BACKGROUND: The white-backed planthopper (WBPH) Sogatella furcifera Horváth, the brown planthopper (BPH) Nilaparvata lugens, and the small brown planthopper (SBPH) Laodelphax striatellus (Hemiptera: Delphacidae) are rice pests that damage rice plants by sap-sucking and by transmitting viruses. Host-seeking behavior involves chemosensory receptor genes, which include odorant receptors (ORs), ionotropic receptors (IRs) and gustatory receptors (GRs). RESULTS: We used genome and transcriptome data to identify 141 ORs, 28 GRs and 25 IRs in BPH, 135 ORs, 18 GRs and 16 IRs in WBPH and 37 ORs, 14 GRs and 6 IRs in SBPH...

PURPOSE OF REVIEW: Holmium laser enucleation of the prostate (HoLEP) has been a mainstay therapy for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostate hyperplasia (BPH) for nearly 20 years. We briefly review current and sentinel publications that provide outcomes data after HoLEP. RECENT FINDINGS: Current literature continues to support HoLEP as a versatile and durable surgical option for men with LUTS secondary to BPH. Despite evidence supporting durable symptom relief beyond 10 years even in large prostate glands, HoLEP is still not widely available to all patients...

We studied the association of the serum levels of the microRNA family members miR-320a/-b/-c with clinico-pathological data to assess their applicability as diagnostic biomarker in prostate cancer (PCa) patients. The levels of miR-320a/-b/-c in 3 groups were evaluated by qRT-PCR (145 patients with PCa, 31 patients with benign prostatic hyperplasia (BPH) and 19 healthy controls). The levels of the three family members of miR-320 were directly correlated within each group ( P < 0.001), but they differed significantly among the three groups ( P < 0...

The mechanisms involved in the development of benign prostatic hyperplasia (BPH) are poorly understood. One potential mechanism involved in BPH pathogenesis may involve altered expression of genes related to apoptosis and proliferation because reduced cell death and increased proliferation are thought to contribute to prostatic enlargement. This study examined the expression of B-cell lymphoma 2 (BCL-2) and B-cell lymphoma-extra large (BCL-XL), two important anti-apoptosis factors that are also capable of inhibiting cell proliferation via accelerated G1 arrest or delayed G1/S transition, using immunostaining in simple prostatectomy BPH specimens from patients naïve to androgen manipulation...

Preeclampsia (PE), a hypertensive disease of pregnancy, is a leading cause of fetal and maternal morbidity/mortality. Early angiogenic and inflammatory disturbances within the placenta are thought to underlie the development of the maternal PE syndrome and poor pregnancy outcomes. However, the exact etiology remains largely unknown. Here, we use the BPH/5 mouse model of PE to elucidate the way in which inflammation early in pregnancy contributes to abnormal expression of angiogenic factors at the maternal-fetal interface...

Bone metastasis from prostate cancer (PCa) can occur years after prostatectomy, due to reactivation of dormant disseminated tumor cells (DTC) in the bone, yet the mechanism by which DTC are initially induced into a dormant state in the bone remains to be elucidated. We show here that the bone microenvironment confers dormancy to C4-2B4 PCa cells, as they become dormant when injected into mouse femurs but not under the skin. Live-cell imaging of dormant cells at the single cell level revealed that conditioned medium from differentiated, but not undifferentiated osteoblasts induced C4-2B4 cellular quiescence, suggesting that differentiated osteoblasts present locally around the tumor cells in the bone conferred dormancy to PCa cells...

Background: Benign prostatic hyperplasia (BPH) is a prevalent disease associated with lower urinary tract symptoms (LUTS). The standard of care for moderate-to-severe LUTS unresponsive to pharmacological treatment is the transurethral resection of the prostate (TURP). However, this intervention is not exempt from complications. Prostatic artery embolization (PAE) has been described as a new, effective and safe procedure for the treatment of LUTS secondary to BPH. To date, only one clinical trial has been published on the use of PAE for LUTS, but the study was methodologically flawed in terms of safety monitoring...
