Cymbopogon citratus showing nematicidal activity against Heligmosomoides polygyrus bakeri.

This paper describes a novel in vivo study of Cymbopogon citratus (lemon grass) to assess its anthelmintic activity. To this end, C57BL/6 mice were separated into three groups: G1: uninfected; G2: negative control infected with Heligmosomoides polygyrus bakeri and administered with 3% dimethyl sulfoxide (DMSO); and G3: infected with H. polygyrus bakeri and treated with C.

Ileocecal Valve Metastasis Inducing Cecal Volvulus in a Patient With Lobular Breast Cancer: A Rare Cause of Bowel Obstruction.

Invasive lobular carcinoma (ILC) is the second most prevalent form of invasive breast cancer. Characterized by its insidious growth and distinctive histopathological features, ILC often presents with a less predictable metastatic pattern, including potential invasion of the gastrointestinal tract. This report presents the case of a patient with ILC who developed ileocecal valve metastasis leading to cecal volvulus, a rare but critical complication.

Hemopneumothorax Secondary to Pleural Endometriosis in a Woman of Childbearing Age: A Rare Presentation.

Pleural endometriosis is a rare condition characterized by the presence of endometrial tissue outside the uterus, involving the pleura. This atypical condition can be asymptomatic or cause respiratory symptoms such as chest pain, dyspnea, and hemothorax. We present a clinical case of a 32-year-old woman who presented to the emergency room with hemothorax due to pleural endometriosis.

Intraoperative thermal mapping of mammary tumors in dogs.

In this study, videothermometry's application in detecting mammary tumors in dogs is explored in-depth. The research hypothesizes that this technique can effectively identify cancerous tissues during surgery by analyzing thermal patterns. The methodology involved comparing thermal imaging results from dogs with palpable mammary nodules against a control group, focusing on capturing real-time thermal patterns.

Pathological changes by spirorchiid eggs in hawksbill sea turtle (Eretmochelys imbricata) stranded off brazilian coast.

Eretmochelys imbricata (hawksbill turtle) is classified as a critically endangered species at world level; in Brazil, it is listed among the threatened species. Spirorchiids are parasites of the circulatory system of chelonians which may cause serious lesions in the various tissues of the host due to deposition of eggs in the bloodstream. In this context, the aim of the present study was to describe the pathology caused by spirorchiid eggs in E.

A new haemosporidian parasite from the Red-legged Seriema (Cariamiformes, Cariamidae).

Haemoproteids (Haemosporida, Haemoproteidae) are a diverse group of avian blood parasites that are transmitted by hematophagous dipterans. In this study, we describe sp. nov.

Modeling of Acute Pulmonary Arterial Hypertension in Pigs Using a Stable Thromboxane A Analogue (U46619): Dose Adjustment and Assessment of Hemodynamic Reactions.

U46619, a synthetic analogue of thromboxane A2 was used for modeling acute stable and reversible pulmonary arterial hypertension. Administration of U46619 in high doses led to vascular collapse and inhibition of cardiac function. The doses of U46619 were empirically selected that allow attaining the target level of pulmonary hypertension without systemic hemodynamic disturbances.

Perivascular Innervation of the Pulmonary Artery in Human and Swine: A Comparative Study for the Development of an Experimental Model of Denervation.

For studying the possibility of using catheter denervation of the pulmonary artery for the treatment of pulmonary hypertension, large animals, such as pigs, are more suitable, because the diameter of the pulmonary artery in this case allows manipulation of the ablation catheter. The study of the perivascular adipose tissue of the trunk and bifurcation of the pulmonary artery in humans and pigs revealed differences in the density and diameter of nerve fibers, but their depth did not differ. Immunohistochemical analysis with different markers of the autonomic nervous system receptors revealed similar receptor profile in human and pigs, though the expression of all studied markers in pigs was less pronounced than in humans.

First Report of Looss 1899 (Digenea: Pronocephalidae) in a Hawksbill Turtle - . Found in Brazilian Coast.

Looss 1899 (Digenea: Pronocephalidae) is a parasite exclusive to sea turtles, having been described in the green turtle () in Egypt, the USA, Panama, Costa Rica and Brazil as well as the olive ridley turtle () in Brazil. The present note describes the first occurrence of in a hawksbill turtle () found on the coast of Brazil.

Earthworm species in no-tillage agroecosystems and native Atlantic forests in Western Paraná, Brazil.

Earthworm populations often increase with the adoption of no-tillage (NT) practices, but few studies have evaluated earthworm diversity in these agroecosystems. In the present study we assessed earthworm species richness in 40 sites under NT and six native Atlantic forest fragments in Western Paraná, Southern Brazil. At each site earthworms were sampled quantitatively (n=5) and qualitatively (n=5), by handsorting soil monoliths (20 x 20 cm width x 20 cm depth), totaling 460 samples overall.

First Report of Goldberger and Crane, 1911 (Digenea, Dicrocoeliidae) from (Illiger, 1815) (Carnivora, Canidae) and Pathological Findings.

, the largest South American canid, is a native species of the Brazilian cerrado. The present study is aimed to report the occurrence of the trematode, , in the liver of a new host, , and to describe its morphology and pathology. One individual was necropsied and examined for the presence of parasites.

Multiple cavitary pulmonary nodules in association with pyoderma gangrenosum: case report.

Pyoderma gangrenosum is a rare neutrophilic disease of unknown origin that is associated with systemic diseases in 50% of cases. It is characterized by erythematous-violaceous nodular lesions that quickly progress to painful ulcers, with undermined edges, necrotic-hemorrhagic, varying in size and depth, located mainly in the lower limbs. Extracutaneous locations of pyoderma gangrenosum are rare, usually involving the lungs; the main differential diagnosis in these cases is Wegener granulomatosis.
