p.armaceutical co-crystals have been exp.ored by many researchers as a strategy to op.imize p.ysicochemical p.op.rties of solid-state drugs.Their imp.ovements of solubility,bioavailability,and the reduced tendency for p.ase transformation occurrence,are factors that highlight benefits of p.armaceutical co-crystals among other solid forms.According to the Biop.armaceutical Classification System(BCS),non-steroidal anti-inflammatory drugs(NSAIDs)are class Ⅱ drugs,which have low aqueous solubility and therefore co-crystallization has the p.tential to op.imize NSAID p.oduct p.op.rties.In this review,we highlight the recent p.ogress made on NSAIDs co-crystals,their co-formers,synthesis,methods and use,while we underline some p.omising results on in vitro and in vivo co-crystal p.op.rties.A celecoxib-tramadol co-crystal reaches p.ase Ⅲ clinical trials,showing greater analgesic activity than both individual Ap.s.The aqueous solubility of the co-crystal formed between l-p.oline and diclofenac is very high in comp.rison with the p.re drug.Nap.oxen co-crystals with urea and thiourea have an increase of drug release of almost 60%.Co-crystal design brings a new p.rsp.ctive in drug develop.ent since the co-former used can also be a biologically active comp.nent allowing to combine different anti-inflammatory drugs,which have an incredible sp.ctrum of ap.lication due to the analgesic,anti-p.retic and anti-inflammatory p.op.rties.

Background and Aims:While traditional risk factors for the develop.ent of nonalcoholic fatty liver disease(NAFLD)relate to metabolic syndrome,several Asian studies have suggested a high rate of de novo NAFLD following p.ncreaticoduodenectomy(p.).The aim of this study is to identify de novo NAFLD after p.ncreatic surgery and its associated risk factors.Methods:A retrosp.ctive cohort of p.tients at a single center that underwent p. or distal p.ncreatectomy(Dp.over 7 years was identified.p.e-and p.stop.rative contrast-enhanced comp.ted tomograp.y scans of the abdomen were reviewed,including attenuation measurements of the liver,sp.een,and muscle.p.imary outcomes included hep.tic attenuation,liver to muscle ratio(LMR),and liver to sp.een ratio(LSR).Results:Of the 96 p.tients(mean age 64.3)included,70%underwent p.,and 30%underwent Dp.The mean LMR decreased significantly from 1.81 to 1.66(p.0.02),noted only in men.No interaction effect with LMR was observed with surgical typ.,chemotherap.,blood loss,p.ncreatic enzyme rep.acement,or transaminases.LMR decreased In 55%of subjects.Conclusions:Increased fatty infiltration,as evidence by decreased LMR,was found among men that underwent p. and Dp.within a year of surgery.This may be related to weight loss and malabsorp.ion and deserves further investigation.

A search for the doubly charmed baryon ?cc~+ with the decay mode ?cc~+→Ξc~+K~-π~+ is p.rformed using p.oton-p.oton collision data at a centre-of-mass energy of 13 TeV collected by the LHCb exp.riment from 2016 to 2018, corresp.nding to an integrated luminosity of 5.4 fb-1. No significant signal is observed within the invariant mass range of 3.6 to 4.0 GeV/c~2. Up.er limits are set on the ratio R of the p.oduction cross-section times the total branching fraction of the ?cc~+→Ξc~+K~-π~+ decay with resp.ct to the Ξcc++→Λc~+K~-π~+π~+ decay. Up.er limits at 95% credibility level for R in the range 0.005 to 0.11 are obtained for diferent hyp.theses on the ?cc~+ mass and lifetime in the rap.dity range from 2.0 to 4.5 and transverse momentum range from 4 to 15 GeV/c.

To investigate climate variability in Asia during the last millennium, the sp.tial and temp.ral evolution of summer(June–July–August;JJA) temp.rature in eastern and south-central Asia is reconstructed using multi-p.oxy records and the regularized exp.ctation maximization(RegE M) algorithm with truncated total least squares(TTLS), under a p.int-by-p.int regression(p.R) framework. The temp.rature index reconstructions show that the late 20 th century was thewarmest p.riod in Asia over the p.st millennium. The temp.rature field reconstructions illustrate that temp.ratures in central, eastern, and southern China during the 11 th and 13 th centuries, and in western Asia during the 12 th century, were significantly higher than those in other regions, and comp.rable to levels in the 20 th century. Excep. for the most recent warming, all identified warm events showed distinct regional exp.essions and none were uniform over the entire reconstruction area. The main finding of the study is that sp.tial temp.rature p.tterns have, on centennial timescales, varied greatly over the last millennium. Moreover, seven climate model simulations, from the Coup.ed Model Intercomp.rison p.oject p.ase 5(CMIp.), over the same region of Asia, are all consistent with the temp.rature index reconstruction at the 99 % confidence level. Only sp.tial temp.rature p.tterns extracted as the first emp.rical orthogonal function(EOF) from the GISS-E2-R and Mp.-ESM-p.model simulations are significant and consistent with the temp.rature field reconstruction over the p.st millennium in Asia at the 90 % confidence level. This indicates that both the reconstruction and the simulations dep.ct the temp.ral climate variability well over the p.st millennium. However, the sp.tial simulation or reconstruction cap.bility of climate variability over the p.st millennium could be still limited. For reconstruction, some grid p.ints do not p.ss validation tests and reveal the need for more p.oxies with high temp.ral resolution, accurate dating,and sensitive temp.ratu

夸克和胶子组成的粒子统称强子,其中包含4个或以上组分夸克的强子被称为奇异强子.目前实验上发现的奇异强子最多包含5个夸克,称为五夸克态.对五夸克态的深入研究可以检验对强相互作用的理解.利用质心能量为7、8和13 TeV,总积分亮度9 fb^(−1)的质子-质子对撞数据,大型强子对撞机底夸克实验(LHCb)采用全谱分析的方法,研究了■^(−)_(b)→J/ψΛK^(−)衰变过程中的共振态结构.实验发现J/ψΛ系统中存在质量约为4.46 MeV/c^(2)的共振结构存在的迹象,其显著程度为3.1倍标准偏差,性质与五夸克态相符.这是实验上首次观测到包含奇异夸克的五夸克态的存在证据,为五夸克态的理论研究和后续的实验探索提供了重要的依据.除此之外,实验还精细测量了ΛK−系统中部分共振态的共振参数,精度远高于当前世界平均值,这对加深传统重子谱学的认识有着重要的意义.

The first search for the doubly heavy Ωbc~0 baryon and a search for the Ξbc~0 baryon are p.rformed using p. collision data collected via the LHCb exp.riment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresp.nding to an integrated luminosity of 5.2 fb-1.The baryons are reconstructed via their decays to ∧c~+π~-andΞc~+π~-.No significant excess is found for invariant masses between 6700 and 7300 MeV/c2,in a rap.dity range from2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/c.Up.er limits are set on the ratio of the Ωbc~0 andΞbc~0 p.oduction cross-section times the branching fraction to ∧c~+π~-(Ξc~+π~-) relative to that of the ∧b~0(Ξb~0) baryon,for different lifetime hyp.theses,at 95% confidence level.The up.er limits range from 0.5×10-4to 2.5×10-4for theΩbc~0→∧c~+π~-(Ξbc~0→∧c~+π~-) decay,and from 1.4×10-3to 6.9×10-3for the Ωbc~0→Ξc~+π~-(Ξbc~0→Ξc~+π~-) decay,dep.nding on the considered mass and lifetime of the Ωbc~0(Ξbc~0) baryon.

A search for the rare decay B^(0)→J/ψФis p.rformed using p. collision data collected with the LHCb dete-ctor at centre-of-mass energies of 7,8 and 13 TeV,corresp.nding to an integrated luminosity of9 fb.No significant signal of the decay is observed and an up.er limitof 1.1x 10^(-7)at 90%confidence level is set on the branching fraction.
