Sit-and-wait predators use different strategies to encounter potential prey. Rhinoleucophenga myrmecophaga Vidal et (Vidal et Vilela; Diptera: Drosophilidae) larvae build sticky shelters on top of extrafloral nectaries (EFNs) of Qualea grandiflora Mart (Vochysiaceae), a common plant in the Brazilian cerrado savanna. Although larval shelters block the EFNs, nectar production is not obstructed and is used by the larvae to attract and trap nectar-gathering ants that are eventually eaten by the dipteran. Here we describe the natural history of R...

Lactic acid bacteria (LAB) have a long history in industrial processes as food starters and biocontrol agents, and also as producers of high-value compounds. Lactic acid, their main product, is among the most requested chemicals because of its multiple applications, including the synthesis of biodegradable plastic polymers. Moreover, LAB are attractive candidates for the production of ethanol, polyhydroalkanoates, sweeteners and exopolysaccharides. LAB generally have complex nutritional requirements. Furthermore, they cannot directly ferment inexpensive feedstocks such as lignocellulose...

INTRODUCTION: Pheochromocytomas are infrequent tumors arised from the chromaphine cells of the adrenal sympathetic system. The excess of circulating catecholamines may lead to different cardiovascular disorders from silent alterations of the myocardial conduction to different forms of cardiomyopathy. The onset as cardiogenic shock is exceptional. PRESENTATION OF CASE: A 35-year-old male, with a known history of acute myopericarditis of unknown origin which debuted as acute pulmonary edema, was admitted with dyspnea in the context of a new heart failure episode with pulmonary edema...

A skin biopsy was obtained from a 14-year-old female patient with a history of Myelomeningocele. Dermal fibroblasts were isolated and reprogrammed with Sendai virus (SeV) vectors encoding OCT3/4, SOX2, KLF4, and c-MYC. The generated induced Pluripotent Stem Cell (iPSC) clones NTDi4_09A were free of genomically integrated reprogramming genes, had a stable normal karyotype and expressed pluripotency markers. The iPSCs formed teratomas in mice, which were differentiated towards derivatives of the three germ layers in vivo...

Microbiomes impact nearly all systems on Earth, and despite vast differences among systems, we contend that it is possible and highly beneficial to develop a unified conceptual framework for understanding microbiome dynamics that is applicable across systems. The ability to robustly predict and control environmental and human microbiomes would provide impactful opportunities to sustain and improve the health of ecosystems and humans alike. Doing so requires understanding the processes governing microbiome temporal dynamics, which currently presents an enormous challenge...

Integral projection and matrix population models are commonly used in ecological and conservation studies to assess the health and extinction risk of populations. These models use one (or more) measurable state variable(s), such as size or age, to predict individual performance which, ideally, is the sole determinant of an individual's expected fate. However, even if ecologists successfully identify and measure the observable state variable(s) that best predicts individual fate, we are rarely if ever able to perfectly measure state for many species, especially those with size structure, where total plant biomass or starch stores, for example, may be the best predictors of fate...

AIM: Recently, the measurement of hepatitis B surface antigen and anti-hepatitis B core antigen (HBcAb) and/or anti-hepatitis B surface antigen is recommended before various therapies to identify the patients at risk of HBV reactivation. However, a recent study reported that HBV reactivation occurred in HBcAb negative patients, indicating that it is challenging to identify patients with a history of HBV infection using conventional HBcAb reagent. We developed a highly sensitive HBcAb (HBcAb-HS) assay for reducing of the HBV reactivation risk...

PURPOSE: Crossed cerebellar (CC) diaschisis refers to a decrease in cerebellar perfusion in the presence of contralateral supratentorial lesions. Most of the previous studies have examined stroke patients. In contrast to strokes, seizure-related cerebral cortical lesions (SCCLs) usually show hyperperfusion, and therefore, cerebellar perfusion patterns are expected to be different from those of strokes. With arterial spin labelling (ASL), we evaluated the cerebellar perfusion status in patients with SCCLs...

INTRODUCTION: Pediatric spinal tuberculosis is characterized by rapid bone destruction and carries the risk of rapid onset neurological deficits and severe deformity of the spine. Behavior of spinal deformity over time is affected by growth of spine. Owing to this dynamic behavior of pediatric spinal tuberculosis both in active phase and in healed phase, it presents with challenges which are quite different from adults with caries spine. A clinician must have high index of suspicion for accurate and early diagnosis of spinal tuberculosis in the pediatric population and should also have a thorough knowledge of differences in natural history between adult and pediatric spinal tuberculosis...
