Dirhodium(II) Carbenes : The Chiral Product Cascade

open access: yesSultan Qaboos University Journal for Science, 2000
The last decade has witnessed enormous growth in the spectrum of highly efficient asymmetric synthetic transformations. One prominent example of this progress is the application of dirhodium (II) carbenes generated from diazo- precursors.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Synthesis of a Uniformly Spaced Array with Symmetric Amplitude Excitation by a Weighted Least-Square Method

open access: yesSultan Qaboos University Journal for Science, 2007
A new, non-iterative  technique for synthesizing equispaced linear arrays with symmetric excitation is proposed. The methods is on the computation of an  eigenvector of an appropriate real, Symmetric and positive-definite matrix.

The Basic Science of Articular Cartilage

open access: yesSports health, 2009
Articular cartilage is the highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A New record of Hydroptila cruciata Ulmer in southern Oman with notes on its Larval Biology

open access: yesSultan Qaboos University Journal for Science, 1999
Fourth and fifth instar larvae of a hydroptilid richoptcran, Hydroprtila Ulmer 1912 were collected in the Sultanate of Oman for the first time. The fifth instar larva constructs a purse-case With filamentous algae.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
