Right coronary artery of the heart of a newborn Yorkshire pig

The study of the heart, as well as its blood supply, is of particular scientific interest in the field of veterinary and human morphology due to the widespread use of pigs as experimental animals in transplantology. Knowledge of the breed and age anatomical, topographic and morphometric characteristics of the coronary arteries of the heart will allow us to use the data obtained by us not only for experimental and scientific purposes, but also in veterinary practice for the prevention and treatment of pathologies of the cardiovascular system of pigs. Based on the foregoing, the purpose of our study is to study the anatomical, topographic and morphometric characteristics of the right coronary artery of the heart of newborn piglets of the Yorkshire breed at the age of one to three days.The material for the study was the corpses of newborn piglets aged one to three days, who fell after internal non-different diseases of unknown etiology. The cadaveric material was delivered to the Department of Animal Anatomy from private farms in the Leningrad Region. In total, ten corpses of newborn pigs of the Yorkshire breed were examined. The methods for the study were: fine anatomical preparation, morphometry using an Elitech electronic caliper with a division value of 0.02 mm, made in the USA and the manufacture of a corrosive preparation based on latex milk with subsequent processing sodium hydroxide. The processing of the obtained morphometric data was carried out in the Excel program.According to the results of the study, it was found that in newborn piglets of the Yorkshire breed at the age of one to three days, the right coronary artery has such main branches as the right diagonal and right subsinus arteries. The right coronary artery in the studied animals is involved in the blood supply to the wall and cavity of the right ventricle, the wall and cavity of the right atrium with its heart auricle, the interventricular septum, and also the right anterior surface of the wall of the left ventricle. It has been determined that the heart of newborn piglets of the Yorkshire breed has a uniform type of blood supply to the heart with a slight dominance of the right coronary artery over the left.

Right Coronary artery of the heart of Maine coon cat

The study of the arterial bed of the heart of small domestic animals is of high practical importance in veterinary practice and requires further development and study. The work was performed at the Department of Animal Anatomy, St. Petersburg State University of Veterinary Medicine. The material for the study was five corpses of Maine Coon cats, of which three cats (male) and two cats (females).The methods for the study were fine anatomical preparation and making casts of heart vessels using Flexstep latex milk. According to the results of the study, it was found that the right subsinus artery in a Maine Coon cat is poorly developed and does not participate in anastomosis with the branches of the left paraconal artery in the region of the apex of the heart. In the region of the coronary sulcus, the right anastomotic branch departs from the right coronary artery, which is involved in closing the collateral path of blood supply to the heart of the Maine Coon cat. The blood supply to the heart of a Maine Coon cat is due to the right and left coronary arteries, but the right coronary artery and its branches are less developed compared to the left, which confirms that this cat breed has a left-coronal type of blood supply.

ANATOMICAL AND TOPOGRAPHIC PATTERNS OF THE LEFT CORONARY ARTERY OF THE HEART OF A MAINE COON CAT

The heart is the central and regulatory organ of the cardiovascular system, the study of the morphology of its bloodstream in humane and veterinary medicine is an important aspect for further diagnosis, prevention and treatment of heart pathologies. In all studied species, the heart is supplied with blood by the right and left coronary arteries, which, according to the species and breed features of the structure, can differ in the degree of their development. The study of the main branches of the coronary arteries and branches of the first and second order, together with their functional significance in the blood supply of a particular structure of the heart, is a topical area in modern veterinary morphology. The purpose of the study is to study the anatomical and topographic patterns of the left coronary artery of the heart of a Maine Coon cat. The object for the study was the corpses of Maine Coon cats at the age of three to five years. In total, five corpses of animals were studied, of which three cats (male) and two cats (females). The following research methods were used: fine anatomical preparation and making casts of heart vessels using Flexstep latex milk. In the course of the study, it was found that the blood supply to the heart of a Maine Coon cat occurs due to the right and left coronary arteries, the latter of which is dominant, from which it follows that this breed of cats has a left-coronal type of blood supply. In the region of the coronary sulcus, anastomotic branches depart from the branches of the left coronary artery, thanks to which the collateral path of blood supply to the heart of the Maine Coon cat closes. The interventricular septum of the heart is supplied with blood by the interventricular branch extending from the left coronary artery.

Revisiting the vascularity of the keratinized gingiva in the maxillary esthetic zone

BackgroundThe active arterial-to-arterial collaterals are a significant factor in the prevention of ischemia and extensive tissue necrosis in the case of arterial blockage of various tissues. The present study investigates the mucogingival vasculature in the maxillary esthetic zone mucosa in human cadavers and functionally evaluates the area, which is supplied by the terminal arterioles, on the individual level.MethodsIn the human cadaver study, macroscopic arterial analyses of the anterior maxillary vestibule in 7 specimens were scrutinized by latex milk injection. The tracks of the mucosal branches in relation to the mucogingival junction were investigated. In the functional study, individual gingival blood flow (GBF) changes were measured by laser speckle contrast imaging (LSCI) in 31 young subjects with healthy gingiva before and during 30-s compressions. This was conducted with a ball-shaped condenser. The data was analyzed by the linear mixed model.ResultsThe vertically aligned branches of the superior labial artery (SLA) divided into small, slightly deviating sub-branches near the mucogingival junction. These arteries created collateral plexuses and supplied the attached gingiva. The compression of these branches resulted in ischemia coronally with significant individual variation. The ischemia was either apico-mesial, apico-distal, or straight apical to the compression. A significant correlation was found between the ischemic area and the magnitude of the decrease in GBF (r = 0.81, p < 0.001). In males, 77% of the subjects, and 50% of the female subjects had an ischemic response in either region. The horizontal extension of the ischemic area ranged between 0.26 mm and 8.76 mm. Males had significantly higher baseline GBF and larger ischemia than females. At the base of the papilla, significant restoration of GBF was observed during compression in males, but not in females.ConclusionThe arcade anastomoses formed by the small arteries in the keratinized gingiva of the upper esthetic zone explain the consequences of vertical incisions. The considerable individual variations in ischemic responses might be the reason for unexpected surgical outcomes in some cases. Furthermore, there is increasing evidence that men have different vascular reactivity and/or regulation of collateral circulation than women, which may affect wound healing.

In vitro studies on the degradation of common rubber waste material with the latex clearing protein (Lcp1VH2) of Gordonia polyisoprenivorans VH2.

The enzymatic degradation of the rubber polymer poly(cis-1,4-isoprene), e.g. by the latex clearing protein Lcp1VH2 of Gordonia polyisoprenivorans VH2 has been demonstrated with latex milk or pure isoprene-rubber particles, recently. Unfortunately, carbon black filled vulcanized rubber (CFVR) making the biggest part of worldwide rubber wastes, contains several harmful additives making microbial and enzymatic rubber degradation challenging. However, this study demonstrates the successful enzymatic cleavage of industrially produced CFVR. The formation of the cleavage products, oligo(cis-1,4-isoprenoids), from incubating CFVR particles with Lcp1VH2 was detected by HPLC-MS. Various organic solvents were tested to remove harmful or inhibiting additives like antioxidants to enhance product formation. The pretreatment of CFVR particles, especially with chloroform or cyclohexane, significantly improved the degradation. It was also demonstrated that reducing the particles size and thus increasing the enzymatically accessible surface area of the particles led to a strong acceleration of the degradation process. Furthermore, ATR-IR analyses showed that Lcp1VH2 led to the functionalization of the rubber particle surface with carbonyl groups by cleaving isoprene chains, still linked to the particle. Both, the oligo(cis-1,4-isoprenoids) as well as the functionalized rubber particles, are potentially important products, which can be reused as fine chemicals or as additives in rubber production. The present study, showing the enzymatic degradation of common CFVR for the first time, takes an important step towards a new way of rubber waste disposal and indicates the economic feasibility of an efficient and environmentally friendly recycling process by using the rubber oxygenase Lcp1VH2.

The topographic and systematic anatomy of the alpaca stomach.

The gastric anatomy of the alpaca (Vicugna pacos) is adapted to the physiological process of ruminating and the degradation of plant cell wall contents to a great extent. Most alpaca husbandries consist of only few animals and with the still increasing number of alpacas worldwide the number of persons who are responsible for these animals is increasing as well. Despite this, little research has been done with regard to the clinical anatomy of the stomach of alpacas. Six animals were used for dissection. The vascular system of two alpacas was injected with latex milk to illustrate the course of the blood supply to the viscera. One stomach was used to prepare formalin-fixed preparations. The stomach consisted of three compartments (C1-C3) and showed two sacculated areas in C1 and another comb-like system in C2. The compartments were lined by a smooth mucosa. Only the deep cells of C2 were lined by a papillated mucosa. The main blood supply was provided by the coeliac artery which was divided into the hepatic artery and the left gastric artery, supplying abdominal organs like liver, spleen, pancreas, and the initial part of the duodenum. Literature research on the llama stomach showed that the alpaca stomachs that were used resembled each other to a very large degree. The specific design of the stomach together with its related functions and physiological processes confirm that the evolution of Tylopoda and Ruminantia took place in parallel and not in homology.

Vascular survey of the maxillary vestibule and gingiva\u2014clinical impact on incision and flap design in periodontal and implant surgeries

ObjectivesCurrently, empirical clinical findings on the blood supply of the maxillary vestibule are not backed up with sufficient literature. The purpose of this study was to investigate the mucosal and periosteal vascular supply in the maxillary vestibule macroscopically and radiographically to improve surgical strategies and flap designs.Materials and methodsThirty head corpses were selected (9 dentate, 11 partially edentulous, 10 edentulous). Twenty-six corpses were injected by red latex milk and embalmed with Thiel solution. Four cadavers were prepared for corrosion casting. Arterial path and anastomoses in the maxillary vestibule of dentate, partially edentulous and edentulous ridges, were analyzed macroscopically and by computed tomography (CT).ResultsTransverse periosteomucosal anastomoses were detected in the posterior and esthetic zones of the maxillary vestibule. The buccal branches penetrated the interdental septum toward the palate. In the esthetic zone, superior labial artery (SLA) supplied the mucosa and the infraorbital artery (IOA) supplied the periosteum. Corrosion casting showed anastomoses between IOA and nasal septal branches. CT analysis revealed ipsilateral and contralateral anastomoses between SLA and IOA. In dentate ridges, mucosal star-shaped terminal branches were detected.ConclusionsThe macroscopic and radiographic vascular survey analysis revealed the anatomical background behind several clinically documented phenomena related to oral and periodontal surgeries.Clinical relevanceThis study permits clinicians to design less invasive flaps when releasing incisions in the maxillary vestibule during periodontal and implant surgeries. Our observations strongly point to the significance of an undamaged periosteum to prevent compromised flap revascularization and wound healing disturbances.

Arterial Blood Supply and Angiography of the Fore Foot in One- Humped Camel (Camelus dromederius)

The present study was conducted on eight fresh forelimbs to investigate a detailed anatomical description of the arterial blood supply in adult dromedary camel’s foot. Anatomical and angiographic techniques were used in order to give detailed data about the origin and pattern of distribution of these arteries. Moreover, this data serve other researchers in comparison with different animals. The specimens injected with red colored gum milk latex for anatomical dissection and urograffin injection for angiographic purposes throughout the median artery. The main arterial blood supply of camel’s digit was derived from common palmar digital artery, palmar metacarpal artery, in addition to smaller branches detached from the dorsal metacarpal artery.

Detection of Vascular Pathways of Oral Mucosa Influencing Soft- and Hard Tissue Surgeries by Latex Milk Injection.

In this methodological study, the purpose was to visualize the macroscopic vascular pathway of the oral mucosa. Corpses were injected and fixed with Thiel's solution for embalming to keep the natural color, fresh texture, and elasticity of the tissues. Latex milk injection is a technique used to stain blood vessels. A combination of Thiel's embalming method and latex milk injection allows surgeons to work on a raw specimen and identify the distribution and anastomosis of vessels macroscopically in the oral mucosa for flap/incision design in periodontal and maxillofacial surgeries. The latex milk contains radiopaque material that enables clinicians to visualize the pathway of the blood vessels radiographically. A step-by-step protocol is described for the correct adjustment of Thiel embalming and latex milk injection. The combined application of both methods allows the clinician to understand anatomical structures practically. As a result, proper incisions and flaps can be designed, which prevents neurovascular damage, intraoperative bleeding, and postoperative morbidity during patient surgery.

Analysis of blood supply in the hard palate and maxillary tuberosity-clinical implications for flap design and soft tissue graft harvesting (a human cadaver study).

The aim of the present study is to provide a detailed macroscopic mapping of the palatal and tuberal blood supply applying anatomical methods and studying specific anastomoses to bridge the gap between basic structural and empirical clinical knowledge. Ten cadavers (three dentate, seven edentulous) have been prepared for this study in the Department of Anatomy, Semmelweis University, Budapest, Hungary, and in the Department of Anatomy of the Medical University of Graz. All cadavers were fixed with Thiel's solution. For the macroscopic analysis of the blood vessels supplying the palatal mucosa, corrosion casting in four cadavers and latex milk injection in other six cadavers were performed. We recorded major- and secondary branches of the greater palatine artery (GPA) and its relation to the palatine spine, different anastomoses with the nasopalatine artery (NPA), and lesser palatal artery (LPA) as well as with contralateral branches of the GPA. Penetrating intraosseous branches at the premolar-canine area were also detected. In edentulous patients, the GPA developed a curvy pathway in the premolar area. The blood supply around the maxillary tuberosity was also presented. The combination of different staining methods has shed light to findings with relevance to palatal blood supply, offering a powerful tool for the design and execution of surgical interventions involving the hard palate. The present study provides clinicians with a good basis to understand the anatomical background of palatal and tuberal blood supply. This might enable clinicians to design optimized incision- and flap designs. As a result, the risk of intraoperative bleeding and postoperative wound healing complications related to impaired blood supply can be minimized.

Macroanatomic investigations on the course and distribution of the celiac artery in Hooded crow (Corvus cornix) with special reference to the arterial supply of the stomach

The aim of this study was to investigate the course and distribution of the celiacartery in Hooded crows and to extend our knowledge on the captured crows.Scarce information in the field of veterinary comparative anatomy and theavailable literature on the celiac artery and its distribution is provided. So, thepresent study tried to declare the confusion about the course and distributionof the celiac artery in the Hooded crows. Therefore, 10 apparently healthyHooded crows of different ages and sexes were captured. The birds wereanaesthetized by IM injection of 0.5 cc of 2% xylazine HCL (3 mg/kg). Coloredgum milk latex (60%) was then injected through the descending aorta. Then,specimens were subjected to fine dissection to demonstrate the origin, courseand distribution of the celiac artery. The celiac artery erupted laterally from theright face of the descending aorta opposite to the distance between the 5thand 6th vertebral rib, on a level with the junction of the esophagus and theproventriculus. It proceeded ventrally and slight caudally, where it gave off theesophageal artery after, 5 cm from its origin, the dorsal proventricular artery,splinc arteries and at the middle of spleen then bifurcated into left and rightbranches. The left branch of the celiac artery gave rise to right hepatic artery,ventral proventricular artery, pyloric branches, ventral gastric artery and thencontinued as the A. gastrica sinistra. The right branch of the celiac arteryreleased the caudal group of splenic arteries, A. gastrica dextra, then continuedas A. pancreaticoduodenalis.

Driving the photoluminescent and structural properties of X2-Y2SiO5 by varying the dopant Dy3+ concentration towards cool WLED applications

Dy3+ doped Y2SiO5 nanophosphors were synthesized by solution combustion technique using Calotropis gigantean milk latex and NaCl as fuel and flux respectively. Powder X-ray diffraction (PXRD) confirmed the formation of monoclinic X2-phase Y2SiO5 belonging to the phase group C2/c. Fourier transform infrared spectroscopy (FTIR) shows characteristic metal–oxygen (Y–O) vibration band at 721 cm−1. Transmission electron microscopic (TEM) and Scanning electron microscopic (SEM) morphological feature exhibits non-uniform almost spherical shaped nanosized particles. The photoluminescence (PL) emission peaks, recorded at 388 nm, showed radiative emissions at 483, 575 and 636 nm respectively. Judd–Ofelt (JO) analysis was carried out to estimate the radiative (AR) properties, radiative life time (τR), branching ratio (βR) and stimulated emission crossection (σλp). The CIE and CCT was estimated using McCamy empirical formula. In the beginning, the CIE co-ordinate values were lying in the light blue region. However, with increase in Dy3+ concentration the values shifted towards white region. CCT value was found to be ∼6984 K. Therefore, Y2SiO5:Dy3+ (9 mol%) can be used for cool day light and WLED applications.

Arterial supply of the stomach of the Egyptian native goat

Objective : This study was conducted to investigate the origin, course and distribution of the arteries supplying the stomach of the goat which is of extreme clinical importance for surgeon during caprine rumenotomy. Materials and methods: Fifteen adult goats were used in this study to demonstrate the arterial supply of the stomach by injection of the thoracic aorta with red gum milk latex after general anesthesia and slaughtering of the animals. Gross dissection of the arteries of the stomach was done to detect the origin, course and distribution of these arteries. Results : The study revealed that the rumen was richly supplied by the right and left ruminal arteries as well as ruminal branches from the reticular artery. The reticulum was supplied with reticular branches of reticular and accessory reticular arteries. The omasum was vascularized by omasal branches of the left gastric artery. While the abomasum received its entire arterial supply from abomasal branches of the left gastric, left gastroepiploic, right gastric and right gastroepiploic arteries. Conclusion : The stomach of the goat receives its arterial supply from the branches of the right ruminal, left ruminal, reticular, left gastric and hepatic arteries. Rumenotomy could be done in the left aspect of the dorsal ruminal sac, between the area of anastomoses of the terminal branches of the left and right ruminal arteries as the blood supply was minimal, so that bleeding will be low. http://doi.org/10.5455/javar.2017.d194

Some Morphological and Radiographical Studies on the Flexor Aspect Hind Foot in Buffalo

The general morphological features of the digital flexor tendons and the synovial sheaths associated with them were studied on thirteen hind feet of adult buffalo, after the injection of the sheath either by colored gum milk latex or by a radiopaque emulsion. Dissection has revealed that, the terminal tendons of both the superficial and deep digital flexor muscles enclosed in a complex common digital sheath. The more suitable sites for injection in the synovial sheaths of the flexor tendons were determined. Also this study extends to include the middle interosseous muscle and its connection with adjacent structures. Computed tomography scan were used to identify the bony and soft tissue structures of the metatarsus and digits. The obtained results were discussed with those recorded in other domestic animals.

Lateral Branches of the Testicular Artery Affect Testicular Shape in Adult Stallions

The objective of this study was to investigate the arterial patterns of the stallion testis in relation to testicular shape. Two hundred and fifty-one stallion testes were evaluated for the presence of the lateral branches of the testicular artery. Seven specimens had their testicular arteries filled with latex milk, fixed in 70% alcohol, and dissected. Two hundred six specimens (82%) had a single testicular artery and no lateral branches; 39 testes (16%) had one lateral branch of the testicular artery; and six testes (2%) had two lateral branches of the testicular artery each. The lateral branches of the testicular artery obtained from the adult stallions, more than 5 years old, were associated with distinct lateral bulging, giving them a pear-like shape, whereas similar vascular pattern in young colts, less than 1 year old, did not cause similar shape change. Five distinct patterns of the branching of the testicular artery were determined. We concluded that the lateral branches of the testicular artery are present in approximately 20% of stallion testes. This anatomic pattern is associated with a lateral bulge that develops slowly over several years and is associated with a change in testicular shape from an ellipsoid in colts to a pear-like shape in adult stallions.

Calotropis mediated hydrothermal route for the synthesis of Eu3+ activated La(OH)3 and La2O3 red phosphors

The study details a green-mediated hydrothermal route for the synthesis of Eu3+ activated La(OH)3 and La2O3 nanophosphors using Calotropis milk latex (CML) as a surfactant. The functionalization of as-formed La (OH)3: Eu3+ (10 ml, 1, 5, 9, 11 mol%), calcined La2O3: Eu3+ (2–12 ml, 9 mol%) and La2O3: Eu3+ (10 ml, 1–11 mol%) nanophosphors was investigated through PXRD, FTIR, SEM, TEM and photoluminescence (PL) studies. From the surface morphology, it was noticed that the CML/Eu3+ concentration showed tremendous potential in the self-assembly process and has been utilized as a soft template for the engineering of ordered nanostructures. The energy band gap of calcined La2O3: Eu3+ (10 ml, 1–11 mol%) was found to decrease from 4.68 to 3.91 eV. The PL intensities of transitions between different J levels depend on the symmetry of the local environment of Eu3+ activators. The high ratio of intensity of (5D0 → 7F2) and (5D0 → 7F1) provides the conclusion that the Eu3+ ion occupies a site with a low symmetry and without an inversion centre. La (OH)3: Eu3+ (10 ml, 9 mol%) and La2O3: Eu3+ (10 ml, 9 mol%) nanophosphors show an intense red emission with CIE coordinates (0.56, 0.43) and (0.58, 0.41) respectively. The correlated color temperature (1893 K, 1786 K) was within the range of vertical daylight. The present study successfully demonstrates biotemplate-mediated green synthesis of hexagonal La(OH)3: Eu3+ and La2O3: Eu3+ nanophosphors for display applications.

Gross morphological and angioarchitectural study of the orol cavity in the egyptian domesticated ducks (Anas platy rhynchos domesticus)

The morphology and Angioarchitecture of the Oro-pharynx in the Egyptian domesticated ducks were described. The present work was carried out on ten apparently healthy domestic ducks of different ages and sexes. The ducks were anaesthetized, and then injected through the mandibular artery and cranial vena cava by colored red and blue gum milk latex (60%), respectively to study the arterial supply and venous drainage. Three specimens were used for the morphological studies; the oral cavity has palatum and lingua. Three birds were prepared to study the arterial supply; the mandibular artery is the main arterial supply of the oral cavity and represents the direct continuation of the external carotid artery. While the remaining four specimens applied to study the venous drainage; the two jagular veins terminated in the oral cavity by forming interjagular anastomosis. The obtained results were photographed, described and discussed with those given by previous authors who performed earlier studies in other species of birds. The nomenclature used was adopted according to the Nomina Anatomica Avium (1993).

Calotropis procera mediated combustion synthesis of ZnAl2O4:Cr3+ nanophosphors: Structural and luminescence studies

ZnAl2O4:Cr3+ nanophosphors were synthesized for the first time by a simple and environment friendly route using Calotropis procera milk latex as fuel. The structural and surface morphological studies were carried out using powder X-ray diffraction (PXRD), scanning electron microscopy and transmission electron microscopy techniques. The photoluminescence (PL) properties of ZnAl2O4:Cr3+ as a function of dopant concentration and calcination temperature was studied in detail. The PXRD patterns and Rietveld confinement confirmed the cubic crystal system with space group Fd-3m. The crystallite size estimated from Scherrer’s and W–H plots was found to be in the range of 16–26nm. The PL spectrum shows an intense peak at ∼688 and ∼699nm assigned to spin – forbidden 2Eg→4A2g transition of Cr3+ ions. The PL measurements for two excitations (∼410 and 527nm) and with respect to calcination temperature indicated no significant change in the shape and position of emission peak except PL intensity. The CIE chromaticity coordinates lies well within the white region. Thermoluminescence (TL) studies revealed well resolved glow peak at ∼212°C with a small shoulder at 188 and 233°C. The glow peak intensity at ∼212°C increases linearly with γ-dose which suggest ZnAl2O4:Cr3+ is suitable candidate for radiation dosimetric applications. The activation energy (E in eV), order of kinetics (b) and Frequency factor (s) were estimated using glow peak shape method.
