BACKGROUND: To our knowledge, there are no experimental studies that have addressed the effects of starvation on the maintenance of telomere length. Two epidemiologic studies that have addressed this topic gave controversial results. OBJECTIVE: We characterized leukocyte telomere length (LTL) in a Chuvash population that was comprised of survivors of the mass famine of 1922-1923 and in these survivors' descendants. DESIGN: The tested cohort consisted of native Chuvash men (n = 687) and women (n = 647) who were born between 1909 and 1980 and who resided in small villages in the Chuvash Republic of the Russian Federation...

The peptide aptamer DUP-1 targets prostate-specific membrane antigen (PSMA)-negative cells, while the RNA aptamer A10-3.2 targets PSMA-positive prostate cancer cells. Moreover, the tumor-suppressor gene phosphatase and tensin homolog (PTEN) and the chemotherapeutic agent doxorubicin (DOX) effectively inhibit prostate cancer, and a recombinant adenovirus (Ad5) mediates high gene transfer efficiency. Here, we design a dual-aptamer modified tumor targeting gene and DOX delivery system mediated by recombinant adenovirus (A10-3...

Polyhydroxyalkanoates (PHAs) are biodegradable polymers that can substitute for petroleum-based plastics in a variety of applications. One avenue to commercial PHA production involves coupling waste-based synthesis with the use of mixed microbial consortia (MMC). In this regard, production requires maximizing the enrichment of a MMC capable of feast-famine PHA synthesis, with the metabolic response induced through imposition of aerobic-dynamic feeding (ADF) conditions. However, the concept of PHA production in complex matrices remains unrefined; process operational improvements are needed, along with an enhanced understanding of the MMC...

PURPOSE: The Great Chinese Famine afflicted almost all Chinese people between 1959 and 1961. No study has explicitly assessed the association between an exposure to Chinese Famine and risk of overall breast cancer and tumor subtype. We evaluated the unique historical environmental influences of famine exposure on breast cancer subtypes. METHODS: 16,469 Chinese women who were diagnosed with invasive breast cancer in the Fudan University Shanghai Cancer Center (FUSCC) from 1999 to 2014 were analyzed...

The "thrifty gene hypothesis" suggests genetic susceptibility to obesity arises because of positive selection for alleles that favored fat deposition and survival during famines. We used public domain data to locate signatures of positive selection based on derived allele frequency, genetic diversity, long haplotypes, and differences between populations at SNPs identified in genome-wide association studies (GWASs) for BMI. We used SNPs near the lactase (LCT), SLC24A5, and SLC45A2 genes as positive controls and 120 randomly selected SNPs as negative controls...

Currently, the feast and famine (FF) regime is the most widely applied strategy to select for polyhydroxyalkanoate (PHA) accumulating organisms in PHA production systems with mixed microbial cultures. As an alternative to the FF regime, this work studied the possibility of utilizing a permanent feast regime as a new operational strategy to select for PHA accumulating photosynthetic mixed cultures (PMCs). The PMC was selected in an illuminated environment and acetate was constantly present in the mixed liquor to guarantee a feast regime...

Environmental factors such as temperature strongly impact microbial communities. In the current context of global warming, it is therefore crucial to understand the effects of these factors on human, animal, or plant pathogens. Here, we used a common-garden experiment to analyze the thermal responses of three life-history traits (latent period, lesion growth, spore number) in isolates of the potato late blight pathogen Phytophthora infestans from different climatic zones. We also used a fitness index (FI) aggregating these traits into a single parameter...

World War I irrevocably changed the face of the world, including Croatia and its capital Zagreb. While between 1880 and 1910 Zagreb became a modern European city, World War I (1914-1918) was marked by new municipal regulations that overturned the everyday life of the city. Social conditions reached catastrophic proportions, especially in the later years of the war. Soldiers and refugees swarmed the city, and famine and the Spanish flu epidemic hit it hard. In such harsh social and economic circumstances Milan Rojc, head of the Theology and Education Department and three doctors from the Sisters of Mercy Hospital, namely, Theodor Wikerhauser, Miroslav Čačković pl...

BACKGROUND: Evidence shows that exposure to poor conditions in early life is associated with an increased risk of chronic diseases in adults. OBJECTIVE: We investigated whether exposure to the Chinese famine (1959-1961) in the fetal stage or in childhood (0-9 y) was associated with type 2 diabetes (T2D) and hyperglycemia in adulthood. METHODS: We included 7801 subjects aged 56.4 ± 3.3 y from the Dongfeng-Tongji cohort. Subjects were classified into late-, middle-, and early-childhood-exposed, fetal-exposed, and unexposed groups...

This work aims to investigate the stability of aerobic granular sludge in the long term, focusing on the clogging of the granular sludge porosity exerted by the extracellular polymeric substances (EPSs). The effects of different cycle lengths (short and long-term cycle) on the granular sludge stability were investigated. Results obtained outlined that during the short duration cycle, the formation and breakage of the aerobic granules were continuously observed. During this period, the excess of EPS production contributed to the clogging of the granules porosity, causing their breakage in the long run...

BACKGROUND: Since 2009, millions of people have been forced to live under food shortage by the continuous drought in Southwestern China. The market was the primary source of aid grains, and fears that the market will be unable to provide sufficient food make safeguarding food security in the face of climate change crucial. Traditional adaptive strategies of pre-market indigenous people are a potential source of innovation. We studied three questions among the Naxi people: 1) What edible plants did they consume during droughts? 2) How did they produce enough food? 3) How did they consume these plants? This study investigates and documents traditional Naxi food knowledge to safeguard food security during drought and facilitate Chinese policy decisions...

OBJECTIVES: Famine exposure in early life has been reported to be associated with higher risk of hypertension prevalence in adults. The aim of the present study was to investigate the association of exposure to the Chinese famine during early life with the risk of hypertension prevalence in adults. METHODS: There were 8742 participants born between 1952 and 1964 derived from the Dongfeng-Tongji cohort included in the present study. Participants were classified as nonexposed group, fetal exposed group, early-childhood exposed group, mid-childhood exposed group, and late-childhood exposed group, respectively...

OBJECTIVES: Early-life adversity has been shown to be associated with cardiovascular disease and mortality in later life, but little is known about the mechanisms that underlie this association. Prenatal undernutrition, a severe early-life stressor, is associated with double the risk of coronary heart disease and increased blood pressure responses to psychological stress. In the present study, we tested the hypothesis that prenatal undernutrition induces alterations in the autonomic nervous system, which may increase the risk of developing heart disease...

This paper examines the extent to which pre-puberty nutritional conditions in one generation affect productivity-related outcomes in later generations. Recent findings from the biological literature suggest that the so-called slow growth period around age 9 is a sensitive period for male germ cell development. We build on this evidence and investigate whether undernutrition at those ages transmits to children and grandchildren. Our findings indicate that third generation males (females) tend to have higher mental health scores if their paternal grandfather (maternal grandmother) was exposed to a famine during the slow growth period...

A series of pilot-scale studies were performed to compare conventional high-rate activated sludge systems (HRAS) (continuous stirred tank reactor (CSTR) and plug flow (PF) reactor configurations) with high-rate contact-stabilization (CS) technology in terms of carbon recovery potential from chemically enhanced primary treatment effluent at a municipal wastewater treatment plant. This study showed that carbon redirection and recovery could be achieved at short solids retention time (SRT). However, bioflocculation became a limiting factor in the conventional HRAS configurations (total SRT ≤ 1...

BACKGROUND: Nutritional deprivation during growth and development may contribute to colorectal cancer (CRC) risk in later life. METHODS: We studied 7906 women who were aged 0-21 years during the 1944-45 Dutch famine, who enrolled in the Prospect-EPIC study between 1993 and 1997. We used Cox proportional hazard analyses to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for colorectal (proximal, distal and rectal) cancer risk across self-reported famine exposure and exposure-age categories, while adjusting for potential confounders...

The Sakarya River Basin (SRB) contains one of the most important agricultural areas for Turkey. Here, we use a network of 18 tree-ring chronologies and present a reconstruction of the mean June-July Kocasu River discharge, one of the main channels in the SRB, during the period 1803-2002 CE, and place the short period of instrumental flows (since 1953 CE) into historical context. Over the past two centuries, we found 33 dry and 28 wet events and observed the longest wet period between the years 1880 and 1920...

We report evidence of long-term adverse health impacts of fetal malnutrition exposure of middle-aged survivors of the 1959-1961 China Famine using data from the China Health and Retirement Longitudinal Study. We find that fetal exposure to malnutrition has large and long-lasting impacts on both physical health and cognitive abilities, including the risks of suffering a stroke, physical disabilities in speech, walking and vision, and measures of mental acuity even half a century after the tragic event. Our findings imply that policies and programs that improve the nutritional status of pregnant women yield benefits on the health of a fetus that extend through the life cycle in the form of reduced physical and mental impairment...

The major components of human diet both past and present may be estimated by measuring the carbon and nitrogen isotope ratios (δ13C and δ15N) of the collagenous proteins in bone and tooth dentine. However, the results from these two tissues differ substantially: bone collagen records a multi-year average whilst primary dentine records and retains time-bound isotope ratios deriving from the period of tooth development. Recent studies harnessing a sub-annual temporal sampling resolution have shed new light on the individual dietary histories of our ancestors by identifying unexpected radical short-term dietary changes, the duration of breastfeeding and migration where dietary change occurs, and by raising questions regarding factors other than diet that may impact on δ13C and δ15N values...
