RESUMO
Ferrous sulfate is a commonly prescribed drug for prophylaxis and treatment purposes, particularly in women and adolescent girls. However, its easy availability, potential toxicity at higher doses, and vague clinical presentation make it a drug of concern when evaluating a case of poisoning. We present the case of a 28-year-old female who allegedly consumed 60 ferrous sulfate (60 mg of elemental iron in 200 mg of ferrous sulfate) tablets in a suicidal attempt. She presented with gastrointestinal disturbances on the same day to a tertiary care health facility. Investigations revealed deranged liver function tests, serum iron levels ten times the normal range, and high levels of saturated transferrin. Despite treatment, she succumbed to the poisoning 4 days after the incident. Autopsy showed features of liver failure, which was confirmed by histopathology. Chemical examination detected free ferrous and chloride ions. This fatal case of adult iron toxicity highlights the different causes of death in various stages of iron toxicity, providing a wider perspective on clinical management and aiding in the determination of the cause of death during an autopsy. This article adds a rare fatal iron poisoning case in adults to the literature, emphasizing the necessity for regulating iron tablet supplementation and raising public awareness of the toxicity of iron, which could save millions of lives.
RESUMO
BACKGROUND: The adolescent and young adult (AYA) age group is a bridge between pediatric and adult age groups. The present study describes the epidemiology of cancers in the AYA age group in India. METHODS: The data of primary site cancers in the age group of 15-39 years from the 28 Population Based Cancer Registries (PBCRs') and 58 Hospital Based Cancer Registries under the National Cancer Registry Programme for the reporting year 2012-2016 was analysed. RESULTS: The median age adjusted incidence rate (AAR) was 22.2 per 100,000 among males and 29.2 per 100,000 among females. The age-specific incidence rate increased with increasing age in both genders with the highest recorded numbers in the 35-39 age group. The proportion of myeloid leukaemia and non-Hodgkin's lymphoma was highest in the 15-24 age group. Cancers of the breast, thyroid, mouth and tongue constituted the leading sites between 30 and 39 years. There was a significant increase in the incidence among AYA males (APC=0.9) between 1985 and 2015, while a decline in incidence was observed for females, which was not significant (APC=-0.2). The majority of patients had locoregional spread of cancer at the time of diagnosis. The projected number of cancer cases in both genders are expected to increase to 178,617 in 2025. CONCLUSION: Cancers in the AYA population are a concern in India. Since AYA oncology appears to be evolving in India, a robust health care system and suitable AYA cancer care policies and programmes are strongly needed to improve disease outcomes and survival.

Mixed ligand complexes of Ni(II) with 1,10-phenanthroline (1,10-Phen) and Schiff bases L(1)(MIIMP); L(2)(CMIIMP); L(3)(EMIIMP); L(4)(MIIMNP); L(5)(MEMIIMP); L(6)(BMIIMP); L(7)(MMIIMP); L(8)(MIIBD) have been synthesized. These metal chelates have been characterized by elemental analysis, IR, (1)H-NMR, (13)C-NMR, Mass, UV-Vis, magnetic moments, and thermogravimetric (TG&DTA) analysis. Spectral data showed that the 1,10-phenanthroline act as neutral bidentate ligand coordinating to the metal ion through two nitrogen donor atoms and Schiff bases acts as monobasic bidentate coordinating through NO donor atoms. All Ni(II) complexes appear to have an octahedral geometry. The antimicrobial activity of mixed ligand complexes has been studied by screening against various microorganisms, it is observed that the activity enhances upon coordination. The DNA binding studies have been investigated by UV-Vis spectroscopy, and the experimental results indicate that these complexes bind to CT DNA with the intrinsic binding constant K(b) = 2.5 ± 0.2 × 10(5) M(-1). MTT is used to test the anticancer effect of the complexes with HL60 tumor cell. The inhibition ratio was accelerated by increasing the dosage, and it had significant positive correlation with the medication dosage.
RESUMO
OBJECTIVES: The purpose of this study was to investigate the anticancer activity of anticancer drugs (5-fluorouracil and 6-thioguanine) in polymeric nanocapsules in the presence and in the absence of gold and iron oxide nanoparticles toward Hep2 cancer cells. MATERIALS AND METHODS: MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay was used for quantitative measurements for the anticancer cell activity. Encapsulated drug in polyethylene terephthalate-polylactic acid copolymer (PET-co-PLA) nanocapsules in the presence and absence of gold and iron oxide nanoparticles were prepared via the W/O/W emulsification solvent-evaporation method. Morphology of the nanoparticles was characterized by transmission electron microscopy and scanning electron microscopy. CONCLUSION: The average size of the polymeric nanocapsules, gold nanoparticles, and iron oxide nanoparticles were found to be in range of 230-260, 18 -20 nm, 5-10 nm, respectively. The findings in this study inferred that incorporated drug in polymeric nanocapsules with gold nanoparticles and iron oxide nanoparticles show better anticancer activity when compared with encapsulated drug in polymeric nanocapsules.
RESUMO
This work describes a bioassisted approach for the preparation of metal nanoparticles using yeast species Hansenula anomala. Gold nanoparticles were prepared using gold salt as the precursor, amine-terminated polyamidoamine dendrimer as the stabilizer, and the extracellular material from H. anomala as the bioreductant. It could also be demonstrated that, using our approach, small molecules such as cysteine can act as stabilizers as well. This synthetic approach offers a greener alternative route to the preparation of gold sols that are devoid of cellular and toxic chemical components. The ability of as-synthesized gold sol to function as biological ink for producing patterns for the analysis of fingerprints and to act as an antimicrobial reagent is evaluated. The generality of this toxin-free synthetic approach to other metals was assessed using palladium and silver.
