An improved in vivo method for atrioventricular node ablation via thoracotomy BJMBR
MacIver,R.H.; Stewart,R.D.; Backer,C.L.; Tsao,S.; Harrington,D.A.; Mavroudis,C..
The atrioventricular (AV) node is permanently damaged in approximately 3% of congenital heart surgery operations, requiring implantation of a permanent pacemaker. Improvements in pacemaker design and in alternative treatment modalities require an effective in vivo model of complete heart block (CHB) before testing can be performed in humans. Such a model should enable accurate, reliable, and detectable induction of the surgical pathology. Through our laboratory’s efforts in developing a tissue engineering therapy for CHB, we describe here an improved in vivo model for inducing chronic AV block. The method employs a right thoracotomy in the adult rabbit, from which the right atrial appendage may be retracted to expose an access channel for the AV node. A...

Comparative efficacy and safety of contact force-sensing catheter and second-generation cryoballoon ablation for atrial fibrillation: a meta-analysis BJMBR
Zhou,X.; Lv,W.; Zhang,W.; Ye,Y.; Li,Y.; Zhou,Q.; Zhang,J.; Xing,Q.; Lu,Y.; Zhang,L.; Wang,H.; Qin,W.; Tang,B..
This meta-analysis compared the efficacy and safety of the contact force (CF)-sensing catheter and second-generation cryoballoon (CB) ablation for treating atrial fibrillation (AF). Six controlled clinical trials comparing ablation for AF using a CF-sensing catheter or second-generation CB were identified from PubMed, EMBASE, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure. The procedure duration was significantly lower in the CB group compared with that in the CF group [mean difference (MD)=29.4; 95%CI=17.84–40.96; P=0.01], whereas there was no difference between the groups for fluoroscopy duration (MD=0.59; 95%CI=–4.48–5.66; P=0.82). Moreover, there was no difference in the incidence of non-lethal complications (embolic event,...

Effet de l'ablation des pédoncules oculaires en longue et courte photophase sur le développement des gonades chez Palaemon serratus Pennant ArchiMer
Ryckaert, Mireille; Vial, Nelly; Ceccaldi, Hubert J..
Dans ses travaux fondamentaux, Panouse avait montré que l'ablation des pédoncules oculaires provoquait chez les individus femelles de Leander (Palaemon) serratus, un grossissement accéléré de l'ovaire et une ponte plus précoces.

Efficacy of removal of cariogenic bacteria and carious dentin by ablation using different modes of Er:YAG lasers BJMBR
Baraba,A.; Kqiku,L.; Gabrić,D.; Verzak,Ž.; Hanscho,K.; Miletić,I..
The primary objective of this in vitro study was to evaluate the efficiency of removal of cariogenic bacteria and carious dentin by ablation using two lasers: fluorescence-feedback controlled (FFC) Er:YAG laser and different pulses of Er:YAG laser based on variable square pulse technology (VSPt). The secondary objective was to measure the temperature during laser ablation of carious tissue. Seventy-two extracted human molars were used in this study. Sixty teeth with carious dentin were randomly divided into four experimental groups according to the treatment for caries removal: group 1: 400 µs (FFC group); group 2: super short pulse (SSP group, 50 µs pulse); group 3: medium short pulse (MSP group, 100 µs pulse); group 4: short pulse (SP group, 300 µs...

Immediate radical fang mark ablation may allow treatment of japanese viper bite without antivenom J. Venom. Anim. Toxins incl. Trop. Dis.
Fujioka,M; Oka,K; Kitamura,R; Yakabe,A; Ito,M.
Administration of antivenom is currently the standard treatment for snake envenomation. However, it can sometimes cause anaphylactic reactions including urticaria, bronchospasm and hypotension. Furthermore, it may also provoke life-threatening complications, even though the mortality rate is less than 1%. In this study, we present a new treatment - immediate radical fang mark ablation - that was successfully performed on five victims of Japanese viper bites without antivenom use. In these five victims of venomous snakebites, surgical debridement was immediately performed. Two patients received a free-skin graft to resurface their wounds while three of them healed conservatively (i.e. by ointment treatment without surgery). After treatment, all patients...
