RESUMO
Cancer, a multifaceted and pernicious disease, continuously challenges medicine, requiring innovative treatments. Brain cancers pose unique and daunting challenges due to the intricacies of the central nervous system and the blood-brain barrier. In this era of precision medicine, the convergence of neurology, oncology, and cutting-edge technology has given birth to a promising avenue - targeted cancer therapy. Furthermore, bioinspired microrobots have emerged as an ingenious approach to drug delivery, enabling precision and control in cancer treatment. This Keynote review explores the intricate web of neurological insights into brain-targeted cancer therapy and the paradigm-shifting world of bioinspired microrobots. It serves as a critical and comprehensive overview of these evolving fields, aiming to underscore their integration and potential for revolutionary cancer treatments.

This editorial discusses the difficulties encountered in the management of cancer among the geriatric population. Although cancer research has made substantial advancements, treatments frequently fail to consider the long-lasting consequences and adverse effects on elderly people. We advocate for enhanced geriatric oncology care, embodying enhanced evaluation techniques, the incorporation of complementary therapies, and the utilisation of wearable technologies for remote surveillance. Additionally, we suggest modifying future clinical trials to take into account the cognitive well-being of senior individuals. Implementing these modifications would greatly enhance cancer treatment for geriatric cancer patients.
RESUMO
Xanthogranulomatous inflammation is a rare benign inflammatory lesion characterized by sheets of lipid-laden foamy histiocytes. It has been reported in various organs, mainly the kidney and gall bladder. Xanthogranulomatous endometritis (XGE) is sporadic, with only a few cases reported in the English medical literature. Herein, we report a case of xanthogranulomatous endometritis with the formation of stones in a 50-year-old female patient with a prolapsed uterus. Grossly the endometrium was irregular, and the uterine cavity was filled with a yellow friable material, a polypoid growth, and yellowish stones. The microscopy showed sheets of histiocytes with few preserved endometrial glands. In this case, the xanthogranulomatous inflammation may mimic a clear cell carcinoma involving the endometrium and myometrium. One of the important differential diagnoses is malakoplakia. Immunohistochemistry and special stains are helpful in diagnosis.
RESUMO
Sleep is a fundamental process essential for reparatory and restorative mechanisms in all organisms. Recent research has linked sleep to various pathological conditions, including cancer and neurodegeneration, which are associated with various molecular changes in different cellular environments. Despite the potential significance of various molecules, the HSPA1A or Hsp70 protein, which has possible connections with sleep and different neuropsychological and pathological disorders, has been explored the least. This paper explores the potential for manipulating and discovering drugs related to the Hsp70 protein to alleviate sleep problems and improve the prognosis for various other health issues. This paper discusses the critical role of Hsp70 in cancer, neurodegeneration, apoptosis, sleep, and its regulation at the structural level through allosteric mechanisms and different substrates. The significant impact of Hsp70's connection to various conditions suggests that existing sleep medicine could be used to improve such conditions, leading to improved outcomes, minimized research costs, and a new direction for current research. Overall, this paper highlights the potential of Hsp70 protein as a key therapeutic target for developing new drugs for the treatment of sleep disorders, cancer, neurodegeneration, and other related pathological conditions. Further research into the molecular mechanisms of Hsp70 regulation and its interactions with other cellular pathways is necessary to develop targeted treatments for these conditions.Communicated by Ramaswamy H.

RESUMO
Chitin is the second most abundant biopolymer consisting of N-acetylglucosamine units and is primarily derived from the shells of marine crustaceans and the cell walls of organisms (such as bacteria, fungi, and algae). Being a biopolymer, its materialistic properties, such as biodegradability, and biocompatibility, make it a suitable choice for biomedical applications. Similarly, its deacetylated derivative, chitosan, exhibits similar biocompatibility and biodegradability properties, making it a suitable support material for biomedical applications. Furthermore, it has intrinsic material properties such as antioxidant, antibacterial, and antitumor. Population studies have projected nearly 12 million cancer patients across the globe, where most will be suffering from solid tumors. One of the shortcomings of potent anticancer drugs is finding a suitable cellular delivery material or system. Therefore, identifying new drug carriers to achieve effective anticancer therapy is becoming essential. This paper focuses on the strategies implemented using chitin and chitosan biopolymers in drug delivery for cancer treatment.

RESUMO
Glioblastoma multiforme (GBM) is a malignant primary tumor type of the central nervous system (CNS). This type of brain tumor is rare and is responsible for 12-15% of all brain tumors. The typical survival rate of GBM is only 12 to 14 months. GBM has a poor and unsatisfactory prognosis despite advances in research and therapeutic interventions via neurosurgery, radiation, and chemotherapy. The molecular heterogeneity, aggressive nature, and occurrence of drug-resistant cancer stem cells in GB restricts the therapeutic efficacy. Interestingly, the CNS tumors in children are the second most usual and persistent type of solid tumor. Since numerous research studies has shown the association between obesity and cancer, childhood obesity is one of the potential reasons behind the development of CNS tumors, including GBM. Obesity in children has almost reached epidemic rates in both developed and developing countries, harming children's physical and mental health. Obese children are more likely to face obesity as adults and develop non-communicable diseases such as diabetes and cardiovascular disease as compared to adults with normal weight. However, the actual origin and cause of obesity are difficult to be pointed out, as it is assumed to be a disorder with numerous causes such as environmental factors, lifestyle, and cultural background. In this narrative review article, we discuss the various molecular and genetic drivers of obesity that can be targeted as potential contributing factors to fight the development of GBM in children.
RESUMO
A young woman on long term corticosteroid therapy presented with a discrete hyperpigmented nodular cystic swelling on her upper thigh to the buttock region. There was history of discharging sinuses however at presentation the lesion was painless nondischarging. The lesion was subjected to fine-needle aspiration. The cytological smears on routine and special stains showed branching, septate fungal hyphae present extracellularly and intracellularly. The background showed dense mixed inflammation and granulomatous inflammation. The aspirated material was further subjected to culture. A nonsporulating melanized fungus was obtained and a culture isolate was sent for molecular characterization. Medicopsis romeroi, a rare melanized fungus belonging to the order Pleosporales was isolated on Internal transcribed spacer sequencing.
