Pheromones linked to sexual behaviors excite the appetitive phase of feeding behavior of Aplysia fasciata II. Excitation of C-PR, a neuron involved i…
1998
Pheromones presumably released by conspecifics amplify both the appetitive and the consummatory components of feeding in Aplysia. These effects can be mimicked by administering homogenate of the large hermaphroditic duct containing atrial gland tissue, as well as peptides from the bag cells. Identified cerebro-pedal regulator (C-PR) neuron is thought to command various behaviors that comprise the appetitive phase of feeding. In a reduced preparation, we investigated the effects on the C-PR of applying these substances to the rhinophores, the sensory organs which detect pheromones. Stimuli that excite feeding in the animal were also found to affect the C-PR. Large hermaphroditic duct homogen…
Apoptotic role of Fas/Fas ligand system in the regulation of erythropoiesis
1999
Abstract The possible involvement of Fas and Fas ligand (FasL) in the regulation of erythropoiesis was evaluated. Immunohistochemistry of normal bone marrow specimens revealed that several immature erythroblasts undergo apoptosis in vivo. Analysis of bone marrow erythroblasts and purified progenitors undergoing unilineage erythroid differentiation showed that Fas is rapidly upregulated in early erythroblasts and expressed at high levels through terminal maturation. However, Fas crosslinking was effective only in less mature erythroblasts, particularly at basophilic level, where it induced apoptosis antagonized by high levels of erythropoietin (Epo). In contrast, FasL was selectively induced…
An international assessment of the adoption of enhanced recovery after surgery (ERAS®) principles across colorectal units in 2019–2020
2021
Aim The Enhanced Recovery After Surgery (ERAS® ) Society guidelines aim to standardise perioperative care in colorectal surgery via 25 principles. We aimed to assess the variation in uptake of these principles across an international network of colorectal units. Method An online survey was circulated amongst European Society of Coloproctology members in 2019/20. For each ERAS® principle, respondents were asked to score how frequently the principle was implemented in their hospital, from 1 ('rarely') to 4 ('always'). Respondents were also asked to recall whether practice had changed since 2017. Subgroup analyses based on hospital characteristics were conducted. Results Of hospitals approache…
The Human Blastocyst Regulates Endometrial Epithelial Apoptosis in Embryonic Adhesion1
2000
The implanting blastocyst must appose and adhere to the endometrial epithelium and, subsequently, invade it. Locally regulated uterine epithelial apoptosis induced by the embryo is a crucial step of the epithelial invasion in rodents. To address the physiological relevance of this process in humans, we investigated the effect of single human blastocysts on the regulation of apoptosis in cultured human endometrial epithelial cells (hEEC) in both apposition and adhesion phases of implantation. Here, we report a co-ordinated embryonic regulation of hEEC apoptosis. In the apposition phase, the presence of a blastocyst rescues hEEC from the apoptotic pathway. However, when the human blastocyst a…
G.P.232
2014
Spinal muscular atrophy (SMA) and Pompe disease (PD) are common neuromuscular disorders during childhood causing progressive weakness of proximal muscles with gait disturbances, loss of ambulation and breathing difficulties. Whereas SMA is the result of a neurogenic atrophy caused by mutations in the SMN1 gene, PD is a lysosomal glycogen storage disease (type II) due to mutations of the GAA gene responsible for the enzyme activity of acid alpha-1,4-glucosidase. PD is treatable by enzyme replacement therapy, but in SMA there is no established curable therapy. We report on a child with genetically proven SMA type III and PD caused by mutations in the SMN1 and GAA genes. A 3 years old girl pre…
Salivary glucose as a non-invasive biomarker of type 2 diabetes mellitus
2018
Background Every year, millions of people are diagnosed with Diabetes mellitus (DM) and the number of new and undiagnosed cases continue to rise. Diagnosis of diabetes is usually performed by blood glucose analysis after fasting for a certain period. However, this method uses an invasive technique that can cause discomfort and even trauma to some patients which could eventually lead to behavioral changes such as avoidance of healthcare and laboratory testing. Studies that explore the diagnostic value of salivary glucose are promising due to the non-invasiveness of the test procedures and its potential correlation with blood results. Material and Methods The study conducted aimed to determin…
Fast-Track Surgery and Early Rehabilitation for Total Hip Replacement in Hospital of Traumatology and Orthopaedics
2019
Abstract Due to an ageing population, the necessity for hip replacement has grown, and therefore, new options are being sought, such as the Fast-track principle, to improve patient condition, reduce their hospital stay and enhance the hospital’s ability to treat more patients. The aim of this study was to investigate the effects of same-day patient mobilisation on pain, side effects, complications, duration of hospital stay, and recovery after primary hip replacement, using intermediate-acting local anaesthetics in spinal anaesthesia (SA). A prospective, randomised study was conducted at the Hospital of Traumatology and Orthopaedics. Forty-six patients undergoing total hip replacement were …
Is 5-ASA Still the Treatment of Choice for Ulcerative Colitis?
2010
5-Amino-salacylic acid (5-ASA) is up to now the treatment of choice in the induction and maintenance of remission of mild-to-moderate ulcerative colitis (UC). Sulfasalazine, despite similar efficacy, is hampered by more side effects, but in presence of peripheral arthopaties it remains the treatment of choice. The new delayed release MMX formulation seems to be promising in reducing compliance problems, but further studies are warranted to show the superiority of new MMX formulation compared with the older formulations of 5-ASA. Some trials evaluated also the efficacy and safety of once-daily dosing of older 5-ASA formulations in maintenance of remission, finding a greater adherence to ther…
Myofascial pain syndrome associated with trigger points: A literature review. (I): Epidemiology, clinical treatment and etiopathogeny
2009
Over the last few decades, advances have been made in the understanding of myofascial pain syndrome epidemiology, clinical characteristics and aetiopathogenesis, but many unknowns remain. An integrated hypothesis has provided a greater understanding of the physiopathology of trigger points, which may allow the development of new diagnostic, and above all, therapeutic methods, as well as the establishment of prevention policies and protocols by the health profession. Nevertheless, randomized studies are needed to provide a better understanding and detection of the different factors involved in the origin of trigger points.
Retarded thymic involution and massive germinal center formation in NF-ATp-deficient mice.
1998
NF-ATp and NF-ATc are the most prominent nuclear NF-AT transcription factors in peripheral T lymphocytes. After T cell activation both factors bind to and control the promoters and enhancers of numerous lymphokine and receptor ligand genes. In order to define a specific role for NF-ATp in vivo we have inactivated the NF-ATp gene by gene targeting in mice. We show that NF-ATp deficiency leads to the accumulation of peripheral T cells with a “preactivated” phenotype, enhanced immune responses of T cells after secondary stimulation in vitro and severe defects in the proper termination of antigen responses, as shown by a reduced deletion of superantigen-reactive CD4+ T cells. These alterations …
