Tissue trauma induced by lens fragmentation patterns in femtosecond laser assisted cataract surgery
Abstract:
To evaluate cumulative dissipated energy (CDE), laser time, central corneal thickness and endothelial cell loss after two different fragmentation pattern by means of femtosecond laser-assisted cataract surgery (FLACS). Eighty eyes of 80 patients that underwent FLACS were randomized in two groups: mixed chop and dice lens fragmentation pattern (group 1 with 40 eyes) and mixed chop and cylindrical lens fragmentation pattern (group 2 with 40 eyes). Cumulative dissipated energy was significantly lower in group 1 compared to group 2 (p<0.001). Postoperatively there was a decrement of endothelial cells count at the centre of the cornea in both groups compared with preoperative values with greater d...
Investigation on Phytochemical and Antioxidant Activity of the Plant Murraya koenigii Linn (Curry leaf) in Rajshahi, Bangladesh
Abstract:
The use of herbal medicine is becoming popular day by day due to toxicity and side effects of allopathic medicines. Considering the medicinal importance of the plant Murraya koenigii Linn (Curry leaf), the antioxidant activity (AC), total phenolic content (TPC), total flavonoid content (TFC), of different fractions of methanolic extract (DIA-ion resin adsorbed fraction, chloroform, Ethyl acetate and petroleum ether) of M. koenigii were investigated. Among the fractions, DIA-ion resin-adsorbed fraction showed the highest total antioxidant activity with absorbance 2.320±06 and petroleum ether fraction showed the lowest total antioxidant activity with absorbance 1.944 at 100 mg/ml concentration. The TPC were found range between 13.285 to 17.52 mg GAE/g while the highest amount of TFC recorded among the extracts was 16.65 mg CatE/g. DPPH free radical scavenging activity of different extracts of leaves was also measured where DIA-ion resin-adsorbed fraction had the hi...
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 (λem = 558 and λex = 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 (Kf) 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.
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...
