A fundamental challenge in machine learning today is to build a model that can learn from few examples. Here, we describe a reservoir based spiking neural model for learning to recognize actions with a limited number of labeled videos. First, we propose a novel encoding, inspired by how microsaccades influence visual perception, to extract spike information from raw video data while preserving the temporal correlation across different frames. Using this encoding, we show that the reservoir generalizes its rich dynamical activity toward signature action/movements enabling it to learn from few training examples...

Retinal nerve fiber layer defect (RNFLD) provides an early objective evidence of structural changes in glaucoma. RNFLD detection is currently carried out using imaging modalities like OCT and GDx which are expensive for routine practice. In this regard, we propose a novel automatic method for RNFLD detection and angular width quantification using cost effective redfree fundus images to be practically useful for computer-assisted glaucoma risk assessment. After blood vessel inpainting and CLAHE based contrast enhancement, the initial boundary pixels are identified by local minima analysis of the 1-D intensity profiles on concentric circles...

Treatments of patient with amlodipine (a calcium channel blocker, CCB) overdose/poisoning remain challenging and death is certain if not intervened timely. Furthermore, for a society, the availability and common use of this drug make more vulnerable, especially by children, towards an accidental/suicidal poisoning. Here we describe an adolescent school girl who took 150 mg of amlodipine and was admitted in our hospital approximately 4 hours after ingestion with suicidal intention. She developed circulatory failure and tachypnea...

The giant panda, with an estimated population size of 2239 in the world (in 2015), is a global symbol of wildlife conservation that is threatened by habitat loss, poor reproduction and limited resistance to some infectious diseases. Of these factors, some diseases caused by parasites are considered as the foremost threat to its conservation. However, there is surprisingly little published information on the parasites of the giant panda, most of which has been disseminated in the Chinese literature. Herein, we review all peer-reviewed publications (in English or Chinese language) and governmental documents for information on parasites of the giant pandas, with an emphasis on the intestinal nematode Baylisascaris schroederi (McIntosh, 1939) as it dominates published literature...

Carnivorous members of the Carnivora reside at the apex of food chains and consume meat-only diets, rich in purine, fats and protein. Here, we aimed to identify potential adaptive evolutionary signatures compatible with high purine and fat metabolism based on analysis of host genomes and symbiotic gut microbial metagenomes. We found that the gut microbiomes of carnivorous Carnivora (e.g. Felidae, Canidae) clustered in the same clade, and other clades comprised omnivorous and herbivorous Carnivora (e.g. badgers, bears and pandas)...

PURPOSE: This study demonstrates a DCE-MRI estimate of tumor interstitial fluid pressure (TIFP) and hydraulic conductivity in a rat model of glioblastoma, with validation against an invasive wick-in-needle (WIN) technique. An elevated TIFP is considered a mark of aggressiveness, and a decreased TIFP a predictor of response to therapy. METHODS: The DCE-MRI studies were conducted in 36 athymic rats (controls and posttreatment animals) with implanted U251 cerebral tumors, and with TIFP measured using a WIN method...

Primary hepatic lymphoma (PHL) is an extremely rare disease and is often misdiagnosed. The optimal therapy is still unclear and the outcomes are uncertain. Among PHLs, a primary hepatic low-grade marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue is still rarer. The present study reports the case of an elderly female diagnosed with PHL (mucosa-associated lymphoid tissue) and treated with single agent rituximab. After 18 months, she had a progressive disease and developed Waldenstorms macroglobulinemia concomitantly...

The red panda ( Ailurus fulgens) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The aim of this study was to describe the normal radiographic abdominal anatomy in red pandas to provide guidance for clinical use. Radiography of the abdomen was performed in nine captive red pandas during their annual health examinations. Seven of nine animals had six lumbar vertebrae. The sacrum consisted mainly (8/9) of three fused segments. Hypaxial muscles were easily seen in animals weighing 5 kg and above...

Accurate optic disc (OD) segmentation is an important step in obtaining cup-to-disc ratio-based glaucoma screening using fundus imaging. It is a challenging task because of the subtle OD boundary, blood vessel occlusion and intensity inhomogeneity. In this Letter, the authors propose an improved version of the random walk algorithm for OD segmentation to tackle such challenges. The algorithm incorporates the mean curvature and Gabor texture energy features to define the new composite weight function to compute the edge weights...

Physiological factors controlling assimilate partitioning was compared in relation to panicle architecture of lax- (Upahar) and compact-panicle (Mahalaxmi) rice cultivars. Grain number and ethylene production at anthesis are low, but filling rate is high in the former compared to high grain number and ethylene production and poor filling trait of the latter. Similar to Mahalaxmi, its progenitors Pankaj and Mahshuri, had attributes of high grain number and grain density, but grain filling was higher and ethylene evolution was lower...

Plasmodium  falciparum Merozoite surface protein (MSP) 1 has been studied extensively as a vaccine candidate antigen. PfMSP-1 undergoes proteolytic processing into four major products; p83, p30, p38 and p42 that are associated in the form of non-covalent complex(s) with other merozoite surface proteins. To delineate MSP1 regions involved in the interaction with other MSPs, here we expressed recombinant proteins (PfMSP-165 ) encompassing part of p38 and p42 regions and PfMSP-119 PfMSP-165   interacted strongly with PfMSP-3, PfMSP-6, PfMSP-7, PfMSP-9, whereas PfMSP-119 did not interact with any of these proteins...

Bamboo-eating giant panda ( Ailuropoda melanoleuca ) is an enigmatic species, which possesses a carnivore-like short and simple gastrointestinal tract (GIT). Despite the remarkable studies on giant panda, its diet adaptability status continues to be a matter of debate. To resolve this puzzle, we investigated the functional potential of the giant panda gut microbiome using shotgun metagenomic sequencing of fecal samples. We also compared our data with similar data from other animal species representing herbivores, carnivores, and omnivores from current and earlier studies...

Pain is one of the most feared of all symptoms for the cancer patient. Some studies estimate that up to 90% of all cancer patients experience pain. Advances in pharmaceuticals and expert provider knowledge have improved pain management overall for the patient with cancer; however, complementary therapies can synergize medications to provide optimal pain relief while decreasing the side effect profile. Despite this, nurses may have limited access to such resources. Many therapies can be administered directly by the bedside/chairside nurse with minimal training and the nurse can then teach the patient and family how to use the selected complementary therapy after leaving the hospital or clinic...
