Accid Anal Prev 2021 Apr 10;155:106119. Epub 2021 Apr 10.

University of Naples Federico II, Department of Civil, Architectural and Environmental Engineering, Via Claudio 21, 80125, Naples, Italy. Electronic address:

The main objective of this paper was to analyse the roadway, environmental, and driver-related factors associated with an overrepresentation of frequency and severity of run-off-the-road (ROR) crashes. The data used in this study refer to the 6167 crashes occurred in the section Naples-Candela of A16 motorway, Italy in the period from 2001 to 2011. The analysis was carried out using the rule discovery technique due to its ability of extracting knowledge from large amounts of data previously unknown and indistinguishable by investigating patterns that occur together in a given event.

Interferon-γ-mediated gene expression in porcine alveolar macrophage; An in vitro model.

Q Liu H-Y Wang

Pol J Vet Sci 2021 Mar;24(1):135-143

Nanchong Key Laboratory of Disease Prevention, Control, and Detection in Livestock and Poultry, Nanchong Vocational and Technical College, Nanchong 637131, China.

Alveolar macrophages (AMs) are not only important immune cell of the host, but also important target cell of a variety of respiratory pathogens. They play an important role in defense against pathogen invasion and in maintaining tissue balance. Interferon (IFN)-γ is a well known multipotent cytokine that has antiviral and antibacterial immune activity and enhances antigen presentation. Read More

[Safety and efficiency of epithelium-off accelerated corneal cross-linking for progressive keratoconus in pediatric patients].

J Fr Ophtalmol 2021 Apr 9. Epub 2021 Apr 9.

Service d'ophtalmologie, Pavillon C, hôpital Edouard-Herriot, 5, place d'Arsonval, 69003 Lyon, France; Faculté de médecine Lyon Sud, Charles-Mérieux, rue du Grand-Revoyet, 69006 Oullins, France.

In adults, the management of keratoconus has evolved in recent years to achieve a well-codified treatment algorithm. The technique of cross-linking (CXL) has allowed us to stabilize the progression of keratoconus and has been largely developed. It is very effective, with few postoperative complications. Read More

CRISPR/Cas9-mediated mutagenesis reveals the roles of Calaxin in gastropod larval cilia.

Gene 2021 Apr 9:145640. Epub 2021 Apr 9.

Key Laboratory of Experimental Marine Biology, Institute of Oceanology, Chinese Academy of Sciences, 266071, Qingdao, China; Laboratory for Marine Biology and Biotechnology, Qingdao National Laboratory for Marine Science and Technology, 266000, Qingdao, China; University of Chinese Academy of Sciences, 100039, Beijing, China; Center for Ocean Mega-Science, Chinese Academy of Sciences, 7 Nanhai Road, 266071, Qingdao, China. Electronic address:

Obtaining detectable knockout phenotypes in the G0 generation is essential for gene function studies. Although CRISPR/Cas9-mediated gene editing has been employed to knock out molluscan genes, detectable phenotypes in the G0 generation have not been reported in these animals. In this study, we determined the knockout phenotype of a cilium-related gene, calaxin, using CRISPR/Cas9 technology in the gastropod mollusk Lottia goshimai. Read More

Comparison of Laparoscopic and Open Surgery in the Treatment of Renal Hydatid Cysts.

J Laparoendosc Adv Surg Tech A 2021 Apr 12. Epub 2021 Apr 12.

Department of Urology, Health Sciences University, Adana City Training and Research Hospital, Adana, Turkey.

To compare the efficacy, safety, and long-term results of laparoscopic and open approaches in patients undergoing surgery for renal hydatid cyst. The files of 36 patients who were surgically treated in our clinic and with diagnosis of renal cyst hydatid confirmed pathologically were reviewed. According to the surgical technique applied, the patients were divided into two groups as open (group 1) or laparoscopic (group 2) partial pericystectomy. Read More

Fabrication of three dimensional bioactive Sr substituted apatite scaffolds by gel-casting technique for hard tissue regeneration.

J Tissue Eng Regen Med 2021 Apr 11. Epub 2021 Apr 11.

Department of Nanoscience and Technology, Bharathiar University, Coimbatore, 641046, Tamil Nadu, India.

This study aimed to fabricate three-dimensional (3D) bioactive Sr substituted apatite (Sr-HAP) scaffolds prepared by gel-casting with polymer sponge infiltration technique. Three dimensional (3D) Sr-HAP scaffolds were prepared as engineering constructs with interconnected porous structure with a pore size of 200μm to 600μm ranging from a 10mm×10mm×6mm size was designed. The characterization of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and energy dispersion spectroscopy (EDS) was utilized in order to evaluate the crystalline phase, structure and morphology in the interconnected porous of the synthesized Sr-HAP scaffold.

A marginal liver graft with hyperbilirubinemia transplanted successfully by ischemia-free liver transplantation.

Ann Transl Med 2021 Mar;9(5):425

Organ Transplant Center, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.

The shortage of transplant organs remains a serious issue worldwide, and using liver grafts from extended criteria donors could expand the donor pool. Extended criteria donor liver allografts have a high chance of complications such as primary nonfunction, early allograft dysfunction, and ischemic-type biliary lesions. How to employ these extended criteria donors safely and effectively warrants further investigation. Read More
