NAJFNR is dedicated to publishing innovative and high-quality papers providing a better understanding of the advances in nutrition fields as original research, review, short communication, correspondence, case reports, hypothesis formation, expert opinion, and commentaries. The primary purpose of NAJFNR is to act as a source of information usable by researchers and practitioners to increase their knowledge about nutrition and its development among developing countries and the international scientific community.

On behalf of the Board, I am delighted to announce the launch of the inaugural issue of the first journal dedicated to the North African countries and Mediterranean region "The North African Journal of Food and Nutrition Research (NAJFNR) ". A new open access and international peer-reviewed journal, which publishes original (not previously published) work of exceptional quality and interest and which intends to give a wide-ranging coverage of research, views, and reviews on nutrition and its effects in relation to human health and disease. The NAJFNR will include all nutrition field research in humans and various disease model organisms and will be of interest to the basic researcher as well as to physician scientists and clinicians.

This year will see some fundamental changes at the Annals – changes that are aimed at both enhancing and maintaining its appeal across the broad range of surgical specialties. In this respect, there have already been some important refinements to the structure of the Editorial board. The Annals will now have representatives on its panel from the diapason of subspecialties. It is hoped that this will ensure an equitable apportionment of high-quality original research, review articles and case reports from across the surgical spectrum. It represents the single most tangible adjustment to the structure of the Annals in a generation and one of which I am sure Sir Cecil Wakeley would have approved. I would like to take this opportunity to formally welcome our new board members and invite them to join with our other long-term stalwarts into what is a uniquely collegiate editorial team. As many of our fellows and members will already be aware, there has been a significant shift made over the last few months in the handling of research contributions to the Annals. In recent weeks we have completed the transition to our new submissions portal and it is encouraging that reviewers and authors alike have commended it in equal measure. While we are sadly not in a position to accept much of the material submitted to the journal (we currently accept only one tenth of all the articles subjected to peer review) we can at least aim to improve and enhance the experience for all those involved. In many ways this digital migration is a precursor to a number of innovations that will fundamentally transform the way in which we produce the Annals, the most significant of which is the launch of our new digital platform this month. These innovations signal a gradual move away from the printed version as the principal conduit by which the Annals is distributed. Inevitably, there will be those who will lament the passing of this hitherto more familiar and tactile media and so measures are in hand to allow for a more limited production of a paper version of the Annals for RCS fellows and members who continue to elect to receive their Annals in the traditional format. Medical colleges around the world are currently undergoing similar deliberations and for some a digital version may represent the only opportunity to maintain editorial independence – unhindered by the implications of a commercial publishing partner. It is however hoped that for the vast majority of fellows and members, the new and enhanced digital platform will offer significant advantages such that the digital version becomes the de facto medium of choice. Matt Whitaker and the team at the Annals should be congratulated for their sterling efforts in making this transition. The new site, now live at http://publishing.rcseng.ac.uk , will enhance the experience of finding, accessing, reading, citing, sharing and saving articles from the Annals, Bulletin and FDJ. Sign-on will be much easier; page load times quicker and the search engine more powerful and intuitive. The new platform boasts improved functionality, full in-page article text and multi-media, citation tracking, reference generators and advanced social media integration. We are simultaneously launching a new video library where we will be hosting our technical videos. It will, I am certain, become a huge resource for our surgical fraternity. Our new platform will be followed later this year by the inevitable and ubiquitous app, which will allow readers to download issues of the Annals and read them offline and at leisure on whatever their tablet of choice might be. It is my belief that these and forthcoming changes herald the transformation of the Annals into a truly modern journal with all the digital services that authors and readers now rightly expect from their RCS publication.

The seeds of Ammodaucus leucotrichus Cosson and Durieu have been used in the North African Sahara as a traditional medicine to treat diabetes. The present study investigates the antidiabetic, antihyperglycemic, and anti-inflammatory properties of the defatted hydroethanolic extract of Ammodaucus leucotrichus (DHEAM). The antidiabetic and the antihyperglycemic studies were assessed on alloxan-induced diabetic with orally administered doses of DHEAM (100 and 200 mg/kg). At the same time, its anti-inflammatory propriety was evaluated by measuring edema development in the Wistar rats paw induced with carrageenan. Treatment of diabetic mice with DHEAM for four weeks managed their high fasting blood glucose levels, improved their overall health, and also revealed an excellent antihyperglycemic activity. Following the anti-inflammatory results, DHEAM exhibited a perfect activity. HPLC results revealed the presence of seven molecules (chlorogenic acid, 3-p-coumaroylquinic acid, gallic acid, ferulic acid, myricetin, quercetin, luteolin). This work indicates that the DHEAM has an important antidiabetic, antihyperglycemic, and anti-inflammatory effect that can be well established as a phytomedicine to treat diabetes.

Acephalic spermatozoa syndrome (ASS) is a rare but extremely severe type of teratozoospermia, defined by the presence of a majority of headless flagella and a minority of tail-less sperm heads in the ejaculate. Like the other severe monomorphic teratozoospermias, ASS has a strong genetic basis and is most often caused by bi-allelic variants in SUN5 (Sad1 and UNC84 domain-containing 5). Using whole exome sequencing (WES), we investigated a cohort of nine infertile subjects displaying ASS. These subjects were recruited in three centers located in France and Tunisia, but all originated from North Africa. Sperm from subjects carrying candidate genetic variants were subjected to immunofluorescence analysis and transmission electron microscopy. Moreover, fluorescent in situ hybridization (FISH) was performed on sperm nuclei to assess their chromosomal content. Variant filtering permitted us to identify the same SUN5 homozygous frameshift variant (c.211+1_211+2dup) in 7/9 individuals (78%). SUN5 encodes a protein localized on the posterior part of the nuclear envelope that is necessary for the attachment of the tail to the sperm head. Immunofluorescence assays performed on sperm cells from three mutated subjects revealed a total absence of SUN5, thus demonstrating the deleterious impact of the identified variant on protein expression. Transmission electron microscopy showed a conserved flagellar structure and a slightly decondensed chromatin. FISH did not highlight a higher rate of chromosome aneuploidy in spermatozoa from SUN5 patients compared to controls, indicating that intra-cytoplasmic sperm injection (ICSI) can be proposed for patients carrying the c.211+1_211+2dup variant. These results suggest that the identified SUN5 variant is the main cause of ASS in the North African population. Consequently, a simple and inexpensive genotyping of the 211+1_211+2dup variant could be beneficial for affected men of North African origin before resorting to more exhaustive genetic analyses.
