Pilot-scale production of mcl-PHA by Pseudomonas citronellolis using acetic acid as the sole carbon source.

Medium-chain-length polyhydroxyalkanoates (mcl-PHA) are biobased materials with promising properties for environmentally friendly applications. Due to high production costs, which are related to the cost of the carbon sources combined with conversion insufficiencies, currently only small quantities are produced. This results in a lack of reliable data on properties and application potential for the variety of polymers from different types of production strains.

Cell Retention as a Viable Strategy for PHA Production from Diluted VFAs with .

The production of biodegradable and biocompatible materials such as polyhydroxyalkanoates (PHAs) from waste-derived volatile fatty acids (VFAs) is a promising approach towards implementing a circular bioeconomy. However, VFA solutions obtained via acidification of organic wastes are usually too diluted for direct use in standard batch or fed-batch processes. To overcome these constraints, this study introduces a cell recycle fed-batch system using uyuni S29 for poly(3-hydroxybutyrate) (P3HB) production from acetic acid.

Analysis of associated diseases in patients with acute critical lower limb ischemia.

Introduction: Acute critical lower limb ischemia refers to the state of severely impaired vitality of lower limbs due to acute occlusion of arterial blood vessel by a thrombus or emboli. Surgical revascularization in the first 6-12 hours after the onset of symptoms gives the best results. However, a high mortality rate and probability of limb loss make this problem more debatable, and can be related with associated diseases.

Surgical treatment of big splenic artery aneurysm--case report.

An aneurysm has been defined as a permanent local dilatation of the diameter of an artery by at least 50% of its normal value. A splenic artery aneurysm is most frequently a visceral artery aneurysm and clinically it is usually asymptomatic but potentially life-threatening at the same time, with the incidence of its rupturing being 2-10% and then the mortality rate ranges from 20 to 36%. A 51-year-old female patient was admitted to the Department of Vascular and Transplantation Surgery in Novi Sad having been found to have a big splenic artery aneurysm during the ultrasound examination of her abdomen after cholecystectomy.

[Results of autovenous femoro-distal bypass procedures in the type III peripheral obliterative arterial disease of the extremities in diabetic and nondiabetic patients].

Introduction: It has been established that infrainguinal occlusive disease, type III peripheral obliterative arterial disease (POAD), is more common in diabetics than in non-diabetics. It is presumeable that after surgical treatment of this arterial segment diabetics develop more complications and higher mortality rate than non-diabetics. The aim of this study was to analyze the results of reconstructive surgical treatment of diabetic and non-diabetic patients with type III PAOD.

[Femoro-popliteal reconstructions: "in situ" versus "reversed" technique: comparative results].

Introduction: Infrainguinal arterial reconstruction is a procedure with two main types of autologous venous grafts: reversed-vein bypass grafting, and the in situ bypass grafting. Both techniques have advantages and disadvantages, and the aim of this study was to compare the results of each technique.

Material And Methods: In the period from 1999 to 2003, 118 patients with infrainguinal arterial occlusive disease (IAOD) underwent reconstruction surgery at the Vascular and Transplantation Surgery Clinic in Novi Sad.
