When the Stomach Takes a Vacation: The Unseen Battles of Gastroparesis

Gastroparesis is a syndrome characterised by delayed gastric emptying that is usually idiopathic, diabetic, or iatrogenic. This underdiagnosed disease has a substantial influence on the quality of life of its patients. We present the case of an 86-year-old man with dementia, benign prostatic hyperplasia, and gastroesophageal reflux disease who developed symptoms of gastroparesis during a lengthy hospital stay. ...

Under my Skin: the Psychosocial Dimension of Psoriasis

Disruption of ph dynamics suppresses proliferation and potentiates doxorubicin ...

The reverse pH gradient is a major feature associated with cancer cell reprogrammed metabolism. This phenotype is supported by increased activity of pH regulators like ATPases, carbonic anhydrases (CAs), monocarboxylate transporters (MCTs) and sodium–proton exchangers (NHEs) that induce an acidic tumor microenvironment, responsible for the cancer acid-resistant phenotype. In this work, we analyzed the expressio...

Hypoxia and macrophages act in concert towards a beneficial outcome in colon ca...

In colon cancer, the prognostic value of macrophages is controversial, and it is still unknown how hypoxia modulates macrophage–cancer cell crosstalk. To unravel this, co-cultures of human primary macrophages and colon cancer cells were performed at 20% and 1% O2, followed by characterization of both cellular components. Different colon cancer patient cohorts were analyzed for hypoxia and immune markers, and th...

The Mechanisms Underlying the Biological Response to Wear Debris in Periprosthe...

Joint replacement surgery is the gold-standard therapeutic approach to treat patients with end-stage hip and knee arthritis, providing pain relief and joint function recovery. Despite the improvements in implant design and surgical techniques, revisions after total joint replacement are expected to grow. The periprosthetic inflammation, featured by the sustained inflammatory response to the implant debris, elic...

The crosstalk between cell adhesion and cancer metabolism

Cancer cells preferentially use aerobic glycolysis over mitochondria oxidative phosphorylation for energy production, and this metabolic reprogramming is currently recognized as a hallmark of cancer. Oncogenic signaling frequently converges with this metabolic shift, increasing cancer cells’ ability to produce building blocks and energy, as well as to maintain redox homeostasis. Alterations in cell-cell and cel...

SRC inhibition prevents P-cadherin mediated signaling and function in basal-lik...

BACKGROUND: Basal-like breast cancer (BLBC) is a poor prognosis subgroup of triple-negative carcinomas that still lack specific target therapies and accurate biomarkers for treatment selection. P-cadherin is frequently overexpressed in these tumors, promoting cell invasion, stem cell activity and tumorigenesis by the activation of Src-Family kinase (SRC) signaling. Therefore, our aim was to evaluate if the trea...

Hypoxia promotes breast cancer cell invasion through HIF-1a-mediated up-regulat...

Hypoxia is a common feature of solid tumours that promotes invasion and metastatic dissemination. Invadopodia are actin-rich membrane protrusions that direct extracellular matrix proteolysis and facilitate tumour cell invasion. Here, we show that CSRP2, an invadopodial actin bundling protein, is upregulated by hypoxia in various breast cancer cell lines, as well as in pre-clinical and clinical breast tumour spe...

Geometric compensation applied to image analysis of cell populations with morph...

Immunofluorescence is the gold standard technique to determine the level and spatial distribution of fluorescent-tagged molecules. However, quantitative analysis of fluorescence microscopy images faces crucial challenges such as morphologic variability within cells. In this work, we developed an analytical strategy to deal with cell shape and size variability that is based on an elastic geometric alignment algo...

Infeção tardia por streptococcus agalactiae – um caso de artrite séptica neonatal

RESUMO Introdução: A incidência da infeção neonatal precoce por Estreptococo do grupo B (EGB) tem diminuído substancialmente devido ao rastreio da colonização por EGB nas grávidas entre as 35 e as 37 semanas de gestação e à instituição da quimioprofilaxia intraparto. No entanto, a incidência da infeção tardia tem-se mantido constante na última década, não sendo afetada pela quimioprofilaxia materna intraparto. ...
