The present study was performed in order to discern the effects of combined exposure to cadmium and mercury on liver function and histopathological alterations in male adult Wistar rats. In the present investigation, cadmium (100 mg/l) and mercury (25 mg/l) were administered orally for 10 weeks separately or in combination. The rational for studying cadmium and mercury is that both of these metals are encountered frequently in the same contaminated areas. In liver, the activities of serum alanine aminotransferase (ALT) and aspartate amino tranferase (AST) increased significantly in the cadmium (Cd) and mercury (Hg) alone or in combination (Cd + Hg) compared to the control suggesting that both cadmium and mercury cause hepatotoxicity spatially when co-administrated. We noted an increase in serum lactate dehydrogenase (LDH) activity in Cd and combined Cd + Hg treated groups while it decreased in Hg treated group. There was no statistically significant change in the level of total bilirubilin. Serum urea concentration showed a significant increase in the Cd and Hg groups compared to the control group. However an increase in serum creatinine concentration was noted only in the combined treated rats showing that renal insufficiency is more serious in the co-exposed group. Light microscopic examination indicated severe histological changes in the two organs under Cd and mercury influence. Results of the present investigation clearly showed that mercury has profound effects of hepatic handling of cadmium (synergistic effect) as shown by histological and biochemical results. Moreover, we observed a antagonist effect between these two toxic metals on kidney markers such as urea.

Thymomas are the most common neoplasms of the mediastinum. It is common that thymoma invades neighboring structures in the thorax, but direct polypoid tumor growth into the airway is extremely rare. We report a rare case of invasive thymoma with polypoid endobronchial growth in a 66-year-old woman. Computed tomography demonstrated an anterior mediastinal tumor which extended into the right upper lobe. Endoscopic examination revealed a polypoid tumor which occluded the right upper bronchus. A biopsy specimen obtained from the intraluminal mass was very suggestive of thymoma. The patient had no parathymic syndrome. The tumor was resected with the right upper lobe. The final post-operative tissue findings confirmed a type B2 thymoma of the World Health Organisation classification.

The first report of new 3-(tetrazol-5-yl)-2-iminocoumarin derivatives is described. The title compounds were prepared in two steps and were obtained in good yields (55-93%). They have been fully characterized by 1H, 13C NMR, FTIR, UV-Visible and HRMS. They were tested for their antiproliferative activities against six representative human tumor cell lines (Huh 7-D12, Caco2, MDA-MB231, HCT 116, PC3 and NCI-H727) and HaCat keratinocytes. Among them, compound 5e was active on HCT 116 (IC50 15 μM).

Introduction: The high resolution computed tomography (HRCT) is an important part in the diagnostic approach of interstitial lung disease (ILD) associated with connective tissue diseases (CTD) by providing detailed information on the elementary lesion and the radiological pattern of ILD. Aim: to point out the role of HRCT in the diagnosis of ILD associated with CTD (ILD-CTD). Methods: A Retrospective descriptive study was conducted between 2008 and 2017. Data of 24 patients presenting ILD-CTD were collected. A review of HRCT was performed by a radiologist without knowledge of the CTD. Results: Predominant elementary lesion of ILD associated with dermatomyositis (9 cases) was ground glass opacity (n = 9) followed by consolidation (n = 6). Non Specific Interstitial Pneumonia (NSIP) was the most reported pattern (5 cases). Ground glass opacity was also the predominant elementary lesion for the 2 cases of scleroderma and in Sjögren’s syndrome (4 cases/5). NSIP was the predominant radiological presentation in these two CTD. Lymphoid interstitial pneumonia revealed Sjögren’s syndrome in one case. In rheumatoid arthritis (6 cases), the elementary HRCT lesions were irregular interlobular septal thickening (n = 4) and honeycombing (n = 4) consistent with Usual Interstitial Pneumonia (UIP) in 2 cases. Similarly UIP has been described for the 2 patients with lupus and mixed connective tissue disease. Conclusion: HRCT plays an important role in the management of ILD-CTD. Description of the HRCT elementary lesions and the radiological pattern of ILD can be helpful for CTD’s diagnosis.

A rigorous full wave technique based on the Transverse Wave Concept Iterative Procedure (WCIP) is used to design a complex Frequency Selective Surface (FSS). These surfaces include a periodically arrangement of identical circuit. There are used as filters and reflector antenna as well as deep-space exploration for multi-frequencies operations. A simple FSS structure is studied in the first stage to validate our approach. In the second stage two different complex structures are studied. The good agreement between simulated and published data justifies the design procedure.

Objective: To investigate the protective effects of Aristolochia longa (A. longa) and Aquilaria malaccensis (A. malaccensis) on acute hepatotoxicity induced by lead in female albino rats. Methods: Twenty five (25) apparently healthy female Wistar rats were randomly divided into five groups of five rats in each: control, Pb, Pb + A. longa (Ar), Pb+ A. malaccensis (Aq), and Pb+ A. longa (Ar) + A. malaccensis (Aq) lead (100 mg/kg b.w.) as Pb (C2H3O2)2 added in their drinking water for 75 days. A. longa (rhizome powder at a dose of 10 g/kg of diet ) and A. malaccensis (heartwood powder at a dose 10 g/kg of diet) were added to the feed during the last 15 days of lead exposed in the animals. Results: Obtained results revealed that lead treatment caused a significant increase in serum GOT, GPT and ALP activities and in liver of MDA level and CAT activity. In contrast, it led to an decrease in the liver GOT, GPT and GST activities and in GSH level in rats. Also, the results clearly showed that lead causes alterations of hepatic tissue in comparison with controls. Our results showed that treatment with A. malaccensis and A. longa a partial correction of the previous parameters. The histological observations confirmed the hepatoprotection results by the biochemical parameters. Conclusions: Results demonstrated beneficial effects of A. longa and A. malaccensis treatment in Pb-induced oxidative stress and tissue damage in liver.

The wave iterative method is a numerical method used in the electromagnetic modeling of high frequency electronic circuits. The object of the authors’ study is to improve the convergence speed of this method by adding a new algorithm based on filtering techniques. This method requires a maximum number of iterations, noted Nmax, to achieve the convergence to the optimal value. This number will be reduced in order to reduce the computing time. The remaining iterations until Nmax will be calculated by the new algorithm which ensures a rapid convergence to the optimal result.

Introduction: Apart from its increasingly important frequency, occupational asthma (OA) has become the most important cause of occupational respiratory disorders in developed countries. The number of etiological agents continues to grow following the constant introduction of new harmful substances in industry. Objectives: Determine the prevalence and incidence of OA in our country, the socio-occupational characteristics of asthmatics, and study the forensic and social impact of such pathology. Material and Methods: An exhaustive retrospective epidemiological study was conducted in Tunisia about charts of occupational asthma cases recognized by the competent commissions of the National Medical Care Fund (CNAM) during the period ranging from January 1st 2000 to December 31st 2008. Results: 361 occupational asthma cases, accounting for a prevalence of 7.17% of all occupational diseases, were recognized during the period of the study. Occupational asthma annual incidence was estimated to be 24.42 cases per 1000000 workers. Our study population was mainly women with a sex ratio of 0.86. More than a half (57.6%) of recognized OA cases were working in the textile industry sector. Concerning the asthmatics’ professional career, most of recognized OA cases (n = 225 i.e. 70.6% of cases) kept their jobs, whereas 58 patients did not. The professional career was linked to gender with a job loss that is 1.79 time more important in asthmatic women. Conclusion: The incidence of occupational asthma in Tunisia is comparable with that found in other Mediterranean countries. A rigorous and adequate prevention is necessary and allows reducing the importance of this occupational pathology and its serious consequences.
