High human exposure to pyrene (polycyclic aromatic hydrocarbon) in Kinshasa, a capital of the Democratic Republic of Congo

submitted by napimbreon 16 minutes ago - Topic: Health

Data on human exposure to chemicals in Africa are scarce. A biomonitoring study was conducted in a representative sample of the population in Kinshasa (Democratic Republic of Congo) to document exposure to polycyclic aromatics hydrocarbons. 1-hydroxypyrene (1-OHP) was measured by HPLC fluorescenc...

Neuropsychological functioning predicts community outcomes in affective and non-affective psychoses: A 6-month follow-up

submitted by foizihkofe 17 minutes ago - Topic: Health

Neurocognitive dysfunction is a major symptom feature of schizophrenia and bipolar disorder. A prognostic relationship between cognition and community outcomes is well-documented in schizophrenia and increasingly recognized in bipolar disorder. However, specific associations among neurocognition,...

Study Design and Rationale of “A Multicenter, Open-Labeled, Randomized Controlled Trial Comparing Three 2nd-Generation Drug-Eluting Stents in Real-World Practice” (CHOICE trial)

submitted by ixplarir28 20 minutes ago - Topic: Health

The second-generation drug-eluting stents (DES) have shown superiority in many studies relating to safety and efficacy when compared with the first-generation DES. However, it is unclear whether there are differences in efficacy and safety among the second-generation DES after long-term follow-up...

Risk for recurrent coronary heart disease and all-cause mortality among individuals with chronic kidney disease compared with diabetes mellitus, metabolic syndrome, and cigarette smokers

submitted by ixplarir28 20 minutes ago - Topic: Health

Lipid-lowering guidelines endorse a low-density lipoprotein cholesterol goal of <100 mg/dL for people with coronary heart disease (CHD). A more stringent threshold of <70 mg/dL is recommended for those with CHD and “very high-risk” conditions such as diabetes mellitus, metabolic...

Age at Fontan procedure impacts exercise performance in adolescents: Results from the Pediatric Heart Network Multicenter study

submitted by ixplarir28 20 minutes ago - Topic: Health

Most single ventricle patients undergo Fontan procedure in a staged manner. However, optimal timing of Fontan completion after an intermediate staging surgery is controversial. Therefore, we investigated the long-term impact of age at Fontan completion on the exercise performance in adolescents. ...

Characterization of Iraqi sheep milk lysozyme with respect to molecular weight and hydrolytic activity

submitted by egbamog 21 minutes ago - Topic: Agriculture

Lysozyme is an enzyme that can be found in egg white, milk of various species, as well as in animal tissues and secretions and it is antimicrobial to Gram-positive bacteria. The objective of this work was to purify and characterize lysozyme from Iraqi sheep milk with respect to molecular weight a...

Detection of leachables and cytotoxicity after exposure to methacrylate- and epoxy-based root canal sealers in vitro

submitted by jeddocattan 22 minutes ago - Topic: Health

Root canal sealing materials may have toxic potential in vitro depending on the cell line, cytotoxicity assay, material chemistry, and degree of polymer curing. The aims of the present study were to detect leaching components from epoxy- or methacrylate-based root canal sealers and to investigate...

Video Consultation Use by Australian General Practitioners: Video Vignette Study

submitted by sahamplontotean 25 minutes ago - Topic: Health

There is unequal access to health care in Australia, particularly for the one-third of the population living in remote and rural areas. Video consultations delivered via the Internet present an opportunity to provide medical services to those who are underserviced, but this is not currently routi...

Comparative analysis of primary repair vs resection and anastomosis, with laparostomy, in management of typhoid intestinal perforation: results of a rural hospital in northwestern Benin

submitted by sflonniry2 26 minutes ago - Topic: Health

The objective is to compare primary repair vs intestinal resection in cases of intestinal typhoid perforations. In addition, we hypothesised the usefulness of laparostomy for the early diagnosis and treatment of complications. 111 patients with acute peritonitis underwent emergency laparotomy: nu...

Richness and Abundance of Ichneumonidae in a Fragmented Tropical Rain Forest

submitted by notaripradacts 27 minutes ago - Topic: Agriculture

Because of the magnitude of land use currently occurring in tropical regions, the local loss of animal species due to habitat fragmentation has been widely studied, particularly in the case of vertebrates. Many invertebrate groups and the ichneumonid wasps in particular, however, have been poorly...

Citrus fertigation – a technology of water and fertilizers saving

submitted by oleghell 29 minutes ago - Topic: Agriculture

Fertigation is the application of soluble fertilizers through micro-irrigation systems, has been used in citrus production since the 1960s. Originally, fertigation was used in arid regions to improve solubility of fertilizers in the root zone and increase uptake efficiently by fruit trees. Withou...

BAK multimerization for apoptosis, but not bid binding, is inhibited by negatively charged residue in the BAK hydrophobic groove

submitted by hamdastoro 30 minutes ago - Topic: Health

BCL-2 family proteins BAK and BAX orchestrate outer mitochondrial membrane permeabilization (MOMP) during apoptosis by forming pores in the membrane to release apoptogenic factors that commits a cell to death. BAK and BAX therefore function as a 'point of no return' in the apoptotic cascade. BAK ...

Autosomal and uniparental portraits of the native populations of Sakha (Yakutia): implications for the peopling of Northeast Eurasia

submitted by omoloa 32 minutes ago - Topic: Biology

Sakha -- an area connecting South and Northeast Siberia -- is significant for understanding the history of peopling of Northeast Eurasia and the Americas. Previous studies have shown a genetic contiguity between Siberia and East Asia and the key role of South Siberia in the colonization of Siberi...

Parasitic plants have increased rates of molecular evolution across all three genomes

submitted by omoloa 32 minutes ago - Topic: Biology

Theoretical models and experimental evidence suggest that rates of molecular evolution could be raised in parasitic organisms compared to non-parasitic taxa. Parasitic plants provide an ideal test for these predictions, as there are at least a dozen independent origins of the parasitic lifestyle ...
