The elastic thickness parameter was estimated using the mobile correlation technique between the observed isostatic disturbance and the gravity disturbance calculated through direct gravimetric modeling. We computed the vertical flexure value of the crust for a specific elastic thickness using a given topographic dataset. The gravity disturbance due to the topography was determined after the calculation. A grid of values for the elastic thickness parameter was generated. Then, a moving correlation was performed between the observed gravity data(representing actual surface data) and the calculated data from the forward modeling. The optimum elastic thickness of the particular point corresponded to the highest correlation coefficient. The methodology was tested on synthetic data and showed that the synthetic depth closely matched the original depth, including the elastic thickness value. To validate the results, the described procedure was applied to a real dataset from the Barreirinhas Basin, situated in the northeastern region of Brazil. The results show that the obtained crustal depth is highly correlated with the depth from known models. Additionally, we noted that the elastic thickness behaves as expected, decreasing from the continent towards the ocean. Based on the results, this method has the potential to be employed as a direct estimate of crustal depth and elastic thickness for any region.

The X-linked adrenoleukodystrophy (ALD) is a severe neurodegenerative disorder due to mutations in the ABCD1 gene. Objective: To report a case of a 19-year-old man with adrenal insufficiency due to adrenoleukodystrophy. Method: Case report and literature review. Result: A previously healthy 19-year-old male patient was admitted to the emergency room with nausea and vomiting for 5 days, who progressed to abdominal pain, severe asthenia, and fever (38.5°C). He referred progressive darkening of the skin, oral mucosa, tongue and nail bed of the hands and feet, observed in the last 6 years. Emergency laboratory evaluation showed severe hyponatremia and hyperkalemia, which, together with decreased plasma cortisol, directed the investigation to causes of adrenal insufficiency. High ACTH (Adrenocorticotropic hormone) and very long chain fatty acid levels closed the diagnosis. Discussion: ALD is characterized by progressive demyelination in the central and peripheral nervous system and adrenal insufficiency consequence to the accumulation of very long chain fatty acids (VLCFA) in the adrenal. The overall incidence of ALD is 1:17,000. Adrenal insufficiency may be the first symptom of ALD in boys and adults. The diagnosis is based on the measurement of VLCFA plasma levels. Allogeneic bone marrow transplantation is the only treatment that provides a permanent cure when the procedure is performed at an early stage of brain demyelination, i.e. when patients are asymptomatic, although brain magnetic resonance imaging (MRI) is abnormal. Treatment of Addison’s disease is obligatory, but does not change the course of neurological symptoms.

The incidence of Mycobacterium avium complex pulmonary disease (MACPD) has been globally increasing. The present study aims to provide a comprehensive analysis of clinical characteristics and treatment response among patients in the Amazon region of Brazil and conduct a retrospective cohort study at a prominent referral hospital in the State of Par, Brazil, from 2012 to 2020. The M. avium group represented 58.9% of cases, followed by M. intracellulare (35.7%), M. colombiense (3.6%), and M. chimaera (1.8%). The majority of patients (73.2%) were female and with an average age of 63 years. Primary clinical manifestations included persistent cough and sputum production. The Charlson comorbidity index (CCI) averaged 2.47, with 36.3% of patients having a CCI score equal to higher than 3. Notably, over 70% of patients had received treatment for pulmonary tuberculosis before initiating treatment for MAC infection. The fibrocavitary radiologic form was the most prevalent (55.4%), frequently exhibiting a bilateral distribution (53.6%). Antimicrobial susceptibility revealed a significant prevalence of MAC resistance to drugs in the therapeutic regimen. despite this, most of the patients experienced clinical improvement (50%). In conclusion, this study highlights a higher prevalence of MAC infections among middle-aged women, with a history of pulmonary tuberculosis treatment and presenting the fibrocavitary radiological form was predominant.

Biodiversity of Arbuscular Mycorrhizal (AM) fungi in mangroves of Goa in West India

引用

Journal of Forestry Research 2013年第3期24卷 515-523页

作者： James D'souza Bernard Felinov rodrigues department of Botany Goa UniversityGoa 403 206 India

Seventeen mangrove species of eight families at seven river- ine and fringe habitats in Goa West India were surveyed for Arbuscular Mycorrhizal （AM） fungal diversity. Sixteen species were found to be mycorrhizal and one species showed no AM fungal colonization. AM root colonization was recorded at all seven sites and ranged from 6%-77%. Maximum root colonization was recorded in Excoecaria agal- locha （77%） and minimum colonization in Avicennia marina （6%）. Paris-type colonization was predominant at all sites. Auxiliary cells were recorded in roots of Acanthus ilicifolius, Ceriops tagal and Sonneretia alba. AM fungal root colonization and spore density varied by plant species and site. Site average spore density ranged from 1.84 spores.g^-1 to 0.54 spores.g-1 of soil. In total, 28 AM fungal species of five genera, viz. Glomus, Acaulospora, Scutellospora, Gigaspora and Entrophospora, were recovered. Glomus was the dominant genus, three species of which were sporocarpic forms. Maximum site species richness （SR） ranged from 16 to 5. Species richness was maximum in A. ilicifolius where seven species of three genera were recovered. Based on relative abun- dance （RA） and isolation frequency （IF）, two common species, viz. G. intraradices and A. laevis, were recovered from all seven sites.

AIM:To evaluate the sensitivity and specificity of abdominal ultrasound (US) for the diagnosis of hepatic steatosis in severe obese subjects and its relation to histological grade of steatosis. METHODS: A consecutive series of obese patients, who underwent bariatric surgery from October 2004 to May 2005, was selected. Ultrasonography was performed in all patients as part of routine preoperative time and an intraoperative wedge biopsy was obtained at the beginning of the bariatric surgery. The US and histological findings of steatosis were compared, considering histology as the gold standard. RESULTS: The study included 105 patients. The mean age was 37.2 ± 10.6 years and 75.2% were female. The histological prevalence of steatosis was 89.5%. The sensitivity and specificity of US in the diagnosis of hepatic steatosis were, respectively, 64.9% (95% CI: 54.9-74.3) and 90.9% (95% CI: 57.1-99.5). The positive predictive value and negative predictive value were, respectively, 98.4% (95% CI: 90.2-99.9) and 23.3% (95% CI: 12.3-39.0). The presence of steatosis onUS was associated to advanced grades of steatosis on histology (P = 0.016). CONCLUSION: Preoperative abdominal US in our series has not shown to be an accurate method for the diagnosis of hepatic steatosis in severe obese patients. Until another non-invasive method demonstrates better sensitivity and specificity values, histological evaluation may be recommended to these patients undergoing bariatric surgery.
