Dysfunctional mitochondrial bioenergetics sustains drug resistance in cancer cells.

Resistance to drugs is one of the major issues affecting the response to pharmacological treatments for tumors. Different mechanisms have been proposed to explain the development of cancer drug resistance (CDR), and several approaches to overcome it have been suggested. However, the biological basis of CDR remains unclear.

Physiological Assessment of ECCOR on the Work of Breathing in Exacerbations of COPD.

Rationale: The impact of extracorporeal carbon dioxide removal (ECCOR) on work of breathing and aeration in exacerbations of chronic obstructive pulmonary disease (AECOPD) is poorly understood.

Objectives: The study explores the impact of non-invasive ventilation (NIV) and ECCOR on respiratory drive, effort and distribution of ventilation in AECOPD.

Methods: Patients enrolled in a randomised controlled study of the addition of ECCOR to NIV compared with NIV underwent oesophageal pressure measurement, electrical impedance tomography and parasternal electromyography.

Acquired Hemophilia A After SARS-CoV-2 Infection: A Case Report.

Acquired hemophilia A is a rare autoimmune coagulation disorder associated to the development of neutralizing antibodies directed towards coagulation factor VIII, known as factor VIII inhibitors, in subjects with previous normal clotting system homeostasis and personal and family history negative for bleeding episodes. This condition, although variable in severity and clinical presentation, may lead to severe and life-threatening hemorrhages which can be either spontaneous or associated with traumatic events and invasive procedures. Here we report the case of a 53-year-old woman who was admitted to our Internal Medicine Unit "Cesare Frugoni", Policlinico di Bari, in July 2021, and diagnosed with acquired hemophilia A.

Signal Transduction of Mineralocorticoid and Angiotensin II Receptors in the Central Control of Sodium Appetite: A Narrative Review.

Sodium appetite is an innate behavior occurring in response to sodium depletion that induces homeostatic responses such as the secretion of the mineralocorticoid hormone aldosterone from the zona glomerulosa of the adrenal cortex and the stimulation of the peptide hormone angiotensin II (ANG II). The synergistic action of these hormones signals to the brain the sodium appetite that represents the increased palatability for salt intake. This narrative review summarizes the main data dealing with the role of mineralocorticoid and ANG II receptors in the central control of sodium appetite.

and Oral Carcinogenesis. A Brief Review.

Current medical knowledge and research on patients' management are still evolving, and several protocols on minimizing risk of infection by spp. among the population have developed. The aim of this work is to review the epidemiological and biomolecular characteristics and the various histopathological carcinogenesis hypothesis mechanisms that can occur during infections.

Thyroid disorders in chronic heart failure: from prognostic set-up to therapeutic management.

Thyroid hormones have relevant activity at cardiac and vascular level, by influencing heart rate, myocardial excitability as well as inotropic and lusitropic status, systemic vascular resistance and blood pressure. Moreover, they interact with neuro-hormonal systems such as sympathetic nervous system and renin-angiotensin-aldosterone system thus also indirectly influencing cardiovascular function. Due to these effects, both hypothyroidism and hyperthyroidism, either in their overt or subclinical forms, can have an unfavourable impact in the setting of cardiovascular diseases.
