Aging of the liver: Age-associated mitochondrial damage in intact hepatocytes

1996

Mitochondrial damage may be a major cause of cellular aging. So far, this hypothesis had only been tested using isolated mitochondria. The aim of this study was to investigate the involvement of mitochondria in aging using whole liver cells and not isolated mitochondria only. Using flow cytometry, we found that age is associated with a decrease in mitochondrial membrane potential (30%), an increase in mitochondrial size, and an increase in mitochondrial peroxide generation (23%). Intracellular peroxide levels were also increased. The number of mitochondria per cell and inner mitochondrial membrane mass did not change. Gluconeogenesis from glycerol or fructose (mitochondrial-independent) did…

HPV Vaccination: The Position Paper of the Italian Society of Colposcopy and Cervico-Vaginal Pathology (SICPCV)

2020

Human papillomavirus (HPV) related cervical cancer represents an issue of public health priority. The World Health Organization recommended the introduction of HPV vaccination in all national public programs. In Europe, vaccines against HPV have been available since 2006. In Italy, vaccination is recommended and has been freely offered to all young girls aged 11 years since 2008. Three prophylactic HPV vaccines are available against high- and low-risk genotypes. The quadrivalent vaccine contains protein antigens for HPV 6, 11, 16, and 18. The bivalent vaccine includes antigens for HPV 16 and 18. The nonavalent vaccine was introduced in 2014, and it targets HPV types 6, 11, 16, 18, 31, 33, 4…

Laparoscopic sacrocolpopexy in the treatment of vaginal vault prolapse: 8 years experience

2009

Abstract Objective The aim of this study was to evaluate the long-term results of a laparoscopic sacrocolpopexy for the treatment of vaginal vault prolapse. Study design Between January 1999 and January 2007, 165 laparoscopic sacrocolpopexy procedures, using a polypropylene mesh, were performed on women affected by vaginal vault prolapse. Intraoperative complications included: 5 bladder injuries and 3 sigmoid perforations. Postoperative complications included: 10 cases of fever, 5 cases of lumbosciatica, 15 cases of detrusor overactivity, 2 cases of vaginal haematoma, and 5 cases of minimal dispareunia. At 1, 6 and 12 months after surgery, a clinical evaluation was carried out for all patie…

Intrinsic activation of GABAA receptors suppresses epileptiform activity in the cerebral cortex of immature mice

2010

SUMMARY Purpose: Activation of ionotropic c-aminobutyric acid type A (GABAA) receptors induces in immature neocortical neurons a membrane depolarization that may contribute to the higher epilepsy susceptibility in newborns. To elucidate whether depolarizing GABAergic responses enhance or attenuate epileptiform activity in the immature neocortex, we investigated the effect of agonists, antagonists, and positive modulators of GABAA receptors on epileptiform activity. Methods: We performed in vitro field potential recordings on isolated whole neocortex preparations and whole cell recordings of identified pyramidal neurons in 400-lm slices of immature (postnatal day 1–7) mice. Epileptiform acti…

Behavioural responsiveness to picrotoxin and desipramine in adult rats prenatally exposed to different benzodiazepine receptor agonists

1995

The behavioural responsiveness to picrotoxin and desipramine was investigated in adult rats prenatally exposed to different benzodiazepine receptor agonists such as diazepam, alprazolam and zolpidem. Prenatal exposure to diazepam and alprazolam similarly potentiated the anti-immobility effect on the forced swimming test and the inhibitory effect on spontaneous motor activity of picrotoxin and desipramine and increased the seizure sensitivity to picrotoxin. Prenatal zolpidem seems to be ineffective. These data suggest that, despite the differences in their pharmacodynamic profile, prenatal exposure to diazepam and alprazolam, but not zolpidem, may have similar permanent consequences on the b…

Is a Vaginectomy Enough or is a Pelvic Exenteration Always Required for Surgical Treatment of Recurrent Cervical Cancer? A Propensity-Matched Study.

2021

Purpose: Reporting the perioperative and survival outcomes of vaginectomy with respect to a matched series of pelvic exenteration (PE) in women with isolated recurrent cervical cancer. Methods: The records of vaginal recurrent cervical cancer patients admitted at Fondazione Policlinico “Agostino Gemelli” IRCCS in Rome from January 2010 to June 2019 were retrospectively analyzed. A propensity-matched score analysis was performed by age, clinical stage, disease-free interval, and R0 resection. Postsurgical complications and survival rates were evaluated. Results: Fifteen women underwent vaginectomy, and 30 patients were submitted to PE. No statistical differences were observed between the two…

L’autoesposizione a pericolo fra colpa in ambiti illeciti e autoresponsabilità: il caso delle morti da assunzione di stupefacenti

2020

La rilevanza dell'autoresponsabilità della vittima viene considerato in relazione al caso della morte del consumatore di droghe. Si tratta di un una problematica ampiamente esaminata nella giurisprudenza tedesca e in quella italiana, con differenti esiti sulle norme applicabili nei due sitemi penali e ulteriori conseguenze dogmatiche sulla teoria generale della responsabilità penale colposa. The relevance of the victim's self-responsibility is considered in relation to the case of the death of the drug user. This issue has been extensively examined in German and Italian jurisprudence, with different outcomes on the applicable rules in the two criminal systems and further dogmatic consequenc…

Patterns of trunk spine growth in two congeneric species of acanthocephalan: investment in attachment may differ between sexes and species.

2012

SUMMARYAcanthocephalans have evolved a hooked proboscis and some taxa have trunk spines to attach to their definitive hosts. These structures are generated before being used, thus a key question is how investment in attachment could optimally be allocated through the ontogeny. The number and arrangement of hooks and spines are never modified in the definitive host, but it is unclear whether these structures grow during adult development. A comparison of the size of trunk spines between cystacanths and adults of Corynosoma cetaceum and C. australe indicated that spines grow in both species, but only in females, which also had significantly larger spines than males. This sexual dimorphism did…
