Synthesis of sandwich type acyclic tetra-nuclear silver(I)-N-heterocyclic carbene complexes for wound healing applications.

Ayesha Riaz, Muhammad Adnan Iqbal, Haq Nawaz Bhatti, Muhammad Shahid,

Two meta-xylyl linked tetrakis-benzimidazolium salts (L1-L2) as multidentate ligands and two respective silver complexes (C1 and C2) were synthesized. A multistep reaction was done at room temperature, starting with simple benzimidazole and alkyl halides, going through precursors and salt formation by reflux and finally in situ deprotonation of tetrabenzimidazolium salts ...

Raman spectroscopy along with Principal Component Analysis for the confirmation of Silver(I)-N-heterocyclic carbene complex formation.

Saqib Ali, Ayesha Riaz, Muhammad Irfan Majeed, Muhammad Adnan Iqbal, Haq Nawaz Bhatti, Nosheen Rashid, Muhammad Kashif, Muhammad Tahir, Saira Nasir, Saifullah, Sidra Farooq, Ammara Naseem, Haq Nawaz,

In this study Raman spectroscopy is employed for the characterization of two different ligands called as S1 and S2 and their respective co-ordinate complexes called C1 and C2. Specific Raman spectral signatures are observed for each of these Silver(I)-N-heterocyclic carbene complexes Ag(I)-(NHCs), which can be associated with the imidazolium ring, ... Read more >>

Antilisterial efficacy of Lactobacillus brevis MF179529 from cow: an in vivo evidence.

Ayesha Riaz, Saleha Noureen, Iram Liqat, Muhammad Arshad, Najma Arshad,

BACKGROUND:Listeria monocytogenes is an opportunistic foodborne pathogen that causes human Listeriosis and high mortality particularly in immunocompromised individuals. Pregnant women are more prone to L. monocytogenes infection resulting in abortions. In the present study, antilisterial activity of Lactobacillus brevis (LB) MF179529, a probiotic bacterial strain, was investigated in a murine ... Read more >>

STAT6 variants and non-atopic asthma in Pakistani population.

Ayesha Riaz, Muhammad Ahsan Riaz, Luqman Khan, Muhammad Shareef Masoud, Ghulam Hussain, Muhammad Iqbal, Muhammad Qasim,

Asthma a chronic airway inflammatory disease mainly characterized by airways obstruction. Airway hyper responsiveness particularly in eosinophils and inflammatory mediators affect the bronchial mucosa. Genetic association studies show the association of single nucleotide polymorphisms (SNPs) in the STAT6 gene with asthma risk. Role of Signal transducer and activator of transcription ...

Exploring the Antioxidant Perspective of Sorghum and Millet

Imran Pasha, Ayesha Riaz, Muhammad Saeed, Muhammad Atif Randhawa,

The aim of present investigation was to determine chemical composition and antioxidant activity of sorghum and millet. Antioxidant activity was determined using 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and β‐carotene assay and total phenolic content (TPC). Individual phenolic acids were identified using high‐performance liquid chromatography. TPC ranged 0.166–0.362 mg gallic acid equivalent (GAE)/g in sorghum ... Read more >>
