Ecological footprint-technological innovations nexus: new empirical evidence from panel data estimations.

The aim of this approach is to establish a relation between ecological footprint and technological innovations by using panel data techniques and taking Union for the Mediterranean member countries as the case. On the one hand, the Mediterranean region is an alarming region when it comes to environmental degradation; on the other hand, existing intergovernmental organizations such as the Union for the Mediterranean may provide a sound ground to take common action among all members against such a degradation. The approach takes eleven member countries from the Union for the Mediterranean (Bosnia and Herzegovina, France, Greece, Israel, Italy, Jordan, Morocco, Portugal, Spain, Tunisia, Türkiye) and observes them for the time frame 1992-2020.

Design, manufacture, and fatigue analysis of lightweight hip implants.

Background: This study aims to design, analyze and manufacture lightweight hip implants which have sufficient fatigue performance to enable use in total hip arthroplasty (THA).

Methods: The lattice structure was applied on an implant geometry, which is frequently used in THA, to provide a reduction in mass and increase flexibility. The implant surfaces were roughened using semispherical pores to improve the osseointegration.

Monitoring the osseointegration process in porous Ti6Al4V implants produced by additive manufacturing: an experimental study in sheep.

Background: This study investigated the design and osseointegration process of transitive porous implants that can be used in humans and all trabecular and compact bone structure animals. The aim was to find a way of forming a strong and durable tissue bond on the bone-implant interface.

Methods: Massive and transitive porous implants were produced on a direct metal laser sintering machine, surgically implanted into the skulls of sheep and kept in place for 12 weeks.

Association of genetic polymorphisms with endothelial dysfunction in chronic heart failure.

Objectives: Endothelial dysfunction can be shown very early in the cardiovascular disease. In the present study the association between congestive heart failure (CHF), endothelial function and 3 gene polymorphisms was investigated.

Patients And Methods: In 104 healthy controls and 104 CHF patients, endothelial constitutive nitric oxide synthase (ecNOS), angiotensin converting enzyme (ACE) and angiotensin II type 1 receptor (AT1R) gene polymorphisms were assessed.

Endothelial constitutive nitric oxide synthase, angiotensin converting enzyme, angiotensin II type 1 receptor gene polymorphisms and endothelial functions in healthy individuals.

Introduction: Endothelial dysfunction is recognized as an early and initiating event in the pathogenesis of coronary artery disease. Gene polymorphisms of endothelial constitutive nitric oxide synthase (ecNOS), angiotensin converting enzyme (ACE) and angiotensin II type 1 receptor (AT1R) have been found to be associated with atherosclerosis.  We aimed to investigate the possible effects of ecNOS, ACE and AT1R gene polymorphisms on endothelial functions in healthy population.
