人类生育英文作文

人类生育英文作文英文:Human reproduction is a fascinating and complex process. It involves the fusion of a sperm and an egg, which results in the formation of a zygote. This zygote then undergoes a series of cell divisions and differentiation to eventually form a fetus.The process of human reproduction begins with the release of an egg from a woman's ovary during ovulation. This egg then travels through the fallopian tube towardsthe uterus. Meanwhile, sperm are released during sexual intercourse and swim towards the egg. If a spermsuccessfully penetrates the egg, fertilization occurs and a zygote is formed.The zygote then undergoes a series of cell divisionsand differentiation to form an embryo. The embryo implants itself in the lining of the uterus and continues to develop.Over the course of several weeks, organs and tissues begin to form, and eventually a fetus is formed.It's important to note that human reproduction is not always straightforward. There are many factors that can affect fertility, including age, genetics, and lifestyle choices. Additionally, there are many medical interventions available to assist with reproduction, such as in vitro fertilization (IVF) and surrogacy.中文:人类生育是一个迷人而复杂的过程。

尼莫地平PLGA微球的制备方法改良及其特性研究

尼莫地平PLGA微球的制备方法改良及其特性研究

摘要尼莫地平(nimodipine,NMP)在临床上常被用为选择性作用于脑血管平滑肌的钙拮抗剂,己成为治疗脑血管疾病的首选药物。

针对其体内半衰期短,口服生物利用度低,须频繁给药,且副作用较严重等问题,本文将其微囊化以提高NMP的临床应用价值。

研究利用乳化-溶剂挥发法将NMP进行微囊化,载体材料采用生物可降解材料聚乳酸-羟基乙酸共聚物(PLGA)。

为了通过易挥发潜溶剂的使用来调节微球的固化速率,在油相溶剂中引入高挥发度的石油醚与二氯甲烷(DCM)作为混合溶剂,考察了石油醚与DCM的混合比例对载药微球的影响;另外考察了不同乳化剂、聚合物分子量、聚合物浓度、投药比等因素,并进行了正交优化设计。

研究还考察了减压条件下微球的制备,并与常压下优化所得的微球进行了比较。

另外,对载药微球进行了初步稳定性考察。

结果表明,聚合物分子量增大及浓度的提高均会提高油相的粘度从而增大微球的平均粒径,载药量,并降低突释率;投药比超过1:15时会在微球表面产生:V DCM = 0、1:10、药物结晶且突释率增大;随着油相中石油醚比例的增大(V石油醚1:8、1:4、1:2),微球的固化速率有不同程度的增大,从而影响微球的载药能力与体外释放等特性。

正交优化后,微球包封率(EE)相对于优化前提高52.2%,突释率相对降低58.8%,所得微球粒度分布均匀,外表光滑致密,缓释效果增强(25 d后累积释药率约80%),体外释药动力学研究结果表明药物释放遵循扩散和骨架溶蚀共同控制的机制,且工艺重现性良好;优化组载药微球与以DCM为单一溶剂制得的微球相比,包封率有小幅提高,形态改善显著;另外,石油醚的使用未改变药物与聚合物的物理存在状态,而在较小程度上降低了聚合物的玻璃化转变温度(T g)。

利用减压去除溶剂法,所得微球包封率较常压下高(EE>50%),但因其表面的少量结晶,体外释放速率较快(18 d时累积释药率即可达到80%左右)。

NMP微球初步稳定性试验结果表明,微球对湿、热及强光不稳定,宜在低温,低湿及避光条件下保存。

Asia.Interestingly,patchouli essential oil is also used in cosmetics,deodorants and insecticides.Recently,essential oil produced by P.cablin (Blanco)Benth is thought as the most important bioactive material which contains various sesquiterpenes and hydrocarbons,such as patchouli alcohol (patchoulol),patchoulene,bulnesene,guaiene,caryophyllene,elemene,and copaene [4].Herein,the present paper first gives an overview of patchouli’s chemical components and quality evaluation.In particular,the bioactive compounds contained in essential oil and some nonvolatile chemical compounds,such as flavonoids and glycosides,in P.cablin are summarized.Furthermore,we highlight the pharmacological activities of P.cablin derived from the above chemical compositions.Finally,we discuss P.cablin ’s market profile and identify 41kinds of preparations containing P.cablin that are available on the market,including pills,tablets,granules,capsules,liquids,and medicinal wine,made by five kinds of extraction methods.2.Chemical componentsNow,rapid advancements have been made in chemical constituent analysis of P.cablin ,generally dividing it into vol-atile and nonvolatile compounds.First,focus has been on the volatile oil from its leaves and stems,as the main active ingre-dient,and it has been discovered that there are several kinds of compounds including monoterpene,sesquiterpene and micromolecular alcohol.Ling et al.[1]identified 33com-pounds from volatile oil of P.cablin for the first time,which mainly contained patchouli alcohol (31.86%),seychellene (9.58%),a -guaiene (8.82%),d -guaiene (8.65%),a -patchou-lene (8.48%),b -patchoulene (6.91%),pogostone (3.83%),using gas chromatography --mass spectrometry (GC-MS).Similarly,24compounds were reported by Zhang et al .whose content were mostly 96%of total volatile oil.Some volatile oil compounds,including geranium ketone,7-patchoulene,a -patchoulene,a -bulnesene,5-cedrol and eucalyptus oil ketene.Additionally,four new patchoulene derivatives,namely 8a ,9a -dihydroxypatchoulol,3a ,8a -dihydroxypatchoulol,6a -hydroxypatchoulol and 2b ,12-dihydroxypatchoulol,were isolated from the aerial part of P.cablin (Labiatae)’s,four sesquiterpenoids:namely (5R)-5-hydroxypathoulol,(9R)-9-hydroxypatchoulol,(8S)-8-hydroxypatoulol and (3R)-3-hydroxypathoulol [7].The structures of main terpenoid compounds in volatile oil of P.cablin are shown in Figure 1.Although most studies focused on the analysis of volatile compounds,nonvolatile compounds in P.cablin are still increasingly reported.Guan et al.[8]obtained two flavones,retusine (1)and pachypodol (2),from P.cablin.And then,several flavones in the nonvolatile constituents,including 5-hydroxy-3,4¢,7-trimethoxyflavone (3),5-hydroxy-4¢,7-dime-thoxyflavone,5¢-hydroxy-3¢,4¢,7-trimethoxyflavanone,3,3¢,4¢,5,7-pentahydroxyflavone (4),3,5-dihydroxy-4¢,7-dimethoxy-flavone (5),4¢,5-dihydroxy-7¢-methoxyflavone (6),ombuine (7),apigeni n (8),rhamnetin (9),apigetrin (10),apigenin 7-O-b -D-(-6¢-p-coumaroyl)-glucoside (11),respectively were isolated by Zhang et al.[9]and Itokawa et al.[10]using column chromatography.Additionally,Huang et al.[11]totally isolated four flavonoid glycosides,including isorhamnetin-3-O-b -D-galactoside (12),hyperoside (13),3,5,8,3¢,4¢-pentahydroxy-7-methoxyflavone-3-O-b -D-galactoside (14)and isisolidone-7-O-a -L-rhamnopyranoside from the ethanol extract of stem leaf of P.cablin.Meanwhile,some flavonoids isolated from P.cablin and identified by spectrum were reported [12]as follows:4¢,5-dihydroxy-3¢,7-dimethoxyflavanone (I),5-hydroxy-7,3¢,4¢-trimethoxyflavanone (II),3,5-dihydroxy-7,4¢-dimethoxy-flavone (III),5-hydroxy-3,7,4¢-trimethoxyflavone (IV),5-hydroxy-3,7,3¢,4¢-tetramethoxyflavone (V),5,4¢-dihy-droxy-3,7,3¢-trimethoxyflavone (VI),5,4¢-dihydroxy-7-methoxyflavone (VII),3,5,7,3¢,4¢-pentahydroxy-flavone (VIII),5,7,4¢-trihydroxyflavone (IX),and 3,5,4¢-tri-hydroxy-7-methoxyflavone (X).Similarly,Ding et al.studied the n -butanol extraction of ethanol extract of the aerial parts of P.cablin ,obtaining several glycosides from it,including apigenin 7-(O-methylglucuronide),apigenin 7-galacturonide,luteolin 7-O-(6-O-methyl-b -D-glucuronopyranoside),querce-tin-7-b -D-glucoside,syringaresinol-b -D-glucoside,verbascoside,orobanchoside and campneoside I [13].The structures of some main flavonoids found from P.cablin are shown in Figure 2.In recent years,apart from these flavone compounds,there are also some other chemical types of nonvolatile compounds separated from P.cablin (Figure 3).Two new rearranged patchoulene sesquiterpene glycosides from P.cablin ,3a -hydroxypatchoulane 3-O-b -D-glucopyranoside (I)and 15-hydroxypatchoulol 15-O-b -D-glucopyranoside (II)were found [14].Researchers including Guan et al.[8],Treasure [15]and Itokawa et al.[10]obtained friedelin (III),epifriedelinol (IV),oleanolic acid (V),b -sitosterol (VI),eugenol (VII),cinnamaldehyde (VIII),benzaldehyde (IX),patchoulipyridine (X),epiguaipyridine (XI),daucosterin (XII).Article highlights..Pogostemon cablin ,a well-known Chinese materia medica in southeast Asia,has been widely used ingastrointestinal disease and exterior syndromes clinically..Systematic review on the pharmacy research and market performance of P.cablin has been reported for the first time..Although both chemical analysis and therapeutic effects of P.cablin have been reported substantially,there are still greatly required for in-depth study on its molecular mechanisms,bioactive targets,the qualitative,and quantitative standard of P.cablin ..Appropriate extracting methods of P.cablin need to be studied deeply..Novel dosage forms are required to be developed for P.cablin .This box summarizes key points contained in the article.M.Chen et al .246Expert Opin.Investig.Drugs (2013)22(2)E x p e

人类受精与胚胎学法案 英文

人类受精与胚胎学法案英文The Human Fertilisation and Embryology Act (HFEA) is a piece of legislation in the United Kingdom that regulates assisted reproductive technologies, including in vitro fertilisation (IVF), embryo research, and the storage and use of gametes and embryos. The Act was first passed in 1990 and has undergone several amendments since then to keep up with scientific advancements and social changes.The main objectives of the HFEA are to protect the safety, welfare, and dignity of those involved in assisted reproduction and embryo research, while also promoting the development and use of these technologies to the benefit of society. The Act sets out strict guidelines and regulations for clinics and researchers, including licensing requirements, staff qualifications, and ethical standards.One of the key provisions of the HFEA is the creation of the Human Fertilisation and Embryology Authority (HFEA), an independent regulatory body responsible for ensuringcompliance with the Act. The HFEA licenses and inspects clinics and research facilities, investigates complaints, and enforces sanctions against those who violate the law.It also provides guidance and advice to clinics and researchers on ethical and best practice issues.One of the most controversial areas covered by the HFEA is the use of embryos for research purposes. The Act allows for the creation and use of embryos for research, but only under strict conditions and with the explicit consent of the donors. Embryos must be destroyed after a certain period of time, and no embryo can be implanted into a woman's womb for the purpose of creating a child. These restrictions are designed to protect the dignity and rights of the embryo, as well as to prevent the commercialisation of human reproduction.Another important aspect of the HFEA is its focus on the welfare of children born through assisted reproduction. The Act requires that children born through IVF and other assisted reproductive technologies have the same legal status as naturally conceived children, and that theirparents have the same rights and responsibilities as any other parents. This ensures that children born through assisted reproduction are not discriminated against and have the same opportunities and protections as other children.Overall, the Human Fertilisation and Embryology Act has played a crucial role in regulating and guiding the development of assisted reproductive technologies and embryo research in the United Kingdom. It has struck a balance between promoting scientific progress andprotecting the rights and welfare of those involved, while also ensuring that new technologies are used ethically and responsibly. However, as science continues to evolve and social attitudes change, the HFEA and the law it governs will need to adapt and evolve as well.。

Abstract: The stages of introduction in vitro culture of the local population of the kidney tea (Orthosiphon stamineus Bents) cultivated in the Georgia’s medicinal plant farm and the microclonal propagation, in particular, have been elaborated. The cultivation of explants was carried out on the Gamborg (B5) feeding area. The hormonal (BAP; Zn; NAA) composition of the feeding area and their concentrations have been selected; proliferation of buds in the basal part of the sprout has been achieved from the formed morphogenic tissue. The microclones by activating axillary meristem have been received.

Key words: Kidney tea, in vitro culture, reproduction, plant regeneration, micropropagation, phytohormones, adventive buds. 1. Introduction High ability to regenerate plant and cell in vitro culture makes it possible to maximize the ability of getting full-fledged plants from somatic tissue. The proliferation induction of the axillary meristems of the isolated organs is connected to the hormonal balance of different plant organs, the transportation of phytohormones and to the supply of buds with trophic factors [1]. During the insufficient restoration of the organs by the isolated parts and the regeneration of the perfect plant, the correlation among the whole plant organs is violated and at the same time this correlation is compensated, which results in the compensation of the balance in the organism. This is the most common method of regeneration in higher plants, based on the methods of vegetative, as traditional propagation as well as on the methods of cell and tissue culture [2, 3]. These processes are regulated by phytohormones. The selection of concentration of phytohormones in the feeding area is carried out by visual observation on the reaction of the explants based on the trial and error. However, we should note that there is no ideal formula for the type and concentration of phytohormones in the

feeding area. The aim of our experiment was to obtain sterile cultures of local population of kidney tea (Orthosiphon stamineus Bents) (Fig. 1) cultivated on the farm of medicinal plants of Georgia (Kobuleti); to develop and optimize microclonic propagation conditions. As known from the scientific literature, various experiments have been conducted by various scientists, around Orthosiphon stamineus in vitro cultivation; the efficacy of micropropagation in these works has been achieved by the activation of the meristematic tissue of buds and the induction and regeneration of the callusing on the MS feeding area with various hormonal composition [4-6]. The kidney tea brought into culture in the subtropical regions of Georgia is a one-year culture, strongly branched evergreen bush with a height of 70 cm. The root system is brush-like and strongly branched. The stems are square; the leaves are short-stalked and oppositely arranged. The leaves in the lower part of the stem are downy along the vessels, the flowers are mild-violet, androgynous. The scorpioid creates pyramidal cluster; the fruit consists of 1-4 seeds; blossoms in July-September. Leaves and sprouts used for treatment contain triterpenoid saponins, flavonoids, fustic substances, ether oil, lipids, organic acids: wine,

lemon phenolcabon, and rosemary acids. Kidney tea is mainly used as a diuretic mean for acute and chronic diseases of kidneys, including cystitis, urethritis, diabetes, cholecystitis, gallbladder disease, heart diseases, which are accompanied by swelling. It removes the urea, uric acid and chlorides from the organism. Taking renal tea is very effective and it does not have contraindications. Due to the above features, getting the seedlings of kidney tea is very important for plant experimental stations and farms. The need for seedling material is great enough to ensure the traditional methods of multiplication, so this problem was solved by developing the tissue culture technology.
