Delottococcus aberiae De Lotto (Hemiptera: Pseudococcidae) is the latest exotic mealybug species introduced in citrus in the Mediterranean basin. It causes severe distortion and size reduction on developing fruits. Due to its first interaction with citrus, D. aberiae economic thresholds are still unknown for this crop and the current Integrated Pest Management programs have been disrupted. The objectives of this study were to determine the aggregation patterns of D. aberiae in citrus, develop an efficient sampling plan to assess its population density, and calculate its Economic and Economic Environmental Injury Levels (EIL and EEIL, respectively)...

INTRODUCTION: The evolution of Natural Orifice Translumenal Endoscopic Surgery® (NOTES®) represents a case study in surgical procedural evolution. Beginning in 2004 with preclinical feasibility studies, and followed by the creation of the NOSCAR® collaboration between The Society of American Gastrointestinal and Endoscopic Surgeons and the American Society for Gastrointestinal Endoscopy, procedural development followed a stepwise incremental pathway. The work of this consortium has included white paper analyses, obtaining outside independent funding for basic science and procedural development, and, ultimately, the initiation of a prospective randomized clinical trial comparing NOTES® cholecystectomy as an alternative procedure to laparoscopic cholecystectomy...

Myocardial infarction (MI) is a common cardiovascular disease with high mortality. The aim of the present study was to determine the biological role of miR-145 in MI rats and hypoxia-injured cardiomyocytes and to elucidate the potential mechanism. MI rats were induced by left anterior descending artery (LAD) ligation. qRT-PCR and western blot analysis were performed to determine the mRNA and protein levels, respectively. Compared with sham group, miR-145 levels in MI group were significantly decreased. We observed that lentivirus-mediated overexpression of miR-145 significantly improves cardiac function, reduces infarcted tissue size and prevents post-infarction induced apoptosis in rats after MI...

The shoulder is the most frequently dislocated joint in the body due to a larger range of motion and a small area of articulation between the humeral and glenoid surfaces. Traumatic shoulder dislocations, especially those associated with injury to the labroligamentous or bony stabilizers of the joint, lead to further reduction of articular surface contact with resultant glenohumeral instability and recurrent shoulder dislocations. Imaging plays an increasingly important role in the preoperative evaluation of patients with traumatic shoulder instability by evaluating glenohumeral bone loss (uni- or bipolar), assessing soft tissue injuries and identifying patients at risk of postoperative recurrence...

INTRODUCTION: Glenohumeral dislocation (GHD) is frequent, but traumatic posterior glenohumeral dislocation (TPGHD) is rare, with an incidence of 1-4% of all GHD. The diagnosis is a challenge: sometimes, it can be omitted due to incorrect diagnosis, absence of consideration in the differential diagnosis, suboptimal radiographic evaluation and an absence of characteristic signs and symptoms; missed diagnosis reaches 60-79% and the diagnosis can delay from 24 hours to a year. OBJECTIVE: To transmit previous experiences to provide support for better diagnosing TPGHD, favoring appropriate attention...

Extensive research over the last two decades has advanced our understanding of the pathophysiology of ischemic stroke. However, current pharmacologic therapies are still limited to rapid reperfusion using thrombolytic agents, and neuroprotective approaches that can reduce the consequences of ischemic and reperfusion injury, are still not available. To bridge this gap, we have evaluated the long-term efficacy and therapeutic time window of a novel peptide-based neuroprotectant TAT-STEP, derived from the brain-enriched and neuron-specific tyrosine phosphatase STEP...

Sepsis induced myocardial dysfunction (SIMD) is a common complication and leads to an increased mortality. SIMD is closely related to inflammation and oxidative stress. Myricetin exhibits strong capacities of anti-inflammation and anti-oxidative stress, but its pharmacological effects for lipopolysaccharide (LPS) induced cardiac injury remains undefined. This study aimed to explore whether myricetin was efficient to alleviate SIMD in mice and neonatal rat cardiomyocytes injury. Mice administrated with myricetin (100 mg/kg, po, bid) or vehicle groups were challenged with LPS (10 mg/kg, ip), and cardiac functions examined by echocardiography after 12 hr LPS exposure...

Pyridoxamine, a structural analog of vitamin B6 that exerts antiglycative effects, has been proposed as supplementary approach in patients with initial diabetic nephropathy. However, the molecular mechanism(s) underlying its protective role has been so far slightly examined. C57Bl/6J mice were fed with a standard diet (SD) or a diet enriched in fat and fructose (HD) for 12 weeks. After 3 weeks, two subgroups of SD and HD mice started pyridoxamine supplementation (150 mg/kg/day) in the drinking water. HD fed mice showed increased body weight and impaired glucose tolerance, whereas pyridoxamine administration significantly improved insulin sensitivity, but not body weight, and reduced diet-induced increase in serum creatinine and urine albumin...

Hypoxia-induced generation of vasoconstrictors reduces cerebral blood flow (CBF) while nitric oxide (NO) synthase (NOS) and microRNAs (miRNA) in endothelial cells (ECs) suppress vasoconstriction. Safflor yellow B (SYB), a natural plant compound, previously attenuated angiotensin II-mediated injury of ECs and maintained endothelial function. This study investigated the putative involvement of NOS and miRNAs in SYB-mediated resistance to hypoxia-induced vasoconstriction. In vivo, chronic hypoxia was induced in rats, and SYB was administered intravenously...

Traumatic brain injury (TBI) results in direct vascular disruption, triggering edema, and reduction in cerebral blood flow. Therefore, understanding the pathophysiology of brain microcirculation following TBI is important for the development of effective therapies. Optical coherence angiography (OCA) is a promising tool for evaluating TBI in rodent models. We develop an approach to OCA that uses the heart-rate frequency to discriminate between static tissue and vasculature. This method operates on intensity data and is therefore not phase sensitive...

Infectious agents such as lipopolysaccharides (LPS) challenge the functional properties of the alveolar-capillary barrier (ACB) in the lung. In this study, we analyse the site-specific effects of LPS on the ACB and reveal the effects on the individual cell types and the ACB as a functional unit. Monocultures of H441 epithelial cells and co-cultures of H441 with endothelial cells cultured on Transwells® were treated with LPS from the apical or basolateral compartment. Barrier properties were analysed by the transepithelial electrical resistance (TEER), by transport assays, and immunostaining and assessment of tight junctional molecules at protein level...

Tile C pelvic ring injuries are challenging to manage even in the most experienced hands. The majority of such injuries can be managed using percutaneous reduction techniques, and the posterior ring can be stabilized using percutaneous transiliac-transsacral screw fixation. However, a subgroup of patients present with inadequate bony corridors, significant sacral zone 2 comminution or significant lateral/vertical displacement of the hemipelvis through a complete sacral fracture. Percutaneous strategies in such circumstances can be dangerous...
