Animals depend on other species to live, with monophagy being an extreme mode. Monophagous animals depend on their diet not only for nutritients but also for developmental and reproductive controls. Thus, dietary components may be useful in culturing tissues from monophagous animals. We hypothesized that a dedifferentiated tissue from the monophagous silkworm, Bombyx mori, would re-differentiate when cultured in a medium containing an extract of mulberry (Morus alba) leaves, the only food of B. mori. Over 40 fat-body transcriptomes were sequenced, and we concluded that it is possible to establish in vivo-like silkworm tissue cultures using their diet.

动物依靠其他物种生存,单食是一种极端模式。单食动物不仅依赖食物获取营养,还依赖食物控制发育和繁殖。因此,食物中的成分可能有助于培养单食动物的组织。我们假设,在含有桑叶(桑蚕唯一的食物)提取物的培养基中培养单食性蚕蛾的去分化组织时,该组织将重新分化。我们对 40 多个脂肪体转录组进行了测序,并得出结论:利用蚕的食物建立类似于活体的蚕组织培养是可能的。

Although angiosperms are clearly and strictly defined by their enclosed seeds and enclosed ovules, how old angiosperms are remains controversial. To solve this problem, the only reliable way is digging fossils. The currently widely accepted earliest age for angiosperms is the Early Cretaceous, although this view is facing increasing challenges from pre-Cretaceous fossil evidence of angiosperms as well as molecular clock estimates. Here we report a Palaeozoic angiosperm, Taiyuanostachya gen. nov. This fossil plant has both enclosed ovules and enclosed seeds, features characteristic of angiosperms. Especially, enclosed ovules are idiosyncratic of angiosperms. The occurrences of both characters in Taiyuanostachya declare that angiosperms, the single most diversified plant group on the Earth, have occurred on the Earth in the Palaeozoic, and the origination of angiosperm appears to be much earlier than assumed previously. Although appearing astonishing, this conclusion is in line with the outcomes of molecular clock estimates done decades ago. The discovery of Taiyuanostachya gen. nov is an abominable challenge for botanists who believe groundlessly that angiosperms cannot exist before the Cretaceous.
尽管被子植物被明确而严格地定义为其封闭的种子和封闭的胚珠,但被子植物的年龄仍然存在争议。要解决这个问题,唯一可靠的方法就是挖掘化石。目前被广泛接受的被子植物最早的年龄是早白垩纪,尽管这一观点正面临着来自白垩纪前被子植物化石证据和分子钟估计的越来越多的挑战。本文报道了一株古生代被子植物Taiyuanostachya gen. 11 .,该化石植物具有被子植物的封闭胚珠和封闭种子。特别地,被封闭的胚珠是被子植物的特质。这两个特征的出现,说明被子植物作为地球上最多样化的单一植物类群,早在古生代就已经出现在地球上,被子植物的起源似乎比以前的假设要早得多。尽管看起来令人惊讶,但这一结论与几十年前对分子钟的估计结果一致。对于那些毫无根据地认为被子植物在白垩纪之前不可能存在的植物学家来说,Taiyuanostachya gen. nov的发现是一个可怕的挑战。

Regulatory T cells (Tregs) has been consider as a potential biomarker in rheumatologic clinical trials as this cell population has been shown to be involved in the autoimmune diseases outcome. Human Tregs are defined as CD4 + CD25 +/high CD127 -/low cells; however its accurate identification by flow cytometry has been argued, especially as a result of different gating strategies. A flow cytometry gating strategy was settled to measure human Tregs from PBMC isolated via density gradient using CPT tubes. With this method we performed a standardized procedure for Treg profiling, useful for immunomonitoring in clinicals assessment

. Abstract Background: Urothelial Bladder Cancer (UBC) is one of the most lethal cancers worldwide, the 5-year survival rate remains poor with platinum-based chemotherapy regimens as the standard of cancer treatment protocol. Recent FDA approval of a programmed death ligand-1 (PD-L1) inhibitor, atezolizumab, in advanced UBC patients is changing the therapeutic landscape. Although the response to anti-PD-L1 is correlated to PD-L1 expression and tumor mutation burden, the molecule determinants of responsiveness or non-responsiveness to Immune Checkpoint Inhibitor (ICI) is largely unknown. Methods: R package maftools was used for genomic characterization and differential mutational analysis. EdgeR and DysRegSig algorithm were used for differential gene expression and dysregulator analysis. ConcensusTME algorithm was used for deconvolution of cell types within tumor microenvironment from bulk RNAseq data. Result: A published immunotherapy cohort with whole exome sequencing, RNAseq and clinic outcome data for 29 metastatic urothelial cancer patients was used, paralleled with The Cancer Genome Altas (TCGA) Bladder Cancer cohort,
。背景:尿路上皮性膀胱癌(UBC)是世界范围内最致命的癌症之一,其5年生存率仍然很低,以铂类化疗方案为标准的癌症治疗方案。最近FDA批准了一种程序性死亡配体-1 (PD-L1)抑制剂atezolizumab,用于晚期UBC患者,正在改变治疗前景。尽管对抗PD-L1的反应与PD-L1表达和肿瘤突变负担相关,但对免疫检查点抑制剂(ICI)的反应性或无反应性的分子决定因素在很大程度上是未知的。方法:采用R包maftools进行基因组鉴定和差异突变分析。EdgeR和DysRegSig算法用于差异基因表达和异常分析。使用concensusme算法从大量RNAseq数据中对肿瘤微环境中的细胞类型进行反卷积。结果:采用已发表的免疫治疗队列,包括29例转移性尿路上皮癌患者的全外显子组测序、RNAseq和临床结局数据,并与癌症基因组Altas (TCGA)膀胱癌队列进行对照。

Objective: The objective of this study is to assess the efficacy of BiotiQuest™ Sugar Shift, a probiotic formulated to transform monosaccharides, rehabilitated human gut microbiota, stabilize HbA1c and blood glucose, improve insulin resistance and reduce inflammation Methods: A double-blind, placebo-controlled study was carried out over 12 weeks with 64 Cubans, aged 30 to 65 with Type 2 Diabetes Mellitus diagnosed, 18 of whom being treated with insulin. Participants were randomly assigned to take either two capsules of the probiotic supplement or of placebo. Clinical measures were evaluated at 28-day intervals, included fasting and post-prandial glucose, HbA1c, lipid panel, insulin, creatinine, and serum lipopolysaccharide levels were assessed. Results: The treated group demonstrated a stabilization in their fasting blood glucose and postprandial glucose levels in treated group respect to the Placebo cohort. The HbA1c levels did not show significant changes in the treated group. The insulin levels decreased significantly in the treated group by day 84 compared to day 1 and to day 84 of the Placebo cohort (p=0.024 and p=0.015, respectively). Serum LPS levels also decreased significantly in the treated group (p=0.001). Conclusions: BiotiQuest™ Sugar Shift is suitable as adjunct therapy for the control of T2D. However, the 12-week trial period was not sufficient to detect significant reductions in all clinical parameters measured and a longer study is recommended.
目的:本研究的目的是评估BiotiQuest™Sugar Shift的疗效,BiotiQuest™Sugar Shift是一种益生菌,用于转化单糖,恢复人体肠道微生物群,稳定HbA1c和血糖,改善胰岛素抵抗和减少炎症。方法:对64名古巴人进行了为期12周的双盲,安慰剂对照研究,年龄在30至65岁之间,诊断为2型糖尿病,其中18人接受胰岛素治疗。参与者被随机分配服用两粒益生菌补充剂或安慰剂。每隔28天评估一次临床指标,包括空腹和餐后血糖、糖化血红蛋白(HbA1c)、血脂、胰岛素、肌酐和血清脂多糖水平。结果:与安慰剂组相比,治疗组的空腹血糖和餐后血糖水平稳定。治疗组HbA1c水平无明显变化。与安慰剂组的第1天和第84天相比,治疗组的胰岛素水平在第84天显著下降(p=0.024和p=0.015分别)。治疗组血清LPS水平也显著降低(p=0.001)。结论:BiotiQuest™Sugar Shift适合作为控制T2D的辅助治疗。然而,12周的试验期不足以检测到所有临床参数的显著降低,建议进行更长的研究。

Gating Of the Channel Pore of Ionotropic Glutamate Receptors with Bacterial Substrate Binding Proteins: Functional Coupling of the Ectoine Binding Protein Ehub to Glur0 细菌底物结合蛋白对离子型谷氨酸受体通道孔的门控:外托因结合蛋白Ehub与Glur0的功能偶联

Mammalian neuronal tetrameric ionotropic glutamate receptors (iGluRs) are thought to have originally arisen from the fusion of a bacterial substrate binding protein (SBP) with an inverted potassium channel. This hypothesis is based on structural and sequential similarities between the ligand binding and channel domains of iGluR subunits with SBPs and potassium channels. Ligand binding occurs at the interface between two lobed domains in both ligand binding domains (LBDs) and leads to closure of the shell-like structure, which is considered to be a key element in the transition from ligand recognition to ion channel gating in iGluRs. Here we report the functional coupling of the ectoine-binding protein EhuB to the channel pore of the GluR0 receptor. Fusion of an unmodified EhuB-binding protein to the transmembrane domain of GluR0 did not result in activation of the channel pore. Only by stabilizing the inserted EhuB-binding domain with a dimerization interface the resulting chimera was activated by ectoine, resembling the activation properties of other iGluRs. These results demonstrate the functional compatibility of SBPs to the gate of the channel pore of an iGluR and highlight the role of LBD dimerization in the functional evolution of iGluRs. Based on the high specificity and affinity of SBPs for an incredible variety of substrates, our results demonstrate the competence of SBP/ion channel chimeras for the development of new Biosensors for specific recognition of analytes by functionally linking a bacterial binding protein to the channel pore of an iGluR.
哺乳动物神经元四聚异离子型谷氨酸受体(iGluRs)最初被认为是由细菌底物结合蛋白(SBP)与反向钾通道融合而产生的。这一假设是基于iGluR亚基的配体结合和通道结构域与sbp和钾通道之间的结构和序列相似性。配体结合发生在两个配体结合域(lbd)的两个叶状结构域之间的界面上,并导致壳状结构的关闭,这被认为是iGluRs中从配体识别到离子通道门控过渡的关键因素。在这里,我们报道了外托素结合蛋白EhuB与GluR0受体通道孔的功能偶联。未修饰的ehub结合蛋白与GluR0的跨膜结构域融合不会导致通道孔的激活。只有用二聚化界面稳定插入的ehub结合域,嵌合体才能被异托因激活,类似于其他iGluRs的激活特性。这些结果证明了sbp与iGluR通道孔门的功能相容性,并突出了LBD二聚化在iGluR功能进化中的作用。基于SBP对多种底物的高特异性和亲和力,我们的研究结果证明了SBP/离子通道嵌合体通过将细菌结合蛋白连接到iGluR的通道孔上,可以开发出新的生物传感器,用于特异性识别分析物。

Porphyria is a very rare genetic pathology due to congenital defects of heme metabolism with deficiency of one of the enzymes that determine specific forms of porphyria. Acute hepatic porphyrias (AEP) includes four different clinical forms: a) from ALA D deficiency, b) acute intermittent porphyria, c) hereditary coproporphyria and d) variegate porphyria. The forms of porphyria are characterized by elevated levels of delta aminolevulinic acid (ALA) and porphobilinogen (PBG). Acute intermittent porphyria (AIP) is caused by a genetic mutation of hydroxymethylbilane synthetase (HMBS), which in a good percentage (about 20% of cases) does not show a positivity for hepatic porphyria on biomolecular examination, so that diagnosis with relative therapy is determined by the clinical condition. Our study describes a 54-year-old woman who, due to a porphyria crisis, presented serious symptoms with progressive aggravation that lead her to be hospitalized in an intensive care unit where she was intubated due to tetraplegia and severe respiratory failure. Treatment with human emin first and Givosiran subsequently allowed progressive amelioration of the clinical conditions.
卟啉症是一种非常罕见的遗传病理,由于先天性缺陷的血红素代谢缺乏一种酶,决定特定形式的卟啉症。急性肝性卟啉症(AEP)包括四种不同的临床形式:a) ALA D缺乏症,b)急性间歇性卟啉症,c)遗传性比例卟啉症和D)多样性卟啉症。卟啉症的特点是δ氨基乙酰丙酸(ALA)和卟啉胆色素原(PBG)水平升高。急性间断性卟啉症(AIP)是由羟甲基双烷合成酶(HMBS)基因突变引起的,有相当一部分(约20%)的病例在生物分子检查上未表现为肝性卟啉症阳性,因此需要根据临床情况确定是否需要相应的治疗。我们的研究描述了一名54岁的女性,由于卟啉症危象,出现了严重的症状并逐渐加重,导致她因四肢瘫痪和严重呼吸衰竭而住进了重症监护病房,在那里她接受了插管治疗。首先用人emin治疗,随后用吉沃西兰治疗,可使临床状况逐步改善。

This paper presents information about Crambe Abyssinica Hochst and discusses various aspects of oil planting, extraction and treatment, chemical composition, and the physical and chemical properties of the oil. In addition, it discusses the possibility of its use as a raw material for biofuels. Crambe Abyssinica Hochst is an oilseed from the Mediterranean that has good oil content in its seed (~ 38%). Other advantages are presented as the short growth period and can be grown in environments considered unsuitable, which are desirable requirements for use in the production of biofuels. Crambe oil has erucic acid as its main fatty acid, which is not edible, so it is an oil that does not compete with the food industry. This crop is already used in the industry in various parts of the world for the production of various products, including biodiesel with oxidative stability considered promising.
本文介绍了有关克兰贝的资料,并讨论了油的种植、提取和处理、化学成分以及油的物理和化学性质的各个方面。此外,它还讨论了将其用作生物燃料原料的可能性。海芋(Crambe Abyssinica Hochst)是一种产自地中海的油籽,种子含油量高(~ 38%)。其他优点是生长期短,可以在被认为不合适的环境中生长,这是用于生产生物燃料的理想要求。鹰嘴豆油以芥酸为主要脂肪酸,不能食用,所以是一种不与食品工业竞争的油。这种作物已经在世界各地的工业中用于生产各种产品,包括被认为具有氧化稳定性的生物柴油。
