Genomic data of global clones of CTX-M-65-producing Escherichia coli ST10 from South American llamas inhabiting the Andean Highlands of Peru.

Background: The global spread of extended-spectrum β-lactamase (ESβL)-producing Escherichia coli has been considered a One Health issue that demands continuous genomic epidemiology surveillance in humans and non-human hosts.

Objectives: To report the occurrence and genomic data of ESβL-producing E. coli strains isolated from South American llamas inhabiting a protected area with public access in the Andean Highlands of Peru.

Genomic analysis of multidrug-resistant Escherichia coli strains carrying the mcr-1 gene recovered from pigs in Lima-Peru.

Antibiotic resistance is a current problem that significantly impacts overall health. The dissemination of antibiotic resistance genes (ARGs) to urban areas primarily occurs through ARG-carrying bacteria present in the gut microbiota of animals raised in intensive farming settings, such as pig production. Hence, this study aimed to isolate and analyzed 87 Escherichia coli strains from pig fecal samples obtained from intensive farms in Lima Department.

Hydropneumothorax in Children: A Rare Complication of a Bacterial Pneumonia.

Hydropneumothorax is an uncommon presentation of a complicated pneumonia, and very few cases in the pediatric population have been reported. This is a case of a 5-month-old patient who presented to the emergency department (ED) with a three-day history of fever, diarrhea, and respiratory distress. His initial assessment suggested a lower respiratory tract infection and because of his respiratory distress and hypoxia a chest X-ray was performed.

[Effect of red maca (Lepidium meyenii) on INF-γ levels in ovariectomized rats].

Objectives: Compare the effect of different doses of red maca on gamma interferon (IFN-γ) levels in ovariectomized rats (OVX).

Materials And Methods: Adult female rats were randomly divided into the following six groups: Group 1: pseudo-ovariectomized rats (PO); Group 2: OVX rats; Group 3: OVX rats treated with 4 ug/kg estradiol; and Group 4, 5 and 6: OVX rats treated with red maca extracts with 2.15, 4.

[Maca (Lepidium meyenii Walp), a review of its biological properties].

Maca (Lepidium meyenii) is a plant that grows above 4000 altitude meters in Peru's Central Andes; it has different varieties according to the color of the hypocotyl. This review summarizes the results of studies about the effects of maca on sexual function, spermatogenesis, female reproductive function, memory, depression and anxiety, and energy as well as effects on benign prostatic hyperplasia, osteoporosis and metabolic syndrome. Its anti-aging effect is also discussed as well as safety in consumption.

A randomized, double-blind placebo-controlled study on acceptability, safety and efficacy of oral administration of sacha inchi oil (Plukenetia volubilis L.) in adult human subjects.

The study was designed to assess acceptability and side-effects of consumption of sacha inchi oil, rich in α-linolenic acid and sunflower oil, rich in linoleic acid, in adult human subjects. Thirty subjects received 10 or 15ml daily of sacha inchi or sunflower oil for 4months. Acceptability was assessed with daily self-report and with a Likert test at the end of the study.

Exposure of fatty acids after a single oral administration of sacha inchi (Plukenetia volubilis L.) and sunflower oil in human adult subjects.

Context: Sacha inchi (Plukenetia volubilis L.) is a potential oilseed crop because it is rich in α-linolenic acid (ALA) (omega-3 fatty acid).

Objective: To evaluate the exposure of fatty acids after a single oral administration of sacha inchi or sunflower oil in healthy volunteers.

Effects of different varieties of Maca (Lepidium meyenii) on bone structure in ovariectomized rats.

Objective: This study was designed to determine the effect of different varieties of maca (Lepidium meyenii) on bone structure in ovariectomized (OVX) rats.

Materials And Methods: 36 female rats were randomly divided into 6 groups: sham and OVX rats treated with vehicle, estradiol (40 microg/kg), black, yellow or red maca (63 mg/ml) for 4 weeks. At the end of the treatment, uterine weight, femoral bone and lumbar vertebra histomorphology were assessed.

Lepidium meyenii (Maca): a plant from the highlands of Peru--from tradition to science.

This review summarizes the current state of knowledge on Lepidium meyenii (maca), a cruciferous plant (Brassicaceae family) which is cultivated exclusively at an altitude of 4,000-4,500 m in the Peruvian Central Andes. Maca is traditionally used for its nutritional and presumed medicinal properties. Over the past 20 years, interest in maca has increased in many parts of the world, and since 2005 maca is considered one of the seven Peruvian flag products.

Semen quality and reproductive sex hormone levels in Peruvian pesticide sprayers.

To determine the association between occupational pesticide exposure and semen quality among sprayers using organophosphate (OPs) pesticides, 31 pesticide sprayers and 80 men who were not exposed were studied. Semen and blood samples were obtained one day after last pesticide application. Semen samples were analyzed for sperm concentration, percentage of sperm motility, percentage of normal morphology, and fructose and zinc concentrations.

Effect of short-term and long-term treatments with three ecotypes of Lepidium meyenii (MACA) on spermatogenesis in rats.

Lepidium meyenii (Brassicaceae), known as Maca, is a Peruvian hypocotyl that grows exclusively between 4000 and 4500 m above sea level in the central Andes. Maca is traditionally employed in the Andean region for its supposed fertility-enhancing properties. The study aimed to test the hypothesis that different ecotypes of Maca (Red, Yellow and Black) after short-term (7 days) and long-term (42 days) treatment affects differentially spermatogenesis adult rats.

Lead exposure and semen quality among traffic police in Arequipa, Peru.

This study examined lead exposure (n = 43) and semen quality (n = 18) among traffic police officers in Arequipa, Peru, where leaded gasoline is used. Blood lead (PbB) was measured using atomic absorption spectrophotometry, and semen was analyzed following World Health Organization (WHO) protocol. Mean PbB was 48.

Dose-response effects of Lepidium meyenii (Maca) aqueous extract on testicular function and weight of different organs in adult rats.

Lepidium meyenii (Brassicaceae) known as Maca grows exclusively between 4000 and 4500 m over the sea level in the Peruvian central Andes. The dried hypocotyls of Maca are traditionally used as food and for its supposed fertility-enhancing properties. A dose-response study was performed to determine the effect of 7 days oral administration of an aqueous lyophilized extract of Maca at 0.
