Effect of the Soil pH on the Alkaloid Content of Lupinus angustifolius

open access: yesInternational Journal of Agronomy, 2012
Field studies were conducted in growing seasons 2004, 2005, and 2010 to investigate the effect of different soil pH values on the alkaloid content in seeds of Lupinus angustifolius.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Zero tolerance policing: new authoritarianism or new liberalism? [PDF]

open access: yes, 2002
The notion of “zero tolerance” policing has been widely discussed in the media in recent years and has received considerable support from politicians right across the political spectrum both in the USA and the UK. Proponents of this apparently “get-tough”

Helminths and immunological tolerance [PDF]

open access: yes, 2014
Current immunosuppression regimens for solid-organ transplantation have shown disappointing efficacy in the prevention of chronic allograft rejection and carry unacceptable risks including toxicity, neoplasia, and life-threatening infection.

Development of Tolerance and Gross Tolerance by Mephobarbital.

open access: yesExperimental Biology and Medicine, 1952
Summary(1) Repeated daily intravenous injections of mephobarbital produces tolerance in experimental animals (rabbits). (2) The development of tolerance to mephobarbital also produces cross tolerance to butabarbital sodium.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Experimental Design to Determine Drought Stress Response and Early Leaf Senescence in Barley (Hordeum vulgare L.)

open access: yesBio-Protocol, 2016
Premature leaf senescence induced by drought stress is a main factor for yield losses in barley. Research in drought stress tolerance has become more important as due to climate change the number of drought periods will increase and tolerance to drought ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

School violence and teachers' perception of the zero tolerance policy [PDF]

open access: yes, 2002
Plan BThis study examined teachers’ perception of the zero tolerance policy. The goal was to identify the benefits, drawbacks, and perceived effectiveness of the zero tolerance policy as a preventative tool against school violence.
