Potential Roles of n-3 PUFAs during Skeletal Muscle Growth and Regeneration
Author:  Bill TachtsisOrcID, Donny Camera and Orly Lacham-Kaplan

Omega-3 polyunsaturated fatty acids (n-3 PUFAs), which are commonly found in fish oil supplements, are known to possess anti-inflammatory properties and more recently alter skeletal muscle function. In this review, we discuss novel findings related to how n-3 PUFAs modulate molecular signaling responsible for growth and hypertrophy as well as the activity of muscle stem cells. 

Skeletal Muscle Repair
Muscle stem cells commonly known as satellite cells, are primarily responsible for driving the skeletal muscle repair process to potentially damaging stimuli, such as mechanical stress elicited by exercise contraction. To date, there is a paucity of human investigations related to the effects of n-3 PUFAs on satellite cell content and activity. Based on current in vitro investigations, this review focuses on novel mechanisms linking n-3 PUFA’s to satellit…

Why do forest products become less available?: A pan-tropical comparison of drivers of forest resource degradation

Authors: Hermans-Neumann, K.; Gerstner, K.; Geijzendorffer, I.R.; Herold, M.; Seppelt, R.; Wunder, S.
Forest products provide an important source of income and wellbeing for rural smallholder communities across the tropics. Although tropical forest products frequently become over-exploited, only few studies explicitly address the dynamics of degradation in response to socio-economic drivers. Our study addresses this gap by analyzing the factors driving changes in tropical forest products in the perception of rural smallholder communities. Using the poverty and environment network global dataset, we studied recently perceived trends of forest product availability considering firewood, charcoal, timber, food, medicine, forage and other forest products. We looked at a pan-tropical sample of 233 villages with forest access. Our results show that 90% of the villages experienc…

Lula’s defense to further appeal against imprisonment

Attorney Cristiano Zanin, of former President Luiz Inácio Lula da Silva’s defense team, said Lula is outraged, but fine. Zanin said he only talked to the onetime leader at the Federal Police prison unit Sunday (Apr. 8), but added he could not get into further detail as it was a lawyer–client meeting.


Zanin confirmed that Lula’s defense team is to continue to take measures to reverse his client’s jail sentence, and said his lawyers have considered requesting having Lula relocated to São Paulo. “I’m not at liberty to reveal the strategies of the counsel. We believe there are no legal grounds for him to be incarcerated, and we’ll take action to reverse his jail sentence,” he added.
After keeping vigil for two days at the ABC Metalworkers Trade Union headquarters, in São Bernardo do Campo, São Paulo, Lula turned himself in to the Federal Police on Saturday (7), more than 24 afte…

5 essential reads about Facebook's data crisis

Jeff InglisThe Conversation
Most of Facebook’s 2 billion users have likely had their data collected by third parties, the company revealed April 4. That follows reports that 87 million users’ data were used to target online political advertising in the run-up to the 2016 U.S. presidential election.
As company CEO Mark Zuckerberg prepares to testify before Congress, Facebook is beginning torespond to international public and government criticism of its data-harvesting and data-sharing policies. Many scholars around the U.S. are discussing what happened, what’s at stake, how to fix it, and what could come next. Here we spotlight five examples from our recent coverage.





Understanding Facebook's data crisis: 5 essential reads
1. What actually happened?A lot of the concern has arisen from reporting that indicated Cambridge Analytica’s analysis was based on profiling people’s personalities, based on work from Cambridge University researche…

Reading comprehension - Superstition in Brazil
SUPERSTITION
There is evidence of superstition among ancient civilizations. But this is not something of the past. Superstition is part of our modern world, too. 
Some very old beliefs are present among us today: a broken mirror, for example, means seven years of bad luck. A black cat brings you bad luck when it crosses your way. Some people never walk under a ladder because it also means bad luck. New Yorkers, for example, believe that 13 is a sign......... bad luck and many buildings have........... thirteenth floor.

There is also a place for good luck superstition. Some charms and beliefs are popular because they bring good luck. A horseshoe, for example, or a four-leaf clover are popular good luck charms around the world. In Brazil, it is very difficult .......... find a ticket of the Federal Lottery with a final 13 because this is the lucky number. There is another curious belief in Brazil which states that if you give three kisses on th…
