It is necessary to clarify that temporomandibular joint disorders (TMDs) are one of the most misdiagnosed and mistreated maladies in the medical practice. It is an umbrella term, embracing conditions which involve the temporomandibular joint (TMJ) and related muscles. One of these common irritating disorders is the internal derangement which is used specifically to describe the displacement of the TMJ disc. The treatment can vary according to the severity and chronicity into non-invasive, minimally invasive, and invasive procedures. However, permanent recovery is rarely obtained.

This study was established to compare the effectiveness of two minimally invasive procedures arthrocentesis and glucocorticosteroid (GCS) local single joint injection in the management of internal derangement of the TMJ.

Thirty patients aged from 18 to 42 years were included in this study with internal derangement which was confirmed clinically and with a cone beam CT scan. The patients were divided into two groups of 15 patients. Arthrocentesis was performed to one group (group A) by using Shepard's cannula and lactated Ringer's solution. Glucocorticosteroid injection was done to the other group (group B) using a 1 ml/40 mg methylprednisolone acetate vial. The study was performed in the Department of Oral and Maxillofacial Surgery, Ghazi Alhareery Hospital-Medical City, from October 2017 to September 2018.

After 4 months of clinical follow-up, the results revealed that the GCS injection has minimal outcomes in the treatment of TMJ internal derangement compared to arthrocentesis. On the other hand, arthrocentesis and lavage had dedicated promising outcomes.

Its role in coagulation and thrombosis is well-established. Nevertheless, thrombin also plays a major role in inflammation by activating protease-activated receptors. In addition, thrombin is also involved in angiogenesis, fibrosis, and viral infections. Considering the pathogenesis of COVID-19 pandemic, thrombin inhibitors may exert multiple potential therapeutic benefits including antithrombotic, anti-inflammatory, and antiviral activities. In this review, we describe the clinical features of COVID-19, the thrombin's roles in various pathologies, and the potential of argatroban in COVID-19 patients. Argatroban is a synthetic, small molecule, direct, competitive, and selective inhibitor of thrombin. It is approved to parenterally prevent and/or treat heparin-induced thrombocytopenia in addition to other thrombotic conditions. Argatroban also possesses anti-inflammatory and antiviral activities and has a well-established pharmacokinetics profile. It also appears to lack a significant risk of drug-drug interactions with therapeutics currently being evaluated for COVID-19. Thus, argatroban presents a substantial promise in treating severe cases of COVID-19; however, this promise is yet to be established in randomized, controlled clinical trials.The eriophyoid mite Aceria massalongoi (Canestrini) was collected from globoid leaf galls on severely injured chaste trees, Vitex agnus-castus L. Compound Library price (Lamiaceae), in Bari and Bernalda (southern Italy), and on the Ionian island Leukade (Greece). Female, male and nymph were described in detail, following the current morphometric descriptive scheme, supplementing older and incomplete descriptions. Molecular characterization of A. massalongoi from Italy and Greece was conducted by amplifying and sequencing the ribosomal ITS, the D2-D3 expansion domains of the 28S rRNA gene and the mitochondrial COI, for the first time. Phylogenetic trees based on the three molecular markers showed congruent results, confirming that Italian and Greek A. massalongoi populations are the same species that cluster together with some intraspecific variability. Galls, ranging from 0.5 to 2.8 mm in diameter, were randomly distributed on both leaf surfaces, and protruded ca. 1 mm from the leaf surface. Sometimes they were closely aggregated on midrib and leaves, which, consequently, appeared strongly deformed. Close-up observations revealed that gall induction causes hyperplastic proliferation of leaf tissues around the gall chamber hosting mites. The uniserial cell lining inside this chamber provides the nutritional tissue for the mites. All feeding cells contained one or more (frequently 2-3) hypertrophied nuclei and dense granular cytoplasm.To overcome the weaknesses of traditional landfills, a modified aerobic landfill concept with intermediate covers of coarse material between waste layers functioning as facilities of drainage and aeration has been proposed recently. In this study, a one-dimensional coupled model, including aerobic biodegradation, oxygen diffusion, and advection, is proposed to describe oxygen distribution in this new type of landfill. Homotopy analysis method and perturbation method are applied to solve this model at passive aeration and active aeration, respectively. The model has six input variables, that is, oxygen diffusion coefficient, gas permeability, maximum oxygen consumption rate, layer thickness of waste, and injection pressure and extraction pressure. A combination of their typical values gives rise to over 700,000 scenarios which can be calculated by the proposed solution. The coupled effect of the above variables on oxygen migration is quantitatively investigated, followed by an estimation formula of the minimum oxygen concentration in waste layer. The maximum waste layer thickness is defined as a function of other variables for a given aeration target of oxygen volume concentration larger than 5%. A generalized design method of waste layer thickness, injection pressure, and extraction pressure is then developed for the newly proposed modified layered aerobic landfill, which can promote its popularization and application.This paper investigates the existence of the Environmental Kuznets Curve for carbon dioxide emissions in Ghana. The causal relationship between economic growth and carbon dioxide emissions being examined and the short-run and long-run parameters of the estimated vector autoregressive models are found to be unstable. This necessitated the use of a time-varying approach and the rolling window Granger causality test to investigate the causal relationship between economic growth and carbon dioxide emissions. We find that GDP has a positive effect on carbon dioxide emissions in the sample periods where GDP Granger causes carbon dioxide emissions. Significant feedbacks from the environment to the economy are observed, with carbon dioxide emissions having a positive effect on GDP in most of the subsample periods. The empirical results show that the Environmental Kuznets Curve for carbon dioxide emissions for Ghana is upward sloping, contrary to the standard Environmental Kuznets Curve theory which postulates an inverted "U"-shaped relationship between economic growth and environmental degradation.
