PG & Research Department of Mathematics, Sanatana Dharma College, Kerala University, Alappuzha, Kerala, 688003, India.

Holey nanographene, an allotrope of carbon arranged in two dimensions, has gained remarkable attention as a nanomaterial with several potential uses in numerous industries, such as electronics, energy storage, healthcare, and environmental cleanup, because of its high carrier mobility, flexibility, transparency, high surface area, conductivity, and chemical stability. The fundamental holey nanographene is assembled in a linear form to create the holey nanographene chain (HNC) that is being discussed. To fully utilize it in various applications, it is essential to comprehend the basic ideas guiding its behavior at the nanoscale; for that, we find various topological indices for this holey nanographene chain using the cut method.

As a promising candidate for tackling drug-resistant cancers, triptolide, a diterpenoid derived from the Chinese medicinal plant Tripterygium wilfordii, has been developed. This review summarizes potential antitumor activities, including the suppression of RNA polymerase II, the suppression of heat shock proteins (HSP70 and HSP90), and the blockade of NF-kB signalling. Triptolide is the first known compound to target cancer cells specifically but spare normal cells, and it has success in treating cancers that are difficult to treat, including pancreatic, breast, and lung cancers.

Transcatheter closure (TCC) of certain ventricular septal defect (VSD) subtypes typically requires arteriovenous loop (AVL) formation or retrograde transarterial deployment. Upfront transvenous cannulation from the right ventricle avoids arterial access and loop-related complications. We retrospectively reviewed data of patients who underwent TCC for perimembranous, intraconal, and post-surgical residual VSDs at our institution (January 2019-December 2023).

Electronic coupling between individual redox units in a molecular assembly dictates their charge transfer efficacy. Being a well-defined crystalline structure, the metal-organic framework (MOF) ensures proper positioning of redox-active moieties and provides a unique platform to unveil their charge transfer dynamics and quantification with structural relationships. Here, we demonstrate a novel redox-active MOF with near-infrared through-space intervalence charge transfer by introducing a mixed valence state inside redox-active thiazolothiazole-based ligands (DPTTZ) upon photo- or electrochemical reduction.

Tryptophan catabolism is a central pathway in many cancers, serving to sustain an immunosuppressive microenvironment. The key enzymes involved in this tryptophan metabolism such as indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are reported as promising novel targets in cancer immunotherapy. IDO1 and TDO overexpression in TNBC cells promote resistance to cell death, proliferation, invasion, and metastasis.

Socio-economic inequalities in second primary cancer incidence: A competing risks analysis of women with breast cancer in England between 2000 and 2018.

Int J Cancer

January 2025

Inequalities in Cancer Outcomes Network (ICON) group, Department of Health Services Research and Policy, Faculty of Public Health and Policy, London School of Hygiene & Tropical Medicine, London, UK.

We aimed to investigate socio-economic inequalities in second primary cancer (SPC) incidence among breast cancer survivors. Using Data from cancer registries in England, we included all women diagnosed with a first primary breast cancer (PBC) between 2000 and 2018 and aged between 18 and 99 years and followed them up from 6 months after the PBC diagnosis until a SPC event, death, or right censoring, whichever came first. We used flexible parametric survival models adjusting for age and year of PBC diagnosis, ethnicity, PBC tumour stage, comorbidity, and PBC treatments to model the cause-specific hazards of SPC incidence and death according to income deprivation, and then estimated standardised cumulative incidences of SPC by deprivation, taking death as the competing event.

Background: Obstructive sleep apnea syndrome (OSAS) is a prevalent condition characterised by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to disrupted sleep and associated morbidities. Orthognathic surgery (OGS) has been proposed as a treatment option for OSAS, aimed at anatomically repositioning the maxillofacial structures to alleviate airway obstruction. This systematic review and meta-analysis aimed to evaluate the efficacy of OGS in reducing apnea-hypopnea index (AHI) and Epworth Sleepiness Scale (ESS) scores among OSAS patients.

Mass vaccination against peste des petits ruminants (PPR) in two southern states of India, namely Andhra Pradesh and Karnataka, has reduced disease outbreaks significantly. The sporadic outbreaks reported now can be attributed in part to the recurring movement of sheep and goats between these contiguous states. This study assessed the present level of economic burden and impact of vaccination on the local system (one state), considering the exposure from the external system (neighboring state) using a system dynamic (SD) model.

Microneedle(MN)-based drug delivery is one of the potential approaches to overcome the limitations of oral and hypodermic needle delivery. An in silico model has been developed for hollow microneedle (HMN)-based drug delivery in the skin and its subsequent absorption in the blood and tissue compartments in the presence of interstitial flow. The drug's reversible specific saturable binding to its receptors and the kinetics of reversible absorption across the blood and tissue compartments have been taken into account.
