PREPARATION AND CHARACTERIZATION OF MICROPARTICULATE SYSTEM OF PROPRANOLOL HYDROCHLORIDE

Albumin microspheres (AMS) have found many applications in the diagnosis and treatment in recent years and more than 100 diagnostic agents and drugs have been incorporated into AMS. In the present study Bovine Serum Albumin (BSA) based microspheres bearing propranolol hydrochloride were prepared by an emulsion-internal phase stabilization technique. The prepared microspheres were studied for particle size distribution, drug loading, release characteristics, bioadhesion and in-vitro controlled diffusion across the rat intestine. The microspheres had mean diameters between 1-25 µm of which more than 50 percent were below 5 µm. The encapsulated drug was found to be about 9% w/w of that initially added to microspheres and the superficial drug was 25% of the total amount of the encapsulated drug. Also AMS were noted to possess good bioadhesion in such a way that about 70% of microspheres remained adherent on the surface mucosa of rat jejunum. The drug release from albumin microspheres was mainly controlled by diffusion and showed a biphasic pattern with a high initial release (burst effect), followed by a more gradual terminal release. The total amount of drug released from microspheres after 12h was 70%. In-vitro experiments on the rat intestinal segments revealed that the microspheres could effectively pass their content through intestinal membrane. Â

Expanding the Indication for Novel Theranostic 177Lu-Dotatate Peptide Receptor Radionuclide Therapy: Proof-of-Concept of PRRT in Merkel Cell Cancer

The field of theranostics is a new nuclear medicine tool being utilized in the treatment of different types of cancers. It couples receptor-specific based imaging predicting and guiding response to receptor-specific based radionuclide therapies. For example, somatostatin-receptor based imaging (Gallium; 68Ga-dotatate scan) is now predicting and guiding the use of treatment with the somatostatin-receptor radiolabeled somatostatin analog (peptide receptor radionuclide therapy PRRT – Lutetium; 177Lu-Dotatate) for neuroendocrine tumors that express the somatostatin receptors. The United States Food and Drug Administration approved the use of 177Lu-Dotatate PRRT for somatostatin-receptor-positive gastroenteropancreatic neuroendocrine tumors only. Here we show proof of concept and results of an outstanding response to this novel therapy in conjunction with immunotherapy in a refractory cancer type where it has not been approved (Merkel Cell Cancer). Our results and data provide proof of principle for considering the use of this novel therapy in a tumor-agnostic approach; similar to approval of immunotherapy for mismatch repair deficient tumors. The response demonstrated has also been unprecedented, likely secondary to use of PRRT with immunotherapy. These observations have profound and broad implications on how to move this novel field of theranostics forward for treatment of many cancer-types

Net zero pole streets light by solar PV module

People have started to move non-conventional energy source. The energy generated from non-conventional energy source should be used in effective manner. It is also eco-friendly and viable for the environments. The solar street light is an innovation take for the sustainable growth through many policies like make in India. This paper proposes a net-zero pole streets lighting by solar PV module and the mean of net-zero is that no power demand from the grid. The proposed system consists of a PV panel, LEDs lamp, and micro-inverter. In this project we have used LEDs lights due to many advantages as compare to other lamps. This LEDs lighting is very efficient (very high efficiency) and cost effective (long life). In additional in this project we used micro-inverter. This micro-inverter is converted DC supply from the PV module into AC supply and its AC supply is feed to the grid through a net-meter. In this project battery is not required

Review on Calotropis Gigantea as a Topically used Plant

There have been numerous reports of the Asclepiadaceae plant, Calotropis gigantea R.Br, having medicinal and other uses. Plants have been employed as a source of medicinal substances since ancient times. In the indigenous system of medicine, plants are used extensively to treat disease. Traditional medicine makes use of various plant extracts or bioactive substances. This kind of research offers health at a reasonable price. The findings imply that the stem, leaves, and flower's phytochemical qualities can be used to treat a variety of diseases. The nation that produces the most medicinal herbs is India, which is fittingly known as the world's botanical garden. Calotropis gigantea, a member of the Asclepiadaceae/Apocynaceae family, is also referred to as the Crown Flower and has unique therapeutic properties that can be used alone or in conjunction with other medications to treat common disorders. Herbal medicines have a very wide range of medicinal applications. In ayurveda, the entire dried plant is used as a mucus explusor, parasitic worm expeller, and rejuvenator. Leprosy and asthma are treated with its dried root, while vertigo, baldness, hair loss, and rheumatoid arthritis are all treated with its latex. Calotropis is employed for a variety of conventional and homoeopathic treatments. The plant's many parts can be separated and used as medicine to get a variety of benefits

Binding of Gemini Bisbenzimidazole Drugs with Human Telomeric G-Quadruplex Dimers: Effect of the Spacer in the Design of Potent Telomerase Inhibitors

The study of anticancer agents that act via stabilization of telomeric G-quadruplex DNA (G4DNA) is important because such agents often inhibit telomerase activity. Several types of G4DNA binding ligands are known. In these studies, the target structures often involve a single G4 DNA unit formed by short DNA telomeric sequences. However, the 3′-terminal single-stranded human telomeric DNA can form higher-order structures by clustering consecutive quadruplex units (dimers or n-mers). Herein, we present new synthetic gemini (twin) bisbenzimidazole ligands, in which the oligo-oxyethylene spacers join the two bisbenzimidazole units for the recognition of both monomeric and dimeric G4DNA, derived from d(T2AG3)4 and d(T2AG3)8 human telomeric DNA, respectively. The spacer between the two bisbenzimidazoles in the geminis plays a critical role in the G4DNA stability. We report here (i) synthesis of new effective gemini anticancer agents that are selectively more toxic towards the cancer cells than the corresponding normal cells; (ii) formation and characterization of G4DNA dimers in solution as well as computational construction of the dimeric G4DNA structures. The gemini ligands direct the folding of the single-stranded DNA into an unusually stable parallel-stranded G4DNA when it was formed in presence of the ligands in KCl solution and the gemini ligands show spacer length dependent potent telomerase inhibition properties

A Care Process Model to Deliver 177Lu-Dotatate Peptide Receptor Radionuclide Therapy for Patients With Neuroendocrine Tumors

Purpose: To develop a care process model for the delivery of peptide receptor radionuclide therapy (PRRT) with lutetium-177 (177Lu)-Dotatate for the treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).Methods: A multidisciplinary, structured PRRT process model was established. Over the last 9 months, meetings were held bi-weekly to discuss the logistics of clinical trials. Meetings are still held regularly at the Mayo Clinic Florida to discuss plans regarding commercially available PRRT treatments. The process model has evolved as we have treated patients on both clinical trials and commercial treatments.Results: An effective process model was formulated. We had 5 patients on our Expanded Access Program (EAP) clinical trial. Our ability to be a part of the EAP allowed us to understand the mechanics of how to treat these patients, and what was involved before it became commercially available. Since commercial availability of the 177Lu-Dotatate, more than 50 treatments (>20 patients) have already been completed, with several new patients getting started on treatment every week. Our nuclear medicine department receives continual requests to schedule new patients for PRRT. This can be attributed to our streamlined approach in delivering PRRT to our patients.Conclusion: A thorough procedural approach was formulated to provide patients with PRRT. Experiences and challenges led to refinement, which has allowed the process to advance. This development could lead to better patient outcomes, treatment efficiency, and a reference standard for other institutions trying to develop this at their location

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories. The high quality of the papers and the discussion represent the thinking and experience of experts in their particular fields. The contributed papers also relate to the methodology used in libraries in Asia to provide access to manuscripts and cultural heritage.
