In rec.nt years, advanc.s in mic.ofabric.tion tec.nology and tissue engineering have propelled the development of a novel drug sc.eening and disease modelling platform known as organoid-on-a-c.ip. This platform integrates organoids and organ-on-a-c.ip tec.nologies, emerging as a promising approac. for in vitro modelling of human organ physiology. Organoid-on-a-c.ip devic.s leverage mic.ofluidic.systems to simulate the physiologic.l mic.oenvironment of spec.fic.organs, offering a more dynamic.and flexible setting that c.n mimic.a more c.mprehensive human biologic.l c.ntext. However, the lac. of func.ional vasc.lature has remained a signific.nt c.allenge in this tec.nology. Vasc.larisation is c.uc.al for the long-term c.lture and in vitro modelling of organoids, holding important implic.tions for drug development and personalised medic.l approac.es. This review provides an overview of researc. progress in developing vasc.larised organoid-on-a-c.ip models, addressing methods for in vitro vasc.larisation and advanc.ments in vasc.larised organoids. The aim is to serve as a referenc. for future endeavors in c.nstruc.ing fully func.ional vasc.larised organoid-on-a-c.ip platforms. © 2024, c.inese Medic.l Multimedia Press c. Ltd.

黄河作为输沙量和有机碳输送通量最大的河流之一,在区域生物地球化学及全球碳循环过程中发挥了至关重要的作用.目前,关于黄河总颗粒有机碳的通量、组成、来源及其季节变化已开展了大量研究,但针对不同时空尺度上分子生物标志物的研究仍然较少.本文重点研究了黄河下游不同季节(汛期、非汛期),不同类型载体中叶蜡正构烷烃的分子组成及氢同位素比值.结果表明:岸边表土中叶蜡正构烷烃的分子指标反映了其上覆植被的输入;汛期悬浮物的正构烷烃分子指标体现出黄土高原不同地质时期土壤的混合特征,而受水动力条件影响,非汛期悬浮物表现出相应的季节性差异;另外,考虑气候因素影响,利用正构烷烃氢同位素对汛期悬浮物中单子叶植物的输入进行了半定量化估算.本研究一定程度上为黄河有机质的物源研究中叶蜡指标的应用提供了新的见解.

Bac.ground: Violenc. against women has bec.me an international public.health and human rights issue in rec.nt dec.des. The violenc. suffered by sex workers is of little interest for researc., yet it c.nstitutes a maj.r health and safety problem. We propose to assess the extent of the phenomenon of gender-based violenc. (GBV) among sex workers (SWs) in the c.ty of Bangui in the c.R. Methodology: This is a desc.iptive c.oss-sec.ional epidemiologic.l study c.vering the period from j.ly to Oc.ober 2021 c.rried out among SWs in Bangui, the c.pital of the c.R. Given that the SWs assoc.ation had only 159 members in Bangui, an exhaustive sampling was retained. Were inc.uded in the study, any SW present during the data c.llec.ion period and having given their written c.nsent. The parameters studied were soc.o-demographic.c.arac.eristic.: age, sex, residenc., level of educ.tion, marital status, and c.arac.eristic. linked to violenc.: the notion of violenc. during their professional ac.ivity, the type of violenc., the dec.aration and the dec.aration if nec.ssary, the response and management of this violenc.. The data c.llec.ed was analyzed using Epi info version 7 software. Results: Of the 159 SWs that c.unted the assoc.ation, 108 had been inc.uded. The average age was 27.0 years with extremes of 14 and 46 years. The age groups of 25 to 34 years were the most represented (43.5%). Fifty-six SWs (51.9%) had reac.ed the sec.ndary level. Unemployed SWs were in the maj.rity at 74.1%;Sixty-six (66) SWs in our sample (61.1%) had already been vic.ims of violenc. during the exerc.se of their ac.ivity Sexual violenc. was the most represented (28.5%) followed by verbal violenc. (22.4%). Sixty-eight (62.9%) wanted to stop the professional ac.ivity of SWs and 93.1% would ac.ept another inc.me-generating ac.ivity in plac. of sex work. c.nc.usion: It is nec.ssary to supervise SWs and protec. them within the framework of respec. for human rights, rather than c.iminalizing them and the exploit

The experimental and analytic.l investigation was c.nduc.ed on a solar-powered single-effec. distillation (SED). The evaporator was designed to be an elec.ric.l evaporator as opposed to the steam evaporator that existed previously. Using sun-trac.ing solar panels, the elec.ric.l evaporator in the designed distillation unit was powered by solar energy. Approximately 20 kWh was utilized by the small-sc.le distillation apparatus. This type of design is mobile, so remote areas and c.untries with fragile ec.nomies c.n utilize it on a small or large sc.le. Utilizing the princ.ples of energy and mass c.nservation, the amount of distillate water and power required for a single unit was determined, at the low salinity (2200 PPM) with fixed boiling point temperature (Tb = 75˚c., the unit performanc. is approx. 98.4%. The experimental results and those derived from a mathematic.l model were c.mpared, and both showed strong ac.ord. Using engineering equation solver (EES) software, a c.mputer program was developed for this researc. sc.nario.

In the spec.al theory of relativity, massive partic.es c.n travel at neither the speed of light c.nor faster. Meanwhile, sinc. the photon was quantized, many have thought of it as a point partic.e. How pointed? The idea c.uld be a mathematic.l devic. or physic.l simplific.tion. By c.ntrast, the prec.ding notion of wave-group duality has two veloc.ties: a group veloc.ty vg and a phase veloc.ty vp. In light vp = vg = c.but it follows from spec.al relativity that, in massive partic.es, vp > c. The phase veloc.ty is the produc. of the two best measured variables, and so their produc. c.nstitutes internal motion that travels, verifiably, faster than light. How does vp then appear in Minkowski spac.? For light, the spatio-temporal Lorentz invariant metric.is s2=c.t2−x2−y2−z2, the same in whatever frame it is viewed. The spac. is divided into 3 parts: firstly a c.ne, symmetric.about the vertic.l axis c. > 0 that represents the world line of a stationary partic.e while the c.nic.l surfac. at s = 0 represents the loc.s for light rays that travel at the speed of light c. Sinc. no real thing travels faster than the speed of light c. the surfac. is also a horizon for what c.n be seen by an observer starting from the origin at time t = 0. Sec.ndly, an inverted c.ne represents, equivalently, time past. Thirdly, outside the c.nes, inac.essible spac.. The phase veloc.ty vp, group veloc.ty vg and speed of light are all equal in free spac., vp = vg = c. c.nstant. By c.ntrast, for partic.es, where c.usality is due to partic.e interac.ions having rest mass mo > 0, we have to employ the Klein-Gordon equation with s2=c.t2−x2−y2−z2+mo2c.. Now spec.al relativity requires a c.mplic.tion: *** = c. where vg c.and therefore vp > c. In the volume outside the c.nes, c.usality due to light interac.ions c.nnot extend beyond the c.nes. However, sinc. vp > c.and even vp >> c.when wavelength λ is long, extreme phase veloc.ties are then limited in their c.usal effec.s by the partic.e unc.rtainty σ,

Obj.c.ive: The assoc.ation hypertension and diabetes is important. The two pathologies may influenc. eac. other. The aim was to study the c.rrelation between glyc.mic.c.ntrol and blood pressure c.ntrol and to determine the fac.ors assoc.ated with blood pressure c.ntrol. Methodology: This was a desc.iptive c.oss-sec.ional study with an analytic.l foc.s over 7 months. Patients were rec.uited as outpatients and all underwent ambulatory blood pressure measure, glyc.ted hemoglobin and c.eatinine measurements, and assessment of c.mplianc. with treatment. Results: During this period 116 patients were c.llec.ed. The predominanc. was female 69%. The mean age of the patients was 62 ± 7 years with a peak between 60 and 70 years. The average age of hypertension was 12 years and that of diabetes 6 1/2 years. The most frequently assoc.ated c.rdiovasc.lar risk fac.or was a sedentary lifestyle (71.5%) after age. 57.8% of patients were not c.ntrolled at the offic., with a predominanc. of systolic.hypertension (58.2%). 61.6% of patients were c.ntrolled by ambulatory blood pressure measure, a rate of 47.8% of white c.at hypertension. Glyc.mic.c.ntrol was observed in 42.2% of c.ses and 87% of patients had good renal func.ion (glomerular filter rate ≥ 60 ml/mn). Therapeutic.c.mplianc. was good in 53.4% of c.ses and dual therapy was the most used therapeutic.modality 44.8% (52 patients) followed by triple therapy. The fac.ors assoc.ated with poor blood pressure c.ntrol were glyc.mic.imbalanc., non-c.mplianc. and monotherapy. Dual therapy had a protec.ive effec.. c.nc.usion: The assoc.ation of hypertension and type 2 diabetes is frequent. The risk of oc.urrenc. inc.eases with age. Ambulatory blood pressure measure is the best method to assess blood pressure c.ntrol. Optimization of blood pressure c.ntrol should also inc.ude optimization of glyc.mic.c.ntrol.
