The objective of this study is to compare cancer risk among different generations of Middle Eastern (ME) immigrants and Non-Hispanic Whites (NHW) in California between 1988 and 2013. We used data from the California Cancer Registry to identify invasive primary incident cancer cases in three population groups: a) first generation ME immigrants, b) second or subsequent generations ME immigrants, and c) NHW. Proportional Incidence Ratio (PIR) was used to compare cancer risk of the 15 selected most common cancers in the 3 population groups taking into consideration time since immigration for first generation ME immigrants...

Indoor human tracking and activity recognition are fundamental yet coherent problems for ambient assistive living. In this paper, we propose a method to address these two critical issues simultaneously. We construct a wireless sensor network (WSN), and the sensor nodes within WSN consist of pyroelectric infrared (PIR) sensor arrays. To capture the tempo-spatial information of the human target, the field of view (FOV) of each PIR sensor is modulated by masks. A modified partial filter algorithm is utilized to decode the location of the human target...

BACKGROUND: Plasmodium cynomolgi, a non-human primate malaria parasite species, has been an important model parasite since its discovery in 1907. Similarities in the biology of P. cynomolgi to the closely related, but less tractable, human malaria parasite P. vivax make it the model parasite of choice for liver biology and vaccine studies pertinent to P. vivax malaria. Molecular and genome-scale studies of P. cynomolgi have relied on the current reference genome sequence, which remains highly fragmented with 1,649 unassigned scaffolds and little representation of the subtelomeres...

BACKGROUND: It is unclear whether a short-term change in circulating androgens is associated with changes in the transcriptome of the peripheral blood mononuclear cells (PBMC). AIMS & METHODS: To explore the effect of hCG-stimulation on the PBMC-transcriptome, 12 boys with a median age (range) of 0.7yrs (0.3, 11.2) who received intramuscular hCG 1500u on 3 consecutive days as part of their investigations underwent transcriptomic array analysis on RNA extracted from peripheral blood mononuclear cells before and after hCG stimulation...

KEY POINTS: An early inflammatory response and oxidative stress are implicated in the signal transduction that alters both hepatic redox status and mitochondrial function after traumatic brain injury (TBI). Peripheral oxidative/inflammatory responses contribute to neuronal dysfunction after TBI Exercise training alters the profile of oxidative-inflammatory status in liver and protects against acute hyperglycaemia and a cerebral inflammatory response after TBI. Approaches such as exercise training, which attenuates neuronal damage after TBI, may have therapeutic potential through modulation of responses by metabolic organs...

In patients colonized with extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E), the preference for carbapenems (CRB) over non-CRB antibiotics for empiric therapy of sepsis is questionable from an ecologic perspective and also how well colonization actually predicts an ESBL-E etiology of infection has been poorly investigated. The purpose of this retrospective observational study was to determine the positive predictive value (PPV) of ESBL-E fecal colonization for ESBL-E etiology of sepsis and the impact of empiric therapy on treatment outcome...

Several infectious disease outbreaks with high mortality in humans have been attributed to viruses that are thought to have evolved from bat viruses. In this study from Luxembourg, the genetic diversity and epidemiology of paramyxoviruses and coronaviruses shed by the bat species Rhinolophus ferrumequinum and Myotis emarginatus was evaluated. Faeces collection (n= 624) was performed longitudinally in a mixed-species colony in 2015 and 2016. In addition, faeces (n= 254) were collected cross-sectionally from six Myotis emarginatus colonies in 2016...

Purpose: To date keratoconus (KC) pathogenesis is undefined; however, the involvement of inflammatory pathways in disease development is becoming apparent. In the present study, we investigated the role of a promoter region polymorphism rs1800629 (-308G>A) in the inflammatory pathway component TNF-α and its effects on the expression of TNF-α and downstream molecules tumor necrosis factor receptor 1 and 2 (TNFR1 and TNFR2), v-rel avian reticuloendotheliosis viral oncogene homolog A (RELA), and interleukin 6 (IL-6) in KC development...

The site of La Quina Amont, located in the Charente region, is one of the most important sites in southwestern France for studying major changes in human behaviors from the Middle Paleolithic (MP) to the Early Upper Paleolithic (EUP). Extensively excavated over the past 50 years, numerous dating studies have been focused on the Upper Paleolithic deposits using radiocarbon on bone collagen and thermoluminescence (TL) on heated flints; however, the Mousterian levels remain undated due to the scarcity of suitable materials...

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and debilitating lung disease with a median survival time of 3-5 years. For now, pirfenidone (PIR) and nintedanib (NTB) are the only drugs that can slow down the disease's progression. In Poland, these drugs, although registered for legal use, had not been reimbursed for IPF patients until the end of the year 2016. Aim of the study was to assess what was common practice in terms of diagnosis and treatment in the period before antifibrotic drugs became available for IPF patients in Poland...

The chronic, destructive autoimmune arthritis in SKG mice, which closely resembles human rheumatoid arthritis, is the result of self-reactive T cells escaping thymic deletion. Since the inhibitory receptor LIR-1 is up-regulated on auto-reactive T cells in human rheumatoid arthritis, the role of its murine ortholog PIR-B was investigated. Peripheral CD4(+) T cells from SKG mice were found to frequently express PIR-B, and this population produces more frequently IL-17 upon in vitro stimulation compared to PIR-B(-) cells...

INTRODUCTION: In high-resource countries, modern treatments for urological diseases have led to significant reductions in mortality and morbidity; however, the benefits of modern treatment have yet to reach the majority of people worldwide. As attention is focused on improving urological care in the global community, policy and implementation research (PIR) offers a platform for effective organization and engagement. METHODS: We have compiled a photo essay to illustrate the fundamental components of PIR...

PIWI-interacting RNA Likes (piR-Ls) were recently reported to regulate functions of their target phospho-Proteins (p-Proteins) in somatic lung cells. However, the mechanism underlying this functionality remains unclear. piR-Ls interact with their targets through direct binding but do not follow base-pairing rules, known to have important roles at levels of transcription, RNA processing and translation for small non-coding RNA (sncRNA). These observations imply a fundamentally different type of sncRNA with behavior that causes a molecular response in their target p-Proteins...

Stomata respond to darkness by closing to prevent excessive water loss during the night. Although the reorganisation of actin filaments during stomatal closure is documented, the underlying mechanisms responsible for dark-induced cytoskeletal arrangement remain largely unknown. We used genetic, physiological and cell biological approaches to show that reorganisation of the actin cytoskeleton is required for dark-induced stomatal closure. The opal5 mutant does not close in response to darkness but exhibits wild-type (WT) behaviour when exposed to abscisic acid (ABA) or CaCl2 ...

AIM: Patients with type 2 diabetes mellitus (DM) often delay the initiation or titration of insulin treatment due to psychological factors. This phenomenon is referred to as psychological insulin resistance (PIR). The insulin treatment appraisal scale (ITAS) is a 20-item instrument for assessing PIR. A previous Chinese version of the ITAS (C-ITAS) was found to be subject to problems arising from its translation. The present study aimed to translate and validate this instrument, which will facilitate research and aid in counselling in a clinical setting...

PURPOSE: Status epilepticus (SE) causes irreversible neurodegeneration if not terminated quickly. Perampanel (PER), a potent AMPA receptor antagonist, has previously been shown to terminate seizures in the lithium-pilocarpine SE model. In the present study, we assessed whether PER would also prevent neuronal damage in this model. METHODS: SE was induced in rats using lithium chloride and pilocarpine. Initiation of SE was defined as continuous seizures that exhibited as rearing accompanied by bilateral forelimb clonus (Racine score 4)...

Piwi-interacting RNAs (piRNAs), a novel class of small non-coding RNA, were first discovered in germline cells and are thought to silence transposons in spermatogenesis. Recently, piRNAs have also been identified in somatic tissues, and aberrant expression of piRNAs in tumor tissues may be implicated in carcinogenesis. However, the function of piR-823 in colorectal cancer (CRC) remains unclear. Here, we first found that piR-823 was significantly up-regulated in CRC tissues compared with its expression in the adjacent tissues...
