Prognostic Value of Tumor Budding for Early Breast Cancer.

Background: Tumor budding (TB) is a dynamic process associated with the epithelial-mesenchymal transition and a well-established prognostic biomarker for colorectal cancer. As part of the tumor microenvironment, tumor buds demonstrate increased cell motility and invasiveness. Current evidence demonstrates that high levels of TB correlate with disease progression and worst outcomes across different solid tumors.

Incidental cerebral aneurysm after takotsubo cardiomyopathy: A case report.

Takotsubo syndrome (TS) is an acute heart disease that mimics the typical features of acute coronary syndrome (ACS). TS is generally reported after subarachnoid hemorrhage (SAH) due to a ruptured aneurysm, and has an incidence rate of 0.8 (17%).

Virulence strategies of an insect herbivore and oomycete plant pathogen converge on host E3 SUMO ligase SIZ1.

Pathogens and pests secrete proteins (effectors) to interfere with plant immunity through modification of host target functions and disruption of immune signalling networks. The extent of convergence between pathogen and herbivorous insect virulence strategies is largely unexplored. We found that effectors from the oomycete pathogen, Phytophthora capsici, and the major aphid pest, Myzus persicae target the host immune regulator SIZ1, an E3 SUMO ligase.

Non-Secretory Multiple Myeloma with Patchy Marrow Involvement and Aberrant Cytokeratin Expression.

Non-secretory multiple myeloma is a rare form of the disease that presents a diagnostic challenge. A 69-year-old woman presented to the emergency department with a pathological fracture of the right clavicle, along with a history of asthenia and middle back pain in the preceding three months. Workup revealed multiple focal lytic bone lesions in the clavicles, ribs, skull and thoracic- lumbar-sacral spine, without evidence of anemia, hypercalcemia or renal failure, with no abnormal immunofixation in the serum or urine and with normal serum free light chain ratios.

The pathogenic fungi was identified as and treated with chemical abrasion of the nail with 40% urea and application of terbinafine cream. Onychomycosis caused by species is rare, and this is the second reported case.

Hysteroscopic Findings Related with the Assessment and Treatment of Uterine Florid Cystic Endosalpingiosis: A Case Report and Review of All the Published Cases.

Introduction: Endosalpingiosis is a rare benign condition characterized by the presence of tubal epithelium outside the Fallopian tube. The clinical presentation of endosalpingiosis is nonspecific, and the diagnosis is typically incidental in women undergoing surgery for pelvic pain, infertility, urinary symptoms, or a pelvic mass. It can only be confirmed with histopathological examination.

Untreated sewage contamination of beach sand from a leaking underground sewage system.

Thirty people (mostly children) experienced an episode of skin rash days after a sand sifting beach operation at Porto Pim Beach in Faial, Azores during June 2019. An environmental and epidemiologic investigation was conducted to identify the cause of the outbreak of skin rash. The epidemiologic investigation found that some of the patients experiencing symptoms had never entered the beach water.

Prospects for the Use of Whey for Polyhydroxyalkanoate (PHA) Production.

Plastic production and accumulation have devastating environmental effects, and consequently, the world is in need of environmentally friendly plastic substitutes. In this context, polyhydroxyalkanoates (PHAs) appear to be true alternatives to common plastics because they are biodegradable and biocompatible and can be biologically produced. Despite having comparable characteristics to common plastics, extensive PHA use is still hampered by its high production cost.

Effects of sub-seabed CO leakage: Short- and medium-term responses of benthic macrofaunal assemblages.

The continued rise in atmospheric carbon dioxide (CO) levels is driving climate change and temperature shifts at a global scale. CO Capture and Storage (CCS) technologies have been suggested as a feasible option for reducing CO emissions and mitigating their effects. However, before CCS can be employed at an industrial scale, any environmental risks associated with this activity should be identified and quantified.

Sporotrichosis by senso stricto with itraconazole resistance and terbinafine sensitivity observed and : Case report.

We report a case of a patient with lymphocutaneous sporotrichosis in the right upper limb. The fungus was identified as senso stricto by calmodulin gene sequencing. The initial treatment was itraconazole (200 mg/day), but antifungal susceptibility demonstrated high resistant to this and another six antifungals, with exception to terbinafine.

Infection with Opisthorchis felineus induces intraepithelial neoplasia of the biliary tract in a rodent model.

The liver fluke Opisthorchis felineus is a member of the triad of epidemiologically relevant species of the trematode family Opisthorchiidae, and the causative agent of opisthorchiasis felinea over an extensive range that spans regions of Eurasia. The International Agency for Research on Cancer classifies the infection with the liver flukes Opisthorchis viverrini and Clonorchis sinensis as group 1 agents and a major risk factor for cholangiocarcinoma. However, the carcinogenic potential of the infection with O.

Breast cancer in Angola, molecular subtypes: a first glance.

Purpose: The aim of this study was to investigate the breast cancer (BC) molecular subtypes according to its surrogate immunohistochemistry (IHC) markers. We conducted a preliminary study, to correlate the clinical pathological profiles and molecular subtypes of breast cancer in Luanda, Angola.

Methods: From January 2011 to 30 December 2014, 140 consecutive cases of microscopically confirmed invasive breast carcinoma were classified regarding histology and IHC (ER, PR, HER2, and Ki-67).

Random mutagenesis screen shows that Phytophthora capsici CRN83_152-mediated cell death is not required for its virulence function(s).

With the increasing availability of plant pathogen genomes, secreted proteins that aid infection (effectors) have emerged as key factors that help to govern plant-microbe interactions. The conserved CRN (CRinkling and Necrosis) effector family was first described in oomycetes by their capacity to induce host cell death. Despite recent advances towards the elucidation of CRN virulence functions, the relevance of CRN-induced cell death remains unclear.

A Perspective on CRN Proteins in the Genomics Age: Evolution, Classification, Delivery and Function Revisited.

Plant associated microbes rely on secreted virulence factors (effectors) to modulate host immunity and ensure progressive infection. Amongst the secreted protein repertoires defined and studied in pathogens to date, the CRNs (for CRinkling and Necrosis) have emerged as one of only a few highly conserved protein families, spread across several kingdoms. CRN proteins were first identified in plant pathogenic oomycetes where they were found to be modular factors that are secreted and translocated inside host cells by means of a conserved N-terminal domain.

Targeted O-glycoproteomics explored increased sialylation and identified MUC16 as a poor prognosis biomarker in advanced-stage bladder tumours.

Bladder carcinogenesis and tumour progression is accompanied by profound alterations in protein glycosylation on the cell surface, which may be explored for improving disease management. In a search for prognosis biomarkers and novel therapeutic targets we have screened, using immunohistochemistry, a series of bladder tumours with differing clinicopathology for short-chain O-glycans commonly found in glycoproteins of human solid tumours. These included the Tn and T antigens and their sialylated counterparts sialyl-Tn(STn) and sialyl-T(ST), which are generally associated with poor prognosis.

CO leakage from carbon dioxide capture and storage (CCS) systems affects organic matter cycling in surface marine sediments.

Carbon dioxide capture and storage (CCS), involving the injection of CO into the sub-seabed, is being promoted worldwide as a feasible option for reducing the anthropogenic CO emissions into the atmosphere. However, the effects on the marine ecosystems of potential CO leakages originating from these storage sites have only recently received scientific attention, and little information is available on the possible impacts of the resulting CO-enriched seawater plumes on the surrounding benthic ecosystem. In the present study, we conducted a 20-weeks mesocosm experiment exposing coastal sediments to CO-enriched seawater (at 5000 or 20,000 ppm), to test the effects on the microbial enzymatic activities responsible for the decomposition and turnover of the sedimentary organic matter in surface sediments down to 15 cm depth.

Hypoxia enhances the malignant nature of bladder cancer cells and concomitantly antagonizes protein O-glycosylation extension.

Invasive bladder tumours express the cell-surface Sialyl-Tn (STn) antigen, which stems from a premature stop in protein O-glycosylation. The STn antigen favours invasion, immune escape, and possibly chemotherapy resistance, making it attractive for target therapeutics. However, the events leading to such deregulation in protein glycosylation are mostly unknown.

Aggressive Angiomyxoma in Pregnancy: A Rare Condition, a Common Misdiagnosis.

Introduction. Aggressive angiomyxoma is a rare mesenchymal neoplasm. Although benign in the majority of the cases, these neoplasms usually present a locally infiltrative nature and high rates of recurrence.

SIXTEEN YEARS OF DERMATOMYCOSIS CAUSED BY Candida spp. IN THE METROPOLITAN AREA OF PORTO ALEGRE, SOUTHERN BRAZIL.

The yeasts of the genus Candida infect skin, nails, and mucous membranes of the gastrointestinal and the genitourinary tract.

Metabolic coupling in urothelial bladder cancer compartments and its correlation to tumor aggressiveness.

Monocarboxylate transporters (MCTs) are vital for intracellular pH homeostasis by extruding lactate from highly glycolytic cells. These molecules are key players of the metabolic reprogramming of cancer cells, and evidence indicates a potential contribution in urothelial bladder cancer (UBC) aggressiveness and chemoresistance. However, the specific role of MCTs in the metabolic compartmentalization within bladder tumors, namely their preponderance on the tumor stroma, remains to be elucidated.
