Cobalt oxide nanoparticles induce cytotoxicity and excessive ROS mediated mitochondrial dysfunction and p53-independent apoptosis in melanoma cells.

Nanotherapy has emerged as a promising strategy for the targeted and efficient treatment of melanoma, the most aggressive and lethal form of skin cancer, with minimized systemic toxicity. However, the therapeutic efficacy of cobalt oxide nanoparticles (CoONPs) in melanoma treatment remains unexplored. This study aimed to assess the therapeutic potential of CoONPs in melanoma treatment by evaluating their impact on cell viability, genomic DNA and mitochondrial integrity, reactive oxygen species (ROS) generation and apoptosis induction in melanoma A-375 cells.

Comparative study between fractional laser assisted drug delivery of botulinum toxin versus botulinum toxin injection in primary palmar and axillary hyperhidrosis.

Palmar hyperhidrosis is common condition that is challenging to treat. Nonsurgical treatments include topical antiperspirants, iontophoresis, anticholinergic drugs and botulinum toxin injections. To evaluate the safety and efficacy of ablative fractional laser therapy, combined with topically applied botulinum toxin versus its injection for the treatment of hyperhidrosis.

Assessment of serum soluble transferrin receptor in adult Egyptian aplastic anemia patients.

Aplastic Anemia (AA) is one of the life-threatening bone marrow failure syndromes. One of the main pathologies of AA is reduced erythropoietic activity evidenced by decreased soluble transferrin receptor (sTfR) levels which results in minimal iron utilization and accumulation of iron in tissues in the form of ferritin. This study aimed to measure serum level of sTfR in adult AA patients and correlate it with the severity of the disease and the response to treatment.

Using flow-cytometry in measuring platelet activity in type 2 diabetes and predicting macrovascular complications.

Platelets are hyperactive in patients with type2 diabetes (T2DM), they adhere to vascular endothelium and play a key role in macrovascular complications. Platelets activity can be measured by flow-cytometry (cluster of differentiation (CD) 41, CD 42, CD 62, CD 63), which allows detection of surface antigens in a sensitive and specific manner. This study aimed to describe platelets activity in T2DM in association with cardiovascular and cerebrovascular complications in relation to duration of diabetes (DM).

An epidemiological risk assessment of imported malaria cases and potential local transmission in Qatar.

Preventing local transmission of malaria from imported cases is crucial for achieving and maintaining malaria elimination. This study aimed to investigate the epidemiological characteristics of imported malaria cases and assess the distribution of malaria vectors in Qatar. Data from January 2016 to December 2022 on imported malaria, including demographic and epidemiological characteristics, travel-related information, and diagnostic results, were collected and analysed using descriptive statistics.
