One of the options for reconstructive surgery is local muscle rotational flaps by the flexor carpi ulnaris (FCU) and brachioradialis (BR). This study aimed to explore the morphometry and vascular anatomy of FCU and BR. Thirty formalin-embalmed cadaveric upper extremities (16 right and 14 left) were utilized for this study. The average length of the FCU muscle belly was 28.96 ±2.16 cm within a range of 24.3 to 32.5 cm, and the average length of the tendon was 10.05 ± 2.2 cm, with a range of 6.9 to 14.3 cm. The number of vascular pedicles for FCU was one in 5, two in 21, and three and four in 2 specimens respectively. All the pedicles arose from the ulnar artery. The average length of the BR muscle was 28.2 ±3.58 cm, with a range of 22.8 to 36.8 cm, and the average length of its tendon was 8.2 cm, with a range of 5.7 to 13.5 cm. In 90% of specimens, BR had only one vascular pedicle and in 10% there were two pedicles. These pedicles arose from the radial recurrent artery and the radial artery. Detailed morphometric and topographic anatomy of the vascular pedicles of FCU and BR are provided in this study, which can be considered the morphological database for the South Indian population.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141039235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of our study is to analyse the main anatomical bone and neurovascular structures of the middle cranial fossa by means of a transpalpebral transorbital lateral endoscopic approach (TTLEA). An anatomical study was performed on 12 orbital cavities corresponding to 6 cadaver heads. All specimens were previously injected with colored latex through both carotid systems. The mean distance from the orbital rim to the zygomatic-facial foramen and to the zygomatic-temporal foramen was 11 mm and 16 mm respectively. In all cases the meningo-orbital foramen was found at a mean distance from the orbital rim of 34 mm. The superior orbital fissure (SOF) was located posterior to the meningo-orbital foramen at 39 mm. The foramen rotundum and foramen ovale were located separated from each other by 10 mm on average. Anterior to the foramen ovale a bony prominence was observed in all cases. In 11 cases (92%) the entrance of the accessory meningeal artery into the foramen ovale was evident and in one case an accessory foramen was observed. The middle meningeal artery was located in all dissections within the foramen spinosum. The TTLEA offers a wide and direct exposure of the middle cranial fossa. It should be considered as an alternative to transcranial approaches in certain lesions invading the lateral region of the middle cranial fossa, the lateral wall of the cavernous sinus or the infratemporal fossa.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141030318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Any alteration in the developmental process could largely influence the organogenesis, thus predisposing to several adulthood diseases. Leptin is a pleiotropic gene secreted by adipose cells. However, the purview of its actions is much beyond merely the extent of human adipose reserve. It regulates several cellular mechanisms such as cell proliferation, inflammation, vasculogenesis, and the production of collagen fibres. Further leptins are thought to play a putative role in embryogenesis and tumorigenesis. The aim of thIS study was to investigate the localization of the protein in fetal and cancer kidney in an attempt to understand the role of the protein in fetal kidney development and in renal cancer. Leptin expression was evaluated by subjecting tissue sections from paraffin-embedded blocks of renal tissues (fetal, adult and cancer) to immunohistochemistry staining. The tissues were scored based on the staining pattern and percentage of immunoreactive cells. The tissues were subjected to haematoxylin and eosin stain before performing immunohistochemistry. The images were analyzed and photographed. Mild staining for leptin was observed in the tubules of fetal and adult kidneys. Mild to moderate staining was seen in membranes of renal cell carcinoma tissues. It appears such that leptin may not be a key factor or rather a temporary factor in the developmental process of the kidney. The low levels of leptin in normal adult renal tissues may be physiologically significant. The role of leptin in the renal cell carcinoma progression is sceptible.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141030462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of Onodi cells may increase the risk of optic nerve injury and result in confusion with sphenoid sinuses during endoscopic sinus surgery, leading to the oversight of sphenoid sinus pathology. The aim of the study was to examine the characteristics of Onodi cells and their relationship with the optic nerve on CT scans. A cross-sectional study was conducted, analyzing CT scans of paranasal sinuses in 196 posterior ethmoid air cells from 98 patients (30 males and 68 females) aged 18 or older, without abnormalities in the paranasal sinuses and optic nerve anatomy. The prevalence of Onodi cells was 38.78%, with 26.32% on the left, 44.74% on the right, and 28.94% bilaterally. Onodi cell pneumatization was observed in the order of Type I > Type II > Type III on both sides. The most common relationship between Onodi cells and the optic nerve was Type A on both sides. The incidence of the optic nerve bulging into Onodi cells was 50%, and the exposure of the optic nerve into Onodi cells was 7.89%. The study investigated the prevalence and relationship between Onodi cells and the optic nerve.

It serves as a protective passageway for the vertebral artery and vertebral vein, supplying blood to the brain and spinal cord. Any compromise to these structures within the foramen can lead to severe neurological complications, emphasizing its clinical significance. The study was carried out on 83 subjects of typical cervical vertebrae. Among them were 42 males and 41 females. All the foramen transversaria were observed for any anatomical variations. The anteroposterior, transverse diameters of all the foramen transversaria and the distance between the medial margin of uncinate process to the foramen transversarium were measured. The average transverse diameter of typical cervical vertebrae and seventh cervical vertebrae were ± 0.84mm and 5.13 ± 1.22 mm respectively. The average anteroposterior diameters of typical and seventh cervical vertebrae were 4.84 ± 0.69 mm and 3.91 ± 1.17 mm respectively. The distance from medial border of uncinate process to foramen transversaria was 4.28 ± 0.77 mm in typical and 5.44 ± 1.28 mm in seventh cervical vertebrae. The incidence of double bubble foramen in typical cervical vertebrae was reported to be17.5%. The incidence of double foramen transversaria was 12.5% in the seventh cervical vertebrae. Osteophytes were obstructing the foramen transversarium and narrowing it in 25% of vertebrae. In cone beam computed tomography (CBCT), the foramen transversarium plays a pivotal role in precise imaging of the cervical spine. Its significance lies in providing clear visualization of anatomical structures and potential abnormalities, aiding in the accurate diagnosis and treatment planning for various spinal conditions, thus enhancing patient care.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141023024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medicinal plants or their derivatives generally exhibit gastroprotective effect by promoting the protective factors against the aggressive factors of the gastric mucosa. The study was conducted to elucidate the gastroprotective mechanism of the methanol extract of C. owariensis (MECo) in rats. Twenty male Wistar rats were divided into four groups, which include control groups A and B – given distilled water – and treated groups C and D – animals given 100 and 300 mg/kg MECo respectively for 28 days. After the treatment period, gastric mucosal injury was induced for groups B-D by pyloric ligation method. The gastric tissue of animals was collected, processed for histology (haematoxylin and eosin technique), histochemistry (periodic acid-schiff technique) and immunohistochemical staining (for Bcl-2 & Bax proteins). The results of the gastric histomorphology showed prominent and widespread mucosal erosion in positive control group B compared to normal control group A, while treated groups C and D showed only mild or focal mucosal erosion. Furthermore, the histochemical results showed significant increase in mucous cell population in treated groups C and D compared to positive control group B. The immunostaining results showed significant up-regulation of anti-apoptotic Bcl-2 protein and down-regulation of pro-apoptotic Bax protein in the treated groups C and D compared to the control groups A and B. In conclusion, the findings of this study indicate that the increased mucous cell population and modulation of apoptotic signaling highlights the mechanism of gastroprotective activity of MECo.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141035736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with previous wrist surgery and severely impaired carpal anatomy, such as severe osteoarthritis or congenital or acquired deformities that may preclude evaluation and identification of accessory carpal ossicles, were excluded from the study. Four orthopedic surgeons reviewed the computerized tomography scans and identified patients with accessory carpal ossicles on two-dimensional (coronal, axial, and sagittal planes) and three-dimensional computerized tomography reconstructions. Two thousand two hundred thirteen patients, with a mean age of 36.8±12.8 years, were identified and included. Accessory carpal ossicles were detected in 156 (7.1%) subjects, with 186 ACOs identified. The most common accessory carpal ossicles were os praetrapezium (n:34, 1.536%), os triquetrum secundarium (n:28, 1.265%), os epitriquetrum (n:20, 0.903%), os hamuli proprium (n:18, 0.813%), os ulnostyloideum (n:16, 0.723%), os epilunatum (n:12, 0.542%) and os styloideum (n:11, 0.497%) respectively.

The Research and Ethical Committee of the Department of Human Anatomy and Cell Biology, Delta State University, Abraka, gave approval for this study. A descriptive cross-sectional survey with a representative sample of 102 subjects was conducted (58 female and 44 male). The method used was a simple random sampling technique. The age and sex of each subject were obtained using a data form, and intra-oral measurements of the mesio-distal width of the maxillary right central incisors were taken. Results were arranged according to age and sex to ascertain the occurrence of sexual dimorphism; independent sample t test and chi-square test were used as inferential statistical tools. The prevalence of macrodontia was 35.3%; there was a significant sex difference, as p value was <0.05; there was no significant difference within the age groups, as p-value was > 0.05. The mean mesio-distal width was 8.54±0.25 mm in those who did not have macrodontia and 9.63±0.54 mm in those who did have macrodontia.
