Abstract

Rhabdomyosarcoma, a malignant tumor commonly found in children and adolescents, often carries a poor prognosis. We conducted studies on the effects of the liposoluble extract of Nicotiana glauca (N. glauca), a plant from the Solanaceae family that is widely distributed, on the C2C12 murine myoblast cell line. We additionally investigated the antiproliferative effects of the extract on the RD rhabdomyosarcoma tumor cell line. The RD cells were pre-incubated without fetal bovine serum, followed by treatment with the liposoluble extract and the n-hexane sub-extract at specific concentrations. The effects on cell morphology were assessed using staining techniques. Cell viability, growth, and division capacities were evaluated through a wound assay. We analyzed the expression levels and subcellular localization of several proteins, including β-catenin, Notch 1, Caspase 3, and 14-3-3, using Western blotting. The extract of N. glauca induces apoptosis in C2C12 cells, suggesting that it may possess antitumor properties and could potentially be used in the treatment of hyperproliferative disorders. Our findings revealed that the control cells exhibited intact and normal nuclei, while the treated cells displayed characteristic morphological changes associated with apoptosis. Also, the treatments significantly reduced cell division capacity, and potentially cell migration, compared to the control group. Moreover, the evaluation of β-catenin protein localization showed a cytoplasmic and membrane proximity in C2C12 cells, whereas RD cells exhibited nuclear localization. These findings suggest the potential therapeutic value of the extract in targeting the proliferation and spread of rhabdomyosarcoma cells.

Neodymium:YAG laser posterior capsulotomy in the lateral decubitus position

Here we report a novel method of performing a Neodyminium:YAG (Nd:YAG) laser posterior capsulotomy in an adult patient, unable to tolerate the procedure awake with topical anaesthesia in the outpatient clinic setting. The procedure was performed by altering the chin rest and arms of the Nd:YAG laser machine so that the procedure could be undertaken in an anaesthetized patient in the operating theatre, in the lateral decubitus position, with the laser machine upright in its normal position.

Presbyopia correcting IOLs and the ocular surface disease… The good, the bad and the ugly

The last two decades were especially fruitful for the refractive surgeons and for the industry who have been showing tremendous development in both understanding and meeting patients’ desire for spectacle independence. Ever since the first trials from Dr. Kenneth Hoffer with his early 1980’s effort in producing a multifocal IOL to the latest achievements from different companies in putting trifocals and EDOF optics to the market.

How many mutations does it take to make a uveal melanoma?

Uveal melanoma (UM) is a rare cancer that affects the choroid and, less frequently, the ciliary body or the iris (for recent reviews see [1-3]). Despite a profound knowledge of the oncogenic mechanisms behind UM tumorigenesis and despite an accurate cytogenetic and molecular prognosis, only limited advances have been made in UM therapy.

MSICS is a Simple Solution for a Big Problem

Manual small-incision cataract surgery (MSICS) is a sutureless cataract surgery that has multiple advantages over traditional phacoemulsification and extracapsular cataract extraction (ECCE) procedures. SICS became the procedure of choice for international ophthalmology, where the microscopes and operating room can be more challenging, in addition to the more advanced pathology often seen.

Surgical smoke and SARS-CoV-2 transmission

The protection of health care workers from nosocomial infection is a paramount consideration in the current pandemic involving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Not only is prevention of viral transmission the most effective means to lessen the public health impact of coronavirus disease 2019 (COVID-19), but also both quarantine and illness – that disproportionately affect health care workers – have devastating effects on the ability of hospitals to adequately care for increased patient loads.
