Fluorescence Probes For Bioimaging: Synthesis, Photophysical Properties And Applications, Mehrun Nahar Uddin Dec 2021

Fluorescence Probes For Bioimaging: Synthesis, Photophysical Properties And Applications, Mehrun Nahar Uddin

Dissertations

Fluorescent probes are a vital tool in the study of cell imaging. There are many types of fluorescent probes ranging from inorganic and organic nanoparticles to organic molecules. When used judiciously, they can help provide essential information on cellular structure and function. The introduction of two-photon microscopy has expanded the need for new probes, in particular near-infrared (NIR) absorbing and emitting fluorescent probes. The photochemical and photophysical properties of NIR probes play a crucial role in their effectiveness in cell imaging by both conventional and two-photon excitation (2PE) microscopy. In this research, the synthesis, photophysical properties, and two-photon absorption (2PA) …

Bodipy Based Photodynamic Therapy And Potassium Probes, Xiangshan Liu

Dissertations

Boron dipyrromethene (BODIPY) has become more and more popular in photophysical and biological applications. BODIPY based fluorescence compounds have numerous advantage properties including low toxicity, high absorption extinction coefficients, high fluorescence quantum yields, sharp fluorescence emissions, and resistance to photobleaching. All the good properties lead to the wide applications of BODIPY based compounds. In this research, two different kinds of BODIPY are synthesized. Firstly, BDBrC containing carbazole and BODIPY core is synthesized. Cellular uptake research shows BDBrC can target on lysosome and singlet oxygen generation research result indicates that BDBrC can be used in photodynamic therapy. BDBrC also shows pH-sensitive …


Forecasting Locational Marginal Prices In Electricity Markets By Using Artificial Neural Networks, Kim Jay R. Rosano, Allan C. Nerves Dec 2021

Forecasting Locational Marginal Prices In Electricity Markets By Using Artificial Neural Networks, Kim Jay R. Rosano, Allan C. Nerves

Journal of Economics, Management and Agricultural Development

Electricity price forecasting is an important tool used by market players in decision-making and strategizing their participation in the electricity market. In most studies, market-clearing price is forecasted as it gives an aggregated overview of system price. However, locational marginal price (LMP) gives better outlook of the price particular to the customer location in the electrical power grid. This study utilizes Artificial Neural Networks to forecast weekday LMP of generator and load nodes. Various inputs such as historical prices and demand, and temporal indices were used. Using data for selected nodes of the Philippine Wholesale Electricity Spot Market, forecast Mean …

Reevaluation Of The Described Subspecies Of Euphydryas Phaeton (Drury, 1773) With A Replacement Name For Melitaea Phaeton Schausi (Clark, 1927), Harry Pavulaan Dec 2021

Reevaluation Of The Described Subspecies Of Euphydryas Phaeton (Drury, 1773) With A Replacement Name For Melitaea Phaeton Schausi (Clark, 1927), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The present paper reevaluates the subspecific standing of the nominotypical and three described subspecies of Euphydryas phaeton (Drury, 1773). The nominotypical subspecies phaeton occupies the mid-Atlantic region, with undefined zones of contact with described subspecies borealis (F. Chermock & R. Chermock, 1940) to the north, and subspecies schausi (Clark, 1927) to the south. Nominotypical phaeton is an intermediate phenotype between borealis and schausi, which are each noticeably different from each other but both reasonably similar to intermediate (nominotypical) phaeton. Both borealis and schausi were synonymized under nominotypical phaeton since about time of their descriptions, by authors and list …

Micromentignatha Geberti, A New Tiger Beetle Species From Australia (Coleoptera: Cicindelidae), Jürgen Wiesner

Insecta Mundi

Micromentignatha geberti (Coleoptera: Cicindelidae), new species, is described. It is distinguished from the other members of the genus by its larger body size and shape of elytral maculation.

Due to the kindness of Christian Kerkering, I was able to study specimens of a tiger beetle species he recently acquired. It proved to be new to science and is described herein. It is a member of Micromentignatha Sumlin, 1981, which raises the number of species in this genus to four (Wiesner 2020: 327). A key to distinguish these congeners as well as a catalog of the genus are given herein.

Ardella Magnaemirabilis (Coleoptera: Scarabaeidae: Melolonthinae: Ardellini), A New Scarabaeoid Species, Genus And Tribe From The Southwestern United States, M. J. Paulsen

Insecta Mundi

An interesting new taxon of scarabaeoid beetle is described from western Texas, USA. The remark­ably small chafer, Ardella magnaemirabilis new genus, new species (Coleoptera: Scarabaeidae: Melolonthinae: Ardellini) is described and compared to other diminutive scarabaeoid genera from drier habitats of the southwestern USA. The tribe Ardellini, new tribe, is erected to accommodate the unusual genus.

After a few centuries with entomologists scouring the continent, the discovery of unknown Nearctic scarab gen­era is no longer commonplace. The western United States, in particular, is biogeographically diverse with pockets of endemism that makes such discoveries still possible, driving collectors to continue sampling …

Castellanos, Rudy Chang, Jiahong Sun, Nataraj Jagadeesan, Karen D. Parfitt, David H. Cribbs, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Background

Tumor necrosis factor-α (TNF-α) plays a central role in Alzheimer’s disease (AD) pathology, making biologic TNF-α inhibitors (TNFIs), including etanercept, viable therapeutics for AD. The protective effects of biologic TNFIs on AD hallmark pathology (Aβ deposition and tau pathology) have been demonstrated. However, the effects of biologic TNFIs on Aβ-independent tau pathology have not been reported. Existing biologic TNFIs do not cross the blood–brain barrier (BBB), therefore we engineered a BBB-penetrating biologic TNFI by fusing the extracellular domain of the type-II human TNF-α receptor (TNFR) to a transferrin receptor antibody (TfRMAb) that ferries the TNFR into the brain via …

The Benefits Of Astaxanthin To Improve Pain Relief In Patients With Painful Diabetic Neuropathy: An Open-Label, Randomized Controlled Trial, Rizaldy Taslim Pinzon, Mary Rose Angelina Budi Harsana

Pharmaceutical Sciences and Research

Treatment of diabetic neuropathy is still carried out by providing symptomatic therapy, which only improves ± 50% of the total symptoms felt by patients, but does not tackle the underlying causes of the disease. Astaxanthin is a potent antioxidant, anti-inflammatory, and anti-diabetic carotenoid that could be an additional treatment option. We aimed to measure the effectiveness of administering astaxanthin as an additional therapy to improve the impact of pain and discomfort experienced daily by diabetes mellitus patients with painful diabetic neuropathy. We conducted a randomized experimental study with an open label design of 36 patients who had been diagnosed with …

Physico-Chemical Properties Of Mechanically Extracted Banana Juice At Different Ripening Stages, Mathayo G Mathias, Lilian D Kaale, Oscar Kibazohi

Tanzania Journal of Science

This paper presents the findings of a study on physico-chemical properties of low viscosity banana juice from five banana cultivars: Pisang Awak (PSA) an ABB genome, Yangambi km5 (YKM5) an AAA genome and cultivars from AAA-EA genome, namely Mbilabile, Ndeshi and Mlonga. Low viscosity banana juice was extracted using improved mechanical method at five ripening stages. The physico-chemical properties significantly varied according to cultivars and ripening stages (p < 0.05). Yields, total soluble solids (TSS), titratable acidity (TA) and pH were in the range of 19.50–74.03%, 7.33–27.64 ºBrix, 0.37–0.76% malic acid equivalent and 4.09–4.70, respectively. Yields decreased in the order of Mbilabile > Ndeshi > Mlonga > YKM5 > PSA whereas the total soluble solids increased as follows Mlonga < Mbilabile < Ndeshi < YKM5 < PSA. Furthermore, ashes and mineral contents decreased with ripening stages whereas the low viscosity banana juice was rich in potassium and magnesium. Finally, the study recommends stage 5 of the ripeness as ideal for producing low viscosity banana juice. Keywords: Mechanical extraction, Banana cultivar, Ripening stage, Tannin, Banana juice.
