Our findings suggest that these lesions in the noncancerous stomach might be associated with vonoprazan treatment. We investigated the two cases endoscopically and histologically, and we report our findings with a literature review.Most cases of Dieulafoy's lesion, a rare cause of upper gastrointestinal bleeding, occur in the upper gastric corpus, usually with no edematous bulging or fold convergence around the mucosal defect. This report describes a case of Dieulafoy's lesion with subepithelial lesion (SEL)-like morphology. Endoscopic treatment by hemoclipping was difficult. Because of repeated bleeding, abdominal dynamic contrast computed tomography (CT) was conducted. Results showed a large caliber, tortuous artery branching directly from the celiac artery and feeding into the gastric wall of the gastric fundus. Rupture of this vessel in the submucosa was thought to be responsible for the SEL-like morphology. All findings indicated endoscopic treatment from the gastric mucosal side was too difficult. Therefore, we treated the lesion using interventional radiology (IR) technique of vascular embolization. If an SEL-like Dieulafoy's lesion cannot be treated by endoscopic hemostasis, then IR might be necessary to treat the vascular anomaly.Lenvatinib is a standard molecular targeted agent for the first-line treatment of unresectable hepatocellular carcinoma. Here, we report a case of colitis induced by Lenvatinib treatment in a patient with hepatocellular carcinoma. A 78-year-old man previously treated with Lenvatinib for unresectable hepatocellular carcinoma was admitted to our hospital complaining of right lateral abdominal pain without diarrhea. Our endoscopic findings showed multiple ulcers and erosions on his ascending colon, and he was diagnosed with colitis induced by Lenvatinib treatment. After the discontinuation of Lenvatinib, his colitis improved, and he resumed Lenvatinib at a lower dose. Colitis is a rare adverse event of Lenvatinib, and this is the first detailed report of colitis induced by Lenvatinib with endoscopic findings.

The aims of this study were to characterize the multiple-dose pharmacokinetics (PK) of ozanimod's major active metabolites (CC112273 and CC1084037) and to evaluate the pharmacodynamic and PK interactions with pseudoephedrine (PSE).

In this phase1, single-center, randomized, double-blind, placebo-controlled study, 56 healthy adult subjects were randomized to receive either placebo or ozanimod once daily for 30days (0.23mg on days1-4, 0.46mg on days5-7, 0.92mg on days8-10, and 1.84mg on days11-30). On day30, a single oral dose of PSE 60mg was co-administered with placebo or ozanimod. Maximum time-matched change in systolic blood pressure (SBP) from baseline (day29) following PSE administration on day30 was calculated. Plasma PK parameters for ozanimod, CC112273, CC1084037, and PSE were estimated using noncompartmental methods.

Fifty-two subjects (92.9%) completed the study. Following multiple dosing, approximately 94% of circulating total active drug exposure was represented by ozanimod (6%), CC112273 (73%), and CC1084037 (15%). see more Exposures of CC112273 and CC1084037 were highly correlated. Mean maximum time-matched change from baseline for SBP was not significantly different between ozanimod + PSE and placebo + PSE. Ozanimod also had no effect on the PK of PSE. Co-administration of ozanimod with a single dose of PSE in healthy subjects was generally well tolerated. While CC112273 and CC1084037 selectively inhibited monoamine oxidase (MAO)-B in vitro, both active metabolites do not inhibit platelet MAO-B activity in vivo.

Concomitant administration of ozanimod with PSE, a sympathomimetic agent, did not potentiate the effects on blood pressure.

NCT03644576.Environmental pollutants with endocrine-disrupting effect are of global importance due to their contribution to the aethiologies of variety of complex diseases. These lipophilic pollutants are persistent in the environment and able to bioaccummulate in nontarget organisms. BPA, DEHP and PCB118 (dioxin-like PCB) are associated with endocrine disruption effects, while information on their effects on aquatic invertebrates are limited. In the current study, the effects of these compounds, which are ubiqutous and present at low concentrations in the environment, are studied in the primary hepatopancreas, muscle, gill, intestine and gonadal cultures of narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823), a widely distributed freshwater crayfish in Turkey with high economic importance. IC50 values following MTT assay ranged 0.27-12.61 nM; when compared with other tissues, the gonads were more affected with lower IC50 values. PCB118 induced higher cytotoxicity, while DEHP was the least toxic compound. This is the first study on the primary culture of A. leptodactylus¸ and the toxic effects of these compounds in this organism providing mechanistic insights on the responses and detoxification capacity of the organs. This study provides basis to unravel the mechanism of action of the tested EDCs in crayfish and improvement of cell culture conditions for ecotoxicity and screening assays.Sickle cell disease is a group of diseases inherited through the gene and it affects the haemoglobin in the red blood cell. This study investigated the methanol seed extract of Buchholzia coriacea for possible in vitro anti-sickling effects and also determined the effect of Mucuna pruriens seed extract on the solubility and oxygen-binding rate of sickle cell haemoglobin. Sickle cell blood was collected from sickle cell disease patients with subsequent addition of 2% sodium metabisulphite to cause more sickling. Varying concentrations of the seed extracts (50%, 25%, 12.5% and 6.25%) were added to the pre-treated blood for these in vitro assays. The results showed that the extract of Buchholzia coriacea significantly (P less then 0.05) inhibited sickling at all concentrations with the highest percentage inhibition of 73.3 ± 5.8, reversed sickled erythrocytes at all concentrations with the highest percentage reversal of 83.3 ± 5.8 and significantly (P less then 0.05) inhibited polymerisation at all concentrations used in comparison to the parallel control.
