TL;DR: In this article, the first observation of the B-->D over barD(sJ)(2317) and B->D>D-s*gamma decays based on 123.8x10(6) B (B) was reported.
Abstract: We report the first observation of the B-->(D) over barD(sJ)(2317) and B-->(D) over barD(sJ)(2457) decays based on 123.8x10(6) B (B) over bar events collected with the Belle detector at KEKB. We observe the D-sJ(2317) decay to D(s)pi(0) and the D-sJ(2457) decay to the D(s)(*)pi(0) and D(s)gamma final states. We also set 90% C.L. upper limits for the decays D-sJ(2317)-->D-s*gamma, D-sJ(2457)-->D-s*gamma, D-sJ(2457)-->D(s)pi(0), and D-sJ(2457)-->D(s)pi(+)pi(-).

TL;DR: Accumulating evidence suggests that, at least in yeast, ubiquitin itself may constitute an internalization signal, recognized by a hypothetical receptor, as well as a role in the endocytic process possibly involving its C2 domain, in addition to its role in ubiquitinating endocytosed proteins.
Abstract: In addition to its well-known role in recognition by the proteasome, ubiquitin-conjugation is also involved in downregulation of membrane receptors, transporters and channels. In most cases, ubiquitination of these plasma membrane proteins leads to their internalization followed by targeting to the lysosome/vacuole for degradation. A crucial role in ubiquitination of many plasma membrane proteins appears to be played by ubiquitin-protein ligases of the Nedd4/Rsp5p family. All family members carry an N-terminal Ca2+-dependent lipid/protein binding (C2) domain, two to four WW domains and a C-terminal catalytic Hect-domain. Nedd4 is involved in downregulation of the epithelial Na+ channel, by binding of its WW domains to specific PY motifs of the channel. Rsp5p, the unique family member in S. cerevisiae, is involved in ubiquitin-dependent endocytosis of a great number of yeast plasma membrane proteins. These proteins lack apparent PY motifs, but carry acidic sequences, and/or phosphorylated-based sequences that might be important, directly or indirectly, for their recognition by Rsp5p. In contrast to polyubiquitination leading to proteasomal recognition, a number of Rsp5p targets carry few ubiquitins per protein, and moreover with a different ubiquitin linkage. Accumulating evidence suggests that, at least in yeast, ubiquitin itself may constitute an internalization signal, recognized by a hypothetical receptor. Recent data also suggest that Nedd4/Rsp5p might play a role in the endocytic process possibly involving its C2 domain, in addition to its role in ubiquitinating endocytosed proteins.

TL;DR: The three subtypes of the peroxisome proliferator-activated receptors (PPARα, β/δ, and γ) form heterodimers with the 9-cis-retinoic acid receptor (RXR) and bind to a common consensus response element, which consists of a direct repeat of two hexanucleotides spaced by one nucleotide (DR1).

TL;DR: The results of this prospective study show that autoimmune encephalitis occurred in 27% of patients with herpes simplexEncephalitis, and it was associated with development of neuronal antibodies and usually presented within 2 months after treatment of herpes simple X virus reactivation.
Abstract: Herpes simplex encephalitis can trigger autoimmune encephalitis that leads to neurological worsening. We aimed to assess the frequency, symptoms, risk factors, and outcomes of this complication.
We did a prospective observational study and retrospective analysis. In the prospective observational part of this study, we included patients with herpes simplex encephalitis diagnosed by neurologists, paediatricians, or infectious disease specialists in 19 secondary and tertiary Spanish centres (Cohort A). Outpatient follow-up was at 2, 6, and 12 months from onset of herpes simplex encephalitis. We studied another group of patients retrospectively, when they developed autoimmune encephalitis after herpes simplex encephalitis (Cohort B). We compared demographics and clinical features of patients who developed autoimmune encephalitis with those who did not, and in patients who developed autoimmune encephalitis we compared these features by age group (patients ≤4 years compared with patients >4 years). We also used multivariable binary logistic regression models to assess risk factors for autoimmune encephalitis after herpes simplex encephalitis.
Between Jan 1, 2014, and Oct 31, 2017, 54 patients with herpes simplex encephalitis were recruited to Cohort A, and 51 were included in the analysis (median age 50 years [IQR 5-68]). At onset of herpes simplex encephalitis, none of the 51 patients had antibodies to neuronal antigens; during follow-up, 14 (27%) patients developed autoimmune encephalitis and all 14 (100%) had neuronal antibodies (nine [64%] had NMDA receptor [NMDAR] antibodies and five [36%] had other antibodies) at or before onset of symptoms. The other 37 patients did not develop autoimmune encephalitis, although 11 (30%) developed antibodies (n=3 to NMDAR, n=8 to unknown antigens; p<0·001). Antibody detection within 3 weeks of herpes simplex encephalitis was a risk factor for autoimmune encephalitis (odds ratio [OR] 11·5, 95% CI 2·7-48·8; p<0·001). Between Oct 7, 2011, and Oct 31, 2017, there were 48 patients in Cohort B with new-onset or worsening neurological symptoms not caused by herpes simplex virus reactivation (median age 8·8 years [IQR 1·1-44·2]; n=27 male); 44 (92%) patients had antibody-confirmed autoimmune encephalitis (34 had NMDAR antibodies and ten had other antibodies). In both cohorts (n=58 patients with antibody-confirmed autoimmune encephalitis), patients older than 4 years frequently presented with psychosis (18 [58%] of 31; younger children not assessable). Compared with patients older than 4 years, patients aged 4 years or younger (n=27) were more likely to have shorter intervals between onset of herpes simplex encephalitis and onset of autoimmune encephalitis (median 26 days [IQR 24-32] vs 43 days [25-54]; p=0·0073), choreoathetosis (27 [100%] of 27 vs 0 of 31; p<0·001), decreased level of consciousness (26 [96%] of 27 vs seven [23%] of 31; p<0·001), NMDAR antibodies (24 [89%] of 27 vs 19 [61%] of 31; p=0·033), and worse outcome at 1 year (median modified Rankin Scale 4 [IQR 4-4] vs 2 [2-3]; p<0·0010; seizures 12 [63%] of 19 vs three [13%] of 23; p=0·001).
The results of our prospective study show that autoimmune encephalitis occurred in 27% of patients with herpes simplex encephalitis. It was associated with development of neuronal antibodies and usually presented within 2 months after treatment of herpes simplex encephalitis; the symptoms were age-dependent, and the neurological outcome was worse in young children. Prompt diagnosis is important because patients, primarily those older than 4 years, can respond to immunotherapy.

TL;DR: In this paper, the authors analyzed trends in mortality from coronary heart disease (CHD) and cerebrovascular disease (CVD) over the period 1965 to 1998 in the European Union, other European countries, the USA, and Japan.
Abstract: Objective: To analyse trends in mortality from coronary heart disease (CHD) and cerebrovascular disease (CVD) over the period 1965 to 1998 in the European Union, other European countries, the USA, and Japan. Methods and results: Data were derived from the World Health Organization database. In the European Union, CHD mortality in men rose from 146/100 000 in 1965–9 to 163/100 000 in 1975–9 and declined thereafter to 99/100 000 in 1995–8 (−39%). In women, the fall was from 70 to 45/100 000 (−36%). A > 55% decline in CVD was registered in both sexes. In eastern Europe, mortality from both CHD and CVD rose up to the early 1990s but has declined over the past few years in Poland and the Czech Republic. In the Russian Federation during 1995–8, mortality rates from CHD reached 330/100 000 men and 154/100 000 women and mortality rates from CVD were 203/100 000 men and 150/100 000 women—that is, they were among the highest rates worldwide. In the USA and Japan, long term trends were favourable for both CHD and CVD. Conclusions: Trends in mortality from CHD and CVD were favourable in several developed areas of the world, but there were major geographical differences. In a few eastern European countries, mortality from CHD and CVD remains exceedingly high.
