Urate Transporter 1 (URAT1) plays a crucial role in uric acid transport, making it an attractive target for the treatment of gout and hyperuricemia. As a representative URAT1 inhibitor, Lesinurad treat gout by promoting the uric acid excretion. However, its lower in vitro and in vivo activity should be highly attracted attention. Herein, the bioisosterism, molecular hybridization and scaffold hopping strategies were exploited to modify all the structural components of Lesinurad and finally thirty novel compounds bearing thienopyrimidinone or pyridine core were obtained. Most of the compounds displayed certain URAT1 inhibitory activity in vitro. Among them, thienopyrimidinones 6 (IC50 = 7.68 μM), 10 (IC50 = 7.56 μM), 14 (IC50 = 7.31 μM) and 15 (IC50 = 7.90 μM) showed slightly better potency than positive control Lesinurad (IC50 = 9.38 μM). Notably, 10 also displayed inhibitory activity (IC50 = 55.96 μM) against GLUT9. Additionally, in vivo serum uric acid (SUA)-lowering experiments were performed on some representative compounds and it was revealed that all the selected compounds could decrease the SUA level in mice, of which the decrease rate of SUA was 73.29% for the most promising compound 10, significantly greater than that of Lesinurad (26.89%). Meanwhile, the preliminary SARs based on the URAT1 inhibitory activity were discussed in detail, which pointed out the direction for further structural optimization. Overall, the thienopyrimidinone and pyridine are prospective skeletons for the developing novel URAT1 inhibitors with considerable potential for optimization.In search of novel osteogenic entities, a series of twenty-seven quinazolinone-benzopyran-indole hybrids were designed and synthesized using molecular hybridization approach. All the compounds were scrutinized for their osteogenic potential, primarily based on alkaline phosphatase assay as one of the major anabolic markers. From the primary screening, four osteogenic compounds were sorted from the series and were found nontoxic to the osteoblasts. Further, increased osteoblast differentiation and osteogenic mRNA upregulations suggest compound 47 as the most potent osteoanabolic agent. Immunoblot and ELISA analysis demonstrated that compound 47 promotes osteogenesis via RUNX2 and BMP2 mediated non-canonical p38 pathway. In vivo studies in BALB/c mice inferred that compound 47 stimulates bone anabolism as evident from histological and gene expression studies at 5 mg. kg-1. day-1 dose. Furthermore, structural activity relationship (SAR) and pharmacokinetic studies suggest compound 47 as a BMP2 upregulator and a potential bone anabolic lead for combating future bone metabolic disorders.Borderline Personality Disorder is a severe psychiatric disorder with debilitating consequences. Screening for the disorder is problematic as symptoms overlap with other psychiatric disorders. The McLean Screening Instrument (MSI) assesses endorsement (yes/no) of 10 symptoms, with a cut-off of seven indicating potential caseness. Participants were (N = 68) from an established clinical cohort who completed a structured clinical interview, the MSI, the Childhood Trauma Questionnaire, and the Adolescent and Adult Time Attitudes Scale. A proportion (N = 20) also completed a follow-up interview examining their rationale for endorsing MSI items. Total number of MSI items endorsed was meaningfully related to scores on emotional neglect and negative time attitudes. There was substantive overlap between MSI threshold (≥7 items) and lifetime diagnosis of a mental disorder. The stated rationale for endorsing MSI items, was less indicative of personality trait, and was related more to particular developmental periods, one-off episodes, and life-contexts. Additionally, participants conflated constructs such as emptiness with loneliness, and moodiness with general emotionality. Those meeting MSI threshold recalled more childhood emotional neglect, and were more negative about all time periods. It is apparent that scoring of the MSI is driven by prevailing life circumstances as much as enduring personality traits.Depression is common in schizophrenia and is correlated with suicide risk and poor long-term outcomes. However, the presence of depressive symptoms is often underestimated in both research and treatment, particularly at the illness onset. The goals of this study were (a) to longitudinally observe anxious-depressive symptom levels in patients with First Episode Schizophrenia (FES) during a 24 months of follow-up period, and (b) to examine their associations with other psychopathology and the intervention patients received in an "Early Intervention in Psychosis" (EIP) program during the follow-up period. The Global Assessment of Functioning (GAF) and the Positive And Negative Syndrome Scale (PANSS) were completed by 159 FES patients both at baseline and across the follow-up. Data were analyzed by linear regression analysis and Spearman's coefficients. Anxious-depressive symptoms had significant longitudinal associations with GAF deterioration and PANSS "Positive Symptoms", "Negative Symptoms" and "Disorganization" subscores. During the follow-up period, FES participants significantly improved the level of anxious-depressive symptoms. This was significantly associated with the number of case management and individual psychotherapy meetings the patient engaged in, as well as with lower antipsychotic doses prescribed during the follow-up period. In conclusion, anxious-depressive symptoms are prominent in FES and at the initial entry into EIP programs. HG106 compound library inhibitor Anxious-depressive symptom severity tends to diminish overtime, especially with the provision of specialized EIP treatments. However, since we did not have a control population studied in parallel, we cannot say whether these results are specific to the protocols of EIP programs or just to the intensity of engagement in care.Obesity causes epigenetic alterations mediated by non-coding RNAs (ncRNAs) that increase susceptibility to autoimmune and inflammatory pathways. Obese individuals with rheumatoid arthritis (RA) are particularly affected, with worse clinical outcomes and treatment responses. In order to identify micro RNAs (miRNAs) and long ncRNAs (lncRNAs) that may influence RA development, progression, treatment efficacy, and clinical outcomes in obese individuals, we systematically screened PubMed, Web of Science, and Scopus databases for articles on these topics, published in the last decade. We ended up with 38 of initially 1110 documents and found that both obesity and RA share dysregulated expression of miR-21, miR-143, miR-146a, miR-155 miRNAs, H19, and HOTAIR lncRNAs (all but H19, up-regulated). With one exception (H19 and BMI in brown fat tissue), they correlated positively with clinical measures and disease activity. H19 and HOTAIR regulate 24 miRNAs, some differentially expressed in the investigated diseases. Both regulate miR-143-3p. We also investigated eleven GWAS-identified SNVs found in exonic lncRNA regions (there were none in exonic miRNA genes). Eight were associated with RA and three with obesity-related traits, seven change binding sites for miRNAs, especially on LINC01184 and GATA3-AS1, four were associated with gene expression in adipocytes (including LINC01184) and two may also change the secondary structure of ENSG00000284825 and LINC02656. These ncRNAs compose a unique regulatory network in obese RA patients, compiled for the first time in this review, which we suggest as future therapeutic targets in these simultaneous conditions.

Dyspnea, the cardinal manifestation of chronic heart failure (CHF), may reflect both pulmonary oedema and pulmonary remodeling resulting in tissue stiffening. Emerging evidence suggests that predominance of distinct phenotypes of alveolar and recruited macrophages, designated M1 and M2, may regulate the course of inflammatory tissue repair and remodeling in the lung.

In a CHF rat model, we found fibrotic reinforcement of the extracellular matrix with an increase in monocyte chemotactic protein (MCP)-1/CCL2 in bronchoalveolar lavage (BAL), corresponding to a 3-fold increase in recruited macrophages. In this clinical cross sectional study, we aimed to examine potential mediators of leukocyte activation and lung infiltration in parallel BAL and blood from CHF patients compared to non-CHF controls.

Mini-BAL and peripheral blood samples were obtained from hospitalized CHF, acute decompensated CHF and non-CHF patients. CHF patients and decompensated CHF patients demonstrated increases from non-CHF patients in BAL MCP-1, as well as the M2 macrophage cytokines interleukin-10 and transforming growth factor-β. BAL and plasma MCP-1 were significantly correlated; however, MCP-1 was 20-fold higher in epithelial lining fluid in BAL, indicative of an alveolar chemotactic gradient. An increase in transglutaminase 2 positive M2 macrophages in parallel with a decrease in the MCP-1 receptor, CC chemokine receptor 2 (CCR2), was apparent in BAL cells of CHF patients compared to non-CHF.

These data suggest a pathway of MCP-1 mediated M2 macrophage prevalence in the lungs of CHF patients which may contribute to pulmonary fibrotic remodeling and consequent increased severity of dyspnea.

Twelve Ossimi rams were subjected to either a single administration of long-acting FSH subcutaneously (FSH group; n = 6) or the vehicle (control group; n = 6). Assessment of testicular hemodynamics at the level of the supratesticular artery was performed just before administration (0 h), and at 4, 24, 48, 72, 96, and 168 h after FSH or the vehicle administrations. Testicular volume (TV), and echotexture of testicular parenchyma including pixel intensity and heterogeneity were derived by the computer analysis software. Concentrations of T, E2, and NO were measured using commercial kits. Results revealed significant decreases (P ˂ 0.05) in the values of Doppler indices (resistive index RI and pulsatility index PI), especially at 48 h after administration of FSH (RI 0.42 ± 0.02, PI 0.56 ± 0.04) compared to their values in the control group (RI 0.54 ± 0.03, PI 0.77 ± 0.04). FSH administration induced significant decreases (P ˂ 0.05) in the pixel intensity of testicular parenchyma. Testicular volume and T concentrations were not significantly changed (P ˃ 0.05). Concentrations of E2 increased significantly (P ˂ 0.05) at 48 h and 72 h after FSH administration. (30.07 ± 5.23 pg/ml, 29.93 ± 1.44 pg/ml, respectively) compared to their values before FSH administration (14.63 ± 1.37 pg/ml). Concentrations of NO increased significantly (P ˂ 0.05) in the FSH group between 4 h to 48 h compared to the values in the control one. In conclusion, a single administration of long-acting FSH enhanced testicular blood perfusion as measured by pulsed Doppler ultrasonography in rams during the non-breeding season. Concurrently, significant increases in the concentrations of E2 and NO were found.
