Parasite infections cause dramatic anatomical and ultrastructural changes in host plants. Cyst nematodes are parasites that invade host roots and induce a specific feeding structure called a syncytium. A syncytium is a large multinucleate cell formed by cell wall dissolution-mediated cell fusion. The soybean cyst nematode (SCN), Heterodera glycines, is a major soybean pathogen. To investigate SCN infection and the syncytium structure, we established an in planta deep imaging system using a clearing solution ClearSee and two-photon excitation microscopy (2PEM)...

INTRODUCTION: Angiosarcoma is a rare malignant neoplasm with poor prognosis. Angiosarcoma of the scalp is frequently recurs locally, and metastasizes early despite various treatments. The common sites of metastatic are lung, liver, and lymph nodes. Pulmonary metastasis with hemoptysis and pneumothorax is rare but threatening. PRESENTATION OF CASE: A 77-year-old male had recurrent angiosarcoma of the scalp even with post operation radiotherapy. At the same time, recurrent pneumothorax was noted, thus he underwent wedge resection of the right upper lobe of the lung plus pleural biopsy...

REVIEW
Krishnan Ravindran, Te Whiti Rogers, Tanya Yuen, Frank Gaillard
White epidermoids are a rare variant of an intracranial epidermoid cyst that do not exhibit typical 'near- cerebrospinal fluid (CSF)' CT density or MRI intensity. Here, the authors present the case of a 58year old man with an acute onset of aphasia and altered consciousness, due to a large heterogeneous cranial mass in the left frontal region with unusual signal intensity. Subsequent histopathological analysis identified the lesion as an epidermoid cyst.

Cardiac echinococcosis is rare. Its spontaneous course is serious because of the risk of rupture. Its clinical manifestations are variable, often latent and misleading. The diagnosis is sometimes referred to by chest radiography. It is much facilitated by non-invasive imaging techniques in particular transesophageal and transthoracic echocardiography, CT scan and magnetic resonance imaging. The latter through a morphological and topographical analysis accurate diagnosis of hydatid cyst and its relationship to cardiac muscle and surrounding tissue...

The multicellular communities of microorganisms known as biofilms are of high significance in agricultural setting, yet it is largely unknown about the biofilm formed by nitrogen-fixing bacteria. Here we report the biofilm formation by Pseudomonas stutzeri A1501, a free-living rhizospheric bacterium, capable of fixing nitrogen under microaerobic and nitrogen-limiting conditions. P. stutzeri A1501 tended to form biofilm in minimal media, especially under nitrogen depletion condition. Under such growth condition, the biofilms formed at the air-liquid interface (termed as pellicles) and the colony biofilms on agar plates exhibited nitrogenase activity in air...

Proteins with Tetratricopeptide-repeat (TPR) domains are encoded by large gene families and distributed in all plant lineages. In this study, the Soluble NSF-Attachment Protein (SNAP) subfamily of TPR containing proteins is characterized. In soybean, five members constitute the SNAP gene family: GmSNAP18, GmSNAP11, GmSNAP14, GmSNAP02, and GmSNAP09. Recently, GmSNAP18 has been reported to mediate resistance to soybean cyst nematode (SCN). Using a population of recombinant inbred lines from resistant and susceptible parents, the divergence of the SNAP gene family is analysed over time...

Prominent cyst formation is an unusual feature of liposarcoma. We report here a case of dedifferentiated liposarcoma with huge cystic change without preoperative chemo- or radiation therapy. The lesion arose in the retroperitoneum juxtaposed to the right kidney of a 67-year-old woman. She underwent a surgical removal of the retroperitoneal cyst. The cystic tumor contained 1600 mL of old bloody fluid, and its wall was composed of edematous, inflamed or sclerosing fibrous tissue with fatty tissue containing abundant atypical stromal cells, which were immunohistochemically positive for MDM2 and CDK4, and demonstrated MDM2 gene amplification by fluorescence in situ hybridization...

Vomiting is a physical finding that can occur at any age but presents the greatest challenge when it is recurrent in a child. The etiology is varied (Sieunarine and Manmohansingh, 1989; Suzuki, 1982), and recurrent vomiting can be a symptom of life threatening medical or surgical emergencies. Early recognition is mandatory for preventing delay in management and potential complications. Gastric duplication is rare and mostly diagnosed in infancy with only a few cases documented in the medical literature presenting in childhood...

The World Health Organization (WHO) treatment protocols for cystic echinococcosis (CE) are based on the standardized ultrasound (US) classification. This study examined whether the classification reflected the natural history of CE in untreated and albendazole-treated patients. Data were collected during mass US screenings in CE endemic regions among transhumant populations, the Turkana and Berber peoples of Kenya and Morocco. Cysts were classified using the WHO classification. Patient records occurring prior to treatment, and after albendazole administration, were selected...

We report histological appearance of a bronchogenic cyst that was incidentally found in a 78-year-old man who died from drowning related to a traumatic accident. The cyst was found in the posterior edge of the interventricular septum and was monolocular with a 5-mm diameter. The cystic wall was not associated with cartilage or the smooth muscle layer, and was lined by ciliated respiratory epithelium. Immunohistochemistry showed that many of these epithelial cells were positive for cytokeratin 7 and thyroid transcription factor-1...

OBJECTIVE: The degradation of articular cartilage, which characterises osteoarthritis (OA), is usually paired with excessive bone remodelling, including subchondral bone sclerosis, cysts, and osteophyte formation. Experimental models of OA are widely used to investigate pathogenesis, yet few validated methodologies for assessing periarticular bone morphology exist and quantitative measurements are limited by manual segmentation of micro-CT scans. The aim of this work was to chart the temporal changes in periarticular bone in murine OA by novel, automated micro-CT methods...

Feline dysautonomia (FD) is a multiple system neuropathy of unknown aetiology. An apparently identical disease occurs in horses (equine grass sickness, EGS), dogs, rabbits, hares, sheep, alpacas and llamas. Horses with acute EGS have a marked reduction in plasma concentrations of the sulphur amino acids (SAA) cyst(e)ine and methionine, which may reflect exposure to a neurotoxic xenobiotic. The aim of this study was to determine whether FD cats have alterations in amino acid profiles similar to those of EGS horses...

Sclerosing polycystic adenosis (SPA) is a rare benign neoplasm of the salivary gland which resembles the fibrocystic disease of the breast clinically as well as morphologically. This entity has varied morphological presentation on fine needle aspiration. Only a few case reports and occasional case series are found in the literature describing its cytology. Here we are presenting a case of SPA in the parotid gland in a 13-year-old male patient who presented with a slow growing infra-auricular mass since one year without any other symptoms...
