Egretta Garzetta

The egretta bird (Egretta zegretta) has a body size of 55-65 centimeters, it is wings stretches 88-106 centimeters, has a long neck and typical neck like the letter “S”. The purpose of this research is to find out the anatomical structure of trabeculae in the egretta bird. To find out the trebeculae in the egretta bird, meat on the neck cleaned. Then, each bone segment is cut and sanded on the ventral and lateral part until spongiosa tissue (trabeculae) is seen, and transversely cut. The observation result show that on the C6 bone segment has a trabecular structure more dense comepared to the structure of the trabelucae in other bone segments. That is because in the C6 bone segment gets pressure from top and bottom, so C6 bone segment stronger.

The Difference

Reptile tails have a unique function as self defense, autotomy, and maintaining balance while in nature. There are several species that do not have an autotomy function, these species include Estuary Crocodile (Crocodylus porosus), Java Chameleon (Bronchocela jubata), and Klarap (Draco volans). The species is a reptile class that uses its tail with different functions. Differences in function in the tail can be caused by differences in anatomical structure, morphology, and behavioral adaptations that are owned by each species. With the differences in each species, this study aims to get a comparative picture of the caudal vertebrae (coccyx) anatomy of species of estuary crocodile (Crocodylus porosus), java chameleon (Bronchocela jubata), and klarap (Draco volans) so that anatomical comparison can be seen in each species that affects the difference in tail function. The method used in this study is morphological observation with boiled method, X-Ray method, and Alizarin Red's and Alcian Blue staining methods. Research that has been conducted shows that the anatomical structure of caudal vertebrae (coccyx) in estuary crocodile species has a larger bone structure than the bone structure of java chameleon and klarap. The anatomical structure of caudal vertebrae (coccyx) in klarap has a smaller bone structure than estuary crocodile and java chameleon. The anatomical structure of caudal vertebrae (coccyx) in java chameleon species has a longer bone structure than its body length. Caudal vertebrae of these three species do not have tail fracture fields.

Abstract Alpinia warburgii is a species of the Zingiberaceae family native to Sulawesi. This study aims to characterize the plant morphology; analyze the anatomical structure, histochemical localization, and secretory cell structure of the rhizome; also discuss the potential and conservation effort of the species. Anatomical study and histochemical tests were observed microscopically using the fresh preparation method and wet mounted slide. Histochemical tests carried out include starch, protein, lipid, tannin, alkaloid, and flavonoid. This study is considered the first report of histochemical tests on A. warburgii. The main morphological characteristics of A. warburgii are perennial herbaceous; inflorescence terminal and raceme; flowers white, labellum obovate with red lines in the middle, and flanked by light green edges; fruit globose, green when young and yellow when ripe. The rhizome anatomical structure comprises the epidermis, endodermis, hypodermis, parenchyma, cortex, and vascular bundles, classified as closed collateral type. Histochemical tests showed positive localization for starch, protein, alkaloids, flavonoids, and tannins. The density of flavonoids secretory cells is higher than tannins and alkaloids, which indicates its potential as medicine to be associated with antioxidant, antimicrobial, antiinflammation, and anticancer. In addition to in-situ, ex-situ conservation effort through propagation is also important to maintain the species.

Bamboo is known as fast-growing species that could be derived into various products. However, bamboo is suspectible to the wood destroying organisms.  Preservation is one way to improve the service life of bamboo. This study aimed to analyze the effect of differences in anatomical structures of betung bamboo (Dendrocalamus asper Backer) and andong bamboo (Gigantochloa pseudoarundinaceae (Steudel) Widjaja), and the effect of pressure on the flow time and retention of entiblu preservative in the Boucherie method. Bamboo stems with diameters of 10-14 cm were cut in 1; 1,5; 2; and 2,5 m lengths. The bamboo stems with moisture content of around 30% were preserved by 5% of entiblu preservative solution. The data observed were the flow time of the preservative entiblu solution from base of the stem until dripping on the top of the bamboo culm, and the retention of preservative. The anatomical structure of the bamboo trunk before preserving was also observed. The results showed that the average flow times in andong bamboo and betung bamboo were 37.75 minutes and 41.50 minutes, respectively. The average retention of entiblu solution on andong bamboo was 3.49 kg/m³ and on betung bamboo was 3.60 kg/m³.

Oxalate Crystals

The features of the anatomical structure of Salsola arbuscula Pall., S. tragus L., S. paulsenii Litv. are presented. It is noted that the leaf blades of the studied species belong to the salsoloid type. The mesophyll of the leaf is centric. The hypoderma plays the role of the water-bearing parenchyma. In the water-bearing parenchyma of S. tragus and S.paulsenii calcium oxalate crystals have been found. In the central part of the leaf there is a single conducting beam of thecollateral type in all species. A characteristic feature in the anatomical study of the stem of S. tragus is the peculiarity ofthe collenchyma, which lies only in the area of protrusions and forms up to 7 layers of cells. The general features of theorganization of the studied species are the similarity in the succulent structure of the leaf blade, which causes large-cellwater-bearing parenchyma and the rounded shape of the cells in the three studied species of saltwort.

First Time

The purpose of this study consisted in the identification of the macroscopic and microscopic characters of the vegetative and reproductive organs of Bryonia alba L., by the analysis of vegetal material, both integral and as powder. Optical microscopy was used to reveal the anatomical structure of the vegetative (root, stem, tendrils, leaves) and reproductive (ovary, male flower petals) organs. Histo-anatomical details were highlighted by coloration with an original combination of reagents for the double coloration of cellulose and lignin. Scanning electronic microscopy (SEM) and stereomicroscopy led to the elucidation of the structure of tector and secretory trichomes on the inferior epidermis of the leaf. Micrographic analysis of the powder obtained from aerial parts revealed segments of each organ (e.g. stomata, trichomes) and confirmed furthermore the results obtained by the histo-anatomical studies. Sections achieved through vegetative organs reveal typical anatomical structures: a transition to the secondary structure for the root, a typical dicotyledons’ structure with bicollateral vascular bundles for the stem, a bifacial structure of the leaf and stem-like structures for the tendrils and petioles, which prove they are metamorphosis of the stem. Anatomical structure of reproductive organs was performed hereby for the first time and revealed a typical anatomical structure for the 3-lodged ovary and a leaf-like structure of the male flower petal. Some of the results obtained confirm existing data from the scientific literature and additional information have been provided, outlining features that were not previously reported, such as SEM analysis of the leaf trichomes and histo-anatomical structure of the reproductive organs.

Care Situation

Abstract. We investigated the association between the education of informal caregivers’ (IC) and their physical and mental burden. We hypothesized that better-educated IC would have more resources available to manage the care situation and as a result show lower perceived burden. We conducted a population survey of 6,087 German residents aged 18+ years, 966 of whom reported to be IC. Results show that IC felt more often mentally than physically burdened. In the multivariate analyses, higher-educated IC did not have lower odds of feeling physically burdened than lower-educated IC, though they did have increased odds of feeling mentally burdened. The higher perceived mental burden of higher-educated IC may be related to fear of loss of self-fulfilment and autonomy. Support services should consider the mental burden of higher-educated IC and tailor their interventions accordingly.
