HPV16 induces penile intraepithelial neoplasia and squamous cell carcinoma in transgenic mice: first mouse model for HPV-related penile cancer.

J Pathol 2020 Jun 3. Epub 2020 Jun 3.

CITAB, Universidade de Trás-os-Montes e Alto Douro, UTAD, Vila Real, Portugal.

Penile cancer is an under-studied disease that occurs more commonly in developing countries and 30-50% of cases show high-risk human papillomavirus (HPV) infection. Therapeutic advances are slow, largely due to the absence of animal models for translational research. Here, we report the first mouse model for HPV-related penile cancer. Read More

Early interconnectivity between metabolic and defense events against oxidative stress induced by cadmium in roots of four citrus rootstocks.

Funct Plant Biol 2016 Oct;43(10):973-985

Cátedra de Fisiología Vegetal, Facultad de Ciencias Naturales e IML, Miguel Lillo 205, CP 4000, Tucumán, Argentina.

The effect of cadmium on roots of four citrus rootstocks was studied to assess the relationships between oxidative stress, carbohydrates, phenolics and antioxidant responses. Swingle citrumelo (SC), Rangpur lime (RL), Troyer citrange (TC) and Volkamer lemon (VL) genotypes were exposed to 0, 5 and 10µM Cd over 7 days, after which Cd accumulation was markedly higher in roots compared with stems and leaves. Malondialdehyde (MDA) and lipoxygenase (LOX) activity increased in Cd-treated SC and RL roots, suggesting that a lipid peroxidation is the main driver of plasma membrane damage. Read More

Serviço de Reumatologia e Doenças Ósseas Metabólicas, Hospital de Santa Maria, CHULN, Centro Académico de Medicina de Lisboa, Lisbon, Portugal.

Giant cell arteritis (GCA) is a granulomatous vasculitis involving large- and middle-sized arteries, with a predilection for cranial arteries. In this paper, we aim to describe a case of a biopsy- and ultrasound-proven GCA, presenting with anterior ischemic optic neuropathy (AION) and normal CRP and ESR at diagnosis and during follow-up, and to review the literature on GCA cases with low inflammatory markers, with a particular focus on the presence of eye involvement. Both CRP and ESR are important in the diagnosis of GCA; occurrence of this disease with normal acute phase reactants is unusual but does not rule out the diagnosis. Read More

Early Reactive A1 Astrocytes Induction by the Neurotoxin 3-Nitropropionic Acid in Rat Brain.

Int J Mol Sci 2020 May 20;21(10). Epub 2020 May 20.

Instituto de Biomarcadores de Patologias Moleculares, Universidad de Extremadura, 06006 Badajoz, Spain.

3-Nitropropionic acid (NPA) administration to rodents produces degeneration of the striatum, accompanied by neurological disturbances that mimic Huntington's disease (HD) motor neurological dysfunctions. It has been shown that inflammation mediates NPA-induced brain degeneration, and activated microglia secreting cytokines interleukin-1α (IL-1α) and tumor necrosis factor α (TNFα) can induce a specific type of reactive neurotoxic astrocytes, named A1, which have been detected in post-mortem brain samples of Huntington's, Alzheimer's, and Parkinson's diseases.

High-sensitivity cardiac troponin I and T methods for the early detection of myocardial injury in patients on chemotherapy.

Clin Chem Lab Med 2020 May 22. Epub 2020 May 22.

Dipartimento di Medicina di Laboratorio, Azienda Ospedaliera Universitaria di Padova, and Dipartimento di Medicina - Università di Padova, Padova, Italy.

Important advances achieved in pharmacological cancer treatment have led progressively to a reduction in mortality from many forms of cancer, and increasing numbers of previously incurable patients can now hope to become cancer-free. Yet, to achieve these improved outcomes a high price has been paid in terms of untoward side effects associated with treatment, cardio-toxicity in particular. Several recent studies have reported that cardiac troponin assay using high-sensitivity methods (hs-cTn) can enable the early detection of myocardial injury related to chemotherapy or abuse of drugs that are potentially cardiotoxic.

Ultrasound Imaging Guide for Assessment of the Intrinsic Ligaments Stabilizing the Subtalar and Midtarsal Joints.

Semin Musculoskelet Radiol 2020 Apr 21;24(2):113-124. Epub 2020 May 21.

Department of Health Sciences (DISSAL), Università di Genova, Genova, Italy.

Ligament injuries around the subtalar, talocalcaneonavicular, and calcaneocuboid joints are often underestimated on clinical and imaging findings during investigation of patients with ankle and foot injuries. Because a delayed diagnosis of midtarsal ligament tears may lead to chronic pain and functional disability, an in-depth knowledge of the complex regional anatomy and of the appropriate ultrasound scanning technique is a prerequisite for evaluating these structures and avoiding misdiagnoses. The objective of this article is twofold: to describe the relevant anatomy and biomechanics related to the ligaments that stabilize the subtalar, talocalcaneonavicular, and calcaneocuboid joints, and to illustrate reasoned landmark-based scanning techniques to provide a systematic examination of these ligaments and thus make ultrasound an effective tool for assessment of patients with suspected subtalar or midtarsal sprain.

High-Resolution Ultrasound of Small Clinically Relevant Nerves Running Across the Posterior Triangle of the Neck.

Semin Musculoskelet Radiol 2020 Apr 21;24(2):101-112. Epub 2020 May 21.

Department of Health Sciences (DISSAL), Università di Genova, Genova, Italy.

With the advent of high-frequency ultrasound (US) transducers, new perspectives have been opened in evaluating millimetric and submillimetric nerves that, despite their dimensions, can be considered relevant in clinical practice. In the posterior triangle of the neck, the suprascapular, long thoracic, phrenic, supraclavicular, great auricular, lesser occipital, and transverse cervical nerves are amenable to US examination and the object of special interest because they may be involved in many pathologic processes or have a value as targets of advanced therapeutic procedures. The correct identification of these nerves requires a deep knowledge of local neck anatomy and the use of a complex landmarks-based approach with US. Read More

[Grey zones in cardiovascular adaptations to physical exercise: how to navigate in the echocardiographic evaluation of the athlete's heart].

G Ital Cardiol (Rome) 2020 Jun;21(6):457-468

Dipartimento CardioToracoVascolare "De Gasperis", ASST Grande Ospedale Metropolitano Niguarda, Milano.

"Athlete's heart" represents a series of mechanisms through which cardiac chambers can adapt to physical activity. Echocardiography has a major role in sports cardiology and it can help physicians to investigate the so-called "grey zones", defined as diagnostic overlaps between athlete's heart and several cardiac diseases: wall thickness and left ventricular size in hypertrophic and dilated cardiomyopathy, ventricular trabeculations in left ventricular non-compaction cardiomyopathy, left atrial size and atrial fibrillation, right ventricular systolic dysfunction in arrhythmogenic right ventricular cardiomyopathy. The use of advanced ultrasound methods such as tissue Doppler and two-dimensional strain can be added to the classic echocardiographic assessment to complete a multi-parametric evaluation, guiding the sports physician and cardiologist in the correct framing of these patients.

Inheritance of Refractive Error in Millennials.

Sci Rep 2020 May 18;10(1):8173. Epub 2020 May 18.

Laboratorio de Óptica, Instituto Universitario de Investigación en Óptica y Nanofísica, Universidad de Murcia, Campus de Espinardo (Ed. 34), 30100, Murcia, Spain.

Over the last decades, the prevalence of myopia has suddenly increased, and at this rate, half of the world's population will be myopic by the year 2050. Contemporary behavioural and lifestyle circumstances, along with emergent technology, are thought to be responsible for this increase. Twin studies mostly reported a high heritability of refractive error across ethnicities. Read More

A Diet Rich in Saturated Fat and Cholesterol Aggravates the Effect of Bacterial Lipopolysaccharide on Alveolar Bone Loss in a Rabbit Model of Periodontal Disease.

Nutrients 2020 May 14;12(5). Epub 2020 May 14.

Institute of Nutrition and Food Technology "José Mataix Verdú", Department of Physiology, Biomedical Research Center, University of Granada, Avda del Conocimiento sn, Armilla, 18016 Granada, Spain.

Increasing evidence connects periodontitis with a variety of systemic diseases, including metabolic syndrome, atherosclerosis, and non-alcoholic fatty liver disease (NAFLD). The proposal of this study was to evaluate the role of diets rich in saturated fat and cholesterol in some aspects of periodontal diseases in a lipopolysaccharide (LPS)-induced model of periodontal disease in rabbits and to assess the influence of a periodontal intervention on hyperlipidemia, atherosclerosis, and NAFLD progression to non-alcoholic steatohepatitis. Male rabbits were maintained on a commercial standard diet or a diet rich in saturated fat (3% lard /) and cholesterol (1. Read More

Update of the recommendations for the determination of biomarkers in colorectal carcinoma: National Consensus of the Spanish Society of Medical Oncology and the Spanish Society of Pathology.

Clin Transl Oncol 2020 May 16. Epub 2020 May 16.

Department of Pathology, University of Valencia, Hospital Clínico Universitario de Valencia, CIBERONC, Valencia, Spain.

In this update of the consensus of the Spanish Society of Medical Oncology (Sociedad Española de Oncología Médica-SEOM) and the Spanish Society of Pathology (Sociedad Española de Anatomía Patológica-SEAP), advances in the analysis of biomarkers in advanced colorectal cancer (CRC) as well as susceptibility markers of hereditary CRC and molecular biomarkers of localized CRC are reviewed. Recently published information on the essential determination of KRAS, NRAS and BRAF mutations and the convenience of determining the amplification of human epidermal growth factor receptor 2 (HER2), the expression of proteins in the DNA repair pathway and the study of NTRK fusions are also evaluated. From the pathological point of view, the importance of analysing the tumour budding and poorly differentiated clusters, and its prognostic value in CRC is reviewed, as well as the impact of molecular lymph node analysis on lymph node staging in CRC.

Organ Culture and Grafting of Choroid Plexus into the Ventricular CSF of Normal and Hydrocephalic HTx Rats.

J Neuropathol Exp Neurol 2020 Jun;79(6):626-640

Instituto de Anatomía, Histología y Patología.

Choroid plexus (CP) may aid brain development and repair by secreting growth factors and neurotrophins for CSF streaming to ventricular and subventricular zones. Disrupted ventricular/subventricular zone progenitors and stem cells lead to CNS maldevelopment. Exploring models, we organ cultured the CP and transplanted fresh CP into a lateral ventricle of postnatal hydrocephalic (hyHTx) and nonhydrocephalic (nHTx) rats. Read More
