BACKGROUND: Homozygous deletion of 9p21 detected by fluorescence in situ hybridization (FISH) and loss of BRCA1-associated protein 1 (BAP1) expression detected by immunohistochemistry (IHC) are useful for the differentiation between malignant pleural mesothelioma (MPM) and reactive mesothelial hyperplasia. The authors previously described that IHC expression of the protein product of the methylthioadenosine phosphorylase (MTAP) gene, which is localized in the 9p21 chromosomal region, was correlated with the deletion status of 9p21 FISH in MPM tissues...

To address the current dearth of clinically relevant publications regarding ovariohysterectomy (OVH) in the domestic pot-bellied pig (PBP), the present study aims to report prevalence of uterine lesions, intraoperative complications, and short and long-term survival in this species (n=298). Prevalence of lesions included uterine neoplasia 11.4 per cent (34/298), pyometra 1.6 per cent (5/298) and cystic endometrial hyperplasia 5 per cent (15/298). Pigs at least six years of age were statistically more likely to have a uterine lesion (less than P=0...

Thyroid carcinoma (TC) is the most common endocrine neoplasm. The risk of TC as a second primary malignancy (SPM) of breast cancer is significantly increased. Bisphenol A (BPA) is a widely contacted xenoestrogen and increases susceptibility to breast cancer through binding to estrogen receptor alpha (ERα). However, the effect of BPA on thyroid carcinogenesis has not been fully demonstrated. This present study aimed to characterize the effects of BPA on the development of TC using a Fischer 344 (F344) rat model...

Using bicalutamide-androgen receptor (AR) DNA binding domain-ligand binding domain as bait, we observed enrichment of FxxFY motif-containing peptides. Protein database searches revealed the presence of receptor-interacting protein kinase 1 (RIPK1) harboring one FxxFY motif. RIPK1 interacted directly with AR and suppressed AR transactivation in a dose-dependent manner. Domain mapping experiments showed that the FxxFY motif in RIPK1 is critical for interactions with AR and the death domain of RIPK1 plays a crucial role in its inhibitory effect on transactivation...

Gut microbiota facilitate many aspects of human health and development, but dysbiotic microbiota can promote hyperplasia and inflammation and contribute to human diseases such as cancer. Human patients infected with the gastric cancer-causing bacterium Helicobacter pylori have altered microbiota; however, whether dysbiosis contributes to disease in this case is unknown. Many H. pylori human disease phenotypes are associated with a potent virulence protein, CagA, which is translocated into host epithelial cells where it alters cell polarity and manipulates host-signaling pathways to promote disease...

Cathelicidin has been reported to be multifunctional. The current study aimed to investigate the influences of exogenous cathelicidin-related antimicrobial peptide (CRAMP) on inflammatory responses in different disease models. In OVA-induced allergic airway inflammation, CRAMP significantly enhanced the infiltration of inflammatory cells and accumulation of proinflammatory Th2 cytokine IL-13 and IL-33 in bronchial alveolar lavage fluid (BALF), exacerbated lung tissue inflammation and airway goblet cell hyperplasia, and elevated OVA-specific IgE level in serum...

Aims: Chronic kidney disease (CKD) is a powerful independent risk factor for cardiovascular events, including vein graft failure. Because CKD impairs the clearance of small proteins, we tested the hypothesis that CKD exacerbates vein graft disease by elevating serum levels of critical cytokines that promote vein graft neointimal hyperplasia. Methods and results: We modelled CKD in C57BL/6 mice with 5/6ths nephrectomy, which reduced glomerular filtration rate by 60%, and we modelled vein grafting with inferior-vena-cava-to-carotid interposition grafting...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving chronic dialysis therapy. Although cinacalcet can control parathyroid function and bone turnover, preventing ectopic calcification remains challenging. Cinacalcet can also suppress PTH secretion due to parathyroid carcinoma in the same way as it does for parathyroid hyperplasia in the uremic condition. We present a case of parathyroid carcinoma partially controlled by cinacalcet, in which tumorous calcinosis was successfully resolved by total parathyroidectomy...

Pulmonary hypertension (PH) is characterized by increased vasoconstriction and smooth muscle cell hyperplasia driving pathological vascular remodeling of arterial vessels. In this short review, we discuss the primary source of reactive oxygen species (ROS) and nitric oxide (NO) relevant to PH and the mechanism by which dysregulation of their production contributes to PH. Specifically, hypoxia-induced PH is associated with diminished endothelial nitric oxide synthase (eNOS)-derived NO production and increased production of superoxide (O2(•-)) through eNOS uncoupling and defective mitochondrial respiration...

REVIEW
Omid Yassaie, Joshua A Silverman, Peter J Gilling
Aquablation is a novel technique for the surgical management of bladder outlet obstruction secondary to benign prostatic hyperplasia. Following first-in-man studies, a multicenter trial was conducted with results now out to 1 year. Aquablation resulted in a mean International Prostate Symptom Score improvement of 16 points (p < 0.01) and a mean maximum urinary flow rate increase from 8.7 to 18.3 ml/s (p < 0.01) at 12 months. Due to the precise prostate mapping, aquablation has also demonstrated favorable sexual and urinary outcomes with no new erectile dysfunction, retrograde ejaculation, or urinary incontinence as often experienced with other techniques...

REVIEW
Joseph M Kuebker, Nicole L Miller
PURPOSE OF REVIEW: Holmium laser enucleation of the prostate (HoLEP) is a proven technique to alleviate bladder outlet obstruction (BOO) from benign prostatic hyperplasia (BPH). Herein, we review factors relevant to selecting patients who will benefit from this procedure and expected outcomes. RECENT FINDINGS: New randomized trials have validated the excellent outcomes achieved by HoLEP in the management of BOO from BPH. Its success has been reproduced in a diverse array of patients including those on anticoagulation, with detrusor underactivity/acontractility, prostate cancer, and in the retreatment setting...

Children with congenital adrenal hyperplasia (CAH) are exposed to high levels of testosterone in utero often resulting in nontypical genitalia at birth for girls. The purpose of this analysis, which draws on data from a larger study, was to examine, based on the gender of the child, the family experiences of having a child with CAH. Sixteen parents were interviewed, and comparisons were made across all categories coded in the parents' interviews to examine similarities and differences in the experiences of families based on the child's gender...

The type of tissue response to implant by-products can be determined by examination of periprosthetic tissues. However, little is known about the most suitable location for tissue sampling. The main goal of this study was to evaluate the extent of variability in tissue response in relation to location of tissue sampling, implant fixation, age and sex in total joint arthroplasties with metal-on-polyethylene or ceramic-on-polyethylene bearing pairs. We processed 236 histology slides from 21 patients and focused on the association between the location of tissue samples and histological features...
