Type II diabetics with macrovascular complications: polymorphonuclear leukocyte (PMN) filtration, PMN membrane fluidity and cytosolic Ca2+ content af…

1998

We evaluated polymorphonuclear (PMN) filtration parameters, membrane fluidity and cytosolic Ca2+ content in 21 normal subjects and in 18 type II diabetics with macrovascular complications (MVC). Evaluations were carried out at baseline and after in vitro activation prolonged for 5 and 15 min. PMA (4-phorbol 12-myristate 13-acetate) and fMLP (N-formyl-methionyl-leucyl-phenylalanine) were used as stimulating agents. TMA-DPH (1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene) was used as fluorescent probe for the membrane fluidity tests and Fura 2-AM for the cytosolic Ca2+ content. A significant variation was evident in PMN filtration parameters at 5 and 15 min. No variation was present i…

Effect of propylene glycol on pre- and post-partum performance by dairy ewes

2005

This study was carried out in order to determine the effects, after feeding propylene glycol to Valle del Belice ewes 30 days prepartum and 30 days postpartum, on metabolic profiles, body-condition score, milk yield, milk composition, milk clotting ability and the performance of suckling lambs. Ewes were blocked by parity, body-condition score and previous milk production, and assigned randomly to either a control diet or a diet containing propylene glycol fed at the rate of 80 g/ewe/day (low PG) or 160 g/ewe/day (high PG). Feeding propylene glycol prepartum decreased the concentration of BHBA and NEFA and increased the concentration of glucose in the ewes’ plasma. Milk yield from ewes fed …

Studies on the mechanism of PMN activation III. by lymphokines.

1983

The influence of a guinea pig lymphokine preparation on the oxidative metabolism of human and guinea pig granulocytes of various sources was investigated. A dose-dependent increase of the oxidative burst following lymphokine challenge was observed. It occurred in unstimulated guinea pig peripheral polymorphonuclear leukocytes (PMN) and in prestimulated PMN obtained from the peritoneal cavity after glycogen injection as well. The lymphokine effect on the oxidative metabolism is not species-restricted because the guinea pig lymphokine preparation elicits an oxidative burst in human PMN, too. The increase caused by lymphokines is nearly of the same order of magnitude as that obtained with zymo…

Feasibility and acceptability of the pelvic floor muscle and bladder training programme

2008

Pelvic floor muscle training (PFMT) is the most commonly used physical therapy treatment for urinary incontinence, and it is more effective when combined with bladder training (BT) than alone. However, to our knowledge, there are no earlier intervention studies of the user feasibility and acceptability of the pelvic floor muscle and BT programme. The aim of this study was to pilot test the feasibility and acceptability and follow the compliance of the 8-week pelvic floor muscle and BT programme. Pre–post intervention study among 11 community-dwelling women born in 1936 with self-reported urinary incontinence and without current PFMT was practised. Primary outcomes were the feasibility, acce…

Community detection-based deep neural network architectures: A fully automated framework based on Likert-scale data

2020

[EN] Deep neural networks (DNNs) have emerged as a state-of-the-art tool in very different research fields due to its adaptive power to the decision space since they do not presuppose any linear relationship between data. Some of the main disadvantages of these trending models are that the choice of the network underlying architecture profoundly influences the performance of the model and that the architecture design requires prior knowledge of the field of study. The use of questionnaires is hugely extended in social/behavioral sciences. The main contribution of this work is to automate the process of a DNN architecture design by using an agglomerative hierarchical algorithm that mimics th…

Ocular Motor Palsy After Spinal Puncture

2017

Abstract Ocular motor palsy is a rare but alarming complication of subarachnoid puncture. In order to better understand this condition, a literature search was performed in English of PubMed articles for cranial nerves III, IV, and VI palsies after spinal puncture. Sixty-five articles (dated 1930–2015) were identified, and 114 cases were obtained for analysis. Subarachnoid anesthesia was the most frequent cause (45.6%), with a higher incidence for females than males. The age of patients was 40.24 ± 13.35 years (age range, 6–71 years). The sixth cranial nerve was the most commonly involved (92.1%), with higher frequency in the right eye. Palsy onset started 7.30 ± 4.09 days after puncture. D…

Safety and Feasibility of Robotic-Assisted Drainage of Symptomatic Pancreatic Pseudocysts: A Case-Series Analysis (with video).

2021

Background: The surgical treatment of pancreatic pseudocysts (PPs) in patients who fail nonoperative management has evolved from aggressive open to a minimally invasive approach. The application of robotic surgery in this setting is scarcely reported. The aim of this study is to analyze the safety and feasibility of the robotic approach to pancreatic pseudocyst drainage. Methods: A single centre retrospective review of consecutive patients undergoing robotic-assisted pancreatic pseudocyst surgeries in an academic tertiary institution was performed. Results: There were 14 patients studied, of whom 10 underwent cystogastrostomy and 4 Roux-En- Y cystojejunostomy. Eight patients had gallstone p…

Aquaporin-4 distribution in control and stressed astrocytes in culture and in the cerebrospinal fluid of patients with traumatic brain injuries

2012

Distribution of aquaporin-4 (AQP4) was studied by western analysis and immunofluorescence in rat astrocytes exposed to either hypothermic (30 °C) or hyperosmolar (0.45 M sucrose) stress, and in the cerebrospinal fluid (CSF) of patients who suffered traumatic brain injury (TBI). CSF was obtained from 5 healthy subjects and from 20 patients suffering from severe TBI. CSF samples were taken at admission and on days 3 and 5-7. Here we report that, in response to both hypothermia and hyperosmolar stress, AQP4 was markedly reduced in cultured astrocytes. We also found that AQP4 significantly increased in patients with severe brain injury in respect to healthy subjects (P < 0.002). AQP4 in CSF rem…

Overexpression of nerve growth factor in peritoneal fluid from women with endometriosis may promote neurite outgrowth in endometriotic lesions

2011

To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis- associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically proven endometriosis and 20 PF from patients with other gynecologic conditions were analyzed with Western blot and a novel in vitro model using dorsal root ganglia (DRG) to show neuronal outgrowth; endometrial cells also were analyzed. The results suggest that the PF of endometriosis patients and endometriotic lesions have neurotropic properties, because the Western blot analysis and the cell culture stainings showed NGF expression, and the neurite outgr…
