C C Shekell, M J Thomson, R I Miller, J T Mackie
CASE REPORT: A 6-year-old speyed female Bull Arab-cross dog was found to have a small tonsillar nodule. Histological examination revealed a well-differentiated mast cell tumour (MCT). At initial staging, no evidence of concurrent cutaneous or visceral MCTs was found on a complete blood count, a single lateral thoracic radiograph, abdominal ultrasound or cytology of the spleen and regional lymph nodes. A diagnosis of primary tonsillar MCT was made. At 40 months postoperatively, the dog is alive with no evidence of gross tumour progression, in contrast to some previous reports of rapid disease progression and metastasis in dogs with primary oral MCTs...

PURPOSE: The aim of this study was to establish whether endoplasmic reticulum (ER) stress is involved in osteogenic differentiation of periodontal ligament cells (PDLCs) and to better understand the mechanism of PDLCs osteogenic differentiation. METHODS: PDLCs were isolated from extracted teeth and cultured in presence or absence of osteogenic medium, which can induce osteogenic differentiation of PDLCs. Alkaline phosphatase and alizarin red S staining were performed to characterize the osteogenic differentiation of PDLCs...

Histone deacetylases (HDAC) plays important roles in the post-translational modifications of histone cores as well as non-histone targets. Many of them are involved in key inflammatory processes. Despite their importance, whether and how HDAC9 is regulated under inflammatory conditions remains unclear. The aim of this study was to evaluate the effects of HDAC9 under chronic inflammation condition in human periodontal ligament stromal cell (PDLSCs) and to explore the underlying regulatory mechanism. PDLSCs from healthy or periodontitis human tissue was compared...

The Burkholderia cepacia complex is a group of 22 species, which are known as opportunistic pathogens in immunocompromised people, especially those suffering from cystic fibrosis. It is also found in nosocomial infections and is difficult to eradicate due to intrinsic resistance to several antibiotics. The species have large genomes (up to 9 Mbp), distributed into 2-5 replicons. These features significantly contribute to genome plasticity, which makes them thrive in different environments like soil, water, plants or even producing nodules in legume plants...

The Liver Imaging Reporting and Data System (LI-RADS) standardizes the interpretation and reporting of imaging examinations in patients at risk for hepatocellular carcinoma (HCC). For focal liver observations it assigns categories (LR-1 to 5, LR-M, LR-TIV), which reflect the relative probability of benignity or malignancy of the respective observation. The categories assigned are based on major and ancillary image features, which have been developed by the American College of Radiology (ACR) and validated in many studies...

REVIEW
Consolato Sergi, Aneesh Dhiman, Jo-Ann Gray
The primary indication of fine-needle aspiration cytology of the head and neck region is a thyroid nodule or a mass located in the cervical area or the head. Although a thyroid nodule may raise the suspicion of malignancy, less than one in 20 cases results in a carcinoma. In addition, the list of differential diagnoses is quite different according to the age of the patient. A number of benign lesions, such as branchial cysts, sialadenosis, and sialoadenitis are often seen in childhood and youth. The malignant lesions that are on the top of the list of a pediatric mass of the head and neck (H&N) region include rhabdomyosarcoma, neuroblastoma, and papillary carcinoma of the thyroid gland...

Pleomorphic adenoma (PA) of the submandibular gland is known to have a very low recurrence rate. The aim of this study was to investigate the histopathological and capsular characteristics of submandibular gland PA, looking for any differences between submandibular PA and the reported data for PA of the parotid gland as possible explanation for its low recurrence rate. We reviewed 72 submandibular gland PAs resected at our center between 2000 and 2016. Patient age ranged from 14 to 77 years (mean, 47.2). At least follow (range, 12 to 170 months; mean, 82), none of the 72 patients developed a local recurrence...

OBJECTIVE: The anticancer effect of myo-inositol (MI) is catching researchers' attention worldwide. Thyroid nodules (TNs) have been detected by ultrasound (US) in up to 76% of the general population and, although most of them are benign, thyroid cancer is the most common malignancy of the endocrine system. PATIENTS AND METHODS: A retrospective, observational study was conducted in 642 patients with suspected hypothyroidism undergoing US. The analysis was addressed exclusively to patients with subclinical hypothyroidism (SCH) or thyroid-stimulating hormone (TSH) levels borderline associated to TNs classified as class I and II; 1 group (control, no...

PURPOSE: The resistance/nodulation/cell division (RND) family multidrug efflux pump, OqxAB, has been identified as one of the leading mechanisms of plasmid-mediated quinolone resistance and has become increasingly prevalent among Enterobacteriaceae in recent years. However, oqxAB genes have not yet been reported in Enterococcus isolates. The aim of the present study was to identify the oqxAB genes and investigate their prevalence among Enterococcus from swine manure in China. METHODOLOGY: The oqxAB genes were screened in 87 Enterococcus isolates by PCR...

Alders (Alnus spp.) often dominate at nutrient-poor sites by symbiotic relations with atmospheric nitrogen-fixing bacteria. However, little is known about quantitative relationships between root nodule as a nitrogen acquisition organ and leaf as a carbon acquisition organ. To examine carbon allocation, nitrogen acquisition and net production in nutrient-poor conditions, we examined allocation patterns among organs of shrub Alnus fruticosa at a young 80-year-old moraine in Kamchatka. Slopes of double-log allometric equations were significantly smaller than 1...

Identifying and localizing of deep pulmonary nodules are among the main challenges that thoracic surgeons face during operations, particularly in thoracoscopic procedures. To facilitate this, we have tried to introduce a non-invasive and safe method by measuring the lung electrical bio-impedance spectrum with a four-electrode array sensor. To study the feasibility of this method, since any change in the depth or diameter of the nodule in the lung tissue is not practical, we used the finite element modeling of the lung tissue and pulmonary nodule to allow changes in the depth and diameter of the nodule, as well as the distance in between the injection electrodes...

Primary thyroid lymphoma, although a rare malignancy, can arise in common chronic inflammatory conditions such as Hashimoto's thyroiditis. Incidental finding of a thyroid nodule with chronic thyroid inflammation warrants further investigation. Early detection of malignancy can play a vital role in improved outcomes. We report a case of a 60-year-old male who presented to the clinic for a routine visit. An enlarged, firm, non-tender thyroid gland was appreciated on exam with high thyroid stimulating hormone (TSH) level...

We present a case of Majocchi granuloma, a deep folliculitis, on the lip of a healthy 41-year-old man. The patient was successfully treated with systemic and topical antifungal medications. Correct diagnosis of this rare condition is needed, since misdiagnosis as an inflammatory dermatitis and treatment using topical corticosteroids can lead to dissemination of the infection.

Rheumatic fever (RF) is an autoimmune disease associated with group A β-hemolytic streptococcal infection, in the course of which the patient develops carditis, arthritis, chorea, subcutaneous nodules and erythema marginatum. Rheumatic fever diagnosis is based on the Jones criteria, developed in 1944, then revised twice by the American Heart Association (AHA), in 1992 and recently in 2015. The last revision of the Jones criteria consists mainly in the supplementation of the major criteria with echocardiographic examination, the introduction of a concept of subclinical carditis and the isolation of low, medium and high risk populations among the patients...

Serine proteases and serine protease homologs are involved in the prophenoloxidase (proPO)-activating system leading to melanization. The Bombyx mori serine protease homolog BmSPH-1 regulates nodule melanization. Here, we show the dual role of BmSPH-1 in the development and immunity of B. mori. BmSPH-1 was expressed in hemocytes after molting and during the larval-pupal transformation in normal development. In contrast, following infection, BmSPH-1 was expressed in hemocytes and cleaved in the hemolymph, which resulted in the induction of PO activity...
