The clinical epidemiology of male osteoporosis: a review of the recent literature.

Clinical epidemiology

Willson T, Nelson SD, Newbold J, Nelson RE, LaFleur J.
PMID: 25657593
Clin Epidemiol. 2015 Jan 09;7:65-76. doi: 10.2147/CLEP.S40966. eCollection 2015.

Osteoporosis, a musculoskeletal disease characterized by decreased bone mineral density (BMD) and an increased risk of fragility fractures, is now recognized as an important public health problem in men. Osteoporotic fractures, particularly of the hip, result in significant morbidity...

Preliminary phylogenetic analysis of the Andean clade and the placement of new Colombian blueberries (Ericaceae, Vaccinieae).

PhytoKeys

Pedraza-Peñalosa P, Salinas NR, Virnig AL, Wheeler WC.
PMID: 25987883
PhytoKeys. 2015 Apr 22;(49):13-31. doi: 10.3897/phytokeys.49.8622. eCollection 2015.

The blueberry tribe Vaccinieae (Ericaceae) is particularly diverse in South America and underwent extensive radiation in Colombia where many endemics occur. Recent fieldwork in Colombia has resulted in valuable additions to the phylogeny and as well in the discovery...

Native phasing of x-ray free-electron laser data for a G protein-coupled receptor.

Science advances

Batyuk A, Galli L, Ishchenko A, Han GW, Gati C, Popov PA, Lee MY, Stauch B, White TA, Barty A, Aquila A, Hunter MS, Liang M, Boutet S, Pu M, Liu ZJ, Nelson G, James D, Li C, Zhao Y, Spence JC, Liu W, Fromme P, Katritch V, Weierstall U, Stevens RC, Cherezov V.
PMID: 27679816
Sci Adv. 2016 Sep 23;2(9):e1600292. doi: 10.1126/sciadv.1600292. eCollection 2016 Sep.

Serial femtosecond crystallography (SFX) takes advantage of extremely bright and ultrashort pulses produced by x-ray free-electron lasers (XFELs), allowing for the collection of high-resolution diffraction intensities from micrometer-sized crystals at room temperature with minimal radiation damage, using the principle...

Leading by Example: Role Modeling Resilience Helps Our Learners and Ourselves.

Academic medicine : journal of the Association of American Medical Colleges

Abaza MM, Nelson KG.
PMID: 28991841
Acad Med. 2018 Feb;93(2):157-158. doi: 10.1097/ACM.0000000000001936.

The issues of burnout and its consequences are some of the most prevalent topics in conversations about the practice of medicine today. Many reports have focused on the contributors that fuel this epidemic, but the time has come to...

THE ROLES OF FLUCTUATING SELECTION AND LONG-TERM DIAPAUSE IN MICROEVOLUTION OF DIAPAUSE TIMING IN A FRESHWATER COPEPOD.

Evolution; international journal of organic evolution

Ellner SP, Hairston NG, Kearns CM, Babaï D.
PMID: 28565171
Evolution. 1999 Feb;53(1):111-122. doi: 10.1111/j.1558-5646.1999.tb05337.x.

Direct observations of selection response in natural, unmanipulated populations in the wild are rare. Those that exist have resulted from major changes in environment during an ongoing study. Selection response should be more common and more readily observable in...

Food limitation in a wild cyclopoid copepod population: direct and indirect life history responses.

Oecologia

Hansen AM, Hairston NG.
PMID: 28308422
Oecologia. 1998 Jul;115(3):320-330. doi: 10.1007/s004420050523.

We studied the effects of food limitation on the population dynamics of the freshwater cyclopoid copepod Diacyclops thomasi in Oneida Lake, New York. In the field population, maximum juvenile abundance coincided seasonally with high phytoflagellate concentration. During the clear-water...

Management of infantile spasms.

Translational pediatrics

Nelson GR.
PMID: 26835388
Transl Pediatr. 2015 Oct;4(4):260-70. doi: 10.3978/j.issn.2224-4336.2015.09.01.

West syndrome, or infantile spasms syndrome is a frequently catastrophic infantile epileptic encephalopathy with a variety of etiologies. Despite the heterogeneous nature of causes of infantile spasms, a careful diagnostic evaluation can lead to diagnosis in many patients and...

Balancing a retroreflector to minimize rotation errors using a pendulum and quadrature interferometer.

Applied optics

Niebauer TM, Constantino A, Billson R, Hankla A, Nelson PG.
PMID: 26193025
Appl Opt. 2015 Jun 20;54(18):5750-8. doi: 10.1364/AO.54.005750.

A corner-cube retroreflector has the property that the optical path length for a reflected laser beam is insensitive to rotations about a mathematical point called its optical center (OC). This property is exploited in ballistic absolute gravity meters in...

What is the Valence of Mn in Ga(1-x)Mn(x)N?.

Physical review letters

Nelson R, Berlijn T, Moreno J, Jarrell M, Ku W.
PMID: 26588410
Phys Rev Lett. 2015 Nov 06;115(19):197203. doi: 10.1103/PhysRevLett.115.197203. Epub 2015 Nov 04.

We investigate the current debate on the Mn valence in Ga(1-x)Mn(x)N, a diluted magnetic semiconductor (DMS) with a potentially high Curie temperature. From a first-principles Wannier-function analysis, we unambiguously find the Mn valence to be close to 2+ (d(5)),...

Displacement pattern of the anterior segment using antero-posterior lingual retractor combined with a palatal plate.
