Leaf area index (LAI) is one of the key biophysical parameters in crop structure. The accurate quantitative estimation of crop LAI is essential to verify crop growth and health. The PROSAIL radiative transfer model (RTM) is one of the most established methods for estimating crop LAI. In this study, a look-up table (LUT) based on the PROSAIL RTM was first used to estimate winter wheat LAI from GF-1 data, which accounted for some available prior knowledge relating to the distribution of winter wheat characteristics...

Isomeric double-decker silsesquioxane-functionalized dinuclear alkynylplatinum(ii) terpyridine complexes demonstrate self-association behaviours via the stabilisation of hydrophobic, PtPt and/or π-π stacking interactions. These supramolecular architectures and molecular packings are found to be closely related to the isomeric configurations of the complexes and have been investigated using various spectroscopic studies.

BACKGROUND: Benign prostatic hyperplasia (BPH) is a common urologic disease in older men. Prostatic inflammation research has focused on the magnitude of inflammation; its location has received little attention. We investigated whether the anatomic location of prostatic inflammation is related to the severity of lower urinary tract symptoms (LUTS), measured subjectively and objectively. METHODS: We retrospectively analyzed hematoxylin+eosin-stained tissue specimens from 179 BPH patients who underwent transurethral resection of the prostate (TURP) or holmium laser enucleation of the prostate (HoLEP)...

INTRODUCTION: Lower urinary tract symptoms (LUTS) from bladder outlet obstruction from benign prostatic hyperplasia (BPH) occur in a large percentage of urologic patients. Treatment of this condition with medical and surgical therapy provides symptom relief but has serious adverse effects and causes sexual dysfunction. New technologies to treat BPH-associated LUTS aim to effectively treat urinary symptoms and minimize side effects and sexual dysfunction. AIM: To review the efficacy of new and emerging therapies for treatment of LUTS from BPH...

INTRODUCTION: Asymptomatic post-renal transplant reflux is common but only 5-10% patients are diagnosed with vesico-ureteral reflux in the setting of post-transplant febrile urinary tract infections, requiring redo ureteroneocystostomy (redo-UNC). Here we report the renal function outcomes of 37 such patients, stratified by lower urinary tract (LUT) status. OBJECTIVE: We hypothesized that those with pre-transplant LUT dysfunction would have lower glomerular filtration rate (GFR) on follow-up...

OBJECTIVE: Intermittent explosive disorder (IED) is defined as the failure to resist aggressive impulses resulting in repeated acts of verbal and/or physical aggression. Although it is frequently encountered in clinical psychiatric practice, there is a paucity of data concerning IED in the scientific literature both internationally and in Turkey. The aim of this study was to evaluate the prevalence of IED and associated sociodemographic and clinical features in a clinical setting. METHODS: A total of 406 patients who were referred to our psychiatry outpatient clinic for the first time in a six-month period were included in the study...

Although the exact nature of the association between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) is still not completely understood, findings that men with metabolic alterations experience faster-developing LUTS or are more frequently candidates for benign prostatic enlargement (BPE) surgery support the hypothesis that metabolic and pathological derangements characterizing MetS can promote the development and progression of BPE and LUTS. The strong evidence that MetS is associated with larger prostate size supports a role for metabolic derangements in the development and progression of BPE...

PURPOSE OF REVIEW: Guidelines have been developed to assist physicians in the diagnosis and management of patients with lower urinary tract symptoms. These guidelines vary in the level of evidence used and the strength of their recommendations. With variations in guidelines, multiple variations in clinical practice may also been seen. RECENT FINDINGS: Although examinations of physician compliance with benign prostatic hyperplasia (BPH) guidelines date back to the 1980s, researchers have become more interested in closer examination of guideline compliance...

We present an all-fiber intracavity photothermal (IC-PT) spectroscopic gas sensor with a hollow-core photonic bandgap fiber (HC-PBF) gas cell. The gas cell is placed inside a fiber-ring laser cavity to achieve higher laser light intensity in the hollow core and hence higher PT modulation signal. An experiment with a 0.62-m-long HC-PBF gas cell demonstrated a noise equivalent concentration of 176 ppb acetylene. Theoretical modeling shows that the IC-PT sensor has the potential of achieving sub-ppb (parts-per-billion) acetylene detection sensitivity...

Background: According to their guidelines, Dutch general practitioners (GPs) refer men with prostate-specific antigen (PSA) level ≥3.0 ng/mL to the urologist for risk-based patient selection for prostate biopsy using the Rotterdam Prostate Cancer Risk Calculator (RPCRC). Use of the RPCRC in primary care could optimize the diagnostic pathway even further by reducing unnecessary referrals. To investigate this, we calculated the risk and assessed the rate of men referred to the urologist with PSA level ≥3...

In this paper, an analytical method to estimate the complex dielectric constant of liquids is presented. The method is based on the measurement of the transmission coefficient in an embedded microstrip line loaded with a complementary split ring resonator (CSRR), which is etched in the ground plane. From this response, the dielectric constant and loss tangent of the liquid under test (LUT) can be extracted, provided that the CSRR is surrounded by such LUT, and the liquid level extends beyond the region where the electromagnetic fields generated by the CSRR are present...
