Abstract:

The appearance and preservation of the teat end - ostium seu orificum papillae, is an important factor in preventing the penetration of mastitis agents into the udders of cow. The diseases of cow udder are of complex nature and are among the most expensive diseases in dairy cows. We took the udder of holstein-friesian cows that were excluded from production for different etiologic reasons, in order to monitor changes in the orificum papillae and stratum corneum ducuts papillaris.

Abstract:

Ductus papillaris presents the frontline of defense of the mammary gland against the penetration of microorganisms into the milk cystern and the mammary gland parenchyma. The specific structure of ductus papillaris is in the stratum corneum which lines the ductus papillaris. It is a fine layer similar to wax of various thickness. The thickness of the stratum corneum depends on the age and breed of the animal, as well as on the number of past lactation periods. The stratum corneum or the keratin layer of the ductus papillaris has a bacteriostatic and bactericidal effect and prevents the ascende

Abstract:

Pathomorphological changes in the mammary glands are usually caused by the interaction of macroorganism, microorganism and the environment. A very important processs during intramammary infection is the penetration of microorganisms in a tank papilla. In the mammary gland, there are several mechanisms to prevent penetration of bacteria into the mammary gland. The first line of defence against penetration of pathogens into the mammary gland is <em>ductus papillaris</em>. The interior of the <em>ductus papillaris</em> filled with similar wax, which contains long-chain fatty acids and basic prote

The objectives of the present study were to describe specific anatomical structures of the dromedary udder. Eighty-six dromedary udders were examined, taking morphological measurements and producing injection casts using resin, gelatin, and paraffin. The udder of the dromedaries consists of four quarters. The shape of the udders and teats varies considerably between animals and is influenced by age, breeding, and lactation status. The most frequently found udder form was the globular udder (48.8%) and the most common teat form in this study was the funnel teat (44.2%). The most common teat tip

Five patients with papillary adenocarcinoma of the common bile duct (CBD) are described. These are rare tumors and make up 5% of all malignant tumors of the biliary tract. The symptoms and signs at the time of initial diagnosis resemble benign obstructive lesions of the bile ducts. The tumor is soft, less invasive to adjacent tissues and tends to grow into the lumen. The early onset of the symptoms results in early intervention, with a better prognosis. Two of our patients are doing well after two and four years, where as three others were readmitted with recurrent disease.

Abstract:

Papillary collecting duct tubules were prepared in gram quantities from the papillae of dog and pig kidneys. Measurements of substrate and oxygen utilizations by these tubules under both aerobic and anaerobic conditions showed the potential for both glycolysis and oxidative phosphorylation. Oxygen is not necessary to maintain a normal adenosine 5′-triphosphate concentration, but oxidative phosphorylation contributes to more than 65% of the metabolism under aerobic conditions in the two species. Both phosphorus-31 and proton nuclear magnetic resonance spectra recorded from extracts of dog corte

Abstract A 10-month-old female child with failure to thrive was diagnosed to have a large atrial septal defect (ASD) with deficient rims and large patent ductus arteriosus (PDA) and was referred for management. Echocardiography showed normal left ventricular (LV) function with dilated right atrium and right ventricle; the only suspicious finding was that of the hyperechoic papillary muscle. After the PDA ligation, the ASD was closed with an autologous pericardial patch when the aortic cross-clamp was released, the rhythm returned and trans-oesophageal echocardiography showed severe LV dysfunct

Abstract:

Choledochal cysts, congenital segmental dilations of the common bile duct, have been reported in few cats, and histologic characterization is lacking. A 20-mo-old spayed female domestic shorthair cat was presented because of vomiting and weight loss. There was progressive elevation of liver enzyme activity (ALT > ALP, GGT) and hyperbilirubinemia. Diagnostic imaging identified focal cystic dilation of the common bile duct, dilation and tortuosity of adjacent hepatic ducts, and a prominent duodenal papilla. A choledochal cyst was suspected, and the animal was euthanized. On postmortem examina

Abstract:

ObjectivePancreatic cancer can arise from precursor lesions called intraductal papillary mucinous neoplasms (IPMN), which are characterised by cysts containing papillae and mucus-producing cells. The high frequency of KRAS mutations in IPMN and histological analyses suggest that oncogenic KRAS drives IPMN development from pancreatic duct cells. However, induction of Kras mutation in ductal cells is not sufficient to generate IPMN, and formal proof of a ductal origin of IPMN is still missing. Here we explore whether combining oncogenic KrasG12D mutation with an additional gene mutation known to

SUMMARY The udders and teats of cows were examined by brightness mode (B-mode) ultrasonography. A 5-MHz linear array transducer and a 5-MHz or 10-MHz mechanical sector transducer were used in the examinations. In lactating animals, the teat sinus, gland sinus, and lactiferous ducts were imaged easily. The scans also allowed visualization of the layers of the teat wall. The annular fold and the folding of the mucosa at the junction of the teat sinus and the papillary duct were seen best with the 5-MHz and 10-MHz mechanical sector transducers.

Abstract:

323 Background: Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis due to late detection, aggressive biology and resistance to chemotherapy. Markers for early detection of PDAC and mediators of chemoresistance are poorly understood. GRP78 is a major endoplasmic reticulum (ER) chaperone protein critical for protein quality control of the ER. Increased GRP78 expression promotes in vitro cancer cell survival, progression, and chemoresistance. This study aims to examine expression of GRP78 protein in PDAC and intraductal papillary mucinous neoplasm (IPMN) compared to normal pancreatic du

Abstract:

There are several types of microvasculature supplying neoplasms: “newly formed blood vessels” (neoangiogenesis), which are a component of the tumor microenvironment (TME) of invasive carcinoma with wound healing-like reaction; and “pre-existing blood vessels”, which are used as tumor-supplying vessels by neoplasms (co-option vessels) and are likely to develop in hypervascularized organs. We herein review the microvasculature of neoplasms of biliary tract with reference to pre-existing vessels and vessel co-options.
