Abstract
Aim: Functional gastrointestinal (GI) disorders are recognized as a major public health concern worldwide. These disorders involve persistent digestive symptoms indicative of digestive tract dysfunction.Materials and Methods: A survey examining the utilisation of probiotics and medicinal plants as supplementary treatments was conducted on 160 patients with GI disorders at healthcare institutions in Saïda from March to April 2023 using questionnaires that had been previously adapted and tested for reliability with Cronbach's alpha test. Raw data collected through the questionnaires were transferred to a database and analysed using SPSS software.Results: Overall, 49.38% of participants possessed knowledge of or actively utilised probiotics; such awareness was strongly associated with the participants' educational attainment (p = 0.029). The noteworthy probiotic supplements were Biocharbon (36.09%), Lactocil (15.38%), Smebiocta (13.61%), Ultrabiotic Adult (12.43%), Effidigest (12.43%), and Ultralevure (7.69%). During crisis, individuals tended to consume natural goods rich in probiotics, including yoghurt (13.26%) and fermented milk (8.60%), as well as foods rich in prebiotic fibre, including vegetables (18.99%), fruits (13.26%), wheat (9.67%), bran (7.52%), rye (6.81%), and oat flakes (6.45%). Additionally, 77.56% of patients used medicinal plants during crises, with Mentha spicata (12.2%), Thymus vulgaris (11.3%), Pimpinella anisum (8.5%), Cuminum cyminum (8.0%), Punica granatum (7.8%), Trachyspermum ammi (7.5%), and Senna acutifolia (7.0%) being the more commonly favoured options in phytotherapy. The main focus of these herbs was to alleviate bloating (57%), constipation (30.12%), and diarrhoea (12.87%) (p < 0.001). The most frequently utilised plant parts were leaves (47.30%), seeds (25.21%), and bark (13.21%). Most patients (82.91%) favoured infusion as their preferred consumption method, and approximately 85.43% believed in phytotherapy's ability to extend symptomatic relief.Conclusion: The understanding of probiotics is still in its infancy, whereas phytotherapy is more widely accepted by patients. Nonetheless, patients are open to the exploration of natural alternatives to conventional medicines.

Abstract
OBJECTIVE This study aims to analyze and compare the postural balance between two aquatic sports where vertical vs. horizontal body positions (i.e., windsurfing vs. swimming) are key techniques for both sports. SUBJECTS AND METHODS Eight volunteer windsurfers and eight swimmers agreed to participate in this study. Each of the assessments was a 2D kinematic analysis of frontal and/or sagittal balance (i.e., in bipedal and/or unipedal stance) of the center of mass velocity on wobble board (Single Plane Balance Board) on hard and/or soft surface. Kinematic analysis was performed in 2D using two action-cams. Data were digitized using the video-based data analysis system SkillSpector. RESULTS The results showed that the ANOVA, with repeated measures on 1 factor, showed a significant difference (p<0.001) between groups (i.e., swimmers and windsurfers) in all variables and in the interaction between ground (i.e., hard and foam) and group (p<0.01) in all tests in sagittal plane. Furthermore, for the ground*group interaction, a study (i.e., paired t-test) of the difference between balance (i.e., in frontal and/or sagittal plane) on hard and soft ground for each group showed that windsurfers had no difference in body sway in frontal and/or sagittal plane between hard and soft surface in bipedal stance. CONCLUSIONS We concluded that the windsurfers showed better postural balance performances compared to swimmers in the bipedal posture on hard and soft ground. Also, the windsurfers presented a better stability level compared with the swimmers.

Abstract
This study focuses on certain characteristics of the jump take-offs in rhythmic gymnastics (RG). Rhythmic gymnasts always perform their jumps with the same preferred run-up technique, proceeded by a chassé-step in most of the cases. The overall idea was to analyse other step-techniques that could be performged on one-leg, which could prepare jumps. The aim of this study was to compare kinetic and kinematic variables between three-stag ring leaps with and without throwing-ball, performed using the glissade-step as a preparatory phase for take-off with one-leg these were as follows: glissade stag ring leap without-ball (GSWB), throw-ball glissade stag ring leap (TBGS) and glissade throw-ball stag ring leap (GTBS). Seven members of the Tunisian RG national team took part in this study. The technical elements were recorded in 2D using two-cameras on a specially designed floor carpet where a force-plate was integrated. The results showed that the three-leaps had significant impacts on the performance variables, especially on the force, the velocity and the flexibility. The GTBS was the most effective leap as the throw took place during the jump, which has increased its technicality and the applied physical variables, the vertical force, the rate of force development, the horizontal and vertical velocities and displacements.

Abstract
Background: Peripartum anesthesia may consist of parenteral opioids and/or regional analgesia. There is only limited data in the literature comparing both methods in daily obstetric practice. This observational study investigated the opioids pethidine and meptazinol as well as regional analgesics with regard to their administration, efficacy, side effects and subjective maternal satisfaction with therapy. The rates of secondary regional analgesia administration after administration of the respective opioid served as a means of evaluating treatment. Methods: This study collected data on pain management during vaginal delivery in a German university hospital over a twelve month period. Severity of pain was measured intrapartum using a numerical rating scale. Maternal, neonatal and delivery-related data were obtained postpartum from the clinical records and from the mothers using a questionnaire. Results: The study is based on data obtained from 449 deliveries. Pain relief achieved by the administration of pethidine and meptazinol was similarly low; maternal satisfaction with the respective therapy was high. Meptazinol was usually administered intravenously (83 % vs. 6 %; p < 0.001), repeatedly (27 % vs. 6 %; p < 0.001) and closer to the birth (1.9 ± 2.7 h vs. 2.6 ± 2.8 h; p < 0.05) compared to pethidine. Secondary regional analgesia was more common after the administration of pethidine (16 % vs. 8 %; p < 0.05). Regional analgesia resulted in greater pain relief compared to opioid therapy (78 % vs. 24 % after 30 min; p < 0.001) and was associated with longer times to delivery (7.6 ± 2.5 h vs. 5.7 ± 2.5 h; p < 0.001) and higher levels of maternal satisfaction with therapy (6.1 ± 1.2 vs. 4.8 ± 1.6 on a 7-point scale; p < 0.001). Conclusion: In daily clinical practice, meptazinol can be adapted more readily to changes during birth and requires less secondary analgesia. Regional neuraxial analgesia was found to be an efficacious and safe way of managing labor pain.

Abstract
Formulating healthy food rich in omega 3 fatty acids requires prior knowledge of the parameters influencing their bioavailability and their metabolic fate. In this context, we studied the effects of various emulsifiers widely used in the food industry, on the gastrointestinal lipolysis of flaxseed oil emulsions in an in vitro model and on the intestinal absorption and lymphatic secretion of alpha-linolenic acid (ALA) in rats. In vitro data showed that the emulsification of flaxseed oil with soya lecithin improved the gastric lipolysis of the oil (+30%), while the presence of Tween 80 or of sodium caseinate decreased it (-80% and -40%, respectively). The in vivo data demonstrated that the intestinal absorption and the lymphatic secretion of ALA were improved with soya lecithin (Cmax = 24 mg mL(-1)) and reduced in the presence of sodium caseinate (Cmax = 7 mg mL(-1)) compared to unemulsified flaxseed oil (Cmax = 16 mg mL(-1)); Tween 80 had no effect. In addition, the synthesized chylomicrons were notably larger and more numerous with soya lecithin whereas they were smaller in the presence of sodium caseinate (p < 0.05). This study shows that the intestinal bioavailability of ALA was increased by the emulsification of flaxseed oil with soya lecithin via an improved lipolysis, favouring the intestinal absorption of ALA and the secretion of many large chylomicrons in lymph.

Abstract
The aim of this study was to assess the potential subacute toxicity of zinc oxide (ZnO) nanoparticles (NPs) in Wistar rats in comparison with reference toxicant, zinc chloride (ZnCl2), of a non-nanoparticulate form. We therefore studied the relationships between zinc (Zn) accumulation, liver and kidney trace element levels, and plasmatic biochemical parameters. Rats in all groups were treated by intraperitoneal injection of ZnO NPs and/or ZnCl2 solution (25 mg/kg) every other day for 10 days. The contents of trace element in the liver and kidney were slightly modulated after ZnO NPs and/or ZnCl2 solution exposure. The same treatment increased the aspartate aminotransferase activity and uric acid concentration. However, ZnO NPs or ZnCl2 solution decreased the creatinine levels, whereas the combined intake of ZnO NPs and ZnCl2 decreased the glucose concentration. Interestingly, the analysis of the lyophilized powder of liver using the x-ray diffractometer showed the degradation of ZnO NPs in ZnO-treated group, instead there is a lack of NPs ZnO biosynthesis from the ZnCl2 solution injected in rats. These investigations suggest that combined injection of ZnO NPs and ZnCl2 solution has a possible toxic effect in rats. This effect could be related to Zn2+ ion release and accumulation of this element in organs. Our findings provide crucial information that ZnO appeared to be absorbed in the organs in an ionic form rather than in a particulate form.

Abstract
Owing to its selectivity, diffraction is a powerful tool for analysing the mechanical behaviour of polycrystalline materials at the mesoscale (phase and/or grain scale).In situneutron diffraction during tensile tests and elastoplastic self-consistent modelling were used to study slip phenomena occurring on crystallographic planes at small and large deformation. The critical resolved shear stresses in both phases of duplex stainless steel were found for samples subjected to different thermal treatments. The evolution of grain loading was also determined by showing the large differences between stress concentration for grains in ferritic and austenitic phases. It was found that, for small loads applied to the sample, linear elastic deformation occurs in both phases. When the load increases, austenite starts to deform plastically, while ferrite remains in the elastic range. Finally, both phases undergo plastic deformation until sample fracture. By using an original calibration of diffraction data, the range of the study was extended to large sample deformation. As a result, mechanical effects that can be attributed to damage processes initiated in ferrite were observed.

Abstract
Several epidemiologic studies have demonstrated during the last 50 years an increased incidence in testis cancer, male genital tract malformations (cryptorchidism and hypospadias) and a decrease in sperm quality in men. These three pathologies seem to be linked and to belong to the testicular dysgenesis syndrome (TDS). It was suggested that TDS is a consequence of intra-uterine exposure to environmental compounds that disrupt the metabolism of native hormones. Such substances are so called endocrine disruptors (EDs). EDs are present in our daily environment such as food and water (through the use of pesticides), cosmetics, house-care products etc. Experimental models have been carried out to (i) establish a link between EDs exposure and SDT and (ii) identify the mechanisms that are involved in. After a brief definition of EDs and having underlined the importance of the window of exposure to EDs, several mechanisms will be described such as (i) intergenerational transmission (epigenetic), (ii) programmed cell death of testicular cells, (iii) modification of the androgenic signal and (iv) role of the germ cells-nourishing cells. To conclude, we will try to propose some biomarkers that would be useful to identify the potential link between fetal exposure to anti-androgenic EDs and male testicular pathology.

Abstract
This national survey aims to evaluate opioid availability and prescription by pharmacists in Tunisia and to examine pharmacists' attitude regarding Tunisian law. We surveyed a sample of 300 pharmacists randomly selected from the National Council of Pharmacists list and using the random table. This study started in September 1999 by sending to pharmacists a confidential questionnaire asking about the importance, the rate of sale and the availability of analgesics in their pharmacy. It also tried to determine pharmacists' opinions regarding Tunisian law. A total of 157 pharmacists out of 300 responded to the survey (52 per cent), 95 per cent were working in pharmacies and 15 per cent in hospitals. Analgesics were estimated to be important to very important in their work in 84 per cent and less important in 16 per cent of cases. They were given under advice with great importance in 85 per cent of cases and with less importance in 15 per cent of cases. Analgesic self-medication was frequent in 95 per cent of cases and rare in 4 per cent of cases. Analgesics of levels 1 and 2 were often to always available in 97 per cent of cases and rarely available in 1.5 per cent of cases. Some 84.7 per cent of pharmacists had opioid supplies and 8.9 per cent had no opioids in stock and 6.4 per cent hadn't given a response. 30 per cent of pharmacists think that the 7 days law for opioid prescription should be modified and 66 per cent think it should not, fearing illicit use, fraud and dependance. Pharmacists think that the minimal list of opioids to be stocked in a pharmacy is sufficient because of low demand.

Abstract
BACKGROUND Inhaled corticosteroids (ICS) have become first line agents in the management of moderate-to-severe asthma. Long-term use of ICS is associated with decreased bone mineral density (BMD). OBJECTIVE To investigate the prevalence of BMD loss and its severity in women with asthma on long-term ICS. METHODS Fifty-six women with asthma on long-term ICS, attending an inner-city allergy clinic were selected to undergo bone densitometry in order to evaluate the association between BMD and the long-term use of ICS at different dose ranges. RESULTS Women (60.7%) had decreased BMD either at the lumbar spine or hip region. Among postmenopausal women, 17.1% of those <65 years and 42.9% of those > or =65 years had osteoporosis compared with 5.7% (95% CI-3.9% to 8.5%) of those <65 and 29.3% (95% CI-25.7%-33.5%) of those > or =65 years reported in the NHANES III survey. The prevalence of low BMD increased as ICS dose increased from 5% in the low dose group to 50% in the high dose group (P < .002). There were significant linear trends of decline by dose in mean BMD for the hip (P < .001) and the lumbar spine (P < .002). Women who received medium or high doses of ICS had significantly greater bone loss than those receiving low doses. CONCLUSION The findings of increasing BMD loss with increasing ICS dose reinforce the necessity to monitor BMD periodically in women on ICS, particularly in the high risk postmenopausal group and those on medium to high doses. There should be a concurrent continual attempt to lower the dose by supplemental nonsteroidal controller medications and providing nutritional and pharmacologic treatment of identified BMD loss in these patients.

Abstract
We compared beta irradiation (106Ru/106Rh) to gamma irradiation (125I) on the normal rabbit eye, using ophthalmic plaques to deliver doses similar to those recommended in man for choroidal melanoma treatment. A detailed dosimetry was performed and the animals were followed up by clinical and histological examinations during 1 year. The mean total doses were either comparable, or larger with iodine-125, but the globes treated with ruthenium-106 exhibited more damaging effects: total destruction of the chorioretina on the plaque site, abnormalities of the retinal vessels and of the close nerve fiber layers, cavernous atrophy of the optic nerve. In the eyes treated with iodine-125, only the external retinal layers were destroyed.

Abstract
We have evaluated the effects of the volume and speed of administration of local anaesthetic during peribulbar anaesthesia. One hundred and forty patients scheduled for cataract surgery were randomly allocated to one of four groups of 35. Each patient received an injection of the same mixture of lignocaine, bupivacaine and hyaluronidase. Patients in group A were given 9 ml at a speed of 5 ml.min-1, group B were given the same volume at 12 ml.min-1, group C were given 13.5 ml at 5 ml.min-1 and group D were given 13.5 ml at 12 ml.min-1. A significantly higher incidence of satisfactory akinesia was found in group D, whose pain score at injection was no higher than for the other groups. Large volumes of local anaesthetic significantly affected intra-ocular pressure. The incidences of early and late ptosis or diplopia were not affected by either the rate of injection or the volume of local anaesthetic.

Abstract
The norepinephrine transporter protein (NET) is the presynaptic reuptake site for norepinephrine and a site of action for several drugs with CNS effects, some of which are therapeutically useful and some of which are drugs of abuse. We used PCR with a somatic cell hybrid panel to obtain a provisional assignment to chromosome 16. We then typed a genetic polymorphism at the NET1 locus in three large multigenerational families and used linkage analysis to confirm the preliminary assignment and to refine the localization to 16q, near the HP locus. Finally, we typed the NET1 RFLP on the CEPH families and the additional linkage data localized NET1 to 16q13-q21, flanked by D16S71 (centromerically) and HP (telomerically).
