Probiotics have been proposed as alternatives to pharmacological products in several medical conditions including the modulation of obesity, which is frequently associated with poor semen quality. However, effects of probiotics on male fertility have been less investigated. This study assessed the effect of Lactobacillus rhamnosus PB01 (DSM-14870) on sperm kinematic parameters in Normal-weight (NW) and diet-induced obese (DIO) models. NW and DIO C57BL/6NTac mice were divided into two subgroups with or without a single daily dose (1x109CFU) of L...

The acetabular labrum of the hip (ALH) is recognized as a clinically important structure, but knowledge about the pathophysiology of this fibrocartilage is scarce. In this prospective study we determined the prevalence of ALH calcification in patients with end-stage osteoarthritis (OA) and analyzed the relationship of cartilage calcification (CC) with hip pain and clinical function. Cohort of 80 patients (70.2±7.6years) with primary OA scheduled for total hip replacement. Harris Hip Score (HHS) was recorded preoperatively...

Papillary lesions of the breast range from benign to atypical to malignant. Although papillomas without frank cancer are benign, their management remains controversial. When a core needle biopsy of a lesion yields a diagnosis of intraductal papilloma with atypia, excision is generally recommended to rule out a concurrent malignant neoplasm. For intraductal papillomas without atypia, however, recommendations for excision versus observation are variable. The aims of this study are to evaluate the rate of concurrent malignancies for intraductal papilloma diagnosed on core needle biopsy and to assess the long-term risk of developing cancer after the diagnosis of a papillary lesion...

Atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), and lobular carcinoma in situ (LCIS) are commonly seen on breast core needle biopsy (CNB). Many institutions recommend excision of these lesions to exclude malignancy. A retrospective chart review was performed on patients who had ADH, ALH, or LCIS on breast CNB from 1/1/08 to 12/31/10 who subsequently had surgical excision of the biopsy site. Study objectives included determining upgrade to malignancy at surgical excision, identification of predictors of upgrade, and validation of a recently published predictive model...

INTRODUCTION: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign reactive inflammatory lesion. The usual presentation is a single or multiple skin nodules of the head and neck. Involvement of the hand is very rare and there have been no comprehensive reviews on ALHE of the upper limb. In this paper, we report on a case involving the common digital artery of the hand. We also review the literature and offer two classification systems for upper limb lesions: One according to the primary structure involved, and the other according to the presentation with either single or multiple lesions...

INTRODUCTION: Contralateral reduction mammaplasty is regularly included in the treatment of breast cancer patients. We analyzed the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens of women with previous breast cancer. We also analyzed if timing of reduction mammaplasty in relation to oncological treatment influenced the incidence of abnormal findings, and compared if patients with abnormal contralateral histopathology differed from the study population in terms of demographics...

We used DFT to study the energetics of the decomposition of alane, AlH3, on the Si(0 0 1) surface, as the acceptor complement to PH3. Alane forms a dative bond with the raised atoms of silicon surface dimers, via the Si atom lone pair. We calculated the energies of various structures along the pathway of successive dehydrogenation events following adsorption: AlH2, AlH and Al, finding a gradual, significant decrease in energy. For each stage, we analyse the structure and bonding, and present simulated STM images of the lowest energy structures...

Cancer stem cells are responsible for tumor recurrence and metastasis. A new highly reproducible procedure for human breast cancer MCF-7 stem cells (BCSC) isolation and selection was developed by using a combination of hypoxia/hypoglycemia plus taxol and adriamycin for 24h. The BCSC enriched fraction (i) expressed (2-15 times) the typical stemness protein markers CD44+, ALDH1A3 and Oct 3/4; (ii) increased its clonogenicity index (20-times), invasiveness profile (>70%), migration capacity (100%) and ability to form mammospheres, compared to its non-metastatic MCF-7 counterpart...

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a distinctive lymphocyte rich vasoformative proliferation comprising epithelioid-appearing endothelial cells with partially canalized capillary vessels in a lymphohistiocytic and eosinophil rich environment. ALHE presents clinically as single or multiple pink-brown dome-shaped papules or nodules, most commonly on the ear and peri-auricular area, followed by the face, and scalp. ALHE involving the subungual unit is rare with only 5 previously reported cases and all involved the underlying bone...

BACKGROUND: The peripheral leukocyte count is a biomarker of inflammation and is associated with human all-cause mortality. Although causes of acute leukocytosis are well-described, chronic environmental determinants of leukocyte number are less well understood. OBJECTIVES: We investigated the relationship between house dust endotoxin concentration and peripheral leukocyte counts in human subjects. METHODS: The endotoxin–leukocyte relationship was evaluated by linear regression in the National Health and Nutrition Examination Survey (NHANES) 2005–2006 (n=6,254) and the Agricultural Lung Health Study (ALHS; n=1,708)...

Angiolymphoid Hyperplasia with Eosinophilia (ALHE) is an atypical vascular tumour occurring primarily in the head and neck area, which must be distinguished from Kimura's disease. The lesions can appear as single or multiple grouped intradermal papules or subcutaneous nodules. We report a rare case of ALHE in a 57-year-old female with a large lesion of three nodules involving the right occipital artery which had a long term evolution and we treated it by surgical excision. The definitive histopathological diagnosis was ALHE...

Lymphoproliferative diseases (LPDs) of the ocular adnexa encompass the majority of orbital diseases and include reactive follicular hyperplasia (RFH), atypical lymphoid hyperplasia (ALH), and mucosa-associated lymphoid tissue lymphoma (MALToma). Lymphoid follicles (LFs) are usually observed during the histological examination of LPDs. Currently, because there is a lack of specific clinical signs and diagnostic immunohistochemical biomarkers, it is difficult for pathologists to distinguish MALToma from ocular RFH and ALH, which makes the clinical management of these conditions difficult...

Oxidative damage contributes to human diseases of aging including diabetes, cancer, and cardiovascular disorders. Reactive oxygen species resulting from xenobiotic and endogenous metabolites are sensed by a poorly understood process, triggering a cascade of regulatory factors and leading to the activation of the transcription factor Nrf2 (Nuclear factor-erythroid-related factor 2, SKN-1 in Caenorhabditis elegans). Nrf2/SKN-1 activation promotes the induction of the phase II detoxification system that serves to limit oxidative stress...

Seminal plasma removal is routine in goat sperm cryopreservation protocols. The classical washing procedure designed to accomplish this usually leaves the pellet resulting from use of this procedure contaminated with dead sperm, debris, and cells other than sperm. This contamination negatively affects viability of sperm after cryopreservation. The present research was conducted to compare the effect on chilled and frozen-thawed goat sperm of the classical washing method to that of a selective washing method involving density gradient centrifugation (DGC)...
