Radiotherapy of Orbital and Ocular Adnexa Lymphoma
Orbital and ocular adnexa lymphomas are rare neoplasms confined to the orbital region. The prognosis is generally favorable, with a high proportion of localized disease, indolent clinical course, prolonged disease-free intervals, and low lymphoma-related mortality rate.

Vasopressin-Related Possible Therapies in Autism
Autism spectrum disorder (ASD) is rather common, presenting with prevalent early problems in social communication and accompanied by repetitive behavior. There is no cure for ASD, and there is currently no medication to treat it. The medications are prescribed mainly to treat self-injury, inability to focus, anxiety and depression (SSRIs), aggression (alpha-2 adrenergic agonist, Clonidine) and hyperactivity (dopamine and noradrenaline stimulant methylphenidate, Ritalin). Strategies to treat the core symptoms of ASD are directed to correct synaptic dysfunctions, abnormalities in central VP, OT and serotonin neurotransmission, and neuroinflammation.

Biosimilar Agents
A biosimilar is a biological product highly similar to and interchangeable with an already approved reference product. Innovations in computer-aided discovery for biosimilar agents involve several key approaches. Structural bioinformatics and molecular docking techniques, including homology modeling and molecular dynamics simulations, aid in understanding the structure-function relationships. In silico screening and virtual high-throughput screening, powered by database mining and predictive modeling, expedite the identification of potential biosimilar candidates. Machine learning and artificial intelligence contribute by analyzing large datasets to predict success probabilities and integrating diverse data sources. Immunogenicity prediction tools assess potential immune responses, while network pharmacology and quantitative systems pharmacology provide a holistic understanding of biosimilar effects. Optimization algorithms play a role in formulating biosimilars for desired properties. This dynamic field continues to evolve, with regular updates reflecting the latest advancements in computational tools for biosimilar discovery.

Carbohydrate Counting, Mixed Meals, and Food Glycemic-Index Management
Achieving optimal glucose control in individuals with type 1 diabetes (T1DM) continues to pose a significant challenge. While continuous insulin infusion systems have shown promise as an alternative to conventional insulin therapy, there remains a crucial need for greater awareness regarding the necessary adaptations for various special circumstances. Nutritional choices play an essential role in the efficacy of diabetes management and overall health status for patients with T1DM. Factors such as effective carbohydrate counting, assessment of the macronutrient composition of meals, and comprehending the concept of the glycemic index of foods are paramount in making informed pre-meal adjustments when utilizing insulin pumps.

Mechanistic Basis for Autophagy in Diabetic Kidney Disease
Diabetic kidney disease (DKD), or diabetic nephropathy (DN), is a common but severe complication in diabetic patients. The disorder mainly consists of persistent proteinuria with progressive worsening of renal function, and can ultimately cause irreversible kidney damage. Studies have provided new insights into the connection between autophagy, a physiological metabolic process known to maintain cellular homeostasis, and the pathophysiological pathways of DKD. Typically, autophagic activity plays a role in DKD progression mainly by promoting an inflammatory response to tissue damage, while both overactivated and downregulated autophagy worsen disease outcomes in different stages of DKD.

Nitrous Oxide Abuse
The recreational use of nitrous oxide (N2O), also called laughing gas, has increased significantly in recent years. In 2022, the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) recognized it as one of the most prevalent psychoactive substances used in Europe. Chronic nitrous oxide (N2O) exposure can lead to various clinical manifestations. The most frequent symptoms are neurological (sensitive or motor disorders), but there are also other manifestations like psychiatric manifestations or cardiovascular disorders (thrombosis events). N2O also affects various neurotransmitter systems, leading to its anesthetic, analgesic, anxiolytic and antidepressant properties. N2O is very challenging to measure in biological matrices. Thus, in cases of N2O intoxication, indirect biomarkers such as vitamin B12, plasma homocysteine and plasma MMA should be explored for diagnosis and assessment.

Nonsteroidal Anti-Inflammatory Drugs in Prostate Cancer
Prostate cancer (PC) is the second most common type of cancer and the leading cause of death among men worldwide. Preventing the progression of cancer after treatments such as radical prostatectomy, radiation therapy, and hormone therapy is a major concern faced by prostate cancer patients. Inflammation, which can be caused by various factors such as infections, the microbiome, obesity and a high-fat diet, is considered to be the main cause of PC. Inflammatory cells are believed to play a crucial role in tumor progression. Therefore, nonsteroidal anti-inflammatory drugs (NSAIDs) along with their effects on the treatment of inflammation-related diseases, can prevent cancer and its progression by suppressing various inflammatory pathways. Evidence shows that nonsteroidal anti-inflammatory drugs are effective in the prevention and treatment of prostate cancer.

Mitochondrial E3 Ubiquitin Ligases in Cancer Therapy
Ubiquitination is a post-translational modification that targets specific proteins on their lysine residues. Depending on the type of ubiquitination, this modification ultimately regulates the stability or degradation of the targeted proteins. Ubiquitination is mediated by three different classes of enzymes: the E1 ubiquitin-activating enzymes, the E2 ubiquitin-conjugating enzymes and, most importantly, the E3 ubiquitin ligases. E3 ligases are responsible for the final step of the ubiquitin cascade, interacting directly with the target proteins. E3 ligases can also be involved in DNA repair, cell cycle regulation and response to stress; alteration in their levels can be involved in oncogenic transformation and cancer progression. Of all the six hundred E3 ligases of the human genome, only three of them are specific to the mitochondrion: MARCH5, RNF185 and MUL1.

Estrogen Receptor-β Isoforms and Coactivators in Breast Cancer
Nuclear receptor coregulators are the principal regulators of Estrogen Receptor (ER)-mediated transcription. ERβ, an ER subtype first identified in 1996, is associated with poor outcomes in breast cancer (BCa) subtypes, and the coexpression of the ERβ1 isoform and AIB-1 and TIF-2 coactivators in BCa-associated myofibroblasts was associated with high-grade BCa. Thus, this research aimed to identify additional coactivators that are involved in the progression of ERβ-expressing BCa. ERβ isoforms, coactivators, and prognostic markers were tested using standard immunohistochemistry. AIB-1, TIF-2, NF-kB, p-c-Jun, and/or cyclin D1 were differentially correlated with ERβ isoform expression in the BCa subtypes and subgroups
