The healthcare industry’s ongoing progress demands a combined approach that brings together medical knowledge, technology, and public health practices to manage diseases effectively. Current research stresses the significance of comprehensive methods, which involve utilizing technologies like virtual reality (VR) and nanotechnology in medication administration. Specifically, VR plays a vital role in improving skills and managing workloads among healthcare workers. Studies have examined several factors influencing VR systems’ efficacy, such as task difficulty, mental strain, feeling of immersion, and motion sickness – collectively known as cybersickness.

Proper design considerations are essential to maximize both user experience and educational outcomes with these tools. Furthermore, there have been developments in identifying early signs of cybersickness by analyzing users’ head movements, aiming to minimize adverse effects while increasing VR applicability within healthcare environments [1-10]. Great strides have been made in the field of nanotechnology regarding wound healing and cancer treatments, according to recent findings. Scientists have discovered that specific nanocomposites containing ceramic nanoparticles can expedite the process of wound healing due to their enhanced characteristics seen during experimental and computational assessments. Moreover, simulations show that incorporating single-walled boron nitride nanotubes into these nanocomposites strengthens their durability and functionality when subjected to increased temperatures. In another development, researchers have engineered an eco-friendly solution using copper nanoparticles embedded in nitrogen-rich carbon fiber felt for converting benzene under moderate circumstances. This novel strategy not only addresses environmental concerns but also provides health benefits given benzene’s toxic nature [11-13]. Mental health, especially among families dealing with autism, should be prioritized within public health initiatives. Studies focusing on familial psychological well-being and marriage fulfillment within autistic households provide a key understanding of the advantages associated with systematic therapy. On another note, examinations concerning how individual character attributes factor into one’s standard of living after gender confirmation surgeries reveal critical elements affecting postoperative achievements. By concentrating on these diverse aspects related to mental health, we gain substantial insight necessary to improve support mechanisms and inform future interventions [14-17]. Advancements in therapeutic techniques include the exploration of low-level laser therapy for alleviating trigeminal neuralgia symptoms, thereby offering fresh perspectives on addressing persistent discomfort. Separately, studies delving into the effect of dentin matrix proteins on self-donated guinea pig dental pulp stem cells propose possible restorative remedies. It’s equally imperative to understand the mindset of cancer patients’ associates towards chemotherapy and radiation-inflicted oral side effects; fostering awareness amongst them aims to elevate patient care levels throughout cancer therapy. Case analyses and brief narratives contribute real-world examples illustrating clinic implementations - from uncommon cases of gingival blister formation enlightening diagnostic procedures and cures to innovations like dental pulp stem cell utilization targeting pulp restoration along with bloodless plasma application combatting jawbone necrosis caused by medications. These emerging trends signal encouraging improvements in endodontics and overall clinical practice. Tooth root regrowth achievement further underscores this notion, pointing towards bright prospects ahead [18-24]. In medical research, utilizing location-scale models for comparing the efficacy of various treatments for a specific disease can be very effective. The dissertation “Model Checks for Two-Sample Location-Scale” investigates two statistical methods, ECF and PEL, for assessing patient data. These techniques allow for a more accurate determination of data distribution and help researchers compare the effectiveness of two treatments precisely, even with censored data. This approach can improve decision-making in treatments and increase the efficiency of therapeutic strategies [25]. Tortuous microvessels, commonly observed in numerous diseases, can greatly affect blood flow properties by raising apparent blood viscosity and modifying wall shear stress patterns. These alterations, driven by red blood cell dynamics, are essential for comprehending and modeling the hemodynamics of pathological states [26]. In addition to genetic diseases, there are acute and chronic non-hereditary diseases. Stroke is the second leading cause of death and illness globally and the primary cause of long-term disability. It predominantly affects individuals over 65 years old, with an estimated annual incidence rate of 7.6% [27]. Bone disorders have become increasingly prevalent worldwide, posing significant health challenges. Tissue engineering offers a promising solution by enabling the generation of fully functional bone tissues. This advanced field combines principles of biology, engineering, and materials science to develop biological substitutes that can restore, maintain, or improve bone function [28]. Hepatitis B is a significant global public health issue as it is the most common severe liver infection around the world. The disease is mainly caused by the hepatitis B virus (HBV), a small infectious agent that targets liver cells. After entering the body, HBV quickly replicates, leading to extensive damage and inflammation in the liver tissue [29]. Parkinson’s disease (PD) is one of the most prevalent neurological disorders of our time, characterized by uncontrollable movements such as shaking, muscle stiffness, and difficulty with coordination and balance. This progressive condition results from the degeneration of dopamine-producing neurons in the brain, leading to a decline in motor function and impacting the quality of life for those affected [30]. The Predictive Coding (PC) theory suggests that the brain predicts sensory input based on past experiences, focusing on discrepancies between predictions and actual input to efficiently process information. This framework explains how perceptions are formed, facilitates learning through error correction, and provides insights into various neurological and psychiatric conditions by highlighting the brain’s active role in shaping our sensory experiences and responses to the environment [31]. Besides various diseases, non- disease factors such as burns can cause serious harm, especially to the elderly, potentially leading to severe injuries or even death. These situations require prompt treatment and essential actions [32]. A serious and intricate issue for health nowadays is cancer, which involves the development of possibly harmful growths or cancerous cells. The relationship between these cells and their surroundings plays a significant role in the illness [33]. This study shows that in the microcirculation of tortuous vessels, circulating cells such as leukocytes or cancer cells can marginate to the vessel wall even in the absence of red blood cells. This behavior, known as margination, plays a significant role in physiological processes such as the migration of cancer cells to surrounding tissues and provides better insight into cell behavior in various diseases [34]. Oral cancer is a type of cancer that develops in the tissues of the mouth or throat. It belongs to a larger group of cancers called head and neck cancers and is most commonly found in individuals over the age of 40. Oral cancer can be life-threatening if not diagnosed and treated early [6, 20]. According to different cancers, prevailing therapeutic options primarily revolve around surgery and chemotherapy. Nevertheless, it is quite unfortunate that many patients still encounter instances of local reappearance and distal dissemination, ultimately resulting in grim survivorship rates - widely regarded as one of the foremost challenges confronted with this particular illness [35-42]. Substantial efforts have gone into creating and employing substances alongside multi- targeted medicines intended to act upon malignant cells, drawing inspiration from herbal commodities recognized for their wide- ranging impacts beyond synthetic alternatives’ reach. Generally speaking, these organic components tend to entail diminished production expenses coupled with minimal side effects contrasted against synthesized equivalents. For instance, curcumin - procured from turmeric root and characterized as a ketone compound - exhibits potent anti-carcinogenic and anti- inflammatory qualities supported by extensive studies. Hence, harnessing nature’s resources could pave the way for more efficient yet affordable therapeutic measures against cancer [36]. Traditional medicine has extensively employed curcumin to tackle issues like liver maladies, digestive complaints, urinary tract troubles, and rheumatoid arthritis over time. Known for its remarkable anti-inflammatory, antioxidant, and anti-cancer capacities, curcumin has captivated considerable scientific interest. Time and again, research demonstrates that curcumin instigates programmed cell death (apoptosis) and displays anti-proliferative qualities against myriad cancer cell varieties, spanning kidney, pancreas, colon rectal, breast, and prostate tumors. Consequently, curcumin emerges as a highly sought-after substance warranting intense investigation in the quest for viable cancer treatments [43-47]. Research highlights that curcumin amplifies the efficacy of certain anti-cancer pharmaceuticals in resistant cancer cells, proposing reduced chemotherapeutic dose requirements and decreased exposure to unwanted side effects. Notably, recent advances suggest that curcumin wields dual antioxidant and pro-oxidant influences, playing an instrumental role in hindering cancer growth. Beyond this, evidence substantiates that curcumin can augment the impact of additional anti-cancer agents synergistically, fortifying the search for complementary cancer treatment modalities. Thus, exploring curcumin’s unique features may unlock new avenues in devising strategic therapeutic plans [48-50].

Considering that concurrent usage of curcumin with assorted chemotherapy drugs remains unexplored in stomach cancer, this investigation seeks to scrutinize the impact of combining curcumin with established anti-cancer agents, namely paclitaxel, methotrexate, and vincristine, specifically targeting oral cancer treatment. Addressing this knowledge gap holds promise in refining therapeutic protocols and enhancing patient outcomes.

Curcumin, paclitaxel, methotrexate, and vincristine were acquired from Cell Pharma GmbH in Germany. Cholesterol, MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide), sodium pentanesulphonate, and sodium edetate were obtained from Sigma-Aldrich Corporation. Isopropanol, methanol, and chloroform were sourced from Merck. RPMI 1640 and DMEM culture media, fetal bovine serum, and penicillin/streptomycin were procured from Invitrogen Corporation. The CAL-27 cell lines were provided by the National Cell Bank of Iran at the Pasteur Institute of Iran.

The presented study grew the CAL-27 cell line in a moist atmosphere having 5% CO₂, with RPMI-1640 media enhanced by 10% FBS and penicillin/streptomycin antibiotics (100 mg/ml each) at 1 × 10⁴ cells per well in 96-well plates. Following 24 hours, the culture medium was taken out and replaced with a blend of stock solutions comprising varied concentrations of curcumin (5, 15, 30, 50 mm) derived from a 10 mg/ml curcumin (98% purity) solution in DMSO, joined with predetermined amounts of paclitaxel, methotrexate, and vincristine (300 nm, 100 mm, and 5 nm accordingly). Twenty-four hours later, the mixture was eliminated and MTT solution (0.5 mg/ml PBS in 20 μl portion) was inserted into each well for 3 hours of incubation. Later, isopropanol 100% dissolved the created formazan crystals within 10 minutes, followed by absorbance measurement at 540 nm using an ELISA reader (OrganonTeknika, Netherlands). Cell survival rate was appraised via the mentioned formula, and IC₅₀ value was estimated using the Pharm program.

In the statistical evaluation of the data, SPSS version 18 was utilized, and differences were deemed significant if the P-value was less than 0.05.

The study found that administering curcumin at 5, 15, 30, and 50 mm concentrations greatly decreased cell viability compared to the drug-free control group (Figure 1A).
