Minimally Invasive Approach to the Management of Recurrent Spontaneous Hemarthrosis After Total Knee Replacement: A Report of Two Cases.

Spontaneous recurrent hemarthrosis of the knee after total knee arthroplasty is an infrequent complication. Early recognition and prompt diagnosis are essential to avoid issues such as joint stiffness, chronic pain, and limited mobility. Conservative treatment methods are often effective.

Development of a MOF-5/g-CN nanocomposite: an effective type 2 heterojunction photocatalyst for rhodamine B dye degradation.

The field of environmental and water remediation faces a significant challenge in removing organic dyes from wastewater, particularly Rhodamine B (RhB), a stubborn dye used in various industries. Traditional treatment methods struggle with its resistance to decomposition, posing risks to water quality, human health, and aquatic life. This study demonstrates a novel approach to enhance photocatalytic efficiency for RhB degradation by constructing a MOF-5/g-CN composite through a facile mechanical grinding method, which is unprecedented.

Midterm functional outcomes of synthetic cartilage implant (SCI) arthroplasty for hallux rigidus.

Hallux rigidus is a common degenerative condition of first metatarso-phalangeal joint most commonly affecting patients above 50 years of age. The aim of our study is to evaluate the five-year results of synthetic cartilage implant (Cartiva) arthroplasty for hallux rigidus. A retrospective study of 70 patients who underwent synthetic cartilage implant interpositional arthroplasty were collected and analysed.

Selective synthesis of cyclic alcohols from cycloalkanes using nickel(ii) complexes of tetradentate amidate ligands.

Selective functionalisation of hydrocarbons using transition metal complexes has evoked significant research interest in industrial chemistry. However, selective oxidation of unactivated aliphatic C-H bonds is challenging because of the high bond dissociation energies. Herein, we report the synthesis, characterisation and catalytic activity of nickel(ii) complexes ([Ni(L1-L3)(OH)](ClO) (1-3)) of monoamidate tetradentate ligands [L1: 2-(bis(pyridin-2-ylmethyl)amino)--phenylacetamide, L2: 2-(bis(2-pyridin-2-ylmethyl)amino)--(naphthalen-1-yl)acetamide, L3: -benzyl-2-(bis(pyridin-2-ylmethyl)amino)acetamide] in selective oxidation of cycloalkanes using -CPBA as the oxidant.
