Int J Health Sci (Qassim). 2014 Apr;8(2):141-50. doi: 10.12816/0006080.

OBJECTIVE: To evaluate the knowledge of basic life support (BLS) among students and health providers in Medicine, Pharmacy, Dentistry, and Allied Health Science Colleges at Qassim University.METHODOLOGY: A cross sectional study was performed using an online BLS survey that...

Nomogram to predict prostate cancer diagnosis on primary transrectal ultrasound-guided prostate biopsy in a contemporary series.

Current urology

DiBlasio CJ, Derweesh IH, Maddox MM, Mehrazin R, Yu C, Malcolm JB, Aleman MA, Patterson AL, Wake RW, Kattan MW.
PMID: 24917732
Curr Urol. 2013 Jan;6(3):141-5. doi: 10.1159/000343528. Epub 2012 Dec 21.

OBJECTIVE: Transrectal ultrasound-guided biopsy (TRUSB) remains the mainstay for prostate cancer (CaP) diagnosis. Numerous variables have shown associations with development of CaP. We present a nomogram that predicts the probability of detecting CaP on TRUSB.METHODS: After obtaining institutional review...

Effect of the Folding of Methylene Units in the Conformational Preferences of Small Diesters.

The Journal of organic chemistry

Aleman C, Puiggalí J.
PMID: 11671687
J Org Chem. 1997 May 16;62(10):3076-3080. doi: 10.1021/jo962251p.

The conformational preferences of dimethyl succinate and ethylene glycol diacetate have been explored in the gas phase using ab initio quantum mechanical calculations at the HF/6-31G(d) and MP2/6-31G(d) levels. Furthermore, the effects of both aqueous and carbon tetrachloride solvents...

Characterization of BspA, a major boiling-stable, water-stress-responsive protein in aspen (Populus tremula).

Tree physiology

Pelah D, Shoseyov O, Altman A.
PMID: 14966001
Tree Physiol. 1995 Oct;15(10):673-8. doi: 10.1093/treephys/15.10.673.

We identified a novel 66 kDa boiling-stable protein (BspA) in cultured shoots of aspen (Populus tremula L.) which was highly expressed in response to gradual water stress. The BspA protein, which was highly expressed as early as 1 h...

Chlorophyll catabolism in senescing plant tissues: In vivo breakdown intermediates suggest different degradative pathways for Citrus fruit and parsley leaves.

Proceedings of the National Academy of Sciences of the United States of America

Amir-Shapira D, Goldschmidt EE, Altman A.
PMID: 16593821
Proc Natl Acad Sci U S A. 1987 Apr;84(7):1901-5. doi: 10.1073/pnas.84.7.1901.

High-pressure liquid chromatography was used to separate chlorophyll derivatives in acetone extracts from senescing Citrus fruit peel, autumnal Melia azedarach L. leaves, and dark-held detached parsley (Petroselinum sativum L.) leaves. Chlorophyllide a and another polar, dephytylated derivative accumulated in...

Conformational features of an actuator containing calix[4]arene and thiophene: a molecular dynamics study.

The journal of physical chemistry. B

PMID: 16706442
J Phys Chem B. 2006 May 25;110(20):9876-81. doi: 10.1021/jp060680d.

Molecular dynamics simulations have been performed for poly(calix[4]arene bis(bithiophene)) in dichloromethane solution. This material responds to its electronic structure variations with significant conformational changes, producing contraction-expansion movements. Simulations have been performed for the three states of this molecular actuator...

Giladi I, Altman A, Goren R.
PMID: 16660013
Plant Physiol. 1977 Jun;59(6):1161-4. doi: 10.1104/pp.59.6.1161.

The omission of sucrose from the basal medium stimulated callus formation in bud explants of Citrus sinensis (L.) Osbeck. Moreover, it increased the abscisic acid-induced callus proliferation reported earlier in the presence of 5% sucrose (Altman and Goren, Physiol....
