Published: February 2022

BACKGROUND: Stunting is a condition where the body height is shorter than normal, unproportioned to the child age, caused by lack of nutrition and/or caused by repeated disease in a long time period since the development of fetus until the first two years of life. The University of Alabama at Birmingham Health System states that Calcium, Phosphorus, vitamin C and vitamin D intake are extremely important so that lack of those nutrient can prohibit body growth and tooth development and eruption. Tuah Negri Sub-district at Musi Rawas District, South Sumatra Province, Indonesia is one of sub-district in Indonesia with high prevalence of stunting event.
 
AIM: This research was performed to proof that there is an association between stunting and tooth eruption of primary school children at Tuah Negeri Sub-district, Musi Rawas District, South Sumatera Province, Indonesia.
 
METHODS: The research employed a quantitative research design with a cross-sectional analytical survey method. Nutritional status was examined anthropometrically to identify stunting event. Tooth examination was performed among 94 students of 5 purposively selective primary schools based on their high prevalence of stunting cases. The results were then put into the odontogram.
 
RESULTS: The results of the study showed that there were 31 children with stunting (33.0%), which is higher than the national data, and 21 of those with the stunting (67.7%) were identified as having delayed tooth eruption. Statistical examination using chi-squared test showed that the proportion of children with delayed tooth eruption was significantly higher among children with stunting compared to those without stunting, with p-value 0.034 and odds ratio (OR) 2.63 (95% C.I. = 1.7 – 6.5).
 
CONCLUSION: There is an association between stunting and tooth eruption of primary school children at Tuah Negeri Sub-district, Musi Rawas District, South Sumatera Province, Indonesia. Children with stunting have 2.63 times higher possibility to experience delayed tooth eruption compared with those without stunting

Bloom filter variants for multiple sets: a comparative assessment
Authors: Calderoni Luca , Maio Dario , Palmieri Paolo
Published: February 2022

In this paper we compare two probabilistic data structures for association queries derived from the well-known Bloom filter: the shifting Bloom filter (ShBF), and the spatial Bloom filter (SBF). With respect to the original data structure, both variants add the ability to store multiple subsets in the same filter, using different strategies. We analyse the performance of the two data structures with respect to false positive probability, and the inter-set error probability (the probability for an element in the set of being recognised as belonging to the wrong subset). As part of our analysis, we extended the functionality of the shifting Bloom filter, optimising the filter for any non-trivial number of subsets. We propose a new generalised ShBF definition with applications outside of our specific domain, and present new probability formulas. Results of the comparison show that the ShBF provides better space efficiency, but at a significantly higher computational cost than the SBF.

Published: February 2022

Cet article vise la compréhension des problématiques liées à l’École inclusive dans une perspective collaborative. Trois focus group ont été menés auprès d’enseignants, de personnels de vie scolaire et administratifs pour saisir l’expérience de l’inclusion de professionnels de collège, lors de l’implantation d’un dispositif Ulis. Nous adoptons une double approche théorique : clinique analytique des processus éducatifs et psychologie du développement. Les processus d’appropriation se traduisent d’une part par des controverses, de l’ambivalence, des paradoxes exprimés dans la dynamique interactive. Ces interrogations et réflexions relèvent de modifications des représentations et des pratiques professionnelles. Et d’autre part, une diversité de modalités d’appropriation subjective révèlent des positionnements singuliers liés à la rencontre et à l’accueil de l’autre différent, allant de mécanismes de défense à l’invention de nouvelles pratiques.
Les dispositifs Ulis. Enjeux d’un dispositif de transition
Authors: Midelet Julia
Published: February 2022

Les dispositifs Ulis, chargés d’accompagner les élèves reconnus en situation de handicap, ont pour mission d’aider les jeunes à préparer leur insertion sociale et professionnelle. Si cette préparation était réalisée dans des conditions ordinaires , elle se révélerait difficile voire impossible à réaliser tant les besoins et les compétences des jeunes suivis sont spécifiques. Aux attentes institutionnelles fortes se confrontent des réalités quotidiennes qui interrogent l’efficacité d’un tel dispositif. C’est ce que nous nous efforcerons d’approcher en explorant plus avant le concept de dispositif et ce qu’il implique du point de vue des différents acteurs que nous avons sollicités par le biais de questionnaires et d’entretiens semi-directifs.

Dans le cadre de notre thèse, notre objectif de recherche était de tenter d’identifier les compétences professionnelles (Altet, 1996 et 2009) acquises ou en cours d’acquisition des maîtres novices durant leur année de stagiarisation. Pour ce faire, nous avons observé six trinômes d’enseignants, composés chacun d’un maître expérimenté et de deux stagiaires, à travers trois dimensions organisatrices que sont la gestion de la tâche , du temps et des interactions maître-élèves . Nous avons repéré parmi les pratiques enseignantes des maîtres stagiaires, relatives à la résolution de problèmes au cycle 3, des organisateurs de pratiques typiques, ayant une influence sur les pratiques d’apprentissage des élèves (taux d’implication des élèves dans la tâche notamment). Ces organisateurs sont pour certains directement liés à la gestion de l’hétérogénéité de la classe.
Acceleration of the generalized FOM algorithm for computing PageRank
Authors: Jin Yu , Wen Chun , Shen Zhao-Li
Published: February 2022

In this paper, a generalized full orthogonalization method (GFOM) based on weighted inner products is discussed for computing PageRank. In order to improve convergence performance, the GFOM algorithm is accelerated by two cheap methods respectively, one is the power method and the other is the extrapolation method based on Ritz values. Such that two new algorithms called GFOM-Power and GFOM-Extrapolation are proposed for computing PageRank. Their implementations and convergence analyses are studied in detail. Numerical experiments are used to show the efficiency of our proposed algorithms.

In this article, a new two-parameter discrete power-Ailamujia (DsPA) distribution is derived using the survival discretization technique. Some key distributional properties and reliability measures are explored in closed forms, such as probability generating function, first four moments and mean residual life. The DsPA parameters are estimated using the maximum likelihood approach. The performance of this estimation method is assessed via a simulation study. The flexibility of the DsPA distribution is shown using three count datasets. The DsPA distribution provides a better fit than some recent discrete models such as the discrete Burr-Ⅻ, uniform Poisson–Ailamujia, Poisson, discrete-Pareto, discrete-Rayleigh, discrete inverse-Rayleigh, and discrete Burr–Hutke distributions.

Published: February 2022

There was a change in the implementation of education policies in the emergency period of the spread of the covid-19 virus, the learning process was carried out from home online using various learning resources. This condition triggers the emergence of behavioural problems and student competence in Indonesia. One of the distance learning media that was carried out during the pandemic was using the Learning Management System (LMS). Not only that, a policy evaluation needs to be carried out to evaluate the distance learning system that has been implemented in universities. This is because technology-based distance learning requires a different approach in terms of planning, implementation and evaluation. To increase the effectiveness of learning can use the assessment for learning (AfL) model. The learning process is also expected to be in accordance with learning that directs to have a computational thinking approach which is much needed considering that problem-solving skills are needed in solving everyday problems. Based on the results of data analysis with the 4D development model (define, design, develop, and disseminate), a learning management system based on assessment for learning to improve computational thinking abilities got an average score of 85.2, which means it can be implemented well.

Published: February 2022

Technological advancement in the recent decades enhanced the calibre of human life. Contemporary research in machine learning (ML) exhibits a mock-up to make decisions on its own and is applied in various fields including medical diagnosis, email filtering, banking, computer vision, financial marketing, image processing, cyber security. The systems inter-connected across the world via internet are attacked by hackers, and it is prevented by cyber security. The optimum solution for cyber-attacks is attained by collaborating ML techniques with cyber security and envisioned issues are designed by cyber machine learning models. In this chapter, an algorithm is proposed to defend data by encoding the text to an unintelligent text and decoding it to original text by applying graph labelling in cryptography. Symmetric key is designed based on the edge label of an odd-even congruence graph to achieve secured communication in CPS. In addition, a program is suggested using Python programming to attain cipher text and its converse.
A Cyber Physical System Framework for Industrial Predictive Maintenance Using Machine Learning
Authors: S. Sharanya
Published: February 2022

The rampant developments in the field of predictive analytics, artificial intelligence, big data, along with information and communication technologies have opened new ventures in cyber physical systems (CPS). The wide range of opportunities presented by CPS facilitated massive transformation of industrial processes that converged to building smart systems under the umbrella of Industry 4.0. The manufacturing and energy sector are now shifting their focus on predictive maintenance to pre plan their maintenance activities to reduce the downtime at optimized costs. This proactive maintenance planning involves the integration of multiple technologies like big data analytics, machine learning, and internet of things to build a complete, comprehensive framework that predicts the onset of failure from the early warning signs. The primal focus of this work is to develop a generic CPS framework for predictive maintenance (PdM) in industries from the condition monitored data.

The oncotherapeutic promise of IL-15, a potent immunostimulant, is limited by a short serum t1/2. The fusion protein N-803 is a chimeric IL-15 superagonist that has a >20-fold longer in vivo t1/2 versus IL-15. This phase 1 study characterized the pharmacokinetic (PK) profile and safety of N-803 after s.c. administration to healthy human volunteers. Volunteers received two doses of N-803, and after each dose, PK and safety were assessed for 9 d. The primary endpoint was the N-803 PK profile, the secondary endpoint was safety, and immune cell levels and immunogenicity were measures of interest. Serum N-803 concentrations peaked 4 h after administration and declined with a t1/2 of ∼20 h. N-803 did not cause treatment-emergent serious adverse events (AEs) or grade ≥3 AEs. Injection site reactions, chills, and pyrexia were the most common AEs. Administration of N-803 was well tolerated and accompanied by proliferation of NK cells and CD8+ T cells and sustained increases in the number of NK cells. Our results suggest that N-803 administration can potentiate antitumor immunity.
Reinnervation of Vastus lateralis is increased significantly in seniors (70-years old) with a lifelong history of high-level exercise (2013, revisited here in 2022)

In 2013 we presented results showing that at the histological level lifelong increased physical activity promotes reinnervation of muscle fibers in aging muscles. Indeed, in muscle biopsies from 70-year old men with a lifelong history of high-level physical activity, we observed a considerable increase in fiber-type groupings (F-TG), almost exclusively of the slow type. Slow-type transformation by denervation-reinnervation in senior sportsmen seems to fluctuate from those with scarce fiber-type transformation and groupings to almost fully transformed muscle, going through a process in which isolated fibers co-expressing fast and slow Myosin Heavy Chains (MHCs) seems to fill the gaps. Taken together, our results suggest that, beyond the direct effects of aging on the muscle fibers, changes occurring in skeletal muscle tissue appear to be largely, although not solely, a result of sparse denervation-reinnervation. The lifelong exercise allows the body to adapt to the consequences of the age-related denervation and to preserve muscle structure and function by saving otherwise lost muscle fibers through recruitment to different, mainly slow, motor units. These beneficial effects of high-level life-long exercise on motoneurons, specifically on the slow type motoneurones that are those with higher daily activity, and on muscle fibers, serve to maintain size, structure and function of muscles, delaying the functional decline and loss of independence that are commonly seen in late aging. Several studies of independent reserchers with independent analyses confirmed and cited our 2013 results. Thus, the results we presented in our paper in 2013 seem to have held up rather well.
BK Polyomavirus Hemorrhagic Cystitis in Hematopoietic Cell Transplant Recipients
Authors: Lionel Sharon Anbumalar , Abraham Aby , Mathews Vikram , Lakshmi Kavitha , Abraham Asha Mary , George Biju
Published: February 2022

Introduction:

BK polyomavirus-associated hemorrhagic cystitis (BKPyV-HC) is a well-recognized infective complication of hematopoietic cell transplant (HCT) with increased organ dysfunction and mortality. This study was performed to describe the local incidence, risk factors, and outcomes of BKPyV infection.

Methods:

This retrospective case–control study was conducted between 2007 and 2016 from a tertiary hospital in South India. We identified HCT recipients diagnosed with BKPyV-HC and compared them with recipients over the same period who did not develop BK virus infection matched for age, sex, diagnosis, and donor type. We collected data from central electronic medical records and databases maintained in the departments of hematology and virology.

Results:

Over the study period, 1276 transplants were performed, of which 262 patients (20.5%) developed HC and 105 (8.2%) were BKPyV-positive. Grade 3 HC was most commonly (57.1%) seen, and the median time to develop BKPyV-HC was 35 (range 0–858) days. Survival was significantly lower in the cases (42.9% vs. 61%, P < 0.05). On univariate analysis, the protective effect of nonmyeloablative conditioning (P = 0.04), residual disease at the time of transplant in malignant conditions (P = 0.001), lower CD34 dose (P = 0.006), presence of acute graft versus host disease (GVHD, P < 0.001), reactivation of cytomegalovirus infection (P < 0.001), and presence of bacterial urinary tract infection (UTI) (P < 0.001) were significant factors. Multivariate logistic regression confirmed the presence of acute GVHD (P = 0.041), bacterial UTI (P < 0.001), and residual disease (P = 0.009) at HCT as significant risk factors for BKPyV-HC.

Conclusions:

Our study affirms the homogeneity of BKPyV-HC disease in low- and middle-income HCT settings with prior reports and the need for therapeutic strategies to reduce its resultant mortality.
Assessment of Hepatitis B and Hepatitis C Status in Children with Chronic Kidney Disease
Authors: Ara Jannat
Published: February 2022

Background:

Children with chronic kidney disease (CKD) are immunocompromised and they are more prone to develop hepatitis B and hepatitis C virus infections.

Objective:

The aim of this study was to evaluate the status of hepatitis B and hepatitis C in children with CKD.

Study Design:

This was a cross-sectional study.

Study Setting and Period:

This study was conducted at the Department of Pediatrics Nephrology, Dhaka Shishu (Children) Hospital, from February 2019 to July 2019.

Study Population:

Children aged 6 months–18 years with the diagnosis of CKD participated in the study.

Materials and Methods:

A total of 35 purposively selected patients with CKD were enrolled. Thorough history, physical examination, and necessary investigations were done. CKD staging was done by using the revised Schwartz formula. All 35 patients were in CKD stages 3–5. They were divided into three groups: CKD stage 3–4; CKD stage 5 pre-hemodialysis (pre-HD); and CKD stage 5 maintenance HD. Then hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (anti-HCV), and hepatitis B surface antibody (anti-HBs) titer were assessed in all patients and compared between the groups. Analysis was done by the analysis of variance (ANOVA) and t test. A value of P < 0.05 was considered statistically significant.

Results:

The study revealed that all 35 patients were negative for HBsAg and anti-HCV. Anti-HBs antibody titer in 25.7% patients were 00 mIU/mL, in 40% patients <10 mIU/mL, in 20% patients 10–100 mIU/mL, and in 14.3% patients >100 mIU/mL. Majority (65.7%) of the patients had no protection (titer 0–<10 mIU/mL) against hepatitis B virus (HBV) infection and seen declining of anti-HBs antibody titer with increase of age in the study population. No significant difference of antibody titer was found in between gender, cause of CKD, different stages of CKD, and duration of the disease.

Conclusion:

In this study, all patients with CKD were negative for HBsAg and anti-HCV. Patients were negative for HBsAg. However, majority (65.7%) of patients show no protection against HBV infection.
A Lightweight Face Recognition Model based on MobileFaceNet for Limited Computation Environment
Authors: Xiao Jianyu , Jiang Guoli , Liu Huanhua
Published: February 2022

The face recognition method based on deep convolutional neural network is difficult to deploy in the embedding devices. In this work, we optimize the MobileFaceNet face recognition network MobileFaceNet so as to deploy it in embedding environment. Firstly, we reduce the model parameters by reducing the number of layers in MobileFaceNet. Then, the h-ReLU6 activation function is used to replace PReLU in the original model. Finally, the effective channel attention module efficient channel attention is introduced to obtain the importance of each feature channel by learning. After the optimization, the MobileFaceNet parameters are compressed to 3.4 MB,which is smaller than the original model (4.9 MB), and the mAPs reach 98.52%, 97.54% and 91.33% on the test sets of LFW, VGGFace2 and the self-built database, respectively, and the recognition time is about 85 ms/photo. It shows that the proposed method achieves a good balance between the model complexity and model performance.
Systoles and Lagrangians of random complex algebraic hypersurfaces
Authors: Gayet Damien
Published: February 2022

Let

n\geq 1

be an integer, and

\mathcal L \subset \mathbb{R}^n

be a compact smooth affine real hypersurface, not necessarily connected. We prove that there exist

c>0

and

d_0\geq 1

such that for any

d\geq d_0

, any smooth complex projective hypersurface

Z

in

\mathbb{C} P^n

of degree

d

contains at least

c\dim H_{*}(Z, \mathbb{R})

disjoint Lagrangian submanifolds diffeomorphic to

\mathcal L

, where

Z

is equipped with the restriction of the Fubini–Study symplectic form (Theorem 1.1). If moreover all connected components of

\mathcal L

have non-vanishing Euler characteristic, which implies that

n

is odd, the latter Lagrangian submanifolds form an independent family in

H_{n-1}(Z, \mathbb{R})

(Corollary 1.2). These deterministic results are consequences of a more precise probabilistic theorem (Theorem 1.23) inspired by a 2014 result by J.-Y. Welschinger and the author on random real algebraic geometry, together with quantitative Moser-type constructions (Theorem 3.4). For

n=2

, the method provides a uniform positive lower bound for the probability that a projective complex curve in

\mathbb{C} P^2

of given degree equipped with the restriction of the ambient metric has a systole of small size (Theorem 1.6), which is an analog of a similar bound for hyperbolic curves given by M. Mirzakhani (2013). In higher dimensions, we provide a similar result for the

(n-1)

-systole introduced by M. Berger (1972) (Corollary 1.14). Our results hold in the more general setting of vanishing loci of holomorphic sections of vector bundles of rank between 1 and

n

tensored by a large power of an ample line bundle over a projective complex

Пусть $\Gamma$ - дистанционно регулярный граф диаметра 3 с сильно регулярным графом $\Gamma_3$, где $\Gamma_3$ - граф, у которого множество вершин совпадает с множеством вершин графа $\Gamma$ и две вершины смежны тогда и только тогда, когда они находятся на расстоянии $3$ в графе $\Gamma$. Нахождение параметров $\Gamma_3$ по массиву пересечений графа $\Gamma$ является прямой задачей. Нахождение массива пересечений графа $\Gamma$ по параметрам $\Gamma_3$ является обратной задачей. Ранее обратные задачи были решены для $\Gamma_3$ Махневым А.А. и Нировой М.С.

The introduction of generic direct-acting antivirals (DAAs) in Egypt is associated with a superior cure rate of hepatitis C virus (HCV) infection. However, the course of progressive liver damage and developing liver related complications in patients with sustained virologic response (SVR) remain unclear. This study was designed to examine the long-term outcomes of generic DAA-induced virological cure in a real-life cohort of HCV patients with or without comorbid schistosomiasis. We prospectively enrolled a cohort of 506 recently cured HCV patients (437 Child–Pugh class A [Child-A] and 69 Child–Pugh class B [Child-B]). All patients were clinically evaluated at different time points during a 2-year follow-up (November 2018 to February 2021). Over the course of treatment and follow-up, 77 (15.2%) patients (42 [9.6%] Child-A and 35 [50.7%] Child-B) experienced complications at different time points. The overall mortality rate was approximately 1/1,000 person-years. The incidence of hepatic insufficiency was approximately 5.5/1,000 person-years, and that of de novo hepatocellular carcinoma (HCC) was approximately 8.3/1,000 person-years. A sustained improvement in liver indices up to 2 years of follow-up was observed. In the Cox regression model, pretreatment decompensated cirrhosis predicted the occurrence of adverse liver events and HCC after therapy. In conclusion, in HCV patients with advanced cirrhosis or coexisting hepatic schistosomiasis, generic DAA-induced SVR remains robust with favorable clinical outcomes although the risk of hepatocarcinogenesis cannot be eliminated. Surveillance of patients with treated HCV infection is an important aspect of postcure care for early detection and management of liver disease-related adverse events.

Introduction: It is challenging to predict fetal macrosomia before delivery. This study aimed at assessing predictors of fetal macrosomia at Iringa Regional Referral Hospital in Tanzania from June to December 2020. Method: An unmatched case-control study with 216 participants of whom 72 were cases - women who delivered babies weighing ≥ 4000g - and 144 were controls - women who delivered babies weighing 2500g to 3499g. The purposive sampling technique described below was employed to recruit both controls and cases. SPSS version 25 software program was used for data entry and analysis.Results: Of the 216 participants, 116 (53.7%) were aged between 25 – 34 years (standard deviation 6.0). The majority of 132 (61.1%) delivered at a gestational age of 37 – 39 weeks + 6 days of whom 17 (23.6%) were cases and 115 (79.86%) were controls. The predictors of fetal macrosomia were advanced gestation age (AOR=8.10, 95% CI 3.66-17.91, p=<0.0001) and diabetes mellitus during pregnancy (AOR =14.94, 95% CI 1.60 -39.91, p= 0.0178).Conclusion: Women with higher gestational age and gestational diabetes mellitus are at an increased risk of delivering a baby with macrosomia at Iringa Regional Referral Hospital. An early plan for the mode of delivery, such as labour induction, will aid the prevention of advanced gestational age. Ensuring a healthy diet and physical exercises in our communities will help to reduce diabetes mellitus and hence fetal macrosomia.
Neuroscience education in Africa, prospects and challenges
Authors: Olabode Ekerin , Calistus Okechukwu K.
Published: February 2022

This review explores the scope of neuroscience education, the current and future trends and evaluates the limitations hindering the evolution of neuroscientific studies and research in Africa. Neuroscience is one of the most poorly addressed fields of study in Africa evidenced by the paucity of available data. Africa has a lot to do to improve neuroscience research. More government financing is needed if the continent’s research sector is to continue to expand. International scientific collaborations are an important part of integrating into the global research community. African neuroscientists must also participate in policy and decision-making to urge governments to finance research into Africa’s specific requirements.

Published: February 2022

The current data mining algorithm has the problem of imperfect data mining function, which leads to the algorithm taking too long time. This paper designs a data mining algorithm based on BP neural network. Analyze the basic structure of the data mining algorithm, obtain the data characteristics of the multi-objective decision-making, adjust the convergence speed with the distributed computing technology to keep the inertia factor state unchanged, construct the local minimal discrete model, measure the interest of the model, calculate the optimal output value of the network using the BP (Back Propagation) neural network model, and complete the improved design of the data mining function. Experimental results: The average computational time consumption of the designed data mining algorithm is 559.827 seconds, which saves 145.975 seconds and 174.237 seconds respectively than other traditional algorithms. It is proved that the data mining algorithm based on BP neural network reduces the computational time consumption, improves the performance of data mining, and has high application value.

Published: February 2022

The Non-Hodgkin’s Lymphoma Large B Cell (LBDGC) is a cancer of the lymphatic system that develops when an error occurs in the production of lymphocytes leading to the production of abnormal cells. Several genes govern the occurrence of NHL; one of the most widespread is the β-catenin one. This is why we tried in this study to evaluate the β-catenin gene effect on the induction of Non-Hodgkin’s Lymphoma Large BCell.
THE BLEEDING OF THE SHEEP BREED '' HAMRA ''
Authors: Ayachi Ahmed
Published: February 2022

Because of its extent and geographical diversity, Algeria has a very rich animal heritage. Among its animals, sheep whose roots, so deep, become bogged down well beyond the Numidian period, constitute a heritage that is both natural and genetic, highly varied. However, it is mainly the two steppe breed, namely "Hamra" in the West and "Ouled Djellal" in the East, which have left their mark on the richness of this living national heritage. It should be known that in the early days of French colonization, large quantities of sheep from Algeria, stolen from different steppe regions of the country, were exported to France, but also to its colonies. However, research on this subject reveals that a strong preference for the Hamra breed has quickly seized the brokers responsible for the collection of livestock for export. Thus from 1929 until the last years of colonization, more than a million heads of sheep "Hamra" will be exported, annually, by the French colonists to the metropolis, more exactly to the port of Marseille. Embarkations were made from the port of Arzew, in the West, and the port of Algiers, for the Center and the East. Currently, to make their farms profitable, sheep owners have chosen the ovine genetic type which makes it possible to achieve the best economic and financial profits. And so it was from the time of the mechanization of the steppe and the drought of 1970 that the regression process of the ovine breed Hamra was accentuated. In fact, all thebreeders of the Hamra breed who were formerly hampered by the distances and especially by the reliefs and the lack of means of transport of the cattle began to use heavy breeding rams such as the Ouled Djellal type. This led, over time, to the genetic absorption of the Hamra sheep, which occurred in favor of the Ouled Djellal breed and its crosses, which now constitute more than 65% of the national herd population. Only 20% of which are purebred. Thus, after forty years and in the absence of a policy of management of animal genetic biodiversity, the Hamra breed is now in danger of total extinction. This could be the loss of a national genetic resource but also a heritage that is more than a thousand years old. In fact, apart a few former breeders who still hold a small number of sheep descended from the Hamra breed, this Algerian sheep breed has become unknown today by the majority of young breeders. Pending the reaction of the public authorities, the association for the preservation and promotion of the Hamra breed (APPRHamra), newly created in the wilaya of Naama, engaged with the scientific community (geneticists, agronomists, veterinarians ...) a action to promot this breed and militates in for the preservation of this animal heritage dating back several centuries.
DEVELOPMENT OF BODY MASS AND SEXUAL SIZE DIMORPHISM IN DANISH RED FOXES (VULPES VULPES)

Published: February 2022

In this study, we examine the development of body mass and sexual size dimorphism (SSD) in 178 juvenile wild Danish red foxes from 99 litters using piecewise analyses of regression lines for age versus weight. When fox cubs are younger than 100 days, only slight (SSD=1.7%) and no significant difference (t-test: t=1.2, p=0.24) was found in the mean weight of males (2.03± kg) and females (1.93± kg), and no significant difference was found in the slope of regression lines for males and females (F=0.97E-5, p = 0.99). In the growth period between 100 days of age and mating around 275 days of age, the regression line in males steepens more than that of females (difference in slopes, F=5.9, p<0.02) and the difference in mean weight of the sexes become highly significant (SSD=7.4%, difference in mean t=4.6, p=2.2E-5). After mating the growth curve levels off i.e. the slope of the regression lines for age versus weight is not significantly different from zero. Yearly variation was revealed in the growth rate of juvenile foxes (difference in slope for males; F=3.9, p<0.01 and females; F=8.6, p<0.001). Conclusion: SSD in red foxes mainly develop as a result of a faster grow rate in males between indepency and maturity. Ontogony of red foxes may genetically be disposed to prevent males outcompeting females in the early stages of life (<100 days), when cubs are still fed by adults and the increase in SSD before mating, may be an adaption to selective forces benefitting larger males. The growth rate of juvenile foxes of both sexes is influenced by environmental variation in different years.

The Brahman was   one of the exotic breeds imported into Malaysia to help boost the local beef cattle industry. Due to its adaptability and the productive performance, it is considered as a suitable breed for the country, as well as a breed for use in crossbreeding. This study aimed to assess the genetic variability in the Brahman breed in Malaysia using microsatellite markers. Twenty microsatellite loci,BM1818, BM1824, BM2113, CSRM60, CSSM66, ETH3, ETH10, ETH152, ETH185, ETH225, HAUT24, HAUT27, HEL1, HEL5, HEL9, HEL13, ILSTS005, ILSTS006, INRA005 and INRA023, were used to screen a random sample of 32 of Brahman cattle at the Brahman nucleus herd at DVS Livestock Center in Kuala Berang, Terengganu. A total of 151 alleles were detected. The number of alleles per locus varied between 6 and 10 with an average of 7.6. The effective number of alleles (Ne) range between 2 and 7 with average of 3.8. The observed heterozygosity values (0.26 - 0.83) were lower than the expected heterozygosity values for almost all loci. The overall mean heterozygosity was 0.54. The values of inbreeding coefficient (FIS) based on the individual locus were generally positive. Thirteen loci deviated from HWE equilibrium (p<0.05). This study showed that there was low genetic variability in the Brahman nucleus herd in Malaysia

The objective of the study was to establish and refine a method for the genomic characterization of European hedgehogs in Denmark using the second-generation genotyping technique, genotyping by sequencing (GBS). Single nucleotide polymorphisms (SNPs) were filtered with a read coverage between 20 - 100 and a maximum number of missing data of 25 %. Individuals with > 25 % missing data were removed yielding a total of 2.4 million SNPs, and after filtering for Minor allele frequency (MAF) >1 %, 2902 SNPs remained. Approximately half of the individuals analysed contained less than 75% of the selected SNPs, and were removed, resulting in a sample size of 30. We estimated inbreeding coefficients (F), observed (HO), expected (HE) and unbiased expected (uHE) heterozygosity and the percent of polymorphic loci (P%). We tested for deviations from Hardy-Weinberg equilibrium (HWE) and patterns of isolation by distance (IBD). We assessed the genetic structure of the sampled individuals based on a Bayesian clustering method, and tested for recent population expansion or decline. We found a P% = 94.5%, a uHE and HE of mean ± SE; 0.31 ± 0.04 and 0.30 ± 0.02, respectively and an HO of 0.290 ± 0.03. The heterozygosity deficiency was reflected in a positive F-value; 0.1 ± 0.01 and a significant deviation for HWE (p < 0.05). The Mantel test for association between the genetical and geographical distances of populations was not significant (b = 0.007, R = 0.145, p > 0.05). The significant and positive F-value found, was explained by inbreeding, genetic substructure and low effective population size (Ne) which are all consequences of habitat fragmentation. We failed to detect recent signs of a population bottleneck or expansion. Further studies on a larger scale are needed to obtain a general view of the conservation status of the Danish hedgehog population.
