Zaki M, Benharref A, Daran JC, Berraho M.
PMID: 24860339
Acta Crystallogr Sect E Struct Rep Online. 2014 Apr 09;70:o526. doi: 10.1107/S1600536814007351. eCollection 2014 May 01.

The title compound, C16H24Br2O, was synthesized from the reaction of β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-heptene), which was isolated from Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol-ecules with similar conformations. Each mol-ecule is built up from two fused seven-membered...

T-helper subsets cytokine production in kidney transplant recipients: diverting influences and impact on graft outcome.

Saudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia

Hassan AA, Zaki M, Shoukeir M, Khalil R.
PMID: 18209308
Saudi J Kidney Dis Transpl. 2000 Apr-Jun;11(2):161-6.

UNLABELLED: A large body of evidence suggests the existence of functionally polarized human T-helper responses based on their profile of cytokine secretion. Human T-helper cell clones can be divided into two mutually exclusive subsets, T-helper cell 1 (Th1) and...

Relationship of associated secondary hyperparathyroidism to serum fibroblast growth factor-23 in end stage renal disease: a case-control study.

Indian journal of endocrinology and metabolism

Sliem H, Tawfik G, Moustafa F, Zaki H.
PMID: 21731867
Indian J Endocrinol Metab. 2011 Apr;15(2):105-9. doi: 10.4103/2230-8210.81939.

INTRODUCTION: Secondary hyperparathyroidism (SHPT) is an insidious disease that develops early in the course of chronic kidney disease (CKD) and increases in severity as the glomerular filtration rate deteriorates. Recent studies have identified fibroblast growth factor-23 (FGF23) as a...

Dimethylzinc-mediated alkynylation of imines.

The Journal of organic chemistry

Zani L, Alesi S, Cozzi PG, Bolm C.
PMID: 16468805
J Org Chem. 2006 Feb 17;71(4):1558-62. doi: 10.1021/jo052273o.

The treatment of various aromatic and aliphatic aldimines with a mixture of a terminal alkyne and a commercially available dimethylzinc solution in toluene yields the corresponding protected propargylic amines in moderate to excellent yields. The reaction proceeds in the...

Febrile urinary tract infection in children: Role of 99MTc-dimercaptosuccinic acid (DMSA) scan and other imaging techniques.

Annals of Saudi medicine

Zaki M, Al-Mutari G, Al-Saleh Q, Ramadan DG.
PMID: 17372481
Ann Saudi Med. 1996 Jul;16(4):410-3. doi: 10.5144/0256-4947.1996.410.

Fifty children (37 females and 13 males) with first febrile urinary tract infections were studied to assess the value of 99MTc-dimercaptosuccinic acid (DMSA) scan in detecting inflammatory changes of acute pyelonephritis (APN). These findings were compared with renal ultrasonography...

Herpes simplex virus meningitis complicated by ascending paralysis.

Proceedings (Baylor University. Medical Center)

Benjamin MM, Gummelt KL, Zaki R, Afzal A, Sloan L, Shamim S.
PMID: 23814385
Proc (Bayl Univ Med Cent). 2013 Jul;26(3):265-7. doi: 10.1080/08998280.2013.11928977.

A case of herpes simplex virus (HSV) meningitis complicated by ascending paralysis with almost complete recovery following antiviral treatment is reported. We present this case to illustrate the importance of including HSV-induced neuropathy in the differential diagnosis of acute...

The Stille Reaction: Applications in the Synthesis of Organic Dyes for DSSCs.

Chimia

Reginato G, Mordini A, Zani L, Calamante M, Dessì A, Franchi D.
PMID: 30188289
Chimia (Aarau). 2017 Sep 27;71(9):586-591. doi: 10.2533/chimia.2017.586.

The cross-coupling reaction of organic electrophiles with organostannanes, traditionally known as the Stille reaction, has found renewed interest in the preparation of new organic materials such as conjugated polymers, organic semiconductors and photoactive molecules for use in organic photovoltaics....

Late Diagnosis of Complete Colonic and Rectal Duplication in a Girl with an Anorectal Malformation.

European journal of pediatric surgery reports

AbouZeid AA, Mohammad SA, Ibrahim SE, Fagelnor A, Zaki A.
PMID: 31285983
European J Pediatr Surg Rep. 2019 Jan;7(1):e47-e50. doi: 10.1055/s-0039-1692193. Epub 2019 Jul 05.

Complete colonic duplication is rare, and usually occurs as a part of the caudal duplication syndrome. In such cases, the diagnosis is clinically evident by the presence of two ani arranged side by side in the perineum, which is...

Discovery of parabolic microresonators produced via fiber tapering.

Optics letters

Vitullo DLP, Gardosi G, Zaki S, Tokmakov KV, Brodsky M, Sumetsky M.
