BACKGROUND Telotristat ethyl is approved to treat carcinoid syndrome diarrhea in combination with somatostatin analogs. In TELESTAR and TELECAST phase III studies, patients with carcinoid syndrome received telotristat ethyl 250 or 500 mg 3 times per day (tid) or placebo tid in addition to somatostatin analogs. The aim of this prespecified analysis was to examine the time to reductions in bowel movements (BMs) in the TELESTAR and TELECAST studies using survival analysis methods. METHODS First occurrence of sustained response was defined as the time to the first day of 2 consecutive weeks with a mean BM frequency improvement of ≥ 30% from baseline during the 12-week double-blind treatment periods. Time to first ≥ 30% worsening in BM frequency was also measured. Selleckchem Ifenprodil Treatments were compared with the log-rank test; Cox regression models provided point and confidence interval estimates of the hazard ratios for each trial. RESULTS In TELESTAR and TELECAST, majority of patients (69%) on telotristat ethyl experienced a sustained ≥ 30% improvement in BM frequency. The median time to sustained reduction of at least 30% in BM frequency was significantly faster (fewer days to onset) for telotristat ethyl compared with placebo in both TELESTAR (250 mg, HR = 2.3 [95% CI, 1.3-4.1, P = 0.004]; 500 mg, HR = 2.2 [95% CI, 1.2-3.9, P = 0.009]) and TELECAST (250 mg, HR = 3.9 [95% CI, 1.6-11.1, P = 0.003]; 500 mg, HR = 4.2 [95% CI, 1.7-11.7, P = 0.002]). In TELECAST, 42% of patients on placebo experienced sustained worsening in BM frequency compared with 20% on telotristat ethyl; no significant difference was observed in TELESTAR. CONCLUSION The time of onset of sustained BM frequency improvement mean and range are important when considering use of telotristat ethyl in patients with carcinoid syndrome diarrhea. Telotristat ethyl may also reduce sustained worsening in BM frequency.

Natural selection can enhance specific cognitive abilities depending on species ecology but, under certain conditions, spatial learning is also known to vary between sexes according to reproductive status. Despite abundant studies on spatial learning across animal taxa, those focusing on sexually dimorphic spatial learning have been largely limited to rodents. Here, we found that spatial cognition varies between the sexes in an intertidal goby, and this difference fluctuates across seasons. Males and females demonstrated similar cognitive abilities when solving a simple maze during all seasons except spring, when males were significantly less successful than females. Spring marks the beginning of the breeding season for this species, when females move between nests to choose a suitable mate, while males guard their nest and forego foraging excursions. We suggest that the reduction in male cognitive ability reduces metabolic costs at a time of reduced need. This study presents the first evidence for sexually dimorphic spatial learning in fish driven by differences in reproductive behaviour as dictated by the mating system.In multicellular organisms, not all cells are created equal. Instead, organismal complexity is achieved by specialisation and division of labour between distinct cell types. Therefore, the organism depends on the presence, correct proportion and function of all cell types. It follows that early development is geared towards setting up the basic body plan and to specify cell lineages. Since plants employ a post-embryonic mode of development, the continuous growth and addition of new organs require a source of new cells, as well as a strict regulation of cellular composition throughout the entire life-cycle. To meet these demands, evolution has brought about complex regulatory systems to maintain and control continuously active stem cell systems. Here, we review recent work on the mechanisms of non cell-autonomous control of shoot stem cells in the model plant Arabidopsis thaliana with a strong focus on the cell-to-cell mobility and function of the WUSCHEL homeodomain transcription factor.INTRODUCTION Primary Sjögren's syndrome (pSS) has been related to a higher risk of comorbidities, but studies examining comorbidities among patients with and without extraglandular manifestations are limited. The objectives of this study were to assess the prevalence of comorbidities in Chinese pSS patients and to determine the relationship between comorbidities and extraglandular manifestations. METHOD This cross-sectional study was based on the multicenter pSS registry established by the Chinese Rheumatism Data Center. Patients fulfilling the 2002 American-European criteria or the 2016 classification criteria for pSS were enrolled from May 2016 to December 2018. Demographic data, disease characteristics, comorbidities (cardiovascular disease, thyroid disorder, malignancy, and fragility fracture), and extraglandular manifestations were collected. Multivariate analyses were used to assess the relationships between comorbidities and extraglandular manifestations. RESULTS A total of 4087 pSS patients were incluon the largest pSS registry in China.• Patients with multiple extraglandular manifestations tend to have increased comorbid cardiovascular disease, thyroid disorder, and fragility fracture.OBJECTIVE The IKBKE has been proven to be associated with systemic lupus erythematosus (SLE) in a genome-wide association study (GWAS) conducted by our group. The objective of the recent study is to investigate the contribution of IKBKE functional variants (rs2297550) to SLE. METHODS We detected the regulatory effect of rs2297550 on IKBKE expression by expression quantitative trait loci (eQTL) study. Then, we investigated the differences of IKBKE mRNA expression levels in peripheral blood mononuclear cells (PBMCs) between 135 SLE patients and 130 healthy controls using quantitative real-time PCR (qRT-PCR). We further analyzed the association of SLE clinical characteristics with IKBKE mRNA expression and rs2297550 polymorphisms. RESULTS The results of eQTL indicated the genotype "GG" of single-nucleotide polymorphism (SNP) rs2297550 was associated with lower expression levels of IKBKE (P = 0.022) in normal controls. Compared with the healthy control group, the expression levels of IKBKE mRNA in patients with SLE were significantly decreased (P = 2.
