14-3-3蛋白与细胞凋亡

14 3 3蛋白是Moore和Pere于 196 7年发现的 ,当时他们认为 14 3 3蛋白是脑所特有的一种酸性蛋白 ,并依据其在DEAE 纤维素色谱上的组分数以及在淀粉凝胶电泳中的迁移位置而命名为 14 3 3蛋白。但随后的大量研究表明14 3 3蛋白在所有的真核细胞中均有表达 ,是一个调节蛋白家族 ,能与许多功能不同的信号蛋白结合 ,例如蛋白激酶Raf 1、KSR 1、Bcr、Ca2 +/钙调蛋白激酶、PKC、蛋白磷酸酶cdc2 5c、促凋亡蛋白BAD、抗凋亡蛋白A2 0 、跨膜蛋白受体GA等。这就说明 14 3 3蛋白在信号传导、细胞周期调控、细胞凋亡等过程中具有极其重要的…     

Human immunodeficiency virus 1 favors the persistence of infection by activating macrophages through TNF

Macrophages play a major role in HIV-1 persistence. In the present paper, we demonstrate that the absence of apoptosis in HIV-1-infected primary human monocyte-differentiated macrophages (MDM) correlates with an increase in anti-apoptotic (Bcl-2 and Bcl-x(L)) and a decrease in pro-apoptotic (Bax and Bad) proteins. This is associated with macrophage activation as shown by tumor necrosis factor (TNF) production and NF-kappaB activation upon infection. TNF production was shown to be involved in the upregulation of Bcl-2 and Bcl-x(L) because this increase was abolished by an anti-TNF anti-serum or an inhibitor of TNF synthesis. In parallel, inhibition of TNF production induced an increase in the number of apoptotic cells. Furthermore, using an inhibitor of NF-kappaB activation, we demonstrated that TNF-induced upregulation of Bcl-x(L) and Bcl-2 occurs, respectively, through a NF-kappaB-dependent and an NF-kappaB-independent pathway.

Evaluación de la efectividad de la versión en español de un curso de comunicación de malas noticias

IntroductionGood communication by health professionals is associated with better patient outcomes. The Program to Enhance Relational and Communication Skills (PERCS) has been adapted to other cultures. The objective of this study is to describe the effectiveness of the Spanish version of the PERCS program, from the perspective of the participants, at the end of the course and 6 months after the course.MethodsA process of cultural and epidemiological adaptation of the PERCS program to the reality of Peru was carried out. A qualitative and quantitative approach was used to evaluate the educational impact of the program.ResultsThirty-nine professionals participated voluntarily. Participants found it more difficult to communicate ominous diagnoses (48.15%). Anxiety is the most frequent emotion when faced with difficult communications (77.78%). Almost all (92%) stated that the course improved their preparation, and 88.9% that it reduced their anxiety. At 6 months, participants recognised the importance of honesty and empathy, as well as some steps in conducting the patient-centred interview.DiscussionAn intensive training program in difficult communication can be adapted to Spanish, and positively impact the skills, self-confidence, and self-perception of learning in Peruvian professionals, in relation to promoting communication focused on the needs of the patient and family.     

Bad trip due to anticholinergic effect of cannabis

Cannabis in its various forms has been known since time immemorial, the use of which has been rising steadily in India. ‘Bad trips’ have been documented after cannabis use, manifestations ranging from vague anxiety and fear to profoundly disturbing states of terror and psychosis. Cannabis is known to affect various neurotransmitters, but ‘bad trip’ due to its anticholinergic effect has never been described in literature to the best of author's knowledge. Hereby, the author describes a case of a young adult male experiencing profound anticholinergic effects after being exposed for the first time in his life to bhang, a local oral preparation of cannabis.     

Risk factors for bad splits during sagittal split ramus osteotomy: a retrospective study of 964 cases

To identify the potential risk factors for bad splits, we calculated the incidence of bad splits from 484 patients with 964 cases of sagittal split ramus osteotomy (SSRO) and investigated the association between the occurrence of bad splits and risk factors such as gender, patients’ age, class of occlusion, unimaxillary or bimaxillary surgery, presence of the lower third molar, thickness of the ascending ramus, and the distance from the mandibular canal to the buccal cortical bone. The results showed that 40 sides (4.149%) with bad splits occurred in 36 patients (7.438%). The mean (SD) gap width from the canal to the buccal cortex for the bad split group, at 4.02 (1.20) mm, was narrower (p = 0.003; OR = 0.689; 95% CI = 0.538 to 0.882) than the normal split group 4.80 (1.72) mm. On the contrary, no statistical significance (p > 0.05) was detected between the patients with bad splits and those with normal splits for the other factors. In conclusion, SSRO patients with narrower distances from the mandibular canal to the buccal cortex were more prone to bad splits. More attention should be paid to patients with this risk factor during future surgeries.
