The Structural Effects of Modality on the Rise of Symbolic Language: A Rebuttal of Evolutionary Accounts and a Laboratory Demonstration.

Front Psychol 2018 28;9:2300. Epub 2018 Nov 28.

Laboratoire de Sciences Phonétiques, Département de Linguistique, Université de Montréal, Montreal, QC, Canada.

Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. Read More

Managing stake and accountability in Prime Ministers' accounts of the "refugee crisis": A longitudinal analysis.

J Community Appl Soc Psychol 2018 Nov-Dec;28(6):406-429. Epub 2018 Nov 8.

Department of Social Research University of Helsinki Helsinki Finland.

Taking a (critical) discursive psychological approach, the present study explores the identity management of the Finnish and Swedish Prime Ministers (PM) in relation to the "refugee crisis" and their countries' asylum policies. By taking a longitudinal approach and analysing the PMs' accounts of the "refugee crisis" from 1-year period, we focused on the ways rhetorical devices related to ethos, logos, and pathos were used to manage the issues of stake and accountability, as well as on the ways in which categories were worked up to serve particular functions. Our comparative analysis demonstrated significant similarities in the Finnish and Swedish PMs' talk, especially with regard to the transfer from a discourse of pathos and ethos, describing refugees in terms of individualism and humaneness, to a discourse of logos, emphasizing rationality, justifying sharpened immigration policies, and homogenizing refugees.

Natl J Maxillofac Surg 2018 Jul-Dec;9(2):117-122

Department of Periodontology, Faculty of Dental Sciences, King George's Medical University, Lucknow, Uttar Pradesh, India.

Transgingival (flapless) implant placement procedure is a minimally invasive surgical technique in which implant is placed without reflecting mucoperiosteal flap and hence the blood supply of bone is not hampered which is advantageous in many ways. To compare the outcomes of various implant placement techniques, an electronic database of various journals from January 1990 to March 2017 were analyzed and only human clinical trials with 6 months follow-up and at least five implants in each group were reviewed. The present literature review focuses on the comparative aspects of flapped versus flapless implants in terms of their survival, marginal bone loss, soft-tissue parameters, and patient-centered outcomes.

Flightless birds are not neuroanatomical analogs of non-avian dinosaurs.

BMC Evol Biol 2018 Dec 13;18(1):190. Epub 2018 Dec 13.

Division of Paleontology, American Museum of Natural History, New York, NY, 10024, USA.

Background: In comparative neurobiology, major transitions in behavior are thought to be associated with proportional size changes in brain regions. Bird-line theropod dinosaurs underwent a drastic locomotory shift from terrestrial to volant forms, accompanied by a suite of well-documented postcranial adaptations. To elucidate the potential impact of this locomotor shift on neuroanatomy, we first tested for a correlation between loss of flight in extant birds and whether the brain morphology of these birds resembles that of their flightless, non-avian dinosaurian ancestors.

Comparative evaluation of mesenchymal stromal cells from umbilical cord and amniotic membrane in xeno-free conditions.

BMC Cell Biol 2018 Dec 13;19(1):27. Epub 2018 Dec 13.

Department of Rheumatology, the First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, Shaanxi Pvovince, China.

Background: Within the past years, umbilical cord (UC) and amniotic membrane (AM) expanded in human platelet lysate (PL) have been found to become increasingly candidate of mesenchymal stromal cells (MSCs) in preclinical and clinical studies. Different sources of MSCs have different properties, and lead to different therapeutic applications. However, the similarity and differences between the AMMSCs and UCMSCs in PL remain unclear.

Platelet-Rich Plasma Versus Hyaluronic Acid Injections for the Treatment of Knee Osteoarthritis: Results at 5 Years of a Double-Blind, Randomized Controlled Trial.

Am J Sports Med 2018 Dec 13:363546518814532. Epub 2018 Dec 13.

Applied and Translational Research Center, IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy.

Background:: Platelet-rich plasma (PRP) injections have been proposed as a new conservative option for knee degeneration to provide symptomatic relief and delay surgical intervention. Although the current literature provides some evidence on the benefits of this technique compared with viscosupplementation, no studies have been performed to compare their long-term effects.

Purpose:: To compare the long-term clinical outcomes provided by intra-articular injections of either PRP or hyaluronic acid (HA) to treat knee degenerative disease. Read More
