The anti-inflammatory effects of boldine and reticuline isolated from Litsea cubeba were evaluated by using xylene-induced ear edema and carrageenan-induced paw edema in mice and rats. Our results demonstrated that intragastric administration with boldine and reticuline significantly mitigated ear weight in mice and decreased paw volume in rats. A combination administration of boldine (0.5 mg/kg) + reticuline (0.25 mg/kg) resulted in a potentiated inhibition in these two models. In parallel, boldine or reticuline reduce the infiltration of neutrophil leukocytes in rat paw tissue, respectively, and the combination of the two groups performed a better anti-inflammatory activity as shown in histopathologies...

The aggregation of α-synuclein is linked directly to the histopathology of Parkinson's disease (PD). However, several missense mutations present in the α-synuclein gene (SNCA) have been known to be associated with PD. Several studies have highlighted the effect of SNCA mutations on the α-synuclein aggregation, but their pathological roles are not completely established. In this study, we have focused on the effects of the recently discovered α-synuclein missense mutants (H50Q and G51D) on the aggregation using computational approaches...

ETHNOPHARMACOLOGICAL RELEVANCE: The dried ripe seeds of Nux Vomica (Strychnos nux-vomica L.), a traditional Chinese medicine, have been used to treat multifarious symptoms. However, the clinical applications of Nux Vomica are limited by its severe toxicity. In this study, Nux Vomica was subjected to nuclear magnetic resonance (NMR) metabonomics and pathological examination to determine relevant biomarkers in target organs and to explain the underlying toxicity mechanism. MATERIALS AND METHOD: Thirty-six male Sprague-Dawley rats were randomly divided into three groups of twelve rats...

BACKGROUND: Patients with hypersensitivity pneumonitis are at risk of developing pulmonary fibrosis, which is associated with reduced survival. In families with multiple affected members, individuals might be diagnosed as having idiopathic pulmonary fibrosis (IPF) or chronic (fibrotic) hypersensitivity pneumonitis, which suggests these disorders share risk factors. We aimed to test whether the genomic risk factors associated with the development and progression of IPF are also associated with the development of fibrosis and reduced survival in people with chronic hypersensitivity pneumonitis...

An 18-year-old man presented with spontaneous severe epigastric pain, progressing and radiating to back since 3 days. It was associated with epigastric tenderness, bilious vomiting and jaundice. He had been intermittently experiencing these symptoms for the last 1 year. No known comorbid. Ultrasound showed a poorly visualised heterogeneous focus at porta hepatis; considering poor visualisation, this might represent an enlarged calcified lymph node or cystic duct calculus causing extrinsic compression or a large sludge ball within the common bile duct (CBD), leading to dilatation of common hepatic duct and intrahepatic biliary system...

PURPOSE: The staging of multiple pulmonary adenocarcinomas requires the distinction of intrapulmonary metastasis (IPM) from multiple primary lung cancers (MPLC). This can be challenging in some patients, and the addition of data from oncogenic driver mutations in these tumors may be helpful in this determination. PROCEDURES: As a proof of principle, molecular driver results from primary tumors and their metastases in 45 patients were compared (cohort 1). Then, 69 patients with a total of 154 synchronous or metachronous lung carcinomas were identified, with pathologic findings compared to oncogenic driver mutation...

A variety of syndromic diseases such as Marfan syndrome, Loeys-Dietz syndrome, and bicuspid aortic valve with aneurysm along with risk factors of smoking and hypertension result in ascending aortic aneurysms and dissections. Historically, a complicated variety of terms have been used to describe a range of histopathologies that are present in resected specimens. As a result, no consistent patterns of histopathology have been reported. We used the recent Society for Cardiovascular Pathology/Association for European Cardiovascular Pathology consensus statement on nomenclature and diagnostic criteria for noninflammatory aortic disease to blindly evaluate 148 surgically resected specimens...

Sodium valproate (VP) is an important antiepileptic drug, although it can produce deleterious hepatotoxic reactions. Diallyl trisulfide (DATS) is the principle component of garlic oil that possesses antioxidant properties. This study explored the potential hepatoprotective activity of DATS against VP-induced hepatic damage and its underlying mechanisms. In addition, the study assessed the effect of DATS on VP antiepileptic activity. Rats were given DATS once daily at two different doses along with VP for 2 weeks...

High-grade dysplasia (HGD) of the cystic duct margin without evidence of concurrent malignancy is a rare occurrence. We present a case of a 36-year-old woman who developed gallstone pancreatitis and subsequently underwent a laparoscopic cholecystectomy. On histopathology, she was found to have HGD at the cystic duct margin. Following evaluation, she underwent excision of the cystic duct remnant with no malignancy being present on final pathology. We present this case to discuss the management of cystic duct dysplasia in the absence of gallbladder malignancy...

CONTEXT: Extra-gastrointestinal stromal tumors (E-GIST) presenting in the liver are exceedingly rare and raise difficult diagnostic and therapeutic challenges. METHODS: We report on two cases of liver E-GIST with different clinical presentations. We describe their clinical and imaging features, their histopathological and molecular characteristics, their treatment and their course. RESULTS: The first case was that of a 56-year-old male presenting with a 10-cm liver mass; the initial diagnosis, made in 1986 from a biopsy sample, was leiomyosarcoma; liver transplantation was performed in 1987; no extra-hepatic tumor was found; the course was uneventful until 1999, when tumor recurrence was diagnosed along the initial biopsy route; after reevaluation of available material, the definitive pathological diagnosis was GIST; imatinib treatment resulted in major response; the patient died of end-stage kidney disease 22 years after the initial diagnosis and 9 years after tumor recurrence...

BACKGROUND: Accurate tissue sampling in nonenhancing (NE) gliomas is a unique surgical challenge due to their intratumoral histological heterogeneity and absence of contrast enhancement as a guide for intraoperative stereotactic guidance. Instead, T2/fluid-attenuated inversion-recovery (FLAIR) hyperintensity on MRI is commonly used as an imaging surrogate for pathological tissue, but sampling from this region can yield nondiagnostic or underdiagnostic brain tissue. Sodium fluorescein is an intraoperative fluorescent dye that has a high predictive value for tumor identification in areas of contrast enhancement and NE in glioblastomas...

Aim To determine the serum levels of matrix metalloproteinase 9 (MMP-9) concentration and their association with the stage and histopathologic sizes of colorectal cancer (CRC). Methods One hundred and two patients with clinically diagnosed and histologically confirmed colorectal cancer ready for surgical treatment were included in the study. In each patient, preoperative peripheral venous blood samples were taken for determination of the concentration of MMP-9 using ELISA immunoassay test. Resected tumour specimens were studied pathologically according to the criteria of the TNM classification...

Solid tumors in childhood are extremely rare entities, which are usually treated in specialized centers. Diagnosis and therapy are carried out according to a joint European protocol, whereby the pathological evaluation and therapy are carried out according to international guidelines. For the correct diagnosis and/or therapy of most tumors, analysis of specific genetic changes is mandatory; therefore, tumors have to be adequately sampled for parallel genetic analysis during the pathological work-up. A second opinion reference of the histopathological assessment is part of the international guidelines...

RATIONALE: Usual interstitial pneumonia (UIP) is the histopathologic hallmark of idiopathic pulmonary fibrosis. While UIP can be detected by high-resolution computed tomography (HRCT) of the chest, HRCT results are frequently inconclusive, and pathology from transbronchial biopsy (TBB) has poor sensitivity. Surgical lung biopsy (SLB) may be necessary for a definitive diagnosis. OBJECTIVES: To develop a genomic classifier in tissue obtained by TBB that distinguishes UIP from non-UIP, trained against central pathology as the reference standard...
