THC: moderation during implantation

New extraction method of THC and its metabolites, 11-OH-THC and THC-COOH, in plasma

Objectives: A liquid/liquid extraction technique on solid support of Δ9-tetradydrocannabinol (THC), 11-hydroxy-Δ9-tetradydrocannabinol (11-OH-THC) and 11-nor-Δ9-tetradydrocannabinol-9-carboxylic acid (THCCOOH) in plasma was developed in order to be assayed by high-performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS). Methods: The samples were extracted by liquid/liquid ex...

Ultrastructural Modifications of Human Endometrium during the Window of Implantation

The endometrium is a highly dynamic tissue empowered with the capacity to undergo cyclic dramatic changes in response to ovarian steroid hormones, ultimately aiming to create a window of receptivity for blastocyst implantation. Intensive research has been performed to understand and establish morphological and molecular correlates of embryo implantation. However, it still remains a biological m...

Dial a feeling: Detecting moderation of affect decline during ostracism.

Ostracism, being excluded and ignored, is a common and painful experience. Previous research has found ostracism's immediate effects robust to moderation by individual differences. However, this could be the result of using retrospective measures taken after the ostracism occurs, rather than assessing the effects of ostracism throughout the episode. Participants completed measures of loneliness...

Moderation of Oxidative Stress during Experimental Small Bowel Autotransplantation

Venous spasm during pacemaker implantation.

A 75-years-old female presented with dyspnea and syncope. Electrocardiogram revealed atrial fibrillation and complete atrioventricular block. She was therefore listed for pacemaker implantation on the next day. Initial attempt at venous access was left axillary vein. A venogram showed good venous anatomy (Fig. 1a). Several attempts to puncture axillary vein were made. However, there was no good...
