For the first time, a novel green method using Zein biopolymeric nanoparticles as a green dispersive solid-phase extractor is reported for the separation and preconcentration of trace amount of nitrite (NO2(-)) ions in ppb levels. The Zein protein is a biodegradable hydrophobic plant protein that is obtained from corn and is composed of a number of hydrophobic amino acids. Zein bionanoparticles were synthesized in an anti-solvent process and used as a new biosorbent in the extraction technique. In the proposed technique, by using a standard method at first, a mixture of 1-naphthylamine and sulphanilic acid as selective regents was added to the samples, and in the presence of the nitrite ion, a red azo product was formed...

BACKGROUND: Matrix metalloproteinases (MMPs), particularly gelatinase A (MMP-2) and gelatinase B (MMP-9), as well as their tissue inhibitors (TIMP-1 and TIMP-2), are involved in the development of skeletal muscle tissue, in the repair process after muscle injury and in the adaptive modifications induced by physical exercise in skeletal muscle. This paper aims at reviewing results from human studies that investigated the role of gelatinases and their inhibitors in skeletal muscle response to acute physical exercise or training...

Background: Terrorism-related deaths are at an all-time high as there were 32,685 and 29,376 terrorism-related deaths in 2014 and 2015, respectively. Terrorism is defined as the use of violence and intimidation in the pursuit of political aims. Terrorism is detrimental for mental health, premature mortality, and economic losses and undermines the central tenets of public health to improve the health and well-being of populations. Despite the impact terrorism has on avoidable morbidity and mortality, population health research largely overlooks social determinants of terrorism and risk factors that contribute to terrorist activities...

BACKGROUND: It is essential to determine the cut-off value of serum anti-Mullerian hormone (AMH) to predict the hyper response in assisted reproductive technology (ART). There are few studies mentioning the cut-off value for the hyper response in infertile women but not specifically for polycystic ovary syndrome (PCOS) and non-PCOS groups. With this in background, this study was conducted. AIM: To determine the cut-off value of serum AMH to predict the hyper response in women with PCOS and non-PCOS undergoing a controlled ovarian stimulation (COS) in ART...

INTRODUCTION: Urine antimicrobial activity is a seldom analysed laboratory test which greatly impacts the quantification of urine specimens. Presence of antimicrobial activity in the urine reduces the bacterial load in these specimens. Hence, the chances of erroneously reporting insignificant bacteriuria can be reduced on analysis of the antimicrobial activity in urine. AIM: The aim of the study was to measure the antimicrobial activity of urine samples obtained from patients in a tertiary care hospital...

The antibody against peptidylarginine deiminase (PAD) 4 is a biomarker that might be helpful in the diagnosis of rheumatoid arthritis (RA). We aim to estimate the diagnostic value of anti-PAD4 antibody for RA by meta-analysis. We searched PubMed, Embase, the Cochrane Library, Web of Science, and Scopus for studies published in any languages in March 1, 2017 that evaluated the diagnostic accuracy of the anti-PAD4 antibody for the diagnosis of RA. The articles that detected the anti-PAD4 antibody by enzyme-linked immunosorbent assay (ELISA) and used healthy donors or patients without arthritis or arthralgia as controls were included for meta-analysis...

ETHNOPHARMACOLOGICAL RELEVANCE: Forsythiae Fructus (called Lianqiao in Chinese), the fruit of Forsythia suspensa (Thunb.) Vahl, is utilized as a common traditional medicine in China, Japan and Korea. It is traditionally used to treat pyrexia, inflammation, gonorrhea, carbuncle and erysipelas. Depending on the different harvest time, Forsythiae Fructus can be classified into two forms, namely Qingqiao and Laoqiao. The greenish fruits that start to ripen are collected as Qingqiao, while the yellow fruits that are fully ripe are collected as Laoqiao...

OBJECTIVES: Long non-coding RNAs (lncRNAs) are a group of non-protein-coding RNAs that are greater than 200 nucleotides in length. Increasing evidence indicates that lncRNAs, which may serve as either oncogenes or tumour suppressor genes, play a vital role in the pathophysiology of human diseases, especially in tumourigenesis and progression. Deregulation of lncRNAs impacts different cellular processes, such as proliferation, dedifferentiation, migration, invasion and anti-apoptosis. The aim of this review was to explore the molecular mechanism and clinical significance of long non-coding RNA-activated by transforming growth factor β (lncRNA-ATB) in various types of cancers...

BACKGROUND: In anti-NMDA receptor (NMDAR) encephalitis, antibody-mediated dysfunction of NMDARs causes severe neuropsychiatric symptoms, including psychosis, memory deficits, and movement disorders. However, it remains elusive how antibody-mediated NMDAR dysfunction leads to these symptoms, and whether the symptoms arise from impairment in specific brain regions and the interactions between impaired regions. METHODS: In this observational study, we recruited 43 patients with anti-NMDAR encephalitis from a tertiary university hospital and 43 age-matched and sex-matched healthy controls without a history of neurological or psychiatric disorders, who were recruited from the general population of Berlin...

Since Jenner, vaccines and vaccinations have stirred a hot, highly polarized debate, leading to contrasting positions and feelings, ranging from acritical enthusiasm to blind denial. On the one hand, we find anti-vaccination movements which divulge and disseminate misleading information, myths, prejudices, and even frauds, with the main aim of denying that vaccination practices represent a major public health measure, being effective in controlling infectious diseases and safeguarding the wellbeing of entire communities...

Despite an improved understanding of cancer molecular biology, immune landscapes, and advancements in cytotoxic, biologic, and immunologic anti-cancer therapeutics, cancer remains a leading cause of death worldwide. More than 8.2 million deaths were attributed to cancer in 2012, and it is anticipated that cancer incidence will continue to rise, with 19.3 million cases expected by 2025. The development and investigation of new diagnostic modalities and innovative therapeutic tools is critical for reducing the global cancer burden...

: While the overall incidence of HIV infections in the United States (US) has decreased in recent years, certain populations remain particularly vulnerable, including racial/ethnic minorities, adolescents/young adults, and people in the southern US [1]. The Centers for Disease Control and Prevention (CDC) stated strategy to combat new infections includes a combination of "cost-effective, scalable interventions based on current science" [2]. In July 2012, the US Food and Drug Administration (FDA) approved daily oral combination tenofovir/emtricitabine ("Truvada") for pre-exposure prophylaxis (PrEP) in at-risk uninfected adults, with subsequent endorsement as blanket policy by the CDC in May 2014 [3]...

Resveratrol is a natural dietary phenolic compound which is extensively present in many edible fruits, including grape, berries, pomegranates, and peanuts. Reseveratrol has a broad spectrum of biological activities including anti-aging, chemopreventive, anti-carcinogenic, anti-inflammatory and antioxidant effects and thus it is effective in related diseases. Particularly, the positive effects of resveratrol in neuropsychological diseases have been proven in in-vitro and in-vivo studies. Some clinical trials have reported that resveratrol possesses preventive and therapeutic effects in cognitive disorders...
