The development of the mammary gland is a hormone-regulated event. Several factors can dysregulate its growth and make the gland more susceptible to cellular transformation. Among these factors, perinatal exposure to xenoestrogens and hormone replacement therapy has been associated with increased risk of developing breast cancer. Here, we assessed the effects induced by estrogen replacement therapy (ERT) in ovariectomized (OVX) middle-aged rats and whether perinatal exposure to diethylstilbestrol (DES) or bisphenol A (BPA) modified these effects in the mammary gland...

BACKGROUND AND AIM: Obese patients with chronic inflammation in white adipose tissue (WAT) have an increased risk of developing non-alcoholic steatohepatitis (NASH). The C-C chemokine receptor-2 (CCR2) has a crucial role in the recruitment of immune cells to WAT and liver, thereby promoting the inflammatory component of the disease. Herein, we examined whether intervention with propagermanium, an inhibitor of CCR2, would attenuate tissue inflammation and NASH development. METHODS: Male C57BL/6J mice received a high-fat diet (HFD) for 0, 6, 12 and 24 weeks to characterize the development of early disease symptoms of NASH, i...

Breast magnetic resonance (MR) imaging is the only breast imaging modality that consistently encompasses extramammary structures in the thorax and upper abdomen. Incidental extramammary findings on breast MR images of patients with a history of breast cancer or other malignancies are significantly more likely to be malignant and may affect staging and treatment. An understanding of the frequency, distribution, and context of extramammary findings on breast MR images and a familiarity with common and uncommon sites of breast cancer metastasis inform the differential diagnosis and prompt the appropriate diagnostic next step, to differentiate benign from malignant findings...

OBJECTIVE: The objective of our study was to review the sonographic features of breast lesions yielding lobular neoplasia (LN) at sonographically guided biopsy, evaluate the surgical pathology outcome of these lesions, and determine if imaging findings or clinical features can be used to predict an upgrade to malignancy. MATERIALS AND METHODS: Of the 8205 sonographically guided breast biopsies (14-gauge cores) performed from 2007 through 2014, 22 yielded a diagnosis of LN, which means that LN was the most severe pathologic lesion...

: Hepatocyte apoptosis in non-alcoholic steatohepatitis (NASH) can lead to fibrosis and cirrhosis, which permanently damage the liver. Understanding the regulation of hepatocyte apoptosis is therefore important to identify therapeutic targets that may prevent the progression of NASH to fibrosis. Recently, increasing evidence has shown that lncRNAs are involved in various biological processes and that their dysregulation underlies a number of complex human diseases. By performing gene expression profiling of 4,383 lncRNAs in 82 liver samples from individuals with NASH (n=48), simple steatosis but no NASH (n=11) and healthy controls (n=23), we discovered a liver-specific lncRNA (RP11-484N16...

BACKGROUND & AIMS: No treatment for nonalcoholic fatty liver disease (NAFLD) has been approved by regulatory agencies. We performed a randomized controlled trial to determine whether 52 weeks of cysteamine bitartrate delayed release (CBDR) reduces the severity of liver disease in children with NAFLD. METHODS: We performed a double-masked trial of 169 children with NAFLD Activity Scores ≥ 4 at 10 centers. From June 2012 to January 2014, the patients were randomly assigned to receive CBDR or placebo twice daily (300 mg for ≤65 kg, 375 mg for >65-80 kg, 450 mg for >80 kg) for 52 weeks...

Classification of body cavity effusions is an important step in the investigation and diagnosis of disease in cats. Feline inflammatory effusions are often highly proteinaceous and viscous, which can cause clumping of white cells and subsequently inaccurate nucleated cell counts (NCCs) using automated and manual methods. Microscopic assessment of cellularity can also be difficult given the variable thickness of smears and cell clumping, which skews white cell distribution. The ADVIA 120 uses 2 white cell-counting channels, the basophil/lobularity (WBC/baso) and differential/peroxidase channels, which can provide quite different results in highly viscous feline samples and often disagree with smear assessment of cellularity...

PURPOSE: In contemporary practice, 5% of women with non-malignant needle biopsies of screen-detected lesions still require diagnostic open biopsy (OBx). Our aims are to (i) capture a snapshot of the contemporary indications for OBx in screen-detected lesions; (ii) determine upgrade rates to malignancy (DCIS or invasive cancer); (iii) identify indications with sufficiently low upgrades to justify avoidance of OBx and (iv) propose plausible non-surgical alternatives. METHODS: Between Jan 2005 and Dec 2014, women assessed for a screen-detected lesion and recommended for OBx are included...

The ingestion of pods of Enterolobium contortisiliquum is associated with digestive disturbances, photosensitivity and abortion in domestic ruminants. This experiment was designed to test the hypothesis that digestive disturbances in this toxicosis are really caused by acute ruminal acidosis. Three sheep fed large doses (10-15 g/kg/body weight [bw]) of E. contortisiliquum pods developed ruminal acidosis and were treated with sodium bicarbonate to try to control this metabolic disturbance, thus providing additional evidence of the involvement of ruminal acidosis in the pathogenesis of toxicosis...

REVIEW
Pierre Bedossa
Non-alcoholic fatty liver disease (NAFLD) covers a spectrum of lesions ranging from steatosis (Non-alcoholic Fatty Liver or NAFL) to a complex pattern with hepatocellular injury and inflammation (non-alcoholic steatohepatitis; NASH) in the absence of alcohol intake. However, it is increasingly clear that intermediate patterns may exist. The histopathological evaluation of liver biopsy samples is central in the diagnosis of NAFLD and NASH in the absence of sufficiently accurate non-invasive tests because a precise definition of each group is a key issue...

BACKGROUND: Idiopathic granulomatous lobular mastitis (IGLM) is a chronic, non-caseating, inflammatory breast disease of obscure aetiology characterized by multiple masses, abscesses and sinus formation. There is no standard treatment to date, but surgical procedures and systemic corticosteroids are effective in its treatment despite high recurrence rates. PATIENTS AND METHODS: This prospective study including 30 patients with IGLM between November 2012 and May 2016 aimed to investigate the possibility of administration of Rifampicin (300 mg twice daily for a period of 6-9 months) as an alternative therapy for both surgery and corticosteroids in patients with IGLM...

Detailed mapping of clinical dysfunctions to the cerebellar lobules in disease populations is necessary to establish the functional significance of lobules implicated in cognitive and motor functions in normal subjects. This study constitutes the first quantitative examination of the lobular correlates of a broad range of cognitive and motor phenomena in cerebellar disease. We analysed cross-sectional data from 72 cases with cerebellar disease and 36 controls without cerebellar disease. Cerebellar lobule volumes were derived from a graph-cut based segmentation algorithm...

Granulomatous lobular mastitis is a rare inflammatory disease of the breast of unknown etiology. Most present as breast masses in women of child-bearing age. A 29-year-old female presented with a swollen, firm and tender right breast, initially misdiagnosed as mastitis. Core needle biopsy revealed findings consistent with granulomatous lobular mastitis, and cultures were all negative for an infectious etiology. She was started on steroid therapy to which she initially responded well. A few weeks later she deteriorated and was found to have multiple breast abscesses...

In this research, we characterized the histopathological impact of dengue virus (serotype DENV-2) infection in livers of BALB/c mice. The mice were infected with different doses of DENV-2 via intraperitoneal injection and liver tissues were processed for histological analyses and variation was documented. In the BALB/c mouse model, typical liver tissues showed regular hepatocyte architecture, with normal endothelial cells surrounding sinusoid capillary. Based on histopathological observations, the liver sections of BALB/c mice infected by DENV-2 exhibited a loss of cell integrity, with a widening of the sinusoidal spaces...
