Journal of Basic and Clinical Pharmacy , 2012,
Abstract: The incidence of infections due to extended-spectrum β-lactamase (ESBL)–producing Escherichia coli has been increased dramatically in recent years. Treatment is difficult because of frequent multidrug resistance. To identify the sensitivity of commonly used antibiotics, 36 ESBL producing E. coli strains were isolated from young adult female patients in a govt. medical college hospital in Bangladesh. The samples were studied for antimicrobial sensitivity against nine (9) commonly used antibiotics namely ampicillin (amp), trimethoprim-sulfomethoxazole (tms), tetracycline (tet), ciprofloxacin (cip), mecillinum (mel), ceftriaxone (cef), nalidixic acid (nal), Azithromycin (azm) and Chloramphenicol(chl) and the MIC values were determined by agar dilution method. Overall, 72% of the strains were multidrug resistant (MDR) i.e. resistant to two or more drugs. Among 36 strains, 14 isolates were initially found to be resistant against third generation cephalosporin, ceftriaxone. Those were subjected to the test for production of ESBL (Extended Spectrumβ-Lactamase) and 7 showed positive results.
Evaluation of Phytoremediation Potential of Catharanthus roseus with Respect to Chromium Contamination  [PDF]

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.515251

A major environmental concern due to dispersal of industrial and urban wastes generated by human activities is the contamination of soil. The release of heavy metals into the terrestrial ecosystem is a major problem. Accumulation of heavy metals in environment and particularly in soil is a serious environmental concern, as the accumulated heavy metal ions can find their way into living organisms via contamination of ground water or food chain. This praxis urgently requires and demands governmental regulations in India. Two samples of sludge were collected from Banthar Industrial Pollution Control Company (BIPCC), UP State Industrial Development Corporation (UPSIDC), Leather Technology Park, Banthar, Unnao, India. In the present study, the phytoremediation potential of Catharanthus roseus, a valued medicinal plant, with respect to chromium has been analyzed. C. roseus was shown to absorb up to about 38% of the amount of Cr present in primary and secondary sludge amended soil through roots and accumulate it to about 22% in leaves. Effect of chromium concentration on the status of antioxidant enzyme peroxidase (POD) and detoxification enzyme glutathione-S-transferase (GST) from C. roseus leaves was also observed and determined. Increased expressions of POD and GST were observed on native PAGE under stress conditions as compared to control. C. roseus can well tolerate low amounts of chromium (and accumulate it to about 22% in leaves) and can, thus, prove useful in the reclamation and remediation of chromium contaminated soil and land.

Iqbal. Husain, Rumana. G. Mattoo
Communications and Network (CN) , 2010, DOI: 10.4236/cn.2010.22021
Abstract: A multiobjective variational problem involving higher order derivatives is considered and optimality condi-tions for this problem are derived. A Mond-Weir type dual to this problem is constructed and various duality results are validated under generalized invexity. Some special cases are mentioned and it is also pointed out that our results can be considered as a dynamic generalization of the already existing results in nonlinear programming.

Abstract: Historical controversy and lack of controlled clinical trial study comparing the effects of sodium fluoride and calcitonin therapies in osteoporosis of patients with RA made us to conduct this study to clarify which one of the above treatments would be more useful and effective in the treatment of osteoporosis.From subjects who turned to Ahwaz Rheumatoid Arthritis Clinic during 2000, all women who met the American College of Rheumatology (ACR) 1987 criteria for RA (7), WHO 1994 criteria for osteoporosis (8) and signed the written consent were enrolled into the study. Considering these inclusion criteria, 70 women were enrolled into the study. They were randomized into two groups. Age, BMI (body mass index) and BMD (bone mineral density) were the adjusted variables during randomization. Thirty-four patients were treated with 20 mg sodium fluoride daily and 36 patients with 200 units nasal calcitonin per day. All patients were treated for 12 months.Patients who received Fluoride showed significant higher BMD in femoral neck (0.74 vs. 0.65, p<0.01) and in lumbar spine (0.90 vs. 0.79, p<0.05) than who received calcitonin after 12 months of therapy.

Abstract: Separate treatment of high-nutrient sidestream is an efficient and cost effective way to decrease the loading on the main plant, resulting in lower effluent nutrient concentration. This study investigated the use of a combined forward osmosis-membrane distillation (FO-MD) system for the removal of nitrogen present in high concentration in sidestream from anaerobic digestion process. The combined system was able to achieve almost 100% rejection of solids and acetic acid, and more than 98% rejection of NH3-N from the sidestream. The high rejection of NH3-N was mainly achieved by the FO process. The solids in the feed solution contributed to fouling problem in both FO and MD, resulting in significant decline in flux. However, 76% or higher flux recovery was achieved for FO membrane by cleaning with tap water. We observed that flux recovery was due to removal of solids from the membrane surface by the cleaning process. FO membrane also demonstrated excellent performance for continuous operation when cleaned for 15 min in every 24 h interval. Overall, the combined FO-MD system was found to be an effective solution for treatment of nutrient rich sidestream.

Abstract: This article reports massive right-sided hemorrhagic pleural effusion as the sole manifestation of pancreatitis in a 16-year-old Iranian boy. The patient referred to Nemazee Hospital, the main hospital of southern Iran, with right-sided shoulder and chest pain accompanied with dyspnea. His chest x-ray showed massive right-sided pleural effusion. The pleural fluid amylase was markedly elevated (8840 U/L), higher than that in the serum (3318 U/L). Abdominal CT scan showed a cystic structure measuring about 5·2 cm in the head of pancreas, highly suggestive of a pancreatic pseudocyst. Pleural effusion resolved after 3 weeks of chest tube insertion but not completely. After this period of conservative therapy another CT scan showed that pseudocyst was still in the head of pancreas. So, external drainage was done with mushroom insertion and the patient was discharged after 40 days of hospitalization. The cause of pancreatitis could not be identified.Pancreatitis should be taken into consideration when hemorrhagic pleural effusion, especially in the right hemithorax occurs.Hemorrhagic pleural effusion, especially in the right hemithorax, rarely occurs as the sole manifestation of pancreatitis [1-6]. Most cases of hemorrhagic pleural effusion secondary to pancreatitis are between the ages of 20 to 55, and patients are alcohol drinkers [2,5]. This article reports massive right-sided hemorrhagic pleural effusion as the sole manifestation of pancreatitis in a 16-year-old Iranian boy.This 16-year-old boy, from a village in Fars Province, Southern Iran, developed left paraumblical (sometimes epigastric)abdominal pain with moderate intensity about five months prior to admission. The pain subsided after three months. However, 20 days later, the patient developed right-sided shoulder and chest pain accompanied with dyspnea. The patient's severe shoulder pain was mismanaged by a physician who considered it musculoskeletal pain. The patient then referred to Nemazee Hospital, the main

Abstract: A novel design approach for erbium-doped fiber amplifiers is proposed based on particle swarm optimization algorithm. The main six parameters of the EDFAs including: pumping wavelength, input signal power, fiber numerical aperture, erbium-doped area radius, erbium concentration, and the fiber length are optimized utilizing a fast and efficient method called particle swarm optimization algorithm. In this paper, a combination of fiber amplifier bandwidth, gain, and flatness are taken into account as objective function and the results are presented for different pump powers. Our investigation shows that particle swarm optimization algorithm outperforms genetic algorithm in convergence speed, straightforwardness, and coping with highdimensional spaces, when the parameters of EDFA are to be optimized. It has been shown that the required time for the optimization of the fiber amplifier parameters is reduced four times by using particle swarm optimization algorithm, compared to genetic algorithm method.

Abstract: Background and Aims: Viruses might be one of the causes that trigger systemic lupus erythematosus (SLE). Steroid therapy may influence the natural history of virus infections. Reports on the association between SLE and hepatitis C virus (HCV) infection are scarce. We conducted a study to investigate the prevalence and clinical significance of HCV infection in patients with SLE. Methods: In a prospective study (2003-2005) we evaluated the prevalence and clinical significance of chronic HCV infection in patients who met the diagnostic criteria of the American College of Rheumatology for SLE. The blood samples of 124 patients were tested for HCV antibodies by an enzyme-linked immunosorbent assay (ELISA). Anti-HCV reactive samples were retested for confirmation by Abbott MATRIX Immunoblot assays and also for HCV-RNA detection by the polymerase chain reaction (PCR). The control group consisted of first time blood donors referred to the regional blood transfusion organization.Results: Six of 124 (4.8%) patients were seropositive for anti-HCV by ELISA; of these only 3 cases (2.4%) were positive by PCR. Both ELISA and the Immunoblot assays may be falsely positive for ongoing HCV infection in patients with SLE. A 2.4% prevalence of active HCV infection was found in patients with SLE, which did not differ significantly from the prevalence of HCV in the general population (less than 1%). In the few positive cases, we observed no adverse influence of this infection on the clinical features of the systemic lupus erythematosus.Conclusions: Our results do not support the participation of HCV infection in the pathogenesis of SLE.

Abstract: Introduction: Systemic Sclerosis is a chronic, multisystem disorder of unknown etiology, characterized clinically by thickening of the skin caused by accumulation of connective tissue, and by involvement of visceral organs, such as GI tract, lung, heart, kidney and musculoskeletal system. Osteoporosis is a complication of this disease that was evaluated in this study. Material and Methods: This study was conducted to estimate the density of lumbar spine (L2-L4) and femoral neck among the patients with scleroderma and control group. On the basis of physical examination and history, none of the control group had risk factor for osteoporosis. 55 scleroderma female patients (mean age 39/09) were selected randomly and 56 healthy females (mean age 31/51) were selected as the control group. We measured bone mineral density (BMD) with dual energy x ray absorptiometry (DEXA). Results: The mean BMD of lumbar spine (L2-L4) was 0/79 gr/cm2compared to mean of 0/93 gr/cm2of the control group. The mean of femoral neck BMD was 1/02 gr/cm2compared to mean of control group with 1/15 gr/cm2. Both results were significant (P<0.05). Conclusion:The result of this study showed reduction of femoral neck & lumbar spine (L2-L4) BMD and this reduction was more significant in the lumbar spine (L2-L4).
