Ecotoxicological assessment of diffuse pollution using biomonitoring tool for sustainable land use in Thailand

Journal of Environmental Sciences 2010年第6期22卷 858-863页

As a developing country, Thailand has a significant issue with diffuse pollution of the soil ecosystem due to an indiscriminate use of agrichemicals and poorly regulated disposal of a wide variety of hazardous wastes. Practical risk assessment tools based on locallyoccurring species are needed to assess the effects of diffuse pollutants on the soil ecosystem in Thailand because reliance on soil criteria developed for overseas conditions may provide inadequate protection. Native soil organisms in Thailand may be more or less sensitive to contaminants compared to overseas test species. This article described a biological indicator approach for ecological risk assessment of diffuse pollution in the soil ecosystem of Thailand from pesticide application with the aim of developing standardized protocols using native species and locally generated data to better evaluate the ecological risks of non-point source soil pollution. It was found that ecotoxicological assessment provided a better understanding of the ecological impacts that diffuse pollution induced on Thai environmental conditions. Thai soil biota species were more sensitive to soil contaminants than similar species overseas. Soil series also had an influence on the ecotoxicology of contaminants to soil biota. Collembolan, Cyphoderus sp., was demonstrated as a useful alternative test species to Folsomia candida （international test species） for terrestrial ecotoxicological testing of Thai soils. In addition, the soil biota activities such as soil respiration and earthworm avoidance including soil biodiversity and the litter bag decomposition technique are also good tools to assess the effects of diffuse pollution by pesticides on the soil ecosystem of Thailand.

Introduction: Corticosteroid therapy used in rheumatology is effective but can lead to complications. The objective was to describe the complications of corticosteroid therapy in rheumatological practice at Ignace Deen University Hospital (Conakry). Methods: Cross-sectional study from July 1, 2022 to March 31, 2023. All patients who had been diagnosed with a rheumatological disease and who had received corticosteroid therapy were included. Results: Of the 1489 patients suffering from rheumatological diseases, 238 (15.9%) had received corticosteroid therapy. The average age of the patients was 48.5 ± 17.16 years with a female predominance (70.5%). The main indications for corticosteroid therapy were lower back pain due to probable disco-radicular impingement (35.8%) followed by rheumatoid arthritis (21.9%). The predominant method of administration was infiltration (56.9%). The average dosage was 24.2 ± 13.5 mg prednisone equivalent (range: 5 mg and 40 mg). Complications were present in 26 patients (10.9%) such as muscle cramps (3.8%), hypocalcemia (3.4%), edema of the lower limbs (3%), stimulation of appetite and weight gain (3%), high blood pressure (2.5%), hyperglycemia (2.5%). The occurrence of complications was associated with the high dose of corticosteroid (p = 0.014) and long-term use (p = 0.000). Conclusion: Corticosteroid therapy used in 15.9% of consultations in the rheumatology department of Ignace Deen University Hospital led to 10.9% of complications. These complications were related to the dose and duration of corticosteroid therapy.

Goal: To determine the type of comorbidity and highlight the complications of adenomectomy and comorbidities. Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association. Because their presence can affect effectiveness and lead to complications.

We show that there do not exist computable fimetions f_1(e,i).f_2(e,i).g_1(e,i),g_2(e,i)such that for all e,i ∈ω, (1)(W_(f_1)(e,i)-W_(f_2)(e,i))≤T(W_e-W_1): (2)(W_(g_1)(e,i)-W_(g_2)(e,i))≤T(W_e-W_i): (3)(W_w-W_i)≤T(W_(f_1)(e,i)-W_(f_2)(e,i))⊕(W_(g_1)(e,i)-W_(g_2)(e,i)): (4)(W_e-W_i)T(W_(f_1)(e,i)-W_(f_2)(e,i))uuless(W_e-W_i)≤T:and (5)(W_e-W_i)T(E_(g_1)(e,i)-W_(g_2)(e,i))unless(W_w-W_i)≤T. It follows that the splitting theorems of Sacks and Cooper cannot be combined uniformly.

Diabetes is a chronic pathology whose evolution is marked by micro and macroangiopathic complications. Optimal management can prevent the onset of complications and improve patients’ quality of life. Objectives: To determine the frequency of self-monitoring of blood glucose and to describe the errors found during self-monitoring in diabetic patients followed at the Endocrinology Department of Donka University Hospital in Guinea. Materials and methods: Descriptive cross-sectional study carried out between August and September 2020 involving diabetic patients followed up at the Endocrinology and Diabetology Department of the Donka National Hospital, CHU Conakry. Results: A total of 301 patients were enrolled, with an average age of 44.24 ± 21.01 years. 64.12% were female. Type 2 diabetes predominated in 64% of cases. The mean duration of diabetes was 6.14 ± 4.67 years, and 75.08% of patients lived in urban areas. Patients were on insulin in 36.21% of cases, insulin and biguanides (26.25%), hypoglycemic sulfonamide and biguanides (19.27%) and biguanides in 18.27% of cases. The frequency of self-monitoring of blood glucose was 43%, and 38% of patients made errors, notably reusing lancets (60%), not checking the expiration date (55.65%) and not washing their hands (48%). Conclusion: This study shows that self-monitoring of blood glucose is not performed by the majority of patients. Numerous errors were identified during blood glucose testing. Continued therapeutic education on the use of blood glucose meters will help empower patients and improve their quality of life.

This article describes the development of BP's Fischer-Tropsch catalyst, used for the conversion of carbon monoxide and hydrogen into liquid hydrocarbons. It covers the 18 year period from the early eighties, when laboratory scale preparations and micro-reactors were heavily used, right through to the present day with the commercial scale manufacture and proving of the finished catalyst in BP's new ＄86 million gas to liquids demonstration facility in Nikiski, Alaska. Extensive performance testing and scale-up experiments have been successfully carried out, all proof that a laboratory preparation can indeed be translated into a commercial manufacturing process. In addition, the resulting catalyst does not only meet the process design targets, but also exhibits enhanced stability and is tolerant to carbon dioxide. Above all, a commercial scale, fixed bed Fischer-Tropsch catalyst is now available and ready for licensing. Manufacturing procedures and quality control have all been successfully detailed and transferred to the commercial manufacturer.

Functional dyspepsia:Are psychosocial factors of relevance?

引用

World Journal of Gastroenterology 2006年第17期12卷 2701-2707页

作者： Sandra barry Timothy G Dinan Department of Psychiatry and Alimentary Pharmacobiotic Centre University College Cork CorkIreland

The pathogenesis of Functional Dyspepsia （FD） remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease. Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation. Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant. The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intdnsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management. Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to vadation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.
