The objective of this study was to determine the effects of some antioxidant vitamins and trace elements on some metabolic and postpartum reproductive profiles in dairy cows during transition period. In the study, altogether 20 clinically healthy Brown Swiss dairy cows (aged 4-5 years-old) under the same management and feeding conditions in periparturient period were used. The animals were divided into two equal groups: control (C) and treatment (T) group (n=10 for each group). Vitamins (A, D, E) and trace elements (Cu, Mn, Se, Zn) were administered intramuscularly into the cows of the T group, while isotonic saline, as placebo, was injected subcutaneously into those in the C group...

An evaluation of blood chemistry profile in relation to specific stages of livestock cycle can help better understand variations in physiological conditions in order to adjust management systems to animal needs. In addition to basal hematological investigation, the acid-base balance and blood gases are essential tools in evaluating metabolism in calves. The relationship between blood gas parameters, diet and growth should be further investigated. The aim of this study was to evaluate changes in acid-base status, blood gases, serum chemistry and hematological parameters in veal calves at different periods of livestock cycle...

HYPOTHESIS: Internal jugular vein (IJV) compression before blast injury will lead to reduced risk of traumatic hearing injury following exposure to a blast injury. BACKGROUND: IJV compression and its effects on not only intracranial, but also intracochlear pressure may potentiate blast induced hearing injury, therefore, precluding its use as a prophylactic therapy for blast induced traumatic brain injury. METHODS: Twenty Sprague Dawley rats were exposed to a 17...

BACKGROUND: The continuous monitoring of vital parameters and subsequent therapy belong to the core duties of anaesthetists during acute trauma resuscitation in the trauma room. Important procedures may include placement of arterial lines and central venous catheters (CVCs). Knowledge of indication, performance and localization of invasive catheterisation of trauma care in Germany is scarce. METHODS: After approval of the German Society of Anaesthesiology and Intensive Care Medicine we conducted an online survey about arterial and central venous catheterisation of severely injured patients with consideration of common practice used by anaesthetists in German trauma rooms...

A primary focus of this research was to explore the activation process and mechanism of decitabine (5-aza-2'-deoxycytidine, DAC) prodrug. Recently, it has been reported that biphenyl hydrolase-like protein (BPHL) can play an important role in the activation of some amino acid nucleoside prodrugs with a general preference for hydrophobic amino acids and 5'-esters. Therefore, we put forward a bold hypothesis that this novel enzyme may be primarily responsible for the activation process of DAC prodrug as well...

BACKGROUND: Recently, we established a new rat model of venous arterialization by grafting the jugular vein into carotid arteries. In many respects, the morphological features of this murine vascular graft model resemble those of human venous bypass graft diseases. Using this model, we studied nanoparticles that mediated the arresten gene to inhibit the neointimal formation of vein grafts. METHODS: Thirty healthy Wistar female rats were randomly divided into three groups...

The oxytocin (OXT) system is functionally linked to the HPA axis in a reciprocal and complex manner. Certain stressors are known to cause the simultaneous release of OXT and adrenocorticotrophic hormone (ACTH) followed by corticosterone (CORT). Furthermore, brain OXT attenuates ACTH and CORT responses. Although there are some indications of CORT influencing OXT neurotransmission, specific effects of CORT on neurohypophyseal or intra-hypothalamic release of OXT have not been studied in detail. In the present set of experiments, adult male rats were adrenalectomized (ADX) or sham-operated and fitted with a jugular vein catheter and/or microdialysis probe targeting the hypothalamic paraventricular nucleus (PVN)...

A new method for covering the internal jugular vein and carotid artery after exposure of the cervical vascular axis subsequent to neck dissection is presented. To cover the most caudal part of the vascular axis, a platysma coli muscle flap is harvested from its most medial and inferior part of the neck in a caudally based fashion and is slightly rotated posteriorly up to 45°. In addition, a superiorly based sternocleidomastoid muscle flap involving the posterior half of the muscle after detachment of the clavicle head is harvested and rotated 45° anteriorly to cover the upper two thirds of the vascular axis...

A 60-year-old man presented with a 10-month history of of stereotypical spells characterized by vertigo, tinnitus, blurred vision, left hemibody numbness, and occasional syncope, precipitated by turning his head leftwards. Cerebral angiography and CT angiography of the head and neck with provocative maneuvers did not demonstrate vertebral artery narrowing. However, there was narrowing of the left internal jugular vein due to extrinsic compression from the sternocleidomastoid with leftward head rotation in the setting of hypoplasia of the right internal jugular vein...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

Pulsatile Tinnitus (PT) is a pulse-synchronous sound heard in the absence of an external source. PT is often related to abnormal flow in vascular structures near the cochlea. One vascular territory implicated in PT is the internal jugular vein (IJV). Using computational fluid dynamics (CFD) based on patient-specific Magnetic Resonance Imaging (MRI), we investigated the flow within the IJV of seven subjects, four symptomatic and three asymptomatic of PT. We found that there were two extreme anatomic types classified by the shape and position of the jugular bulbs: elevated and rounded...

BACKGROUND: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is an ever-emerging method of managing respiratory failure in patients who are refractory to conventional mechanical ventilatory support. An increasingly common method of cannulation involves placement of a bicaval dual-lumen, single cannula via the right internal jugular (IJ) vein. Thrombus in this vein has been considered a contraindication for cannula placement. CASE REPORT: A 45-year-old Hispanic male presented with bleomycin-induced respiratory failure resulting in acute respiratory distress syndrome (ARDS)...

AIMS: Central Sleep Apnea Syndrome, correlated with the occurrence of heart failure, is characterized by periods of insufficient ventilation during sleep. This acute study in 15 patients aims to map the venous system and determine, if diaphragmatic movement can be achieved by phrenic nerve stimulation at various locations within the venous system. METHODS: Subjects underwent a scheduled catheter ablation procedure. During the procedural waiting time, one multi-electrode EP catheter was subsequently placed at the the superior and inferior vena cava and the junctions of the left jugular and left brachiocephalic vein and right jugular and right brachiocephalic vein, for phrenic nerve stimulation (1-2 seconds ON / 2-3 seconds OFF, 40 Hz, pulse width 210 μs)...

Experimental setups for physiological research, in which acute operative interventions need to be performed, can require inclusion of general anesthesia (GA), which may interfere or confound with the effects of the experimental factors of interest on measured variables. It was recently shown that the most commonly used sedatives/anesthetics in pigs (e.g., ketamine, xylazine, azaperone) affect physiological responses and thus the primary metabolic readouts have the potential to be confounded. To extend the search for a physiologically-friendly anesthesia regime for such studies, we investigated effects of GA induced by propofol (Prop) or pentobarbital (Pent) or propofol plus isoflurane (Prop + Isof) on plasma concentrations of commonly measured metabolites and hormones...
