Reactive oxygen species (ROS) are essential for cancer signalling pathways and tumour maintenance, making ROS targeting a promising anti-cancer strategy. Coenzyme Q (CoQ10) has been shown to be effective against various cancers, but its impact on retinoblastoma, alone or with trolox, remains unreported. Cytotoxicity of CoQ alone and with trolox was evaluated in normal human retinal pigment epithelium cells (ARPE-19) and Y79 retinoblastoma cells using CCK-8.

The association is defined as two or more malformations with unclear relationships, which do not fit the criteria of a syndrome. This case report presents a rare finding of tubular colonic duplication in association with Mayer-Rokitansky-Küster-Hauser syndrome in an adolescent girl. The patient presented with gastrointestinal bleeding and abdominal pain, necessitating surgical intervention.

The process of drug resistance is influenced by a number of important variables, including MDR genes, drug efflux, low-quality medications, inadequate dosage, etc. Drug resistance must be addressed, and new combinations based on the pharmacokinetics/pharmacodynamics (PK-PD) characteristics of the partner pharmaceuticals must be developed in order to extend the half-lives of already available medications.

At times, mounting a strong immune response against tumour cells may not spare normal cells, leading to a variety of multisystemic adverse effects. With this, we present a case of a 64-year-old male who developed acute pancreatitis after completing eight cycles of Keytruda for castrate-resistant metastatic prostate cancer for six months, after all other causes of pancreatitis were excluded.

It results from maternal immunizations against fetal platelet antigens. Here, we report a case of a pregnant patient at 30 weeks gestation who presented to the hospital with a low platelet count of 90 th/mm and was found to have anti-human platelet antigen (HPA) 1a, 2b antibodies.

Previously, studies have demonstrated the neuroprotective abilities of antioxidants like coenzyme Q (CoQ) and vitamin E analogs like α-tocopherol against neuropathies resulting from NMDA insult, but have failed to shed light on the effect of CoQ and trolox, a hydrophilic analog of vitamin E, on glaucomatous neurodegeneration. In the current study, we wanted to investigate whether the combined effect of trolox with CoQ could alleviate NMDA-induced death of retinal cells while also trying to elucidate the underlying mechanism in relation to the yet unexplained role of vascular endothelial growth factor (VEGF) in NMDA-mediated excitotoxicity.

JAK2/STAT3 pathway can be an important lead in anticancer drug discovery, as restraining the downstream signalling of this pathway results in the induction of cell apoptosis. Moreover, various limitations associated with chemotherapy are the reason to find an alternative herbal-based therapy.

Despite high demand for the vaccines in Nepal, the country still contends with challenges related to vaccine accessibility, equitable vaccine distribution, and vaccine hesitancy. Study objectives were to identify: 1) up-take and intention for use of COVID-19 vaccines, 2) factors associated with vaccine up-take, and 3) trusted communication strategies about COVID-19 and the vaccines.

Background: SARS-CoV-2 has emerged as a major pandemic of the century and little is known about the impact of maternal infection on placental histopathology. Histopathologic examination of placental tissue can contribute to significant information regarding the pathophysiology of the disease and how it affects the fetal outcome.
Materials And Methods: This was a cross-sectional study conducted at the Department of Pathology, Government Doon Medical College and Hospital, Dehradun, on the placenta of 50 coronavirus disease 2019 (COVID-19)-positive pregnant females confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) from August 2020 to October 2020.

Angiotensin-converting enzyme 2 (ACE-2), a human receptor that facilitates entry of SARS-CoV-2, serves as a prominent target for drug discovery. In the present study, we have applied the bioinformatics approach for screening of a series of bioactive chemical compounds from Himalayan stinging nettle (Urtica dioica) as potent inhibitors of ACE-2 receptor (PDB ID: 1R4L).

Macrophage Activation Syndrome (MAS) is a potentially fatal inflammatory condition that can rapidly lead to multi-organ failure if inadequately treated. Also, known as secondary Hemophagocytic Lymphohistiocytosis (sHLH), MAS is commonly seen as a complication of systemic inflammatory disorders, like systemic juvenile idiopathic arthritis (sJIA) and systemic lupus erythematosus (SLE). However, MAS can also present as a complication of malignancies and infections, particularly viral infections like Epstein-Barr virus (EBV), cytomegalovirus (CMV) and HIV.
