BACKGROUND: The early prediction of the severity of acute pancreatitis still represents a challenge for clinicians. Experimental studies have revealed the generation of specific halogenated lipids, in particular oleic acid chlorohydrin, in the early stages of acute pancreatitis. We hypothesized that the levels of circulating oleic acid chlorohydrin might be a useful early prognostic biomarker in acute pancreatitis in humans. METHODS: In a prospective, multicenter cohort study, plasma samples collected within 24 h after presentation in the emergency room from 59 patients with acute pancreatitis and from 9 healthy subjects were assessed for oleic acid chlorohydrin levels...

BACKGROUND: The antifeedant activity of 18 sesquiterpenoids of the drimane family (polygodial, drimenol and derivatives) was investigated. The results of this study against two insect species, Spodoptera frugiperda and Epilachna paenulata showed that polygodial, drimanic and nordrimanic derivatives exert antifeedant effects in these pests of agronomic interest indicating that they have potential as a biopesticide agent. RESULTS: Among the 18 compounds tested, the epoxynordrimane compound (11) and isonordrimenone (4) showed itself the highest activity (EC50 = 23...

This field study investigated the consequences of receiving poverty aid through conditional transfer programmes in the form of autonomy-oriented help (i.e., cash) or dependency-oriented help (i.e., vouchers) in impoverished rural communities in Panama. The empowering effects of autonomy- (vs. dependency-) help have so far only been studied in laboratory settings, or in settings where help could easily be refused. Little is known about the reactions of people who rely on help for extended periods of time. This study provides insights into how aid recipients are influenced by the type of aid they receive...

The 3-D inverse modelling of a magnetic anomaly measured over the NW submarine edifice of the volcanic island of Gran Canaria revealed a large, reversely-magnetized, elongated structure following an ENE-WSW direction, which we interpreted as a sill-like magmatic intrusion emplaced during the submarine growth of this volcanic island, with a volume that could represent up to about 20% of the whole island. The elongated shape of this body suggests the existence of a major crustal fracture in the central part of the Canary Archipelago which would have favoured the rapid ascent and emplacement of magmas during a time span from 0...

The type 2 diabetes mellitus epidemic threatens public healthcare systems worldwide. Efforts to prevent chronic complications of diabetes and reduce their associated mortality have been ineffective. Hence, early prevention of type 2 diabetes mellitus and cardiovascular disease needs to be prioritized. This strategy, however, must be centered not on an approach based on hyperglycemia but on early pathophysiologic mechanisms, such as insulin resistance. Non-alcoholic fatty liver disease, androgenic alopecia, acanthosis nigricans, and polycystic ovarian syndrome are all well-accepted early clinical manifestations of insulin resistance that represent, in themselves, a risk for further development of type 2 diabetes and that appear years before hyperglycemia...

Homoeologous exchanges (HEs) have been shown to generate novel gene combinations and phenotypes in a range of polyploid species. Gene presence/absence variation (PAV) is also a major contributor to genetic diversity. In the present study we show that there is an association between these two events, particularly in recent Brassica napus synthetic accessions, and that these represent a novel source of genetic diversity, which can be captured for the improvement of this important crop species. By assembling the pangenome of B...

We present an atypical case of disseminated cutaneous leishmaniasis in the Sihuas district, located in the Andean valleys of Ancash-Peru. A 62-year-old man with no particular medical history presented multiple lesions located on the inferior abdomen, lumbar region and the right anterior thigh. Histological analysis found leishmanial amastigotes in the lesion sample, the Montenegro reaction was positive for Leishmania spp, and the polymerase chain reaction was positive for Leishmania peruviana. In conclusion, the atypical presentation of this disease may be related to the presence of an uncommon parasite strain or host immune deficiencies...

From 2004 to 2014, 106 cases of Human haemorrhagic fever with renal syndrome were notified in Montenegro, with a peak in 2014. Most of the cases occurred in summer, in the North-east and Central Montenegro, a hilly/mountainous area, that provides suitable habitats for the main rodent carriers. Cases were mainly males (71) and exposures were often working outdoor or spending time visiting mountains and lakes. Incidence correlated with average annual temperature increase and average annual rainfalls decrease, but not with land cover...

There is little information on the presence of the Mycobacterium avium-Intracellulare (MAC) complex in Peru. Five cases of MAC infection are described in patients with HIV/AIDS at the National Hospital Dos de Mayo, Lima - Peru. The patients presented, mainly, persistent fever, chronic diarrhea, consumptive syndrome, pancytopenia and citofagocitosis. In all of them, resistant acid-alcohol bacilli were identified in feces, so they received antituberculous treatment. The culture of feces was negative for Mycobacterium tuberculosis and, later, in all cases MAC was identified using a molecular test (genotype) in the culture of feces...
