PuCl{CoCp[OP(OEt)]}: transuranic elements entering the field of heterometallic molecular chemistry.

Recent advances enabled the discovery of heterometallic molecules for many metals: main group, d-block, lanthanides, and some actinides (U, Th). These complexes have at least two different metals joined by bridging ligands or by direct metal-metal bonding interactions. They are attractive because they can enable chemical cooperativity between metals from different parts of the periodic table.

A combined inorganic-organic titanium-44/scandium-44g radiochemical generator.

Scandium-44g (t = 4.0 h) is an emerging radioisotope for positron emission tomography. It can be produced with a radiochemical generator using its long-lived parent, titanium-44 (t = 59.

[Total Replacement of the First Metatarsophalangeal Joint by Medin PH-Flex and Its Effect on Forefoot Biomechanics in the Propulsion Phase of the Gait Cycle].

PURPOSE OF THE STUDY Total arthroplasty of the first metatarsophalangeal joint is one of the surgical treatment options for patients with advanced hallux rigidus. This study evaluates the pressure changes in the propulsion phase of the gait cycle using dynamic pedobarography after the total arthroplasty of the first metatarsophalangeal joint by Medin PH-Flex and their comparison with the control groups of patients with hallux rigidus and with asymptomatic patients. MATERIAL AND METHODS Dynamic pedobarograph was used to evaluate 15 first MTP joint replacements by Medin PH-Flex implants in 12 female patients, the average time since joint replacement was 3.

[Bacteremic purulent knee arthritis caused by a non-toxigenic strain of Corynebacterium diphtheriae].

Corynebacteria, non-spore-forming, gram-positive, aerobic or facultative anaerobic, pleomorphic bacilli, are part of the normal skin, oropharyngeal, and intestinal flora in humans. However, this microorganism can rarely be associated with invasive infections such as bone and joint infections, bacteremia, endocarditis, meningitis, liver and spleen abscesses. We present a case of bacteremic arthritis of a native knee joint caused by non-toxigenic Corynebacterium diphtheriae in a patient with alcoholic liver cirrhosis.

Non-enzymatic electrochemical determination of cholesterol in dairy products on boron-doped diamond electrode.

Determination of cholesterol in food matrices is essential for quality control concerning the health of consumers. Herein, a simple electrochemical approach for cholesterol quantitation in dairy products is evaluated. The newly developed differential pulse voltammetric method using acetonitrile-perchloric acid mixture as a supporting electrolyte is statistically compared to GC-MS and HPLC-UV.

[Native Joint Septic Arthritis in Adults: Incidence in Our Group of Patients and Antibiotic Therapy Guidelines].

PURPOSE OF THE STUDY The purpose of the study is to analyse the number of adult patients treated in our department for native joint septic arthritis and to outline guidelines for antibiotic therapy. MATERIAL AND METHODS From the beginning of 2003 to the end of 2020, a total of 36,342 surgeries were performed at our department. We retrospectively reviewed and analysed all surgeries for native joint septic arthritis (a total of 538 surgical interventions).

[Minimally Invasive Hallux Valgus Surgery: First Experience].

PURPOSE OF THE STUDY The Minimally Invasive Chevron Akin (MICA) is a percutaneous technique used to correct hallux valgus deformity. The combination of distal osteotomy of the first metatarsal and the proximal phalanx of the big toe stabilized with internal fixation was used over the last decade. The retrospective study presents the results of measurements performed on preoperative and postoperative X-rays and offers a comparison with conventional osteotomies.

Voltammetry of 7-dehydrocholesterol as a new and useful tool for Smith-Lemli-Opitz syndrome diagnosis.

7-Dehydrocholesterol is an essential biomarker of Smith-Lemli-Opitz syndrome, a congenital autosomal recessive disorder. This study shows for the first time that electrochemical oxidation of 7-dehydrocholesterol can be used for its voltammetric determination. Two classes of supporting electrolytes in acetonitrile and a mixture of acetonitrile-water were used: inorganic acids known to promote structural changes of steroids and indifferent electrolytes.

[Outcomes of Revisions of the Acetabular Component of THA with Paprosky Type 3a and 3b Defects Using Tantalum Trabecular Metal Implants 2-10 Years Postoperatively].

PURPOSE OF THE STUDY Tantallum trabecular metal implants (Trabecular Metal Technology - TMT) considerably changed the acetabular reconstruction options in revision surgeries with extensive bone defects and distorted pelvic ring integrity. The purpose of this study is to ascertain the short-term to medium-term outcomes of acetabular reconstruction through TMT implants in patients with Paprosky type 3a and 3b acetabular defects and in case of pelvic discontinuity. MATERIAL AND METHODS The prospective monocentric study included patients in whom the revision of acetabular components in total hip arthroplasty was performed, the acetabular defect was classified as Paprosky 3a and higher, a TMT implant was used for reconstruction, and the follow-up period was at least 2 years after surgery.

A novel voltammetric approach to the detection of primary bile acids in serum samples.

An innovative voltammetric approach to the detection of cholic and chenodeoxycholic acids is presented. These two primary bile acids are important biomarkers of liver function in humans and are involved in many physiological processes in the human body. Herein we describe a way to reproducibly convert the hard-to-detect bile acid molecule into an easily detectable derivative in situ using 0.

The change of first metatarsal head articular surface position after Lapidus arthrodesis.

Background: The Lapidus procedure has been used for hallux valgus deformity correction since 1931. In some cases, the arthrodesis results in an unfavourable lateral inclination of first metatarsal head articular surface. The objective of our study was to evaluate the change of orientation of this articular surface in relation to the second metatarsal axis by comparing pre- and postoperative radiographs.

[Our Experience with the Total Replacement of the First Metatarsophalangeal Joint by Medin PH-flex].

The first metatarsophalangeal (MTP) joint replacement ranks among the treatment methods of patients with hallux rigidus. The paper aims to evaluate the short-term to mid-term outcomes and to present clinical experience with our Medin PH-flex implant. MATERIAL AND METHODS In the period from January 2011 to 2016 we performed total replacement of the first MTP joint in 31 patients, in 4 cases bilaterally.

Twinned Growth of Metal-Free, Triazine-Based Photocatalyst Films as Mixed-Dimensional (2D/3D) van der Waals Heterostructures.

Design and synthesis of ordered, metal-free layered materials is intrinsically difficult due to the limitations of vapor deposition processes that are used in their making. Mixed-dimensional (2D/3D) metal-free van der Waals (vdW) heterostructures based on triazine (C N ) linkers grow as large area, transparent yellow-orange membranes on copper surfaces from solution. The membranes have an indirect band gap (E = 1.

Non-Enzymatic Electrochemistry in Characterization and Analysis of Steroid Compounds.

This review summarizes achievements in electrochemistry-related research of steroid-based compounds in clinical, pharmaceutical, and environmental analysis. Special attention is paid to compounds possessing none or only isolated double bonds at the steroid core. Their direct redox activity is limited to far positive/negative potentials under variety of conditions and electrode materials and relies on the functional groups attached to the steroid skeleton, or as the case may be its double bond or moieties present at the side chain.
