AbstractJoubert syndrome (JS) is a rare congenital, autosomal recessive disorder characterized by a distinctive brain malformation, developmental delay, ocular motor apraxia, breathing abnormalities, and high clinical and genetic heterogeneity. We are reporting three siblings with JS from consanguineous parents in Syria. Two of them had the same homozygous c.2172delA (p.Trp725Glyfs*) AHI1 mutation and the third was diagnosed prenatally with magnetic resonance imaging. This pathogenic variant is very rare and described in only a few cases in the literature. Multinational collaboration could be of benefit for the patients from undeveloped, low-income countries that have a low-quality health care system, especially for the diagnosis of rare diseases.

Election Results

Akin to the previous, 2014 event, with no data on voter ethnicity, no exit polls, and few post-election analyses, the 2018 Fiji election results remain something of a mystery despite the fact that there had been a significant swing in voting in favour of Opposition political parties. There have been several studies about the election results, but most of them have been done without much quantitative analyses. This study examines voting patterns of Fiji’s 2018 election by provinces, and rural-urban localities, as well as by candidates, and also compares the 2018 and 2014 elections by spending a substantial time classifying officially released data by polling stations and individual candidates. Some of the data are then further aggregated according to the political parties to which those candidates belonged. The current electoral system in Fiji is a version of a proportional system, but its use is rare and this study will provide an interesting case study of the Open List Proportional System. At the end of the analyses, this study considers possible reasons for the swing in favour of the Opposition.

AbstractThe paper analyzes the transformation of identity politics of Kharkiv local authorities after the Euromaidan, or Revolution of Dignity, the annexation of Crimea, and the War in Donbass. Being the second largest city in Ukraine and becoming the frontline city in 2014, Kharkiv is an interesting case for research on how former pro-Russian local elites treat new policies of the central government in Kyiv, on whether earlier they tried to mobilize their electorate or to provoke political opponents with using soviet symbols, soviet memory, and copying Russian initiatives in the sphere of identity.To answer the research question of this article, an analysis of Kharkiv city and oblast programs and strategies and of communal media were made. Decommunisation, as one of the most important identity projects of Ukrainian central authorities after 2014, was analyzed through publications in Kharkiv’s city-owned media as well as reports from other scholars. Some conclusions are made from the analysis of these documents: Kharkiv development strategy until 2020, Complex program of cultural development in Kharkiv in 2011–2016 (and the same for 2017–2021), The regional program of military and patriotic training and participation of people in measures of defense work in 2015–2017, Program of supporting civil society in 2016–2020 in Kharkiv region and the city mayor’s orders about the celebration of Victory Day (9 May), the Day of the National Flag (23 August), the Day of the City (23 August) and Independence Day (24 August) in 2010–2015.

Hydroalkylation of unsaturated hydrocarbons with unstablized carbon nucleophiles is difficult and remains a major challenge. The disclosed examples so far mainly focused on the involvement of heteroatom and/or stabilized carbon nucleophiles as efficient reaction partners. Reported here is an unprecedented regioselective nickel-catalyzed hydroalkylation of 1,3-dienes with hydrazones, generated in situ from abundant aryl aldehydes and ketones and acted as both the sources of unstabilized carbanions and hydride. With this strategy, both terminal and sterically hindered internal dienes are hydroalkylated efficiently in a highly selective manner, thus providing a novel and reliable catalytic method to construct challenging C(sp3)-C(sp3) bonds.
