Assessing hand and global disability in a cohort of Algerian patients with systemic sclerosis: Construct validities of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire.

Objective: The study aimed to assess the construct validity of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire in Algerian patients with systemic sclerosis.

Methods: Consecutive Algerian patients who fulfilled the American College of Rheumatology/European League Against Rheumatism criteria for systemic sclerosis were included. In addition to disease characteristics, global disability and hand disability were assessed using the Arabic Health Assessment Questionnaire and the Arab Hand Function Index, respectively.

Inborn Errors of Immunity in Algerian Children and Adults: A Single-Center Experience Over a Period of 13 Years (2008-2021).

Background: Inborn errors of immunity (IEI) predispose patients to various infectious and non-infectious complications. Thanks to the development and expanding use of flow cytometry and increased awareness, the diagnostic rate of IEI has markedly increased in Algeria the last decade.

Aim: This study aimed to describe a large cohort of Algerian patients with probable IEI and to determine their clinical characteristics and outcomes.

A case of Right Hepatic Artery anterior to the common hepatic duct: A not so rare variation.

Introduction And Importance: The hepatic arteries may be subject to anatomical variations that can cause operating difficulties with a risk of iatrogenic vascular injuries. A perfect knowledge of anatomy is an essential prerequisite for both surgeons and interventional radiologists.

Case Presentation: During a duodenopancreatectomy for a pancreatic head tumor in a 46-year-old man, we observed an anatomical variation regarding the course of the right hepatic artery (RHA).

Epidemiology of breast cancer in women based on diagnosis data from oncologists and senologists in Algeria.

Background: Breast cancer (BC) is a major health issue threatening women's life. No reliable epidemiological data on BC diagnosed by oncologists/senologists are available in Algeria.

Methods: The BreCaReAl study, a non-interventional prospective cohort study, included adult women with confirmed BC in Algeria.

Modelling fire hazard in the southern Mediterranean fire rim (Bejaia region, northern Algeria).

The southern rim of the Mediterranean Basin (MB) has a long fire history but fire hazard is poorly investigated in comparison to the northern rim. We built a fire database using MODIS data (2001-2015) for an area typical of the northern coastal Algeria (Bejaia region) in order to decipher the role of environmental and anthropic controls on the fire frequency and the area burnt. We found a high role of bioclimate, which controls the fuel dryness, ignitability, and biomass.

Fuzzy-Super twisting control implementation of battery/super capacitor for electric vehicles.

The present paper deals with a real-time implementation of a novel Fuzzy logic energy management strategy (EMS), applied to a battery-super capacitor hybrid energy system and associated with a permanent magnet synchronous motor (PMSM) which emulates the traction part of an electric vehicle (EV). On the sources side, the fuzzy logic supervisor acts in a smart way to permute smoothly between the various operations modes via an efficient power frequency splitting. In addition, it permits a quite regulation of both the DC bus and the super-capacitor (SC) voltages regardless of the speed profile variations to ensure an optimal power flow to the load and to keep the SC operation in a safe voltage range while providing or absorbing power in transients.

Report on spp. (Diptera, Gasterophilidae) of Horses in Algeria: Prevalence, Intensity, and Monthly Variations.

The composition, prevalence, and seasonal dynamic of species were studied at the slaughterhouse of Constantine region (East Algeria) in 128 horses over an 18 months period. Our survey revealed that 124 (96.9%) horses were infected with a mean intensity of 161 larvae of spp.

Association of CAT-262C/T with the concentration of catalase in seminal plasma and the risk for male infertility in Algeria.

Catalase (CAT) plays a central role in the protection of different cell types against the deleterious effects of hydrogen peroxide. In human, CAT is implicated in many physiological and pathological conditions including idiopathic male infertility. In this study we examined the association between CAT levels in seminal plasma with different sperm parameters and with CAT-262 C/T polymorphism and their risk for idiopathic male infertility in Algeria.

Facial Nerve Function and Quality of Resection in Large and Giant Vestibular Schwannomas Surgery Operated By Retrosigmoid Transmeatal Approach in Semi-sitting Position with Intraoperative Facial Nerve Monitoring.

Introduction: Large and giant vestibular schwannomas pose a real problem in their management. The preservation of facial nerve function may limit tumor resection despite the use of intraoperative monitoring of the facial nerve. In Algeria, vestibular schwannomas represent 5% of all intracranial tumors operated on, 80.

Arrested development of abomasal trichostrongylid nematodes in lambs in a steppe environment (North-Eastern Algeria).

Arrested development of abomasal trichostrongylid nematodes was studied in 30 permanent grazing lambs on a large farm in the North-East of Algeria. The steppe climate has cold winters and hot and dry summers. The lambs were monitored monthly for gastrointestinal nematodes using nematode faecal egg counts, from February 2008 to February 2009.

A new approach for semiconductor parameter extraction using cathodoluminescence and artificial neural networks.

In this paper, a new parameter extraction technique that jointly extracts four semiconductor-related parameters from theoretical/experimental cathodoluminescence data collected as a function of electron-beam energy is presented. The extraction technique is based on feed-forward artificial neural networks (ANN) where the ANN is trained to learn the inherent relationship between the input parameters (absorption coefficient α, diffusion length L, dead layer thickness Zt, and relative quantum efficiency Q) and the output parameter (CL intensity versus electron beam energy). After the training of the ANN, it is possible to observe the reverse process and extract the four parameters from any CL curve using an exhaustive search method.

The toxic effects of nickel chloride on liver, erythropoiesis, and development in Wistar albino preimplanted rats can be reversed with selenium pretreatment.

The exposure to nickel chloride (NiCl₂) can cause hematotoxicity and hepatotoxicity and canaffect development. The present study pertains to the protective effect of selenium (Se) against NiCl₂-induced toxicity in preimplanted Wistar albino rats. The subcutaneous (s.

Time of initial detection of fetal structures and anatomic differentiation by using B-mode ultrasound examination in bitches.

Ultrasonographic examinations of 10 pregnant bitches with known breeding dates were made on successive days to establish the identifiable characteristics of pregnancy. Subsequent serial examinations were made to sonographically characterize normal canine prenatal development based about the first mating. The initial detection of the fetal and extra-fetal structures were as follows: gestational sac at day 17.

Increased lipid peroxidation in pregnant women after iron and vitamin C supplementation.

Iron overload could promote the generation of free radicals and result in deleterious cellular damages. A physiological increase of oxidative stress has been observed in pregnancy. A routine iron supplement, especially a combined iron and vitamin C supplementation, without biological justifications (low hemoglobin [Hb] and iron stores) could therefore aggravate this oxidative risk.
