Adjunctive minocycline microspheres Posted: 19 Mar 2016 07:42 AM PDT The aim of this study was to compare the effects of adjunctive Minocycline HCl Microspheres (Arestin) with debridement alone on the levels of 40 subgingival bacterial species in the treatment of peri-implantitis. Reseachers recruited 208 subjects (from 11 centers in the USA) with at least 1 implant with peri-implantitis and randomized to receive either mechanical debridement alone (n=104) or mechanical debridement followed by Arestin (1 mg) (n=104) at baseline and day 90.

Mama’s boys are not losers in spotted hyenas Posted: 18 Mar 2016 03:17 PM PDT Males that stay at home are not second-class males but can breed as successfully as their more adventurous competitors that leave home, a new long-term study on spotted hyenas shows.

Before retinal cells die, they regenerate, blindness study finds Posted: 18 Mar 2016 03:17 PM PDT In a new study, researchers have shown that retinal cells in three distinct forms of canine early-onset blindness possess an unexpected feature: they temporarily rejuvenate. Further investigation into the reasons for this period of retinal neuron proliferation could lead to molecular targets for intervening in cell death and maintaining functional photoreceptor cells and a working retina.

China's forest recovery shows hope for mitigating global climate change Posted: 18 Mar 2016 03:16 PM PDT China's sweeping program to restore forests across the country is working. The vast destruction of China's forests, leveled after decades of logging, floods and conversion to farmland, has become a story of recovery, according to the first independent verification.

Computer-assisted approaches as decision support systems serving to combat the Zika virus Posted: 18 Mar 2016 03:16 PM PDT No drug is known to treat ZIKV infection; neither do we have any vaccine which can prevent the spread of it. While scientists are trying to cope with the situation, computer-assisted approaches may help as decision support systems.

Turn mortal enemies into allies? Ants can Posted: 18 Mar 2016 03:16 PM PDT Ants are also aggressive toward each other, fighting to the death over their tree territories. The consequences for losing colonies are stark: loss of territory or colony death. After a fight, victorious colonies have to defend their newly gained territory with a workforce heavily depleted by fighting. In a new study, researchers found that victorious colonies might offset this challenge by recruiting members of the losing colonies to help.

Is Alaska's first new butterfly species in decades an ancient hybrid? Posted: 18 Mar 2016 03:16 PM PDT Some might say it takes a rare breed to survive the Alaska wilderness. The discovery of a possible new species of hybrid butterfly from the state's interior is proving that theory correct.

Key difference between mouse and human kidney cells Posted: 18 Mar 2016 03:16 PM PDT The best laid plans of mice and men are a bit different -- at least when it comes to kidney development. Compared to a mouse, a human has nearly 100 times more nephrons, the functional units of the kidneys. Humans may owe these abundant nephrons to a gene called SIX1, according to a new article.

Precision medicine's potential to define the genetics of autoimmune disease Posted: 18 Mar 2016 11:45 AM PDT Demonstrating the potential of precision medicine, an international study used next-generation DNA sequencing technology to identify more than 1,000 gene variants that affect susceptibility to systemic lupus erythematosus (SLE).
