Advancements in nanotechnology-driven photodynamic and photothermal therapies: mechanistic insights and synergistic approaches for cancer treatment.

Cancer is a disease that involves uncontrolled cell division triggered by genetic damage to the genes that control cell growth and division. Cancer starts as a localized illness, but subsequently spreads to other areas in the human body (metastasis), making it incurable. Cancer is the second most prevalent cause of mortality worldwide.

Enhanced photocatalytic degradation of Reactive Red 120 dye under solar light using BiPO@g-CN nanocomposite photocatalyst.

Azo dyes such as Reactive Red 120 raise great concerns about their increased harmfulness. Photocatalytic degradation is considered to be one of the most efficient techniques for Reactive Red 120 degradation. Herein, a highly solar active graphitic carbon nitride-assisted bismuth phosphate nanocomposite (BiPO@g-CN) was synthesized by the thermal decomposition of melamine followed by the co-precipitation method.

Catalytic C-H Bond Activation and Knoevenagel Condensation Using Pyridine-2,3-Dicarboxylate-Based Metal-Organic Frameworks.

Three 1D coordination polymers (CPs) [M(pdca)(HO)] (M = Zn, Cd, and Co; ), and a 3D coordination framework {[(CH)NH][CuK(2,3-pdca)(pa)(NO)]} () (2,3-pdca = pyridine-2,3-dicarboxylate and pa = picolinic acid), have been synthesized adopting a solvothermal reaction strategy. The CPs have been thoroughly characterized using various spectral techniques, that is, elemental analyses, FT-IR, TGA, DSC, UV/vis, and luminescence. Structural information on was obtained by PXRD and X-ray single-crystal analyses, whereas morphological insights were attained through FESEM, AFM, EDX, HRTEM, and BET surface area analyses.

Disseminated cryptococcosis and hepatitis C virus infection: A fatal co-infection.

Background And Purpose: We report a case of disseminated cryptococcosis in a treatment-naïve patient, incidentally diagnosed with hepatitis C virus (HCV) infection and renal parenchymal disease. The patient succumbed to death given the very late diagnosis of the disease.

Case Report: A 54-year-old male presented with the chief complaints of abdominal pain, chest pain, and phlegmy cough for a month.

A systematic review on high conservation value assessment (HCVs): Challenges and framework for future research on conservation strategy.

Various scholars and research institutions have attempted to assess High Conservation Values (HCVs) using different methodologies and approaches. Various countries have developed toolkits to determine High Conservation Value Areas (HCVAs) according to their needs and conservation strategies but there is no global agreement on them. The present study attempts to review research papers and assessment reports from 1999 until 2018 on approaches and methodologies used for HCVs all over the world and provide a review into HCV research systematically, with due consideration to the linkages between Biodiversity, Ecosystem Services and Socio-Economic-Cultural values.

Comparative study of evaluation of the oral stereognostic ability between diabetic and nondiabetic complete denture wearers with and without denture.

Background: The diabetic subjects would have impaired oral stereognostic ability (OSA) compared with normal subjects due to diabetic neuropathy and microcirculatory disturbances. This study was conducted to compare the OSA between diabetic and nondiabetic complete denture wearers with and without denture.

Materials And Methods: In this study the present comparative study comprised of seventy edentulous subjects (36 males and 34 females), aged from 35 to 84 rehabilitated with complete dentures (among them 35 were diabetic and 35 subjects were nondiabetic complete denture wearer).

Multitemporal analysis of forest fragmentation in Hindu Kush Himalaya-a case study from Khangchendzonga Biosphere Reserve, Sikkim, India.

Forests in the mountains are a treasure trove; harbour a large biodiversity; and provide fodder, firewood, timber and non-timber forest products; all of these are essential for human survival in the highest mountains on earth. The present paper attempts a spatiotemporal assessment of forest fragmentation and changes in land use land cover (LULC) pattern using multitemporal satellite data over a time span of around a decade (2000-2009), within the third highest protected area (PA) in the world. The fragmentation analysis using Landscape Fragmentation Tool (LFT) depicts a decrease in large core, edge and patches areas by 5.

An in-vivo correlation analysis of the distance between lingual frenal attachment and mandibular incisal edge position as an aid in establishing mandibular occlusal plane in South Indian population.

Statement Of Problem: The aim of the study is to find the reliability in measuring the distance between the anterior attachment of the lingual frenum and the incisal edge of the mandibular central incisor on casts to be used as a pre-extraction record.

Purpose: The objective of this study is to give a range of numerical values from anterior attachment of lingual frenum to mandibular central incisors in a class I ridge relation in south Indian population, which may be used in establishing the vertical dimension of the edentulous patient and also to locate the mandibular incisors in teeth arrangement of complete denture fabrication.

Materials And Methods: One hundred subjects (50 males and 50 females) under the age group of 21-28y, with class I dental relationship and who have never undergone orthodontic treatment were selected.

Evaluation of the efficacy of probiotics in plaque reduction and gingival health maintenance among school children - A Randomized Control Trial.

Inhibitory effect of GA on the development of thidiazuron-induced somatic embryogenesis in geranium (Pelargonium xhortorum Bailey) hypocotyl cultures.

Somatic embryogenesis in geranium (Pelargonium xhortorum Bailey cv 'Scarlet Orbit Improved') can be achieved by incubating hypocotyl explants on MS medium supplemented with thidiazuron (TDZ; 10 μM for 3 days followed by subculture on medium devoid of any plant growth regulators. The presence of gibberellins (GAs) during both the induction and expression phases of embryogenesis was significantly detrimental to somatic embryo formation on the hypocotyl explants. The addition of the GA-synthesis inhibitors paclobutrazol, uniconazole or ancymidol during the period of growth and differentiation of somatic embryos increased the number of somatic embryos formed on each explant.
