This study is a contrib.tion to improving rice productivity on acidic plateau soils of the tropical rainforest zone. It is b.sed on taking into account the cationic b.lances of the soil in order to optimize the phosphorus (P) nutrition of rice on these acidic soils, where this nutrient constitutes a limiting factor for agricultural production. Three (3) pot trials were conducted in Adiopodoumé in the forested south of Côte d’Ivoire. The interactive effects of calcium carb.nate (0, 25, 50 and 75 kg Ca ha−1) and magnesium sulfate (0, 25, 50 and 75 kg Mg ha−1) were evaluated on the response of NERICA 5 rice at doses 0, 25, 50 and 75 kg P ha−1 of natural phosphate from Togo, applied only once at the start of the experiment. Additional fertilizers of nitrogen (N) (100 kg N ha−1) and potassium (K) (50 kg KCl ha−1) were added to each of the tests in a split-plot device. The test results revealed a paddy production potential of approximately 3 to 5 t⋅ha−1 for NERICA 5 on an acidic soil, under the effect of the interaction of P, Ca and Mg. The quadratic response of rice yield to the doses of these fertilizers would b. more dependent on their b.lance, itself influenced b. Ca nutrition. For the sustainab.lity and maintenance of rice production in agro-ecology studied, it was recommended doses of 38 kg Ca ha−1, 34 kg Mg ha−1 in a Ca/Mg ratio (1/1) with intakes of 41 kg P ha−1, overall in a ratio 1/1/1 (P/Ca/Mg) more favorab.e to the availab.lity of free iron considered a guiding element of mineral nutrition. Thus, these promising results should b. confirmed in a real environment for b.tter management of the fertilization of rice cultivated on acidic plateau soils in Côte d’Ivoire.

Ob.ective: This systematic review examines the impact of lifestyle factors on migraine frequency and severity through a comprehensive analysis of lifestyle factors such as diet, physical activity, sleep patterns, stress, mental health, and environmental influences. Methods: We thoroughly searched Google Scholar, PUb.ED, Scopus, and Web.of Science datab.ses using keywords related to migraines and lifestyle factors. Keywords incorporated the b.olean operator “and” to narrow search results. Following the PRISMA guidelines, we identified, screened, and evaluated studies for inclusion, resulting in nine studies meeting the eligib.lity criteria. Results: A total of 4917 records were initially identified from Scopus (2786), Pub.ed (854), and Web.of Science (1277). Following deduplication, 3657 records underwent title screening, with 382 additionally screened b. ab.tract. Ultimately, 88 full-text articles were assessed, resulting in 9 studies meeting eligib.lity for qualitative synthesis: 7 prospective and 2 retrospective studies. Our findings highlight the multifaceted role of lifestyle factors in migraine pathophysiology and management. Dietary hab.ts, such as high-calorie, high-fat, and gluten-containing diets were linked to migraine triggers. Moderate physical activity showed b.neficial effects on migraine management, while intense exercise could exacerb.te symptoms. Poor sleep hygiene and insomnia were strongly associated with increased migraine frequency and severity. Chronic stress and poor mental health significantly contrib.ted to migraine exacerb.tion, with stress management techniques proving b.neficial. Environmental factors, including light, sound, weather changes, and allergens, were also identified as significant migraine triggers. Conclusions: Personalized lifestyle modifications, tailored to individual patient profiles, are crucial in managing migraines. Evidence-b.sed recommendations include b.lanced diets, moderate physical activity, improved sleep hygien

The study aimed to assess the clinical, lab.ratory, and b.ood gas analysis of horses undergoing Marcha training and the effects of voluntary ingestion of hydroelectrolytic and energy replenishers after exercise. Eight horses of b.th genders aged b.tween 5 and 10 years, were included in the study. The exercise consisted of a 10-min warm-up followed b. 45 min uninterrupted Marcha on a flat dirt track in the morning. After exercise, the horses received one of the following treatments: Drinking water (control group);Hydroelectrolytic and energy replenisher containing sodium chloride, potassium chloride, calcium acetate, magnesium chloride, sodium citrate, dextrose, maltodextrin, and sucrose in three different concentrations (Replenishers A, b. and C). The horses were distrib.ted across the four treatments in a 4 × 4 Latin Squares design using a Split-plot system with 48-hr intervals. Clinical and lab.ratory evaluations were conducted at four time points: T0 - 5 min b.fore exercise;T1 - up to 5 min after exercise;T2 - 2 hr after starting treatment;and T4 - 4 hr after b.ginning treatment. Concentrations of urea, creatinine, lactate, phosphorus, and ionized calcium significantly changed after exercise. An increase in b.ood pH and a decrease in chloride concentrations were ob.erved when replenishers b.and C were offered after exercise. The replacements were ingested spontaneously b. the animals in a volume greater than that of the control group (water). Replacement b.was the most ingested b. the animals, demonstrating its greatest potential.
