A New Spectrofluorimetric Approach for The Quantitation of Imipramine Hcl in Commercial Dosage Forms

Abstract:

A spectrofluorimetric method has been developed for the determination of imipramine HCl in bulk and commercial dosage forms. The method was based on measuring the fluorescence emission intensity of imipramine-eosin Y ion pair complex (λ_em = 558 and λ_ex = 319) in dichloroethane at buffer solution (sodium acetate and acetic acid) of pH 4.8. The stoichiometric ratio between imipramine and eosin Y was studied by Job's method of continuous variations and found to be 2:1. Formation constant (K_f) and Gibb’s free energy change (ΔG) were calculated and pointed towards the spontaneous nature of the reaction. A series of variables were studied to optimize the reaction conditions. The proposed method was validated as per ICH guidelines and successfully applied for the determination of active imipramine HCl in commercial dosage forms with high degree of accuracy and precision.

Atypical Patterns of Constrictive Pericarditis after Heart Transplantation: A Case Report

Abstract:

Constrictive pericarditis (CP) represents a rare complication after heart transplantation (HTx), resulting from various postoperative events such as mediastinitis, pericardial effusion, or allograft rejection. We describe our recent experience with managing an HTx recipient who developed atypical patterns of CP predominantly involving the right ventricle. A 52-year-old male who had received heart transplantation 2.5 years before was admitted to our institution because of progressive symptoms of heart failure. The patient had experienced acute rejection twice post-HTx, both with International Society for Heart and Lung Transplantation grade 1R, undergoing an additional endomyocardial biopsy other than those performed during regular check-ups. On admission, echocardiography revealed paradoxical septal motion and a large cystic-like mass with a thick capsule in front of the right ventricle. Right heart catheterization revealed elevation of right atrial pressure, with...

Title - Case of Unilateral Congenital Aural Atresia & Microtia with Cholesteatoma

Abstract:

We report a case of cholesteatoma associated with unilateral congenital aural atresia (CAA) and microtia, resulting in extracranial complication. A 13-year-old girl presented with right ear purulent discharge from pre and post auricular area with mastoid tenderness. On clinical examination, she had right grade II microtia with pre-auricular skin tag and healed scar tissue in periauricular region. On High Resolution Computerized Tomography (HRCT) scan of temporal bones, there was CAA of right ear with extensive cholesteatoma in middle ear cleft. The cholesteatoma was subsequently removed by radical mastoidectomy with uneventful post-operative period. Cholesteatoma associated with CAA may remain undiagnosed in early childhood resulting in life threatening temporal and intracranial complications.

A Study on Contagious Bovine Pleuropneumonia in Khartoum State, Sudan

Abstract:

The study was carried out to investigate the occurrence of contagious bovine pleuropneumonia CBPP in Khartoum state. One-hundred twenty-two pneumonic lung tissue samples were collected from different slaughterhouses (116 samples most of which from local breed cattle) and from the field (six samples from cross breed cattle). Two-hundred and fifty-seven serum samples were collected randomly from cattle in different areas of the state. Tissue samples were cultivated using the standard mycoplasma procedures. Mmm was isolated from three pneumonic lungs collected from the field while no isolates were recovered from slaughterhouse samples. Histopathological sections from the positive samples revealed the typical picture of the CBPP which include fibrinonecrotic pneumonia within filtration of inflammatory cells and fibrin and distention of interlobular septae. One hundred and eight out of 257 serum samples were found positive for antibodies against Read Article

Recurrent branch retinal arterial occlusions associated with plasminogen activator inhibitor-1 mutation

Abstract:

A 57-year-old Hispanic female presented with 3 days of blurry vision in the left eye. Eight years prior, she had a branch retinal artery occlusion in the right eye and a hematologic work-up revealed a 4G/4G polymorphism in plasminogen activator inhibitor-1. With the current episode, she was found to have bilateral branch retinal artery occlusions and mild vitritis in the left eye, simulating a toxoplasma infection. An infectious and inflammatory work up, however, was negative and the vitritis resolved after a short course of steroids. Plasminogen activator inhibitor-1 mutations may be associated with an increased risk of retinal vascular occlusions.

Assessment of the Immune Response Induced in Neonatal Calves by Vaccination with Mycobacterium Bovis BCG Phipps Under Field Conditions

Abstract:

Immunization of cattle with the bacillus Calmette-Guérin (BCG) vaccine, especially neonates, induces protection against Mycobacterium bovis (M. bovis) and has been proposed as a strategy for bovine tuberculosis (bTB) control. Therefore, the aim of this study was to evaluate the immune response induced under field conditions in neonatal calves vaccinated with BCG Phipps, a strain that has rarely been evaluated in the bovine population, using interferon (IFN)-γ and tuberculin tests, flow cytometry and enzyme-linked immunosorbent assay. Two groups (vaccinated and control) of 5 calves were monitored for 12 weeks, and increases in the in vitro IFN-γ production, the percentage of cluster of differentiation (CD)8+ T cells and the activation levels of CD4+ and CD8+ T cells were observed 3 to 4 weeks post-vaccination. Bovine purified protein derivative-specific IFN-γ production was increased about 4.8- and 5.5-fold in vaccinated animals compared to non-vaccinated a...

Natural Infection by H1-Like Influenza a Virus in South American Camelids from Argentina: Serological Evidences.

Abstract:

Serum samples from wild and domestic South American Camelids (SAC) from Argentina, collected before (2008), during (2009) and after (2010) the 2009 H1N1 influenza pandemic were tested by hemagglutination-inhibition assay (HIA) to evaluate the seroprevalence of antibodies (Ab) against different subtypes of influenza A viruses: A(H1N1)pdm09, A/sw/Argentina/SIV/2009(H3N2) and A/eq/Argentina/97(H3N8). For A(H1N1), an ELISA using a recombinant H1-hemmaglutinin from a reference strain (HA0 PuertoRico/8/1934) was also conducted. Serum samples from Guanacos (126), vicugnas (21) and llamas (100) from Jujuy, Mendoza and Río Negro provinces were analyzed; no clinical signs of respiratory disease were detected, reason for which no nasal swabs were obtained. No seropositive reactors to H3N2 nor H3N8 variants were detected, nevertheless high incidence of Ab reactive to A(H1N1)pdm09 were found by HIA; results which were confirmed by ELISA. The Ab seropositive animals to H1-like...

The Effects of Artificial Turf on the Performance of Soccer Players and Evaluating the Risk Factors Compared to Natural Grass

Abstract:

The global popularity of soccer has led to widespread tendency towards this sport. Because of the convenience of using artificial surfaces, the rapid growth of using these surfaces led to concerns about the declining performance of the players. The aim of this comprehensive review is to study the difference between the performance of players on different playing surfaces and the risk factors for use of artificial turf compared to natural grass. A literature search of valid scientific databases such as Science Direct, PubMed and Jstor by searching keywords was performed. In total, more than 6,000 articles were retrieved. After the preliminary selection process, the final analysis was performed on a total of 76 articles.

Markers for Significant or High-Grade Prostate Cancer in Patients over 75 Years Undergoing Prostatic Biopsy

Abstract:

To show the increased necessity of routine prostate biopsy in men older than 75 years and to identify markers, which reliably indicate the presence of a prostate cancer (PCa), we evaluate several different parameters from elderly patients.
