Knockouts of high-ranking males have limited impact on baboon social networks

引用

current Zoology 2015年第1期61卷 107-113页

作者： Mathias FRANZ Jeanne ALTMANN susan c. ALBERTS Department of Biology Duke University Durham NC 27708-0719 USA Department of Ecology and Evolutionary Biology Princeton University Princeton NJ 08544-2016 USA

Social network structures can crucially impact complex social processes such as collective behaviour or the transmission of information and diseases. However, currently it is poorly understood how social networks change over time. Previous studies on primates suggest that ＇knockouts＇（due to death or dispersal） of high-ranking individuals might be important drivers for structural changes in animal social networks. Here we test this hypothesis using long-term data on a natural population of ba- boons, examining the effects of 29 natural knockouts of alpha or beta males on adult female social networks. We investigated whether and how knockouts affected （i） changes in grooming and association rates among adult females, and （2） changes in mean degree and global clustering coefficient in these networks. The only significant effect that we found was a decrease in mean degree in grooming networks in the first month after knockouts, but this decrease was rather small, and grooming networks re- bounded to baseline levels by the second month after knockouts. Taken together our results indicate that the removal of high-ranking males has only limited or no lasting effects on social networks of adult female baboons. This finding calls into question the hypothesis that the removal of high-ranking individuals has a destabilizing effect on social network structures in social animals [current Zoology 61 （1）： 107-113, 2015].

Stem cell Ophthalmology Treatment Study(ScOTS) for retinal and optic nerve diseases: a case report of improvement in relapsing auto-immune optic neuropathy

引用

Neural Regeneration Research 2015年第6期10卷 1507-1515页

作者： Jeffrey N.Weiss Steven Levy susan c.Benes Retina Associates of South Florida MD Stem cells Wilmer Eye Institute The Johns Hopkins Hospital

We present the results from a patient with relapsing optic neuropathy treated within the Stem cell Ophthalmology Treatment Study （ScOTS）. ScOTS is an Institutional Review Board ap- proved clinical trial and has become the largest ophthalmology stem cell study registered at the National Institutes of Health to date （*** Identifier NcT 01920867）. ScOTS utilizes autologous bone marrow-derived stem cells （BMScs） for treatment of retinal and optic nerve diseases. Pre-treatment and post-treatment comprehensive eye exams of a 54 year old female patient were performed both at the Florida Study center, USA and at The Eye center of columbus, USA. As a consequence of a relapsing optic neuritis, the patient＇s previously normal visual acuity decreased to between 20/350 and 20/400 in the right eye and to 20/70 in the left eye. Significant visual field loss developed bilaterally. The patient underwent a right eye vitrectomy with injection of BMScs into the optic nerve of the right eyeand retrobulbar, subtenon and in- travitreal injection of BMScs in the left eye. At 15 months after ScOTS treatment, the patient＇s visual acuity had improved to 20/150 in the right eye and 20/20 in the left eye. Bilateral visual fields improved markedly. Both macular thickness and fast retinal nerve fiber layer thickness were maximally improved at 3 and 6 months after ScOTS treatment. The patient also reduced her mycophenylate dose from 1,500 mg per day to 500 mg per day and required no steroid pulse therapy during the 15-month follow up.

Stem cell Ophthalmology Treatment Study (ScOTS)： bone marrow-derived stem cells in the treatment of Leber＇s hereditary optic neuropathy

Neural Regeneration Research 2016年第10期11卷 1685-1694页

作者： Jeffrey N. Weiss Steven Levy susan c. Benes Retina Associates of South Florida 5800 Colonial Drive Suite 300 Margate FL USA MD Stem cells 3 Sylvan Road South Westport CT USA The Eye center of columbus The Ohio State University Columbus OH USA

The Stem cell Ophthalmology Treatment Study （ScOTS） is currently the largest-scale stem cell ophthal- mology trial registered at *** （identifier： NcT01920867）. ScOTS utilizes autologous bone marrow-derived stem cells （BMScs） to treat optic nerve and retinal diseases. Treatment approaches include a combination of retrobulbar, subtenon, intravitreal, intra-optic nerve, subretinal, and intravenous injection of autologous BMScs according to the nature of the disease, the degree of visual loss, and any risk factors related to the treatments. Patients with Leber＇s hereditary optic neuropathy had visual acuity gains on the Early Treatment Diabetic Retinopathy Study （ETDRS） of up to 35 letters and Snellen acuity improvements from hand motion to 20/200 and from counting fingers to 20/100. Visual field improvements were noted. Macular and optic nerve head nerve fiber layer typically thickened. No serious complications were seen. The increases in visual acuity obtained in our study were encouraging and suggest that the use of autolo- gous BMScs as provided in ScOTS for ophthalmologic mitochondrial diseases including Leber＇s hereditary optic neuropathy may be a viable treatment option.

A new cGMW map released：The International Metallogenic Map of Africa at a scale of 1：5000000

引用

Episodes 2003年第2期26卷 116-118页

作者： Frost-Killian, susan Hammerbeck, Erik c.I. council of Geoscience Pretoria 0001 Private Bag X112 South Africa

The International Metallogenic Map of Africa, at a scale of 1:5 000 000 was prepared by the council for Geoscience, South Africa, under the auspices of the commission for the Geological Map of the World (cGMW) with support from UNEScO. The map was published by the cGMW and the council for Geoscience in 2002. The map supersedes an earlier version of the International Mineral Deposit Map of Africa (Sheet 1), produced in 1991. It was predominantly compiled by a team of 5 members, led by Dr. Erik Hammerbeck, Milica Veselinovic-Williams and susan Frost-Killian. Several co-authors and co-operators, including various research institutions and most of the African and Middle Eastern Geological Surveys, as well as the Bureau de Recherches Géologiques et Minières (BRGM, French Geological Survey), assisted with the compilation and verification of the mineral deposit and background geological data.

Stem cell Ophthalmology Treatment Study (ScOTS)： improvement in serpiginous choroidopathy following autologous bone marrow derived stem cell treatment

Neural Regeneration Research 2016年第9期11卷 1512-1516页

作者： Jeffrey N. Weiss susan c. Benes Steven Levy Retina Associates of South Florida 5800 Colonial Drive Suite 300 Margate FL USA The Eye center of columbus The Ohio State University Columbus OH USA MD Stem cells 3 Sylvan Road South Westport CT USA

We report results in a 77-year-old male patient with visual loss from long-standing serpiginous choroidop- athy treated with bone marrow derived stem cells （BMSc） within the Stem cell Ophthalmology Treatment Study （ScOTS）. ScOTS is an Institutional Review Board approved clinical trial and the largest ophthal- mology stem cell study registered at the National Institutes of Health to date （*** Identifier： NcT01920867）. Eight months after treatment by a combination of retrobulbar, subtenon, intravitreal and intravenous injection of BMSc, the patient＇s best corrected Snellen acuity improved from 20/80- to 20/60.1 in the right eye and from 20/50- to 20/20 3 in the left eye. The Early Treatment of Diabetic Retinopathy Study （ETDRS） visual acuity continued to improve over the succeeding 8 months and the optical coherence tomography macular volume increased. The increases in visual acuity and macular volume are encouraging and suggest that the use of BMSc as provided in ScOTS may be a viable approach to treating serpiginous choroidopathy.
