The intensive use of metal-based nanoparticles results in their continuous release into the environment, leading to potential risks for human health and microbial ecosystems. Although previous studies have indicated that nanoparticles may be toxic to microorganisms, there is a scarcity of data available to assess the underlying molecular mechanisms of inhibitory and biocidal effects of nanoparticles on microorganisms. This study used physiological experiments, microscopy, Live/Dead staining and the genome-wide RNA sequencing to investigate the multiple responses of Pseudomonas aeruginosa to the exposure of copper oxide nanoparticles (CuO NPs)...

INTRODUCTION: Low dose CT screening for lung cancer has a high false positive rate with frequent discovery of indeterminate pulmonary nodules. Noninvasive biomarkers are needed to reduce false positives and improve risk stratification. A retrospective longitudinal evaluation was performed to assess chromosomal aneusomy in sputum via fluorescence in situ hybridization (CA-FISH) in four nested case-control studies. METHODS: ROC analysis resulted in two grouped cohorts: High Risk (CO High Risk and CO Nodule; 68 Cases, 69 controls) and Screening (ACRIN/NLST and PLuSS; 97 Cases, 185 controls)...

The combination of a thorough physical exam and imaging with either MRI or pelvic ultrasound are important in pre-operative planning for deep infiltrating endometriosis. Nevertheless, the 2-dimensional rendering of the pathology by imaging does not always accurately represent intra-operative findings. An in-depth topographical relationship and extent of surrounding tissue invasion can be better appreciated from 3-dimensional modeling. A 49 year old patient with history of endometriosis and persistent pain underwent pre-operative imaging with MRI that was consistent with infiltrating endometriosis...

A healthy 31-year-old woman presented with a 20-year history of asymptomatic skin-colored papules and nodules on the central area of the face. Her maternal grandmother, aunts, mother, and sister also had similar lesions. Clinical, histopathological, and genetic features allowed the diagnosis of multiple familial trichoepithelioma. The patient and family were referred to the genetic department for genetic counselling. Close follow-up for the possibility of secondary basal cell carcinoma is warranted.

Gouty panniculitis is caused by the deposition of urate crystals in the subcutaneous tissue, accompanied by a lobular panniculitis. It presents as subcutaneous nodules, most commonly located on the lower extremities. Being an unusual clinical presentation of gout, the sonographic findings of gouty panniculitis have been scarcely described in the literature. Our report describes the ultrasound features we found in a case of gouty panniculitis and the usefulness of this technique for diagnosis and monitoring of this disease...

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a distinctive lymphocyte rich vasoformative proliferation comprising epithelioid-appearing endothelial cells with partially canalized capillary vessels in a lymphohistiocytic and eosinophil rich environment. ALHE presents clinically as single or multiple pink-brown dome-shaped papules or nodules, most commonly on the ear and peri-auricular area, followed by the face, and scalp. ALHE involving the subungual unit is rare with only 5 previously reported cases and all involved the underlying bone...

Soft tissue amyloidoma is a rare condition that presents primarily in the abdomen and/or mediastinum and more uncommonly on the extremities(1) . Soft tissue amyloidomas on the extremities have been associated with chronic inflammation, particularly when accompanied by AA-type amyloid deposition as seen in local trauma, surgery, hypertension, and diabetes(2) . To our knowledge, this is the first reported case of nodular cutaneous amyloidoma in the setting of systemic and cutaneous sarcoidosis. A 65-year-old woman presented with an asymptomatic subcutaneous nodule above her left lateral malleolus...

BACKGROUND: Thyroid nodules are usually benign; however, 5 to 15% prove to be malignant. Fine-needle aspiration (FNA) has become the gold standard in the evaluation of thyroid nodules, especially in single nodule more than a centimeter and / or in smaller nodule with ultrasound characters of malignancy. METHODS: We evaluated retrospectively 179 patients with "undetermined" thyroid fine needle aspiration, undergoing surgery. We compared cytology and histology and we evaluated sex, age, the presence of thyroiditis and dimension of the indeterminate nodule as predictors of malignancy...
