CFD-based design optimization of a 5 kW ducted hydrokinetic turbine with practical constraints [PDF]

open access: yesarXiv
Ducted hydrokinetic turbines enhance energy-harvesting efficiency by better conditioning the flow to the blades, which may yield higher power output than conventional freestream turbines for the same reference area. In this work, we present a ducted hydrokinetic turbine design obtained by simultaneously optimizing the duct, blade, and hub geometries ...

Tristetraprolin affects invasion‐associated genes expression and cell motility in triple‐negative breast cancer model

open access: yesCytoskeleton, EarlyView.
Abstract Tristetraprolin (TTP) is an RNA‐binding protein that negatively regulates its target mRNAs and has been shown to inhibit tumor progression and invasion. Tumor invasion requires precise regulation of cytoskeletal components, and dysregulation of cytoskeleton‐associated genes can significantly alter cell motility and invasive capability. Several

Different clinical and genetic features of Alagille patients with progressive disease versus a jaundice‐free course

open access: yesJGH Open, Volume 6, Issue 12, Page 839-845, December 2022., 2022
This study highlighted the different disease courses of Alagille syndrome patients with progressive disease (PD) or the jaundice‐free (JF) courses based on clinical follow‐up. Patients in the JF group had a favorable outcome and longer native liver survival than the PD group.

Obliterative portal venopathy: A neglected and probably misdiagnosed disease with peculiar etiology in South America

open access: yesJGH Open, Volume 6, Issue 12, Page 904-909, December 2022., 2022
Classically described in the group of non‐cirrhotic portal hypertension, obliterative portal venopathy (OPV) causes are still unknown. Our aim is to describe the characteristics of 43 OPV patients and potential risk factors. Clinically significant portal hypertension was found in 28% of cases. The most frequent indication for liver biopsy was elevation

Night‐Time Chronotherapy with Methylprednisolone Prevents an Acute Rejection in Pediatric Patients with Liver Transplantation: A Randomized Clinical Trial

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Concept of methylprednisolone chronotherapy to prevent acute rejections. While endogenous cortisol secretion rises in the early morning, the number of lymphocytes in the blood is higher at night, thus exhibiting an antiphase pattern to cortisol secretion. Therefore, compared with the daytime, the infiltration of lymphocytes into immune‐reactive tissues
