BACKGROUND: Mechanical ventilation is a life-saving procedure for patients with acute respiratory failure, although it may cause pulmonary vascular inflammation and leakage, leading to ventilator-induced lung injury (VILI). Ly6C+high monocytes are involved in the pathogenesis of VILI. In this study, we investigated whether pulmonary infiltrated Ly6C+high monocytes produce vascular endothelial growth factor (VEGF) and contribute to VILI. METHODS: A clinically relevant two-hit mouse model of VILI, with intravenous lipopolysaccharide (LPS, 20 ng/mouse) immediately before high tidal volume (HTV, 20 mL/kg) ventilation (LPS+HTV), was established...

Intestinal inflammation induced with dextran sodium sulfate (DSS) is used to study acute or chronic ulcerative colitis in animal models. Decreased gut tissue anti-inflammatory cytokine IL-10 concentration and mRNA abundance are associated with the development of chronic bowel inflammation. Twelve piglets of 3 days old were fitted with an intragastric catheter and randomly allocated into control and DSS groups by administrating either sterile saline or 1.25 g of DSS/kg body weight (BW) in saline per day, respectively, for 10 days...

Non-traumatic wrist pain remains a diagnostic challenge. An accurate diagnosis is crucial in order to choose the appropriate treatment. We report the case of a 23-year-old female with a four-month history of mainly nocturnal wrist pain. There was no history of trauma or prior surgery. Radiographs and CT scans showed a lytic lesion with central nidus and sclerotic margins in the pisiform bone. Bone scan showed increased uptake in the pisiform bone. The diagnosis of osteoid osteoma was confirmed by histopathological analysis after complete surgical resection...

The revised WHO classification of tumors of the CNS 2016 has introduced the concept of the integrated diagnosis. The definition of medulloblastoma entities now requires a combination of the traditional histological information with additional molecular/genetic features. For definition of the histopathological component of the medulloblastoma diagnosis, the tumors should be assigned to one of the four entities classic, desmoplastic/nodular (DNMB), extensive nodular (MBEN), or large cell/anaplastic (LC/A) medulloblastoma...

OBJECTIVES: Placental abnormalities are a common cause of death in stillbirth, ranking second only to unexplained deaths, though there is wide variation in the proportion attributed to placental disease. In clinical practice, interpretation of the significance of placental findings is difficult, since many placental features in stillbirths overlap with those in live births. Our aim was to examine objectively classified placental findings from a series of > 1000 autopsies following intrauterine death in order to evaluate the role of placental histological examination in determining the cause of death...

BACKGROUND: Cysticercosis is a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium. The subcutaneous form of the disease is a relatively rare clinical entity. Despite its rarity, it is imperative for a radiologist to be aware of this subcutaneous form of the disease and its various radiological patterns while evaluating any subcutaneous swelling. In this paper, we aimed to describe a typical case of 'subcutaneous cysticercosis involving the left anterior chest wall' with high resolution ultrasound findings...

Immune deposits are often observed along the tubular basement membrane in patients with lupus nephritis, but the role of anti-dsDNA antibody deposition on tubulo-interstitial inflammation remains to be investigated. We examined the effect of human polyclonal anti-dsDNA antibodies on inflammatory processes in cultured proximal renal tubular epithelial cells (HK-2 cells) and their association with serum levels of IL-6, IL-8 and MCP-1 in patients. Binding of anti-dsDNA antibodies to HK-2 cells was investigated by cellular ELISA, flow cytometry and immunohistochemistry...

We have examined the development of medication-related osteonecrosis of the jaws (MRONJ) in rats with no previous accumulation of zoledronic acid in the mandible. Ten male Wistar rats (weight 350-400g) were anaesthetised with chloral hydrate 450mg/kg intraperitoneally and the first and second mandibular molars on the left side were extracted. The five experimental rats were given six injections of zoledronic acid 0.18mg/kg over the next four weeks (total dose 1.08mg/kg). Two injections were given at once as an intravenous bolus injection (0...

Good sleep quality has a direct effect on the activity of the neuroendocrine-reproductive control axis and oxidative stress. Thus, the aim of the present study was to evaluate whether sleep restriction (SR) during the peripubertal period impaired the postnatal development of the epididymis in Wistar rats. After 21 days SR (18h per day), epididymides were collected on Postnatal Day (PND) 62 for evaluation of oxidative stress markers, inflammatory profile, sperm count and histopathological and stereological analyses; in addition, the motility of spermatozoa from the vas deferens was examined...

Giant hypothalamic hamartomas (GHH) are extremely rare lesions in infants and usually intrinsically epileptogenic. We present the case of a 10-month-old girl child presenting with drug-resistant seizures and a giant hypothalamic lesion that was confirmed as hamartoma on histopathology. Surgical decompression and disconnection from the hypothalamus was performed with the intent of controlling her seizures. Unfortunately, the patient developed right middle cerebral artery and posterior cerebral artery territory infarction, possibly due to vasospasm or thrombosis of the vessels...
