BACKGROUND: Basal cell carcinomas (BCCs) are uncommon feline skin neoplasms of uncertain cause. CASE: A 14-year-old Abyssinian cat developed a soft dermal nodule on the dorsal thorax. This mass grew slowly over a six month period before being surgically excised. METHODS AND RESULTS: Histology revealed a BCC. Additionally, changes suggestive of an early Bowenoid in situ carcinoma (BISC) were present in the overlying epidermis. Both the BCC and the BISC contained papillomavirus-induced cell changes and prominent basophilic intracytoplasmic bodies...

PURPOSE: Hepatocellular carcinoma (HCC) with a "nodule-in-nodule" (NIN) appearance has unique histological characteristics as an early HCC. We assessed long-term therapeutic outcomes of radiofrequency ablation (RFA) in HCC patients considering this appearance. MATERIALS AND METHODS: Our Institutional Review Board approved this retrospective study, and the requirement for written informed consent was waived. Between May 2006 and April 2012, a total of 572 patients underwent RFA for single HCC as a first-line treatment...

Biomedical coatings for orthopedic implants should facilitate osseointegration and mitigate implant-induced inflammatory reactions. Cerium oxide (CeO2) ceramics possess anti-oxidative properties and can be used to decrease mediators of inflammation, which makes them attractive for biomedical applications. In our work, two kinds of CeO2 incorporated hydroxyapatite coatings (HA-10Ce and HA-30Ce) were prepared via plasma spraying technique and the effects of CeO2 addition on the responses of bone mesenchymal stem cells (BMSCs) and RAW264...

BACKGROUND AND PURPOSE: Although core needle biopsy was introduced as a diagnostic alternative to fine-needle aspiration, the utility and safety of core needle biopsy for thyroid nodules in a large population has yet to be studied comprehensively. We evaluate core needle biopsy yields on a large-scale basis to investigate its potential in the preliminary diagnosis of thyroid nodules. MATERIALS AND METHODS: Between March 2005 and December 2013, 2448 initially detected thyroid nodules from 2120 consecutive patients who underwent core needle biopsy were retrospectively evaluated...

Effective therapeutic options for advanced hepatocellular carcinoma are limited. Hematopoietic stem cell transplantation may offer a graft-versus-tumor effect. Combined liver and hematopoietic stem cell transplantation from the same donor with preparatory conditioning may promote tolerogenicity to the liver allograft and offers the potential for immunosuppression withdrawal. We report our experience with the use of this approach in a pediatric patient with invasive hepatocellular carcinoma and pulmonary metastases who underwent a living-donor liver transplantation followed by reduced-toxicity myeloablative conditioning and hematopoietic stem cell transplant from the same parental donor...

Forty-eight lentil-nodulating rhizobia were isolated from soil samples collected from diverse agro-ecological locations in Ethiopia, and characterized based on 76 phenotypic traits. Furthermore, 26 representative strains were selected and characterized using multilocus sequence analyses (MLSA) of core (16S rRNA, recA, atpD, glnII and gyrB) and symbiotic (nodA and nifH) genes. Numerical analysis of phenotypic characteristics showed that the 48 test strains fell into three major distinct clusters. The phylogenetic trees based on 16S rRNA genes showed that they belong to the Rhizobium genus...

One of the pathogenic causes of cutaneous inflammatory pseudotumors is chronic localized fibrosing leukocytoclastic vasculitis (CLFLCV), a vasculitic reaction pattern seen in granuloma faciale (GF), a localized vasculitis, and erythema elevatum diutinum (EED), a generalized vasculitis. Patients with myelodysplastic syndromes (MDSs) are at risk for a diverse spectrum of cutaneous neutrophilic dermatoses such as EED. Herein, we report a 74-year-old man who presented with a large ulcerative, fungating tumor affecting the right flexor ankle caused by CLFLCV...

Legume plants engage in intimate relationships with rhizobial bacteria to form nitrogen-fixing nodules, root-derived organs that accommodate the micro-symbiont. Members of the Nuclear Factor Y (NF-Y) gene family, which have undergone significant expansion and functional diversification during plant evolution, are essential for this symbiotic liaison. Acting in a partially redundant manner, NF-Ys were shown previously to regulate bacterial infection, including selection of a superior rhizobial strain, and to mediate nodule structure formation...

A better understanding of the complex relationship between aging and cancer will provide important tools for the prevention and treatment of neoplasia. In these studies, the hypothesis was tested that aging may fuel carcinogenesis via alterations imposed in the tissue microenvironment. Preneoplastic hepatocytes isolated from liver nodules were orthotopically injected into either young or old syngeneic rats and their fate was followed over time using the dipeptidyl-peptidase type IV (DPPIV) system to track donor-derived-cells...

To assess the role of time-intensity curves (TICs) of the normal peripheral zone (PZ) in the identification of biopsy-proven prostate nodules using contrast-enhanced transrectal ultrasound (CETRUS). This study included 132 patients with 134 prostate PZ nodules. Arrival time (AT), peak intensity (PI), mean transit time (MTT), area under the curve (AUC), time from peak to one half (TPH), wash in slope (WIS) and time to peak (TTP) were analyzed using multivariate linear logistic regression and receiver operating characteristic (ROC) curves to assess whether combining nodule TICs with normal PZ TICs improved the prediction of prostate cancer (PCa) aggressiveness...

BACKGROUND: Given that careful histological examination plays a pivotal role in follicular thyroid carcinoma categorization, we hypothesize that the number of blocks taken at initial specimen review may be associated with survival outcomes of patients initially diagnosed with minimally invasive follicular thyroid carcinoma. METHODS: A total of 162 patients with confirmed minimally invasive follicular thyroid carcinoma were analyzed. The number of tissue blocks taken from each patient was recorded and the number of blocks per each centimeter of tumor was calculated...

A 58-year-old Korean-born woman with a history of seizures and psychiatric issues was found dead at home. Autopsy was notable for large, calcified nodules that had nearly replaced her right temporal lobe. Histologic examination revealed the presence of Paragonimus eggs. This case demonstrates a rare manifestation of an aberrantly migrated lung fluke that resulted in epilepsy and sudden death years after the initial infection.

REVIEW
Jeremy D Murray, Cheng-Wu Liu, Yi Chen, Anthony J Miller
Legumes fix atmospheric nitrogen (N) in a symbiotic relationship with bacteria. For this reason, although legume crops can be low yielding and less profitable when compared with cereals, they are frequently included in crop rotations. Grain legumes form only a minor part of most human diets, and legume crops are greatly underutilized. Food security and soil fertility could be significantly improved by greater grain legume usage and increased improvement of a range of grain legumes. One limitation for the use of legumes as a source of N input into agricultural systems is the fact that the formation of N-fixing nodules is suppressed when soils are replete with n...

BACKGROUND: Mucinous cystic neoplasms (MCNs) of the pancreas present a management conundrum. The majority are benign but all are resected due to their malignant potential. Recent studies have recommended nonsurgical management. In the current study, the authors analyzed the preoperative imaging, cytology, and cyst fluid characteristics of 136 histologically confirmed MCNs to assess predictors of a high-risk (HR) cyst for surgical triage. METHODS: MCNs resected at the Massachusetts General Hospital between 1990 and 2014 formed the study cohort...

RATIONALE: Bronchoscopy is commonly used for the diagnosis of suspicious pulmonary nodules discovered on computed tomographic (CT) imaging of the chest. Procedural CT imaging for bronchoscopy planning is often completed weeks to months before the date of a scheduled bronchoscopy, which may not allow discovery of a decrease in nodule size or resolution before the bronchoscopic procedure. OBJECTIVES: To determine whether same-day CT imaging of the chest discovers partial or total resolution of some lung nodules and thereby reduces unnecessary bronchoscopic procedures...

OBJECTIVES: Intrathyroid metastases from extrathyroid primary tumors are rare. Clinical findings may be subtle, but detection of intrathyroid metastases has improved with sonography. The objective of this study was to evaluate the sonographic appearance of intrathyroid metastases. METHODS: Patients with thyroid masses with cytopathologic features matching those of an extrathyroid primary tumor were retrospectively identified. The appearances of intrathyroid metastases on sonography were reviewed for the following features: size, margin regularity, echogenicity, echotexture, vascularity on power or color Doppler ultrasonography, and the presence or absence of any associated cervical adenopathy...
