SUMMARYIn Volume VII, 1958 of the A. Ge. Me. Ge a research on the dermatoglyphics of an incestuous family (5 children, their mother, grandmother and grandfather, the latter also being the father of the children) was published. The present paper deals with the morphological features of the face, i.e. the soft parts of the mouth and chin region, of the eye region and of the external nose of the same family.Theoretically speaking, in a case like this— owning to the increased amount of common alleles—an unusually close phenotypical resemblance among the children might be expected, as, in fact, demonstrated by the morphological analysis. The characters subject to changes by age represent an almostt step by step development and this is confirmed by the two observations carried out in 1934 and 1939.Considering the variations caused by age, the children don't exceed, generally, the difference of monozytic twins.Regarding the phenotypical similarity to the adults the theoretical expectation has been more than confirmed. There are close affinities with the grandfather and the mother of the children resembling him. Only a few features are in common with the grandmother and these, for the most part, are features typical of earlier stages of development. As some traits of this kind are characteristic for the grandmother these resemblances are considered to be of a temporary nature only.The study of the dermatoglyphics revealed a surprising conformity between the children, their mother and their grandfather, while the grandmother differed. In addition two of the children showed a few widely divergent rare traits. Compared with the dermatoglyphics the isolated minor deviations in the morphological characters of the face seem of no importance. On the whole one is impressed how rapidly ancestral loss (« Ahnenverlust ») can lead to an extensive phenotypical homogeneity in a family.

Rhynchonellida is the stratigraphically oldest and phylogenetically most basal of the extant rhynchonelliform brachiopod orders, yet phylogenetic relationships among rhynchonellides are poorly known. The fourteen named rhynchonellide superfamilies (four of which have extant representatives) were defined primarily on the basis of features of the dorsal cardinalia, particularly crural morphology, but their homology and polarity have not been investigated rigorously. Superfamily monophyly is unclear, as is the evolution of several distinctive rhynchonellide morphological features, such as crura.The purpose of this study is to investigate the phylogenetic relationships among extant rhynchonellide genera using skeletal characters, and to compare the results with the current classification, elucidating the evolution of morphological features in the process. We completed parsimony-based and Bayesian analyses using fifty-eight characters of the interior and exterior of the shell that vary among the nineteen extant genera. Our results are readily interpretable with respect to the classification, and indicate that Hemithiridoidea, Dimerelloidea, and (in some analyses) Pugnacoidea appear to be monophyletic. Species classified in Dimerelloidea and Pugnacoidea, and in certain cases Hemithiridoidea, each form derived subclades that evolve from within a paraphyletic Norelloidea at the base of each subclade. Raduliform crura appear to be the most basal, phylogenetically; five other crural morphologies evolve from the raduliform state. However, morphological characters currently uniting genera in rhynchonellide superfamilies are not clearly diagnostic and exhibit a relatively high degree of homoplasy overall, suggesting that consistency with the classification may be based on a false sense of confidence in rhynchonellide morphology to clearly elucidate evolutionary relationships. Published molecular phylogenetic hypotheses conflict with the morphological topologies, further supporting this possibility.The evolutionary trends among diagnostic characters of Recent rhynchonellides appear to reflect successive juvenilization in adult morphology in several subclades, suggesting that heterochrony may have played an important role in the evolution of the group.

Relevance. The high prevalence of dysplastic disorders involving connective tissue, and its negative effecton the development of dentoalveolar anomalies, carious and non-carious lesions of the teeth, periodontopathy, temporomandibular joint issues in the child population, lay the basis for improving diagnostics algorithms. Enhancing the already available standards is of greatest importance for children at the initial stages of diagnostics when evaluating the external signs of dysplastic disorders.Purpose – improving diagnostics algorithms for connective tissue dysplasia (CTD) in children in primary dental care facilities based on the evaluation of external phenotype signs and maxillofacial morphological features.Materials and methods. Depending on the external phenotype manifestations severity, as well as on laboratory, clinical and instrumental signs, the 92 children with CTD were divided into groups with mild, moderate and severe degrees of undifferentiated dysplasia. Gnathometric and biometric examinations of the maxillofacial area were performed through traditional methods, whereas the diagnosis was set following the generally accepted classifications. The diagnosis confirmation implied evaluation through cone beam computed imaging.Results. The nature and the intensity of morphofunctional disorders in the craniofacial structures (“small” stigmas) depend on the severity of connective tissue dysplastic disorders.Conclusions. The change direction vector in the facial and brain parts of cranium in children with CTD is aimed at increasing hypoplastic tendencies and dolichocephalia, proof to that being the following constitutional and morphological features: the prevalence of the vertical type of face skeleton growth over the horizontal and neutral ones; a convex face profile with a disproportionate general heights of the face skeleton; reduction of latitudinal with an increase in altitude facial parameters; a narrow short branch of the lower jaw; the upper jaw displaced downwards and forward; a decrease in the size of the apical basis of the lower dentition, the lower jaw body, as well as the height and width of the lower jaw branches.

The Difference

Distant hybridization is known to play an important role in expanding the gene pool of any crop. It is believed that the combination of different genomes in one nucleus, as a rule, is accompanied by the phenomenon of “genomic shock”, resulting in a variety of genetic and epigenetic changes. This provides a wealth of material for the selection of genotypes adapted to different environmental conditions. Interspecific hybrids in different combinations were obtained in the genus Brassica, however, until now, interest in distant hybridization in this genus has not died out, since such important crops as rapeseed and mustard demand an improvement of many important agronomic traits. The aim of this work was to study the degree of manifestation of morphological characters of a leaf, flower, and plant as a whole in the hybrid obtained by crossing of brown mustard of the variety Slavyanka and a collection specimen of spring rape. Seeds were sown in the spring of 2019 in a field with 30 cm row width. During the flowering period a number of morphological characters of a flower, leaf, and the whole plant were analyzed. Each parameter was evaluated with 10 plants. The degree of dominance in first-generation hybrid was calculated by the formula of Beil, Atkins (1965). The dominance coefficients were not determined in the case when the difference between the parental samples was insignificant. Differences between parental samples were determined by Student t-test. The level of heterosis was calculated according to the formula of Rasul et al (2002). In a mustard-rapeseed hybrid, the size of the leaves of the lower row was inherited by the type of rapeseed, which had larger leaves than mustard. The height of the hybrid plant was inherited by the type of mustard (hp = 1.32, Ht = 4.89%), and intermediate inheritance was observed for the length of the internodes (hp = -0.48). The size of the flower petals and sepals was inherited by the type of rapeseed, and significant heterosis was observed for the length of the pistil (Ht = 33.57%). The data obtained are of interest for understanding the interaction of genes of different genomes in the genus Brassica.

Abstract Background Our understanding of the functional anatomy of the face is constantly improving. To date, it is unclear whether the anatomic location of the line of ligaments has any functional importance during normal facial movements such as smiling. Objectives It is the objective of the present study to identify differences in facial movements between the medial and lateral midface by means of skin vector displacement analyses derived from 3D imaging and to further ascertain whether the line of ligaments has both a structural and functional significance in these movements. Methods The study sample consisted of 21 healthy volunteers (9 females & 12 males) of Caucasian ethnic background with a mean age of 30.6 (8.3) years and a mean BMI of 22.57 (2.5) kg/m 2. 3D images of the volunteers’ faces in repose and during smiling (Duchenne type) were taken. 3D imaging-based skin vector displacement analyses were conducted. Results The mean horizontal skin displacement was 0.08 (2.0) mm in the medial midface (lateral movement) and was -0.08 (1.96) mm in the lateral midface (medial movement) (p = 0.711). The mean vertical skin displacement (cranial movement of skin toward the forehead/temple) was 6.68 (2.4) mm in the medial midface whereas it was 5.20 (2.07) mm in the lateral midface (p = 0.003). Conclusions The results of this study provide objective evidence for an antagonistic skin movement between the medial and the lateral midface. The functional boundary identified by 3D imaging corresponds to the anatomic location of the line of ligaments.

In the face of climate change, extreme climates are becoming more frequent. There were severe droughts in Taiwan in 2020, 2014–2015, and 2002. In these years, the paddy fields were kept fallow to save water and transfer agricultural water to non-agricultural use. On the other hand, with global warming, the existence of paddy fields may be one of the natural solutions to regional temperature mitigation. This study used remote sensing to quantify the difference in temperature between paddy fields and urban areas. The result of overall surface temperature deductive analysis revealed that the temperature in the whole Taoyuan research area was 1.2 °C higher in 2002 than in 2003 because of fallowing of the paddy field, while in the Hsinchu research area, it was 1.5 °C higher in 2002 than in 2003, due to the same reason described above. In terms of the difference in land use, for the Hsinchu research area, the surface temperature deductive result showed that the average paddy field temperature in 2002 was 22.3 °C (sample area average), which was 7.7 °C lower than that of the building and road point and 4.3 °C lower than that of the bare land point. The average paddy field temperature in 2003 was 19.2 °C (sample area average), which was 10.1 °C lower than that of the building and road point and 8.3 °C lower than that of the bare land point. Then this study evaluated the economic valuation of the paddy field cooling effect using the contingent valuation method. Through the paddy field cooling effect and in the face of worsening extreme global climate, the willingness to pay (WTP) of the respondents in Taiwan for a decrease of 1 °C with regard to the regional microclimate was evaluated. It was found that people in Taiwan are willing to pay an extra 8.89 USD/per kg rice/year for the paddy for a decrease in temperature by 1 °C in the regional microclimate due to the paddy field. Furthermore, this study applied the benefits transfer method to evaluate the value of a decrease of 1 °C in the regional microclimate in Taiwan. The value of a decrease of 1 °C in the regional microclimate in Taiwan is 9,693,144,279 USD/year. In this regard, the economic value of 1 °C must not be underestimated. In conclusion, more caution is needed while making decisions to change the land use of paddy fields to other land uses.

A new toad, Rhinella cerradensis, is described, including its tadpole and the advertisement call. The new species occupies Cerrado habitats in the Brazilian states of Piauí, Bahia, Goiás, Minas Gerais, and Distrito Federal. The species is characterized by its large size; absence of tibial glands; well developed cranial crests; short hands; sexually dimorphic coloration; and by the absence of a spiracle tube of the tadpole. The new species is included in the Rhinella marina group by the presence of a jagged suture formed by the articulation between the pterygoid medial ramus and the parasphenoid alae, as well as other shared morphological features. Morphological characters and statistical analyses inferred by morphometric feature suggest the existence of two subgroups of species within R. marina group. However, taxonomic rearrangements are not made here and await phylogenetic analysis.

Object. Transthoracic endoscopic T2–3 sympathectomy is currently the treatment of choice for palmar hyperhidrosis. Compensatory sweating of the face, trunk, thigh, and sole of the foot was found in more than 50% of patients who underwent this procedure. The authors conducted this study to investigate the associated intraoperative changes in plantar skin temperature and postoperative plantar sweating. Methods. One hundred patients with palmar hyperhidrosis underwent bilateral transthoracic endoscopic T2–3 sympathectomy. There were 60 female and 40 male patients who ranged in age from 13 to 40 years (mean age 21.6 years). Characteristics studied included changes in palmar and plantar skin temperature measured intraoperatively, as well as pre- and postoperative changes in plantar sweating and sympathetic skin responses (SSRs). In 59 patients (59%) elevation of plantar temperature was demonstrated at the end of the surgical procedure. In this group, plantar sweating was found to be exacerbated in three patients (5%); plantar sweating was improved in 52 patients (88.1%); and no change was demonstrated in four patients (6.8%). In the other group of patients in whom no temperature change occurred, increased plantar sweating was demonstrated in three patients (7.3%); plantar sweating was improved in 20 patients (48.8%); and no change was shown in 18 patients (43.9%). The difference between temperature and sweating change was significant (p = 0.001). Compared with the presympathectomy rate, the rate of absent SSR also significantly increased after sympathectomy: from 20 to 76% after electrical stimulation and 36 to 64% after deep inspiration stimulation, respectively (p < 0.05). Conclusions. In contrast to compensatory sweating in other parts of the body after T2–3 sympathetomy, improvement in plantar sweating was shown in 72% and worsened symptoms in 6% of patients. The intraoperative plantar skin temperature change and perioperative SSR demonstrated a correlation between these changes.

Morphogenetic Analysis

Morphological features of garnets from the Upper Paleozoic Dyukunakh placer were studied and the conditions of their morphogenesis were interpreted. As a result of the morphogenetic analysis, it was found that garnets have evolved in exogenous conditions, including extreme wear in coastal marine conditions and repeated redeposition. In addition, garnets underwent significant hypergene corrosion in the residual soil and subsequent dissolution under metasomatic conditions. As a result of such exogenous evolution, no trace of their primary morphological characters associated with the deep stage of morphogenesis remained on garnets. For this reason, it is impossible to quantify the degree of primary sources removal.

Euphorbiaceae is one of the largest family of flowering plants, in our study different species were collected from different localities of Mizoram, the collected specimens were studied and their morphological features noted. 34 genera of Euphorbiaceae s.l were used in the study. Cladistic analysis was performed in Mesquite software and Phenetic analysis was done in NTsys software. Both analyses produce a pictorial representation in a form of a tree; cladistic analysis produce phylogenetic tree (evolutionary relationship) while phenetic analysis produce phenogram (morphological relationship). The results of the aforementioned analyses were further analysed by total evidence technique and taxonomic congruence, a phylogenetic software PAUP is used for this purpose. The resultant trees were very different and comparison was done to find correlation between evolution and morphological characters. The research finds various correlation among characters like the number of locule in ovule, phyllanthoid branching and support the inclusion of genus like Breynia, Sauropus into Phyllanthus.
