La « bête noire » de Françoise Aubin. Vicissitudes d’une enquête sur les techniques laitières mongoles
Authors: Hille Marie-Paule , Ruhlmann Sandrine 
Published: December 2022

À la disparition de notre collègue Françoise Aubin (1932-2017), nous avons étudié un de ses dossiers de recherche, constitué de trois boîtes « lait I », « lait II », « lait III », trouvées dans sa bibliothèque scientifique personnelle. Naviguant dans les méandres d’une recherche sur la technologie laitière industrielle mongole émergente en contexte communiste, nous montrons comment Françoise Aubin et son collègue technologue et microbiologiste de l’INRA Jean-Pierre Accolas (1936-2001) se sont heurtés à une énigme scientifique qualifiée de « bête noire », dont nous reconstituons un historique possible. Épluchant le contenu du dossier et examinant des documents clés, notre démarche consiste à traquer cette « bête » pour révéler l’enchevêtrement d’incertitudes, de problèmes de traduction et de contraintes d’accès au terrain durant la période communiste.
Fonctions et symbolismes des représentations écrites en contexte bouddhique et chamanique (Mongolie-Intérieure)
Authors: Dumont Aurore 
Published: December 2022

Cet article explore les fonctions et les symbolismes de différents types de représentations écrites produites en contexte bouddhique et chamanique dans la région autonome de Mongolie-Intérieure en République populaire de Chine. Il s’agira tout d’abord de comprendre comment ces représentations écrites, qui ont été choisies ou imposées, sont créées et interprétées par les populations locales. Nous examinerons ensuite la manière dont elles sont déployées et manipulées par les spécialistes religieux et les participants en contexte rituel, notamment lors des rituels aux oboo et des « trois jeux virils » (naadam). Nous mettrons en évidence la manière dont ces artéfacts écrits participent d’un double processus de légitimation des spécialistes rituels et de transmission des « traditions » autochtones. Nous montrerons également que, en s’insérant dans un schéma de coordination impliquant notamment les humains et les esprits, ces écrits favorisent l’obtention d’une efficacité rituelle recherchée par les populations locales.
Feuilles volantes et tapis talismaniques dans les rituels d’Ak Jaŋ (République de l’Altaï, Fédération de Russie)
Authors: Jacquemoud Clément 
Published: December 2022

Dans la République de l’Altaï (Sibérie du Sud, Fédération de Russie), de nombreux autochtones sont adeptes d’Ak Jaŋ (la « Voie blanche »), un mouvement religieux local revitalisant les pratiques et les représentations du bourkhanisme, un millénarisme messianique présoviétique. Durant leurs rituels saisonniers, les adeptes emploient des tapis de feutre dont l’analyse des figurations qui y sont brodées constitue le sujet de cet article. L’idée avancée est que ces broderies, confectionnées par les adeptes féminines du mouvement selon des directives transmises par l’entité suprême Altaj Kudaj (le « Dieu Altaï »), agissent comme des talismans protecteurs du territoire face aux enjeux socioéconomiques et écologiques dont l’Altaï contemporain fait l’objet. Pour appuyer cette hypothèse, l’étude met en rapport les figurations brodées avec les « informations » que certaines femmes « médiums » au sein d’Ak Jaŋ reçoivent de la part des esprits, qu’elles diffusent ensuite dans et par-delà le mouvement religieux. L’article explore également comment ces médiums, via leurs expériences visionnaires, voient leur rôle religieux prendre une dimension sociale et politique inédite.
Conceptualiser l’éducation relative au changement climatique : les enjeux de la filière nucléaire
Authors: Laberge Yves 
Published: December 2022

Cet article se subdivise en trois parties. Nous esquisserons d’abord une définition encore provisoire de l’éducation au changement climatique. Nous discuterons ensuite des stratégies récentes de légitimation (réhabilitation, revalorisation) de l’industrie nucléaire face aux menaces causées par les changements climatiques. En troisième partie, nous apporterons quelques arguments critiques face à la prolifération du nucléaire, afin de détecter et déconstruire l’apologie (directe ou indirecte) de cette filière. Le but de cet article est de montrer la difficulté pour les éducateurs, les activistes, les jeunes - mais aussi pour les citoyens ordinaires préoccupés par l’avenir de la planète - d’appréhender l’éducation relative au changement climatique dans un contexte où beaucoup de gouvernants, de décideurs, d’experts, mais également d’éducateurs et une bonne partie de l’opinion publique doivent sans cesse soupeser l’impact réel des différentes mesures pouvant contrer le changement climatique. D’une manière habile et souvent persuasive, la filière nucléaire tente par diverses stratégies de s’imposer et de se (re)légitimer, incessamment et subtilement, sous le prétexte très contestable de ne pas produire de gaz à effet de serre, en donc tentant de faire croire - sur des bases discutables - qu’elle serait une « énergie propre ». L’article conclut que les éducateurs doivent non seulement demeurer vigilants et bien armés face aux stratégies insidieuses de la filière nucléaire, mais qu’ils doivent rester attentifs et critiques devant toutes les sources d’information scientifique mises à la disposition des élèves et des étudiants à propos des changements climatiques et aussi en matière de risques nucléaires.

Published: December 2022

Background and purpose:Although some proposed mechanisms responsible for tamoxifen resistance have already been present, further study is needed to determine the mechanisms underlying tamoxifen resistance more clearly. The critical role of Notch signaling has been described in promoting resistance in therapeutics, but there is little information about its role in tamoxifen resistance progression.Experimental approach:In the present study, the expression of Notch pathway genes, includingNotch4, nicastrinand the Notch downstream targetHes1was evaluated using quantitative RT-PCR in 36 tamoxifen-resistant (TAM-R) and 36 tamoxifen-sensitive (TAM-S) patients. Expression data were correlated with the clinical outcome and survival of patients.Findings/Results:mRNA levels ofNotch4(fold change = 2.7),nicastrin(fold change = 6.71), andHes1(fold change= 7.07) were significantly higher in TAM-R breast carcinoma patients compared to sensitive cases. We confirmed all these genes were co-expressed. Hence, it seems that Notch signaling is involved in tamoxifen resistance in our TAM-R patients. Obtained results showed thatHes1, nicastrin,andNotch4mRNA upregulation was correlated with the N stage. The extracapsular nodal extension was associated withnicastrinandNotch4overexpression. Moreover,nicastrinoverexpression was correlated with perineural invasion.Hes1upregulation was also associated with nipple involvement. Finally, the Cox regression proportional hazard test revealed that overexpression ofnicastrinwas an independent worse survival factor.Conclusion and implications:Presumably, upregulation of the Notch pathway may be involved in tamoxifen resistance in breast cancer patients.

Published: December 2022

Background/aim
Phonetics is an important function of the oral cavity that can be affected by partial or total loss of teeth. This study aimed to examine the influence of the partial denture’s construction technique (conventional and CAD/CAM) on speech quality through acoustic analysis of sound production of letters S, Sh, T, and D using sound analysis software.

Patients and methods
The study was conducted on 20 patients aged from 25 to 50 years having maxillary anterior teeth loss (Kennedy class IV classification). The patients were randomly categorized into two groups: group I received conventional removable partial dentures (RPDs), while group II received CAD/CAM RPDs. Acoustic speech analysis of the selected letters (S, Sh, T, and D) of the delivered RPDs was assessed and analyzed using ANSYS sound software and SIL speech Analyzer, 1 and 3 months after denture insertion. Statistical analysis was carried out using paired t test and independent t test.

Results
Group II showed significant difference (P<0.05) in the acoustic pronunciation of the selected letters, in the follow-up period from denture insertion to 1 month after, while for the follow-up period from denture insertion to 3 months there was insignificant difference (P>0.05) in the acoustic pronunciation of the S, Sh, and T sound compared to group I. Within group I and group II separately, they revealed significant difference for all the measured parameters except for VOT/(D) which was insignificantly different.

Conclusion
RPDs constructed by CAD/CAM technology have a more precise fit of the chrome–cobalt framework with a high quality of sound production even at the time of denture insertion.

Published: December 2022

Background/aim
The diagnosis of breast cancer depends mainly on mammography or histopathology, but recently, salivary biomarkers have proved to be a promising tool as a noninvasive diagnostic technique. Cancer antigen (CA)15-3 is a widely used prognostic serum breast cancer biomarker. Cytokines have been used as biomarkers in research for prognosis and have been related with symptoms and adverse outcomes in breast cancer. The present study aimed to assess the accuracy of CA15-3 and interleukin (IL)-1β expression in saliva versus serum of patients with breast cancer.

Patients and methods
This study enrolled 26 patients with breast cancer from El Demerdash Hospital, Cairo, Egypt. In addition, 16 healthy individuals served as a control group. Saliva and blood samples were collected from all participants. Saliva was collected in the morning at least 2 h after the last intake of food. CA15-3 and IL-1β expressions were measured in saliva and serum using the enzyme-linked immunosorbent assay technique.

Results
The present results indicated that there were significant differences (P<0.05) in the expression of CA15-3 between patients with breast cancer and healthy individuals. Moreover, a significant difference was found in the expression of IL-1β between patients with breast cancer and healthy individuals in both serum and saliva samples. There were higher expressions (P<0.05) of CA15-3 in saliva than in serum as well as a higher expression (P<0.05) of IL-1β in saliva than in serum.

Conclusion
Saliva can be used as a diagnostic tool in early detection of breast cancer with high accuracy in comparison with serum.
Vitamin D receptor gene polymorphisms (BsmI and FokI) and serum levels of 25-hydroxyvitamin D in Egyptian patients with type 2 diabetes and their association with atherosclerosis
Authors: Gomaa Salwa H. , Shehata Gihan M. , Ooda Said A. , Eldeeb Mona K. 
Published: December 2022

Background/aim
A large number of individuals with type 2 diabetes mellitus (T2DM) die owing to atherosclerotic cardiovascular diseases (CVD). The role of vitamin D deficiency and vitamin D receptor (VDR) gene polymorphisms in the development of T2DM-related CVD has yet to be established. We aimed to determine the association of 25(OH) vitamin D and VDR gene (BsmI and FokI) polymorphisms with T2DM and its accompanying atherosclerosis.

Patients and methods
This study enrolled 45 male patients with T2DM and manifested CVD who were admitted to the Department of Internal Medicine of Medical Research Institute Hospital, Alexandria University, Egypt, in addition to 45 healthy male volunteers. 25(OH) vitamin D was measured in all cases. Carotid intima-medial thickness was measured, in addition to analysis of VDR gene (BsmI and FokI) polymorphisms using PCR and restriction fragment length polymorphism for all studied participants.

Results
Significantly lower vitamin D levels were observed in the diabetic atherosclerotic group than controls. The minor allele f of the FokI polymorphism and the minor allele b of BsmI polymorphism were associated with a higher risk of coronary artery disease in patients with T2DM, with an odds ratio of 12.750 (P=0.002) and 6.122 (1.202–30.078), respectively. FF genotype had significantly lower levels of total cholesterol and low-density lipoprotein cholesterol than Ff and ff genotypes (P=0.01 and 0.04, respectively).

Conclusion
Presence of the f allele of FokI as well as the b allele of BsmI polymorphisms of the VDR gene could increase the risk of atherosclerosis in Egyptian patients with T2DM, through influencing lipid metabolism. Vitamin D deficiency might contribute to increased risk of atherosclerosis in T2DM independent of the variants of VDR gene.
Establishment and implementation of an improvement plan using Lean Six Sigma methodology to minimize variation in ordering laboratory tests
Authors: Gomaa Salwa H. , Abaza Mona M. , Rashwan Reham M. , Dowidar Nabil L. , Elgaddar Ola H. 
Published: December 2022

Background/aim
Ordering laboratory (laboratory) tests by physicians is a part of the pre-preanalytical laboratory phase, which is a high error-prone process. Many of the laboratory tests ordered are unnecessary, where excess ordering represents as much as 25–40% of all ordered tests. The present study aimed at establishing and implementing a quality improvement project to avoid misutilization of laboratory tests using the Lean Six Sigma (LSS) methodology that could help to minimize variation in the laboratory requests ordered by clinicians.

Materials and methods
LSS approach methodology with its five phases, namely, define, measure, analyze, improve, and control (DMAIC), was applied to define and solve the problem of ordering of inappropriate laboratory tests. Sigma levels of the ordering process of selected laboratory tests were measured before and after implementation of the selected solutions. The stability and capability of the ordering process were retested after implementing the project.

Results
The sigma level of alanine aminotransferase/aspartate aminotransferase tests ordering process has been improved to 1.2 sigma, which represented 45% improvement. The sigma level of urea and creatinine ordering has been improved to 2.16 sigma, which represented 43.1% improvement, saving about 14 520 LE per year.

Conclusion
Successful implementation of LSS significantly improved laboratory test ordering. Simple modification in the laboratory request form could be an important source of improvement and a cost reduction tool in the pre-preanalytical laboratory phase. LSS is an evidence-based powerful tool that could improve the health care sector in general and the clinical laboratories in particular.
