Contemporary advances in photocatalytic CO reduction using single-atom catalysts supported on carbon-based materials.

The persistent issue of CO emissions and their subsequent impact on the Earth's atmosphere can be effectively addressed through the utilization of efficient photocatalysts. Employing a sustainable carbon cycle via photocatalysis presents a promising technology for simultaneously managing the greenhouse effect and the energy dilemma. However, the efficiency of energy conversion encounters limitations due to inadequate carrier utilization and a deficiency of reactive sites.

Modifiable cardiovascular risk factors in Rheumatoid Arthritis.

Objective: To determine the frequency of modifiable cardiovascular risk factors in Rheumatoid Arthritis patients at tertiary care hospital.

Methods: During this study 246 patients of Rheumatoid Arthritis were enrolled from outpatients department of Medicine of Central Park Medical College Hospital, Lahore from July 1, 2016 to January 31, 2017. Demographic data and questions related to study were noted.

Preparative regimen dosing for hematopoietic stem cell transplantation in patients with chronic hepatic impairment: analysis of the literature and recommendations.

Hematopoietic stem cell transplantation (HSCT) is a potentially life-saving therapy for patients with malignant and nonmalignant disease states. Transplant has been associated with high treatment-related morbidity and mortality, therefore limiting its usefulness in patients with baseline liver dysfunction. In the event that a patient with hepatic insufficiency is selected for HSCT, dosage adjustments may be considered; however, no reliable endogenous biomarkers can serve as a guide for adjustments.

Duplex ultrasound in aneurysm surveillance following endovascular aneurysm repair: a comparison with computed tomography aortography.

Objectives: Cumulative radiation dose, cost, and increased demand for computed tomography aortography (CTA) suggest that duplex ultrasonography (DU) may be an alternative to CTA-based surveillance. We compared CTA with DU during endovascular aneurysm repair (EVAR) follow-up.

Methods: Patients undergoing EVAR had clinical and radiological follow-up data entered in a prospectively maintained database.

Two-year outcome with preferential use of infrainguinal angioplasty for critical ischemia.

Objective: Infrainguinal angioplasty provides a minimally invasive alternative to bypass surgery in patients with critical ischemia. This study aimed to determine the 2-year patency, limb salvage, and survival rates in patients who underwent infrainguinal angioplasty in a unit where angioplasty is used preferentially whenever possible for critical ischemia.

Methods: A total of 333 consecutive patients who presented with rest pain, tissue loss, or both and who underwent an infrainguinal intervention in the 4-year period between January 1998 and January 2002 were divided into femoropopliteal and femorodistal groups.
