BACKGROUND: Diagnosis of Pompe disease is sometimes challenging because it exhibits clinical similarities to muscular dystrophy. CASE: We describe a case of Becker muscular dystrophy (BMD) with a remarkable reduction in activity of the acid α-glucosidase (GAA) enzyme, caused by a combination of pathogenic mutation and polymorphism variants resulting in pseudodeficiency in GAA. The three-year-old boy demonstrated asymptomatic creatine kinase elevation. Neither exon deletion nor duplication was detected on multiplex ligation-dependent probe amplification (MLPA) of DMD...

Background: Bevacizumab was approved by the FDA for the treatment of recurrent or progressive glioblastoma (GBM). Imaging responses are typically assessed by gadolinium-enhanced MRI. We sought to determine the significance of qualitative diffusion signature (manifest as variable degree of dark signal) on ADC maps in recurrent gliomas after treatment with bevacizumab. Methods: We performed an institutional review board (IRB) approved retrospective study on patients who underwent MRI of the brain after 8 weeks of receiving bevacizumab for recurrent glioma...

Basal cell carcinoma of the umbilicus is very rare. The nodular subtype is the main representative. Giant basal cell carcinomas represent around 1% of all basal cell carcinomas. The hedgehog pathway inhibitor vismodegib is indicated for advanced basal cell carcinoma and CD56-negative immunostaining seems indicative for successful treatment. A 54-year-old man presented a 10 cm × 14 cm large and 4.5 cm deep morphea-form basal cell carcinoma with faint immunohistochemical CD56 expression arising from the umbilicus...

Ochratoxin A (OTA) is one of the most common mycotoxins contaminating feed and foodstuffs. Therefore, a great deal of concern is associated with AFB1 toxicity. In this work, a fast and sensitive fluorescence aptamer biosensor has been proposed for the OTA assay. In the absence of OTA, the OTA aptamer can form a G-quadruplex structure with thioflavin T (ThT) dye, which results in increased fluorescence. After joining OTA, OTA aptamer combines with OTA and the G-quadruplex can be formed. Only faint fluorescence was finally observed when ThT weakly reacts with the quadruplex...

Identification of the yolk sac tumor (YST) component in germ cell tumors (GCT) may prove challenging, and highly sensitive and specific immunohistochemical markers are still lacking. Preliminary data from the literature suggest that HNF1β may represent a sensitive marker of YST. The specificity of HNF1β has not been addressed in GCT. A cohort of 49 YST specimens from 45 patients was designed, occurring either as pure tumors, or as a component of a mixed GCT. Immunohistochemistry was conducted on whole tumor sections using HNF1β...

Tissues of the central nervous system (CNS), including the optic nerve (ON), are considered a-lymphatic. However, lymphatic structures have been described in the dura mater of human ON sheaths. Since it is known that lymphatic markers are also expressed by single non-lymphatic cells, these results need confirmation according to the consensus statement for the use of lymphatic markers in ophthalmologic research. The aim of this study was to screen for the presence of lymphatic structures in the adult human ON using a combination of four lymphatic markers...

An 83-year-old woman was admitted to our hospital because of a space-occupying lesion (SOL) in the liver. Enhanced computed tomography (CT) showed a nodule measuring 20mm in size in the posterosuperior segment of the right hepatic lobe (S7) and another nodule measuring 14mm in size in the anterosuperior segment of the right hepatic lobe (S8). The margins of these nodules showed faint enhancement in the arterial phase and presented as low-density areas in the equilibrium phase. The S8 SOL could not be easily identified using ultrasonography (US)...

PET targeting the translocator protein (TSPO) represents an interesting approach for glioma visualization, as TSPO is highly expressed in tumor cells. We present a 32-year-old man with recurrent glioblastoma after multimodal treatment. PET with the novel TSPO ligand F-GE-180 was performed after reirradiation. Here, the previously reirradiated tumor showed a remaining circular TSPO expression. Moreover, cerebrospinal fluid dissemination was detected by a high focal uptake at the right lateral and at the fourth ventricle, whereas only a faint contrast enhancement was present in MRI...

Poor information is available on the molecular landscape characterizing the carcinogenetic process leading to ampullary carcinoma. MiR-21 is one of the most frequently up-regulated miRNAs in pancreatic adenocarcinoma, a tumor sharing similar molecular features with ampullary adenocarcinomas (AVCs), above all with the pancreatic-biliary type. We profiled, by in situ hybridization (ISH), miR-21 expression in a series of 26 AVCs, 50 ampullary dysplastic lesions (35 low-grade [LG-IEN] and 15 high-grade [HG-IEN]) and 10 normal duodenal mucosa samples...

BACKGROUND: In primary studies with 3 T Magnets, phase sensitive reconstruction of T1-weighted inversion recovery (PSIR) have showed ability to depict the cervical multiple sclerosis (MS) lesions some of which may not be detected by short tau inversion recovery (STIR). Regarding to more availability of 1.5 T MRI, this study was designed to evaluate the eligibility of PSIR in 1.5 T for detection of spinal cord MS lesions. METHOD: In a study between September 2016 till March 2017 the patients with proven diagnosis of MS enrolled to the study...

INTRODUCTION: Although human intrapleural hyperthermic perfusion (HIHP) has achieved excellent palliative effects in metastatic pleural malignancies, the optimum treatment conditions, including inlet temperature and treatment times based on tumor size, have yet to be determined. However, such information is recognized to be critical for treatment planning in clinics. Therefore, the current research aimed to solve these issues. METHODS: Using the finite-element method (FEM), a simplified three-dimensional HIHP model was established and verified according to the temperature data of specific measuring points based on a clinical therapeutic case...

Microcystic meningioma (MM) is a rare subtype of intracranial meningiomas, with clinical and radiologic features not well characterized in the literature. Based on our experience, we propose a classification system of intracranial MMs. We reviewed the medical records, radiographic studies, and operative notes of a group of consecutive patients with intracranial MM. The mean age of the 69 patients was 46.8 ± 10.6 years (range, 21-75 years). Three types of intracranial MMs could be identified. Type 1 MMs presented as a solid lesion, hypointense or isointense on T1WI, hyperintense on T2WI, and homogeneous or heterogeneous enhancement, and were found in 43 patients (67...

A diagnosis of acute monocytic leukemia (AML-M5) based on α-naphthyl butyrate esterase (α-NB) staining has some problems, because AML-M5 leukemic cells often show weak or faint positivity on α-NB staining. In these situations, some cases of AML-M5 tend to be misdiagnosed as AML-M0. Therefore, we evaluated the significance of weak or faint α-NB staining in AML-M5 diagnosed by flow cytometry (FCM). Nineteen AML cases in which leukemic cells were negative for naphthol AS-D chloroacetate esterase staining were studied...

The integration of excitatory and inhibitory synaptic inputs is fundamental to neuronal processing. In the mammalian auditory brainstem, neurons compare excitatory and inhibitory inputs from the ipsilateral and contralateral ear, respectively, for sound localization. However, the temporal precision and functional roles of inhibition in this integration process are unclear. Here, we demonstrate by in vivo recordings from the lateral superior olive (LSO) that inhibition controls spiking with microsecond precision throughout high frequency click trains...

In this work, we study the function of the Medicago truncatula ST4, ST5 and ST6 proteins that belong to a protein family of unknown function characterized by the DUF2775 domain. Thus, we analyse their promoter sequence and activity, their transcript accumulation, and their subcellular location. The analysis of the three promoters showed different combination of cis-acting regulatory elements and they presented different activity pattern. Throughout development only ST6 mRNAs have been detected in most of the stages analysed, while ST4 was faintly detected in the roots and in the flowers and ST5 was always absent...

Epithelial-mesenchymal transition (EMT) is an orchestral and functional change in epithelial cells. Many signaling pathways are involved in EMT, and transforming growth factor-beta (TGF-β) is considered to be one of the most important factors in induction of EMT. In this study, we treated the rat intestinal epithelial cell line (IEC-6) with TGF-β1 as a signaling stimulant. Gross analysis of IEC-6 cells showed typical characteristics of epithelial cells such as cuboidal morphology and cell-cell contact, whereas treatment with TGF-β1 (10 ng·ml-1 ) for 7 days produced robust, spindle-shaped morphology...
