en Breast cancer (BC) remains a major public health concerns affecting a significant number of women every year. While various therapeutic strategies exist to treat BC, but many current treatments adversely impact healthy cells, leading to considerable side effects. Further challenges in oncology include the development of the resistance of cancer cells to treatment, the limited duration of drug efficacy, and insufficient drug retention at the tumor site. This study aimed to advance diagnostic and therapeutic methodologies for cancer continues to be a critical and active field of study. One of the new and interesting technologies to treat cancers is the use of nanoparticles (NPs), which have opened a new window for the diagnosis and treatment of cancer in humans. These NPs  are used by binding to cells to carry various drugs and ligands to cancer cells, especially BC stem cells (BCSCs). This article examines recent research on the application of diverse nanosystems—including metal NPs, polymers, liposomes, and nanomicelles—for the diagnosis and treatment of BC stem cells (BCSCs). While the utilization of these nanosystems presents significant challenges and limitations, a deeper understanding of their properties holds the potential to revolutionize the management of BC. Consequently, this review explores current therapeutic strategies for BC and their associated constraints. Furthermore, it highlights NPs as a promising frontier for tumor diagnosis, imaging, and therapy, with a specific focus on the advancements involving ribonucleic acid (RNA)-loaded NPs.

en Introduction: Diabetes mellitus is a prevalent global metabolic disorder characterized by insulin resistance and pancreatic beta-cell dysfunction. Among its most severe complications are vascular disorders and the development of diabetic ulcers, particularly in the lower extremities. This study aimed to examine the effects of a combination therapy of curcumin and glycyrrhizic acid on diabetic wound healing in a murine model.  Methods: Type 2 diabetes was induced in animals by administering a high-fat diet (4900 kcal/kg) for 21 days, followed by a single intraperitoneal injection of streptozotocin (35 mg/kg). Serum glucose and insulin levels were measured using a glucometer and ELISA kit, respectively. Histopathological analysis was conducted using hematoxylin and eosin and Masson’s trichrome staining. Results: Macroscopic evaluation showed that the average wound closure rate was significantly lower in the control group compared to all treatment groups. A reduction in the wound area was observed in the groups treated with silver sulfadiazine, glycyrrhizic acid, and curcumin. Histopathological assessment indicated enhanced re-epithelialization and granulation tissue formation at the wound site in the groups treated with glycyrrhizic acid, curcumin, or silver sulfadiazine. Contrary to expectations, however, the combination of glycyrrhizic acid and curcumin did not produce synergistic effects on the regeneration rate or collagen deposition. Conclusion: Glycyrrhizic acid and curcumin accelerated diabetic wound closure in mice. This effect is mediated through modulation of the inflammatory phase and promotion of epidermal regeneration. However, the combination of the two compounds did not yield synergistic improvement in wound healing outcomes.

en The axillary artery and the variations of its branching pattern in KwaZulu-Natal populations: A cadaveric study Background: The Axillary artery (AA) is a major blood vessel located in the axilla and supplies the lateral thorax, upper limb as well as axilla through the six branches it gives off from its course. This artery exhibits variation in origin and branching patterns but its variations in laterality and sex remain underexplored, especially in the KwaZulu-Natal (KZN) population. This study aimed to document any possible anatomical variations in the origin of branches and the length of the axillary artery in the KZN population concerning sex and laterality. Materials and Methods: This study was conducted on 20 human cadavers of a white South African ethnic group (40 upper limbs), provided by the Discipline Clinical Anatomy at the University of KwaZulu Natal – Nelson R Mandela Medical School campus. Detailed dissection instructions were followed using the Grants dissector manual to carefully expose and examine the axillary artery’s variations in the origin of its branches and length. Results: It was observed that the 3rd part of AA had the most frequent number of variations of 45% in both males and females. However, females had the greatest number of variations of 54.54% on the right side in the 3rd part. There were 3 types of variations that occurred mainly in the third part. The first part had the least number of variations. The length of the axillary artery varied between sex and laterality, but females had a longer average length of 129.10 mm in this study.  Conclusion: This study reveals that the variations of AA in origin and branching patterns differ with laterality and are sexually dimorphic, a finding that could assist surgeons and radiologists in avoiding any pitfalls and complications of procedures done in the axilla.   Introduction: The axillary artery (AA) is a significant blood vessel located in the axilla that supplies the lateral thorax, upper limb, and axilla through the six branches it gives off from its course.

en Introduction: The mandibular foramen, located on the medial surface of the mandibular ramus, is a crucial anatomical landmark for delivering local anesthesia during dental procedures. Accurate localization of this foramen is critical for successful inferior alveolar nerve block administration. However, the conventional approach to this nerve block often relies on blind techniques, which are associated with a high failure rate and potential complications. This study aimed to enhance the precision of locating the mandibular foramen by evaluating two different methods to improve the effectiveness of nerve blocks. Methods: This study was conducted using a sample size of sixty-three mandibles, wherein the precise position of the mandibular foramen was analysed using two separate localization techniques: 1) the linear measurement method, which determines distances from the foramen to key anatomical landmarks, such as the mandibular notch, posterior border of the ramus, angle of the mandible, base of the mandible, and anterior border of the ramus; and 2) the triangular measurement method, which utilizes three reference points—midpoint of the anterior border of the mandibular ramus, the socket for the third molar tooth, and their distance from the mandibular foramen—to create a triangular framework for foramen localization. The efficacy of each method was assessed based on its accuracy and clinical applicability. Results: The study assessed the precise anatomical location of the mandibular foramen using two different methods. No statistically significant differences were found between the right and left sides for any measured parameters, including distances from the mandibular foramen to various anatomical landmarks. Both methods were valuable, with the first providing more comprehensive data through multiple measurements, while the second offered simplicity and ease of clinical application. Although the first method was more detailed, the second may be more practical in clinical settings.  Conclusion:  Precise localization of the mandibular foramen is essential for the effective administration of inferior alveolar nerve blocks. This study highlights the importance of adopting accurate methods for foramen identification, as doing so can significantly improve the success rate of dental anesthesia and reduce the risk of complications.  Mandibular foramen, Inferior alveolar nerve block, Dental anesthesia 31 42 http://anatomyjournal.ir/browse.php?a_code=A-10-440-1&slc_lang=en&sid=1 2024/09/252025/02/172024/03/102024/11/7 1403/8/17 2025/05/252025/04/72025/04/292025/04/6 1404/1/17 Santanu Bhattacharya Department of Anatomy, Burdwan Medical College and Hospital, PurbaBardhaman, India. dr.santanubhattacharya4@gmail.com 0031947532846007808 0031947532846007808 No Moumita Saha Department of Anatomy, Jalpaiguri Government Medical College and Hospital, Jalpaiguri, India. moumitanrsmch@gmail.com 0031947532846007809 0031947532846007809 Yes

en   Introduction: The mandible represents the predominant site of fractures within the maxillofacial complex, with its body exhibiting the highest incidence. The clinical application of the champy technique, which utilizes monocortical screws and miniplates for osteosynthesis, is complicated by the presence of accessory mental foramina (AMF), posing significant risks during interforaminal fracture management. This study aimed to quantify the risk of iatrogenic injury during interforaminal fracture fixation using the Champy technique in a South African cohort by analyzing AMF prevalence, spatial relationships, and minimum buccal bone (MBB) thickness. Methods: A morphometric analysis of 213 dry hemimandibles was conducted. AMF continuity with the mandibular canal was verified via latex injection. MBB thickness was measured at three horizontal planes (superior, foraminal, and inferior) relative to the mental foramen. Data were analyzed using IBM SPSS software, version 25. Normality was assessed via Shapiro-Wilk tests. MBB thickness comparisons across planes employed one-way analysis of variance (ANOVA) with Tukey post-hoc pairwise testing. Independent t-tests evaluated bilateral differences, while injury risks for screw lengths (4–7 mm) were calculated as a percentage of screw overlaps with vital structures relative to the total number of screw sites. G*Power software, version 3.1. was used for power analysis followed with a post hoc power analysis; mean values and standard deviations (in mm) were calculated with a 95% confidence interval (CI), while P<0.05 was considered statistically significant. Results: AMF prevalence was 6.54% (right) and 6.60% (left), with one AMF (0.93%) near a screw site. The foraminal plane had the thickest MBB (left: 6.91±2.08 mm; right: 6.69±2.04 mm) and lowest injury risk (3.44–7.55%). The inferior plane showed higher risks (up to 33.02%).  Conclusion:  The foraminal plane is the safest for miniplate placement. By tailoring the champy technique to the unique anatomical characteristics of the South African population, surgeons can enhance the safety and efficacy of interforaminal fracture fixation, ultimately reducing the risk of iatrogenic injuries.
