The utility of Ki-67 and BrdU as proliferative markers of adult neurogenesis

adult

Boonstra R.
GSID: g27928ZTtZwJ
N Kee, S Sivalingam, R Boonstra… - Journal of neuroscience …, 2002 - Elsevier

Adult animals continue to produce new neurons in the dentate gyrus of hippocampus. Until now, the principal method of studying neurogenesis has been to inject either tritiated …

Intraoperative near-infrared fluorescence imaging of a paraganglioma using methylene blue: A case report.

International journal of surgery case reports

Tummers QR, Boonstra MC, Frangioni JV, van de Velde CJ, Vahrmeijer AL, Bonsing BA.
PMID: 25541370
Int J Surg Case Rep. 2015;6:150-3. doi: 10.1016/j.ijscr.2014.12.002. Epub 2014 Dec 05.

INTRODUCTION: Intraoperative identification of tumors can be challenging. Near-infrared (NIR) fluorescence imaging is an innovative technique that can assist in intraoperative identification of tumors, which may otherwise be undetectable.PRESENTATION OF CASE: A 19-year-old patient with symptoms, normetanephrine levels and...

A Small-Sample Choice of the Tuning Parameter in Ridge Regression.

Statistica Sinica

Boonstra PS, Mukherjee B, Taylor JM.
PMID: 26985140
Stat Sin. 2015 Jul 01;25(3):1185-1206. doi: 10.5705/ss.2013.284.

We propose new approaches for choosing the shrinkage parameter in ridge regression, a penalized likelihood method for regularizing linear regression coefficients, when the number of observations is small relative to the number of parameters. Existing methods may lead to...

A TEST OF THE CHITTY HYPOTHESIS: INHERITANCE OF LIFE-HISTORY TRAITS IN MEADOW VOLES MICROTUS PENNSYLVANICUS.

Evolution; international journal of organic evolution

Boonstra R, Boag PT.
PMID: 28563406
Evolution. 1987 Sep;41(5):929-947. doi: 10.1111/j.1558-5646.1987.tb05868.x.

The Chitty hypothesis proposes that the demographic changes occurring in microtine cycles are mediated by natural selection operating on the genetic composition of the population. Implicit in this hypothesis is the assumption that a suite of life-history traits is...

Population dynamics of the collared lemming and the tundra vole at Pearce Point, Northwest Territories, Canada.

Oecologia

Krebs CJ, Boonstra R, Kenney AJ.
PMID: 28306997
Oecologia. 1995 Sep;103(4):481-489. doi: 10.1007/BF00328687.

From 1987 to 1989 we monitored population changes during summer of the collared lemming (Dicrostonyx groenlandicus) and the tundra vole (Microtus oeconomus) at Pearce Point, Northwest Territories, Canada (69° 48' N, 122° 40' W). Populations on four study areas...

Low complication rate during intraperitoneal therapy through a totally implanted peritoneal access port in patients with ovarian cancer.

International journal of gynecological cancer : official journal of the International Gynecological Cancer Society

Nanninga AG, Willemse PH, Boonstra H, De Vries EG.
PMID: 11576244
Int J Gynecol Cancer. 1992 Mar;2(2):107-110. doi: 10.1046/j.1525-1438.1992.02020107.x.

Fifty-three patients with histologically proven ovarian cancer were treated with intraperitoneally administered cisplatin or human recombinant interferon-alpha through a totally implanted peritoneal access port. A total of 281 treatment courses were given. No complications related to surgical implantation of...

Symptomatology, localization and treatment of recurrent cervical carcinoma.

International journal of gynecological cancer : official journal of the International Gynecological Cancer Society

Tinga DJ, Bouma J, Boonstra H, Aalders JG.
PMID: 11576257

In a group of 367 women treated for invasive carcinoma of the cervix tumor recurrence was discovered at an asymptomatic stage in 16 (23%) patients. The tumor recurrence was localized to the pelvis in 29 (41%) cases, in the...

Carboplatin with cyclophosphamide in patients with advanced ovarian cancer: an efficacy and quality-adjusted survival analysis.

International journal of gynecological cancer : official journal of the International Gynecological Cancer Society

Willemse PH, De Vries EG, Kloppenburg M, Fontein DL, Aalders JG, Boonstra H, Mulder NH, Sleijfer DT.
PMID: 11576264

The efficacy and toxicity of a combination of carboplatin and cyclophosphamide (CC) were studied in a group of 76 patients with advanced ovarian cancer. Progression-free (PFS) and overall survival were compared with a historical group of 65 patients treated...

Impact of food and predation on the snowshoe hare cycle.

Science (New York, N.Y.)

Krebs CJ, Boutin S, Boonstra R, Sinclair AR, Smith JN, Dale MR, Martin K, Turkington R.
PMID: 17755536
Science. 1995 Aug 25;269(5227):1112-5. doi: 10.1126/science.269.5227.1112.

Snowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8 years in the Yukon. Two blocks of forest...

B-50/GAP-43 in neuronal development and repair.

Restorative neurology and neuroscience

Gispen WH, Boonstra J, De Graan PN, Jennekens FG, Oestreicher AB, Schotman P, Schrama LH, Verhaagen J, Margolis FL.
PMID: 21551562
Restor Neurol Neurosci. 1990 Jan 01;1(3):237-44. doi: 10.3233/RNN-1990-13410.

The protein kinase C substrate B-50 is identical to the growth-associated protein GAP-43. Although as yet no causal relationship has been established between B-50/GAP-43 and neurite outgrowth, evidence accumulates that the function of the protein relates to neuronal plasticity....
