility of broiler chicks infected with coccidiosis. A total number of 384 one-d-old broiler chicks (Ross 308) of mixed sex with initial weight of 42 ± 2 g was allocated into 8 groups with 8 birds/pen from grower period. At 21 days of age, broiler chicks were infected with a mixture of Eimeria spp. Broiler chicks were divided into infected and un-infected groups and received arginine at recommended levels of 85, 100, 125 and 150 %. Intestinal morphology and lesions, serum amino acid concentration and ileal amino acid digestibility were evaluated. Broiler chicks infected with Eimeria spp. showed lower villus height and villus height crypt depth ratio and also higher intestinal lesions (P 0.05). In sum, coccidiosis decreases amino acid digestibility and serum amino acid concentration, but dietary inclusion of higher levels of arginine significantly improved histological parameters of broiler chicks infected with coccidiosis.Toxoplasma gondii infections are common in humans and animals worldwide. The present review summarizes worldwide information on the prevalence of clinical and subclinical infections, epidemiology, diagnosis, control, and genetic diversity of T. gondii in sheep in the past decade. There is debate and uncertainty concerning repeat congenital infection as evidenced by finding T. gondii DNA in progeny of chronically infected sheep. However, there is no concrete evidence that T. gondii is the cause of repeated abortions in sheep. Recent data concerning pathogenesis of abortion in acutely infected sheep are reviewed. PCR-RFLP typing of T. gondii DNA derived from viable T. gondii isolates or tissues of infected sheep revealed low genetic diversity in sheep in Europe, Africa, Asia and North America but high diversity in South America. This review will be of interest to biologists, parasitologists, veterinarians, and public health workers.Pisa syndrome (PS) is a postural deformity characterized by marked and reversible lateral trunk flexion. PS can be seen in Parkinson's disease (PD) and several neurodegenerative diseases. A scoping systematic review was conducted to view the therapeutic interventions for PS in PD, their effectiveness, outcome measurements, and related cofactors. Databases and manual searches were performed. Studies that evaluate the effect of interventions on PS were included. Data were extracted and categorized by the main applied therapeutic intervention. A total of 19 published and 2 unpublished studies met the inclusion criteria. Wall and traditional goniometer, kinematic analysis, and clinical observations were used to detect PS. The included studies applied the following therapeutic protocols Deep brain stimulation (DBS), Botulinum toxin injection, posture exercises, lidocaine injection, oculomotor correction, and spinal cord stimulation. The outcomes measurements of the included studies were linked to International Classification of Functioning, Disability and Health (ICF) model. The therapeutic interventions variously improve PS outcomes at short and long-term follow-up. The interventions did not report side effects or adverse events except DBS. PS severity was related to the DBS voltage amount in one study, and one participant in another study relapsed due to DBS. There are missing reported data in terms of participants' characteristics, medication status, and side effects. The current evidence shows the available interventions for PS, outcomes measurements, and related cofactors. The interventions may be safe and beneficial for PS. Further powerful studies are required.
Transradial access has recently been gaining more popularity in various neurointerventional procedures. To this day, a systematic review and meta-analysis investigating the outcomes of transradial access for mechanical thrombectomy in acute stroke have not been performed.
PubMed, Embase, and Scopus databases were systematically searched. Studies published in the last ten years reporting on the use of transradial access for acute stroke intervention were eligible. The DerSimonian-Laird random effects model was used, and the primary endpoints included puncture to reperfusion time, end mRS, TICI reperfusion, mortality, and access site complications.
A total of 515 records were identified. Fourteen observational studies reported on the use of radial access for thrombectomy, with 10 of these studies (n = 309) included in the meta-analysis. Mean puncture to reperfusion time associated with the transradial access was 46.864 ± 6.601 min. Favorable end mRS of ≤ 2 was reported in 37.1 % ± 7.3 % of patients. TICI ≥ 2B was achieved in 84.6 % ± 3.4 % of patients. All-cause mortality was observed in 9.3 % ± 4.8 % of patients. Transradial access had low complications with only 1.4 % ± 0.7 % of stroke cases. When the transradial studies were compared to the contemporary randomized clinical trials using the standard transfemoral access, no significant differences were found in all of these primary outcomes.
This meta-analysis study demonstrates that transradial access for mechanical thrombectomy in acute stroke may be a feasible and safe alternative. Future prospective studies are needed to validate these results.
