Sample preparation, typically by in-solution or in-gel approaches, has a strong influence on the accuracy and robustness of quantitative proteomics workflows. The major benefit of in-gel procedures is their compatibility with detergents (such as SDS) for protein solubilization. However, SDS-PAGE is a time-consuming approach. Tube-gel (TG) preparation circumvents this drawback as it involves directly trapping the sample in a polyacrylamide-gel matrix without electrophoresis. We report here the first global label-free quantitative comparison between TG, stacking gel (SG), and basic liquid digestion (LD)...

OBJECTIVE: To determine whether race/ethnicity and socioeconomic status are associated with amyotrophic lateral sclerosis (ALS) mortality in the United States. METHODS: The National Longitudinal Mortality Study (NLMS), a United States-representative, multistage sample, collected race/ethnicity and socioeconomic data prospectively. Mortality information was obtained by matching NLMS records to the National Death Index (1979-2011). More than 2 million persons (n = 1,145,368 women, n = 1,011,172 men) were included, with 33,024,881 person-years of follow-up (1,299 ALS deaths , response rate 96%)...

INTRODUCTION: In 1979, the Copenhagen group around Dr. Skakkebaek introduced contralateral biopsy in patients with testicular germ cell tumour (GCT) as a means of early diagnosing a contralateral testicular tumour (Berthelsen et al. in Br Med J 2(6186):363-364, 1). Although the rationale of contralateral biopsies is based on much of scientific evidence, no issue regarding the management of GCTs has been more controversial than the issue of contralateral biopsies (Heidenreich in BJU Int 104(9 Pt B):1346-1350, 2; Grigor and Rorth in Eur Urol 23(1):129-135, 3)...

Recently, low serum uric acid (SUA) levels and high SUA levels, have emerged as risk factors for cardiovascular disease, as well as for the incidence of acute kidney injury and chronic kidney disease (CKD). However, the effect of low SUA on the progression of CKD remains unclear. To evaluate the association between SUA and renal prognosis in patients with immunoglobulin A nephropathy (IgAN), one of the most common causes of CKD, we retrospectively followed 1218 patients who were diagnosed with primary IgAN by kidney biopsy between October 1979 and December 2010...

BACKGROUND: Southern China is an endemic area for primary liver cancer (PLC), but it is unclear if rates have changed in recent decades. We evaluated PLC incidence and estimated the effects of age, period of diagnosis, and birth cohort in Sihui City, Guangdong Province, China. METHODS: Age-standardized rates (ASRs) of PLC were examined for both males and females from 1987 to 2011. Joinpoint regression analysis was conducted to estimate the annual percent changes in PLC incidence...

Background The goal of screening mammography is to detect small malignant tumors before they grow large enough to cause symptoms. Effective screening should therefore lead to the detection of a greater number of small tumors, followed by fewer large tumors over time. Methods We used data from the Surveillance, Epidemiology, and End Results (SEER) program, 1975 through 2012, to calculate the tumor-size distribution and size-specific incidence of breast cancer among women 40 years of age or older. We then calculated the size-specific cancer case fatality rate for two time periods: a baseline period before the implementation of widespread screening mammography (1975 through 1979) and a period encompassing the most recent years for which 10 years of follow-up data were available (2000 through 2002)...

Chronic lower respiratory diseases (CLRDs) are a major cause of morbidity and mortality worldwide. The objectives of this study were to estimate the trends in CLRD mortality in Italy, and the specific contributions of age, time period and birth cohort in driving these trends. Population and cause-of-death data in Italy between 1979 and 2010 were collected from the World Health Organization website. Age-specific mortality rates for CLRDs, and effects for age, time period and birth cohort on mortality trends were estimated using age-period-cohort models...

BACKGROUND: Cancer incidence and mortality projections are important for understanding the evolving landscape for cancer risk factors as well as anticipating future burden on the health service. METHODS: We used an age-period-cohort model with natural cubic splines to estimate cancer cases and deaths from 2015 to 2035 based on 1979-2014 UK data. This was converted to rates using ONS population projections. Modified data sets were generated for breast and prostate cancers...

Smallpox is considered among the most devastating of human diseases. Its spread in populations, initiated for thousands of years following a probable transmission from an animal host, was concomitant with movements of people across regions and continents, trade and wars. Literature permitted to retrace the occurrence of epidemics from ancient times to recent human history, smallpox having affected all levels of past society including famous monarchs. The disease was officially declared eradicated in 1979 following intensive vaccination campaigns...

BACKGROUND: Toxoplasma gondii is an obligate intracellular protozoan infecting up to one-third of the world's population, constituting a life threat if transmitted from mother to child during pregnancy. In Portugal, there is a lack of knowledge of the current epidemiological situation, as the unique toxoplasmosis National Serological Survey was performed in 1979/1980. METHODS: We studied the seroprevalence trends in the Portuguese general population over the past 3 decades, by assessing chronological spread cross-sectional studies, with special focus on women of childbearing age, by age group, region and gender...

: Background Agricultural production has expanded dramatically throughout Brazil. Previous research in the Serrana Region found that from 1979 to 1998, agricultural workers experienced high mortality rates from certain cancers compared to non-agricultural workers [Meyer et al. (2003): Environ Res 93:264-271]. METHODS: New data were obtained for 1999-2013 and Mortality Odds Ratios (MORs) were utilized to compare cancer and other mortality between male agricultural workers in the Serrana Region and non-agricultural workers in the Serrana Region, Rio de Janeiro, and Porto Alegre, and to compare mortality odds to previous decades...

Acromegaly is a hormonal disorder that arises when the pituitary gland secretes excess growth hormone (GH), which in turn stimulates a concomitant increase in serum insulin-like growth factor 1 (IGF-1) levels. Gastroenteropancreatic neuroendocrine tumours (GEP-NET) constitute a heterogeneous group of tumours that can secrete serotonin and a variety of peptide hormones that may cause characteristic symptoms known as carcinoid syndrome, or other symptoms and hormonal hypersecretion syndromes depending on the tumour's site of origin...

The present study on insight is based on an integration of Kaplan and Simon's (1990) information processing theory of insight, a cognitive style theory, and achievement motivation theory. The style theory is the Assimilator (rule oriented, familiarity seeking)-Explorer (novelty seeking, explorative) styles (Kaufmann, 1979). Our hypothesis is that the effectiveness of 2 types of search constraints (prior experience and solution hints) for solving insight problems is moderated by both cognitive style and achievement needs, and depending on optimal levels of achievement motivation for different task conditions...

: Anthrax is a zoonotic disease that occurs naturally in wild and domestic animals but has been used by both state-sponsored programs and terrorists as a biological weapon. A Soviet industrial production facility in Sverdlovsk, USSR, proved deficient in 1979 when a plume of spores was accidentally released and resulted in one of the largest known human anthrax outbreaks. In order to understand this outbreak and others, we generated a Bacillus anthracis population genetic database based upon whole-genome analysis to identify all single-nucleotide polymorphisms (SNPs) across a reference genome...

Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary databases. Such data sources bring challenges as well as advantages, however...

A new species of Falsopodabrus Pic, 1927 is described, Falsopodabrus tridentatus Yang, sp. n. (Yunnan, China). Geometric morphometric analyses based on the shapes of pronotum and hind wing and comparisons with two sibling species, Falsopodabrus himalaicus Wittmer, 1974 and Falsopodabrus martensi (Wittmer, 1979), support the valid status of the new species, also confirmed by the characters of tarsal claws. In addition to Falsopodabrus himalaicus and Falsopodabrus martensi, Falsopodabrus kostali Švihla, 2004 and Falsopodabrus rolciki Švihla, 2004 are recorded from China for the first time...

BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is a rare and low-grade soft tissue lesion that typically arises from subcutaneous and deep dermal tissue of extremities. The first case was reported in 1979 by Enzinger, and since has become known as a distinct entity. AFH has been increasingly reported in different organ systems, with rare reports of primary intracranial AFH. To date there have been 3 reports of intracranial AFH and one report of metastasis to the brain, most of which were in young adults...
