The aim of this study was to determine the external anatomical structures of encephalon in the sparrowhawk. For this purpose, four brains of sparrowhawk were assessed for morphometric measurements and external structures. The average weight of the sparrowhawk brain was approximately 3±0,2 g., while the mean length, width and dorsoventral thickness of sparrowhawk brain were measured 24±2 mm, 19±2 mm and 4±1 mm respectively. Dorsal appearance of the sparrowhawk encephalon showed two cerebral hemispheres, cerebellum, lobus opticus, flocculus and cranial part of medulla spinalis. In lateral aspect of encephalon, pars frontalis cerebri, pars parietalis cerebri, and pars occipitalis cerebri were observed on lateral surface of the hemispherium cerebri from rostral to caudal. The well developed lobus opticus bulged laterally. In ventral view, two small and underdeveloped bulbi olfactorii projected from the rostral pole of the each hemispheres. There was no olfactory tract behind the bulbus olfactorius. Area behind the chiasma opticum constituted the brainstem structures. The midbrain, pons, medulla oblongata and medulla spinalis situated from cranial to caudal respectively in the brainstem. But, there was no distinct borders between the midbrain, pons and medulla oblongata.

AbstractThere are countless morphological variations among the muscles, tendons, ligaments, arteries, veins and nerves of the human body, many of which remain undescribed. Anatomical structures are also subject to evolution, many disappearing and others continually emerging. The main goal of this pilot study was to describe a previously undetected anatomical structure, the plantaris ligamentous tendon, and to determine its frequency and histology. Twenty-two lower limbs from 11 adult cadavers (11 left, and 11 right) fixed in 10% formalin were examined. The mean age of the cadavers at death was 60.1 years (range 38–85). The group comprised six women and five men from a Central European population. All anatomical dissections of the leg and foot area accorded with the pre-established protocol. Among the 22 lower limbs, the PLT was present in 16 (72.7%) and absent in six (27.3%). It originated as a strong fan-shaped ligamentous tendon from the superior part of the plantaris muscle, the posterior surface of the femur and the lateral aspect of the knee joint capsule. It inserted to the ilio-tibial band. Histologically, a tendon and ligament were observed extending parallel to each other. A new anatomical structure has been found, for which the name plantaris ligamentous tendon is proposed. It occurs around the popliteal region between the plantaris muscle, the posterior surface of the femur, and the ilio-tibial band.

Abstract During the present study, specimens were collected from selected sites of Cholistan desert and Kalabagh Game Reserve, Punjab province, Pakistan. Each captured specimen was tagged with voucher number and morphometric measurements were taken. The average snout to vent length was 172.559±1.40 mm and average weight was 92.1±1.30 g. The DNA of Uromastyx hardwickii was amplified and sequenced using 16S rRNA primer set. The obtained DNA sequence has shown reliable and clear species identification. After trimming ambiguous bases, the obtained 16S rRNA fragment was 520 bp while 16S rRNA fragments aligned with closely matched sequence from NCBI comprised of 510 bp. Closely matched sequences of genus Uromastyx were retrieved from NCBI in blast searches. Neighbour-joining tree of genus Uromastyx was constructed based on p-distance using MEGA X. The mean intraspecific variation was 0.095±0.01 while intraspecific variation was ranging from 0-1%. Similarly, interspecific variation of Uromastyx hardwikii with Saara asmussi, Uromastyx alfredschmidti, Uromastyx geyri, Uromastyx thomasi, Uromastyx alfredschmidti was 0-12%, 0-19%, 0-19%, 0-20%, 12-19% respectively. The newly produced DNA was submitted to NCBI and accession number was obtained (MW052563.1). Results of current study provided information about the molecular and morphological identification of Genus Uromastyx. In our recommendation, comprehensive molecular based identification of Pakistan’s reptiles is required to report any new or subspecies from country.

BACKGROUND The posterior half of the foot is made of seven tarsal bones. Talus is seen above calcaneus. It has a head, neck and body. There are three facets anterior, middle and posterior facets that articulate with corresponding facets of the calcaneus. The middle and posterior facets are separated by a groove sulcus tali. We wanted to know the morphometric measurements of talus in South Keralites in this study. METHODS The study was done on 68 dry human tali of unknown age and sex in the Department of Anatomy, Government medical college, Trivandrum. The measurements were taken i.e., length, width and height of talus using vernier calipers. The length, width and height of sulcus tali were also measured. The range and mean of measurements were estimated. The calcaneal facets were studied and classified to find the most common and least common types. Data analysis was performed using SPSS ver 16.0. RESULTS The mean anteroposterior length of the talus was 4.84 ± 0.44 cm. The mean transverse length was 3.46 ± 0.47 cm. The mean height of the talus was 2.56 ± 0.31 cm. Anteroposterior length ranged from 3.84 to 6.07. The transverse length of the talus ranged from 2.81- 5 cm. Height of talus ranged from 2 - 3.2 cm. The mean anteroposterior length of sulcus tali was 2.09 ± 0.45 cm. The mean height of sulcus tali was 0.55 ± 0.09 cm. The mean width of sulcus tali was 0.62 ± 0.30 cm. Anteroposterior length of sulcus tali ranged from 1.4 - 3.8 cm. The transverse length of sulcus tali ranged from 0.34 to 1.6 cm. Height of sulcus tali ranged from 0.2 to 0.7 cm, regarding the type of facets, type 2 was most common and type 4 was found to be absent. CONCLUSIONS The adequate knowledge of the anatomy of the talus is significant not only to the anatomists but also to the orthopaedic surgeons as fractures of the talus are quite common and lead to avascular necrosis, arthritis and when unrecognized, chronic pain and non-union 3. Talectomy has been described as a limb-saving procedure for the treatment of neglected talipes equinovarus deformity. KEY WORDS Talus, Sulcus Tali, Calcaneal Facet Morphometric Measurements of Talus in South Keralites.

Background: There are a few studies about the evaluation of maxillary first premolars internal structure with micro-computed tomography (micro-CT). The aim of this study was to assess morphological features of the pulp chamber in maxillary first premolar teeth using micro- CT. Methods: Extracted 15 maxillary first premolar teeth were selected from the patients who were in different age groups. The distance between the pulp orifices, the diameter of the pulp and the width of the pulp chamber floor were measured on the micro-CT images with the slice thickness of 13.6 µm. The number of root canal orifices and the presence of isthmus were evaluated. Results: The mean diameter of orifices was 0.73 mm on the buccal side while it was 0.61 mm on palatinal side. The mean distance between pulp orifices was 2.84 mm. The mean angle between pulp orifices was -21.53°. The mean height of pulp orifices on the buccal side was 4.32 mm while the mean height of pulp orifices on the palatinal side was 3.56 mm. The most observed shape of root canal orifices was flattened ribbon. No isthmus was found in specimens. Conclusion: Minor anatomical structures can be evaluated in more detail with micro-CT. The observation of the pulp cavity was analyzed using micro-CT.

Abstract Introduction The central ridge of the patella is the thickest area of patella and varies among patients. This cadaveric study identified the location and thickness of the bone at the central patella ridge for bone-patellar tendon-bone (BPTB) harvesting. Materials and methods Fifty cadaveric knees were assessed. First, the morphology, length, width, and location of the central patellar ridge were recorded. Then, we transversely cut the patella 25 mm from the lower pole and measured the thickness of the anterior cortex, cancellous bone, and cartilage from both the mid-patella and the central ridge location. Finally, the depth of the remaining cancellous bone at the mid-patella was compared to the bone at the central ridge. Results The location of the central-patellar ridge deviated medially from the mid-patella in 46 samples with an average distance of 4.36 ± 1 mm. Only 4 samples deviated laterally. The mean patella length was 41.19 ± 4.73 mm, and the width was 42.8 ± 5.25 mm. After a transverse cut, the remaining cancellous bone was significantly thicker at the central ridge compared to the bone at the mid-patella. Conclusions Most of the central patellar ridge deviated medially, approximately 4 mm from the mid-patella. Harvesting the graft from the central ridge would have more remaining bone compared to the mid-patella.

Purpose: Our purpose was to clarify and further characterize the changes in height, length, width, volume, and shape in the normal pituitary gland and in width in the infundibulum during pregnancy and the first 6 months post partum. Material and Methods: Cranial MR imaging was performed in 78 women who were pregnant in the second or third trimester or who were post partum, and in 18 age-matched control subjects who were not pregnant. Volume measurements were performed in 2 ways; volume 1=1/2xheightxlengthxwidth; and volume 2=area (measured by trackball)xslice thickness Results: Gland volume, height, width, length, and convexity, and infundibular width increased during pregnancy. the highest values were seen during the 3 days immediately post partum. When compared with volunteers, volumes 1 and 2 showed the largest increase (120%) among the parameters. Gland height showed the best correlation (r=0.94, p>0.00001) with gestational age. the mean height of the gland was 8.76 mm in the third trimester. None of the pregnant women had a gland height of above 10 mm during pregnancy. Only 2 subjects had gland heights of 10.04 and 10.2 mm during the 0–3 days post partum. After this first post-partum period of 3 days, the gland size, shape, and volume and the infundibular width returned to normal within 6 months Conclusion: the pituitary gland enlarges in three dimensions throughout pregnancy. During pregnancy, the volume of the gland shows the highest percentage of increase compared to its length, height, and width. the maximum height of the gland does not exceed 10 mm during pregnancy but it may exceed 10 mm during the 3 days immediately post partum.

Since 2002 the Denver Zoological Foundation has produced 28 African hunting dog (Lycaon Pictus) puppies in 3 litters (7, 14 and 7 pups) from the same dam and sire. Wellness examinations were performed on each puppy. The wellness examinations spanned the range of 6-14 weeks of age. During the wellness examinations, in addition to physical examinations and vaccinations, blood samples for complete blood counts and sera biochemistry were obtained.Weights, morphometric measurements, rectal cultures for enteric pathogens and dental eruption patterns were recorded. Blood samples from each age group were compared with adult values from the Denver Zoo. It was noted that animals from the 14-pup litter were 63.6 % of the mean weight of the two 7-pup litters, but size differences (in, for example, total bodylength) were less apparent. Two organisms were recovered from rectal cultures, namely Yersinia enterocolitica (n = 2) and Plesiomonas shigelloides (n = 3). The following deciduous eruption patterns were also noted; at 6 weeks, I1-3, i1-3, C1, c1, P1-2 and p1-2 (n=7) were present, at 9-10 weeks, P3 and p3 (n=21) , and finally at 12-14 weeks, P4 (n = 28).

The objective of the present study was to test and establish mathematical models to estimate the leaf area of Garcinia brasiliensis Mart. through linear dimensions of the length, width and product of both measurements. In this way, 500 leaves of trees with age between 4 and 6 years were collected from all the cardinal points of the plant in the municipality of São Mateus, North of the State of Espírito Santo, Brazil. The length (L) along the main midrib, the maximum width (W), the product of the length with the width (LW) and the observed leaf area (OLA) were obtained for all leaves. From these measurements were adjusted linear equations of first degree, quadratic and power, in which OLA was used as dependent variable as function of L, W and LW as independent variable. For the validation, the values of L, W and LW of 100 random leaves were substituted in the equations generated in the modeling, thus obtaining the estimated leaf area (ELA). The values of the means of ELA and OLA were tested by Student’s t test 5% of probability. The mean absolute error (MAE), root mean square error (RMSE) and Willmott’s index d for all proposed models were also determined. The choice of the best model was based on the non significant values in the comparison of the means of ELA and OLA, values of MAE and RMSE closer to zero and value of the index d and coefficient of determination (R2) close to unity. The equation that best estimates leaf area of Garcinia brasiliensis Mart. in a way non-destructive is the power model represented by por ELA = 0.7470(LW)0.9842 and R2 = 0.9949.

Abstract Fish that are incidentally caught by shrimp trawling represent a predictable and abundant resource for feeding several bird species, especially for the gull Larus dominicanus. This fishing activity is subject to disruptions throughout the year during closed fishing seasons, when other fishing modalities are exercised, which can alter the composition, abundance and size of the fish bycatch. This study evaluated the influence of the restriction of fishing period of shrimp (closed season) on the diet of L. dominicanus, on the Paraná State coast. From December 2013 to August 2014, 10 pellets were collected per month in two distinct areas that have shrimp trawl fishery as the main economic activity: one continental and another in an estuarine island. In total, 920 fish were identified, divided into four families and 15 species, especially the family Sciaenidae with 11 species. There were differences in abundance and biomass of species between areas and between seasons of pre-closure, closure and post-closure. Differences for the mean total length of the species were only detected between the pre-closed and closed seasons in one area. This study evidenced the strong relationship between L. dominicanus and the shrimp trawl fishery, the species composition identified in the pellets and their respective morphometric measurements follow the same pattern of the literature for fish discarded in trawling activities.

The study was conducted due to the economic importance of horses and shortage of information on electrocardiographic parameters of horses in Sokoto, Nigeria. This study established the normal electrocardiographic parameters of racing and non-racing horses in Sokoto and statistically compared the values. The study used forty horses comprising of 20 racing and 20 non-racing horses with mean age of 8 ± 0.5 years and average weight of 200 ± 2.0 kg. ECG was recorded using the base apex system with the animals in standing position using single lead channel ECG recorder (EDAN VE-100 manufactured by Edan instruments China). The paper speed was set at 25mm/s while the sensitivity of the machine was adjusted to 10 mm/mV. The durations and amplitudes of P, R and T, the durations of Q and S and the durations of PR, QRS and QT intervals were all determined. These parameters were determined for the three standard limb leads (I, II and III) as well as the augmented limb leads (aVR, aVL and aVF). Descriptive statistics using SPSS version 16 was used to calculate the means and standard error of mean at 95 % confidence interval. One-way ANOVA was used to compare between the values of the racing and non-racing horses. The highest values of P amplitude, R amplitude, Q amplitude, QRS complex and P-R interval were recorded in racing horses, while highest T wave amplitude was recorded in non-racing horses. Highest duration of P wave, T wave and QRS was recorded in racing horses while highest duration of Q wave was recorded in non-racing horses. Significant difference was found in the T amplitude in racing horses in lead aVF. The mean heart rate for the racing and non-racing horses was 80.3 ± 8.4 and 63.1 ± 9.2 beats/minute respectively. Higher values recorded in racing horses indicates that exercise has influence on electrical activities in horses. Keywords: Electrocardiograph, Non-racing horses, Parameters, Racing horses, Sokoto
