We report a case of non-immune hydrops fetalis (NIHF) caused by herpes simplex virus type 2 (HSV-2) in an infant whose mother had recurrent HSV-2 infection. In spite of prematurity, severe disseminated infection and hydrops, the infant survived and was neurologically intact. HSV-2-induced NIHF is extremely rare, particularly in the ...

Science is marked by the death of dogmas; the discovery that adipocytes are more than just lipid-storing cells but rather produce potent hormones is one such example that caught physiologists by surprise and reshaped our views of metabolism. While we once considered the adipocyte as a passive storage organ for ...

Weak Galerkin methods refer to general finite element methods for partial differential equations (PDEs) in which differential operators are approximated by their weak forms as distributions. Such weak forms give rise to desirable flexibilities in enforcing boundary and interface conditions. A weak Galerkin finite element method (WG-FEM) is developed in ...

The neural organization of semantic memory remains much debated. A 'distributed-only' view contends that semantic knowledge is represented within spatially distant, modality-selective primary and association cortices. Observations in semantic variant primary progressive aphasia have inspired an alternative model featuring the anterior temporal lobe as an amodal hub that supports semantic ...

Antibiotics and probiotics are widely used as growth promoters in agriculture. Most antibiotics prescribed in clinical practice are natural products that originate from Streptomyces spp, which were first used as agricultural probiotics. Antibiotics and probiotics both modify the gut microbiota. The effect of a probiotic species on the digestive flora ...

Autophagy is an evolutionarily-conserved catabolic process initiated by the engulfment of cytosolic components in a crescent-shaped structure, called the phagophore, that expands and fuses to form a closed double-membrane vesicle, the autophagosome. Autophagosomes are subsequently targeted to the lysosome/vacuole with which they fuse to degrade their content. The formation of ...

During the last decade it has become evident that autophagy is not simply a non-selective bulk degradation pathway for intracellular components. On the contrary, the discovery and characterization of autophagy receptors which target specific cargo for lysosomal degradation by interaction with ATG8 (autophagy-related protein 8)/LC3 (light-chain 3) has accelerated our ...

Mitophagy describes the selective targeting and degradation of mitochondria by the autophagy pathway. In this process, defective mitochondria are first purged from the mitochondrial network then delivered to the lysosome by the autophagy machinery. Mitophagy has emerged as a key facet of mitochondrial quality control and has been implicated in ...

Autophagy is intimately associated with eukaryotic cell death and apoptosis. Indeed, in some cases the same proteins control both autophagy and apoptosis. Apoptotic signalling can regulate autophagy and conversely autophagy can regulate apoptosis (and most likely other cell death mechanisms). However, the molecular connections between autophagy and cell death are ...

Autophagy is a process of lysosome-dependent intracellular degradation that participates in the liberation of resources including amino acids and energy to maintain homoeostasis. Autophagy is particularly important in stress conditions such as nutrient starvation and any perturbation in the ability of the cell to activate or regulate autophagy can lead ...

Autophagy is a process that takes place in all mammalian cells and ensures homoeostasis and quality control. The term autophagy [self (auto)-eating (phagy)] was first introduced in 1963 by Christian de Duve, who discovered the involvement of lysosomes in the autophagy process. Since then, substantial progress has been made in ...

Autophagy is a membrane trafficking pathway that results in the formation of autophagosomes which deliver portions of the cytosol to lysosomes for degradation. When autophagosomes engulf intracellular pathogens, the pathway is called 'xenophagy' because it leads to the removal of foreign material. Autophagy is activated during infection by Toll-like receptors ...

The optical properties of single-wall carbon nanotubes are very promising for developing novel opto-electronic components and sensors with applications in many fields. Despite numerous studies performed using photoluminescence or Raman and Rayleigh scattering, knowledge of their optical response is still partial. Here we determine using spatial modulation spectroscopy, over a ...

Topoisomerases resolve torsional stress, while their function in gene regulation, especially during cellular differentiation, remains unknown. Here we find that the expression of topo II isoforms, topoisomerase IIα and topoisomerase IIβ, is the characteristic of dividing and postmitotic tissues, respectively. In embryonic stem cells, topoisomerase IIα preferentially occupies active gene ...

Bridges are commonly used to replace missing teeth. Periodontal health may, however, be compromised by ill-fitting margins and excess cement. This case report describes the conservative management of chronic gingival inflammation adjacent to the resin-bonded retainers of an anterior bridge by gingival remodelling via a removable prosthesis. This avoided the ...

Autophagy is a conserved survival pathway, which cells and tissues will activate during times of stress. It is characterized by the formation of double-membrane vesicles called autophagosomes inside the cytoplasm. The molecular mechanisms and the signalling components involved require specific control to ensure correct activation. The present chapter describes the ...
