(Photosynthetic responses of tropical tree species from different successional groups under contrasting irradiance conditions). This study evaluated the photosynthetic responses of seven tropical trees of different successional groups under contrasting irradiance conditions, taking into account changes in gas exchange and chlorophyll a fluorescence. Although early successional species have show...

The ability to modify/visualize biological surfaces, and then study the modified cell/virion in a range of in vitro and in vivo environments is essential to gaining further insight into the function of specific molecules or the entire entity. Studies of biological surface modification are generally limited to genetic engineering of the organism or the covalent attachment of chemical moieties to...

The ability to glycosylate surfaces has medical and diagnostic applications, but there is no technology currently recognized as being able to coat any surface without the need for prior chemical modification of the surface. Recently, a family of constructs called function-spacer-lipids (FSL) has been used to glycosylate cells. Because it is known that lipid-based material can adsorb onto surfac...

BACKGROUND Fine-needle aspiration (FNA) of focal splenic lesions (FSL) is usually done under ultrasound (US) or computed tomography guidance. Endoscopic US (EUS), because of its ability to provide high-resolution images, can be used for aspirating FSL. We studied the safety and efficacy of EUS-guided FNA of FSL. METHODS We performed a retrospective analysis of patients with FSL undergoing EUS...

Animal models have been used in understanding the neuro-biological basis of depression and predicting successful treatment strategies. The current study focused on two genetic models of depression, the Flinder's Sensitive Line (FSL) and Wister-Kyoto (WKY). Our laboratory showed depressive symptomatology in pre-pubertal WKY and FSL rats, and the current study focused on the strains' anxiety-like...

One of the most important criteria for major depressive disorder in adults and in children and adolescents as well, is the loss of interest in or pleasure from typically enjoyable experiences or activities: anhedonia. Anxiety is frequently co-morbid with depression. We examined reward and anxiety in genetic animal models of childhood depression. Two different "depressed" lines were studied: the...

OBJECTIVE Clinical depression is associated with multiple abnormalities of immune function, including reduced virus-specific responses. This study tested the hypothesis that the Flinders Sensitive Line (FSL) rat, a promising genetic animal model of depression, would exhibit reductions in antigen-specific primary antibody responses to immunization. METHODS FSL (N = 13) and control Flinders Res...

We explore few-shot learning (FSL) for relation classification (RC). Focusing on the realistic scenario of FSL, in which a test instance might not belong to any target categories (none-of-the-above, [NOTA]), we first revisit recent popular dataset structure pointing out its unrealistic data distribution. To remedy this, propose novel methodology deriving more from available datasets supervised ...

Serotonin (5HT) is crucial to normal reflex vagal modulation of heart rate (HR). Reduced baroreflex sensitivity (sBRS) and HR variability (HRV) reflect impaired neural, particularly vagal, control of HR and are independently associated with depression. In conscious, telemetered Flinders-Sensitive Line rats (FSL), a well-validated animal model of depression, we tested the hypothesis that cardiov...

There is accumulating evidence that brain-derived neurotrophic factor (BDNF) plays a critical role in the pathophysiology of depression. Decreased serum levels have been reported in major depression, and a correlation between BDNF reduction and the severity of the disease was found. Moreover, in post-mortem hippocampal tissue, increased levels of BDNF immunoreactivity have been reported in subj...
