agreed to. Hence, he was admitted to the Villa Garda Hospital Department of Eating and Weight Disorders on 2 December 2016. At admission, he had a body weight of 101.4 kg (BMI 32.0 kg/m 2 ). According to the Italian version of the 17th edition of the Eating Disorder Examination (EDE) interview [7], he had a global score of 0.74, which is <1 standard de- viation (SD) above the community mean (i.e., under 1.74); he reported no binge-eating episodes or purging behaviours (i.e., self-induced vomiting and laxative or diuretic misuse) over the preceding three months, which indicated the absence of a binge-eating disorder or other types of eating disorder [7]. Fasting blood samples were obtained on the day of admission (Day 1), and laboratory tests (Table 1) showed raised C-reactive protein (1.46 mg/dl; normal values: <0.1 mg/dl), fibrinogen (433 mg/dl; normal values: 150– 400 mg/dl), erythrocyte sedimentation rate (29 mm/h; normal values: 0–20 mm/h), low-density lipoprotein (LDL) cholesterol (121 mg/dl; normal values: <100 mg/dl), insulin (27.8 mcU/ml; normal values: 1.9–23.0 mcU/ml), and HOMA-IR index (5.97; normal values: 0.23–2.5), in addition to reduced high-density lipoprotein (HDL) cholesterol (47 mg/dl; normal values: >60 mg/dl). The clinical pre- sentation was indicative of chronic inflammation in obesity complicated by metabolic syndrome [8].

ment of the potency of the non-selective AR agonist NECA. Automated Docking—We docked ZM241385, NECA, and CGS21680 into the crystal structure at a standard protonation state (as calculated by the H ⫹⫹ server as well as in the FlexX program suite, pH 7.0), and two additional protonation states (pH 5.5 and pH 8.0) (Fig. 4). We used FlexX, which models side chains as rigid moieties, in default mode. We included residues within a 9.0-Å sphere around the ZM241385 binding site without any other constraints (e.g. for a polar interaction from Glu-169(5.30), Asn-253(6.55), or aromatic interaction from Phe-168(5.29), and all crystallographic waters were removed. Without any constraints, ⬎ 95% of the docking results (top 10 solutions obtained per ligand per pH) showed a polar interaction between Asn-253(6.55) and the exo-cyclic amino group of the ligand as well as aromatic stacking interactions between Phe-168(5.29) and either the triazolotriazine core (ZM241385) or adenine ring system (NECA, CGS21680) (Fig. 4). Re-docking of ZM241385 showed the largest variation in the position of the 4-hydroxyphenyl group side chain (Fig. 4A). Interestingly, in 5% of the docking results for NECA and in 20% for CGS21680, the ligand was rotated 180 degrees so that the polar interactions with the receptor via Asn-253(6.55)/Glu- 169(5.30) and aromatic stacking interactions with receptor via Phe-168(5.29) were approximately correct, but the ribose motif was directed toward the extracellular space. In the remaining docking results for both NECA and CGS21680, the ribose motif interactions were similarly oriented and clustered into two ori- entations irrespective of the studied protonation states (Fig. 4). In the first conformation, the ribose motif makes a polar inter- action with backbone of Ala-81(3.29), and in the second con- formation it is in close proximity to Ser-277(7.42) and His-278(7.43). Energy minimization of receptor side chains revealed that in this conformation the ribose group makes polar interactions with Ser-277(7.42) and Thr-88(3.36) (Fig. 4D). The latter conformation of the ribose ring is likely to be more rele-

Estimating  kinetic  parameters  for  essential  amino  acid  production  in arabidopsis thaliana by using particle swarm optimization

Estimating kinetic parameters for essential amino acid production in arabidopsis thaliana by using particle swarm optimization

In conclusion, the performance of PSO in estimating parameter values is better than SA and downhill simplex method after the implementation of PSO into SBToolbox in MATLAB. The simulated results generated by PSO are more consistent, as the standard deviation value is closer to 0 compared to SA and downhill simplex method. The graph also shows that the simulated line of PSO is closer to experimental line. Moreover, the computational time to estimate parameter values for SA and downhill simplex method are longer compared to PSO. This is due to PSO which applies inertia weight to obtain a balance between the local and global exploration and exploitation to avoid getting stuck into the local minima. In addition, PSO takes a shorter time to converge to best solution. Besides that, the acceleration constant that is taken into account in the equation ensures that each particle is pulled towards the pbest and gbest positions. In this research, value 2 was applied. In conclusion, Parameter Estimation through experiment is time consuming, hard and expensive. However, the implementation of PSO into SBToolbox manages to reduce the computational time for parameter estimation. It also reduces the complexity and the cost needed to use to estimate the kinetic parameters since the estimation only involves the use of computer. For future work, the number of run may be increased to ensure the accuracy of the method and more different weight parameters can be implemented to enhance the performance of PSO.

The neurochemistry of amino acid transmitters

The outstanding feature of the GABA uptake system is its specificity. Considerable further kinetic studies of the inhibition patterns of substrate analogues are necessary to investigate the nature of the interactions essential to the formation of the substrate-carrier complex for transport, and the number of binding sites involved, in the hope that the factors responsible for the specificity of the transport system may be completely elucidated. Furthermore so little is known about the carrier involved, it chemical nature and active conformation, or the binding of the substrate and whether a particular conformation is necessary for initial recognition by the carrier and another lipophilic

An analytical study on complexation equilibria of non essential amino acid and pyrimidine with heavy elements followed by specific computer

The co-ordination chemistry is a very valuable and fascinating branch of chemical science. It provides the great view to study in the formation of various type complexes. In complex formation the co-ordination number or ligancy plays most important role which is the total number of atoms of the ligand that can co-ordinate the central metal ion or total number of chemical bond formed between the central metal ion and donor atoms of the ligands . The ligands whose structure permit the attachment of their two or more donor atoms to the central metal ion simultaneously and thus produce a heterocyclic ring structure said to be a chelating ligand and the complex compound is termed as metal chelate. The formation of such rings said to have chelation or cyclisation and resulting structure is called as chelate ring or simply chelate by Margan and Drew [1].Chelates are the results of the sharing of electrons between a metal and a ligand and was used to designate such cyclic structures which arise from the union of metallic ions with organic or inorganic ligands. The toxic metal ions interaction with the numerous molecules possessing groupings capable of complexation or chelation. Mixed chelation is an important phenomenon[2] in the coordination chemistry of living organisms. The peculiar interest of polydentate chelating ligands is connected with their importance [3] in agricultural industry and medicine. It has also been suggested that chelation play a vital role in cure of cancer [4]. Metal ion complex formations are among the prominent interaction in nature[5]. Heavy elemental Hg (II) and Cd (II) toxicity is a dangerous and worldwide problem. These are the cause of various disease and disorder in living beings. Metals in an oxidation state abnormal to the body may also become toxic in another oxidation state, chromium (III) is an essential trace element, but chromium (VI) is a carcinogen. We know that insoluble compounds as well as the metallic forms often exhibit negligible toxicity and this is possible by the aid of suitable chelating agents.

Essential amino acid supplementation in patients following total knee arthroplasty

tional outcomes in the long term (13), and maintaining greater muscle volume in the operated extremity is essential to maximize muscle strength (14, 15). Published reports demonstrate that after a peak in functional recovery 6 months after TKA, there is an acceleration of functional decline due to quadriceps weak- ness that outpaces normal aging and is not attributable to a lack of range of motion or pain (7, 16–18). For older adults, acute muscle atrophy and weakness are particularly debilitating, exac- erbating underlying issues related to sarcopenia, defined as the chronic loss of muscle mass and function associated with normal aging (19, 20). Sarcopenia is related to physical disability (21) and increased risk of home care (22), nursing home placement (23), and hospitalization (24). Health care costs due to sarcope- nia in the U.S. in 2000 totaled $18.5 billion (25). Thus, mitigat- ing quadriceps-specific muscle atrophy and weakness appears to be a prudent undertaking with the potential to improve quality of life for millions of older adults following TKA.

Molecular characteristics of mammalian and insect amino acid transporters: implications for amino acid homeostasis

Molecular characteristics of mammalian and insect amino acid transporters: implications for amino acid homeostasis

System A is regulated by amino acid deprivation, hormones, growth factors and hyperosmotic stress (Soler et al. 1993; Chen and Kempson, 1995). Both glucagon and insulin modulate the expression of system A (Shotwell et al. 1983; Kilberg et al. 1985). Insulin stimulates system A activity in both liver and skeletal muscle, and glucagon also stimulates it synergistically in hepatocytes (Le Cam and Freychet, 1978; Fehlmann et al. 1979; Kelley et al. 1980). In addition to being a hormone of glucose deficiency, glucagon plays important roles during periods of protein abundance, facilitating the conversion of amino acids to glucose and stimulating urea nitrogen production (Boden et al. 1990). In vitro studies on the nutrient-dependence of pancreatic glucagon and insulin release revealed different effects of individual amino acids (Ebert and Creutzfeldt, 1987; Pipeleers et al. 1985a,b). For example, alanine stimulates primarily glucagon release, leucine stimulates release of insulin but not glucagon, and arginine (a non-substrate of system A) stimulates the release of both glucagon and insulin. These responses appear to correlate with the different metabolic roles of amino acids in liver and muscle and their involvement in gluconeogenesis and ureagenesis. For example, alanine plays a key role in transamination reactions and in furnishing carbon atoms for hepatic gluconeogenesis.

Sex differences in the utilization of essential and non essential amino acids in Lepidoptera

Sex differences in the utilization of essential and non essential amino acids in Lepidoptera

We used the Carolina sphinx moth [ Manduca sexta (Linnaeus 1763): Sphingidae] from a breeding colony maintained for over 140 generations at the University of Arizona (Davidowitz and Nijhout, 2004; Davidowitz et al., 2012). Larvae were raised under a 16 h:8 h light:dark photocycle in an environmentally controlled room set at 27°C and 50% relative humidity. Larvae were fed ad libitum with a standard laboratory diet (Davidowitz et al., 2003). Pupae that were ready to eclose (19 – 25 days after pupation and 1 day before eclosion) were removed from the colony daily and isolated. We used this population as the source of the eggs, larvae and adults used in the experiments described below. Individuals from this population were also measured to establish baseline/background 13 C-values

Studies can illuminate how di fferent pollen sources meet honey bee colony nutritional needs ( Di Pasquale et al., 2016; Corby- Harris et al., 2018 ), particularly with respect to EAA ( McCaughey, 1980; Rayner et al, 1985 ) and essential fatty acid levels ( Avni et al, 2014, Zarchin et al., 2017, Arien et al., 2018 ). We found that poor bee nutrition (EAA deficiency; no-AA or NAA only) can be ameliorated with EAA diet in cages ( Fig. 4 ). Caged bees fed 1:17 EAA showed a sig- ni ficant growth increase, and developed head weights similar to colony nurse bees, and thorax weights similar to colony foragers. Overall, our colony study suggested that nutrition may drive colony growth via nurse bees. There was a signi ficant correlation (R 2 = 0.38) such that colonies with 17% heavier nurses also reared 100% more brood ( Fig. 1 A). Thus, we speculate that even modest increases in individual

• enhancing the viability of collective licensing schemes, which would entail that participants to a SSO should be allowed to collectively negotiate royalty rates on behalf of standard implementers, so as to counterbalance the strong bargaining power held by SEP-owners. In some circumstances, this would require an emphasis on the fact that, as is long established in EU and national laws, an SEP- owner’s property rights are not absolute. Moreover, this proposal should be assessed taking into account competition-related concerns, balanced with the rights of the SEP-owner. Indeed, collective licensing practices may be considered a violation of Article 101 TFEU, which prohibits restrictive agreements to the detriment of final consumers. Yet, it could also be argued that a collective licensing approach may actually benefit consumers and therefore could be exempted under Paragraph 3 of Article 101 TFEU. Indeed, collective negotiations would likely trigger competitive royalties, which could then be passed on end-consumers.

专利权作为一种私权,权利人有选择救济方式的自由,同时禁令救济 又 是 为 法 律 所 明 文 规 定 的 权 利 , 但 是 当 专 利 是 技 术 标 准 中 的 必 要 专 利 (Standard-Essential Patents),同时标准必要专利权人在已就其专利做出过 符合“公平、合理、非歧视(FRAND)”原则的许可承诺情况下,专利权 人是否还有权寻求禁令救济?如果有,应该对哪些因素进行何等衡量?在 实务中,是否有可行的解决模式?这些问题不仅在理论上很有研究价值, 对产业界也很有现实意义。笔者通过对美国、欧洲关于技术标准中必要专 利的禁令救济的最新政策文件、典型案例和学术界观点的分析研究,认为: FRAND 承诺并不必然排斥专利权人的禁令救济权,但是也不应该当然适 用该等救济方式,而是应该基于个案的具体情况仔细权衡禁令可能对标准 必要专利权人的利益、公共利益、标准使用者的利益以及对市场竞争所带 来的影响。对于衡平的标准,笔者认为应该尽量做到一方面要保证专利制 度设计初衷之鼓励发明、促进技术进步、促进经济发展得以实现,同时又 要避免禁令妨碍市场竞争,最终影响社会福利。这些利益之间的权衡标准 往往取决于判断者对于各种利益的价值判断,很难有标准答案。在具体解 决模式上,笔者认为可以在“禁令生效前的许可谈判模式”的基础上进行 部分改进,最终的目的是要逼迫当事人双方回到谈判桌上进行诚信的许可 谈判。同时,笔者建议我国法院在涉及标准必要专利禁令问题时能够参照 美国的“法庭之友”模式,广泛邀请社会公众就其中的某些问题发表意见。
