Abstract Purpose The aim of this study was to demonstrate the utility of three-dimensional computed tomography (3D) CT rib study in presurgical planning to select the autologous rib cartilage graft for pinna reconstruction. Materials and Methods Total of 35 patients of microtia for autologous rib graft from April 2017 to February 2020 were evaluated in this study. All patients had a plain low-dose multislice CT chest. The length of costal cartilages of sixth to ninth ribs bilaterally and width and height of sixth and seventh rib costal cartilage synchondrosis were measured in 3D reconstructed true size coronal images with best possible length displayed. All patients had high-resolution computed tomography (HRCT) temporal studies done to evaluate for associated anomalies in external canal, middle ear cavities, and inner ear structures. Eleven patients had simultaneous HRCT temporal bone done after plain CT chest and rest who had done recent prior study were reviewed without repetition of study. Results There were 19 males and 16 females for 3D CT rib study. Average age of the participants was 16.5 years. The average width of synchondrosis of sixth and seventh rib was 15.4 mm on right side and 14.7 mm on left side, average height of synchondrosis was 28.5 mm on right side and 30.7 mm on left side. Average length of the eighth rib costal cartilage was 88.6 mm on the right side and 90.5 mm on the left side. Average length of the ninth rib was 63.2 mm on the right side and 58.2 mm on the left side. Costal cartilage calcifications were present in 9 patients. Conclusion Preoperative 3D CT rib study provides accurate measurements of rib stock for sculpting autologous ear graft.

Abstract. Ahmad J, Kandowangko NY, Solang M, Najamuddin E. 2021. Morphological characteristics and nutritional value of binthe kiki, a local maize variety from Gorontalo, Indonesia. Biodiversitas 22: 3523-3529. Gorontalo is among the coastal areas in Tomini bay with diverse varieties of local maize. Despite that, the population of local maize has seen a steady decline over the years. A literature study reports that local maize has adapted well to the environment in which it grows. Local maize is also hailed by the community as a source of food, animal feed, and the main ingredient of traditional medicines. The present study aims to investigate the morphological characteristics and nutritional value of binthe kiki local maize variety. Employing a quantitative descriptive method, the data of morphological characteristics were collected by referring to the maize descriptor guidelines, while the data of the nutritional value of maize kernels (regarding the proximate and mineral contents) were analyzed by referring to the Indonesian National Standard and Association of Official Agricultural Chemists (AOAC) standards. The findings show that the morphological characteristics of binthe kiki variety are as follows: (i) an average plant height of 161 cm; (ii) each stalk has three cobs with an average height of 119 cm; (iii) an average stalk circumference of 6.35 cm; (iv) an average of 12 leaves per stalk; (v) 71.12 cm of an average length of leaves; (vi) 5.21 cm of an average width of leaves; (vii) the direction of the leaf blade, on average, is slightly curved; (viii) the average leaf tip is pointed; (ix) an average cob length of 8.4 cm; (x) an average cob diameter of 2.74 cm; (xi) an average cob weight (without husk) of 0.054 kg/cob; (xii) an average of 24 kernels per row; (xiii) an average weight per 1000 kernels of 145 gram. Binthe kiki variety has high contents of protein, carbohydrate, zinc, and calcium, yet it is low in fat contents compared to other varieties.

Abstract For simulations of flow and microbial conversion reactions, related to modeling of simultaneous extraction and fermentation process in a single sugar beet cossette a software package OpenFOAM was used. The mass transfer of the components (sucrose, glucose, fructose and ethanol) in the studied system was controlled by the convection and diffusion processes. Microbial conversion rates and yield coefficients were experimentally determined and/or estimated by mathematical simulation. Dimensions of the model sugar beet cossette (SBC) were: average length of cosettes 40.10 mm, average thickness 3.32 mm and average width 3.5 mm, and represented in the model as a square-shape cross-section mathematical simulation. Dimensions of the model sugar beet cossette (SBC) were: average length of cosettes 40.10 mm, average thickness 3.32 mm and average width 3.5 mm, and represented in the model as a square-shape cross-section used to study the mass transfer and microbial conversion rates on the scale of single sugar beet cossette in the short time scales (up to 25 s). This model can be used for simulation of extractant flow around single sugar beet cossette as well as for description of simultaneous extraction and fermentation process in the studied system.

Objective. To analyze the penile and urethral meatus biometry and its correlation with meatoplasty during endoscopic resections. We also propose a new classification for urethral meatus morphology.Materials and Methods. We prospectively studied 105 patients who underwent prostate and bladder transurethral resections. We performed standardized measurement of penile and urethral meatus biometry followed by penile photo in the front position. The need to perform meatoplasty or dilatation during resectoscope introduction was registered. Data were analyzed comparing the correlation between two groups: without intervention (Group A) and with intervention (Group B).Results. We observed in Group A and Group B, respectively, the average length of urethral meatus of 1.07 cm versus 0.75 cm (p<0.001) and average width of urethral meatus of 0.59 cm versus 0.38 cm (p<0.001). Considering the morphology of the urethral meatus, we propose a new classification, in the following groups: (a) typical; (b) slit; (c) point-like; (d) horseshoe; and (e) megameatus. The point-like meatus was the one that most needed intervention, followed by the slit and the typical meatus (p<0.001).Conclusions. Point-like and slit-shaped urethral meatus, as well as reduced length and width of the urethral meatus, are the determining factors.

Scavenging Efficiency

Summary Maternal age is a significant factor influencing in vitro fertilization (IVF) outcomes. Oxidative stress (OS) is one of the major causes of age-related cellular and molecular damage. The purpose of this work was to investigate the correlation between maternal age with intrafollicular antioxidants and OS markers in follicular fluid (FF), and also to determine the OS status in patients of advanced age. This study was a prospective study including 201 women undergoing IVF whose age was between 24 and 45 years old. FF samples were obtained from mature follicles at the time of oocyte retrieval. After treatment of FF, lipid peroxidation levels (MDA) and enzyme activities such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR) and glutathione (GSH) level were evaluated using spectrophotometry. The results indicated that the age cutoff point for increasing the MDA level was fixed at 37 years, allowing the study to be differentiated into two age groups. Group I included patients whose age was less than 37 years, and group II included patients whose age was greater than or equal 37 years. Statistical analysis revealed that MDA and GSH levels and GR activity were significantly higher in group II compared with group I. The SOD and CAT activities were significantly less in group II compared with group I. We concluded that from 37 years old a reproductive ageing was accompanied by a change in the antioxidant pattern in FF that impaired reactive oxygen species scavenging efficiency.

Background: Affections of eye commonly encountered in all the species of animals. If these not treated in time, the vision may be hampered, this may impair the physical ability, utility and productivity of animals leading to economic loss to the animal owners. Corneal dystrophies like basement membrane dystrophy, stromal dystrophy, endothelial dystrophy, corneal erosions and corneal ulcerations etc., seen in the aged buffaloes. The current study was carried out to establish basic data and to provide authentic information to the clinicians on ageing changes in eyes of buffaloes.Methods: The study on age related changes in the cornea was conducted on 63 eye balls of locally available buffaloes of different breeds in and around Proddatur. These buffaloes were categorized into 3 groups based on their age i.e., group I (1-5 yrs), group II (6-10 yrs) and group III (11 yrs and above) buffaloes. The eyeballs were isolated and fixed with Davidson’s fluid. The paraffin sections of cornea were subjected for routine histological study.Result: The mean total thickness (µm) of cornea was increased from group I to III animals and it was 747.22±13.57, 853.33±11.05 and 897.22±8.06. Hence, The mean thickness (µm) of all five layers of cornea increased with advancement of age. Superficial corneal epithelial layer was made up of non keratinized stratified squamous epithelium with 6 to 7 layers at early age and 12-14 layers of cells in adult animals. The mean thickness (µm) of corneal epithelium in group I to III animals was 117.04±3.37, 122.59±2.23 and 133.71±3.55 respectively. Bowman’s membrane of cornea was measured 12.97±0.86, 17.22±0.55 and 18.71±0.68 in group I, II and III animals respectively. The mean thickness (µm) of corneal stroma in group I to III animals was 600.75±10.33, 672.22±10.46 and 690.00±5.32 respectively. This was mainly due to progressive increase in number of collagenous lamellae. The keratocytes became thin in old animals. Thickness of posterior band zone (PBZ) of Descemet’s membrane was increased with advancement of age. The mean thickness (µm) of Descemet’s membrane and endothelium together was in group I, II and III animals was 16.48±0.91, 41.29±2.25 and 54.82±1.44 respectively. The corneal endothelial cells were enlarged and increased in size in old buffaloes. The age related pigmentation was also noticed in epithelium and stroma of cornea in animals of group III. Density of sub basal nerve plexuses between the stroma and the corneal epithelium was not altered with advancement of age.

The study evaluated the fish community assemblage in the sections of the Subri river, the Ankobra river, and the “galamsey” pond within the Prestea community as impacted by alluvial mining activities. Gill nets of length 10 m and mesh size 1.27 cm were used to trap fish of average length 25.25 cm whilst cane baskets were used to trap fish of average width 10.40 cm using the catch and recapture method. All the 46 fish samples identified belong to 10 genera and 5 families. The Chichlidae was the dominant family, accounting for 60% of the total families observed. With an H’ index of 1.57 the Subri river had the most fish diversity in comparison with the Ankobra river and the “galamsey” pond, which had 1.21 and 0.71, respectively. Similarly, the Subri river had a more complex fish community structure than the Ankobra and “galamsey” pond. The dominant species, Oreochromis niloticus, has not yet been evaluated by the IUCN, but the least dominated Brienomyrus brachyistus could be regarded as “least concern”. Notwithstanding, these fish are essential for food by the local communities. There is a possibility that the alluvial mining might have influenced the complexities of fish species communities. Thus conservation efforts must be promoted to sustain fish communities and overall freshwater ecosystem health.

Abstract Background Rhinoplasty in the elderly requires different surgical approaches due to the morphological and structural changes affecting the nose over time. Objectives In this study, the authors aimed to evaluate the age-related cellular and architectural changes of nasal cartilages and soft tissue attachments. Methods This prospective study included 80 patients who underwent rhinoplasty. Patients were divided into 2 groups according to age. Group I included 40 patients ranging in age from 19 to 39 years. Group II included 40 patients aged at least 40 years. Samples from nasal cartilages (upper lateral, lower lateral, and septum) and nasal attachments (interdomal, inter-cartilaginous, and septo-crural) were taken. All specimens were evaluated histologically to detect age-related changes. A modified version of the Mankin grading scale was used to score each nasal cartilage sample. All attachment samples were examined by image analysis for quantitative assessment. The results were correlated to preoperative anthropometric measurements of nasolabial angle and nasal projection. Results Histologically, in group II, the cartilage matrix showed fibrinoid degeneration with a significant decrease in the number of chondrocytes and increased perichondrial fibrosis compared with group I. Attachments in group II showed a lower number of blood vessels and decreased percentage of collagen bundles. Modified Mankin scores were significantly higher in group II, indicating weak cartilages compared with group I. There was negative correlation and significance between projection, nasolabial angle, cartilages, and attachments in study groups. The linear regression model revealed that the lower lateral cartilage is the cartilage that is most affected by the aging process. Conclusions These findings not only enhance our current understanding of the natural changes that occur in the nose during aging but may also affect surgical decision-making when grafting or suturing are considered during rhinoplasty.

Background: The Blue bull (Boselaphus tragocamelus) is one of the biggest antelopes in Asia and is widely distributed in both the forests and adjoining villages with enough green grass.Methods: The present study was carried out on the mandible of six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. The biometrical parameters were measured by scale, graduated tape and digital Vernier’s caliper. The statistical analysis of the recorded data was done by independent samples t-Test with Systat Software Inc, USA and SPSS 16.0 version software.Result: The mandible of Blue bull consisted of two rami, i.e. horizontal and vertical rami. The two halves of this bone fused incompletely at the mandibular symphysis, situated at the midline. The average length of horizontal ramus of mandible was found to be 24.7±1.02 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 35.4±1.97 cm. Similarly, the average thickness of vertical ramus at the base was found to be 0.53±0.001 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 0.80±0.002 cm. The average cranio-caudal length of mandibular notch was found to be 1.32±0.01 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 1.44±0.02 cm. Most of the biometrical observations on different parameters of mandible of Blue bull were having significantly (P less than 0.05) more values in males than females. Conclusion: Most of the biometrical observations on different parameters of mandible of Blue bull were having significantly (p less than 0.05) more values in males than females. The present gross and biometrical studies would be useful to the wild life professionals for determination of sex of this animal and solving vetero-legal cases related with this species.
