Introduction: The aim of the study was to establish normal reference values obtained by fetal speckle tracking analysis of the fetal heart between 17-24 weeks of gestation among Thai fetuses and compare the nomograms with previous studies. Methods: The 4-chamber view of the fetal heart in 79 normal fetuses was analyzed by speckle tracking analysis to determine the best-fit regression model. The 95% reference intervals and Z-score equations of fetal cardiac parameters were computed. Results: The end-diastolic length, width, area, and circumference of the 4-chamber view (4CV) as well as the ventricular end-diastolic length, 24-segment widths, and area were all increased as a function of gestational age (GA) and 5 fetal biometric parameters. In contrast, the global sphericity index (SI), 24-segment SI, and right ventricle/left ventricle width and area ratios did not change with GA or fetal biometric measurements. There were few differences in Z-score reference ranges of fetal cardiac measurements between the current study and previous studies conducted in different patient populations. Conclusion: Our study provided z-score and corresponding centile calculators, 5th and 95th centile reference tables, and corresponding graphs for evaluating the size and shape of the 4CV and the right and left ventricles using 6 independent variables between 17 and 24 weeks of gestation. These results provide normal reference ranges for future studies of fetuses with pathologies that may alter the size and shape of the 4-chamber view and ventricles.

SummaryThis case report describes derangement of the numbered carpal bones resulting in a valgal growth deformity in the right carpus of a seven-month-old dog. Radiographic assessment of the right carpus revealed abnormalities in the size and shape of the numbered carpal bones and carpal valgus. Surgical correction of the growth deformity was planned by partial carpal arthrodesis; however medial collateral laxity associated with the carpal valgus necessitated a pancarpal arthrodesis to achieve correct limb alignment.

Background: Morphological and geometric differences between male and female feet can be the decisive factor of whether well-fitting, functional, and comfortable footwear is available for both men and women. Methods: Optical scans, plaster wrap casts, and a set of manual measurements from the right feet of 51 female participants, aged 20 to 59 years (32 ± 10.2 years), and 39 male participants, aged 22 to 71 years (47.1 ± 12.1 years), were taken to determine which parameters were the most significant in characterizing pedal geometry and which had the largest difference between male and female feet. Results: Analysis showed that the heel-to-ball length (ball length) of the male participants’ feet (181.5 mm) was significantly longer, on average, than that of the female participants’ feet (165.0 mm). The width of the male paticipants’ feet at the ball, instep, and heel regions, as well as the ball circumference, normalized by the ball length, were all significantly larger on average, than the female test participants’ feet. However, toe region, instep, and medial and lateral malleoli heights were larger, on average, for the female participants than for the male. The results show that female feet differ in size and shape from male feet and are not algebraically scaled, smaller versions of male feet, as is often assumed. Conclusions: The study shows that the average male participants’ feet are longer than that of the female participants’ feet, while the female feet are relatively narrower but higher than those of the male participants.

Abstract: Mandibular size and shape are important information especially in terms to figure out the right diagnosis and the type of treatment a patient should have. Human mandible is a key factor for occlusion adjustment, meanwhile maxilla is following the mandible’s position. Several studies show that the stability of mandibular shape and size determines the success of one’s treatment. Each ethnic group has a particular skeletal pattern as well as shape and size of mandible. This study was aimed to obtain the average size and shape of mandibles among local Papuans. This was a descriptive observational study with a cross-sectional design. Samples were obtained by using purposive sampling method. There were 35 local Papuans aged 18-25 years as subjects. Data were obtained by molding the subject’s mandible, therefore, each subject produced a study model. The study model was measured in sagittal (length) and transversal (width) views based on Raberin method. The results showed that the average lengths of local Papuans’ mandibular size in sagittal view (L31, L61, and L71 in a row) were 6.143; 26.463; and 43.743 mm meanwhile the average widths of local Papuans’ mandibular size (L33, L66, and L77 in a row) were 30.857; 50.971; and 60.971 mm. The mandibular shape of most local Papuans was mid shape (45.8%) meanwhile the least shape of them was pointed (5.7%)Keywords: dental arch size, dental arch shape, mandibular, local Papuan Abstrak: Ukuran dan bentuk lengkung gigi rahang bawah sangat diperlukan dalam menentukan diagnosis dan rencana perawatan yang tepat dalam bidang ortodontik karena rahang bawah merupakan faktor stabilitas oklusi, sedangkan rahang atas menyesuaikan pada rahang bawah. Beberapa peneliti menyatakan bahwa kestabilan bentuk dan ukuran lengkung gigi rahang bawah merupakan faktor stabilitas dari hasil perawatan.

In the vascular cambium of Platanus Z and S domains appear in the course of formation of the first annual ring. Their arrangement is connected with the division of the stem into nodes and internodes. In each node a domain of Z and of S type occurs. The longitudinal boundaries between them run along the middle leaf trace and on its opposite side, and the transverse boundaries lie in the nodes. Z-type domains are found on the right below the base of the nearest upper leaf, and S-type domains on the left. As the young cambium forms further rings, the size and shape of the domains changes.

Phlebotomus (Paraphlebotomus) sergenti Parrot, 1917, the proven vector of Leishmania tropica Wright, 1903, the causative agent of anthroponotic cutaneous leishmaniasis, is widely distributed in Morocco. Previous works using molecular markers (ITS2 rDNA and Cyt b mtDNA) have hy-pothesized the existence of multiple closely related populations of sandfly species (cryptic species) that would exhibit distinct vectorial capacities. In this work, descriptive characteristics of wings (size and shape of the right and left wings) were measured in samples collected from fourteen sta-tions in central Morocco. These analyses support the existence of distinct P. sergenti populations, enlightening significant phenotypic variations of P. sergenti’s wings, regarding their size and shape, depending on geographic origin. In addition, geomorphometric analyses of wing’s length, centroid size, alpha, and beta distances allowed clear discrimination of P. sergenti sub-populations. These data pinpoint the adaptative ability of P. sergenti to local environmental conditions. Additional studies are now required to further shed light on the genetic structure of P. sergenti populations in Morocco.

We describe two new species of Cypricercus, Cypricercus alfredo sp. nov. and Cypricercus tiao sp. nov., and briefly redescribe the female of Cypricercus centrurus (Klie, 1940) from Brazilian floodplains. Both new species have the elongated carapace which is characteristic of the genus. Cypricercus alfredo sp. nov. was found as both sexual and asexual populations and has a posterior spine on the right valve and differs from the Brazilian C. centrurus by the position and the size of spine and the size and shape of the carapace. Cypricercus tiao sp. nov. was found as one asexual population only and lacks a posterior spine on the right valve. Cypricercus populations in Brazil mostly consist exclusively of asexual females, but some sexual populations and populations with mixed reproduction can also be found. This genus occurs primarily in the Southern Hemisphere, but some species can also be found in the southern part of North America and in India. We also present a re-appraisal of all species presently allocated to the genus, primarily based on original descriptions.

AbstractSkilled reading requires rapidly recognizing letters and word forms; people learn this skill best for words presented in the central visual field. Measurements over the last decade have shown that when children learn to read, responses within ventral occipito-temporal cortex (VOT) become increasingly selective to word forms. We call these regions the VOT reading circuitry (VOTRC). The portion of the visual field that evokes a response in the VOTRC is called the field of view (FOV). We measured the FOV of the VOTRC and found that it is a small subset of the entire field of view available to the human visual system. For the typical subject, the FOV of the VOTRC in each hemisphere is contralaterally and foveally biased. The FOV of the left VOTRC extends ~9° into the right visual field and ~4° into the left visual field along the horizontal meridian. The FOV of the right VOTRC is roughly mirror symmetric to that of the left VOTRC. The size and shape of the FOV covers the region of the visual field that contains relevant information for reading English. It may be that the size and shape of the FOV, which varies between subjects, will prove useful in predicting behavioral aspects of reading.
