Trajectories and Status of Transgender Elderly Across the World and in Spain: A Narrative Review

Received: 06 November 2023;  Published: 27 February 2024;  doi: 10.21926/obm.geriatr.2401271

Abstract

Older trans people have been largely unaddressed both in the context of the LGBTIQ+ community and in studies on geriatrics and aging. This literature review compiles up-to-date information on transgender elders, providing a summary of the Spanish historical context in which trans people have been raised, and analyzes the areas in which to center possible courses of action and research on a global scale. The themes tackled are the presence of victimization and violence; the effects of medical transition, taking into [...]

Applications of Generative Large Language Models in Environmental Science: A Systematic Review

Received: 07 April 2025;  Published: 12 August 2025;  doi: 10.21926/aeer.2503028

Abstract

Environmental science addresses critical global challenges, including climate change, biodiversity loss, and sustainability. These complex topics generate a vast amount of both structured and unstructured data, from remote sensing output to policy documents, guidelines, and scientific literature. Effectively processing and utilizing this information is essential for advancing research and supporting decision-making. Large Language Models (LLMs) have shown remarkable capabilities in natural language understanding an [...]

Osteoporosis in Postmenopausal Women with Breast Cancer

Received: 07 December 2020;  Published: 05 July 2021;  doi: 10.21926/obm.geriatr.2103173

Abstract

Breast cancer and osteoporosis are both diseases of aging. The "one in eight" lifetime risks of breast cancer occur primarily in the sixth, seventh, eighth, and ninth decades of life. One-third of postmenopausal women will experience an osteoporotic fracture. It is the coalescence of osteoporosis, breast cancer, and breast cancer treatments that, in some cases, increases the risks of osteoporotic fracture. That makes it imperative to assess risk factors, screen, and prevent or treat osteoporosis in postmenopausal w [...]

Pd-Ni-B/C Nanocatalysts for Electrochemical Oxidation of Ethanol in Alkaline Media

Received: 06 September 2022;  Published: 19 January 2023;  doi: 10.21926/cr.2301005

Abstract

This paper describes the synthesis of Pd0.70-Nix-By nanoparticles (x:y = 0.30:0, 0:0.30, 0.25:0.05, 0.20:0.10, 0.15:0.15, and 0.10:0.20) supported on carbon Vulcan XC-72 R by the chemical reduction method using ethylene glycol as a reducing agent for the study of the electrochemical oxidation of ethanol in alkaline media. Neither surfactants nor templates were used during the syntheses. The catalysts were physically characterized by transmission electron microscopy that showed the formation of nanoparticles with di [...]

Cancer Cachexia: The Comparative Mechanisms of Weight Loss after Esophagectomy and Bariatric Surgery

Received: 12 October 2020;  Published: 17 May 2021;  doi: 10.21926/obm.icm.2102017

Abstract

Oesophageal cancer is the ninth most common cancer and the sixth most common cause of cancer deaths worldwide [1]. Over the past number of years, due to earlier diagnosis and better treatment, we are seeing improvements in the survival rates of oesophageal cancer, with more patients living longer post-esophagectomy surgery. Unintentional weight loss is a common unintended feature seen in patients post-esophagectomy done with curative intent. Many recent studies have demonstrated the links between the pathophysiolog [...]

Storable Energy Production from Wind over Water

Received: 28 January 2020;  Published: 29 April 2020;  doi: 10.21926/jept.2002005

Abstract

The current status of a project is described which aims to demonstrate the technical and economic feasibility of converting the vast wind energy available over the globe’s oceans and lakes into storable energy. To this end, autonomous high-performance sailing ships are equipped with hydrokinetic turbines whose output is stored either in electric batteries or is fed into electrolysers to produce hydrogen which then is compressed and stored in tanks. In the present paper, the previous analytical studies which showed [...]

Mesoporous Silica Nanoparticles to Tune Oxidative Degradation Rates in Composite Shape Memory Polymers

Received: 12 September 2019;  Published: 31 December 2019;  doi: 10.21926/rpm.1904008

Abstract

Biomedical applications of shape memory polymers (SMPs) are limited by their biostability, degradability, and possible toxicity risks after implantation. Mesoporous silica nanoparticles (MSNs) were used to increase the oxidative biostability (increase time until degradation occurs) using antioxidants and to induce oxidative degradation through incorporation of hydrogen peroxide-containing MSNs with modified surfaces. The presented results confirm increased oxidative stability using antioxidants, and alternatively, [...]

Febrile Neutropenia in Children: Etiologies, Outcomes, and Risk Factors with Prolonged Fever

Received: 27 November 2019;  Published: 21 February 2020;  doi: 10.21926/obm.transplant.2001102

Abstract

Most studies of children with prolonged fever and neutropenia (PFN) have focused on invasive fungal disease (IFD) as the etiology of fever and not on other causes. Data are lacking regarding risk factors and adverse outcomes in pediatric cancer patients with PFN compared with those whose fevers resolve more rapidly. Retrospective medical record review was performed for all cancer patients with febrile neutropenia (FN) in the pediatric oncology unit at University of Chicago Medicine Comer Children’s Hospital f [...]

In Silico Detection and FISH Analysis to Determine Location of miRNAs in Solea senegalensis Chromosomes Using BACs

Received: 31 July 2018;  Published: 24 October 2018;  doi: 10.21926/obm.genet.1804044

Abstract

Background: MicroRNAs (miRNAs) are small, non-coding RNAs that play a very important role in gene expression by regulating mRNA cleavage and translation. The Senegalese sole, Solea senegalensis (Kaup 1858), is a flatfish species that shows great potential for marine aquaculture. Nevertheless, the existence of sexual dysfunction of males reared in captivity, high larval mortality, and diseases have hampered its production. The integration of sequence information with data on chromosomal physical location is useful f [...]

Redirecting Fetal Programming: Evidence of Interventions that May Be A Tool for Health

Received: 01 June 2018;  Published: 28 December 2018;  doi: 10.21926/obm.genet.1804058

Abstract

Understanding the pathophysiology of disease can be an essential step to determining where and how to intervene for preventive or corrective health. Intrauterine growth restriction (IUGR) has been defined in livestock species as impaired gestational development of a fetus or its parts [1]. This broad category of ailments described by low fetal weight is accompanied by susceptibility to adult onset of chronic disease through fetal programming of numerous organ systems and their functions. This concern affects humans [...]
