The tradition of khat chewing has been deep-rooted in the African and Arabian Peninsula for centuries. Due to its amphetamine-like psycho-stimulant or euphoric effect, Khat has been used by millions in Somalia, Ethiopia, Saudi Arabia and Yemen. The long-term use of Khat can induce tremendous health outcomes, which may be serious and irreversible.

Prolong use of Khat constituents has been associated with different types of cancers such as prostatic, breast and ovarian cancer. However, it has been very difficult to identify the molecular targets involved in Khat carcinogenesis that interact with the Khat constituents by in vitro/in vivo experimental tools.

In silico tools to predict potential targets involved in the carcinogenesis of Khat. Pass on-line prediction server was used for the prediction of a potential molecular target for Khat constituents. Molecular Dynamics simulation and MMGBSA calculation of the predicted target.

Molecular Dynamics simulation and MM-GBSA calculation. Results revealed that extensively all over the world. DDD86481 research buy The present study provides deep insight to understand the effect of Khat constituents involve in the impairment of reproductive system and its binding to 17β-HSD5. ADMET profiling also suggested that few Khat constituents do not fulfill the requirements of Lipinski rule of five i.e. poor absorption and blood-brain barrier impermeability.

High-frequency ultrasound (HFUS) is a mobile, radiation-free imaging tool for the diagnosis of musculoskeletal disorders. We aim to demonstrate the diagnostic value of dynamic HFUS for undiagnosed lower chest, upper abdomen, and loin pain with this case series.

A cricketer presented with long-standing left-sided dull ache lower chest and upper abdominal pain, aggravated on exertion and leaning forward. His previous laboratory and previous imaging tests were unrevealing. Dynamic HFUS of his left ribs during hooking maneuver demonstrated slipping of the eighth rib over the seventh rib associated with clicking. He also reported tenderness over this region. He was diagnosed as slipping rib syndrome (SRS), and was treated with the eighth nerve block under the HFUS guidance. The second and third cases presented with chronic undiagnosed waxing and waning loin pain despite extensive laboratory and radiological workup. Both patients demonstrated twelfth rib HFUS probe tenderness in sitting position with a specific movement that reproduced the pain during dynamic HFUS study. The diagnosis of twelfth rib syndrome (TRS) was confirmed, and treated successfully with a local intercostal nerve block.

HFUS is the most underutilized imaging tool for the diagnosis of unexplained upper abdominal and lower chest pain syndromes. We identified only a few such reported cases managed with the help of HFUS.

The dynamic HFUS is a valuable imaging modality for the undiagnosed lower chest, upper abdominal, or loin pain.

Particularly, coronaviruses are mentioned among the viruses implicated in autoimmunity. Today, the world's greatest threat derives from the pandemic of a new human coronavirus, called "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2), the responsible agent of coronavirus disease 2019 (COVID-19). COVID-19 originated in Wuhan, the capital of Hubei, China in December 2019 and, to date, has spread to at least 187 countries. This review focuses on autoimmune manifestations described during COVID-19, including pro-thrombothic state associated to antiphospholipid antibodies (aPL), acute interstitial pneumonia, macrophage activation syndrome, lymphocytopenia, systemic vasculitis, and autoimmune skin lesions. This offers the opportunity to highlight the pathogenetic mechanisms common to COVID19 and several autoimmune diseases, in order to identify new therapeutic targets. In a supposed preliminary pathogenetic model, SARS-CoV-2 plays a direct role in triggering widespread microthrombosis and microvascular inflammation, because it is able to induce transient aPL, endothelial damage and complement activation at the same time. Hence, endothelium might represent the common pathway in which autoimmunity and infection converge. In addition, autoimmune phenomena in COVID-19 can be explained by regulatory T cells impairment and cytokines cascade.The article has been withdrawn at the request of the authors and editor of the journal Current Organic Synthesis.
