Explantation of a fully deployed coronary stent.

Percutaneous extraction of a freshly implanted stent is rarely reported, as it requires high technical expertise and accurate selection of instruments to ensure a safe retrieval process. Herein, we report a case of successful snaring of an erroneously deployed stent in the aorto-ostial position using the coaxial snare technique after successful recanalization of a complex right coronary artery chronic total occlusion. < Loss of stent position during percutaneous coronary intervention is a common occurrence especially in the aorto-ostial position of the coronary vessels.

research trends, challenges, and new-age perspectives.

L. has been one of the oldest medicinal plants cultivated for 10,000 years for several agricultural and industrial applications. However, the plant became controversial owing to some psychoactive components that have adverse effects on human health.

Influence of COVID-19 Pandemic on Cardiac Services in Bahrain: Building Cardiovascular Protocol for Future Pandemics.

Background: There are different protocols initiated to maintain the workflow in cardiovascular units around the world. Variable responses were seen in different populations. We adapted certain protocols during coronavirus disease-2019 (COVID-19) pandemic because we want to know the key element that maintains an acceptable standard of cardiovascular care during future pandemics.

Percutaneous Coronary Intervention Vs Coronary Artery Bypass Surgery for Unprotected Left Main Coronary Disease: G-LM Registry.

Coronary artery bypass surgery (CABG) has been the standard of care for revascularization for patients with obstructive unprotected left main coronary disease (ULMCA). There have been multiple randomized and registry data demonstrating the technical and clinical efficacy of PCI in certain patients with ULMCA. The purpose of this study is to evaluate clinical outcomes of ULMCA PCI as compared to CABG in patients requiring revascularization in three Gulf countries.

Is Atrial Fibrillation a Risk Factor for Worse Outcomes in Severe COVID-19 Patients: A Single Center Retrospective Cohort.

Introduction: New onset atrial fibrillation leads to worse outcomes in patients with sepsis. The association between new onset atrial fibrillation (AF) in COVID19 patients with COVID19 outcomes are lacking. This study aims to determine whether new onset atrial fibrillation in COVID19 patients admitted in the ICU is a risk factor for death or requirement of mechanical ventilation (MV).

Precision Percutaneous Coronary Intervention of a Complex Lesion.

Background: Balloon dilation and atherectomy have several limitations in the treatment of heavily calcific coronary lesions.

Introduction: Intravascular lithotripsy (IVL) is a state-of-the-art system that modifies severe calcific coronary plaques efficiently. In this paper, we report our experience with IVL in the context of a calcific in-stent chronic total occlusion.

Virus-induced gene silencing (VIGS) in L.

Background: The raised demand of cannabis as a medicinal plant in recent years led to an increased interest in understanding the biosynthetic routes of cannabis metabolites. Since there is no established protocol to generate stable gene knockouts in cannabis, the use of a virus-induced gene silencing (VIGS) method, resulting in a gene knockdown, to study gene functions is desirable.

Results: For this, a computational approach was employed to analyze the L.

Identification of Putative Precursor Genes for the Biosynthesis of Cannabinoid-Like Compound in .

The liverwort belongs to the bryophyte division of land plants and is a prospective alternate source of cannabinoid-like compounds. However, mechanistic insights into the molecular pathways directing the synthesis of these cannabinoid-like compounds have been hindered due to the lack of genetic information. This prompted us to do deep sequencing, assembly and annotation of transcriptome, which resulted in the identification and validation of the genes for cannabinoid biosynthetic pathway.

Chronic lead poisoning in an Iranian opium smoker resident in London.

A 46-year-old man of Iranian origin presented with a 4-day history of colicky abdominal pain and absolute constipation on a background of several weeks of irritability and malaise. He had smoked 10 g of opium per week for a year and a half. On examination, he had diffuse abdominal tenderness and faecal loading.

Nanomaterials in combating cancer: therapeutic applications and developments.

Unlabelled: The development of novel nanomaterials and their use in biomedicine has received much attention in recent years. Significant advances have been made in the synthesis of nanomaterials with controlled geometry, physicochemical properties, surface charge, and surface tailoring with bioactive polymers. These successful efforts have resulted in improved biocompatibility and active targeting of tumour tissues, leading to the development of a diverse range of nanomaterials that can recognize cancers, deliver anticancer drugs and destroy tumours by a variety of therapeutic techniques.

Brine shrimp lethality assay 'an effective prescreen': microwave-assisted synthesis, BSL toxicity and 3DQSAR studies-based designing, docking and antitumor evaluation of potent chalcones.

Context: In the course of searching potential antitumor agents from a library of chalcones synthesized under microwave irradiations, the brine shrimp lethality (BSL) assay and a 3D structure-activity relationship (3DQSAR) studies were followed by the antitumor evaluation of most potent analogues.

Objective: The objective of the current study was to effectively use the BSL assay for the identification of potential cytotoxic analogues from a set of compounds.

Methods: We applied the comparative molecular field analysis (CoMFA) and devised 3DQSAR on 33 synthesized chalcones leading to prediction of five related compounds with improved activity.

Chloridotris[μ(2)-2-(dimethyl-amino)-ethano-lato]-μ(3)-hydroxido-tri-μ(2)-trifluoro-acetato-tetra-copper(II) tetra-hydro-furan solvate.

The title compound, [Cu(4)(C(2)F(3)O(2))(3)(C(4)H(10)NO)(3)Cl(OH)]·C(4)H(8)O or [Cu(4)(TFA)(3)(dmae)(3)Cl(OH)]·THF (dmae is dimeth-yl-amino-ethano-late, TFA is trifluoro-acetate and THF is tetra-hydro-furan), has an approximate mol-ecular threefold symmetry with three equivalent {Cu(dmae)(TFA)} units bridging between a Cu-Cl and a hydroxide unit, with the latter two lying on the mol-ecular threefold axis. However, in the solid state, the tetranuclear complex has C(i) symmetry. The Cu atom bonded to the Cl atom has a distorted tetra-hedral geometry.

Trimetallic supported catalyst for renewable source of energy and environmental control through CO2 conversion.

A supported catalyst and a catalytic process have been developed for the conversion of carbgas (CO2 + (100 ppm) H2O + 1% H2) as a renewable source of energy and as a measure for the control of carbon dioxide -- a greenhouse gas. The carbgas was passed over a trimetallic supported catalyst consisting of ruthenium (Ru), manganese (Mn) and cobalt (Co) dispersed on a high surface area titanium dioxide support at 673 K and at atmospheric pressure with a gas space velocity of 6000-7200/h. The catalytic reaction produces methanol and propyne in a fixed bed reactor system.

Catalytic wet oxidation of phenol: the role of promoter and ceramic support.

Complete mineralization of phenol has been achieved over a cerium-manganese catalyst, doped with potassium, supported on a modified zeolite with a high surface area, under very mild conditions (110 degrees C, P(O2) = 0.5 MPa). This newly developed supported catalyst restricts the formation of bulk polymeric species on the surface, thus increasing the lifetime of the catalyst.
