Jonas Nilsson, Georg Holgersson, Tobias Carlsson, Roger Henriksson, Stefan Bergström, Michael Bergqvist
The focus of the present review is to investigate whether there is a variation in the incidence rates between male and female patients with high-grade primary brain tumors and if there are altered incidence rates associated with the time at which they were diagnosed. Previous studies identified in internationally peer-reviewed journals were identified using a systematic search of the PubMed database. Due to the difficulties in data interpretation, studies that exclusively included patient data classified prior to the 2nd edition of the World Health Organization histological classification system of brain tumors were excluded...

Ellagic acid is a phenolic compound naturally present in nuts and berries. Several studies have demonstrated that this bioactive compound has antioxidant, chemopreventive and antiviral activity. Annona muricata is a type of fruit tree with a long history of traditional use. A number of properties have been attributed to different parts of the plant, including anticancer and antioxidant activities. In the current study, a complex based on ellagic acid, Annona Muricata and antioxidant factors (an ellagic acid complex) was administered to a group of human papilloma virus (HPV) infected women with and without cervical lesions, for 12 months...

Lei Wei, Nandini Bhattacharya, H Paul Urbach
We describe a method to control the directional scattering of a high-index dielectric nanosphere, which utilizes the unique focusing properties of an azimuthally polarized phase vortex and a radially polarized beam to independently excite inside the nanosphere a spinning magnetic dipole and a linearly polarized electric dipole mode normal to the magnetic dipole. We show that by simply adjusting the phase and amplitude of the field on the exit pupil of the optical system, the scattering of the nanosphere can be tuned to any direction within a plane, and the method works over a broad wavelength range...

The Letter proposes a new layout of a passively mode-locked fiber laser based on a nonlinear amplifying loop mirror (NALM) with two stretches of active fiber and two independently controlled pump modules. In contrast with conventional NALM configurations using a single piece of active fiber that yields virtually constant peak power, the proposed novel laser features larger than a factor of 2 adjustment range of peak power of generated pulses. The proposed layout also provides independent adjustment of duration and peak power of generated pulses as well as power-independent control of generated pulse spectral width impossible in NALM lasers with a single piece of active fiber...

We investigated whether single nucleotide polymorphisms (SNPs) in the nuclear assembly factor 1 (NAF1) and TNFAIP3-interacting protein 1 (TNIP1) gene were associated with susceptibility to esophageal cancer in a Chinese Han population. Five SNPs were genotyped and their relationship with esophageal cancer risk was analyzed in a sample of 386 esophageal cancer patients and 495 unrelated healthy controls recruited from the First Affiliated Hospital of Xi'an Jiaotong University. Patients with the AG genotype of rs2320615 were at lower risk of developing esophageal cancer than those with the GG genotype (adjusted odds ratio [OR] = 0...

The measurement of progesterone (P4) and estradiol (E2) is essential for monitoring reproductive cycles and can aid in diagnosing the cause of poor reproductive performance in dairy cattle. Readily available, reproducible, accurate, non-radioactive assays are needed for the assessment of P4 and E2 in bovine serum. The gold standard for hormone assessment, radioimmunoassay (RIA), was compared with enzyme-linked immunoassay (EIA). Serum collected from various points in the estrous cycle was extracted with radiolabeled P4 (ie, (3)H-P4; HE) and without (3)H-P4 (CE) before being used in the assay...

We hypothesized that tumor necrosis factor receptor-1 (TNFR1) levels are associated with long-term trajectories of functional status independently of vascular risk factors and stroke and myocardial infarction (MI) occurring during follow-up. In the Northern Manhattan Study, stroke-free individuals in northern Manhattan aged >40 years had annual assessments with the Barthel index (BI) for a median of 13 years. Baseline demographics, risk factors, and laboratory studies included TNFR1 (n = 1,863). Generalized estimating equation models estimated standardized associations between TNFR1 and 1) baseline functional status and 2) change in function over time, adjusting for demographics, vascular risk factors, social variables, cognition, and depression, and stroke and MI occurring during follow-up...
