Lysyl Oxidase-like 2 Dysregulation Increases the Risk of Post-Operative Fibrotic Scars Formation in the Female Reproductive Tract: A Novel Therapeutic Target to Reduce Fibrogenesis.

The formation of fibrotic bands in female reproductive system, including the uterus, after abdominal and pelvic surgeries, is an important medical challenge associated with many complications, including infertility and pain. Investigating the role of different molecules involved in fibrosis and adhesion formation may help in the development of new drugs to prevent this disorder. Lysyl oxidase-like 2 (LoxL2) is a copper-dependent enzyme that catalyzes the cross-linking of collagen and elastin fibers in the extracellular matrix (ECM) to stabilize ECM. Dysregulation of LoxL2 activity resulting from tissue hypoxia and inflammation after gynecological surgeries in the female reproductive tract increases collagen fibers cross-linking and promotes fibrosis. It has been shown that targeting LoxL2 by Lox inhibitors may reduce fibrosis. Considering the expression of LoxL2 in female reproductive organs and its dysregulation in hypoxia and inflammation, it is possible that LoxL2 has therapeutic potential as a drug target in the prevention of adhesions. In this review, we discuss the role of LoxL2 in the promotion of fibrotic processes focusing on its link with inflammatory and hypoxic conditions. We also justify the use of anti- LoxL2 agents as a potential therapeutic strategy for the prevention of post-surgical scar formation.

Medicinal plants for the treatment of neuropathic pain: A review of randomized controlled trials.

Neuropathic pain is a disabling condition caused by various diseases and can profoundly impact the quality of life. Unfortunately, current treatments often do not produce complete amelioration and can be associated with potential side effects. Recently, herbal drugs have garnered more attention as an alternative or a complementary treatment. In this article, we summarized the results of randomized clinical trials to evaluate the effects of various phytomedicines on neuropathic pain. In addition, we discussed their main bioactive components and potential mechanisms of action to provide a better view of the application of herbal drugs for treating neuropathic pain.

The circadian clock as a potential biomarker and therapeutic target in pancreatic cancer.

Pancreatic cancer (PC) has a very high mortality rate globally. Despite ongoing efforts, its prognosis has not improved significantly over the last two decades. Thus, further approaches for optimizing treatment are required. Various biological processes oscillate in a circadian rhythm and are regulated by an endogenous clock. The machinery controlling the circadian cycle is tightly coupled with the cell cycle and can interact with tumor suppressor genes/oncogenes; and can therefore potentially influence cancer progression. Understanding the detailed interactions may lead to the discovery of prognostic and diagnostic biomarkers and new potential targets for treatment. Here, we explain how the circadian system relates to the cell cycle, cancer, and tumor suppressor genes/oncogenes. Furthermore, we propose that circadian clock genes may be potential biomarkers for some cancers and review the current advances in the treatment of PC by targeting the circadian clock. Despite efforts to diagnose pancreatic cancer early, it still remains a cancer with poor prognosis and high mortality rates. While studies have shown the role of molecular clock disruption in tumor initiation, development, and therapy resistance, the role of circadian genes in pancreatic cancer pathogenesis is not yet fully understood and further studies are required to better understand the potential of circadian genes as biomarkers and therapeutic targets.

A rare case of concurrent pneumonia, rib osteomyelitis, spondylodiscitis, paravertebral and epidural abscesses in a patient with chronic granulomatous disease.

Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disorder that is characterized by deficiencies in the phagocytes capacity to eliminate ingested microorganisms, which frequently causes bacterial and fungal infections. The extensive involvement of the lungs, ribs, and vertebrae that is complicated by multiple abscesses from aspergillosis is rare. in this study, we report a 13-year-old boy with CGD who experienced concurrent pneumonia, rib osteomyelitis, spondylodiscitis, paravertebral, and epidural abscesses as a result of Aspergillus flavus infection with associated computed tomography scan and magnetic resonance imaging findings. Patients with CGD are susceptible to Aspergillus infection. Correct diagnosis based on clinical and paraclinical findings as well as choosing the best treatment regimen is essential for achieving a favorable outcome.

Soft tissue aneurysmal bone cyst in thigh muscles: A case report.

Aneurysmal bone cysts (ABCs) are benign lesions that are locally invasive. The prevalence of soft tissue ABCs is far lower than the intraosseous type. Here, we report a case of ABC in thigh muscles who presented with distal thigh pain.
