Rice (Oryza sativa L.) and the brown planthopper (Nilaparvata lugens (Stål)) form a model system for dissection of the mechanism of interaction between insect pest and crop. In this review, we focus on the genomics of BPH-rice interaction. On the side of rice, a number of BPH-resistance genes have been identified genetically. Thirteen of these genes have been cloned which shed a light on the molecular basis of the interaction. On the aspect of BPH, a lot of salivary proteins have been identified using transcriptome and proteome techniques...

Transgenic rice expressing cry genes from the bacterium Bacillus thuringiensis (Bt rice) is highly resistant to lepidopteran pests. The brown planthopper (BPH, Nilaparvata lugens) is the main non-target sap-sucking insect pest of Bt transgenic rice. The pond wolf spider (PWS, Pardosa pseudoannulata) is one of the most dominant predators of BPH in rice fields. Consequently, the safety evaluation of Bt rice on BPH and PWS should be conducted before commercialization. In the current study, two experiments were performed to assess the potential ecological effects of Bt rice on BPH and PWS: (1) a tritrophic experiment to evaluate the transmission of Cry1Ac, Cry2Aa and Cry1Ca protein in the food chain; and (2) binding assays of Cry1Ac, Cry2Aa and Cry1Ca to midgut brush border membrane proteins from BPH and PWS...

OBJECTIVE: To assess the mid- to long-term placebo effect of medical and instrumental management of male lower urinary tract symptoms (LUTS). This is - generally - a long-term treatment strategy. Therefore, knowledge on the mid- to long-term placebo effect is of considerable interest. The paucity of data on this topic prompted us to investigate this issue in a meta-analysis. METHODS: All randomized controlled trials (RCTs) with the indication BPH/LUTS containing a placebo- or sham treatment arm and with a follow-up of 12 months were eligible...

OBJECTIVE: to evaluate gene expression of Collagen, Matrix Metalloproteinases (MMP) and Inhibitors, Cholinergic Muscarinic Receptors (CHRM), Angiogenic and Nerve Growth Factors (NGF) in the bladder of patients with Bladder Outlet Obstruction due to Benign Prostatic Hyperplasia METHODS: We analyzed bladder specimens from 43 patients with obstructive BPH undergoing TURP as compared to 10 age-matched controls with IPSS<8 and prostate <30g. A bladder biopsy was performed for relative gene expression analysis with qRT-PCR of Collagens I and III, MMPs 1,2,9; Tissue Inhibitors of Metalloproteinases (TIMP) 1,2 and RECK; CHRM2 and -3; VEGF, CD105; NGF and NGF receptor...

PURPOSE: It is hypothesized that intraarterial administration of verapamil is a safe and effective way to reverse the flow in intraprostatic anastomoses to extraprostatic arteries without compromising treatment outcomes in prostatic artery embolization (PAE) for benign prostatic hypertrophy (BPH). MATERIALS AND METHODS: A prospective study of 62 prostate sides in 31 consecutive patients (median age, 66 y; range, 60-71 y) with symptomatic BPH was undertaken. Median prostate volume was 72...

The incidence of benign prostatic hyperplasia (BPH) is gradually on the increase. While conventional drugs such as the α1-adrenergic receptor antagonists and 5α-reductase inhibitors have been found to be useful in the treatment of BPH, the adverse side effects associated with their usage, have led to increased search for alternative means of managing this disease. Furthermore, although surgery has also been suggested to be a sure method, the cost and risks associated with it excludes it as a routine treatment...

INTRODUCTION: Transurethral resection of the prostate (TURP) is the gold standard for surgical treatment of benign prostatic hyperplasia (BPH), but it has complications such as bleeding and transurethral resection syndrome. The treatment results of TURP performed by non-Japanese board-certified urologists were examined, and the results were analyzed according to the resection volume to determine how much resection volume was suitable for non-Japanese board-certified urologists. MATERIALS AND METHODS: A total of 72 cases that underwent TURP for BPH at our hospital were examined...

Ten normal prostates, 22 benign prostatic hyperplasia (BPH) and 29 prostate cancer (PC) were morphometrically analyzed with regard to mean nuclear area (MNA), mean nuclear perimeter (MNP), mean nuclear diameter (MND), coefficient of variation of the nuclear area (NACV), mean nuclear diameter maximum (MDx), mean nuclear diameter minimum (MDm), mean nuclear form ellipse (MNFe) and form factor (FF). The relationship between nuclear morphometric parameters and histological type, Gleason score, methods of sample collection, presence of metastases and survival time of canine PC were also investigated...

Introduction: Benign prostatic hyperplasia (BPH) is considered as a major cause of lower urinary tract symptoms (LUTS) in older men and its most common sign is nocturia. Objectives: This study aimed to determine the effect of the seeds of Peganum harmala compared with tamsulosin on alleviating urinary symptoms in patients with BPH. Patients and Methods: In this single blind clinical trial study, 90 patients diagnosed with BPH and LUTS, based on international prostate standard survey (IPSS) were divided into three groups...

The levels of core fucosylation and α2,3-linked sialic acid in serum Prostate Specific Antigen (PSA), using the lectins Pholiota squarrosa lectin (PhoSL) and Sambucus nigra agglutinin (SNA), can discriminate between Benign Prostatic Hyperplasia (BPH) and indolent prostate cancer (PCa) from aggressive PCa. In the present work we evaluated whether these glycosylation determinants could also be altered in urinary PSA obtained after digital rectal examination (DRE) and could also be useful for diagnosis determinations...

Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms (LUTS) in older men. In this regard, recent studies have attempted to define the relationships between prostatic fibrosis, LUTS, and increased expression of transforming growth factor β1 (TGF β1) in BHP. Therapeutic approaches for BPH such as 5-α-reductase inhibitors and alpha-adrenergic blocking agents increase TGF β1 expression in the prostatic tissue. Here, we investigated the effects of the 5-α-reductase inhibitor-finasteride-on rat ventral prostate tissue, especially with regard to the tissue distribution and gene expression of fibrillar collagens...

BACKGROUND: Primary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare malignancy. We found only 8 cases of MALT lymphoma in literature. CASE PRESENTATION: We report here another case of primary prostatic MALT lymphoma which is presented by hematuria and diagnosed primarily as BPH. Immunohistochemistry studies demonstrate the diagnosis and MALT lymphoma. Six months after starting the treatment the patient was alive and well. CONCLUSIONS: Prostatic MALTomas are mainly presented with urinary obstruction or hematuria and have an indolent growth with a good prognosis...

Convective radiofrequency (RF) water vapor thermal therapy is a minimally invasive office or outpatient procedure for the treatment of bothersome moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH). It provides an option for patients seeking rapid and durable relief of urinary symptoms, improved quality of life, and preservation of sexual function as an alternative to long-term use of drugs and avoidance of the potential side effects of pharmaceuticals or invasive BPH surgery...

Chronic inflammation is associated with both benign conditions and cancer. Likewise, inflammatory cells are quite common in benign prostatic hyperplasia (BPH) and prostatic tissue harboring cancer. Triggers that activate inflammatory pathways in the prostate remain a subject of argument and are likely to be multifactorial, some of these being bacterial antigens, different chemical irritations, and metabolic disorders. Acute and chronic inflammation in prostate leads to accumulation of immunocompetent cells, mainly T lymphocytes and macrophages, but also neutrophils, eosinophils, and mast cells, depending on the type of offending agent...

Oxidative stress plays an important role in specific disease pathophysiology and the aging process. In the history of human kind, many herbs were utilized for disease prevention and anti-aging treatment. However, there are few direct evidences provided by modern laboratory technology. The current study was designed to evaluate Ganoderma Lucidum's (GL) ability to reduce the damage from in vivo ischemia/reperfusion (I/R) using a rabbit model of I/R that has been effectively utilized to prove the effects of drugs and supplements to reduce oxidative stress...
