OBJECTIVE(S): Colombia has the third largest black population in the Americas after Brazil and the USA. In 2005 mortality rate under 5 in Colombia was 21.5 per 1000, with a reduction of 82% between 2005 and 1955. That rate is not in line with rates for Cuba (6.8), Chile (9.1) or Costa Rica (10.4). Here we aim to provide evidence that a further reduction of child mortality relates to the unspoken racial gap in a pioneering country in family planning and praised in the 2000 WHO report as having the world's fairest health care reform in terms of coverage and financial access...

We aimed at investigating mortality among beryllium-exposed workers, according to solubility of beryllium and beryllium compounds. We conducted an historical cohort study of 16,115 workers employed during 1925-2008 in 15 facilities, including eight entailing exposure to insoluble beryllium and seven entailing exposure to soluble/mixed beryllium compounds, who were followed up for mortality until 2011. Data were analyzed using indirect standardization and Cox regression modeling. Lung cancer standardized mortality ratio (SMR, national reference rates) was 1...

This article examines the transfer of technology from Finnish enterprises to Soviet industry during the USSR's period of technological modernization between 1955 and 1964. It centers on the forestry sector, which was a particular focus of modernization programs and a key area for the transfer of foreign techniques and expertise. The aim of the article is to investigate the role of trips made by Soviet specialists to foreign (primarily Finnish) enterprises in order to illustrate the nontechnological influences that occurred during the transfer of technologies across the cold war border...

BACKGROUND: Many treatments for the common cold exist and are sold over-the-counter. Nevertheless, evidence on the effectiveness and safety of nasal decongestants is limited. OBJECTIVES: To assess the efficacy, and short- and long-term safety, of nasal decongestants used in monotherapy to alleviate symptoms of the common cold in adults and children. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 6, June 2016), which contains the Cochrane Acute Respiratory Infections (ARI) Specialised Register, MEDLINE (1946 to July 2016), Embase (2010 to 15 July 2016), CINAHL (1981 to 15 July 2016), LILACS (1982 to July 2016), Web of Science (1955 to July 2016) and clinical trials registers...

A new barklouse species belonging to the Trichadenotecnum s.str. clade (Psocodea: "Psocoptera": Psocidae) was described from southeastern Brazil (Minas Gerais state). This locality is highly isolated (about 3400 km) from the closest known distributional range of this clade. It also represents the southernmost distributional record of Trichadenotecnum s.str. Phylogenetic placement of the species and biogeography of Neotropical Trichadenotecnum were briefly discussed. Trichadenotecnum punctipenne New, 1972 described from Brazil was synonymized with Trichadenotecnum pardus Badonnel, 1955...

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...

The long-lived radionuclide (129)I (half-life: 15.7 × 10(6) yr) is well-known as a useful environmental tracer. At present, the global (129)I in surface water is about 1-2 orders of magnitude higher than pre-1960 levels. Since the 1990s, anthropogenic (129)I produced from industrial nuclear fuels reprocessing plants has been the primary source of (129)I in marine surface waters of the Atlantic and around the globe. Here we present four coral (129)I time series records from: 1) Con Dao and 2) Xisha Islands, the South China Sea, 3) Rabaul, Papua New Guinea and 4) Guam...

In this paper we revisit a topic originally discussed in 1955, namely the lack of direct evidence that muscle hypertrophy from exercise plays an important role in increasing strength. To this day, long-term adaptations in strength are thought to be primarily contingent on changes in muscle size. Given this assumption, there has been considerable attention placed on programs designed to allow for maximization of both muscle size and strength. However, the conclusion that a change in muscle size affects a change in strength is surprisingly based on little evidence...

The eminent entomologist Aristide Caradja (1861-1955) published between 1925 and 1939, on his own or jointly with Edward Meyrick, a series of taxonomic papers on Chinese microlepidoptera including the descriptions of 18 new species in Yponomeutidae (Hyponomeutidae of authors). Their type specimens are currently deposited in two institutions, the Natural History Museum in London (BMNH: formerly British Museum of Natural History), as previously incorporated in the Meyrick collection, and the "Grigore Antipa" National Museum of Natural History in Bucharest, Romania (MGAB), as incorporated in the Caradja collection...

Acasta sulcata spinosa Daniel, 1955 has been discovered to be a junior homonym of Acasta spinosa Hiro, 1939. As both names were originally described in the genus Acasta, ICZN (International Commission on Zoological Nomenclature) Article 57.2 defines A. sulcata spinosa as a primary junior homonym, even though it is of subspecific nature.

To deride the hope of progress is the ultimate fatuity, the last word in poverty of spirit and meanness of mind. There is no need to be dismayed by the fact that we cannot yet envisage a definitive solution of our problems, a resting-place beyond which we need not try to go. -P.B. Medawar, 1969* [Formula: see text] Thomas E. Starlz, also known as the Father of Clinical Transplantation, once said that organ transplantation was the supreme exception to the rule that most major advances in medicine spring from discoveries in basic science [Starzl T...

Phenological changes in key seasonally expressed life-history traits occurring across periods of climatic and environmental change can cause temporal mismatches between interacting species, and thereby impact population and community dynamics. However, studies quantifying long-term phenological changes have commonly only measured variation occurring in spring, measured as the first or mean dates on which focal traits or events were observed. Few studies have considered seasonally paired events spanning spring and autumn or tested the key assumption that single convenient metrics accurately capture entire event distributions...

Pancreatic stromal fibroblasts provide structural support. Activated fibroblasts are critical in the tumor microenvironment. In this issue of Genes & Development, Liu and colleagues (pp. 1943-1955) unravel the finding that depletion of Smoothened (Smo) in pancreatic stromal fibroblasts results in AKT activation and noncanonical GLI2 activation with subsequent TGFα secretion, activation of EGFR in pancreatic epithelial cells, and augmentation of acinar-ductal metaplasia. Additionally, Smo-mediated signaling has proproliferative effects on pancreatic tumor cells...

BACKGROUND: Working in anaesthesia is stressful, but also satisfying. Work-related stress can have a negative impact on mental health, whereas work-related satisfaction protects against these harmful effects. OBJECTIVE(S): How work stress and satisfaction are experienced may be related to personality. Our aim was to study the relationship between personality and perception of work in a sample of Dutch anaesthesiologists. DESIGN: Questionnaire survey...

Plateurytion roigi sp. nov. (Chilopoda: Geophilomorpha: Geophilidae) is fully described and illustrated from the holotype female from southern Chile (Region X (de Los Lagos region): Palena province). The new species seems particularly similar to P. gracilis (Gervais, 1849) (from Chile and Argentina), to which it is accordingly compared in detail for a confident identification. This is the sixth report of a species of the genus Plateurytion Attems, 1909, from Chile. The others are P. gracilis (Gervais, 1849); P...

An approximately 59-year (1955-2014) sedimentary record of metal elements (Cu, Pb, Zn, Ni, Co, Mn, and Fe) in a sediment core, collected from the Huaihe River, Huainan City, Anhui Province, China, was reconstructed by using (210)Pb geochronology. Copper, Zn, Ni, Co, and Mn evaluated by enrichment factor (EF) indicated minor contamination due to water pollution accidents of the Huaihe River that occurred in 1990s and 2004. Lead presented the most severe pollution among the metals studied, especially during 1957-1974...
