The influence of different norms of under-mulch-drip irrigation on diurnal changes of photosynthetic rates and chlorophyll fluorescence parameters of cotton was studied, in order to understand the physiological mechanisms of water-saving and high-yielding farming in Xinjiang. Results indicated that limited drip irrigation, which supplies 2/3 of 375 m3 ha-1, the widely-used irrigation norm in cotton cultivation in Xinjiang, caused a water deficit in cotton field. Compared with the proper drip irrigation, the leaf photosynthetic rate under limited drip irrigation decreased during 9:00 to 11:00 a. m. , and was significantly suppressed at midday, and then recovered afterwards. Using the chlorophyll fluorescence method, the absorption, transfer and transformation features of solar radiation by cotton leaf were investigated. Under limited drip irrigation, the variable fluorescence (Fv) and primary light transfer efficiency of PSII (Fv/Fm) in cotton leaves were reduced because of the high light intensities and high temperatures at noon, and the decrease in XinluzaoS was greater than that in Xinluzao6. Therefore, it could be concluded that Xinluzao6 has a higher drought-tolerance, and the Fv/Fm ratio could be used as a drought-resistance index for cotton.展开更多

Boll number per plant was lower in South and North Xinjiang, but the harvested plant population were nearly 1.5 times higher than that in Nangong, so total boll numbers per unit area were greater in South and North Xinjiang. Weight per boll in south and north of Xinjiang was 5.896.50 g and 5.43 6.12 g respectively, 24 to 51% heavier than that in Nangong. The diurnal temperature difference between day and night was relatively greater in Xinjiang than in Nangong, benefitting the accumulation of photosynthetic product in bolls. The temperature difference and total hours of sunshine in boll period are the main reasons for cottons higher boll weight and yield in Xinjiang than in Nangong.展开更多

The objective of this study was to describe the prognosis of urinary sphincter disorders during neurological conditions. Methods: This was a six-month analytical study conducted at the neurological unit of the Hôpital national Ignace Deen. Including patients with urinary sphincter disorders following a neurological condition;Chi-square, Fischer, and Student’s t-tests were used for variables with a p value less than 0.10 and then included in a logistic model with a significance level set at 0.05 and a 95% confidence interval. Results: We collected 1081 patients among whom, 324 presented, that is to say a frequency of 30%, which concerned subjects aged 57.3 ± 16.4 years with a slight female predominance 50.3%. Urinary incontinence (80.6%) was associated with complications such as urinary tract infection with a high proportion of cerebral damage (92.3%). HIV infection (P = 0.015), bedsores (P = 0.049), and inhalation pneumonia (P = 0.001) were the main poor prognostic factors. Conclusion: Urinary sphincter disorders are elements of poor prognosis, both vital and functional, concerning elderly subjects with a predominance of urinary incontinence. HIV infection, bedsores, pneumopathy are poor prognostic factors.展开更多

Objective: The aim of this document to describe the epidemiological, clinical, therapeutic and evolutionary aspects of facial cellulitis of dental origin in Bouaké. Methodology: This was a retrospective and descriptive study carried out in the stomatology and maxillofacial surgery department of the University of Bouaké Health centre over a period of 19 months (January 2018 to October 2019). All patients with facial cellulitis of dental origin were included. The parameters studied were epidemiological, clinical, therapeutic and evolutionary. Results: 179 patients were collected (hospital prevalence of 20.79%). The average age was 34 years (min 1-year-old and max 80-year-old). The sex ratio was 1.18. Among the patients, some were craftsmen (31.28%) and others were farmers (21.79%). The favourable factors included the nonsteroidal anti-inflammatory (77.65%) and traditional therapeutics (44.13%). The average number of days before consultation was 13 days (min 1 day and max 75 days). There were 7 cases of chronic cellulitis (3.91%) and 172 cases of acute cellulitis, including 107 (62.21%) circumscribed cellulitis, 51 (29.65%) diffused cellulitis, and 14 (8.14%) necrotizing fasciitis. The causal lesion was tooth decay (96.09%) and dental avulsion without antibiotherapy (3.91%). Incision and drainage was made in 145 patients (81%) necrosectomy surgery in 54 patients (30.17%). The mortality rate was 13.96%. Conclusion: Facial cellulitis of dental origin are clinically polymorphic with significant mortality prompting increased dental decay prevention actions.展开更多
