A comparative study on biologically and chemically synthesized silver nanoparticles induced Heat Shock Proteins on fresh water fish Oreochromis niloticus.

The wide applicability of silver nanoparticles in medicine and pharmaceutical industries leads to its over exploitation and thus contaminating our environment. Majority of these nanoscale dimension particles finally accumulates in fresh water and marine ecosystem. As the nanoparticles behave entirely different from its corresponding bulk material, a better understanding of their environmental impacts in aquatic ecosystems is inevitable.

Clinicopathological features and prognosis of triple negative breast cancer in Kuwait: A comparative/perspective analysis.

Aim: The aim of this study was to determine the incidence of TNBC in Kuwait, to analyze the clinicopathologic features and prognosis of this type of breast cancer, and compare it with reports from other regions of the world.

Background: Triple negative breast cancer (TNBC) is defined as a subtype that is negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2). There is a growing evidence of the heterogeneity of such entity on the molecular level that may cause discrete outcomes.

A novel method for the management of patients with heparin-induced thrombocytopaenia during cardiac surgery.

A 63-year old, male patient presented with prosthetic valve endocarditis and developed heparin-induced thrombocytopaenia (HIT) following heparin administration for continuous veno-venous haemofiltration. Use of cardiopulmonary bypass in patients suffering from heparin-induced thrombocytopaenia is difficult and challenging. We report a novel method that allows heparin use in patients diagnosed with HIT using Multiplate platelet analyser and iloprost.

Augmentation of PCR efficiency using highly thermostable gold nanoparticles synthesized from a thermophilic bacterium, Geobacillus stearothermophilus.

Biogenic gold nanoparticles were synthesized from the Geobacillus stearothermophilus cell-free extract. These nanoparticles were characterized by UV-vis spectroscopy, FTIR, TEM, and XRD. The gold nanoparticles showed an absorption maximum at 522 nm.

Inactivation of microbial infectiousness by silver nanoparticles-coated condom: a new approach to inhibit HIV- and HSV-transmitted infection.

Recent research suggests that today's condoms are only 85% effective in preventing human immunodeficiency virus (HIV) and other sexually transmitted diseases. In response, there has been a push to develop more effective ways of decreasing the spread of the disease. The new nanotechnology-based condom holds the promise of being more potent than the first-generation products.

Biosynthesis of anisotropic gold nanoparticles using Maduca longifolia extract and their potential in infrared absorption.

Metal nanoparticles, in general, and gold nanoparticles, in particular, are very attractive because of their size- and shape-dependent properties. Biosynthesis of anisotropic gold nanoparticles using aqueous extract of Madhuca longifolia and their potential as IR blockers has been demonstrated. The tyrosine residue was identified as the active functional group for gold ion reduction.

Blue orange light emission from biogenic synthesized silver nanoparticles using Trichoderma viride.

Recent advances in nanomaterial have produced a new class of fluorescence labels by conjugating noble metal with biomolecules. The nanometer size metal conjugates are water soluble, biocompatible and provide important advantage over the fluorescence dyes. In this regard we synthesized silver nanoparticles at the size of 2-4 nm using biological route and studied fluorescence property of these nanoparticles.

Fungal based synthesis of silver nanoparticles--an effect of temperature on the size of particles.

A simple and effective approach to aqueous based biosynthesis of silver nanoparticles was demonstrated and the effect of temperature on controlling size of silver nanoparticles was studied. The morphology and uniformity of silver nanoparticles were investigated by UV-Vis spectroscopy, X-ray diffraction and HrTEM. The functional group of protein molecule was identified using FTIR.

Mycobased synthesis of silver nanoparticles and their incorporation into sodium alginate films for vegetable and fruit preservation.

Biosynthesis of silver nanoparticles using Trichoderma viride and their incorporation into sodium alginate for vegetable and fruit preservation has been demonstrated in this study. Aqueous silver (Ag(+)) ions when exposed to the filtrate of T. viride are reduced in solution.

Breast magnetic resonance imaging: initial experience in Kuwait.

Objective: To report our initial experience of breast magnetic resonance imaging (MRI) in Kuwait in order to identify and characterize breast lesions.

Subjects And Methods: In 58 patients ranging in age from 25 to 64 years, breast MRI was performed as a problem-solving tool (29); for suspicious local relapse of the treated breast (6); to search for a primary breast cancer in patients with metastatic axillary lymph nodes (5); for local staging of breast cancer (5); breast implants (6); screening in high-risk patients (3), and differentiation between inflammation and inflammatory carcinoma (4). Sagittal fat-saturated T(2) and axial T(1) images were obtained before, and axial fat-saturated T(1) and dynamic sagittal fat-saturated T(1)-weighted images after contrast enhancement in a 1.

Opioid-sparing effects of diclofenac and paracetamol lead to improved outcomes after cardiac surgery.

Objective: This study assessed the analgesic efficacy, side effects, time to extubation, and oxygenation of 3 analgesic regimens after coronary artery bypass surgery using diclofenac, paracetamol, and placebo suppositories.

Design: Prospective, randomized, double-blind, placebo-controlled study.

Setting: Referral center for cardiothoracic surgery at a university hospital.
