Eco-Friendly Tamarind Kernel Thickener for Printing of Polyester Using Disperse Dyes
Harshita Chaudhary,Vinita Singh 한국섬유공학회 2018 Fibers and polymers Vol.19 No.12
Printing is a form of dyeing in which colors are applied to specified regions instead of the entire fabric. To restrict the coloring matter to the design area, the dyes and other auxiliaries are pasted with a natural or synthetic thickening agent. Finding alternatives to the used thickeners has gained importance lately due to the several limitations associated with toxicity, availability, and cost of the currently used thickeners. Tamarind kernel powder has the potential to be explored as a textile thickener whilst providing economic benefits. Tamarind kernel, derived from the seeds of Tamarindus indica Linn., is a byproduct of the tamarind fruit and pulp industry. It is a low cost, non toxic, biodegradable, cold water soluble thickener. In the present study, an effort has been made to explore the suitability of tamarind kernel thickener for printing of polyester using disperse dyes. On the basis of the qualitative and quantitative analysis, 25 % concentration of tamarind kernel powder, steaming temperature of 130 oC for 30 min with carrier was optimized as printing conditions. The samples printed using the given conditions exhibited brighter and sharper lines with uniformity of color. No change in whiteness of the ground and handle of the fabric was seen. Haloing and flushing was observed in samples printed with lower concentrations (5-15 %) of tamarind kernel thickener. Color value (K/S) of the samples was increased with increase in steaming time and temperature indicating better fixation of dye at high temperatures. All the printed samples irrespective of the varying thickener concentration, steaming time and temperature gave excellent fastness to washing and rubbing.
Infective Lesions in Lung in Mantle Cell Lymphoma

Introduction Mantle cell lymphoma (MCL) constitutes 2-10% of Non Hodgkin Lymphoma. It is a B-cell neoplasm, composed of small to medium sized cells. Short Clinical History A 55/ F presented with progressive painful swelling in neck & bilaterally enlarged tonsils for 1 year. No hepatosplenomegaly or B- symptom was seen. Hemogram was normal. Bone Marrow (BM) examination and biopsy showed no lymphoma infiltration. PET-CT showed generalized lymphadenopathy involving cervical, supra & infra-diaphragmatic & pelvic regions. In Chest nodular opacities were seen in both lower lobes and in anterior & inferior segment of left upper lobe (8 mm size). No pulmonary parenchymal lesion with increased FDG uptake was seen. Liver was enlarged with fatty changes. NHL was suggested. Lymph node biopsy showed infiltration by large lymphocytes, positive for CD20, CD5, BCL-2, Cyclin D and negative for CD3, CD10, BCL6, MUM1, CD23. Proliferation marker for Ki 67 was 50%. MCL stage 4 was advised. Viral markers were negative. After 6# RCHOP, clinical & radiological remission was seen. ASCT was refused by the patient. Repeat CT scan was normal. PET-CT showed physiological FDG uptake in myocardium. No abnormal FDG uptake was seen in lungs, mediastinum or thoracic wall. Lungs airways, pleura, heart, vessels and other mediastinal structures were normal. After these 10 doses of maintenance therapy with Rituximab patient is performing well and spent treatment free for last one & half year with MIPI 3. Discussion & Conclusion Nodular lesions in lungs seen prior to therapy were subsided now, which may be of infective origin. A careful monitoring of lung nodule is must in a case of MCL. Lung involvement is not uncommon with NHL, but it is rare for mantle cell lymphoma to involve the lung parenchyma.

In the recent past decade, layered bismuth metal oxides (Bi2MO6, M = W, Mo and Cr) have establishedsubstantial consideration comparable to bismuth oxyhalides (BiOX, X = Cl, Br, I and F) for its emergingpotential towards its photocatalytic applications in clean energy production and environmentalremediation. Their electronic band structure characterises appropriate band-gap for visible lightphotocatalytic activity. The photocatalytic activities of these materials can be deliberately incrementedusing various strategies including formation of heterojunction, modification of interface, usingsensitizers, metal and non-metal doping, development of composites, and formation of oxygenvacancies. Nevertheless, its visible light applications limit up due to higher recombination ofphotoinduced charge carriers. This review systematically encapsulates electronic spectra, strategiesimplemented for higher separation of charge carriers, and establishing its potential in thefield of cleanenergyproduction as well as degrading manageable and recalcitrant pollutants. Finally, the currentscenario and future aspects of using Bi2MO6 photocatalysts are summarised.
Palatal rhinosporidiosis: an unusual case report and review of the literature
Putthia, Harshita,Manjunatha, Bhari Sharanesha,Astekar, Madhusudan,Taufiq, Samreen The Korean Association of Oral and Maxillofacial S 2018 대한구강악안면외과학회지 Vol.44 No.6
Rhinosporidiosis is a chronic, granulomatous, mucocutaneous infection caused by Rhinosporidium seeberi. The infection is non-contagious and sporadic in humans. The site most commonly affected is the mucous membrane of the nose and nasopharynx, followed by the oropharynx, trachea, bronchi, ear, eye, and genitourinary tract. It can also spread to other areas through blood and lymph. Here, we report a case of rhinosporidiosis affecting the palate in a 60-year-old female patient.
Evaluation of Pulmonary Nodule in Mantle Cell Lymphoma

Introduction Mantle cell lymphoma (MCL) is an aggressive non-Hodgkin lymphoma (NHL) with median survival 3 -4 years from diagnosis. Method A case was retrieved from Hospital Record. Short Clinical History A 64 year old male presented with generalized lymphadenopathy. Hemogram showed TLC 12200/ cmm with 70% lymphoid cells in blood smear. Bone marrow (BM) aspirate smear showed 70% abnormal lymphoid cells, which was supported by biopsy (CD20+, CD3-). Viral markers were negative. Lymph node biopsy showed lymphoid cell positive for CD20, CD5 & Cyclin D and negative for CD3 & CD23; indicating MCL. Management with 6 # Bendamustine & Rutiximab resulted into clinical and hematological improvement. After 17 months of treatment free interval (TFI), he presented with Peripheral Neuropathy Grade -III, with no hematological or radiological abnormality. Pregabalin was advised. Again after 2 months (19 months of TFI) he presented with left inguinal lymphadenopathy. Biopsy from lymph node as well as BM showed abnormal lymphoid cells positive for CD20, CD5 & Cyclin D and negative for CD3, CD23, CD10 & BCL-6, MCL relapse was suggested. After 3 # CHOP type II Diabetes was detected. After 6 # CHOP chemotoxicity like fever, cough, vomiting, mucositis, oral ulcer etc. were noticed, which were managed conservatively along with Linalidomide and Prednisolone. Follow up x-ray & HRCT showed nodular lesions in right upper/ mid lobe; therapy for pulmonary Tuberculosis was started. Later he presented with painless and gradually increasing swelling in left thigh, for which radiotherapy showed partial relief. Doppler study for the cause of thigh swelling suggested a partial thrombus in left proximal Great saphanous vein, Lenalidomide induced Dddep vein thrombosis was considered, which was managed with anticoagulants. The case expired after some days. Conclusion Relapsed MCL cases are prone to develop Tuberculosis in developing countries leading to death.
